Concurrent with this transmittal, the Division will solicit public comment on this draft by publishing a notice in
newspapers having circulation in the general Halifax County area, as required by the NPDES Program. Should you
wish to correct errors, if any, or provide comments regarding this draft, please contact the DENR / DWQ / NPDES
Program no later than 30 days after receiving this document.
In response to your request to renew the subject NPDES permit, the Division of Water Quality (the Division) hereby
transmits this draft permit for your review and comment. I encourage you read it carefully to ensure a thorough
understanding of limits and monitoring conditions.
Changes to your previous permit. The Division notes that you have completed your proposed relocation of Outfall
001 from Chockoyotte Creek to the mainstem of the Roanoke River. The Division therefore proposes significant
changes to your previous permit: we have discontinued your requirements to monitor for mercury (effluent and
upstream) and you no longer need to sample for selenium or fluoride, based on our analyses of stream and effluent
data submitted. Concerning your written request to alter the receiving-stream monitoring frequencies, this must be
denied. Your sampling frequencies for dissolved oxygen and temperature remain at 1/Week for the winter months and
3/Week during critical summer months, consistent with other Grade IV treatment works across the state.

Roanoke Rapids Sanitary District Wastewater Treatment Plant (WWTP), herein called RRSD or the
Permittee, requires a National Pollutant Discharge Elimination System (NPDES) permit to dispose
treated wastewater to the surface waters of the state. The permittee’s 5-year NPDES permit expired
March 31, 2007 and they have requested renewal from the Division of Water Quality (the Division).
This Fact Sheet summarizes background information and rationale used by the Division’s NPDES
Unit to determine permit limits and monitoring conditions.
Facility Description. RRSD WWTP (Table 1) is an 8.3 MGD, Grade IV publicly owned treatment
works (POTW) with a Pretreatment Program. The treatment system consists of a bar screen, grit
chamber, dual primary clarifiers, dual trickling filters, aeration basins, dual final clarifiers,
chlorination, dechlorination, dual secondary sludge thickeners, anaerobic digesters, lime stabilization
facility, sludge storage, and sludge drying beds. The Permittee relocated Outfall 001 to the Roanoke
River mainstem in April 2005 (DWQ received Engineer’s Certification by Shannon D. Dorsey, Reg #
29454 on April 27, 2005). This relocation date limits the renewal parameter database.

Compliance Review
Staff Report. Raleigh Regional Office (RRO) conducted its annual facility inspection and Myrl
Nisely prepared a Staff Report dated November 30, 2006. The RRO staff found the facility in good
condition and in compliance with the permit; they recommended that the NPDES Program renew the
permit in accordance with the Basin Plan.
Reasonable Potential Analyses (RPA) - Pollutants of Concern (POCs). The Division restricted the
RPA database timeframe to April 2005 through December 2006 because the Permittee relocated Outfall
001 from Chockoyotte Creek to the mainstem of the Roanoke River (IWC =1.1 %), as provided in the
previous permit. To establish POCs, the Division reviewed the permit application, discharge monitoring
reports (2003 through 2006), pretreatment data, and the Basin Plan. The Division applied the standard
Reasonable Potential Analysis (RPA) to calculate a maximum predicted concentration for each POC.
Each maximum vw, then compared to the POC’s freshwater Chronic Standard (Table 2) and also to its
Final Acute Value ('/z FAV) for freshwater (Table 3).
If by the above method, a POC showed reasonable potential to exceed its /i FAV, the Division
included a permit limit as a Daily Maximum to protect the receiving stream against acute toxic
affects. Similarly, if the maximum exceeded the chronic standard, a Weekly Average limit was added
DMR Instream Data and Effluent Flow Review. The Division reviewed 48 months of monthly
Discharge Monitoring Reports (DMRs) for January 2003 through December 2006. The Permittee’s
DMRs for these years appear regular, thorough, and complete. The Division compared daily flows for
years 2004, 2005, and 2006. These data yield a 3-year average flow of 4.37 MOD, or discharge about
52 % of permitted capacity.
Verifying Existing Stream Conditions. This segment of the Roanoke River is not impaired, but
the down-river segment [Stream Index No. 23-(53)J is identified as impaired for dioxin [DWQ 303(d)
list, February 2003].

Waste Load Allocation (WLA). As of April 2005, this facility discharges to the mainstem of the
Roanoke River [Stream Index No. 23-(26)], a Class C waterbody within the Roanoke River Basin.
The Division prepared a WLA for the receiving stream in December 1996 (eventual dilution by the
Roanoke River) and developed effluent limits and monitoring requirements considering an in-stream
waste concentration (IWC) of 1.1 % at 8.4 MGD. The Division views these limits and monitoring
requirements appropriate for renewal except as outlined below (see Renewal Summary).
Division Records and Permittee’s Renewal Application. The current permit expired on March 31,
2007, and the Division received the Permittee’s prompt request to renew (Standard Form C) on
October 4, 2006. The application included a request to remove effluent and upstream monitoring
requirements for mercury, based on data indicating “not detected” (Because of high dilution by the
receiving stream, RRSD is not required to use EPA test method 163 IE for mercuiy). This request
will be granted (see RPA). The Permittee also requested to reduce monthly instream sampling
frequencies. Based on WWTP Grade IV requirements, this request will be denied.

Dear Mr. Brown:
R. Danieley Brown
Roanoke Rapids Sanitary District (RRSD)
1000 Jackson Street, P.O. Box 308
Roanoke Rapids, North Carolina 27870
If any parts, monitoring 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. You must submit this request in the form of a written petition, conforming to Chapter
150B of the North Carolina General Statutes, and file it 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.
The Division of Water Quality (the Division) hereby issues the attached NPDES permit for the subject
facility. We issue this permit 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 May 9, 1994, or as subsequently amended.
The Division has reviewed your comments on the draft permit dated May 14, 2007 and have corrected
several noted typographical errors. We also offer the following additional responses to your comments.
• Permit Part II, Definition of “Daily Maximum” for Total Residual Chlorine (TRC) and pH.
You may collect multiple samples in a given day (24 hours) for TRC or pH, but you may not
composite these samples nor average the analytical results. Moreover, you must report all
individual analyses acquired. To comply with the permit Daily Maximum, compare your permit
limit to your daily, single-sample-event highest concentration.
• Copper and Zinc Monitoring. The Division evaluated your effluent data using Reasonable
Potential Analyses (RPA), as required. This model evaluates, not only reported values, but also
dataset variability. Based on RRSD’s copper and zinc data, both metals show reasonable potential
to exceed their respective acute ('A Fav) standards (see attached Fact Sheet and RPA results).
Therefore, based on state requirements for action level parameters, continued monthly monitoring
for copper and zinc is required. Should toxicity failures become an issue in the future, these
parameters may require permit limits.

A. (2.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
North Carolina Division of Water Quality
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 1.1 %.
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 test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality
indicate potential impacts to the receiving stream, this permit may be re-opened and modified to include alternate monitoring
requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later than
the last day of the month following the month of the initial monitoring.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival. The definition of “detectable impairment,” collection methods, exposure regimes, and
further statistical methods are specified in the “North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure”
(Revised-February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form
(MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B
for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the
end of the reporting period for which the report is made.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the “North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure,” Revised February 1998, or subsequent versions or “North Carolina
Phase II Chronic Whole Effluent Toxicity Test Procedure” (Revised-February 1998) or subsequent versions. The tests will be
performed during the months of January, April, July and October. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then
multiple-concentration testing shall be performed at a minimum, in each of the two following months as described in “North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure” (Revised-February 1998) or subsequent versions.
Attention:
Environmental Sciences Section
1621 Mail Service Center

Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response
data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the
effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should the Permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required
during the following month.

Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant dme/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters- Use of this method
