43 Potential Pollutants <br />Potential pollutants that could contaminate stormwater runoff from this site include, but are not <br />limited to sediment, diesel fuels, gasoline, motor coolants and lubricants. <br />4.4 Discharge Samplinng Data <br />There is no existing discharge sampling data describing the curtent stormwater discharges for this <br />site. Almost all stormwater that comes into contact with various aspects of the mining operation <br />is routed into the sediment ponds. <br />5.0 STOR1~1V1'ATER QUALITI' CONTROLS <br />5.1 SVJMP Administrator <br />The Vice President of Castle Concrete will be responsible for overseeing the maintenance and <br />revisions to the SV1MP. All changes will be noted directly on the report or maps for <br />incorporation into the plan. <br />5.2 Risk Identification and Assessment <br />Loading of haul vehicles to remove the aggregates from the site, occurs near the stockpiles. Care <br />is taken to avoid damaging the vehicles and releasing any potential pollutants onto the site. <br />Equipment used for the extraction and hauling of the aggregate is stored on-site. Front-end <br />loaders and dozers are stored near the maintenance building. Haul trucks are stored there also. <br />Daily inspections of the equipment and parking areas occur before the vehicles are moved. Daily <br />maintenance occurs on-site, at the parking locations. Oil changes and overhaul maintenance are <br />conducted on-site, and inside the maintenance building. If any spills are noticed they will be <br />cleaned up promptly and the contaminated soils disposed of in a manner consistent with applicable <br />environmental laws. The source of the leak will be identified and measures taken to~revent any <br />further discharge. <br />1 Fuel tanks are located near the maintenance building, and are surrounded by an earthen berm of <br />sufficient size tb contain the contents of a full tank should a leak or rupture occur. Generally <br />there is no more than 1,000 gallons of combined used and new lubricating and hydraulic fluids at <br />1 any one time at the site. <br />This site has no areas of historic mine drainage or spoil springs that could contaminate stormwater <br />dischazges. <br />This operation does not use tailing ponds in the process of creating the aggregate. <br />1 Screening and crushing of the aggregate occurs daily with this operation. The crusher and screens <br />aze powered by electricity. <br />1 3 <br />
