weed spraying requirements of the past few years, it seems as though MCM may need to <br />spray for noxious weeds on multiple occasions in order to control them. Please review <br />and amend the Noxious Weed Management Plan to include more detailed <br />information regarding the Russian Knapweed infestation that has been noted at the <br />Williams Fork Mines and the Williams Fork Strip Pit and the hounds tongue that <br />has been observed on the site. Please also amend the plan to include more specific <br />detail regarding the timing of the weed spraying and the need for multiple weed <br />spraying during a given season. <br />21. Permit page 2.05 -32a discusses the weed identification, mapping and tracking activities <br />that are associated with the noxious weed management plan. The text gives little detail <br />regarding the method of weed mapping and tracking. Currently, MCM provides some <br />weed mapping and spraying detail on their annual reclamation report map (Reclamation <br />and Building Demolition Map). This map provides unconnected information and the <br />multiple colors and layers create problems in reading the map. Please update the <br />noxious weed management plan to include more detail regarding how MCM <br />performs their noxious weed mapping and tracking programs at the Williams Fork <br />Mines and the Williams Fork Strip Pit, including whether point or area features are <br />mapped, what constitutes a weed patch for mapping purposes, etc. Please add a <br />commitment to the permit to include a separate weed tracking map in the Annual <br />Reclamation Report. This map should show the weed species encountered, their <br />location, the method of treatment and the initial year they were seen at that location. <br />The weed tracking layers can then be removed from the Reclamation and Building <br />Demolition Map currently included in the ARR (although this map, with the <br />reclamation information, will need to remain). <br />22. Permit page 2.05 -32c states that MCM will perform revegetation monitoring in the third <br />year following seeding. Several areas were reclaimed during the 2008 field season, <br />making 2011 the third growing season. MCM is reminded that revegetation monitoring <br />is required for these reclaimed areas this year. Please include the vegetation monitoring <br />report with the 2011 Annual Reclamation Report. <br />23. Permit page 2.05 -33 discusses the reclamation and revegetation plan that will be used on <br />the "No. 9 Portal Area/Refuse Pile ". The No. 9 Mine refuse pile was reclaimed in 2009. <br />Please update the text on permit page 2.05 -33 to include a discussion of how the No. <br />9 Mine refuse pile was reclaimed. <br />Rule 2.05.6(6) — Subsidence Control Plan <br />24. The information contained in this section is out of date with regards to the permit term <br />information and anticipated mining dates. Several of the specific pages where the dates <br />are incorrect are 2.05 -48.1, 50, 51, 52, 53, 63 and 65. Although subsidence monitoring <br />has been discontinued at the Williams Fork Mines (with TR -12 and TR -30), this <br />information still needs to be updated. Please update the permit term information and <br />anticipated mining dates that are listed in the text in the subsidence control plan, <br />which begins on permit page 2.05 -48. <br />Williams Fork Mines C- 1981 -044 <br />2011 Midterm Review (MT -06) -11- 28 June 2011 <br />
