The Division of Reclamation, Mining and Safety hereby issues notice, in accordance with Title 34, Article 33, Section 118,
Paragraph 3, of the Colorado Revised Statutes, that on June 28, 2010, an application to revise coal mining operations at the
Seneca II Mine was considered complete for the purposes of filing. All review and comment periods as provided in the Act and
the Regulations initiate from this date of filing.
This revision application proposes a reduction in size of the Seneca II permit boundary. The proposed reduction is to
accommodate the new Peabody Sage Creek Mine (PSCM) permit area, which will incorporate approximately 3, 011.9 acres of
the original Seneca II permit area. The revised Seneca II permit area will retain 386.5 acres of the original permit area that
includes 271.0 disturbed acres. The revised Seneca II mine permit boundary encompasses one isolated watershed and separates
runoff from the Seneca II mine and the new PSCM permit area. The watershed discharges to pond 008, which is an approved
NPDES discharge point. Proposed changes to the current permit boundary and associated changes to the operations and
reclamation plans are set forth in a new volume to the permit application package titled "Permit Revision (PR-02) reduced
permit area.
The surface coal mining operation is on land located approximately 9 miles Southeast of Hayden, Colorado. The permit area is
further described as follows:
T5N, R87W; All of Sections 1, 2 and 12; Portions of Sections 3, 11 and 13
T6N, R87W; Portions of Sections 27, 34, 35 and 36
T5N, R86W; Portions of Sections 6 and 7.
The above-mentioned tracts of land are shown on USGS 7.5 minute Quadrangle map of Milner & Mount Harris.
Mining operations have been completed within the proposed reduced permit area, the entire area has been backfrlled, topsoiled,
and seeded, and Phase I bond release has been approved. Continuing activity during the liability period will be limited to
monitoring and maintenance. Certain modifications to the approved revegetation success demonstration and success standards
have been proposed in the application, in association with the reduced permit acreage proposed.
The revision application and the currently approved permit application can both be viewed on laser fiche on the DRMS website
(http://www.mining.state.co.us/ImaizedDocuments.htm). The revised maps and narrative can be found in the revision index
class, while the currently approved narrative and map are in the permit file index class. To access the revision materials, click

The applicant is required to publish notice in a local newspaper that this application has been deemed complete. At the time of
publication of this notice, the applicant is additionally required to place a copy of this application at the Hayden Public Library,
