PERMIT #: M- 1977 -459 <br />INSPECTOR'S INITIALS: DMC <br />INSPECTION DATE: June 17, 2011 <br />OBSERVATIONS <br />This inspection was conducted as part of the Division of Reclamation, Mining and Safety's (Division) normal <br />monitoring program. Michael Irwin and Ty Stultz, representing the Operator, were present during this <br />inspection. Photographs are included at the end of this report in order to illustrate some of the conditions <br />observed during this inspection. <br />The Lake County Gravel Pit is located approximately 1.8 miles southwest of Leadville and accessed from CR 23. <br />The site is a 112c operation that includes a total of 55.97 permitted acres. The permit for this site was <br />converted from a 110c permit on April 28, 2000, adding 50.07 acres to the already permitted 5.9 acres. <br />Pursuant to Rule 4.1.2(2), no Financial Warranty is required for this site. <br />Adequate mine identification signage was noted at the entrance to the site in accordance with Rule 3.1.12(1). <br />The boundary of the affected area was marked by red, steel posts that were clearly visible and adequate to <br />delineate the affected area in accordance with Rule 3.1.12(2). <br />An asphalt stockpile was noted near the access road, on the south side of the disturbed area. The Operator <br />representative stated that asphalt recycling occurs at the site. These operations are not currently included in <br />the approved Reclamation Permit. Continuance of asphalt recycling operations will require the Operator to <br />submit a Technical Revision to the Division in order to revise the current permit to include asphalt recycling <br />operations. The technical revision must state the anticipated maximum amount of unprocessed asphalt that <br />will exist on -site at any one time. <br />It was noted during this inspection that very little native topsoil exists at the site, and that importation of <br />topsoil generated off -site will be necessary in order for the Operator to comply with the approved <br />Reclamation Plan, which requires topsoil to be distributed over the disturbed area to a depth of six inches. <br />The Operator imports topsoil from outside sources in the vicinity, such as new road construction projects, <br />when it is available. An imported- topsoil stockpile was noted west of the active area, north of the access road. <br />The active mine area is in the north portion of the permitted area. Mined slopes are maintained at near <br />3H:1V. Native topsoil stockpiles are located at various locations around the pit perimeter. <br />A crushing /screening facility was located on site. <br />A diesel storage tank was noted onsite that had been placed inside an unlined, bermed containment area. All <br />storage tanks, petroleum and any hazardous materials stored on site for any period of time shall have <br />appropriate secondary containment consisting of an impermeable containment structure with a capacity to <br />contain all contents of the tanks and /or various containers (when full) plus 10% of their total capacity. <br />No other problems or violations were noted during this inspection. <br />Responses to this inspection report should be directed to Dustin Czapla at the Division of Reclamation, Mining <br />and Safety, Grand Junction Field Office, 101 South 3rd Street, Room 301, Grand Junction, Colorado 81501, <br />phone number (970) 243 -6299. <br />Page 2 of 3 <br />
