Title32 - Emission Standards

Section 32-001 Definitions
See Title 12, Definitions.

Section 32-005 Highest and Best Practicable Treatment and Control Required
	1. As specified in 32-006 through 32-009 and subsections 2 through 6 of this section, the highest and best practicable treatment and control of air contaminant emissions shall in every case be provided so as to maintain overall air quality at the highest possible levels, and to maintain contaminant concentrations, visibility reduction, odors, soiling and other deleterious factors at the lowest possible levels. In the case of new sources of air contamination, particularly those located in areas with existing high-level air quality, the degree of treatment and control provided shall be such that degradation of existing air quality is minimized to the greatest extent possible.
	2. A source shall be deemed to be in compliance with subsection 1 of this section if the source is in compliance with all other applicable emission standards and requirements contained in LRAPA Titles 32 through 51 and OAR Divisions 28 and 32, including but not limited to requirements applicable to:
		A. specific pollutants in Title 32;
		B. specific existing and new source categories in Title 33;
		C. hazardous air pollutants in OAR 340-32;
		D. control requirements and operational and maintenance requirements in sections 32-007 through 32-009; and
		E. review of new major sources and major modifications in Title 38.
	3. The Authority may adopt additional rules as necessary to ensure that the highest and best practicable treatment and control is provided as specified in subsection 1 of this section. Such rules may include, but are not limited to, the following requirements:
		A. Applicable to a source category, pollutant or geographic area of Lane County;
		B. Necessary to protect public health and welfare for air contaminants that are not otherwise regulated by the Authority; or
		C. Necessary to address the cumulative impact of sources on air quality.
	4. The Authority encourages the owner or operator of a source to further reduce emissions from the source beyond applicable control requirements where feasible.
	5. Nothing in sections 32-005 through 32-009 revokes or modifies any existing permit term or condition unless or until the Authority revokes or modifies the term or condition by a permit revision. Adoption of 32-005 is not intended to withdraw authority for application of any existing policy for new sources of toxic and hazardous air pollutants to a federal operating permit program source until the effective date of the program.
	6. Compliance with a specific emission standard in these rules does not preclude the required compliance with any other applicable emission standard.

Section 32-006 Pollution Prevention
The owner or operator of a source is encouraged to take into account the overall impact of the control methods selected, considering risks to all environmental media and risks from all affected products and processes. The owner or operator of a source is encouraged, but not required, to utilize the following hierarchy in controlling air contaminant emissions:

1. Modify the process, raw materials or product to reduce the toxicity and/or quantity of air contaminants generated;
2. Capture and reuse air contaminants;
3. Treat to reduce the toxicity and/or quantity of air contaminants released; or
4. Otherwise control emissions of air contaminants

Section 32-009 Additional Control Requirements for Stationary Sources of Air Contaminants
The Authority shall establish control requirements in addition to otherwise applicable requirements by permit, if necessary, as specified in section 1 through 5 of this section.

1. Requirements shall be established to prevent violation of an Ambient Air Quality Standard caused or projected to be caused substantially by emissions from the source as determined by modeling, monitoring or a combination thereof. For existing sources, the violation of an Ambient Air Quality Standard shall be confirmed by monitoring conducted by the Authority.
2. Requirements shall be established to prevent significant impairment of visibility in Class I areas caused or projected to be caused substantially by a source as determined by modeling, monitoring or a combination thereof. For existing sources, the visibility impairment shall be confirmed by monitoring conducted by the Authority.
3. A requirement applicable to major source shall be established if it has been adopted by EPA but has not otherwise been adopted by the EQC or the LRAPA Board.
4. An additional control requirement shall be established if requested by the owner or operator of a source.
5. Additional controls may be required to achieve air contaminant reduction as part of a State Implementation Plan

Section 32-015Particulate Matter Weight Standards
Notwithstanding emission limits of Sections 32-020 and 32-030, particulate emissions shall not exceed:

1. 0.2 grain per standard dry cubic foot for any air contaminant source constructed or modified prior to June 1, 1970; or
2. 0.1 grain per standard dry cubic foot for any air contaminant source installed, constructed or modified after June 1, 1970

Section 32-020 Particulate Matter Weight Standards - Existing Combustion Sources
The maximum allowable emission of particulate matter from any existing combustion source (sources installed, constructed or modified prior to June 1, 1970) shall not exceed 0.2 grain per cubic foot of exhaust gas, adjusted to 50 percent excess air or calculated to 12 percent carbon dioxide.

Section 32-030 Particulate Matter Weight Standards - New Combustion Sources
The maximum allowable emission of particulate matter from any new combustion source (sources installed, constructed or modified after June 1, 1970) shall not exceed 0.1 grain per cubic foot of exhaust gas, adjusted to 50 percent excess air or calculated to 12 percent carbon dioxide.

Section 32-045 Process Weight Emission Limitations

1. The maximum allowable emissions of particulate matter for specific processes shall be a function of process weight and shall be determined from Table 1
2. The maximum allowable emissions of particulate matter from hot mix asphalt plants shall be determined from Table 1 except that the maximum allowable particulate emissions from processes greater than 60,000 pounds per hour shall be limited to 40 pounds per hour.

Section 32-055 Particulate Matter Size Standard
No person shall cause or permit the emissions of any particulate matter which is greater than 250 microns in size if such particulate matter does or will deposit upon the real property of another person.

GASEOUS EMISSION LIMITATIONS

Section 32-075 Federal Acid Rain Regulations Adopted by Reference

1. 40 CFR Part 72 (July 1, 1994) is by this reference adopted and incorporated herein, for purposes of implementing an acid rain program that meets the requirements of Title IV of the Clean Air Act. The term "permitting authority" shall mean the Lane Regional Air Protection Agency, and the term "Administrator" shall mean the Administrator of the United States Environmental Protection Agency
2. If the provisions or requirements of 40 CFR Part 72 conflict with or are not included in OAR 340-28-2100 through 340-28-2740, the Part 72 provisions and requirements shall apply and take precedence.

Section 32-090 Other Emissions

1. No person shall discharge from any source whatsoever such quantities of air contaminants which cause injury or damage to any persons, the public, business or property. Such determination is to be made by the Authority.
2. No person shall cause or permit emission of water vapor if the water vapor causes or tends to cause detriment to the health, safety or welfare of any person or causes, or tends to cause damage to property or business.

Section 32-095 Fugitive Emissions
See LRAPA Title 48 for rules pertaining to fugitive emissions.

Section 32-104 Temporary PSD Increment Allocation (Moved to Title 34, 11/10/94)

Interpolation and extrapolation of emissions above a process weight of 60,000 pounds per hour shall be accomplished by use of this equation:
E = (55.0 x P^0.11) - 40, where P = process weight in tons per hour and
E = emission rate in pounds per hour.
