The following tips and guidance can help improve environmental outcomes and reduce costs during site cleanups.

Soil Excavation

• Use surgical excavation techniques that minimize land disturbance.
• Segregate soil during excavation activities so that non-impacted soil can be used as backfill.
• Recycle all reusable fluids.
• Investigate alternate shipping methods, such as rail for transferring excavated soil.

UST Removal/Replacement

• Prevent spills and control odors when emptying a tank.
• Use advanced equipment for release prevention and detection when replacing underground storage tanks.
• Collect soil samples at multiple depths. This additional data may be used by ADEQ and the environmental professional to evaluate if the release can be closed without additional samples being required from the UST owner during another investigative field event.
• Coordinate UST removal and soil over-excavation activities.
