The Environmental Protection Agency (EPA) has approved a revision to Delaware's state implementation plan (SIP) concerning air quality standards. This update aligns Delaware's rules with the current National Ambient Air Quality Standards (NAAQS) by revising standards for ground-level ozone and removing outdated sulfur dioxide standards that were revoked by the EPA. The amendments also update references for EPA's sampling and analytical procedures. This final rule takes effect on January 22, 2025, expanding the federal enforceability of these standards.
Simple Explanation
The EPA has decided that Delaware can change its rules about air pollution to match new standards, like updating rules for cleaner air and removing old ones they don't need anymore. These changes will officially start on January 22, 2025, to help ensure everyone can enjoy cleaner, healthier air.
