Environmental Protection Agency June 27, 2019 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to approve State Implementation Plan (SIP) and Operating Permit Program revisions submitted by the State of South Dakota on October 23, 2015, related to South Dakota's Air Pollution Control Program. The October 23, 2015 submittal revises certain definitions in the Prevention of Significant Deterioration (PSD) permitting rules and general definition section related to greenhouse gases (GHGs). In this rulemaking, we are proposing action on portions of the October 23, 2015 submittal, which were not acted on in our previous final rulemaking published on October 13, 2016. The effect of this rulemaking is to ensure that certain definitions in South Dakota's PSD rules are in compliance with the federal PSD requirements. This action is being taken under the Clean Air Act (CAA).

The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Solvent Extraction for Vegetable Oil Production. The source category addressed in this action is the Solvent Extraction for Vegetable Oil Production source category. The EPA is proposing the results of the residual risk and technology review (RTR) that the EPA is required to conduct in accordance with the Clean Air Act (CAA). Based on the results of the EPA's risk review, the Agency is proposing that risk due to emissions of air toxics from this source category is acceptable and that the current NESHAP provides an ample margin of safety to protect public health. Under the technology review, the EPA is proposing there are no developments in practices, processes, or control technologies that necessitate revision of the standards. Therefore, the EPA is proposing no revisions to the numerical emission limits based on these analyses. However, the EPA is proposing to revise provisions pertaining to emissions during periods of startup, shutdown, and malfunction (SSM); add requirements for electronic reporting of certain notifications and reports and performance test results; and make other minor clarifications and corrections. Although the proposed amendments would not result in reductions in emissions of hazardous air pollutants (HAP), if finalized, they would result in improved compliance and implementation of the rule.
