Heit Sand and Gravel 112c Permit Application- Third Adequacy Review
Deat Mr. Gesso,
Listed below are the third adequacy review comments for the Heit Sand and Gravel 112(c) Pemlit Application, File No. M-
2003-016. The Division of Minerals and Geology ("Division") is required to make a recommendation no later than August 4,
2003, therefore, your response to the following adequacy review concerns should be submitted to the Division as soon as
possible.
Rule 6.4.4 Exhibit D- Mining Plan
1. The second adequacy review requested that the Applicant submit measures that will be taken in order to contain spills
related to damaged fittings on the tanks or which occur while filling these tanks and barrels. The Applicant committed to
construction of berms azormd the drums to serve as secondary containment. This commitment, however, does not
address secondary containment related to the above-ground storage tanks, nor will the proposed berms prevent spilled
materials from infiltrating into the soil. Please indicate what other measures will be incorporated, such as berms and
liners, for both the drums and the above-ground storage tanks.
2. For purposes of clarification, the Mine Plan implies that the slurry wall will be installed prior to dewatering the pit.
Please specify the timing on these events.
3. The fnst adequacy review response indicates that a French drain will be installed at the site. Please specify the timing of
installation relative to installafion of the slurry wall. Also be aware that design and specificafions for the French drain
must be submitted to the Division in the form of a Technical Revision for review and approval prior to its installation.
Rule 6.4.7 Exhibit G -Water Information
4. The second adequacy review requested that the Applicant provide a study based on current, site specific-data, or support
the findings in the WWE document, submitted with the first adequacy review response, with current, site-specific data.
The Applicant has submitted a follow up study -Groundwater Monitoring and Mitigation Plan for Heit Aggregate
Resource Operation Weld County Aquatic and Wetland Nursery and Coyle Property (W WE second report) -which does
address certain site-specific issues, but wMch does not define a model for the groundwater and potential impacts in the
vicinity of the site. Therefore, the Division will still require further reporting in the form of a Technical Revision or
Amendment and Division approval, related to a groundwater and impact model prior to the commencement of mining
activity at the site. This model may dictate required changes to the mining plan for the site.
5. The second adequacy review indicated that due to the uncertainty of the accuracy of the fmdings in the first W WE report,
under current conditions, the Division cannot accept the proposed trigger point, which would require assessment and
possible mitigation, of a drop of 5 feet in groundwater level below seasonal fluctuation as proposed by the Applicant, and
