We have studied the proposal and wish to suggest some <br />modifications CC&V believes will make the procedures fit the site-specific circumstances. <br />We have developed some definitions and attempted to divide the Commitment into four <br />protocols, three of which address the physical monitoring (underdrain system, leak dection <br />system, and ground water system) and the fourth of which addresses <br />COMMITMENT <br />Definitions: <br />"Arequa Gulch Underdrain" refers to a drainage system comprised of 4 pipes and a rock drain <br />installed under the two phases of the Cresson Valley Leach Facility. The concenVations of <br />substances in this system may be determined individually or in combination at any location from <br />their exit from the Valley Leach Facility to the permitted area boundary. However, for <br />compliance purposes, should elevated levels of potential contaminants be indicated by <br />measurements of the system, the compliance point will be located at the location in Arequa <br />Gulch identified as "AG-01.5" at or inside the boundary of Permit M 80-244 unless CC&V <br />demonstrates to the satisfaction of the OMLR that the compliance point can be located elsewhere <br />for any specific set of circumstances. <br />"CNW,,p" refers to the weak acid dissociable component of the cyanide. Measurement is by an <br />
