Reporting entities, as defined in proposed law, are excluded. Proposed law defines "criteria air pollutants" as those for which National Ambient Air Quality Standards (NAAQS) are established under the Clean Air Act, including ozone, particulates, carbon monoxide, lead, sulfur dioxide, and nitrogen dioxide. Proposed law defines "department" as the Louisiana Dept. of Environmental Quality (DEQ). Proposed law defines "EPA" as the U.S. Environmental Protection Agency.

Proposed law requires community air monitoring programs that seek allege violations or noncompliance with the Clean Air Act, Louisiana Environmental Quality Act or other rule or law to use the standards provided in federal law and current EPA-approved testing and monitoring methods. Proposed law requires that equipment, software, and methods for data collection and analysis use the current EPA-approved testing and monitoring methods. Requires that analysis be through a LELAP-approved laboratory or include quality assurance certification. Prohibits use of equipment or methods that are proprietary or not publicly available. Proposed law provides that DEQ may use data collected through programs to review compliance with NAAQS. Provides that DEQ may consider actions including source identification, pollution control measures, and public outreach and education. Requires such actions be in accordance with the Clean Air Act. Proposed law provides that DEQ may use data collected to review compliance with state ambient air quality standards for hazardous or toxic air pollutants. Provides that DEQ may consider actions including source identification, pollution control measures, and public outreach and education. Requires such actions be in accordance with the present law. Proposed law requires that any communication of collected data include explanations, context, applicable air standard data limitations, and relevant uncertainties. Proposed law provides that data produced by programs alone is not sufficient to show a violation of applicable law or permit. Further provides that DEQ shall not use data from community air monitoring programs that are not in compliance with proposed law for issuing a fine, penalty, or violation or for pursuing an enforcement action or proceeding. Proposed law prohibits use of data not in compliance with proposed law for alleging a violation of or noncompliance with present law or any other law for which the state has primary enforcement authority.
