Re: Schwartzwalder Mine, File No. M- 1977 -300, Technical Revision TR -18 Extension
Request; Additional Requirements
Dear Mr. Whicker:
The Division of Reclamation, Mining, & Safety (Division) has reviewed the information
provided 16 September 2011 by Cotter Corporation (Cotter) which stated the rationale for the
additional extension on TR -18 and the status of completion of TR -18. Based on Cotter's
proposal of a phased operation for TR -18 and the Amendment that will eventually be required to
complete the diversion project, the Division requires the following:
1) TR -18 must be revised to include only the design components that Cotter proposes to be
• contained in Phase 1 as described on page 3 of the letter dated 16 September 2011. The
extension of time to complete Revision TR -18 is granted until 31 October 2011, which will give
the Division time to review the submittal in advance of the new decision deadline of 15
November 2011.
2) All other necessary design components described under Phase 2 on page 3 of the letter dated
16 September 2011 are to be contained in an Amendment that must be submitted for the purpose
of expanding the affected /permit area as needed to accommodate preparation and installation of
the remaining components of the diversion, plus monitoring wells and any other surface or
underground activities that might be appropriate to include. The deadline for submittal of the
Amendment shall be 01 March 2012.
You may call me with questions at 303 - 866 -3567 x8108.
Sincerely,
Office of
Mined Land Reclamation
