Diesel Internal Combustion Engine (DICE) Air Toxic Control Measure

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 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.  Per the October 18, 2007 updates to the ATCM, Agricultural engines are required to obtain a Registration. See Permit Application Material below.
