The Division completed a technical review of the referenced application. Following aze items of
concern which need to be addressed in order for the application to meet the minimum
requirements of the AcUMineral Rules and Regulations:
1. Exhibit C -are there any power and/or communication lines within 200 feet of the affected
land, especially in the northern part of the affected land boundary? 1f so, they must be
shown on one, or both, of the Exhibit maps (6.4.3(a)). Also, the owner's name, type of
structure and location of the structure(s) must be shown on the Exhibit maps (6.4.3(8)).
2. Rule 3.1.5 - Backfilling -will the backfilled material need to be compacted to ensure
that it will remain stable (3.1.5(2))?
3. Rule 3.1.5 -the applicant proposes to grade the reservoir slopes to 3:1 or less to provide
"the best protection for wave cut action on the reservoir shore." Actually, armoring the
shore slopes will provide the best protection from wave cut action. Normally, the west and
north facing slopes are armored. It is not necessazy to azmor the entire slope, only the
interval from a couple of feet above the anticipated high water line to a few feet below the
anticipated low water line need to be armored in order to achieve the best protection for
wave cut action. The applicant should include a plan to install the best wave erosion
protective system for the reservoir slopes to ensure they will remain stable during high
wind conditions.
4. Rule 3.1.6 -part of the proposed affected land will contain a water storage facility. How
will the facility be filled? How does the applicant propose to release water from the
facility?
5. Rule 3.1.6 -the applicant shall minimize disturbances to the prevailing hydrologic balance
of the affected land and of the surrounding area. Specifically, the applicant shall minimize
disturbances to all nearby water wells. Prior to disturbing any acreage in Phase 1 of the
proposed amended area, the applicant shall receive approval from the DMG of a plan that
