SCAQMD Compliance Testing — LAP-Approved Since 1998

Source testing, CEMS audits, and permit-required emissions monitoring for facilities operating in the South Coast Air Quality Management District.

Compliance Requirements

What SCAQMD Requires

Every permitted facility in the SCAQMD jurisdiction — that's Orange County, LA County, western Riverside, and southwestern San Bernardino — has testing obligations. Your permit spells them out. The penalties for ignoring them are severe.

Equipment / Rule How Often
Boilers ≥ 10 MMBtu/hr (Rule 1146) Every 3 years
Boilers 2–10 MMBtu/hr (Rule 1146.1) Every 5 years
Combustion units with SCR/ammonia (Rule 1147) Quarterly — drops to annual after 4 consecutive passes
CEMS RATA (Rules 218.2/218.3) Every 4 calendar quarters
Permit-specific conditions Per your permit schedule

Corporate fines reach $1,000,000 per day per violation. Each day counts separately.

Regulatory Expertise

Rules We Work Under Weekly

This isn't a list we pulled from a website. These are the rules our crew works under regularly:

1146 / 1146.1

Boiler and heater NOx/CO

1147 / 1147.2

Miscellaneous combustion equipment (ovens, furnaces, afterburners, calciners)

1135

Electricity generating facility emissions

1109.1

Refinery operations, AB 617 BARCT

218.2 / 218.3

CEMS general provisions and performance specs

1110.2

Gaseous-fueled engine emissions

462

Organic liquid transfer

If you have a permit-to-operate in the South Coast Air Basin, we've probably tested under the rule that governs your equipment.

Regulatory Update

RECLAIM Is Over. The Testing Isn't.

The SCAQMD NOx RECLAIM program ended after 30 years. Facilities that managed compliance through trading credits now face equipment-level emission limits under new landing rules.

Here's what changed:

  • Every permitted unit needs individual source testing to show BARCT compliance
  • CEMS certified under the old Rules 218/218.1 must now meet 218.2/218.3 specs
  • NOx or VOC increases trigger Federal Major Modification review under Title V

We tested RECLAIM facilities from day one. Marathon Oil Refinery. Ultramar. PBF Torrance Refining (previously known as ExxonMobil Refinery). Multiple SCAQMD RECLAIM compliance and certification programs over two decades. The transition isn't abstract to us — we've been on those stacks.

Don't Wait for the Notice of Violation

Not sure what your facility owes under the current rules? We can review your permit conditions and lay out exactly what testing applies, which methods, and when it's due.
