The Division and TCC have been working together to assure that page revisions include all previously <br />approved text, and previously approved revisions are not lost during subsequent revisions. Most of the <br />revised pages submitted with TR66 retain previously approved revisions. Several pages appear to have lost <br />some text. Please assure that previously approved text is retained as appropriate: <br />a) Page xii was incorrectly numbered "ix" This page has the Table of Contents for Volume R-E. <br />Please resubmit this page with the correct pagination. <br />b) Page 2.05-45.6f, TR62 revised text has been retained but TR61 text has been lost. Please reinstate <br />text approved during TR61 approval. <br />c) 2.05-45.6g the last sentence is cut off after, "the engineering soils characterization by" and the text <br />does not flow to page 2.05-45.6h. Please include the portion of text that has been left off. <br />d) 2.05-45.7 information regarding the 7 North escape shaft information has been retained, but TR61 <br />information regarding the 6MN reservoir has been lost. Please reinstate the 6MN reservoir <br />approved text. <br />e) 2.05-84.4 does not fit with TR61 revised pages. Please assure that information from page 2.05- <br />84.3 flows onto the TR66 revised pages. <br />f) 2.05-84.5 does not fit with TR61 revised pages. Please assure that previously approved text is not <br />lost. <br />6. Please refer to Exhibit 3, Pond 1 and Pond 2 Design Detail Sheet. The following inconsistencies were <br />noted. Please review and correct as necessary. <br />a) Pond 1 cross section C-C' and longitudinal profile D-D' are improperly located on the wrong side of the <br />embankment on the plan view. <br />b) Pond 2 longitudinal profile F-F is not properly located on the plan view. (should be E-E'). <br />c) Pond 2 longitudinal profile G-G' (actually a cross section through the pond) is not properly located on the <br />plan view (should be F-F'). Cross section G-G' is the cross section of the emergency spillway of pond 2. <br />d) Inconsistent use of the term longitudinal profile as opposed to cross section. <br />e) The longitudinal profile through the 18 inch riser has no label. <br />The Division's proposed decision date is scheduled for May 10, 2009. Submittal of the requested information in <br />advance of that date will allow for the Division to review TCC's response and make a decision within the regulatory <br />time frames.
