Toxic Substances Control (DTSC). The WMUs at the existing Forward Landfill are pcnnitted to accept both Class II and Class III waste. The landfill has also received a variance to dispose of asbestos containing material (ACM). The existing Forward Landfill is currently pennitted to accept 6,680 tons per day of refuse. Other industrial operations on-site include a transfer station/resource recovery facility(which is currently being used for composting) and sedimentation/detention ponds. In addition, contaminated soils are accepted at the Forward Landfill for temporary storage until the required analytical testing is received. The existing Austro Road Landfill is an active solid waste landfill that accepts Class III wastes (municipal solid waste, including residential and commercial wastes). It is currently permitted to accept 1,200 tons per day of refuse. Other industrial operations on-site include a gas to energy power plant ("Cogeneration Facility") and a groundwater treatment plant (used to.treat contaminated groundwater at the existing Austin Road Landfill). The Cogeneration Facility is operated and permitted by Ogden Power Pacific, Inc. Both landfills make use of heavy-duty diesel powered mobile equipment to assist in the transport and landfilling of waste. In addition,both landfills.have plans to install additional landfill gas (LFG) collection systems as well as flares to abate the collected LFG. Ancillary activities at both landfills include an entrance facilities area, scales and scale houses, water production wells, and maintenance and storage areas. The landfills also have stockpiles of non-contaminated concrete to use for building roads on-site. Potential ancillary facilities that may be constructed include additional entrance and administration facilities. The following modifications are proposed for the landfill expansion: ■ Use the wedge between the existing landfills for placement of refuse; ® Lower the base grades in future waste management units at the existing Austin Road Landfill expansion areas to match the base grades at the existing Forward Landfill; ■ Raise the final grades at the existing Austin Road Landfill expansion area; ® Allow the combined landfill to accept Class II waste, Class III waste, and ACM; ■ Revise the hours of operations from 6 a.m. to 6 p.m., Monday through Saturday, at the existing Forward Landfill, and 6 a.m. to 3 p.m., Monday through Friday, at the existing Austin Road Landfill, to 4 a.m. to 12 a.m., Monday through Sunday, at the combined landfills; and ■ Combine the individual daily tonnage values for each existing landfill into one tonnage rate for the combined landfills. y:lForward-Austin/RepoNmasterrepo tt.doc 2-2 ENVIRON
