Hearing Board

What is the Hearing Board authorized to do?

The Hearing Board is authorized to hear:

  • petitions by companies for variances;

  • petitions for abatement orders; (An abatement order requires a company operating out of compliance to take specific actions or to shut down its operation. This is a severe remedy normally reserved for serious violators.)

  • appeals by companies from the granting of permits, permit conditions, permit denials and suspensions, denials of emission reduction credits and denials of pollution control plans;

  • appeals by third parties.

After hearing all sides of a case in which individuals or companies come into conflict with South Coast AQMD rules and regulations, the Hearing Board weighs the evidence and reaches a decision.

It is important to note that the Hearing Board is not authorized to:
