The following proposed amended rules and regulations are tentatively scheduled for
hearings at upcoming Governing Board meetings in 2026. To verify whether scheduling
changes have occurred, visit South Coast AQMD’s website at www.aqmd.gov/home/
news-events/meeting-agendas-minutes, check the Rule and Control Measure Forecast
item on the most recent Governing Board meeting agenda, or call the Clerk of the
Board’s Office at (909) 396-2500. Copies of South Coast AQMD rules and regulations can
be downloaded from the website at www.aqmd.gov/home/rules-compliance/rules/

PAR 1401 – New Source Review of Toxic Air
Contaminants
Proposed Amended Rule 1401 will include new
toxic air contaminants identified by the California
Office of Environmental Health Hazard Assessment
or to revise health values for existing compounds.

Rule 1302 - Definitions defines terms used
in Regulation XIII – New Source Review, which
sets forth the federal and state mandated
pre-construction review program for new,
modified, or relocated sources for non-RECLAIM
air contaminants. The recently amended rule
updates the definition of Essential Public Service
to include composting operations under specific
circumstances. California Senate Bill 1383 (SB
1383) requires organic waste diversion from
landfills. It mandates statewide residential and
commercial organic waste collection to compost
or recycle food scraps, yard waste, and paper.
This amendment allows qualified composting
operations to draw from credits in the Priority
Reserve rather than buying them on the open
market as they implement state mandated organic
waste diversion. Contact: Michael Morris at

South Coast AQMD’s efforts to lower toxicity
of coatings, solvents, adhesives, and metal
working fluids
Smog is formed when Volatile Organic Compounds
photochemically react with oxides of nitrogen
(NOx) in the atmosphere and the reactivity of
VOCs varies by compound. Certain VOCs that
negligibly contribute to the formation of ground level
ozone or smog are considered exempt from
the regulatory definition, so they are used by
many coating manufacturers to comply with
South Coast AQMD rules. However, some exempt
compounds have potential toxic health risk. Two
exempt compounds, para-Chlorobenzotrifluoride
(pCBtF) and tert-Butyl Acetate (t-BAc), commonly
used in coatings, solvents, adhesives, and metal
working fluids, have recently been determined to
be potent carcinogens. South Coast AQMD has been
amending our VOC rules, evaluating each category
to assess if pCBtF and t-BAc are being used and
establishing a schedule for their phase out. To date,
South Coast AQMD has amended the following
seven VOC rules to address the health risk from
pCBtF and t-BAc with many more rules currently
undergoing amendments.
Rule 1168 - Adhesive and Sealant Applications
(Amended November 2022)
Rule 1151 - Motor Vehicle and Mobile Equipment
Non-Assembly Line Coating Operations (Amended
November 2024)
Rule 1171 - Solvent Cleaning Operations (Amended
June 2025)
Rule 1107 - Coating of Metal Parts and Products
(Amended December 2025)
Rule 1144 - Metal Working Fluids and Direct-
Contact Lubricants (Amended April 2026)
Rule 1124 - Aerospace Assembly and Component
Manufacturing Operations (Amended April 2026)
Rule 1136 - Wood Coating Operations (Amended
June 2026)
Additional information regarding VOCs, coatings,
rules, and exempt compounds can be found on
the South Coast AQMD’s VOC Compliance Page. Additionally, a document summarizing the pCBtF
and t-BAc phase out schedule for recently adopted
rules can be found here. Additional rules will be
added as they are amended.

SEPTEMBER
PAR 461 – Gasoline Transfer and Dispensing
Proposed Amended Rule 461 will provide an
alternative recordkeeping provision.
Contact: Neil Fujiwara at nfujiwara@aqmd.gov or
(909) 396-3512
PAR 1157 – PM10 Emission Reductions from
Aggregate and Related Operations
PAR 1157 will address community concerns and
further reduce PM10 emissions by strengthening
the existing requirements as well as expanding
applicability to include demolition and
construction transfer stations, and enhancing
recordkeeping and housekeeping provisions.
