Long <br />Division Dnenor <br />109; Aest Elk Mine; File No. C-80-007 <br />The Division has received Mountain Coal Company's modification to <br />Minor Revision No. 109, which approved installation of a berm in <br />MB-1 to facilitate lining of the pond. Enlarging the southern half <br />of MB-1 to 4.9 acre-feet and including an overflow relief valve <br />should ensure that the capacity of the pond will be maintained, <br />particularly during spring runoff. <br />Please call if you have any questions. <br />Sin~e~ely <br />Christine E. <br />Environments <br />on Specialist <br />CEJ/007MR109 <br />
