New Regulator Reports!
Three new reports have been released in the Regulator portal. The new reports are focused on Facility Compliance information and are intended to replace several legacy CUPA reports. The following are included in the new reports package:

Summary Enforcement Report: This report replaces the legacy "Report 4" CUPAs were required to submit as hard copy until 2013. This report will provide a summary of enforcement activities for regulated facilities for each program element.

Summary Regulated Facilities by Unified Program Element Report: This report replaces the facility count portions of the legacy "Report 2" and "Report 3" CUPAs were required to submit as hard copy until 2013. This report will summarize the count of regulated facilities for each program element managed by the selected CUPA.

Summary Regulated Facility Inspections Report: This report replaces the inspection related portion of the legacy "Report 3" CUPAs were required to submit as hard copy until 2013. This report will display the number of regulated facilities along with the number of routine and other inspections.

Title 27 Regulation Proposed Language Available for Informal Comments 
In July 2016, CalEPA hosted four informal regulatory workshops throughout the state to share and discuss the proposed amendments to the Unified Program regulations contained in subdivision 4 of Title 27 of the California Code of Regulations. The draft regulations can be accessed directly by clicking here, or from the Unified Program Laws and Regulations webpage (  Proposed changes to the regulations can be distinguished by text formatting; existing text in strikethrough format is proposed for deletion and new proposed text is underlined.

CalEPA will formally begin the regulatory rulemaking procedure with the Office of Administrative Law in November 2016, which will include a formal public comment period and a public hearing.

The proposed amendments include deletions of data dictionary elements for the Underground Storage Tank program that are no longer used; trade secrecy claims reported in the California Environmental Reporting System (CERS); Unified Program Agencies reporting the final disposition of complaints in CalEPA's Environmental Complaint Management System; and changes to CUPA-to-State reporting requirements and report formats. Other non-substantial changes include clean-up of regulatory language.

Businesses Must Report Electronically to CERS or a Local Reporting Portal All businesses must now submit Unified Program-related information to CERS instead of on paper forms. Alternatively, some CUPAs have developed local web portals that businesses may choose to use to meet this requirement. More information...

Are you a Multi-Facility/Multi-Jurisdictional Business?
If your business/organization operates multiple CUPA-regulated facilities located in multiple CUPAs, CERS now supports creation of a single corporate identity that allows consolidated management of ALL of your facilities by one or more authorized users. To establish a multi-facility business and consolidate any existing CERS facilities under your business, you need to submit documentation to Cal/EPA.

What is CERS?

The California Environmental Reporting System (CERS) is a statewide web-based system to support California Unified Program Agencies (CUPAs) and Participating Agencies (PAs) in electronically collecting and reporting various hazardous materials-related data as mandated by the California Health and Safety Code and new 2008 legislation (AB 2286). Under oversight by Cal/EPA, CUPAs implement Unified Program mandates that streamline and provide consistent regulatory activities.
