FROM~HOMESTRKE GOLDEN, CO~ TO~CO MINED LRND REC'L ~. DRAFT Mr, Allen C. Sorenson Colorado Department of Natural Resources Mined Land Reclamation Division 1313 Sherman Street, Rur. 215 Denver, CO 80203 30, 1992 9~29AM 25222 P.06 Reference: Minerals Program Inspection Report for "Bu11dQg Mine" June 8. 1992 Dear Mr. Sorenson: We are in receipt of the subject inspection report. On the last page of that report one item was noted as a "problem." We wish to provide the following information in response to that item. This letter is to be considered as the requisite "corrective" action that the report indicates should be achieved by August 7, 1992. The "probletn" listed has to do with the water-quality information for the area downgradient of the Lower Tailings facility, whether it is currently on file with the MLRD. For information purposes, we are enclosing a spreadsheet that contains all of the chemical and physical data that were required to be collected over the period of the NPDF.S permit condition. We need to clarify that the permit condition requiring ground-water quality monitoring dnwngrariient of the Lower Tailing Impoundment was a condition of the NPDES (Department of Health) pennit. A]I reporting was to the Water Quality Control Division. ]t was ~, to our knowledge, a condition of the MLRD/MLRB reclamation permit. The requirement was removed from the NPDES perntit when that permit was renewed a few years ago. The WQCD agreed that there were no longer any impacts that were attributable to the tailings impoundment in its current state. The collection and reporting was terminated when the permit condition was removed. I hope that the Division agrees that the monitoring was properly completed based on the data that have been generated. Should any questions arise, please call me as soon as possible. Sincerely, John E. Hardaway Technical Manager Environmental Affairs
