~~ 2. The applicant depicts the areas to be quarried and affected on the mine plan map. The map does not contain a scale, so the Division is unable to determine the acreage associated with the mining activity. Please refer to the comments noted above for map/exhibit requirements. In addition, the applicant depicts affected area west of Steamboat Valley Road. [t is my understanding that land west of Steamboat Valley Road is a steep drainage (the general location of the pushed rocks 1. The applicant states that the practice of pushing rocks down the canyon into undisturbed land will not occur, but the map depicts a large affected west of Steamboat Valley road and clown the drainage. Please clarify this discrepancy and revise the maps accordingly. 3. The applicant states that reclamation will occur in stages as the quarry is depleted. Topsoil and overburden will be stoc}:piled on site to be used for final reclamation. If piles are stockpiled on site for greater than one year, a temporary seed mixture must be applied to protect the material from wind and water erosion. The Division recommends a temporary cover on stockpiled material and affected areas that can sustain the growth. The Division recommends a combination of 2-3 of the species noted below to be applied on the stockpiled material at a rate of 15 lbs./acre. • Western Wheatgrass • Smooth Bromegrass (or Mountain Brome) • Slender Wheatgrass • Sideoats Grama • Intermediate Wheatgrass Please include this temporazy seed mixture and practice in the application. 4. The applicant did not identify Steamboat Valley Road as a structure within 200 feet of the affected area. Rule 1.1(48) defines ";structure, Sienificant, Valuable and Permanent Man-made" as a non- portable improvement to real property which has defined, current and recognizable value of an economic nature; generally including but not limiting to: buildings, houses, barns, fences, above or below ground utilities, img~Rion ditches, maintained or pub/ic roads, bridges, railroad tracks, etc. The Division believes that Steamboat Valley Road meets the definition of permanent man-made features within 200 feet of the mine site. Where the mining operation will adversely affect the stability of any significant, valuable or permanent man-made structure located within 200 feet of the affected land, the applicant may either: • Provide a notarized ~igreement between the Applicant and the Person(s) having an interest in the s[n~cture, that the Applicant is to provide compensation for any damage to the swcture: or • Where such an agreement can not be reached, the Applicant shall provide an appropriate engineering evaluation that demonstrates that such structure shall not be damaged by activities occurring at the mining operation.
