Assembly Bill 617 – Reporting, BARCT, Monitoring, and Mobile Sources

The California Air Resources Board (CARB) passed AB 617, which requires many government and industrial facilities to prepare criteria and toxics reports, implement Best Available Retrofit Control Technology (BARCT), and conduct source-specific or fenceline monitoring for the Community Air Protection Program. Yorke Engineering helps facilities plan for and implement all aspects of monitoring and compliance with AB 617.

> Reporting of Criteria and Air Toxic Pollutants

Reporting to local air districts started in 2020 for 2019 data of criteria and air toxic pollutants. Facilities are required to report if they:

  • Fall under mandatory reporting for greenhouse gases (GHGs);
  • Are permitted to emit 250 tons of a criteria pollutant; or
  • Are designated as high priority for toxics by the local Air District.

2019 data was collected as specified by the air districts.

Starting in 2021 (for GHG and criteria pollutant facilities) or 2022 (for high priority facilities for toxics), additional information will be required to be reported to the air districts and subsequently sent to CARB. Data is required to be submitted to the local Air District no later than May 1st (some air districts may be earlier), and each District is required to submit the data to CARB by August 1st. The reported emissions data will be publicly available.

Yorke Engineering has prepared hundreds of similar toxic and criteria emission reports, so we can easily assist with preparation of these reports.

> Stationary Source BARCT Requirements

BARCT is the required addition of control devices and technologies to existing sources. Starting in 2019, BARCT will begin to be implemented by the air districts. The districts will focus on larger sources until around 2022 (e.g., refineries, cement manufacturers, organic storage tanks, and more). BARCT will be required at more facilities and smaller sources over time, and could include high-efficiency particulate air (HEPA) filters, low-nitrogen oxide (NOx) burners, scrubbers, adsorbers, enclosure of sources, and/or venting to controls, among other requirements. Before implementation, control devices must be permitted with the Air District.

> Ambient and Fenceline Monitoring

Yorke can provide compliance assistance related to the Community Air Protection Program implemented by CARB, including:

  • Source testing oversight and support;
  • Fenceline monitoring; and
  • Detailed emissions inventories.

> Industrial Mobile Sources

We help facilities navigate and plan for mobile source regulations. Potential impacts of AB 617 on mobile source compliance and reporting requirements may include:

  • New Clean Car, Bus, and Truck standards;
  • New Off-Road Diesel requirements;
  • New Forklift requirements; and
  • Cleaner standards at ports.
