Energy Mtne(N¢. 3 Permit Application Adequacy Review
I have completed an adequacy review of the geology, ground and surface
hydrology, probable hydrologic consequences and alluvial valley floor
of Colorado Yampa Coal Company's (CYCC) permanent program mining and
reclamation permit application which was submitted to CMLRD on January
1984.

The following is a list of notes taken during my review, organized according
to each subtitle discipline, as they would appear in a findings document. The
numbered comments under each subtitle discipline refer to comments that should
be addressed to the applicant as an adequacy concern.
V. Geoloav - Rules 2.04.5 and 2.04.6
A detailed description of the geology of the proposed permit area and adjacent
area is contained under Rule 2.04.6, Volume 1 of the permit application.
Additional information on the geology of the permit and adjacent area is shown
on Map 2, Mine No. 3 Geology, Map 3, Geologic Cross-Sections, Exhibit 1,
Tables 1,2,3,& 4, and Figures 1 and 2.
Results of chemical analyses of overburden samples from the Energy No. 3 Mine
are presented in Table 4, Overburden Chemical Data. The applicant has
included overburden geochemical analyses from 5 drill holes within the
proposed permit area; geographic and vertical sampling density are in
accordance with State guidelines for overburden geochemistry. No
acid-forming, toxic-forming or alkalinity producing materials have been
identified.
A minor concern is that no data are available in the permit application on
chemical analysis of the Lennox coal seam. This coal seam, which is known to
be somewhat high in pyritic and organic sulfur content in the Twentymile Park
Basin, occurs 1n the western portion of the area to be surface mined, and will
be spoiled with the overburden. Given the small quantities of the Lennox coal
