Subject: NPDES Permit Modification
NPDES No. NC0000752
Roanoke Rapids Mill
Halifax County
Dear Mr. Puryear:
In accordance with the application for a discharge permit modification received on
November 19, 1998, the Division is forwarding herewith the subject NPDES permit
modification. This permit is issued pursuant to the requirements of North Carolina General
Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated December 6, 1983.
In a letter dated November 18, 1998, Champion requested reduction or elimination of
monitoring for ammonia and mercury. After evaluating the effluent data from the Roanoke
Rapids Mill, the Division has made the following modifications to the permit:
1) The monitoring for ammonia has been reduced from 3/Week to Monthly. As discussed
with Mr. Myrl Nisely, Champion will review test procedures to identify a method that will
utilize a lower detection level that is constant month to month.
2) Monitoring for mercury has been eliminated. Based on information provided by Mr.
Nisely, the last time mercury was detected in the effluent was in 1995. The concentration of
mercury at that time was at 0.2 ug/1, which is at the detection level. Monthly mercury data
since that time has shown mercury concentrations below detection levels. Mr. Nisely
confirmed that mercury concentrations were incorrectly recorded on the DMRs without the
«�» sign.
If any parts, measurement frequencies or sampling requirements contained in this permit
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.

Please take note that this permit is not transferable. Part II, E.4. addresses the
requirements to be followed in case of change in ownership or control of this discharge.
This permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Water Quality or permits required by the Division of Land
Resources, Coastal Area Management Act or any other Federal or Local governmental permit
that may be required.
If you have any questions concerning this permit, please contact Steve D. Pellei at

4 Monitoring for pentachlorophenols and trichlorophenols is not required based on the information contained in the Champion Letter dated
December 15, 1988. If chlorophenolic-containing biocides are used at the facility, monitoring for pentachlorophenols and trichlorophenols
shall commence immediately on a weekly basis at the effluent by grab samples for the duration of the use of the biocides and for a period of
not less than two months after discontinuing use of the biocides.
Daily shall mean everyday except Saturdays, Sundays, and legal holidays.
There shall be no discharge of floating solids or visible foam in other than trace amounts.
Special permit conditions applicable to the subject facility are listed on the Supplement to Effluent Limitations and Monitoring Requirements

Re: Request for Reduction in Ammonia and Mercury Testing
Dear Mr. Goodrich:
rvo'rE No SEC 3F,.fT
Ada' /2-1"rgi
NPDES permit No. NC0000752 states that Champion may request a decrease in
monitoring frequency for effluent ammonia after collecting at least one year's data.
In addition to that request, I wish to discuss data and monitoring requirements for
mercury.
Ammonia
Ammonia measurements since the October, 1997 permit renewal are on the following
table. The average of points above Non -Detect is 1.07 ppm. We rely on naturally
occurring nitrogen for the microorganisms, that is, we do not add extra nitrogen in
any form. In our opinion, the levels being released pose no threat to dissolved oxygen
levels in the Roanoke River. We ask for monitoring to be discontinued.

The permit renewal also required us to monitor mercury in the effluent monthly. The
possibility that we had mercury was based upon a statistical analysis (attached) in
which one reading of 0.3 micrograms/1 was present in the data. Otherwise, all values
were either 0.2 or < 0.2, the detection limit.

Data collected since that time are as follows:

All are below the detection limit. We do not use mercury in any process and are
convinced that we do not have mercury. We believe the reading of 0.3 on 12/14/94 is
an outlier datapoint. We ask to discontinue the monthly monitoring of mercury.
