Senate Bill No. 275, known as the Louisiana Community Air Monitoring Reliability Act, aims to establish state standards for community air monitoring programs operated by non-governmental entities. The bill outlines the purpose of these programs, which is to ensure that the data collected provides the public with accurate air quality information. It applies to entities that receive public or private funds for developing and maintaining these monitoring programs. The bill also includes definitions for key terms, such as "criteria air pollutants" and "hazardous air pollutants," and sets forth requirements for data collection and integrity.

The legislation mandates that community air monitoring programs adhere to science-based standards and utilize approved methods for monitoring air pollutants. It allows the Louisiana Department of Environmental Quality to take necessary actions if monitoring data indicates noncompliance with National Ambient Air Quality Standards (NAAQS), including identifying pollution sources and implementing control measures. Importantly, the bill prohibits the use of non-compliant monitoring data for enforcement actions, fines, or allegations of violations under various environmental laws. The act will take effect upon the governor's signature or after the designated time for gubernatorial action.
