Residential Diesel Generator Engines

On March 17, 2005, the APCD Board adopted revisions to Rule 202, as required by state law. Diesel engines rated at greater than 50 brake-horsepower (bhp) are now required to obtain APCD permits. New engines require a permit before installation; owners/operators with existing engines were required to submit applications by no later than June 16, 2005.  If you own/operate an existing engine, and did not submit an application by June 16, 2005, your application is now overdue.  See Permit Application Material below.

Note: this page is for residential generators only. If this is a non-residential generator, please see this page.
