The Environmental Protection Agency published a notice December 7 announcing that it will propose national emission standards for hazardous air pollutants for brick and structural clay product manufacturing facilities by August 30. The agency agreed to undertake the rulemaking after the Sierra Club filed a complaint charging that the agency failed to meet Clean Air Act obligations to set the standards by November 15, 2000; the agency will finalize the rule no later than July 31, 2014.
