MATERIALS HANDLING AND SPILL PREVENTION (BMPs) Several of the materials handling and spill prevention methods were described in Section 4, Potential Pollutant Sources (Materials Inventory). The Maryland Creek Ranch facility is covered under a Spill Prevention Control and Countermeasures Plan (SPCC), which is a separate stand- alone document. In addition, the following Best Management Practices (BMPs) have been adopted and implemented by Everist Materials, LLC (Everist). All material stockpiles which could potentially pollute stormwater with sediment are graded. Topsoil and overburden stockpiles are revegetated, as soon as practicable after materials placement. Raw material and product stockpiles are located within the pit, allowing for any stormwater runoff to flow toward retention/detention areas within the pit. The water that is used in the wash plant to separate the fines from the desired finished product is directed toward settling ponds to be recycled and used again. Raw material and product stockpiles have continuous rotation of material. No chemicals are used in the processing of the aggregates. Materials which could potentially pollute stormwater with hydrocarbons are kept in enclosed containers that are either double-walled or surrounded by berms or kept indoors. All are kept out of main traffic routes and on impervious surfaces. Spill control berms are of sufficient size to contain the contents of the tank, should a leak or spill occur (minimum 110% of the volume of the largest tank). Fueling of equipment is monitored to prevent accidental overfills and spills. Maintenance of equipment is conducted within the shop/storage trailer, or in the mobile equipment storage area, which is located within the pit. All mobile equipment is inspected daily for leaks or spills. If problems are noted during the routine inspection they will be promptly contained and repaired as soon as possible. Lubricating fluids are kept indoors in the shop or storage trailer. Trash is removed from the site on a regular basis. Trash receptacles are located near the shop and batch plant. 5
