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

The California Air Resources Board (CARB) passed AB 617, which can require government and industrial facilities to prepare toxics reports, implement Best Available Retrofit Control Technology (BARCT) permitting, and conduct fenceline monitoring. Yorke Engineering, LLC can help you plan for and implement all aspects of monitoring and compliance with AB 617.

Stationary Source Reporting of Criteria and Air Toxic Pollutants

Stationary source reporting started in Q1 2019 for 2018 data and applies to facilities that:

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

2018/2019 Reporting Requirements:

  • Criteria and toxic emissions at the device/process level;
  • Throughput and/or calculated emissions; and
  • Data submittal to the local Air District no later than May 1st (some districts may be earlier).

Yorke has prepared hundreds of similar toxic and criteria emission reports, so we can easily prepare AB 617 reports for you.

Stationary Source BARCT Requirements

BARCT is the required addition of control devices to existing sources. Starting in 2019, BARCT will begin to be implemented by air districts. The districts will focus on the larger sources until around 2022 (refineries, cement manufacturing, organic storage tanks, and more depending on the local Air District). 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, the enclosure of sources and venting to controls, and many other requirements. The BARCT permitting process will be the same as District permitting.

Community Air Protection Program

  • Source Testing by Facilities;
  • Fenceline Monitoring by Facilities; and
  • Detailed Inventories from Permitted Sources, Including Indirect (Mobile) Sources.

Industrial Mobile Sources – Potential Impacts of AB 617

  • New Clean Car, Bus, and Truck Standards;
  • New Off-Road Diesel Requirements;
  • New Forklift Requirements; and
  • Cleaner Standards at Ports.
