Featured Project: SCAQMD Rule 1166 SVE Pilot Near School
100% Compliant BTEX, TCE & PCE Removal – Zero Complaints in 90 Days
Executive Summary A remediation contractor needed a 90-day pilot soil vapor extraction (SVE) system within 2,000 ft of a public school in the South Coast AQMD. Target contaminants: BTEX, TCE, and PCE. Because of the ultra-sensitive location, zero detectable emissions were allowed under SCAQMD Rule 1166 and the district’s school-proximity policy.
Envent delivered a pre-permitted, self-contained SVE trailer the next day. Result: non-detect stack samples every day, zero odors, zero complaints, and full data package that green-lit the permanent system.
Project Snapshot
- Location – South Coast AQMD, California
- Duration – 90-day pilot
- Contaminants – BTEX, Trichloroethene (TCE), Tetrachloroethene (PCE)
- Equipment – Pre-permitted 500 SCFM SVE trailer
- Outcome – Non-detect emissions, immediate permanent order
The Challenge – SVE Within 2,000 ft of a School
- Heightened SCAQMD scrutiny on school-adjacent sites
- Must achieve non-detect at stack for BTEX, TCE, PCE
- Prove performance before $500K+ capital commitment
