-.,n- pages 1-10 of the "Blue Dook", to determine monthly rental cost. The applicant proposes using a Caterpillar D-9 dozer, G37D scraper, and a 14-G grader to do all reclamation work, except seeding and mulching, which is contracted out. The r_ost per equipment hour was determined by summing the monthly equipment rental - hours worked per month, the hourly operating cost ("Blue Book") and the operators' wages. Production figures were determined using the CATERPILLAR PERFORhfANCE HANDBOOK, 1980 CAT publication. Altitude and job efficiency adjustments were made to produce final hourly production estimates. Job efficiency was estimated by the method shown on page 411 -of the "Cat Book", which shows that night shifts are 75o efficient and day shifts are 83% efficient. The average of 79o efficiency +das used for all equipment produc- tivity. The altitude adjustment figures were made using the altitude destiny information on page 500 of the "Cat Book". All equipment used on the site was Berated to 940 of initial rating. Efficiency loss was assumed to be equal to the altitude Berating loss. The final efficiency was estimated to be the product of job efficiency and the percent of horsepower deration (74.25%a = 99a (horsepower rating) x 79~ job efficiency). It was assumed that the portion of the haul road wY+ich will serve as access to the M6T well will remain after mining. This assumption is valid, as there is at present no other access to the well. The estimate includes the cost of removing all sediment ponds, fences, structures and roads, except the portion of the M6T access road whicl+ will be left after mining. XXI. Sealing of Drilled Doles (2.05.4(2)(8), 9.07) According to Volume I, page 66 of the permit application, Wyoming Fuel Company agrees to seal drill holes which are not being used for water monitoring, in accordance with Section 9.07.3 of the Regulations. There is no evidence from .site inspection by Division personnel that Wyoming Fuel Company has ever failed to satisfactorily seal an exploration drill hole. The application is in compliance. XXII. Subsidence (2.06.5(6), 4.20 The proposed mining method is totally surface mining. Therefore, this section con- cerning subsidence does not apply and no written findings are necessary. Information supporting this conclusion can he found in Volume I, page 104. XXIII. Special Categories of Pfini.ng The applicant proposes no activity which comes mu7er the heading of Special Categories of Mining. XXIV. Piscellaneous Compliance (7..05.6(5), •1.02, 4.12, 4.19, 4.21, 4.28, 4.30) None of the sections of miscellaneous compliance apply to the proposed operation, except for the requirement for signs and markers. The operation is in compliance at the site with the requirements for signs and markers.
