Re: Westside Gravel, File M-2003-003, New 112 Application Approval, Bond Calculation.
Deaz Mr. Shaw,
I have approved the above-named permit application. Additionally, I have a few comments to include in this letter
to ensure we both understand the permit conditions equally. I have listed these items below:
The permit area is still 100 acres. The 82.83-acre figure is the coaect affected area acreage, as it is delineated on
all the revised maps. It is required that once the site is permitted, the affected azea boundary is well marked in a
visible and durable manner. You will also need to post a correct permit ID sign. Please refer to Rule 3.1.12 for
description of the complete sign contents.
Because this is a phased operation, and the bond amount is determined partly by the size of the phases, it will be
important that the boundary of the active phase be well marked, so all disturbance remains inside'that phase.
The revised maps all showed a bold line along the outer margin of the unaffected area, which delineates a 100-acre
area. Though not labeled, I interpret this to line to depict the permit area boundary. I will add this label to the set
of maps, unless you instruct me not to do so.
It is not cleaz by looking at the revised maps whether the affected area acreage figure, 82.83 acres, includes the
three small areas which will be affected: the scale and scalehouse azea, the segment of the entrance road neazest the
gate, and the gulch crossing. No further comment is needed from you, as these areas aze minimal and their
reclamation will be included in the bond, as appropriate.
The sediment control detail for the gulch crossing was appreciated, but I would recommend addirig silt fence or
straw bales on the downstream side of the culvert and fill material also.
The possible onsite hatching (asphalt or concrete) will be included at this time as one of the approved activities in
your mining plan, with no further details required at this time. Please ensure that you have all proper permits for
these actvities, such as the ADEN from Department of Health, and that all hydrocarbons be stored with appropriate
impermeable containment. If possible, I would ask that you contact this office prior to commencing any hatching
so that we may discuss the plant and its operation.
The bond calculation for the phased mining of the site was performed using the following assumptions: that the
reclamation of any "active" area being disturbed required slope reduction to 3:1, replacement of overburden and
topsoil, ripping all compacted areas, removal of structures and debris, and full revegetation. Outstanding
