MANAGEMENT RECEIVED FEB 22 2001 Division of Minerals 8 Geolo!^~ Please accept this letter as the 2000 Annual Hydrologic Report for the Coal Ridge No. 1 Mine. This report is for the 2000 calendar year. The Coal Ridge No. 1 Mine was reclaimed during 1994. Until the mine was reclaimed, eight wells were monitored (LO-1, OW-3L, OW-7, OW-8, OW-12, OW-13, OW-14 & OW- 15). The groundwater monitoring wells were reclaimed late in 1994 and early in 1995. No groundwater monitoring was performed or required during 2000 (reference table 4.6-1 page 4-85}. The monitoring program includes the requirements of Colorado Discharge Permit System Industrial General Permit Facility Number COG-850005 (CDPS Permit). Copies of Quarterly Discharge Monitoring Reports have been provided, under separate cover, to the Division at the same schedule required by the CDPS Permit. They are included in this report by reference. There was no discharge from the sediment pond during the year. The Operator irrigated the crop land portion of the reclaimed mine site during 2000. Most of the excess irrigation water was contained in the sediment pond and used to water livestock. Consumptive use of water during the year included that used for irrigation and watering livestock. No accounting of water consumption is available. Please call if you have any questions. Sincerely, f J. E. Stover, P.E. Consulting Engineer
