3.6 Proposed Project Components No downstream end through a concrete overflow structure. The benefit of this option is �. that the basin could then be used to control and manage flows and storm water along Hospital Creek and could act as a groundwater recharge basin. Under this option, reclamation of Phases V and VI would be a large seasonal pond. Public Safety ` The Applicant proposes to implement measures to prevent accidental and unauthorized access to the mining areas. The Applicant would install and maintain fencing,consistent with the San Joaquin County Code,and warning and no-trespassing signs around the perimeter of the property. Gates would be installed and roving security patrols would be employed during non-operational hours. Signs would be installed for regular traffic and delivery routes and lighting would be installed and maintained for traffic and safety purposes. Haul roads would be graded, watered, r. and maintained with berms for traffic safety. Slopes would be fenced to prevent public access and replaced at 2:1 per County Code requirements. Equipment, roads,fences, and security would be maintained in compliance with County Code, Mine Safety and Health Administration(MSHA) regulations,and Cal-OSHA regulations. Petroleum products and other hazardous materials would be stored on the site, including gasoline and diesel fuel, oil and grease, waste oil,antifreeze, used oil filters, solvents,batteries, gases, ready-mix admixtures. All petroleum products and hazardous materials would be stored in Lregulatory agency approved containers and secondary containment. A Hazardous Materials Management Plan (HMMP) would be prepared and submitted to both the San Joaquin County Environmental Health Department and the Stanislaus County Environmental Health Department. This plan would include an inventory of hazardous materials and hazardous wastes,how these materials are handled, how the wastes are disposed, and a hazardous materials and wastes emergency response plan.The HMMP would be located on the property at all times and ` employees would be trained on the details of the plan. Dust Control The potential sources of fugitive dust in the mining operations include: • Pit face excavation • Loading of haul trucks • Dumping material into the feed hopper • Transfer points on the field conveyors • Pit haul roads The mining operation will regulated by SJVAPCD Rule 8020. Dust suppression for the ` operations will include the watering of mining areas and haul roads by water trucks as necessary to reduce dust. Approximately 80,000 gallons per day of water will be used for dust suppression during construction,operation, and reclamation. In the mining operations the water will be applied by a water truck at the pit face and along the haul roads. Spray bars will be located at the feed hopper and at the field conveyor transfer points. A bag house will be used on most crushers, dry screens, transfer points,and.all plants to control airborne dust and emissions. i V RMC Pacific Vernalis Quarry Mining and Reclamation Proj3-21 ESA/203015 Draft Environmental Impact Report May 2006
