or no potential to adversely affect water quality, flows or vegetation; create public health hazards; or cause <br />instability in the CRDA Expansion area. <br />Permanent placement will involve dumping the material in piles or windrows, and then spreading and compacting <br />the materials in uniform lifts of 12- inches or less, to 90 percent of maximum dry density (AASHTO). If field <br />testing indicates that compaction requirements can be consistently met with thicker lifts, lift thickness may be <br />increased up to a maximum of 24- inches. Proper moisture control will be important in assuring adequate <br />compaction. Compaction will be verified through regular compaction testing and documentation of compaction <br />results and proper construction in both the Construction Certification (30CFR77.214 -215) and the Quarterly Refuse <br />Pile Inspection Report. In addition to regular compaction testing and monitoring of water levels, the design <br />engineer (NWCC) will inspect (and test, as appropriate) key construction activities, including: 1) Foundation <br />conditions following soil and cover material stripping; 2) Underdrain materials and construction (to be photo - <br />documented consistent with the applicable requirements of Rule 4.09.1(11)(c)); 3) Coal refuse materials; 4) Initial <br />and ongoing coal refuse placement (quarterly); and 5) Cover and soil material placement and revegetation. A <br />report will be prepared and submitted to the CDRMS within two weeks following each regularly scheduled <br />quarterly inspection, and a copy will be retained at the mine site. If an inspection identifies potential hazards, TC <br />will notify the CDRMS promptly, and develop appropriate emergency protection and remediation plans. <br />Temporary refuse placement (primarily during the winter months) will involve placement of refuse materials in <br />temporary stockpile areas to avoid placement when these materials may be frozen. When prevailing weather <br />conditions warm to the point where any frozen materials are thawed, the material which has been temporarily <br />stockpiled will be re- handled, placed, and compacted, consistent with permanent placement practices. Initial <br />CRDA construction will involve placement of up to approximately 3.0 MM cubic yards of refuse material to a <br />height of approximately 100 feet. Subsequent progressive CRDA construction will result in refuse placement up to <br />the maximum design height and capacity, with progressive soil and cover material stripping and stockpiling, and <br />extension of designed drainage structures. As CRDA construction progresses, fill areas and benches will be <br />completed and graded, and cover and soil materials will be replaced to stabilize and reclaim these areas. Both <br />cover and soil materials may either be direct handled and placed or recovered and placed from stockpile, dependent <br />on construction scheduling and equipment availability. A minimum of 4.0 feet of suitable cover (2.5 feet) and soil <br />(1.5 feet) material will be replaced on all reclaimed areas, followed by re- seeding with the Rangeland Seed Mixture <br />(Table 55). Reclaimed areas will be managed in the same way as other reclamation, with regular inspections and <br />maintenance to identify and control any excessive erosion, and spraying, as necessary, consistent with the approved <br />Weed Management Plan to control noxious weeds. <br />TC's bond reclamation cost estimate for the CRDA Expansion takes into account the consideration that bond <br />monies have already been posted for the existing Refuse Pile, which includes the entire eastern side (approximately <br />40 acres) that will be redisturbed by the proposed CRDA Expansion. This existing bond (amount corresponding to <br />acres to be redisturbed is approximately $360K), along with the calculated bond coverage for a 50 acre area <br />(approximately $380K), addresses bonding for the initial area of disturbance, as shown on Drawing C -102 in <br />Exhibit 26C. This initial bonded area includes redisturbance of the eastern side of the existing RDA <br />(approximately 40 acres), the initial CRDA bonded disturbance area (approximately 30.3 acres), haulroad <br />disturbance (approximately 2.4 acres), stockpile and ditch disturbance (approximately 9.4 acres), stockpile access <br />corridors (0.4 acres), and a bonded buffer of approximately 7.5 acres to address any minor unplanned disturbances. <br />With a total facility life of approximately 14 to 20 years, it is anticipated that the remaining 50 acres of the total <br />CRDA expansion area of 140 acres will be bonded in two future bond increments of approximately 20 -30 acres <br />each (each increment will be approximately $150K - $230K, depending on size). It is anticipated that Bond <br />Increment I will occur 3 -5 years in the future, and that Bond Increment II will occur 7 -10 years in the future. <br />Consistent with the constraints inherent in a cumulative bonding approach, TC will clearly delineate bonded areas, <br />will limit disturbance to those areas, and will work with the CDRMS to determine and maintain adequate bond <br />coverage for all activities. <br />Concerning the Fish Creek Tipple, no excess spoil or underground development waste will be generated in connection <br />with the operation. Thus, the requirements of this section and Rule 4.09 are not applicable. <br />TR13 -83 2.05 -97.5 05/14/14 <br />
