-21- The reader is referred to that Findings Document for details of the above conclusions. Proposed changes in the operation since the original permit issuance all involve the lessening of potential impacts to these alluvial valley floors. These changes include: a. Smaller permit area, including loss of coal underlying South Canyon Creek; b. only minimum (15,000 yd3) disposal of coal mine waste on the surface; c. lower maximum permitted coal production, implying less attendant surface activity. The Division finds, based on its previous assessments and written findings, that the proposed operation will not interrupt, discontinue or preclude farming on alluvial valley floors, will not materially damage the quantity or quality of water in surface ar ground water systems that supply the alluvial valley floors, and will be conducted to preserve the essential hydrologic functions of the alluvial valley floors. The proposed operation is in compliance with the requirements of this section. X. Climatological Information and Air Resources - Rules 2.04.8.2.05.4(20(h). 2.05.6(1) and 4.17 These topics are addressed in Section 3.4 of the Permit Revision application. The relevant Colorado Department of Health Air Quality Permits for the mine site are current. The proposed operation is in compliance with the requirements of this section. XI. Topsoil - Rules 2.04.9, 2.05.3(51. 2.05.4(2)(dl, and 4.Ob Baseline soils information is located in Section 3.5 of the application. The soils on the site are considered fair to good growth media. Approximately 63,000 cubic yards of topsoil have been salvaged from the disturbed areas, sufficient to cover the disturbed area with an average of approximately 13 inches of topsoil. The applicant has committed in the reclamation plan to replacing 16 inches of topsoil on the disturbed areas. Due to the apparent shortage of topsoil material in relation to the replacement thickness committed to, the following Stipulation is imposed. STIPULATION N0. 18 WITHIN 180 DAYS OF PERMIT ISSUANCE, THE APPLICANT SHALL RESURVEY ALL EXISTING TOPSOIL STOCKPILES, AND DETERMINE WHETHER A 16 INCH REPLACEMENT DEPTH IS POSSIBLE. IF IT IS DETERMINED NOT TO BE POSSIBCE, THE RECLAMATION PLAN SHALL BE MODIFIED ACCORDINGLY.
