0 <br />July 16, 2018 <br />Page 2 <br />Groundwater section of the RN -07 Findings Document to correctly define and discuss <br />alluvial groundwater for the Colowyo Mine. <br />Additionally, the Division states, "the Division concludes that the Colowyo Mine has the <br />potential to negatively impact alluvial groundwater. Therefore, Colowyo has established <br />three groundwater points of compliance for the Mine at MC -04-02 (Collom Gulch), <br />MLC -04-01 (Little Collom Gulch), and MJ -95-01 (West Fork Jubb Creek)." While the <br />Division is correct that Colowyo has established those three points of compliance wells, <br />the Division needs to revise this statement, as approved under TR -109, there are not any <br />AVFs present on the drainages that contain those points of compliance wells. The <br />Division's discussion on in this section needs to be specifically tailor to Good Springs <br />Creek as Wilson, Jubb, and Collom Gulch as approved under TR -1019 have been <br />determined to not be AVFs. <br />3. Section VI. Use of Explosives — Rule 4.08, Page 43. The Division quotes "...the Paul <br />Routsen residence...", while at the time this was correct the property has since been sold. <br />It may be appropriate to update the narrative to state, "the Cannon Family Partnership, <br />LLLP property (formally owned by Paul Routsen)". Additionally, the Division needs to <br />add language to the findings document to denote the pre -blast survey offerings included <br />in Volume 20, Exhibit 14 Item 8. <br />4. Section VII. Disposal of Excess Spoil — Rule 4.09, Page 44. The last full paragraph of <br />this section, the Division states, "...the Division found that the proposed West Pit and <br />Section 16 excess spoil fills were designed in compliance with the requirements of Rule <br />4.09.2." While this statement is true, the word "proposed" is incorrect and should be <br />remove. Both fills have been constructed and stable for a long period of time. The <br />Section 16 Fill has been Phase III release also. <br />S. Section X. Slides and Damage — Rule 4.12, Page 44. The Division states that slides have <br />occurred within the permit boundary, and that they have been reclaimed as appropriate. <br />It is unclear what the Division is referring to. In Volume 1, Section 4.12 one slide that <br />did occur along the haul road is documented. No other slides within the disturbance <br />boundary have been documented and/or mitigation/reclaimed. Some natural slides have <br />occurred within the permit boundary, prior to mining, but none have occurred that have <br />required Colowyo to reclaim them. The Division needs to update this narrative in <br />accordance with Volume 1, Section 4.12 for accuracy. <br />6. Section XII. Backfill and Grading — Rule 4.14, Section C. Approximate Original Contour, <br />Page 46. The Division incorrectly cites "Colowyo Land Management Company" as the <br />property owner for Colowyo deeded surface in the last paragraph on the page. Please <br />revise this to "Colowyo Coal Company L.P." <br />AN EQUAL OPPORTUNt1Y/AFFIRMATIVE ACTION EMPLOYER <br />A Touchstone Energy' Cooperative <br />
