Introduction to Air Quality Planning (SIP 101)

This course is designed to introduce new air program staff to the big picture of air quality management and planning. Targeted at all work areas in an air agency, this course will provide context for where each area fits into the overall SIP and air quality management process.

The next SIP101 course in the LADCO region is scheduled for May 15 and 16 at the EPA Region V offices in Chicago. Please contact the LADCO Office Manager if you’re interested in attending.


Course objectives

This course will introduce students to State Implementation Plans (SIPs), the SIP processes, present the timelines for developing SIPs, and show how the different components of an air agency fit into the overall SIP process. The course will provide the regulatory background on SIPs and give attendees an understanding of the different types and structures of SIPs. The attendees will come out of this course with an understanding of how SIPs are used in the context of air quality management.


A combination of classroom and distance learning webinars are used to present the materials for this course. SIP 101 starts with an intensive 1 day (two 1/2 days), classroom course taught by experienced MJO, state, and EPA air agency staff. The classroom course will introduce attendees to the terminology and major topic areas of air quality management and SIPs.

The classroom course is followed up by a series of 1-hour (40 min presentation + 20 min Q&A) webinars on specific SIP-related topics. These webinars give attendees the opportunity to take deeper dives into key areas of the air quality management process.
