Permit N000467w%
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia drabia 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 Tesi 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.

Summary
The facility has requested a permit renewal with no modifications. The facility indicated
that Burlington Industries, the largest industrial waste discharger, closed their
Mooresville facility effective July 01, 1999. The average flow from this facility was one
million two -hundred thousand gallons. In addition, Super Print Works was acquired by
PGI Nonwovens. Although the general printing operations will remain unchanged, the
discharge is anticipated to decrease by two hundred thousand gallons per day.
The following notes were taken during the review of the application package:
> Review of Basin Plan:
Dye Branch and the headwaters of the Rocky River are significantly impacted by
Mooresville's discharge, which has had frequent toxicity failures. Model results
indicate that Mooresville's permitted limits for oxygen -consuming wastes are
predicted to result in violations of the DO standard in the Rocky River.
However, during 1994-1996 Mooresville, on average, treated its wastewater to
well below its permitted limits and no DO violations were reported by the
facility during this period. The DO standard appears to be protected at
Mooresville's current level of treatment and waste flow. However, should the
facility wish to expand in the future, DWQ will review the limits and make
modifications where they are appropriate.

DENR/DWQ
FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES No. NC0046728
(Continued)
Mean fecal coliform levels in the upper Rocky River far exceed the standard and
turbidity violations occur frequently, indicating that nonpoint source inputs are
also a problem in this subbasin. Considerable growth is occurring in this area as
Charlotte metropolitan area expands eastward.
Additional activities and resources are needed to identify impairment sources and
to develop management strategies for this waterbody. As resources allow, DWQ
intends to develop NPS management strategies for this waterbody.
> 303(d) List Review
Reported problem parameter is sediment.
> Reasonable Potential Analysis:
A reasonable potential analysis was performed using the most recent DMR data.
The results of the analysis are attached to this document. In summary,
Cadmium The maximum predicted concentration was determined to
be less than the allowable concentration. Therefore, no limit will be
included in the renewal.
- Cyanide The maximum predicted concentration was determined to
be greater than the allowable concentration. Therefore, a limit of 5.0
µg/1 was be included in the renewal.
Lead The maximum predicted concentration was determined to be
greater than the allowable concentration. Therefore, a limit of 26.0
µg/1 was be included in the renewal
Nickel The maximum predicted concentration was determined to be
less than the allowable concentration. Therefore, no limit will be
included in the renewal.
- Selenium The maximum predicted concentration was determined to
be less than the allowable concentration. Therefore, no limit will be
included in the renewal.
Chromium The maximum predicted concentration was determined
to be less than the allowable concentration. Therefore, no limit will
be included in the renewal.
Copper Monitoring only for copper will be included in the permit.
This parameter has an action level of 7 µg/l.

•
DENR/DWQ
FACT SHEET FOR NPDES PERMIT DEVELOPMENT
NPDES No. NC0046728
(Continued)
- Arsenic The maximum predicted concentration was determined to
be less than the allowable concentration. Therefore, no limit will be
included in the renewal.
- Mercury The maximum predicted concentration was determined to
be less than the allowable concentration. Therefore, no limit will be
included in the renewal.
Zinc Monitoring only for zinc will be included in the permit. This
parameter has an action level of 50 µg/l.
The facility joined the Yadkin Pee -Dee River Basin Association in June of
1998. Therefore, the established instream monitoring requirements will be
waived until the facility chooses to terminate its membership with the
association.
• WLA Review:
The most recent WLA was prepared in December of 1993. Limits were
determined to be water quality limited and instream monitoring was
recommended for DO, Fecal Coliform, Temperature, and Conductivity. In
addition, the following metals monitoring requirements were recommended:
Cadmium weekly average limit of 2.0 µg/1, Cyanide weekly average limit of
5.0 µg/1; Nickel weekly average limit of 93 µg/1, lead weekly average limit of
26 µg/1, and Chromium weekly average limit of 52 µg/1.
> Staff Report Review
Most recent staff report was prepared in June of 1999. The WWPT appears
to be adequate to meet all existing effluent limits and is well maintained and
operated. The subject WWTP is a member of the Yadkin -Pee Dee River
Basin Association. As a member, all instream monitoring is conducted by
the association. However, influent and effluent sampling remains under the
control of the WWTP facility.
Region recommends that the permit be renewed as requested.

OFFICE OF THE TOWN MANAGER
Subject: Renewal of NPDES Permit NC0046728, Rocky River WWTP, Iredell County
Dear Mr. Weaver:
Following is the information requested to accompany our permit renewal package. I have also
included a synopsis of our anticipated flow decrease to begin late spring of this year.
Burlington Industries our largest industrial waste discharger announced the closing of their
Mooresville facility effective July 01, 1999. The dye ranges are scheduled to cease discharging in
late April of this year. The average flow per day from this facility was one million two -hundred
thousand gallons.
Superba Print Works, our next largest industrial waste discharger, was acquired by PGI
Nonwovens. Although the general printing operations will remain unchanged, the discharge is
anticipated to decrease by two hundred thousand gallons per day.
Our flow reported on the "Standard Form A" municipal application was three million twenty
thousand gallons. This was based on last years average and as you can see, this figure will
decrease by at least 47 percent.
Based on the above information and our record of compliance, I would like to respectfully submit
our application for renewal and to request some modifications to our sampling and analysis
requirements.
POST OFFICE BOX 878 • MOORESVILLE, NORTH CAROLINA 28115 • 704-663-3800 • FAX [phone]

The modifications requested would include decreased sampling for metals and cyanide, as the
two industries listed above were major contributors of these constituents. I would also request
decreased sampling for BOD from daily to three days a week as we have consistently met our
BOD limits. The last request would be to decrease our ammonia nitrogen sampling from daily to
weekly, as we have consistently shown our discharge of ammonia nitrogen to be less than one
milligram per liter.
If you have any questions or need to contact me, please feel free to call me at 704-662-8472.
Thanks for all your support in these matters.
Sincerely,
,c,,, ? LA, --
H. Carson Fisher
Town Engineer

Description of Management Practices
Town of Mooresville on Site Monofill
(1) The disposal site is not located in a fault or unstable area.
(2) Runoff is controlled by a system of silt fence and earthen barriers. Also after completing each
monofill area the site is leveled and seeded with a blend of fescue and millet.
(3) No crops are grown on the monofill area.
(4) No animals are allowed to graze on the monofill area.
(5) Each unit is covered daily with soil.
(6) Access is controlled by a combination of chain link and barbed wire fencing.
(7) The monofill site is inspected daily by the ORC or back up ORC.
(8) Each monofill area is bore tested prior to utilization
(9) Spills are prevented using a leak proof truck.
(10) Samples are analyzed daily in our lab for total solids, total volatile solids and PH.
(11) Quarterly samples are analyzed for metals, cyanide and arsenic.
(12) State Inspections are performed annually.
(13) A TCLP is performed annually.

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 currently causes a
discoloration of the receiving stream, however, this discoloration is expected to
diminish once a major dying operation has ceased operation (expected 7/99).
Downstream uses are primarily agriculture. Aquatic life (minnows) were observed
immediately below the discharge point.
PART H - 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: N/A
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: N/A
g.
Possible toxic impacts to surface waters: Chlorine is added to the waste stream.
The Town has passed toxicity tests performed under the terms of the Permit,
however, 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 residuals in the effluent.
h. Pretreatment Program (POTWs only): approved
2. Residual handling and utilization/disposal scheme: Residuals are disposed of by landfilling
as authorized by Permit No. WQ0002378 and by land application under Permit No.
WQ0014213.

5. 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: The Town has requested
that effluent sampling for metals and cyanide be reduced since the two (2) main
contributors of these constituents has ceased operation. In addition, a reduction in effluent
sampling for BOD from daily to 3 days per week and ammonia nitrogen sampling from
daily to weekly has been requested by the Town. Any reductions in the amount of
sampling for metals and cyanide should be dependant on a review of a revised headworks
analysis that is currently being prepared by the Town. As for any reductions in effluent
sampling for BOD or NH3 as N, it is unlikely that the Division will find sufficient
justification for such a reduction, however, P&E should evaluate this request nonetheless.
3. Important SOC/JOC or Compliance Schedule dates: N/A
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 proposed an extension of the outfall Iine to possibility effect
an improvement to the Town's permittted effluent limitations. However, since that time this
proposal is no longer being considered.
The WWT facility is currently averaging approx. 62% of it's design capacity, however,
daily flows are expected to significantly decrease once flows from two (2) major industrial
customers are reduced/eliminated. One of these industries is Burlington Industries (BI), which up
till now generated 40% of the Town's total hydraulic flow. BI has announced that the
Mooresville Plant will close the entire plant in July of this year. BI has already closed the Plant's
dying and bleaching operation (effective 4/99). Effluent quality (especially color) has recently
improved as wastewater type becomes more domestic in nature. There is also information
provided in the renewal application of a second industrial discharger (PGI Nowovens) reducing
their flow by 0.200 MGD.
