RE: MLRD Permit #M-73-021
Request for Administrative Decision Regarding Limit of
Excavation, Morrison Quarry
Dear Mr. Mount:
~;I~
On October 16, 1992, at our request, we were visited by Bill
York-Fiern, an inspector from your division, with regard to a
hazardous slope failure situation, which has developed on the
west facing highwalls of our Quarry. Subsequently, on Monday,
Octaber 19, 1992, we were inspected by an MSHA team due to the
above concern. Pursuant to that inspection, MSHA mandated that
we reduce the highwall slopes within a short time frame, in order
to mitigate a potentially life threatening situation.
Due to the nature of this emergency we are requesting that we be
allowed, through your administrative decision, to increase the
outer limits of our excavated slopes to the east, by as much as
200'. This is well within our permit boundary. The approval of
this increased limit of excavation will not alter the visual
impact of the Quarry to the residents east of us. The urgency of
this situation requires an answer from MLRD by October 28, 1992.
We are concurrently seeking approval from Jefferson County, and
because of the emergency nature of our request, expect immediate
approval. We fully understand the need for an amendment to our
mine plan in order to fulfill the regulatory requirement of an
increase in the mining boundary within the permit area. We will
be more than happy to comply with an amendment subsequent to an
administrative decision to approve the new limit of excavation
for this emergency situation. The amendment would include
highwall, bench, and backfill specifications both in plan and
profile, and other documentation if required.
Prior to Wednesday, October 28, we would welcome a site tour by
the Division staff, so that the new limit of excavation can be
physically observed within the Quarry.
