The CAA Amendments of 1990 introduced large-scale changes to the CAA, including provisions addressing global air pollution. Which topic is addressed in Title III?

• A. operating permits
• B. stratospheric ozone protection
• C. air toxics
• D. mobile sources

Answer: (C)

The main idea here is about how the 1990 amendments organized different pollution controls. Title III is the part that focuses on air toxics, the hazardous air pollutants that pose significant health risks. It established a regulatory program to limit these pollutants from stationary sources, mainly through the National Emission Standards for Hazardous Air Pollutants (NESHAPs) and related risk-based reviews. This is distinct from other titles: operating permits are part of the permitting framework under Title V, mobile sources are addressed under Title II, and protections for stratospheric ozone (a global issue) are under Title VI.
