Previously, water has been pumped from Pond 4A to 4C, prior <br />to use for dust suppression purposes. Removal of water from Pond 4A for dust suppression will <br />eliminate the need to routinely drain the water line between the ponds and minimize the potential <br />for the line to freeze. It will also allow the water line to be repaired when frozen, without <br />interfering with the removal of water for dust suppression. <br />Attached is a table that provides a comparison of the various parameter values from the most recent <br />analyses from Ponds 4A and 4C, as well as the data from Pond 4C included in your approval letter <br />dated April 12, 1995. A copy of the April 12, ]995 letter is also attached for your information. <br />The metals and total anunonia values for the samples collected in late 1998 from Ponds 4A and 4C <br />are very similar, and well below the Pond 4C values contained in your letter dated April 12, 1995. <br />The weak acid dissociable cyanide ("CNWAp") concentration for Pond 4A is higher than the values <br />reported for Pond 4C, but is still considerably lower than the 0.2 mg/1 standard for this parameter. <br />We would appreciate your prompt review of this information and written acknowledgment that the <br />use of water from Pond 4A for dust suppression is an acceptable practice. With this approval, <br />CC&V will continue to comply with the conditions specified in the April 12, 1995 letter. If you <br />have any questions, please do not hesitate to contact me at 719-689-4041. <br />Sincerely, <br />~~t ~.~~ <br />Scott A. Lewis <br />Manager, Environmental Affairs <br />Enclosures <br />
