Subject: Issuance of NPDES Permit
NC0046728
Rocky River WWTP
Iredell County
Dear Mr. Martin:
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 U.S. Environmental Protection Agency dated May 9,1994 (or
as subsequently amended).
This final permit includes the following changes from your draft permit:
➢ The results of the priority pollutant analysis submitted by your facility revealed the presence of
several pesticides. Endrin, beta-BHC, and heptachlor were each shown in two of the three tests
submitted. Limits for these parameters will become effective in 18 months (July 1, 2006). The
Division encourages you to aggressively pursue the sources of these contaminants. If, within 18
months, you can demonstrate that these are not pollutants of concern you may petition for
removal of these permit requirements.
➢ The TRC implementation schedule has been extended from 18 to 24 months as per your request.
The limit will become effective January 1, 2007. 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.
In your comments on the draft permit you mentioned that Mooresville will soon be expanding
the WWTP from 5.2 MGD to 12 MGD. We highly recommend that you submit a speculative limit request
letter prior to developing the engineering alternatives analysis (EAA) and application for the new permit.
It is possible that your limits at 12 MGD will be different than your current limits. We also recommend
that you check our website for the recently updated EAA guidance at:
http: / /h2o.enr.state.nc.us /NPDES/documents.html.
Please note that since the proposed expansion is for more than 0.5 MGD, this project falls under
the State Environmental Policy Act (SEPA) and you will be required to submit an Environmental
Assessment to the SEPA program. You can find more information at http://h2o.enr.state.nc.us/sepa/.
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 Toya Fields at telephone number [phone], extension 551.

Permit NC0046728
A(2). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 90%.
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 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.
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:
Attention: NC DENR / DWQ / Environmental Sciences Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30
days after the end of the reporting period for which the report is made.
Test data shall be complete, 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 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, monitoring will be
required during the following month.
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.

Toya,
The method detection limits (MDLs) published in EPA method 608 are
as follows:
Endrin 0.006 ug/L
Heptachlor 0.003 ug/L
Beta-BHC 0.006 ug/L
This test is done with GC/ECD (gas chromatograph/electron capture
detector). It is a very common and sensitive method to analyze for
these compounds. However the practical quantitation limits (PQLs)
are usually 3 to 5 times above these levels. PQLs represent the more
real -world, day to day, operations in a lab. Our lab reports values
above the MDLs and below the PQLs with a qualifier. There may be more
sensitive methods, but EPA method 608 is probably the most commonly
used method for reporting permit values.

Hi Pat,
I have a question about endrin, heptachlor, and beta-BHC. According
to the PPAs we have, the quantitation limits for these are 0.06
ug/L, 0.05 ug/L, and 0.05 ug/L respectively. Are there any tests
available that can get below these values? I may need to put limits
in a permit for these. The limits would be as follows:
endrin: 0.002 ug/L
heptachlor: 0.0065 ug/L
beta-BHC: 0.075 ug/L
Is there anything available that tests this low? Actually, now that
I look at it, the limit for beta-BHC is high enough that the
quantitation level for the method they are using would be fine.
Thoughts? Thanks,

Yes, that would be our preference. I think if we gave the Town limits with an
18-month compliance schedule (as Marshall Hyatt suggested), then it would
"encourage" the Town to aggressively go after the source(s).

Hi Michael,
So your preference would be that we add monitoring for the three pollutants that
have multiple detections rather than add the special condition? Just want to make
sure I'm clear.
Thanks,

Toya,
Considering how much above the stream standards some of these
values are,
our staff feels that we need to consider adding monitoring unless
the Town
can quickly identify and remove the sources of these pollutants.
The Town
should at the least provide us with a plan on how they expect to
find the
source(s), but I don't know that it is necessary that we include
it in the
permit.

gamma BHC (lindane) - 0.19 ug / L
endosulfan I (alpha) - 0.11 ug/L
endrin - 0.073 ug/L
heptachlor - 0.079 ug/L
There are multiple detects for endrin, beta BHC and heptachlor.
Rather
than add monitoring for these parameters, I suggested that we
add a
special condition asking the facility to determine the sources
for these
pollutants and develop a plan for their elimination within one
year.
I'd ask for the report to be sent to your office. Do you have
any
thoughts or concerns about this?
Thanks,

I'll answer this way. NC's reasonable potential procedures say that
limits can be based on single data pts, even though more data is
preferred. Why not handle it by including what I call a conditional
limit. Go ahead and give the facility limits for these parameters
with
an 18 month compliance schedule. Include a condition that the limit
can
be withdrawn/deleted upon writting notification from the permitting
authority. Give the facility the opportunity to collect more data in
the interim (10 data pts or so). If they submit that data over the
next
yr and it shows no RP, you can write a letter to them deleting the
limit
w/o having to go to PN for a permit mod.
does this make sense? Would this work for you and the Region?

forgot to add one thing...
hope hese are useful. Marshall
The PPA data that you sent shows several single detects for
various
pesticides. It also shows multiple detects for endrin, Beta BHC,
and
heptachlor. Most, if not all, detects are above NC's criteria.
based
on tl s info, how will you address this in the permit?
the parameter name and in footnote 2 in Part A.1, recommend
cha ing "total suspended residue" to "total suspended solids".
For
you
get
For
temperature, recommend adding "degrees F" or "degrees C", so
info you want.
TN and TP, recommend adding "as N" and "as P".
pH should be expressed as "6.0-9.0", rather than "6-9".
6. Because is facility is a pretreatment one, the fact sheet
needs to
contain the standard language that says the city will be required in
the
permit to continue to implement its pretreatment program.

POINT SOURCE BRANCH
I have reviewed the draft permit for the Town of Mooresville's permit renewal. I have the
following comments.
1. Your letter states that the TRC limit will take effect in 18 months from the effective
date of the final permit. If we submit comments and receive a reply by September,
and we were to receive a final permit by October of this year it would create a
problem for us. The reason it would be a problem is that we would have to install
dechlorination facilities which are not budgeted for fiscal year 2004/2005 and we
would have to wait until fiscal year 05/06 budget which would gives us only 8 months
to design and construct these facilities. This would not be possible. We would like
to request 24 months after the final permit is received.
Ok
2. Your letter requests three priority pollutant analyses and four toxicity test other than ceriodaphnia. I have attached the three PPA's and two fathead minnow reports in OIL -
triplicate. We are scheduled to run the other two fathead minnow reports this year
and we will submit this data as soon as we get it.
3. On the cover page it still shows the drying beds and static screens as part of the \L
process. They have were taken out of service a number of years ago, so they
should no longer be shown as being in use.
I also wanted to let you know that the Town of Mooresville will be requesting Request for
Qualifications (RFQ's) from 15 engineering firms this week to provide design and
construction management to enlarge the current 5.2 MGD IN TP to 12 MGD. It is
estimated that this project will take approximately 48 months to complete if everything goes
right. We will be coming to you in the future months to apply for that permit. I don't know if
that will affect the current permit renewal or not. Would we complete the current permit

P
renewal and receive a final permit and work under it until the new plant is permitted?
Please let me know if that would be the correct procedure. Should you require additional
information please contact me.
Cordially,
Wilce Martin

2.0 Summary
The Town of Mooresville has applied for permit renewal for their Rocky River WWTP.
This facility is currently permitted for a 5.2 MGD discharge. According to the last WLA (1993)
the facility's waste stream was 56% domestic waste and 44% industrial, however several SIUs
have rescinded their IUPs since that time. Based on the permit application, Best Sweet
confectionary manufacturer, Robert Yates metal finishing, and Meritage, LLC garment dyeing
and finishing are the only SUIs.
Rocky River WWTP discharges to Dye Creek. Dye Creek is listed on the 2002 303(d) list
as impaired due to sediment based on biological impairment. Potential sources are listed as
municipal pretreatment (indirect), agriculture and urban runoff/storm sewers. The 1998 basin
plan specifically discusses impacts to the upper Rocky River from toxicity failures at the WWTP.
When Burlington Industries (a former SIU) closed, it appears that the toxicity problems ceased,
however the plan also recommended that DWQ review the DO limit for the facility should an
expansion occur. The 2002 basin plan recommends further investigation into the causes of
impairment of this stream segment.

3.0 Compliance Summary
DMR Data Review
NC0046728
2001-2004 DMR was reviewed for this permit renewal. Rocky River's average flows appear to be
at 49% capacity, with maximum monthly flows at approximately 67% capacity. The facility
appears to be operating well within its permitted limits. Although D.O. levels have historically
been a concern in the receiving water, this discharge does not appear to be contributing to any
problems instream due to relatively high D.O. levels in the effluent. Table 1 summarizes monthly
average DMR data for the review period.

The Rocky River WWTP is a member of the Yadkin Pee Dee River Basin Association, so
its instream monitoring requirements are waived. At this time, however, there are no coalition
monitoring stations in the vicinity of the discharge.
PPA results
The results of the priority pollutant analysis submitted by the facility revealed the
presence of several pesticides. Endrin, beta-BHC, and heptachlor were each shown in two of the
three PPAs submitted. After speaking with both EPA Region 4 and the DWQ regional office, it
was determined that the best course of action in this case would be the inclusion of a conditional
limit. This is intended to give the town time to determine the cause of the pollutants before a limit
takes effect. Limits for the three parameters will become effective in 18 months (July 1, 2006) with
monthly monitoring until that time. If within 18 months they can demonstrate that there is no
reasonable potential for their effluent to cause an exceedance of WQ standards for these
pollutants, they may petition for removal of the limit and related monitoring requirements.
RPA Analysis
RPAs were conducted for all parameters of concern: cyanide, lead, copper, and zinc.
Although effluent levels for both copper and zinc appear to be above the stream standard, the
facility's effluent does not appear to be toxic based on chronic WET test results; therefore they
will not receive limits for these parameters. Monthly monitoring will remain in the permit.
According to the RPA, the maximum predicted concentration for cyanide is 5 µg/L
(equal to the allowable chronic concentration). However, there were only 7 detections out of 83
samples analyzed. All detected levels were below the PQL. In addition, since the predicted
concentration is so far below the allowable acute value (22 µg/L), the permit limit will be
removed and monitoring reduced.
The lead limit will be removed and monitoring reduced due to a lack of reasonable
potential for the discharge to cause an exceedance of lead water quality standards. In late 2001,

NPDES Permit Fact Sheet — 12/15/04 Town of Mooresville/ Rocky River WWTP
Page 3 NC0046728
the facility did exceed its lead limit, but the source appeared to be an isolated contamination of
unknown origin. 76 samples were used for the RPA analysis and out of that data there were only
7 detected values. Lead does not appear to be a parameter of concer.
Limited LTMP data was available for the following parameters:
• Arsenic • Selenium • Beryllium
• Aluminum • Silver • Chloride
• Chromium • Mercury • Fluoride
• Molybdenum • Antimony
• Nickel • Barium
Only 3-6 data points were available for each parameter- less that the 8-12 recommended for an
RPA analysis, however all of the analyses showed levels that were either below the detection
limit or at low levesl that would not cause an exceedance of water quality standards.
WET Test Results
Rocky River WWTP has passed 15/17 WET tests issued since January 2000. The two
failures were in 8/00 and 2/03. The failure in 2/03 was caused by overfeeding polymer.
Correspondence File Review/Compliance History
The facility has been in compliance with its permitted limits with the exception of a brief
string of lead violations in late 2001. Correspondence from that time period suggests that the
lead came from a single, isolated source.

5. Directions to site: From the jct. of NC Hwy. 3 and Johnson Dairy Rd. (SR 1142) southeast
of the Town of Mooresville, travel west on Johnson Dairy Road approx. 0.7 mile. The
entrance to the WWTP site is on the right (north) side of Johnson Dairy Road via a paved
access road.
6. Discharge point(s), list for all discharge points: -
Latitude: 35° 31' 33"
Longitude: 80° 46' 56"
Attach a USGS Map Extract and indicate treatment plant site and discharge point on map.
USGS Quad No.: E 15 SE
7. Site size and expansion area consistent with application: Yes. Area is available for
expansion, if necessary.
8. Topography (relationship to flood plain included): Rolling topography, 2-8% slopes. The
WWT facilities have been constructed above any flood plain.

Page Two
9. Location of nearest dwelling: Approx. 500+ feet from the WWTP site.
10. Receiving stream or affected surface waters: Dye Creek
a. Classification: C
b. River Basin and Subbasin No.: Yadkin 030711
c. Describe receiving stream features and pertinent downstream uses: Flow was
observed in the receiving stream which is approx. 4-5 feet wide and 4-8 inches deep
at the point of discharge. The effluent from this facility no longer causes a
discoloration of the receiving stream since the Town lost a major textile dying
operation in 1999. Downstream uses are primarily agriculture. The receiving stream
is listed on the FY 2002 303(d) list as impaired. Sediment is listed as the cause of
impairment. Aquatic life (minnows) were observed immediately below the discharge
point.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. a. Volume of Wastewater: 5.2 MGD (Design Capacity)
b. What is the current permitted capacity: 5.2 MGD
c. Actual treatment capacity of current facility (current design capacity): 5.2 MGD
d. Date(s) and construction activities allowed by previous ATCs issued in the previous
two years: There have been no ATCs issued in the past two years.
e. Description of existing or substantially constructed WWT facilities: The existing
WWT facilities consist of an influent screw pump station, dual static screens, dual
aeration basins with mechanical (fixed) aerators, dual final clarifiers, dual aerobic
digestors, gaseous disinfection with contact chamber, post aeration, vacuum sludge
drying beds, and stand-by power.
f. Description of proposed WWT facilities: There are no proposed WWT facilities at
this time. If dechlorination limits are applied to this discharger, then dechlorination
facilities will be required.
g•
Possible toxic impacts to surface waters: Chlorine is added to the waste stream. The
Town has passed recent toxicity tests performed under the terms of the Permit,
however, past toxicity tests failures have been recorded during sampling inspections
conducted by MRO staff. It is believed that the toxicity failures are related to the high
chlorine residual in the effluent.
h. Pretreatment Program (POTWs only): The Town has an approved pretreatment
program.

Page Three
2. Residual handling and utilization/disposal scheme: Until 2001, residuals were disposed of by
landfilling as authorized by Permit No. WQ0002378. All residuals are now land applied
under the authority of Permit No. WQ0014213.
3. Treatment Plant Classification: Class IV (no change from previous rating).
4. SIC Code(s): 4952 Wastewater Code(s): 01 MTU Code(s): 02002
PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant Funds or are any public monies
involved (municipals only)? Public monies were used in the construction of this facility.
2. Special monitoring or limitations (including toxicity) requests:
3. Important SOC/JOC or Compliance Schedule dates: The Town is not under an SOC or JOC
nor is either being considered at this time.
PART IV - EVALUATION AND RECOMMENDATIONS
The Town of Mooresville requests renewal of the subject Permit. There are no physical
changes and/or modifications proposed at this facility during this renewal. At one point during the
term of the current permit, the Town considered an extension of the outfall line to possibility effect
an improvement to the Town's permitted effluent limitations. However, since that time this proposal
is no longer being considered.
The WWT facility is currently averaging approx. 50% of it's design capacity. This flow is
about 10% less than when one of the Town's major industrial wastewater customers (Burlington
Industries) shut down in 1999. Effluent quality (especially color) has significantly improved as
wastewater type becomes more domestic in nature.
The Town has estimated that I/I in the collection system amounts to = 0.200 MGD. The Town has
contracted with Black and Veetch to monitor the collection system for I/I, identify potential sources,
and make recommendations back to the Town of possible corrective measures. This collection
system study is to be completed in 2004.

Page Four
Pending receipt and approval of the draft permit, it is recommended that the NPDES Permit
for this facility be renewed.
