., L (Page 2) MINE ID f OR PROSPECTING ID f M-80-244 INSPECTION DATE 8 12 94 INSPECTOR'S INITIALS ACS OBSERVATIONS 't ~I~. Aw-i~apact~en Cresson Project Phase 1 pad area was inspected. An inspection of the Victor Pad was also conducted, including cursory inspection of the Ironclad and Globe Hill pits and the Squaw Gulch area. The Phase 1 underdrain sump has been excavated to the approved grade and has been lined with VLDPE. At the time of this inspection water was being pumped from the sump past the Carlton Mill tails and discharged into lower Arequa Gulch. There was water flowing into the sump from both the 24" solid pipe and from the 24" perforated pipe. The water entering the sump from the perforated pump was cloudy due to a heavy load of suspended eolide. The operator was instructed to put some sediment controls in place at the pumped water discharge point to filter the suspended eolide. The controls utilized should be in accordance with the Beet Management Practices described in the storm water permit for this site. The operator stated that sediment controls would be installed commencing immediately. During Phase 1 leach operations, the operator intends to maintain a pump in the Phase 1 underdrain sump with an approximately 300 gpm capacity. This should be orders of magnitude more than adequate to handle underdrain flows during normal operations, and it would not be difficult to increase pumping capability in the sump if it should become necessary. The Phase 1 toe berm foundation was inspected. The underdrain installation was complete in this area. The contractor was placing and compacting select structural fill preliminary to installation of geotextile and geomembrane. Once the geomembrane ie installed over the underdrain in this area, and covered with protective fill, the contractor can begin construction of the main portion of the toe berm. The current upstream extent of the underdrain was inspected. The 4" and perforated 24" pipes have been capped at the upstream ends and temporarily buried. A VLDPE lined temporary sump has been constructed to collect Arequa Gulch flows, primarily from the Arequa Gulch spring. A screened riser has been attached to the solid 24" pipe in the temporary sump, and the Arequa Gulch flows are conveyed to the Phase 1 underdrain sump through the solid pipe. The contractor is placing fill for the processing plant access road just below the current upper extent of the underdrain. An area of fill containing tree roots and other deleterious material was noted. The contractor was instructed to remove this unacceptable fill. The removal was completed before we left the site. in place lifts of primary underdrain were inspected. The underdrain fill exposed for inspection was very durable, and contained few if any fines. The contractor was breaking up oversize using a small excavator equipped with a jack-hammer attachment. The main topsoil stockpile was inspected. controls (hay-bales) had been washed out instructed to repair these ditch controls, water controls through-out the site. It was noted that some roadside ditch sediment and were non-functional. The operator was and to perform continuous maintenance on storm The Victor Pad was inspected. An area to the north and below the pad that was reclaimed two seasons ago ie doing very well with a good stand of grasses established and no significant erosion noted. An area on Victor Pad phase 5 was examined were material had been placed very near the edge of the pad. The material could block and pond etormwater flows at the perimeter of the pad, and potentially result in excursions of process fluid off the lined area. The .operator was instructed to remove all material from near the edge of the pad. This corrective action was initiated while we were still at the site, and was completed by the time the Division inspected the Bite on 8/14/94. Leak detection pipes on the south aide of the pad were inspected and were not flowing at the time of the inspection. cc: Berhan Keffelew, DMG Jim Pendleton, DHG Jim Dillie, DMG I & E Contact Address Carl Hount, DHG ^ ~ NAHE John Hardaway ^ BL OPERATOR Crinnle Creek & Victor Gold Co. ^ FS STREET P.o.
