Subject: NPDES Permit Issuance
Permit No. NCO025348
New Bern Wastewater Treatment Plant
Craven County
Dear Mr. Hartman:
In accordance with the City of New Bern's application of September 30, 1998, and amended
application of May 18, 2000, for renewal of its discharge permit, the Division is forwarding herewith
the subject NPDES permit. This permit 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"Rlay 9, 1994.
The December 12 letter from City Engineer David Muse was the only response to the draft permit
during the 30-day public comment period. The final permit issued today includes the following
changes from the draft permit:
• Monitoring Reguirements, Existing Treatment Plant Monitoring frequencies for metals in
the existing treatment plant have been returned to monthly, as in the last permit.
Some metals found in the City's treated effluent are potentially of concern. The City will
need to monitor these closely to determine whether the discharge from the new treatment
plant has the potential to exceed water quality standards in the Neuse River. Increased
sampling frequencies for these parameters will become effective once the new treatment
plant is operational but do not serve a useful purpose at this time.
• Sludge Treatment. The Supplement to Permit Cover Sheet has been amended to change
"sludge drying beds" to "sludge filter press."
The following items are in response to other comments and questions in Mr. Muse's letter:
• Interim Limitations. The NPDES permit does not address the transition from the existing
treatment plant to the new plant. The Division plans to establish interim discharge limits,
monitoring requirements, and other requirements for the duration of the plant's
construction in the City's Special Order of Consent.
• Reporting During Periods of No Discharge. The Division expects to issue a separate, non -
discharge permit to establish requirements for the proposed quarry discharge. The permit
will call for the City to submit Discharge Monitoring Reports PMRs) for each permit, for
the full term of each permit. There may be times when the treatment plant will send all of

its treated effluent to the quarry and other times when the entire discharge will go to the
Neuse River. The City should report the actual flows to the quarry and to the river on its
DMRs (entering "zero" whenever appropriate) and should make every reasonable effort to
collect any required samples. The Division recognizes that during those periods with no
discharge it may not be possible to conduct the daily or weekly or monthly monitoring
specified in the permit.
• Nitrogen Limit. The nutrient management strategy rule for dischargers in the Neuse River
basin sets allocations for all dischargers with permitted flows at or above 0.5 MGD. The
rule requires dischargers to meet these limits by calendar year 2003 and does not provide
for compliance extensions due to construction schedules or other factors.
The nutrient rule allows any discharger to join a group compliance association, and the
individual limits for all members are waived in favor of a group limit. We expect the
association will be established before the end of 2001. If it is not formed by 2003, all of the
potential members will continue to be subject to their individual limits. The City should
make every effort to complete construction of the new plant as soon as possible to avoid
any possibility of exceeding whichever nitrogen limit is in effect in 2003.
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.
Please take notice that 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 governmental permit.
If you have any questions concerning this permit, please contact Mike Templeton at telephone
number [phone], ext. 541.

(8) See Condition A.(7.), Chronic Toxicity Permit Limit.
(9) The Division recognizes a Practical Quantitation Limit (PQI) of 0.2 ug/L for mercury analyses. See Condition A.(8.).
A. (3.) 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. (4.) 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/I,) of the
composite samples collected during the month at each outfall
Q = the total wastewater flow discharged during the month at each
outfall(IVIG/mo)
8.34 = conversion factor, from (mg/L X IVIG) to pounds
(b) Annual Mass Loading (lb/yr) = 1: (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. (5.) 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-(L) - (2.) of this permit is deemed waived
provided that the following conditions are met:

Permit No. NC0025348,
_ z
(i) a formal agreement between the association and Environmental Management
Commission, as outlined in 15A NCAC 2B. 0234, is established and is in effect; and
(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. (6.) TOTAL PHOSPHORUS LIMITS
(a) The Neuse Nutrient Management Strategy rule for point sources (15A NCAC 2B. 0234)
prescribes a quarterly average, total phosphorus (TP) limit of 2.0 mg/I, for all existing
dischargers with permitted flows (as defined in the Strategy) greater than or equal to 0.5 MGD.
The rule also prescribes a more stringent 1.0 mg/L TP limit for all new facilities or for existing
facilities expanding their discharges above their 1995 permitted flows. The total phosphorus
limits, including the limits in this permit, shall become effective January 1, 2003.
(b) The Neuse rule also provides that, for any member of a group compliance association which
increases its discharge above its 1995 permitted flow, the TP limit shall remain at 2.0 mg/L. At
the time of permit issuance, the Permittee had expressed interest in joining such an association.
Accordingly, upon expansion of the treatment facility above 4.7 MGD average design flow, the
1.0 mg/I, total phosphorus limit in Conditions A (2.) of this permit is deemed waived and the
TP limit shall remain at 2.0 mg/L, provided that the following conditions are met:
(1) a formal agreement between the association and Environmental Management
Commission, as outlined in 15A NCAC 2B. 0234, is established and is in effect; and
(2) the Permittee is a party to said agreement; and
(3) the association and the Permittee substantially conform with the agreement.
(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 1.0 mg/L limit for total phosphorus 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:

A. (7.) 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 sel£ monitoring purposes must be obtained during
representative effluent discharge below all waste treatment. The tests will be performed during the
months of MarchJune, 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.
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. (8.) 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.
A. (9.) OUTFALL EXTENSION
No later than June 30, 2001, the Permittee shall submit for Division review an approvable proposal to
construct an outfall line into the main channel of the Neuse River in order to provide reasonable effluent/
stream mixing. The submittal shall include, at a nnimum, a project description, a discussion of design
considerations and recommendations, a list of permits and approvals required, plans and specifications for
the project, design calculations and other supporting information, and a schedule for completing
construction of the project by January 1, 2003.

The City of New Bern owns and operates a 4.7 MGD wastewater treatment plant and holds an
NPDES permit for the discharge of treated municipal wastewater to the Neuse River. The permit
was last issued March 31, 1994, expired March 31, 1999, and was administratively extended when
permits in the Neuse River basin were delayed. The permit was modified on November 23, 1994, to
reflect New Bern's membership in the Lower Neuse Basin Association, a monitoring coalition.
In October 1998, the City submitted its application for renewal of the NPDES permit. In May 2000,
it submitted a revised application, requesting authorization to expand the wastewater treatment plant
to 6.5 MGD average design flow. The City has also proposed to divert a portion of its treated
effluent to a quarry lake (formerly a Martin Marietta quarry, closed in recent years), which will be
used as a high -rate infiltration system. This system will provide recharge to the groundwater aquifer
and (indirectly) the Neuse River.
The Division proposes to re -issue the City's NPDES permit with effluent limitations for 4.7 and 6.5
MGD flows and with other appropriate terms and conditions necessary to protect the quality and
designated uses of the river. Conditions for the reuse/ infiltration of treated effluent in the quarry
system will be covered under a separate, non -discharge permit (Application No. WQ0017635), and
the Division proposes language in this NPDES permit to acknowledge the diversion of effluent and
to properly link the two permits.
BACKGROUND
Water Oual ty
The New Bern WV(ITP discharges to the mainstem of the Neuse River. 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.

y FACT SHEET - NPDES PERMIT City of New Bern
Page 2 NPDES No. NC0025348
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 would
normally be subject to a total nitrogen (TN) limit beginning in 2003. The City has expressed its
intent to join a group compliance association, as allowed under the rule, in which case the TN limit
will be waived. Instead of being subject to this limit, the City and other members of the association
will be responsible for working together to meet their collective TN limit.
Facility Description and Planned Improvements
The New Bern VVWT'P is a 4.7 MGD trickling filter system located adjacent to the Neuse River,
upstream of downtown New Bern. The plant discharges at the bank of the Neuse River just
upstream from the mouth of Rennys Creek, the main stormwater drainage for downtown New
Bern.
The existing treatment process consists of -
Mechanical influent screening and grit removal;
• Dual primary clarifiers;
• Dual trickling filters and secondary clarifiers;
• Dual chlorine contact chambers, dechlorination and re -aeration;
• Chemical feed for phosphorus removal; and
• Solids handling facilities: thickener, filter press, three (3) aerobic digesters, drying
beds, and dewatered sludge storage.
The plant was originally built in 1964 and expanded in 1991. In 1998, due to increasing problems
with toxicity in the plant effluent, the City requested speculative limits for an upgrade and expansion
to 6.5 MGD, to address both the compliance problem (improved treatment capability) and provide
for anticipated growth (increased capacity).
The City has since moved forward with its expansion plans. In Map 1999, it obtained a Finding of
No Significant Impact (FONSI) for the expansion. Plans and specifications for the new facilities are
presently under review by the Construction Grants and Loans Section.
The proposed expansion will completely replace the existing trickling filter system. It will employ an
advanced five -stage Carrousel-Bardenpho process and deep -bed effluent filters to provide a high
degree of biological nutrient removal of both nitrogen and phosphorus. It will include new
headworks and solids handling systems as well.

Compliance History
For most parameters, New Bern's compliance with its "monthly average" permit limits has been
reasonably good in recent years. The plant exceeded it flow limit in February 1998 and September
and October 1999, all of which were exceptionally wet months. The plant exceeded its BOD limit
once, in February 2000.
However, the plant failed its toxicity limit twelve times between January 1996 and July 2000,
including five times between March and July 2000. Ammonia and residual chlorine are the most
likely sources of the toxicity. The trickling filters do not nitrify consistently, and ammonia levels
average 10 — 15 mg/L in the effluent. Despite dechlorination, residual chlorine in the effluent
typically run in the range of 100 — 500 ug/L. Metals or other toxicants may also contribute to the
problem, but any impacts from them are probably masked by the effects of ammonia and/or
chlorine.
Wastewater Reuse & Groundwater Recharge
The City has explored reuse as one means of reducing its discharge flows 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 estimate
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.
PROPOSED PERMIT REQUIREMENTS
General
The draft NPDES permit includes effluent limitations and monitoring requirements for the existing
4.7 MGD treatment facility and for the planned 6.5 MGD facility, and acknowledges the proposed
quarry discharge and its Non -Discharge Permit. Because of the diversion of treated effluent to the
quarry/ reuse system, the permit also includes a limit for flow through the treatment plant itself, in
order to ensure that plant flows do not exceed its design capacity. The NPDES permit also includes
a TN limit and special conditions implementing the new Nutrient Management Strategy for the
Neuse River Basin.

Hydraulic Treatment Cgpacijy
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 WW 1'P (measured at the influent) and for Outfall
0015 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.
Effluent Limits and Monitoring Requirements
Outfall 001. The following table summarizes both the current and the proposed permit limits and
monitoring requirements for Outfall 001 (only monthly average limits are listed, except where
noted). The Division proposes to maintain the existing requirements for the trickling filter plant and
to establish more stringent limits for the new treatment system. The Division is currently developing
a Standard Order of Compliance with the City to establish interim requirements during the
construction of the new plant. The SOC, in effect, creates a bridge between the old and new limits.

The limits and monitoring requirements for metals and cyanide are based on a reasonable potential
analysis of Long -Term Monitoring Plan (LTMP) data, collected under the City's pretreatment
program from July 1997 through June 2000. The results indicate that some changes in limits and
monitoring requirements are warranted.
Cyanide. Twelve of 36 samples measured at or above the 5 ug/L detection limit, the highest of
these being 24 ug/L. The maximum concentration predicted from these would exceed both the
state standard of 5 ug/L after mixing (chronic impacts) and the '/a Final Acute Value (/2FAV)
prior to mixing (potential acute impacts). Thus, the acute criterion is the more stringent, and the
permit includes a daily maximum limit equal to the '/2FAV of 22 ug/L.
Other Metals. The monitoring results for arsenic, cadmium, chromium, lead, nickel, and
selenium indicate levels well below those that would cause exceedances of water quality
standards in the receiving stream. Thus, no limits are required, and the Division proposes to
delete monitoring requirements for these metals from the permit. These and other parameters of
interest will continue to be monitored under the City's LIMP.
The reasonable potential analysis assumes the entire permitted flow would be discharged to the river
under low -flow (7Q10) conditions, to evaluate the potential impacts to the receiving stream.
The permit includes nutrient limits as the result of new Nutrient Management Strategy rules for the
Neuse River Basin (715A NCAC 2B .0234), adopted in December 1997 and revised in February
2000.
Nitrogen. Under the new rules, the City receives a Total Nitrogen allocation of 52,940 lb/yr.
The allocation limits all of the City's discharges to surface waters under this permit and is
included as a discharge limitation. In the event the City joins a group compliance association, the
limit is waived so long as the City maintains its membership; and, in that case, the City and other
association members become responsible for meeting their combined allocations.
Phosphorus. The 2.0 mg/L Total Phosphorus limit is carried forward for the existing facility.
Under the new NMS rule, new or expanding facilities are subject to a 1.0 mg/L monthly average
Emit; and the new facility receives this limit. However, as with Total Nitrogen, the stricter limit is
provisionally waived so long as the City belongs to a group compliance association. Therefore,
the 4.7 and 6.5 MGD effluent sheets contain TP limits of 2.0 and 1.0 mg/L, respectively; and
the latter sheet refers to a special condition which includes the provisional 2.0 mg/L limit.
The permit includes instream monitoring requirements but waives them so long as the City
continues to participate in the Lower Neuse Basin Association, the cooperative monitoring effort
undertaken by many of the Neuse River dischargers.
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.

Subject: Draft NPDES Permit NCO025348
Dear Mr. Templeton,
December 12, 2000
I have reviewed the draft permit dated November 8, 2000 and received on November 17, 2000
and offer the following comments for your consideration:
1. For the existing plant, the permit is requiring testing for metals twice per month versus
our present requirement of once per month. The metals selenium and mercury are not
detectable in our head works analysis and the other metals are well below the monitoring
threshold. Since the present plant treatment is unchanged and metals do not appear to be
a problem, we request the permit require metals sampling once per month.
2. The permit for the existing plant includes an annual mass loading for total nitrogen. I
would like to point out the fact that the City of New Bern cannot control the actions of
the State or the Lower Neuse Basin Association (LBNA). In my mind, the proposition .
that the LBNA could dissolve before the new plant is constructed which by default would
leave the City in position of vulnerability. The present process is incapable of nitrogen
removal to the extent necessary to meet these specified limits.
3. The plant is in the process of design for upgrading to 6.5 million gallons per day. The
permits presented do not address the transition period from one plant process to the other.
According to the memories of my staff, a transitional period permit is issued to handle the
plant process requirements during the construction phase of the project and subsequent
,$frihing for ' ixrellenre

transition from the old process to the new plant process. We assume this transition will be
addressed in the Special Order of Consent previously presented for consideration by the
Regional Office of DWQ.
4. The proposed new plant monitoring requirements also include metals monitoring twice
per month. Our position concerning metals remains as stated above and request the
testing be reduced to once per month.
S. The permit is appears to assume the new plant being completed by January, 2003. The
SOC presented to DWQ outlines the construction completion by June, 2003. The dates of
completion for January 2003 were based upon our speculation that a permit to construct
would be issued by Construction Grants and Loans Section by December, 2000. The
SOC process must be completed before the permit will be issued. In my estimation an
SOC will not be completed until February, 2000 which will push the entire project back at
least three months. The SOC submitted for review did not include any additional time
which would be required if the construction sequencing were dictated to the General
Contractor. The construction sequencing has been a topic of discussion surrounding the
SOC request for additional flow.
6. The proposed effluent discharge to the New Bern Water Reclamation Project at the
abandoned Martin Marietta Quarry is not addressed in the draft permit. I understand the
State will issue a non4scharge permit for the project and will require separate monitoring
for Groundwater Standards. How will this effect the NPDES permit for days we do not
discharge to the river? What monitoring and reporting requirements will be required for
the NPDES permit when a condition of no flow to the river exist for days or months. I
ask this issue should be addressed and guidance provided in the draft permit for the new
process permit.
7. The Supplement To Permit Cover Sheet should be amended to change "sludge drying
beds" to "sludge belt press".
Thank you for the opportunity to address these issues. The major issue in our mind is the added
testing required for the metals. Unless an issue exists that I am unaware or overlooking, the metal
testing is a huge burden which is unjustified in our opinion.

Re: NCO025348 City of New Bem, Discharge Line & Diffuser Craven County
The Regional Office has taken the position that a new discharge line with a diffuser
should be required in the NPDES permit which grants the Cities expansion request.
The City is presently discharging wastewater at the bank of the river. The Region
believes during the plant expansion is the time to install a discharge system that
makes a reasonable good faith effort to utilize the full dilution of the Neuse River at
this point. The existing discharge system does not do this in the Regions opinion.
With the help of the Neuse River Emergency Response Team additional data has
been gathered to allow the Region to make a more detailed recommendation.
The point of discharge should be beyond the northeastern most point of the mouth
of Rennys Creek in order to maximize dilution.
The point of discharge should be at a minimum of six(6) foot depth of water at the
normal water level. This depth corresponds to an approximate distance of 912
foot from the bank of the river.
Please find attached information gathered for this recommendation

Comments on Plans and Specifications
City of New Bern
WWTP Expansion
General Comments:
1. With submittal of revised plan, provide an updated itemized cost estimate for the
proposed project. We recommend that prior to responding to these comments, a meeting
be set up with us to .discuss funding and project management issues.
2. Provide documentation that the sedimentation/erosion control measures _on the plans :have
been reviewed and approved by the DENR Division of Land. Resources, Land Quality
Section. This documentation is required before the plans and specifications can be
approved.
3. Provide documentation that any required air quality permit from the Division of Air
Quality for the Odor Control (Scrubber) System and the Lime Storage Silo has been
obtained
4. The project contract specifications must clearly state that "the facilities shall be
constructed in accordance with the NC Sedimentation Pollution Control Act. In addition,
the specifications must clearly state what the contractor's responsibilities shall be in
complying with these acts.
5. According to Mike Templeton of the NPDES Unit/Water Quality Section, the new
NPDES permit for the expanded 6.5 MGD flow will likely not be finalized until October
2000, at the earliest. The Authorization to Construct will likely not be issued until the
NPDES permit has been finalized.
6. This project should potentially include a discharge pipeline and diffuser into the Neuse
River, because of the following reasons. The current NPDES permit limits are based on
full dilution of the effluent with the Neuse River at the point of discharge. Areal
photographs of the area show that the effluent emanates out into the river and bends
towards the mouth of a small creek in front of a small peninsula to the east. This implies
that at least locally the effluent is not mixing well with the majority of the Neuse River.
Mike Templeton of the NPDES Unit/Water Quality Section (919-733-5083, X-541) will
be studying this matter further with regard to the impact on the new permitted limits. Al
Hodge of the Washington Regional Office/Water Quality Section has been in contact
with David Muse/City of New Bern with regard to this issue also. There will likely be a
trade-off between more stringent permit limits with no discharge pipeline/diffuser, and
somewhat less stringent permit limits with the discharge pipeline/diffuser. We realize

that the design of an effluent pipeline/diffuser will likely necessitate the need for an
effluent pump station to overcome the headlosses in the pipeline/diffuser. (see Comment
#8 below for effluent pump station issues.)
7. Regarding the proposed Five -Stage Carrousel Bardenpho System, we agree in principal
that the proposed system in combination with the deep bed effluent filters should be
capable of meeting effluent limits of 5.0 mg/1 BOD5, 3.0 mg/1 total nitrogen, and 1.0 mg/1
total phosphorus. We have the following comments/questions:
(a) We note that the oxidation ditch flow splitter uses two adjustable weirs,
presumedly to proportion flow between aeration basins # 1 and #2. Provide an
engineering basis for why adjustable weirs are preferable over fixed weirs for.this
application. We:assume:thatwhen-both-basins are used.simultaneously, a 50/50
split would always be desired, which -could be -accomplished --effectively with fixed
weirs. Shut-off valves on pipes following the overflow from each weir could
serve to shut down either basin for maintenance, etc.
(b) What is the recycle rate from the aerobic zone of the oxidation ditch back to the
first anoxic zone? What is the variation in recycle rate provided by the flow
control gate?
(c) It is unclear from the design calculations provided how the MLSS concentration
in the oxidation ditch of 4,000 mg/l was arrived at. Please clarify. Discuss the
MLSS range necessary for effluent compliance purposes.
(d) We note that the plans call for a 15-foot fixed weir and a 15-foot adjustable weir
on each carrousel aerobic basin feeding into the second anoxic basin. Confirm
that the adjustable range of the weir will have the desired variation of water level
in the aerobic basin for proper aerator performance.
(e) Is it necessary to provide an additional carbon source into the second anoxic basin
for enhanced denitrification purposes in this basin? Please elaborate.
(f) Is it necessary to provide supplemental alkalinity based on influent alkalinity and
alkalinity destroyed/gained in the nitrification/denitrification process? Please
elaborate.
(g) When would the future methanol feed be used for the effluent filters?
8. We note that the proposed reaeration basin incorporates a flow splitting fixed weir for
effluent flow discharged to the Neuse River and an adjustable weir for effluent flow sent
to the quarry (water re -use). The Martin -Marietta quarry project incorporates a separate
effluent pump station for pumping the effluent to the quarry (about 1.5 miles away) via a
2

24-inch force main. General Comment #6 (above) addressed to potential need of a
discharge pipeline/diffuser into the Neuse River, with the probable requirement of an
effluent pump station also. We suggest that the Engineer consider combining these two
effluent pumping requirements into one pump station by moving the proposed quarry
effluent pump station into a common wall/wetwell pump station with the proposed
Reaeration Basin. A single weir (with baffles to reduce wave action in the Reaeration
Basin) could send flow into the common wetwell. Since the pumping requirements for
the quarry force main and the Neuse River force main would be different, the two
different types of pumps could be placed in the common wetwell. This suggested design
change may reduce the overall construction costs for effluent pumping for both projects.
We recommend this design change even though the city may opt not to add .the river
discharge pipe into-theprojectjat.this time:With -this _design_change-the.-city_couldlater
add the Aischarge-pipe =without..having:to:redesign-the effluentpumping=station. �We note
that this design change would require altering the Plans and Specifications for the
Quarry project.
9. Regarding the bid form and specifications for the proposed lime pasteurization process,
for the purposes of producing a competitive bid, we recommend that the bid form contain
an evaluated cost factor worksheet which calculates the present worth for 20 years of
operating the Class A biosolids system. In this manner, a fair formula is established by
which different lime pasteurization systems supplied by different contractors/suppliers
can be compared and bid. We recommend contacting RDP _Technologies, Inc. -regarding
this proposed bidding strategy.
10. Regarding the proposed lime pasteurization process for producing Class A biosolids, we
have the following comments/questions: (Note: The additional information from the
responses to this comment should be incorporated into the WWTP Residuals
Management Plan.)
(a) Specify how the 40 CFR 503 Vector Attraction requirement for Class A biosolids
will be met.
(b) Is it anticipated that the generated Class A biosolids will obtain the "exceptional
quality" rating (according to 40 CFR 503), as in the case of the Lenoir, NC
biosolids program? If so, provide documentation demonstrating that the WWTP
sludge passes the Part 503 pollutant concentration limits.
(c) Discuss the complete operational cycle of the sludge wasting and sludge
processing system. Include in this discussion the following:
(i) Wasting sludge to the Aerated Sludge Holding Tanks (ASHT),
(ii) Procedures and ASHT sequencing for sludge thickening, decanting, and
withdrawing thickened sludge, to include the estimated time required to
3

thicken the sludge from 0.8% to 1.5%,
(iii) Detentions time in the ASHT's,
(iv) Operation of the Belt Filter Press,
(v) Operation of the lime pasteurization system,
(vi) Blending the pasteurized Class A biosolids with other additives, and
(vii) Storing and final distribution of the blended biosolids mix, with estimated
totalized biosolids volume, length of time of storage, and total storage
available.
(d) Regarding the Belt Filter Press calculations:
(i) We note that at WWTP design flow the press will be required to work
continually for two (2) 8-hour-shifts for a 5 day work week (almost 16
hours/day). We.recommend_thatthe City of.New.:Bern.consider
purchasing a second press �in order to reduce this long work load _on this
single -press. (Note:. Does the WWTP already own a BFP? We thought
we observed one on recent visit to the plant.)
(ii) Assuming the BFP feed pump rate is at the maximum of 160 GPM, this
gives 9600 gallons/hour of 1.5% solids, or about 1200 dry pounds/hour
feeding into the BFP. According to Section 11360 of the Specifications,
the BFP has a specification of 600 dry pounds/hour throughput. Thus, it
appears that the BFP feed pump will be required to operate at a rate of
about 80 GPM.
(e) Regarding the Lime Stabilization calculations, we note that at WWTP design flow
the Lime Stabilization Vessel will be required to treat approximately 92,200
pounds/week of 18% biosolids (coming from the Belt Filter Press). Assuming a 5
day work week for this piece of equipment, this implies treating 18,400
pounds/day. Section 11010 of the Specifications calls for the vessel to be capable
of treating 0.46 tons/hour = 920 pounds/hour of 18% biosolids. At this rate, the
vessel will be required to work18,400/920 = 20 hours/day for a 5 day work week.
This appears to be an excessive work load for this vessel.
(f) From the above comments (d) and (e), it appears that the BFP will not be able to
feed the Lime Stabilization Vessel near its maximum throughput rate.
Furthremore, if the Lime Stabilization Vessel is down for maintenance, but the
BFP continues to operate and biosolids stored temporarily, how can biosolids be
loaded back onto the Screw Conveyors for feeding into the Vessel?
(g) Discuss the proposed operational procedures to be followed when biosolids
monitoring demonstrates that the lime pasteurization system does not produce
Class A biosolids. (See EPA 625/R-92/013, page 34.) Give consideration to the
following options:
4

(i) Recirculating the Class B biosolids through the lime pasteurization system
a second time.
(ii) Distributing the biosolids as Class B onto the already permitted farms. In
this option, it is necessary to continually retain the existing land
application of sludge permit.
We recommend that the land application of sludge permit be maintained as a
back-up disposal method.
(h) Consider to possibility of the belt filter press and/or the lime stabilization system
being out of service for an extended period of time, such that it is necessary to
produce..Class B biosolids because of limited WAS storage volume. Demonstrate
with_calculations-that -the:aerobic_digesters-and/or-other_processes available could
.effectively produce -Class _B_sludge -on a continual basis if required to do.so.
(i) Discuss the proposed operational procedures to be followed when the WWTP
operator -suspects that Class B biosolids were inadvertently distributed as Class A
biosolids. (See EPA 625/R-92/013, page 34.)
(j) Regarding the proposed Odor Control System to be used at the Sludge
Stabilization Facility, we have the following comments/questions:
(i) What is the anticipated chemical .constituents of the air to be scrubbed?
What is the anticipated chemical concentrations of these constituents in
wash water after scrubbing? What additional chemical loading will this
have on the WWTP as this water is sent via the plant drain back to the
head of the WWTP?
(iii) Document that the proposed air scrubber will be effective in correcting any
odor problems. Is it necessary to include a chemical feed into the water to
be used for air scrubbing, in order to more effectively remove these
chemical constituents from the air?
(iv) Odor Collection Hoods are to be located at the front end of the Lime
Pasteurization Vessel (Sheet 75) and at the tail end of the Biosolids
Discharge Conveyor (Sheet. 76). Are these the optimum locations for the
Odor Collection Hoods, and are there other places where Odor Collection
Hoods should be located?
(v) We encourage you to discuss odor control issues with the Charlotte
Mecklenburg Utility Department (CMUD) WWTP personnel (or call their
Engineer, Bob Forbes of CH2M Hill). The CMUD WWTP has a lime
5

stabilization of sludge process, and they have experienced odor problems
in the past.
Comments on Plans:
1. Sheet 6
Referring to the existing sludge drying beds:
(a) The reference to Detail 1 on Sheet 58 should be Detail 1 on Sheet 57.
(b) Fill in the Note that says "Plug Existing Pipes (Typ), See ".
2. Sheet 9
Between the proposed two clarifiers are overlapping words associated with the proposed
flow splitter.
3. Sheets 11 and 12
(a) Indicate the pipe size (diameter) of the scum pipes coming out of the secondary
clarifiers, and indicate where the 4" scum lines increase to 6" lines. (See
comment #4 below also.)
(b) It is not clear where the plant drain feeds to. Please clarify.
(c) We note that the effluent filter backwash (8-inch) line connects to the 20-inch
RAS line, which routes the filter backwash water to the head of the oxidation
ditch along with the RAS. We recommend adding piping and valving which also
allows the WWTP operator the option of routing the backwash water to the sludge
digesters. This can easily be accomplished by connecting the 8-inch backwash
line to both the 20-inch RAS line and the 6-inch WAS line via an "H" pipe and
valve arrangement. In this manner, if the WWTP operator notices that the
effluent filter is requiring more frequent backwashing because of build-up of
recalcitrint floc not settling out in the clarifiers, the operator may route the filter
backwash to the digesters to remove this "burned up unsetteable floc" from the
liquid train of the WWTP.
4. Sheets 14
Indicate where the 4" to 6" reducer is on scum pipe in Alignment No. 4.
5. Sheet 16
(a) Indicate the invert elevation of the 24" pipe through the existing walls in Section
A.
C1

(b) Indicate whether the water line used for pump seal water is potable water or non -
potable water. If potable water, then provide documentation that proper backflow
preventers have been used. If non -potable water, then provide documentation
where this water line comes from.
6. Sheet 18
We note that according to the Aerated Degritter Section of the Design Notes and
Computation Notebook, the Lakeside Aeroductor drawing shows the effluent weir to be
along the entire length of the basin (24 feet long), whereas Sheet 18 and subsequent
sheets shows the weir length to be 8 feet.
7. Sheet 21, Section D
(a) .-Indicate.-the-invert elevation .of -the .24"__DIP_pipe (coming--fromthe .Glenbumie _.
Pump Station) just prior to the 90 degree -bend.
(b) Indicate the invert elevation of the 36" DIP -effluent pipe (coming out of the
Preliminary Treatment Unit) just after the 90 degree bend.
8. Sheet 23
(a) Regarding the flow splitter boxes for the 36" influent pipe and the 20" RAS pipe,
it appears from Sheets 23 and 26 that the two splitter boxes are separate boxes,
whereas it appears from Sheets 11 and 13 that the two splitter boxes are combined
into one splitter box. Furthermore, inspection of Sheet.23 regarding the 36"
influent pipe splitter box (upper left corner of sheet) reveals that this splitter box
sends flow to the mirror image aeration basin # 1 only. It is assumed that the 36"
pipe influent flow and the 20" RAS pipe flow must be split evenly between
aeration basins # 1 and #2.
(b) Provide details regarding the flow control gate, to be installed in the oxidation
ditch aerobic zone near the effluent weir.
9. Sheet 32
It is not clear why dual adjustable weirs are used in the effluent flow splitter box. We
assume that when both secondary clarifiers are in operation, a 50150 split would always
be desired. This could effectively be accomplished using fixed weirs. Shutting down a
clarifiers could be accomplished using shut-off valves on the 30-inch pipe following each
weir.
10. Sheet 35
The Geotechnical Report indicates very soft clayey silts near the B-7 boring area (under
proposed Clarifiers No. 2), and the report recommends stabilization or separator fabric be
included in the clarifiers foundation design in order to prevent migration of stones into
the very soft silts. There should be indication of this in the Plans.
7

11. Sheet 40
(a) There are two cross section cutlines shown labeled H/Sheet 26, with one for the
mudwell pumps, and another (labeled similar) for the backwash pumps in the
clearwell. The cross section through the backwash pumps does not appear to be
similar to H/Sheet 26 (see Section C on Sheet 45).
(b) What does the detail X on Sheet Y refer to (floor and wall sleeve)?
(c) The detail E on Sheet 47 does not appear to represent the cross section labeled
E/Sheet 47 (referring to the staircase near the blowers).
(d) The discharge pipe for the sump pump in Cross Section G on Sheet 45 appears to
discharge -back _to_a_drain.pipe _that_drains back to _the sump --pump _(see Cross
Section B_on Sheet 43).
(e) The sump pump which drains the sump pit (an sunken area about 60' by 30') has a
design pumping rate of 12 gpm, according to Section 11306 of the Specifications.
Consider providing a larger capacity sump pump for situations when intense
rainstorms flood the sump pit area.
12. Sheet 46
The drain pipes from the two sump pumps should not allow drain water to spill onto the
ground, but rather the drain water should be routed back to the clear well, etc., for
collection.
13. Sheet 48
There are several details that are not referenced correctly (Detail Z on Sheet 44, and other
detail references that are blank).
14. Sheet 49
There are several details that are not referenced correctly (Detail A on Sheet 44, and
Detail Z on Sheet 82).
15. Sheets 50-51
We suggest combining the Quarry projects' effluent pump station with the pump station
to be required by the Neuse River discharge pipe. This will probably require a re -design
of the two effluent weir boxes at the end of the reaeration basin. See General Comment
#8 above.
16. Sheet 51
The note associated with the influent pipe (on the left-hand side of the sheet) has some
unreadable words.
8

17. Sheet 56
(a) This sheet shows that the belt filter press (BFP) feed pumps send the thickened
sludge via a 4-inch pipe to the BFP in the Waste Stabilization Facility, whereas
the Design Notes and Computations Notebook uses a 6-inch line for pipe friction
loss calculations. Sheet 12 has this line as a 4-inch pipe, whereas Sheet 14 on
Alignment No.7 list this as a 6-inch pipe. Please clarify.
(b) It appears that WAS must enter Aerated Sludge Holding Tank (ASHT) No. 1
and/or No. 2 first, then be transferred to ASHT No. 3, then be pumped by the BFP
feed pumps to the BFP. in the Waste Stabilization Facility. Is this correct? If so,
consider adding the flexibility of allowing the WAS to be sent to. either of the
three ASHT's, and allowing any three ASHT's to discharge to the BFP feed
PUMPs-
18. Sheet 58
There are several notes that read " ... See Note X on .Sheet 56" which should read " ....
See Note X on Sheet 57".
19. Sheets 60 - 62
The reference to Section A on Sheet 63 should read Section A on Sheet 64.
20. Sheet 60
(a) In the middle of the Sheet, fill in the Note with the blank: "4" Drain at % from
Scrubber".
(b) Estimate the quantity of water the sump pump may have to remove over a
specified period of time to ensure that a 12 GPM pump capacity is sufficient, such
that the drains don't back up.
21. Sheet 61
(a) Discuss the purpose of Screw Conveyor No. 5, and the location of the discharge
point.
(b) Regarding the Detail A entitled "Walkway Section" (lower left corner), the
references to details on Sheet 42 appear to be wrong.
(c) Label Screw Conveyor No. 1 feeding off the Lime Storage Silo.
(d) Referring to the Chemical Feed Vault:
(i) The reference to the detail for the Chemical Feed Vault needs to be filled
in (bottom of Sheet), and it appears that this vault detail is missing.
(ii) Discuss the rationale for not locating the Chemical Feed Vault inside the
Sludge Stabilization Facility next to the Belt Filter Press.

(e) Show the connection of the 3-inch drain coming out of the Odor Control System
Scrubber Tower to the underlying 4-inch drain pipe (as seen on Sheet 60).
(f) The following cross sections appear to be labeled wrong:
(i) Cross section "1 on Sheet 70" (along Screw Conveyor No. 1) should be
labeled "1 on Sheet 69"
(ii) Cross section labeled "2 on Sheet 70" (along the Dolomitic Lime Bins)
should be labeled "2 on Sheet 69"
(iii) Cross section labeled "1 on Sheet 71" (along Screw Conveyor No. 3)
should be labeled "1 on Sheet 70"
(iv) Cross section labeled "2 on Sheet 71" (along Screw Conveyor No. 2)
should be labeled "2 on Sheet 70"
(v) Cross section -labeled "1 _on_Sheet .73 "_ (along:the Thermoblender) _should
belabeled `I _on Sheet 72".
(vi) Cross section labeled "1 on Sheet 76" (along the Lime Pasteurization
Vessel) should be labeled "l on Sheet 75"
(vii) Cross section labeled "1 on Sheet 74" (along the Lime Transfer Screw
Conveyor) should be labeled "1 on Sheet 73"
(viii) Cross section labeled "l on Sheet 77" (along the Biosolids Discharge
Conveyor) should be labeled "1 on Sheet 76".
22. Sheet 62
Cross section "A on Sheet 63" should be labeled "A on Sheet 64"
23. Sheet 64
(a) In the lower left corner, the following note references the wrong sheet: "See
Foundations Plans and Details: See Sheet 64".
(b) Fill in the reference for the note on the left side of the belt filter press which says
"Mounting Bracket for Hose Reel: See Detail _ on Sheet _".
24. Sheet 70
Referring to Section 1 (top of Sheet), it appears that the Note regarding the conveyor
support should reference detail 3 on Sheet 70, not Sheet 69.
25. Sheet 71
Referring to the connection between Screw Conveyor No. 4 and No. 5 as shown on
Section 1 (top of Sheet):

Construction Grants & Loans Policy
Regarding
N.C.G.S.133-3
The Construction Grants Loans policy requires specifications to be written in a manner that
maximizes competition. It has been our experience that performance specifications are often
written in a restrictive manner. Therefore, our office expects the engineer to identify three
manufacturers that can meet the performance requirements in a letter to our office. When three
cannot be identified then as many as are known should be- identified. Our review of plans and
specifications could be expedited if the specifications clearly identified three manufacturers who
can comply with the proposed specification. Doing so also promotes a free flow of information
and _enhances ..competition.
In the -event -that there is only one acceptable. manufacturer; we expect the engineer to justify why
the specification must be sole source. The justification should be supported with the.following
type of information:
1. Cost Effectiveness: Capital cost, O & M, Replacement cost, Energy (HP $), Patent
fees, Royalties, other.
2. Total construction time.
3. Performance history.
4. Reliability over life of the project; availability of parts and service, etc.
5. Pilot Studies on a case by case basis.
Upon our concurrence with the engineer's findings, the owner and engineer would be expected to
document negotiations with the manufacturer. A copy of the memorandum of negotiations
should be provided and a 5700-41 form must be completed by the manufacturer. The
specifications would then identify where the product is to be obtained and state the amount that
the contractor must pay the manufacturer.
There are times when an owner or engineer has a preference for a specific manufacture. State
law allows you to establish a base bid and identify the preferred product as an alternative bid
item. This allows the owner to award the contract to the lowest of the base bid or the lowest of
the alternative bids even if the alternative bid is more expensive than the base bid. Typically our
participation will be limited to the least cost of all alternatives. When concrete and electrical
work are significantly different between the base bid and the alternate bid, then the designs of
both should be shown on the plans. Otherwise, while it is preferable to show the base bid item
on the plan, it is acceptable to only show the alternate bid item on the plans.

3. Important SOC, JOC, or Compliance Schedule dates (indicate): The City will be unable to meet
effluent limits during the construction of the new ww treatment plant. I have advised Mr. David Muse
to apply for an SOC modification.
PART IV - EVALUATION AND RECOMMENDATIONS:
The expansion of this wastewater treatment plant from 4.7 MGD to 6.5 MGD should include a new
discharge line with a diffuser. The effluent discharge limits are based on a dilution not presently achieved
with the existing bank discharge. The Construction Grants and Loans Section is presently reviewing an
Authorization to Construct (AtoC) application to build the new 6.5 MGD treatment works. This
application does not include a discharge line and diffuser. One regional comment to the AtoC request was a
recommendation that a discharge line and diffuser was needed at this site. In the event the City is unable to
construct a new discharge line during the proposed expansion, a schedule by which the new discharge line
may be added should be request and included as a condition in the permit. The schedule should be no longer
than the life of the new permit.
It is assumed the speculative limits in the letter from Dave A. Goodrich's dated June 8, 1998 to Walter
Hartman, Jr. City Manager of New Bern is still valid? If these limits have changed please notify the Region
so that additional comments may be presented.
It is recommended the application to modify NCO025348 be granted with the condition a new discharge line
with a diffuser is part of the proposal and the June 8, 1998 speculative limits are still valid.

MU DEFINITIONS
The following definitions shall apply throughout this Subchapter.
(1) Activated Carbon Beds. A physical/chemical method for reducing soluble organic material from wastewater effluent; The column -type beds used In this
method will have a flow rate varying from two to eight gallons per minute per square foot and may be either upflow or downflow carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant site;
(2) Aerated Lagoons. A basin In which all solids are maintained in suspension and by which biological oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about intimate contact between air or high purity oxygen in a liquid by spraying, agitation or di fusfon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4) Agricuhurally managed site. Any site on which a crop Is produced. managed. and harvested (Crop Includes grasses. grains. tress, etc.);
(5) Air Stripping. A process by which the ammonium Ion is first converted to dissolved ammonia (pH adjustment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene. toluene, and xylene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed Impurities;
(7) Carbonamous Stage. A stage of wastewater treatment designed to achieve 'secondary' effluent limits;
(8) Centrifuge. A mechanical device In which centrifugal force Is used to separate solids from liquids or to separate liquids of different denshilas;
(9) Chemical Addition Systems- The addition of chemicals) to wastewater at an application point for purposes of Improving solids removal. pH adjustment.
alkalinity control, etc.; the capability to experiment with different chemicals and different application points to achieve a specific. result will be considered one
system; the capability to add chemicals) to dual units will be rated as one system; capability to add a chemical at a different application points for different
purposes will result In the systems being rated as separate systems;
(10) Chemical Sludge Conditioning. The addition of a chemical compound such as time, ferric chloride. or a polymer to wet sludge to coalesce the mass prior to
its application to a dewatering device;
(11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing inorganic. non -toxic materials from sand, gravel,
crushed stone or other similar operations. Such systems shall cant' a maximum of two points regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous BOD and Nitrogenous Removal by Nitrification- A single stage system required to achieve permit effluent limits on BOD
and ammonia nitrogen within the same biological reactor,
(13) Dechlorination. The partial or complete reduction of residual chlorin* in a liquid by any chemical or physical process;
(14) Derthrification Process. The conversion of nitrate -nitrogen to nitrogen gas;

Memorandum
To: Mike Templeton
From: Christie Jackson
Date: 04 / 04 / 00
Re: New Bern (NC0025348)
I did not enter RPA Data for Cadmium, Lead, Mercury and
Chromium as they all had < values recorded on the DMR's.
The.: self- monitoring summary report indicated that this
facility :FAILED the toxicity tests in December 1996, June
19 37,.. March 1998, September 1998, December 1998 and
March 1999. You may want to review the DMR's for
additional information on Zinc, Silver and Copper.

City of New Bem (NPDES Number NC0025348)
Craven County
Dear Mr. Muse:
In a February 7, 2000, letter from the Pretreatment Unit of the Division of Water Quality reviewing the
Headworks Analysis (HWA) for the City of New Bern, we included various draft HWAs addressing the
potential relocation of o the W WTP discharge point to a quarry. Those draft HWAs applied North Carolina
Water Quality Standards for freshwater and saltwater water quality standards that apply to surface waters. It
has come to our attention that North Carolina Water Quality Standards that apply to groundwater may be
applied instead. See the Comprehensive Guidance for North Carolina Pretreatment Programs, Chapter 5,
Appendix 54. Attached please find a draft HWA and AT using NC groundwater standards and a 7Q10 of zero
(worst case scenario). As discussed in our February 7, 2000, letter, please keep us appraised of the status of
your plans as they relate to your Pretreatment Program, especially your LTMP and HWA.
You are reminded that your updated HWA is due September 15, 2003, unless conditions change. Please note
our new mailing address and fax number at the bottom of each page of this letter. Thank you for your
continued cooperation with the pretreatment program. If you have any questions or comments, please contact
me at [phone] (ext. 523), or Tom S. Poe (ext. 522), Supervisor of the Pretreatment Unit.
Sincerely,
`n`L

Charles,
I haven't been able to locate any records of us (my unit) having completed
an EA for New Bern for any expansion. But, I believe CG&Ls recently
completed an EA for an expansion. Through this e-mail I am asking Reggie
if he can let us know if the FONSI has been written and the Clearinghouse
review has been completed.
Reggie,
Would you reply to both of this on Charles' question below. Thanks.

Yes, the FNSI/EA process has been completed for the expansion of the New
Bern treatment plant from 4.7 to 6.5 mgd.
Do you need the Clearinghouse approval letter and/or the FNSI/EA?

Enclosed are three (3) executed copies of the NPDES Discharge Permit application for
the New Bern WWTP expansion and a $400.00 processing fee (Rivers Check No.
58598).
The City of New Bern requests an increase in the permitted flow rate from 4.7 MGD to
6.5 MGD in accordance with the attached speculative discharge limits.
Plans and specifications have been prepared for the planned expansion, and are
currently being reviewed by State Construction Grants & Loans. A copy of these
documents has probably been forwarded for your review by CIS & L.
Should you have any questions regarding this project, please do not hesitate to call.

RE: Permit Renewal Application - NPDES Permit No. NCO025348
Dear Mr. Weaver,
Please accept this document as a request for renewal of the NPDES Permit No. NCO025348 for
the City of New Bern Municipal Wastewater Treatment Plant. Enclosed you will find one original
and two copies of the application.
The only change made to the plant since the last permit renewal concerns the digester supernate
drain. In 1997, the drain was rerouted from the original disposal to the distribution box located
subsequent to the head works to a point preceding the head works. The drain was moved to
discharge to the Glenburnie Lift Station wet well immediately adjacent to the digesters and
headworks. This change allows the headworks ananlysis to reflect the supernate loading on the
plant and eliminated a poor design flaw.
If you have any questions, do not hesitate to contact me.
Sincerely,
�
Walter B. Hart

City of New Bern Wastewater Treatment Plant
The wastewater treatment
was originally constructed in
1964. It was a single train
trickling filter plant, capable of
treating a flow of 4.0 MGD. In
1991 a second treatment train was
added. The expanded plant is able
to adequately treat an average
flow of 4.7 MGD and peak flows
of 12 MGD.
The raw wastewater enters
the treatment plant at the
headworks. The influent structure
contains the screening mechanism,
the grit removal system and the
chemical feed. The screen
removes large solids, such as
paper, cans, and rags. The aerated
grit removal system eliminates
sand and grit from the wastewater.
These processes minimizes wear
and tear on pumps and keeps sand
from accumulating in process
structures. A metallic salt, sodium
aluminate is added to precipitate
the phosphorus.
The flow leaves the
headworks and is distributed
between two primary clarifiers.
Primary settling removes
approximately 60 % of the heavy
organic material and settleable
solids. The sludge also contains
the phosphorus that settled as a
result of the chemical
flocculation. The settling material
is collected and pumped to a
sludge thickener. A skimmer
removes the floating grease from
the tank.
The liquid portion of the
wastewater flows to the trickling
filters. The trickling filter is a
biological treatment which is used
to convert non -settleable colloidal
and dissolved solids to settleable
solids. Wastewater is sprayed
over rock media. On the surface
of the rock live microorganisms
which consume the organic
material. Aerobic in nature they
utilize the air in the rock voids.
The flow then passes through
recirculation pumps where part of
the flow is diverted back to the
filters to help regulate flow rates
from the distribution arms.
The excess flow from the
recirculating pump station travels
through the final settling tanks
designed to collect solids from the
biological treatment process.
These solids are pumped back to
the distribution box. After settling
a second time, the solids are
pumped to the primary digesters.
The waster water is
discharged to a flash mixer where
chlorine is added for disinfection.
This provides the destruction of
pathogens before it is discharged
to the Neuse River. To reduce
toxicity of the chlorine on the
receiving stream, sodium bisulfite
is added.
Sludge Handling
The sludge collected from
the primary settling tanks is
pum'ped to the sludge thickeners
to remove excess water.
Thickened sludge is pumped to
two primary digesters. In the
primary digesters, anaerobic
bacteria change organic material
into inorganic nutrients. Methane
gas is a by product of the
digestion. The methane in used to
heat the primary digesters to 95
degrees, the temperature at which
digestion takes place. The
digestion of sludge further reduces
pathogens and removes much of
the volatile solids.
The digested sludge is then
applied to agricultural land. It
makes a good soil builder and an
inexpensive fertilizer. There are
27 sand drying beds available for
use if sludge cannot be applied to
land due to weather conditions.
Laboratory Testing
Inside the operations
building is the wastewater
laboratory. Testing is done on
both the influent and effluent for
plant efficiency and monitoring
process. The sludge is also
monitored for nutrient content and
metal toxicity.
