Ambient Air Quality Standards

340-202-0050

Purpose and Scope of Ambient Air Quality Standards

(1) An ambient air quality standard is an established concentration, exposure time, and frequency of occurrence of an air contaminant or multiple contaminants in the ambient air that must not be exceeded. The ambient air quality standards set forth in OAR 340-202-0050 through 340-202-0130 were established to protect both public health and public welfare.

(2) Ambient air quality standards are not generally used to determine the acceptability or unacceptability of emissions from a specific source of air contamination. More commonly, the measured ambient air quality is compared with the ambient air quality standards to determine the adequacy or effectiveness of emission standards for all sources in a general area. However, if a source or combination of sources are singularly responsible for a violation of ambient air quality standards in a particular area, it may be appropriate to impose emission standards that are more stringent than those otherwise applied to the class of sources involved. Similarly, proposed construction of new sources or expansions of existing sources, that may prevent or interfere with the attainment and maintenance of ambient air quality standards are grounds for issuing an order prohibiting such proposed construction as authorized by ORS 468A.055 and pursuant to OAR 340-210-0205 through 340-210-0250, and OAR 340-218-0190. No source may cause or contribute to a new violation of an ambient air quality standard or PSD increment even if the single source impact is less than the significant impact level.

(3) In adopting the ambient air quality standards in this division, the EQC recognizes that one or more of the standards are currently being exceeded in certain parts of the state. It is hereby declared to be the policy of the EQC to achieve, by application of a timely but orderly program of pollution abatement, full compliance with ambient air quality standards throughout the state at the earliest possible date.

Prevention of Significant Deterioration Increments

340-202-0200

General

(1) The purpose of OAR 340-202-0200 through 340-202-0220 is to implement a program to prevent significant deterioration of air quality in the State of Oregon as required by the federal Clean Air Act Amendments of 1977.

(2) DEQ will review the adequacy of the SIP on a periodic basis and within 60 days of such time as information becomes available that an applicable increment is being violated. Any SIP revision resulting from the reviews will be subject to the opportunity for public hearing in accordance with procedures established in the SIP.

DIVISION 206

AIR POLLUTION EMERGENCIES

340-206-0010

Introduction

OAR 340-206-0030, 340-206-0050 and 340-206-0060 are effective within priority I and II air quality control regions (AQCR) as defined in 40 CFR Part 51, subpart H (1995), when the AQCR contains a nonattainment area listed in 40 CFR Part 81. All other rules in this division are equally applicable to all areas of the state. Notwithstanding any other regulation or standard, this division is designed to prevent the excessive accumulation of air contaminants during periods of atmospheric stagnation or at any other time, which if allowed to continue to accumulate unchecked could result in concentrations of these contaminants reaching levels which could cause significant harm to the health of persons. This division establishes criteria for identifying and declaring air pollution episodes at levels below the level of significant harm and are adopted pursuant to the requirements of the FCAA as amended and 40 CFR Part 51.151. Levels of significant harm for various regulated pollutants listed in 40 CFR Part 51.151 are:

(1) For sulfur dioxide (SO2) - 1.0 ppm, 24-hour average.

(2) For particulate matter

(a) PM10 - 600 micrograms per cubic meter, 24-hour average.

(b) PM2.5 -- 350.5 micrograms per cubic meter, 24-hour average.

(3) For carbon monoxide (CO):

(a) 50 ppm, 8-hour average.

(b) 75 ppm, 4-hour average.

(4) For ozone (O3) -- 0.6 ppm, 2-hour average.

(5) For nitrogen dioxide (NO2):

(a) 2.0 ppm, 1-hour average.

(b) 0.5 ppm, 24-hour average.

Episode Stage Criteria for Air Pollution Emergencies

Three stages of air pollution episode conditions and a pre-episode standby condition are established to inform the public of the general air pollution status and provide a management structure to require preplanned actions designed to prevent continued accumulation of regulated pollutants to the level of significant harm. The three episode stages are: Alert, Warning, and Emergency. DEQ is responsible to enforce the provisions of this division which requires actions to reduce and control emissions during air pollution episode conditions. An air pollution alert or air pollution warning must be declared by the Director or appointed representative when the appropriate air pollution conditions are deemed to exist. When conditions exist which are appropriate to an air pollution emergency, DEQ must notify the Governor and declare an air pollution emergency pursuant to ORS 468.115. The statement declaring an air pollution Alert, Warning or Emergency must define the area affected by the air pollution episode where corrective actions are required. Conditions justifying the proclamation of an air pollution alert, air pollution warning, or air pollution emergency must be deemed to exist whenever DEQ determines that the accumulation of air contaminants in any place is increasing or has increased to levels which could, if such increases are sustained or exceeded, lead to a threat to the health of the public. In making this determination, DEQ will be guided by the following criteria for each regulated pollutant and episode stage:

(1) "Pre-episode standby" condition, indicates that ambient levels of regulated pollutants are within standards or only moderately exceed standards. In this condition, there is no imminent danger of any ambient regulated pollutant concentrations reaching levels of significant harm. DEQ must maintain at least a normal monitoring schedule but may conduct additional monitoring. An air stagnation advisory issued by the National Weather Service, an equivalent local forecast of air stagnation or observed ambient air levels in excess of ambient air standards may be used to indicate the need for increased sampling frequency. The pre-episode standby condition is the lowest possible air pollution episode condition and may not be terminated.

(2) "Air pollution alert" condition indicates that air pollution levels are significantly above standards but there is no immediate danger of reaching the level of significant harm. Monitoring should be intensified and readiness to implement abatement actions should be reviewed. At the air pollution alert level the public is to be kept informed of the air pollution conditions and of potential activities to be curtailed should it be necessary to declare a warning or higher condition. An air pollution alert condition is a state of readiness. When the conditions in both subsections (a) and (b) are met, an air pollution alert will be declared and all appropriate actions described in Tables 1 and 4 must be implemented:

(a) Meteorological dispersion conditions are not expected to improve during the next 24 or more hours;

(b) Monitored regulated pollutant levels at any monitoring site exceed any of the following:

(A) Sulfur dioxide -- 0.3 ppm -- 24-hour average;

(B) Particulate matter

(i) PM10 -- 350 micrograms per cubic meter (ug/m3) -- 24-hour average;

(ii) PM2.5 -- 140.5 micrograms per cubic meter (ug/m3) -- 24-hour average;

(D) Ozone -- 0.2 ppm -- 1-hour average;

(E) Nitrogen dioxide:

(i) 0.6 ppm -- 1-hour average; or

(ii) 0.15 ppm -- 24-hour average.

(3) "Air pollution warning" condition indicates that pollution levels are very high and that abatement actions are necessary to prevent these levels from approaching the level of significant harm. At the air pollution warning level substantial restrictions may be required limiting motor vehicle use and industrial and commercial activities. When the conditions in both subsections (a) and (b) are met, an air pollution warning will be declared by DEQ and all appropriate actions described in Tables 2 and 4 must be implemented:

(a) Meteorological dispersion conditions are not expected to improve during the next 24 or more hours;

(b) Monitored regulated pollutant levels at any monitoring site exceed any of the following:

(A) Sulfur dioxide -- 0.6 ppm -- 24-hour average;

(B) Particulate matter

(i) PM10 -- 420 ug/m3 -- 24-hour average;

(ii) PM2.5 -- 210.5 ug/m3 -- 24-hour average;

(D) Ozone -- 0.4 ppm -- 1-hour average;

(E) Nitrogen dioxide:

(i) 1.2 ppm -- 1-hour average; or

(ii) 0.3 ppm -- 24-hour average.

(4) "Air pollution emergency" condition indicates that regulated pollutants have reached an alarming level requiring the most stringent actions to prevent these levels from reaching the level of significant harm to the health of persons. At the air pollution emergency level extreme measures may be necessary involving the closure of all manufacturing, business operations and vehicle traffic not directly related to emergency services. Pursuant to ORS 468.115, when the conditions in both subsections (a) and (b) are met, an air pollution emergency will be declared by DEQ and all appropriate actions described in Tables 3 and 4 must be implemented:

(a) Meteorological dispersion conditions are not expected to improve during the next 24 or more hours;

(b) Monitored regulated pollutant levels at any monitoring site exceed any of the following:

(A) Sulfur dioxide 0.8 ppm -- 24-hour average;

(B) Particulate matter

(i) PM10 -- 500 ug/m3 -- 2-hour average;

(ii) PM2.5 -- 280.5 ug/m3 -- 2-hour average;

(D) Ozone 0.5 ppm -- 1-hour average;

(E) Nitrogen dioxide:

(i) 1.6 ppm -- 1-hour average; or

(ii) 0.4 ppm -- 24-hour average.

(5) "Termination": Any air pollution episode condition (alert, warning or emergency) established by these criteria may be reduced to a lower condition when the elements required for establishing the higher conditions are no longer observed.

Special Conditions

(1) DEQ must issue an "ozone advisory" to the public when monitored ozone values at any site exceed the ambient air quality standard of 0.12 ppm but are less than 0.2 ppm for a one hour average. The ozone advisory must clearly identify the area where the ozone values have exceeded the ambient air standard and must state that significant health effects are not expected at these levels, however, sensitive individuals may be affected by some symptoms.

(2) Where particulate is primarily soil from windblown dust or fallout from volcanic activity, episodes dealing with such conditions must be treated differently than particulate episodes caused by other controllable sources. In making a declaration of air pollution alert, warning, or emergency for such particulate, DEQ must be guided by the following criteria:

(a) "Air pollution alert for particulate from volcanic fallout or windblown dust" means particulate values are significantly above a standard but the source is a volcanic eruption or dust storm. In this condition there is no significant danger to public health but there may be a public nuisance created from the dusty conditions. It may be advisable under these circumstances to voluntarily restrict traffic volume and/or speed limits on major thoroughfares and institute cleanup procedures. DEQ will declare an air pollution alert for particulate from volcanic fallout or wind-blown dust when particulate values at any monitoring site exceed or are projected to exceed 800 ug/m3 -- 24-hour average and the particulate is primarily from volcanic activity or dust storms, meteorological conditions not withstanding;

(b) "Air pollution warning for particulate from volcanic fallout or windblown dust" means particulate values are very high but the source is volcanic eruption or dust storm. Prolonged exposure over several days at or above these levels may produce respiratory distress in sensitive individuals. Under these conditions staggered work hours in metropolitan areas, mandated traffic reduction, speed limits and cleanup procedures may be required. DEQ will declare an air pollution warning for particulate from volcanic fallout or wind-blown dust when particulate values at any monitoring site exceed or are expected to exceed 2,000 ug/m3 -- 24-hour average and the particulate is primarily from volcanic activity or dust storms, meteorological conditions not withstanding;

(c) "Air pollution emergency for particulate from volcanic fallout or windblown dust" means particulate values are extremely high but the source is volcanic eruption or dust storm. Prolonged exposure over several days at or above these levels may produce respiratory distress in a significant number of people. Under these conditions cleaning procedures must be accomplished before normal traffic can be permitted. An air pollution emergency for particulate from volcanic fallout or wind-blown dust will be declared by the Director, who must keep the Governor advised of the situation, when particulate values at any monitoring site exceed or are expected to exceed 5,000 ug/m3 -- 24-hour average and the particulate is primarily from volcanic activity or dust storms, meteorological conditions notwithstanding.

(3) Termination: Any air pollution condition for particulate established by these criteria may be reduced to a lower condition when the criteria for establishing the higher condition are no longer observed.

(4) Action: Municipal and county governments or other governmental agency having jurisdiction in areas affected by an air pollution alert, warning or emergency for particulate from volcanic fallout or windblown dust must place into effect the actions pertaining to such episodes which are described in Table 4.

Source Emission Reduction Plans

(1) Tables 1, 2, and 3 of this division set forth specific emission reduction measures which must be taken upon the declaration of an air pollution alert, air pollution warning, or air pollution emergency. Any person responsible for a source of air contamination within a Priority I AQCR must, upon declaration of any air pollution episode condition affecting the locality of the air contamination source, take all appropriate actions specified in the applicable table and must take appropriate actions specified in an approved source emission reduction plan which has been submitted and is on file with DEQ.

(2) Any person responsible for the operation of any point source of air pollution which is located in a Priority I AQCR, located within an AQMA or located within a nonattainment area listed in 40 CFR, Part 81, and emits 100 tons or more of any regulated pollutant specified by subsection (a) or (b) must file a Source Emission Reduction Plan (SERP) with DEQ in accordance with the schedule described in section (4). Persons responsible for other point sources of air pollution located in a Priority I AQCR may optionally file a SERP with DEQ for approval. Such plans must specify procedures to implement the actions required by Tables 1, 2, and 3 of this division and must be consistent with good engineering practice and safe operating procedures. Source emission reduction plans specified by this section are mandatory only for those sources which:

(a) Emit 100 tons per year or more of any regulated pollutant for which the nonattainment area, AQMA, or any portion of the AQMA is designated nonattainment; or

(b) Emit 100 tons per year or more of volatile organic compounds when the nonattainment area, AQMA or any portion of the AQMA is designated nonattainment for ozone.

(3) Municipal and county governments or other governmental body having jurisdiction in nonattainment areas where ambient levels of carbon monoxide, ozone or nitrogen dioxide qualify for Priority I ACQR classification, must cooperate with DEQ in developing a traffic control plan to be implemented during air pollution episodes of motor vehicle related emissions. Such plans must implement the actions required by Tables 1, 2 and 3 of this division and must be consistent with good traffic management practice and public safety.

(4) DEQ must periodically review the source emission reduction plans to assure that they meet the requirements of this division. If deficiencies are found, DEQ must notify the persons responsible for the source. Within 60 days of such notice the person responsible for the source must prepare a corrected plan for approval by DEQ. Source emission reduction plans must not be effective until approved by DEQ.

(5) During an air pollution alert, warning or emergency episode, source emission reduction plans required by this rule must be available on the source premises for inspection by any person authorized to enforce the provisions of this division.

Regional Air Pollution Authorities

(1) DEQ and the regional air pollution authorities must cooperate to the fullest extent possible to insure uniformity of enforcement and administrative action necessary to implement this division. With the exception of sources of air contamination where jurisdiction has been retained by DEQ, all persons within the territorial jurisdiction of a regional air pollution authority must submit the source emission reduction plans prescribed in OAR 340-206-0050 to the regional air pollution authority. The regional air pollution authority must submit copies of approved source emission reduction plans to DEQ.

(2) Declarations of air pollution alert, air pollution warning, and air pollution emergency must be made by the appropriate regional authority. In the event such a declaration is not made by the regional authority, the DEQ must issue the declaration and the regional authority must take appropriate remedial actions as set forth in this division.

(3) Additional responsibilities of the regional authorities include, but are not limited to:

(a) Securing acceptable source emission reduction plans;

(b) Measurement and reporting of air quality data to DEQ;

(c) Informing the public, news media, and persons responsible for air contaminant sources of the various levels set forth in this division and required actions to be taken to maintain air quality and the public health;

(d) Surveillance and enforcement of source emission reduction plans.

Can you explain when these are used as “maximum allowable increases” outside of the context of PSD increments? I take it that’s why you don’t want to name this whole rule “PSD Increments”?

This is a funny statement. We can’t require the EPA Administrator to do anything, but this paragraph seems to provide otherwise.

You don’t reference table names anywhere else, so I wouldn’t here. Alternatively, if you want to include the name, I would put it in quotes to indicate that it is a name. Otherwise this doesn’t really make sense—these are not complete sentences.
