Clean Air Act Stationary Sources and Hazardous Air Pollutants

This lesson will introduce you to the technology-based emissions limitations that apply to stationary sources regulated under the Clean Air Act that emit hazardous air pollutants (HAPs). It can act as an introduction to the subject, or you can use this lesson as part of your review of Clean Air Act stationary source regulations at the end of your studies of the Clean Air Act or before your final exam.

This lesson assumes that you already understand the differences between Clean Air Act stationary sources and Clean Air Act mobile sources. If this distinction is unfamiliar to you, you should complete the lesson entitled "Regulated Sources Under the Clean Air Act" before completing this lesson.

Learning Outcomes

On completion of the lesson, the student will be able to:

1. Explain section 112 of the Clean Air Act that governs the emissions standards for stationary sources of hazardous air pollutants (HAPS).
2. Define "stationary source" for purposes of section 112.
3. Discuss what a "major source" of HAPs is for purposes of section 112 and what requirements apply to such major sources.
4. Analyze what an "area source" of HAPs is for purposes of section 112 and what requirements apply to such areas sources.
