.. <br />slurry wall will be necessary <br /> <br />The Board cannot wait for two <br />years while additional data is collected, when Battle Mountain <br />will already have begun to dewater the Rito Seco. <br />2. Battle Mountain Has Failed To Demonstrate That <br />There Will Be No Acid Generation. <br />In Point Nos. 9, 10, and 21-24, the MLRD repeatedly <br />expressed its concern over the potential for sulfuric acid <br />generation from the waste rock and tailings piles. The basis for <br />concern is Battle Mountain's data which indicates a pH level of <br />3.01 on combined tailings and waste rock material, and eight <br />weekly humidity cell tests, the results of which suggested to <br />MLRD staff an acid generation potential. In its response, Battle <br />Mountain blamed the 3.01 acid pH on laboratory error; however, it <br />failed to submit any evidence of pH neutrality. Likewise, Battle <br />Mountain disputed MLRD's conclusion based on the humidity cell <br />tests, but again provided no contradictory evidence. <br />3. Battle Mountain Has Failed To Provide Mill Facility <br />Design Specifications. <br />In Point No. 14, the MLRD requested that Battle <br />Mountain specify mill facility design information including sump <br />locations, material and height of knee walls, and the flooring <br />materials to address whether milling reagents would be contained <br />inside the milling facilities. Milling reagents spilled on the <br />-7- <br />
