Crosby Division of Minerals and Geology 1313 Sherman St, Room 215 Denver, CO 80203 / / Subject: Cemex, Inc., Lyons Quarry, Permit No. M-1977-208, Request for Technical Revision / Dear Erica: This request for Technical Revision to the Lyons Quarry permit is submitted in response to Item No. 2 in the Division's Inspection Report, dated June 24, 2004. This item was described as follows: "Problem: Areas of the CEMEX Lyons Quarry have been reclaimed differently than what was approved in the original application and subsequent revisions to the permit (i.e. roads, highwalls and location of ponds). C.R.S. 34-32.5-116(4)(q) requires that final reclamation be completed within 5 years after the date that mining has been completed. Corrective Actions: CEMEX will need to reclaim the site as per the reclamation plan, or file a revision to the permit to reflect roads to remain on site, the retention of highwalls (or a variance of the 2h:1v/3h:1v) slope and the location of ponds by October 1, 2004." On September 17, 2004, the Division approved a deadline extension request to October 22, 2004. Pit A In 1984, Southwestern Portland Cement Company (a predecessor to Cemex) requested a Technical Revision to the reclamation plan for Pits A and B. In this TR, Southwestern requested approval to leave approximately 5,000 feet of vertical benches ('highwall') along the east and south sides of A-Pit Reservoir. The purpose of this request was to increase the water holding capacity of the reservoir. The Mined Land Reclamation Board approved this TR in September 1984, with a stipulation that the area not be used for recreation.
