RE: Policy On Application Reviews Involving Lined Sand and Gravel Pits
The Division has received comments from applicants and their consultants concerning Division
request for design information related to lined sand and gravel pits. These comments questioned
the need for such information, as well as the Division's technical ability to review it.
It is clear that the Division has a need for such design information in order to calculate an
appropriate reclamation bond. It is also clear that the Division has the technical expertise
necessary to review the engineering evaluations and designs. However, it is correct that the
actual authority to review and approve such designs rests with the Office of the State Engineer
(SEO). This review and approval authority is cleazly stated in their "Proposed Guidelines for
Lining Criteria For Gravel Pits"(8/16199), and verified through conversations with personnel in
the Office of the State Engineer.
Therefore, the Minerals Program will no longer approve engineering designs for installing liners
that aze intended to meet SEO water rights protection criteria. An applicant, however, shall be
required to provide DMG any of the following in order to demonstrate compliance with Section
3.1.6 of the Construction Material Rules:
• A copy of the SEO's letter approving the proposed liner design. and a copy of the design and
specifications for inclusion into the applicant's application prior to the Division's approval of
recommendation date, or
• A commitment to stay at least two feet above the historic highest ground water level together
with an adequate means to monitor compliance, or
• A bond adequate to baclcfill the pit to two feet above the historic highest ground water
elevation, or
• A letter from the SEO stating that the applicant has satisfied the SEO requirements for an
augmentation plan or substitute supply plan for ground water exposed to evaporative loss and
has an associated well permit.
