Dept. o~ M31ural Reso~~rce~ <br />1313 Sherman St. - Room 423 <br />Denver, Colorado 80203 <br />SUBJECT: Fruita Mines - File #C-015-81 <br />Request for Reduction in Frequency of Surface and Groundwater <br />monitoring, regarding the Salt Wash, Coal Gulch; Groundwater <br />Monitoring Wells CM-l thru CM-4, CM-7 and Shallow Monitoring <br />Wells M-1 thru M-3. <br />Dear Brian: <br />Dorchester Coal Company obtained groundwater monitoring data on the subject <br />monitoring wells since October of 1980 to the present time. Samples and <br />water levels from groundwater wells and surface water samples and flows were <br />obtained on a monthly basis when access to the monitoring area was possible. <br />Monthly analyses of the collected samples was completed by Soltesco and <br />included tests for Ph, EC, DS, SS, Fe, and Mn. Quarterly analyses of the <br />samples was completed by Grand Junction Laboratory and consisted of 35 <br />tests required by CMLR. <br />Based on the amount of collected data and the inaccessability to the monitoring <br />wells during the winter months, Dorchester Coal Company requests that monitoring <br />frequency be reduced to semi-annual monitoring taking place in May and October <br />of each year. Also, when you receive Dorchester Coal's response to your 1981 <br />adequacy letter concerning Dorchester Coal's 1981 CMLR permit application, <br />Dorchester Coal will request that several of the 35 analyses required by CMLR <br />be omitted. <br />If you need a copy of our current water monitoring data for your determination <br />of monitoring frequency, please let me know. <br />Sincerely, <br />1 ~; <br />t• <br />Darrel Hespe <br />Environmental Coordinator <br />DHH:jp <br />Dorchester Coal Compa, <br />Colorado Operations <br />2795 Skyline Court <br />Grand function, CO 81501 <br />(303) 245-6370 <br />A Cu b~i~han' nl Dnrrh r~hv C.ac Cnrp~vati~n <br />
