Environmental Protection Agency June 15, 2018 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve an Arizona state implementation plan (SIP) revision for attaining the 1-hour sulfur dioxide (SO2) primary national ambient air quality standard (NAAQS or ``standard'') for the Miami SO2 nonattainment area (NAA). This SIP revision (hereinafter called the ``Miami SO2 Plan'' or ``Plan'') includes Arizona's attainment demonstration and other elements required under the Clean Air Act (CAA or ``Act''). In addition to an attainment demonstration, the Plan addresses the requirement for meeting reasonable further progress toward attainment of the NAAQS, reasonably available control measures and reasonably available control technology, base-year and projected emission inventories, enforceable emissions limitations and control measures, and contingency measures. The EPA proposes to conclude that Arizona has appropriately demonstrated that the Plan provides for attainment of the 2010 1-hour primary SO2 NAAQS in the Miami SO2 NAA by the attainment date of October 4, 2018 and that the Plan meets the other applicable requirements under the CAA.

The Environmental Protection Agency (EPA) will kick off the Per- and Polyfluoroalkyl Substances (PFAS) community engagements with a two-day event in Exeter, New Hampshire. The goal of the event is to allow the EPA to hear directly from New England communities to understand ways the Agency can best support the work that is being done at the state, local, and tribal level. For more information on the event, visit the EPA's PFAS website: https://www.epa.gov/pfas/pfas- community-engagement. During the recent PFAS National Leadership Summit, the EPA announced plans to visit communities to hear directly from those impacted by PFAS. This engagement is the next step in the EPA's commitment to address challenges with PFAS. The EPA anticipates that the community engagements will provide valuable insight for the agency's efforts moving forward. For more information, go to the SUPPLEMENTARY INFORMATION section of this notice.

The Environmental Protection Agency (EPA) proposes to approve a state implementation plan (SIP) revision submitted by the Commonwealth of Pennsylvania on May 2, 2018. The purpose of this SIP revision is to remove from the Pennsylvania SIP, the Commonwealth's existing requirements limiting summertime gasoline volatility to 7.8 pounds per square inch (psi) Reid Vapor Pressure (RVP) in seven counties in the Pittsburgh-Beaver Valley Area. In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal 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 relevant to this action, the direct final rule will be withdrawn and all public comments received will be addressed in a 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.

On June 23, 2016, the Environmental Protection Agency (EPA) promulgated its final response to petitions for reconsideration of the final new source performance standards (NSPS) and emission guidelines (EG) for commercial and industrial solid waste incineration (CISWI) units that were promulgated on March 21, 2011, and revised after reconsideration on February 7, 2013. Following promulgation of the June 2016 final action, the EPA received requests from industry stakeholders and implementing agencies to clarify various issues with implementation of the standards. In addition, the EPA identified certain testing and monitoring issues and inconsistencies within the rules that required further clarification or correction. To address these issues, the EPA is proposing amendments to several provisions of the 2016 CISWI NSPS and EG. In addition, the EPA identified regulatory provisions that require clarification and editorial correction to address inconsistencies and errors in the final rules. If finalized, the proposed amendments will provide clarity and address implementation issues in the final CISWI NSPS and EG. The proposed revisions will not have any environmental, energy, or economic impacts, if finalized.
