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.
Do you have questions about Retrofit options? We can help.

Who Does This Impact?
The Clean Air Construction Requirements are consistent across participating CAC Agencies; however, each agency applies the requirements at different contract thresholds.
Below is a list of the contract thresholds each agency has adopted:
City of Portland – all construction contracts over $1,000,000.
Multnomah County – all construction contracts over $500,000.
Metro – all construction contracts over $500,000.
Portland Community College – all construction contracts over $1,000,000.
Port of Portland – all construction contracts over $500,000.
TriMet – all public improvement contracts.
Washington County – all construction contracts over $500,000.
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.
