Inspection Summary:
On December 19, 2023, Division of Water Resources staff Kristen Potwora and Caitlin Caudle conducted a scheduled
routine compliance inspection of the Burlington DCAR. Shane Fletcher, Residuals Management Coordinator, was present
during the entire inspection.A review of records, the belt press facility, and residuals storage was completed at the South
Burlington WWTP. This review reflected compliance with the subject permit.
Compost was last made in May of 2020. All residuals from the belt press are currently shipped to McGill. There is no plan to
make compost in the immediate future. Only one digestor at the South Plant is used on a regular basis. There are three
round digestors and two square digestors; all other digestors remain empty. Plant staff typically load waste into the digestor
for a week, and then they will run the belt press for three days.A new belt press was installed the first week of November,
and plant staff alternate between each belt press.Approximately 300,000 gallons of residuals are processed each week.
The pump that sends residuals from the digestor to the belt press is in the basement of Building I, where the digestor is
located. South residuals will be sampled once a year in case they need to be land applied under the Class B permit.
Other observations:
• Synagro manages all field loading records, nutrient and pollutant loading calculations, as well as soil reports for the City.
• Synagro will get a Utilization Agreement from each landowner on an annual basis.
• There are approximately 500 loads of 6,200 gallons in each of the 2 storage ponds at the WWTP. Each storage pond
has approximately one year of storage.
• There is a one acre covered concrete pad that all belt press material is stored on. The immediate dumping area has a
concrete berm that keeps the residuals contained. There is an adjacent berm that is uncovered for additional storage.
• Neither hauling nor application were occurring at the time of inspection.
• Residuals from the WWTP are top loaded on a circle drive at the facility.
• Floor grates all return to the head of the WWTP.
