Current through Register Vol. 24-06, March 15, 2024
In addition to the general applicability of chapters 173-400
and 173-490 WAC to all emission sources; no sulfite pulping mill shall cause or
permit air contaminant emissions in excess of the limits listed below. Specific
emission standards listed in this chapter will take precedence over the general
emission standards of chapter 173-400 WAC.
(1) Sulfur dioxide.
(a) The total average daily emissions from a
sulfite pulping mill, or a portion of a sulfite pulping mill which practices
incineration of the spent sulfite liquor, shall not exceed ten grams of sulfur
dioxide per kilogram (twenty pounds per ton) of air dried, unbleached pulp
produced.
(b) The total average
daily emissions from a sulfite pulping mill, or a portion of a sulfite pulping
mill that does not incinerate the spent sulfite liquor, shall not exceed two
grams of sulfur dioxide per kilogram (four pounds per ton) of air dried,
unbleached pulp produced.
(c) The
blow system emissions shall not exceed 0.1 grams of sulfur dioxide per minute,
on a fifteen minute average, per kilogram (0.2 pounds per ton) of air dried,
unbleached pulp discharged from the digester.
(d) Emissions from the recovery system and
acid plant shall not exceed 800 ppm of sulfur dioxide for any hourly
average.
(e) Emissions from
recovery systems constructed after January 24, 1972, shall not exceed 300 ppm
of sulfur dioxide for any hourly average.
(f) Emissions from any emissions unit, other
than a recovery system, a blow system or an acid plant, shall not exceed 1000
ppm of sulfur dioxide, corrected to seven percent oxygen in the case of
combustion unit, for any hourly average.
(2) Particulate.
(a) Emissions of particulate from recovery
systems constructed before January 24, 1972, shall not exceed 0.23 grams per
dry cubic meter of exhaust at standard conditions (0.10 grains/dscf) corrected
to eight percent oxygen.
(b)
Emissions of particulate matter from recovery systems constructed after January
24, 1972, shall not exceed 0.14 grams per dry cubic meter of exhaust at
standard conditions (0.06 grains/dscf) corrected to eight percent
oxygen.
(c) The emission of
particulates from emissions units other than acid plants or recovery systems
shall not exceed the following maximums:
(i)
0.46 grams per dry cubic meter at standard conditions (0.2 grains/dscf)
corrected to seven percent oxygen, for units which combust wood and wood
residue to produce steam and which commenced construction prior to January 1,
1983.
(ii) 0.12 grams per dry cubic
meter at standard conditions (0.05 grains/dscf) corrected to seven percent
oxygen, for units which combust fuel other than wood and wood residue to
produce steam, and which commenced construction after January 1,
1983.
(iii) 0.23 grams per dry
cubic meter at standard conditions (0.1 grains/dscf) corrected to seven percent
oxygen in the case of combustion units, for units not classified under (c) (i)
or (ii) of this subsection.
(3) Opacity.
(a) No person shall cause or allow the
emission of a plume from a recovery system or acid plant which has an average
opacity greater than thirty-five percent, for more than six consecutive minutes
in any sixty minute period.
(b)
Visible emissions from units other than acid plants or recovery systems shall
comply with WAC
173-400-040(2),
except when an alternative opacity limit established under WAC
173-400-081
or
173-400-082
is applicable.
(4)
Operation and maintenance. At all times, including periods of abnormal
operations and upset conditions, owners and operators shall, to the extent
practicable, maintain and operate any affected facility, including associated
air pollution control equipment, in a manner consistent with good air pollution
control practice. Determination of whether acceptable operating and maintenance
procedures are being used will be based on information available to ecology
which may include, but is not limited to, monitoring results, opacity
observations, review of operating and maintenance procedures, and inspection of
the source.
(5) No recovery system
shall emit total reduced sulfur (TRS) gases in excess of 17.5 ppm for a daily
average.
(6) More restrictive
limits. Ecology may set more restrictive emissions limits than the specific
limits set in this chapter (after public involvement and hearing), if there is
reason to believe that the emission(s) from a source is a cause of public
nuisance or a cause of violation of ambient air quality standards. The source
shall, within ninety days from notification of the more restrictive limits,
achieve operation that will prevent further recurrence of the nuisance or
violation.
(7) Source testing. To
demonstrate compliance with this chapter, the provisions of WAC
173-400-105
shall apply to all sources to which this chapter is applicable.
(8) Alternative emission limitation. An owner
or operator may request an alternative emission limitation (as defined in WAC
173-400-030 ) under:
(a) WAC
173-400-081
for an action covered under a notice of construction application; or
(b) WAC
173-400-082
for a permit modification.
