Avramenko and Holm: <br /> As you know, the Division of Minerals and Geology is in the <br /> process of accomplishing reclamation of the Coal Basin Mine in <br /> Pitkin County. Some of the reclamation to be accomplished during <br /> the next two construction seasons will occur in the facilities <br /> area. This area was the primary focus of the environmental audit <br /> conducted by Harlan and Associates (Harlan) this past summer. The <br /> Division of Minerals and Geology is interested in your comments <br /> regarding the findings and recommendations contained in the final <br /> report issued by Harlan and Associates on August 2, 1996. <br /> Given your Divisions' expertise in the area of hazardous waste, we <br /> request your assessment of the existing condition at Coal Basin <br /> before proceeding with the required reclamation projects in the <br /> facilities area. <br /> Our specific questions are as follows: <br /> In the August 2, 1996 memorandum, Harlan states that the soils <br /> proposed for disposal at the Conservation Services, Inc. (CSI) <br /> facility must be tested for RCRA characteristics to confirm that <br /> the material is not hazardous. What additional constituents should <br /> be sampled for the RCRA characterization, and, if any of the <br /> sampled constituents are found to be elevated, how and where would <br /> this material be disposed? <br /> In the August 2, 1996 memorandum, Harlan states that the material <br /> has not been fully characterized. What is your interpretation of <br /> this comment? Is this a reference to the RCRA characterization <br />
