SMC 10/92 page 3 The MLRD permit expires 10/11/93. The CO Dept. of Health water quality permit is CO-0000132 and expires 10/31/96. The MSHA number is 05-00294. The insurance, #CLP 2 108 717, expires 8/1/93. The east yard pond, Hubbard Creek pond, #'s 1-7, 9-12, and pond 14 have construction certifications dated 8/1/84. Pond # 8 was certified 7/15/87. The mine water pond was certified 11/25/91. Annual certifications are not being done on the mine. The site lies within 100' of a cemetery and this was addressed during the permitting phase. The new Sanborn Creek disturbance is within 100' of the ROW for the state road. A letter dated 2/28/91 from the road authority allows this disturbance. The Bear Canyon area has three portals. These portals have temporary seals. The tops of the canopies are still evident. Buildings have been removed, but their concrete pads still remain. The substation has been largely stripped of useable parts and the skeleton remains. All areas have what MLRD calls SAE's; meaning that the runoff does not have to go through a siltation control structure. The approved sediment control measures are vegetation and silt fences. The Hubbard Creek area has two disturbed areas. The lower Hubbard Creek site has two portals with temporary seals. The concrete canopies still remain. There are concrete pads remaining also and a substation skeleton. The runoff from this area drains through a silt fence. SMC will have to do a stream channel reconstruction when the access road to the site is removed. The 8' CMP under the access road that Hubbard Creek drains through is scheduled to be removed. This creek is classified as a perennial stream. The disturbance is within 100' of the creek, but that is addressed in the permit. The upper Hubbard Creek disturbance consists of a graveled pad and a pond. This area may be left graveled at the request of the Forest Service as a parking lot for a trail head. SMC and the Forest Service are still negotiating on this. The disturbed area drains to a sedimentation pond. The main facilities area lies along a rail line and state road at the town of Somerset. For descriptive purposes, the site can be broken down into a few areas. Conveyor and Sanbom Creek portals -All this disturbance has an SAE. The sediment control measures consist of a berm and hay bales. The conveyor comes out of the portal and carries the coal over to the loadout area; it is about 4000' long. An access road parallels this conveyor to the portals. Along this road is the mine water discharge pond. Monitoring records show that the discharge has been acceptable.
