~ . ` <br />June 19, 1994. It is our engineering consultant's considered opinion that the granitic material <br />would be most suitable. <br />Therefore this letter requests expediti~llS approval of substitution of the granitic material <br />obtained from the area of the valley leach facility as the source for bedding and backfill for the <br />underdrain pipes. The specifications for this material (sieve size) given in the specifications <br />would remain the same. Again, the characteristics of this granitic material are described in our <br />letter to you of June 19, 1994 (Subject: "Cresson Project; Permit Number M-80-244: <br />Commitment Number '36' (Underdrain Material)" We would appreciate receiving your <br />decision by early the week of July 4 if at all possible. The need arises from the need to <br />determine where to locate a crushing and screening plant. <br />Please feel free to call with any questions. <br />tartlaway <br />Environmental Affairs <br />FILE: CC&VSTIP.N06 <br />
