General Information for City of Salisbury WWTP
(Grant Creek Treatment Train and Town Creek Treatment Train)
January — December 2019
City of Salisbury WWTP consists of two treatment trains. Effluents from the
Grant Creek treatment train 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.
The Industrial Waste Survey for both treatment trains was conducted in
2019 and approved by PERCS on December 10, 2019.
The Long Term Monitoring plan was approved by PERCS on May 29,

City of Salisbury WWTP
NPDES NC0023884
Long Term Monitoring Plan
Revised May 1, 2018
PERCS Approved May 29, 2018
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 WWTPs 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 grab samples at point in 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(WQ0001956)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.

An Authorization to Construct request was received June 15, 2015 for
installation of two 7,000 gallon reactors and twelve 20,000 gallon raw
materials and waste tanks. The final plans and specifications were reviewed
and approved. Authorization was granted for installation July 14, 2015.
2016 update, One of the (two) 7,000 gallons reactors was brought on-line,
and seven of the (twelve) 20,000 gallon raw materials and waste tanks were
installed and in place--- with four of those in-service. 2017 update: Both
7,000 gallon reactors are now on-line, and seven of the (twelve) 20,000
gallon raw materials and waste tanks are installed in place---with five of
those in service. 2018 update: Of the (twelve) 20,000 gallon raw material
tanks, IPC currently have 6 tanks in service, one installed and not yet in
service, and 2 additional ones that have been awaiting commissioning.
Total of 9 tanks. 2019 update: 8 of the 12 raw material tanks are in service.
IPC requested approval to temporarily install a Diffused Air Flotation (DAF)
unit for a trial study on April 17, 2019. City approval granted April 18, 2019.
If trial study proved successful, IPC will request an Authorization to
Construct to permanently install the DAF unit adding to their current
pretreatment wastewater system.
An Authorization to Construct request was received on June 5, 2019 to
install a 2nd Flaker Line in their production process which would generate an
additional 2000 gpd of wastewater. This flaker unit is an exact duplicate of
an existing flaker line already in production. City approval was granted for
installation on June 7, 2019. Construct of the 2nd Flaker line is now
complete and operational.
The IUP was modified on August 8, 2018 and expires September 30, 2022.
This SIU manufactures surfactants and emollients for the personal care
industry.
