Current Regulatory documents for the Proposed CTR Amendments (2/9/22)
2020 Amendments Adopted, with Modifications
On November 19, 2020, CARB adopted amendments to the proposed Regulation for the Reporting of Criteria Air Pollutants and Toxic Air Contaminants (CTR) and to the Air Toxics “Hot Spots” Emission Inventory Criteria and Guidelines (EICG) Regulation. However, based on public comment received, the Board directed CARB staff to consider additional modifications to the regulations prior to finalizing the revisions. Staff will incorporate any revisions through a public "15-day" revisions process, including a workshop.
Additional materials, including prior workshop presentations are available on our Meetings & Workshops page.
