LGU of Ozamiz City

Proposed Ozamiz City Sanitary Lanctfill Bgy. Kinuman Norte, Ozamiz City, Misamis Occidental

Feasibility Study and Pre-Engineering Design

• Review relevant technical information used for design of the proposed landfill and its other engineering features ;

• Readiness filter of the project to the requirements of S2LDIP environmental safeguards framework.

Technical Information on the Proposed Project:

• The sanitary landfill (SLF) will be constructed in Barangay Kinuman Norte about 15 km from the town proper. The proposed disposal area is about 5.7 hectares located inside a 15-hectare property owned by the LGU Ozamiz City.

• The area is agricultural but was already identified as a potential landfill site as indicated in the 2000 Ozamiz City's Comprehensive land Use Plan. Hence, the area is compatible with the existing and approved land-use plan of the city.

• The. FS (assumed conducted in 2002-2003) presented the projected solid waste generation rate for 2005 to 2025 using the 2000 census as its baseline. The estimated generation rate was about 33,000 to 50,000 m3 (16,000 to 25,000 MT) per year depending on the waste diversion to be implemented. (Note: The FS used a 500 kg/m3 compacted density of solid wastes.]

• This projection rate translates to about 100m3 (50 MT) of wastes to be disposed off in the proposed landfill per day. The LGU collection capacity (trucks and personnel) for year 2002 was reported to be only 40 to 50 m3/day as collected from 15 barangays out of the total 51 barangays of the city (23 urban and 28 rural).

• The waste analysis and characterization study (WACS) conducted by for the FS revealed that about 77% of the household wastes were biodegradable with a moisture content of 62%. The WACS indicated that commercial and institutional wastes contain 55 to 88% biodegradable components with 34 to 81% moisture content. However, the WACS did not quantify the weight percentages of households against commercial and institutional wastes (i.e., how much of the 40 to 50 m3/day collection are from household sources or how much of the totaJ collection are biodegradable?).

• The FS provided detailed technical descriptions of the various project components. The proposed landfill is an anaerobic bio--reactor type sanitary landfill with the following features:

a. Disposal area divided into 3 cells: - Cell 1: 1. 7 ha (5 years estimate life-span) - Cell 2 & 3: 2 hectares each cell for use in the next 10 years

b. Liner system (double liner using 1.5 mm HOPE geo-membrane) c. Leachate management system (leachate will be re--circulated to the disposal area;

pre-treatment was proposed using aerobic contact process) d. Off-site drainage and run-off control system e. Gas release and monitoring system

Environmental Considerations on the Proposed Project:

• The FS presented pre-project baseline information on the environmental conditions in the area as described by the topography, hydro--geological and climatological sections of the FS.

• The proposed site was already assessed and evaluated by the Mines and Geo­sciences Bureau (MGB) in Region X. MGB assessment report was induded in the FS along with the recommendations made for the proper design of the landfill. Several environmental issues were identified by the MGB saeening checklist and were property answered by the Proponent Such issues included the following:

Issues Answers a. Proximity to • The closest water supply SOU"ce is located on the

groundwater upslope side of the proposed landfill about 2.5 k resources away.

• A shallow well is located 300 meters SE of the prUVC'I 'Y currently used by 2 households.

b. Proximity to surface • There is an ephemeral creek 400 meters N of the waters property. Proper leachate management was

committed in the FS. c. Occurrence of • The reported elevation of the area is 400 to 460 mas!

flooding (relatively high , .. uuJVared to other areas in the cit~)-d. Proximity to sensitive • There were few households within the 500 meter

landusers radius. • The area is not known for any archaeological, cultural

and historical significance. e. Proximity to protected • The Mt. Malindang National Park is about 10 km from

areas the ~roposed site. f. Seismic condition • Last recorded earthquake was on April 1, 1955

(magnitude 7.5) with epicenter between Lake Lanao and Panguil Bay.

g. Geologic condition • The Western Mindanao Extension Fault, a NE-SE trending fault is 12 km N of the area.

• There are no known sinkho~es. caverns. jointed or fissure rocks in the area.

• Another issue raised in the MGB assessment was the presence of a shallow water table (about 2 meters) in one of the boreholes tested by MGB. Since the rest of the boreholes yielded 6 to 18 meters water table, MGB recommended further study in that particular borehole site during the detailed engineering. The 2-meter water table issue will be a critical factor on the type of the fandfiU liner system that will be used and on the final location/configuration of the disposal area.

• The Site Management and Operation Section of the FS already addressed the possible impacts of the proposed project to the surrOl.llding environment. The FS identified environmental management measures to address the issues on noise, dust generation, siltation and erosion, odor, vectors & pest oontrol, and fires. These commitments will just have to be dev~oped into an Environmental Management Plan and an Environmental Monitoring Program (in matrix formats as prescribed by DENR­EMB) for easier monitoring.

• From the information in the FS, the Environmental Compliance Certificate of the project is yet to be secured. The EMP and EMoP may be developed during the ECC application. This has to be verified with the Proponent.

Other Considerations for the Proposed Project:

• On the institutional aspect, the Solid Waste Management Board as mandated by RA 9003 was already constituted by loc:a& Executive Order #1 s2002 and its Technical Working Group (LEO #1 s2003) was also already operational.

• The FS presented two options on how the project will be institutionally managed: (a) landfill will be operated by private operator or (b) the landfill will be operated by the LGU using its present manpower_

• The total project cost is P110 million with an initiaf CAPEX requirement of P40 million for Phase 1. The cost included the construction of the disposal cell, gas collection, leachate management, run-off control, double liner system, monitoring wells and other support facilities. The costs did not include procurement of collection trucks and the establishments of MRFs and composting facilities (which were identified as project auxiliaries).

• Since the SWMBITWG was already constituted since 2002, it is assumed that there were SWM programs already launched by the LGU. As mentioned in the FS, intensive IEC campaign per barangay on solid waste management; the establishment of MRF in barangay levels; and the prCXU'ement of a bio-reactor from OOST for market wastes were already committed by the LGU. The status of these programs and their milestones may have to be documented and evaluated.

• The impact of these initiatives on the final amount of wastes (quantity and quality) must be evaluated to see if the proposed bio-reactor type of sanitary landfill is still a viable option. The intention of RA 9003 is to promote the construction of SLF that will only accommodate the residual wastes after recycling and cornposting in the MRFs (i.e., less biodegradables ending up in SLF).

Recommendations:

• Proponent must review and update the waste generation rate of Ozamiz City using updated information on population and number of commercial establishments. The operations of barangay MRFs and composting facilities must also be evaluated to establish the residual amount of wastes that will be received by the proposed SLF.

• Proponent may have to review the viability of the bio-reactor type sanitary landfill vis-a­vis the amount of biodegadable wastes that will be received by the landfill after the wastes are processed in MRFs and composting facilities.

• As prescribed by RA 9003, all LGUs must now have reduced the wastes ending up in dumpsites/SLF 25%. The progress of the LGU compliance on mandatory waste diversion requirement of the law must be considered in the waste_ generation projection.

• Proponent to secure the necessary envirormental permits including the ECC (if this was not yet secured since 2003). Based on the amount of wastes to be received by the landfill (< 1,000 MT per day), an Initial Environmental Examination must be prepared. However, the project must be screened with EMB Region X.

• Proponent must validate the results of the geotechnical investigation conducted by MGB where one of the boreholes tested yielded water in just 2 meters. This will have an impact on the design of the sanitary landfill particutarty on the lining system.
