Cal. Code Regs. tit. 17, § 95484
(b) Automatic Acceleration Mechanism. Starting May 15, 2027, and every quarter after, the Executive Officer will announce on the LCFS website whether the Automatic Acceleration Mechanism has been triggered and the cumulative number of times that the Automatic Acceleration Mechanism has been triggered. This announcement will take place on February 14, May 15, August 15, and November 15 of each year, or the following business day, if the announcement date falls on a weekend or holiday.
(2) The Automatic Acceleration Mechanism is triggered when the conditions in both subsections (A) and (B) below are met, and if it was not triggered in the immediately prior four quarters.
(A) The Credit Bank to Average Quarterly Deficit Ratio exceeds 3:
)
where:
Credit Bank20xx is the final credit bank for the program as calculated at the end of the four quarters preceding the quarterly Automatic Acceleration Mechanism announcement; and
Deficits20xx is the total number of annual deficits generated under the program as calculated at the end of the four quarters preceding the quarterly Automatic Acceleration Mechanism announcement.
(B) Credit Generation exceeds Deficit Generation:
)
where:
Credits20xx is the total number of credits generated under the program as calculated at the end of the four quarters preceding the quarterly Automatic Acceleration Mechanism announcement; and
Deficits20xx is the total number of deficits generated under the program as calculated at the end of the four quarters preceding the quarterly Automatic Acceleration Mechanism announcement.
(c) Updating the Benchmark Schedules. Starting January 1, 2028, the compliance year for which an average carbon intensity benchmark applies will also take into account the number of times the Automatic Acceleration Mechanism has been triggered pursuant to section 95484(b).
(d) Benchmarks for Gasoline and Fuels used as a Substitute for Gasoline. Starting in 2028, the defined average carbon intensity benchmarks for each future year will be advanced by one year each time the Automatic Acceleration Mechanism has been triggered pursuant to section 95484(b).
