Watcher <br />Executive Director <br />Ronald W. Cattany <br />Division Director <br />I completed an initial review of the subject AHR's back in April 2003. I forwarded a copy of'atural Resource Trustee <br />the initial review memo to the operator, and requested that the data tables for the 2002 <br />AHR be amended to include baseline data as specified in the permits. I wanted to receive <br />the updated tables before I requested the PHC review by a hydrologist. I just realized earlier <br />today that I had never received the updated tables, and so we had not completed our <br />review of the AHR's. I notified Jim Stover of this this morning, and he submitted copies of <br />updated tables with baseline information. <br />I'm not sure if the data he provided is sufficient to allow for meaningful comparison. <br />However, I would like to get this review finalized. So, I am officially requesting that you <br />forward my request for PHC review of the McClane and Munger 2001 and 2002 AHR's to <br />the staff hydrologist of your choosing. <br />Attached is my April 25, 2003 preliminary review memo, and also the amended tables I <br />today received from Jim Stover. If the reviewing hydrologist feels that additional baseline <br />data needs to be included in the data tables, I would request that they take a look at the <br />referenced baseline data tables in Volume 1 of the McClane and Munger permits, and advise <br />regarding the extent of data that needs to be included. <br />Please forward this memo, the attached memo, and the attached amended data tables to <br />the hydrologist. There should be hard copies of the AHR's in the Denver office, and the <br />AHR's have also been imaged. <br />Thanks. <br />Office of Office of Colorado <br />Mined Land Reclamation Active and Inactive Mines Geological Survey <br />
