Idaho Air Fact Sheet

1. What air regulations does the state of Idaho follow?

• Air regulations in the state of Idaho assures compliance with federal and state health-based air quality standards by monitoring air quality and collecting data; developing and issuing permits; and coordinating air quality improvement efforts among communities, citizen groups, businesses, industries, other state agencies, and the U.S. Environmental Protection Agency (EPA). Idaho regulates its own state list of TAPs, which includes: screening levels; acceptable ambient concentrations for non-carcinogen and carcinogens. It is also used for the emission inventory. See:Rules for the Control of Air Pollution in Idaho (see p142). http://adm.idaho.gov/adminrules/rules/idapa58/0101.pdf

2. Which state organization manages air pollution regulations?

• Air Quality Division: The Idaho Department of Environmental Quality (DEQ)http://www.deq.idaho.gov/about/deq_purpose.cfm houses theAir Quality Division. http://www.deq.idaho.gov/about/divisions/air.cfm. The Air Quality Division efforts are designed to assure compliance with federal and state health-based air quality standards.

3. What are the responsibilities of the Air Quality Division?

• Monitor and Assess Air Quality: Routinely assesses outdoor (ambient) air quality to satisfy federal regulatory requirements and scientifically determine the quality of Idaho's airsheds; http://www.deq.idaho.gov/air/data_reports/monitoring/overview.cfm
•  Issue permits and conduct inspections : Issue permits to ensure compliance with all state and federal air pollution control rules, which are designed to protect public health and the environment; http://www.deq.idaho.gov/air/permits_forms/permitting/overview.cfm
• Coordinate air quality improvement efforts: Idaho's TAP Program is a stand-alone risk-based program that regulates approximately 350 pollutants determined by their nature to be toxic to human or animal life or vegetation; http://www.deq.idaho.gov/air/prog_issues/toxics/overview.cfm
• Air Quality: Programs and Issues: Address air pollutants; assistance, burning and smoke management, climate change, monitoring, permitting, compliance and enforcement and planning; http://www.deq.idaho.gov/air/prog_issues.cfm

4. Where are the rules found?

• Toxic Air Pollutants (TAPs) emission limits: TAPS from industrial sources are limited by acceptable ambient concentrations (AACs) for carcinogenic and non-carcinogenic pollutants and by screening emission levels (ELs) for non-carcinogens. AACs are the maximum concentration levels allowed in the outside air from a pollution source or sources under construction or modification. AACs for non-carcinogens are 24-hour averages. These levels can be found in IDAPA 58.01.01.585. Acceptable ambient concentrations for carcinogens (AACCs) are annual averages. These levels can be found in IDAPA 58.01.01.586.
•   Emission Levels (ELs): ELs are stack-based emission levels based on pounds of each pollutant emitted per hour. Emission levels for non-carcinogens can be found in IDAPA 58.01.01.585, while emission levels for carcinogens can be found in IDAPA 58.01.01.586.
