16 C1981-041 RN7 findings
Mine entries and ventilation shafts were sealed with concrete and at least ten feet of
non-combustible material, or simply backfilled with 25 feet of non -combustible material in
accordance with procedures specified in the approved permit. Drill holes and monitoring wells
have been filled with drill hole cuttings or sealant and plugged with cement.

Disturbed areas other than refuse areas have been backfilled to approximate original contour, with
the exception of a designated portion of the South Portal facilities area, for which the Division
(within Permit Revision No. 3) approved a Steep Slope Variance from Approximate Original
Contour, to allow for retention of facilities to support an alternative “Industrial or Commercial”
postmining land use. The reader is referred to Section B.VIII of the Proposed Decision and
Findings of Compliance for PR-3 dated July 30, 2007, for findings specific to the approval of the
Steep Slope Variance from Approximate Original Contour, and to Section B.X of that document,
for findings specific to proposed approval of the alternative “Industrial or Commercial”
postmining land use at the South Portal facilities area. There are no plans for retention of
highwalls.

With PR-4, the Division approved an alternative “Industrial or Commercial” postmining land use
for the Unit Train Loadout area. See Section B.X of the PR-4 Findings document for specific
findings applicable to approval of the alternative postmining land use.

Refuse areas have been compacted and graded to final design contours and covered with the
required thickness of non-toxic, non-combustible material (24" on CRDA-2, 18" on RSRDA, and
CRDA-1). This cover thickness includes topsoil.

Temporary roads have been reclaimed. All roads will be reclaimed with the exception of roads
approved for the postmining land use (listed in Section B.I. of this document). Roads were ripped,
cuts and fills returned to approximate original contour, and the entire surface regraded.

Topsoil was redistributed approximately 6" thick on all reclaimed refuse disposal areas, the North
Portal facilities area, and the Cameo Borrow Area No. 2. Portions of areas which were disturbed
prior to any reclamation requirements and from which no topsoil was salvaged, including the South
Portal area, and the Unit Train Loadout were surfaced with at least 6 inches of the best available
material on site following removal of coaly material. Disturbed areas were drill seeded or
hydroseeded with the seed mixes listed in Table 14-2 of the permit application.

Current Reclamation Status

Prior to cessation of coal extraction in December 1999, final reclamation activity had been limited
to the lower benches of the CRDA-1 and CRDA-2 refuse disposal areas (1994), and certain
ancillary facility areas including the North Decline (1991-1993), South Lease exploration drill
sites and roads (1985/1986), and Northwest Intake Portal (1993). The South Fan facility area and
associated borrow area and access road, and the 2 West Portal disturbed area was reclaimed in
2000 and 2001. Final reclamation including structural demolition and removal, backfilling and
grading, topsoiling, and revegetation began on a large scale in 2001/2002. Final reclamation has
been completed at a number of additional major facility areas including CRDA-1 and CRDA-2
refuse areas, RSRDA refuse area slopes, the North Portal facility area, Cameo Soil Borrow Areas
