Subject: NPDES Permit Modification
Permit No. NC0063029
Camp Lejeune WWTP
Onslow County
Dear Mr, Warren:
The Division issued the subject permit on March 16, 1998. A review of the file by the Division's
Aquatic Toxicology Unit identified two errors in the permit. This modification is being issued to correct
those errors. The modification changes the months listed for toxicity testing on the Effluent Limitations and
Monitoring Requirements pages to make them consistent with the months listed in Special Conditions A.(8)
and A.(11). The modification also corrects Special Condition A. (11), which inadvertently was printed
without a final paragraph.
Please find enclosed the revised Effluent Limitations and Monitoring Requirements pages and the
revised pages for Special Condition A.(11). These pages should be inserted into your permit. The old pages
may then 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 a written petition conforming to Chapter
150B of the North Carolina General Statutes, 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 additional questions, please contact Charles Weaver of the NPDES Unit at (919)
733-5083, extension 511.

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS (Continued)
• The growth endpoint will be determined using Appendix G of Short —Term Methods for Estimating the Chronic Toxicity
of Effluents and Receiving Waters to Marine and Estuarine Organisms, Second Edition, EPA/600-4-91/003, July 1994
using an alpha level of 0.01.
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 TGP3E. Additionally, DWQ Form AT-4 (original)
is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
4401 Reedy Creek Road
Raleigh, North Carolina 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 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 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 the permittee fail to monitor during a month in which toxicity monitoring is required, 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 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) SENSITIVITY TESTING (pertains to operation at the expanded flow only)
The facility may perform sensitivity testing to compare sensitivity of the effluent to Mysidopsii bahia and Ceriodaphnia dubia.
There should be three monthly comparisons by splitting effluent samples and conducting pass/fail tests as described in Special
Conditions A. (8) and A. (11) at 5%. The Ceriodaphnia chronic procedure should be modified to incorporate the use of three
samples and daily test solution renewals.
The results of these tests, including all chain -of -custody sheets, bench sheets, and statistical analyses should be submitted to the
following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Water Quality
4401 Reedy Creek Road
Raleigh, North Carolina 27607
The results will be evaluated based on the best professional judgment of Aquatic Toxicology Group personnel. Should the
Mysidopsis tests indicate that those organisms are routinely more sensitive to the effluent, the facility will be required to use
those organisms for monitoring as described in Special Condition A (9). Should the testing indicate that Ceriodaphnia are as or
more sensitive to the effluent, the facility may choose which organism it will use for the remainder of the permit cycle.
