I have personally examined and am familiar with the information submitted in these documents and

information reported therein, I believe that the submitted information is true, accurate, and complete. I am
aware that there are significant penalties for submitting false information.
I trust you will find everything in order. If there are any questions, please contact me at [phone].

Other Information
Dental Amalgam Rule Update
According to the NC Dental Board, in 2019, 43 licensed dentists are in the City of
Burlington's service area. Some of the dentists on this list have dental facilities that are
located outside the City of Burlington's service area, closed, or do not place or remove
dental amalgam.
New dental facilities are provided a One-time Compliance Report form to fill out and
return to the City of Burlington's Pretreatment Specialist. This form is also posted on the
City of Burlington's website.
One-time Compliance Report forms have been completed by and received from 31 dental
facilities.
Emerging Contaminants
Since 2019, the City of Burlington has been working towards reducing the amount of
PFAS being discharged to the East Burlington Wastewater Treatment Plant by surveying
and sampling industrial users thought to be large contributors.
Industrial users identified as having higher than average PFAS in their effluent have been
or are planning to reduce PFAS loading by using product substitution and/or closed -loop
systems.
Fats, Oils, and Grease Program
9 Included on following page

February 13, 2023
Robert C. Patterson Jr., P.E.
Water Resources Director
Subject: Progress of the Fats, Oil & Grease Program
• The City of Burlington's Fats, Oils and Grease Program was implemented as a
two-phase program December 15, 2000. Phase I consisted of a cooperative effort
relying on the participation of the food service establishments (FSEs). Beginning
January 01, 2001 all food establishments that have grease traps or interceptors are
required to maintain pumping records on site.
• Identified FSEs must maintain an annual pumping schedule and are required to
keep records that identify who performed the pumping or clean out, when it was
done, and where the waste was disposed.
• The City of Burlington will be implementing FOG management software to better
monitor the compliance of the FSEs. This software will allow FSEs and their
haulers to upload grease trap service records directly to the City.
In -person inspections for O&G interceptors (grease traps, pits or under counter
units) are focused within the areas of historically high incidence of sewer
overflows and then inspections expand to include the remaining FSEs. These
inspections have addressed employee education in regards to grease disposal
techniques, record keeping, and proper maintenance of grease traps or interceptors
if present. In 2022, 36 FSE pumping records were received and reviewed.
• The City of Burlington City Council approved a fee schedule that includes a
$30.00 fee for Fats, Oils and Grease inspections.
• A program for the Alamance-Burlington school system consisting of 17 school
cafeterias is being implemented.
The City of Burlington's efforts to reduce residential Fats, Oils, and Grease into
its sewer system consist of educational information inserts added to customer's
water bills and information being published in the City's quarterly publication
"City Works".

Dear Ms. Ding:
Due to an elevated level of non -target organic compounds present in the above referenced
sample, we were unable to achieve lower detection limits for volatile and semi -volatile
organic analysis. This sample rewired x1000 dilution for semi-volatiles and x100

City of Burlington
Main Program Permit (NPDES) #NC0023876 / South Burlington WWTP
Secondary (NPDES) #NC0023868 / East Burlington WWTP
Alamance County
Dear Mr. Patterson:
On 8/18/2022 a Pretreatment Compliance Inspection (PCI) was performed by Tricia Lowery of the
Winston-Salem Regional Office. Kristi King was present for the inspection. The purpose of this
inspection was to determine the effectiveness of the Town's pretreatment program, which includes
reviewing the files, POTW plant performance, industry monitoring data, and adherence to the
enforcement response plan (ERP).
Background
South Burlington WWTP (NC0023876) and East Burlington WWTP (NC0023868) are both a 12.0 MGD
permitted facilities. The City of Burlington has 12 Significant Industrial Users (SIUs), 2 of which are
categorical. Of the 12 SIUs, South Burlington has 7 SIUs discharging to their facility and East Burlington
has 5 SIUs (2 categorical) discharging to their facility.
POTW interview
There are no plant problems related to pretreatment issues. One SIU was SNC for zinc in the first 6-
month period of 2021: Indulor. Notices of Violations were issued, in addition to a civil penalty for zinc.
The facility was back in compliance for 2' 6-month period.
Pretreatment Program Elements Review
The Headworks Analysis (HWA) renewal was submitted 3/17/2020 and is still awaiting approval. The next
HWA due will be determined once current submittal is approved.
The IWS renewal was submitted 7/1/2021 was approved on 8/10/2022. The next IWS is due 8/9/2027.
The Sewer Use Ordinance (SUO) was submitted on 12/5/2013. The last SUO approval date was 3/1/2013.

(2/year).
Industrial User Permit (IUP) File Review
A review of the file for Engineered Controls (#0019) revealed that the monitoring data was well
organized and compliant.
A review of the file for Carolina Hosiery Mill (#0055) revealed that the monitoring data was well
organized and compliant.
A review of the file for LabCorp (#0066) revealed that the monitoring data was well organized and
compliant.
The slug/spill control plan for Engineered Controls (#0019) was in good order.
The slug/spill control plan for Carolina Hosiery Mill (#0055) was in good order.
The slug/spill control plan for LabCorp (#0066) was in good order.
