Calendar Year (CY) 2019 Annual Emissions Report (AER) Deadline March 17, 2020 by 5:00 p.m.

The South Coast Air Quality Management District (South Coast AQMD) Annual Emissions Reporting (AER) program was developed to track emissions of air contaminants from permitted facilities.  Fees for emissions of air contaminants are assessed based on the reported data. These fees help to cover the costs of evaluating, planning, inspecting, and monitoring air quality efforts.  Under this program, those who emit more, pay more toward air pollution control efforts – and at the same time are given an incentive to reduce emissions.

The data collected by AER is used to update the comprehensive emissions inventory for the South Coast AQMD, which includes Orange County, the non-desert portions of Los Angeles and San Bernardino counties, and the Riverside county areas west of the Palo Verde Valley.

This annual emissions inventory of pollutants and source categories is essential to effectively design and evaluate clean air strategies to comply with state and federal public health standards.  The compiled inventory is published in each update of the Air Quality Management Plan.

The South Coast AQMD requires the filing of an Annual Emissions Report and payment of annual fees based on a facility's emission of air contaminants, as specified in Rule 301, subdivision (e) and paragraph (l)(10).  Facilities required to file an annual emissions report include the following:

• Every facility that receives an Annual Emissions Reporting notification from South Coast AQMD, regardless of the estimated annual emissions levels, even if no fees are due, to update the facility's emissions records.

• Every facility that has estimated annual emissions of four (4) or more tons of either 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 (CO).

• Every facility subject to the AB2588 Program for reporting quadrennial updates to its toxics emissions inventory (per Health and Safety Code Section 44344).

Furthermore, facilities are required to report their emissions (both criteria and toxics) for calendar year and pay their emission fees using the current fee rate specified in Tables III and IV of Rule 301(e).  Facilities also have 75 days from the official due date (January 1st) to submit both the emissions report and fee payment to avoid being subject to late filing surcharges.

REPORTING SYSTEM (AER Reporting Tool)

South Coast AQMD has developed a web-based emission reporting tool to assist facilities to enter operational data, calculate emissions and fees, and submit the emission data report.  Users are encouraged to navigate this site and be familiar with the material presented including tutorials, help & support, technical guidance documents, and other useful information.  This web-based program can be accessed at the link below.  Users must register to use the AER Reporting Tool.
