NPDES permit #COG-850018 expires 6-30-97. 4th quarter, 1994 report was <br />submitted 1-16-95. <br />Surface Water monitoring - 2 locations -Upper and Lower Hayden Gulch. These <br />areas are sampled on asemi-annual basis. <br />Ground Water monitoring -Well HG-1 sampled on semi-annual basis for quality <br />and quantity, Well UC-2 sampled semi-annually for quantity. <br />Liability insurance is combined with Colowyo permit with a total of 2,000,000 each <br />occurrence and 2,000,000 aggregate. Policy expires 6-30-95. <br />Permit renewal was approved in 1992 and expires in 1997. That renewal removed <br />the woody plant density requirement from the revegetation plan for the West area <br />and reduced it to 500 stems/acre for the East area. Post mining land use is grazing <br />with wildlife secondary. <br />Field Conditions: <br />The vast majority of the East area was under snow cover and could not be <br />inspected this date. Pond 4 (HG-8) was discharging. HGCC is drawing the pond <br />down so that repairs can be made to a small leak noted in the principal spillway. <br />Field analysis found pH 7.8. The discharge exhibited a strong sulfur smell. Also, <br />even though the discharge appeared clear, a faint discoloring of the stream bottom <br />was occurring (blackish film settling on rocks and vegetation). East fork of Williams <br />fork is the receiving stream. This condition should be monitored. <br />The rip-rap material that is being utilized for the emergency spillway and the <br />reconstructed drainway in the East area is disintegrating. The current sizing of the <br />material may be less than is required to protect the structures as designed. Mr. <br />Dudash indicated he would review this situation with DMG hydrologists. <br />Disturbed areas on the West area appeared to be stable. The following structures <br />were inspected and found to be in good order: <br />Pond #2, Pond #3 - No discharge from either pond <br />HG-1, UC-2(LC-2) Well sites <br />Upper Hayden Gulch Surface Water Monitoring site <br />Lower Hayden Gulch Surface Water Monitoring site(located on East side) <br />Pond #1 -snow cover precluded inspecting this site <br />The diversion that is located on the Southern side of Pond #3 needs maintenance. <br />Resizing and possible armoring should be evaluated. <br />The access road into, and along the Norther edge of the West area, will have to be <br />reclaimed or approved as a permanent structure prior to Phase I bond release <br />considerations. <br />
