sediment ponds. Ponds 002-006 were visually surveyed for adequate sediment and water storage <br />capacity for the 25yr - 24hr event. They appeared to have sufficient capacity. Ponds 001 and 007 were <br />also observed during the year and no significant sediment inflowwas observed. Their sediment volume <br />should be adequate. <br />Were changes made to your SWMP for 2000? Yes <br />Sediment Pond 008 volume size was increased to the 25yr-24hour event standards by mining activity <br />and a permanent primary and secondary discharge structure was installed through the embankment <br />to assist in the SWMP plan. The design for this sediment pond was submitted and approved by the <br />DMG office. There was a partial 8-hour shift water discharge through this structure October 11"', 2000. <br />The discharge was by a small Shp gas pump. The discharge volume was estimated to be 72,000 gallons <br />of water. Before a W ET test sample could be gathered, the pumpage ceased and never was activated <br />again for the year. <br />At the New Horizon II area, all culverts and ditches leading into Pond 007 were capable of functioning <br />as designed. There was no measurable flow ihru these ditches the entire year. <br />B. A SUMMARY OF EACH COMPREHENSIVE STORMWATER FACILITY INSPECTION <br />MADE.... <br />New Horizon Mine is small enough in land area that all active areas in the permit boundary are <br />inspected for SWMP compliance daily, Monday -Friday. This includes ditches, culverts, <br />sediment ponds, diversion ditches, petroleum storagefacilities, and etc. Non-active areas, such <br />as established reclaimed areas awaiting reclamation bond release, are inspected weekly, with <br />detailed inspections monthly. Any deficiencies noted during any of the inspections were <br />corrected promptly. <br />In the New Horizon I area, no maintenance work was necessary. All ditches and culverts appeared to <br />be functioning properly. <br />C. RESULTS AND INTERPRETATION OF ANY STORMWATER MONITORING.. <br />F: \data\wpdata\storm\OOsumprp. doc 2-3 <br />
