The Division has conducted its preliminary adequacy review of TR-14. Please provide your
responses to the following items by April 29, 1994. For the ease of replacement into the
current Raton Creek application, responses should be formatted as permit application
replacement pages where appropriate.
The proposed decision date for TR-14 is currently scheduled for May 6, 1994. Should an
extension of this decision date be necessary for the purposes of providing the requested
responses, please contact us.

2. Rule 2.04.9(1)(el: Please provide a discussion of the present productivity of soils in
undisturbed areas in the vicinity of the mine site. Please compare this productivity to that

particular the productivity of the areas that will receive only 4.5 inches of topsoil.
3. Rule 2.04.9(3): Should the responses to Item 2 of this letter demonstrate that the 4.5-
inch topsoil replacement depth be insufficient to achieve vegetation sufficient to support a
rangeland use, please discuss how much additional topsoil will be needed, and whether
any overburden materials will be selected as topsoil substitutes or supplements. If over-
burden materials will be used, please provide results of any analyses, trials, and tests
described in Rule 4.06.2.
4. Rule 2.05.3(3): Pages 348 through 356d of the permit application provide a narrative of
