General Information for City of Salisbury WWTP
(Grant Creek Treatment Train and Town Creek Treatment Train)
January — December 2022
City of Salisbury WWTP consists of two treatment trains. Effluents from the
Grant Creek and Town Creek treatment trains are disinfected at each train
then combined and dechlorinated at the Yadkin Effluent treatment train,
which is located downstream of Grant Creek treatment train before being
discharged at Outfall 001 into the Yadkin River. Chlorine is primary
disinfection followed by dechlorination.
Design flow of the Grant Creek Treatment Train is 7.5 MGD, Town Creek
Treatment Train is 5.0 MGD and the City of Salisbury WWTP is permitted
at 12.5 MGD.
The Headworks Analyses for Grant Creek and Town Creek Treatment
Trains were approved on February 22, 2018.
Currently, the updated Headworks Analysis has been submitted to DWR.
DWR has acknowledged receipt on September 20, 2022.
The Industrial Waste Survey for both treatment trains was conducted in
2019 and approved by DEQ on December 10, 2019.
The Long -Term Monitoring plan was approved by DEQ on June 22, 2022.
The Sewer Use Ordinance was approved by PERCS on January 10, 2013
and adopted by City Council on August 20, 2013.
PERCS approved the Enforcement Response Plan on June 17, 2013 and
adopted by City Council on August 20, 2013.

Long Term Monitoring Plan
Revised April 1, 2022
Sampling Points and Frequencies:
Salisbury has a unique situation in that we have two Treatment Trains at two separate physical locations
that the SIU's discharge into. The chlorinated effluent from the Town Creek Treatment Train (TE) is
combined with the Grant Creek Treatment Train chlorinated effluent (GE). The combined chlorinated
effluents (YE) join together on the Grant Creek property are dechlorinated, then flow through cascade
aeration, and then discharge into the Yadkin River. Although not permitted as separate WWTPs, Town
Creek and Grant Creek Treatment Trains will be treated as separate W WTPs in the LTMP with data from
both sites used to determine pollutant removal efficiencies and plant inhibition thresholds.
All SIUs and Locals are monitored per IU Permit requirements and all POC's once per year. The City
uses a Yearly Monitoring Plan. The Plan is followed as closely as possible weather permitting. If an SIU
is not monitored in the month indicated, it is monitored as soon as possible.
Uncontrollables are composite and/or grab samples at points in the collection system that serves
residential, commercial (including dentists and other medical), and any unpermitted non-SIUs.
Uncontrollable sampling, though not required, will be monitored annually.
Salisbury will use the actual sludge that is disposed of as our sludge sampling requirement per our sludge
disposal permit (W00001956) and EPA 503 regs.
Grant Treatment Train
GR — Grant Influent (sampled post preliminary processes, prior to residual side streams and primary
process).
GE — Grant Effluent (sampled at end of chlorine contact basin)
GAB — Grant Aeration Basin (sampled prior to influent of secondary clarification, due to accessibility)
GS - Grant Sludge to Disposal (digester sludge to disposal, sludge taken at end of belt press)
Town Treatment Train
TR — Town Influent (sampled post preliminary processes, prior to residual side streams)
TE — Town Effluent (sampled at end of chlorine contact basin)
TAB 1 — Town Aeration Basin # 1 (sampled at effluent end of aeration basin)
TAB2 — Town Aeration Basin#2 (sampled at effluent end of aeration basin)
TS - Town Sludge to Disposal ( digester sludge to disposal, sludge taken at end of belt press)
Final Effluent (Yadkin Effluent)
YE — Grant and Town Creek Treatment Trains chlorinated combined effluents are dechlorinated then
composite sampled prior to the cascade.

SNC: None
Orders: None
Authorization to Construct: One
An Authorization to Construct request was received on October 26,
2020 and approved by the City of Salisbury on October 28, 2020 for
the construction of a Groundwater Pretreatment System Unit.
UPDATE 2022: This Construction is still on -going.
Missed Data: None
NOTE: City monitoring for Organics were collected Nov. 9, 2021. Due to the
contract lab (Pace Analytical) staffing shortage/error, 8270 samples
were analyzed out of holding time and results were deemed invalid.
The contract lab's staff shortage would not allow a resample in
December (Note: this lab is the only Pace Lab that performs the GPC
cleanup due to Nouryons' wastewater matrix). Organics will be re -
sampled by The City in February 2022.
UPDATE 2022: The City of Salisbury collected the TTO's, as
described above, on February 3, 2022 receiving analytical results on
March 16, 2022. The organic results were judged as compliant.
