ability to efficiently conduct operations. We recognize that the Division will be short-handed by the holidays and scheduled vacations, and for this reason, BMRI suggests that the Division employ WWL to assist with the review of TR-16 to meet the January 4, 1994 decision date. TR-17, pursuant to the Board's directive to resolve issues concerning process pipelines, was submitted at the request of the Division as a mechanism to incorporate process water pipeline specifications and maintenance procedures into our permit. BMRI is in agreement with the Division to extend the decision date for TR-17. BMRI believes that an extension to February 1, 1994 will provide adequate review time for forthcoming pipeline specification information. Also, the extended review time of TR-17 should not interfere with the on-going reviews of TR-15 and TR-16; this will allow staggered deadlines for the in-process technical revisions. As a follow-up to BMRI's December 20, 1993 informational telephone conversation with the Division, BMRI received the verbal approval for deposition of tailings across the upstream face of the main embankment prior to a final decision concerning in-tailings piezometers. Deposition along the main embankment face is necessary to re-establish routine spigot sequencing after the extended construction project interruption. The Phase I main embankment and liner system continues to be the containment structure at the present elevation of the tailings. As previously committed, BMRI will not place tailings on the Phase II liner until final approval of the as-built report has been completed. BMRI will work diligently with the Division for a final resolution of all outstanding issues concerning the San Luis Project. If you have any questions, please call. Sincerely, ~~a S~t- Alana L.
