Riepilogo

On February 12, 2013, the Environmental Protection Agency (EPA) finalized amendments to the national emission standards for the control of hazardous air pollutants (NESHAP) from the new and existing Portland cement manufacturing industry at major sources of hazardous air pollutants (HAP). Subsequently, the EPA has become aware of certain minor technical errors in those amendments, and is, accordingly, proposing amendments and technical corrections to the final rule. In addition, the EPA plans to remove rule provisions establishing an affirmative defense in the final technical correction rule.
