Notices for New BACT Determinations
The public participation process in BACT determinations was enhanced to include technical review and comments by a focused Scientific Review Committee (SRC) at periodic intervals, prior to the updates of the South Coast AQMD BACT Guidelines. At the same time, a 30-day notice period has been established for the SRC and interested persons to review and comment on South Coast AQMD BACT determinations that result in BACT requirements that are more stringent than previously imposed BACT, the following are notices of new BACT determinations that are more stringent than prior BACT requirements by South Coast AQMD.
