The California Air Resources Board (CARB) has recently made changes to its statewide Portable Equipment Registration Program (PERP), as well as the Airborne Toxic Control Measure (ATCM) for Diesel Particulate Matter (DPM) from Portable Engines Rated at 50 Horsepower and Greater. In response, the San Diego Air Pollution Control District (SDAPCD) has proposed amendments to Rules 12 and 12.1, which relate to Registration of Specified Equipment and Portable Equipment Registration, respectively. Rule 12.1 provides an option for voluntary registration of portable engines and other equipment in San Diego County instead of having to obtain a permit to operate. Rule 12 applies to other stationary and portable equipment that are not eligible for registration under 12.1.

Other highlights of the proposed amendments to the rules are noted below.

  • A reduction in particulate matter (PM) emissions to 82 pounds per day from 100 pounds
  • A removal of daily volatile organic compound (VOC) emissions limits
  • Coverage of rock drills under rule 12.1 instead of 12
  • Addition of an "Ineligible Equipment" section that clearly defines what equipment is not eligible for registration under Rule 12.1
  • Addition of a "Registration of Emission Units" section outlining the registration process and requirements
  • Addition of an "Administration of Certificate of Registration" section that defines a current registration certificate, expiration of a certificate, transfer of ownership, etc.
  • Additional and revised definitions to explain rule wording
  • Removal of outdated sections
  • Updating of all sections for consistency with state regulations
