4-5 As mentioned in Section 4.1, the LFGTE facility (i.e., the former Covanta plant) has been shut down as of October 23, 2012. It is anticipated that a new LFGTE facility will become operational in spring 2014, as discussed in Sections 5.2.7 and 7.5. The power will be sold to Silicon Valley Power, which is the City of Santa Clara's power company, and will utilize Pacific Gas and Electric Company (PG&E) transmission lines. Presently, the gas extracted from the landfill is destroyed at the flare station at the northeast portion of the landfill. The landfill's Austin Road Unit is currently under a CAP for groundwater contamination by VOCs. To comply with the CAP, a groundwater extraction and treatment system has been installed to mitigate detected chlorinated hydrocarbon in the first encountered groundwater beneath the Austin Road Unit All site surface water that has not come in contact with waste is directed to the sedimentation ponds. Three sedimentation ponds are on-site. Two are located on either side of the South Fork of South Littlejohn's Creek in the southwest corner of the site. The third sedimentation basin is located along the western boundary of the landfill. Water collected in the sedimentation ponds is sampled in accordance with the site's Stormwater Pollution Prevention Plan (SWPPP) before it is discharged to the North or South Forks of South Littlejohn's Creek. 40 4.2 Permitted Waste Types Permitted wastes that may be currently discharged at the Forward Landfill are listed below. Several of these wastes are also approved as alternative daily covers (ADCs). 1. Nonhazardous solid wastes and inert wastes, defined by 27 CCR, Sections 20220 and 20230 as nonhazardous and nondesignated wastes that do not contain soluble pollutants that could be released in excess of water quality objectives or could cause degradation of waters. 2. Designated wastes (also referred to as "Class II Wastes") defined by 27 CCR, Section 20164 as nonhazardous wastes that contain pollutants that could be released in excess of water quality objectives or could cause degradation of waters, or hazardous wastes which have been granted a variance by the DTSC to be disposed in a Class II unit. 3. Wastes that meet the Class II and III criteria for waste disposal as specified in the WDRs issued by the RWQCB for the site.
