Photo "2b" is a higher elevation view of the South Portal Facilities, looking to the northwest. The suspended coal conveyor over the river is visible in Ute photo. Photo" 2c' is another view of the South Portal Facilities, looking more directly to Ute noNt. Photo Se[ 3 Photo 3a is a view to [he northeast, covering the Roadside North Portal and associated surface facilities, which are located on the opposite side of Ure Colorado River from the South Pons] area, at Ute mouth of Coal Canyon. The linear water feature along the eastern edge of the area (right side of photo) is an irrigation canal. The large polygonal water feature west of the canal is an evaporation pond associated wiUr the Public Service Company Cameo Power Plant. The canal and Ute evaporation pond are not Powderhom Coal Company facilities. Immediately to the nonlt of the evaporation pond is the North Portal Coal Handling Area, which includes coal stockpile areas, conveyors, crushing and screening facilities, and a wck loadout swcture. There is a topsoil stockpile in the nonleast comer of Ute facility area, and a sediment pond (Pond 4) along the souUreast perimeter. Wlten it was operational, coal from the Roadside Nottlt mine was conveyed to this facility, loaded into wcks and hauled to the preparation plant at Ure South Portal area. Immediately west of the coal handling area is the mmp or decline which was excavated down to the North Portals, which have been sealed with din fill A vertical exhaust fan swcture and conveyor swaures are visible in the ponal decline. To the west of the decline is an electrical substation, two topsoil stockpiles and a constmction dirt stockpile. Aaoss the road to Ute south of the stockpiles are a triangular 2 ~' , ; shaped minewater treatment pond (no longer utilized) and a rectangular sediment pond (Pond 5). Across the road to the east of Pond 5 is the North Portal equipment storage yard. The linear drainage Ceature souUr of the facilities is the Coal Canyon drainage channel, an ephemeral drainage which runs southeast to the Colorado River. Total disturbance acreage associated with the North Portal and Surface Facilities is approximately 28.3 acres. Photo 3b is a view from the lower end of Coal Canyon down drainage toward the Colorado River, visible along Ute top of the photo. The Public Service Company (PSC) Cameo Power Plant and coal stockpile is in the upper right of the photo, wish the PSC evaporation pond and the Roadside North Portal Facilities in the upper left. Visible in the foreground on either side of the Coal Canyon drainage are PCC's refuse disposal areas, CRDA-1 on the right side of the photo and CRDA-2 on the left side of the photo. The segment of Coal Canyon drainage between the lower road crossing (just upstream from Pond 12) and the upper road crossing (located between CRDA-1 and CRDA-2) is a permanent sVeam channel diversion conswcled by Powderhorn Coal Company. The feature centered in Photo 3c is CRDA-1. The view is to the norU4 looking down on Ure top of the pile. The lower three benches of the pile have been covered tviUt soil and permanently revegetated. The upper benches have been rough graded, with final grading, topsoiling, and revegetation still to be done. Sediment Pond 6 is the dark, rectangulaz feature between the eastside [ce of the pile and the Coal Canyon Drainage r 3 penttanen[ diversion. A portico of CRDA-2, and Ute upper road crossing of Coal Canyon Drainage is 9. 6 visible in the upper right comer of the photo. The northeast trending drainage west of CRDA-1 is Coal Gulch An approved soil borrow area (CBA-2) is located to the west of Coal Gulch, and will be the source of soil cover material for CRDA-1 and CRDA-2 fatal reclamation. Total disturbance acreage associated with CRDA-1 is approximately 26 acres; CBA-2 disturbance acreage would total approximately 8.6 acres. Photo Set 4 CRDA-1 is in the lower left portion of Photo 4a, and CRDA-2 is in Ure upper right poniorr of 4a. The Coal Canyon permanent stream channel diversion segment extends from the upper road crossing of the Coal Canyon channel, near the center of 4a, to the lower crossing of Ure channel, visible on 4b. Certain modifications to the Coal Canyon permanent diversion segment were approved under Teclurical Revision
