SCAQMD LAP-Approved
Source Testing — SCAQMD LAP-Approved
Criteria pollutants. Air toxics. Full protocol-to-report service for permitted facilities across Southern California.
What We Test
Every Pollutant Your Permit Covers
We handle the whole job end–to–end — consultation against your permit, source test plan and protocol submitted to your governing officer, and the testing itself. Thirty–five plus years in, we take care of everything so your team can keep running.

Our Process
How It Works: Protocol to Report
Scope and Protocol
You tell us what equipment needs testing and what the permit says. We write the protocol and submit it to SCAQMD for approval.
Scheduling
We work around your production schedule. The test needs representative operating conditions — we'll coordinate with your operations team to find the right window.
On-Site Testing
Our crew runs the methods with calibrated analyzers that meet every regulatory spec. Gaseous pollutants get real-time analysis. Particulates and toxics get isokinetic sampling.
QA/QC and Data Reduction
Every data point gets checked against calibration records, method requirements, and your permit limits. If something looks off, we catch it on-site — not in the report.
Report
Complete source test report with calculations, supporting data, and documentation. Ready for SCAQMD submission within the 60-day window.
Experience Matters
Why Getting It Right the First Time Matters
A failed source test doesn’t just mean re–testing fees. It means another mobilization, another round of scheduling with your operations team, and a possible fine or no–operation order on that unit from your district. Every day in that window is a risk.
We’ve been permitted on every method we run for decades, across boilers, heaters, ovens, turbines, baghouses, oxidizers, scrubbers, and well beyond. Your test plan is built on that experience, not guesswork.
Schedule Your Test
Tell us what equipment needs testing and when your deadline is. We'll get you on the schedule.
