NOTICE ! !

TIER 3 INFORMATION FOR ENGINES 50-99 HORSEPOWER: Effective January 1, 2008, engines rated between 50 to 99 bhp transitioned from Tier 2 standards to Tier 3 standards.  Engines rated between 50 to 99 bhp that currently meet Tier 2 standards will be accepted until June 30, 2008.  Effective July 1, 2008, engines rated between 50 to 99 bhp will need to meet Tier 3 standards or show proof of California residency.  Engines that require proof of California residency documents will be subject to the registration fees listed on Form 1-B.

Registration fees have changed effective 4/27/07. See Form 1-A for information on the new fees. For more information about other changes, see Regulation Activities below.

The Air Resources Board adopted revisions to accept "resident" Tier 1 and Tier 2 engines that do not meet the current emission standard in effect at the time of registration. PERP is currently accepting applications for all Tier 1 engines and also Tier 2 engines rated between 100 BHP and 750 BHP if documentation of operating in California at any time between March 1, 2004, and October 1, 2006, is submitted with the application. Documentation can include company equipment inventory, purchase records, usage records, or maintenance records. Form 2A must be submitted with the residency documentation.

These Tier 1 and Tier 2 engines that do not meet the current emission standard must also pay an increased fee for registration that includes back registration fees, back inspection fees, and current registration fees. The amount of the fee will be based on year of purchase, year of manufacture, or Tier 2 start date, depending on certain criteria.

The revisions also included provisions to allow registration of "stock" Tier 2 engines within six months after the change to Tier 3. No additional fees are required for these engines.
