MINE ID # OR PROSPECTING ID#: M-1977-141 PAGE: 3 <br />INSPECTION DATE: 1-11-10 INSPECTOR'S INITIALS: ACS <br />determined that effective best management practices for storm water <br />have been installed and are being maintained at this quarry. It is to <br />be expected that South St. Vrain Creek carries a substantial sediment <br />load during and following rain events, but little or no sediment is <br />being contributed from the affected land of the quarry. <br />The quarry was inactive at the time of this inspection. The operator <br />reports that the only activities in 2009 were maintenance and hauling <br />approximately 1200 tons out of stockpile. The quarry was in full <br />production in 2008. The operator has no firm schedule at this time for <br />resumption of production. Therefore, the Division will require that <br />the operator file a notice of temporary cessation under Rule 1.13 of <br />the Mineral Rules and Regulations (2 CCR 407-4). The Notice must be <br />retroactive to January 1, 2009. See PB-2 on page four of this report. <br />The operator may continue to haul out of stockpile and conduct other <br />quarry activities while under temporary cessation. The requirement for <br />temporary cessation notice is to toll the time until commencement of <br />full reclamation is required or full scale production resumes. <br />The entrance sign at the quarry does not meet the requirements of Rule <br />3.1.12 in that it does not display the name of the operator nor the <br />correct mined land reclamation permit number. A correct sign must be <br />installed. See PB-3 on page four of this report. <br />cc: Kathy Rosow, Water Quality Control Division (via email) <br />Larry Quinn (via email) <br />Inspection & Enforcement Contact Address <br />NAME Connie Davis <br />OPERATOR Aggregate Industries - WCR, Inc. <br />STREET 1707 Cole Blvd., Suite 100 <br />CITY/STATE/ZIP Golden, CO 80401
