7. Section XXII. Operations on Alluvial Valley Floors — Rule 4.24, Page 53. The Division's
citations to maps in the permit is incorrect. Map 7 and 1 I do not exist in the PAP.
Maps 11, 12, 12B, and 12C do not document the AVFs as stated by the Division. Please
revise.
8. Section XXII. Operations on Alluvial Valley Floors — Rule 4.24, A. Designation of
Alluvial Valley Floors, Page 54. The Division denotes several drainage inside and
outside of the permit boundary that the Division's states have been determined to be
AVFs. In this statement the Division did not take into account the change in AVFs
approved under TR -109. The Division needs to remove the references to Wilson Creek
and Jubb Creek and update all references to Map 11 A as the permit does not contain a
Map IIA.
9. Section XXII. Operations on Alluvial Valley Floors — Rule 4.24, A. Designation of
Alluvial Valley Floors, Page 54. The Division denotes "proposed future operations" on
portions of Good Springs Creek. Those words should be remove and the wording
"current operations" should be inserted as no propose future operations are currently
permitted within the Good Springs Creek watershed.
10. Section XXIT Operations on Alluvial Valley Floors — Rule 4.24, B. Primary Impacts,
Page 55. The section is incorrect and needs to be updated based on the revised AVF
determination permitted and approved under TR -109.
11. Section XXII. Operations on Alluvial Valley Floors — Rule 4.24, C. Secondary Impacts,
Page 55. Please see comment 1 has it pertains to AVFs on Wilson Creek. The section of
the findings document needs to be complete updated as Wilson Creek area adjacent to the
Gossard Loadout has been determined not to be an AVE Also, the Gossard Well needs
to be noted as a monitoring well and not an alluvial well with the revised AVF
determination approved under TR -109.
12. Section XXII. Operations on Alluvial Valley Floors — Rule 4.24, D. Specific Findings
Required by Rule 4.24, Page 56. The section is vague and not entirely correct since the
approval of TR -109. Please update to be more specific to the currently approved
monitoring program and AVF determination approved under TR -109.
Tri-State appreciates the opportunity to provide these comments on the RN -07 proposed
decision, and if you should have any additional questions please feel free to contact Tony
