As a result of this application, the existing <br />[nine approval (Permit COG850021) for stormwater discharge tinder the Goal Cetteral Permit <br />~'~ was converted to aft ittdividttal Industrial Discharge Permit (Permit No. CO-0043567), During <br />the period of active mine water discharge, Kerr complied with all applicable permit provisions <br />including specific sampling and reporting requirements. Mine water disdtarge ef[ectively ceased <br />on January 22, 1994 and nu further mine water discharge is anticipated. Witlt this transmittal <br />Kerr, tltereforc, respcahrlly requests that the WQCD convert rite existing approved permit <br />(Permit No. CO-0043567) back to a site stormwa[er approval under the Coal Ccncral Permit. <br />yt~ All accumulated mine water Itas now been discharged and all mine pit areas have been <br />~' backfillcd, regraded, and surface drainage has been reestablished as illustrated by fife <br />accompanying photographic copies. All future Flows to existing sedimentation points and <br />discharge from rite associated CDPS discharge points will be solely front surface runoff from <br />mine disturbance areas with nu mine or process water contributions. Ken- currently anticipates <br />completion of planned soil material replacement and revegetation nn the reclaimed areas by late <br />- fall 1994. At that time, Kerr plans to submit a request for consideration of a modification of <br />effluent limitations consistent with the change from active to postmining outfall stouts. <br />Given that initial snowmelt has begun in the area, Kerr would greatly appreuatc your assistance <br />in expediting this reyurst so as to avoid the additional sampling/analysis reyuiremettts tender fife <br />current approved permit. I would also request that in the permit conversion process you refer <br />back to my leucr of December 16, 1993 (copy attached) relative t:o consideration of the <br />following specific issues: <br />• Effluent limitations for iron for older discharges (3.Omg/1 vs. 1.0 mg/1) <br />• stormwater Management Plan requirements <br />• New vx, existing facility (relative to economic and other impacts with respect to <br />effluent limitations) <br />Steamboal Springs, CO.
