2. Area Subject to Effluent Limitations Guidelines <br />Each plan shall describe the portions of the mining site which contribute runoff to areas subject to <br />effluent limitations guidelines contained in 40 CFR subchapter N. <br />Many mining sites are already regulated under other federal and state programs. The federal <br />regulations are under 40 CFR, Section 440 - Ore Mining and Dressing. This section covers the <br />mining milling, etc. of metals If your site has a discharge of mine water, processing water, a <br />draining portal or adit, or runoff from any active mining areas; that discharge must be covered <br />under a CDPS industrial discharge permit. This is not the same thing as your CDPS stormwater <br />permit. The areas from which such discharges occur are then covered under the industrial discharge <br />permit, and so are not regulated under your stormwater permit. Some sources of stormwater which <br />are not addressed under effluent regulations are roads and railroad lines, pond outslopes, inactive <br />loadouts (coal mines), sites for storage and maintenance of material handling equipment, etc. <br />2. Area Subject to Effluent Limitations Guidelines <br />The Cash Mine and Who-Do Mine site does not have any industrial water discharges. <br />There is a tailings pond in the northern portion of the site. The tailings pond is zero discharge <br />and is protected from storm water runoff by grading, ditches, and berms_ There is no stormwater <br />contact with mill processing chemicals. <br />The mine openings on the site do not have any groundwater discharges. The Site has been. <br />evaluated and no discharges other than stormwater discharges have been identified with the <br />following exception: small amounts of water seep from the hillside near the Mount Royale adit <br />and near one of the inactive adits. This water is considered to be shallow subsurface flow of <br />surface water, not groundwater. These discharges are allowable non- stormwater discharges <br />under the general stormwater permit for metal mining operations (Part 1.113). <br />J ::IMinesLSWWMP1F.ula- Kingslrnmp rev 11 -99 4 <br />November 1, 1999 <br />1 <br />
