Oregon Facilities Facing State & Federal Air Quality Regs

Are you ready for both CAO and ICR Testing?

Dusk over a scenic river in Oregon with a lit-up bridge, and colorful flags. Tall chimneys and a industrial building are visible. Are you ready for the Oregon Cleaner Air regulations?

Between the ODEQ Cleaner Air Oregon (CAO), USEPA Greenhouse Gases (GHG), Information Collection Request (ICR) requirements, and all permits and emissions inventories—facilities are under pressure to deliver precise, defensible emissions data.


From source testing to risk modeling and permitting, Oregon facilities of all sizes are being held to highly technical toxic air contaminant emissions inventory reporting standards and selecting the right partner to deliver it will be critical.


What’s Driving the Demand?


1. Stack Testing & Emissions Monitoring

Oregon DEQ mandates rigorous stack testing which will require expertise with these methods :.

  • ODEQ Method 5 for PM from wood-fired boilers

  • ODEQ Method 7E for veneer and wood dryers

  • Experience with all other EPA methodology when ODEQ methods don't apply


We help clients not only meet these requirements but identify operational efficiencies through accurate data.
