WASTE DISCHARGE REQUIREMENTS ORDER NO.115-2002-0072 5_ GEORGE REED, INC.AND 711 MATERIALS,INC. AGGREGATE MINE AND WASTEWATER SYSTEM SAN JOAQUIN COUNTY 33. Topsoil is removed from areas to be excavated and stockpiled; topsoil is then spread on reclaimed areas. Reclaimed areas will be used for agricultural purposes. 34. Surface Mining and Reclamation Act(SMARA) documentation has been submitted as part of the EIR and subsequent negative declarations. The reclamation plan describes returning the land to agricultural use when the excavation and processing activities end. BASIN PLAN, BENEFICIAL USES,AND REGULATORY CONSIDERATIONS 35. The Water Quality Control Plan for the Sacramento River and San Joaquin River Basins, Fourth Edition (hereafter Basin Plan) designates beneficial uses, establishes water quality objectives, contains implementation plans and policies for protecting waters of the basin, and incorporates by reference plans and policies adopted by the State Water Resources Control Board. Pursuant to Section 13263(a) of the California Water Code, waste discharge requirements must implement the Basin Plan. 36. Surface water drainage is to the Mokelumne River. 37. The beneficial uses of the Mokelumne River are agricultural irrigation, agricultural stock watering, contact recreation, canoeing and rafting recreation, other non-contact recreation,warm freshwater habitat, cold freshwater habitat, warm water migration, cold water migration,warn water spawning, cold water spawning, and wildlife habitat. 38. The beneficial uses of underlying groundwater are municipal and domestic supply, agricultural supply, industrial service supply, and industrial process supply. 39. State Water Resources Control Board Resolution No. 68-16 requires that the Regional Board, in regulating the discharge of waste, must maintain high quality waters of the state until it is demonstrated that any change in quality will be consistent with maximum benefit to the people of the State, will not unreasonably affect beneficial uses, and will not result in water quality less than that described in the State Board's policies (e.g., quality that exceeds water quality objectives). 40. The Regional Board has considered anti-degradation pursuant to State Board Resolution 68-16 and believes that this discharge will not impact underlying groundwater. No chemicals are added to the wastewater stream; the settling ponds are used only for settling out earth materials. 41. A Final Environmental Impact Report (EIR) dated 13 August 1990 was prepared for the San Joaquin County Department of Planning and Building Inspection. The EIR was adopted on 22 January 1991. Subsequently, several negative declarations addressing excavation areas not identified in the EIR have been adopted by the San Joaquin Community Development Department. 42. The applicable EIR measures for water quality are briefly summarized below: a. An erosion control plan shall be prepared if haul road bridge removal or replacement is needed.
