ID~ DEC 22'93 835 No.002 P.03 <br />• <br />ability to efficiently conduct operations. We recogni.zc <br />that the Division will be short-handed by the holidays acid <br />scheduled vacations, and for this reason, BMRI suggest's that <br />the Division employ WWL to assist with the review of '1'7t-16 <br />to meet the January 4, 1994 decision date. <br />TR-17, pursuant to the Board's directive to resolve i.sisucr: <br />concerning process pipelines, was submitted at the reylue:;t: <br />of the Division as a mechanism to incorporate process water <br />pipeline specifications and maintenance procedures ir~t:~ our. <br />permit. BMRI is in agreement with the Division to extaend <br />the decision date for TA-17. BMRI believes that an <br />extension to February 1, 1994 will provide adequate review <br />time for forthcoming pipeline specification information. <br />Also, the extended review time of TR-17 should not intaerfere <br />with the orr-going reviews of TR-15 and TR-16; this will <br />allow staggered deadlines for the in-process technical <br />revisiOR6. <br />As a follow-up to BMRI's December 20, 1993 informational <br />telephone conversation with the Division, BMRI received t}ie <br />verbal approval for deposition of tailings across the <br />upstream face of the main embankment prior to a fins] <br />decision concerning in-tailings pie2ometers. Deposition <br />along the main embankment face is necessary to re-e~:i:,yblitll <br />routine spigot sequencing after the extended construction <br />project interruption. The Phase I main embankment .end litiar <br />system continues to be the containment structure at the <br />present elevation of the tailings. As previously committ.ecl, <br />AMRI will not place tailings on the Phase 7I liner until <br />final approval of the as-built report has been comp]etecl. <br />HMR7 will work diligently with the Division for a <br />final resolution of all outstanding issues concerniny <br />the San Luis Project. <br />If you have any questions, please call. <br />sincerely, <br />~.P~ ~ S ~~ <br />Alana L.
