Ortho-Phthalaldehyde; Receipt of Application for Emergency Exemption, Solicitation of Public Comment
EPA has received a specific exemption request from the National Aeronautics and Space Administration (NASA) to use the pesticide ortho-phthalaldehyde (OPA, CAS No. 643-79-8) to treat the coolant fluid of the internal active thermal control system of the International Space Station to control aerobic/microaerophilic bacteria in the aqueous coolant. The applicant proposes the use of a new chemical which has not been registered by EPA. Therefore, in accordance with the Code of Federal Regulations, EPA is soliciting public comment before making the decision whether or not to grant the exemption.
Air Plan Approval; Rhode Island; 2015 Ozone NAAQS Interstate Transport Requirements
The Clean Air Act (CAA) requires each State Implementation Plan (SIP) to contain adequate provisions prohibiting emissions that will have certain adverse air quality effects in other states. The State of Rhode Island made a submission to the Environmental Protection Agency (EPA) to address these requirements for the 2015 ozone National Ambient Air Quality Standards (NAAQS). EPA is proposing to approve the submission for Rhode Island as meeting the requirement that each SIP contain adequate provisions to prohibit emissions that will significantly contribute to nonattainment or interfere with maintenance of the 2015 ozone NAAQS in any other state.

The CHPAC advises the Environmental Protection Agency (EPA) on science, regulations and other issues relating to children's environmental health.
Air Plan Partial Disapproval; Commonwealth of Pennsylvania; Reasonably Available Control Technology Regulations for the 1997 and 2008 Ozone National Ambient Air Quality Standards
As a result of the Third Circuit Court of Appeals' decision, dated August 27, 2020, in Sierra Club v. U.S. EPA, No. 19-2562 (3rd Cir. 2020), the Environmental Protection Agency (EPA) is proposing to partially disapprove a specific part of a state implementation plan (SIP) revision that had been previously approved by EPA. On May 19, 2019, EPA fully approved certain parts of a SIP revision submitted by the Commonwealth of Pennsylvania to address reasonably available control technology (RACT) for the 1997 and 2008 ozone national ambient air quality standards (NAAQS), and conditionally approved other parts of that submission. The court vacated EPA's approval of a portion of the SIP revision, as discussed below, and ordered that EPA either approve a new SIP revision addressing the court's decision or promulgate a federal implementation plan (FIP) within two years. EPA is therefore proposing to disapprove the portion of the SIP submission addressed by the court's decision. This action is being taken under the Clean Air Act (CAA).
Air Plan Approval; ID; West Silver Valley Redesignation to Attainment for the 2012 Annual PM2.5
The Environmental Protection Agency (EPA) is proposing to redesignate the West Silver Valley, Idaho nonattainment area to attainment for the 2012 annual fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS). EPA is also proposing to approve a maintenance plan for the area demonstrating continued compliance with the NAAQS through 2031, which the Idaho Department of Environmental Quality (IDEQ) submitted along with the redesignation request on June 2, 2020, for inclusion into the Idaho State Implementation Plan (SIP). Additionally, EPA is proposing to approve the 2031 motor vehicle emissions budgets included in Idaho's maintenance plan for PM2.5, nitrogen oxides (NOX) and volatile organic compounds (VOCs). EPA is proposing this action pursuant to the Clean Air Act (CAA or the Act).
