Surface Water Discharges <br />There were no surface water discharges from Sedimentation Pond Outfalls 001, <br />003, 005, 006 or 008 during the period from October, 1984 through December, <br />1984. Treated effluent from the wastewater treatment plant (Outfall 007) was <br />discharged during the period. Discharges also occurred from Outfalls 002 and <br />' 004 which are the respective normal dewatering outlets for Sedimentation Ponds <br />MB #1 and MB #2. <br />1 <br />' Analyses presented below show monitoring results required under NPDES Permit <br />No. CO-0038776 from discharges from the wastewater treatment plant. One <br />' exceedence of the BOD, 5-day effluent limitation (BODS) and total suspended <br />solids (TSS) limitation occurred during November. Two follow-up samples were <br />taken in November and analyzed for BODS and TSS. Both samples showed the <br />parameters to be well under the Mt. Gunnison NPDES permit effluent <br />limitations.
