The Clean Air Act contains requirements for monitoring and compliance certification for all major stationary sources of air pollution that receive operating permits under Title V of the Act. Pursuant to these requirements, the U.S. Environmental Protection Agency promulgated regulations and revised existing regulation in 1997. The new regulations implement compliance assurance monitoring (CAM) and require owners or operators of such sources to meet specific criteria established in the rule.
The monitoring focuses on emissions units that rely on pollution control device equipment in order to achieve compliance with applicable standards. The CAM rule is located in Title 40, Chapter 1, of the Code of Federal Regulations, Part 64.
