    The Environmental Protection Agency (EPA) has officially approved the State of Washington's request to redesignate a part of Whatcom County from a "nonattainment" area to an "attainment" area for sulfur dioxide (SOâ‚‚) air quality standards. This redesignation follows the closure of the Intalco Aluminum LLC smelter, which previously caused high SOâ‚‚ levels. Alongside the redesignation, EPA has approved Washington's maintenance plan to ensure the area continues to meet air quality standards, which includes monitoring strategies for future potential pollution sources. This decision was finalized on December 11, 2024, and becomes effective on January 16, 2025.

    Simple Explanation

    The EPA said yes to Washington's request to fix air pollution by changing a part of Whatcom County to be healthy again after a dirty factory closed, and they'll keep checking the air to make sure it stays clean.

    The Environmental Protection Agency (EPA) is planning to approve Utah's request to redesignate the Logan, Utah-Idaho area to meet the air quality standards for PM2.5, a type of fine particulate matter.

The approval would involve updates to the Utah State Implementation Plan (SIP), which includes various local air quality control measures. The plan also outlines continued monitoring to ensure air quality is maintained and sets contingency measures if air quality standards are exceeded in the future.

    Simple Explanation

    The EPA wants to approve Utah's plan to clean up the air in a specific area, showing that it now meets safety standards for tiny, potentially harmful particles. This decision will change some local air rules and include checks to keep the air clean in the future.
