Start Preamble


Environmental Protection Agency (EPA).


Proposed rule.


The Environmental Protection Agency (EPA) is proposing to determine that the Delaware County, Pennsylvania moderate nonattainment area (the Delaware County Area) has attained the 2012 annual fine particulate matter (PM2.5) national ambient air quality standard (NAAQS). This determination of attainment, also known as a clean data determination, is based upon quality assured, certified, and complete ambient air monitoring data showing that this area has monitored attainment of the 2012 annual PM2.5 NAAQS based on the 2013-2015 data available in EPA's Air Quality System (AQS) database. If this determination is finalized, the requirements for the Delaware County Area to submit an attainment demonstration, associated reasonably available control measures (RACM), a reasonable further progress (RFP) plan, contingency measures, and other planning state implementation plan (SIP) revisions related to attainment of the standard shall be suspended for so long as the area continues to meet the 2012 annual PM2.5 NAAQS. This action is being taken under the Clean Air Act (CAA).

In the Final Rules section of this Federal Register, EPA is making this determination of attainment as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in Start Printed Page 89890a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.


Comments must be received in writing by January 12, 2017.
