(Page 2) <br />MINE ID # OR PROSPECTING ID # M-1977-436 <br />INSPECTION DATE 05/29/02 <br />INSPECTOR'S INITIALS ESC <br />This was an inspection of the Brighton Mine conducted by Erica Crosby of the Colorado <br />Division of Minerals & Geology. Connie Davis and Casey Jones of Aggregate Resources WCR, <br />Inc. were present during the inspection, <br />The purpose of the inspection was to inspect areas associated with Permit Amendment 002 ("AM- <br />02^). AM-02 was submitted by the operator as a result of the Division's inspection of <br />November 9, 2001 noting instability along pit slopes adjacent to the South Platte River. In <br />particular, the Northern Pit is within 65 feet of the South Pit River. River water seeping <br />into the pit has created instability in the pit slopes in terms of slumps and slides. The <br />operator proposes to construct a spillway to allow floodwaters to enter and leave the pit. <br />The new postmining land use will be reclaimed to wetland habitat. <br />The spillway designs are consistent with the requirement of the Technical Guidelines of the <br />Urban Drainage and Flood Control District. The operator is currently working with Urban <br />Drainage, Adams County and the Division to ensure all parties are agreeable to the spillway <br />designs. In addition, the operator proposes two spillways in the southern pit to allow mining <br />closer than 400 feet to the South Platte River. The Amendment is currently under review, and <br />there are no formal objectors to the application. <br />I & E Coatact Address <br /> ^ CE <br />NAME Connie Davis ^ BL <br />OPERATOR Aggregate Industries ^ FS <br />STREET P.O.
