Part III Permit No. NC0056863
F. 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 90% (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 January, April, July, and October. 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.

Special Condition(s): Chronic Toxicity Test
Permits Sr Engineering Comments:
This is a renewal of a permit for the Town of Rose Hill's WWTP. The facility discharges into a zero -
flow stream, and the permit has chronic toxicity testing at 90% and ammonia limits of 2/4. Instream
monitoring data indicate some DO problems downstream of the facility; however, overall the data
look good. P&E recommends renewal with existing limits. Region: Please comment on whether or not
the permittee has installed a
stand-by power supply at the site.

may not be regenerated on the wastewater treatment plant she;
(2) Aerated Lagoons. A basin in which all solids are maintained in suspension and by which biological oxidation or organic matter Is reduced through artificially
accelerated transfer of oxygen on a flow -through basis;
(3) Aeration. A process of bringing about intimate contact between air or Ngh purity oxygen in a liquid by spraying. agttatlon or dffuston;(3a) Extended
Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours.
(4) Agriculturally managed she. Any she on which a crop is produced, rr.anaged. and harvested (Crop Includes grasses, grains, trees, etc.);
(5) Air Stripping. A process by which the ammonium ion is first converted to dissolved ammonia (pH adjus;ment) with the ammonia then released to the
atmosphere by physical means; or other similar processes which remove petroleum products such as beacons, toluene, and xytene;
(6) Carbon Regeneration. The regeneration of exhausted carbon by the use of a furnace to provide extremely high temperatures which volatilize and oxidize the
absorbed impurities;
(7) Carbonaceous Stage. A stage of wastewater treatment designed to achieve secondary' effluent limits;
(8) Centrifuge. A mechanical device In which centrifugal force is used to separate solids from liquids or to separate liquids of different densidas;
(9) Chemical Addhlon Systems- The addttlon of chemical(s) to wastewater at an application point for purposes d Improving solids removal, pH adjustment,
alkalinity control. etc.; the capability to experiment with different chemicals and different application points to active a specific result wilt be considered one
system; the capability to add chemical(s) to dual units wilt be rated as one system; capability to add a chemical at a different application points for different
purposes will resuh In the systems being rated as separate systems;
(10) Chemical Sludge Conditioning. The addition of a chemical compound such as Erne, ferric chloride. or a polymer to wet sludge to coalesce the mass prior to
its application to a dewatering device;
(11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing Inorganic, non -toxic materials from sand, gravel,
crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping facilities or any other appurtenances;
(12) Combined Removal of Carbonaceous BOO and Nitrogenous Removal by Nitrification- A single stage system required to achieve permit effluent firths on BOD
and ammonia nhrogen within the same biological reactor,
(13) Dechtorinatlon. The partial or complete reduction of residual chorine in a llqub by any chemical or physical process;
(14) Denhrlitcatlon Process. The conversion of nitrate -nitrogen to nitrogen gas;
