'96 DMG rectives certification of tailings pond liner repairs from Colorado Lining Company 27 Feb. '96 DMG (A. Sorenson) completes a technical analysis showing "...(T)hat the Gold Hill Mil! water storage capadties may be exceeded as a result of relatively modest irtaeases in the rate of ground water inflows to the Haul A edit. " The report further states that, "lt is the Division's position that coatingenry measures need to be etracted to prevent unpermitted discharges from either the Hazel-A edit or the tailing pond, and that these contingency measures masrt be enacted in preparation for this year's Spring runoff. ... (1)t was agreed that COM, Inc, would proride a progress report on the development of cmdingeacy measures and implementation timeframes no later than March 4, 1996.' 2"1 Feb. '96 DMG (M.

Sorenson) to Mr. Richard Fox acknowledging receipt of a tailings pond water evaporation rystem design and indicating that such a system needs to be installed ASAP, with a target date of April I, 1996. Letter imposes certain technical requirements, incinding full containment of the spney within the lined pond era, and location of the pump intake within a geotatile-fihered sump. It further requests a proposal far additional contingency measures allowing for removal of additional water. Note: Actual performance of this rystem has been spotty at best. with occasional spray drift out-of-bounds, loug periods of non-operation despite repeated DMG admonitions/directions that pond is to be kept as near dry as practicable, and numerous occtarences of technical problems, especially clogging of spray heads, Probably due to intake of trash solids through the unfiltered pump. Presently (3 Sept. '97) existing installation probably cannot handle the design flow rates at the spray heads; dirett operation from the kazel A pump, such a3 has been rrcent practice, does not even come close.
