The Division has modified the original extent of NOV C-95-007 to include haul road
sediment deposition in 006 Gulch near the outlet of culvert ME-5. Please find enclosed
the modification notice. A description of the modification follows.
Rule 4.03.1(1)(6) states that to the extent possible using the best technology currently
available, haul road drainage shall not contribute additional suspended solids to
streamflow or to runoff outside the permit area. Field conditions observed during the
March 28, 1995 inspection and described on page III H of that report, indicate that a
violation of 4.03.1(1)(6) had occurred in 006 Gulch, near the outlet of ME-5. Since
NOV C-95-007 already cited other violations of 4.03.1(1)(6), we have modified the
existing NOV to include this violation rather than issue additional enforcement action.
The modification requires Seneca Coal Company to submit a COMPLETE application
for technical revision by April 30, 1995, to address appropriate erosion and siltation
control measures for the sections of "Mine Entrance" and "A" haul roads that cause
additional contributions of suspended solids to streamfiow or to runoff outside the permit
area near the outlet of culvert ME-5.
Please note that in addition to submittal of a TR, the Division requires excavation of the
haul road sediment deposited in 006 Gulch near the outlet of culvert ME-5 and that the
excavated material be removed and disposed of appropriately. Haul road sediment
previously excavated from ME-5 area and placed on the bank of 006 Gulch shall also be
removed. Excavation and removal of haul road sediment from 006 Gulch is to occur by
April 20, 1995.
