Coio. Dept. of t`latural Resources Colorado Yampa Coal Company (CYCC) is submitting the following informa- tion in response to the CMLRD's Midterm Permit Review letter dated February 26, 1985. IX. Vegetation - Rules 2.04.10, 2.05.4(2)(e), 4.15 1. As noted in the Division's October review letter, a revision has been approved for using a wood chip mulch instead of an annual cereal grain. The revision did not specify the type and rate of mulch which would be applied on areas reclaimed with topsoil from long-term stockpiles (which contain topsoil salvaged prior to roto- clear use and thus, do not contain the wood chip mulch). A plan for mulching (if other than the originally approved annual grain cover) should be submitted for non-rotoclear topsoil areas. RESPONSE: Examination of the original October 13, 1981 submittal to the CMLRD and your response dated December 4, 1981 clearly indicates that the request made by CYCC and approved by the CMLRD was that CYCC would discontinue mulching. The request and approval were not conditional upon the substitution of a wood chip mulch for an annual grain mulch. The revision did in fact specify the soil stabilizing prac- tices to be used by CYCC on all reclaimed areas and not the areas rotocleared as suggested by the CMLRD. Our original revision was based upon a combination of practices which have been used, in- spected and approved by the Division since the fall of 1981.
