A (11). CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time'ex'hibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 0.7%.
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 If 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 11 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 Iftarameter code TGP3B for the
pass/fail results and THP313 for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
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 desionate 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.
A (12). Ash Pond
Beginning on the effective date of this permit and lasting until expiration, there shall be no discharge of plant wastes
to the ash pond unless the permittee provides and maintains at all times a minimum free water volume equivalent to
the sum of the maximum 24-hour plant discharges plus all direct rainfall and all runoff flows to the pond resulting
from a 10-year, 24-hour rainfall event, when using a runoff coefficient of 1.0.
During the term of the permit, the permittee shall remove settled material from the ponds or otherwise enlarge the
available storage capacities in order to maintain the required minimum,vokumes at alldimes. Annually the permittee
shall determine and report to the permit issuing authority: (1) the actual free water volume of the ash pond, (2)
physical measurements of the dimensions of the free water volume in sufficient detail to allow validation of the
calculated volume, and (3) a certification that the required volume is available with adequate safety factor to include
all solids expected to be deposited in the ponds for the following year. Any changes to plant operations affecting
such certification shall be reported to the Director within five days.
NOTE: In the event that adequate volume has been certified to exist for the term of the permit, periodic certification
is not needed.
A (13). CHEMICAL METAL CLEANING WASTES
It has been demonstrated that under certain conditions it is possible to reduce the concentration of metals in boiler
cleaning wastes in the range of 92 to 99+ percent by treatment in ash ponds. Because of dilution problems, and the
existence of' boundary interface layers at the extremities of the plume, it is difficult to prove beyond doubt that the
quantity of iron and copper discharged will always be less than one milligram per liter times the flow of metal
cleaning when treated in this manner.
Permit No. NC0004774
SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS (Continued)
A (13). CONTINUED...
The application of physical/chemical methods of treating wastes has also been demonstrated to be effective in the
treatment of metal cleaning wastes. However, the effectiveness of ash pond treatment should be considered in
relation to the small differences in effluent quality realized between the two methods.
It has been demonstrated that the presence of ions of copper, iron, nickel, and zinc in the ash pond waters was not
measurably increased during the ash pond' equivalency demonstration at the Duke Power Company's Riverbend
Steam Station. Therefore, when the following conditions are implemented during metal cleaning procedures,
effective treatment for metals can be obtained at this facility:
(1) Large ash basin providing potential reaction volumes.
(2) Well-defined shallow ash delta near the ash basin influent.
(3) Ash pond pH of no less than 6.5 prior to metal cleaning waste addition.
(4) Four days retention time in ash pond with effluent virtually stopped.
(5) Boiler volume less than 86,000 gallons.
(6) Chemicals for cleaning to include only one or more of the following:
(a) Copper removal step- sodium bromate, NaBr03; ammonium carbonate, (NH4)2C03; and ammonium
hydroxide, NH40H.
(b) Iron removal step-hydrochloric acid, HCl; and ammonium bifluoride, (NH4)BF2 and proprietary
inhibitors.
(7) Maximum dilution of wastes before entering ash pond 6 to 1.
(8) After treatment of metal cleaning wastes, if monitoring of basin effluents as required by the permit reveals
discharges outside the limits of the permit. permittee will re-close the basin discharge, conduct such in-basin
sampling as necessary to determine the cause of nonconformance, will take appropriate corrective actions, and
will file a report with EPA including all pertinent data.
A (14). FLOATING MATERIALS
The Permittee shall report all visible discharges of floating materials, such as an oil sheen, to the Director when
submitting DMRs.
A (15). DIKE INSPECTIONS
The permittee shall check the diked areas for leaks by a visible inspection and shall report any leakage detected.
A (16). CHEMICAL DISCHARGES
Discharge of any product registered under the Federal Insecticide, Fungicide, and Rodenticide Act to any waste
stream which may ultimately be released to lakes, rivers, streams or other waters of the United States is prohibited
unless specifically authorized elsewhere in this permit. Discharge of chlorine from the use of chlorine gas, sodium
hypochlorite, or other similar chlorination compounds for disinfection in plant potable and service water systems and
in sewage treatment is authorized. Use of restricted use pesticides for lake management purposes by applicators
licensed by the N.C. Pesticide Board is allowed.
