SPECIAL CONDITIONS
A (3). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) @ Rocky River
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 4.6%.
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.
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: Environmental Sciences Branch
North Carolina Division of Water Quality
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.

• No portions of the Rocky River lie within sub -basin 03-07-13. Outfall 002 falls within
sub -basin 03-07-14. Outfall 001 has been properly characterized as being within sub -
basin 03-07-13.
• Expiration date changed to January 31, 2009.
• Remove silver monitoring requirements due to lack of reasonable potential to exceed
instream standards.
• Remove lead limit and monitoring requirements at Rocky River discharge location
(Outfall 002) due to the lack of reasonable potential to exceed instream standards.
• A weekly average ammonia limit will be added as required by the 2002 NH3N policy.
The weekly average limits at the Rocky River location will be 9 mg/L (summer) and 18.0
mg/L (winter). The limits at the Long Creek location will be 8.4 mg/L (summer) 18.0
mg/L (winter).
2.0 Summary
The town of Oakboro has requested renewal of the existing permit. While the facility is currently
permitted for 0.9 MGD, some upgrades were recently completed allowing the facility to
accommodate a design flow of 1.2 MGD. Oakboro is now a regional facility, serving the Town of
Oakboro, Town of Stanfield, Town of Red Cross, City of Locust and the Ridgecrest area.
Oakboro's pretreatment program has been inactive since 2001, and none of its tributary
communities have pretreatment programs.
Upon recent completion of its expansion, the Oakboro WWTP now has two outfall lines (001 and
002) deriving from the same treatment process. Line 001 to Long Creek is an emergency outfall
that would only be used if the pump station to Rocky River fails (outfall 002). The outfalls cannot
be used concurrently. The valve that controls outfall 001 is kept secured to avoid accidental
discharge to Long Creek. Neither Long Creek nor the Rocky River are 303 (d) listed.

NPDES Permit Fact Sheet - 12/30/03 Town of Oakboro WWTP
Page 2 NC0043532
The town of Oakboro is a member of the Yadkin Pee -Dee River Basin Association and is therefore
not required to perform instream monitoring. There are YPDRBA monitoring stations both
upstream and downstream of the Long Creek outfall and a DWQ ambient monitoring station
approximately 10 miles downstream of the Rocky River discharge. A 1994 WLA recommends
downstream monitoring approximately 1.7 miles downstream (at the end of SR 1659) for DO,
fecal, temperature, and conductivity, however this may not be necessary due to the low IWC
(4.6% on Rocky River)
Note: In 1993, a QUAL2E model was performed on Rocky River and Mallard Creek to assist with
the management of wastewater discharge issued in the upper watershed of the Rocky River. It
was recommended that no new or expanded discharges be permitted in the study area unless an
evaluation of engineering alternative shows that it is the environmentally sound alterative. If
new or expanded discharges are permitted, they will receive BAT technology limits in the
watersheds above the confluence of Mallard Creek and the Rocky River, due to severely limited
assimilative capacity. Any new or expanding discharge in the lower watersheds of the Rocky
River should receive a total BODu(CBOD + NBOD) limit of 32 mg/L or less, equivalent to 10
mg/L BOD5 and 4 mg/L NH3 for typical domestic discharges. This level of treatment will
protect the DO standard as well as preventing any one discharge from exhausting 100% of the
available assimilative capacity of the river.
3.0 Compliance Summary
WET Testing Results
Oakboro performs quarterly WET testing. Until July, 2001 the tests were performed at an effluent
concentration of 19% characterizing the Long Creek discharge at 0.5 MGD. Currently, tests are
conducted at an effluent concentration of 4.6% to represent the 0.9 MGD discharge to Rocky
River. Since January, 2001 the facility has passed 12 of its 13 toxicity tests. The only failure was
in July, 2002. An NOV reports that action levels for both copper and zinc were exceeded.
Correspondence File Review
There were no recurrent problems or deficiencies noted in the correspondence files. From the
period of January 2001 to October 2003, Oakboro received three NOVs. The first was due to their
July 2002 WET test failure; the second was issued in February 2003 for exceeding the lead limit
(reported value 110 pg/L); and the third was issued in November 2003 for BOD weekly and
monthly average limit violations. The reported weekly average was 15.1 mg/L and the monthly
average was 11.7 mg/L. The town received civil penalty assessments for both limit exceedances
totaling $1170.49.

Generally, Oakboro's effluent values fall well within the boundaries of its permit limits. Its
highest monthly average flow is 0.49 MGD, which would put the facility at 50% capacity. Its

,NPDES Permit Fact Sheet — 12/30/03 Town of Oakboro WWTP
Page 3 NC0043532
average monthly flow is 0.27 MGD. The only parameters to have exceeded permitted limits are
BOD and NH3N. In both September and October of 2003, the permittee exceeded its summer
average monthly BOD limit of 9.0 mg/L. Reported values were 11.7 mg/L and 10.7 mg/L,
respectively. Ammonia limits were violated in early 2001 and, more recently, October 2003. The
permittee reported monthly averages of 9.4 mg/L for January, 2001 and 6.94 mg/L in February,
2001 (violating the 6.0 mg/L monthly average winter limit), and 3.70 mg/L in October, 2003
(violating the 3.0 mg/L summer limit).
Reasonable Potential Analysis
RPAs were performed for copper, silver, and lead using January 2001 through October 2003 DMR
data. Analyses were completed for both Rocky River and Long Creek. Since both outfalls receive
effluent from the same waste -stream, the same DMR data was used for analyses at both locations.
Results of the RPAs are as follows:
• Monitoring data showed reasonable potential for the discharge to exceed the copper
water quality standard. Since copper is an action level parameter the permittee will not
receive a limit unless it fails WET tests and copper is identified as the cause. The twice -
monthly monitoring requirement will remain in the permit for both the Long Creek and
Rocky River outfalls..
• Monitoring data showed no reasonable potential for the discharge to exceed the silver
water quality standards in either Rocky River or Long Creek. 62 effluent values (sampled
during 31 months from 2001 to 2003) were below the detection level (2.0 pg/L).
• Monitoring data showed no reasonable potential for the discharge to exceed lead water
quality standards on Rocky River. The limit and monitoring requirements will be
removed at outfall 002. However, the data does demonstrate reasonable potential to
exceed lead standards on Long Creek. This discharge location will receive a limit at the
'fZ FAV of 33.8 pg/L as well as a weekly monitoring frequency (effective when the
discharge is in operation).

Hi John,
Oakboro did have a chr limit of 19% in the last permit to
characterize their 0.5 MGD discharge to Long Creek. In this
renewal I'm permitting them for 0.9 MGD, which gives them a 29.71%
IWC (Long creek summer 7Q10 is 3.3 cfs). Let me know if this is
ok.
Thanks,

NOTICE OF VIOLATION
Whole Effluent Toxicity (WET) Testing
Copper and Zinc Action Level Policy
NPDES Permit No. NC0043532/002
Town of Oakboro WWTP
Stanly County
This is to inform you that a review of your toxicity self -monitoring report form for the month of
July 2002 indicates a violation of the toxicity limitation specified in your NPDES Permit. You should
undertake necessary actions to eliminate or reduce effluent toxicity to acceptable levels.
In addition, this correspondence contains important information on the Division's Copper and
Zinc Action Level Policy which is triggered by two or more toxicity limit violations that occur during
the toxicity testing calendar quarter specified by the toxicity testing special condition of your NPDES
Permit. Attachments addressing policy implementation and a copy of the Division's Toxicity Reduction
Guidance have been included with this Notice of Violation.
You should initiate follow-up toxicity testing upon a single WET test failure which occurs
during the toxicity testing calendar quarter.
Your facility is currently monitoring for copper and/or zinc and is exceeding the action level for
these parameters. The policy states that whenever a facility experiences two or more toxicity limit
violations during a toxicity testing calendar quarter, the NPDES Permit will be modified to include
numeric limits for copper and/or zinc UNLESS the permittee provides one or more of the following:
1. Instream measurements of dissolved metal during low flow conditions that demonstrate
compliance with the Action Level standard
2. A revision of the prospective permit limit using improved inputs that in concert with
existing or additional monitoring data demonstrates compliance with the Action Level
standard
3. Toxicity Identification Evaluation ('17E) results that definitively rule out copper and/or zinc
as causes of effluent toxicity
4. Demonstration by an alternative method approved by the Division and EPA that copper
and/or zinc is not the cause of toxicity

2,
i 4
The Division has evaluated your copper and/or zinc monitoring data. The Division has also
developed a prospective NPDES permit limit based on your facility's instream waste concentration, the
copper and/or zinc action level criterion and a translator procedure. Based on this data your prospective
copper permit limit is 327 pg/L.
The permittee, upon experiencing two or more toxicity limit violations during a toxicity'
testing calendar quarter must either provide DWQ with:
a) Written notification indicating acceptance of the prospective copper
and/or zinc permit limit. Notification is due within 30 days after the date of
the second WET Notice of Violation.
OR
b) Written notification indicating your choice of option(s) as noted on page
one of this correspondence. Notification is due within 30 days after the date
of the second WET Notice of Violation. DWQ approval of options 1-3
(previous page) is not necessary as the Division expects work to rule out
copper and/or zinc as causative effluent toxicants to begin immediately upon
the second WET permit limit violation.
Written notification (a or b above) shall be sent to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Please note that if you choose item b) above, you will be given nine months to submit
documentation that eliminates copper and/or zinc as causative effluent toxicants. Your final report
should be comprehensive and include all data used to support your conclusion(s). Should the data
indicate copper and/or zinc as the source of effluent toxicity or if the data are inconclusive as to copper
and/or zinc's role as a toxicity source, then the NPDES Permit will be reopened and the metal limits
specified above will be applied to the permit. The report is due nine months after the date of the second
WET Notice of Violation.
Three copies of the final report shall be submitted to:
North Carolina Division of Water Quality
Environmental Sciences Branch
Aquatic Toxicology Unit
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
You should consider submitting the above correspondence certified mail.
Failure to notify DWQ of your acceptance of a copper and/or zinc limit, failure to notify
DWQ of your option selection or failure to make acceptable demonstration to DWQ that copper
and/or zinc are not causative effluent toxicants within the stated time frames will result in
reopening of the NPDES Permit to include copper and/or zinc numeric limitations, as appropriate.
Please note that your actions to notify DWQ of prospective limit acceptance or to notify DWQ
of plan option(s) and subsequent submission of a plan are contingent upon two or more toxicity NPDES
permit limit violations occurring during a toxicity testing calendar quarter.

3
If the effluent is toxic, then we expect work to commence immediately with toxic effluent
samples. Failure to initiate work with toxic effluent samples during the study period is unacceptable and
will be considered a failure to make acceptable demonstration as cited above. We recommend a
minimum of three separate sampling events during the nine month period to definitively rule out copper
and/or zinc as causative effluent toxicants.
Also note that the WET limit will remain in your NPDES permit regardless of whether metals
are the source of effluent toxicity. The data resulting from your actions to disprove copper and/or zinc as
sources of effluent toxicity will determine whether NPDES Permit limits will be assigned for these
parameters. You are responsible for initiating actions to address these issues.
You may consider entering into a Special Order by Consent (SOC) with DWQ. A SOC provides
regulatory relief for specific NPDES permit limit violations and, if signed, will contain a requirement to
conduct a Toxicity Reduction Evaluation. The SOC will contain a compliance schedule, stipulated
penalties for failing to meet milestone activity dates and may contain upfront penalties to settle past
permit limit violations.
Additional information regarding the Division's copper and/or zinc action level policy can be
found at the following web site - http:/ /www.esb.enr.state.nc.us. Click on the "Aquatic
Toxicology" Unit and go to the prompt "DOWNLOADS" located at the bottom of the page. This web
site also contains EPA's "Toxicity Reduction Evaluation Guidance for Municipal Wastewater Treatment
Plants." Section 4 of this document contains pertinent information on Toxicity Identification
Evaluations.

Subject: Request for NPDES Permit Renewal
NPDES Permit NC0043532
Oakboro WWTP
Stanly County
Dear Mrs. Stephens,
c'DCP, ti — 83B
This letter is to respectfully request "renewal of permit" for Oakboro WWTP. The following is an update of changes
made to the above -mentioned facility since the last permit renewal.
• We have completed the expansion of the WWTP to receive a permitted flow of 0.9 MGD and design flow of 1.2
MGD.
• We have lost our one and only SIU, so we are no longer participating in the North Carolina Pretreatment Program.
• We are now a "regional" system serving the Town of Oakboro, Town of Stanfield, Town of Red Cross, City of
Locust, and the Ridgecrest area.
• Upon completion of the expansion, we now have two outfall lines (001 and 002) but these outfall lines are from the
same waste stream and derive from the same treatment methods. Only one outfall line may be used at any time due
to the method constructed. Outfall line 001 (to Long Creek) is an emergency outfall line only. In the event the
effluent pump station fails (Outfall 002), it would be opened, causing us to revert to the permit affecting Long Creek.
Otherwise our effluent is discharged to Rocky River. Since completion of construction of effluent pump station we
have not had to divert flow to Long Creek. The valve controlling Outfall 001 is kept secured to avoid an accidental
release of flow to Long Creek.
• The Town of Oakboro is a member in good standing with the Yadkin Pee Dee River Basin Association (YPDRBA),
in which they, for the last two years, have conducted the required monitoring of the receiving streams (Rocky River
& Long Creek). I have enclosed to you a copy of the signature sheet of the Memorandum of Agreement (MOA) for
continuation of study through 2008.
• As per the instructions for chronic toxicity in the renewal package, we have begun conducting extended testing to
include the Fathead minnow as our second specimen. We collected for chronic toxicity in July 2003 and we are

Richard/Claude - this permit was issued with phased limits before those
limits could be added to BIMS. It also included limits for an outfall
relocation.
To fix the problems with this permit I created outfall 002 and made its
limits effective 7/1/2001. The old 0.5 MGD outfall 001 has all its
limits expire 6/30/2001. These dates were chosen based on
correspondence from the permittee notifying us when the outfall
relocation/expansion operations were completed.
Richard - this chould fix the DO limit problem you asked me to correct.
Claude - currently both outfalls are tagged with "Active Discharge". I
wasn't sure what would happen if I made outfall 001 inactive (as it
currently is). Would making 001 inactive delete the waterbody record
from the outfall?

Subject: Town of Oakboro WWTP NPDES No. NC0043532. Request for adjustment.
Dear Mr. Goodrich:
On January 10, 2002 this facility was inspected by Mr. Wes Bell of the Mooresville Regional Office of
NCDENR, Water Quality Section. While discussing the plant's current performance Mr. Bell suggested
that I write and request an adjustment of our current permit. We here at the Town of Oakboro Wastewater
Treatment Facility operate on a tiered permit. We hay two (02) outfall lines, serial numbers 001 (Long
Creek) and 002 (Rocky River). At the conclusion of our WWTP expansion we transferred our discharge to
Rocky River. (See Encl.). Soon after the completion of the expansion, we suffered the loss of our one
industrial user, severing our effluent flow by as much as 65%. ( See Encl.)
Due to the expansion, loss of our SIU, and the severe reduction of flow we have essentially secured half of
the WWTP, reducing electrical consumption, wear on the unneeded equipment, and frankly we do not have
the necessary flow to warrant the newly installed equipment. I have enclosed a copy of the tiered permit for
your review (See Encl.). If you will notice we have a permit for 0.5 MGD to Rocky River. We are
currently following the 0.9 MGD to Rocky River permit. We have not recorded a monthly average flow in
excess of 0.35 MGD since September 2000. After speaking with the Utility Director and Mayor of Oakboro
they have expressed that we should not expect a reasonable increase in population or industrial users for
approximately three to five years.
Mr. Goodrich, I am respectfully requesting that this facility be allowed to operate under the 0.5 MGD via
outfall 002 (Rocky River) permit until the effluent flows increases to where our average monthly flow
exceeds 0.5 MGD. At which time we will immediately shift to the 0.9 MGD permit already in place.
The effect that this alteration will make will be minimal in reference to the receiving stream, but will
benefit this facility greatly. By changing permits we will be able to drop Total Residual Chlorine. This test
is very expensive to conduct. The daily cost of this test is averaging $3.17 per test. We will be reinstating
the Conductivity analysis, but will be reducing the Chronic Toxicity P/F from 4.6% to 2.6%. We will also
be required to maintain greater than 6.0 mg/L Dissolved Oxygen in our effluent rather than the 5.0 mg/L in
our current permit limitations.
Thank you in advance for your assistance in this matter, and we appreciate your time in reviewing our
request. If you require any further information, please do not hesitate to call me at 704.485.4613.

Re: Town of Oakboro WWTP Expansion
Permit No. NC0043532
Dear Mr. Goodrich:
Enclosed you will find a letter from Engineering Service, PA addressed to your attention in
regards to the completion of expansion and testing of the equipment. Please accept this letter as
notification of this wastewater treatment facility being now a 0.9 MGD discharging to Rocky
River. We have transferred our permits to reflect the change, and now operate as required. The
changes are as follows;
New limits on BOD ( 9.0 mg/1— summer / 18.0 mg/1 winter)
New limits on NH3 as N (3.0 mg/1— summer / 6.0 mg/I winter)
Dissolved oxygen limit reduced to 5.0 mg/I ( reduced from 6.0 mg/1)
Total Residual Chlorine limit reduced to 28 ug/1 ( no prior limit)
Lead limit is now 33.8 ug/I ( no prior limit)
Chronic Toxicity P/F at 4.6% ( reduced from 19%)
If you have any further questions or comments about this permit or completion, please don't
hesitate to call me at 704.485.4613. Thank you for your attention in this matter.

Town of Oakboro (NPDES # NC0043532)
Stanly County
Dear Mr. Branch:
O
LC)
The Pretreatment Unit of the Division of Water Quality has reviewed the request to drop the
following Industries from the list of significant industrial users (Sills) for the Town of Oakboro.
This drop request was received by the Division on February 5, 2001.
SIU Name
IUP Number
Stanly Knitting Mills.
0001
The review indicates that the SIU has ceased operation. Therefore, the SIU drop request is
approved based on compliance with 15 NCAC 2H .0907(c) and .0903(b)(34). Therefore, the
SIU list which is part of your approved pretreatment program is hereby modified.
Your request to inactivate your pretreatment program is also approved, since you no longer
accept wastewater from any S1Us. If an industry meeting the SIU definition proposes to
discharge to your WWTP, you must notify the Division, reactivate your pretreatment program,
and update pretreatment program elements according to current requirements.
Please note our new mailing address and fax number at the bottom of this page. Thank you for
your continued cooperation with the pretreatment program. If you have any questions or
comments, please contact Dana Rees Folley of the Pretreatment Unit at [phone] (ext.
523) [email: [e-mail]], or Tom S. Poe (ext. 522), Supervisor of the Pretreatment
Unit_
