Bill > HB291

This bill modifies Montana's Clean Air Act to limit the Department of Environmental Quality (DEQ) and local air pollution control programs from establishing air quality standards that are more stringent than federal regulations. Specifically, the bill restricts the department's ability to set emission limits that exceed federal standards, with some exceptions for existing requirements and areas classified as non-attainment. The bill requires that any proposed more stringent standards must go through a detailed public hearing and comment process, with written findings demonstrating the need for stricter regulations. For local air pollution control programs, the bill imposes similar restrictions, preventing them from adopting rules more stringent than state or federal guidelines without meeting specific procedural requirements. The bill also limits the DEQ's ability to delegate air pollution control authority for large emission sources or complex facilities. Additionally, the bill mandates more transparent rulemaking processes for local air pollution control programs, including providing detailed public notices, maintaining lists of interested persons, and creating written responses to public comments. The legislation will take effect immediately upon passage and approval, reflecting a significant constraint on environmental regulatory discretion in Montana.
