Public Hearing for Vehicle Test Procedure Adjustments for Tier 3 Certification Test Fuel
The Environmental Protection Agency (EPA) is announcing a virtual public hearing to be held July 13, 2020, on its proposed Vehicle Test Procedure Adjustments for Tier 3 Certification Test Fuel rule, which was published on May 13, 2020. EPA is proposing adjustment factors to apply to vehicle GHG and fuel economy test results for the GHG and CAFE programs and the Fuel Economy and Environment Label as EPA separately implements changes in light-duty vehicle gasoline test fuel properties.
Approval and Promulgation of Implementation Plans; Designation of Areas for Air Quality Planning Purposes; California; South Coast Moderate Area Plan and Reclassification as Serious Nonattainment for the 2012 PM2.5
The Environmental Protection Agency (EPA) is proposing to approve or conditionally approve portions of a state implementation plan (SIP) revision submitted by California to address Clean Air Act (CAA or ``Act'') requirements for the 2006 and 2012 fine particulate matter (PM2.5) national ambient air quality standards (NAAQS or ``standards'') in the Los Angeles-South Coast Air Basin (``South Coast'') PM2.5 nonattainment area. Specifically, the EPA is proposing to approve all but the contingency measure element of the submitted SIP revision as meeting all applicable Moderate area requirements for the 2012 annual PM2.5 NAAQS, and to conditionally approve the contingency measure element as meeting both the Moderate area contingency measure requirement for the 2012 annual PM2.5 NAAQS and the Serious area contingency measure requirement for the 2006 24-hour PM2.5 NAAQS. In addition, the EPA is proposing to approve 2019 and 2022 motor vehicle emissions budgets for use in transportation conformity analyses for the 2012 annual PM2.5 NAAQS. The EPA is also proposing to reclassify the South Coast PM2.5 nonattainment area, including reservation areas of Indian country and any other area of Indian country within it where the EPA or a tribe has demonstrated that the tribe has jurisdiction, as a Serious nonattainment area for the 2012 annual PM2.5 NAAQS based on the EPA's determination that the area cannot practicably attain the standard by the applicable Moderate area attainment date of December 31, 2021. Upon final reclassification of the South Coast as a Serious area for this NAAQS, California will be required to submit a Serious area plan for the area that includes a demonstration of attainment by the applicable Serious area attainment date, which is no later than December 31, 2025, or by the most expeditious alternative date practicable, in accordance with the requirements of part D of title I of the CAA.
National Emission Standards for Hazardous Air Pollutants: Cellulose Products Manufacturing Residual Risk and Technology Review
This action finalizes the residual risk and technology review (RTR) conducted for the Miscellaneous Viscose Processes and Cellulose Ether Production source categories regulated under the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Cellulose Products Manufacturing. The EPA is finalizing the proposed determination that the risks from both source categories are acceptable and that the current NESHAP provides an ample margin of safety to protect public health. The EPA identified no new cost-effective controls under the technology review to achieve further emissions reductions. These final amendments address emissions during startup, shutdown, and malfunction (SSM) events; add electronic reporting requirements; add provisions for periodic emissions performance testing for facilities using non-recovery control devices; add a provision allowing more flexibility for monitoring of biofilter control devices; and make technical and editorial changes. Although these amendments are not expected to reduce emissions of hazardous air pollutants (HAP), they will improve monitoring, compliance, and implementation of the rule.
