BOX 928 <br />GOLDEN, COLORADO 80402-0928 <br />MAY 2 ~ tsss RECEIVED <br />Mr. Charles C. McKay <br />Church Ranch Corporation <br />10050 Wadsworth Blvd. <br />Westminster, Colorado 80024 <br />Dear Mr. McKay: <br />JUN 03 1999 <br />Division of Minerals & Geology <br />Your May l0, 1999, letter mentioned the building of a berm on the west side of the Lakewood <br />Brick and Tile permit area using commor, fill dirt. I have discussed this with the Department of <br />Energy Rocky Flats Field Office staff, and there are a couple of concerns that we would like to <br />discuss with you in a meeting next week if possible. We wonder with the installation of Buildings <br />60 and 61 if the 1986 requirement is still needed. Another area of concern is that the imported <br />material may introduce more weeds and that the area, because of its disturbed nature, may be <br />conducive to further weed invasion. <br />There is also a question concerning the physical location of the topsoil that was stockpiled at the <br />initial opening of the pit, and how much material, together with this original material, will be <br />required to reclaim the pit from now until the pit is closed. The quality of the material in the berm <br />(common fill dirt) does not seem conducive to immediate stabilization and revegetation on the <br />berm itself until it is used, and we are concerned that fugitive dust may be a problem with our air <br />monitoring program. As has a]ways been the case with this operation, we ask that truck traffic <br />entering through the west gate occur after the hours of major traffic for safety reasons. <br />The proposed meeting would include both the Department of Energy and our contractor staff. Carl <br />Mount, a Surface Reclamation Specialist from the Colorado Division of Geology and Minerals, has <br />been asked to attend as well. <br />The Department of Energy appreciates your notification of the activity and we look forwazd to <br />discussing this issue. <br />Sincerely, <br />Yohn J. R pe <br />Deputy ssistant. <br />for Environment <br />Infrastructure <br />
