Maest had been A final MOU and contract should be executed with initial third-party samplin~l occurring Staff briefly discussed the Board's two additional corrective actions, including reduction and maintenance of cyanide levels in the tailings ponds at interim cyanide levels. Cyanide levels in the active or lower tailing ponds have been reduced to about 4 ppm WAD. The inactive or upper tailings pond is at a range of about 0.4 ppm. Staff said TR-10 was approved on July 31, 1991, and the operator is proceeding with the construction for installation of the INCO process. Staff referenced an August 24, 1992 memo included in Exhibit A and addressed the issue of long term detoxification of the tailings in the pond. Staff said the matter should be addressed through the operator's ultimate compliance with abatement requirement no. 8, which states that this will be done 180 days after the ponds had been brought into compliance with permit cyanide standards. In reference to a request the Board had made previously, Staff presented a "draft" Interim Order Concerning Detoxificatioi and said the operator had indicated that the INCO process should be installed by the end of September and that the facility should be functioning in compliance at the spigot by mid-October. Therefore, in re~•ponse to a request from the Board, Staff said that, if necessary, the Division would recommend that November 30, 1992 be imposed as the date for the operator to bring cyanide levels into compliance with permitted standards. However, Staff explained that the Division's opinion is that the Board has given the Division the direction and aithority to supervise the operator's progress toward doing everything possible to achieve the lowest cyanide levels and compliance with permitted standards as fast as possible. Mr. Andre' Duchane, representing the operator, said the company would place a tank of hydrogen peroxide in the area of the collection pond, in order to further treat the pond and maintain reduced cyanide levels. Mr, Dean Massey, an attorney representing the operator, said the Staff's presentation accurately represented activities being conducted at the site. He said the operator is not satisfied that the order proposed by Staff is necessary, because of the continuing Board Order already in effect. Mr. Massey introduced the operator's new site manager, Ken Kluksdahl. Ms. Nora Jacquez, representing the Costilla County (:onservancy District, and Mr. Roger Flynn, representing the People's /alternative Energy Services of San Luis, addressed the Board briefly. Ms. Jane Kircher, another party, was also present. Mr. Flynn <aid their concerns relate to compliance of the collection pond, as well as setting a deadline for compliance to occur prior to a hard freeze. Ms. Jacquez discussed concerns regarding cyanide levels as it elates to flooding from heavy rains and community notification in these instances.
