Subject: NPDES Permit Modification
Permit No. NC0029980
Miller Brewing Co.
Rockingham County
On February 10, 1997 the Division of Water Quality issued NPDES Permit No. NC0029980 to Miller Brewing
Company for their Eden, NC facility. A review of the permit file has indicated that an error was inadvertently made
in the permit. Accordingly, we are forwarding herewith modifications to the subject permit to correct the error. This
permit modification is to the supplement to effluent limitations page. The modification corrects the toxicity testing
condition to reflect the most current toxicity language.
Also, the BAT langauge currently present in the permit is being removed based on concerns expressed to the
Division by Miller Brewing. Please note, however, that regardless of the removal of this language from the current
permit, this strategy will be employed at the time of next renewal. This modification removes the footnote for BOD
and TSS from the effluent limitations pages and removes the BAT special condition from the supplement to effluent
limitations page.
Please find enclosed an amended effluent page for outfall 001 and an ammended supplement to effluent
limitations page 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. These permit modifications are 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.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
The effluent dicharge shall at no time exhibit chronic toxicity using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised November 1995, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 2.1 %. The permit holder
shall perform quarterly monitoring using this procedure to establish compliance with the permit condition.
The tests will be performed during the months of February, May August and November. 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, 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 Rd.
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 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, then monthly
monitoring will begin immediately until such time that a valid test is submitted. Upon submission of a valid
test, 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.
