The Environmental Protection Agency (EPA) is suggesting changes to California's state implementation plan (SIP) for handling carbon monoxide (CO) in three areas: Chico, Modesto, and Stockton. This proposal would remove certain CO contingency measures and monitoring needs, as past data shows CO levels have been consistently low and well within safe limits. The EPA is confident that these changes won't harm air quality standards since CO emissions have significantly decreased over the years. They are asking for public feedback on these changes by April 30, 2025.
Simple Explanation
The EPA wants to change the rules about checking the air for a harmful gas called carbon monoxide in three places in California because it's been safe for a long time. They are asking people what they think about this idea.
