JSC, INC. <br />P.O. Box 1153 <br />Meeker, CO 81641 <br />Phone (970) 878-5292 Fax (970) 979-5392 <br />August 3, 2009 <br />Travis Marshall <br />Environmental Protection Specialist <br />Division of Reclamation, Mining and Safety - Grand Junction Field Office <br />101 S. 3rd St. STE: 301 <br />Grand Junction, CO 81501 <br />Travis, <br />I am writing in response to your comments concerning the Urie Gravel Pit in Rangely, CO dated July 31, <br />2009. Please see below for details on your individual comments/questions. Thank you for your effort in <br />this matter. <br />1. Mine plan states "No overburden or topsoil will be stockpiled along the river banks". <br />Please clarify the source of material for the proposed earthen sound barriers located along <br />the river and the northeast of the permit area. Also please state what reclamation methods <br />will be used to reclaim the sound barriers. <br />Response: As a condition of the Rio Blanco County Special Use Permit, Urie Rock Company is <br />required to construct an earthen sound barrier along the Easterly and Southerly portions of the <br />gravel pit. To comply with this condition, overburden will now be stockpiled along the Easterly <br />and Southerly portion of the gravel pit; this statement supersedes the previous statement in the <br />Mining Plan that no overburden would be stockpiled along the river. The overburden used to <br />construct these barriers will later be used to reclaim mining Phase III; the barrier areas will then <br />be reclaimed and revegetated per NRCS and DRMS recommendations. <br />2. Please state the total proposed surface area of the reclaimed pond and water depth. Also <br />clarify, in acres, the total area to be revegetated per phase. <br />Response: The remaining pond will be +/- 14 acres (surface area). The maximum pond depth <br />will be +/- 18 feet, with side slopes of 3:1. All areas of the former pit that will be less than 5 ft <br />underwater will be revegetated - we expect this will be approximately 2 acres per phase. This <br />area of revegetation is in addition to the disturbed areas outside the pit, which will be revegetated <br />after all mining is completed.
