Long <br />Drvisian Dneuor <br />RE: Technical Revision No. 007, Approval of Request to Continue Use of Hydrogen Peroxide, <br />Battle Mountain Gold, San Luis Project, File No. M-88-112 <br />Dear Ms. Scott: <br />On October 15, 1992 the Division received your letter requesting that Battle Mountain gold be <br />allowed to continue adding hydrogen peroxide to the tailings pond to maintain the cyahide <br />concentrations until start-up of the INCO circuit. <br />Technical Revision No. 007 states that the HRO, system shall not be used after October 15, 1992, <br />without the express written permission from the Division. From letters and phone conversations <br />with you and Ann Baldrige it is apparent to the Division that construction of the INCO SOZ <br />detoxification system is complete. You stated that on October 15th and various times since, you <br />have tested the water and electrical circuits and have discovered minor problems with leaks and <br />electrical malfunctions. The Division realizes that these kinds of problems are to be expected with <br />the start up of large complex systems. The Division appreciates your efforts in trying to reach your <br />goal of an October 15th start up. <br />On October 15, 1992, I gave Ken Kluksdahl permission by phone to continue the use of hydrogen <br />peroxide. I have been assured by you that the INCO system should be on line by November 15, <br />1992. The Division gives its permission for Battle Mountain Gold to continue the use of H,O, under <br />technical revision no. 007 until the INCO system is on line or until November 15, whidhever comes <br />first. <br />Sincerely, <br />i <br />Larry D.
