Dear Mr. Thornburg,
The City of Winston-Salem owns and operates three water treatment facilities in Forsyth County; the
P.W. Swann, R.W. Neilson and R.A. Thomas Water Treatment Plants. The Swann Plant currently has a
Class A Distribution Permit (WQ0031314) for the residuals produced. In 2012, the city added the
Neilson and Thomas WTP's as additional generating facilities under the Swann WTP's permit. We are
requesting a renewal of permit WQ0031314 with one exception of a major modification increasing the
R.W. Neilson's generating limit to 2,500 dry tons. This request is due to NOD-2020-PC-3075 where the
Neilson WTP exceeded its current limit of 1,499 dry tons per year (see attached letter from Lon T. Snider
dated July 7, 2020 and Bill Brewer's response dated July 13, 2020). By increasing the permitted dry
tonnage for Neilson, we should eliminate future exceedances if we are unable to haul of-e year due to
rainfall or other issues.
Below is a summary of the documents included in this renewal application package.

Forsyth County
Dear Mr. Brewer:
The Division of Water Resources (DWR) acknowledges receipt of your 2019 Annual Report for the subject
permit. A review of this report was conducted by DWR staff person Jim Gonsiewski. The following
deficiency was noted from the review:
Attachment A of the Permit states that the yearly maximum dry tons to be distributed annually from the Neilson
WTP is 1,499 dry tons. A total of 2,334.69 dry tons from the Neilson WTP were distributed in 2019. This is
an exceedance of 835.69 dry tons for the year.
Please provide a response to this letter within 30 days of receipt by your office indicating the corrective actions
taken to address this deficiency. If you anticipate this condition occurring again, this office recommends that
you apply for a permit modification to increase the permit limit. If this exceedance occurs again without a
permit modification, a Notice of Violation may be issued.
If you or your staff have any questions concerning this letter, please contact me or Jim Gonsiewski at (336)
776-9800 or via email at jim.,-,onsiewski_�i_ncdenr.gov.

Forsyth County
Dear Mr. Snider,
This letter is in response to your Notice of Deficiency (NOD-2020-PC-3075) letter dated July 7, 2020
regarding an exceeciance of the Neilson WTP's permit distribution limit of 1,499 dry tons of residuals.
This hauling event represents residuals generated over a 34-month period for an average annual
production rate of 824 dry tons per year ([2,334.69 DT's _ 34 months] X 12 Months). Lagoon #2 was in
service from January 2016 until April 2017 and lagoon #3 was in service from April 2017 until October
2018. Under normal circumstances at the Neilson Plant, one lagoon is clean and ready for service, one
lagoon is drying and one lagoon is in service. During the 2015 and 2017 calendar years, the Neilson WTP
did not distribute any residuals, which created a "backlog" that was caught up in 2019 by hauling more
than one lagoon. The residuals hauled in calendar year 2019 eliminated any backlog and we have
returned to our normal schedule. In addition we will be applying for a major modification to our permit
for the Neilson WTP requesting a generating limit of 2,500 dry tons to eliminate this from being an issue
should we be presented with the same situation in the future. Our existing permit expires in February
2021 and I am currently preparing the renewal application.
If you have any questions regarding this matter, please contact me at 336-397-7727.

WQ0031314 issued November 30, 2012, and shall be subjeetto the conditions and limitations as specified
therein. Please pay particular attention to the monitoring requirements listed in Attachment A for they may
differ from the previous pexmit issuance. Failure to establish an adequate system for collecting and
maintaining the required operational information shall result in future compliance problems.
Please note the following permit conditions are new since the last permit issuance dated
November 30, 2012:
➢ Condition 111.9. — There are new provisions for the utilization agreement compared to Old
Condition I1I.9., e.g., can be dissolved at request of those receiving residuals or sale of land;
the length of agreement is up to parties concerned, Read carefully.
D Condition II1.13. — Similar to Old Condition III.13., but now if the Permittee knows that those
receiving residuals are over -applying, the Permittee shall report this to the Winston-Salem
Regional Office.
There was a request to remove Condition III.B.h, from the Perinit, i.e., the soil pH requirement.
The laboratory results showed that the pH of the residuals to be applied was less than 6.5. Because the pH
is this low, Condition 111.81, remains in the permit even though it is water treatment plant residual being
applied.

F. WASH WATER AND RESIDUALS HANDLING
1. General.
a. Initial Wash Water and Residuals Handlin 7 . Spent wash water and
filter -to -waste will discharge by gravity to a wash water
equalization basin. The collected water will gravity discharge from
the equalization basin to the residuals storage lagoons. Gravity
flow rates from the equalization basin will be controlled by a rate
control valve.
The wash water drainage system upstream of the equalization basin
will be designed to allow six filters (two treatment trains) to be
simultaneously wasted at the design filtration rate. This drainage
capacity is provided for an emergency condition when water quality
dictates the basins be wasted until necessary treatment adjustments
are made. Because this is an emergency condition and not part of
the normal plant operation, the facilities downstream of the
equalization basin will not be designed to accommodate this
increased emergency flow. Flows in excess of the equalization
basin drainage capacity will overflow to the plant overflow drain.
Unthickened residuals from the sedimentation basins will discharge
by gravity through the viewing pit to the residuals storage lagoons.

residuals to drain to future residuals thickeners when the basin is
converted to a clarifier.
b. Future Wash Water and Residuals Handlin•,. Provisions will be
made to allow the future addition of a dedicated filter -to -waste drain
to a future equalization basin for filter -to -waste recycle. The future
filter -to -waste equalization basin will be equipped with pumps for
recycling to the plant raw water influent piping. The existing
equalization basin will be dedicated to handling filter backwash
water.
Provisions will be made to allow the addition of a second
equalization basin dedicated to filter backwash water handling. The
future wash water equalization basin will be equipped with pumps
to pump wash water to the existing equalization basin which will be
converted to a clarifier for wash water treatment.
Wash water and residuals handling and treatment facilities will be
designed to allow a possible future addition of the following.
• Equalization basins.
• Wash water clarifiers.
• Residuals thickeners.
• Residuals dewatering facilities.

P.W. Swann Water Treatment Plant
Solids Handling Plan
The Swann Water Treatment Plant is a 25.0 MGD water treatment facility. Solids are
generated by sludge removal from two sedimentation basins, backwashing six filters, and
filter -to -waste after filter backwashes are completed. Solids produced from filter backwashes
and filter -to -waste are routed to a flow equalization basin before entering one of two residual
lagoons. Solids removed from the sedimentation basins are routed directly to one of two
residual lagoons. The equalization basin volume is 0.489 MG, and each of the two residual
lagoons has a volume of 3.2 MG.
Permits and Classifications:
1. The discharge from the residuals lagoons is authorized by NPDES Permit NCG590003.
The classification for the discharge is Grade 1 Physical/Chemical.
2. The distribution of the residuals removed from the lagoons is authorized by permit
WQ0031314. The residuals are classified as Class A.
Operation:
1. The system consists of a 0.489 MG equalization basin (EQ basin) and two (2) residuals
lagoons with a capacity of 4.3 MG's each.
2. Routine inspections of equipment will be conducted Senior Utility Plant Supervisor to
ensure proper operation of equipment. Any equipment not functioning properly are
reported through the water division's asset management program, MAXIMO, to the
appropriate support group for repair/replacement.
3. Each lagoon consists of an oval concrete apron, a clay bottom, and an access ramp used
for residuals removal. The solids stream enters on one end of the lagoon and there is an
adjustable weir on the opposing end allowing decant to flow to the discharge.
4. Backwash and filter -to -waste water from the plant process flow by gravity to the EQ
basin. The backwash and filter -to -waste water then flows by gravity into the lagoon in
service. A regulating valve prevents flow spike from entering the residuals lagoons.
5. A flow meter measures flow leaving the EQ basin and 38% Sodium bisulfite is applied to
the EQ basin discharge for dechlorination of effluent being sent out discharge
NCG590003.
6. All sedimentation basin residuals flow by gravity directly to the residuals lagoon in
service.
P.W. Swann Water Treatment Plant
Solids Handling Plan -Permit #WQ031314
Revised 07/14/2020

7. Each lagoon has the capacity to accept and store the solids produced by the plant for
approximately 18 months. This allows one lagoon to accept the daily waste stream of
solids while the other is out of service.
8. Residuals are removed from the lagoons in liquid form and hauled to land application sites
by a private contractor.
Monitoring and Reporting Requirements:
1. Residuals generated by each source -generating facility must be analyzed to demonstrate
that they are non -hazardous based on the most current permit requirements (Attachment
A). Sampling will be conducted under supervision of the Senior Water Treatment Plant
Supervisor by WSFC Utilities current contractor as described below in compliance with
permit requirements.
2. Analysis will be performed by a NC Certified Laboratory.
3. Analyses made according to monitoring and reporting requirements must be certified for
the required parameter(s).
4. Corrosivity, ignitability, reactivity, and a Toxicity Characteristics Procedure analysis are
required once each permit cycle. The TCLP analysis includes the following parameters
(i.e., note the regulatory level in milligrams per liter in parentheses):
Arsenic (5.0)
Barium (100.0)
Benzene (0.5)
Cadmium (1.0)

6. Data to verify pathogen reduction and vector attraction reduction of the residuals is
maintained on file for five years. The required data is specific to the stabilization process
utilized, and is also sufficient to demonstrate clear compliance with the Class A pathogen
requirements and restrictions noted in 15A NCAC 02T .1106 (a) and (b) and vector
attraction reduction requirements in 15A NCAC 02T .1107 (a).
7. Proper records are maintained tracking all residuals activities. These records include the
source, volume, analysis, and recipient of the residuals.
8. Three copies, per application event, of all required monitoring and reporting requirements
are submitted annually before March 1, to NC DEQ-DWQ.
Performance Standards:
1. The pollutant concentrations in any residuals that are land applied to any land application
site shall not exceed the following Ceiling and Monthly Average Concentrations (i.e.

4. Bulk residuals and other sources of PAN (Plant Available Nitrogen) are applied to all land
application sites at or below agronomic rates. Appropriate agronomic rates are calculated
using expected nitrogen requirements based on the Realistic Yield Expectations (RYE)
field cover for each approved land application site.
Spills and Noncompliance Notification:
1. The Winston-Salem Regional Office, telephone number [phone], will be notified
within 24 hours or the next working day following the occurrence or first knowledge of
the occurrence of any of the following:
i. Any occurrence with the distribution program, which results in the land application of
significant amounts of wastes, which are abnormal in quantity or characteristic.
ii. Any failure of the distribution program resulting in a release of materials to receiving
waters.
iii. Any time that self -monitoring information indicates that, the facility has gone out of
compliance with the conditions and limitations of the permit or the parameters on
which the system was designed.
iv. Any process unit failure, due to known or unknown reasons, that renders the facility
incapable of adequate residual treatment.
v. Any spillage or discharge from a vehicle or piping system during transportation of
residuals.
2. Persons reporting such occurrences by telephone shall also file a written report in letter
form within (5) days following first knowledge of the occurrence. This report must outline
the actions taken or proposed to be taken to ensure that the problem does not recur.

2.7 WASH WATER AND RESIDUALS HANDLING
�ua.►� �w�� JliS� c�iati..
S,-L eu,�.� A -as
ZJJ Wash Water and Residuals Handling
The existing wash water and residuals generated at the WTP consist of four main flow streams:
Spent wash water,
Filter -to -waste,
Sedimentation basin residuals, and
Miscellaneous drains.
The existing facilities available to process the wash water and residuals include three residuals
lagoons, a lagoon decant pumping station, and a waste pumping station. The plant currently
recycles the plant wash water and residuals decant to the head of the plant. In this project, the
wash water and residuals handling system will change in the following ways:
Abandon the practice of recycling plant wash water and residuals decant,
Demolish the existing lagoon decant pumping station,
Remove all existing pumps and electrical equipment from the waste pumping station.
Abandon the waste pumping station in place.
Cap all lines that provide flow to the existing waste pumping station,
Construct new wash water equalization basin and wash water clarifier,
Demolish existing inlet and decant structures in residual storage lagoons,
Install new inlet structures in residual storage lagoons to receive residuals from new
hoseless vacuum system and wash water clarifier,
Construct new decant structures in residual storage lagoons and tie discharge decant in
new wash water equalization basin,
The proposed wash water and residuals handling system will consist of a new wash water
equalization basin and wash water clarifier, while retaining the use of the existing residual storage
lagoons. For the proposed wash water handling system, spent wash water, filter -to -waste,
sedimentation basin drain, basin overflow, and miscellaneous drain flows for Neilson and East will
be combined in an existing manhole upstream of the waste pumping station and discharged to the
new wash water equalization basin. Each residual storage lagoon will have a new decant structure
installed which will collect and convey the decant by gravity to the new wash water equalization
basin. Submersible pumps in the wash water equalization basin will pump the collected wash
water flows to the new wash water clarifier. The wash water equalization basin effluent will be
dechlorinated in the force main before discharging to the wash water clarifier. The wash water
clarifier effluent and equalization basin overflow will discharge to the creek in accordance with the
existing NPDES permit.
The wash water drainage system upstream of the wash water equalization basin will be designed to
allow one filter to be wasted while one filter is backwashing at the design filtration rate. In
addition, continuous flows from the miscellaneous drains will be discharged to the wash water
equalization basin.
BLACK & VEATCH I Civil and Process Mechanical Design Memorandum 2_26

Winston-Salem/Forsyth County Utility Commission I DESIGN MEMORANDUM
Residuals collected from the track vacuums and wash water clarifier will discharge by gravity to the
existing storage lagoons in new inlet structures.
Operations of the lagoons will not change in this project to maintain existing redundancy in the
residuals storage lagoons. The existing system consists of three lagoons that are rotated for storage
on an annual basis. Throughout the year, one lagoon receives residuals from the plant while the
previous year's residuals air dry in the other lagoon. The third lagoon is offline and acts as a
standby available for emergencies. In the lagoon that is operating, residuals are thickened
throughout the year, and decant and overflow are discharged to the existing equalization basin.
When a lagoon has reached its storage capacity at the end of the year, it is taken off-line for
approximately one year and allowed to dry through evaporation. After one year of drying, the
residuals are removed with a front-end loader and transported off -site for disposal. The remaining
lagoon is off-line and remains as a standby in case of emergencies.

In the future, to maintain annual turnover of the storage lagoons with increased solids production,
the lagoons will need to be enlarged. For lagoons 1 and 2, two additional feet will be excavated and
the length of the lagoons will be extended to the north for future growth. For lagoon 3, two feet will
be excavated.and the width and length will remain unchanged. The expansion and excavation of
the lagoons will not be completed in this project, but the future elevations will be used for the
proposed decant structure design and construction.

The proposed changes to the residuals handling system will require the existing residuals lines to
be cut, capped, and abandoned in place. The existing inlet and decant structures will be demolished
and replaced. The proposed hoseless track vacuum system will have new residuals headers
installed from the sedimentation basins to the residuals storage lagoons. In the proposed inlet
structure, the clarifier drain lines will discharge to the lagoons. The residuals and effluent drain
lines will be isolated from each other despite sharing the same inlet structure. The proposed
lagoon decant structures will include weirs and manual slide gates that can be adjusted throughout
the collection year. The decant structures for the three lagoons will tie together with manholes and
discharge by gravity to the wash water equalization basin.

2.8 CHEMICAL FEED AND STORAGE BUILDING
The following chemicals are used in the existing treatment processes: sodium hypochlorite,
aluminum sulfate, hydrofluosilicic acid, zinc orthophosphate, and sodium hydroxide. These
chemicals, with the exception of the sodium hypochlorite holding tanks, are stored in and pumped
out of the chemical storage building. Sodium hypochlorite is stored outside in an outdoor
containment structure with a canopy cover. The existing floor drains located in each chemical
storage room drain to the lagoons.
In this project, the existing storage tanks and chemical metering pumps will be removed and
replaced. A more detailed description of the Chemical Building modifications can be found in
section 3.0 - Chemical Feed Design Memorandum.

R.W. Neilson Water Treatment Plant
Solids Handling Plan
The Neilson Water Treatment Plant is a 48 MGD water treatment facility. Solids are
generated by manual sludge removal from sedimentation basins, backwashing filters, and
filter -to -waste after filter backwashes are completed. Solids produced from filter backwashes
and filter -to -waste is routed to a waste pump station and is then pumped to the head of the
water treatment process. Solids removed from the sedimentation basins are routed directly to
one of three residual lagoons.
Permits and Classifications:
1. The discharge from the residuals lagoons is authorized by NPDES Permit NCO086011.
The classification for the discharge is Grade 1 Physical/Chemical.
2. The distribution of the residuals removed from the lagoons is authorized by permit
WQ0031314. The residuals are classified as Class A.
Operation:
1. The system consists of a waste station with (3) Fairbanks Morse single stage pumps rated
at 6.48 MGD each, (2) Fairbanks Morse basin sludge pumps rated at 1.0 MGD each, (2)
lagoon pumps rated at 0.65 MGD each and (3) residuals lagoons (3 lagoons at —2.0 MG).
Each residuals lagoon consists of an oval earthen lagoon with clay bottom.
2. Routine inspections of equipment will be conducted Senior Utility Plant Supervisor to
ensure proper operation of equipment. Any equipment not functioning properly will be
reported through the water division's asset management program, MAXIMO, to the
appropriate support group for repair/replacement.
3. Backwash and filter -to -waste water from the plant process flows to the waste station and
then is pumped by the waste station pumps to raw water reservoirs at the head of the plant
treatment process.
4. All sedimentation basin and hopper blow downs are pumped by the basin sludge pumps
directly to one of three residuals lagoons.
The solids stream enters on one end of each lagoon and decant is pumped from the
opposite end by the lagoon pumps to the waste station where it is returned to the head of
the treatment process.
6. Residuals lagoons are rotated with one cleaned and ready for use, one in service and one
drying at all times.

7. Residuals are removed from the lagoons and hauled to the application site by a private
contractor.
Monitoring and Reporting Requirements:
1. Residuals generated by each source -generating facility must be analyzed to demonstrate
that they are non -hazardous based on the most current permit requirements (Attachment
A). Sampling will be conducted under supervision of the Senior Water Treatment Plant
Supervisor by WSFC Utilities current contractor as described below in compliance with
permit requirements.
2. Analysis will be performed by a NC Certified Laboratory.
3. Analyses made according to monitoring and reporting requirements must be certified for
the required parameter(s).

The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters (NELAP and non-NELAP) were performed in accordance with guidelines established by the USEPA
(including 40 CFR 136 Method Update Rule August 2017) and NELAC unless otherwise indicated. Any
parameter for which the laboratory is not officially NELAP accredited is indicated by a' —'symbol. These are not
included in the scope because NELAP accreditation is either not available or has not been applied for. Additional
certifications may be heldiare available for parameters, where NELAP accreditation is not required or applicable.
A full list of certifications is available upon request.
Certain parameters (chlorine, pH, dissolved oxygen, sulflte...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.

Dear Mr. Brent Collins:
Waypoint Analytical, LLC. received sample(s) on 9/12/2019 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method. Where the laboratory was not responsible for the sampling
stage (refer to the chain of custody) results apply to the sample as received.
The analytical data has been validated using standard quality control measures performed as required by the
analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters (NELAP and non-NELAP) were performed in accordance with guidelines established by the USEPA
(including 40 CFR 136 Method Update Rule August 2017) and NELAC unless otherwise indicated. Any
parameter for which the laboratory is not officially NELAP accredited is indicated by a '-'symbol. These are not
included in the scope because NELAP accreditation is either not available or has not been applied for. Additional
certifications may be held/are available for parameters, where NELAP accreditation is not required or applicable.
A full list of certifications is available upon request.
Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time.
Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as -
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to
the samples included in this report.
Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Danyale Love
Project Manager
Laboratory's liability in any claim relating to analyses performed shall be limited to, at laboratory's option, repeating the
analysis in question at laboratory's expense, or the refund of the charges paid for performance of said analysis.

Control: The pumps will be controlled manually from the plant control
system or locally at the finished water pumping station. A low
level sensor will be provided in each finished water storage
reservoir to stop the pumps on low water level. Pump status and
alarm conditions, pump discharge valve position, and finished
water storage reservoir levels will be indicated locally and
transmitted to the plant control system.

G. WASH WATER AND RESIDUALS HANDLING
1. Wash Water and Residuals Handling.
Currently, a common drainage system exists for sedimentation basin
overflow, for basin drainage and residuals drawdown, for filter backwash
and filter -to -waste drainage, and for storm water. These flow streams drain
to the wash water and residuals pumping station where they are pumped to
one of two residuals storage lagoons. This practice will be abandoned and
the clear water and residuals flow streams will be separated and treated.
Spent wash water and filter -to -waste will discharge by gravity to a new wash
water equalization basin. The collected water will be pumped from the
equalization basin to a new wash water clarifier. Wash water clarifier
effluent will discharge to the creek in accordance with the NPDES permit.
The wash water drainage system upstream of the equalization basin will be
designed to allow all four filters to be simultaneously wasted at the design
filtration rate prior to the addition of ozone, and three filters to be wasted at
I-18

the design filtration rate after the addition of ozone (filter hydraulic grade
line is reduced). This drainage capacity assumes a maximum headloss of 5
feet through a filter's media and underdrain during the wasting period. This
drainage capacity is provided for an emergency condition when water
quality dictates the basins be wasted until necessary treatment adjustments
are made. Because this is an emergency condition and not part of the normal
plant operation, flows in excess of the equalization basin pumping capacity
will overflow to the plant overflow drain.
Unthickened residuals from the sedimentation basins will discharge by
gravity through the viewing pit to the residuals pumping station. Residuals
from the wash water clarifier will also discharge by gravity to the residuals
pumping station. The combined residuals will be pumped to the residuals
storage lagoons. Decant/overflow from the residuals storage lagoons will
flow by gravity back to the wash water equalization basin.

R.A. Thomas Water Treatment Plant
Solids Handling Plan
The Thomas Water Treatment Plant is an 18.0 MGD water treatment facility. Solids are
generated by automatic sludge removal from sedimentation basins, backwashing filters, and
filter -to -waste after filter backwashes are completed. Solids produced from filter backwashes
and filter -to -waste is routed to an equalization basin (0.545 MG), is treated with polymer, and
then pumped to a clarifier. Solids settled in the clarifier flow to the plants waste station and
are then pumped to one of two residuals lagoons (1.76 MG each) using one of three 0.288
MGD pumps. One lagoon is kept in service while the second is dried and cleaned. Clarified
water from the clarifier is discharged to an unnamed tributary of Salem Creek through the
permitted NPDES discharge NC0079821.
Permits and Classifications:
1. The discharge from the clarifier is authorized by NPDES Permit NC0079821. The
classification for the discharge is Grade 1 Physical/Chemical.
2. The distribution of the residuals removed from the lagoons is authorized by permit
WQ0031314. The residuals are classified as Class A.
Operation:
1. The system consists of a 0.545 MG equalization basin (EQ basin), (4) equalization basin
discharge pumps rated at 1.0 MGD each, a residuals clarifier rated at maximum weir
loading rate of 7.24 gpm/ft, a residuals pump station with (3) residuals pumps rated at
0.29 MGD each for transferring residuals to (2) residuals lagoons rated at 1.76 MG each.
2. Routine inspections of equipment will be conducted the Senior Utility Plant Supervisor to
ensure proper operation of equipment. Any equipment not functioning properly are
reported through the water division's asset management program, MAXIMO, to the
appropriate support group for repair/replacement.
3. Backwash and filter -to -waste water from the plant process flow by gravity to the EQ basin
and are pumped by the EQ basin pumps to the wash water clarifier.
4. 38% Sodium bisulfite is fed atone of two locations (influent or effluent to clarifier) for
dechlorination of effluent being sent out discharge NCO079821.
5. All sedimentation basin residuals and residuals from the wash water clarifier flow to the
residuals pump station and are then pumped directly to one of the two residuals lagoons.
R.A. Thomas Water Treatment Plant
Solids Handling Plan -Permit #WQ031314
Revised 07/14/2020

6. Clarified water from the washwater clarifier is discharged to an unnamed tributary of
Salem Creek through the permitted NPDES discharge NC0079821.
7. Residuals are dried then removed from the lagoons and hauled to the application site by a
private contractor.
Monitoring and Reporting Requirements:
1. Residuals generated by each source -generating facility must be analyzed to demonstrate
that they are non -hazardous based on the most current permit requirements (Attachment
A). Sampling will be conducted under supervision of the Senior Water Treatment Plant
Supervisor by WSFC Utilities current contractor as described below in compliance with
permit requirements.
2. Analysis will be performed by a NC Certified Laboratory.
3. Analyses made according to monitoring and reporting requirements must be certified for
the required parameter(s).
4. Corrosivity, ignitability, reactivity, and a Toxicity Characteristics Procedure analysis are
required once each permit cycle. The TCLP analysis includes the following parameters

6. Data to verify pathogen reduction and vector attraction reduction of the residuals is
maintained on file for five years. The required data is specific to the stabilization process
utilized, and is also sufficient to demonstrate clear compliance with the Class A pathogen
requirements and restrictions noted in 15A NCAC 02T .1106 (a) and (b) and vector
attraction reduction requirements in 15A NCAC 02T .1107 (a).
7. Proper records are maintained tracking all residuals activities. These records include the
source, volume, analysis, and recipient of the residuals.
8. Three copies, per application event, of all required monitoring and reporting requirements
are submitted annually before March 1, to NC DEQ-DWQ.
Performance Standards:
1. The pollutant concentrations in any residuals that are land applied to any land application
site shall not exceed the following Ceiling and Monthly Average Concentrations (i.e.
