SUBJECT: NPDES Renewal for Permit # NC0023876 — South Burlington WWTP
Dear Ms. Thedford,
The City of Burlington, NC requests renewal of NPDES Permit # NC0023876. 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 19 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
City of Burlington

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
complete.

Sludge Management Plan
South Burlington Wastewater Treatment Plant, Permit No. NCO023876
The South Burlington Wastewater Treatment Plant has three methods of disposing of treated
wastewater residuals (biosolids). All of these methods satisfy the requirements of 40 CFR 503
regulations and the state regulations for the disposal of wastewater residuals.
The South Burlington WWTP generated approximately 15.3 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 secondary sludge. This mixture averaged 3.9 % solids during 2017.
The lime stabilization method involves the storage (approximately 1,771,300 gallons of storage
capacity) of Dissolved Air Flotation thickened secondary 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 586,500 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 also removed through composting which is accomplished on -site. The
composting facility houses a belt press which allows for the production of cake. The cake product is
used in composting or transported to land -fills or other approved composting facilities.
Approximately 702,000 gallons (2017) per year were processed through composting and the
production of the cake product.
The 2018 TCLP testing for the land application biosolids, and the secondary cake are attached to
this NPDES permit application,
