• • Part III Permit No. NC0026913
G. CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 9% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from the effective date
of this permit 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.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re -opened and modified to include altemate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.

Facility Name Sparta WWTP Permit # NC0026913 _ Pipe # 001 _
CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is 2.1 % (defined as treatment two in the North Carolina procedure document). The permit holder shall
perform quarterly monitoring using this procedure to establish compliance with the permit condition. The first
test will be performed after thirty days from the effective date of this permit during the months of
_MAR JUN SEP DEC Effluent sampling for this testing shall be performed at the NPDES permitted final effluent
discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management 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 and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

Facility requesting renewal of existing NPDES permit @ 0.250 MGD with modification for
expansion to 0.6 MGD. The receiving stream is located upstream of a designated HQW
segment of the South Fork New River. Expansion modification first requested in 1994 for
the addition of flow from a new industry, Bristol Compressors, manufacturers of air
conditioning and refrigerator compressors. Limits and monitoring requirements for several
metals that could be discharged were added to the permit at that time. No oxygen
consuming problems are present with this discharger. NH3 toxicity limits of 9 and 27 mg/1
have been given at the expansion flow of 0.6 MGD, however new procedure for NH3
limits, limits greater than 25 mg/1 will not be given will recommend monitoring .
Staff report indicates that construction of additional treatment facilities: Sequential Batch
Reactor (SBR), Flow Equalization Basin, Splitter Box to SBR or extended air unit and
enlargement of the chlorine contact chamber, should be completed by Dec. '95. Sparta
currently under SOC for flow (instream assessment finalized 4/94) and toxicity (SOC
amended 7/94).
WSRO requests that monitoring for metals be continued but no limits until
six (6) months after the upgrade of the plant is complete. Current permit @
0.600 MGD would limit cadmium = 23 µg/l, Cyanide = 58 µg/I, and
Mercury = 0.2 µg/l, w/ monitoring for Cr, Cu, Ni, Pb, Zn, As, and Ag.
This request is apparently to give Sparta time to determine the level of treatment needed to
meet the new metal limits. Tox analysis done at 0.250 MGD and 0.6 MGD, with facility
not at full capacity for Bristol Compressors, not sure that this data is representative of what
effluent will be like with all industrial flow. Will renew existing metals limits and
monitoring: will request that limits not go into effect until 6 months after
issuance of the permit. This to insure that enough data will be available
upon next renewal.
7/11/95 - Conference w/ Bo McMinn of Pretreatment.
Sparta has a very old activated sludge plant wl I&I problems. Construction of new plant
has been delayed by the weather and Town is missing deadlines under the SOC. In
addition, pretreatment and WSRO have concerns about whether the one SBR will provide
sufficient treatment. May need more than one SBR, if the cell should become full, while
the other cell is treating WW. Bristol has sent a couple of slugs of WW to the plant and has
knocked out the plant both times. Sparta is under a modified or short term plan which will
not collect enough data for analysis at next permit renewal, if it is the only source of data
monitoring.
With concerns about Sparta completing construction on time and
questions about the treatment of the new plant, he recommends: 1) keeping
limits for 0.6 MGD the same, 2) adding monitoring for metals @ 0.250
MGD with the exception of arsenic monitoring which he feels can be
dropped at both flows.
Concur with Bo's recommendations, had already discussed with
Carla about renewing all limits and monitoring @ 0.6 MGD. Will add
metals monitoring @ 0.250 MGD. Will drop arsenic monitoring.

Facility Name Sparta WWTP Permit # NC0026913 _ Pipe # 001 —
CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality
is 9 % (defined as treatment two in the North Carolina procedure document). The permit holder shall
perform quarterly monitoring using this procedure to establish compliance with the permit condition. The first
test will be performed after thirty days from the effective date of this permit during the months of
_MAR JUN SEP DEC . Effluent sampling for this testing shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management 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 and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.

4. Alternative Analysis Evaluation: Has the facility evaluated
all of the non -discharge options available. Please provide
regional perspective for each option evaluated.
Spray Irrigation: Not enough land
Connection to Regional Sewer System: N/A
Subsurface: N/A
Other disposal options: N/A
5. Other Special Items:
With the addition of Bristol Compressors, the Sparta WWTP
has has trouble producing a quality effluent. The WWTP was
operating near capacity when Bristol was added and the Town
requested an SOC for the additional flow.
Upgrade on the Sparta WWTP should begin soon. It is the
concern of this office that with the addition of Bristol
Compressors and any future expansion by the Town that only one
Sequential Batch Reactor (SBR) with one equalization basin will
not adequately handle the incoming waste.
The WWTP discharges into the Little River which flows to the
New River. Both rivers are classified HQW downstream from the
discharge point. Appropriate steps should be taken by the Town
of Sparta during the upgrade to protect these waters.
Recommend permit be reissued.

.0004 DEF1NRIONS
The folk: wing definitions shad apply throughout thb Subchapter.
(1) Activated Carbon Beds. A physkaVchemical method for reducing soluble organic madettal from wastewater effluent; The column -type beds used In this
method will have a flow rate varying trout two to eight gallons per minute per square foot and may be either upfbw or downfbw carbon beds. Carbon may or
may not be regenerated on the wastewater treatment plant site;
(2) Aerated Lagoons. A basin in which all solids are maintained in suspension and by which blobgkwl oxidation or organic matter ins reduced through artifiically
accelerated transfer of oxygen on a flow -through bask;
(3) Aeration A process of bringing about intimate contact between air or Ngh purity oxygen in a liquid by spraying. agitation or dMuslon;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention tine of 18 hours.
(4) Agriculturally managed site. Any she on which a crop is produced. managed. and harvested (Crop includes grasses. grafts. trees. etc.):
(5) Air Stripping. A process by which the ammonium ion k first converted to dissolved ammonia (pH adjustment) whh the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as benzene. toluene. and xybns;
(�Carbon ration. The regenbratbn of exhausted carbon by the use of a furnace to provide extremely Ngh temperatures which volatilize and oxidize the
Carbonaceous Stags. A stage of wastewater treatment designed to achieve 'secondary *Murat 1mdts;
(7) Centrifuge. A mechanical device In which centrifugal force is used to separate solids from liquids or to separate Liquids of different densides:
(e) Chemical Addition Systems- The addition of chemk at(s) to wastewater at an application point for purposes of improving solids removal. pH adjustment.
alkalinity cordrol. etc.; the capability to experiment with different chemicals and different application points to achieve a specific result will be considered one
system; the capability to add chemicals) to dual units will be rated as one system; capability to add a chemical at a different application points for different
purposes will result in the systems being rated as separate systems;
(10) Chemical Sludge Conditioning. The addition of a chemical compound such as Ilms. Ionic chloride. or *polymer to wet sludge to coalesce the mass prior to
s application to a dewatering device;
(11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing korganic. non -toxic materials from sand. gravel.
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping fadthies or any other appurtenances;
(12) Combined Removal of Carbonaceous SOD and Nitrogenous Removal by Nitrtfkalbn• A single stage system required to achieve permit effluent limits on SOD
and ammonia nitrogen within the same biological reactor;
(13) Dechbrinatbn. The partial or complete reduction of residual cNorfns M a liquid by any chemical or physical process;
(14) Dsnbrfficatbn Process. Tie conversion of nbrats-nbrogen to nitrogen gas;
