RE: Permit No. M-78-107 Tozer Pit-Montezuma County
Request for Technical Revision
Dear Mr. Erickson:
Montezuma County (applicant/ operator) is hereby requesting a technical revision to its
current permit referenced above. Discussions with the BLM have resulted in agreement
to modify the original and amended mining plans. The. modification entails extension of
mine phases to the east of the current phases within the 40.51 permitted acreage. BLM
has recommended that the total area of disturbance not exceed 10.99 acres as described
more fully in the attached BLM permit documents. This implies that reclamation must be
completed in proportion and "prior to disturbance in the extension areas (phases. 8 and 9).
To-date, approximately, 7.7 of the 10.99 acres have been, disturbed leaving 3.3 acres
available for future mining. Reclamation work was begun'1in the, northwest section of
Phase 5 a few years back. It is the intent of the operator to complete the required seeding
o€this section in the spring or fall of 2010.
Mining Plan Revision The- overall plan submitted in the 1998 Amendment will ,apply to
the extension area. The attached Exhibit C (R) shows the mine extension area as Phases. 8
and 9. Preservation of 'available vegetation, topsoil and overburden removed in the
extension area will be done in accordance with the current plan. Stormwater drainage
from the extension area will be controlled with the existing detention pond in Phase 3 in
the lower pit and with additional straw bale or excelsior wattles,placement within the
center drainage feature as necessary. No offsite discharge of stormwater will result from
'activities within the mine extension area.
Reclamation Plan Revision As with the mining plan, no alterations to the scope of
reclamation are anticipated. The same standards, in terms of 3:1 (H: V) reclaimed slopes,
grading and seeding.: criteria are applicable to the extended mining`area. Exhibit E (R)
(attached) illustrates the general final topography of the extended mining area.
Ute Mountain Ute Tribe The applicant/ operator does not intend to close the existing
access trail through Phases 5 and 7. Where necessary, the route has been redirected to
allow for mining and processing, but access to the reservation boundary will remain
throughout the life of the mine. The Ute -Mountain Ute Tribe was notified of this issue
and the pending renewal, of the BLM permit and the proposed`DRMS technical revision
request. As of this writing, no response from the tribe has been received:
