Subject: NPDES Permit Issuance
Permit No. NCO023965
James A. Loughlin Plant
New Hanover County
In accordance with the application for. discharge permit received on December 29,
1995, the Division is forwarding herewith the.subject state - 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 December 6, 1983. '
In response to your comments, the Division has made the following changes to the
DRAFT permit:
a) The aeration basin has been described as 0.85 MG as opposed to 0.85 MGD
on the .Supplement to Cover Sheet.
b) The instream monitoring frequency for temperature has been changed to
weekly.
c) The Acute Toxicity test organism has been changed to Daphnia Pulex.
d) The mercury sample type has been changed to grab.
The permittee has the option of contracting with the Cape Fear River Program to
perform the instream monitoring regime. Cyanide has been documented at high levels; .
therefore,, it is the Division's intent to gather additional data on this toxicant and leave the
permit requirement unchanged at this time.
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 redeipt 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, Post Office Drawer 27447,
Raleigh, North Carolina 27611-7447. Unless such a demand is made, this permit shall be
final and binding.

G. ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
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." The monitoring shall be performed as a Daphnia
Pulex 24 hour static test, using effluent collected as a 24 hour composite. The effluent
concentration at which there may be at no time significant acute mortality is 90% (defined as
treatment two in the North Carolina procedure document). Effluent samples for self -monitoring
purposes must be obtained during representative effluent discharge below all waste treatment. The
first test will be performed after thirty days from the effective date of this permit during the
months of February, May, August and November.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using.:the parameter
code TGE6C. Additionally, DEM Form AT-2 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
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 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 any test data from either these monitoringrequirements or tests performed by the North
Carolina Division of Environmental Management 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 retesting (within 30 days of initial monitoring event), Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

Permit No. NC0023965
F. The effluent discharge shall at no time exhibit chronic toxicity in anytwo consecutive toxicity
tests, using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluentbioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *June 1988) or subsequent versions.
The effluent concentration at which there may be no observable, inhibition of reproduction or
significant mortality is 1.7% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from issuance of this
permit during the months of February, May, August, and November. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
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 TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention:

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 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 any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be reopened 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 retesting (within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute.;:rioncompliance:with monitoring requirements.
G. The permittee shall conduct a test for pollutants annually at the. effluent from the treatment
plant. The discharge shall. be evaluated as follows: 1) A pollutant analysis of the effluent must be
completed annually using EPA approved methods for the following analytic fractions: (a)
purgeables (i.e., volatile organic compounds); (b) acid extractables; (c) base/neutral extractables;
(d) organochlorine pesticides and PCB's (e) herbicides; and (f) metals and other inorganics. The
Annual Pollutant Analysis Monitoring (APAM) Requirement Reporting Form A and
accompanying memo, to be provided to all discharges affected by this monitoring requirement,

describes the sampling and analysis requirements and lists chemicals to be included in. the
pollutant analysis. This monitoring requirement is to be referred to as the "Annual Pollutant
Analysis Monitoring Requirement"' (APAM).
2) Other significant levels of organic chemicals must be identified and approximately quantified.
For the purpose of implementing this requirement, the largest 10 GC/MS peaks in the purgeable,
base/neutral extractable, and acid extractable fractions (or fewer than 10, if less than 10
unidentified peaks occur) for chemicals other than those specified on the APA Requirement
Reporting Form A should be identified and approximately quantified as stated in the APAM
Reporting Form 'A instructions. This part (item 2) of the APAM requirement is to be referred to as
the "10 significant peaks rule".

rn
Since- this is a renewal at the existing flow, no changes are rmotramended for conventional pollutant
limits at this time. Based on evaluation of effluent data, some changes are recommended in regla?d
to monitoring for toxicant parameters, WET test should be changed to a an acute test to reflect the
tidal nature of the receiving stream and to achieve consistency with the tests for other dischargers in
this area. Due to the difficulty in determining the degree of mixing and appropriate dilution for this
discharge, prior to the next renewal or any upgrad%xpansion of the plant, the City should conduct
a study in conjunction wit: DEM to support the necessary modeling to determine the diffusion
pattern and degree of dilution. In, this renewal. the expectation to do such a study should be
established with the perzzzittee�with the understanding that the resulting appropriate toxicant limits
will then be assigned as dammed necessary. Addition of instream monitoring is also recommended
for this renewal. Please see Special Instructions or Conditions section.

ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The permittee shall conduct acute toxicity tests on a q=rterl
y basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent
Concentration." The monitoring shall be performed as a Fathead Minnow 0meT o�melas) 24 hour static
test, using effluent collected as a 24 hour composite. The effluent concentration at which there may be at no time
significant acute mortality is 90% (defined as treatment two in the North Carolina procedure document). Effluent
samples for self -monitoring purposes must be obtained during representative effluent discharge below all waste
treatment. The first test will be performed after thirty days from the effective date of this permit during the
months of av .. , e ✓.
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, DEM Form AT-2 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
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 dosetresponse 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 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 any test data from either these monitoring requirements or tests performed by the North Carolina Division
of Environmental Management 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
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

observations greater than the criterion; N/S=No sample; N/C=No Criteria; AL --Action Level
Notes: Median values are calculated using the detection level for samples classified as below detection. The Median value for
Fecal Coliform is actually the Geometric Mean value. Data includes only surface samples. Samples recorded at less than
detection are considered at the detection level for this summary.

MEMORANDUM ,

THROUGH:
Ruth Swanek
Carla Sanderson i
FROM:
Jason C. Doll
SUBJECT:
Whole Effluent Toxicity Tests
Test Assignment Protocols
Lower Cape Fear River Basin
As I have discussed in recent phone conversations with you, we have had problems in
the past with inconsistency in the assignment of WET tests in the lower Cape Fear River.
The area of concern begins in the Cape Fear at Lock and Dam #1 and in the Northeast Cape
Fear at the Occidental Chemicals discharge. The inconsistencies have in turn caused
discrepancies in toxicity test requirements/limits for the various facilities up and down the
river in this area, where tidal influences significantly affect the flow of river. The attached
table, arranged in upstream to downstream order, shows the WET test assignments for the
major dischargers in the area in question. Good examples of inconsistency are the WET
tests for the two City of Wilmington WWTPs. The two treatment plants discharge in a part
of the river where the hydrology is basically the same and the tests are chronic for one, and
acute for the other. Such discrepancies have caused difficulty for the Division in
administering and enforcing NPDES permits. The Cape Fear River Basinwide
Management Plan is currently being drafted, so it presents a good avenue to resolve this
issue by developing clear criteria for the assignment of WET tests in this area in the future.
With regard to the issue of saltwater vs. fresh water, current SOP for the modeling
group says, "Where a facility. with a high concentration of chlorides discharges to a tidal
saltwater, the test species may be switched to a saltwater species such as mysid shrimp."
The SOP goes on to caution, "Final determination of test requirements under these special
circumstances should be made after consultation with appropriate staff of the
Environmental Sciences Branch." These guidelines should continue to be followed, since
there are no evident inconsistencies in the current toxicity test requirements in terms of the
species. assigned.
The issue of tidal flushing vs. advective stream flow is a little more difficult to resolve,
and is the source of the inconsistencies in question. As you move downstream on the
enclosed table you can see that some facilities were given chronic tests based on an IWC
derived from estimates of advective flow, while facilities upstream of them received acute
tests on the basis of tidal flushing and mixing. DEM needs to determine a boundary at
which the flow in the river becomes dominated by tidal influences, and the advective flow
from upstream becomes "insignificant", or vice versa. The definition of what is considered
significant must also be resolved.

In 1985, USGS released a study of flow in the estuarine portion'of the river in a report
entitled "Hydrology of Major Estuaries and Sounds in North Carolina" (USGS Water -
Supply Paper #2221). The study was largely based on staff gauge data collected from
1966 - 1969 at a few stations in the lower Cape Fear and Northeast Cape Fear Rivers. The
study does designate upstream limits of tidal influence, at Lock and Dam #1 for the Cape
Fear and. near the mouth of Holly Shelter Creek for the Northeast Cape Fear, but it does not
quantify the frequency or magnitude of the tidal impact at these locations. The study gives
quantified assessments of tidal flow only at the flow gauges at Phoenix, 13 miles upstream
from downtown Wilmington on the. Cape Fear, and at the General Electric plant on the
Northeast Cape Fear, 6.4 miles above the mouth. In order to define a border to divide tidal
and non -tidal areas, more specific information regarding the magnitude of tidal influence
along river increments will be needed. We may be able to obtain such information from
USGS. If the information cannot be obtained from USGS, I would recommend that ESB
conduct dye studies on the lower Cape Fear in order to make a better determination of
where the dividing line should be.
Meanwhile, we can act on what we already know. As you come downstream on the
enclosed table of toxicity tests, note that the tests switch back to chronic, beginning with
the GE discharge. WET tests for GE, Arcadian and Wilmington Northside should be
changed to acute (24 hr., NSM @ 90%). This change would reflect the tidal nature of the
stream at their discharge locations already documented by USGS. All three of these
discharges are downstream of staff gauge sites that have clearly shown tidal flows. The
change would also make the permit requirements more consistent with the facilities
immediately upstream and downstream. It should be noted that this change is already in the
draft permit for GE, currently at public notice. The recommendation to change the
remaining two of these should be reflected in the basin plan, and carried out upon their next
permit renewal.
I would also recommend that Archer Daniels Midland receive an acute WET test with a
pass/fail limit in the next renewal, rather than the toxicity monitoring requirement in their
current permit. The facility is permitted to discharge 3.5 MGD of process wastewater with
several constituents having the potential to cause effluent toxicity. Monitoring by ADM
under the current requirement, a quarterly acute 24 hr. static test (full range), has shown the
discharge to exhibit intermittent toxicity, with one third of the tests over the last three years
resulting in LC50 values of >50 or less. Holding ADM to a standard of not causing acute
toxicity in receiving waters would be much more consistent with the requirements for other
facilities in this area.
Please call me if you have any questions or comments.

James G. Martin, Governor R. Paul Wilms
S. Thomas Rhodes, Secretary May 6, 1987 Director
Mr. John Bauer
Director of Public Utilities
P.O. Box 1810
Wilmington, NC 28402
Dear Mr. Bauer:
This letter is to confirm information that a member of my staff,
Trevor Clements, relayed to you by telephone. As you know, it is dif-
ficult to estimate an instream waste concentration (IWC) for facilities
in the lower Cape Fear Basin due to the effect of tides on water move-
ment. In your case, calculation of the IWC for the two Wilmington
facilities is further complicated by stream regulation in the upper
basin and by diversion of water in the lower basin via the Brunswick
River. The best method for estimating an IWC for your two facilities
would involve the use of fluorescent dye studies to measure tidally -
averaged dilution of the effluent in the receiving waters. You may
want to consider performing this type of study sometime in the future.
For your immediate need regarding the headworks analyses for the
Northside and Southside.plants, it is recommended that you use the
following information:
IWC = Qw x 100
7Q10 + Qw
where: Qw = Effluent Flow (cfs)
7Q10 = lowest 7 - consecutive day flow
w/ probability of occurring 1 in 10 years
IWC = Instream waste concentration (%)
Pollution Prevention PaYs
P.O. Box 27687, Raleigh, North Carolina 27611-7687 Telephone [phone]

For the Northside facility:
Qw = 8 MGD = 12.4 cfs
reg. 7Q10 z 1121 cfs @ Navassa
- 448 cfs diversion Brunswick River (assumed 40%)
+ 28 cfs NE Cape Fear River
-701 cfs
IWC = 12.4 x 100 = 1.7 percent
701 + 12.4
For the Southside facility:
Qw = 12 MGD = 18.6 cfs
reg. 7Q10 = 1121 cfs @ Navassa
+ 28 cfs NE Cape Fear River
1149 cfs
IWC = - 18.6 x 100 = 1.6 percent
1149 + 18.6
Therefore, our best estimates as to the IWC's for the Northside and
Southside Wilmington facilities are 1.7 and 1.6 percent, respectively.
ta+t�•-v+eti�v2
These estimates might be considered^since they do not account for tidal
mixing. However, they do include credit for all of the estimated freshwater
flow which is not conservative given the width of the river and the side -
stream location of each discharge. Therefore, these estimates should be
used with care'and with full acknowledgement of their uncertainty. DEM is
recommending them for use in your headworks analysis. At this point in
time, we are not recommending them for'use in determining whole -effluent
toxicity limits.
If you have any questions regarding this matter, please call either
Trevor Clements or myself (919/733-5083).
Sincerely,
Steve W. Tedder, Head

PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of wastewater to be permitted: 8.0 MGD
b. What is the current permitted flow limit? 8.0 MGD
C. Actual treatment capacity of the current facility:
8.0 MGD
d. Date and construction activities allowed by previous
Authorizations to Construct issued in the previous two
years: An A to C was issued 9/25/95 for the replacement
of each of 2 mechanically -cleaned bar screens.
e. Please provide a description of- existing wastewater
treatment facilities:- The existing facility consists of
influent flow meter, bar screen, a mechanically -cleaned
bar screen (soon to be installed), mechanical grit
removal, chemical feed for odor control, dual primary
clarifiers,` dual trickling filters, recirculation (to
primary clarifiers) pump station, intermediate pump
station to short-term activated sludge basin, dual
secondary clarifiers, flash mixing tank, chlorine contact
tank with gaseous chlorination, effluent flow meter, and'
an effluent pump station. Residuals: thickener, three
anaerobic digesters, and a belt press.
f. Please provide a description of proposed wastewater
treatment facilities: Future plans are to possibly
construct a parallel plant on -site or hydraulically -
expand the existing plant.
g. Possible toxic impacts to surface waters: Chlorine,
pretreatment program limits industrial toxicants.
h. Pretreatment Program: Approved, permitted SIUs:
Southern Graphics 0.002-MGD

PART III - OTHER
INFORMATION
Is this facility being constructed with Construction Grant
Funds or are any public monies involved? No
Special monitoring or limitations requests: None
Important SOC Schedule dates:
Effective Date: N/A
Submission of Plans and Specs: N/A
Begin Construction: N/A
Complete Construction: N/A
4. Alternative Analysis Evaluation:
Wilmington has the largest WWTP in the region. The plant is
located adjacent to the Cape Fear River and soils are marginal
and the depth to the groundwater table is not sufficient for
subsurface disposal or spray irrigation.
5. Other Special Items: Two outfalls are to be limited in the
permit. 001 is the former outfall which discharged into
Smith Creek. The City would like to retain this outfall in
case of pump failure to outfall 002, which is the existing
outfall into the Cape Fear River. The City has not used 001
in the past ten years, but limits should be listed to reflect
discharge to Smith Creek.
PART IV - EVALUATION AND
The Northside plant has operated over,the past year with no
effluent limit violations or chronic toxicity failures. The
City has indicated it will likely choose to perform its own
instream monitoring versus participating in the UNCW program.
It is recommended that a draft permit be prepared and placed
at public notice. If no significant adverse public comment is
received, it is recommended NPDES Permit No. NCO023965 be
reissued to the City of Wilmington in accordance with the
Cape Fear River basin -wide permitting strategy.

WASTEWATER TREATMENT FACILITY CLASSIFICATION
The following systems shall be assigned a Class I classification, unless the flow is of a significant quantity or the technology is unusually
complex, to require'consideration by the Commission on a case -by -case basis: (Check if Appropriate)
1. OiVwater Separator Systems consisting only of physical separation, pumps and disposal;
2. Septic Tank/Sand Filter Systems consisting only of septic tanks, dosing apparatus, pumps,sand filters, disinfection
and direct discharge;
3. Lagoon Systems consisting only of preliminary treatment, lagoons, pumps, disinfection, necessary chemical treatment -for
algae or nutrient control, and direct discharge;
4. Closed -loop Recycle Systems;
5. Groundwater Remediation Systems consisting only of oJUwater separators, pumps, air -stripping, carbon adsorption, disinfection
and diisposaJ;
6. Aquacufture operations with discharge to surface -Waters;
7. Water Plant sludge handling and back -wash water treatment;
8. Seafood processing consisting of screening and disposal.
9. Single-family discharging systems, with the exception cf Aerobic Trea:r::ent Units, will be classified if permitted after July 1,
1993 or if upon inspection by the Division, it is found that the system is not Ding adequately operated or maintained. Such
systems will be notified of the classification or reclassification by the Commission, in writing.

MU DEFINITIONS The following definitions shall apply throughout this Sdxhapter.
(1) Activated Carbon Beds. A physicallcembcal method for reducing soluble organic material from wastewater eMusrt; The r:a ;mn type beds used in this
method will have a flow rate varying from two to eight gallons per minute per square toot and may be ether upflow, or downflaw carbon beds. Carbon may or
may not be regenerated on the wastewater treatment pom she;
(2) Aerated Lagoons. A basin in which all soils are mainWned In suspension and by whirl bidogical oxidation or organic mazer is reduced through amcialfy
accelerated transfer of oxygen on a flow -through basis;
(3) Aeratlon A process of bringing about Intimate contact between air or high purity oxygen in a liquid by sprayk+g, agitation or tiffuslong3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of is hours.
(4) Agriculturally managed she. Any she on which a crop is produced, managed, and harvested (Crap ine#xdes grasses, grelra, Use, ewle
(5) Air Stripping. A process by which the ammonium ion Is first converted to dissolved ammonia (pH adFAmert) with the ammonia then released to the
atmosphere by physical means; or abet similar processes which remove petroleum products such as benzene, toluene, and xyiene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide exuemey high torriperattses which tree and oxidize the
absorbed impurities;
(n Carbonaceous Stage. A stage of wastewater treatment designed to achieve %ecax:W eltMte d &nft
(8) Centrifuge. A mechanical device In which centrifugal force Is used to separate solids from liquids or to separate Ii;ft of dMenwe dermas•
(9) Chemical Addition Systems- The addhion'of dlemicai(s) to wastewater at an appScaslort point for purposes of trpvvirg scuds remora!, pH adj rstmert,
alkalinity control, etc.; the capability to experiment with different chemicals and different application paints to achIM a specMe result will be considered one
system; the capability to add chemical(&) to dual units will be rated as one system; capability to add a oberrrioal at a cftrert application points for ddferent
purposes will result In the systems being rated as separre systems:
(10) Egcycle
Sludge Conditioning. The addition of a chemical compound such as Ime, ferric dhlodde, or a polymer to wet thr6gs to coalesce the man prior to
Rot apto a dewatering device;
(11) Systems. Use of holding ponds or haidng tarn s for eonWnmwd of wastewater eortakft ltwrgark- non -toxic matertss from sand, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping facilities or any other aPpurtenarres;
(12) Combined Removal of Carbonaceous BOD and Nit other Removal by Nitrification- A single stage system required to adhim permit ealuert fruits on BOD
and ammonia nitrogen within the same biological reactor,
(13) Dechlorinatton The partial or complete reduction of residual chlorin• in a Squid by any detrital or physical proetess;
(14) Denbrffieatlon Process. The conversion of nhrate-rArogen to nitrogen gas;
