Shelton <br />Director <br />November Z2, 1982 <br />TO: Sandy Emrich <br />FROM: Jerry Zimpfer ~~-! <br />RE: Foidel Creek Underground Mine, Surface Water Adequacy Review <br />(Rule 2.04.7 and 2.05.5(3)). <br />During the course of my adequacy review for alluvial valley floors, I have <br />identified a couple of additional concerns that should be addressed in the <br />surface hydrology section of the PAR. <br />1. Rule 2.04.7(4)(d) - The records of the State Engineer's Office list <br />several irrigation ditches on Fish Creek (KO11 Ditch, Mager Ditch, Boettler <br />Ditch 1st. Enl, and Corliss Ditch) and on Foidel Creek (Lieske Ditch) downstream <br />from the proposed mining operation. (See attachment.) The applicant should <br />revise Map I4 of the permit application to identify the point of diversion, and <br />the area of use. The applicant should also discuss the nature of use and the <br />status of the diversion. <br />2. Rule 2.05.6(3)(b)(iv) - On page 2 of my November 5th memo concerning the <br />adequacy of the surface water sections of the permit application I requested <br />that the applicant assess the effects of mine water and water from the spoil <br />dewatering well on the Foidel Creek/alluvial aquifer system. This assessment <br />should be carried downstream to the point that the changes in water quality <br />and quantity become insignificant, including assessment of the effects on <br />Middle Creek and Trout Creek if appropriate. <br />These concerns should be added to those in my November 5, 1982 memo. <br />/ys <br />cc: Ed Bischoff <br />Jim Pendleton <br />Dave Craig <br />Bob Liddle <br />
