Emerging Contaminants
19 Kv
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.
The following industrial users have been identified as having higher than average PFAS
in their effluent and have reduced or plan to reduce PFAS loading:
o Shawmut Park Ave, LLC
■ Stopped using chemicals that contained any PFAS as of February 1',
2023
■ SIU permit has been updated to require PFAS monitoring and
implementation of a PFAS Minimization Plan
o ITG Burlington Industries LLC-BHF Plant
■ Submitted a PFAS Minimization Plan which is currently being reviewed
■ Implementing a closed -loop system to minimize PFAS in the effluent
■ Developing non-PFAS containing repellants
■ Goal is to phase out all remaining use of PFAS in the repellency process
by January 1, 2025
141 Dioxane
• In July 2023, Burlington identified elevated 1,4 Dioxane concentrations in the South
Burlington Wastewater Treatment Plant (SBWWTP) effluent.
• In August 2023, Apollo Chemical was identified as being the main contributor of 1,4
Dioxane being discharged to the SBWWTP.
• Apollo Chemical is working with the City of Burlington to reduce 1,4 Dioxane loading.
o Apollo Chemical will be permitted as a Significant Industrial User, and the
permit is currently in review.
o The permit will require 1,4 Dioxane monitoring and implementation of a 1,4
Dioxane Minimization Plan.
Fats, Oils, and Grease Program
• Included on followingpage

February 14, 2024
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 2023, 79 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".
