Curango.Fleld Off" <br /> Dear Mr. Erickson: A,,o Division of Mirwais&Geology <br /> Sunnyside Gold Corporation has submitted three projects for inclusion as`B List" projects under <br /> the voluntary Consent Decree agreement with the Colorado Department of Public Health and <br /> Environment (CDPHE) for the purpose of benefitting water quality in the Animas River. The <br /> work plans for these projects are included for your review. Each of these projects involve MLR <br /> permit area at the Mayflower Mill and Tailings Facility. Therefore, this submittal is a request for <br /> a Technical Revision (TR-21) to MLR Permit M-77-378 for the elements of these work plans that <br /> are within the MLR permit area and are not maintenance items. A check for the review fee is <br /> attached. <br /> Each project is discussed below with the elements pertaining to work within the MLR permit <br /> area. Work outside the permit area will be performed under Sunnyside's facility Stormwater <br /> Permit (COR-040054) and the Consent Decree. <br /> MINING PLAN <br /> Mayflower Facility - Upland Hydrological Control <br /> The concept behind this project is based on observations by Sunnyside that runoff water in surface <br /> drainage channels up-gradient from Sunnyside's MLR permit area and facility is going subsurface <br /> before it can be intercepted and diverted by stormwater diversions within the facility. Preventing <br /> this from occurring will reduce the potential for water quality impacts from contact of flowing <br /> water with mine waste and tailings. Three drainages in the Tailings Pond No. 1 and Mayflower <br />
