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 vent" means the vent serving the vessel used to dissolve the molten smelt produced 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 with the exception of references to Total Reduced Sulfur.

More Restrictive Emission Limits

The DEQ may establish more restrictive emission limits than the numerical emission standards contained in OAR 340-234-0210 and maximum allowable daily mill site emission limits in kilograms or pounds per day for an individual mill upon a finding by DEQ that:

(1) The individual mill is 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

(3) Other rules which are more stringent apply.

340-234-0240

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.

(4) All daily average opacities for each recovery furnace stack where transmissometers are utilized.

(5) All six-minute average opacities from each recovery furnace stack that exceeds 35 percent.

(6) Daily average kilograms of particulate per equivalent metric ton (pounds of particulate per equivalent ton) of pulp produced for each recovery furnace stack.

(7) Unless otherwise approved in writing, all periods of non-condensable gas bypass must be reported.

(8) Each kraft mill must furnish, upon request of DEQ, such other pertinent data as DEQ may require to evaluate the mill's emission control program.

(9) Monitoring data reported must reflect actual observed levels corrected for oxygen, if required, and analyzer calibration.

(10) Oxygen concentrations used to correct regulated pollutant data must reflect oxygen concentrations at the point of measurement of regulated pollutants.

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.

NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.
