PCC 11 /92 page 4 The following are conditions observed that exhibit potential to develop into violations if PCC does take some remedial action in the near future. These conditions are not in violation at the time of this inspection. Cameo Mine All pipes to the evaporation pond have been disconnected so I did not consider it as an impoundment. If PCC decides to use this structure again, the impoundment regulations will apply and the pond must be certified. The only water that reaches this location is what precipitation falls on it. PCC needs to clean out the sediment that has accumulated in front of the portal. During the inspection, only mine water was being discharged from this mine. A potential for surtace and groundwater to commingle exists due to the method currently being used to dewater the mine and the lay out of the site. PCC must realize that if there is a commingling of water, a siltation structure big enough all water must exist. There were some oil buckets near the shop/yard (?) area that need to be cleaned up._ North Decline - , The inlet to pond #7 was eroded. There was not any channel lining at all in the ditch and inlet to this pond. PCC placed haybales in this location prior to the end of the inspection. DMG allowed this as a temporary fix only. PCC must provide long term protection within thirty days. The haybale ASCA at the west end of the site had been grazed away by livestock. These were replaced during this inspection. The potential for a grazing violation to develop after the site is seeded exists because the area is not fenced. PCC should examine the question of how to keep livestock off the site during PCC's liability period. The substation and shed will be removed before the area is seeded. Seeding will take place before the end of the planting season. If it is not done during this period, a violation will exist. Final grading took place in June. The as-built certification for the new pond #7 should be submitted before the end of the month. Roadside The lower catch ditch to pond #9 needs to be deepened to the design depth. the pond. Pond #8 inlets are eroding. These are at the South and North ends of The 18" CMP on the North end of the pond needs cleaning. The sediment level is approaching clean-out stage. All other paper work and permits appeared to be up to date. All monitoring appears to be done according to plan. The subsidence monitoring was discontinued upon the approval of DMG. Liability insurance and bonding documents appeared to be in order.
