The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision submitted by the State of Delaware. This revision pertains to reasonably available control technology (RACT) requirements under the 2008 8-hour ozone national ambient air quality standard (NAAQS). Delaware's submittal for RACT for the 2008 ozone NAAQS includes (1) certification that, for certain categories of sources, RACT controls approved by EPA into Delaware's SIP for previous ozone NAAQS are based on currently available technically and economically feasible controls and continue to represent RACT for 2008 8-hour ozone NAAQS implementation purposes; (2) the adoption of new or more stringent regulations or controls that represent RACT control levels for certain other categories of sources; and (3) a negative declaration that certain categories of sources do not exist in Delaware. This action is being taken under the Clean Air Act (CAA).
The agency’s own summary, as published.
