• Preventive Maintenance Guide for Fuel Storage TanksA well-built preventive maintenance program for underground tanks prevents leaks, fines, and shutdowns. This guide builds it component by component, with frequencies by standard.
• Underground fuel tank installation guide (PEI RP100)A poorly executed underground tank installation is not discovered on ribbon-cutting day: it is discovered years later, when the backfill gives way or the cathodic protection never closed the circuit. This guide follows the flow of PEI RP100-17.
• Oil/water separator (API separator) at fuel stations: operation, cleaning, and MIAMBIENTE complianceHow the oil/water separator (API separator) operates at Panamanian stations, cleaning frequency, MIAMBIENTE compliance, and the consequences of omitted maintenance.
• Sumps and spill buckets at fuel stations: inspection, draining, and spill preventionHow to inspect and maintain dispenser sumps and spill buckets at Panamanian stations. Frequency, failure signs, and spill prevention under MIAMBIENTE.

Glossary

STP (submersible turbine pump)

Submersible Turbine Pump. A centrifugal pump inside the tank that pressurizes fuel and pushes it to the dispensers when a customer fuels up.

Sump

A liquid-tight box over the tank or under the dispenser. It contains possible spills and protects the pump-to-pipe connections from the ground.

Drop tube

A vertical pipe inside the tank through which the tanker truck discharges fuel. It houses the valve that stops filling at 95%.

Interstitial space

The gap between the inner and outer wall of a double-walled tank or pipe. Sensors placed there detect a leak before it reaches the ground.
