March 28, 2011 C- 1981- 041/Roadside Portals MPB noted at any of the sediment pond locations. As requested during the last completed inspection, SCC has repaired the silt fence at the 2 -West portals (see attached Photo No. 2). Drainage and diversion ditches were stable with no significant erosion or other problems noted. ROADS — Rule 4.03 Construction 4.03.1(3)/4.03.2(3) Drainage 4.03.1(4)/4.03.2(4) Surfacing and Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) Reclamation 4.03.1(7)/4.03.2(7): Roads were mostly dry and well maintained in the locations west of the interstate including the North Portal, Unit Train Loadout (UTL), and refuse disposal areas. Roads were also in good condition at the North Decline and South Portal areas. Road ditches were in good condition and road culverts were all generally well maintained throughout the various mine site locations and support facility areas. Roads into the 2 -West Portal and South Fan site locations were muddy but we were able to access these locations. REVEGETATION — Rule 4.15 Vegetative Cover; Timing: Most of the large reclaimed areas at the Roadside Portals Mine exhibit an abundance of cheatgrass. This has become a widespread problem at several locations including the RSRDA by the South Portals (Photo No. 3), The CRDA -1 and 2 refuse piles, and at the North Decline reclaimed area (Photo No. 4). The problem is not limited to the reclamation in fact many of the surrounding areas along I -70 have the same problem and the vegetation reference areas also exhibit an abundance of cheatgrass. Herbicide treatment and interseeding were done in 2005- 07 in an attempt to reduce the dominance of cheatgrass. Despite repeated attempts, it appears at this time there is not sufficient technology to control the persistent invasion of cheatgrass. SCC has submitted Technical Revision No. 60. With TR -60 SCC is proposing to change the cover, production, diversity standards and sampling methods for the purposes of bond release in Tab 14 of the approved permit document. TR -60 is currently under review by the division. As part of this complete inspection, the vegetation reference areas were viewed. The shadscale reference area located above the access road to the South portals is shown in Photograph No. 5 and the greasewood reference area is shown in Photo No. 6. SUPPORT FACILITIES - Rule 4.04: The entire South Portal reclaimed area remains stable and in good condition. The Kokopelli fruit stand is not open for business yet. The South Portal area was well maintained and no problems were noted during this inspection. The reclamation throughout the South Portal area remains in very good condition. At the UTL loop area, Halliburton's Cameo Sand Storage Facility is fully operational. The Division issued its proposed decision and findings to fully approve the Phase I /IFIII bond release at the UTL loop area on 3/21/1 land the final decision is pending OSM concurrence.
