Current through Register Vol. 63, No. 3, March 1, 2024
(1) Emission of
Total Reduced Sulfur (TRS):
(a) Recovery
Furnaces:
(A) The emissions of TRS from each
recovery furnace placed in operation before January 1, 1969, may not exceed 10
ppm and 0.15 Kg/metric ton (0.30 pound/ton) of production as daily arithmetic
averages;
(B) TRS emissions from
each recovery furnace placed in operation after January 1, 1969, and before
September 25, 1976, or any recovery furnace modified significantly after
January 1, 1969, and before September 25, 1976, to expand production must be
controlled such that the emissions of TRS may not exceed 5 ppm and 0.075
Kg/metric ton (0.150 pound/ton) of production as daily arithmetic
averages.
(b) Lime Kilns.
Lime kilns must be operated and controlled such that emissions of TRS may not
exceed 20 ppm as a daily arithmetic average and 0.05 Kg/metric ton (0.10
pound/ton) of production as a daily arithmetic average. This subsection applies
to those sources where construction was initiated prior to September 25,
1976.
(c) Smelt Dissolving Tanks.
TRS emissions from each smelt dissolving tank may not exceed 0.0165 gram/Kg BLS
(0.033 pound/ton BLS) as a daily arithmetic average.
(d) Non-Condensables. Non-condensables from
digesters, multiple-effect evaporators and contaminated condensate stripping
must be continuously treated to destroy TRS gases by thermal incineration in a
lime kiln or incineration device capable of subjecting the non-condensables to
a temperature of not less than 650° C. (1,200° F.) for not less than
0.3 second. An alternate device meeting the above requirements must be
available in the event adequate incineration in the primary device cannot be
accomplished. Venting of TRS gases during changeover must be minimized but in
no case may the time exceed one-hour.
(e) Other Sources:
(A) The total emission of TRS from other
sources may not exceed 0.078 Kg/metric ton (0.156 pound/ton) of production as a
daily arithmetic average;
(B)
Miscellaneous Sources and Practices. If DEQ determines that sewers, drains, and
anaerobic lagoons significantly contribute to an odor problem, a program for
control will be required.
(2) Particulate Matter:
(a) Recovery Furnaces. The emissions of
particulate matter from each recovery furnace stack may not exceed:
(A) 2.0 kilograms per metric ton (4.0 pounds
per ton) of production as a daily arithmetic average;
(B) 0.30 gram per dry standard cubic meter
(0.13 grain per dry standard cubic foot) as a daily arithmetic average;
and
(C) Thirty-five percent opacity
for a period or periods aggregating more than 30 minutes in any 180 consecutive
minutes or more than 60 minutes in any 24 consecutive hours (excluding periods
when the facility is not operating).
(b) Lime Kilns. The emissions of particulate
matter from each lime kiln stack may not exceed:
(A) 0.50 kilogram per metric ton (1.00 pound
per ton) of production as a daily arithmetic average;
(B) 0.46 gram per dry standard cubic meter
(0.20 grain per dry standard cubic foot) as a daily arithmetic average;
and
(C) The visible emission
limitations in section (4).
(c) Smelt Dissolving Tanks. The emission of
particulate matter from each smelt dissolving tank vent may not exceed:
(A) A daily arithmetic average of 0.25
kilogram per metric ton (0.50 pound per ton) of production; and
(B) The visible emission limitations in
section (4).
(d)
Replacement of or modification or a rebuild of an existing particulate
pollution control device for which a capital expenditure of 50 percent or more
of the replacement cost of the existing device is required, other than ongoing
routine maintenance, after July 1, 1988 will result in more restrictive
standards as follows:
(A) Recovery Furnaces:
(i) The emission of particulate matter from
each affected recovery furnace stack may not exceed 1.00 kilogram per metric
ton (2.00 pounds per ton) of production as a daily arithmetic average;
and
(ii) 0.10 gram per dry standard
cubic meter (0.044 grain per dry standard cubic foot) as a daily arithmetic
average.
(B) Lime Kilns:
(i) The emission of particulate matter from
each affected lime kiln stack may not exceed 0.25 kilogram per metric ton (0.50
pound per ton) of production as a daily arithmetic average; and
(ii) 0.15 gram per dry standard cubic meter
(0.067 grain per dry standard cubic foot) as a daily arithmetic average when
burning gaseous fossil fuel; or
(iii) 0.50 kilogram per metric ton (1.00
pound per ton) of production as a daily arithmetic average; and
(iv) 0.30 gram per dry standard cubic meter
0.13 grain per dry standard cubic foot) as a daily arithmetic average when
burning liquid fossil fuel.
(C) Smelt Dissolving Tanks. The emissions of
particulate matter from each smelt dissolving tank vent may not exceed 0.15
kilogram per metric ton (0.30 pound per ton) of production as a daily
arithmetic average.
(3) Sulfur Dioxide (SO2). Emissions of sulfur
dioxide from each recovery furnace stack may not exceed a three-hour arithmetic
average of 300 ppm on a dry-gas basis except when burning fuel oil. The sulfur
content of fuel oil used must not exceed the sulfur content of residual and
distillate oil established in OAR 340-228-0100 and 340-228-0110,
respectively.
(4) Emissions from
each kraft mill source, with the exception of the mill's emissions attributable
to a recovery furnace, may not equal or exceed 20 percent opacity as a six
minute average.
(5) New Source
Performance Standards. New or modified sources that commenced construction
after September 24, 1976, are subject to each provision of this rule and the
New Source Performance Standards, 40 CFR part 60 subpart BB as adopted under
OAR 340-238-0060, whichever is more stringent.
NOTE: Except for OAR 340-234-0210(1), this rule is included in
the State of Oregon Clean Air Act Implementation Plan that EQC adopted under
OAR 340-200-0040.
