III IIIIIIIIIIIII III 999 `~ STATE OF COLORADO DIVISION OF MINERALS AND GEOLOGY Department of Narural Resources 131 7 Sherman 51., Room 215 Denver, Colorado 80203 Phone: (303) 866-3567 FAX: (303) 832-8106 October 18, 1994 Mr. Terry S. Haugen Public Works Director City of Trinidad P. O. Box 880 Trinidad, CO 81082 Re: Reclamation of Linden Avenue Railroad Loadout, Trinidad Basin Mining Company, Revoked Permit No. C-81-048 Dear Mr. Haugen: ~~~~~ DEPARTMENT OI NATURAI RESOURCE' Roy Romer Governor lames 5. Lochhead Executive Director Michael B. Long Division Di~eao~ Thank you for your letter of September 15, 1994. We appreciate your response, and would like to take this opportunity to discuss a few final items. With regard to your request for testing of the creosote content and acid generation potential of the coal at the Loadout, we agree to add these items to the list of constituents to be analyzed. We would, however, like to request the City consider reviewing the results of a single five-location composite sample only, for the purpose of verifying the presence of hazardous waste, rather than the results from both a single five-location composite sample and the results from five additional single-site samples. The reason we ask this is that the analysis cost per sample, including the creosote and acid generation potential tests, is estimated by our contact at the analysis lab to be about $750 per sample. To conduct the six-sample (one composite sample & five single-site samples) testing scenario requested by the City would result in a total analysis cost of approximately $4,500. By testing only the composite sample, we hope to reduce our analysis costs to $750, and spend the remaining money for the actual removal of the coal to the City's landfill, and the regrading and reseeding of the railroad area. With regard to the request for promixate and free swelling index analyses, we could pay for these additional tests if the City would agree to reviewing the results from a single composite sample. It is my understanding from the analysis lab that the additional cost for both the proximate and swelling index tests would be approximately $150.00 per sample. Again, testing a single sample would reduce our analysis costs and let more funds be used for the actual reclamation of the site.
