Re: APGI Responses to NCDWQ Questions about Yadkin Project DO
Enhancement During Generation Unit Refurbishment/Upgrade
Dear Ms. Kucken,
I am writing in response to questions that were raised by you and Mr. John Dorney
at our meeting on May 24, 2006 to discuss the Yadkin Project relicensing, and more
specifically, APGI's proposed DO enhancement and unit refurbishment/upgrade
program. I apologize for the time it has taken to get back to you with responses, but
we have been focused on the relicensing settlement negotiations and completing an
Agreement in Principle for delivery to stakeholders.
At our meeting on May 24, NCDWQ asked APGI to respond to several important
questions:
1) Regarding the operation of the Narrows development, what portion of the
time does APGI run 1, 2, 3 or 4 units at Narrows during the May - November
time frame?
2) Regarding the proposed refurbishment/upgrade schedule:
a. Can APGI shift the refurbishment of Narrows Unit 2 up to be
completed in 2007, thereby allowing the refurbishment of the other
Narrows and High Rock units to all be shifted forward a year?
b. Why does APGI require 2 years to complete the engineering studies
for Narrows, before unit refurbishments can be done?
3) Regarding the information in support of the proposed schedule, can APGI
provide additional engineering information for the files that supports the
proposed refurbishment/upgrade schedule?
4) Regarding the High Rock TMDL Process, can APGI provide NCDWQ with a
copy of its letter committing funds to the TMDL sampling efforts?
In response to your first question about the portion of time that the Narrows
development operates with 1, 2, 3 or 4 units during the May - November timeframe,
operational records since 1/1/2001 indicate the following percentages: 0 units 27%;
1 unit 27%; 2 units 9%; 3 units 11%; and 4 units 26%. This doesn't answer our 11
question really. I was looking for the percentage of time EACH unit operated and
WHICH units were being operated. I can't tell by the answer if they are operated as
Unit 1 then 2 then 3 then 4
In response to your questions about the proposed refurbishment/upgrade schedule,
we have prepared a more detailed version of the schedule (see attachment) that
reflects much more of the engineering and testing work that has to be done as part
of the refurbishment program, before units can actually be upgraded. As you can n
see, although there are no unit refurbishments/upgrades planned for 2007 and
2008, APGI does have an extraordinary amount of preliminary engineering iesZltt?
??'?
and tests that have to be completed in this timeframe. In short, these are not idle
years. I don't think this answers our questions either.
Also regarding the attached, revised refurbishment/upgrade schedule, we have
adjusted the dates for the refurbishment of the units at Tuckertown and Falls to
match the Proposed Plan shown in Attachment 1 of our March 31, 2006 letter to
NCDWQ. The previous schedule (Attachment 2 of the March 31 letter) had not
been updated to reflect those changes. The work at Falls seems to be convenient
for them, but doesn't address the actual concerns likely to present themselves at
Tuckertown (measured low DO ). This schedule essentially looks like we are willing
to allow them to do what makes business sense (assumed) over addressing water
quality standards.
Regarding additional engineering/design information that can be provided to
NCDWQ in support of the proposed schedule, APGI is willing to submit to NCDWQ
any relevant engineering studies or information done by APGI or its engineering
consultants as this work progresses. However, APGI considers all such information
as proprietary, business sensitive information that would have to be protected as
such by DWQ._ You noted this in your letter to them
Finally, in response to your question about APGI's participation in the High Rock
TMDL process, I recently e-mailed to you APGI's commitment to the planned water
quality monitoring effort which is being done to support model development for the
TMDL process. Attached is a hard copy of that email. The $50K commitment is
great. They have put this kind of money and more on other local things such as
boats for patrolling the lakes etc
Once again, we hope this letter provides you with the additional information that you
were seeking. As always, we thank you for your willingness to continue to work with
APGI on these issues. If you have any further questions, please contact me.
Sincerely,

Gene Ellis
Licensing & Property Manager
