Emissions Inventories

Annual air emissions inventories of criteria and toxic pollutants are a common requirement in both EPA and local regulations. Davenport engineering has experience calculating air emissions from a wide variety of sources in petroleum refineries, chemical plants, manufacturing facilities, and more. We have prepared full-facility air emissions inventories to comply with regulations from the California Bay Area and South Coast AQMDs, the Washington State Department of Ecology, and the EPA (as part of the multimedia Toxic Release Inventory).

SCAQMD Annual Emission Report (AER)

AER - Annual Emissions Reporting

The South Coast Air Quality Management District (SCAQMD) is the local air quality governing board that maintains jurisdictional oversight of the four counties that comprise the SCAQMD which includes the counties of: Los Angeles, Orange, Riverside and San Bernardino located in southern California. The SCAQMD requires businesses subject to the Annual Emissions Reporting program to file an Annual Emission Report (AER) and payment of fees based on a facility’s annual emissions.  Facilities required to file an AER include:

  • Facilities that receive an AER notification package from SCAQMD
  • Facilities that have estimated annual emissions of four (4) or more tons of sulfur oxides (SOx), volatile organic compounds (VOCs), nitrogen oxides (NOx), specific organics (SPOG), particulate matter (PM), or emissions of 100 tons per year or more of carbon monoxide or emissions of specific Toxic Air Contaminants and ozone depleting compounds (TAC/ODC) in excess of the thresholds provided in Table IV of Rule 301.
  • Facilities subject to the AB2588 Program for reporting quadrennial updates to their toxic emissions inventory (per Health and Safety Code Section 44344)

Effective starting the 2014 reporting year, the SCAQMD requires use of a relatively new web based AER reporting tool for annual emissions.  SCAQMD believes that the new reporting tool allows facilities to better track their emissions while facilitating emissions reporting on a specific device/equipment basis. Complete details on the new AER reporting tool can be found by clicking here.
