III. COMMENTS-COMPLIANCE <br />Below are comments on the inspection. The comments include discussion of observations <br />made during the inspection. Comments in Section IV describe any enforcement actions <br />taken during the inspection and the facts or evidence supporting the enforcement action. <br />Remaining reclamation at the site consists of removal of the bridge that provides <br />access to the "new" and Stony Ridge fan shafts. The existing road/trail to the bridge <br />provides access. Work consists of the removal of the deteriorated decking, the steel <br />superstructure, and the concrete abutments. These materials are to be hauled off to <br />an authorized disposal site. There are no unique aspects that would incur an unusual <br />degree of difficulty to complete this demolition work. A requirement to remove the <br />concrete foundations of the water monitoring flumes (2 each) on Middle and North <br />Thompson Creeks is under review. No demolition task was carried over from the <br />approved Phase I bond release. In the event this demolition work is determined to be <br />an oversight, the removal of the flume foundation on North Thompson Creek near the <br />Refuse Area Sedimentation pond may require the use of track equipment or all- <br />terrain rubber tired equipment to minimize impact to reclaimed vegetated areas. <br />Road access to the other three flume foundations is available, but long-reach <br />equipment may be required to minimize disturbance to well-established riparian <br />areas and the streambeds. The two monitoring wells D-1 A and D-2A in the vicinity of <br />the toe of the Refuse Area will need to be reclaimed, and eventually, all signs and <br />markers will need to be removed. There does not appear to be any unusual degree <br />of difficulty in accomplishing this light work. <br />3) pollution of surface or subsurtace water (Rule 3.03.2(2)). <br />There was no visual evidence of pollution to surface or subsurtace water or receiving <br />streams of the reclaimed areas or permanent features of the sites. There are <br />drainages from the airshaff at Mine 1 and the Portal of Mine 3. These drainages are <br />collected and piped to water treatment ponds (features of the Developed Water <br />Resource land use area), and eventually discharged to North Thompson Creek. An <br />electric pump was installed at Pond 2 of the treatment system, and a piping system <br />was observed, whereby water can be piped to a stock tank, The Colorado Division of <br />Public Health and Environment (CDPHE) permits discharge from the water treatment <br />pond to North Thompson Creek. An office review of Colorado Discharge Monitoring <br />Reports finds that the discharge has been consistently in compliance with the <br />(CDPHE) discharge permit. <br />Two monitoring wells, D-1 A and D-2A were observed during the inspection. They are <br />located near the toe and in the vicinity of the Refuse Pile Sedimentation Pond. Well <br />D-2A is located outside any potential plume of the refuse area. D-1 A is located in the <br />embankment of the Refuse Pile Sedimentation Pond, directly below the refuse pile <br />area. Baseline information in the PAP (page 3-52) indicates that both of these wells <br />contained water having high total dissolved solids concentrations. In 1980, <br />conductivity in samples from Well D-1 A ranged from 2100 to 4000 with a mean of <br />2951; samples from Well D-2A ranged from 770 to 3065 with a mean of 2447 (PAP <br />C-81-025, Page _6_ of _8_ Pages, (date) _2 October 2001_, (initials) .GjY~/ <br />
