Emissions Inventory | Louisiana Department of Environmental Quality

Reporting to the Criteria Pollutant Emissions Inventory or the Toxic Air Pollutant Emissions Inventory is based on many things and is determined by a review of the facility's air quality files, including the current air permit and application. Requirements to submit a Criteria Pollutant Emissions Inventory are outlined in LAC 33:III.919. Requirements to submit a Toxic Air Pollutant Emissions Inventory are outlined in LAC 33:III.Chapter 51.

Criteria Pollutant Emissions Inventories are due on April 30 of each year, pursuant to LAC 33:III.919. Toxic Air Pollutant Emissions Inventories are due on April 30 of each year, pursuant to LAC 33:III.5107.

Certification statements are generated by the ERIC system when an inventory is submitted. The Department does not accept altered or alternate versions of the certification statement. Certification statements may be re-printed from the ERIC system by viewing the summary page of the inventory and clicking the link to download the certification statement.

Yes. The Office of Environmental Services issues extensions on an individual basis through the Air Permits variance process. Requests must be submitted at least two business days before the April 30th deadline to be considered. See the Variance for ERIC Instructions for instructions and links to the application form.

Yes. however written notification from LDEQ is no longer needed to discontinue emissions inventory reporting. Each facility is responsible for determining eligibility and may discontinue reporting when there is no longer a reporting requirement for the full calendar year.

Criteria pollutants are those pollutants that EPA has set national air quality standards for, which are:

Ozone
Particulate Matter
Carbon Monoxide
Nitrogen Dioxide
Sulfur Dioxide
Lead

The inventory captures 4 of the 6 criteria pollutants as well as some additional pollutants. The pollutants in the inventory are:

Carbon Monoxide (CO)
Nitrogen Oxides (NO_x)
Particulate Matter (PM10 and PM2.5)
Sulfur Dioxide (SO₂)
Total Volatile Organic Compounds (VOCs)
Ammonia (NH₃)
Lead (Pb)
Butenes, isomers
Ethylene
Propylene

The inventory also captures toxic air pollutants (TAPS), and a list of these can be obtained in LAC 33:III.Chapter 51.

The Technical Fact Sheet on Non-VOCs gives guidance and lists for identifying VOCs and non-VOCs.

All other parishes are considered attainment for ozone. For more information, visit our Ozone Pollution and Prevention site.

Calcasieu Parish was considered nonattainment for ozone until June 2, 1997. At that time, Calcasieu Parish was considered attainment for ozone. However, during 1998, 1999, and 2000, Calcasieu Parish experienced six ozone exceedance days, activating contingency measures and requiring the area to report to Emissions Inventory at lower thresholds. This area included Cameron, Jefferson Davis, and Beauregard parishes.

In July of 2006, the Calcasieu area was released from the reporting to Emissions Inventory at lower thresholds and returned to attainment thresholds as required by LAC 33:III.919.
