Re: Permit Application Adequacy Review, Hukill Gulch Millsite, File No. M-2009-076
Dear Mr. McHale:
The Division of Reclamation, Mining, and Safety (DRMS) has reviewed the above referenced permit
application and determined that the following issues must be addressed for the application to meet the
requirements of the Mineral Rules and Regulations of the Colorado Mined Land Reclamation Board (Rules).
1. Exhibit B, description of vegetation and soil characteristics must be more detailed and inaccuracies must be
corrected. Venture Resources may want to contact the Natural Resources Conservation Service (MRCS) for
information and assistance. The grass species that are growing at the site must be specifically identified. The
percent cover for grass and woody stemmed communities must be estimated. Inaccuracies include:
a. The site is described as arid; this site is at the higher end of the annual rainfall range for a semi-arid climate.
b. Exhibit B states that there is zero to two inches of poor topsoil at the site. The soil in this location has been
surveyed by NRCS; a complete description of the soil is available and must be provided. Intensive surface
disturbance proposed for the affected land warrants additional site specific investigation and description of
the soil within the area of affected land (see item no. 2 below).
c. Exhibit B states that mountain maples and pinon pines are growing at the site. This is unlikely; the species
in question must be correctly identified. It is preferable to use both common and scientific names in
vegetation description to avoid confusion.
2. Exhibit C states that abandoned mine waste rock and/or ore may be imported for processing from other
locations, with the recognition of a need for waste stream characterization prior to importation. Provide a
commitment to gain approval of a permit modification (Rule 1.1(32)) from DRMS prior to importation of
any mill feed from outside the area of affected land.
3. Exhibit C states that there is only zero to two inches of topsoil in the proposed area of affected land and that
the topsoil is impractical to salvage. While there may be little or no accumulation of true A horizon topsoil at
the site, the NRCS soil description indicates useful thickness of AB horizon and Bw horizon soil is likely to be
available. Please report on site specific investigations of the soil profile and the potential for salvage both for
use in reclamation and to prepare the surface for disposal of tailings.
4. A concrete pad for the crusher feed pile is described in Exhibit C. Additional detail is needed to evaluate
the pad both as an environmental protection facility and for cost of demolition. A detail drawing and
specification of concrete thickness and reinforcing are required. Exhibit C states that the pad will contain 10-
