The 2026 South Coast AQMD rule calendar has
planned over two dozen rule amendments and
adoptions in the upcoming year. These rules will
assist in implementing control measures in the 2016 and
2022 Air Quality Management Plans, along with the 2024
PM Plan to reduce emissions to attain state and federal air
quality standards, reduce health risks or exposures from air
toxics, and fulfill the air quality objectives approved in the
Assembly Bill 617 Community Emission Reduction Plans,
as well as resolve or clarify rule provisions.
Upcoming rule activity includes:
PM Reduction Activities – strengthen requirements from
operations at aggregate facilities to reduce particulate matter
emissions affecting surrounding neighborhoods; establish
requirements when operating air curtain incinerators from
forestry and agricultural waste management operations.
Further Control on Carcinogens – update toxic rules
to provide Volatile Organic Compound limit relief during
reformulation of aerospace, wood, marine coatings,
lubricants, and solvent degreasers to remove pCBtF and
tBAc; and further update toxic rules controlling hexavalent
chromium from metal heating operations as well as establish
requirements for commodity fumigation operations.
Update List of Toxic Air Contaminants – include
new contaminants identified by the California Office of
Environmental Health Hazard Assessment.
New Source Review - revise provisions to address
facilities that are transitioning from RECLAIM as well
as consideration of options for sources of offsets for
composting and renewable natural gas operations.
Monitoring – seeking to require fenceline monitoring of
metal toxic air contaminants at metal shredding facilities
and public notification when emissions exceed certain
thresholds; establish requirements to conduct monitoring
and sampling for those facilities identified as significant
high-risk level for a gaseous toxic air contaminant.
