2. The level of the 8-hour NAAQS for carbon monoxide is 9 parts per million (ppm) not to be exceeded more than once per year. 

3. The design values shown here are computed for the latest design value period using Federal Reference Method or equivalent data reported by States, Tribes, 

and local agencies to EPA's Air Quality System (AQS) as of 6/25/2015. Concentrations flagged by States, Tribes, and local agencies as exceptional events (e.g., 

high winds, wildfires, volcanic eruptions, construction) and concurred by the associated EPA Regional Office are not included in the calculation of these design 

values.

Klamath Falls was redesignated to attainment for the 8-hour CO NAAQS on September 20, 2001. In 2005, with the approval of EPA's Region 10 office, the 

Oregon Department of Environmental Quality (ODEQ) discontinued CO monitoring in the Klamath Falls maintenance area after recording values well below 

standard the previous three years. The Region 10 approval of the discontinuation of the Klamath Falls CO monitor requires that the ODEQ periodically reassess 

the need for CO monitoring data to verify compliance with the standard. ODEQ has agreed in their annual network monitoring plan to track CO emission 

inventories every three years to determine if additional CO monitoring is needed. 

Disclaimer: The information listed in this report and in these tables is intended for informational use only and does not constitute a regulatory determination by EPA as 

whether an area has attained a NAAQS. The information set forth in this report has no regulatory effect. To have regulatory effect, a final EPA determination as to 

whether an area has attained a NAAQS or attained a NAAQS as of its applicable attainment date can be accomplished only after rulemaking that provides an opportunity for 

notice and comment. No such determination for regulatory purposes exists in the absence of such rulemaking. This report does not constitute a proposed or 

final rulemaking.

Notes:

1 Area designation as of 5/15/2015.

2. The level of the 1-hour NAAQS for carbon monoxide is 35 parts per million (ppm) not to be exceeded more than once per year. 

3. The design values shown here are computed for the latest design value period using Federal Reference Method or equivalent data reported by States, Tribes, and local agencies to EPA's Air Quality System 

(AQS) as of 6/25/2015. Concentrations flagged by States, Tribes, and local agencies as exceptional events (e.g., high winds, wildfires, volcanic eruptions, construction) and concurred by the associated EPA 

Regional Office are not included in the calculation of these design values.

Notes:

2. The level of the 8-hour NAAQS for carbon monoxide is 9 parts per million (ppm) not to be exceeded more than once per year. 

3. The design values shown here are computed for the latest design value period using Federal Reference Method or equivalent data reported by States, Tribes, and local agencies to EPA's Air Quality 

System (AQS) as of 6/25/2015. Concentrations flagged by States, Tribes, and local agencies as exceptional events (e.g., high winds, wildfires, volcanic eruptions, construction) and concurred by the 

associated EPA Regional Office are not included in the calculation of these design values.

4. EPA and the California Air Resources Board are currently discussing quality assurance issues associated with the 2014 CO data for these monitoring sites - 06-037-9033, 06-071-0001, 06-071-0306. 

Design values from these sites should NOT be considered valid for use in a regulatory context until these issues are resolved.

Notes:

2. The level of the 8-hour NAAQS for carbon monoxide is 9 parts per million (ppm) not to be exceeded more than once per year. 

3. The design values shown here are computed for the latest design value period using Federal Reference Method or equivalent data reported by States, Tribes, and local agencies to EPA's Air Quality System (AQS) as of 6/25/2015. Concentrations flagged by States, Tribes, and local agencies as exceptional events (e.g., high winds, wildfires, volcanic eruptions, construction) and concurred by the associated EPA Regional Office are not included in the calculation of these design values.

4. EPA and the California Air Resources Board are currently discussing quality assurance issues associated with the 2014 CO data for these monitoring sites - 06-037-9033, 06-071-0001, 06-071-0306. Design values from these sites should NOT be considered valid for use in a regulatory context until these issues are resolved.

Notes:

2. The level of the 1-hour NAAQS for carbon monoxide is 35 parts per million (ppm) not to be exceeded more than once per year. 

3. The design values shown here are computed for the latest design value period using Federal Reference Method or equivalent data reported by States, Tribes, and local agencies to EPA's Air Quality System (AQS) as of 6/25/2015. Concentrations flagged by States, Tribes, and local agencies as exceptional events (e.g., high winds, wildfires, volcanic eruptions, construction) and concurred by the associated EPA Regional Office are not included in the calculation of these design values.

4. EPA and the California Air Resources Board are currently discussing quality assurance issues associated with the 2014 CO data for these monitoring sites - 06-037-9033, 06-071-0001, 06-071-0306. Design values from these sites should NOT be considered valid for use in a regulatory context until these issues are resolved.

Notes:

2. The level of the 8-hour NAAQS for carbon monoxide is 9 parts per million (ppm) not to be exceeded more than once per year. 

3. The design values shown here are computed for the latest design value period using Federal Reference Method or equivalent data reported by States, Tribes, and local agencies to EPA's Air 

Quality System (AQS) as of 6/25/2015. Concentrations flagged by States, Tribes, and local agencies as exceptional events (e.g., high winds, wildfires, volcanic eruptions, construction) and 

concurred by the associated EPA Regional Office are not included in the calculation of these design values.

4. EPA and the California Air Resources Board are currently discussing quality assurance issues associated with the 2014 CO data for these monitoring sites - 06-037-9033, 06-071-0001, 06-071-

0306. Design values from these sites should NOT be considered valid for use in a regulatory context until these issues are resolved.

Notes:

2. The level of the 1-hour NAAQS for carbon monoxide is 35 parts per million (ppm) not to be exceeded more than once per year. 

3. The design values shown here are computed for the latest design value period using Federal Reference Method or equivalent data reported by States, Tribes, and local agencies to EPA's Air Quality System 

(AQS) as of 6/25/2015. Concentrations flagged by States, Tribes, and local agencies as exceptional events (e.g., high winds, wildfires, volcanic eruptions, construction) and concurred by the associated EPA 

Regional Office are not included in the calculation of these design values.

4. EPA and the California Air Resources Board are currently discussing quality assurance issues associated with the 2014 CO data for these monitoring sites - 06-037-9033, 06-071-0001, 06-071-0306. Design 

values from these sites should NOT be considered valid for use in a regulatory context until these issues are resolved.
