      6. No person shall 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 regulation.
      7. Where effective measures are not taken to minimize fugitive emissions, LRAPA 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.
      8. LRAPA may require more restrictive emission limits than provided in Section 33- 060-3.A(2) and (3) for an individual plant upon finding by the Board of Directors that the individual plant is located or is proposed to be located in a special problem area.

  2. Statement of Policy
    Recent technological developments have enhanced the degree of malodorous emissions 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 LRAPA to:
    1. 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, complies with the highest and best practicable treatment requirement.
    2. Require degrees and methods of treatment for major and minor emissions points that will minimize emissions of odorous gases and eliminate ambient odor nuisances.
    3. Require effective monitoring and reporting of emissions and reporting of other data pertinent to air quality or emissions. LRAPA 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.
    4. 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.

EPA methods shall consist of three (3) separate consecutive runs of one hour each, in accordance with the Department Source Test Manual.
    3. Particulate Matter.
      1. Each mill shall sample the recovery furnace(s), lime kiln(s) and smelt dissolving tank vent(s) for particulate emissions, in accordance with the Department Source Test Manual.

Representative sulfur dioxide emissions from each recovery furnace shall be determined at least once each month by the average of three (3) one-hour source tests in accordance with the Department Source Test Manual or from continuous emission monitors. If continuous emission monitors are used, the monitors shall be operated for three consecutive hours, in accordance with the Department CEM Manual.
    5. Combined Monitoring. LRAPA 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 rule 33- 070-3. LRAPA may establish more stringent emission limits for the combined emission stream.
    6. New Source Performance Standards Monitoring. New or modified sources that are subject to the New Source Performance Standards, 40 CFR Part 60, Subpart BB, shall conduct monitoring or source testing as required by Subpart BB.

  7. Reporting
    If required by LRAPA or required by permit, data shall be reported by each mill for each calendar month by the last day of the subsequent month as follows:
    1. Applicable daily average emissions of TRS gases expressed in parts per million of H2S on a dry gas basis with oxygen concentrations, if oxygen corrections are required, for each source included in the approved monitoring program.
    2. Daily average emissions of TRS gases in pounds of total reduced sulfur per equivalent ton of pulp processed, expressed as H2S for each source included in the approved monitoring program.
    3. Maximum daily 3-hour average emissions of SO2 based on all samples collected from the recovery furnace(s), expressed as ppm, dry basis.

    8. Each Kraft mill shall furnish, upon request of LRAPA, such other pertinent data as LRAPA may require to evaluate the mill's emission control program.
    9. Monitoring data reported shall reflect actual observed levels corrected for oxygen, if required, and analyzer calibration.
    10. Oxygen concentrations used to correct pollutant data shall reflect oxygen concentrations at the point of measurement of pollutants.
      (Reserved)
  8. Chronic Upset Conditions
    If LRAPA determines that an upset condition is chronic and correctable by installing new or modified process or control procedures or equipment, a program and schedule to effectively eliminate the deficiencies causing the upset conditions shall be submitted. Such reoccurring upset conditions causing emissions in excess of applicable limits may be subject to civil penalty or other appropriate action.

Section 33-075 Hot Mix Asphalt Plants

  1. Definitions
    1. "Collection Efficiency" means the overall performance of the air cleaning device in terms of ratio of material collected to total input to the collector unless specific size fractions of the contaminant are stated or required.
    2. "Dusts" means minute solid particles released into the air by natural forces or by mechanical processes such as crushing, grinding, milling, drilling, demolishing, shoveling, conveying, covering, bagging, or sweeping.
    3. "Hot mix asphalt plants" means those facilities and equipment which convey or batch load proportioned quantities of cold aggregate to a drier, and heat, dry, screen, classify, measure, and mix the aggregate with asphalt for purposes of paving, construction, industrial, residential, or commercial use.
    4. "Particulate matter" means any matter except uncombined water, which exists as a liquid or solid at standard conditions.
    5. "Portable hot mix asphalt plants" means those hot mix asphalt plants which are designed to be dismantled and are transported from one job site to another job site.
    6. "Process weight by hour" means the total weight of all materials introduced into any specific process which process may cause any discharge into the atmosphere. Solid fuels charged will be considered as part of the process weight, but liquid and gaseous fuels and combustion air will not. The "process weight per hour" will be derived by dividing the total process weight by the number of hours in one complete operation from the beginning of any given process to the completion thereof, excluding any time during which the equipment is idle.
