CAC program summary:
The Clean Air Construction (CAC) Program is a collaboration among public agencies in the Portland Metro Area to reduce diesel emissions on construction projects in their areas.
These emissions reductions will be accomplished in 2 ways:
-
Enacting idle reduction procedures on construction sites.
-
Upgrading older diesel equipment via grant-funded retrofits.
This will also involve implementing a regional program to verify compliance with the requirements. There are various state grant programs available to assist with the costs of retrofitting your older diesel construction vehicles.

Idle Reduction Requirements on CAC Agencies Construction Projects
Excessive idling contributes to harmful emissions and in an effort to curb this the following steps must be taken* to reduce the idling of diesel equipment:
• All nonroad diesel equipment must shut down after five (5) minutes of inactivity, and
• All nonroad diesel equipment shall have decals/prompts visible to the operator to remind them to shut down the equipment after five (5) minutes of inactivity, and
• Contractors will post “Five Minute Limit” signs in high foot traffic areas of the job site, visible to workers, and
• Contractors will ensure all diesel equipment operators are aware of the policy.
* There are some exemptions to the above idle reduction requirements.
Diesel Engine Requirements and Phase-In Schedule of Retrofits
On January 1, 2022, “all diesel-powered nonroad construction equipment greater than 25 horsepower and all on-road diesel dump trucks and concrete mixers…” must meet CAC Engine Requirements.
Diesel emissions control device retrofits must maximize diesel particulate matter reductions.
