Planning and Assessment
Air Planning and Assessment covers a broad range of activities that protect public health by monitoring emissions, evaluating air data, and guiding clean air strategies.
Sections
Ambient Air Monitoring
LDEQ maintains a statewide monitoring network, made up of stationary and mobile ambient air monitoring stations. From these sites, personnel collect direct measurements of air pollutant concentrations, analyze, and interpret the data.
Stationary Ambient Air Monitoring Sites
Mobile Air Monitoring Lab (MAML)
Air Toxics Monitoring Program
Temporary Located Community Ambient Air Monitoring Program

Motor Vehicle Inspection and Maintenance
Louisiana has adopted a low enhanced Inspection and Maintenance (I/M) program for the control and abatement of motor vehicle emissions in the five-parish Baton Rouge ozone nonattainment area. Only vehicles registered in Ascension, East Baton Rouge, Iberville, Livingston, and West Baton Rouge parishes are subject to this rule.
Qualified Inspection Stations
The list of qualified inspection stations is maintained by the Department of Public Safety.
I/M Program
Out of State Vehicle Emissions Test
Emissions test for a vehicle that is currently located in Louisiana may be performed by any official Motor Vehicle Inspection (MVI) Station in the Baton Rouge ozone nonattainment area during normal inspection hours. A Vehicle Inspection Report (VIR) is available as the official test record.
State Implementation Planning (SIP)
The SIP is the state’s comprehensive plan to clean the air and meet federal air quality standards.
Plans in Development
Final SIP Revisions
Louisiana SIP activities can be found in EDMS under the SIP topic file under Agency Interest number 174156.
Diesel Emissions Reduction Act (DERA) Funding
The Diesel Emissions Reduction Act (DERA) provides funding to support projects that protect human health and improve air quality by reducing harmful emissions from diesel engines.
