FACILITY OVERVIEW:
This facility treats domestic waste from a subdivision serving a 723 homes. The facility has a permitted flow of
0.385 MGD and as built flow rate of 0.2 MGD. Expansion to 0.385 MGD will require an Authorization to
Construct (ATC) from the Division and construction of the expanded system in compliance with the ATC. The
current treatment system includes the following wastewater treatment components:
• Equalization basin with dual pumps
• Bar screen
• Flow splitter box
• Dual aeration basins
• Dual clarifiers
• Liquid chlorination
• Chlorine contact tank
• Liquid dechlorination unit
• Post aeration chamber
• Aerobic sludge holding digester
• Stand-by emergency generator
• Tablet chlorinator & dechlorinator (back-up)
The outfall location shown on the 2016 renewal is not consistent with previous permits and does not look
reasonable given the location of the treatment plant. The permitee was requested to verify the location of the
WWTP and outfall and provided a map and updated coordinates. The location has been corrected in the draft

permit and updated in BIMS. The WWTP location coordinates were also updated in BIMS based on the
information provided. BIMS also had the wrong segment of Belews Creek attached to the outfall location. This
was corrected to 22-27-(2).
APPLICATION
The application does not indicate any changes in the facility or treatment since the last renewal of the permit.
The treatment system is operated by Carolina Water Services, Inc of NC. The annual average daily flow is
indicated as 0.123 MGD over the last three years, so the facility is operating below its designed and permitted
capacity. The original application included form D and EPA Form 1. The applicant has also now provided EPA
Form 2A. The facility also holds collection system permit WQCS00261.
INSPECTION
The most recent NPDES inspection occurred on May 19, 2022. No issues were found and the inspection
indicates the facility is well operated and maintained. The last inspection under the Collection System permit
was January 3, 2019, and there were no violations.
COMPLIANCE:
During the permit cycle this facility has not had any enforcement actions. There have been two (2) NODs and
two (2) NOVs. The main issues in the violations have been with NH3-N limits except for one Fecal violation. The
collection system had two SSOs (2020 and 2021) with the one in 2021 leading to an NOV and enforcement
actions.

Hey Bradley,
So sorry for the delay on this! I had drafted up this email but completely forgot to send it! Everything looks good to me
except the fact sheet --the first paragraph under the Facility Overview seems to be referencing a different facility, as the
design flows and wastewater description don't seem to match up with the application & permit.
Otherwise, it looks good!

Here is another draft permit for your review. I hope to be able to send this one to Public Notice next week if
possible. Let me know if you have any comments or questions. Not much in the way of changes on this one. The draft

came in 2021 and they then had to also supply EPA Form 2A which they just did, so that is in the 2022 folder.

Hi Tony,
I just wanted to touch base on the permit renewal process for this facility — Abington WWTP — NC0060461. I am the
permit writer working on the draft permit. I apologize for how long it has taken to get to this review. I am working on
the process now and have run across a few issues I wanted to mention to you.
A while back EPA required that for facilities like yours we get applications on EPA From 2A. I will go ahead with
the drafting with what I currently have in-house, but can you please complete the attached form and submitted
it back to us as soon as you can. You will need to send in a signed hard copy, but if you can also send me a PDF
version in email I can go ahead with the process.
WWTP and Outfall location. I have attached a Google map showing where our database and last permit located
your outfall. This does not appear to be the right location. I seems the WWTP is further east as noted on the
attached map. Could you please provide us with the coordinates for both the WWTP and the outfall?
The map that you attached to your previous application did not appear to show your facility. In conjunction
with the previous bullet could you also provide a topo map showing the locations.
Thanks for your assistance with these issues.
