On February 7, 2013, EPA issued final amendments to the Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Commercial and Industrial Solid Waste Incineration Units. EPA received seven petitions for reconsideration of the final amendments. On August 5, 2013, EPA granted reconsideration on two issues raised in the petitions: (1) The definition of "CEMS data during startup and shutdown periods;" (2) The PM limit for the waste-burning kiln subcategory. 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 two issues. EPA plans to issue a Federal Register notice announcing our decision to grant reconsideration and soliciting public comment on the two issues noted above. Additionally, EPA is soliciting comment on two newly identified reconsideration issues: 1) establishing a fuel variability factor for the coal-burning energy recovery units subcategory and 2) revision of the definition of kiln.
