Listed below are adequacy review comments for the Mud Creek Pit .l 12(c) Permit Application, File No. M-2008-
010. The recommendation date for this permit application is May 23, 2008. The Division of Reclamation,
Mining, and Safety (Division) is required to make a recommendation by May 23, 2008. Therefore, your response
to the following adequacy review concerns should be submitted to the Division as soon as possible.
As required by Rule 1.6.5 (2), please submit the proof of notice to all owners of record of surface lands and
easement holders that are on the affected land and 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.
Although proof of publication was supplied by McStone Aggregates, the proofs of notice identified as
Attachment 2 in the .adequacy response letter were not included with the response. Please supply these
notices.
Rule 6 4.4 Exhibit D -Mining Plan
2. Section 3.1.6(1), referred to the in the previous adequacy letter, relates to Section 3.1.6(1) of the Rules and
Regulations, not the Mining Planr
With regard to the topsoil that will be reserved at the site, the soil that is salvaged should consist only of the
collide complex. It covers the vast majority of the portions of the site to be affected and is by far the better
soil for revegetation. For non-irrigated areas, 12 inches is an adequate replacement depth. For irrigated
pasture, an 18 inch minimum replacement depth is necessary to minimize loss of irrigation water and
maximize productivity of revegetation. In .the materials submitted, the proposed stockpile for processing area
A is slated to hold 10,000 c.y. It will take 13,000+ c.y. to replace a foot of soil over this area: Additionally,
reclamation is proposed for the!, bar ditches of the roads. Adequate salvaged topsoil will be necessary to
reclaim and stabilize any cut and, fill slopes along the road. ,Prior to sale of any topsoil, a soil balance should
be conducted between the proposed stockpile amounts and the proposed replacement amounts to ensure
adequate topsoil will be salvaged. The submitted application proposes to add soil amendments and also
proposes use of sediment pond cleanings and processing fines for topsoil. A revision to the permit will need
to be submitted, or a revision" to this application, to incorporate specifics of the use of proposed soil
amendments. The best timing for this is after soil analysis is done at the time of reclamation. The use of fines
or sediment is generally only done when adequate topsoil resource is not available for salvage. However,
