<br />Re: Peabody Sage Creek Mine (Permit No. C-2009-087)
<br /> Technical Revision Application No. 9 (TR-9)
<br /> Hydrology Monitoring Plan Changes
<br />
<br />
<br />Dear Mr. Boehms:
<br />
<br />The Division of Reclamation, Mining and Safety hereby issues notice, in accordance with Title 34,
<br />Article 33, Section 118, Paragraph 3, of the Colorado Revised Statutes, that on August 15, 2016,
<br />an application to revise coal mining operations at the Peabody Sage Creek Mine was considered
<br />complete for the purposes of filing. All review and comment periods as provided in the Act and
<br />the Regulations initiate from this date of filing.
<br />
<br />Peabody Sage Creek Mining, LLC. has submitted this Technical Revision (TR-09) for Division
<br />approval to modify the hydrologic monitoring plan. The proposed revised plan will eliminate
<br />monitoring of several spoil spring sites, suspend monitoring of several wells while the mine is idle,
<br />modify the frequency for bedrock and alluvial well monitoring, discontinue monitoring at Pond
<br />004 since two additional upstream monitoring points have been initiated and the addition of a
<br />qualifier that certain monitoring parameters will only be measured if the flow is less than 1 gallon
<br />per minute at all stream and spring monitoring sites. The applicant is not proposing additional
<br />surface disturbance outside of the area currently approved for disturbance.
<br />
<br />The underground coal mining operation is on land located approximately 9 miles Southeast of
<br />Hayden. The permit area is further described as follows:
<br />
<br />Township 5 North, Range 87 West, all or portions of Sections 1, 2, 3, 4, 5, 8, 9, 10, 11, 12, 13, 14,
<br />15, 16, 21 and 22; Township 6 North, Range 87 West, all or portions of Sections 27, 28, 29, 32, 33,
