Service Areas Across California

Headquartered in Newport Beach, AEC serves facilities throughout California — with deep roots in the South Coast air basin.

South Coast Air Basin

Our home turf. AEC engineers worked at the South Coast AQMD evaluating permits for Los Angeles, Orange, Riverside, and San Bernardino county facilities — and we have completed ERC/RTC trades throughout the district.

Other California Air Districts

We work with air districts statewide, applying the same permitting discipline used in the South Coast basin — from San Diego County in the south to the Bay Area and Central Valley districts in the north.

  • Permit applications & NSR
  • Compliance audits
  • Source testing coordination

Water & Waste Jurisdictions

Compliance doesn't stop at air. We handle permit and reporting obligations with the State and Regional Water Boards, county CUPAs, and sanitation districts such as LACSD.
