Summer and Fall Water Report <br />1997 <br />Apex #2 Mine <br />Permit C-81-011 <br />Surface Water <br />In all of 1997, the single sediment pond for the entire disturbed area did not discharge; <br />it only contained water in the spring as a result of snowmelt. All disturbed area is <br />channeled into the sediment pond except for a small exemption area of less than 0.1 <br />acre located at the reclaimed office area. The sediment pond discharge is permitted <br />with the Colorado Department of Health as NPDES Permit #COG-850041. (The permit <br />was formerly CO-0036668). Quarterly DMR forms are attached for the year. Quarterly <br />sediment pond inspections revealed no problems with functionality of the pond. <br />Trout Creek, the perennial stream located adjacent to the reclaimed yard area, was <br />tested quarterly for pH, Specific conductance, temperature and flow. These results are <br />also attached for above and below the minesite. In 1997 a revision was submitted to <br />abandon the downstream monitoring site since it was possibly affected by the P&M <br />Edna Mine. The sample location was moved to immediately downstream of the <br />reclaimed area. The data for 1997 showed normal conditions, with normal flows in <br />Trout Creek due to good rainfall. Beaver activity was noticed downstream of the mine <br />on the Baumgartel property. <br />All portal seals are intact and do not show any signs of seepage or other problems. The <br />mine or its reclamation has not had any adverse effect on the prevailing hydrologic <br />balance. The diversion ditch above the minesite along the residential access road <br />required cleaning as did the culvert crossing of this diversion under the Trout Creek <br />Road. This work was also completed in the fall of 1997. <br />Ground Water <br />There are no monitoring wells in the permit area or in the surrounding area. In 1997 a <br />revision was submitted to install two new shallow groundwater monitoring wells <br />upstream and downstream of the mine reclaimed area. These wells will relace the old <br />upstream and downstream wells. This was done since the downstream well and surface <br />
