Site Reclamation Activity 4/94 - 3/95 Page 9 INTERPRETIVE SIGN AREA - Plate No. 3 This area is located just west of Boulder Creek and south (across Hwy. 110) from the toe of Tailings Pond #2. It was previously designated as a peat stockpile area but was converted to a parking and interpretive sign area (TR-017) . The interpretive signs feature historic and reclamation photographs with supporting text. The area not used for parking or sign area was seeded with the Mountain Mix at a rate of 22 lbs/acre and covered with hay mulch at a rate of 1 ton/acre. Activity planned for 1995 includes; 1) monitoring and maintenance. 2) installation of a chain fence to discourage access to the steep slopes on the south of the area. EUREKA STOCKPILE AREA This area was released from bonding and removed from the permitted area during 1994. BULKHEADS - TR-14 / TR-16 The construction of underground water retaining bulkheads, as approved by DMG, continued during the 1994 reporting year. At the end of the reporting year, five bulkheads of a six bulkhead program had been completed. Removal of the remaining equipment and other material (ie. grease and oil products, florescent lights, etc) was ongoing at the end of the report year . The required conjunctive flow study of Cement Creek was finalized and submitted to DMG. The results showed that measuring conjunctive flow was not significantly different than measuring Cement Creek flow at the MLR point CC-1. Therefore a request was made to accept surface flow measurements at CC-1 as representative of conjunctive flow. This request was approved by DMG. The mine water tracer inoculation program was eliminated as a requirement of TR-14 approval by DMG after concerns were raised by CDPHE that the tracer could be toxic and testing by SGC confirmed potential chronic reproductive effects on Ceriodaphnia at or near the proposed concentrations.
