Compliance, Monitoring, and Enforcement (CME) Data

Regulators must submit their Compliance, Monitoring and Enforcement (CME) data into CERS no later than within 30 days after the end of the quarter containing a CME transaction’s action date (of each completed fiscal year quarter [CCR Title 27, Division 1, Subdivision 4, §15290(b)]). Regulators can meet this requirement by:

    • Manually entering CME data using the CERS Regulator Portal, or
    • Using CERS Electronic Data Transfer(EDT) Services, or
    • Using the CME Data Upload Template to upload CME data to CERS in bulk. In order to successfully be uploaded into CERS using the CME Data Upload Template, the data must conform exactly to the structure of the CME Data Upload Template (having identical columns, headings and order, as well as worksheet names), and
      CalEPA recommends uploading no more than 500 CME data entities per upload (which can take 60-100 seconds to upload/process). Larger batches of CME data should be split into multiple spreadsheets and uploaded individually.
      All CME data must include the complete detail record fields identified in the CERS Regulatory Portal and defined in the CERS Data Registry, and the applicable CERS3 Business Rules.
CME data must be submitted to CERS in accordance with the following fiscal year quarters:
