Access to the site will be by <br />an existing light-use road constructed in 1997. Because the depth of the well is relatively shallow (400 feet) <br />and the direction is oriented vertically, a small mudpit will need to be constructed. The mudpit designs, would <br />most likely be fora 0.5 acre pad as previously submitted in Technical Revision No. 101, (TR-101). <br />MCC is submitting to the Division a corrected Map 53B and a typical 25 Panel MDW Well Design in order for <br />the CDRMS to approve Minor Revision No. 343. The previously submitted Plugging and Abandonment Figure <br />did not change. <br />If you have questions regarding these adequacy responses for the minor revision please call me at (970) 929- <br />2238. <br />...................j...~.........................................................._ <br />L6~~'rc'1~.~-C <br />enry B e <br />Environmental Engineer <br />cc: P.
