Subject: NPDES Permit No. NCO036269
Rocky River WWTP
Cabarrus County, NC
Dear Mr. Furr:
Our records indicate that NPDES Permit No. NC0036269 was issued on September 27, 2004
for the discharge of wastewater to the surface waters of the State from your facility. The purpose
of this letter is to advise you of the importance of the Permit and the liabilities in the event of failure
to comply with the terms and conditions of the Permit. If you have not already done so, it is
suggested that you thoroughly read the Pen -nit. Of particular importance is Pages 4, 5, 6 and 7.
Pages 4, 5, 6 and 7 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth. The section headed
"Monitoring, Requirements" describes the measurement frequencies, sample types and sampling
locations. Upon commencement of your discharge (or operation), you must initiate the required
monitoring. The monitoring results must be entered on reporting forms furnished or approved by
this Agency. If you have not received these forms, they should be arriving shortly. If you fail to
receive the forms, please contact this Office as quickly as possible. I have enclosed a sample of the'.
"Effluent" reporting form (DWQ Form MR-1), plus instructions for completing the form. It is
imperative that all applicable parts be completed, and the original and one copy be submitted as
required.
Please. be advised that an annual administering and compliance monitoring fee may be '
required for your facility. You will soon be receiving a statement from our Raleigh Office. It is
imperative that the fee be paid in a timely manner so as to prevent enforcement action or possible
one revocation of your permit.

The remaining parts of the Permit set forth definitions; general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The
conditions include special reporting requirements in the event of noncompliance, bypasses, treatment
unit/process failures, etc. Also addressed are requirements for a certified wastewater treatment plant
operator if you are operating wastewater treatment facilities. Any changes in operation of
wastewater treatment facilities, quantity and type of wastewater being treated or discharged,
expansions and/or upgrading of wastewater treatment facilities must be permitted or approved by
this Agency.
Failure to comply with the terms and conditions of an NPDES Permit subjects the Permittee
to enforcement action pursuant to Section 143-215.6 of the North Carolina General Statutes. A civil
penalty of up to $25,000 per violation (and/or criminal penalties) may be assessed for such
violations. If you find at any time that you are unable to comply with the terms and conditions of
the Permit, you should contact this Office immediately. A Special Order by Consent (SOC) may be
necessary while pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a five-year period. Permits are not
automatically renewed. Renewal requests must be submitted to this Agency no later than 180 days
prior to expiration. Please make note of the expiration date of your Permit. This date is set forth on
Page 1 of the Permit. Also note that NPDES Permits are not automatically transferable. If you, as
the Permittee, cease to need this Permit, then you should request that the Division of Water Quality
rescind the Permit.or request that DWQ reissue the Permit to another parry, if necessary.
As mentioned previously, the purpose of this letter is to advise you of the importance of your
NPDES Permit. Please read the Permit and contact this.Office at 704/663-1699 in Mooresville if
you have any questions or need clarification. We look forward to providing any assistance.

Subject: Issuance of NPDES Permit NOJ036269
Rocky River WWTP
Cabarrus County
Division personnel have reviewed and approved your application for renewal of the subject permit.
Accordingly, we are forwarding the attached NPDES discharge 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 US. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended).
This final permit includes no major changes from the draft permit sent to you on August 4, 2004.
This permit includes a TRC limit that will take effect on May 1, 2006. If you wish to install dechlorination
equipment, the Division has promulgated a simplified approval process for such projects. Guidance for approval of
dechlorination projects is attached.
The Division recommends that you consider ultraviolet (UV) disinfection for your facility. Chlorine can be
acutely toxic to aquatic organisms and forms secondary compounds that can also be detrimental to aquatic life. UV
disinfection would reduce the chemical load in your facility's effluent and reduce risks to aquatic life instream.
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 demand is made, this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. 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 or permits required by the Division of Land
Resources, the Coastal Area Management Act or any other Federal or Local governmental permit that may be
required. If you have any questions concerning this permit, please contact Sergei Chernikov at telephone number
[phone], extension 594.

SUPPLEMENT TO EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (3) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The permittee shall conduct chronic toxicity tests using test procedures outlined in the "North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure" (Revised -November 1995) or subsequent versions.
The effluent concentration defined as the Instream Waste Concentration (IWC) shall be at the following flow -dependant
effluent concentrations: 59.6% (24 MGD); and 67.7% (34 MGD). The chronic value 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 presence of 48 hour acute toxicity will
be determined using Fisher's Exact Test at 48 hours from test initiation. The definition of "detectable impairment," collection
methods, exposure regimes, and further statistical methods are described by the document referenced above.
The permit holder shall perform at a minimum, quarterly monitoring using these procedures to establish compliance with the
permit condition. The tests will be performed 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.
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.
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 THP3B for the Chronic Value and TGA3B for
the 48 hour Acute Toxicity measure (Pass/Fail). Additionally, DWQ Form AT-3 (original) is to be sent to the following
address:
Attention: NC DENR / DWQ / Environmental Sciences Branch
4401 Reedy Creek Road
Raleigh, NC 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 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 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 valid test is submitted. Upon submission of a valid test, 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 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.

A. (5) CLARIFICATION OF COMPLIANCE WITH PERMIT LIMITS SET AT OR BELOW
MINIMUM LABORATORY PROCEDURE LEVELS
1. The following definitions apply to this permit [REF: EPA National Guidance for the Permitting, Monitoring
and Enforcement of Water Quality -Based Effluent Limitations Set below Analytical Detection/ Quantitation
Levels (DRAFT), March 22, 1994].
The Method Detection Limit (MDL), as defined by a specific laboratory method, is the minimum
concentration that can be measured and reported with 99 percent confidence that the parameter is greater
than zero (i.e., the analyte is detectable or identifiable at this level, but not quantifiable).
The Minimum Level (ML) is higher than the MDL, and is defined as the sample concentration
equivalent to the lowest detectable level of the calibration standard not requiring extrapolation, i.e. the
lowest quantifiable level, as defined by a specific analytical procedure.
2. In cases where the Division sets a parameter limit at the ML (as required to protect the receiving -stream
environment), the Division shall consider any report of that parameter at or below the ML to be in
compliance.
• Example 1: If the ML is 10.0 µg/L and the permit limit is 10.0 µg/L, any report of 10.0 µg/L or <10.0
µg/L shall be considered compliant with the permit.
3. In cases where the Division sets a parameter limit below the ML (as required to protect the receiving -
stream environment), the Division shall consider any report of that parameter below the ML to be in
compliance.
• Example 2: If the ML is 10.0 µg/L and the permit limit is 2.0 µg/L, a report of 101ig/L shall not be
compliant, but a report of <10.0 shall be considered compliant.
A. (6.) CLARIFICATION OF SAMPLE COLLECTING UNDER HAZARDOUS CONDITIONS
In accordance with North Carolina State Regulations 15A NCAC 213.0505(c)(4), the permittee may discontinue
receiving -stream monitoring and sample collecting when flow conditions or extreme weather conditions could
result in injury or death of the person(s) collecting the samples. In such cases on the day of sampling, the permittee
shall record and justify the discontinuance, and furthermore, shall include this justification in that month's
monitoring report. This provision shall also apply to influent and effluent sampling.

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

Subject: Issuance of Permit Modification to Remove
MBAS Limits and Monitoring
NPDES Permit No. NCO036269
Rocky River Regional Wastewater Treatment Plant
Cabarrus County
Dear Mr. Shive:
Please be advised that the North Carolina Environmental Management Commission (EMC) has
modified the rule requiring limits and monitoring in permits for Methylene Blue Activated
Substances (MBAS), effective April 1, 2003. The EMC has ruled that MBAS concerns are
aesthetic in nature and that discharge monitoring and limits shall apply to water supply (WS)
classified waters only.
Therefore, the Division of Water Quality (the Division) hereby modifies and reissues WSACC's
permit to remove MBAS monitoring and limits (as detailed in the Settlement Agreement meeting
of May 9, 2001 and subsequent correspondence). The Division received no public comments
during the required public notice period for this modification. Moreover, the Division's
Toxicology Unit, the Mooresville Regional Office, and the EPA Region 4 have concurred with the
need for modification.
Attached, please find change -pages incorporating all permit modifications. Please insert these new
pages into your existing permit and discard the old pages.
If any parts, measurement frequencies, or sampling requirements contained in this permit
modification are unacceptable, 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 modification shall be final and binding.

RE: NPDES PERMIT RENEWAL APPLICATION FOR -THE
WATER & SEWER AUTHORITY OF CABARRUS COUNTY,
NPDES PERMIT NO. NCO036269
ROCKY RIVER REGIONAL
WASTEWATER TREATMENT PLANT, CABARRUS COUNTY
Dear Mrs. Stephens:
The Rocky River- Regional Wastewater Treatment Plant (RRRWWTP) is
currently permitted to discharge 24 MGD to . the Rocky River under Permit No.
NC0036269, which expires on October 31, 2004. There is language and limits in the
current permit that allows for expansion to 34 MGD. This application is submitted for
renewal of the current permit in accordance with the requirement to apply for renewal six
months prior to the expiration of the current permit. Please find enclosed three (3) copies
of the application for the subject permit.
Planned Facility and Operational Changes
Since the Water and Sewer Authority of Cabarrus County's (WSACC) last permit
was issued, the new headworks facility was completed. The facility consists of two 3/8-
inch climber type barscreens, two vortex grit removal basins, and two parshall flumes for
influent flow metering.
An upgrade of the RRRWWTP began on December 16, 2001, and is scheduled to
be completed in July of 2004. The upgrade includes the following improvements:
• Variable speed drives on two existing influent pumps. This will reduce
surges in our flow pattern.
• Secondary clarifier weir modifications, serpentine weirs will be replaced
with straight weirs for easier maintenance. (complete).
• Alkalinity addition.
• Odor control system.
• RAS automotive flow controls.
• Plant automation control system.
• Standby power generators.
The plant expansion to 34 MGD has been postponed until the plant effluent flow
reaches the 90% mark of our current 24 MGD limit. This is estimated to be in the year
2016.

Mrs. Stephens
Requests for Permit Renewal
We would appreciate the Division of Water Quality (DWQ) considering the
following requests for this permit renewal: We have grouped information into the
following areas:
A. Tiered Permit
B. 7Q10 Determination
C. Mercury
D. Cyanide
E. Total Residual Chlorine
F. Supplement to Effluent Limitations and Monitoring Requirements
— Special Conditions
G. Other
H. Sludge Management Plan
A. Tiered Permit
WSACC's current permit limits are calculated using a tiered flow rating of 20 MGD,
24 MGD, 28 MGD and 34 MGD. We request that the new permit incorporate the
following tiers and conditions:
• 24 MGD- During the period beginning on the effective date of the permit and
lasting until the Division receives an Engineer's Certification of Completion
for expansion above 24 MGD, or permit expiration, the Permittee is
authorized to discharge from Outfall 001.
• 34 MGD — During the period beginning with the receipt of an Engineer's
Certification of Completion for expansion above 24 MGD and lasting until
permit expiration, the Permittee is authorized to discharge from Outfall 001.
B. 7Q10 Determination
The calculation of the 7Q 10 value for low flow in the Rocky River is a critical
determination and has significant impacts on the NPDES Permit limits that are
issued for the RRRWWTP. In 2003, the USGS published the Water -Resources
Investigations Report 03-4147, "Low -Flow Characteristics and Profiles for the
Rocky River in the Yadkin -Pee Dee River Basin, North Carolina, through 2002".
On page 17 of this report, USGS lists the 7Q10 and winter 7Q10 (W7Q10) at their
gaging station 900 feet prior to the RRRWWTP discharge. The 7Q10 is listed at
25.2 ft 3/seconds and the W7Q10 at 35.2 ft 3/seconds. We request that the
summer limits of our NPDES Permit be based on calculations using the 25.2 ft
3/seconds 7Q10, and the winter limits be calculated with the 35.2 ft 3/seconds
W7Q10. Page 17 of the report is attached. We request. that the IWC for
RRRWWTP be recalculated to reflect the new 7Q10 levels, as established by
USGS.

Mrs. Stephens
C. Mercury
WSACC understands the problems associated with the discharge of Mercury to
the environment. We have undertaken numerous actions to minimize the
contribution of Mercury into WSACC's sewerage and treatment systems. Based
on our efforts conducted over the past several years, we have been able to
substantially reduce the measurable Mercury concentrations in the RRRWWTP.
This is supported by the three low-level Mercury samples collected for this permit
application. The highest level detected was 4.2 ng/L, which is well below the
water quality stream standard of 12 ng/L.
Based on the Mercury data described above, we request that, like our .current
permit, Mercury monitoring and limits not be included in our new permit.
D. Cyanide
As listed in our last permit application, the RRRWWTP made some operational
changes to improve cyanide destruction. Again in 2003 we increased the aerobic
detention times in the aerobic basins by increasing the volume of the aerobic
zones (from 3.74 MG to 5.98 MG). It is well understood that cyanide, at lower
non -toxic levels, acts as a readily degradable carbon source for aerobic bacteria.
The 37% increase in aerobic detention time permitted an increased biological
treatment contact time that related to a decrease in effluent cyanide levels. The
past three years of Cyanide data supports the operational changes because all of
the test results are below the Quantitation level.
Therefore, we request that the permit limit for Cyanide be omitted from our new
permit.
E. Total Residual Chlorine (TRC)
In negotiations for our current permit, WSACC and DENR reached an agreement
on August 27, 2002, that the RRRWWTP would not have a TRC limit, but would
monitor TRC, until the flow limitation exceeded 24 MGD. WSACC has
monitored for TRC since the agreement (436 samples), and the results show a
TRC average of 93 ug/L, with a maximum level of 370 ug/L. During this time
period, the RRRWWTP has passed all of its bioassays with a NOEC 99% at
Effluent.
We are requesting that a TRC limit not be imposed until the flow limitation
exceeds 24 MGD and all monitoring be discontinued until the limit takes effect.
F. Supplement to Effluent Limitations and Monitoring Requirements — Special
Conditions
Included in our current permit is a section titled; Supplement to Effluent
Limitations and Monitoring Requirements Special Conditions. We are requesting

e
Page 4
April 27, 2004
Mrs. Stephens
that this section, and the current language in A. (6) and A. (7), be included in our
new permit.
G. Other
In the event that WSACC experiences the loss of reportable monitoring
information due to events beyond its control, WSACC requests the following
language be included as a Special Condition in the NPDES permit:
"The loss of acceptable monitoring data shall not constitute a violation of this
permit provided the cause of the loss was unavoidable by the permittee and/or
was beyond the permittee's control. Examples of such a loss include: samples
lost or delayed during shipping and improperly performed analyses (incorrect
analytical methods, expired holding times caused by the laboratory, over -or -
under -dilution of samples, contamination in the laboratory, etc.). The permittee
shall re -sample immediately upon learning of the sample loss. In such cases, on
each event that samples are lost, written justification for the loss shall be specified
in the monitoring report for the month in which the loss occurred. This provision
shall be strictly construed and may.not be utilized to avoid the requirements of
this permit when performance of all monitoring requirements is attainable."
WSACC requests that any changes in monitoring requirements or limitations be
based on site -specific studies. These requirements and changes should not be
considered as a variance to the water quality rules.
With the loss of our largest industrial user (Pillowtex), the characteristics of our
influent flow to the plant have changed considerably since the original design
work was completed. WSACC is asking for language in the permit that allows us
to have a hydraulic study completed and open the permit to increase the plant
design flow if justified. The study would be completed before the end of calendar
year 2004.
H. Sludge Management Plan
The primary sludge disposal method at the RRRWWTP is incineration, permitted
by the Division of Air Quality Permit No. 4475R14. In the event of failure of the
incineration operation, the sludge will be taken to the BFI Landfill, Harrisburg,
N.C. for disposal. Approval from BFI and the Division of Solid Waste has been
obtained for the disposal of both ash and sludge.
The ash is collected in a dual -chamber ash holding basin which has an eight year
capacity. Ash has been sent to the BFI Landfill and was used as daily top cover.
We are pursuing other ash disposal options which include agricultural, structural
fill, and building material applications. Ash has also been used in the
manufacturing of bricks. A new brick manufacturer is being sought.

Mrs. Stephens
Please provide the Fact Sheet prepared as part of .the Draft Permit development as
soon as it is available, with justification, if any changes to the permit limits or conditions
are proposed. Please include with the Fact Sheet NCDENR documentation that outlines
the policies on the use of metals partitioning and bioavailability in developing permit
limits, policies or procedures related to establishing monitoring requirements, and
procedures to remove monitoring requirements.
WSACC has previously had problems receiving complete, legible, and timely
copies of the draft NPDES permit from NCDENR. Based on past experience, WSACC
finds it necessary to request that NCDENR provide a clean, hard copy of the Draft Permit
and Fact Sheet to WSACC at a minimum of 30 days prior to the public notice.
Thank you for your consideration of our requests. If you should have any
questions during your review or need additional information, please don't hesitate to
contact me at [phone], ext. 11 or Lynn Bishop, Wastewater Operations Manager
at ext. 14. -

POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the facility's
discharge points: 1) POTWs with a design flow rate greater than or equal to 1.0 mgd; 2) POTWs with a pretreatment program (or those that are required to have
one under 40 CFR Part 403); or 3) POTWs required by the permitting authority to submit data for these parameters.
• At a minimum, these results must include quarterly testing for a 12-month period within the past 1 year using multiple species (minimum of two species),
or the results from four tests performed at least annually in the four and one-half years prior to the application, provided the results show no appreciable
toxicity, and testing for acute and/or chronic toxicity, depending on the range of receiving water dilution. Do not include information on combined sewer
overflows in this section. All information reported must be based on data collected through analysis conducted using 40 CFR Part 136 methods. In
addition, this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC requirements for standard methods for
analytes not addressed by 40 CFR Part 136.
• In addition, submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test conducted
during the past four and one-half years revealed toxicity, provide any information on the cause of the toxicity or any results of a toxicity reduction
evaluation, if one was conducted.
• If you have already submitted any of the information requested in Part E, you need not submit it again. Rather, provide the information requested in
question EA . for previously submitted information. If EPA methods were not used, report the reasons for using alternate methods. If test summaries are
available that contain all of the information requested below, they may be submitted in place of Part E.
If no biomonitoring data is required, do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to complete.
