The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) revisions submitted by the State of South Carolina, through the South Carolina Department of Health and Environmental Control (SCDHEC or Department), on April 24, 2020. The SIP revisions update the State's Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NNSR) regulations. Specifically, the SIP revisions add and update several definitions for consistency with the Federal regulations, update public participation requirements for PSD, clarify the applicability of ``source impact analysis'' for PSD, add an emissions offset banking provision for NNSR, and make administrative updates, such as typographical corrections and renumbering. Finally, the changes incorporate language that addresses the public notice rule provisions for NNSR, which removes the mandatory requirements to provide public notice in a newspaper and instead allows for electronic notice (``e- notice'') as an alternate noticing option for the State. EPA is proposing to approve these revisions pursuant to the Clean Air Act (CAA or Act) and implementing Federal regulations.

The Environmental Protection Agency (EPA or the Agency) is amending the requirements in Subpart J of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP) that govern the use of dispersants, other chemicals and other spill mitigating substances when responding to oil discharges into waters of the United States. Specifically, this action establishes monitoring requirements for dispersant use in response to major oil discharges and/or certain dispersant use situations in the navigable waters of the United States and adjoining shorelines, the waters of the contiguous zone, and the high seas beyond the contiguous zone in connection with activities under the Outer Continental Shelf Lands Act, activities under the Deepwater Port Act of 1974, or activities that may affect natural resources belonging to, appertaining to, or under the exclusive management authority of the United States, including resources under the Magnuson Fishery Conservation and Management Act of 1976 (``navigable waters of the United States and adjoining shorelines''). These new monitoring requirements are anticipated to better target dispersant use, thus reducing the risks to the environment. Further, the amendments are intended to ensure that On-Scene Coordinators (OSCs) and Regional Response Teams (RRTs) have relevant information to support response decision-making regarding dispersant use.

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) submission from the State of Oklahoma for the 2015 Ozone National Ambient Air Quality Standard (NAAQS), and proposing to disapprove elements of two SIP submissions for the 2010 sulfur dioxide (SO<INF>2</INF>) and the 2012 fine particulate matter (PM<INF>2.5</INF>) NAAQS. These infrastructure SIP (i-SIP) submissions address how the existing SIP provides for implementation, maintenance, and enforcement of these NAAQS. The i-SIP requirements are to ensure that the Oklahoma SIP is adequate to meet the state's responsibilities under the CAA for these NAAQS. Specifically, this proposed rule addresses the interstate visibility transport requirements of the i-SIP for the 2010 SO<INF>2</INF>, 2012 PM<INF>2.5</INF>, and 2015 Ozone NAAQS under CAA section 110(a)(2)(D)(i)(II). We are also proposing to find that the deficiencies in the Oklahoma SIP that form the basis of our proposed disapproval of the interstate visibility transport portions of the Oklahoma i-SIP submissions for the 2010 SO<INF>2</INF> and 2012 PM<INF>2.5</INF> NAAQS are remedied by the existing Federal Implementation Plan (FIP) in place for the Oklahoma Regional Haze program, and that no further federal action is required to address the proposed disapproval.

The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) revision submitted by Wisconsin on March 29, 2021, which amends a SIP submission previously submitted to EPA on January 22, 2016 and supplemented on July 18, 2016, and November 29, 2016, for attaining the 1-hour sulfur dioxide (SO<INF>2</INF>) primary national ambient air quality standard (NAAQS) for the Rhinelander SO<INF>2</INF> nonattainment area. This plan (herein referred to as Wisconsin's Rhinelander SO<INF>2</INF> plan or plan) includes Wisconsin's attainment demonstration and other elements required under the Clean Air Act (CAA). In addition to an attainment demonstration, the plan addresses the requirement for meeting reasonable further progress (RFP) toward attainment of the NAAQS, reasonably available control measures and reasonably available control technology (RACM/RACT), and contingency measures. This action supplements a prior action which found that Wisconsin had satisfied emission inventory and new source review (NSR) requirements for this area, but had not met requirements for the elements proposed to be approved here. EPA is proposing to conclude that Wisconsin has appropriately demonstrated that the plan provisions provide for attainment of the 2010 1-hour primary SO<INF>2</INF> NAAQS in the Rhinelander SO<INF>2</INF> nonattainment area and that the plan meets the other applicable requirements under the CAA.

The Environmental Protection Agency (EPA) is proposing to approve in part and disapprove in part portions of a state implementation plan (SIP) revision submitted by the State of California to meet Clean Air Act (CAA or ``Act'') requirements for the 1997 annual fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or ``standards'') in the San Joaquin Valley PM<INF>2.5</INF> nonattainment area. Specifically, the EPA is proposing to approve the 2013 base year emissions inventories in the submitted SIP revisions. Because the area did not attain by the State's projected attainment date of December 31, 2020, the EPA is proposing to disapprove the attainment demonstration and related elements, including the comprehensive precursor demonstration, five percent annual emission reductions demonstration, best available control measures (BACM) demonstration, reasonable further progress (RFP) demonstration, quantitative milestone demonstration, and contingency measures. The EPA is also proposing to disapprove the motor vehicle emission budgets in the plan as not meeting the requirements of the CAA and EPA regulations.

The North Dakota state plans establish performance standards and operating requirements for existing MSW landfills, CISWI units and ACI units within the State of North Dakota and provide for the implementation and enforcement of those standards and requirements by the Department. Finally, the EPA is also approving withdrawal of the North Dakota CAA section 111(d)/129 state plan for the control of air pollutants from existing hospital/ medical/infectious waste incineration (HMIWI) units. The EPA is approving this plan withdrawal following North Dakota's May 8, 2019 submittal of a negative declaration of existing HMIWI units in the State of North Dakota, and will be promulgating the State's negative declaration in lieu of a CAA section 111(d)/129 state plan for HMIWI units. The EPA is taking these actions pursuant to requirements of the CAA.

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the New York State Department of Environmental Conservation (NYSDEC). The SIP revision consists of the following: 2011 calendar year ozone precursor emission inventory for volatile organic compounds (VOCs), oxides of nitrogen (NO<INF>X</INF>), and carbon monoxide (CO) for the New York portion of the New York-Northern New Jersey-Long Island, Connecticut NY-NJ-CT area (New York Metropolitan Area, or NYMA) classified as serious ozone nonattainment for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS or standard), and the Jamestown (Chautauqua County) ozone nonattainment area classified as marginal for the 2008 8-hour ozone standard. In addition, the SIP revision also consists of the 2011 calendar year statewide periodic emissions inventory for volatile organic compounds, oxides of nitrogen, and carbon monoxide. Emission inventories are needed to develop and assess new control strategies that the states may use in attainment demonstration SIPs for the new National Ambient Air Quality Standards for ozone and PM<INF>2.5</INF>. The inventories may also serve as part of statewide inventories for purposes of regional modeling in ozone and play an important role in modeling demonstrations for areas classified as nonattainment for ozone and carbon monoxide. This action is being taken in accordance with the Clean Air Act (CAA).

In the Rules and Regulations section of this Federal Register, the Environmental Protection Agency (EPA) is granting a request by the California Air Resources Board (CARB or ``State'') to voluntarily reclassify the Eastern Kern nonattainment area (``Eastern Kern'') from ``Serious'' to ``Severe'' for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS) under section 181(b)(3) of the Clean Air Act (CAA). In this action, the EPA is proposing a schedule for the State to submit revisions to the state implementation plan (SIP) addressing Severe area requirements and to submit revisions to the title V operating permit rules for this area. Under the EPA's proposed schedule, California would be required to submit SIP revisions addressing Severe area requirements for Eastern Kern, including revisions to New Source Review (NSR) rules, no later than 18 months from the effective date of the EPA's final rule reclassifying Eastern Kern to Severe. Submittal of any corresponding revisions to the title V rules that apply in Eastern Kern would be due within six months of the effective date of the reclassification. Lastly, the EPA is proposing a deadline for implementation of new Reasonably Available Control Technology (RACT) rules as expeditiously as practicable but no later than 18 months from the date when the Severe area RACT SIP will be due.

The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) submitted by the State of Nebraska on July 16, 2020. This proposed action will amend the SIP to revise title 129 of the Nebraska Administrative Code by removing a portion of the SIP that addresses general conformity. General Conformity ensures that the actions taken by federal agencies do not interfere with a state's plan to attain and maintain national standards for air quality. Since states are no longer required to include general conformity requirements in SIPs, these proposed revisions remove unnecessary language and do not substantively change any existing statutory or regulatory requirement. The proposed revisions do not impact the stringency of the SIP or air quality nor do they impact the State's ability to attain or maintain the National Ambient Air Quality Standards. The EPA's proposed approval of this rule revision is in accordance with the requirements of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing to determine that the Hayden lead (Pb) nonattainment area (NAA) failed to attain the 2008 Pb primary and secondary national ambient air quality standards (NAAQS or ``standards'') by the applicable attainment date of October 3, 2019. This proposed determination is based upon monitored air quality data from November 2015-December 2018 for the 2008 Pb NAAQS. The EPA is also proposing to determine that the Hayden and Miami sulfur dioxide (SO<INF>2</INF>) NAAs failed to attain the 2010 1-hour SO<INF>2</INF> primary NAAQS by the applicable attainment date of October 4, 2018, based upon monitored air quality data from January 2015-December 2017. If the EPA finalizes these determinations as proposed, the State of Arizona will be required to submit revisions to the Arizona State Implementation Plan (SIP) that, among other elements, provide for expeditious attainment of the 2008 Pb and 2010 SO<INF>2</INF> standards.

The Environmental Protection Agency (EPA) is correcting the erroneous incorporation of the asbestos National Emission Standards for Hazardous Air Pollutants (NESHAP) requirements into the Jefferson County portion of the Kentucky State Implementation Plan (SIP). The continued presence of the asbestos requirements in the Jefferson County portion of the Kentucky SIP is inappropriate and potentially confusing and thus problematic for affected sources, the Commonwealth, local agencies, and EPA. EPA is removing the asbestos requirements because these requirements are not related to the attainment and maintenance of the national ambient air quality standards (NAAQS) and are therefore unrelated to the Clean Air Act (CAA or Act) requirements for SIPs.

The Environmental Protection Agency (EPA) is reconsidering a prior action that withdrew a waiver of preemption for California's zero emission vehicle (ZEV) mandate and greenhouse gas (GHG) emission standards within California's Advanced Clean Car (ACC) program for purposes of rescinding that action. The ACC program waiver, as it pertains to the GHG emission standards and ZEV mandates, will become effective should EPA rescind the prior action. On September 27, 2019, EPA and the National Highway Transportation Safety Administration (NHTSA) issued an action titled ``The Safer Affordable Fuel-Efficient Vehicles Rule Part One: One National Program'' (SAFE 1) that included, among other matters, EPA's determination that the Agency had authority to reconsider the ACC program waiver and that elements of the ACC program waiver should be withdrawn due to NHTSA's action under the Energy Policy & Conservation Act (EPCA) and Clean Air Act (CAA) preemption provisions. In addition, SAFE 1 included EPA's interpretation of whether States can adopt California's GHG emission standards under section 177 of the CAA. EPA believes that there are significant issues regarding whether SAFE 1 was a valid and appropriate exercise of agency authority, including the amount of time that had passed since EPA's 2013 waiver decision, the novel approach and legal interpretations used in SAFE 1, and whether EPA took proper account of the environmental conditions in California and the environmental consequences from the waiver withdrawal in SAFE 1. Further, EPA will be addressing issues raised in several petitions for reconsideration of SAFE 1, including one filed by California (jointly with a number of States and Cities) and one jointly filed by nongovernmental organizations. Finally, on January 20, 2021, President Biden issued an Executive Order on ``Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis.'' The President directed the Federal Agencies to ``immediately review'' SAFE 1, and to consider action ``suspending, revising, or rescinding'' that action by April 2021. Therefore, based upon the issues associated with SAFE 1, the petitions for reconsideration, and the Executive Order, this Federal Register notice initiates reconsideration of SAFE 1 and announces a virtual public hearing as well as an opportunity to submit new written comment.

Through this supplemental notice of proposed rulemaking (``supplemental proposal'' or ``SNPRM''), the Environmental Protection Agency (EPA) is seeking public comment on the Agency's additional and clarified technical rationale related to the proposed approval of Tennessee's February 26, 2020, state implementation plan (SIP) revisions requesting the removal of Tennessee's motor vehicle inspection and maintenance (I/M) program requirements for Davidson, Sumner, Rutherford, Williamson, and Wilson Counties in Tennessee (also known as the Middle Tennessee Area) and Hamilton County (also known as the Chattanooga Area), from the federally-approved SIP. Specifically, EPA proposes to affirm that the Hamilton County and Middle Tennessee areas would continue to attain and maintain the national ambient air quality standards (NAAQS or standards) after removal of the I/M program, and to rely on an emissions inventory comparison to inform its determination that both areas would continue to attain and maintain the ozone and carbon monoxide (CO) NAAQS. EPA is further proposing to conclude that the removal of the I/M program will not interfere with other states' ability to attain and maintain the 2008 ozone NAAQS under the good neighbor provision of the Clean Air Act (CAA or Act) and providing additional information related to that conclusion. EPA is now taking comment on the use of this comparison and additional information in this supplemental proposal.

Pursuant to the Federal Clean Air Act (CAA or the ``Act''), the Environmental Protection Agency (EPA or the ``Agency'') is proposing approval of a CAA section 111(d) plan submitted by the North Dakota Department of Environmental Quality (NDDEQ or the ``Department'') on July 28, 2020 to regulate landfill gas and its components from existing municipal solid waste (MSW) landfills. The EPA is also proposing approval of a CAA section 111(d)/129 plan submitted by the Department on the same date to regulate air pollutants from existing commercial and industrial solid waste incineration (CISWI) units and air curtain incinerators (ACI). These plans provide for the State's implementation and enforcement of the federal emission guidelines (EG) for existing MSW landfills, CISWI units and ACI in North Dakota. The EPA with this proposed rule is also notifying the public that the Agency has received a request from the State of North Dakota, dated May 8, 2019, for withdrawal of a previously approved CAA section 111(d)/129 plan for hospital/medical/infectious waste incineration (HMIWI) units and for Agency approval of a negative declaration of such units within the State. Approval of this negative declaration will stand in lieu of a North Dakota CAA section 111(d)/129 plan for HMIWI units.

The Environmental Protection Agency (EPA) is making an interim final determination that the Arizona Department of Environmental Quality (ADEQ) has submitted rules and other materials on behalf of the Pinal County Air Quality Control District (PCAQCD or District) that correct deficiencies in its Clean Air Act (CAA or Act) state implementation plan (SIP) provisions concerning ozone nonattainment requirements. This determination is based on a proposed approval, published elsewhere in this Federal Register, of PCAQCD's reasonably available control technology (RACT) SIP rules and negative declarations. The effect of this interim final determination is that the imposition of sanctions that were triggered by a previous partial disapproval and limited disapproval by the EPA in 2019 is now deferred. If the EPA finalizes its approval of PCAQCD's submission, relief from these sanctions will become permanent.

The Environmental Protection Agency (EPA) is proposing to correct the erroneous incorporation of asbestos National Emission Standards for Hazardous Air Pollutants (NESHAP) requirements into the Jefferson County portion of the Kentucky State Implementation Plan (SIP). The continued presence of the asbestos requirements in the Jefferson County portion of the Kentucky SIP is inappropriate and potentially confusing and thus problematic for affected sources, the Commonwealth, local agencies, and EPA. EPA is proposing to remove the asbestos requirements because these requirements are not related to the attainment and maintenance of the national ambient air quality standards (NAAQS) and are therefore unrelated to the Clean Air Act (CAA or ``Act'') requirements for SIPs.

The Environmental Protection Agency (EPA) is proposing to approve a revision to New York's section 111(d) state plan (the ``State Plan'') for Municipal Solid Waste (MSW) landfills, pursuant to the Clean Air Act (``CAA'' or the ``Act''). The proposed State Plan revision consists of amendments to New York's ``Landfill Gas Collection and Control Systems for Certain Municipal Solid Waste Landfills,'' as well as attendant revisions to ``General Provisions.'' The primary goal of this regulation is to implement and enforce the Emission Guidelines (EG) promulgated by the EPA for MSW landfills on August 29, 2016. The goal of the revised federal EG is to reduce emissions of landfill gas containing Non-methane Organic Compounds (NMOC) and methane by lowering the emissions threshold at which an existing MSW landfill must install and operate a Gas Collection and Control System (GCCS). The emission threshold reduction will address air emissions from all affected MSW landfills, including NMOC and methane. The reduction of emissions will improve air quality and protect the public health from exposure to landfill gas emissions.

With this direct final rule, the Environmental Protection Agency (EPA or the ``Agency'') is promulgating full approval of the revised and recodified North Dakota operating permit program for stationary sources subject to title V of the Clean Air Act (CAA or the ``Act''). On August 6, 2018, North Dakota submitted a request for approval of its revisions to the North Dakota operating permit program (the ``title V program'') for stationary sources subject to title V of the CAA and recodification of the State's title V program under a new title of the North Dakota Administrative Code (NDAC). The EPA determined that the revised and recodified program substantially met the requirements of title V of the Act and Code of Federal Regulations (CFR) but was not fully approvable because the State law provisions for judicial review were not consistent with program requirements found in the CFR. Thus, EPA issued an interim approval of North Dakota's title V program. North Dakota has made the changes required for full program approval. Accordingly, the EPA is taking this action in accordance with the CAA and CFR title V program approval requirements. This is a direct final action because the action is deemed noncontroversial and we do not expect adverse comments.

Description: 

On October 22, 2012, the EPA published a final rule in the Federal Register promulgating a Federal Implementation Plan (FIP) intended to address regional haze obligations for the Territory of the United States Virgin Islands. However, at that time EPA erroneously failed to incorporate into the Code of Federal Regulations (CFR) certain emission limits that had been determined to be necessary to satisfy those obligations and that had been proposed and included in the docket for the action. EPA is proposing to correct this inadvertent error by incorporating the previously noticed limits into the CFR. EPA is not reopening any of its previous determinations here.

Whenever the Environmental Protection Agency (EPA) promulgates a new or revised National Ambient Air Quality Standard (NAAQS), the Clean Air Act requires each state to make a State Implementation Plan (SIP) submission to establish that its SIP provides for the implementation, maintenance, and enforcement of the revised NAAQS. This type of SIP submission is commonly referred to as an infrastructure SIP submission. The EPA is approving the State of Washington's September 30, 2019 and April 3, 2020, SIP submissions as meeting specific infrastructure requirements for the 2010 sulfur dioxide and 2015 ozone NAAQS.
