Louisiana Emissions Reporting and Inventory Center

Home › Resources › Louisiana Emissions Reporting and Inventory Center

Description

Web interface providing tools for downloading actual and permitted emissions for either release points (facilities) within a defined radius, or summarized by parish. Downloadable data also includes detailed information about individual sources, including release parameters, e.g. flow rates, release heights, etc. Users can also download a point source emissions inventory for years 1991-2025.

Questions this resource can help answer

What are the emissions from different individual sources or source categories?
What are the emissions in an individual parish?
What are the trends in annual emissions for sources or locations over time?

How do I use this resource?

Emissions inventory reports can be generated for specific pollutants in two ways: 1) Use the "Radius Search" function to Identify a lat/long and a buffer radius to obtain emissions for each release point within the buffer, 2) Identify a pollutant and obtain aggregate emissions within each parish. In each case, you can download actual or permitted emissions, or both. You can also download prepared emissions inventory data files for multiple years.

Pro tips

To produce a report that covers all of the sources in Louisiana, you can use the generally recognized geographic center at Marksville (30.9683, -92.5367) and a radius of 500 km.

Detailed emissions obtained through "radius search" or "emissions by parish" are available for 2020-2025. Prepared emissions inventory data is available for 1991-2025.

Methodology

Regulated point sources of criteria air pollutants must submit an inventory of annual criteria pollutant emissions pursuant to the requirements of LAC 33:III.919. Detailed guidance for submitting emissions data is provided at https://deq.louisiana.gov/page/EmissionsInventory and https://deq.louisiana.gov/assets/docs/Air/EmissionsInventory/ERIC/ERICUserManual.pdf

Model

CoST

The Control Strategy Tool (CoST), developed in 2008, is part of EPA's Emissions Modeling Framework (EMF). CoST is used to estimate emissions reductions and engineering costs associated with control strategies applied to point and area sources of air pollutant emissions to support the analyses of air pollution policies and regulations.

MOVES

EPA's MOtor Vehicle Emission Simulator (MOVES) is a state-of-the-science emission modeling system that estimates emissions for mobile sources at the national, county, and project level for criteria air pollutants, greenhouse gases, and air toxics, available under EPA's Open Source Software policy.

SMOKE

SMOKE is primarily an emissions processing system designed to create gridded, speciated, hourly emissions for input into a variety of air quality models such as CMAQ, REMSAD, CAMX and UAM. SMOKE supports area, biogenic, mobile (both onroad and nonroad), and point source emissions processing for criteria, particulate, and toxic pollutants. For biogenic emissions modeling, SMOKE uses the Biogenic Emission Inventory System. SMOKE is also integrated with the on-road emissions model MOVES.
