However, DRMS has reviewed your letter, will <br /> include it in the public file, and forward it to the applicant so they are aware of your concerns as <br /> adjacent landowners. <br /> Although you will not be a party to the application process, I wanted to let you know that the <br /> permittee is responsible for maintaining compliance with their approved storm water permit as it was <br /> issued by CDPHE, and minimizing or eliminating any associated off-site erosion. <br /> DRMS is also aware of the concern surrounding the potential exposure of groundwater at the site, and <br /> will be addressing this issue during the amendment review process. The Construction Materials rule <br /> requires operators to minimize any impacts to quantity and quality of the prevailing hydrologic <br /> balance. If the operator plans to expose groundwater, they will first need to obtain the appropriate <br /> permits from the State Engineer's Office - Division of Water Resources, and also demonstrate how long <br /> term groundwater exposure will be addressed in the reclamation plan. <br /> Sincerely, <br /> Eric Scott <br /> Environmental Protection Specialist <br /> Ec: Michael Cunningham; DRMS <br /> 1313 Sheirirnain Street, Room 215, Denver, CO 80203 P 303.866.3567 IF 303.832.8106 Ih-L-LIp w//ire-i in-i in .s,L ,'L . m us 0% Ck <br /> it d IPo Us, Governor Dain Gibbs,11 s, Executive I[A it c it Virginia Brannon, ID-it toit <br /> 4 q <br />
