The Environmental Protection Agency (EPA) has finalized a Federal Implementation Plan (FIP) under the Clean Air Act for the Mojave Desert Air Quality Management District in California. This new rule includes stricter guidelines for New Source Review (NSR) in nonattainment areas where air quality standards are not met. The FIP aims to regulate the construction of new major sources and modifications of existing sources, addressing deficiencies in the existing Mojave Desert program. An important aspect of this rule is the EPA's disapproval of a Mojave Desert District rule regarding emissions offsets, following a court decision questioning the EPA's previous approval of that rule.

The Environmental Protection Agency (EPA) has finalized a rule to update the Federal Implementation Plan (FIP) for sulfur dioxide emissions from four sources in Billings and Laurel, Montana. This rule removes the previous allowance for exceeding emission limits during malfunctions, startups, and shutdowns, as it did not align with the Clean Air Act. The EPA conducted an environmental justice analysis and found no significant disparities in pollution burden around the affected facilities. This rule will take effect on February 18, 2025, and is intended to have a neutral to positive impact on local air quality.

The Environmental Protection Agency (EPA) issued a final rule that partially approves and partially disapproves Arizona's State Implementation Plan (SIP) for addressing regional haze, a form of air pollution. Arizona's plan aimed to tackle haze by revising strategies to improve visibility in protected natural areas. The EPA found that while some parts of the plan meet federal requirements, others do not because they lack adequate analysis or justification. The EPA's decision starts a process that could lead to federal intervention unless Arizona submits an improved plan that meets all necessary criteria.
