On January 31, 2013, EPA issued final amendments to the National Emission Standards for Hazardous Air Pollutants for Major Source: Industrial, Commercial, and Institutional Boilers and Process Heaters (40 CFR part 63, subpart DDDDD). EPA received ten petitions for reconsideration of the final amendments. On August 5, 2013, EPA granted reconsideration on three issues raised in the petitions. The petitions for reconsideration indicated that the public lacked an opportunity to comment on these provisions. Although EPA added these provisions in response to public comments on the proposal, EPA granted reconsideration to provide an opportunity for public comment on these three issues. EPA plans to issue a Federal Register notice announcing our decision to grant reconsideration and soliciting public comment on the three issues. Additionally, the notice announces amendments to clarify implementation issues raised by stakeholders and to make technical corrections.
