BOX 33695 DENVER, COLORADO 80233-0695 303-452-6111 <br />March 21, 2016 <br />Mr. Brock Bowles <br />Environmental Protection Specialist RECEIVED <br />Colorado Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 MAR 2 2; 2616 <br />Denver, CO 80203 <br />RE: New Horizon Mine DIVISION OF RECLAMATION <br />MININGAND SAFETY <br />Permit No. C-1981-008 <br />TR -70 Adequacy Review Response <br />Dear Mr. Bowles: <br />Tri-State Generation and Transmission Association (Tri-State) has received your adequacy <br />review letter for TR -70, dated March 1, 2016 and provides the following responses to your comments on <br />behalf of the Western Fuels -Colorado, A Limited Liability Company (Western Fuels -Colorado) New <br />Horizon Mine. <br />Section 2.04.9 — Soil Resource Information <br />On page -24 in bullet 17, it states that Map 2.05.4-4, -6 and -9 show the topsoil placement. Map <br />2.05.4- 9 is the topsoil stockpile map and doesn't show topsoil placement. Map 2.05.4-7 shows <br />topsoil placement for the northwest properties. This appears to be a typo. Please clam. <br />Response: TR -70 proposes to remove Map 2.05.4-7 from the PAP and consolidate the <br />information under Map 2.05.4-9. Therefore, the topsoil placement information for Zone 7 and <br />Zone 8 in the northwest portion of the permit has been included on Map 2.05.4-9. <br />Section 2.05.3(3) — Mine Facilities <br />1. On page 2.05.3(3)-3, it appears that bullet e. was omitted from the revised page. Please correct <br />this typo for consistency with page -4. <br />Response: Bullet `e' has been included on page 2.05.3(3)-3 for consistency with page -4. <br />2. Map 2.05.3(3)-1 Surface Water Hydrology does not show the straw wattles and the small area <br />exemption on the Morgan property. Please include these features on the map as they are current <br />features of surface water hydrology. <br />Response: The straw wattles and the small area exemption on the Morgan property have been <br />included on Map 2.05.3(3)-1. <br />3. Approved Map 2.05.3(3)-1 delineates Ditches C-10 draining a basin of 5.2 acres to Pond 013 <br />and DI W draining a basin of 25.1 acres to what appears to be Pond 015. Both C-10 and DI W <br />are not identified on the proposed revised Map 2.05.3(3)-1 submitted with the TR -70 application. <br />Based on the contour of the land it may be the case that ditches C-10 and Dl W may not be <br />required; however, a discussion as to the prevention of disturbed area run-off from the west side <br />of the permit to Pond 013 was not included.
