City of Gol ~ 1445 Tenth Street, Golden, Colorado 80401 Telephone: 303/384-8151 Facsimile: 3031384-8161 www.ci.golden.co.us August 31, 2004 Mr. Thomas A. Schreiner Division of Minerals and Geology 1313 Sherman Street, Room 215 Denver, CO 80203 RE: Review Comments and Objections -Empire Pit, Permit No. M-1977-534, Amendment No. 2 ~a.; !t3-~"v~ Jq~-3- Dear Mr. Schreiner: Thank you for the opportunity to review and respond to the comments received by the Division regazding the above referenced permit amendment application. The City of Golden's outside Counsel, Don Ostrander of Duncan, Ostrander, & Dingess, is preparing a response to the objections raised by Amanda Bradley of Hale, Hackstaff, Friesen. This response will be submitted to the Division separately. This letter will address the concerns regarding fugitive dust control at the site. T'he City of Golden constructed the Guanella Reservoir at the site of the Empire Pit in 2003 and 2004. During construction, approximately 750,000 cubic yazds of gravel reserve remaining at the pit were excavated and stockpiled on-site. The construction and stockpiling effort was completed on January 23, 2004. Once construction was complete, Golden contracted to have the stockpile stabilized using a hydro-mulch, seed, and tacifier. This application was scheduled to begin on February 2, 2004, but was delayed due to weather until Mazch 2004. The hydro-mulching effort was, unfortunately, largely ineffective, due to the steep slopes of the stockpile. In Mazch 2004, Golden met with representatives of Cleaz Creek County and the Town of Empire to discuss their concerns with the stockpile. During that meeting, Golden committed to regrading portions of the pile to reduce visual impacts of the pile and with the hope that some of the wind effects could be reduced. In addition, Golden committed to stabilize the stockpile by applying a surface ratifier. In June 2004 the pile was re-graded. The east end of the stockpile, which had been the highest point, was lowered to match the grade of the middle and the entire top was flattened.
