~ ~ III IIIIIIIIIIIII III <br />xeow <br />Sanborn Creek Mine <br />May 15, 1997 <br />RECEIVED <br />MAY 21 1997 <br />William J. Carter <br />Environmental Protection Specialist <br />State of Colorado <br />Division of Minerals and Geology <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />Re: Demolition of Shop <br />Minor Revision Number 37 <br />Permit No. C-S1-022 <br />Division of Hunerals ~ Ueology <br />Dear Mr. Carter: <br />During your site inspection yesterday, we had a lengthy discussion <br />regarding demolition of the shop building and the potential for, <br />and evaluation of, the presence of hazardous materials. I am very <br />concerned with your expectations for the scope of work required for <br />this evaluation. <br />When we informed the Division of our plans to relocate the office, <br />shop, and warehouse with the submittal of Minor Revision Number 37 <br />on August 12, 1996, the Division responded on September 19, 1996 <br />with a concern for hazardous contamination on the site. We agreed <br />to put some appropriate language in the permit for testing and <br />evaluation of hazardous materials with our submittal on October 3, <br />1996. The minor revision was approved by the Division on October <br />25, 1996. <br />Since by that time, it was obviously too late in the construction <br />season to begin work, the project has been delayed to incorporate <br />it as part of the contract for the surface coal handling <br />modifications, currently pending approval as Technical Revision <br />Number 29. However, relocation of the office, shop, and warehouse <br />remains as one of the first items of work to be accomplished. Our <br />current schedule requires construction to start on the new <br />buildings as soon as the contractor mobilizes on site, probably in <br />August, assuming a timely approval of Technical Revision Number 29. <br />Demolition of the existing structures is scheduled following <br />construction of the new structures, probably in October or <br />November. During our discussion yesterday, I proposed to complete <br />the testing and evaluation of hazardous materials during the <br />geotechnical investigation to be completed this month. <br />P O B o x 5 3 5 S o m e r s e t C o l o r a d o 8 1 4 3 4 U S A <br />TEL (970)929-5122 FAX (970)929-5177 <br />
