The Environmental Protection Agency (EPA) is proposing a new rule to approve changes to air quality regulations in California's Mojave Desert. These changes focus on reducing emissions of nitrogen oxides (NOX) from industrial equipment like boilers and heaters, which contribute to air pollution problems like smog and ozone. The updated rule, MDAQMD Rule 1157, sets stricter limits on these emissions and removes certain exemptions to align with federal standards. Public comments on this proposal are invited until January 27, 2025, and if approved, the rule will be added to the enforceable state implementation plan.

The Environmental Protection Agency (EPA) is making an interim decision to delay certain penalties for the Mojave Desert Air Quality Management District (MDAQMD) in California. The delay is because the MDAQMD has updated Rule 1157 to fix issues related to controlling nitrogen oxide emissions. This decision means relief from penalties, initially triggered by EPA's limited disapproval in 2023, may become permanent if the amendments are fully approved following public comments. The EPA is allowing the public to comment on this decision until January 27, 2025.

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 approved revisions to the Mojave Desert Air Quality Management District's (MDAQMD) portion of the California State Implementation Plan (SIP). These revisions involve updating rules for managing air pollutants such as volatile organic compounds, nitrogen oxides, and particulate matter. The changes aim to ensure that the SIP reflects current rules that align with those enforced by the MDAQMD. The final rules will become effective on January 3, 2025, and include the incorporation of certain administrative and prohibitory standards into the SIP.
