(MAYNILAD), and the Land Bank of the Philippines (LBP) have agreed to implement the Muntinlupa Sewage Treatment Water Quality Improvement Project as a component of the Metro Manila Wastewater Management Project (MWMP). Overall, the MWMP aims to increase the coverage and effectiveness of wastewater collection and treatment in Metro Manila and its suburbs. The MWMP supports the National Sewerage and Septage Management Program (NSSMP), as required under the Philippine Clean Water Act as well as Government efforts to clean up the Laguna de Bay and other water bodies. The Maynilad together with the Manila Water Company, Inc. (MWCI) are the two concessionaires of Metropolitan Waterworks and Sewerage Services (MWSS) assigned to manage the water supply, sewerage, and sanitation services in Metro Manila. Improvements in wastewater services are priorities for both companies. To achieve 100 percent coverage, both concessionaires have prepared investments in wastewater management in their business plans using a river basin approach and with investments planned at the sub-catchment level to collect and treat wastewater. For MAYNILAD’s service area in Muntinlupa City, a two-stage conveyance and sewerage service system is proposed. The first stage will consist of two (2) STPs, one in Barangay Cupang and another one in Barangay Tunasan. The 2nd stage will be the capacity upgrade of the STP in Barangay Tunasan. The project proposed for financing and immediate implementation is the first-stage STPs that will both drain in Laguna Lake . To reduce the pollution load being discharged into the rivers and streams that flow through the Muntinlupa catchment, the MAYNILAD proposes to construct a 46 and 20 MLD capacity STPs to be located in Bgy. Cupang and Bgy. Tunasan respectively. Muntinlupa catchment is divided into six (6) sub-catchments based on the topography of the inclusive river basins, Sub- catchments: A- Buli River, B-Pasong Diablo River, C- Bayanan River, D- Poblacion River, E- tunas an river and F- San Pedro River. Sub-catchments A,B,C,E anf F will be service in Stage 1, while Stage 2 will extend service coverage to include sub-catchment D catering the whole of Muntinlupa. The flows will be conveyed via streams towards creek interceptors’, where the wastewater flow will be diverted to a conveyance. The conveyance generally runs along M. L. Quezon, Ilaya, San Guillermo St. and other small roads in some portions. Flows intercepted will be conveyed to the treatment plant prior to reaching Laguna Lake. This report gives an account of the environmental assessment of the proposed project that was conducted as part of the project preparation and planning. The environmental assessment aims to identify and assess the potential impacts of the proposed project on the environment, and to recommend measures to mitigate the potential adverse impacts arising from its implementation. 7|Page TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 1.1 Project Rationale Overall, the proposed project aims to:  Enhance management of wastewater, human waste and storm water;  Reduce pollution load being discharged into rivers and creeks;  Contribute to the clean-up of creeks and rivers draining Laguna de Bay;  Comply with the National Sewerage and Septage Management Program under the Philippine Clean Water Act;  Contribute to economic growth in Metro Manila, particularly Muntinlupa City; and  Improve public health and sanitation in the urban environment. 1.2 Summary of Project’s Environmental Assessment Process 1.2.1 Policy, Legal, and Administrative Framework 1.2.1.1 World Bank’s Environment Safeguards Requirements The World Bank Safeguards Policies is outlined in OP/BP 4.01. Considering that the project will be financed through LBP as Financial Intermediary, the entire project has been categorized as FI and LBP as borrower will ensure that the WB’s policies as well as relevant national regulations are followed, and appropriate instruments prepared. However, the sub-project is classified as a Category B project. Specifically for the MWMP, an Environment and Social Safeguards Framework (ESSF) was already drafted. Environmental screening of the project is required to identify key potential environmental issues and to determine the environmental category of the project. Annex A presents the Environmental Screening checklist that was prepared for the Muntinlupa STP project. The following are the environment safeguard policies of WB that might apply to the proposed project: Environment Status Remarks Safeguard Policies Yes No OP/BP 4.01 –  Based on the Environmental Screening and ESSF, it was Environmental deemed that the project falls under Category B and Assessment therefore, requires an Initial Environmental Examination (IEE) and an Environmental Management Plan (EMP). MAYNILAD shall be responsible for the implementation of the EMP, subject to regular visits throughout project implementation by LBP. OP/BP 4.04 – Natural  The project is located in an urban environment. It will not Habitats cause any loss or degradation of natural habitat, but rather will contribute to the regeneration of the Laguna de Bay that is currently degraded. Existing trees within the site can be preserved through site development planning. OP/BP 4.2 Involuntary  The STP site is a private property. Fifteen ISs families Resettlement were properly informed as to the plan of the land owner to sell the lot they are occupying. They are willing to vacate their present location of residence and be relocated. Each of the IS were given financial assistance for their affected structures and relocation. A relative of the land seller 8|Page TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report offered her available lot, 40 meters away from the PAPs present location, to be the relocation site of the PAPs and is willing to sell the lot to the at a low price. There are no resettlement issues involved at along the conveyance system. Chance Finds  The project sites are highly developed and are not declared as cultural or heritage sites by the National Museum. OP 4.10 Indigenous  Not applicable. Peoples Policy 1.2.1.2 Philippines Legal and Regulatory Requirements The Philippine implements an Environmental Impact Assessment (EIA) system by virtue of the Presidential Decree 1586 or the Environmental Impact Statement (EIS) system. P.D. 1586 was originally devised as an administrative procedure for an action‐ forcing policy that requires proponents of development projects to systematically study and disclose the environmental impacts of their projects. In accordance with Presidential Decree 1586, development projects are required to conduct an EIA and to prepare environmental assessment reports for review and approval of the Environmental Management Bureau (EMB) prior to the issuance of an Environmental Compliance Certificate (ECC). Aside from the ECC, there are other environmental permits and approvals that are necessary prior to the implementation of the proposed project, as follows: Table 1. Other Environmental Permits Applicable to the Proposed STP Project Permit/Clearance Issuing Purpose Agency Permit to Cut/Ball Out Trees DENR-FMB Applicable if the proposed project will cut/ball out trees LLDA Clearance LLDA Muntinlupa City falls under the jurisdiction of LLDA in terms of wastewater management. Discharge Permit LLDA For operation and maintenance of the STP Permit to Operate – Air Pollution DENR-EMB Applicable if the proposed project will utilize Source Equipment generator sets even if as standby units only Hazardous Waste Registration DENR-EMB For generation of hazardous wastes such as empty chemical containers, used oil, busted fluorescent lamps. 1.2.2 EIA Study Schedule & Area The Environmental Impact Assessment (EIA) study was conducted in March to April 2013. The EIA study area comprises of the catchment area, sites of the conveyance system, and the project site of the proposed STP as primary impact area. The primary impact area is defined as the immediate vicinity to the perimeter up to a radius of 10 meters. This includes part of the adjoining residential houses, commercial establishments in the vicinity, and the streets traversed by the gravity line interceptors and conversion manholes. Sensitive receptors within the primary impact area were identified in the environmental assessment. The primary impact area was determined based on the potential impacts that may 9|Page TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report be generated by the project particularly during the construction phase. These environmental impacts include generation of dust, noise, soil runoff, and traffic that may cause nuisance and hazards to the environment, residents and passersby, impacts to existing utilities, waste generation and disposal, among others. The secondary impact area is defined as the area within 500-m radius of the proposed project site components wherein a greater number of populations will be affected either directly or indirectly by the potential environmental, health, and socio-economic effects of the project. The secondary impact area is projected to experience impacts associated with improvement of sanitation, community health condition, improvement of water quality of Laguna de Bay , among others. 1.2.3 EIA Methodology The conduct of the EIA study was guided by the World Bank Safeguards Policies, draft Environment and Social Safeguards Framework of the MWMP, and the Implementing Rules and Regulations of Presidential Decree No. 1586 which is contained under DENR Administrative Order No. 30 Series of 2003 (DAO 2003-30). This EA report includes information and data on the following:  General description of the environment of the project area and the need for the project  Project goals and objectives  Project scope  Environmental concerns  Environmental management plan  Environmental monitoring plan. This report presents the primary and secondary data gathered during surveys held in March to April 2013 as well as results of studies commissioned by MAYNILAD during the Feasibility Study (FS) of the project which was completed in June 2011. Activities include survey/data gathering on water quality, air quality, noise, flora and fauna, and socio-economic profiling to characterize the environmental conditions and to further define the environmental impacts of the project. 10 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Figure 1.

The consultation meeting aims to solicit ideas, suggestions, comments and concerns about the project. Representatives from the local residents of Tunasan, members of Barangay Council of Tunasan, and representatives of several housing associations attended said public consultation. Maynilad explained that the project will help improve the prevailing unsanitary conditions in the community and is designed to intercept wastewater flows coming from the drainage system to be diverted to the proposed STP for treatment. One of the relevant questions raised during the public consultation was regarding the locations of pipelaying for the conveyance system of the proposed STP. President of Park Homes Village HOA, asked if the conveyance will be laid in the different HOA subdivisions in Tunasan and will the project timeline consist of ROW acquisition in those areas. Maynilad clarified the inquiries by presenting the scheme to be used in Muntinlupa South Catchment. The project will be implementing a creek interception and pipelaying will be implemented along Buendia St. in Tunasan. The scheme will eliminate pipelaying in subdivisions and villages therefore avoiding inconvenience for both Maynilad and the HOA. Another question raised was the roles and responsibilities of the LGU in the project. Maynilad explained that the LGU will play a vital role especially in solid waste management. The local government of Muntinlupa as well as the community is expected to be vigilant in implementing effective solid waste management such as the dumping of wastes in waterways to prevent clogging and blocking of the drainages and rivers. The success of the project lies on the proper and effective management of solid wastes. Maynilad will provide screens in the conveyance manholes and interceptor box. However, if screens will be obstructed with solid waste, wastewater flow to the STP will be reduced and the flow will be diverted to the nearest manhole which may cause flooding of the streets. Maynilad will provide the services in reducing the pollution load being discharged into the rivers and streams by treating the wastewater that will be conveyed via streams towards creek interceptors and the intercepted flows will be conveyed to a treatment plant for treatment prior to reaching Laguna de Bay. The members of the Barangay council expressed their willingness to cooperate with Maynilad for the timely completion of the project. 12 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report The minutes of the public consultation meeting is presented in Annex B. 1.2.4.1 Future Public Participation Plans Plans for public involvement during the construction and operational phases of the project will be developed, once the construction program is better defined. These plans will provide forums for updating stakeholders periodically on project progress and the implementation of mitigation measures. These plans will be incorporated into an IEC plan. 2 Project Description Maynilad Water Services, Inc. (MAYNILAD) proposes to construct a 20-MLD sewage treatment plant (STP), conveyance system, pump stations and other appurtenances to handle wastewater flows into the Laguna Lake. The proposed STP will serve a hydrological catchment area of 2,550 ha. The The project will be referred to as the “Tunasan Sewage Treatment Plant” project. The Tunasan STP’s catchment area primarily covers sub-catchment 2 (see Figure 2) or it covers three sub-catchments from the Muntinlupa wastewater catchment, based on the topography of the inclusive river basins namely: a) Sub-catchment D -Tunasan River; b) Sub-catchment E -Poblacion River; c) Sub-catchment F -Pasong Diablo River The plant is situated some 65 meters north from the road going to the Muntinlupa Sports Complex, 215 meters north from the Buendia and Arandia Street junction, 700 meters north of the corner of Arandia Street and Rodriguez Jr. Street and 1,300 meters northeast from the corner of the National Highway and Rodriguez Jr. Street. Buendia Street, the main access road to the site, is 5 meters wide and cemented The proposed STP will be built in a property covering a consolidated land area of 8,333 sqm parcel of land located east of Buendia Street, within Bo. Tunasan, Muntinlupa City, Metro Manila. The land consists of various lots owned by different individuals. It is situated some 65 meters north from the road going to the Muntinlupa Sports Complex, 215 meters north from the Buendia and Arandia Street junction, 700 meters north of the corner of Arandia Street and Rodriguez Jr. Street and 1,300 meters northeast from the corner of the National Highway and Rodriguez Jr. Street. Buendia Street, the main access road to the site, is 5 meters wide and cemented.. The STP site is approximately centered by geographic coordinates 14031’54.39” north latitude and 121000’28.88” east longitude. A combined sewer collection system will be applied by the project. Wastewater will be collected through street drainage lines with outfalls alongside the rivers and creeks in the catchment area. Downstream river flows will be conveyed via streams towards creek interceptors’, where the wastewater flow will be diverted to a conveyance. The conveyance generally runs along ML Quezon, Ilaya, San Guillermo St. and other small roads in some portions. Flows intercepted from the rvers/creeks will be conveyed to the treatment plant prior to reaching Laguna Lake. The system will be provided with overflow structures to prevent 13 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report excess flows to the STP during heavy downpour. The treated effluent from the STP will be discharged through an outfall into the Laguna de Bay. Muntinlupa City lies within 14o23’ north latitude and 121o03’ east longitude and is located on the Southwestern Coast of Laguna de Bay. It is bounded on the North by Taguig, on the Northwest by Parañaque, on the West by Las Piñas, on the Southwest by the Province of Cavite, South by the Province of Laguna and on the East by Laguna de Bay. It is 22 kilometers South of Metro Manila, easily accessible to all points of Metro Manila through the National Highway and South Luzon Expressway. . 14 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Figure 2.

Muntinlupa Wastewater Catchment 16 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report A watershed approach was developed whereby the Muntinlupa catchment area was subdivided into six sewerage sub-catchments (see Figure 3). The delineation was based on topography, location of candidate STP sites, and existing drainage collection systems. The hydrological catchment corresponding to this project area is the sum of six sub-catchments named after the local rivers. The natural outlet of these rivers is Laguna Lake. The total land area of the hydrological catchment is approximately 4,750 ha. The hydrological catchment has a natural extension in San Pedro, Laguna and part of the storm water in this area may drain into the river boundary between Muntinlupa and San Pedro. These sub-catchments are: • Sub-catchment Area A - Buli (750 ha) • Sub-catchment Area B - Pasong Diablo (1,400 ha) • Sub-catchment Area C - Bayanan (400 ha) • Sub-catchment Area D - Poblacion (1,100 ha) • Sub-catchment Area E - Tunasan (500 ha) • Sub-catchment Area F - San Pedro (600 ha) • The wastewater catchment of Muntinlupa is bound by its municipal boundaries. The eastern boundary of the catchment is Laguna Lake while Daanghari forms the western boundary. South of the catchment is bounded by San Pedro River, which forms the boundary between Muntinlupa and San Pedro, Laguna. The northern portion of the catchment is bounded by the Municipal boundary of Taguig. Table 3.

The practice of dumping untreated wastes into these water bodies would continue to contribute to degradation of water quality, worsen sanitation and health conditions in the community, aggravate flooding, and result to the overall deterioration of the living conditions of the communities particularly those living near waterways. 2.1.3 STP Siting Alternatives Six (6) STP site locations were investigated by MAYNILAD as viable candidates, all of which are near Laguna Lake. The candidate STP site locations were selected based upon the following criteria: a) Land area b) Proximity to a discharge point c) Access d) Location within the catchment (upstream/downstream) e) Site conditions f) Land type g) Avoidance of informal settlers h) Maintain about a kilometer radius buffer zone from Putatan Water Treatment Plant Table 4 listed the five option sites for the Muntinlupa STP also refer to Figure 4 for its aerial map.

Site Locations of STP Alternatives 20 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 2.1.4 Interception Options In the feasibility study three options were developed for the Muntinlupa conveyance which differ on methodology. These are: interception at points upstream of the creek embankments; conveyance through a pipeline under a concrete lined creek bed; and creek conveyance to downstream interception via creek interceptor weirs. Conveyance through the creek beds to an interceptor weir (Option C) is preferred and recommended due to its advantages in terms of cost, constructability and overall pollution reduction. Hence, all conveyance options developed are based on the the concept of interception Option C. The three interception options are discussed below: Option A - Outfall Interception Prior to Pollutants Reaching Creeks. This option relies on availability of suitable access and roads generally following the creeks’ path. Such, in the case of Muntinlupa is a very severe limitation, particularly due to the lack of access to the stormwater outfalls to creeks. Prior to reaching the streams, flows from outfalls would be diverted by means of pump stations or by gravity to a series of sewers which will run generally parallel to the streams then collected by a main line parallel to the Laguna shore. Spine sewers would ideally be laid along the road network to minimize ROW issues. However, the interception of outfalls, in a significant number of cases, would inevitably mean entering properties, particularly those closer to the creeks; which, in majority of cases, are informal settlements. Any attempt to intercept the existing drains prior to entering the creek will require at least one or a combination of these following strategies:  Potential relocation of existing residents  Structural works within private property and restoration  Extensive residential/stakeholder consultation  In addition to the above, identifying and procuring suitable locations for pump stations in locations not yet finalized will also be a significant challenge. Due to the significant disadvantages stated above, the Feasibility Study considers this option to be a less preferred option. Option B – Creek Lining, Interception and Conveyance The general concept of this option is to lay pipes along concrete-lined creeks/rivers. An interceptor box would be installed at every 50m length of river bed. Intercepted flows would be collected and conveyed to the trunklines lying along the river bed. To avoid the possible scouring of the river bed on the pipes of the main trunk, the river would be lined by about 250mm of concrete and a layer of mesh. Infrastructure and appurtenances required for this option are pipes for conveyance, manholes, interceptor boxes, at least one pump station, concrete creek/river lining, wire mesh and a temporary bypass system for diverting the river flow during construction. 21 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report In terms of social perception, this option is favorable to the public because it directly and almost immediately improves the creek conditions. Also, it does not require major relocation of existing tenants along the river easements, which is where most of the informal settlements of Muntinlupa are residing. In some Muntinlupa creeks, however, informal settlements have gone as far as stilting over the waters. Concrete lining and temporary bypass systems may require relocation for this case. Temporary bypass set- ups and interceptor box installations may cause disruptions, as well, and require area on some, if not all, interception points. This methodology is comparatively costly in terms of construction and appurtenances. This alternative, although full of potential, is expensive and has significant disadvantages (i.e. relocation of informal settlements in certain points). Therefore, it is considered to be a less preferred option. 22 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report NOTE: The presence of retained wall/earthen lined channel varies along the drainage creek Figure 5. Typical Creek Plan and Section 23 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Option C - Creek Interception and Conveyance This option utilizes creeks and small streams as conveyance to a main interceptor system along Laguna Lake and intercept the Dry Weather flow-borne pollutants by means of interceptor weirs The key advantages to this option are: a) Simplified Construction b) Simplified Operation & Maintenance c) Preclusion of multiple pump stations and rising mains d) Minimal ROW, land acquisition and stakeholder concerns e) Provision for channel upgrade, such as building adjacent sewer in creek line, or lining the creek channel f) Provision for separate system upgrade The majority of the outfalls also follow the creeks as shown in Figure 7A, 7B and 7C. This, in addition to the list above makes creek interception advantageous. A specific “Creek Interceptor” conceptual design has been developed and it is shown on Figure 6A and Figure 6B. The disadvantage on using creeks and small streams as conveyance with the installation of interceptor weirs is it may affect water flow along creeks as it will be used to capture wastewater from various areas around Muntinlupa. As a result of this, the flow of water downstream of the interceptor weirs may potentially decrease or cause the creek to dry up. Figure 6A.

Wastewater sub-catchments served are the same as the river sub- catchment shown in Figure 3. This is due to the application of creek interception to Muntinlupa, instead of outfall interception. 2.1.5.2 Stage Timing Conveyance system coverage is proposed into two stages which has been generally aligned with MAYNILAD targets as shown in Table 5. Table 5. Conveyance Stage Timing Stage Timing 1 Commence by 2012 2 Commence between 2016 and 2021 2.1.5.3 Conveyance Options Considered In the Feasibility Study seven conveyance options were assessed. Two options have been shortlisted as preferred options: Option 5 and 6 for utilizing available public land. Option 5 uses PNR as main corridor while Option 6 uses roads approved by the municipality. The seven conveyance options are shown in Table 6. Table 6. Conveyance Options OPTION STRATEGY 1 Flows will be conveyed via streams mainly towards creek interceptors’ locations, where the dry weather flow will be diverted to a main trunkline acting as the conveyance. This trunkline generally runs along the ML Quezon road and other small roads in some portions. Flows intercepted from the rivers/creeks will be conveyed to two treatment facilities, S1 and S3 . 2 Flows will be conveyed via streams mainly towards creek interceptors’ locations, where the dry weather flow will be diverted to a main trunkline acting as the conveyance. This trunkline generally runs along the ML Quezon road and other small roads in some portions. Flows intercepted from the rivers/creeks will be conveyed to one treatment facility, S1 prior to reaching Laguna Lake, with Area A being serviced at Stage 1 followed by Service Area B at Stage 2. 3 Flows will be conveyed via streams mainly towards creek interceptors’ locations, 29 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report where the dry weather flow will be diverted to a main trunkline acting as the conveyance. This trunkline generally runs along the ML Quezon road and other small roads in some portions. Flows intercepted from the rivers/creeks will be conveyed to S2 prior to reaching Laguna Lake, with Area A being service at Stage 1, followed Service Area B at Stage 2. 4 Flows will be conveyed via streams mainly towards creek interceptors’ locations, where the dry weather flow will be diverted to a main trunkline acting as the conveyance. This trunkline generally runs along the ML Quezon road and other small roads in some portions. Flows intercepted from the rivers/creeks will be conveyed to S1 and S2 prior to reaching Laguna Lake, with Area A being service at Stage 1, followed Service Area B at Stage 2 . 5 Flows will be conveyed via streams mainly towards creek interceptors’ locations, where the dry weather flow will be diverted to a main trunkline acting as the conveyance. This trunkline generally runs along the Philippine National Railway (PNR) that is within the Muntinlupa municipal boundary. Flows will be ultimately conveyed to S4 prior to reaching Laguna Lake, with Area A being serviced at Stage 1, followed by Service Area B at Stage 2. . 6 Flows will be conveyed via streams mainly towards creek interceptors’ locations, where the dry weather flow will be diverted to a main trunkline acting as the conveyance. Majority of this trunkline runs along the ML Quezon road, other small roads and several meters along the PNR in some portions. Flows will be ultimately conveyed to S4 prior to reaching Laguna Lake, with Area A being service at Stage 1, followed by Service Area B at Stage 2. 7 Flows will be conveyed via streams mainly towards creek interceptors’ locations, where the dry weather flow will be diverted to a main trunkline acting as the conveyance. This trunkline generally runs along the ML Quezon road, other small roads and several meters along the PNR in some portions. Flows intercepted from the rivers/creeks will be conveyed to S4 and S5 prior to reaching Laguna Lake, with Area B being service at Stage 1, followed Service Area B at Stage 2. Table 7.

Hence, in Stage 1, Cupang STP will service sub-catchments A, B and C while Tunasan STP will service sub- catchments E and F. In Stage 2, conveyance will extend its service coverage to sub-catchment D to cover the whole of Muntinlupa, see Figure 8 for the revised conveyance service strategy. Figure 8. Revised Conveyance Service Strategy 2.1.6 Pollutant Loads Pollutant sampling was undertaken at a number of outfalls which have been mapped as shown in Figure 9 and described in Table 8. Influent characterization was undertaken and sewage was found to be generally of low strength in terms of BOD, COD and TSS and low to medium strength in terms of nutrient. 31 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report SP4 SP5 SP6 SP3 Figure 9.

Sto Nino St. X (nr. local vegetable stand) 33 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 2.1.7 Sewage Treatment Plant Technology Options Four process treatment technology options were shortlisted in the Feasibility Study to wit; 1) Activated Sludge Process (ASP), 2) Sequencing Batch Reactor (SBR), 3) Membrane Bioreactor (MBR) and 4) Moving Bed Bioreactor (MBBR). Treatment technologies were evaluated based on compact footprint, upgradability, odour generation, process robustness, standardization, ease in operation and maintenance and cost. Although SBR appeared to be more impressive, all technologies were found to be feasible. Table 9 presents the summary of comparison of the sewage treatment processes. Indicative arrangement or plant layout for each of the treatment options were shown in Figure 10-13. Table 9. Comparison of Sewage Treatment Processes Treatment Process Remarks Activated Sludge Process The design of the ASP consists of an aeration tank (or (ASP) bioreactor) and a clarifier. The same approach was adopted for SBR with the exception that a selector zone has been included for improved settling sludge and a lower Food to Microorganism (F:M) ratio must be used due to the intermittent process operation. ASP designs may also include selector zones. Figure 11 shows an indicative arrangement for ASP Membrane Bio Reactor (MBR) MBR combines the conventional activated sludge process but substitutes the clarifiers with membrane separation, which utilizes membrane filters to filter out solids and some of the pathogens in a much smaller tank than the ASP settlement tanks. The design approach for the MBR is the same as ASP’s, with the exception that a sludge retention time was used to fit the membrane supplier’s specifications. Figure 12 shows an indicative arrangement for MBR Sequencing Batch Reactor Retention time in the reactor is 24 hours. Aeration time and (SBR) sedimentation time can be set according to quantity and quality of influent. The process can also conduct digestion, denitrification and removal of biological phosphorus, which makes it ready for future strengthenng of water quality regulations on nitrogen, and phosphorus removal. The process has smaller size requirements. Management and operation is easy; requires little manpower and automatic operation is possible. Figure 13 shows an indicative arrangement for SBR Moving Bed Biofilm Reactor MBBR is based on specially designed plastic biofilm carriers (MBBR) or biocarriers that are suspended and in continuous movement within a tank or reactor. The MBBR process has the advantage that nitrification is not expected to occur in the same tanks as BOD removal. Nitrification is not likely because the bacteria grow on the carriers such that the nitrifying 34 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Treatment Process Remarks bacteria are shielded from dissolved oxygen by the organics oxidizing bacteria. The lack of access to oxygen by nitrifying bacteria means that nitrification can not occur concurrently with BOD oxidation in the MBBR option. This in effect reduces the installed aeration requirement. There is also no requirement for an unaerated zone for denitrification in MBBR. However, additional zones will be required if the plant must be upgraded for future nutrient removal. Figure 14 shows an indicative arrangement for MBBR Since the project will be bidded out using a “design and build” scheme, the selected process design is not final at this stage. However, MAYNILAD, shall issue design guidelines and principles that would include the following principles:  Design should be based on well-proven technologies, at minimum operating costs.  Safety should be provided in all aspects of the STP operation, with access of service units for maintenance purposes, and emergency operating procedures in an event of failure or an emergency  Design should meet all relevant Philippine Standards and international safety standards including but not limited to the Effluent Standards of DENR, Occupational Safety and Health Code, National Structural Code of the Philippines, Philippine Electrical Code, National Plumbing Code, etc.  The STP shall utilize a centralized control system such as MCC, PLC, and SCADA for ease in operation and monitoring  Odor and noise levels at theSTP should be maintained within allowable range  The STP should be suitably designed and constructed taking into consideration the environmental impacts and mitigating measures, site conditions, flood levels in the area, site area constraints, geologic hazards, among others. 35 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Figure 10.

Indicative Arrangement for MBBR 37 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 2.1.8 Sludge Management Alternatives Sludge management is considered as the quantities of sludge that will be likely to be significant regardless of the system characteristics. It aims to stabilize sludge, reduce pathogens and reduce water content. The sludge will be treated through sludge thickening methods that includes gravity sludge thickening, flotation sludge thickening or centrifugal thickening. Sludge digestion processes are divided into anaerobic sludge digestion and aerobic sludge digestion. Normally, the anaerobic sludge digestion process is adopted in facilities that handle large quantities of sludge. Anaerobic sludge digestion entails biologically decomposing the organic matter in sludge in an anoxic environment. When sludge is left in a sludge digestion tank for around 20 days, the organic matter in the sludge is gasified and the sludge is reduced in quantity to around 40~60%. Following digestion, the sludge undergoes sedimentation and is separated into supernatant (separated liquid) that includes soluble organic matter, digestion gas and stable digested sludge. Sludge dewatering will be carried out with the objective of removing the water content from sludge, thereby, reducing its volume and making it more amenable to treatment and disposal. Mechanical dewatering methods that are being considered include the centrifugal dewatering machine, belt press filter, and multi-disc dewatering machine. The dewatered solids will be transported offsite for stabilization. Disposal site of sludge will be in the lahar area in Barangay Telabanca, Concepcion, Tarlac where it is processed as compost and utilized as soil conditioner. The sludge processing facility of F.G. Agro Industrial Corporation holds an approved Environmental Compliance Certificate (ECC) from the DENR- EMB-Region 3. The same facility has been utilized by subprojects under the Manila Second Sewerage Project (MSSP) and Manila Third Sewerage Project. (MTSP). 2.2 Project Development Plan Currently, wastewater is collected, conveyed and discharged into rivers and creeks through street drainage lines with outfalls alongside the rivers and creeks. A combined sewer collection system will be applied by the project because of very congested areas in the service area in Muntinlupa City and also due to the huge cost and construction impact in these areas. Flows will be conveyed via streams mainly towards creek interceptors’ locations, where the dry weather flow will be diverted to a main trunkline acting as the conveyance. This trunkline generally runs along the road. Flows will be ultimately conveyed to the proposed treatment facility prior to reaching Laguna Lake. The system will be provided with overflow structures to prevent excess flows to the STP during heavy downpour. The sewerage system will consist of interceptors, manhole pumps and a STP. Table 10 outlines the project components. 38 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Table 10.

Interceptor(Gravity Main) Diameter(ｍｍ） >850mm Length（ｍ） 4,345 As the project will be bidded under a “design and build” scheme, the final specifications may be subject to some changes. The following describes an overview of the project components and general performance specifications of the project. 2.2.1 STP Capacity and Loading The total capacity of the Tunasan STP is 20 MLD for Stage 1. During Stage 2, Tunasan STP capacity will be upgraded to another 20 MLD and extend its service coverage to cover the whole of Muntinlupa. The STP shall be designed to accept the full flow to treatment during peak flow duration without overflowing. Below are the design parameters required for the plant:  Average dry weather flow (ADWF), m3/day - 46,000  Peak factor (p.f.) - 1.5  Peak flow duration - 3 hrs  Full Flow to Treatment (m3/day) - 1.5ADWF+GWI* * GWI – Ground Water Infiltration ADWF is defined as the average daily flow to the treatment plant during dry seasons. It is the sum of the wastewater entering the system or the wastewater flow (WW) plus the non- rainfall dependent groundwater infiltration (GWI). Hence, ADWF is used to refer to the ultimate sizing of treatment facilities. Wastewater flows is the sum of all sanitary flows entering the system, such as domestic, industrial and commercial flows. Wet Weather Flows (WWF) which is defined as the flows under wet weather conditions is not considered in the design or sizing of STP. Increased dilution during wet weather events significantly lowers the risks of discharging flows to the environment. Thus, minimizing the need to treat WWFs. However, it is important to note that even if the system is not sized to accommodate WWF, here will be enough capacity to handle some amount of rainfall and runoff occurring during the dry and wet months. This is due to a peak factor selection of 1.5 and the assumption of sewers running at 75% full. A pollutant peaking factor (varies in each parameter) will have to be adopted to account for the possible industrial flow. These pollutant peaking factors were based on available domestic and industrial water quality data of similar catchment characteristics, such as that of Valenzuela 39 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report catchment. The pollutant loadings indicated in Table 11 are the raw wastewater characteristics to be adopted in the design of the STP during Stage 1 (domestic, commercial and industrial flows) and Stage 2 (domestic flows only). Table 11. Raw Wastewater Characteristics for Stage 1 and Stage 2 Flows Parameter Pollutant Peaking Adopted Design Values (mh/L) Factor Stage 2 Stage 1 BOD5 3.0 91 273 COD 3.0 156 468 TSS 7.0 25 175 TP 1.3 6 8 TN 2.0 35 70 NO3 2.0 1 2 O&G 1.3 4 5 NH4 1.3 39 51 The effluent from the STP should meet the Effluent Standards for Class C water (Table 12). The BOD value of 273mg/l in the design criteria is higher than the actual raw wastewater taken from sampling results. This higher BOD value will be considered in consideration of future plans for a separate system. Table 12. Effluent Standards Parameter Unit Maximum Value (Class C) a COD mg/L 100 b BOD mg/L 50 c TSS mg/L 50 c Oil/grease mg/L 5 c Total coliform MPN per 100ml 1,000 Nitrate as NO3-N mg/L 10 Phosphate mg/L 1 pH 6.0 – 9.0 Notes: a – COD level above 468mg/l at the influent, the plant should have the capability of 85% removal efficiency b – BOD level above 273 mg/l at the influent, the plant should have the capability of 90% removal efficiency c – parameters above influent, the plant should not exceed the DENR Effluent Standard (DAO 35). The STP shall be designed to treat incoming wastewater from the system. It will be provided with preliminary screens, bar racks, preliminary grit and oil and grease removal system to remove inert and other floating solids and debris that may have entered the sewer lines. To accommodate sewage peak flows and shock loadings, methods such as flow equalization shall 40 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report be provided. The plant shall also have the capability to address removal of nutrients and a disinfection system to eliminate pathogenic microorganisms in the effluent prior to discharge. 2.2.2 Description of Project Phases The major phases of the project are the pre-construction, construction, operation, and abandonment phases. 2.2.2.1 Pre-Construction Phase This phase consists of the project planning and activities relating to securing the necessary permits and clearances prior to project construction. The acquisition of the project site also forms part of this phase. The acquisition of the project site also forms part of this phase. 2.2.2.2 Construction Phase The construction of the project can be divided into two phases: the construction of the treatment facility and the construction of the interception and conveyance system. These are separate items and differ in locations but both need to be phased together so that when sewage is conveyed through the network of pipelines to the STP facility for treatment, treated sewage will be discharged through an effluent outfall to a selected discharged point. For the interception and conveyance system, the pipes or sewer lines will run mostly along roads, therefore traffic management issues and plans for mitigation (e.g., road closures, detours, etc.) will be discussed and agreed upon with the local municipal officers concerned, prior to commencing construction. Just as roads require detours during pipe laying, installation of creek interceptor weirs require bypass systems for diverting the creek flows to clear the work area when installing the weir. Any interference expected from this construction should also be discussed with concerned local officers, before work is commenced. Consequently, a detailed design will then be carried out for the more practical option. Tender documents will be prepared based from the detailed design. These documents will be sent to Maynilad accredited contractors for tendering. The pipelines, sewers and pump stations will be installed and SCADA integration will be set-up. For the treatment facility, upon acquisition of land, STP construction will most likely be procured as a Design and Build contract. Timeframe is largely dependent on the contractor’s approach; 2.2.2.3 Operation Phase As soon as the target start-up date has been determined by Maynilad, the STP operations such as the collection, conveyance, and treatment of wastewater will commence. The STP will operate with consideration of applicable/related environmental laws and regulations that need to be complied with. Operations and maintenance of the project will be managed by the Maynilad. 41 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 2.2.2.4 Abandonment Phase The lifespan of an STP is estimated at 60-80 years while the conveyance and interceptor works are estimated at 50-70 years assuming proper operations and maintenance are observed. During the abandonment phase, in case of business closure, possible demolition or transfer of the facility or due to force majeure, necessary rehabilitation measures will be implemented by Maynilad. All structures such as conveyance and STP components will be decommissioned. An abandonment plan will be developed and will be implemented once a decision to abandon the project has been made. 2.3 Project Duration and Schedule The project implementation will be constructed in stages. Stage 1 will include construction of the 20-MLD STP and pipeline and appurtenances (creek interceptors, weirs and pump stations). Although timetable will be dependent on Maynilad arrangements, the goal is to accomplish Stage 1 completion by 2016. Stage 2 will then include another 20-MLD STP and laying the remaining lengths of pipes and construction of respective appurtenances. Assuming proper operations and maintenance are observed, conveyance system components can exceed 70 years, while the STP facility, with a number of upgrades, can operate well in excess of 60 years. 2.4 Project Cost The proposed project will have an estimated cost of Php 12,918,180.00 including the cost of land, civil, mechanical, electrical, and other works. 42 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 3 Analysis of Key Environmental Impacts 3.1 Physical Resources 3.1.1.1 Land Use Catchment Muntinlupa City has a total land area of 4,670 ha. Based on the Comprehensive Land Use Plan (CLUP), 46.04% of the city is residential, 6.00% commercial, 6.83% industrial, 1.67% institutional, 1.37% agricultural, and 38.09% open space. Industrial establishments in Muntinlupa are located densely in the northern portion of the city and near Laguna Lake (see Figure 14). Brgy Sucat and Brgy Cupang host the most number of industries in the city. Among the industries present in Muntinlupa are the 600- megawatt Power Station of the National Power Corporation and Zilog Electronics in Brgy. Sucat; Concepcion Industries in BrgyBul i; Uratex and Amkor, Inc in Brgy Cupang; Nestle and Sharp in Brgy Alabang, and Pepsi Cola, Inc in Brgy Tunasan. Informal settlements are present throughout Muntinlupa. Most lie along river easements, banks and shorelines. This is expected as, in most cases, no sanitation reticulation is available for these areas and disposal of wastes into streams is convenient. As such, informal settlements have considerable effects on the bodies of water as they directly contribute significant untreated biological load. A map of informal settlements in Muntinlupa is shown in Figure 15. 43 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Figure 14.

Location of Informal Settlements in Muntinlupa LEGEND Municipal Boundary Wastewater Catchment Boundary Rivers / Creeks Informal Settlements 45 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report STP Site: The proposed STP will be built in a property covering a consolidated land area of 8,333 sqm parcel of land located east of Buendia Street, within Bo. Tunasan, Muntinlupa City, Metro Manila. The land consists of various lots owned by different individuals. It is situated some 65 meters north from the road going to the Muntinlupa Sports Complex, 215 meters north from the Buendia and Arandia Street junction, 700 meters north of the corner of Arandia Street and Rodriguez Jr. Street and 1,300 meters northeast from the corner of the National Highway and Rodriguez Jr. Street. Buendia Street, the main access road to the site, is 5 meters wide and cemented.. The STP site is approximately centered by geographic coordinates 14031’54.39” north latitude and 121000’28.88” east longitude. The project site consists of various lots owned by different individuals. It is situated some 65 meters north from the road going to the Muntinlupa Sports Complex, 215 meters north from the Buendia and Arandia Street junction, 700 meters north of the corner of Arandia Street and Rodriguez Jr. Street and 1,300 meters northeast from the corner of the National Highway and Rodriguez Jr. Street. Buendia Street, the main access road to the site, is 5 to 8 meters wide and cemented. The property is partly surrounded with residential houses of middle income families as well as low income families particularly on the other side of the Buendia Street. Generally, the streets in the neighborhood are designed to accommodate light to heavy vehicular and pedestrian traffic loads. The terrain of the lot is flat with portions of lowered elevations from the road as shown in Photo No. 1. Photo 1. Southern part of Project Site 46 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Photo 2. View along Buendia St. Photo 2. A view inside the proj site with the Photo 3. Frontage along Buendia St. Muntinlupa Science High School on the east 3.1.1.2 Geology, Topography and Pedology Muntinlupa is typically underlain by Alluvium (Holocene). This underlying rock resulted from river deposition of sediment as rivers would flow into Laguna Lake. Hydrogeological properties of this formation are generally retentive of groundwater since cohesive fines form part of the alluvium. Muntinlupa topography is hilly to moderately rolling in the western inland portion, while areas near the lake shore are moderately flat. Gradients in Muntinlupa range from 1 to 10% with 69% of the total land area, including Barangay Putatan, having gradients from 0 to 2.5 %. Sloping hills, with maximum elevations of 60 meters, occupy the western to southwestern portion of the city. Flooding is usually encountered in the lakeshore area. The proposed STP sites is flat and open area. Whilst no development has been done of the proposed site, vacant lot, with dense grass vegetation, which may have been backfilled. Access roads where conveyance pipes will be laid are paved concrete roads. 3.1.1.3 Terrestial Biota The proposed STP site is commonly grasses, agricultural crops and some tree species such as neem tree (Azadirachta indica), Ipil-ipil (Leucaena leucocephala), raintree (Samanea saman) and camachile (Pithecellobium dulce). These trees are not considered as rare or endangered species. Likewise, there are no exotic species of flora and fauna which will be affected 3.1.1.4 Seismicity Based on historical data, there are five (5) potential seismic source zones consisting of four (4) active faults and one subduction zone identified to be the locus of major earthquakes that have significantly impacted the metropolis in the past. These are the Marikina Valley Fault System (MVFS), the Philippine Fault Zone (PFZ), the Lubang Fault, the Casiguran Fault, and the Manila Trench. Inquiry with Phivolcs was made regarding the geologic hazard that may affect the site of the proposed STP. The most compelling earthquake generator to the site is the West Valley Fault 47 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report of the MVFS, which is the nearest active fault in the area. The STP site is located approximately 59 meters southeast and 61 meters northwest of the nearest segment of the West Valley Fault (Annex F). 3.1.1.5 Geologic Hazards Ground Rupture Ground rupture can be defined as the breaking and movement of the ground along an active fault trace that may result to vertical or horizontal movement of the ground or a combination of these two types of movement. The VFS, particularly its southeast segments can have the greatest impact to the proposed project due to its proximity to the site as shown in Figure 16a and 16b. Paleoseismic studies conducted by Nelson et.al shows that there are at least four (4) large surface-rupturing earthquakes that have occurred on the northeastern splay of the WVF since the last 1500 years. It was estimated that a recurrence interval of 200 to 400 years for magnitude 6 to 7 earthquakes was manifested along this fault. The project has moderate to high vulnerability to this hazard since the trace of the WVFS is located approximately 59 meters southest and 61 meters northwest of the proposed site. Philvocs recommended a buffer zone against ground rupture hazard to be at least 5 meters on both sides of the mapped fault trace or from the edge of the deformation zone This hazard should be considered in the design of the structures. Ground Shaking Ground shaking is the trembling or jerking motion produced by an earthquake. Generally, the areas prone to this hazard are those underlain by thick, unconsolidated and water-saturated soil. In general, the catchment area has moderate to high susceptibility to ground shaking. Liquefaction Liquefaction is a process involving the transformation of loose, cohesion less, and water- saturated layers of soil from a solid to liquid state. One of the most obvious effects of liquefaction is differential settlement, where some portions of the soil mass underlying the foundation settle more than the other parts, thus, causing damage to the structures on the surface. The proposed project site of the STP in Muntinlupa is underlain by thick alluvial soils, which is susceptible to liquefaction hazard. Big magnitude earthquake caused liquefaction effect particularly in the eastern part of 8 Barangays, along the shore of Laguna Lake. Flood and Landslide Unusually heavy rainfall can lead to vast amounts of water draining into the water table. As more and more of the river's tributary streams join the river, this effect is amplified until the amount of water reaches a critical level; the banks or the natural flood plain cannot hold such a volume and it spills over thus causes flooding. Flood often occurs at lower reaches of a river in 48 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report areas of habitation, causing extensive damage. Moreover, huge amounts of rainfall can also cause the land to become soft and this can make the land move and cause a landslide. Based on the geohazard map developed by DENR-MGB, Muntinlupa City, where the project site will be situated, is highly susceptible to flooding with greater than 1 meter flood height (see Figure 17). The area is usually flooded for several hours during heavy rains, this include landforms of topographic lows and is also prone to flashfloods (DENR-MGB). These hazards should be considered in the design of the STP facility. Figure 17a. A shows the tectonic setting of the Marikina Valley Fault System. B shows the right-lateral strike-slip Marikina Valley Fault System (enclosed in rectangle outline) and its trace east of Manila to Laguna de Bay (Nelson, A.R., et al., 2000) 49 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Figure 16.

Landslide and Flood Susceptibility Map of Muntinlupa Quadrangle Laguna, Cavite and Rizal Provinces, Philippines (MGB-DENR and ESSC) 3.2 Ecological Resources 3.2.1 Aquatic Resources Poor water quality and physical disturbance of the creeks and rivers in the area had led to low aquatic biodiversity values. 51 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 3.2.2 Terrestrial Resources The proposed STP site is commonly grasses, agricultural crops and some tree species such as neem tree (Azadirachta indica), Ipil-ipil (Leucaena leucocephala), raintree (Samanea saman) and camachile (Pithecellobium dulce). Also, these trees are not considered as rare or endangered species.The total land area of the site is approximately 8,333 square meters.. 3.3 Water 3.3.1 Hydrology and Flooding Collectively, Muntinlupa forms a part of the Pasig-Marikina-Laguna Lake Basins. The Muntinlupa hydrological catchment is shown in Figure 18. The hydrological catchment corresponding to this study area is the sum of six sub-catchments named after the local rivers. The natural outlet of these rivers is Laguna Lake. The total land area of the hydrological catchment is approximately 4,750 ha. The hydrological catchment has a natural extension in San Pedro, Laguna and part of the storm water in this area may drain into the river boundary between Muntinlupa and San Pedro. Six sub-catchments form the Muntinlupa wastewater catchment, based on the topography of the inclusive river basins. These sub-catchments are: • Buli (750 ha) • Pasong Diablo (1,400 ha) • Bayanan (400 ha) • Poblacion (1,100 ha) • Tunasan (500 ha) • San Pedro (600 ha) The eastern boundary of the catchment is Laguna Lake while Daanghari forms the western boundary. South of the catchment is bounded by San Pedro River, which forms the boundary between Muntinlupa and San Pedro, Laguna. The northern portion of the catchment is bounded by the Municipal boundary of Taguig. Muntinlupa is situated in an alluvial plain developed from sediment deposit caused by river overflow. The inland portion is hilly to moderately rolling while the areas near Laguna Lake are generally flat. The elevation ranges from 0 to 60 m. There are also a number of rivers and creeks that cross the town and ultimately drain onto the lake. In addition to this, the conversion of Muntinlupa from a municipality into a city in 1995 has brought development of commercial establishments and large subdivisions and villages in the area some of which have poor drainage facilities. Muntinlupa is bounded by Laguna Lake to the east. It becomes a reservoir for floodwaters from Metro Manila and often experiences rising of water levels. This occurrence makes Muntinlupa vulnerable to interior flooding, especially during heavy rainfall or storms.Residents reveal that heavy rainfall often cause the nearby river that empties into Laguna Lake, to overflow. This is attributed to the small width of the river. Considering these informations, the following issues occur in Muntinlupa: 1) Sedimentation and blockage of drainage canals and pipes , 2) Susceptibility to tidal variations in Laguna Bay, 3) Poor drainage of subdivisions and 52 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report villages, 4) Regular inundation from river overflow. Flooding usually lasts for a few hours to three days. However, anecdotal evidence suggests that some areas can be submerged in excess of 2 to 3 weeks. Areas near the Laguna Bay periodically experience this. The flood map provided by the National Disaster Coordinating Council (NDCC) shows that almost half of the city is identified as flood prone area. However, the NDCC mapping is not intended to provide depths at a particular event return period. Over the last decade, considerable flooding in the area include Typhoon Ondoy (International Name: Ketsana, September 2009), which resulted in nearly 455mm of rainfall in a span of 24 hours. Water marks on buildings reveal that flooding in some portions of Muntinlupa reached extents of about 2 meters (UP National Hydraulic Research Center, 2009). After Ondoy, the area around Quezon/Ilaya Road near Laguna Lake was submerged for several weeks to in excess of one month. Based on the information on flood levels in the area, the STP should be designed taking into consideration the highest flood levels experienced in the area. In addition, the process to be employed in the STP should consider the saline water back flowing towards the creek and interceptors. The recorded or projected 2-meter maximum flooding in Tunasan STP site can be addressed through an acceptable engineering solution such as backfilling and raising of STP electro-mechanical devices/equipment and its control facilities above the highest recored flood level. In addition, the process to be employed in the STP should consider the saline water back flowing towards the creek and interceptors. 53 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Figure 18. Muntinlupa Hydrological Catchment 54 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 3.3.1.1 River and Catchment Flooding and Sea Level Changes Muntinlupa is situated in an alluvial plain developed from sediment deposit caused by river overflow. The inland portion is hilly to moderately rolling while the areas near Laguna Lake are generally flat. The elevation ranges from 0 to 60 m. There are also a number of rivers and creeks that cross the town and ultimately drain onto the lake.

Areas near the Laguna Bay periodically experience this. The flood map provided by the National Disaster Coordinating Council (NDCC) shows that almost half of the city is identified as flood prone area. However, the NDCC mapping is not intended to provide depths at a particular event return period (Figure 19). Over the last decade, considerable flooding in the study area include Typhoon Ondoy (International Name: Ketsana, September 2009), which resulted in nearly 455mm of rainfall in a span of 24 hours. Water marks on buildings reveal that flooding in some portions of Muntinlupa reached extents of about 2 meters (UP National Hydraulic Research Center, 2009). After Ondoy, the area around Quezon/Ilaya Road near Laguna Lake was submerged for several weeks to in excess of one month. Figure 19. Muntinlupa Typical Extent of Flood Map 55 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 3.3.2 Surface Water Quality Based on the Feasibility Study of the project, baseline surface water quality were established at different sampling locations. Water sampling was carried out by flow weighted composite sampling, taken at every hour from 5:00 am to 2:00 pm and 4:00 PM to 7:00 PM. Flow, together with dissolved oxygen (DO), electrical conductivity (EC), pH, turbidity and temperature were also measured on site. One grab sample taken at mid-day was collected for the analysis of Oil and Grease (O&G). The parameters analysed for all composite samples are:  Biological Oxygen Demand (BOD5)  Chemical Oxygen Demand (COD)  Total Suspended Solids (TSS)  Nitrate (NO3)  Oil & Grease  Total Coliform (TC)  Frcal Coliform (FC) Table 13 show the nominated sampling point locations for Tunasan, Muntinlupa. Average water quality sampling results are shown in Table 14. Results were compared with Revised Water Usage and Classification Standards (DAO 90-34), which outlines standards for bodies of water like the Laguna Lake that fall under Class C waters. Waterbodies classified as Class C are used for fishery water; for recreational purposes, like boating; and for industrial water supply, including manufacturing. Table 13.

High BOD concentrations in sampling sites may be due to presence of denser populations upstream of the sampling sites.  Total Suspended Solids The relatively low TSS reading for almost all the sampling points may indicate settling of the solids prior to sampling and the use of septic tanks in the catchment. For the parameter TSS, interpretation of results could not be made as the result needs to be compared with historical data to establish whether the measured levels are within the allowable 30 mg/L increase in TSS.  Oil and Grease Weak non-average and average O&G concentrations were observed in all sampling point locations and the average is below the prescribed O&G limit of 5 mg/L. This suggests that a specific O&G removal process at the STP is not required. Nitrate concentrations were within the set limits by DAO 90-34 for the four sampled sites. On the other hand, the four sampled sites exceeded limits for TC levels set by DAO 90-34. High BOD and TC levels are attributed to the fact that at the time of sampling, untreated domestic wastewater that contain high levels of coliform from human waste and other domestic activities 57 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report are released into waterways. 3.4 Air 3.4.1 Meteorology / Climatology The climate in the Metro Manila region belongs to the Type I classification of climates, which is characterized by a distinct dry and wet season. This type of climatic condition prevails in the western section of the Luzon Island. The wet season normally occurs from May to October while the rest of the year is relatively dry. 3.4.1.1 Cyclone Frequency The area is within a zone that can expect passage of about 5 tropical cyclones in every three years. Majority of the cyclones passing within the 50 km-radius from the bay occur in November. It is estimated that 47 percent of the annual rainfall is due to typhoons, 7 percent to the SW Monsoon (July to September), 7 percent to the Northeast (NE) Monsoon (February to May) and 39 percent to other weather systems. Compiled records of past flooding from DPWH and PAGASA between 1964 and 1990 indicate that at least 12 typhoons caused flooding within Metro Manila in conjunction with the Southwest Monsoon rains. Rainfall in the area can be attributed to the occurrence of the Southwest (SW) Monsoon, thunderstorm activities and tropical cyclones. In addition, the Philippines is geographically located in the most cyclone-prone area of the world. From 1948 to 1978, about 325 typhoons crossed the Philippine area of responsibility, with about 20 passing within the northern and southern limits of the metropolis. 3.4.1.2 Rainfall The maximum rain period occurs from June to September, which coincides with the southwest monsoon. During this period, the extremely moist air from the southwest monsoon crosses Manila Bay and enters Metro Manila with a considerable amount of rain. Regions of this climate type include those on the western part of the Islands of Luzon, Mindoro, Negros and Palawan. These areas are exposed to the southwest monsoon and get a fair share of the rainfall brought about by the tropical cyclones occurring especially during the maximum rain period. The coolest days are usually in December and January. Maximum rainfall in Muntinlupa usually occurs from the month of June to September. The average annual of rainfall is 1822.8 millimeters with a peak of 417.0 millimeters in August and a low 3.6 millimeters in February 3.4.1.3 Winds From October to May, prevailing winds in Muntinlupa City blow easterly at the rate of 9mph, while the rest of the months have winds blowing westerly. 58 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 3.4.1.4 Temperature The annual mean temperature reading for Muntinlupa is 27.92. The highest temperature occurs during the month of April and May (30o) while the lowest occurs during the months of December, January & Friday (26o). 3.4.2 Air Quality and Noise 3.4.2.1 Air Quality The air quality in the project area is primarily influenced by emissions from regular private and public vehicles passing through the road. In addition, resuspended dust particulates from exposed soil surface from ongoing development activities in the community contribute to an increase in total suspended particulates (TSP). Muntinlupa City is already experiencing a deterioration of its air quality. This may be attributed to the congestion of people and improperly maintained vehicles plying the major roads and highways. Local wind system is also an important factor in the quality of air in the project area. The thermal changes between day and night plays a major role in the diurnal wind systems. Thermal differences between the land and water surfaces are the main cause of coastal wind. Thus, the temperature affects the quality of air within the project site during daytime and nighttime, it being located near a coastal area. During daytime in the project site, the wind blows towards the land, known as the sea breeze, since the land heats up quickly under the influence of solar radiation while water surface remain cooler because the heat is dissipated over thick layers of water by turbulence and waves. Suffice it to say that the sea breeze brings fresh air into the land making the quality of air within the project site good. During nighttime the reverse happens. 3.4.2.2 Noise Similar to air quality, during the site visits, it was observed that daily activities of nearby residences as well as noise from passing of vehicles are the significant sources that could be identified in the proposed STP site. 3.5 Socio-Economic Conditions 3.5.1 Population The 2010 census data indicates a projected city population of 459,941, with an annual growth rate of 0.51% from the 2007 census population of 452,943. The city’s 2010 projected population density indicates 2,345 persons/sq.km. from the 2007 census population density of 11,459 persons/sq.km. 59 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Past census population data shown in Table 15 indicates a decreasing growth trend from a high of 7.54% in 1995 to a negative growth rate of 1.05% in 2000. The city’s 2000 census indicated a household population of 379,310. The city’s decelerating growth trends indicates that other areas in Metro Manila are becoming more attractive as settlement areas like adjacent cities: Las Pinas and Taguig and that the catchment area has already become congested. Table 15.

As compared with the national average, the city has a higher incidence of pulmonary tuberculosis and respiratory diseases as well as gastro-intestinal diseases, which suggests problems of pollution in the city. The leading cause of death (mortality) in the city is myocardial infarction, which is the same as the national average, see Table 17. Table 16. Leading Causes of Morbidity Causes 1. Bronchitis 2.

Cardiovascular Diseases including stroke Source: Muntinlupa City Health Office 2006 3.5.3 Economy Barangay Alabang, part of the second district of Muntinlupa, has undergone tremendous growth mainly due to a development boom in the late 1990s. The development of two large scale commercial real estate projects namely; the Filinvest Corporate City and Ayala Land's Madrigal Business Park, changed the landscape of Muntinlupa City from what was once vast fields of cow pasture in the late 1980s, into a supercity that houses new residential, business, industrial and commercial establishments. It was a transformation reminiscent of Makati City's development boom some 30 years prior. Some of the country's premier shopping centers, including the Alabang Town Center and the Festival Supermall, the towering Insular Life Towers, the Asian Hospital and Medical Center, and the Northgate Business District, which specializes in hosting information and technology industries, are important places of interest and landmarks of the city. Nightlife is still relatively staid compared to those of its neighbors, and younger residents often flock to other cities in Metro Manila, particularly Makati, Taguig, or Manila, during the weekend to enjoy the night out. This city has recently acquired the status "Most Competitive City" and the "Most Improved City" in the Philippines 61 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Photo 4. Skyline of Alabang, Muntinlupa Photo 5. Alabang area facing SLEX and Laguna de Bay 3.5.4 Health and Educational Facilities Several hospitals and medical facilities found in Muntinlupa City are listed below:  Alabang Medical Center  Alabang Medical Clinic  Asian Hospital & Medical Center  Babaran-Echavez Medical and Psychiatric Clinic  Beato Cauilan Hospital  Hillside General Hospital  KMI Specialists Hospital  MPI-Medical Center Muntinlupa  Muntinlupa Doctor’s Clinic  New Bilibid Prisons Hospital  Ospital ng Muntinlupa  Research Institute For Tropical Medicine  San Roque Medical Clinic Likewise, the city has good educational facilities which serve residences as well as migrants in the area. Table 18 presents the educational facilities in Muntinlupa City. Table 18.

Power service is provided to all types of consumers: residential, commercial and industry. Meralco distributes the power generated from various generating plants of the National Power Corporation and private firms that are located in various points in Luzon and connected to the power transmission grid. 3.5.6 Water Supply Households in Muntinlupa City depend on deep wells, water trucks and bottled water retailers for their water needs. However in 2010, the new water treatment plant owned and operated by Maynilad Water Services Inc became operational benefitting more than 220,000 households. The treatment plant source its water from Laguna Lake and water purification is done through microfiltration and reverse osmosis (ABS-CBN, 2010). 3.5.7 Transportation and Roads Muntinlupa City is 22 km south of Metro Manila, easily accessible from all points of Metro Manila through the national highway and South Luzon Expressway (SLEX). Likewise, Philippine National Railway has two stations in the city; these are Sucat and Alabang Stations. Muntinlupa city can also be accessed through the following roads: • Alabang-Zapote Road • Metro Manila Skyway • Daang Hari • C-6 Road 
 Locations and accessibility of STP potential sites are listed below. S1 is located along ML Quezon Ave. S2 is accessible through SLEX Sucat Exit to ML Quezon Ave and Meralco Road S3 can be accessed through SLEX Diversion Road near Espeleta Street S4 is accessible through the National Highway, which is parallel to SLEX S5 is accessible through pedestrian thoroughfares branching off from M.L. Quezon Road. S6 is located along ML Quezon Ave. 3.5.8 Drainage System Drainage facilities are often open canals which are often left uncovered and retain a fair volume of solid waste. These drainage facilities often drain into outfalls that terminate in natural water bodies and streams. It is along these water bodies wherein informal settlements are often located, leading to the clogging of the canals with solid wastes. 3.5.9 Sewerage System The city has no sewerage system or a centralized sewage treatment facility. Commercial and industrial plants are required to individually put-up their own wastewater treatment facility. Similarly, households are required to provide septic tanks as primary treatment of sewage 63 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report before it drains into the creeks and rivers. Majority of the households in the city use water- sealed toilet facilities with depository other than septic tank. 3.5.10 Solid Waste Management The city government of Muntinlupa is putting to good use trolleys, or railroad dump cars by turning them into rolling garbage bins to be used by residents near the tracks of PNR. The project is said to be first of its kind and part of the city’s aggressive effort to comply with the national government waste segregation. Under the program, collected wastes will be brought to a transfer station and then to the material recovery facilities in Alabang or Tunasan. 3.5.11 Culture and Heritage The catchment area is a highly urbanized zone and most of its land area has been disturbed several decades ago. There are no declared cultural or heritage sites within the catchment area. The possibility of any chance finds is remote. 4 Key Environmental Impacts and Mitigation The environmental assessment identified and screened a range of issues and impacts likely to arise from the execution of the project.

As much as possible, MAYNILAD will locate the conveyance system and related facilities at easements and ROW to limit the need for land acquisition. These ROW will be along easements of existing roads and banks of creeks. Coordination with the local government will be necessary to resolve any right-of-way issues during the construction phase. Clearances from the LGU and MMDA will be obtained to resolve any ROW issues. At the sites of the interceptor (gravity main), conversion manhole, force main pipe, and manhole pumps, residential households and commercial enterprises will be affected along the right-of-way. Temporary disruption of commercial and business operations may result during the construction of the conveyance system Another important consideration in the location of the conveyance system is the potential problems on traffic congestion due to the very limited capacity of the roads. During the construction of the conversion manholes, the capacity will be further limited and a need for traffic rerouting may be necessary in coordination with the local government unit. The narrow access roads, moderate to high density population and high intensity urban development in the area and along truck routes, and the limited space for the stockpiling of aggregates and parking of construction vehicles will constrain movement of vehicles/equipment as well as construction activities. During the construction phase, there is also a possibility of causing disturbance to establishments located along the roads where the conveyance system will be installed. The affected stakeholders will be informed in advance about any possible disturbance that may be caused by the project. Access will be maintained and provided to affected businesses/establishments and construction work plan will be developed and strictly implemented to minimize adverse impacts. Assessment on the number of affected establishments will also be made after the detailed survey and design of the conveyance system and its work program. 4.1.2 Impacts Relative to Process/Structural Design The important concern resulting from inadequate design is non-sustainability of the outcome that the proposed project is intended to achieve. Aside from the appropriate technical design parameters, the institutional, environmental management, and financial capability for operation, maintenance and repair should be a fundamental consideration in the design, including the approaches and practices to employ during the construction of the project and the procedures to follow during the operation and maintenance of the facility. The design of the facility should also consider the potential risks from climate change related disasters through the use of the projected rainfall change data, frequency of extreme events for NCR under medium and high range emission scenario, (i.e. 2020-2050),. A climate-resilient 67 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report design of the proposed facilty should be instituted to achieve environmentally sustainable result that the project is intended to attain.Another consideration during the design is the conservation of remaining trees within the proposed site of the STP and as much as possible conservation of these trees in the layout of the STP components. 4.1.3 Impacts During Construction As the proposed project will be located within a densely populated area, it is anticipated that the impacts of the construction phase will be moderate to significant. During construction, significant issues and impacts are dust generation, noise, vibration, wastes and sediment runoff, disposal of construction wastes and spoils to be disposed of, traffic and access blocking, accidental damages to nearby physical resources and private properties, accidental damages to existing utility lines resulting in disruption of services, disruptions to socio-economic activities, potential local flooding due to haphazard stockpiling and blocking of surface drainage flow, community health and safety hazards and occupational/workers health and safety hazards. During the construction phase, there is also a possibility of causing temporary income losses from establishments located along the roads where the conveyance system will be installed. The affected stakeholders will be informed in advance about any possible disturbance that may be caused by the project. 4.1.3.1 Traffic Activities during construction such as installation of conveyance system, road and river crossings, manholes and fitting of pipelines and sewers and the regular passing of heavy equipment will disrupt transportation and may cause traffic congeston in the area especially since the proposed sites are located near major thoroughfares. Traffic to and from the site may increase slightly due to construction of the STP. During pipe-laying, roads where pipes will be installed, traffic may likely be more congested. Any potential impact on the existing traffic conditions is expected to be significant but temporary. Delivery of construction materials should be done, as much as possible, during nighttime to prevent aggravating the existing traffic conditions in the area. The Contractor should provide adequate signage, including provisions for traffic rerouting if necessary, during the construction period. The Contractor shall coordinate with local police or barangay office on the issue of traffic management during the duration of the construction activities. 4.1.3.2 Air/Dust Pollution During the construction stage, the expected primary impact of the project on air quality is the increase in TSP concentrations near construction areas. During the construction phase of the project, the civil works and operations will entail digging and excavation of the soil that may cause some level of dust pollution in the air. Winds may carry soil particles to nearby areas, including the adjacent built-up areas. But the magnitude of this potential impact may be insignificant since the area to be disturbed is quite small. In addition, the increased number of vehicles moving in and around the project could result to an increase of pollutants coming from motor vehicles. 4.1.3.3 Noise and Vibration The expected noise sources during the construction and installation of the project components are the construction equipment such as jackhammers, bulldozers, graders, pay loaders, generators, compressors and heavy trucks. The expected noise levels at various 68 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report distances from this equipment are shown in Table 20. In work areas near communities, noise levels may exceed the DENR standards (Table 21). Along access roads, noise levels ranging from 65 to 80 dB(A) may be experienced in residential houses near the roadsides due to passage of vehicles and heavy equipment used in the project development. The noise levels may be lower if speed limits are imposed and vehicles are kept in good condition. If hauling of materials pass through communities, these activities should be limited to daytime only. Table 20.

Notes: Category of Area is as follows: AA - a section or contiguous area which require quietness such as area within 100 meters from school sites, nursery schools, hospitals, and special home for the aged. A - a section or contiguous area primarily used for residential purposes. B - a section or contiguous area primarily used as commercial area. C - a section primarily reserved as a light industrial area. D - a section primarily reserved as a heavy industrial area. Division of 24-hour period is as follows: Morning - 5:00 AM to 900 AM Daytime - 9:00 AM to 6:00 PM Evening - 6:00 PM to 10:00 PM Nighttime- 10:00 PM to 5:00 AM. 4.1.3.4 Impacts on Water Quality Silt Runoff from Construction The construction works will entail some excavation and will result to the exposure of the soil surface to the forces of weathering. During periods of rainfall, sediments may become eroded and cause surface runoff into the low-lying areas. The natural drainage channel of the runoff is the receiving creeks and drainage lines. Dusts and sediments during periods of rainfall may 69 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report contribute to runoff laden with silt. This could cause sedimentation and turbidity of receiving water bodies and clogging of drainage lines. In order to prevent the discharge of surface runoff into the drainage system and creeks, restoration of affected sections of the road is necessary. Domestic Wastes from Workers’ Camp Another potential source of water pollution during the construction phase is the generation of domestic sewage from the construction camps which include among others, office quarters, sleeping quarters, and toilet facilities. This is particularly significant during the construction of the STP where a greater number of workers will be involved. If wastewater is disposed untreated, the domestic wastewater could lead to the contamination of surface water and lead to the spread of water-borne diseases. Therefore, appropriate waste management measures should be instituted during the construction phase to maintain sanitation at the construction site. Potential Spill and Leakage of Oil Potential spill and leakage of fuel, petroleum products, lubricants, solvents, and other pollutants related to vehicle and equipment fuelling, maintenance, and cleaning may cause water pollution problems. The following mitigation measures for reducing such risks are proposed: (i) all vehicles and equipment that regularly enter and leave the construction sites will be fuelled off-site; (ii) Vehicle and equipment wash areas will be properly identified by signs and located away from drainage facilities and watercourses. These will be paved with concrete or asphalt to contain runoff. All vehicles and equipment that regularly enter and leave the construction sites will be cleaned offsite; and (iii) Storage of construction materials will be away from the creek and retention areas will be provided in order to contain accidental spills of such toxic, hazardous, and harmful construction materials as acidic substances, oil and petroleum products, and asphalt materials. 4.1.3.5 Generation of Construction Wastes Solid wastes generated during this phase will consist of construction spoils such as cement bags, discarded wood frames, workers’ wastes, etc. and vegetation spoils from clearing, and excavation. The excavation works of the STP will also generate overburden soil. This requires the pre-identification of the disposal site for construction planning purposes. In addition, the expected volume of the materials to be transported offsite would result to the frequent movement of haulers to and from the STP sites. Construction waste management plan will be prepared and will be made part of the project contract to be implemented by the general contractor. The plan should be able to address waste segregation and encourage the re-use, recycling and recovery of wastes. The contractor should implement proper disposal of construction spoils to designated waste disposal site. Wastes not disposed immediately will be temporarily located in a safe and secluded area at the site while awaiting transport and disposal. Waste management plan will be developed, subject to review and approval, before the start of any activity in the project site (Q1 of 2015). 70 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 4.1.3.6 Physical/Cultural/Heritage Sites There are no declared historical sites within the catchment area and the possibility of any chance finds is unlikely. The area has experienced urbanization and development for several decades. 4.1.3.7 Community Hazards due to Open Excavations and other Construction Activities To prevent accidents during construction, barricades and steel plate covers will be provided in open excavations during non-working time. Warning signs shall also be posted in the area. 4.1.3.8 Occupational Hazards During the construction phase, the construction activities could result to hazards on the safety of workers. The contractor will be required to implement a Construction Health and Safety Plan that will include the requirement on wearing of safety gadgets, posting of safety signages, and provision of sufficient lighting in dark areas of the construction site. 4.1.3.9 Inconvenience to Nearby Community due to Muddy Vehicles Leaving the Project Site The community in the immediate vicinity of the construction site will be inconvenienced by the muddy vehicles leaving the long muddy trails at the project site. This will be mitigated through the provision of a vehicle cleaning/washing facility at the exit of the construction site. This will include the use of a high pressure water hose to wash/clean the vehicles from mud. 4.1.3.10 Potential Increase of HIV Infections and Spread in Construction Camps Provision of HIV prevention information education campaign (IEC) and measures. 4.1.3.11 Peace and Order Issues on peace and order may be encountered because of the presence of construction workers who are not from the locality. 4.1.4 Impacts During Operation 4.1.4.1 Impact of Hydrology and Flooding The development of the proposed conveyance system and STP may have an impact on the flow regimes of the sub-catchment basins in Muntinlupa. Currently, flooding is experienced in the vicinity during storm events. The flows coming from the western section of the Muntinlupa catchment area naturally flows towards the downstream section of Laguna Lake. Flows will be conveyed via streams mainly 71 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report towards creek interceptors’ locations, where the dry weather flow will be diverted to a main trunkline acting as the conveyance. This trunkline generally runs along the road. Flows will be ultimately conveyed to the proposed treatment facility prior to reaching Laguna Lake. Although specific sites have not been chosen for stream crossings, in general, stream crossings may potentially induce erosion, sedimentation and scouring of the river banks. Once installed, stream crossings may potentially disrupt stream continuity, cause clogging or ponding in the stream, induce stream scouring and erosion, contribute unnatural riverbed materials and change water flow velocity (Biodrawversity, 2005). Nonetheless, if designed appropriately, the stream crossing can prevent bank erosion, provide good access to cross rivers/streams during flood events and contribute to improving aquatic habitat through promoting stream continuity (DOEP, 2000; Stratford District, n.d.). The installation of interceptor weirs will affect water flow along creeks as it will be used to capture wastewater from various areas around Muntinlupa. The flow of water downstream of the interceptor weirs will potentially decrease or cause the creek to dry up as a result of this. During the operation phase of the project, pumping stations are predicted to aid in preventing floods as these draw in wastewater from various points around Muntinlupa. The STP facility will have an impact on water flow in streams to which treated wastewater will be discharged to as it may increase or decrease water flow, depending on STP design. Optimum discharge volumes will be determined and will consider this information in the design of the STP facility to achieve environmentally-sustainable flows within the receiving water way. 4.1.4.2 Design of Climate-Resilient STP Structure Taking into consideration the likely impacts of climate change, with reference to the report on Climate Change in the Philippines by Pagasa, 2011, seasonal rainfall change in NCR (Metro Manila including Muntinlupa City), there is a substantial spatial difference in the projected changes in rainfall in 2020 and 2050. There is a reduction in rainfall during the summer season March, April, May (MAM) making the usually dry season drier. And during the southwest monsoon, June, July, August (JJA), and the September, October, November (SON) seasons, rainfall increases, making this seasons still wetter in NCR and thus with likelihood of both droughts and floods in the project site (see Table 22). The design and construction of the STP and its foundation structure should consider potential progressive erosion along the banks of the river bounding the STP site that would result to loss of surcharge and reduction in bearing capacity. Concrete retaining walls to serve as dike may be installed along the banks. The project design should also consider the shallow water table since excavations may prove to be difficult and costly. Retaining walls, sheet piling, driven piles, surface and subsurface drains, and other flood control measures may be necessary to prevent damage to the STP structures and equipment. The final elevation of the STP shall consider the highest flood levels to ensure that its operations, equipment and other appurtenances are not affected during flood events. Furthermore, the control room with all the electronic devices needs to be elevated higher than the predicted flood level to ensure proper operation in the event of an unforeseen flood events. 72 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report During flood conditions, access to the STP can be addressed using with a rubber boat. In extreme case of severe flooding, Maynilad has the capability to respond to natural disasters because of the Company’s adherence to its Emergency Preparedness and Response Program. Table 22. Seasonal Rainfall Change (in %) in 2020 and 2050 under Medium and High Range Emission Scenarios in Provinces in NCR Observed Baseline (1971- Change in 2020 (2006- Change in 2050 (2036- 2000) 2035) 2065) Medium DJF MAM JJA SON DJF MAM JJA SON DJF MAM JJA SON Range NCR Metro 107.5 198.5 1170.2 758.7 -12.8 -33.3 8.5 00 -17.3 -38.5 21.3 3.7 Manila High DJF MAM JJA SON DJF MAM JJA SON DJF MAM JJA SON Range Metro 107.5 198.5 1170.2 758.7 -53.2 -17.3 6.8 -19.1 -30.7 -26.8 -0.4 -2.6 Manila i.e. in Metro Manila, the projected values in 2020 is; DJF rainfall= (107.5mm+107.5(-12.8%)mm) = (107.5-13.8)mm = 93.7mm 4.1.4.3 Impacts of Solid Waste and Screening Wastes Screenings and solid waste shall be generated from the operation of the interceptors and preliminary treatment system. The screening wastes shall be collected daily from the interceptors and manholes to prevent the wastes from damaging STP equipment and pumps. The current inadequacy of solid waste management in the area and the presence of floating garbage at the creeks indicate potential problems for the STP. Coordination with the Local Government Unit (LGU) relative to the implementation of the solid waste segregation and collection will be important to avoid generation of large volumes of solid waste at interceptor boxes. 4.1.4.4 Odor The treatment and biodegradation of biological wastes, in general, generates odor compounds that may cause nuisance to adjacent residential communities. Screens, equalization tanks, and sludge digester during operation are all potential sources of offensive odors that can produce adverse environmental impacts on the adjacent communities. Remedial measures such as the provision of odor control systems will be instituted by MAYNILAD to prevent such occurrence. Other measures like planting of buffer strips of vegetation also helps in preventing odor from affecting adjacent communities. 4.1.4.5 Air Quality and Noise During the operation of the STP, no significant air quality hazard is foreseen since the equipment that will be used in the plants will work on electric power. However, the use of diesel power generators during power outage will emit various air pollutants such as suspended particulates, SO2, CO and Nox. Other possible source of air pollution is leakage from chlorine 73 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report gas (a noxious gas) used for disinfection of treated water. MAYNILAD shall minimize the generation of smoke, dust, vapors and noxious fumes from the operation of power generator by only using equipment that is in good condition and well maintained at all times. Noise generated in STP operation comes from operation of pumps and usually generate low frequency noise that is contained within the plant. The STP will be designed such that noise will be minimized. Mufflers may be fitted to gas and diesel-powerd equipment to minimized noise generation. Working Environment Measurement (WEM) that includes noise level and air quality monitoring within the facility will be conducted by MAYNILAD periodically. 4.1.4.6 Effluent and Sludge Disposal Process and structural designs may cause impacts of mild magnitude. These impacts can be successfully mitigated by application of sound engineering design principles to adequately accommodate the volumetric flow rate and organic load. The effluent should be able to meet the Effluent Standards for Class C waters as prescribed by DENR Administrative Order No. 35. Sludge generated at the STP will be managed through a sludge digester and dewatering system, the treated sludge will then be collected by FG Agro Industrial Development Corporation for conversion into organic fertilizer. Maynilad commissions the services of FG Agro Industrial Development Corporation, an accredited sludge waste hauler of Maynilad, that hauls and handles sludges generated by Maynilad STPs for processing into organic fertilizer for sugarcane and other similar crops farmland using the drying and composting process. FG Agro was granted an Environmental Compliance Certificate by the DENR for their drying and composting facilities at Bgy. Telebanca, Concepcion, Tarlac (see Annex D). The said drying and composting facility has a capacity of eleven thousand (11,000) cubic meters per year in an area of twenty five thousand four hundred thirty seven (25,437) square meters with geographical coordinates of 15017’10.7” North Latitude and 120037’35.2” East Longitude. 4.1.4.7 Generation of Hazardous Wastes Hazardous wastes such as empty chemical containers, analytical wastes from the laboratory, used oil from the generator set, and busted lamps will be generated when the project becomes operational. These hazardous wastes shall be collected separately from the regular solid waste of the facility. A DENR-recognized treatment, storage, and disposal (TSD) facility shall be commissioned by MAYNILAD to collect and properly treat the hazardous wastes in accordance with the requirements of Republic Act 6969 (Toxic, Hazardous, and Nuclear Waste Control Act). 4.1.5 Positive Impacts and Benefits Collectively, the proposed project will bring about qualitative improvement in the sanitation and health of communities, in particular those living near the water bodies. The living and health conditions will improve and the overall attractiveness of Muntinlupa City is expected to progress in the long-term. Water quality of streams/creeks/rivers are also expected to improve 74 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report with the reduction in pollution load. MAYNILAD will conduct regular monitoring of the effluent to ensure compliance with the Effluent Standards of the DENR. Other indirect benefits of the proposed project are increase in property values because of improvement in sewerage infrastructure, improvement of tourism potential of the area, potential return of fishing activities with improved water quality, and provision of employment opportunities. 75 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 5 Environmental Management and Monitoring Plan The mitigating measures to address adverse environmental impacts consist of activities and plans that are presented in Table 23. The Environmental Management Plan (EMP) and Environmental Monitoring Plan (EMoP) are developed for the design, tendering, construction and operational phases of the project. The bidding documents for the project shall include the implementation of the EMP. The EMP includes measures such as:  implementation of treatment processes based on environmental soundness,  specifying the construction occupational health and safety plan in the bidding documents of contractors,  preventing loss of vegetation,  climate-resilient measures in the design,  traffic management,  solid waste and sludge management,  effluent disposal in accordance with the standards,  siltation prevention of the waterways  management of domestic wastewater generation from temporary facilities  quality construction supervision and environmental monitoring by MAYNILAD,  observance of a grievance redress mechanism and prompt action/resolution of lodged grievances,  Full implementation of MAYNILAD’s Corporate Social Responsibility policies, and  Implementation of MAYNILAD’s Safety Code consistent with IFC-World Bank’s Environmental, Health, and Safety Policy. As a follow-up to the environmental assessment, an environmental monitoring program has been designed with the objective of monitoring the changes in key environmental elements so that any long-term adverse impact cause by the project can be predicted. Some of the monitoring targets include monitoring of unit operations and processes, beneficiaries, water quality of streams/creeks/river within muntinlupa sub-catchment 1, and effluent quality. 76 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Table 23.

The project site is a vacant field, raw and unused hence vegetation present in situ is mostly weeds and some coconut trees and not endangered terrestrial fauna. 5.1.2 Climate-Resilient Measures A climate –proof measures will be designed for the project based on the following: 1) highest reported flood experienced by the residents during the Typhoon Ondoy wherein 2 m. flood occurred at the site of the proposed STP, 2) likely impacts of climate change, with reference to the report on Climate Change in the Philippines by Pagasa, 2011, seasonal rainfall change in NCR (Metro Manila including Muntinlupa City), where there is a substantial spatial difference in the projected changes in rainfall in 2020 and 2050. Reduction in rainfall during the summer season March, April, May (MAM) making the usually dry season drier. And during the southwest monsoon, June, July, August (JJA), and the September, October, November (SON) seasons, rainfall increases, making this seasons still wetter in NCR and thus with likelihood of both droughts and floods in the project site, see Table 23., 3) storm water run-off will be considered in the design of the interceptors system. The final elevation of the STP shall consider the residents reported highest flood levels and the risks of the projected rainfall data based on climate change report to ensure that its operations, equipment and other appurtenances are not affected during flood events. The storm water runoff will also be considered in the design of the interceptor system and planting of more trees and vegetation as part of the site’s landscaping. During flood conditions, access to the STP can be addressed using with a rubber boat. In extreme case of severe flooding, Maynilad has the capability to respond to natural disasters because of the Company’s adherence to its Emergency Preparedness and Response Program. 5.2 Mitigating Measures During Construction 5.2.1 Traffic Management The frequent movement of construction vehicles hauling materials to and from the project site might hamper the flow of traffic along M.L. Quezon St. This is particularly significant considering that some sections of the street are being used as parking area of residents or terminal of tricycles. In order to avoid causing traffic along the street, the delivery vehicles will be advised to conduct hauling during off-peak hours where vehicle and pedestrian movement along the street is not significant. In addition, security personnel will be assigned at the gate of the property to assist in the movement of vehicles going to and from the site. 84 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report In order to control the potential traffic problems caused by the construction of sewer network and the STP, prolonged side street parking shall not be allowed. Traffic rerouting scheme shall be developed in coordination with the LGU to ensure smooth flow of vehicles. The traffic management plan shall be designed once the location of the conveyance system and the design of the project are finalized. The traffic plan should be approved by the LGU. In addition, appropriate signages informing the public about the traffic rerouting plan and schedule of project construction should be posted in strategic areas. Traffic management plan must be available, subject to review and approval, before the start of construction (Q1 of 2015). 5.2.2 Control of Dust and Air Pollution Air pollutants such as dust, SOx, NOx, and particulates will be generated during dry and windy conditions. This can be prevented and minimized by regular watering/sprinkling of areas prone to dust emission. The following mitigation measures are proposed:  During clear and windy day, the construction waste or materials should be sprayed with water or covered to prevent dust emission in the surroundings.  The waste management plan must include prompt removal of waste, ensuring that the hauling vehicles are not overloaded and are properly covered to prevent waste/dusts from being released along the way.  The site construction gate should be cleaned regularly to prevent migration of soil and dust offsite. The mobile monitoring stations will be placed downwind from the work areas based on the current and forecasted wind direction as indicated in the weather forecast 5.2.3 Control of Water Pollution Sanitary wastes and domestic wastes generated by construction workers may affect hygiene and sanitation in the surrounding environment and cause issues such as presence of fetid odors and development of diseases. The construction phase will require numerous workers at the site. The contractor will have to make sure that domestic wastes are cleaned-up promptly from the site. Portable toilets should be provided at the construction site. No random dumping of domestic waste should be allowed by the contractor to guarantee good hygiene and health conditions for the construction workers. During the construction period, natural surface runoff into the drainage system will be disrupted by the construction of temporary works such as barriers, trenches, deviation channels mounting around the stockpiles of materials. Furthermore, good housekeeping will be maintained at all times during the construction process. 5.2.4 Protection of Riverbanks alongside STP Site To ensure that loose soil from river banks will not contribute to deterioration of the river due to siltation and obstruction of normal flow of river, riverbank protection measures such as riprapping shall be undertaken to reinforce the side of the river adjacent to the STP site. The shoring works on the riverbanks should be designed in such as way that this will not alter the configuration of the river or produce siltation due to soil erosion. It is important that the final 85 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report alignment of the riverbanks will maintain the original width of the river and will not encroach or reduce the width of the river through reclamation. 5.2.5 Control of Noise Nuisance The construction works will be located in a central urban district and any heavy noise generating activities will be prohibited at night, unless, a special authorization has been obtained at the local barangay level or from the local government unit. Mufflers may be fitted to gas and diesel-powered equipment to minimize noise generation. 5.2.6 Management of Construction Wastes Construction wastes consists mainly of excavated spoils produced during construction of gravity mains, conversion manholes, and STP components. The transportation and handling of construction waste will require frequent movement of hauling vehicles and could affect local traffic. In addition, dust in the air or mud on the ground may be generated from spill of these materials. In order to minimize these impacts, the excavated soil may be used for backfilling and restoration of affected areas. Construction waste management plan will be developed and will be included in the project contract for adoption and compliance by the general contractor. The plan will address the proper segregation, re-use, recycling and recovery of wastes. Waste management plan will be developed, subject to review and approval, before the start of any activity in the project site (Q1 of 2015). 5.2.7 Community Health and Safety Community health and safety during the construction of the proposed project will be considered. Any potential risks to community health and safety such as risks from uncontrolled access to construction sites, exposure to waterborne, water-washed, and water-associated diseases resulting from excavation and water impoundments and exposure to increased traffic due to movement of construction materials will be addressed through the implementation of a community health and safety procedures through the project’s general contractor. Excavation works at roads may result to accidents and hazards for the community. To prevent accidents during construction, barricades and steel plate covers will be provided in open excavations during non-working time. Concrete barriers may be used for the separation of traffic and protection of workers in high-speed areas or in vulnerable situations where the lateral clearance between workers and moving traffic would be insufficient for adequate safety. Concrete barriers may also be used for protection for deep excavation. Warning signs shall also be posted in the area. The contractor will be required to strictly implement MAYNILAD’s Safety Code and IFC- World Bank’s Environmental, Health, and Safety Guidelines. 5.2.8 Occupational Health and Safety During the construction phase, the construction activities could result to hazards on the safety of workers. The contractor will be required to implement a Construction Health and 86 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Safety Plan, which will be made part of the contract that will include the requirement on wearing of Personal Protective Equipments (PPEs), posting of safety signages, and provision of sufficient lighting in dark areas of the construction site. An Emergency Action Plan should also embody the necessary steps that should be undertaken by the contractor when an accident occurs. Medical assistance as well as first aid kit shall always be available at the site. These plans are all included in the Maynilad Safety Code (Annex E). 5.3 Mitigating Measures During Operation 5.3.1 Management of Collected Solid Waste and Screenings The interceptor boxes with screens shall be designed to collect the solid wastes and silt. At the STP, the screening of solids may be affected using bar racks or mechanical bar screens. Fine screens may remove inert materials. Grit removal may be accomplished after bar screens and before the equalization tank in order to protect mechanical equipment from abrasion and accelerated wear. The system will remove sand, gravel or any other heavy non-putrescible materials in the sewage. The solid waste, screenings, and grits shall be 1) collected by the garbage collector of the local government and 2) hauled and disposed to designated landfill. The LGU and service provider provides the landfill/disposal site. In coordination with the LGU, MAYNILAD will assist in the strengthening of the solid waste management program of the locality through information and education campaign programs aimed at instituting behavioral changes among the residents on solid waste segregation and management. The IEC program will be implemented starting at the early stage of project planning and shall continue up to the operational phase. The program aims to reduce the volume of solid waste that is uncollected and end up in the waterways in Pasay City. 5.3.2 Release of Effluent to Laguna Lake The STP is estimated to release about 5.55 cum/sec of treated wastewater into the Laguna Lake during dry weather flow based on calculations. During the design phase, the most appropriate location of the discharge outfall will be studied thoroughly to ensure that the release of effluent into the lake will not result to flooding at the downstream areas. During the operational phase, MAYNILAD shall coordinate closely with the MMDA/LGU to monitor the average upstream water elevation at the pumping station. This will allow Maynilad to determine the appropriate regulation and timing of wastewater releases from the STP. 5.3.3 Odor Control Odor emission from the STP will be managed through an odor control system that will be integrated in the design of the facility. Mitigation measures will also include the planting of green 87 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report belt at the site boundary and the preservation of the existing large trees at the periphery, which can serve as protective buffer. 5.3.4 Management of Sludge FG Agro Industrial Development Corporation, is the third party hauler and treater of the treated sludge generated at Maynilad STPs. FG Agro was granted an Environmental Compliance Certificate by the DENR for their drying and composting facilities at Bgy. Telebanca, Concepcion, Tarlac (see attached ECC). The said drying and composting facility has a capacity of eleven thousand (11,000) cubic meters per year in an area of twenty five thousand four hundred thirty seven (25,437) square meters with geographical coordinates of 15017’10.7” North Latitude and 120037’35.2” East Longitude. Sludge generated at the STP will be managed through a sludge digester and dewatering system. The treated sludge from the sewage treatment plant will be collected and hauled by FG Agro and will be brought to their drying and composting facilities in Concepcion, Tarlac. It will be dumped on the drying beds for 20 to 30 days for sun and air-drying under dry weather condition. Then, the dried sludge will be gathered from the drying beds for composting. Composting process is done by spraying the dried sludge with Indigeneous Microorganism (IMO) /Effective Microorganism (EM) for fast decomposition and mixing with Carbonized Rice Hull (CRH) to increase water retention. Composting period is within 30-45 days, the resulting composted product, which is called “Biosolids”, will be bagged for land application to sugarcane and similar crops farm land in lahar-laden areas. Biosolids application may either be through an injector type applicator or manual surface spreading. Figure 21 describes the process flow diagram of drying and composting for sludge management. 88 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Figure 20. Process Flow of FG Agro Industrial Development Corporation 5.3.5 Air Pollution Control To control any adverse effect on the air quality in the vicinity caused by the generator set, regular maintenance shall be undertaken on the said equipment. Regular testing shall be undertaken and Permit to Operate from DENR shall be secured. 5.3.6 Traffic Management During the STP’s operational phase, adequate parking spaces are available by the site for its workers and guests. Trained security personnel will be assigned to direct the flow of vehicles coming in and out of the area. Vehicles hauling sludge from the site will also observe the implementation of truck ban. 5.3.7 Physical and Cultural Resources According to the site assessment, there are no historical and heritage sites and structures that may be affected by the project. If chance finds are encountered during excavation, the National Museum shall be informed immediately to determine the importance of the discovery and whether or not the construction works can carry on. 89 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Measures shall also be undertaken to include physical protection, overfill protection, and tank integrity. Access to the STP site and its facilities will be restricted by implementing security measures such as perimeter fencing of adequate height and of suitable material. 5.4 Mitigating Measures During Abandonment Phase The lifespan of an STP is estimated at 60-80 years while the conveyance and interceptor works are estimated at 50-70 years assuming proper operations and maintenance are observed. During the decommissioning phase, necessary rehabilitation measures will be implemented by Maynilad. All structures such as conveyance and STP components will be decommissioned. An abandonment plan will be prepared and it will be implemented once a decision to abandon the project has been made. The plan will describe measures to be taken in case of business closure, possible demolition or transfer of the facility or due to force majeure. 5.5 Environmental Monitoring Plan Environmental monitoring reports shall be submitted by Maynilad to LBP and WB during the pre-construction up to the construction phase of the project. Compliance Monitoring Reports (CMRs) shall also be submitted to DENR on a semi-annual basis following the requirements of DENR Administrative Order 2003-30. The monitoring reports shall be prepared by the PCO of MAYNILAD. During the construction phase, the PCO shall make sure that the contractor submits its Environmental Compliance Report to MAYNILAD and that the PCO shall verify the findings presented in the report of the contractor. The monitoring reports should also contain the results of implementation of the environment, health, and safety program of the project. In addition, an annual Third Party Audit (TPA) of the environmental performance of the project shall be commissioned by MAYNILAD. The result of the TPA shall be submitted to LBP and WB. Table 24 presents environmental monitoring plan. 90 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Table 24.

These plans will provide forums for updating stakeholders periodically on project progress and the implementation of mitigation measures. These plans will be incorporated into an IEC plan. The Information, Education and Communication Plan of MAYNILAD aim to foster active participation by the communities and generate support for the project. It also aims to inform the people about the details of the project. Information should be provided as needed so that the people will decide, not only on the basis of the economic benefits that they may derive from the project, but also after taking into consideration the environmental risks that the project may entail. Full disclosure of information enables a community to consider the options open to them and to make informed decisions. The IEC framework shall consist of advisories and IEC programs designed to inform the LGU and adjoining establishments regarding activities that will affect smooth operation of the project. Table 25 below outlines the proposed IEC program of the project during the pre- construction/construction and operational phases. Table 25.

John Emmanuel B. Martinez as the Grievance Officer of the project who can be contacted at 981-3484. Engr. Martinez shall coordinate with the responsible units/departments about any possible complaints lodged on the project. The Grievance Redress Mechanism is divided into complaints lodged during the construction and operation of the project. During the construction phase, an affected person or complainant can approach or call the Maynilad or contractor to raise his/her complaints or concerns. Complaints will be immediately relayed to the responsible party for prompt action. If the complaint is not acted on promptly, or if the affected person is not satisfied with the resolution undertaken, he/she can then avail of the formal mechanism, as follows: Step 1: Affected person lodges the complaint. Step 2: The General Contractor (during construction) and the Sewerage Operations Department (during operation) will document and register received complaints. Step 3: A meeting will be called between the affected person and the General Contractor (during construction) and the Sewerage Operations Department (during operation). The affected person will be immediately informed if the grievance is within, or outside, the purview of the mechanism. If the scope is outside, the affected person will be referred to the proper institution and/or proper mechanism for the complaint. If the complaint is within the scope of the project, the resolution of the complaint shall be discussed during the meeting. Investigation will be immediately scheduled for proper resolution of the complaint. The contractor/Sewerage Operations Department will immediately provide the most suitable interim measure to reduce the magnitude of the impact and to start work on the final measure not later than 5 days from the day of the discussion meeting. Step 4: If the affected person is satisfied with the resolution of the complaint, MAYNILAD shall obtain a written confirmation of satisfaction from the affected person. Step 5: For at least a week after closure of grievance, MAYNILAD through the Grievance Officer shall monitor the effectiveness of the resolution. Step 6: In the event that the issue/impact persists, the affected person can lodge an appeal to the Barangay. The Barangay Chairman shall immediately record the appeal, contact the Grievance Officer and contractor of Maynilad, and call for a meeting to review the history of the grievance to discuss the immediate resolution of the issue. If the issue still persists despite the second action, the affected person can seek assistance from the City Government. 5.8 Institutional Plan for EMP Implementation During construction phase, the Contractor shall fully implement the mitigation and enhancement measures presented. In addition to the task of Maynilad or its duly authorized representative in supervising the construction of the proposed STP facilities, it shall ensure that the recommended measures as well as suggestions concerning environmental protection from 95 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report DENR/LLDA are followed and applied. The Terms of Reference (TOR) of the contractor shall stipulate compliance of the project with the requirements in the EMP and EMoP. The Maynilad shall closely coordinate with the Contractor to ensure that provisions in the environmental program are effectively implemented. Regular inspection of the working area shall be conducted focusing not only on technical aspect but also on environmental considerations. The implementation of the EMP and EMoP starting from the planning, design, construction, and operation shall be supervised by the Environmental Management Department of Maynilad. When the project is turned-over to the Operations Department during completion and commissioning, the facility shall designate a Pollution Control Officer (PCO) to assume the responsibilities related to environmental management of the project. All matters relating to pollution control should be the main concern of the PCO. The appointed PCO shall closely coordinate with the Environmental Management Department on matters relating to EMP and EMoP. Environmental monitoring reports shall be submitted by MAYNILAD to LBP and WB throughout the project cycle, beginning from the preparation of the bid documents and at the onset of the pre-construction phase. 96 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 6 Social Assessment The acquisition of large areas of land is needed for the physical component of the project. It is expected that environmental impacts, positive and/or negative, would arise because alterations will be made in the area. The project is also likely to induce irreversible social changes on the immediate community. The total land area to be acquired for the proposed STP covers 8,333 sq. meters. The properties being acquired for the proposed STP are owned by four (4) persons. They are relatives. The four (4) owners are as follow: Dominador Almendrala with area of 2,000 sq. meters; Fe Almendrala with area of 3,000 sq. meters; Pedro Aman with an area of 3,000 sq. meters; and Consuelo Casacop with an area of 333 sq. meters. The land acquisition of the four (4) lots is through a “willing seller -willing buyer” approach. Appraisal documents showed that the lots are free of encumbrances. The zonal value of the property as provided by the Bureau of Internal Revenue (BIR) on their official website is Php 2, 500 per sq. meter. While, the appraised value provided by the Maynilad accredited broker, Cuervo Valuers & Advisory Inc., is Php 1,220.63 per sq.m. Based from the same report, the average market value is Php 10,171,000.00 for the gross land area of 8, 333 sq. meters in the area. The appraisal of the properties was done on May 21, 2012 and offer to sell was submitted to Maynilad by seller’s broker on June 13, 2012. Contracts to Sell (CTS) and Deeds of Absolute Sale (DAS) with the sellers were already signed. The sellers have also signed Acknowledgment Receipts upon receiving the partial and full payment of their sold properties. At present, only Consuelo Casacop and Dominador Almendrala received full payment for the sale of their respective properties. The full payment for Pablo Aman will be released upon submission of documents necessary to complete the registration of the sale and the transfer of title of the land to Maynilad. While, the full payment for the sale of the lot owned by Fe Almendrala will be released upon completion of the transfer of the 15 PAPs to their relocation site, removal of any improvements / structures and submission of important certificates/documents for the complete transfer of title to Maynilad. Although the purchase of the land is through a “willing -seller-willing-buyer” method, there are fifteen (15) informal settlers (IS) residing at Fe Almendras property that will be affected by the project. They have to be relocated. Maynilad establishes the number of the Project Affected Persons (PAPs) and determined that fifteen informal settler households were covered by the entitlements as defined in the Resettlement Policy Framework (RSF). For the fifteen (15) informal settler households identified to be affected by the land acquisition, entitlements are as follows: a) The lot owner has provided a site for the relocation of the PAPs. The site is along Buendia Street and is just 40 meters away from the PAPs previously inhabited lot. The PAPs relocation site would cause no significant socio-economic disruptions or physical adjustments to the present activities of the PAPs owing to its proximity to the present land they occupy. The 15 families will be relocated together as a group and maintain the same neighborhood. 97 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report b) The relocation site is a land of 3,333 square meters, which belongs to the estate of the family of the sellers. The plan is to subdivide this land into parcels of lot of 32 sq. m each and sell them to the PAPs at a discounted price. There would be 47 parcels of lot in the relocation site that would be available for purchase. A portion of the land will be dedicated for the PAPs while the rest of the lots will be sold to other prospective buyers. Each PAP families will be allocated with 32 sq. m. of lot at a cost of Php 2,000/ sq. m. (present zonal value) or for a total cost of Php 64,000. This will be paid in an installment basis. The owner is also willing to sell more than one parcel to any PAP household willing to purchase more lots. c) The project-affected families will be allowed to use the lot for two (2) years rent-free before they start paying for the monthly amortization of the lot in the succeeding 10- year period. This is to direct the use of their resources in rebuilding their house/structures. The corresponding savings the PAPs can have for the given 2-year grace period/rent-free will be calculated as an additional entitlement of the owner for the PAPs. The annual cost associated with land lease/rental is normally ten percent (10%) of the selling price of the lot, thus the 32 sq. m lot, which costs Php 64,000, could have an annual rental of Php 6,400. This would translate in a 2-year rental cost of Php 12,800 or an equivalent monthly rental of Php 530. Each PAP families will save Php 12,800 amount as an entitlement for the 2-year grace period/rental-free given by the owner before the monthly amortization for the lot commence. Assuming they will not avail of the relocation site offered by the owner and just rent somewhere near the area, the 2-year rental for a house can be costly for them. The prevailing cost of house rental near the area is shown below. Prevailing cost of house rental near the area 15 sq. m., concrete, 1 bedroom 25 sq. m., concrete, 1 bedroom Type of house with small kitchen & toilet with small kitchen & toilet Monthly rental fee - Php 2,500 Php 3,500 After two (2) years - Php 60,000 Php 84,000 d) The PAP families will have the option to have an outright purchase or fully pay the same in a period of twelve (12) years (2-year rent-free + 10-year installment period) with no interest. Based on the CTS, Php 500 and Php 1,000 pesos will be the monthly amortizations for the 32 sq.m. and 64 sq.m. lots, respectively. The owner has offered the installment-based purchase to be interest free as an additional assistance/entitlement for the PAPs. Considering the net present value of the lot which is Php 64, 000 – if fully paid after 10 years, the lot would have a future value of Php 114,614.25 if a compounded annual interest of 6% (prevailing market interest) is included in the purchase. The interest, which amounts to Php 50,614.25, is offered by the owner as a discount to the cost of the land and is considered as part of the assistance to the PAP families. 98 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report e) On top of this, the owner will shoulder the associated cost of relocation, the capital gains, documentary stamps tax, development cost and all other costs associated with the preparation of individual titles for the lot for a total amount of Php 15,900.00. All in all, each PAP family will get the following assistance/discount from the lot owner for the ownership of a 32 sq. m. lot; Cost of the Transfer of Title `- Php 15,900 Free use of land for two (2) years - Php 16,000 Ten (10) years of interest free - Php 50,614 TOTAL - Php 82,514 These are all on top of the financial transfer assistance per household given by the lot owner to PAP families. f) Every PAP household received financial assistance last May 17, 2013 from the owner to facilitate their transfer. Edmon Naeg & Ramon Bontog, owners of 2-storey combined concrete & wood houses were given twenty-thousand pesos (Php 20, 000) each in consideration for their structures. While, Mark Aaron Ramos received five thousand pesos (Php 5,000) from the owner since his house is just shanty. The rest received ten thousand pesos (Php 10,000) each, as what they have recently agreed with the owner g) The lot owner would also allow them to salvage any materials from their houses. The transfer of their properties and salvage materials to the relocation site will be easy because it is just a walking distance from their present location. The owner will also assist them. h) All PAPs were properly informed as to the plan of the owner to sell the lot to Maynilad. They received Notice to vacate as early as November 07, 2012. They were given at least 90 days upon receipt of the notice to vacate the land they are occupying. However, after this 90-day period, the PAPs still remained in the owner’s land. They were requested by the owner to voluntarily remove their structures as soon as they received the agreed financial assistance 6.1 The Project Affected Persons 6.1.1 Displacement of 15 Informal Settlers Households Based on the survey conducted on March 2013 fifteen (15) informal settler (IS) households or a total of seventy (70) project affected persons will be displaced due to Maynilad acquisition of the Fe Almendras property needed for the construction of the Tunasan Sewage Treatment Plant. The 15 informal settlers were properly informed on the plan of the lot owners to sell the property. They were given notice to vacate the area as of November 2012. Each of the informal settlers were given financial assistance for their relocation and for the affected structures and other investment made on the land. 99 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Luz Almendrala, a relative of the property sellers, Fe Almendras, offered her idle land to the PAPs to be their relocation site. The lot is approximately 40 meters away from PAPs present location and is planted with vegetables, root crops and coconut tree. She is willing to sell the lot at a low price at an installment payment scheme. Payment period depends on how big the area they want to occupy. She is willing to give PAPs two (2) years grace period to enable them to rebuild their houses 6.1.1.1 Resettlement Status of Fifteen (15) Informal Settler Households The clearing operation started on December 10, 2013. One (1) IS household, the family of Edmon Naeg, signified not to transfer to the relocation site. They chose to dwell near their relative’s residence. However, he handover his allotted lot to his brother and will be the one to occupy his portion. The socio-economic profile of Naeg household appears he is capable of paying the monthly amortization (Php 500) of the lot and is economically favored than other IS households, owing to the regular remittances he receive from his wife working abroad. Also, his previous concrete dwelling implies that he is capable of building a decent house. Seven (7) of the 15 PAP households have already transferred and started to rebuild their homes on their soon-to-be-owned lots. Two (2) households are starting to put skeletal structures for their houses but are not yet transferring. The other four (4) households have not yet put up any structures but signified an interest to transfer. Table below shows the summary of the resettlement status. Generally, they signified contentment on their entitlement received. Maynilad interviewed some of the resettled PAPs during the Due Diligence on Jan. 01, 2014. Mrs. Letty Isturis and Ramon Bontog said that they are relieved by the idea of having a lot to call their own and start a new life free from fear of being ejected. The Barangay committed to provide backfills and electric post in the area. Some of the PAPs have already water connections. Maynilad committed to help other resettled families have water connection through its Muntinlupa Business Area.

Richard Isturis . 6.2 The Project Affected Structures 6.2.1 Loss of Houses of Informal Settlers House structures of the 15 IS are made up of wood, concrete and combination of both. Majority of these houses were built in a permanent structure. Based on the survey conducted on March 2013, all of these informal settlers were amenable to be displaced and be relocated. They were given financial assistance to compensate for the affected structures and other investment made on the land and for their relocation. 6.3 Other Potential Social Impacts 6.3.1 Noise and Air Pollution The expected noise sources during the construction and installation of the project components are the construction equipment such as jackhammers, bulldozers, graders, pay loaders, generators, compressors and heavy trucks. Along access roads, noise levels ranging from 65 to 80 dB(A) may be experienced in residential houses near the roadsides due to passage of vehicles and heavy equipment used in the project development. The noise levels may be lower if speed limits are imposed and vehicles are kept in good condition. If hauling of materials pass through communities, these activities should be limited to daytime only During the operation of the STP, no significant air quality hazard is foreseen since the equipment that will be used in the plants will work on electric power. However, the use of diesel power generators during power outage will emit various air pollutants such as suspended particulates, SO2, CO and Nox. Other possible source of air pollution is leakage from chlorine gas (a noxious gas) used for disinfection of treated water. Maynilad shall minimize the generation of smoke, dust, vapors and noxious fumes from the operation of power generator by only using equipment that is in good condition and well maintained at all times. 103 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Noise generated in STP operation comes from operation of pumps and usually generate low frequency noise that is contained within the plant. Working Environment Measurement (WEM) that includes noise level monitoring within the facility will be conducted by MAYNILAD 6.3.1 Odor Emission from the Sewage Treatment Plant Odor emission from the STP will be managed through an odor control system that will be integrated in the design of the facility. Mitigation measures will also include the planting of green belt at the site boundary and the preservation of the existing large trees at the periphery, which can serve as protective buffer. 104 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report 7 Bibliography Active Faults in the Philippines.

Business Area representatives were also present during the Public Consultation. Business Area representatives will be the ones to work closely with the community and ensure good reception of the project in the area. After the presentation, the public/community and leaders were encouraged to raise questions and issues concerning the project. The issues and concerns raised: a. Conveyance route b. Project schedule c. Sewer network d. Effluent water to be used for water distribution e. Residual chlorine f. Water quality g. Solid waste management h. Role of LGU in the project i. Tariff implications Proceedings of the Public Consultation Meeting Engr. Reynaldo C. Angeles, Head of Maynilad’s Wastewater Catchment Management, presented the proposed Muntinlupa-Tunasan STP project. He opened his presentation by showing the present condition of the Manila Bay. He further emphasized the benefits of the project to the community as well as to the major receiving bodies of water; the Manila Bay and Laguna Lake. He discussed the components of the plant, treatment processes and the catchment design. One of the relevant questions raised during the public consultation was regarding the locations of pipelaying for the conveyance system of the proposed STP. Mr. Franklin Tating, President of Park Homes Village HOA, asked if the conveyance will be laid in the different HOA subdivisions in Tunasan and will the project timeline consist of ROW acquisition in those areas. Michael Jay Fajardo, a Maynilad-WMD Officer, answered the question by presenting the scheme to be used in Muntinlupa South Catchment. Maynilad will be implementing a creek 112 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report interception (as discussed by Engr. Angeles in his presentation) and pipelaying will be implemented along Buendia S.t in Tunasan. Engr. Angeles added that the said scheme was chosen in accordance to the Feasibility Study (FS) conducted. Pipelaying will consume more time especially in acquiring Right of Way. The scheme will eliminate pipelaying in subdivisions and villages therefore avoiding inconvenience for both Maynilad and the HOA. Another question asked was about the roles and responsibilities of the LGU in the project. Mr. Pablo Aman, United Homeowners Association of Tunasan, asked the LGU role in this project. Engr. Angeles explained that the LGU will play a vital role especially in Solid Waste Management. Dumping of solid wastes are the main factor causing clogs in the drainages and rivers, he added. Maynilad’s mandate is to treat the wastewater but we cannot take out the fact that solid waste will still flow to the conveyance line. Maynilad will provide screens in the conveyance manholes and interceptor box. But once these screens will be obstructed with solid waste, wastewater flow to the STP will be lesser. The obstructed wastewater might be diverted to the nearest manhole and will cause flooding on the streets. For this reason, the proper management of solid waste is very important to the success of the project, Engr. Angeles emphasized. The meeting was adjourned at 11:30 AM. 113 | P a g e TUNASAN SEWERAGE SYSTEM PROJECT Environmental Assessment Report Photographs of the Public Consultation Photo 1.

(A) 2. Bring the vehicle to full stop before entering any through street, highway or railroad crossing. (B) 3. Check traffic to the left, then to the right, to see if there are vehicles crossing the street. Proceed only when traffic is clear. Do not rely on your having the right-of-way. (A) 4. Signal well in advance and proceed to the correct turning lane from a reasonable distance. Let approaching traffic clear first before making a left turn. (A) f. To avoid a sideswipe collision, the driver shall: 1. Slow down when being overtaken on left or right to make it easy for the other vehicle to pass. (Do not race the other vehicle.) (A) 2. Check your rear side mirror; make a signal and change lane only when it is safe to do so without disrupting the flow of traffic. (A) 3. Signal well in advance, slow down gradually and keep as close to the right or curb when making a right turn. (A) 31 4. Check the rear, signal intentions and wait for a break in traffic before pulling out of a curb or parking space. (A) g. To avoid head-on-sideswipe and angle collisions, the driver: 1. Shall not drive to the left side of the centerline of the highway in overtaking or passing another vehicle preceding in the same direction unless the left side is clearly visible and is free of incoming traffic.

After first aid is given, the injured or sick employee should be brought to the medical unit. General Instructions: 1. A first aid kit, which should be readily available at all, times. First aid kits must be properly maintained and inspected at frequent intervals by the foremen or others in charge. 2. Stop and think, Keep calm in all emergencies. If you are familiar with first aid methods, do not hesitate to take charge of the situation. Direct 114 the action of others and do everything in your power to preserve the life and comfort of the injured. If you are not familiar with first aid methods, ask someone. 3. In any case, except very minor injuries, lay the patient down in a comfortable position, examine for all injuries and see that a doctor is called for at once. Do not excite or frighten the patient- a word of encouragement is always helpful. 4. If alone, treat first for stoppage of breathing needing artificial respiration; second, severe bleeding; third, for internal poisoning; fourth, for open wounds; fifth, for burns; sixth, for fractures and dislocation. Other less serious injuries can be taken care of. 5. If patient is unconscious and is not breathing or if you are uncertain of his action, start artificial resuscitation at once. 6. Handle patient gently but firmly. 7. Loosen tight clothing at neck and waist. 8. Do not slip clothing over injured part. Rip it at the seams with knife or scissors. 9. If the patient is vomiting, turn his head to one side so he will no choke. 10. Patient should always be kept warm. 11. Never give unconscious person water or any liquids to drink. 12. Do not move an injured person unless absolutely necessary. Do not be in a hurry to transport the patient. Much harm may be done when jarring and shaking the patient. SHOCK OR FAINTING This condition is present in many cases of minor or major injury. Fainting is a mild form of shock. 1. Lay the patient flat on his back with his head low. 2. Keep the patient comfortably warm with blankets, robes, coats, etc. External heat, such as hot water bottles, hot pads, etc., should not be applied unless the covering appears to be inadequate or the patient complains of being cold. In applying heat to the body, great care must be exercised to prevent burning the patient. 3. Provide plenty of fresh air, 4. Have the patient inhale aromatic fumes from ammonia ampule. If patient is conscious, give him a glass of water or a hot drink (tea, coffee or water) as a stimulant. Administer frequently in small doses. (Inhalants must be carefully used. Do not hold too close to nose. Try them on yourself first. ) WOUNDS 1. Any break in the skin is a wound and is likely to become infected. All wounds, no matter how small, must receive first aid attention. A. Wounds Without Severe Bleeding: 1. Wash the wound with soap or water. 115 2. Dry it with cotton balls or let it dry. 3. Apply antiseptic solution, e.g. alcohol etc. 4. Cover it with sterile gauze compress and bandage. 5. Puncture wounds from nails, long sprinters, etc. should receive the immediate attention of a physician. 6. Do not disturb blood clots or scabs. 7. Do not remove foreign bodies, except small splinters from wounds. These maybe carefully remove from tweezers, the points of which have been scorched in a flame sterilized with antiseptic. B. Wounds With Severe Bleeding: 1. Secure medical aid at once. Apply direct pressure by using compress or bare hand. 2. Place patient in a lying position and elevate the injured part if possible, above the heart. 3. Apply pressure with fingers on arterial pressure points, if known. Apply digital pressure by pressuring the artery that supplies blood to the wounds. 4. Place large scales gauze compress over wound and bandage tightly in place. 5. As a last resort to check bleeding from an injured limb, a tourniquet may be applied close to the wound. There should be unbroken skin between the tourniquet and the wound. If the wound is near a joint, make the wrap at the nearest point above the joint. Attached a note on the victim’s body indicating the hour of tourniquet application. The tourniquet should not be released except by a physician who is prepared to control the hemorrhage and replace blood volume adequately. Improvised tourniquets should be made of flat material about two inches wide ( i.e., cravat bandage, stocking or a belt ). Do not use rope, wire, or sash cord: they may cause injuries to the underlying tissues and blood vessels. 6. Do not give stimulants in case of severe bleeding. Cold water may be given in small doses. INFECTED WOUNDS There is no first aid treatment for infection. A physician must always be consulted promptly. BURNS: 1. Do not break blisters. 2. Carefully cut away clothing from the burned area and apply sterile burnt solution or ointment. Never use iodine. 3. Cover lightly with several thickness of sterile gauze and bandage. Never use cotton for burns. 116 4. In all cases of chemical burns on the skin, thoroughly flush the burned area with plenty of clean water. Then treat as directed above. 5. For chemical burns to the eye, see section on Eye Injuries. 6. Creosote burns-when skin surfaces contact with creosoted poles, wash parts thoroughly with soap and hot water. Apply Isopropyl Alcohol (Creosote burn solution). Never use this solution in or near the eyes. INJURIES TO BONES Injuries to bones are sometimes difficult to detect. If a fracture or dislocation is suspected, treat as such. Falls or other accidents involving injury to the neck or back may result in very serious after-effects if the spinal cord is injured. Unless there is an imperative need to move an individual suspected of having a spinal cord injury to a zone of safety, the injured is best not moved or lifted, until medical aid is obtained. FRACTURES: 1. Avoid unnecessary handling of patient and injured part. (Great damage may be done by sharp edges of bone puncturing blood vessels and tissues). 2. Place the patient at rest in a comfortable position. Call a doctor at once. It is not necessary to splint broken bones unless the patient must be move. However, never move the patient until the broken bone is splinted. 3. When to splint; Cover the joints above and below the fractured member. Splints must be thoroughly padded and carefully applied. 4. In compound fractures where bone protrudes through skin, treat the wound first as directed under the section on WOUNDS. DISLOCATION: A bone out of position at a joint is called a dislocation. 1. Treat dislocation by the application of cold or hot compresses. 2. Secure medical aid promptly. It is always advisable to have a doctor to put the dislocated joint back in place. SPINAL CORD INJURIES Never lift an injured person or his head until he is sure he can move his legs or fingers. If the victim cannot move his legs, his back may be broken. In both cases, the spinal cord is injured. If the patient must be moved, proceed as follows: 117 BROKEN BACK In case of a broken back, fold a blanket lengthwise and place it beside the patient. Hold him at the shoulders and hips and gently roll the patient over into the blanket with the head turned to one side. One arm may be folded so as to lie beneath the patient’s head. By pulling at the shoulders and hips, the trunk is moved as a unit. The blankets should be lifted by grasping it at the level of the patient’s shoulders and knees. This permits the patient’s back to sag slightly downward on a stretcher or a similar support and must be transported in this position. Do not permit the patient to sit up. BROKEN NECK If a person with a broken neck must be moved, a board or shutter should be placed lengthwise beside the patient so that it is at least four (4) inches beyond the patient’s head. The board should be five (5) feet or more in length and at least (15) inches wide. The neck is steadied by holding the head between the two hands. One or more persons shall slide the patient onto the board so that he rests with his face upward, arms at side, head, trunk and extremities on the board. The body, head and neck are moved as one. Fold and secure the arms over the chest. Strap the patient to the board to prevent him from falling off during transportation. No pillow shall be placed under the head or neck. Under no circumstances shall the head be tilted forward or sideways. If the injured person is found lying face downward, the board shall be placed beside the patient in the same manner as described above. The head and neck are then steadied between the two hands while another person gently rolls the patient onto the board, holding the patient at the shoulders and hips so that he lies face up. The head and trunk must be turned at the same time. Although there may be no symptoms, if a broken back or neck is suspected, transport as if the back or neck were broken. When the victim is unconscious, handle him as though his neck is broken. POISONING: FOR NON-CORROSIVE POISONING (WITHOUT ACID CONTENT) 1. Dilute the poison with water. Let the victim drink as much water as he can. 2. Induce vomiting. 118 3. Administer antidote (anti-poison) or milk to neutralize the poison inside. 4. If breathing stops, give artificial respiration. FOR CORROSIVE POISONING (POISON WITH ACID CONTENT, E.G. MURIATIC ACID) 1. Dilute with water. Note: Don’t let the victim vomit. It can enhance further tissue damage. 2. Administer antidote: 1 part strong tea 1 part milk 2 parts charcoal POISON VINES-IVY, SUMAC, OAK, ETC.: Learn to identify these plants and avoid contact with them. 1. If portions of the skin are exposed, wash thoroughly several times with hot water and soap and then apply rubbing alcohol liberally. 2. If rash develops, wash again, apply rubbing alcohol and saturate with 5% solution of ferric chloride, calamine or other approved poison ivy lotion. Cover lightly with sterile gauze. 3. Always consult a doctor if the wound is severe. BRUISES, SPRAINS AND STRAINS 1. Bruises are not usually serious. However, other internal injuries should be suspected. Apply cold or hot applications which will reduce swelling and pain. 2. Sprains are injuries to joints. Place the patient at rest and elevate the injured limb. Cold applications will reduce pain and swelling. 3. Strains are injuries to muscles. Rest injured muscles. Cold application and gentle massage of the injured part will help ease the pain. If strain is in the abdominal region, rupture should be suspected and a doctor consulted. EYE INJURIES: All cases except the most trivial ones MUST BE ATTENDED BY A DOCTOR FOREIGN BODY IN THE AREA 1. Never probe or dig the eye for removal of embedded particles. If an object is floating on the surface, it may be brushed off with a clean cotton application or the corner of a sterile gauze compress. 119 2. Do not allow the patient to rub his eye. This will cause great irritation and do little good. 3. If the particle cannot be readily removed or if irritation continues, the eye should be flooded with a 10% solution of boric acid ointment. A couple of drops of clean olive oil or castor oil should then be applied. 4. Do not remove splinters from the eye. BURNS TO EYE In all cases of burns to the eye, the patient must be sent to a doctor. 1. Chemical burns-Never neutralizes chemical burns of the eye. It is too risky for a novice to attempt this. Thoroughly flush the eye with clean water, then drop olive oil, castor or boric acid ointment into the eye. 2. Electric flush burns or fire burns of the eye should be treated with clean olive oil, castor or boric acid ointment. Do not use water. 3. Cover eye with a soft gauze compress. Iodine must never be used in or near the eye. BITES Dog or Cat Bites 1. Wash the wound thoroughly with soap and water. (This is the only exception where the use of soap and water on a wound is permissible. ) This is done to eliminate the animal’s saliva. 2. Treat as any open wound. 3. Always consult a doctor. (If possible, identify the owner of the animal). INSECT BITES 1. Treat as an open wound. 2. Watch closely for the development of infection. SNAKE BITES If you work in a snake-infested area, insist on a special snake first aid packet for your use and familiarize yourself with the special instructions on the treatment of snakebites found in the packet. FIRST AID FOR NON-VENOMOUS SNAKE BITES: Treat as an ordinary wound. FIRST AID FOR VENOMOUS SNAKE BITES: 1. Immobilize the injured patient. 2. Apply a constricting band. 3. Make an incision on the bitten part. Note: Incision should be along the vein, not across the vein. 120 4. Suck the incised area to remove the venom. 5. Transport the victim to the hospital. GENERAL INSTRUCTIONS: 1. Don’t get excited. Keep quiet or don’t move to avoid increase in the circulation of the venom. 2. Don’t take a slug of whisky. 3. If bitten on a limb, let it hang down. Don’t do more harm to yourself than the bite would have done if you hadn’t treated it, particularly if you are not sure you have been bitten by a poisonous snake. Some have been so slash-happy with the knife, tied the lymph constrictor so tight, or left it on so long that infections, ulcers, gangrene and other complication result. 4. Sit where you are and carry out the first part of this treatment. 5. If you think you are bitten by a rattlesnake but can find no fang marks and have no pain or swelling within fifteen (15) minutes of the bite, you are probably mistaken in the identity of the snake or the snake injected very little venom. 6. Make no incisions but get to a doctor promptly. 7. Kill the snake, if possible, without undue excitement or exercise, to know whether it is really a poisonous snake. If practical, take the dead snake to your doctor so that he may know its size and identity. 8. Paint knife blade and fang marks with antiseptic. Make cross (x) incisions at the fang marks ¼ ″ long and 1/8 ″ to ¼ ″ deep. (Do not make incisions if the bite is on fingers, toes or over large visible veins). Squeeze air out of the cup and place over incisions. Steady gentle suction is better than strong suction. The cups hold on best if the skin is moistened with antiseptic (alcoholic beverages may be used but antiseptics from first aid bites are much preferred.) If the patient can be taken to a hospital within fifteen (15) minutes, don’t do anything-just get to the hospital and have someone call ahead so that they can be prepared and have anti venom ready. CONVULSIONS OR FITS: 1. Place the patient flat on his back and insert a padded stick between teeth to prevent the patient from biting tongue. 2. Do not restrict convulsion action but try to prevent the patient from inflicting self-injury, especially to the head. 3. After a convulsion, the patient must be kept warm and quiet. A doctor must be called. SUNSTROKE: Sunstroke is caused by prolonged exposure to the direct rays of the sun. Condition comes on rapidly. Face is flushed, skin is dry and hot and 121 breathing is heavy. A high fever is present. Treat this condition by reducing fever as quickly as possible by sponging head and the entire body with cold water. Never give patient stimulants (cool water may be given). Keep patient lying down with head and shoulders slightly elevated. Get medical help at once. Quick action is important. Do not use ordinary treatment for shock. HEAT EXHAUSTION: Heat exhaustion usually occurs in hot places where the circulation of air is not good. It is entirely different from sunstroke. It causes collapse from the effect of heat. The patient is very pale, skin is covered with clammy perspiration, pulse is weak and breathing is shallow. Treat by moving the patient to a cool place with good air circulation. Place the patient on his back with head low and then cover him with blankets or coats. If the patient is unconscious, give him aromatic spirit of ammonia dipped in a cotton ball as stimulant. Get medical aid at once and keep the patient quiet. Treat for shock. HEAD INJURIES Every head injury should have the attention of a doctor. Fractured skull or concussion should be suspected and treated for. 1. Lay the patient down. 2. Give no stimulants. 3. Keep the head slightly raised and apply cold compresses to forehead and back of neck and heat to the rest of the body. 4. Treat any wound if present. 5. Transport these cases very carefully. ARTIFICIAL RESUSCITATION: In case of accident involving electric shock, the following action shall be taken immediately: 1. Breaking the contact- the victim must be freed from contact with the live conductors as promptly as possible. Use a long dry stick or pole or another non-conductor. Interrupt the current supply if this can be done safely and quickly. 2. Begin rescue breathing (mouth to mouth to nose method) at the earliest possible second after the action under Item I has been taken. Remember: the brain has only 4 minutes to live without oxygen. 3. While rescue breathing is in progress, have someone examine the heartbeat of the injured by feeling the pulse on his wrist or on his neck, just at the side of the Adam’s apple. 4. (a) If the heart of the injured is still beating, rescue breathing should be continued uninterrupted until normal breathing of the injured is restored or rigor mortis has begun. This may be four 122 (4) to six (6) hours longer or place for care and treatment until after normal breathing has been restored. He may be lowered from the pole, but must not be otherwise moved. 5. If the heartbeat of the injured has stopped, the injured should be lowered as soon as possible and both the rescue breathing and the closed chest heart massage performed simultaneously. (a) As soon as possible, an ambulance should be called. Continue an uninterrupted artificial respiration and closed chest heart massage until normal breathing and normal heartbeats are restored. (b) If a second person is not available, the rescuer may interrupt massage every thirty (30) seconds to fill the chest two (2) or three (3) times (rescue breathing). Mouth to mouth ventilation and chest massage do not have to follow the same rhythm. (c) As soon as the ambulance arrives, the injured shall be taken to the nearest hospital that has facilities for cardiac treatment. During the trip to the hospital, artificial respiration and heart massage shall be continued in the ambulance. At the hospital, the injured shall be turned over to the attendants of the Medical Staff who must be immediately informed that the injured was a victim of electric shock and that his heartbeat has stopped. 6. Keep the injured warm at all times during treatment and during the trip to the hospital. 7. (a) These rules should be called to the attention of a doctor in attendance whose order is not in agreement, the doctor should be requested to assume full responsibility. (b) A doctor in attendance may give the injured an injection of adrenalin, render first aid treatment for surface wounds and burns and take such action as he may deem necessary. All the while, artificial respiration must never be used in cases of electric shock. The MWSI employee present who is senior in position shall be held responsible for complying with these instructions. In case of an accident involving a non-employee, he should not insist that these instructions are followed, but it shall be his duty to recommend and urge that the instructions be followed. CLOSED CHEST HEART MASSAGE: In an accident such as drowning, suffocation, gas poisoning, heart attack, overdose of drugs or electric shocks, one or two things can happen. Breathing may stop while the heart still beats or both breathing and heartbeat may stop. In either case, death is just a matter of minutes if no decisive and immediate action is taken. Rescue breathing and closed chest heart massage should be given immediately as the case may be. 123 The following actions should be taken immediately when the heartbeat of the victim has stopped: 1. Lay the victim on his back (supine position) on a firm or rigid surface. 2. Locate the breastbone by feeling the notch where the collarbones meet at the top end and the cartilage located in the middle of the breast below the ribs at the bottom. 3. Place the heel of the palm of one hand on the lower third of the breastbone and the other hand on top of the first. Palms should be parallel to and not touching the ribs. 4. Pressure is applied vertically downward and forcefully at least once per second. Pressure must be strong enough to move the breastbone 11/2 ″-2″ toward the spinal column. 5. At the end of each stroke, the hands are completely relaxed to permit full expansion of the chest. 6. Repeat operation continuously at one (1) second intervals until normal beating is restored. 7. If beating has been restored, the patient must be watched, and if natural beating stops, closed chest heart massage should be resumed at once. 8. While the closed chest massage is in progress, send for an ambulance. 9. The injured shall be taken to the nearest hospital. During the trip to the hospital., artificial respiration and closed chest heart massage shall be continued in the ambulance. MOUTH TO NOSE METHOD OF ARTIFICIAL RESPIRATION: 1. The victim should be laid on his back with his head tilted as far as possible so that his neck is extended. If there is a slope, placing the victim’s body with the head slightly downhill is advisable. 2. The operator closes the victim’s mouth by placing the palm of one hand on the victim’s jaw with continued pressure applied. 3. After taking a deep breath, the operator places his mouth completely over the victim’s nose with airtight contact. 4. The operator then breathes or blows into the victim’s nose forcefully for adults and gently for children. The victim’s chest should be watched and as soon as it rises, the blowing should be stopped and the operator’s mouth quickly removed from the nose of the victim, allowing him to inhale passively. 5. If the chest does not rise, the position of the head should be improved and the blowing done more forcefully. If the victim’s lungs are still not ventilated, his airways may be obstructed. He should be placed in a face down, head down position, his 124 tongue pulled forward and patted firmly on the back to dislodge any foreign object. 6. The cycle of inflation and exhalation should be repeated approximately 12 times per minute for infants and small children. The mouth to nose method is recommended for use on pole top resuscitation. MOUTH-TO-MOUTH ARTIFICIAL RESPIRATION (Rescue Breathing) Basic steps: a) Opening the airways b) Restoring breath Causes of Stoppage of Breathing: 1. Anatomical Obstruction- e.g. the tongue falls backward due to unconsciousness; tonsillitis. 2. Mechanical Obstruction- presence of foreign materials in the airway passage, e.g. choking, cave-in, electrocution. Proper Steps in Giving Artificial Respiration: 1. Check for unconsciousness (5 sec.) 2. If unconscious, tilt the head (5 sec.) While tilting, check the mouth for the presence of any obstruction like un-chewed food or any prosthesis. 3. Look, listen and feel for breathing in order to recognize respiratory arrest. (5 sec. ) Look- at the rise and fall of the chest Listen- for air escape during exhalation by placing your cheek near the victim’s nose Feel for the carotid pulse at the side of the Adam’s apple. 4. If the victim is not breathing, give full, slow breaths. 5. Check again for pulse and breathing. 6. If still not breathing, give one (1) per five (5) seconds until the victim has revived. Ratio: I blow per five seconds Normal respiration-16-20 respiration per minute POLE TOP RESUSCITATION: After a person has received an electric shock, it is very important that he receives the application of resuscitation immediately. The time elapsed between the electric shock and the application of resuscitation may make the difference between life and death. 125 The pole top method of resuscitation was developed with the sole purpose to cut down this elapsed time to give the victim a greater chance for survival. POLE TOP RESUSCITATION RESCUE BREATHING (MOUTH TO NOSE METHOD): Calling Alarm: 1. Anybody who sees the victim first should call the alarm. 2. He should call out the location of the victim and his name. 3. He should give out noticeable details as to the victim’s position. A. Going to the Rescue: 1. The man nearest the victim should immediately start to go to the rescue of the victim. 2. The rescuer should take all necessary precautions to prevent injury to himself. 3. He should have his rubber gloves on and must not rush to the scene of the accident without quickly planning a safe means of rescuing the victim as quickly as possible. B. Releasing the Victim from Contact: The rescuer, after reaching the victim, should immediately release the victim from all contact with live parts, taking caution not to make any body contact with the victim or the live parts except with rubber gloved hands. Administering Resuscitation: 1. The person who will administer artificial respiration takes a position on the pole a little higher than the victim. 2. The head of the victim is tilted backward, as far back as possible, in a face-up position. The rescuer’s rubber gloves should not be removed. 3. The operator closes the victim’s mouth by placing the palm of one hand on the victim’s jaw with continued pressure applied. 4. After taking deep breath, the operator places his mouth completely over the victim’s nose and blows forcefully. The victim’s chest should be watched and as soon as it rises, the blowing should be stopped and the operator’s mouth quickly removed from the nose of the victim, allowing him to exhale passively. 5. If the chest does not rise, the position of the head should be improved and the blowing done more forcefully. If the victim’s lungs are still not ventilated, his airway may be obstructed. He should be placed in a face down position, his tongue pulled forward and patted firmly on the back to dislodge any foreign object. 6. The cycle of inhalation and exhalation should be replaced 12 times per minute. 126 C. Rescuer’s Assistant: 1. Another man should go up to the pole to aid the rescuer. He should bring with him a hand line with a diameter of not less than ½ inch. 2. After reaching the victim, the second man shall immediately determine whether the heartbeat of the victim has stopped. He can do this by feeling the pulse at the victim’s wrist or at the neck alongside the Adam’s apple. Another check would be to open the victim'’ eyes. If the pupils of the eyes are dilated (wide open), it indicates that no blood is reaching the victim's brain. D. The following actions should be taken after the examination of the heartbeat of the victim: Heart Still Beating: 1. The rescue breathing shall be continued uninterruptedly until normal breathing is restored. 2. The second man shall look carefully for hazards and use additional protective rubber equipment as necessary to make certain that the lives of both rescuer and the victim are not endangered by live conductors. 3. He should remove the victim’s climbers to prevent possible injury to him and his rescuers. 4. The second man then places his safety straps between the legs of the victim and moves up the pole. He then lets the victim’s back rest on his breast to relieve the victim’s waist from strain caused by his body belt. 5. Rescue breathing shall be continued as long as necessary on the pole or structure. The second man shall assist in lowering the victim to the ground when the need arises to wit: a. Where artificial respiration is impossible to perform on the pole. b. When the victim has been revived or rigor mortis has set in. Note: the second man should be very careful in doing his job so that it will not interrupt the artificial respiration being performed by the rescuer. Heartbeat Stopped: 1. The rescuer shall announce to the men below that the heartbeat of the victim has stopped. The foremen shall then assign one of his men to call an ambulance. 2. The second man shall then prepare, as quickly as possible, the hand line for lowering victim and shall stand by to assist in the lowering operation. 127 3. The victim shall be lowered as soon as possible. 4. As soon as the victim reaches the ground, he shall be held on his back on a firm and rigid surface. 5. Mouth to nose or mouth-to-mouth resuscitation and closed chest heart massage shall be administered immediately and simultaneously. 6. As soon as the ambulance arrives, the injured shall be taken to a hospital with cardiac defibrillators. During the trip to the hospital, artificial respiration and heart massage shall be continued in the ambulance. At the hospital, the injured shall be turned over to the attention of the medical staff who must be immediately informed that the injured was a victim of electric shock and that his heartbeat has stopped. F. Should there be any difficulty in administering the mouth to nose method, then the mouth-to-mouth method shall be administered.
