Page IV.E-7ort Pa Draft Environmental Impact Report g Forward Inc. Landfill Expansion Project leachate. The existing Forward Landfill has a separate permit for land discharge of cannery wastes,but cannery wastes are not accepted for disposal. From an air quality perspective,the implementation of the project would potentially affect landfill gas(LFG)-related emissions (i.e., fugitive LFG and emissions from LFG control devices) and mobile source emissions from the increased haul vehicle activity(i.e.fugitive dust from roads and diesel particulate emissions). Based upon data from other landfills,toxic air contaminants(TAC) constituents within LFG typically consist of benzene, chloroform,methylene chloride,perchloroethylene (PCE), trichloroethylene(TCE),vinyl chloride(VC), as well as other TACs. Mobile sources emit diesel particulate matter (DPM), a TAC. TACs are also known as HAPS. Information about current TAC emissions from the landfill is presented in various tables provided in the SCS (2008) HRA. The anticipated closure date for the existing Forward Landfill is 2017. The expanded project would dispose a total of 8,668 tons per day, the same as currently permitted.In addition,the expanded project would accept 500 tons per day of recoverable materials at the MRF,5,487 tons per day of beneficial reuse materials,and 40,000 gallons of high moisture content waste. The proposed project assumes 960 versus 620 vehicles per day. This would occur over 7 days a week, as is the baseline case, with closure of the combined landfill being in extended 2032. These changes could affect the health and safety of workers at the landfill by potentially exposing them to a variety of contaminants in air, soil or water that are associated with the materials brought into the landfill. Fugitive dust with airborne contaminants could be inhaled, dermal contact and ingestion of contaminated soil and/or water could occur. As described earlier, the risk assessment completed by SCS was most sensitive to the diesel particulate emissions. Most of the increased cancer risk is due to the increased diesel particulate emissions from haul vehicles. The risk from moving haul vehicles accounts for over 80% of risk attributable to diesel particulate at the maximally exposed receptor and the maximally exposed occupied receptor. A summary of the key landfill operational commitments that result in a lessening of the risk factors in the proposed project are shown in Table IV.E-1, below, which compares the baseline assumptions with the proposed project assumptions. In addition, the following procedures are proposed as part of the project: • Use a total of 17 ieces of equipment (at any given time) over the life of the project to P minimize particulate discharge, will remain unchanged. • Operations at the combined landfill would be limited to a single working area at any given time. • All employees would be given appropriate training regarding the potential for exposure to hazardous materials. This training will include a 24-hour hazardous waste operations course and an annual 8-hour refresher course for personnel involved in the "load checking" program where the incoming loads are screened for hazardous materials. • The landfill would not accept any special waste that may potentially contain hazardous levels of regulated substances. • Dust control procedures specified in the Site Operations Plan (per the JTD) would use the application of fine water spray at a minimum of twice daily on the active soil- covered work areas, soil excavation areas, and soil stockpile areas where fugitive dust may exist.
