Re: Deepe Farm Pit
Our File No. 81-302
Dear Mr. Hart:
I have reviewed the above application for adequacy and have the following
questions, comments, and suggestions which are intended to aid you in
bringing this application into full compliance with the law and to the
satisfaction of the Mined Land Reclamation Board. Please address each of
the following items in detail.
1. Are the five steps of general mining procedures (as described in
Exhibit B) to be the actual procedures used at the Deepe Farm Pit?
2. Please delineate the proposed locations of the deposit and topsoil
stockpiles on Exhibit C.
If topsoil stockpiles will remain undisturbed for more than one growing
season, a suitable cover of vegetation should be established on the stock-
piles to avoid deterioration of the topsoil prior to utilization during
reclamation.
In consideration of our recent inspection of the Turnpike pit, it
is advisable to strategically locate deposit stockpiles along the western
portion of a given stage of mining to reduce noise and visual effects of the
excavation. Additionally, consideration should be given to the proposed
height and shape of the stockpiles in order to minimize particle blowing
and "unsightliness", and to improve stability of the stockpiles for general
public safety.
3. The Division recommends that topsoil and vegetation removal occur in
defined increments immediately in advance of mining in a given phase. This
would tend to minimize wind and water erosion as mining progresses over the
site. Additionally, reclamation should follow in defined increments as soon
as possible following mining in a given phase. The application, as submitted,
