Dear Mr. Boyer:
This letter is to confirm your telephone conversation with Charles Weaver of my staff on November 20,
1996. After a review of your request for annual toxicity testing, it was determined that an error was made in
Part III, Section F. of your permit. The requirement to perform five toxicity tests has already been met by your
facility.
Please find enclosed amended pages for Part III, which should be inserted into your permit. The old
pages should be discarded. All other terms and conditions contained in the original permit remain unchanged
and in full effect. This permit modification is issued pursuant to the requirements of North Carolina General
Statutes 143-215.1 and the Memorandum of Agreement between North Carolina and the U. S. Environmental
Protection Agency.
If any parts, measurement frequencies or sampling requirements contained in this permit modification
are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty. (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative Hearings,
Post Office Drawer 27447, Raleigh, North Carolina 27611-7447. Unless such demand is made, this decision
shall be final and binding.
If you have any questions, please call Charles Weaver at [phone], extension 511.
Sincerely,
7/4/i/2:(44.

E. ACUTE TOXICITY PERMIT LIMIT (QUARTERLY) gam- ?i/ It 165
The-permitteesy tests on a quarterly basis using protocols defined as definitive
iDocument 600/4-85 ' `3 entitled "The Acute Toxicity of Effluents to Freshwater and Marine
Organisms." The monitoring shall be performed as a Daphnia pulex or Ceriodaphnia 48 hour static test,
using effluent collected as a 24-hour composite. The LC50 of this effluent using the previously stated
methodology may at no time in any toxicity test be less than 90%. Effluent samples for self -monitoring
purposes must be obtained during representative effluent discharge below all waste treatment. 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.
The parameter code for this test is TAA3D if using Daphnia pulex, or TAA3B if using Ceriodaphnia. All
toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Form (MR-1) for the month in which it was performed, using the appropriate parameter code.
Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of Water Quality
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 test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water Quality indicate potential impact on water quality standards in 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.
F. ACUTE TOXICITY PASS/FAIL MONITORING (ANNUAL)
,47. 7Zzi
The permittee shall conduct annual toxicity tests using protocols defined in the North Carolina Procedure
Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent
Concentration" (Revised -July, 1992 or subsequent versions). The monitoring shall be performed as a
Fathead Minnow (Pimephales promelas) 24 hour static test. The effluent concentration defined as
treatment two in the procedure document will be 90%. Effluent samples for self -monitoring purposes
must be obtained below all waste treatment. The permittee will conduct one test annually, with the
annual period beginning in January of the calendar year of the effective date of the permit. The annual
test requirement must be performed and reported by June 30. If no discharge occurs by June 30,
notification will be made to the Division by this date. Toxicity testing will be performed on the ext /4.
discharge event for the annual test requirement.

of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream.

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 follow-up testing to be completed no later than the last day of the month following the
month of the initial monitoring.
G. Biocide Condition
The permittee shall not use any biocides exept those approved in conjunction with the permit application.
The Permittee shall notify the Director ir. writing not later than ninety (90) days prior to instituting use of
any additional biocide used in the cooling system which may be toxic to aquatic life other than those
previously reported to the Division of Water Quality. Such notification shall include completion of
Biocide Worksheet Form 101 and a map locating the discharge point and receiving stream.
H. After monitoring for a minimum of three years, upon written request, OCPSF monitoring data
will be reviewed by the Division to determine if a reduction in monitoring frequency is warranted. Data
submitted for review should be in a tabular format for the sampling period under consideration.
I. When an approved analytical protocol with the appropriate minimum detection level is followed
and a result of "non -detectable" or "below quantitation limit" is obtained, the permittee will be considered
to be in compliance with the numerical permit limit for that pollutant.
J. Alternative Test Methods for OCPSF Parameters
The use of EPA test method 524.2 is allowed as a substitute for test methods in 40 CFR Part 136 to monitor
OCPSF parameters.
