Development of Specific Elements for Each of the Major SIP Types for Lead (Pb)
Infrastructure SIP
An infrastructure SIP, or i-SIP, is a requirement for all states, regardless of designation. Even areas in attainment must demonstrate what controls they will continue to use and regulate in order to remain in attainment.
Nonattainment New Source Review SIP
- EPA's New Source Review (NSR) program requires stationary sources of air pollution to get permits before construction starts:
- Search the NSR Policy and Guidance Document Index (hint: use the Filter box at the top right of the index to search titles by keyword)
- Startup, shutdown, and malfunction (SSM) emissions
Nonattainment area SIP, a.k.a. attainment demonstration SIP
- If an area is designated as nonattainment, the state must develop an additional SIP detailing the path to attainment. The SIP will require different elements depending on how far the area is from being able to reach attainment.
