(• Technical Revisions $ <br />TR 48, approved October 14, 2003, <br />pipelines that were installed across <br />irrigation water to downstream users <br />monitoring plan <br />incorporated information regarding 12" and 26" HDPF- <br />the permit area for conveyance of West Lateral Ditch <br />This revision also modified the approved surface water <br />TR -51, approved on August 27, 2004, designated a pre - mining topographic depression as <br />sediment control pond 014. <br />TR 52 approved the design of sediment control Pond 012 and was approved on January 18, <br />2005. <br />TR -53 was approved on September 16, 2005, establishing an area at the Nucla airport to be the <br />reference area for Dryland Pasture. <br />�• <br />The Midterm Permit Review No. 5 (MT -5) was submitted to WFC on November 23, 2005. <br />With MT -5 the Division had a significant number of adequacy questions. Key adequacy <br />concerns included performance bond requirements and the lack of sufficient detail in the current <br />Permit Application Package (PAP) to recalculate the bond liability estimate for the midterm <br />review. Other sections of the PAP that needed to be updated were the hydrologic balance <br />documentation, including probable hydrologic consequences; drainage and sediment control; and <br />groundwater monitoring. The Division requested that WFC submit a technical revision <br />addressing these adequacy concerns by January 31, 2006. WFC prepared Technical Revision No. <br />54 (TR -54) to address the Midterm Review comments, which was received by the Division on <br />April 10, 2006. TR -54 was approved on July 30, 2007 and the existing permit document was <br />substantially updated to include seven volumes of permit application materials. The PAP now <br />combines New Horizon Mine 1 site information with New Horizon Mine 2 into one permit <br />document. <br />At the time of the MT -5 submittal to WFC in November 2005, the Division was still in the <br />Process of reviewing the revegetation plan information contained in the PAP. The Division <br />forwarded an Addendum to the Midterm Review to WFC with revegetation plan comments on <br />December 27, 2005. The revegetation plan changes were finalized subsequent to the completion <br />Of the Review and TR -54 approval. <br />TR was submitted by WFC on November 17, 2007. The revision would have incorporated a <br />new gated pasture reference area, but also included various other proposed changes to the <br />(• revegetation and postmining land use plan that generated substantial concern and comment from <br />W <br />
