Environmental Protection Specialist Colorado Department of Natural Resources Division of Reclamation, Mining and Safety Office of Mined Land Reclamation 1313 Sherman Street, Room 215 Denver, Colorado 80203 Re: Permit No. M-1980-244; Cripple Creek & Victor Gold Mining Company ("CC&V"); Cresson Project; — Request for Technical Revision ("TR -76") two pipelines Arequa Gulch Adsorption, Desorption, Recovery (AGADR) to Squaw Gulch ADR (SGADR) FECEIVED •- OCT 3C27`3 01\12o':i`rsi us L CLAMATION MINING AND SAFETY Dear Mr. Cazier: In response to your request for additional information on 10/26/15 regarding the above referenced submittal we offer the following clarifications (in italics). 1) Drawing D200: a. The Division was under the impression that the 14 -inch diameter barren solution line would be double contained when crossing the unlined area between the SGVLF and the AGVLF. Section callout A/D200 appears to be off the liner area and the corresponding detail does not show double containment. Similarly, Detail B/D200 implies the pipe-in-pipe/sleeve design is only required "If Vehicle Access Is Required". Please provide clarification and revise Drawing D200 as appropriate. Section A/D200 is shown as being within the Mill Platform Drainline Containment Area on Drawing D200. This area is lined and is depicted as such on the drawing (dashed line labeled as Mill Platform Drainline Containment Area Liner Limits — three labels). There is also a dashed line depicting the Liner Limit for the Squaw VLF which is also labeled. Section B/D200 is located in the area between the two liner extents. The unlined area is also shown/labeled on the profile. The title under Section B/D200 is not intended to suggest that this section of pipe will only be `pipe -in pipe " if vehicle access is required, it was intended to show how the pipe would be protected/covered if vehicle access were required. The pipe section will be `pipe -in pipe " where it is off liner regardless of any access needs.
