Modifies provisions relating to standards and guidelines established by the environmental conservation commission

HB 2361 modifies the authority of Missouri's environmental conservation commission regarding air quality standards and the regulation of residential wood-burning heaters. The bill ensures that state air rules meet federal Clean Air Act requirements without being stricter, while allowing the commission to grant exceptions for economic hardship or physical impossibility. It also restricts the regulation of existing wood-burning appliances installed before August 28, 2014, and requires legislative approval before new rules for these heaters can take effect. Additionally, the legislation outlines the composition, appointment terms, and meeting procedures for the commission, emphasizing public representation and specific expertise in water and air conservation.
