Definitions
The definitions in OAR 340-200-0020,
340-204-0010 and this rule apply to this division. If the same term is defined in
this rule and 340-200-0020 or 340-204-0010, the definition in this rule applies
to this division.
(1) "Baseline emissions rate"
means a source's actual emissions rate during the baseline period, as defined in
OAR 340-200-0020, expressed as pounds of emissions per thousand square feet of finished
product, on a 1/8" basis.
(2) "BLS" means black liquor
solids, dry weight.
(3) "Continuous monitoring"
means instrumental sampling of a gas stream on a continuous basis, excluding periods
of calibration.
(4) "Daily arithmetic average"
means the average concentration over the twenty-four hour period in a calendar day,
as determined by continuous monitoring equipment or reference method testing. Determinations
based on EPA reference methods using the DEQ Source Sampling Manual consist of three
separate consecutive runs having a minimum sampling time of sixty minutes each and
a maximum sampling time of eight hours each. The three values for concentration
(ppm or grains/dscf) are averaged and expressed as the daily arithmetic average
which is used to determine compliance with process weight limitations, grain loading
or volumetric concentration limitations and to determine daily emission rate.
(5) "Dry standard cubic meter"
means the amount of gas that would occupy a volume of one cubic meter, if the gas
were free of uncombined water, at a temperature of 20° C. (68° F.) and
a pressure of 760 mm of mercury (29.92 inches of mercury). The corresponding English
unit is dry standard cubic foot.
(6) "Kraft mill" or "mill"
means any industrial operation which uses for a cooking liquor an alkaline sulfide
solution containing sodium hydroxide and sodium sulfide in its pulping process.
(7) "Lime kiln" means any
production device in which calcium carbonate is thermally converted to calcium oxide.
(8) "Non-condensables" mean
gases and vapors, contaminated with TRS compounds, from the digestion and multiple-effect
evaporation processes of a mill.
(9) "Operations" includes
plant, mill, or facility.
(10) "Other sources" as used
in OAR 340-234-0200 through 340-234-0270 means sources of TRS emissions in a kraft
mill other than recovery furnaces, lime kilns, smelt dissolving tanks, sewers, drains,
categorically insignificant activities and wastewater treatment facilities including
but not limited to:
(a) Vents from knotters,
brown stock washing systems, evaporators, blow tanks, blow heat accumulators, black
liquor storage tanks, black liquor oxidation system, pre-steaming vessels, tall
oil recovery operations; and
(b) Any vent which is shown
to contribute to an identified nuisance condition.
(11) "Production" as used
in OAR 340-234-0200 through 340-234-0270 means the daily amount of air-dried unbleached
pulp, or equivalent, produced during the 24-hour period each calendar day, or DEQ
approved equivalent period, and expressed in air-dried metric tons (admt) per day.
The corresponding English unit is air-dried tons (adt) per day;
(12) "Recovery furnace" means
the combustion device in which dissolved wood solids are incinerated and pulping
chemicals recovered from the molten smelt. For OAR 340-234-0200 through 340-234-0270,
this term includes a direct contact evaporator, if present.
(13) "Recovery system" means
the process by which all or part of the cooking chemicals may be recovered, and
cooking liquor regenerated from spent cooking liquor, including evaporation, combustion,
dissolving, fortification, and storage facilities associated with the recovery cycle.
(14) "Smelt dissolving tank

by the recovery furnace.
(15) "Special problem area"
means the formally designated Portland, Eugene-Springfield, and Medford AQMAs and
other specifically defined areas that the EQC may formally designate in the future.
The purpose of such designation will be to assign more stringent emission limits
as may be necessary to attain and maintain ambient air standards or to protect the
public health or welfare.
(16) "Tempering oven" means
any facility used to bake hardboard following an oil treatment process.
(17) "Wigwam waste burner"
means a burner which consists of a single combustion chamber, has the general features
of a truncated cone, and is used for incineration of wastes.

Kraft Pulp Mills
340-234-0200
Statement of Policy and Applicability
(1) Policy. Recent technological developments
have enhanced the degree of malodorous emission control possible for the kraft pulping
process. While recognizing that complete malodorous and particulate emission control
is not presently possible, consistent with the meteorological and geographical conditions
in Oregon, it is hereby declared to be the policy of DEQ to:
(a) Require, in accordance
with a specific program and time table for all sources at each operating mill, the
highest and best practicable treatment and control of atmospheric emissions from
kraft mills through the utilization of technically feasible equipment, devices,
and procedures. Consideration will be given to the economic life of equipment, which
when installed, complied with the highest and best practicable treatment requirement.
(b) Require degrees and methods
of treatment for major and minor emission points that will minimize emissions of
odorous gases and eliminate ambient odor nuisances.
(c) Require effective monitoring
and reporting of emissions and reporting of other data pertinent to air quality
or emissions. DEQ will use these data in conjunction with ambient air data and observation
of conditions in the surrounding area to develop and revise emission and ambient
air standards, and to determine compliance therewith.
(d) Encourage and assist
the kraft pulping industry to conduct a research and technological development program
designed to progressively reduce kraft mill emissions, in accordance with a definite
program, including specified objectives and time schedules.
(2) Applicability. OAR 340-234-0200
through 340-234-0270 apply to existing and new kraft pulp mills.
NOTE: This rule is included in the
State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040

located or is proposed to be located in a special problem area or an area where
ambient air standards are exceeded or are projected to be exceeded or where the
emissions will have a significant impact in an area where the standards are exceeded;
or
(2) An odor or nuisance problem
has been documented at any mill, in which case the TRS emission limits may be reduced
below the regulatory limits; or DEQ may require the mill to undertake an odor emission
reduction study program; or

Monitoring
(1) Total Reduced Sulfur (TRS). Each
mill must continuously monitor TRS using the following:
(a) The monitoring equipment
must determine compliance with the emission limits and reporting requirements established
by OAR 340-234-0200 through 340-234-0270, and must continuously sample and record
concentrations of TRS;
(b) The sources monitored
must include, but are not limited to individual recovery furnaces, and lime kilns.
All sources must be monitored down-stream of their respective control devices, in
either the ductwork or the stack, using the DEQ Continuous Monitoring Manual;
(c) Unless otherwise authorized
or required by permit, at least once per year, vents from other sources as required
in OAR 340-234-0210(1)(e), other sources, must be sampled to demonstrate the representativeness
of the emission of TRS using EPA Method 16, 16A, 16B or continuous emission monitors.
Sampling using these EPA methods must consist of three separate consecutive runs
of one-hour each using the DEQ Source Sampling Manual. Continuous emissions monitors
must be operated for three consecutive hours using the DEQ Continuous Monitoring
Manual. All results must be reported to DEQ;
(d) Smelt dissolving tank
vents must be sampled for TRS quarterly except that testing may be semi-annual when
the preceding six source tests were less than 0.0124 gram/Kg BLS (0.025 pound/ton
BLS) using EPA Method 16, 16A, 16B or continuous emission monitors. Sampling using
these EPA methods must consist of three separate consecutive runs of one-hour each
using the DEQ Source Sampling Manual.
(2) Particulate Matter:
(a) Each mill must sample
the recovery furnace, lime kiln and smelt dissolving tank vent for particulate emissions
as measured by EPA Method 5 or 17 using the DEQ Source Sampling Manual. Particulate
matter emission determinations by EPA Method 5 must use water as the cleanup solvent
instead of acetone, and consist of the average of three separate consecutive runs
having a minimum sampling time of 60 minutes each, a maximum sampling time of eight
hours each, and a minimum sampling volume of 31.8 dscf each.
(A) When applied to recovery
furnace gases "dry standard cubic meter" requires adjustment of the gas volume to
that which would result in a concentration of 8% oxygen if the oxygen concentration
exceeds 8%.
(B) When applied to lime
kiln gases "dry standard cubic meter" requires adjustment of the gas volume to that
which would result in a concentration of 10% oxygen if the oxygen concentration
exceeds 10%.
(C) The mill must demonstrate
that oxygen concentrations are below the values in (A) and (B) above or furnish
oxygen levels and corrected data.
(b) Each mill must provide
continuous monitoring of opacity of emissions discharged to the atmosphere from
each recovery furnace stack using the DEQ Continuous Monitoring Manual.
(c) Recovery furnace particulate
source tests must be performed quarterly except that testing may be semi-annual
when the preceding six source tests were less than 0.225 gram/dscm (0.097 grain/dscf)
for furnaces subject to OAR 340-234-0210(2)(a) or 0.075 gram/dscm (0.033 grain/dscf)
for furnaces subject to OAR 340-234-0210(2)(d)(A);
(d) Lime kiln source tests
must be performed semi-annually;
(e) Smelt dissolving tank
vent source tests must be performed quarterly except that testing may be semi-annual
when the preceding six source tests were less than 0.187 kilogram per metric ton
(0.375 pound per ton) of production.
(3) Sulfur Dioxide (SO2).
Representative sulfur dioxide emissions from each recovery furnace must be determined
at least once each month by the average of three one-hour source tests using the
DEQ Source Sampling Manual or from continuous emission monitors. If continuous emission
monitors are used, the monitors must be operated for three consecutive hours using
the DEQ Continuous Monitoring Manual.
(4) Combined Monitoring.
DEQ may allow the monitoring for opacity of a combination of more than one emission
stream if each individual emission stream has been demonstrated with the exception
of opacity to be in compliance with all the emission limits of OAR 340-234-0210.
DEQ may establish more stringent emission limits for the combined emission stream.
(5) New Source Performance
Standards Monitoring. New or modified sources that are subject to the New Source
Performance Standards, 40 CFR part 60 subpart BB, must conduct monitoring or source
testing as required by subpart BB. In addition, when these rules are more stringent
than 40 CFR part 60 subpart BB, DEQ may require some or all of the relevant monitoring
in this section.
NOTE: This rule is included in the
State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040
with the exception of references to Total Reduced Sulfur.

Chronic Upset Conditions
If DEQ determines that an upset condition
is chronic and correctable by installing new or modified process or control procedures
or equipment, the owner or operator must submit to DEQ a program and schedule to
effectively eliminate the deficiencies causing the upset conditions. Such reoccurring
upset conditions causing emissions in excess of applicable limits may be subject
to civil penalty or other appropriate action.

Veneer and Plywood Manufacturing
Operations
(1) Veneer Dryers:
(a) Consistent with OAR 340-234-0500(1)
through (3), it is the object of this section to control air contaminant emissions,
including, but not limited to, condensable hydrocarbons such that visible emissions
from each veneer dryer are limited to a level which does not cause a characteristic
"blue haze" to be observable;
(b) No person may operate
any veneer dryer such that visible air contaminants emitted from any dryer stack
or emission point exceed:
(A) A daily average operating
opacity of 10 percent on more than two days within any 12-month period, with the
days separated from each other by at least 30 days, as measured by EPA Method 9;
and
(B) A maximum opacity of
20 percent at any time as measured by EPA Method 9.
(c) Particulate emissions
from wood fired veneer dryers may not exceed:
(A) 0.75 pounds per 1,000
square feet of veneer dried (3/8 inch basis) for units using fuel which has a moisture
content equal to or less than 20 percent by weight on a wet basis as measured by
ASTM D4442-84;
(B) 1.50 pounds per 1,000
square feet of veneer dried (3/8 inch basis) for units using fuel which has a moisture
content greater than 20 percent by weight on a wet basis as measured by ASTM D4442-84;
or
(C) 0.40 pounds per 1,000
pounds of steam generated in boilers which exhaust gases to the veneer dryer.
(d) Exhaust gases from fuel
burning equipment vented to the veneer dryer are exempt from OAR 340-228-0210;
(e) Each veneer dryer must
be maintained and operated at all times such that air contaminant generating processes
and all contaminant control devices must be at full efficiency and effectiveness
so that the emission of air contaminants are kept at the lowest practicable levels;
(f) No person may willfully
cause or permit the installation or use of any means, such as dilution, which, without
resulting in a reduction in the total amount of air contaminants emitted, conceals
an emission which would otherwise violate this rule;
(g) Where effective measures
are not taken to minimize fugitive emissions, DEQ may require that the equipment
or structures in which processing, handling, and storage are done, be tightly closed,
modified, or operated in such a way that air contaminants are minimized, controlled,
or removed before discharge to the open air;
(h) DEQ may require more
restrictive emission limits than provided in subsections (1)(b) and(c) for an individual
plant upon a finding by the EQC that the individual plant is located or is proposed
to be located in a special problem area. The more restrictive emission limits for
special problem areas may be established on the basis of allowable emissions expressed
in opacity, pounds per hour, or total maximum daily emissions to the atmosphere,
or a combination thereof.
(2) Other Emission Sources:
(a) The combined particulate
emissions from veneer and plywood mill sources, including, but not limited to, sanding
machines, saws, presses, barkers, hogs, chippers, and other material size reduction
equipment, process or space ventilation systems, and truck loading and unloading
facilities must not exceed a plant specific average hourly emission rate, pounds/hour,
determined by multiplying the plant production capacity by one pound per 1,000 square
feet. The plant production capacity is the maximum production in terms of 1,000
square feet on a 3/8 inch basis of finished product for a typical operating shift
divided by the number of hours in the operating shift.
(b) Excepted from subsection
(2)(a) are veneer dryers, fuel burning equipment, and refuse burning equipment.
(c) Compliance with the average
hourly emission rate is determined by summing the emissions from the affected sources
as determined by emission factor calculations or actual emissions data for a 24
hour period divided by 24.
(3) Monitoring and Reporting:
DEQ may require any veneer dryer facility to establish an effective program for
monitoring the visible air contaminant emissions from each veneer dryer emission
point. The program must be reviewed and approved by DEQ and must consist of the
following:
(a) A specified minimum frequency
for performing visual opacity determinations on each veneer dryer emission point;
(b) All data obtained must
be recorded on copies of a "Veneer Dryer Visual Emissions Monitoring Form" provided
by DEQ or on an alternative form which is approved by DEQ; and
(c) A specified period during
which all records must be maintained at the mill site for inspection by authorized
representatives of DEQ.

of raw materials outside the regularly used areas of the plant site is prohibited
unless the person who desires to temporarily store such raw materials first notifies
DEQ and receives written approval for said storage:
(A) When authorized by DEQ,
temporary storage areas must be operated to prevent windblown particulate emissions
from being deposited upon property not under the ownership of the person storing
the raw materials;
(B) Any temporary storage
areas authorized by DEQ may not be operated in excess of six (6) months from the
date they are first authorized.
(c) Any person who proposes
to control windblown particulate emissions from truck dump storage areas other than
by enclosure must apply to DEQ for written authorization to utilize alternative
controls. The application must describe in detail the plan proposed to control windblown
particulate emissions and indicate on a plot plan the nearest location of property
not under ownership of the applicant.

(a) The combined particulate
emissions from particleboard plant sources including, but not limited to, hogs,
chippers, and other material size reduction equipment, process or space ventilation
systems, particle dryers, classifiers, presses, sanding machines, and materials
handling systems must not exceed a plant specific average hourly emission rate,
pounds per hour, determined by multiplying the plant production capacity by three
pounds per 1000 square feet. The plant production capacity is the maximum production
in terms of 1,000 square feet on a 3/4 inch basis of finished product for a typical
operating shift divided by the number of hours in the operating shift.
(b) Excepted from subsection
(2)(a) are truck dump and storage areas, fuel burning equipment, and refuse burning
equipment.
(c) Compliance with the average
hourly emission rate is determined by summing the emissions from the affected sources

Hardboard Manufacturing Operations
(1) Truck Dump and Storage Areas:
(a) Every person operating
or intending to operate a hardboard manufacturing plant must enclose all truck dump
and storage areas holding or intended to hold raw materials to prevent windblown
particle emissions from these areas from being deposited upon property not under
the ownership of said person;
(b) The temporary storage
of raw materials outside the regularly used areas of the plant site is prohibited
unless the person who desires to temporarily store such raw materials first notifies
DEQ and receives written approval:
(A) When authorized by DEQ,
temporary storage areas must be operated to prevent windblown particulate emissions
from being deposited upon property not under the ownership of the person storing
the raw materials;
(B) Any temporary storage
areas authorized by DEQ may not be operated in excess of six (6) months from the

in detail the plan proposed to control windblown particulate emissions and indicate
on a plot plan the nearest location of property not under ownership of the applicant.
(2) Other Emission Sources:
(a) For hardboard plants
that did not exist during the baseline period, the combined particulate emissions
from all emissions sources at the plant must not exceed a plant specific hourly
average emission rate, pounds per hour, determined by multiplying the plant production
capacity by one pound per 1,000 square feet of production. The plant production
capacity is the maximum production in terms of 1000 square feet on a 1/8 inch finished
basis for a typical operating shift divided by the number of hours in the operating
shift.
(b) For hardboard plants
that existed during the baseline period, the combined particulate emissions from
the plant must not exceed the lesser of:
(A) A plant specific hourly
average emission rate, pounds per hour, determined by multiplying the plant production
capacity by two pounds per 1,000 square feet of production. The plant production
capacity is the maximum production in terms of 1,000 square feet on a 1/8 inch finished
basis for a typical operating shift divided by the number of hours in the operating
shift, or
(B) The sum of the baseline
emissions rate, pounds per hour, of the press/cooling vent and the lesser of:
(i) The baseline emissions
rate, pounds per hour, from all sources at the plant, excluding the press/cooling
vents; or
(ii) A plant specific hourly
average emission rate, pounds per hour, determined by multiplying the plant production
capacity by one pound per 1,000 square feet of production. The plant production
capacity is the maximum production in terms of 1,000 square feet on a 1/8 inch finished
basis for a typical operating shift divided by the number of hours in the operating
shift.
(c) Excepted from subsections
(a) and (b) are truck dump and storage areas, fuel burning equipment, and refuse
burning equipment.
(d) Compliance with the average
hourly emission rate is determined by summing the emissions from the affected sources
as determined by emission factor calculations or actual emissions data for a 24
hour period divided by 24.
(3) Emissions from Hardboard
Tempering Ovens:
(a) No person may operate
any hardboard tempering oven unless all gases and vapors emitted from said oven
are treated in a fume incinerator capable of raising the temperature of said gases
and vapors to at least 1500° F. for 0.3 seconds or longer except as allowed
by paragraph (b);
(b) Specific operating temperatures
lower than 1500° F. may be approved by DEQ using the procedures in 40 CFR 63.2262
of the NESHAP for Plywood and Composite Wood Products.
