Cortney -

Our monitoring folks don't agree with making the suggested changes because we did not get any public comments to support the change in the area source rule. Call Mary (919-541-5025) if you need a more detailed explanation.

Jim/I are working on your major source issues.

Hi Jim,
Below are a couple of interagency comments that have come in today on this afternoon's drafts:

Major Source Rule.
Page 198. For consistency with equation 10, we believe the symbols X1 and Y1 in equation 11 should be small x prime (small x with a bar over the top) and small y prime (small y with a bar over the top). (Rephrased version of comment that was submitted by the SSC on 18 December 2012.) As an aside, in equation 10, perhaps X1 and Y1 should be Xi and Yi since it is a summation equation from i to n.

Area Source Rule. 
Consider revising the definitions of 10-day rolling average and 30-day rolling average in the area source rule to be consistent with the major source rule to incorporate the 240 hour and 720 hour of valid operating data criteria, respectively. Both rules should probably exclude hours during startup and shutdown as well as unit down time, from the rolling average calculations. 

Regards,
Cortney

Cortney,

Please replace the redline version I sent you earlier this afternoon with this version. A few edits were made to the fourth year language on pages 26 -28.
