DRMS conducted the bond release/termination of jurisdiction inspection on May 18, 2010.The
inspection was originally scheduled for December 9, 2010, but was postponed due to winter
weather conditions.
DRMS prepared a bond release application package for the Coal Gulch revoked site and found
the package to be complete on November 16, 2009.The permit area is on private and state
lands and encompassed 725 acres, of which approximately 16.5 acres of land surface were
disturbed.
The Divisions Inactive Mined Lands Program reclaimed the disturbed area in 1994. Work was
conducted by private contractors, and included: backfilling as much highwall as possible;
constructing"French" drains for natural drainage to flow through; backfilling exposed coal
seams; topsoiling and revegetating the disturbed areas; and regrading and revegetating portal
face-up. All the funds from the forfeiture of bond associated with Minerals Program permit, 77-
3 ug/c, have been utilized.
The reclaimed areas appear erosionally stable and weeds are locally abundant.The clean water
diversion on the south side of the gulch is intact and effective. The surface depression/pond to
the northwest the site is less than one-half acre in size and only a few feet deep and is not a
designated impoundment structure.
A constructed sediment control/mine water treatment pond still exists on the site. At the time
of inspection there was no water in the pond.The primary discharge pipe appears to be clogged
by erosional or animal processes.The emergency spillway is an open channel.The pond was
originally constructed and certified to hold a 25-year, 24-hour storm. Any water discharging
from this pond would make its way to the culverts below the adjacent highway.
Historically, a one-acre portion of the permit area was being used for equipment/junk storage.
At the time of inspection the majority of the objects that were being stored on-site had been
removed. Some spare parts and tires still remain, but do not pose an adverse affect to the site.
