Subject: Issuance of NPDES Permit Modifications
Permits NCO023868 and NCO023876
East and South Burlington WWTPs
Alamance County
Consistent with the Director's October 1, 2009, letter of intent to modify NPDES permits affected by the
Jordan Reservoir Nutrient Management Strategy rules and Burlington's subsequent request for further
permit modification, and in consideration of public comments on the draft permits, the Division is
forwarding herewith the revised NPDES permit for the East and South Burlington WWTPs. This permit
modification is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and
the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency, dated October 15, 2007.
The Division received no comments during the public review period. The enclosed permits include the
following changes as proposed:
• Total Phosphorus (TP) Limits. Phosphorus limits have been removed from Condition A.(1.) of each
permit. A new Condition A.(2.) describes the combined TP limit for the two facilities and how it
will be administered. Other nutrient -related conditions of the permit have been modified as
necessary. Each facility will continue to monitor and report its nutrient discharges individually, and
we propose that the City report the combined load once each year, with the December monitoring
report for one plant. Phosphorus limits in the Jordan Lake watershed became effective January 1,
2010, according to the wastewater rule.
• Standard Permit Conditions. Most of the comments received from the Jordan Lake dischargers
during the public review pertained to changes in the standard conditions, Parts I1,111, and IV of the
permits. The permittees noted a small number of minor errors, but most comments had to do with
changes in Part IV, where language was revised in anticipation of changes in the state pretreatment
rules. The Division has corrected the minor errors and reversed all changes from Part IV that are
not supported by existing state or federal rules.

Issuance of NPDES Permit Modifications
November 5, 2010
• Treatment Process Description. The reference to Powdered Activated Carbon Treatment on the
Supplement to Cover Page for the East Plant (NC0023868) has been modified to note that the
process is no longer in use. So long as the equipment remains in place and operative, it is not
appropriate to remove it from the process description altogether.
• pH Monitoring. Condition A.(1.) of the East Plant has been corrected to specify daily (rather than
weekly) pH monitoring to satisfy the wastewater monitoring rule, T15A NCAC 02B .0508.
• Nitrogen Optimization. The previous draft permit included a new condition pertaining to nitrogen
optimization requirements from the wastewater rule. That compliance -date has passed, and the
proposed condition has been deleted from the permit.
• Nutrient Re -opener. The nutrient monitoring re -opener from the previous permit pertained to
monitoring in preparation for the Jordan Lake study. It is no longer necessary and has been deleted
from the permit.
• Total Residual Chlorine Footnote. A footnote has been added to Condition A.(1.) indicating that
the Division considers the compliance level for TRC to be 50 ug/L. All lab values must still be
reported but, for compliance purposes, values below 50 ug/L meet the facility's TRC limit.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty
(30) days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the office of
Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a
demand is made, this permit shall be final and binding.
This permit is not transferable except after notice to the Division of Water Quality. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Quality, the
Division of Land Resources, the Coastal Area Management Act, or any other federal or local
goverrunental permit.
If you have any questions concerning this permit, please contact Mike Templeton at (919) 807-6402 or at

A.(4.) CHRONIC TOXICITY PASS/FAIL, PERMIT LIMIT
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 86%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
January, April, July and October. Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below
the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the
two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
specified in the "-North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were.performed, using the parameter
code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWQ Form AT-
3 (original) is to be sent to the following address:
NCDENR/ DWQ/ Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved
designate signature. Total residual chlorine of the effluent toxicity sample must be measured and
reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the
report with the notation of "No Flow" in the comment area of the form. The report shall be submitted
to the Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month. Should any test data from this monitoring
requirement or tests performed by the North Carolina Division of Water Quality indicate potential
impacts to the receiving stream, this permit may be re -opened and modified to include alternate
monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later
than the last day of the month following the month of the initial monitoring.

of the North Carolina Administrative Code, specifically,15A NCAC 02B.0270, and Part II,
Sections B-12 and B-13 of this permit, the Division of Water Quality (Division) may reopen the
permits listed above and establish more stringent nutrient limits upon finding that such limits are
necessary to prevent the discharges from causing localized water -quality impacts in the receiving
streams.
(e.) The Permittee may request that its permits be modified to rescind these combined limits and
establish individual mass discharge limits for each facility. The Division may, after written
notification to the Permittee, rescind these combined limits and establish individual mass
discharge limits for each facility if it determines that the combined limits do not support the
objectives of the Jordan Lake Nutrient Management Strategy. The Division shall provide for
public review of the proposed permit modifications and include in the permit an appropriate
schedule of compliance for the proposed nutrient limits.

Fact Sheet - NPDES Permit
Jordan Lake NPDES Dischargers
4 NPDES Permits
PROPOSED PERMIT ACTION
The Division proposed to modify four (4) NPDES permits for municipal wastewater treatment
facilities in the Jordan Lake watershed of the Cape Fear River Basin. The purpose of the
modifications is to set Total Phosphorus discharge limits in accordance with the Jordan Lake
Nutrient Management Strategy: Wastewater Discharge Requirements, T15A NCAC 02B .0270.
The Division first proposed related modifications for these permits in November 2009 and then
modified the draft permits in response to comments from the Permittees.

JORDAN LAKE NUTRIENT MANAGEMENT STRATEGY
The Jordan Lake Nutrient Management Strategy is a comprehensive set of rules and Session
Law that became effective August 11, 2009. The Strategy aims to restore and maintain water
quality, protect the lake's classified uses, and maintain or enhance protections currently
implemented by local governments in existing water supply watersheds. The Strategy calls for
improvements in stormwater management (existing and new development), agricultural
practices, fertilizer application management, riparian buffers protection, and wastewater
treatment.
The Strategy establishes nitrogen and phosphorus allocations for all existing wastewater
dischargers that treat nutrient -bearing wastes. For point sources, it specifies that facilities with a
permitted flow of 0.1 MGD or greater must meet nutrient limits based on these allocations. The
limits for both nitrogen and phosphorus are to be given as annual mass limits. The phosphorus
limits become effective in CY2010, the nitrogen limits in CY2016.
The figure below shows the watershed and the three subwatersheds. The strategy sets nutrient
reduction targets for each subwatershed.
PROPOSED MODIFICATIONS
The Division proposes to incorporate the new phosphorus limits and related conditions into the
affected permits. It intends to add nitrogen limits during the 2011 permit renewals.
The proposed permit modifications go beyond adding the phosphorus limits, which were first
proposed for the Greensboro and Burlington facilities in November 2009. The revised draft
permits propose to apply combined TP limits for each City's wastewater facilities. In each case,
the combined limit equals the sum of the City's individual allocations. In order to account for
differences in transport losses in transit to Jordan Lake, the combined limits are expressed as
delivered (as opposed to discharge) loads. Other nutrient -related conditions in the permits have
been modified to reflect this arrangement.
The modifications include minor changes as well. Out-of-date Special Conditions (for example,
for requirements now completed) have been deleted.
PUBLIC COMMENTS
Greensboro noted one. additional correction in the standard permit conditions, which was
corrected.
10-0,/:l 1MMUM4]-01I
The four permits are being issued as proposed, except for the one correction in the standard
conditions.

Dear Mr. Owen:
Governor Bev Perdue recently signed legislation to complete passage of rules for the Jordan Lake
Nutrient Management Strategy. The Strategy includes a Wastewater Discharge rule (T15A NCAC 02B
.0270) that applies to your wastewater treatment facilities. Pursuant to Sub -Item (6)(d) of that rule, I am
writing to notify you of (1) the nutrient allocations assigned to your facilities and (2) the Division of
Water Quality's intent to modify the subject NPDES permits to include nutrient limits as provided in
the rule. I also wish to remind you of other provisions of the rule that require your prompt attention.
This letter addresses only certain provisions of the Jordan Lake Wastewater Discharge rule. I encourage
you to familiarize yourself with the remainder of the rule.
Nutrient Allocations. The Wastewater Discharge rule establishes the maximum loads of nitrogen and
phosphorus that can be released from wastewater treatment facilities into the Jordan Lake watershed.
The rule specifies that these wasteload allocations are to be divided among the existing facilities in
proportion to their 2001 permitted flows (with certain exceptions).
Your facilities have been assigned nitrogen and phosphorus allocations. The allocations are expressed
as annual mass loadings delivered to the lake. Due to foreseeable losses between the discharge point
and the lake, they are also expressed as the equivalent discharge loads at the point of discharge. The
delivered and the corresponding discharge allocations assigned to the City of Burlington are as follows:

Intent to Modify Permit. The new rule specifies that facilities with permitted flows at or above 0.1
MGD, including yours, will be subject to effluent limits for nitrogen and phosphorus. The effluent
limits will equal the facility's discharge allocations. The new phosphorus limits become effective
beginning with calendar year 2010. Nitrogen limits become effective beginning with calendar year
2016.
It is the Divisions intent to modify the affected permits by the end of 2009 to include the new
phosphorus limits. We will draft permit modifications for the affected facilities in the coming weeks.
As with any such permit action, the proposed modifications will be subject to public review, and we
will provide you with a copy of the draft permit at that time.
The Division will add nitrogen limits during the 2011 permit renewals, with a compliance date of 2016.
Process Optimization. The rule specifies that no later than six months after its effective date, each
discharger with a permitted flow greater than or equal to 0.5 MGD must "evaluate its treatment
facilities and operations and identify further opportunities to improve and minimize nitrogen
reduction in the existing facilities...; and submit a report to the Division documenting its findings,
proposing optimization measures, and describing expected results."
Please provide three copies of your reports to the Division at the following address no later than
February 11, 2010:

Each discharger must implement the proposed measures no later than six months after the Division
accepts the report and continue until such time as the facility is upgraded for nitrogen removal.
Affected dischargers must also submit annual progress report to the Division for a period of five years.
If you have any questions regarding these requirements, please contact Mike Templeton at (919) 807-
6402 or at mike.templeton@ncdenr.gov.
