Footnotes:
1. The monthly average effluent BODs and total Suspended Residue concentrations shall not exceed 15% of
the respective influent value (85% removal).
2. Whole effluent toxicity will be evaluated using the Chronic Toxicity (Ceriodaphnia) P/F test at 9%.
The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

Permit NC0026913
A. (2.) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 9%.
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, 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: North Carolina Division of Water Quality
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.

Our office has received the draft permit for the subject facility. Upon review of
this draft, our office noted that Special Conditions A(2) contained different toxicity
testing months than the months contained in the facility's current permit. The facility's
quarterly toxicity months currently are March, June, September, and December. The
Special Condition (2) in this draft has them conducting toxicity testing during January,
April, July, and October. Our office recommends correcting the Special Condition page
to require toxicity testing to be conducted during March, June, September, and December.
Our offices believes that changing the toxicity testing schedule could create reporting
problems for this facility.
We appreciate your assistance to undertake the necessary steps to correct the
existing draft permit and incorporate the recommendation cited above. Please feel free to
contact me at 733-2136 if you have any questions.

BACKGROUND
The Town of Sparta WWTP is a Class III facility discharging into Little River, which is
classified as C waters. At the time of the last permitting cycle, the facility was permitted at 0.25
MGD and had received an Authorization to Construct (ATC) to expand the plant to
accommodate a flow of 0.60 MGD. This expansion was completed in 1996. In addition to the
expansion, a modified pretreatment program was developed to enable Sparta to accept flow from
Bristol Compressors, a metal finishing facility.
Instream Monitoring and Verification of Existing Conditions and DMR Data Review. This
facility discharges to Little River in the New River basin. The BOD and DO data from instream
monitoring indicate that the facility is in compliance with the NPDES permit. The DMRs further
confirm compliance with the permit since 1998. In 1997, the facility had problems with total
residual chlorine as well as one violation each of the cadmium and fecal coliform limits. The
total residual chlorine problem appears to have been fixed since.
Of the metals for which the facility must monitor through the NPDES permit, cadmium, copper,
chromium, mercury, zinc, and silver have all been detected in the effluent.
Correspondence: A review of the correspondence reveals that no NOVs have been issued since
1997. In 1997, NOVs were issued for three total residual chlorine violations, one cadmium
violation and one fecal coliform violation. The facility paid the associated fees and has not had
any NOVs or compliance problems since. All the inspection reports included in the
correspondence folder were fairly positive.
PERMITTING STRATEGY
Waste Load Allocation (WLA). The Division prepared the last WLA in 1995. The previous
and current effluent limits were based on guidelines and water quality standards using the
proposed new flow of 0.60 MGD and the inclusion of the SIU.
Fact Sheet
NPDES NC0026913 Renewal
Page 1

Reasonable potential analysis was performed on metals monitoring data from the facility
(including the monitoring data from the pretreatment unit). Reasonable potential for
contamination was demonstrated for cadmium, silver, selenium and mercury. The acute limit of
15 ug/L was assigned to cadmium and a new limit was imposed for selenium. The mercury limit
is already included in the permit. No reasonable potential was shown for chromium, lead, or
nickel so it is proposed that these monitoring requirements be removed from the permit. All of
these metals will continue to be monitored by pretreatment. No reasonable potential was
demonstrated for cyanide, so this requirement will be changed from a limited quantity to a
monitored quantity. Copper, zinc and silver will continue to be monitored in the NPDES permit.
A summary of the changes resulting from the reasonable potential analysis appear below:

Add acute limit of 20 ug/L to effluent page
All other metals limits or monitoring requirements that were included in the previous permit will

SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following changes will be incorporated into the permit:
• A new cadmium limit of 15 ug/L will be incorporated into the effluent limits page
• The cyanide limit will be changed to a twice monthly monitoring requirement (based on the facility
being a Class III)
• The chromium, lead and nickel monitoring requirements will be removed from the effluent limits
page (pretreatment will continue to monitor these).
• A selenium limit of 20ug/L will be added to the effluent limits page based upon reasonable potential.
Included in the cover letter will be a statement that once a year of data have been collected, the
reasonable potential analysis for selenium may be performed again (the current RPA is based on 5
data points from pretreatment)
• The permit limit for mercury and the twice -monthly monitoring requirements for copper, zinc, and
silver will remain in the permit.

Purpose of Visit: To view SBR system in operation
Conditions: Clear and sunny, 70s, light breeze
Overview: Walked through the facility w/ operator, to see how the plant is designed and operated,
and to discuss +/- of SBR process. On -site approx. 45 min.
Plant Description: The plant is located on a relatively steep hillside adjacent to the receiving stream. The
original extended air plant is located approx. 100 ft. upslope of the stream, and the new
SBR is cut into the hillside above the original plant.
Incoming wastewaters pass through a bar screen to the influent pump station, then up the
hill to a cast concrete flow splitter and energy dissipator box. Flow is split between the
SBR and extended air systems. The effluents share the same chlorination process and
outfall.
The SBR is designed by Aqua Aerobics consists of one 0.302 MG reactor tank (cost $
11 M) and one 0.220 MG effluent holding tank. The extended air plant is 0.250 MG.
The plant is permitted for 0.60 MGD and typically sees about 0.30 MGD at present.
BOD/TSS limits are 30/30.
Operations: The bar screen is of the manually cleaned type, in a channel deep enough to be
considered a confined space. Cleaning is labor intensive and a safety issue.
Headworks lack grit and scum removal, so both build up in the aeration basins.
The flow splitter was not adequately designed, so the operators have made some
changes to better control flows to the treatment units.
Operators have to be alert with the combined system. The extended air plant handles all
flows while the SBR is in react/decant modes; it is at or above its design limit in those
times. This is especially troublesome if the SBR is not able to treat and release on
schedule.
Operators have to be careful in releasing effluent from the SBR holding tank, because the
combined flow from the two systems is greater than the hydraulic capacity of the

chlorination channels. They originally had a problem with the effluent line?, which wanted
to siphon off the entire tank in rapid fashion.
Other Issues/Solutions: Walkways around the SBR tanks are not connected above ground, so operators must
climb down from one, then back up the other.
Key SBR tank components are not accessible from tank walkways. For instance, the
operator must launch a small boat to get to the surface aerator for maintenance.
Follow -Up: None required.

SLUDGE MANAGEMENT PLAN
June 15, 2000
The Town of Sparta has a 160,000 gallon digester where sludge is wasted on a daily basis and is held
for stabilization for a period of three months. It is then applied to farm land in
conjunction with land application of sludge permit # WQ0006242 by Synagro Corporation.
