M. Environmental Setting,Impacts,and Mitigations A. Land Use,Plans and Policies The proposed project would convert approximately 126.4 acres of agriculturally-used land recently purchased from the California Youth Authority(CYA)to landfill-use. Activities on the proposed CYA expansion area include borrow area for fill cover,siting for administrative buildings,and a leachate detention pond. Approximately 85.6 acres of agriculturally-used land (including one residence)south of the existing site(Brocchini Property)would be converted to landfill. A portable chemical storage locker with a double containment system would be used for temporary hazardous waste storage . The portable chemical waste storage locker would be located new the working face to reduce the risk of spills when moving the waste from the working face to the storage locker. The locker would be used to safely store intercepted hazardous waste before removal from the site. Hazardous wastes are not accepted under existing or proposed operation of the Austin Road Landfill. The locker would be used as needed, although this use would be sporadic and infrequent based on current incidence of hazardous waste retrieval at the existing landfill. A Department of Toxic Substances Control(DTSC) permit would not be required since the hazardous waste,mostly household hazardous waste, would be removed within 90 days and disposal of in accordance with state and federal regulations. The material would be disposed of at Forward,Inc.Landfill or taken to one of the household hazardous waste collection programs sponsored by San Joaquin County(Fukumoto, 1993). Only household hazardous waste from residential sources would be taken to the household hazardous waste collection events. An air district permit would not be required, assuming collection containers are kept closed. Flood control easenvent area would be established along the western and northwestern borders of the existing landfill site to accommodate flooding from the realigned the North Branch of the South Fork of Little Johns Creek. The 6.5 acre triangular site in the northeastern comer of the proposed expansion area is within the 100-year floodplain and would consequently be maintained as a floodplain area. The North Branch of the South Fork of Little Johns Creek course would be altered to accommodate the proposed project. 10.3 acres of the northernmost comer of the Brocchini parcel would be used as a wildlife preserve/floodplain area. The farm residence located on the current Brocchini property would be removed under the proposed project. The nearest remaining residence would be approximately 500 feet east of the Brocchini property (the future landfill boundary). The Northern California Youth Center would continue to be approximately 1,900 feet north of the landfall operation,but the project would III.A.22
