To the extent possible, the individual grids should be marked in the field with durable markers. In instances where this is not possible due to ongo'ng mining or reclamation activities, it should be possible to measure any parcel from an adjoining or nearby grid point. Agreed. This was provided for in the submittal on Page 4 o Exhibit G "Beriveen annual reports, interim activity can be updated by steel [s r vey quality Chain measurements using surrounding QUADS to locate or relo ate missing QUA Ds moved by extraction, and to identify, measure and rep rt activities within a phase." EXHIBIT E -RECLAMATION PLAN RESTORATION GOALS Even though it is probably impossible to predict the exact post-minin contours, a typical post-mining contour cross-section and plan view should be inc uded in the permit application for illustrative purposes. Typicals will be provided at the time of the survey based revised ma s, since the submittal is via Technical Revision and final approvals can occur t that time. Typicals can he modified over time or by later Technical Revision, based upon field experience or other operator/DMG interaction. STABILIZATION Establishing an effective cover equal to or in excess of ]0-25% is mentioned. What constitutes effective cover? is that live vegetative growth or liv vegetative growth plus litter? Please explain. The concept of a cover standard s addressed in further detail later in this letter. Effective cover is intended to imply stabilizing cover, and should i elude dead litter. Percents are generalized based upon gross occular estimates w ich will be revised by subsequent site specific vegetative studies during the fife of the operation. ESTABLISHMENT OFGRASSES A commitment should be incorporated that any mulch used on the ~ite will be certified noxious weed free.
