Environmental Protection Agency May 10, 2021 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of South Dakota on January 3, 2020 that revises the Administrative Rules of South Dakota (ARSD), Air Pollution Control Program, updating the chapter pertaining to definitions. The EPA is taking this action pursuant to the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing to approve, or conditionally approve, all or portions of the state implementation plan (SIP) revision submitted by the State of California to meet Clean Air Act requirements for the 2008 8-hour ozone national ambient air quality standards (NAAQS or ``standards'') in the West Mojave Desert ozone nonattainment area. The SIP revision addresses the nonattainment area requirements for the 2008 8-hour ozone NAAQS, including the requirements for an emissions inventory, emissions statements, attainment demonstration, reasonable further progress, reasonably available control measures, contingency measures, and motor vehicle emissions budgets. The EPA is proposing to approve the SIP revision as meeting all the applicable ozone nonattainment area requirements, except for contingency measures, for which we are proposing conditional approval.

The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), Notice of Supplemental Distribution of a Registered Pesticide Product (EPA ICR Number 0278.13, OMB Control Number 2070-0044) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. This is a proposed extension of the ICR, which is currently approved through February 28, 2021. EPA previously provided a 60-day public review opportunity via the Federal Register on August 17, 2020. With this submission, EPA is providing an additional 30-days for public review. A fuller description of the ICR is given below, including its estimated burden and cost to the public. An Agency may not conduct or sponsor and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number.

This notice announces the Environmental Protection Agency's (EPA) approval of the State of New Hampshire's request to revise/modify certain of its EPA-authorized programs to allow electronic reporting.

The Environmental Protection Agency (EPA) is publishing for public review and comment a draft total maximum daily load (TMDL) for sediment in the Indian Creek Watershed in Montgomery County, Pennsylvania pursuant to Section 303(d) of the Clean Water Act. To assist the public in their understanding of the draft TMDL and provide an overview of the TMDL process, EPA invites the public to attend a virtual public meeting. Section 303(d) of the Clean Water Act requires that each state identify those waters (called ``water quality-limited segments'') for which existing technology-based pollution controls are not stringent enough to attain or maintain state water quality standards and for which total maximum daily loads (TMDLs) must be developed. A TMDL establishes a target for the total load of a particular pollutant that a waterbody can assimilate without exceeding water quality standards and divides that load into wasteload allocations, given to point sources, load allocations, given to nonpoint sources and natural background, and a margin of safety, which takes into account any uncertainty. TMDLs provide a framework to achieve water quality standards in a watershed and inform other federal and state programs of the necessary pollutant reductions needed by sources to achieve those standards. The draft TMDL report and information pertaining to the virtual public meeting is available from EPA Region 3's website at: https://www.epa.gov/tmdl/revised-sediment- tmdl-indian-creek-watershed-montgomery-county-pennsylvania.

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Arizona State Implementation Plan (SIP). This revision concerns emissions of sulfur dioxide (SO2) from the copper smelter in Miami, Arizona. We are approving the rescission of two Arizona Department of Environmental Quality (ADEQ) Arizona Administrative Code (A.A.C.) provisions from the Arizona SIP that are no longer needed to regulate this emission source under the Clean Air Act (CAA or the ``Act'').

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving the State Implementation Plan (SIP) submittal from Louisiana submitted on November 4, 2020 for the 2015 ozone, as well as the 2006 PM2.5, 2008 ozone, 2010 nitrogen dioxide, 2010 sulfur dioxide and the 2012 PM2.5 National Ambient Air Quality Standards. This submittal addresses how the existing SIP contains adequate provisions prohibiting emissions which interfere with required measures in any other State to protect visibility with respect to the 2015 ozone NAAQS as well as the 2006 PM2.5, 2008 ozone, 2010 nitrogen dioxide, 2010 sulfur dioxide and the 2012 PM2.5 NAAQS.

The Environmental Protection Agency (EPA) is approving state implementation plan (SIP) revisions submitted by State of Utah on November 5, 2019. The revisions amend R307-204 to meet the requirements set forth in Utah's 2019 House Bill (H.B.) 155. This action is being taken under section 110 of the Clean Air Act (CAA).
