® Hazardous Waste Storage Locker. Household and other hazardous wastes segregated from incoming wastes through the existing Load Checking Program or found at the working face that cannot be returned to the transporter are temporarily stored in a special chemical storage building that is kept locked. Hazardous wastes generated by onsite equipment maintenance activities (i.e., changing of lubricating oils) are stored in the storage building until transported offsite for proper disposal. Maintenance and Storage Area. The maintenance and storage area is also located just south of the main entrance near the landfill office. The area is secured and fenced but also mobile and can be moved around the site, as needed. The maintenance area includes portable buildings, storage areas for refuse bins, and parking areas for heavy equipment and cars. A complete vehicle repair service facility with an extensive inventory of spare parts is also maintained. The maintenance and storage area is operated in accordance with the site's SWPPP. Landfill Gas to Energy Plant. A third party landfill gas developer, Covanta, currently operates a landfill gas to energy plant at the FL, along with a field of extraction wells in the former Austin Road Landfill. The developer collects landfill gas sufficient to produce up to 760 kilowatts per hour, which is sold to Pacific Gas and Electric Company (PG&E) under a long-term agreement. Additional gas extracted from the landfill is destroyed at the flare station, as described in Section 3.1.5. Groundwater Extraction and Treatment System. The northern portion of the existing refuse fill area is currently under a Corrective Action Plan (CAP) for groundwater contamination by volatile organic compounds (VOCs). To comply with the CAP, a groundwater extraction and treatment system was installed to mitigate chlorinated hydrocarbons detected in the first encountered groundwater beneath this area of the site. Landfill Gas Flare Station. The flare station consists of two enclosed ground flares, three blowers and associated control equipment. The two flares have a combined capacity of 5,400 cfm of landfill gas. The flare station collects gas from the majority of the site via an extensive extraction well system, and destroys the methane and other volatile constituents by carefully controlled combustion.
