The Division received your adequacy responses for the Fetcher/Vale Gravel Pit Application, Permit
No. M-2002-119. The Division has some additional concerns that need to be addressed prior to
approval of the application.
1. As required by Rule 1.6.2 (1)(g), please submit the proof of publication of the public notice
circulated in the local newspaper, all owners of record of surface lands, easement holdei-s, and
owners of record of surface lands that are within 200 feet of the boundary of the affected land.
Proof of notice may be return receipts of a Certified Mailing or by proof of personal service.
Rule 6.4.4 Exhibit D-Mining Plan
2. The Division has additional questions regarding the 100 year 24 hour sediment trap proposed at
the mine site.
Upon further review of the sediment trap, it appears that an application for ati erosion control
dam must be approved by the Division of Water Resource, Office of State Engineer, In
addition, if the erosion control reservoir is constructed with a capacity in excess of two acre-
feet, an ungated twelve inch diameter outlet pip must be installed to allow for draining within
a thirty-six hour period any amount of water in excess of two acre feet. A copy of the
requirements from the Division of Water Resources web page and application form is
included for reference.
• Please inform the Division if filter fabric will be used, and describe how the embankment
will be compacted to meet the required safety factor for the detention structure.
• Deposited sediment should be inspected and/or removed from behind the detention structure
after major storms or when 1/3 of the pond volume has been filled with sediment. Please
commit to this maintenance practice.
3. The applicant states that a 12' buffer will be maintained from the edge of the stockpile to the top
of the mining cut. If the pit is mined to a depth of 60 feet at a O.Sh:l v slope, the topsoil pile may
become unstable and slope failure may occur. The Division does not believe a 12' buffer
distance is adequate due to the depth and slope of the pit. The operator has the following options:
