Il'. Geology - Rules 2.04.5 and 2.04.6(2) The applicant has supplied a description of the geology- of the permit and adjacent areas in Section 2.5 of Volume I of the application. This section has been reviewed by the Divisior, to determine conformance with the Cclorado Rules and Regulations. A general overview of the geologic environment c` the site can be found in the Description of the Environment portion of this document. No development waste will be intentionzlly produced by this operation. P.oof falls will, far the most part, consist entirel._• of coal and will be shipped nut nr will involve a small enough quan,tit~• of material to allow disposal in the mine workings. If any major roof fall occurs which would necessitate disposal outside of the mine, Salt Creek ?fining Compan}• has proposed to dispose of the material at the waste disposal site at the adjacent Dtunger Canyon Dune. The applicant has provided s geochemical analysis of roof and floor material. It is indicated by the data which was supplied that the material is sodic in nature. The pH and sodium z~snrption vatic (SAR) of the material are high relative to preliminary Division standards. These conditions indicate that the material may be substandard as a plant growth medium. D;o problems are indicated b5• the soluble salt contents of the roof and floor material (see Tables 2.1-4 and 2.1-5 of Volume I of the application). The site for the waste disposal pile in D?unger Canyon has not been approved by the Division. Approval of this waste pile is contingent upon the approval of the Munger Canyon permit application. The Division trill not allow placement of any roof fall material at this site until the site has been approved by the Division. For the reasons lust mentioned the follot.*in~ stipulation is necessar}-: ?.

Salt Creek DLning Company has submitted an analysis of the coal to be lined. These data indicate the presence of some elements at higher than normal levels. The Division has determined that there is a very slight possibility that adverse effects to the environment c;ill result due to etipesure of the coal in a surge pile on the mine bench. There are several reasons for this determination.
