PERMIT #: M-1999-022 INSPECTOR'S INITIALS: SIM INSPECTION DATE: May 10, 2017 OBSERVATIONS This was a monitoring inspection of the Clayton Sand and Gravel Pit operated by Rodney Clayton, the Son of Eddie Clayton. Eddie Clayton has deceased. This site is located approximately 8 miles west of Center, Colorado in Saguache County. I, Stephanie Mitchell of the Colorado Division of Reclamation, Mining and Safety conducted the inspection. Mr. Rodney Clayton accompanied me on the inspection. This is a 3.90 acre 110c mining operation for sand and gravel. A mine identification sign was in place at the entrance to the mine site. The site is stable and no disturbance was observed outside of the approved permit boundaries. The permit area acreage has been reduced over the years through acreage release requests in 2003 and 2010. There was a stockpile of concrete on site. If not being used for the active mine operation, all debris must be legally removed from the site before July 18, 2017. The Operator has the option of burying the concrete portion of the material (Per Rule 3.1.5(9)) under the following criteria: An Operator may backfill structural fill material generated within the MLRB permitted area into an excavated pit within the permit area as provided for in the MLRB Permit. If an Operator intends to backfill inert structural fill generated outside of the approved permit area, it is the Operator's responsibility to provide the Office notice of any proposed backfill activity not identified in the approved Reclamation Plan. If the Office does not respond to the Operator's notice within thirty (30) days after receipt of such Notice by the Office, the Operator may proceed in accordance with the provisions of this Rule. The Operator shall maintain a Financial Warranty at all times adequate to cover the cost to stabilize and cover any exposed backfilled material. The Notice to the Office shall include but is not limited to: (a) a narrative that describes the approximate location of the proposed activity; (b) the approximate volume of inert material to be backfilled; (c) a signed affidavit certifying that the material is clean and inert, as defined in Rule 1.1(20); (d) the approximate dates the proposed activity will commence and end, however, such dates shall not be an enforceable condition; (e) an explanation of how the backfilled site will result in a post -mining configuration that is compatible with the approved post -mining land use; and (f) a general engineering plan stating how the material will be placed and stabilized in a manner to avoid unacceptable settling and voids. Topsoil is stockpiled throughout the mining area. In addition, little or no weeds appeared to exist on this site. No fuel was being stored at the mine site. It is recommended at this time that the Operator start to reclaim (grade remaining material stockpiles, spread remaining topsoil and seed area with the approved seed mix) the remaining disturbed area.
