Local Advantage
Why It Matters That We're Local
Three of the five largest source testing companies in California are headquartered out of state — Alabama, Texas, Connecticut. They fly crews in. That adds cost, adds scheduling complexity, and means you're working with people who may not know SCAQMD's specific procedural requirements the way a local firm does.
We've operated in Southern California since 1998. When SCAQMD amends a rule, we hear about it the same week. When a refinery in Torrance needs a RATA, we're there by morning.
Faster Scheduling
No cross-country coordination.
Lower Project Costs
No mobilization travel.
Emergency Response
Same-day when AQMD issues a notice.
Regulatory Fluency
SCAQMD rules, CARB requirements, local permit conditions.
