PiAeda <br />Walden, Colorado 80430-8020 Director <br />Re: Van Valkenburg Gravel Pit, File No. M-20OS-003 <br />Request for Corrective Action Extension - Boundary Markers <br />Dear Mr. Van Valkenburg: <br />The Division of Reclamation, Mining and Safety (Division) has received and approved your letter requesting an <br />extension to the corrective action date to install permit boundary markers in concrete. <br />The new corrective action due date Is May 1, 2011. <br />In your letter you stated, the pit area was surveyed earlier and later affirmed by Lafarge with a GPS <br />instrument that the markers were up and correct. Please note the Division was unable to observe the <br />northern and northeastern boundary markers-'during the July 20, 2010 and November 11, 2010 inspections. <br />Rule 3.1.12 requires the boundaries of the affected area to be marked by monuments or other markers that <br />are clearly visible and adequate to delineate such boundaries. The Division expects the entire permit <br />boundary to be marked correctly by the extended corrective action due date. <br />I am sorry for the scheduling error which occurred during the last inspection. I was delayed by another <br />inspection and did not realize you intended to accompany me during the inspection. <br />A copy of a NRCS seed mix dated 10/25/10 was attached with your letter to the Division. <br />to revise the reclamation sed.mixlcrfox tlre<s fixture as a technical <br />?t <br />revision to the permit, per Rule 1. 9, with t, - ka4W-mf 1r1,jfL,*1r: istftachecl1fs m. <br />If you have any questions, please do not hesitate to call me at (303) 866-3567 Ext. 8124. <br />Sincerely, <br />/-V V- -0 ??/' - - - <br />Peter S.
