California’s refineries in the Bay Area and the Los Angeles Basin and its Kern County oil fields operate under the strictest air rules in the nation. AIM™ EH&S runs Leak Detection and Repair (LDAR) programs across California with crews who have walked the units they monitor.
Which Rules Apply in California
Local air districts drive the program here — SCAQMD Rule 1173, BAAQMD Regulation 8, and San Joaquin Valley APCD rules impose component-level leak standards tighter than federal NSPS VV/VVa and refinery MACT CC, under CARB and EPA Region 9. We read the applicable rule for your facility instead of guessing.
What We Do
Method 21 component monitoring, OGI surveys, repair tracking against the regulatory clock, audit-grade recordkeeping, and program design — from single pads to refinery-scale unit counts.
Why California Operators Call Us
Air-district and EPA Region 9 experience, calibrated instruments, and defensible data every time. No fluff, no padded headcounts.
