Box 1298 RESOURCES Glenwood Springs, Co B1W2 JUN 2 4 p996 DiVj$ion of Minerals&UCOlogv June 20, 1996 Michael B- Long Director Division of Minerals & Geology Room 215 1313 Sherman St. Denver, CO 80203 RE: Mid-Continent Quarry- Carbondale Load-out/Warehouse Facility Dear Mr- Long.- I wish to update the Division miming the Mid-Continent Limestone Quarry and the Carbondale Loadout. I've attached for your information both memos and letter from Harlan & Associates, who have been asked to advise Mid-Continent on environmental matters. As indicated by Dick Harlan in his memo of June 13, 1996 the splits of samples collected by BLM at the quarry on May 2, 1996 were analyzed for PCB by Evergreen Analytical, a lab in Wheatridge, and found to be below detectable limits- An affidavit filed by EPA indicate: that EPA took samples of the stained soil in the quarry on May 22, 1996 and that lab results "-__ did not show the presence of any PCBs-" [page 12]. However, BLM's samples, tested by another lab, Enviro-Chem of Grand Junction, differ from the test results of the other labs. BLM has not released these test results, but a=rding to an affidavit filed by EPA, These written test results [of Environ- Chem] indicate that synthetic PCBs were detected in the soil at 54.12 parts per million (ppm), 13.98 pm and 14.71 ppm- ' [Page 101 As you know, EPA executed a search warrant of the Carbondale Ioadout facility and office on June 1, 1996. We have been attempting to obtain splits of the samples taken by EPA at that time, but had not been able to do so at the time of my last conversation with Harlan &Associates, on June 18, 1996.
