Dear Mr. Jordan:
Division of Water Quality (Division) personnel have reviewed and approved your application for
renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit.
It 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.
This final permit contains the following changes from the previously -issued permit:
• The effluent table for the 8.0 MGD flow was eliminated.
• Obsolete conditions including those concerning historical permit limits and the development of
an effluent mixing model were eliminated.
• The priority pollutant scan requirement was changed from annual to three times during the current
permit term, consistent with your request and with Division guidance for major municipal
wastewater treatment facilities. Please note that this testing requires a low-level sampling method
for mercury (EPA Method 1631E). Your request for monitoring frequency reductions for other
parameters has been deferred to an ongoing larger evaluation in response to a request by the NC
Water Quality Association.

• Ammonia limits were added to the 10 MGD flow rate, in accordance with Division guidelines for
major municipal wastewater facilities. Effluent sampling data over the past three years indicates
that these limits are consistently met by a considerable margin.
• The PNA classification was added to the stream description on the supplement to permit cover
sheet and on the attached map.
• In accordance with the new PNA classification, and in lieu of modifying TSS limits, a special
condition was added to ensure that the tertiary filters would not be taken off line during normal
operations.
• The description of treatment units in the supplement to permit cover sheet was updated.
In response to your comment that the facility has no chlorine disinfection, total residual chlorine
limits were eliminated from the final permit.
• Due to the lack of reasonable potential to cause exceedances of water quality standards,
monitoring requirements for copper, cyanide, silver, and zinc were eliminated.
• For the expanded 16.0 MGD flow, the quarterly acute toxicity test requirement was changed to a
quarterly chronic toxicity test. This is because the facility uses a dilution factor to determine an
instream waste concentration (IWC). The new chronic tests will be required for the same calendar
months as had been required for the acute toxicity test, namely February, May, August, and
November.
Please note that the lower Cape Fear River is listed as an impaired waterbody on the North Carolina
303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and
instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits
and stream impairment can be attributed to your facility, then mitigative measures may be required.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing upon written request within thirty (30) days
after receiving this letter. Your request must take the formof a written petition conforming to Chapter
150B of the North Carolina General Statutes, and must be filed with the Office of Administrative
Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such demand is
made, this permit remains final and binding.
This permit is not transferable except after notifying the Division of Water Quality. The Division may
modify and reissue or revoke this permit. Please note that this permit does not affect your legal
obligation to obtain other permits required by the Division of Water Quality, the Division of Land
Resources, the Division of Coastal Management, or other federal or local agencies.

Permit NC0023965
A (3) ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (10.0 MGD)
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the
North Carolina Procedure Document entitled "Pass/Fail Methodology for Determining Acute Toxicity In
a Single Effluent Concentration" (Revised July, 1992 or subsequent versions). The monitoring shall be
performed as a Ceriodaphnia dubia 24-hour static test. The effluent concentration at which there may
be at no time significant acute mortality is 90% (defined as treatment two in the procedure document).
Effluent samples for self -monitoring purposes must be obtained during representative effluent
discharge below all waste treatment. The tests will be performed during the months of February, May,
August and November.
All toxicity testing results required as part of this permit condition will be entered on the effluent
discharge monitoring form (MR-1) for the month in which it was performed, using the parameter code
TGE3B. Additionally, DWQ Form AT-2 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. 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 any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then
monthly monitoring will begin immediately until such time that a single test is passed. Upon passing,
this monthly test requirement will revert to quarterly in the months specified above.
Should any test data from either these monitoring requirements 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.
If the permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT
forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival 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.

Permit NC0023965
A (4) CHRONIC TOXICITY PERMIT LIMIT (16.0 MGD)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 4.8%.
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
February, May, August and November. 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:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
621 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.

Permit NC0023965
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.
A (5) STIPULATION OF PARALLEL FORCE MAINS
By Authorization to Construct (ATC) for expansion to 16 MGD, the Division of Water Quality approved
a new effluent force main and outfall (outfall 002 with diffuser) approximately parallel to the existing
effluent force main. The permittee shall sample final treated effluent upstream of any flow split to
effluent pump stations or discharge force mains. The Division acknowledges separate outfalls,
however due to their proximity and the single sampling regime conducted prior to splitting, the Division
shall designate and regulate this discharge as a single outfall (outfall 001). The Division may reopen
this permit to designate separate outfalls.
A (6) FILTER BYPASS PROHIBITION IN A PRIMARY NURSERY AREA (PNA)
This outfall discharges to a segment of the Cape Fear River classified as a primary nursery area
(PNA). Therefore, at no time shall the effluent bypass the tertiary filters. However, the number of
filters which are on-line at any given time may be adjusted for routine maintenance or to be consistent
with process and equipment design loadings and required performance. If the filter system is taken out
of service for any reason, the permittee must notify the Division's Wilmington Regional Office, Surface
Water Protection Section within 24 hours. This condition is to minimize TSS concentrations in the
lower Cape Fear River.

Permit NC0023965 •
A (7) EFFLUENT POLLUTANT SCAN
The permittee shall perform a total of three (3) Effluent Pollutant Scans for all parameters listed below. One scan
must be performed in each of the following years: 2013, 2014, and 2015. Analytical methods shall be in
accordance with 40 CFR Part 136 and shall be sufficiently sensitive to determine whether parameters are present
in concentrations greater than applicable standards and criteria. Samples should be collected with one quarterly
toxicity test each year, and must represent seasonal variation [i.e., do not sample in the same quarter every year].
Unless otherwise indicatedmetals shall be analyzed as "total recoverable."

• The James A. Loughlin WWTP (Northside) is a publicly owned treatment works utilizing
a conventional treatment system to treat domestic and industrial wastewater. The
treatment system utilizes mechanical/manual bar screens, grit removal, primary
clarifiers, aeration basins, secondary clarifiers, trickling filters, UV disinfection, anaerobic
digesters, and sludge dewatering facilities.
• The previous permit issued on March 7, 2008 included phased limits of 8, 10, and 16
MGD. In September 2004 the facility received an ATC for an upgrade to 16 MGD. An
engineer's certification for the completion of the upgrade to 16 MGD has not been
received.
• During the past permit renewal period, construction was completed on the expansion to
10 MGD. An authorization to operate (023965A02) at this flow was issued by the
Division on June 30, 2008.
• On August 26, 2008, this permit transferred ownership from the City of Wilmington to the
newly -created Cape Fear Public Utility Authority (CFPUA). The CFPUA was created
from a merger of the City of Wilmington and New Hanover County.
• Northside services 25,078 accounts. For the past three years (2009-2011), yearly
average flows varied within the range of 7.38 to 7.80 MGD as reported in monthly
discharge monitoring reports (DMRs).
• A second diffuser (outfall 002) has been constructed. Dual parallel effluent force mains
are planned between the WWTP and the two outfalls. Outfall 002 is located 400 feet
downstream of the first outfall, and has been in use since August 15, 2008. As per the
Fact Sheet
Renewal -- NPDES Permit NC0023965
Page 1

recommendation of the Wilmington Regional Office, and the Division's agreement with
CFPUA, the facility is regulated as having only one outfall (outfall 001). This permit
renewal proposes to continue that practice.
• The permittee is a member of the Cape Fear Monitoring Coalition, and all its instream
monitoring is conditionally waived for the duration of its membership in the coalition.
• Northside has a full-scale pretreatment program with four significant industrial users.
The largest is Coty, US LLC, which manufactures cosmetics. Its total influent flow to the
VVVVfP averages 37,000 GPD.
• As a member of the NC Water Quality Association, the permittee requested a reduction
in monitoring frequencies for criteria pollutants; a reduction in toxicity monitoring from
quarterly to annually, and a reduction in priority pollutant analyses from annually to three
times per permit renewal period. The PPA frequency will be reduced as requested, but
no other monitoring reductions will be made. Existing monitoring frequencies will be
kept for compliant municipalities such as the Northside WWTP until a new policy can be
developed. This is to ensure consistency when dealing with future requests for
monitoring frequency reductions.
• The permittee also requested that toxicity monitoring be required annually instead of
quarterly. The Division also denied this request. Toxicity is a fundamental part of water
quality, and quarterly testing is a cornerstone of the Division's program.
• Modeling was performed by the permittee to satisfy an existing permit condition requiring
a CORMIX or equivalent model to provide end -of -pipe dilution estimates for a permitted
flow of 16 MGD, for both discharge line diffusers. Modeling results were received by the
Division on November 7, 2008. After review, a dilution factor of 20.7 was accepted for
outfall 001 and 22.7 for outfall 002. The more conservative 20.7 factor was used
throughout this permit review, resulting in an in -stream waste concentration of 4.83%.
• Monitoring coalition summary data for instream monitoring 2006-2010 was reviewed for
dissolved oxygen (DO), pH, chlorophyll -a, TSS, and fecal coliform. No problems were
noted.
• Cape Fear River segment 18-(71)a from Toomers Creek to Snows Cut (5,616.7 acres) is
impaired for aquatic life due to low DO The DO standard for SC waters is 5 mg/L.
Although there will be not be a TMDL in the near future to address DO in the Lower
Cape Fear River and estuary, a site -specific standard may eventually be developed.
• Following the Cape Fear Basin permitting strategy, Northside will continue to monitor
nutrients at the frequencies set in the existing permit, which is consistent with those in
the 2B .0508 rules.
REASONABLE POTENTIAL ANALYSIS
To establish a list of pollutants of concern (POCs), the Division examined the permit
application, the submitted priority pollutant analyses, and three years of discharge
monitoring reports (January 2009 through December 2011). According to the Pretreatment
Unit, all LTMP data are included in the DMRs. Based on results of the effluent dilution
analysis submitted in September 2008, a mixing zone dilution factor of 20.7:1 was utilized
during the reasonable potential analysis (RPA) for both 10 MGD and 16 MGD. This dilution
represents an instream waste concentration (IWC) of 4.83% at 16 MGD.
Pollutants of concern included in the RPA were arsenic, copper, cyanide, cadmium,
chromium, lead, mercury, molybdenum, nickel, silver, selenium, phenol, and zinc. There
was no reasonable potential for any of these parameters, and none of the maximum

• In accordance with the new PNA classification, and in lieu of modifying TSS limits, a
special condition was added to ensure that the filters would not be taken off line during
normal operations.
• In response to comments from the Planning Section and the Environmental Sciences
Section, minor changes were made to the map, including the separate labeling of each
outfall. Additionally, more accurate descriptions of the instream monitoring locations
were made in the first footnote to Table A (1) and Table A (2).
• The description of treatment facilities on the supplement page was updated according to
comments made by the permittee and the Wilmington Regional Office.
• In response to a comment made by the permittee regarding the draft permit, total
residual chlorine limits were eliminated from the final permit. The facility has no chlorine
disinfection facilities. Chlorine disinfection was also taken out of the facilities description.
• Due to the lack of reasonable potential to cause exceedances of water quality standards,
monitoring requirements for copper, cyanide, silver, and zinc were eliminated.
• For the 16.0 MGD flow, the quarterly acute toxicity test requirement was changed to a
quarterly chronic toxicity test. This is because the facility now uses a dilution factor to
determine an IWC. The new chronic tests will be required for the same calendar months
as had been required for the acute toxicity test, namely February, May, August, and
November.

predicted concentrations were above 50% of the limit. As a result, the existing monitoring
requirements for copper, cyanide, silver, and zinc will be removed from the permit.
During this review period, all monitoring for mercury was done using method 245-1, showing
no hits. The renewed permit will specify low-level Method 1631E monitoring for the next
PPAs, in order to gain meaningful sampling data for this parameter.
WHOLE EFFLUENT TOXICITY (WET) TEST
Previously, the facility had been monitoring acute toxicity, pass/fail, at 90% effluent
concentration quarterly. After discussion with the Division's Aquatic Toxicology Unit, this will
be changed to a quarterly chronic toxicity test at 4.83% effluent concentration. The reason
is that the facility now uses a dilution factor to determine an IWC. The new chronic tests will
be required for the same calendar months as had been required for the acute toxicity test,
namely February, May, August, and November.
COMPLIANCE REVIEW
• A staff report was received from the Wilmington Regional Office (WiRO) on July 20,
2011. It recommended adding the PNA-designation to the permit, and imposing the
corresponding limits for TSS. As per Division guidelines, the PNA classification will be
added; however, TSS limits will remain as is the existing permit. Since the facility has
already designed for the 16.0 MGD expansion and received an authorization to
construct, it was not practical to use the lower TSS limits (10 mg/L monthly average). In
lieu of this, a special condition will be added which prohibits the bypassing of the existing
tertiary filters.
• The permittee has passed all WET tests from February 2003 to the present.
• DMRs from January 2007 until the present were reviewed for effluent limit violations.
Other than a minor PH exceedance in 2008, there were none. Even with such an
excellent compliance record, the facility's performance is expected to improve once the
ongoing construction is completed and new treatment facilities are operational.
SUMMARY OF PROPOSED CHANGES
• The effluent table for the 8.0 MGD flow was eliminated.
• Obsolete conditions including those concerning historical permit limits and the
development of an effluent mixing model were eliminated.
• The priority pollutant scan frequency was reduced to three events per permit cycle in
accordance with EPA permit renewal application requirements.
• An ammonia limit was added to the 10 MGD flow rate, in accordance with Division
guidelines for major municipal wastewater facilities.
• The receiving stream classification was changed to SC-PNA to reflect its status as a
primary nursery area.

Nora:
Condition A (4) of the permit explains it:
By Authorization to Construct (ATC) for expansion to 16 MGD, the Division of Water Quality approved a new
effluent force main and outfall (with diffuser) approximately parallel to the existing effluent force main. The
permittee shall sample final treated effluent upstream of any flow split to effluent pump stations or discharge
force mains. The Division acknowledges separate outfalls, however due to their proximity and the single
sampling regime conducted prior to splitting, the Division shall designate and regulate this discharge as a
single outfall (outfall 001). The Division may reopen this permit to designate separate outfalls.
So, BIMS is correct; the location on the map (lat/long) is correct; Smith's Creek is nowhere in the picture
nowadays; and there is only one outfall for tracking purposes.

Subject: Outfall issue with Cape Fear Northside (NC0023965) permit -
Hi Gil,
There is a problem with the information regarding the outfall (001 & 002) locations for the Cape Fear Public Utility
Authority's Northside WWTP (NC0023965).
BIMS indicates that there is one outfall (001) and it is located on the Cape Fear River.
The permit that is up for renewal indicates that there are 2 outfalls (001 & 002). A map included indicates that these
outfalls are very close together and located at the confluence of the Cape Fear River and the Northeast Cape Fear River.
I was looking through the 1996 permit file for the Cape Fear Public Utility Authority's Northside WWTP (NC0023965) and
found in a memo indicating that outfall 001 is located in Smith Creek (@ latitude 34° 15' 47" Longitude 77° 55' 19") and
outfall 002 is located in the Cape Fear River (@ latitude 34° 14' 29" Longitude 77° 57' 11").
So.l'm not sure if the outfall 001 is different now from the 1996 outfall 001? If it is not, then there is a concern that the
limits and volume discharged to this small stream may have a detrimental effect. Can you clarify the exact locations of
the outfalls? BIMS outfall information needs to be updated as well.
Issues I see:
1. BIMS is missing an outfall.
2. Location of these outfall 001 is possibly wrong.
3. If this treatment plant is utilizing an outfall into Smith Creek, I believe the limits are not protective of the small
tributary.

4. Is this WWTP still utilizing two outfall?
Could you please let us know what you find. I still have the 1996 and 2004 files pulled from central files if you
should need them.
Thank you for your help in clarifying this situation.

To: Gil Vinzani, NPDES
From: Steve Kroeger, EU Supervisor
Jeff Manning, BP Supervisor
Re: Draft NPDES Permit Renewal — CFPUA Northside WVVTP (NC0023965)
Thank you for the opportunity to review the draft NPDES permit (NC0023965) for the James A.
Loughlin (Northside) VVWTP. Staff from the Ecosystems Unit and the Basinwide Planning Unit
reviewed the permit. Our comments, are below.
• Upstream sampling point U1 is an AMS station (B9740000). The station descripti n
indicates that the road identified as US 421 in the permit, is actually NC 133. US 1
does not cross the NE Cape Fear River.
• .On the map in the permit, please clearly identify Outfall 001 and Outfall 002.
• Neither "Muddy Point" nor "Port Authority" are comprehensive descriptions of sampling
locations. These landmarks are not clearly identified on the map within the permit, or on
other maps (e.g. Delorme NC Gazetteer) we looked at. Sampling at these locations was
originally intended to be conducted mid -channel, and this is not clear in the descriptions.
o Port Authority — this appears to be the same location as AMS station B980! 0
This station must be accessed by boat. Therefore, it is suggested that you
this location as Channel Marker 61 on the Cape Fear River.
o . Muddy Point — this location is extremely difficult to find. It is suggested that you
include lat/long and state that the site is on the Cape Fear River.
• Please use consistent language when referring to the exemption of in -stream monitoring
requirements for coalition members. The following wording is suggested:
As a member of the Lower Cape Fear River Program (LCFRP), instream monitoring
requirements are provisionally waived. If your membership in the LCFRP is terminated,
or if the LCFRP ceases to function, the Division shall be notified immediately and t
instream monitoring requirements in this permit become effective. The Division ma
then reopen this permit to establish any additional instream monitoring requiremen
deemed necessary to adequately characterize the effects of discharges on water quality
in the receiving stream.
• If a clause stating the permit may be reopened upon cessation of membership in the
LCFRP cannot be included in the permit, we would like to discuss the inclusion of n
additional instream requirements in the permit, including, but not limited to nutrients and
enterococci, if membership in the LCFRP is discontinued for any reason.
• A DO daily average requirement of > 6 mg/L should be included in the 10 MGD effluent limits. MAX -
This facility discharges into a section of the CFR that is impaired for DO (2010 303(d) list).

Similar to CFPUA Southside, I do not have any recent data for the CFPUA Northside plant in spreadsheet form; however,
all data is included on the DMRs. Also, the sampling frequency in the monitoring plan is the same for both plants (that
the POTW will perform quarterly sampling); however, they've performed monthly sampling from February -November
(the most recent DMR on file) at the Northside plant as well. The frequency was quarterly prior to February 2011.
Thanks,

23.3 Magnitude for Whole Effluent Tox/clty
Criteria for toxicity in current State standards range from the
narrative prohibition (e.g., no discharge of toxic chemicals in
'oxic amounts) to detailed requirements that specify the test
,pecies and the allowable toxicity level. At present, there are no
national criteria developed under CWA Section 304(a) for whole
effluent toxicity. Acute and chronic toxicity units (TUs) are a
mechanism for quantifying instream toxicity using the whole
effluent approach. The procedure to implement the narrative
criteria using a whole effluent approach should specify the testing
procedure, the duration of the tests (acute or chronic), the test
species, and the frequency of testing required.
EPA's recommended magnitudes for whole effluent toxicity are as
follows (again, two expressions of allowable magnitude are used):
a CMC to protect against acute (short-term) effects and a CCC to
protect against chronic (long-term) effects. For acute protec-
tion, the CMC should be set at 0.3 acute toxic unit (TUa) to the
most sensitive of at least three test species.
The selection of test species for testing the effluent is not critical
provided species from ecologically diverse taxa are used (e.g., a
fish, an invertebrate, and a plant). The factor of 0.3 is used to
adjust the typical LCS0 endpoint of an acute toxicity test (50
percent mortality) to an LC1 value (virtually no mortality). Spe-
cifically, a factor of 0.3 was found to include 91 percent of
observed LC1 to LC50 ratios in 496 effluent toxicity tests as illus-
trated in Figure 2-2-T is figure presents effluent toxicity data
from many years oftoxicity testing of both industrial and munici-
pal effluents by the Environmental Services Division, U.S. EPA

For chronic protection, the CCC should be set at 1.0 chronic
toxic unit (TUc) to the most sensitive of at least three test
species. The selection of test organisms is as described above. A
1.0 TUc is applied at the edge of the mixing zone to prevent any
chronic toxicity in the receiving water outside the mixing zone.
2.3.4 Duration for Single Chemicals and Whole Effluent Toxicity
The quality of an ambient water typically vanes in response to
variations of effluent quality, stream flow, and other factors. Or-
ganisms in the receiving water are not experiencing constant,
steady exposure but rather are experiencing fluctuating exposures,
including periods of high concentrations, which may have adverse
effects. Thus, EPA's criteria indicate a time period over which
exposure is to be averaged, as well as a maximum concentration,
thereby limiting the duration of exposure to elevated concentra-
tions.
For acute criteria, EPA recommends an averaging period of 1
hour. That is, to protect against acute effects, the 1-hour average
exposure should not exceed the CMC. The 1-hour acute averag-
ing period was derived primarily from data on response time for
toxicity to ammonia, a fast -acting toxicant. The 1-hour averaging
period is expected to be fully protective for the fastest -acting
toxicants, and even more protective for slower -acting toxicants.
Scientifically justifiable altemative (site -specific) averaging periods
can be derived from (1) data relating toxic response to exposure
time, if coupled with considerations of delayed mortality (mortality
occurring after exposure has ended), or (2) models of toxicant
uptake and action, such as presented by Erickson [5] and Mancini
et al. [4].
In practice, 1-day periods are the shortest periods for which WLA
modelers and enforcement personnel have adequate data. Attain-
ment of the duration criterion can be ensured by paying particular
attention to short-term effluent variability and requiring measures
to control variability (e.g., installation of equalization basins) when
needed.
For chronic criteria, EPA recommends an averaging period of 4
days. That is, the 4-day average exposure should not exceed the
CCC. Different chronic averaging periods could be derived, de-
pending on the nature of the pollutant and the toxic endpoint of
concem (e.g., the rate of uptake and accumulation, and the mode
of action).
The toxicity tests used to establish the national criteria are con-
ducted using steady exposure to toxicants usually for at least 28
days. The test concentrations do not fluctuate as much as typically
occurs instream. As the period of averaging increases, so too does
the period of time the exposure concentrations can be above the
criterion concentration without exceeding the average. The sig-
nificant consideration involved in setting duration criteria is how
long the exposure concentration can be above the criterion con-
centration without unacceptably affecting the endpoint of the test
(e.g., survival, growth, or reproduction). EPA selected the 4-day
averaging period based on the shortest duration in which chronic
effects are sometimes observed for certain species and toxicants,
and thus should be fully protective even for the fastest -acting
toxicants.

NPDES Permit Renewal Staff Report
To: Gil Vinzani, NPDES Complex Permitting Unit
From: Dean Hunkele, Senior Environmental Specialist — Wilmington
Facility: Wilmington Northside (NC0023965)
No inspection conducted for this report.
Facility address & lat/longs and outfall Iat/longs have been updated in BIMS.
Specific Permit Comments:
1. The permit should be corrected to reflect the appropriate surface water classification of
PNA HQW. The permit needs to impose TSS limitations of 10 mg/L (daily maximum) if
tertiary treatment or similar is provided at the facility. This facility has filters and has
averaged less than 2.0 mg/L for the past year and less than 4.0 mg/L since 8-1-2008.
2. The permit should have up to a 12-month compliance schedule to begin operating at the
16 MGD level. We granted them an A-to-O for 10 MGD on 3-4-2008 to avoid a possible
sewer moratorium and those limits became effective 8-1-2008.
Only thing lacking is the parallel discharge line & diffuser. Supposedly the project is
back on track following the lack of an easement being acquired for new outfall line prior
to design/approval.
3. Our office cannot support the requested reduction in monitoring especially in light of
both items above. Perhaps 3x/week on standard parameters, PPA should remain at
annual for this facility due to its industrial users. It should be designated as only having
a single outfall as all effluent passes the same location after all treatment.

Re: Renewal Application - NPDES Permit NC0023965
James A. Loughlin Wastewater Treatment Plant (WWTP)
Cape Fear Public Utility Authority (CFPUA)
New Hanover County, North Carolina
Dear Mrs. Sprinkle,
National Pollutant Discharge Elimination System (NPDES) permit NC0023965 for the
Cape Fear Public Utility Authority's James A. Loughlin WWTP expires December 31,
2011 and its renewal application is due at the Department of Water Quality no later
than July 4, 2011. In fulfillment of this deadline, the necessary NPDES renewal
application accompanies. It consists of the following components:
1. NPDES Form 2A Basic Application
2. NPDES Form 2A Supplemental Application, Parts D, E, and F
3. James A. Loughlin WWTP Process Flow Diagrams with Narrative
4. James A. Loughlin WWTP Major Equipment List
5. Topographic Map
6. Sludge Management Plan
Changes implemented at this facility since issuance of the last permit include the
following:
1. The expansion/upgrade project to expand hydraulic capacity from 8 MGD to
16 MGD and to upgrade level of treatment provided from secondary to
advanced.
2. Increase in NPDES capacity from 8 MGD to 10 MGD; further increase in
NPDES capacity from 10 MGD to 16 MGD awaits installation of additional
facilities.
3. Phased installation of additional effluent force main capacity continues to
enable increased NPDES capacity from 10 MGD to 16 MGD.
Re -NINE@
JUN 22 2011
pDoEf NNRr-UVATr-R Wilk{ I Y

The CFPUA is engaged in a two phase project to increase effluent discharge
capacity. The first phase (2007) installed a second separate and discreet
outfall/diffuser within the Cape Fear River as well as additional piping and valving at
the downstream end of the force main. The second phase (2011) involves installing
additional piping and valving between the phase 1 project and the WWTP at the
upstream end of the force main. With the minor exception where a single larger
section of effluent force main was installed, these projects will create a dual effluent
force main throughout its entirety between the WWTP and the two
outfalls/diffusers. The original 001 outfall remained in service until 08-15-2007
when it was temporarily taken out of service awaiting the second phase of work;
the newer 002 outfall has remained in service since that time.
Section A.7 of the current NC0023965 NPDES permit authorizes effluent sample
collection upstream of any flow split to effluent pump stations or discharge force
mains. Due to collecting the single effluent sample and relative proximity of
effluent lines and outfalls, DWQ decided to designate and regulate the discharge as
a single outfall. Our DMRs have reported all discharges as if they had occurred
through the 001 outfall. We would appreciate DWQ clarifying the following issues:
1. How does DWQ advise us to identify, permit, and report data for the two
effluent outfalls?
2. Does DWQ prefer that we refer to a 001 outfall and eliminate any/all
references to the 002 outfall?
3. Does DWQ prefer that we differentiate the discharge in any way if either one
or both of the outfalls are in service? If so, how should these three situations
(001; 002; 001 + 002) be referenced on DMRs?
As part of our permit renewal, I am requesting a reduction in effluent monitoring
frequency. We have provided data to the NC Water Quality Association which was
used to evaluate whether reduced effluent monitoring frequencies would yield
consistent, representative data. Their conclusion in a summary letter submitted to
NC DWQ on February 22, 2011 was that "... a reduction in routine monitoring
would save money and staff resources while still fully and accurately characterizing
POTW effluents." Their letter along with attachments included sufficient proof that
reduced effluent monitoring frequency can provide sufficient data to characterize
the water quality being discharged from most Major POTWs, including the James A.
Loughlin WWTP.
I am requesting a reduction in monitoring frequency for the following: BOD, TSS,
NH3 as N, and Enterococcus from 5 days/week to 2 days/week; toxicity from
quarterly to annually; and priority pollutants from annually to three monitoring
events conducted during the last three years of the five year permitted time period.

CFPUA staff review of discharge monitoring data for the James A. Loughlin WWTP
indicates a consistent, high quality discharge supporting our request. Our
compliance history has been excellent regarding permit limits and aquatic toxicity
testing requirements. Cost savings associated with a reduction in monitoring
frequency will be helpful with meeting other compliance obligations for our
wastewater treatment facility.
Please let me know if there are any questions or whether the application is deemed
complete. If all considerations are otherwise in order, we await receipt of a draft
permit for our review.
Sincerely,
Matthew W. Jordan PE

Cape Fear Public Utility Authority
James A. Loughlin (Northside) WWTP
Water Balance
Narrative Description
The Cape Fear Public Utility Authority (Authority) has several remote wastewater pump stations
that serve the James A. Loughlin (Northside) WWTP. Flow enters the WWTP site via three force
mains which combine at the new screening/grit removal facility.
Preliminary treatment effluent (PTE) flows by gravity to two primary clarifiers. A primary clarifier
bypass line is provided. Primary sludge and primary scum are pumped to the anaerobic digesters.
Primary effluent (PE) flows by gravity to the new aeration tanks where it combines with return
activated sludge (RAS) from the RAS pump stations. The mixed liquor (ML) is distributed to the
aeration tanks for biological treatment.
The effluent from the aeration tanks is distrluted proportionally to the four secondary clarifiers.
RAS is pumped back to the aeration tanks by RAS pump stations 1 and 2. Waste activated sludge
is wasted out of the RAS pump station discharge header and is gravity belt thickened prior to
pumping to the anaerobic digesters.
Secondary clarifier effluent (SCE) flows by gravity to the new tertiary fitters. Backwash reclaim
water from the filters is returned to the head of the aeration tanks.
Filtered effluent flows by gravity to the UV 'disinfection facility. The plant effluent is disinfected
in four UV channels and is metered with a parshall flume at this location.
UV effluent flows to the two effluent pump station which pump plant effluent to the Cape Fear
River. Either of the two pump stations has adequate capacity to pump the design average plant
effluent flow of 16 mgd. At the hydraulic peak flow of 40 mgd, both stations are required.

Cape Fear Public Utility Authority (CFPUA)
2011 NPDES Permit Renewal Application
CFPUA Sludge Management
Introduction
The Cape Far Public Utility Authority (CFPUA) was created by the City of
Wilmington, NC and New Hanover County, NC on July 1, 2008 to consolidate
provision of water and wastewater services within their combined service areas. Its
core principles are stewardship, sustainability, and service, and its mission is to
provide high quality service in an environmentally responsible manner while
maintaining the lowest practicable cost. The Authority strives to provide the safest
and highest quality water and wastewater services with heightened consideration of
the unique environment within which it operates and the efficiency and
effectiveness of service as it Impacts its customers whose user fees are its sole
funding source.
The Cape Fear Public Utility Authority (CFPUA) operates and maintains three
wastewater treatment plants (WWTP) and two water treatment plants
(WTP) - the James A. Loughlin WWTP (Northside Wastewater Treatment Plant -
NSWWTP), the M'Kean Maffitt WWTP (Southside Wastewater Treatment Plant -
SSWWTP), the Walnut Hills Wastewater Treatment Plant (WHWWTP), the Sweeney
Water Treatment Plant (SWTP), and the Nanofiltration Water Treatment Plant
(N FWTP).
Residuals sources within these facilities include NSWWTP digested residuals,
SSWWTP digested residuals, WHWWTP digested residuals, SWTP alum residuals,
and NSWWTP digestion system, SSWWTP digestion system, and SWTP water
treatment tankage contents removal associated with periodic maintenance
campaigns. Residuals produced by these facilities are processed and managed in
accordance with NCDENR Permit WQ0001271 governing land application of Class B
wastewater residuals and Permit WQ0011869 governing distribution of Class A
wastewater residuals. As applicable, and in conformance with all regulatory
programs/authorizations, the CFPUA also supports a process of receiving non-
CFPUA residuals for processing and disposal under its residuals permits, including
any modifications necessary to enable and support this practice.
The NSWWTP is a 16 million gallon per day (MGD) advanced treatment level facility
located at 2311 N. 23rd Street in Wilmington, NC. It was originally placed into
service in 1970 as an 8 MGD secondary treatment facility, and many improvements
have been incorporated in the intervening period. Construction is complete on an
$80,000,000 plant expansion/upgrade project begun in 2005. Liquid treatment
processes installed at this facility include screening, grit removal, primary
sedimentation, activated sludge secondary biological treatment, filtration, and
ultraviolet (UV) disinfection. Solids treatment processes include gravity belt

a
thickening, anaerobic digestion, and belt filter press dewatering. The liquid leaving
the plant (effluent) is of extremely high quality as set forth in the facility's National
Pollutant Discharge Elimination System (NPDES) permit limits and is currently
returned to the environment by discharge to the Cape Fear River. Solids/residuals
produced within the plant's processes are stabilized to North Carolina Class B land
application standards and are returned to the environment as a soil amendment
applied to nearby agricultural lands. Residuals generated within the
CFPUA's Sweeney Water Treatment Plant (SWTP) are pumped to the NSWWTP for
processing.
The SSWWTP is a 12 MGD secondary treatment level facility located at 3436 River
Road in Wilmington, NC. It was originally placed into service in 1972 as a 6 MGD
facility serving the City of Wilmington. It was later expanded to 12 MGD to serve
New Hanover County and the Town of Wrightsville Beach, and other improvements
were also incorporated throughout the intervening period. Improvements in
capacity and level of treatment provided have been planned and are currently
under design. Liquid treatment processes currently installed at this facility include
screening, grit removal, primary sedimentation, trickling filtration and activated
sludge secondary biological treatment, secondary clarification, chlorine disinfection,
and sodium bisulfite dechlorination. Solids treatment processes include gravity belt
thickening, anaerobic digestion, and belt filter press dewatering. The liquid leaving
the plant (effluent) is of high quality as set forth in the facility's National Pollutant
Discharge Elimination System (NPDES) permit limits and is currently returned to
the environment by discharge to the Cape Fear River. Solids/residuals produced
within the plant's processes are stabilized to North Carolina Class B land application
standards and are returned to the environment as a soil amendment applied to
nearby agricultural lands. Additionally, they can be processed to North Carolina
Class A Product/Distribution standards using alkaline stabilization.
The WHWWTP is a 0.1 MGD advanced treatment level facility located at 17 Little
Creek Road in Wilmington, NC. It was originally placed into service in 1970. Liquid
treatment processes currently installed at this facility include activated sludge
biological treatment, secondary clarification, filtration, chlorine disinfection, and
calcium thiosulfate dechlorination. Solids treatment processing consists of aerobic
digestion. The liquid leaving the plant (effluent) is of extremely high quality as set
forth in the facility's National Pollutant Discharge Elimination System (NPDES)
permit limits and is currently returned to the environment by discharge to the
Northeast Cape Fear River. Solids/residuals produced within the plant's processes
are stabilized to North Carolina Class B land application standards and are returned
to the environment as a soil amendment applied to nearby agricultural lands.

CFPUA Residuals Permits
The CFPUA currently possesses two residuals permits - Class A Residuals Permit
WQ0011869 and Class B Residuals Permit WQ0001271.
The Class A Permit allows the conversion of a maximum of 3,500 DTPY of residuals
from the NSWWTP, SSWWTP, and SWTP into a maximum of 7,000 DTPY of Class A
EQ residuals for distribution using an alkaline stabilization process/system located
at the SSWWTP. No residuals were processed through this system during CY 2009.
This permit expires on 02.28.2014.
The Class B Permit allows land application of a maximum of 7,300 DTPY of residuals
cake from the NSWWTP, SSWWTP, SWTP, and WHWWTP onto permitted sites.
During 2009, approximately 23,013 CY of cake from the NSWWTP, SSWWTP, and
SWTP were applied onto a total of 548.0 acres on 31 sites. A total inventory of
2,764.40 acres on 119 sites is currently identified within this permit. The permit
expires on 05.31.2014.
As currently practiced in accordance with WQ001271, NSWWTP and SSWWTP
residuals receive 40 CFR 503.32(b)(3) Class B, Alternative 2 PSRP (Anaerobic
Digestion) Pathogen Reduction (PR) and 40 CFR 503.33(b)(1) Vector Attraction
Reduction (VAR) (Minimum 38% Volatile Solids Mass Reduction) processing .
WHWWTP residuals receive 40 CFR 503.32(b) (2) Class B, Alternative 1 PSRP

(Seven sample GM FC<2,000,000 colonies/g TS dry weight basis) Pathogen
Reduction (PR) and 40 CFR 503.33(b) (3) Vector Attraction Reduction (VAR) (LT
15% additional volatile solids reduction after 30 additional days aerobic digestion)
processing; they can also be reprocessed through the NSWWTP anaerobic digestion
process. PR - and VAR - processed WWTP residuals are dewatered and blended
with dewatered WTP residuals, and land applied upon approved residuals
application sites. NSWWTP anaerobically digested residuals, WHWWTP aerobically
digested residuals, and SWTP alum residuals can be separately dewatered at
NSWWTP and separately transported to SSWWTP where they are blended with
dewatered SSWWTP anaerobically digested residuals. They can also be co -mingled
co-dewatered, and co -transported. Occasionally, as conditions warrant, these
residuals may receive additional alkaline stabilization processing at
SSWWTP in the form of 40 CFR 503.32 (a) (4) Class A, Alternative 2 (Biosolids
Treated in a High pH -High Temperature Process) Pathogen Reduction (PR) and 40
CFR 503.33(b)(6) Vector Attraction Reduction (VAR) (Alkaline Addition under
Specified Time and pH Conditions) in accordance with WQ0011869 to yield an
exceptional quality Class A product suitable for unrestricted distribution.

and performance may be found in its annual residuals management reports.
CFPUA Residuals Management Contracting
Including the experience of its predecessor (the City of Wilmington) in residuals
management contracting, the CFPUA has been involved in contracting selected
residuals management services for approximately 20 years. Initially, liquid
residuals disposal was practiced, but cake residuals disposal has been the preferred
disposal method for most of this period.
In continuing this approach, it is important to note the following goals:
• The contract must be able to accommodate changing needs and
requirements. Factors such as wastewater infrastructure, regulatory
impacts, and market/economic climate must receive continuous assessment
and may result in changing technologies and quantity and quality of
residuals.
• Due to the many regulatory and economic influences exerted beyond its
direct control, the CFPUA embraces a policy of flexibility and diversity in its
overall residual management strategy through development of other
residuals processes and products.
• The CFPUA encourages the sharing of contract risk and benefit between
CFPUA and the contractor, including use of innovative, creative residuals
management approaches to accomplish this.
The current contract provides for various services to be provided over an initial
three year period followed by two additional one year options for a possible total of
five years. The initial three year period will cover CY 2011 - 2013; if elected, the
first one year option will cover CY 2014 and, if elected, the second/last one year
option will cover CY 2015 and expires 12.31.2015.

Various services are offered under the current contractual arrangement, including
operation and maintenance of selected residuals processing equipment at the
NSWWTP and the SSWWTP; inter -plant residuals cake transport; cake unloading,
blending, storage, and reloading; cake transport to, unloading, storage, reloading,
and land application (discing; incorporation) at permitted sites; where required,
lime addition at certain sites; limited specified Class A product production,
marketing, and distribution; regulatory monitoring; administrative support services
(CFPUA permit administration/maintenance; site inventory additions and deletions;
annual residuals report for USEPA and NCDENR; agronomic and analytical
services); product sale/revenue generation; inter -plant liquid residuals transport;
WWTP digester maintenance cleanout; WTP process tank maintenance cleanout;
and mobile dewatering.
Contract bids are accepted for various levels of technical services - WWTP
mechanized equipment O&M, land application, or both/all - with all pricing including
related program support/administrative services. The pricing structure includes a
base monthly charge with a $/CY surcharge applied once the throughput exceeds a
20,000 CY annual threshold. Other pricing includes $/gallon charges applicable to
inter -plant liquid residuals transport, WWTP digester maintenance cleanout, WTP
process tank maintenance cleanout, and mobile dewatering. Invoices are rendered
monthly and pricing is adjusted quarterly based upon quarterly changes in the
USDOL BLS Consumer Price Index - All Southern Urban Consumers.
