Environmental Protection Agency October 5, 2017 – Federal Register Recent Federal Regulation Documents

The U.S. Environmental Protection Agency (EPA) is announcing an extension of the public comment period by 30 days for the Notice of Intent to Establish Voluntary Criteria for Radon Credentialing Organizations.

The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP), Operating Permits Program, and 112(l) program submitted on July 14, 2014, by the State of Nebraska. This action amends the SIP to revise two chapters, ``Definitions'' and ``Operating Permit Modifications; Reopening for Cause''. Specifically, these revisions incorporate by reference the list of organic compounds exempt from the definition of volatile organic compound (VOC) found in the Code of Federal Regulations; notification requirements for the operating permit program are being amended to be consistent with the Federal operating permit program requirements; the definition of ``solid waste'' is being revised by the state, however, because the state's definition is inconsistent with the Federal definition, EPA is not approving this definition into the SIP. Finally, the state is extending the process of ``off-permit changes'' to Class I operating permits. Additional grammatical and editorial changes are being made in this revision. Approval of these revisions will not impact air quality, ensures consistency between the State and Federally-approved rules, and ensures Federal enforceability of the State's rules. In the ``Rules and Regulations'' section of this Federal Register, we are approving these two chapters as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.

The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) revision submitted by the state of Nebraska on November 14, 2011. Nebraska is adding a new chapter titled ``Visibility Protection'' which provides Nebraska authority to implement Federal regulations relating to Regional Haze and Best Available Retrofit Technology (BART). The chapter incorporates by reference EPA's Guidelines for BART Determiniations under the Regional Haze Rule. The revision to the SIP meets the visibility component of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions, which Illinois submitted to EPA on March 2, 2016, and supplemented on August 8, 2016 and May 4, 2017, for attaining the 2010 1-hour sulfur dioxide (SO2) national ambient air quality standard (NAAQS) for the Lemont and Pekin areas. These revisions (herein called the nonattainment plans or plans) include Illinois' attainment demonstration and other elements required under Clean Air Act (CAA) for the two areas. In addition to an attainment demonstration, the plans address: The requirement for meeting reasonable further progress (RFP) toward attainment of the NAAQS; reasonably available control measures and reasonably available control technology (RACM/RACT); emission inventories; and contingency measures. EPA further proposes to conclude that Illinois has demonstrated that the plans' provisions provide for attainment of the 2010 1-hour primary SO2 NAAQS in the Lemont and Pekin areas by the attainment date of October 4, 2018.
