I - SIP
When EPA establishes a new National Ambient Air Quality Standard (NAAQS) as part of the Clean Air Act, all states are required to develop and submit an infrastructure plan, or I-SIP.
These plans have several parts to them, also known as “elements.” A basic I-SIP includes the state laws, rules, emission controls, governmental structure, and other resources—or the basic “infrastructure”—to meet the air quality standards statewide.
I-SIP elements include provisions for:
- Control measures
- Ambient air quality monitoring
- Prevention of emissions transport outside the state
- Source monitoring
- Emergency power
- Visibility protection
- Air quality modeling
