On May 16, the U.S. Environmental Protection Agency (EPA) said it would postpone implementing new air pollution limits for major source industrial boilers and solid waste incinerators indefinitely while it reconsiders portions of the rules and addresses legal challenges. The stay does not apply to EPA's hazardous air pollutant rule for smaller area source boilers. It was announced by EPA on March 21 that it had issued emissions standards for indus- trial boilers and incinerators, complying with a court order to issue the final rule for National Emission Standards for Hazardous Air Pollutants (NESHAP) for Major Sources: Industrial, Commercial and Institutional Boilers, and Process Heaters.
