Module 2

Equipment Installation & Compliance

Critical procedures for installing storage systems, detecting leaks, and ensuring environmental compliance.

2.1Installation Methods

UGST Installation

  • Excavation: Must be deep enough for tank + bedding + cover (usually 36" min cover).
  • Anchoring: Use "deadman" concrete anchors to prevent tank flotation.
  • Backfill: Pea gravel or crushed stone is mandatory to support fiberglass walls.

AGST Installation

  • Foundation: Reinforced concrete pad required to support concentrated weight.
  • Setbacks: Strict separation distances from property lines (NFPA 30).
  • Protection: Heavy-duty bollards are mandatory on all traffic-facing sides.

2.2Leak Detection & Monitoring

Automatic Tank Gauge (ATG)

An electronic probe inside the tank that constantly measures fuel level, water level, and temperature. It can detect a leak as small as 0.1 gallons per hour.

Interstitial Monitoring

Sensors placed in the dry space between the inner and outer tank walls. Any liquid detection (fuel or water) triggers an immediate alarm.

2.3Testing Requirements

Commissioning Tests

HydrostaticFilling sumps/buckets with water to verify tightness.
PneumaticPressurizing pipes with air (50-100 PSI) and soaping joints.
PrecisionAdvanced 3rd party test for 0.1 GPH leak certification.

Interactive Exercise
