SUBJECT: Dioxin Control Program - Judicial Cdisent drder
in'
Dear Preston: I
This is the second annual report on the status of the dioxiq
control program at Federal's Riegelwood mill.
_ 0
The stipulated terms contained in items 14.A and 14.B of th;J
consent order specifically address a schedule to reduce/eliminate
dioxin formation. The following is a review of the current stag
of each item in the schedule:
A. REDUCE/ELIMINATE DIOXIN FORMATION
1. Complete No. 5 cooling tower and chilled water system to
provide high C102 substitution capability in No. 1 bleach
plant.
December 1993
Status
This project was completed on September 16, 1993.
2. Install oxidative extraction to provide high C102
substitution capability in No. 3 bleach plant.
December 1994
Status
Federal has completed modifications to the No. 3 bleach plant
to improve mixing in the chlorine dioxide stages subsequent
to the chlorination stage. This has provided for high
substitution levels in the chlorination stage without
installing oxidative extraction. These modifications
resulted in 32,000 tons of elemental chlorine -free pulp
produced in the No. 3 bleach plant during 1993, and 85,623
tons in 1994. Therefore, Federal has complied with this
section of the plan. I509002

3. Modernize No. 2 bleach plant to provide high C102
substitution capability or build new No. 4 bleach plant with
the capability of providing high C102 substitution.
December 1996
status
Federal has completed a study to modernize the No. 2 bleach
plant versus building a new No. 4 bleach plant. It has been
decided to abandon modernizing the No. 2 bleach plant and to
pursue the new No. 4 bleach plant project. Preliminary
design work has been initiated.
B. WASTEWATER TREATMENT SOLIDS CONTROL
1. Dredge South Bay
Status
This project was completed in August 1993.

On December 18, 1978, NPDES Permit No. NC0003298 was issued to Federal Paper
Board Company, Inc. (FPB). The permit contained an expiration date of December 31, 1979, '
(due to the fact that no final BPT guidelines for the industry had been promulgated), and was
different from the previous EPA permit (which was issued on August 26, 1973, and expired
on June 30, 1978) in that the State issued permit did not contain both winter an summer
effluent limits for BOD5. Subsequently, on January 24, 1979, FPB requested and
adjudicatory hearing to contest the fact that no winter limits for BODS were contained in the
permit. The adjudicatory hearing request was never resolved; the permit was never extended
beyond the December 31, 1979, expiration date; and FPB thus continued to operate under the
dual (i.e. summer/winter) limits as contained in the EPA permit. FPB submitted an
application for reissuance of the adjudicated permit on July 30, 1979. On December 8, 1982,
due to an expansion in the mill's production capacity, FPB submitted a new application for
reissuance of the permit.
On April 25, 1984, Robert Helms, Director of the Division, assessed FPB a civil
penalty of $729,000.00 for 243 effluent violations during the period of January 1, 1981 thru
March 31, 1984. The assessment was reduced to $100,000.00 with FPS agreeing to resolve
the matter.
Since October 11, 1984 interim effluent limitations for BOD5 and TSS have been set
forth in a SOC (EMC WQ 84-30). On August 15, 1988, FPB requested modifications of the
BOD5 winter/summer limits contained in the August 1, 1988 permit. In a letter dated
October 3, 1988 Paul Wilms, then Director of the Division, denied FPB's request for the
modifications. FPB petitioned the State for a hearing on the denial. On February 3, 1989, the
Office of Administrative Hearings (88 NRC 1361) stayed the permit conditions for-BOD5
until April 1, 1989, and on April 25, 1989, the permit was again stayed, this time until
September 29, 1989. A SOC (EMC WQ 84-30 AdII) was negotiated as a settlement.
Listed below is a brief history and'description of the SOC's issued to the Company.

On or before the expiration of SOC 84-30 Ad on December 31, 1988, FPB was to
submit a report which evaluated the effectiveness of the supplemental oxygen system. The
NPDES permit issued also expired on December 31, 1988. The permit was reissued in July,
1988 with the anticipation that the study would allow a more precise determination of the
assimilative capacity of the river. This data was to be used in determining the effluent BOD
limits to be contained in the permit when it reissued in January of 1989. Delays in the
completion of the study due to weather conditions postponed the reissuance of the permit.
The latest NPDES Permit was issued on October 10, 1990. FPB filed a petition for a hearing
on the terms of that permit.

RJ
On January 17, 1991 a hearing on the petition of the NPDES permit was held. A
partial settlement agreement resolved all contested permit issues except for effluent limits for
dioxin. The effluent limits and compliance date for dioxin were stayed. Under the partial
settlement agreement, the parties agreed that the SOC (EMC WQ NO.84-30 Ad 11)
superceeded certain terms and conditions of the NPDES permit.
On April 14,1992, George Everett, Director sent FPB a letter saying he would
support a variance from the summer limitations to include the months of April and May,
subject to the approval of the EMC. In addition, he also accepted the proposal to pursue a
combination of increased treatment and holding capacity to meet BOD5 limitations of 5,000
lbs/day during the summer and 10,0001bs/day during the winter. The letter also was the
DEHNIt response required by conditions 2 (c) (8) (iii) of the SOC. Therefore, per condition
2 (c) (9) of the SOC, FPB was required to submit plans & specifications and a request for an
A to C by 1/14/93.
On 6/17/92 a draft NPDES permit was sent to FPB.
On 6/29/92 a revised draft NPDES was sent to FPB. (Maximum BOD5 limits were
increased).
A public hearing on the permit and variance was held in Whiteville on 10/06/92.
On 12/09/92 the EMC approved an NPDES permit for FWB with a variance which
would allow the winter discharge period to include the months of April and May (Existing
rules define the summer months as April thru October). The permit contained limits on
BOD5 of 5,000 lbs/day during the summer and 10,000 lbs/day during the winter.
FPB filed a Petition for Contested Case Hearing on 12/22/92.
FPB submitted plans and specifications with request for a A to C on 1/13/93.
Submittal contained location for holding pond on company golf course. (Company has
recently met with W1RO staff concerning final plans and moving holding pond location).
On 4/01/93 DEM completed preliminary engineering review of plans &
specifications.
Final Settlement Agreement on permit on 5/17/93.
On June 23, 1993 NPDES permit was issued with a new effective date of the dioxin
limit set rack to 12/31/96, or until date of completion of dioxin control program, whichever
is earlier. '
FPB submitted plans & specifications for additional treatment capacity in existing
holding pond (dioxin control program) on 11/04/93.
COMPLIANCE
FPB is currently in compliance with their SOC. The only violation of the SOC was
during December 27, 1989 thru January 7, 1990 when FPB exceeded the daily maximum
BOD5 interim limit contained in SOC (EMC WQ 84-30 Ad) due to an abnormally snowfall
and cold weather conditions. A NOV was mailed on 2/02/90. In July, 1990 EPA sent a 309
letter concerning the violations and George Everett responded to EPA in July, 1990.
