RULE 2 PERMITS <br />facing slopes, etc.), techniques such as mulching, chisel plowing, or discing on the contour will be <br />reinstated as necessary. <br />Please refer to Volume 1, Section 2.05.4 for further historical context and discussions concerning <br />mulching reclamation areas on Colowyo reclamation. <br />Irrigation <br />No irrigation is planned for areas to be seeded. <br />Pest and Disease Control <br />Noxious plants, as defined in Section 1.04, will be managed in accordance with the following section — <br />"Weed Management Plan". If insects become a problem to the point where they endanger the successful <br />establishment of the seeded vegetation on the reclaimed area, they will also be controlled using methods <br />suggested by the Colorado State University Extension Service. All herbicides and pesticides utilized will <br />be those that are approved by the appropriate state and federal governmental agencies responsible for the <br />approval and distribution of such agents. <br />Weed Management Plan <br />A listing of Colorado's noxious weeds (A, B, and C lists) as well as Rio Blanco and Moffat Counties' <br />listed taxa are provided in Volume 1, Table 2.05-10 along with indentification of those taxa that have <br />been observed on or near the Colowyo mine and Collom area. As indicated on this table, there are no "A" <br />list taxa known from the area. "A" list taxa must be eradicated. To the contrary, there are seven (7) `B" <br />list (must be managed) taxa known from the environs of the Colowyo mine as well as three (3) "C" list <br />(management may be required by local governments) species. Of these 10 species, common mullein and <br />poison hemlock from the "C" list, and Russian olive from the `B" list are not overly problematic and will <br />normally not require attention. In fact the Russian olive was purposefully planted in previous Colowyo <br />reclamation. If "infestations" of common mullein or poison hemlock evolve, they will be treated in the <br />same manner as the more problematic species. <br />The remaining seven species: hoary cress, musk thistle, Canada thistle, bull thistle, houndstongue, black <br />henbane, and downy brome (cheatgrass) will be the primary focus of the program and will likely receive <br />attention as appropriate in the Collom area. Of these seven species, the first six will be specifically <br />targeted for remediation while the seventh, cheatgrass, will be carefully monitored to determine if it <br />becomes problematic in older reclamation'. If it becomes problematic, it will receive similar attention as <br />the other six species. In addition, continued monitoring of reclamation will focus on identification of any <br />new noxious weeds. <br />For the most part, noxious weeds observed on or near Colowyo reclamation do not achieve "infestation" <br />levels. By infestation, Colowyo means: 1) relative cover contribution of one noxious weed species or a <br />combination of noxious weed species exceeding three percent in a revegetated stand; or 2) a "patch" of <br />any listed species in which the noxious weed component exceeds 25% relative cover and occupies an area <br />larger than 100 square feet on any disturbed area. Rather, noxious weeds tend to occur as scattered <br />individuals or small pockets of individuals. This distribution suggests that spot control will be the only <br />effective procedure that can be utilized. <br />. Although it cannot be discerned with 100% certainty, it appears that cheatgrass patches and populations in Colowyo <br />reclamation, tend to succumb to successional pressure exhibited by the adapted perennials. In this regard, it appears that <br />cheatgrass populations drop off to low levels in mature reclamation. <br />Collom — Rule 2, Page 98 Revision Date: 11/16/16 <br />Revision No.: MR -166 <br />
