Learn More🌍Congressional Review Act Revocation of Waste Emissions Charge
Congress has passed and the President has signed a joint resolution of disapproval under the Congressional Review Act (CRA) of the Environmental Protection Agency's (EPA) final rule titled, "Waste Emissions Charge for Petroleum and Natural Gas Systems: Procedures for Facilitating Compliance, Including Netting and Exemptions" (2024 WEC Final Rule). The 2024 WEC Final Rule implemented and facilitated compliance with the requirements of the Waste Emissions Charge in the Clean Air Act's (CAA) Methane Emissions Reduction Program. Under the joint resolution and by operation of the CRA, the 2024 WEC Final Rule now has no legal force or effect. Because the rule has been nullified, the EPA is removing it from the Code of Federal Regulations (CFR). This action is exempt from notice-and-comment rulemaking because it is ministerial in nature.

This regulation establishes an exemption from the requirement of a tolerance for residues of l-arginine (CAS Reg. No. 74-79-3) when used as an inert ingredient (protein stabilizer) on greenhouse pre- bloom cucumbers at a maximum concentration of <=1%. D. O'Shaughnessy Consulting, Inc. on behalf of A&L Biological Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of l-arginine, when used in accordance with the terms of those exemptions.
Learn More🌫️South Dakota's Regional Haze Plan Approval and Business Impact
The Environmental Protection Agency (EPA) is proposing to approve the regional haze state implementation plan (SIP) submission submitted by the State of South Dakota on July 29, 2022 (South Dakota's 2022 SIP submission), under the Clean Air Act (CAA) and the EPA's Regional Haze Rule (RHR) for the program's second implementation period. South Dakota's 2022 SIP submission addresses the requirement that states revise their long-term strategies every implementation period to make reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. South Dakota's 2022 SIP submission also addresses other applicable requirements for the second implementation period of the regional haze program. The EPA is taking this action pursuant to the CAA.
Learn More🌬️EPA Approves Washington State SIP Revisions for Clean Air Compliance
The Environmental Protection Agency (EPA) is approving Washington State Implementation Plan (SIP) revisions to the Southwest Clean Air Agency (SWCAA) air quality regulations submitted by the State of Washington, through the Department of Ecology (Ecology) on June 22, 2023. The revisions were submitted in part to respond to the EPA's June 12, 2015 "SIP call" in which the EPA found a provision in the Washington SIP applicable in the area regulated by SWCAA to be substantially inadequate, providing affirmative defenses that operate to limit the jurisdiction of the Federal court in an enforcement action related to excess emissions during startup, shutdown, and malfunction (SSM) events. The EPA's approval of the SIP revisions to the substantially inadequate provision corrects the SWCAA deficiency identified in the 2015 SSM SIP call and the EPA's January 2022 finding of failure to submit. Washington withdrew some portions of the revisions submitted that were not identified in the 2015 SSM SIP call and therefore the EPA is not approving those withdrawn portions. The EPA proposed to approve this action on December 10, 2024, and received no comments.

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM) on December 20, 2023.

The revision also addresses typographical errors and increases clarity and consistency with EPA's definitions and Alabama's Legislative Services Agency requirements.
Learn More🌬️Proposed Rule for Emissions Control in Missouri Petroleum Sector
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Missouri State Implementation Plan (SIP) related to the control of emissions during petroleum liquid storage, loading and transfer in the Kansas City metropolitan area. The revisions to this rule include adding incorporations by reference to other state rules, adding definitions specific to the rule, revising unnecessarily restrictive or duplicative language, and making administrative wording changes. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's proposed approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
Learn More🌬️Colorado Air Quality Plan Approval for Ozone Standards
The Environmental Protection Agency (EPA) is proposing to approve state implementation plan (SIP) submittals under the Clean Air Act (CAA) that address contingency measures requirements for the 2008 ozone National Ambient Air Quality Standards (NAAQS) for the Denver Metro/North Front Range (DMNFR) ozone nonattainment area. The requirements at issue relate to the area's previous Serious nonattainment classification. The EPA is proposing to find that the State has met the applicable CAA requirements for Serious area contingency measures and is proposing approval of the contingency measures SIP submittals, except that we are not taking action on one of the two identified contingency measures included in the submittals.
