Quarterly samples for monitored parameters shall coincide with the chronic toxicity test.

Permit Na. NCO085871
A. (2) CHRONIC TOXICJTY PASS/FAIL PERMIT LIMIT (Quarterly)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at aneffluent concentration of 4.5 %.
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 March, June, September, and December. 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. If reporting pass/fail results using the parameter code
TGP3B, DWQ Form AT-1 (original) is sent to the below address. If reporting Chronic Value results using the
parameter code THP311, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: NC DENR / Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
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.
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 Section 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.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such monitoring shall
be included in the calculation and reporting of the data submitted on the DMR and all AT Forms submitted.
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.

Background and Summary
Flakt Products manufacturing ceased operation in 1986. The site is vacant and the
contamination resulted from metal fabrication activities and the use of solvents at two
degreasing baths and a 7000 gallon above ground storage tank. Site assessments showed that
trichlororethene and/or 1,1,1—trichloroethane were released at some time during the
operation of the facility. In -situ volatilization was used to remediate soil. Soil clean-up
ceased in 1/93 when VOC concentrations of soil were reduced below specified cleanup
concentrations.
In 11/97 an ATC was issued to address the groundwater contamination. The proposed
treatment system consisted of about 60 extraction wells, iron sequestering (citric acid) feed
pump, 1000 gallon equalization tank, transfer pump, air stripper, bag filters, granular
activated carbon filters, flow monitoring device, and a 1500 foot outfall. The bag and GAC
filters were to be installed if the effluent failed to meet TSS or toxicity permit limits. The
consultants at MACTEC do not believe the filters were ever needed. The current system
consists of 7 extraction wells, iron sequestering, equalization and high pressure air strippers.
Records document that the original permit was issued in January 1997 and the groundwater
treatment facility started operation in 7/98. A modification request was received in 1998 to
increase flow from 0.0288 MGD to 0.0864 MGD. The permit was renewed in August 1999
with the increase in flow as requested and an expiration date of 5/31/04. The facility asked to

NPDES PERMIT FACT SHEET
Page 2
NPDES No. NCO085871
have the monitoring frequency reduced and in 1/2000 a new Effluent Limitations and
Monitoring page was issued reducing all parameter monitoring from monthly to quarterly.
Flow remained as a continuous recording, influent or effluent. The permit was renewed
again in June 2004 with an expiration date of May 31, 2009. No changes were made to the
permit except in the wording of the Chronic Toxicity Permit Page, Section A. (2.).
The facility discharges to Brushy Fork, a Class C stream, in the Yadkin -Pee Dee River Basin. Brushy
Fork is not on the 303(d) list for impaired streams. Brushy Fork has a 7Q10 flow of 2.9 cfs and joins with
Salem Creek approximately 1,500-ft downstream.
DMR Data, Compliance and Permit Developement
Initial samples taken during the first year of remediation detected the following parameters in the waste -
stream: 1,1-dichloroethene, zinc, copper, lead and iron. FeREMEDE, a non -toxic iron -sequestering agent
is currently used to reduce iron coagulation and clogging. This facility is not subject to any Categorical
Effluent Guideline Limitations but is subject to the DENR, Division of Waste Management, Superfund
Section, Inactive Hazardous Sites Branch, Implementation Guidance published in August 2008. This
means the facility must meet "Remediation Goals for Groundwater" which are essentially safe drinking
water standards before it can stop the remediation process. VOC's must be monitored by the facility as
part of this requirement.
A compliance inspection was performed on March 12, 2008 by Winston-Salem Regional personnel and
operations & maintenance, record keeping, monitoring, site review and flow measurement were all found
to be satisfactory.
The only parameter limited in the permit is TSS with a daily maximum of 30 mg/L. TSS has been below
detectable levels for the last five years.
Chronic Toxicity
• Since its initial operation in 7/98 the facility has consistently passed its toxicity limit with only one
exception. One NOV was issued during the first permit cycle for a toxicity violation in 1999. It is
recommended that chronic toxicity sampling remain in the permit.
Metals and RPA
A review of the last two permit cycles, Aug. 1999 through March 2009, show the maximum
concentration of all detected metals never exceeded standards or action levels. Metals detected
during the previous permit cycles included zinc, copper, lead, manganese and iron. DMR's reviewed
for the most recent permit cycle found only copper and manganese in detectable levels. All other
metals, arsenic, iron, lead, and zinc, were below detection levels for five years. There is no
reasonable potential for a metals violation for As, Fe, Pb or Zn. It is recommended that monitoring
for these metals be removed from the permit.
A Reasonable Potential Analysis performed on copper and manganese resulted in maximum
predicted levels of 0.0002 ug/L for Cu and 0.05 ug/L for Mn (see RPA attached). Therefore, copper
and manganese have no reasonable potential for a standards violation and should be removed from
the permit. The only water quality based standard for manganese is for a water supply classified
stream which has a limit of 200 ug/L. Brushy Fork is not a water supply classified stream but the
RPA shows manganese has no potential to violate this standard.
Organics
• No organic contaminants have been detected in effluent samples (below detection levels) taken since
Aug. 1999. Quarterly monitoring for particular organics should remain in the permit due to the
nature of the discharge.

Miscellaneous Comments
oAJ
YES_ This is a SIMPLE EXPEDITED permit renewal (administrative
renewal with no changes, or only minor changes such as TRC, NH3,
name/ownership changes). Include conventional WTPs in this group.
YES_ This is a MORE COMPLEX EXPEDITED permit renewal (includes
Special Conditions (such as EAA, Wastewater Management Plan), 303(d)
listed, toxicity testing, instream monitoring, compliance concerns, phased
limits). Basin Coordinator to make case -by -case decision.
YES_ This permit CANNOT BE EXPEDITED for one of the following reasons:
• Major Facility (municipal/industrial)
• Minor Municipals with pretreatment program
• Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS,
etc)
• is based o�reas�onab�le otential analysis (metals, GW remediation organics
• Permitted flow > 0.5 MGD (requires fulf FactSheet)
• Permits determined by Basin Coordinator to be outside expedited process
