A bill to amend the Toxic Substances Control Act to clarify the exemption for replacement parts. [Congressional Record 21 January 2026 [House] Pages H1170-H1172)

USFWS are removing the Southeast U.S. distinct population segment (DPS) of the wood stork (Mycteria americana) from the Federal List of Endangered and Threatened Wildlife. After a review of the best scientific and commercial data available, they find that delisting the species is warranted. Their review indicates that the threats to the Southeast U.S. DPS of the wood stork have been eliminated or reduced to the point that the species no longer meets the definition of an endangered species or threatened species under the ESA. Accordingly, the prohibitions and conservation measures provided by the Act, particularly through sections 4 and 7, will no longer apply to the Southeast U.S. DPS of the wood stork. This rule is effective 12 March 2026.

EPA is finalizing amendments to the new source performance standards (NSPS) for stationary combustion turbines and stationary gas turbines pursuant to a review required by the Clean Air Act (CAA). As a result of this review, the EPA is establishing subcategories for new, modified, or reconstructed stationary combustion turbines based on size, rates of utilization, design efficiency, and fuel type. The EPA determined that combustion controls are the best system of emission reduction (BSER) for nitrogen oxide (NOX) emissions for most new, modified, or reconstructed stationary combustion turbines. For one subcategory, the BSER for NOX is combustion controls with the addition of selective catalytic reduction (SCR). The EPA further determined that the BSER for sulfur dioxide (SO2) emissions has not changed since the last NSPS review. Based on these determinations, the Agency is promulgating standards of performance in a new subpart of the Code of Federal Regulations (CFR). The Agency is also adding a subcategory for stationary combustion turbines that are used in temporary applications, exempting certain sources from title V requirements, and finalizing other provisions. The EPA is finalizing amendments to existing regulations to address or clarify specific technical and editorial issues. This final rule is effective on 15 January 2026.
