6.5 Truck Ready Line <br />Source <br />The major source of possible stormwater contamination derives from potential past <br />leaking or dripping of fuel and oil from equipment that was parked in this area. Because <br />this is a non-paved area, sediment may also be transported during periods of high runoff. <br />Risk Assessment <br />Risk of contamination in this azea is low. The potential for sediment transported by <br />runoff is also low because the azea is essentially flat. This means that flow velocities will <br />also be low, thus reducing the possibility for sediment erosion and transport. <br />Applicable BMPs and Good Housekeenin¢ Practices <br />A collection pond exists at the terminus of the drainage from this azea. The collection <br />pond collects flows from the equipment pazking and ready line. The pond is inspected on <br />a regular basis during storm events to ensure that overtopping does not occur. <br />Hydrocarbons, if present, are removed through the use of sorbent booms on the pond <br />surface. The following BMPs and general housekeeping practices will further reduce the <br />possibility of contaminated runoff: <br />1. The Emergency Response Plan (DMG, TR-27) will be followed in the event <br />of a spill of oil or lubricants. Contaminated soils and materials will be <br />collected and disposed of in an appropriate manner. <br />2. The collection pond will be regularly inspected and maintained to ensure that <br />sediment collected in the pond has not inhibited the pond storage or its <br />function. <br />6.6 Crusher and Ore Stockpile Area <br />Source <br />The crushing facility is located so that drainage from the area will runoff to the tailing <br />disposal facility with the exception of the northem perimeter of the crushing facility. <br />Surface water runoff from the northern perimeter area will drain to the sediment pond <br />located north of the equipment ready line. The crusher is therefore not a source of <br />potential stormwater runoff contamination. Ore was completely removed from the ore <br />Battle Mountain Resources, Inc.
