I wish I had a good excuse,but the truth is that the submittal got lost on my desk. <br /> The purpose of this letter is to approve the lining of the above referenced gravel pit This approval <br /> is based on the information you provided under cover letters dated May 12, 2006 and September <br /> 29, 2006 as well as the site inspection conducted on May 3, 2006. The estimated pit inflows from <br /> precipitation and groundwater and outflows due to pumping and evaporation indicate that this nit <br /> has been lined to the desitan standard referenced in the August 1999 State Engineer <br /> Guidelines for Lining C titeria for Gravel Pits. Meeting the design standard requires that all <br /> water inflows and outflows for this pond must be accounted for on a monthly basis. <br /> Please call me if you have any questions. <br /> Sincerely,&* <br /> David L. Nettles, P.E. <br /> Assistant Division Engineer <br /> ShoresPitALineOK.doc <br /> CC: Scott Edgar,Water Commissioner <br /> Jeff Deatherage, Denver SEO <br />
