Hi Ross,
Please contact Bethany for comments related to the Buck CTCC facility, and Rick Riddle for comments on the Buck Steam
Station. These two have the assignment to draft the respective permits.
I'm happy to continue to contribute based on the fact that I compiled the questions, and on my visit to the site, but the
work of drafting the permits is now on their desks.
Thanks,
Ken

Ross, Steve
Thanks for the information on the Buck facility. We have reviewed the submitted info and have a few
clarifications/questions. I have attached the spreadsheet you sent with an added column on the right with our
clarifications/questions included.

Ken,
Attached are Duke's responses (see Excel file) to your questions and concerns below. We are working on updating the
Buck Steam Station stormwater map to reflect the newly identified outfalls. We will pass that along when it becomes
available. Please let me know if you have any further questions.

Hi Steve,
Thanks for your assistance at Buck earlier this month. While there we discussed additional information and
confirmation needs to help us eventually process the two permit applications in hand.
General permitting: During our discussions at Buck I think we agreed to separately process both in-house applications,
one for the Steam Station, and one for the CTCC station. Please confirm that at this time it is still Duke's intent to permit
both facilities separately for stormwater discharges.
Buck Steam Station
• Please confirm the list of the site stormwater outfalls, and expand the list if necessary to fully identify all the site
outfalls. Provide updated site maps indicating any additional features:
o Immediately northeast of SWO02 there appeared to be one or two additional outfalls, apparently previously
unidentified.
o Along the river bank in the vicinity of outfall SW056, and continuing east to SW073 it was not clear that all outfalls
have been positively identified.
• Please provide information on the size of the storm that would cause an overflow or bypass from the Yard Sump.
• Please refresh us on the status of the paired oil traps (north of the boat house) wrt any potential for discharges
from them. Although we discussed them while visiting, I can't recall the comments made about them.
• Please refresh me on the flow in SW002. My meeting notes seem to indicate that Duke reports a dry weather
flow in that outfall.

Buck CTCC Station
• It appeared that there may have been some recent changes to the drainage features not reflected in the site maps
we currently have in hand. The drainage features and contributing areas east of the Admin/Control Building around the
entrance gate and CB40 are unclear to us. In the same general vicinity there appeared to be an additional manhole
south of the cooling towers not shown on our drawings. Please provide expanded and updated drainage maps that
show the full extent of all site stormwater drainage.
• We need additional information on the pipe and drainage system that carries drainage from around the ash basin
into the catch basin that then flows to the stormwater pond. Hs this been submitted in the wastewater
application? Can this flow be removed from the stormwater drainage at the CT site?
• While on site there was some confusion as to the ultimate destination of the water discharge from the o/w
separator immediately south of the steam turbine building. Please confirm that that flow does/does not go to the
stormwater drainage system.
Thanks for your assistance Steve. Please contact me with any questions.
Best Regards,
Ken
