Environmental Protection Agency September 6, 2019 – Federal Register Recent Federal Regulation Documents

Notice is hereby given that the State of Mississippi is revising its approved Public Water System Supervision Program. Mississippi has adopted drinking water regulations for the Revised Total Coliform Rule. The Environmental Protection Agency (EPA) has determined that Mississippi's regulations are no less stringent than the federal rule and the revision otherwise meets applicable Safe Drinking Water Act requirements. Therefore, EPA intends to approve this revision to the State of Mississippi's Public Water System Supervision Program.

The Environmental Protection Agency (EPA) is taking action under the Clean Air Act (CAA) on Indiana's November 27, 2017 State Implementation Plan (SIP) submittal addressing regional haze. This action is based on EPA's previous determination that a state's implementation of the Cross-State Air Pollution Rule (CSAPR) program continues to meet the criteria of the Regional Haze Rule (RHR) to qualify as an alternative to the application of Best Available Retrofit Technology (BART). EPA is taking several related actions. First, EPA is approving the portion of Indiana's November 27, 2017 SIP submittal seeking to change reliance from the Clean Air Interstate Rule (CAIR) to CSAPR for certain regional haze requirements. EPA is also converting EPA's limited approval/limited disapproval of Indiana's regional haze SIP to a full approval and withdrawing the Federal Implementation Plan (FIP) provisions that address the limited disapproval. Finally, EPA is approving the visibility prong (``prong 4'') of Indiana's infrastructure SIP submittals for the 2006 24-hour and 2012 annual fine particulate matter (PM2.5), 2010 nitrogen dioxide (NO2), and 2010 sulfur dioxide (SO2) National Ambient Air Quality Standards (NAAQS) and converting EPA's disapproval of the visibility portion of Indiana's infrastructure SIP submittal for the 2008 ozone NAAQS to an approval.

The Environmental Protection Agency (EPA) is taking final action to approve a Missouri State Implementation Plan (SIP) revision submission received on February 15, 2019. The submission revises a Missouri SIP approved regulation that establishes alternate monitoring methods for certifying compliance and alternate methods to establish whether a violation has occurred at a source. These revisions are administrative in nature and do not impact the stringency of the SIP or air quality. Approval of these revisions will ensure consistency between state and federally-approved rules. The EPA's approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).

The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Plywood and Composite Wood Products (PCWP) to address the results of the residual risk and technology review (RTR) that the EPA is required to conduct under the Clean Air Act (CAA). The EPA is proposing to amend provisions addressing periods of startup, shutdown and malfunction (SSM); add provisions regarding electronic reporting; add repeat emissions testing requirements; and make technical and editorial changes. The EPA is proposing these amendments to improve the effectiveness of the NESHAP. While the proposed amendments would not result in reductions in emissions of hazardous air pollutants (HAP), this action, if finalized, would result in improved monitoring, compliance, and implementation of the rule.
