SUBJECT: NPDES Renewal for Permit # NCO023868 — East Burlington WWTP
Dear Ms. Thedford,
The City of Burlington, NC requests renewal of NPDES Permit # NCO023868. Enclosed are one original and
two copies of the NPDES form 2A.
The operational data required by permit renewal is taken from the period October, 2015 through September,
2018.
All toxicity data that was previously submitted has been summarized and is included in Section E of this
renewal package.
We also request changes to routine monitoring for the following parameters:
BOD5 — We request a reduction from 5 samples per week to 2 samples per week — We believe
that a review of the historic data for this parameter will demonstrate that this request is justifiable.
Conductivity — Discontinue conductivity reporting — The City of Burlington is a member of the
Upper Cape River Basin Association, which conducts routine in -stream conductivity analysis sampling
and reporting.
We also would like to take this opportunity to renew our objections to the limit on Total Residual Chlorine of 28
ug/L. We believe that compliance should be based on the 50 ug/L threshold that the Division recognizes and
that the requirement to report sub-50 ug/L should not be included in future permits.
Thank you for your consideration of this permit renewal. Please contact us if you have questions for us
regarding these comments.
Respectfully Submitted,
Robert C. Patterson, Jr., PE
Water Resources Director

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's oufalls: 1) POTWs with a design flow rate greater than or equal to 1.0 MGD; 2) POTWs with a pretreatment program (or those that are required
to have one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two
species), or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results
show no appreciable toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information
requested in question EA for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to

Introduction
The East Burlington Waste Water Treatment Facility uses a 12 million gallon per day (MGD) Activated
Sludge — Activated Carbon system with carbon regeneration completed in 1980. The plant was originally
constructed in 1961 as a 6 MGD trickling filter plant. In 1993 the treatment plant was upgraded to
include chemical and biological phosphorous removal. In 2013 the treatment plant was upgraded by
changing the 2 aeration basins to 4 with return pumping back to the beginning of the basins to the
anoxic zones for nutrient removal. The plant is situated on Stone Quarry Rd. and is off NC Highway 70
near the town of Haw River. The treated effluent is discharged into the Haw River.
Treatment Process & Operation
Treatment Process Summary:
The basic treatment process consists of the following elements and is explained in more detail later in
this section.
1. Pretreatment- includes a mechanical bar screen, coarse manual bar screen, and grit removal.
2. Raw waste water pumping — includes four (4) 250 hp and two (2) 125 hp pumps.
3. Equalization Vault with flow metering for in -line flow to the primary clarifiers and an automated
feed valve that sends the flow to the equalization basin to allow equalized flow pumping.
4. Chemical feed system that includes aluminum sulfate and sodium hydroxide (caustic)
5. Primary clarification
6. Aeration with NRCY system and anoxic zones.
7. Activated sludge, secondary clarification, and sludge recycling.
8. Biological Nutrient Removal (BNR) — including denitrification of the return sludge and anaerobic
phosphorus release.
9. Tertiary filtration — including backwash storage and pumping.
10. Chlorination & dechlorination, cascade -type post aeration, and non -potable water reuse
11. Primary sludge handling and disposal — including gravity thickening; lime stabilization; biosolids
storage and land application
12. Secondary sludge handling and disposal — including gravity thickening; high pressure wet air
oxidation for sludge destruction and odor control.

Raw sewage first passes through the screening removal channel and then the grit Detroiter chamber.
These facilities are designed to remove coarse Settleable solids, such as rags, paper and sand from the
waste stream. This process is the first step in wastewater treatment and helps protect pumps and other
equipment.
The raw wastewater (influent flow) is pumped to the primary clarifiers, although an automated bypass
to the equalization basin has been provided for flexibility to control the flow through the plant. The
equalization basin is mixed by 4 floating mixers and aerated by 1 floating mechanical aerator.
Subsequent flow to the plant is controlled by a series of 2 pumps with VFD's and 2 fixed -flow pumps.
This smoothing of the hydraulic load greatly enhances plant performance and reliability.
The raw wastewater flows to the primary clarifiers and is where settleable solids are removed. At this
stage, the settleable solids, called primary sludge, is withdrawn and thickened in gravity thickeners. The
thickened sludge is then pumped to the digester (mechanically mixed) that was converted from an
anaerobic digester. The sludge is stored there until it is lime -stabilized to meet 40 CFR 503C regulations.
Finally, the lime -stabilized sludge is applied to State -permitted farmland under an approved Land
Application program. The Biosolids are stored in the 3 digester holding tanks.
The primary clarifier effluent flows to anoxic/anaerobic (BPR) tanks for phosphorus release after which it
is treated in four aeration basins. An alternate flow scheme puts the primary clarifier effluent directly
into the aeration basins. These 4 basins each have 2 zones, the first zone is anoxic and the second is
aerobic and they contain activated sludge. The sludge floc characteristics under these conditions
provide both carbonaceous BOD removal and nitrification of ammonia nitrogen in the same tank. Next,
the activated sludge is settled out in four final clarifiers. A large portion of the settled sludge is
recirculated back to the anoxic/anaerobic (BPR) tanks from the return sludge pump station. The
remaining portion of the activated sludge is wasted (pumped) to the secondary sludge thickeners.
Excess sludge from the activated sludge system is wasted to two gravity sludge thickeners. Then the
thickened sludge is treated under high pressure (800 psig) and temperature (460*F) to completely
oxidize the sludge to an inert ash. The ash is dewatered in a plate frame press and disposed of at the
landfill as cover material.
The secondary effluent then flows through six deep -bed Dynasand filter cells. Each cell contains seven
filter modules. The filters function to remove additional suspended solids and BOD. The filter backwash
wastewater flows back to the head of the influent or it can be stored in the backwash storage basin and
pumped back to the aeration tanks for subsequent treatment, although generally the filter backwash
water goes back to the plant influent.
Disinfection of the East Burlington treatment plant effluent is accomplished through chlorination. Two
solution feed, vacuum type chlorinators are used to supply chlorine solution to the chlorine contact
chamber. The chlorine contact chamber is also the reservoir for the treatment plant's non -potable
reuse water. Finally, the chlorinated effluent is dechlorinated with sulfur dioxide (SO2) and receives post
aeration by cascading down a stair -step aerator. The final quantity of effluent is measured by an open
channel Parshall flume.

Eight (8) industries discharge to sewers leading to the East Burlington Wastewater Treatment Plant, six
(6) are considered significant industrial users (SIU), and two (2) are Categorical industrial users (CIU). All
eight (8) come under the City's pretreatment program.
Special thanks is extended to all people who have made the operation of the East Burlington
Wastewater Treatment Facility successful this past year. These individuals cannot be thanked enough
for their dedication efforts to ensure that the facility is staffed continuously, operated effectively and
maintained properly.
NOTE: The East Burlington WWTP has three (3) stationary emergency generators on site; the
third generator was added in 2008. The first is located at the raw sewage pump station and
provides power to the raw sewage pumps. The second is located in the Zimpro solids handling
building which provides power to equipment in the building, and the third is located next to Duke
Energy's substation which provides power to the rest of the plant. In addition, the flow
equalization basin pump station and the plant operations building have "quick connect" gear
installed to connect to a portable (trailer mounted) generator.

Sludge Management Plan
East Burlington Wastewater Treatment Plant, Permit No. NCO023868
The East Burlington Wastewater Treatment Plant has two methods of disposing of treated
wastewater residuals (biosolids). Both of these methods satisfy the requirements of 40 CFR 503
regulations and the state regulations for the disposal of wastewater residuals.
The East Burlington WWTP generates approximately 10.4 million gallons (2017) of class B lime
stabilized biosolids annually for land application under non -discharge permit number WQ0000520
issued by NCDENR to the city of Burlington NC. This product is a mixture of hydrated lime and
biosolids using primary sludge. This mixture averaged 4.4 % solids during 2017.
The lime stabilization method involves the storage (approximately 400,000 gallons of storage
capacity) of gravity thickened primary sludge. As space becomes available, this thickened sludge is
transferred to lime stabilization contact tanks for stabilization with hydrated lime to a pH 12 or >
for over 2 hours and a pH of 11.5 or > for the remainder of the 24 hour process. This sludge is then
stored (approximately 800,000 gallons of storage capacity) and maintained at a pH 11.5 or higher
until it can be applied to the permitted farm land. Application as a liquid sludge is by surface spray
or subsurface injection. The City has 2,995 acres permitted by NCDENR for the sludge
management program. The City contracts with a biosolids management company (EMA) to
perform the transportation and site application of the biosolids product. EMA also assists with the
program recordkeeping and reporting. Annual reports are submitted to the USPEA and to
NCDENR.
Secondary sludge is thickened in gravity thickeners and processed through a Zimpro® wet air
oxidation unit at high pressure (800 psi) and temperature (460°F). The liquid waste stream then
goes to the activated sludge process train. The "ash" or waste solids from the process are settled in a
clarifier and dewatered with a plate -frame press to about 65% solids. These residuals are hauled to
the landfill and are incorporated as cover material.
Approximately 6.3 million gallons (2017) per year are processed through the Zimpro® process. The
solids content of the sludge stream feeding Zimpro® unit averaged 4.0%.
Due to mechanical issue in the previous years with the Zimpro® process and the lengthy down time
that was experienced, it was decide to install a 4 channel Fournier Rotary press that could run ash or
cake. In January of 2018 the installation was completed. The startup and the Authorization to
Construct were completed in March of 2018. When running the ash, the press produces a 60% solid
and the secondary cake was 17%.
The 2018 TCLP testing for the land application biosolids, Zimpro® "ash", and the Fournier's
secondary cake are attached to this NPDES permit application,
