Technical Revision No. 55 (TR-55) Adequacy Review
Dear Mr. Gubka:
The Colorado Division of Reclamation, Mining and Safety (Division) has reviewed
Western Fuels-Colorado (WFC's) TR-55 application submitted for proposed changes to
the revegetation plan. The Division has the following adequacy review comments.
1. The cover letter to the TR-55 application states that TR-55 solely covers the
change in success standards for irrigated pasture from a standard to a reference
area, with the exception of the inclusion of a proposal to include interseeding as a
husbandry practice for irrigated cropland.
Based on our review, there appear to be certain other changes included in the
application, including acreage of various postmining vegetation types, detail
regarding sampling protocol and statistical assessment for revegetation success
demonstration, and various other changes. However, it is clear that only a portion
of the concerns addressed in the Division's Technical Revision No. 54 (TR-54)
adequacy review letter dated November 21, 2006 were addressed in the TR-55
submittal. Some of the concerns related to Vegetation Information, Premine and
Postmine Land Use, and the Revegetation Plan were addressed in TR-54 response
submittals, some are addressed in the current TR-55 application, and we are aware
that WFC is planning to submit a separate revision application (TR-56) to address
remaining issues.
In order to ensure and document that all issues identified in the November 21,
2006 adequacy letter (from TR-54) have been addressed, we have the following
request. Please include an introductory section with the TR-56 submittal,
providing an item by item response to each of the adequacy issues listed in
the November 21, 2006 adequacy letter (Items 1 through 28). Within the
response, identify items that were addressed and approved within TR-54 (if
