Re: Sandco Pit, Permit M-1987-064, 112c Amendment Application, Preliminary Adequacy Review Letter.
Dear Mr. Anesi,
I have reviewed the above-named application materials submitted by you on behalf of Sandco, Inc. Most of the
exhibit materials appear to adequately address the amendment application requirements, but there aze a few items
that need further clarification. I have listed these items in the paragraphs below under the exhibit headings to which
they pertain. Please arrange your responses in the same order to facilitate our review. Exhibits not mentioned in
this letter are considered to be adequate at this time.
Exhibit A -Legal Description (Rule 6.4.1)
This is a note of clarification about this exhibit: the oversized sheet containing the legal description of the azeas
comprising the 44.00 acres to be added under this amendment also contains the legal description of other tracts
totaling another 17.49 acres. These other acres appeaz to consist of 16.59 acres of processing azea and 0.90 acre of
river crossing, both of which areas aze akeady included in the permitted acreage. No other accounting of presently-
permitted acreage is presented in the legal description or map, though the permit azea includes a significant amount
of additional azea. The in-stream mining portion of the acres still remains in the permit, and this pazagraph seeks to
clarify that (1) none of the in-stream acres have been released from the permit, even though they do not appeaz on
the legal description, and (2) that only the 44.00 acres first identified comprise [he actual area to be added under
this amendment. No response is needed.
Exhibit C -Pre-mining and Minine Plan Mans (Rule 6.4.3)
The mining plan map does not contain any indication of the direction of mining, though it is requued. This should
be added. Since this is a phased operation (as described under Exhibit D) it might be helpful to depict the site at a
point when it is partially mined, showing all final vs temporary slopes, roadways, etc., as pertinent to the operation.
Neither the pre-mining nor mining plan map contains a labeled pem3it azea boundary. The in-stream extraction
portion of the permitted area is not shown. There is no delineation of the rest of the existing permitted azea,
differentiating it from the area to be added under this amendment. These items should be added.
Please be reminded that the revised map should also include a signature and date.
Exhibit D - Minine Plan (Rule 6.4.4)
The site will be mined in two-acre strips by first removing topsoil, then dry-mining down at partial depth, then wet-
mining down to full depth. Excess topsoil will be spread permanently on the off-permit pasture azeas, which is
acceptable. Topsoil that is needed for final reclamation of the pond slopes (above high water elevation) will be
stockpiled azoand the perimeter of the pond. Please commit to ensuring that (1) sufficient topsoil is salvaged to
perform the reclamation at any point during the operation (which may include some dry-mined acres), (2) all
