Footnotes (continued):
(3) For the purposes of this permit, summer is defined as the period from April 1 through October 31 and winter is defined as the period from
November 1 through March 31 of each year.
(4) The monthly average effluent BOD; and Total Suspended Solids concentrations shall not exceed 15% of the respective influent values
(85% removal).
(5) The annual mass loading for total nitrogen for Outfall 101 shall be monitored and calculated as prescribed in Condition A.(3.).
(6) The annual mass loading limit for total nitrogen shall become effective with the calendar year beginning on January 1, 2003 unless it is
provisionally waived per Condition A.(4.), :'annual Limits for Total Nitrogen.
(7) See Condition A.(5.), Acute Toxicity Permit Limit.
(8) A daily maximum total residual chlorine (TRC) limit has been added to the permit. See the attached total residual chlorine policy memo for
details. The facility is allowed 18 months from the effective date of the permit to comply with the TRC limit. This time period is allowed in
order for the facility to budget and design/construct the dechlorination or alternative disinfection systems.
A. (2.) INSTREAM MONITORING
Instream monitoring requirements in this NPDES permit shall be provisionally waived so long as the
Permittee remains a member of the lower Neuse Basin Association and the Association continues to
function as approved by the Division and the Environmental Management Commission. If the Permittee
does not participate in the Association or if the Association ceases to function, the instream monitoring
requirements in this permit become effective immediately; and the Division may reopen this permit by
administrative letter to establish additional instream monitoring requirements it deems necessary to
adequately characterize the effects of the discharges on water quality in the receiving stream.
A. (3.) TOTAL NITROGEN MONITORING
The Permittee shall calculate the annual mass loading of total nitrogen as the sum of monthly loadings,
according to the following equations:
(a) Monthly Mass Loading (lb/mo) = TN x Q x 8.34
where: TN = the average total nitrogen concentration (mg/1,) of the
composite samples collected during the month at each outfall
Q = the total wastewater flow discharged during the month at each
outfall(MG/mo)
8.34 = conversion factor, from (mg/I, x MG) to pounds
(b) Annual Mass Loading (lb/yr) = E (Monthly Mass Loadings) for the calendar year
The Permittee shall report the total nitrogen concentration for each sample and the monthly
mass loading in the appropriate self -monitoring report and the annual mass loading of total
nitrogen in the December self -monitoring report for the year.
A. (4.) ANNUAL LIMITS FOR TOTAL NITROGEN
(a) The Neuse Nutrient Management Strategy rule for point sources (15A NCAC 2B. 0234)
provides that annual mass limits for total nitrogen shall be included in the permits for all
dischargers with permitted flows (as defined in the Strategy) greater than or equal to 0.5 MGD
and that those nitrogen limits, including the limits in this permit, shall become effective with
the calendar year beginning on January 1, 2003.
(b) The Neuse rule also provides that members of a group compliance association shall not be
subject to individual annual mass limits for total nitrogen. At the time of permit issuance, the
Permittee had expressed interest in joining such an association. Accordingly,
(1) the total nitrogen Limit in Conditions A.(1.) - (2.) of this permit is deemed waived
provided that the following conditions are met:
(i) a formal agreement between the association and Environmental Management
Commission, as outlined in 15A NCAC 2B. 02343P is established and is in effect; and

r
Permit NCO025348 r'
(ii) the Permittee is a party to said agreement; and
(iii) the association and the Permittee substantially conform with the agreement.
(2) So long as the total nitrogen limit in Conditions A.(1.) - (2.) is waived, the group nitrogen
allocation established pursuant to the agreement referenced above and any subsequent
amendments is hereby incorporated as an enforceable part of this permit.
(c) If the Division determines, at any time during the term of this permit, that these conditions are
not being met, it shall notify the Permittee in writing of this determination and of its basis. The
consequence of such a determination shall be that the Permittee's annual mass limit for total
nitrogen and its effective date shall be reinstated immediately. The Division shall accept and
consider written responses received from the Permittee and/or the association within thirty (30)
days of the original notice before making a final decision and will provide that decision in
writing.
(d) The Permittee shall notify the Division in writing within five (5) working days if, at any time
during the term of this permit, the Permittee elects not to join the association, or if it withdraws
or otherwise loses its membership in the association. Notification shall be sent to:
NCDENR / Division of Water Quality / NPDES Unit
1617 Mail Service Center
Raleigh, NC 27699-1617
A. (5.) ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
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 Fathead Minnow (Pimephales promelas) 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 March, June, September, and December.
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
TGE6C. Additionally, DWQ Form AT-2 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later
than 30 days after the end of the reporting period for which the report is made.
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 Branch at the address cited above.

s
t Permit NCO025348
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.
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.
A. (6) NON -DETECTION REPORTING AND DETERMINATION OF COMPLIANCE
When pursuant to this permit a pollutant analysis is conducted using an approved analytical protocol with
the appropriate minimum detection level and a result of "non -detectable" or "below quantitation limit" is
obtained, the Permittee shall record that result as reported. For the purpose of determining compliance
with a permit limit for the pollutant, the numerical value of that individual analytical result shall be zero.

Summa
The New Bern wwrp is a major municipal plant operating in Craven County. The facility- serves 24,400
people in New Bern and discharges to the mainstem of the Neuse River. In August 2003, the facility
completed installation of a diffuser as part of major upgrade and expansion. The main purpose of the
upgrade was to install biological nutrient removal systems for both nitrogen and phosphorus. The previous
permit authorized expansion to 6.5 MGD.
According to the Basinwide Water Quality Management Plan for the Neuse, the primary water quality
considerations for point sources in the basin are discharges of (1) oxygen -demanding substances and (2)
nutrients.
The Modeling Unit has evaluated the impact of increased wastewater flows upon dissolved oxygen levels in
the river, using a QUAL2E model already developed for the Neuse River. The results show that increasing
wastewater discharges can have a pronounced impact on D.O. levels, and the Division has adopted a policy
of implementing limits of 5 mg/L BOD and 1 mg/L ammonia along the Neuse mainstem.
The entire Neuse River Basin is classified as Nutrient Sensitive Waters. The Environmental Management
Commission adopted Nutrient Management Strategy rules in December 1997, with revisions in March 2000.
The rules set nitrogen discharge limits for all point source dischargers larger than 0.5 MGD; and they extend
the coverage of phosphorus limitations to some dischargers not previously affected by the rules.
Nutrient Management Requirements
Under the new Nutrient Management Strategy rule, the City's discharge to the Neuse River is subject to a
total nitrogen (TN) limit. The City has joined a group compliance association, as allowed under the rule, in
which case the TN limit will be met by collective efforts of the association.
Compliance History
During recent years the facility has been expanding and upgrading to provide a high degree of biological
nutrient removal of both nitrogen and phosphorus. During construction, facility has been operating under
Special Order by Consent (SOC) and experienced difficulties meeting the SOC limits. The SOC was revoked

9
in July 2003 after completion of the upgrade. The facility has been meeting all permit limits after new
treatment units have been installed.
The most recent compliance evaluation inspection conducted on November 6, 2003 indicated that all records
and reports are up to date and the facility appeared to be well maintained and operated. It was found to be in
compliance with permit limits.
Wastewater Reuse & Groundwater Recharge
The City has explored reuse as one means of reducing its direct discharge flows to the river and has requested
authorization to make use of the nearby Glenburnie quarry (see permit map) for this purpose. Since
dewatering was halted when the quarry closed in recent years, the quarry pit has filled to form a lake as the
groundwater level has returned to normal. The City proposes to construct berms (approx. 11 ft.) around the
quarry and to discharge reuse -quality water to the lake. The water will then infiltrate into the ground, helping
to recharge the surrounding aquifer. There is considerable uncertainty on several key questions; for instance,
how much water can infiltrate through this system? How much will eventually reach the Neuse River? How
much of the nutrients or other materials in the wastewater will move into the aquifer or the river? How will
the discharge affect water quality in the lake?
This system is expected to reduce the amount of nitrogen discharged to the river (and eventually the estuary).
This could be taken into account in measuring the City's TN load into the river and estuary. However, given
the uncertainty surrounding the project, it is not possible at this time to know how to estimate the amount of
nitrogen permanently diverted from the river. The quarry project will serve to demonstrate the actual
performance of the system and may provide enough understanding to allow those estimates to be made.
The City is developing a Lake Management Plan that will outline a strategy for preventing degradation of
water quality in the lake. The plan will include a monitoring schedule and will identify specific actions to be
taken to ensure the lake is not adversely impacted.
Hydraulic Treatment Capadty
Normally, a permit's flow limitation serves two purposes: (1) it limits the amount of wastewater (hence, the
pollutant load) discharged to the river, and (2) it prevents the flows through the treatment plant from
exceeding the approved Average Design Flow. Both limits are essential to protecting water quality. Normally,
a single flow limit is sufficient to meet both needs_
Confusion can arise when a facility diverts some portion of its effluent for reuse or other non -discharge
options. A single flow limit no longer meets both needs, and it becomes necessary to distinguish between
plant flows and discharge flows and to limit both.
This permit proposes separate flow limits for the 'vY/NVTP (measured at the influent) and for Outfall 001, in
order to make the distinction between the two flows and ensure that flows do not exceed either the receiving
stream's assimilative capacity or the plant's hydraulic capacity. It also proposes continuous monitoring of the
quarry flow to ensure accurate measurement there.
Quarry Discharge. The City has applied for a non -discharge permit, Application No. WQ0017635, to reuse
any or all of its treated effluent (effectively limited by infiltration capacity in the quarry system). Effluent
limitations, monitoring requirements, sampling point(s), and other conditions for reuse will be established in
the non -discharge permit. The NPDES permit does not include an effluent page for reuse; instead, it simply
authorizes the diversion on the Supplement to Cover Page and refers to additional requirements to be found
in the non -discharge permit for the reuse water flows. This permit has been developed assuming 10% of the
effluent will discharge to the river with minor provisions related to measuring flows though the %YAYrIT as
well as discharges to both potential sites.
Toxicitv TestinLy:
Type of Toxicity Test: Acute P/F
Existing Limit: 001: Acute P/F @ 90%
Recommended Limit: 001: Acute P/F @ 90%
Monitoring Schedule: March, June, September, and December
Test organism: Fathead Minnow (Pimepbales promelas)
This facility has failed it's toxicity test on numerous occasions prior to the installation of the upgraded
equipment. It has been passing the test since July 2003.

Reasonable Potential Analysis:
Reasonable potential analyses were conducted for cadmium, cyanide, chromium, lead, selenium, silver,
copper, zinc, phenols, mercury, and nickel (see attached). The following parameters are monitored
through the permit: copper, cyanide, silver, zinc, selenium, phenols, mercury. This permit will continue to
require the City to implement its approved pretreatment program.
Proposed Changes:
• Monitorin,9 Frequencies. The monitoring frequency for CN has been reduced to 2/Month due to the
removal of the permit limit.
• Limits: Weekly average limit for ammonia nitrogen has been added to the permit. A daily maximum
total residual chlorine (TRC) limit has been added to the permit. Limit for CN has been eliminated based
on the RPA analysis conducted with a new effluent data. The TN limit has been increased to 58,569
lb/year (annual mass loading) to include the allocation from two smaller facilities that have connected to
the City's collection system.
• Priority pollutant monitoring on an annual basis has been added to fulfill the permit application
requirement in the future.
Proposed Schedule for Permit Issuance:
Draft Permit to Public Notice: April 14, 2004 (est.)
Permit Scheduled to Issue: June 11, 2004 (est.)
State Contact:
If you have any questions on any of the above information or on the attached permit, please contact Sergei
Chernikov at [phone] ext. 594.
REGIONAL 0I-1-ICE COMMENT:
Staff report recommended re -issuance of the permit (March 4, 2003).

Hi, Ken -
Sorry I didn't get back to you last week - I just now read your e-mail and draft cover
letter. But the letter looks good, and I only need to comment on one part of it.
On page 2, you mention the TN limit in the City's NPDES permit. To clarify,
• the City is allowed to discharge TN whether they are an Association member or
not. If a member, their TN discharge is governed by the Association's NPDES
permit NCC000001 (N - C - C - five zeros - 1); otherwise, by their NPDES
permit NC0025348. (The limits should be the same in both permits.)
• the TN limit in the City's 2001 permit is, as you wrote, 52,940 lb/yr. This value
will change in the next permit to include the allocation from smaller facilities
that have connected to the City's collection system since we issued the 2001
permit.
The NC0025348 permit was last issued in 2001 and is due for renewal this year. Teresa
Rodriguez is the permit writer this time. The permit picture is getting more
complicated, what with treated wastewater going to the river (counts toward their TN
limit), the quarry (also counts), and the nursery (doesn't count). We will need to have
the City report both the river and quarry discharge flows - another first for New Bern -
until we approve their GW model for estimating credits. Do you have any idea
whether they are still planning to do that ?
Congratulations on getting this one out the door. It has been "in the works" for a
l-o-o-o-ong time! I bet it will feel good to work on something else for a change. Enjoy!

Re: Draft New Bern Quarry & Turn Farm Permit Cover L...
Quarry project, which includes reclaimed water irrigation on a local Turf Farm. Can
you review this cover letter to make sure we're not saying anything here out of line?
I would appreciate any feedback you have, or if we're saying something wrong,
particularly when we talk about nitorgen credits for the discharge into the Neuse
River. We've never done this before, and maybe we're not saying it right, not sure.
If you could make comment by the end of this week or sooner, that would be great.
Thanks alot!

Subject: Evaluation of Copper and Zinc per DWQ's Copper and Zinc Action
City of New Bern WWTP
NPDES No. NCO025348
Craven County
Dear Mr. Hartman:
1 Policy
This office has completed a review of the subject document prepared by Aquatic Sciences Consulting
dated February 26, 2002. Due to effluent toxicity permit limit violations that occurred during January and
February 2001, the facility received notification of DWQ's Copper and Zinc Action Level Policy. An evaluation
of reasonable potential to violate instream action levelsTow for these parameters was conducted by the NPDES
Unit. The analysis indicated that reasonable potential existed for the facility to violate instream action levels for
copper.
Three separate rounds of selected TIE treatments using EDTA and sodium thiosulfate were conducted.
The first round of testing was performed with an effluent sample collected on November 13-14, 2001. Initial
sample total metal copper and zinc concentrations measured 15 ug/L and 31 ug/L, respectively, with a 96-h LC50
of 30.3%. EDTA treatments were conducted at concentrations of .03625 mg/L, 0.145 mg/L and 5.8 mg/L with
corresponding 96-h LC50 values of 50.9%, 38.6% and 52%. Sodium thiosulfate treatments were performed at
concentrations of 1.1875 g/L, 2.375 g/L and 4.75 g/L with corresponding LC50 values of 35.4%, <25% and
<25%. When asked about the non-standard concentration response using 0.145 mg/L EDTA, the Town's toxicity
consultant indicated that concentrations for EDTA were inadvertently set too low. We were informed that
reagents were changed for the subsequent December and February 2002 TIE trials and that EDTA and sodium
thiosulfate treatment concentrations were adjusted accordingly. It is our opinion that total and soluble copper/zinc
values for the November trial were at concentrations which should not have contributed to effluent toxicity.
The second round of TIE treatments were conducted using an effluent sample collected on December 4-5,
2001. Initial sample total metal copper and zinc concentrations measured 16 ug/L and 40 ug/L, respectively with
a 96-h LC50 of 35%. EDTA addition at 0.90 mg/L and 187.5 mg/L significantly reduced toxicity (non -
overlapping confidence intervals). The report notes that LC50 values for the 3.56 g/L and 7.13 g/L thiosulfate
treatments measured <25% with no confidence intervals. The investigators concluded that sodium thiosulfate
treatment LC50 values could be within the confidence limit of the baseline test based on the degree of mortality
observed in the raw data for the 25% test concentration. We believe the December data are useful for discerning
whether copper was a source of observed toxicity and agree with the investigators that test results are not
consistent with copper toxicity. Total and soluble zinc concentrations were below the 50 ug/L action level and, in
our opinion, most likely did not contribute to effluent toxicity in this sample.
The third round of TIE treatments were conducted using an effluent sample collected on February

12-13, 2002. Initial sample total metal copper and zinc concentrations measured 17 ug/L and 52 ug/L,
respectively, with a 96-h LC50 of 33%. EDTA addition did not significantly reduce toxicity. Sodium
thiosulfate addition at 2.97 g/L significantly reduced toxicity, compared to baseline. The investigators
indicate that toxicity reduction in the February sample was most likely due to reduction of total residual
chlorine (0.28 mg/L) in the sample. Total copper and zinc concentrations measured 17 ug/L and 52 ug/L
respectively. Soluble copper and zinc concentrations measured 6.3 ug/L and 20 ug/L. The investigators
state that results from the February TIE are not consistent with the presence of copper and zinc toxicity.
The report mentions that although chlorine is the likely toxicity reduced by sodium thiosulfate in
the February TIE treatment, test results are also characteristic of silver and selenium. No data was
available for selenium yet silver (soluble) was present at a concentration of 2.1 mg/L compared to the
Action Level of 0.06 mg/L (per conversation with facility's contractor, concentration units should have
been ug/L and not mg/L, as reported). The investigators suggest additional work to evaluate the potential
for silver to contribute to effluent toxicity.
In summary, copper toxicity is indicated if EDTA and sodium thiosulfate addition reduce
toxicity. Zinc toxicity is indicated if toxicity is reduced by EDTA addition. Based on the data provided
in this report, we believe that copper and zinc were not the primary toxicants in TIE treatments. Our
review of the facility's DMR effluent silver concentrations for calendar year 2001 January through
December 2001 shows silver concentrations ranging from non -detectable to 16 ug/L. Silver can be
introduced into the collection system through a number of activities including: photographic film
processing, X-ray equipment, hospitals, dental offices and unidentified IU wastestreams.
Based on results obtained from TIE treatments, our office does not recommend that the NPDES
permit be reopened to include copper and zinc permit limitations.

Re: Copper and Zinc Evaluation at the City of New Bern
o
Dear Mr. Matthews:
On behalf of the city of New Bern, Rick Diehl (SEWALABS) and I are requesting an extension to
the December 27, 2001 deadline for submittal of the report regarding our evaluation of the
contribution of copper and zinc to effluent toxicity at the city's wastewater treatment plant
(WWTP). We respectfully request an extension to February 28, 2002.
Our request is based on the need for further evaluation because (1) the dissolved form of copper
and the total and dissolved forms of zinc were not found at Action Level (AL) concentrations in
our test samples and (2) our interest in re-evaluating the reasonable potential analysis using
current valid copper and zinc effluent data. The initial results of our testing [using EPA's
Toxicity Identification Evaluation (TIE) procedures] indicate no contribution by copper or zinc to
the city's effluent toxicity. However, the data are not conclusive. We would like to discuss our
experimental design with you particularly our sampling approach, which shows copper and zinc
effluent concentrations below the ALs. Considering the relatively low copper and zinc
concentrations, we also propose to re-evaluate the reasonable potential analysis using current
data. One concern is the minimum detection limit for copper of <10 µg/L, which is above the
AL of 7 µg/L. It will he more accurate to use data based on a lower detection limit to fudge
reasonable potential.
We look forward to talking with you and Susan Wi son about our proposed work when we return
from Christmas holiday. Please call me [phone], if you have questions or comments.

Attached is the "Toxicity Reduction Evaluation Progress Report" for December 2001 that
is required by the Special Order of Consent (WQ99-017). I have outlined our efforts to
identify effluent toxicants and investigation of the source. I have included information
concerning the Pretreatment Program and the effects of demolition of plant processes.
The City of New Bern has been involved in an evaluation program under the direction of
Matt Matthews (DWQ Aquatic Toxicology Unit). The cost for the past two months has
been approximately $6000. I would like a review of our efforts and more direction in
follow-uy of the nroaram. It has been the recommendation of Mr. Matthews and
SIMALAB that a pilot plant be set up to verify the removal of toxicity for a plant that is
under construction at the present. The designing engineers have verified that removal of
ammonia will reach non -toxic levels. The Bardenpho Process appears to have,not
presented enough proof to satisfy the Toxicology Division. Now it has been purposed
that a pilot plant consisting of buckets and pails be set up at a cost of> $50,000._
This study has been initiated because the effluent has demonstrated toxic qualities. This
characteristic has been identified repeatedly as ammonia. A new plant is under
construction with biological nutrient removal. The toxicology study being preformed at
this time is using effluent, which is being treated by only one train of operation.
Engineering design for the plant has been decreased by one half. In addition, the units
that were demolished were emptied into the operating unit, compromising the treatment.
The contents of the 0.5 MG holding digester were pressed and the supernate was placed
back in the system. The effluent at this time is neither typical nor representative of
,ifritrittg for �xrsllEnre

effluent from the old treatment Plant. The influent has also been altered by the
introduction of other process water not typical to normal operation. The plant is operating
under a Special Order of Consent that relaxed the permit limits to allow the construction
of a new plant. I think that the Toxicology Unit should also consider these changes to
the process in their re uire . Thoughtless testing is reckless use of tax dollars.
Please review of our efforts and give more directions to the requirements that are needed
during this construction period. Please contact me should you need additional
information (252-636-4075).
