1.0 INTRODUCTION <br /> 1.1 PURPOSE <br /> This Partial Final Closure/Post-Closure Maintenance Plan (PFCPCMP) for the <br /> Forward Landfill has been prepared to implement closure of the Stage IA closure <br /> area. Liquid seeps were observed which occurred during the 2004/05 winter <br /> season and reported by Forward Landfill Inc. (the permitted owner and <br /> operator/discharger) to the Central Valley Regional Water Quality Control Board <br /> (RWQCB). The seeps were observed in the area highlighted as the Stage I <br /> closure area in the 2003 Preliminary Closure/Post-Closure Maintenance Plan <br /> Revision (Plan). After notification by Forward Landfill Inc., the RWQCB <br /> inspected the site and subsequently issued a Notice of Violation. Storm events <br /> for the 2004/2005 season generated larger than normal amounts of rain <br /> throughout central California and certainly upstream of the Forward Landfill. The <br /> RWQCB's inspection of the Forward Landfill conducted on February 25, 2005, <br /> observed the following conditions at the Forward Landfill: <br /> ■ RWQCB staff followed up on a February 24, 2005 report from San Joaquin <br /> County LEA and Forward Landfill Inc. that leachate was seeping from the <br /> north side slope at the Austin Road unit and collecting in a ditch located at <br /> the toe of the slope. Multiple leachate seeps have developed along a line <br /> approximately 15 feet above ground surface on the west half of the north <br /> side-slope of the Austin Road unit. Minor quantities of leachate ran across <br /> portions of the north perimeter road and were collected in a storm-water <br /> ditch north of the perimeter road. The ditch is blocked at both ends and <br /> there is no evidence that leachate drained to the storm water collection <br /> system or to surface water. When discovered, Forward Landfill Inc. <br /> personnel pumped the leachate out for discharge to the leachate collection <br /> impoundment. <br /> On the northwest side of the Austin Road Unit, high water in adjacent Little <br /> Johns Creek overflowed its bank and, for a time, surface water was in contact <br /> with the foot of the landfill to a height of three feet.
