MID-CONTINENT RESOURCES ASSESSMENT CONFERENCE JULY 17, 1990
* Today we are holding assessment conferences for notices of violation
C-90-014 and C-90-015 issued to Mid-Continent Resources, Inc. for the Coal
Basin Mines ( File C-81 -017) .
* These violations were issued as a result of a partial inspection of the mine
site by Michael Savage and Harry Ranney of the Division on May 17, 1990. The
violations were issued on-site at the close of the inspection on May 17, 1990
and were received by Mr. Lew Thompson, Environmental Coordinator for Mid-
Continent.
* Proposed civil penalties for both violations were issued by the Division on
June 7, 1990 and received by Mid- Continent on June 11 , 1990. Requests for
assessment conferences are received by the Division on June 15, 1990.
* Due to the desire to conduct as much business as possible in one day and
personnel scheduling conflicts, MCR waived their 30 day time period for
holding the assessment conference and the conference was scheduled for today.
NOV C-90-014
* This notice was issued for, " failure to maintain haul road (specifically
culvert D-2) to prevent erosion and siltation. 2. Failure to construct culvert

PERMIT N/A
* The area of concern was road drainage culvert D-2 as depicted on "No. 1 Mine
Haulage Road D Drainage Plan". The concerns with this culvert were two fold.
First, the inlet to the culvert was 1/2 full of sediment, and the sediment
appeared to be inhibiting proper function of the culvert. Second, the outlet
end of the culvert had eroded, resulting in piping beneath the road surface,
with attendant collapse of a portion of the road surface ( approx. 50' long
and 8' wide) and downslope erosion beside the CMP drop structure down the road
outslope. See photos.
* The abatement for this notice was to,"l . Repair or replace the CMP culvert
D-2 so as to prevent further piping and outslope erosion. 2. Repair and
stabilize road outslope at outlet of D-2. " The abatements were to be
completed by June 16, 1990.
