these are automated machines. Mr. Blunt imports and analyzes these records each month. The <br />records did not indicate the sensitivity of the seismographs. As a result, Mr. Blunt printed the <br />manufacturer specifications for the Instantel Minimate Plus and included them in the <br />seismograph record file during our inspection. <br />Mr. Blunt reinstalled both seismographs during our inspection. We noted that the microphone at <br />the Ott property is pointed slightly away from active mining operations. We discussed this and <br />the possibility that it may be a problem. Mr. Zuber followed up with OSMRE's blasting expert, <br />Ken Eltschlager, who indicated that it is sufficient as long as there are no obstructions. <br />Rule 4.08.5 requires mine operators to retain each blasting record for at least 3 years and to make <br />them available for inspection by the Division and by the public upon request. CCC had blasting <br />records dating back through 2009. This is significantly more than 3 years. Mine staff indicated <br />that they had not received public inquiries regarding blasting in the past 3 years. <br />All problems noted during this records review were minor and all were addressed before the <br />conclusion of this inspection. <br />Rule 4.11.4: Disposal of Noncoal Waste <br />This mine site is tidy and litter -free. Noncoal waste is disposed of properly and is not a problem <br />at the Colowyo Mine. <br />Rule 4.13: Contemporaneous Reclamation <br />CCC is constructing the South Taylor Tributary drainage channel, a continuation of the existing <br />downstream channel, this year. The majority of the earthwork in this area is completed and the <br />remaining work should be completed this summer. No equipment was in this area during our <br />inspection. Remaining work includes tying in edges to ensure continuity of regraded slopes, <br />replacing topsoil (CCC intends to live haul topsoil from the active pit advance), rock -lining the <br />channel, completion of the sump, and seeding. Although not yet completed, the sump at the base <br />of the regraded area is in place and functioning to detain runoff before it is discharged to the <br />downstream reclaimed channel (see photo 21605). We discussed the possibility of dewatering <br />the sump to ensure it has the capacity to detain additional runoff. Although the sump is not yet <br />completed to design standards, pumping or siphoning water from this location could help ensure <br />protection of downstream reaches in the event of a large precipitation event. <br />Vegetation is establishing on the 2014 East Pit Reclamation Block to varying degrees (see photo <br />21604). Muddy conditions precluded close examination of these areas; however we were able to <br />note good vegetative establishment on one slope and notably lesser establishment on an adjacent <br />slope that was reclaimed at the same time. CCC is aware of this differential vegetative <br />establishment and will reseed as necessary. <br />Rule 4.15.1: Revegetation General Requirements <br />A short (approximately 12 — 24") herbaceous plant with clustered yellow flowers is spreading in <br />riparian areas along Highway 13 near the Gulch A Pond (see photo 21606). This plant appears to <br />be in the mustard family, perhaps Barbarea Orthoceras, a.k.a. American Wintercress. Although <br />this is not a noxious weed in Moffat or Rio Blanco counties, it appears to be acting in a <br />6 1 Page <br />
