-z7- <br />The average annual precipitation at the mine site is 14 to 15 inches. The <br />mean annual air temperature is 47oF to 53oF, and the frost-free season is <br />125-165 days. The prevailing winds are easterly. <br />Air resources are under the jurisdiction of the Air Resources Division of the <br />Colorado Department of Health via the emissions permitting process. <br />An initial approval air emissions permit was issued on October 11, 1979 to <br />Dorchester Coal Company. This permit has now expired. Applications for four <br />emissions permits are included as part of Section 2.03.10 of Volume lA and the <br />1st Adequacy Response. The applicant will submit the documentation of final <br />approval for these permits in order to demonstrate compliance with the <br />requirements of Rule 4.17, Air Resources Protection. <br />Additional information was received by the Division on January 28, 1983, which <br />was submitted as Technical Revision - Additional Coal Load-out Area - <br />Dorchester #1. A modified emissions permit, dated September 20, 1982, is <br />included in the January 28, 1983 Technical Revision as Exhibit D(6). <br />The Division finds the operation in compliance with the requirements of this <br />section. <br />X. Topsoil - Rules 2.04.9, 2.05.3(5), 2.05.4(2)(d) and 4.06 <br />Soils resources information, as given in Section 2.04.9 of Volume I, pages 122 <br />through 165, Map Dor-S-S-I, and plates Dor-11 and Dor-12 of the application, <br />has been reviewed by the Division. Additional information is given in Section <br />2.05.3(5) and Map 2.05.3-6 of Volume I of the 2nd Adequacy Response. In <br />general, the available soils are of a sandy loam with no toxic properties. <br />The A horizon from the waste pile area was comprised of soil of excellent <br />physical and chemical characteristics, with the exception of some limiting <br />plant nutrient levels. B horizon soils will also support vegetation, if <br />fertilized. Because some of the area to be reclaimed was previously <br />disturbed, surficial materials were also analyzed. Material within the <br />previously disturbed area also appears to be suitable for revegetation <br />purposes, if amended. <br />The topsoil handling section of the reclamation plan shows the only <br />undisturbed area where topsoil will need to be stripped, is in advance of the <br />waste pile. Topsoil is salvaged in a two-step operation with approximately <br />one foot of A horizon and three feet of B and C horizons being salvaged. Soil <br />material that is not directly redistributed is stockpiled. The stockpiles are <br />located in stable areas, clearly marked and stabilized with a vegetative <br />cover. <br />The reclamation plan is described in Section 2.05.4, pages 187 through 205 of <br />Volume 2 of the application. Additional information is provided in Section <br />2.05.3(5) and 2.05.4 of Volume I of the 2nd Adequacy Response. <br />There is an adequate amount of topsoil and subsoil to place 3 feet of subsoil <br />and one foot of topsoil on the waste pile area, and approximately 7 inches of <br />a combination of topsoil and subsoil on the disturbed areas within the <br />facilities locations. The material is good quality and should serve as a good <br />plant growth medium, when amended. <br />The operation is in compliance with the requirements of this section. <br />
