CalEPA Unified Program- Proposed Regulations Available for Review: CERS 3
CalEPA has begun the formal regulatory rulemaking procedure with the Office of Administrative Law to adopt proposed revisions to existing Unified Program regulations, California Code of Regulations (CCR), title 27, division 3, subdivision 1, CERS Data Registry (Data Dictionary). The majority of the proposed amendments are considered non-substantial as they have relatively minor regulatory effects or impacts on regulated businesses and Unified Program Agencies (UPAs). The implications of the non-substantial proposed regulatory changes will likely have substantial impacts on UPAs regarding the ability to maintain parallel data exchange and provide methods to continue to utilize local data reporting and management systems independent of the California Environmental Reporting System (CERS).

The proposed revisions to the title 27 Data Dictionary language are briefly summarized as follows:

  1. Addition of available selections to existing CERS Data Fields for specifying the types of action taken relative to an Underground Storage Tank (UST) and the UST Operating Permit Application information.
  2. The ability for CERS to automatically generate a unique identification number for each UST in CERS.
  3. Addition of available selections to existing CERS Data Fields for specifying the use of an UST and its contents.
  4. Development of a new Chapter in the CERS Data Registry to capture and organize the four new CERS Data Fields for the APSA Program, which will provide the opportunity for regulated businesses to electronically report required information for regulated APSA facilities.

Non-substantial and substantial amendments, as well as the necessity and purpose for each, are detailed in the following rulemaking document:

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.
