units that are mined or affected at the Foidel Creek Mine, and therefore, will have similar characteristics, with little
or no potential to adversely affect water quality, flows or vegetation; create public health hazards; or cause
instability in the CRDA Expansion area.
Permanent placement will involve dumping the material in piles or windrows, and then spreading and compacting
the materials in uniform lifts of 12- inches or less, to 90 percent of maximum dry density (AASHTO). If field
testing indicates that compaction requirements can be consistently met with thicker lifts, lift thickness may be
increased up to a maximum of 24- inches. Proper moisture control will be important in assuring adequate
compaction. Compaction will be verified through regular compaction testing and documentation of compaction
results and proper construction in both the Construction Certification (30CFR77.214 -215) and the Quarterly Refuse
Pile Inspection Report. In addition to regular compaction testing and monitoring of water levels, the design
engineer (NWCC) will inspect (and test, as appropriate) key construction activities, including: 1) Foundation
conditions following soil and cover material stripping; 2) Underdrain materials and construction (to be photo -
documented consistent with the applicable requirements of Rule 4.09.1(11)(c)); 3) Coal refuse materials; 4) Initial
and ongoing coal refuse placement (quarterly); and 5) Cover ands soil material placement and revegetation. A
report will be prepared and submitted to the CDRMS within two weeks following each regularly scheduled
quarterly inspection, and a copy will be retained at the mine site. If an inspection identifies potential hazards, TCC
will notify the CDRMS promptly, and develop appropriate emergency protection and remediation plans.
Temporary refuse placement (primarily during the winter months) will involve placement of refuse materials in
temporary stockpile areas to avoid placement when these materials may be frozen. When prevailing weather
conditions warm to the point where any frozen materials are thawed, the material which has been temporarily
stockpiled will be re- handled, placed, and compacted, consistent with permanent placement practices. Initial
CRDA construction will involve placement of up to approximately 3.0 MM cubic yards of refuse material to a
height of approximately 100 feet. Subsequent progressive CRDA construction will result in refuse placement up to
the maximum design height and capacity, with progressive soil and cover material stripping and stockpiling, and
extension of designed drainage structures. As CRDA construction progresses, fill areas and benches will be
completed and graded, and cover and soil materials will be replaced to stabilize and reclaim these areas. Both
cover and soil materials may either be direct handled and placed or recovered and placed from stockpile, dependent
on construction scheduling and equipment availability. A minimum of 4.0 feet of suitable cover (2.5 feet) and soil
(1.5 feet) material will be replaced on all reclaimed areas, followed by re- seeding with the Rangeland Seed Mixture
(Table 55). Reclaimed areas will be managed in the same way as other reclamation, with regular inspections and
maintenance to identify and control any excessive erosion, and spraying, as necessary, consistent with the approved
Weed Management Plan to control noxious weeds.
TCC's bond reclamation cost estimate for the CRDA Expansion takes into account the consideration that bond
monies have already been posted for the existing Refuse Pile, which includes the entire eastern side (approximately
40 acres) that will be redisturbed by the proposed CRDA Expansion. This existing bond (amount corresponding to
acres to be redisturbed is approximately $360K), along with the calculated bond coverage for a 50 acre area
(approximately $380K), addresses bonding for the initial area of disturbance, as shown on Drawing C -102 in
Exhibit 26C. This initial bonded area includes redisturbance of the eastern side of the existing RDA
(approximately 40 acres), the initial CRDA bonded disturbance area (approximately 30.3 acres), haulroad
disturbance (approximately 2.4 acres), stockpile and ditch disturbance (approximately 9.4 acres), stockpile access
corridors (0.4 acres), and a bonded buffer of approximately 7.5 acres to address any minor unplanned disturbances.
With a total facility life of approximately 14 to 20 years, it is anticipated that the remaining 50 acres of the total
CRDA expansion area of 140 acres will be bonded in two future bond increments of approximately 20 -30 acres
each (each increment will be approximately $150K - $230K, depending on size). Bond Increment I was addressed
in 2013, and Bond Increment lI is anticipated to occur in the 2017 -2021 timeframe. Consistent with the constraints
inherent in a cumulative bonding approach, TCC will clearly delineate bonded areas, will limit disturbance to those
areas, and will work with the CDRMS to determine and maintain adequate bond coverage for all activities.
Concerning the Fish Creek Tipple, no excess spoil or underground development waste will be generated in connection
with the operation. Thus, the requirements of this section and Rule 4.09 are not applicable.
