Dear Mr. Reavis:
Jonathan B. Howes, Secretary.
Subject: NPDES Permit NC0024201
Roanoke Rapids Sanitary District
Halifax County
On January 29, 1993, the Division of Environmental Management issued NPDES Permit
No. NC0024201 to Roanoke Rapids Sanitary District. A review of the permit file has indicated
that an error was inadvertently made in the permit. Accordingly, we are forwarding herewith
modifications to the subject permit to correct the error. The modifications are as follows: Part III,
Condition J, has been modified to require that the outfall be relocated upon plant expansion or
upon permit renewal.
Please find enclosed the amended Special Conditions sheets which should be inserted
into your permit. The corresponding old sheets should be discarded. All other terms and
conditions contained in the original permit remain unchanged and in full effect. This permit
modification is issued pursuant to the requirements of North Carolina General Statutes 143-215.1
and the Memorandum of Agreement between North Carolina and the U. S. Environmental
Protection Agency.
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

Part III Permit No: NC0024201
F. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina
Chronic Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 1.3% (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 the effective date of this permit during the months of January, April, July and October.
Effluent sampling for this testing shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
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:
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 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 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.
G. POLLUTANT ANALYSIS CONDITION
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").
H. ENGINEERING ALTERNATIVES ANALYSIS CONDITION
The permittee shall continuously evaluate all wastewater disposal alternatives and pursue the
most environmentally sound alternative of the reasonably cost effective alternatives. If the
facility is in substantial non-compliance with the terms and conditions of the NPDES permit or
governing rules, regulations or laws, the permittee shall submit a report in such form and detail
as required by the Division evaluating these alternatives and a plan of action within sixty (60)
days of notification by the Division.
J. OUTFALL RELOCATION CONDITION
The permittee is hereby advised that an Authorization to Construct shall be requested from the
Division of Environmental Management prior to plant expansion. Plans and specifications
submitted to the Division for review as part of the request for Authorization to Construct shall
include the relocation of the existing discharge from Chockoyotte Creek to the Roanoke River
proper. If plant expansion is not anticipated prior to permit expiration (May 31, 1997), the
Division shall require that the outfall be relocated from Chockoyotte Creek to the Roanoke River
proper upon permit renewal. This requirement shall be a condition of the renewed permit.

This is to confirm our conversation this morning. As I indicated, the guidance memo (attached)
recommends deleting a limit for Fecal Coliform, but does suggest upstream/downstream
monitoring for evaluation during the next permit cycle. Since there will be no Fecal limit,
there is no necessity for chlorination with subsequent dechlorination.
As mentioned, every effort will be made to issue the amended permit as quickly as possible. If
you have any other questions regarding the permit, I can be reached at 919/733-5083.

The proposed permit with final limits effective May 31, 1993,
would require the District to construct a facility to disinfect
the effluent prior to discharge. In view of this and other
proposed permit requirements, the Roanoke Rapids Sanitary Dis-
trict is hereby requesting that the following items be considered
prior to final determination:
Fecal Coliform monitoring from the effective date of the per-
mit until May 31, 1993, when the existing facility does not
disinfect its effluent would yield results "too numerous to
count". Should the monitoring requirement be a part of the
interim permit?
Final permit requirements include chlorine limits (Part I -A)
and dechlorination requirements (Part III-H). Dechlorina-
tion to reduce toxicity is certainly not justified in a
river with a 7Q10 of 1000 cfs.
Virtually all recent publications including Standard
Methods, the Sacramento Manual (developed for EPA), and NC
Wastewater Treatment Operator School handouts indicate the
need for nitrogen inhibitors to reduce interference with BOD
tests. Until NC allows BOD in accordance with current tech-
nology, CBOD should be allowed as part of the proposed per-
mit.

The description of the treatment processes should be cor-
rected to include the following:
Continue to operate the existing 8.34 MGD wastewater
treatment facility consisting of a bar screen and/or
mechanical bar screen; grit chamber; dual primary
clarifiers; dual roughing trickling filters; triple
aeration basins; dual final clarifiers; dual secondary

Subject: NPDES Permit No. NC0069302
Dear Mr. Safrit:
In 1977, the Roanoke Rapids Sanitary District constructed and
placed in operation a wastewater control system to eliminate the
discharge of untreated wastewater generated by the filter back-
wash at its water treatment plant. This control system consisted
of a 0.5 MG containment basin, a mechanical mixer to keep solids
from settling, and two pumps to control the discharge to the
sanitary sewer system prior to ultimate treatment at the
District's wastewater plant.
The mixing unit failed in 1987 and required a bypass of the sys-
tem which was reported to the NCDEM regional office. Although it
was not required, a second mixing unit was added to minimize the
potential for bypass in the event of a failure. The system now
has backup pumps, backup mixing units, and auxiliary power.
NPDES Permit No. NC0069302 was issued to regulate the discharge
of untreated filter backwash should a bypass be required.
The subject permit expires on 7/31/92 and also includes the re-
quirement for renewal application at least 180 days prior to the
expiration date.
During our telephone conversation of December 27, 1991, you ques-
tioned whether this permit should be renewed since no discharge
had taken place since it was issued on 8/03/87 and only one
bypass had occurred in the 15 year history of the facility.

Mr. Donald Safrit
January 13, 1992
Page 2
Please advise if we should submit a renewal application for this
facility or if we should be authorized to continue operation and
notify the State of any bypass of this system.
Very truly yours,

Part III Permit No. NC0024201
F. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 1.3% (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 the effective date
of this permit during the months of January, April, July, and October. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes. ,
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:
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 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 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.
G. Pollutant Analysis Condition
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").
H. Dechlorination or an alternate means of disinfection is required.

Raleigh Regional Office
FROM: Betsy Johnson v�
Technical Support
THROUGH: Mike Scoville a
Ruth Swanek trOS W
SUBJECT: Roanoke Rapids Sanitary District
NPDES No. NC0024201
Halifax County
Your staff report indicates the Roanoke Rapids WWTP discharges to the mouth of
Chockoyotte Creek rather than the Roanoke River as permitted. The Roanoke River Water
Flow Committe Report confirms this. The report states that under low flow periods,
wastewater backs up in the creek causing low dissolved oxygen values.
The permit and the master file maps should be revised to reflect the actual discharge site. If
the WWTP increases its wasteflow or undergoes any construction phase, relocation of the
discharge to the Roanoke River should be examined.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
A speculative WLA on behalf of the Roanoke Rapids Sanitary District was completed last month
prior to permit renewal. The major issue associated with this discharge is that current standard
operating procedures indicat that the stream flow/wasteflow ratio is 80:1. Therefore, a fecal
coliform limitation of 200 # 00 nil is recommended. If chlorination is undertaken,
dechlorination to 0.028 m is recommended. Other current permit limitationas are being 1 7 d ,j.
recommended in this WLA. However, curre headwork analyses indicates a"limit may be 3 ' v ^.':
Pb ? rgquired. Also, a whole effluent toxicity req ement is recommended as per currentandard ''5,' t '
�' operating procedures for facility containing dustrial waste components (and major 'facilities).

Permit ti AVC0O.7(7.of
CHRONIC TOXICITY TESTING REQUIREMENT (QR"1'RLY)
The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
• using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 43 % (defined as treatment two in the North Carolina procedure
document). The permit holder shall perform quarter(v 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 JAN, APR, %A - , 0 Cr . 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: Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
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 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.

NPDES STAFF REPORT AND RECOMMENDATIONS
COUNTY: Halifax
PERMIT NUMBER: NC0024201 (renewal)
PART I - GENERAL INFORMATION
1. Facility and Address: Roanoke Rapids Sanitary District
635 Hamilton Street
P.O. Box 308
Roanoke Rapids, N.C. 27870
2. Date of Investigation: No investigation was done specifically
for this report, but a compliance evaluation and biomonitoring
inspection was conducted in February of 1991, and a compliance
sampling inspection was conducted in July of 1991. Information
from these inspections and the files was used for this report
in lieu of a site visit.
3. Report Prepared by: Rick Hiers, Environmental Engineer.
4. Person Contacted & Telephone Number: No one was contacted.
5. Directions to Site: Travel Highway 64 East from Raleigh, exit
onto I-95 North, exit east onto Highway 158 toward Weldon, travel
about one mile, turn left, and the treatment plant is at the end
of the road.
6. Location of Discharge Point.
a. Latitude: 36°26'10" Longitude: 77°36'34"
See Attached USGS Map Extract Indicating Treatment Facility Site
and Discharge Point.
b. USGS Quad Number: Weldon, NC USGS Quad Name: B28NE
7. Size (land available for expansion and upgrading): There is
adequate land available to expand/upgrade.

8. Topography (including relationship to flood plain): Based on the
USGS quad map, the treatment plant appears to be in a nearly flat
area which slopes moderately (5-10%) to Chockoyotte Creek and the
Roanoke River. The plant appears to be in the 100-year
floodplain according to the map.
9. Location of Nearest Dwelling: There is a campground about 1000
feet from the facility and there appears to be a house about 500
feet away based on the USGS quad map.
10. Description of Receiving Stream or Affected Surface Waters.
a. Name: Chockoyotte Creek
b. Classification: C
c. River Basin and Subbasin Number: 03:03:08
d. Receiving Stream Features and Pertinent Downstream Uses:
The discharge is into the mouth of Chockoyotte Creek.
According to fellow RRO staff, the creek is only a few feet
wide upstream, but has been eroded by the river to about 100
feet wide at the mouth where the discharge point is located.
There are obviously no other discharges into Chockoyotte
Creek downstream of the Roanoke Rapids discharge, and
according to the files, the only other significant nearby
discharge downstream in the Roanoke River is the Town of
Weldon's discharge, which is approximately two miles
downstream.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. Description of Wastewater.
a. Type of Wastewater: 76 % Domestic
24 % Industrial
b. Volume of Wastewater (design capacity): 8.34 MGD
c. Types and Quantities of Industrial Wastewater: The Sanitary
District has six significant industrial users which make up
the 24% industrial flow, including two textile
manufacturers, a tool manufacturer, a steam electric
cogeneration facility, a laundry, and a hospital.
d. Prevalent Toxic Constituents in Industrial Wastewater:
Constituents associated with the above industries, including
metals, oil and grease, and organics.

2. Pretreatment Program Status: In Development
X Approved
Should Be Required
Not Needed
3. Treatment System Information.
a. Status of Treatment System: X Existing
Proposed
b. Description of Treatment System: The existing 8.34 MGD
treatment system consists of a bar screen, comminutor, grit
chamber, bypass channel, dual primary clarifiers, dual
high -rate trickling filters, triple aeration basins, dual
final clarifiers, a gravity thickener, triple anaerobic
digesters, lime stabilization facilities, sludge storage
basins and tank, sludge drying beds, and all associated
pumps, meters, piping, valves, wiring, and other
appurtenances.
4. Residual Solids Treatment and Disposal Method: Land application
onto area farmland by private contractor (Permit Number
WQ0001989).
5. Treatment System Classification (rating sheet attached, if
appropriate): Class IV.
6. Codes.
a. SIC Code: 4952
b. Wastewater Code: 01
c. Main Treatment Unit Code: 04003
7. Treatment System Compliance Status: The most recent compliance
evaluation, compliance sampling, and biomonitoring inspection
reports show the facility to be in compliance. Monitoring data
from the past year shows the facility to be in compliance as
well. The Sanitary District's most recent semiannual
pretreatment report shows all of the District's significant
industrial users to be in compliance and the most recent
pretreatment audit report shows the District to be in general
compliance with Federal pretreatment regulations.

PART III - OTHER PERTINENT INFORMATION
1. Is This Facility Being Constructed With Construction Grants
Funds? The latest improvements/additions to the plant are not
believed to have been funded by Construction Grants.
2. Special Monitoring Requests: Fecal coliform due to current
policy regarding same, chlorine if used to disinfect, and whole
effluent toxicity due to industrial component of influent flow.
3. Additional Effluent Limits Requests: Fecal coliform, chlorine,
and toxicity, for reasons above.
4. Other: See below.
PART IV - EVALUATION AND RECOMMENDATIONS
The Raleigh Regional Office (RRO) has reviewed the submitted
information and the files for the subject permit renewal request.
Based on this review, it appears that the facility is in compliance
with the current permit, therefore the RRO recommends that the permit
be renewed as requested, and in accordance with the basin -wide
permitting plan.
The permit should be revised to contain all current typical conditions
for this type of discharge. Limits and monitoring should also be
included for fecal coliform, chlorine (if used to disinfect), and
whole effluent toxicity based on current policy for those parameters.
The description of the treatment system should also be revised to
reflect the current components. A schedule of one year should be
included for the installation of disinfection facilities. If
chlorination is to be used to disinfect, dechlorination is recommended
as well. Fecal coliform and chlorine (if necessary) monitoring should
be effective immediately, with limits suspended for the one-year
schedule period. One other item of note is the discharge point.
Factually, the discharge is into Chockoyotte Creek, and not into the
Roanoke River, which is shown in the current permit and which was used
to model for both the current and renewal limits. If the mouth of the
creek can be considered for the intent of modelling to be
indistinguishable from the river at the point of discharge, this is a
moot point. Otherwise, it may be beneficial to relocate or remodel
the discharge point.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Walter Taft of Piedmont risen Inc (consulting engineers for the City of Roanoke Rapids) has
requested a speculative WLA on behalf of Roanoke Rapids Sanitary District for efficient planning.
The existing oxygen consuming waste limitations are recommended, except for the
implementation of a fecal coliform limitation and a toxicity requirement. The stream flow to
wasteflow ratio is 77:1. Current tandard operational procedures dictate that a fecal coliform
limitation is necessary for ratios fair
that 331:1. A recent level B analysis indicates that
+\ eassimilative capacity of the receiving stream has been exhausted. Therefore, more stringent
permit limitationgnay be required during the next permit cycle based on the basinwide
management approach.

SUBJECT: Roanoke Rapids Instream Monitoring
City of Roanoke Rapids
NPDES No. NC0024201
Halifax County
I have reviewed the instream monitoring sites for fecal coliform bacteria proposed by the
Roanoke Rapids WWTP. Though these sites may not reflect the bacteria levels in the
area of the river which is most heavily used for recreation, they do appear to be the most
accessible sites. The permit language should be modified to include monitoring (2/mo)
for fecal coliform from April - October, at the following sites:
Upstream: 308 Rollingwood Road (Roanoke Rapids)
Downstream: US 158 Bridge over Roanoke River (Weldon)
A fecal coliform effluent limit will apply only upon expansion of the WWTP above 8.34
MGD.
If you have any questions regarding these comments, please call me at Ext. 507.

Re: NPDES Permit NC0024201

Dear Mr. Mouberry:
The proposed renewal of the subject permit will include a require-
ment for upstream/downstream monitoring for fecal coliform.
During our meeting of November 13, 1992, we were asked to propose
monitoring sites which would be accessible for monitoring and sam-
pling. The attached USGS map is marked to indicate proposed sam-
pling sites:
Upstream - 308 Rollingwood Road (Roanoke Rapids)
Downstream - U.S. 158 Bridge over Roanoke River (Weldon)
Should there be any question regarding these sites, please con-
tact me.
Very truly yours,
G. Macon Reavis, Jr.

The following comments are in response to the letter of January 22, 1992 submitted by
Roanoke Rapids.
Fecal Coliform
A first order exponential equation to model fecal coliform concentrations and applicable model
inputs for North Carolina streams indicate that a dilution ratio should be used to determine whether a
fecal coliform limit should be assigned. Standard Operational Procedures dictate that if the ratio of
downstream flow to wasteflow is less than 331:1, then a fecal coliform limit based on the corresponding
water quality standard for the classification of the stream should be assigned to new and expanding
discharges. Existing discharges should monitor the efluent, upstream, and downstream for future
evaluation of whether the facility is causing violations of the standard instream.
The permitted flow for the subject facility results in a streamflow to wasteflow ratio of 77:1.
Instream fecal data were last collected at the ambient station on the Roanoke River at Roanoke Rapids in
1986. These data showed no violation of the standard. However, this station is upstream of the WWTP.
Therefore, fecal coliform monitoring at the effluent, upstream, and downstream has been recommended
for the duration of this permit period. A decision will then be made on whether a limit is warranted.
BOD5
The permittee may have a permit limit for CBOD = 25 mg/1 in lieu of a BOD5 limit of 30 mg/l.
This is EPA's definition of secondary treatment.

Subject: Speculative NPDES Permit Limits
City of Roanoke Rapids
NPDES Permit No. NC0024201
Halifax County
Dear Mr. Taft:
I am writing in response to your letter dated February 11, 1991 concerning
possible limits for the subject facility upon NPDES permit renewal.
Effluent limitations were developed for the existing discharge location in the
Roanoke River which has a regulated flow of 1,500 cfs during the summer and a flow
of 1,000 cfs during the winter. The attached effluent limitations contain the
existing oxygen consuming waste limitations. However, a fecal coliform limitation,
a whole effluent toxicity requirement and toxic monitoring requirements have been
added.
Recent modeling analyses performed in the Roanoke River indicate that the
assimilative capacity of the river is exhausted for carbonaceous BOD. Therefore,
more stringent permit limitations may be required in the future based on a basin -
wide management approach to be implemented in 1997.
Please note that the attached effluent limitations are speculative and for use
in your engineering study. Effluent limitations can only be made final upon review
of an official NPDES permit application and issuance of an NPDES permit.

RECEIVED
FEB 1 5 1991_
Relative to our January 28, 1991 telephone conversation, subject permit is
scheduled to expire at midnight on October 31, 1991.
Within the next sixty to ninety days, it will be necessary that the Roanoke
Rapids Sanitary District prepare an application for renewal of the NPDES
permit.
In order for the Roanoke Rapids Sanitary District to plan efficiently, it
would be very helpful to know in advance of filing the NPDES application what
limits the renewal permit will contain.
On behalf of the Roanoke Rapids Sanitary District, it is respectfully
requested that a waste load allocation be conducted in order to learn of the
NPDES renewal limits. Also, please identify any new parameters to be
controlled and/or monitored.
Sincerely,
PIEDMONT OLSEN INC.
