RE: Buck follow-up information
Bethany,
The seepage from Manhole #1 has been rerouted. It no longer flows into the combined cycle's stormwater system; it has
been routed so that it eventually flows to the same area as AOW S-09. I believe this was the last outstanding issue for
the combined cycle's ISW permit. If you need any additional information, please feel free to contact me. Thank you.

Thank you, Ross. I was out of the office a few days this week and will close the loop with you on this information
soon. For now the aerial photo will suffice, but I'll get back to you about whether the Stormwater Drainage Site Plan
needs to be revised with that drainage boundary before the permit draft is finalized. Regardless, it is a task that will
need to be completed for the SPPP's Site Overview site map for this facility once under the permit. I'll continue working
on the draft permit and fact sheet for EPA's review, and I'll update you with the status as I'm able.
Thanks,

Subject: RE: Buck follow-up information
Ross,
I wanted to follow up on our conversation earlier this week about Buck CTCC. We can move forward with finalizing a
draft permit for that site; it will need to go to EPA for review before public notice. We don't know if they will take the
full 90 days for review, but we would move forward with the notice as soon as we had their approval. We will send Buck
Steam Station and Buck CTCC at the same time, so that draft permit needs to be finalized too. Buck Steam Station's
draft permit should be close to being ready (Rick Riddle is the permit writer).
For me to complete the draft permit and fact sheet for EPA, I need the following information:
(1) You said one of the engineers determined that none of the toe drains from the ash basins drain into the riprap
ditch in question. Please confirm this finding. That is correct. None of the toe drains from the ash basins drain
into the riprap ditch.
(2) Please verify what the drainage area is to the riprap ditch. We talked about a gravel parking area or laydown
area that had been used during construction. Please confirm and provide a revised drawing to document this
drainage area contribution (it is absent from the 9/14/2011 Stormwater Drainage Site Plan included with the
original application) and current/past activities there. The area to the east of the cooling towers makes up the
majority of the possible drainage area of the riprap ditch; I say possible because this area either goes to the

riprap ditch or drains to another portion of the facility. Either way, the area was used as a staging area for offices
during the construction of the new plant. From the attached aerial photo, you can see it is just a graveled area
atop a hill. The plant has indicated that they do not use that area for industrial activities; that might be why the
area wasn't included in the drainage plan. Will the aerial photo suffice or will the white area of the Stormwater
Drainage Site Plan need to be filled in?
(3) You said that the manhole south of the cooling towers (Manhole #1, which was not sealed) will be re-
routed. Please provide an estimated timeline for that. For the purposes of the draft permit, we will hold final
issuance until that is completed. Given EPA's review time, public notice and 15 day period that follows any
notice, there should be sufficient time to complete this modification. It is difficult to provide a timeline for this
work, mainly because it will involve procuring a dam safety permit. Normally, a dam safety permit takes 90 days
to receive, however, there are a number of projects with varying priority awaiting permits. It is difficult to say at
the moment what priority will be assigned to this project and therefore when a permit will be issued. Once the
permit is issued it is estimated that the work will be complete within 2 months.
If you have any other questions, please let me know.
Best regards,
Bethany

Ross,
I explored the SOC concept with Bradley, and we've concluded it is not a viable option to expedite the NPDES
Stormwater Permit for Buck CTCC while the potential for wastewater discharges to enter the stormwater system exists
there. Normally an SOC is established when a permittee is out of compliance with current permit conditions, and this
site does not have a permit at all yet. That complicates the SOC process from the start. Bradley was in a meeting with
Shannon Langley and Richard Baker earlier this week, and he also conveyed to them that the best option to proceed
with Buck CTCC's stormwater permit is to remove those connections.
It might help to speak more next week, let's set up a time that you, Bradley, and I can talk on a call if that helps.
Best regards,
Bethany

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

Thanks for the information on the Buck facility. We have reviewed the submitted info and have a few

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
