ASPHALT SPECIALTIES CO. 10100 Dallas St. Henderson, CO 80640 October 16, 2012 Mr. Eric Scott Environmental Protection Specialist Division of Reclamation, Mining and Safety 1313 Sherman Street, Room 215 Denver, Colorado 80203 (303) 289 -8555 Fax: (303) 289 -7707 RE: Submittal of Adequacy Review Comments for Amendment (AM -2) for Turnpike Mining Resource, DRMS Permit No. M- 2004 -009 Dear Mr. Scott: Responses to your preliminary Adequacy Review letter of August 10, 2012 for the referenced amendment are provided below in regular print underneath each of your original review comments which are in bold. Initials of the responder are given in italics at the end of each statement indicating RL for Rob Laird of Asphalt Specialties Co., Inc. ( "ASCI ") and PFW for Peter Wayland of Weiland, Inc. If there are changes to an Exhibit based on the Adequacy Review from the initial submittal of the amendment application, it is noted in the response. Only those text Exhibits which have been changed due to this Adequacy Review are being re- submitted. All map Exhibits are being re- submitted. ASCI has employed Mr. Wayland for some of the more technical issues with the permit. Mr. Wayland has over 20 years of professional experience and 15 years of experience in permitting sand and gravel operations. With a Master's Degree in Hydrogeology from the University of Colorado, Boulder, he has specific expertise relevant to hydrologic balance and water quality in the Colorado Front Range. Additionally, Martin & Martin Engineers have been employed by the Town of Erie and ASCI to complete the floodplain Letter of Map Revision (LOMR) for the property. APPLICATION FORM: The current and primary future post - mining land uses are identified as "developed water resource" on page 4 of the application form. This does not seem to be the correct choice. The only existing reservoir on site is part of the City of Erie's new PWTP, and the remaining previously planned lined reservoirs are now expected to be backfilled with shale. Current and post mining land uses should be changed to Industrial/Commercial to reflect the current state of the site (active mining) as well as the new primary future land use. On a related topic - post mining land use shown on the forms in Exhibit Q will also need to be corrected and re -filed for the notice to County Commissioners and Soil Conservation Service.
