Subject: Permit No. M-1978-116, SM-18 Mine
Technical Revision Request
Dear Mr. Mount:
Cotter Corporation is hereby applying for a Technical Revision to mine reclamation Permit No.
M-1978-116 (as mentioned in our phone conversation of July 12, 2004). This permit covers the
SM-18 Mine, used to produce ore from the U.S. Department of Department of Energy Lease
Block No. AT(OS-1)-ML-60.8-C-SM-18. In order to more effectively mine the reserves on the
south portion of the lease block, Cotter's application for a technical revision involves deleting
• undisturbed acreage permitted at the SM-18 portal azea and adding acreage elsewhere.
The area Cotter is requesting to be released totals 5.0 acres. When the original application for
Permit M-1978-116 was submitted, Cotter could anticipate the need for surface disturbance but
could not show the exact location of some of it on a map. This was particularly true of
ventilation hole sites. The location of vent holes could only be determined as development and
exploration progressed. Cotter's stated intent in the original application was to handle the exact
locations of the permitted acreage for vent holes by means of technical revisions. Only one of
the six permitted vent hole sites was actually constructed.
Some of the other acreage listed on the original Exhibit A for roads and surface facilities is also
not delineated on the original exhibit C mine plan map. Therefore, Cotter cannot show on the
the revised Exhibit C, the boundary of all of the 5.0 undisturbed areas that are being requested
for release. However, the revised Exhibit C does show the undisturbed azeas that were
delineated on the original Exhibit C (in SE'/o SE'/4 Section 21, SW'/a SW'/< Section 22, and NW %4
SW'/< Section 27, T 48N, R.17W). Furthermore, the revised Exhibit C also shows the surveyed
boundary of the total area actually disturbed by mining at the portal site in S W %4 Section 22 and
the one constructed vent hole in NW'/< Section 27. The total acreage permitted originally in
Permit No. M-1978-116 is 14.9 acres. The surveyed boundazies of the actual disturbance
encompass a total of 8.71 acres, leaving a total of 6.19 acres undisturbed. Cotter is requesting
that 5.0 acres of the 6.19 undisturbed acres be released.
