RE: S & H Mine; DRMS File No. M-2000-158; Amendment 02, Adequacy Review #4
Dear Mr. Hagen,
The Division of Reclamation, Mining and Safety (Division) has completed its review of your
adequacy review response letter and conducted a financial warranty estimate based on the
information supplied. The items discussed below will need to addressed prior to the Division's
approval of the amendment application. The decision date for the amendment application is
February 28, 2011 per your extension request. Please be advised that if you are unable to
satisfactorily address any concerns identified in these reviews before the decision date, it will be
your responsibility to request an extension of the review period. If there are outstanding
issues that have not been adequately addressed prior to the end of the review period, and no
extension has been requested, the Division will deny this application. Pursuant to Rule 1.4.1 (9),
the review period cannot be extended beyond 365 days from the date the application was filed.
This deadline is March 1, 2011.
6.4.5 Exhibit E -- Reclamation Plan
1.) Please identify the purpose of the buried riprap dikes depicted in the Permanent Erosion
Control Plan?
2.) The Division approves of the proposed weed control plan for the site. During the site
visit on February 3, 2011 is appears a significant effort to treat noxious weeds occurred.
The Applicant may want to consider conducting a temporary grass seeding in these
treated areas to promote non-noxious weed establishment. If the site will be inactive for
four or five years, without competitive vegetation the noxious weeds will return with
added vigor enhancing the cost and time to treat the infestations.
6.4.7 Exhibit G - Water Information
3.) Please indicate how frequently and for what duration baseline groundwater data will be
collected. At a minimum, the Division will require monthly monitoring for 12 months.
Please commit to submitting baseline groundwater monitoring data to the Division prior
to installing the slurry walls. Also, please commit to identifying what groundwater
elevation(s) will be the benchmark for the two foot trigger point outlined in the response
letter.
4.) Please commit to notifying the Division within 24 hours of when a trigger point for
mitigation has been observed.
