RE: MID-CONTINENT MID-TERM BOND RESPONSE
I have completed my review of the above referenced submittal . In this
response, the operator identified six (6) issues which they felt needed
clarification. My findings, which are included below, are formatted to
address each of these issues. These findings also reflect our meeting with
the operator of July 9, 1986.
I. Verification of Disturbed Acreage.
The operator has presented evidence that the original calculations of
disturbed areas included in the permit are in error, and that the total
surface disturbance is 283.3 acres rather than 432 acres. However, no
discussion concerning how the limits of the disturbance were calculated was
included in the submittal . Specifically, the division requires information as
to whether outslope disturbance created by downspoiling on mine benches and
roads was included in the measurements. These areas must be included at least
with respect to revegetation costs. The Division is prepared to accept a new
estimate for the disturbed acreage upon clarification of the estimating
method. The operator has expressed his intent to supply the required
information.
II. Backfilling and Grading, and the Application of Approximate Original
Contour (AOC) Requirements.
Two issues concerning AOC are addressed in the Mid-Continent submittal . The
operator contends that; (1 ) a variance from AOC requirements has been granted
by the Division, and therefore, (2) AOC requirements should not be considered
in the bond calculations.
First, it must be noted that although a variance for steep slope mining was
granted, it was approved with stipulations. These stipulations require the
submittal of stability analyses and detailed reclamation plans for the
applicable surface disturbances (mainly haul roads and mine benches). To date
the Division has not received this information, as the operator is in the
process of a continuing study which will not be completed until December,
1987. Until a specific reclamation plan is proposed by the operator and
approved by the Division, bonding cannot be based on the current proposal from
the operator, which does not include backfilling and grading.
