III. COMMENTS-COMPLIANCE <br /> Below are comments on the inspection. The comments include discussion of observations made during the <br /> inspection. Comments also describe any enforcement actions taken during the inspection and the facts or <br /> evidence supporting the enforcement action. <br /> industrial/commercial. Thus in accordance with 4.15.10(3) the vegetation requirement of <br /> 4.15.10(2) may be waived if requested in writing by the landowner, and if the Division <br /> determines that revegetation is not necessary to control erosion. Although the premining and <br /> postmining land uses were both industrial, the revegetation requirement was not waived. <br /> Revegetation was established and according to Tonya Hammond of SCC topsoil was also <br /> redistributed at the site. SCC's reclamation contractor obtained topsoil from Topsoil Stockpile <br /> Number 4. Prior to redistribution the top four to six inches of the regraded surface was scarified <br /> to relieve compaction and provide for root penetration. Topsoil was redistributed on the <br /> conveyor corridor to a depth of six inches. The site was vegetated utilizing the approved seed <br /> mixture by hydro seeding or broadcast seeding at a rate of 15.7 pounds of pure live seed per acre. <br /> Certified weed free mulch was then applied at the rate of 4,000 pounds per acre. The straw was <br /> crimped with a serrated disc or other appropriate equipment. The entire conveyor corridor was <br /> successfully revegetated with exception of the Xcel service road crossing and small compacted <br /> area with gravel used for vehicle access or turnout area. <br /> During the inspection, participants walked through the entire reclaimed conveyor corridor to <br /> allow for visual assessment of compliance with the pertinent requirements described above. The <br /> DRMS also inspected the area qualitatively for revegetation success, erosional features and "bare <br /> areas", functioning of the reclaimed land to serve the post-mining land use, and completion of all <br /> reclamation obligations. The bond release application included an exhibit"Bond Exhibit SL-5" <br /> which shows the 2.1 acres nominated for bond release. This figure is included with this <br /> inspection report as Attachment 1. <br /> Revegetation Evaluation for Overland Conveyor area Final Bond Release <br /> Establishment of revegetation along the reclaimed conveyor corridor between former Transfer <br /> Point#2 and the Coal Canyon Public access road west of the Colorado River was evaluated <br /> pursuant to the requirement of Rule 4.15.10(2). Observations verified that ground cover of <br /> living plants was adequate to control erosion. See Photograph Numbers 1-5 at the end of this <br /> inspection report, which show adequately revegetated and stable ground conditions. No <br /> evidence of rills, gullies, or sheet wash erosion was observed along the reclaimed corridor. <br /> Vegetation cover was dominated by an overstory of fourwing saltbush with a lesser component <br /> of greasewood,big sagebrush, and rubber rabbitbrush, with an understory dominated by annual <br /> brome(typical for the general area), and various seeded grasses including alkali sacaton, needle <br /> &thread, and western wheatgrass. Various noxious species are present in areas adjacent to the <br /> reclaimed corridor, including tamarisk, whitetop, and Russian knapweed. These species have <br /> been sprayed on the disturbed and adjacent area in recent years by the operator, and have been <br />
