TABLE 3.1 SUMMARY TABLE OF SIGNIFICANT IMPACTS AND MITIGATION MEASURES <br />WILL IMPACT BEI LESS <br />POTENTIALLY SIGNIFICANT IMPACTS:: <br />SUGGESTED MITIGATION ,MEASURES <br />THAN SIGNIFICANTo ... <br />Existing surface soils are inadequate to support foundations for <br />Construction of fills, foundations, slabs, and roadways on the <br />Yes <br />the proposed project facilities. <br />site shall be in accordance with the geotechnical engineer's <br />recommendations contained in Appendix F. <br />Construction of the proposed project facilities would promote <br />Placement of plastic sheeting, debris fences, silt fences, and/or <br />Yes <br />surface soil erosion. <br />hay bales to protect disturbed surfaces during precipitation <br />events during construction. Following construction, all <br />disturbed surfaces, especially slopes, shall be revegetated. <br />Water Resources <br />Construction of on-site drainage, as proposed. <br />Yes <br />Surface water contamination may occur from discharge of <br />Evaporation/collection pond for surface runoff from the active <br />surface waters or storm waters that have become contaminated. <br />working area (the yard and wood waste area) shall be lined. <br />All surface areas involved in the transportation, processing, or <br />storage of wastes shall be paved or lined and drained to an <br />appropriate catchment facility to prevent contaminated runoff <br />from entering the surface and ground water. <br />The proposed receiving and processing operations shall take <br />place within covered and paved structures. The outdoor wood <br />and yard waste composting area shall be paved or lined. <br />Except for yard and wood waste, there shall be no direct <br />precipitation onto wastes and contamination of surface water. <br />All buildings shall be constructed so that storm runoff shall not <br />enter and come into contact with waste or recovered materials. <br />Liquids leached from the received wastes and washdown water <br />used for periodic washdown of the transfer station floor shall <br />be directed into holding tanks or lined evaporation ponds and <br />then pumped into trucks for appropriate disposal in accordance <br />with Federal, State, and local requirements. <br />Areas containing equipment shall be curbed to contain <br />petroleum product and hydraulic fuiid leaks. Truck washing <br />areas shall be equipped with trench drains to collect waste <br />water. <br />ER -93-1 -23- (9-27-93) <br />
