Approval and Promulgation of Air Quality Implementation Plans; District of Columbia; Emissions Statement Certification for the 2015 Ozone National Ambient Air Quality Standard
The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision formally submitted by the District of Columbia Department of Energy and the Environment (DOEE). Under the Clean Air Act (CAA), a state's SIP must include an emission statement regulation that requires stationary sources in ozone nonattainment areas classified as marginal or above to report annual emissions of nitrogen oxides (NOX) and volatile organic compounds (VOC). This SIP revision provides the District's certification that its existing emissions statement program satisfies the emissions statement requirements of the CAA for the 2015 ozone National Ambient Air Quality Standard (NAAQS). EPA is proposing to approve the District's emissions statement program certification for the 2015 ozone NAAQS as a SIP revision in accordance with the requirements of the CAA.
Availability of the Systematic Review Protocol for the Inorganic Mercury Salts Integrated Risk Information System (IRIS) Assessment
The Environmental Protection Agency (EPA) is announcing a 30- day public comment period associated with release of the Systematic Review Protocol for the Inorganic Mercury Salts IRIS Assessment. This document communicates the rationale for conducting the assessment of inorganic mercury salts, describes screening criteria to identify relevant literature, outlines the approach for evaluating study quality, and describes the methods for dose-response analysis.
Air Plan Approval; KY; Jefferson County; Gasoline Loading Facilities at Existing Bulk Terminals and New Bulk Plants
The Environmental Protection Agency (EPA) is approving revisions to the Jefferson County portion of the Kentucky State Implementation Plan (SIP), submitted by the Commonwealth of Kentucky, through the Energy and Environment Cabinet (Cabinet) on September 5, 2019. The revisions were submitted by the Cabinet on behalf of the Louisville Metro Air Pollution Control District (District) and include amendments related to the standards for existing gasoline loading facilities at bulk terminals and new gasoline loading facilities at bulk plants. The amendments to these standards replace a requirement for gasoline tank trucks to possess a valid Kentucky pressure vacuum test sticker with a requirement for specific vapor tightness testing and recordkeeping procedures, clarify rule applicability, and remove language stating that a pressure measuring device will be supplied by the District. EPA is approving the revisions because they are consistent with the Clean Air Act (CAA or Act).
Public Water System Supervision Program Revision for the State of Colorado
Public notice is hereby given that the state of Colorado has revised its Public Water System Supervision (PWSS) Program by adopting federal regulations for the Revised Total Coliform Rule (RTCR) that correspond to the National Primary Drinking Water Regulations (NPDWR). EPA has reviewed Colorado's regulations and determined they are no less stringent than the federal regulations. EPA is proposing to approve the RTCR for Colorado. This approval action does not extend to public water systems in Indian country. Please see SUPPLEMENTARY INFORMATION, Unit B.
Air Plan Approval; California; South Coast Air Quality Management District; Ventura County Air Pollution Control District; Correction
The Environmental Protection Agency (EPA) is correcting a final rule that appeared in the Federal Register on February 24, 2021. That rule approved South Coast Air Quality Management District Rule 1168 and Ventura County Air Pollution Control District Rule 74.20 as revisions to the California State Implementation Plan (SIP).
Court Vacatur of Exemption From Emission Standards During Periods of Startup, Shutdown, and Malfunction
The U.S. Environmental Protection Agency (EPA) is amending the Code of Federal Regulations (CFR) to reflect a court order regarding the General Provisions for National Emissions Standards for Hazardous Air Pollutants (NESHAP) issued on December 19, 2008, by the United States Court of Appeals for the District of Columbia Circuit (the court). The court vacated two provisions in the General Provisions that exempted sources from hazardous air pollutant (HAP) non-opacity and opacity emission standards during periods of startup, shutdown, and malfunction (SSM). The court held that under the Clean Air Act (CAA), emissions standards or limitations must be continuous in nature and that the SSM exemptions in these two provisions violate this requirement. This ministerial action revises these two NESHAP General Provisions in the CFR to conform to the court's order.
Revisions to the Unregulated Contaminant Monitoring Rule (UCMR 5) for Public Water Systems and Announcement of Public Meeting
The U.S. Environmental Protection Agency (EPA or Agency) is proposing a Safe Drinking Water Act (SDWA) rule that would require public water systems to collect national occurrence data for 29 per- and polyfluoroalkyl substances (PFAS) and lithium. This proposed rule would require all community and non-transient non community water systems serving 3,300 or more people, and a representative sample of smaller water systems, to conduct monitoring. PFAS and lithium are not currently subject to national primary drinking water regulations, and EPA is proposing to require the collection of drinking water occurrence data to inform EPA decisions. This proposal fulfills a key commitment in ``EPA's 2019 Per- and Polyfluoroalkyl Substances (PFAS) Action Plan'' (https://www.epa.gov/pfas/epas-pfas-action-plan) by proposing the collection of more drinking water occurrence data for a broader group of PFAS. EPA is also announcing two public meetings (via webinar) to discuss this proposal of the fifth Unregulated Contaminant Monitoring Rule (UCMR 5).
