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 _810 % (defined as treatment two in the North Carolina procedure document). The permit holder shall
perform quarter/y 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.

This office has received a copy of the proposed Special Order by Consent EMC
WQ 93-13 AD and offers the following comments. Due to the nature of the additional
industrial wastewater to be added to the system, the fact that no toxicity data exists for the
Town, and the incorporation of permit limitations for several metals with additional metals
monitoring, we would prefer to have seen either a quarterly full range chronic test or a
monthly pass/fail testing requirement in the Special Order. This point was discussed with
the modelers and with staff from the Winston- Salem Regional Office. We will, however,
concur with Attachment B, as proposed, which requires quarterly chronic monitoring at 6%
and also requires an increase in monitoring frequency to monthly upon any single quarterly
toxicity test failure.
Should you have any questions, please feel free to contact me at 2136.

SUBJECT: Instream Assessment for SOC 67b Request
Town of Sparta
NPDES Permit No. NC0026913
Alleghany County
Summary and Recommendations
The Technical Support Branch has completed an amendment to the instream
assessment completed October 22, 1993 for the Town of Sparta. The initial SOC request
was for inflow/infiltration problems and additional domestic wastewater from single family
homes. The current request is for domestic and industrial wasteflow to be added during the
SOC. The design flow of the Sparta plant is 0.250 MGD. The total SOC flow requested is
0.125 MGD, this includes 0.025 MGD of domestic and 0.100 MGD of industrial
wasteflow for a post-SOC flow total of 0.375 MGD, .
The results of the previous Level B model analysis indicated that the predicted
dissolved oxygen (DO) concentration was not significantly affected by the additional flow.
The EMC 67(b) criteria, which states that the discharge will not increase the DO minimum
by more than 0.5 mg/1 and will not extend the streamlength of the DO minimum by more
than 0.5 miles, was maintained with the additional SOC flow.
Regarding the industrial flow requested to be added to the facility during the period
of the SOC, additional monitoring requirements for metals and other toxicants should be
added to insure that water quality violations do not occur during this period. Preliminary
information provided regarding the proposed industrial wasteflow indicates that NPDES
permit limitations for the following metals will be needed :
Cadmium 36 µg/1
Cyanide 90 µg/1
Mercury 0.2 µg/1
Upon commencement of operation of the proposed industrial facility, monthly monitoring
for cadmium, cyanide, mercury, chromium, copper, nickel, lead, zinc, silver and arsenic is
also recommended. The Instream Assessment Unit also recommends implementation of
chronic toxicity monitoring on a quarterly basis upon commencement of operation of the
proposed industrial facility during the life of the Order. Language should be developed and
incorporated into the SOC to address these concerns.

Instream Assessment for Sparta SOC
- page 2-
Analysis and Discussion
An instream assessment was performed using the Level B model framework. The
design flow of the Sparta plant is 0.250 MGD. The pre-SOC flow used is 0.237 MGD,
however, the facility still has problems with inflow/infiltration. Wasteflow in the plant has
reached amounts of 0.430 to 0.800 MGD. The post-SOC flow used is 0.375 MGD, this
allows for the additional 25,000 GPD of domestic flow and 100,000 GPD industrial flow.
The effluent limits recommended for the SOC are the existing permit limits of 30
mg/1 of BOD5, 30 mg/1 of TSS and 200/100m1 of fecal coliform. Model inputs included 96
mg/1 of CBOD (30 mg/1 of BOD5 * 3.2, CBOD/BOD5 ratio determined from long-term
monitoring data) and 74.25 mg/1 of NBOD ( highest NH3 monthly average of 16.5 mg/1*
4.5) at the pre-SOC and post-SOC flows. The model results for both wasteflows
demonstrate no significant depression of the instream DO level or extension of the zone of
impact when the wasteflow is increased.
A mass balance analysis was conducted on the parameters that the proposed
industrial facility, Bristol Compressors, had indicated would be present in the wasteflow
contributed to the Sparta facility. The allowable concentrations for these substances:
cadmium, cyanide, mercury, chromium, copper, nickel, lead, zinc, silver and arsenic were
compared to the predicted discharge levels of industrial flow. It was determined that levels
of cadmium, cyanide and mercury exceeded the allowable concentrations and that it will be
necessary to limit these constituents eventually in the NPDES permit. Effluent monitoring
for chromium, copper, nickel, lead, zinc, silver and arsenic will be also necessary. For
protect against toxicity in the Little River, quarterly chronic toxicity monitoring at 5.5%
should be included in the SOC.

This memo is to confirm a meeting with the Town of Sparta on
Thursday, March 24, 1994 at 10:00 am at the Town Hall.
The main objective of this meeting is to arrive at a draft SOC.
This objective should be accomplished after discussing the
following items:
1) Inflow & Infiltration (I&I)
a) An instantaneous flow in the month of February 1994 shows
a 0.800 MGD. Also monthly DMR's record = 0.340 MGD daily
flows.
b) Brief update on the progress of new and old sewer line
connections and repairs. Need a schedule for completion of
your I&I work.
2) Bristol Compressor
a) Date the pretreatment facility will be completed.
b) Date the POTW will receive flow from the company. Supply a
schedule for a phase -in of the total flow.

Speculative Limits for Town of Sparta
NPDES Permit # NC0026913
Town of Sparta WWTP

The enclosed letter from the Town of Sparta is a request for written speculative limits for
an increase in flow to 0.5 and 0.75 MGD. Based on a discussion with the Town's
consultant, the only flow for which spec limits are need is 0.75 MGD since they have also
requested a permit modification for 0.6 MGD which includes a new industry's
contribution.
