P.O. Box 310 San Luis, CO 81152-0310 Re: Sou Luis Project, Permit No. M-SS-112 Deaz Ms. Hayes: STATE OF COLORADO \' / II~~~ DEPARTMENT OF NATURAL RESOURCES Roy Romer Governor lames 5 Lochhead Executive Director Michael B. LOng Division Director I finally have had an opportunity to review your correspondence dated July 10 and 11, 1995 regarding a few outstanding matters at the San Luis Mine. As you stated in your Judy 11, 1995 letter, the problem you have with the M-14 well will be resolved this month. When it is resolved, send me a letter outlining what was done to take care of the problem. Also, you stated that the size of the containment area for the make-up water tank overflow had to be reduced because of "the soft ground in the southwest comer." Please provide the Division with an as-built drawing of the final structure so an accurate document can be placed in the files. In your July 10, 1995 letter, you outlined the then current status of several outstanding items. There have been quite a few changes since July 10, including: (1) the Division's approval of TR-017 and conditional approval of TR-018, (2) your response to the M-14 monitoring well problem, (3) your submittal of TR-023 addressing the discontinuation of monitoring requirements for ten piezometers and the once-a-week sampling of the Inco tailings, and (4) your response to the spigot distance issue. The list of outstanding issues grows smaller every month. As you pointed out in pazagraph E of your July 10, 1995 letter, you will be submitt[ng an amendment (technical revision) to the permit changing the post-mining land use for the old office site. You indicated a concern about my request for water samples from the water wells at the site. The reason I suggested taking samples from the water wells is in regard to the requirement of Rule 3.1.7(8), which states, "An operator shall demonstrate, to the satisfaction of the Office, that reclamation has been achieved so that existing and reasonably potential future use of groundwater are protected." You may not be able to demonstrate protection of groundwater without sampling the water wells. If you can demonstrate that the groundwater was not adversely impacted from the heap leach operation without the water samples, then provide the information when you subn3it your release request.
