1.2 Permit C-1981-028
<br />The Coors Energy Company (CEC) is permitted, by Permit C-1981-028, to conduct surface coal
<br />mining and reclamation operations at the Keenesburg Strip Mine. This mine is located on private
<br />lands in Weld County, Colorado, approximately 7 miles north of Keenesburg, Colorado, at the
<br />north end of an extension to Weld County Road 59. That portion of the Permit area where mining
<br />took place is located Sections 25 and 36, Township 3 North, Range 64 West of the 6th P.M.,
<br />Weld County, Colorado, in a tract of 571.56 acres, more or less. Mining was accomplished in
<br />two (the A and B) pits. An access road right of way and some topsand storage areas and
<br />vegetation plots are located in Sections 2 and 11, Township 2 North, and in Sections 25 and 36,
<br />Township 3 North, Range 64 West, of the 6~h P.M, Weld County, Colorado, and comprise, in
<br />aggregate, 40.94 acres more or less. The total permit area contains 612.5 acres, more or less.
<br />1.3 History
<br />The Permit was first issued on November 3, 1981. It was renewed as of November 3, 1986,
<br />November 3, 1991, November 3, 1996, and November 3, 2001. By a Technical Revision (TR) to
<br />the Permit in 1987 (TR-13), reclamation work has included the controlled disposal of flyash as a
<br />portion of the backfill of mine pits. Coal extraction operations ceased in December 1987
<br />(Findings, Permit Renewal Number 2, March 17, 1992) and operations at the site have been
<br />limited to reclamation since that time. By a Minor Revision (MR), the disposal of hard rock mine
<br />wastes was also permitted (MR-34, August 11, 1996) and a small amount placed in Pit B.
<br />Backfill of Pit A at the site was completed in September 1998, and placement of topsoil and
<br />initial seeding was accomplished in 1999 (1999 Annual Reclamation Report). The Permit
<br />Renewal of November 3, 2001 was for continuing reclamation of the site. Reclamation activities
<br />have, from the renewal to date, been the progressive backfill of Pit B with flyash, followed by
<br />placement of spoil and topsoil (topsand) cover, and seeding.
<br />Reclamation work remaining at the site includes the completion of Pit B backfill, demolition of
<br />remaining temporary facilities, grading, placement of topsoil and seeding.
