Re: New Horizon North Mine — Permit No. C- 2010 -089
Technical Revision No. 4 (TR -04) As -Built Information for NHN -001 Ditches
Preliminary Adequacy Review
Dear Mr. Langenfeld:
Original designs for the sedimentation control features at the New Horizon North Mine are found
in Appendix 2.05.3(4) -1 (Arcadis Report on Sediment Control) of the permit. As- constructed
designs for Pond NHN -001 were approved with TR -0 1 on May 3, 2013. During the latter phase
of the TR -01 review, it was determined that as -built details of the pond's two collection ditches
would be appropriately handled as a separate revision to the permit.
An application for Technical Revision No. 4 (TR -04) was received by the Division on May 21,
2013. With TR -04, Western Fuels- Colorado, LLC (WFC) seeks to incorporate as- constructed
details for the NHN -001 West and NHN -001 East ditches into Section 2.05.3(4) of the permit.
The Division deemed the application to be complete, for purposes of filing, on May 23, 2013.
We believe that public notice of the application appeared in the May 30, 2013 edition of the San
Miguel Basin Forum. However, no proof of that publication has yet been received by this office.
Please submit Proof of Publication for the TR -04 public notice at your earliest convenience.
No comments or objections to this revision application have been received.
Your application has been evaluated for adequacy with respect to the regulations and the
approved permit. Items requiring your attention and response are listed below.
Adequacy Items
The Section 2.05.3(4) Table of Contents (TOC) submitted with the application is not the
same version that was approved with TR -01.
a. Maps 2.05.3(4) -6, -7 and -8 are not listed, and should be added to the TOC List of
Maps.
