CalEPA Unified Program

Effective July 1, 2018, various sections of California Code of Regulations, Title 27 were revised.  Revisions to Title 27 were necessary in order to reorganize, update and incorporate new parameters for administering the Unified Program and accomplishing the objectives of coordination, consolidation, and consistency in the protection of human health, safety, and the environment.  The majority of the adopted revisions are non-substantial, having no effect or impact on regulated businesses, Unified Program Agencies or state agencies having Unified Program responsibilities.  Substantial amendments have been adopted for the purpose of establishing consistency with current requirements, practices and procedures.
