The NBS system is designed to prevent the formation of corrosive, damaging atmospheres in retail and commercial fuel storage tanks. The system is an intrinsically safe Environmental Corrosion Control method that inhibits or prevents the growth of bacteria, molds and yeasts that may occur in the ullage of tanks and produce acidic deposits that cause serious damage and failures to tank equipment.

Typically, retail tanks store routine and custom blends of diesel and biodiesel, gasoline and ethanol, and other commercial liquid hydrocarbon fuels. Additionally, these tanks are usually 50,000 gallon capacity or less, low pressure, and may be installed above or below ground.

Nitrogen gas blanketing of the headspace of tanks has proven to have many benefits. One such benefit is how the NBS changes the tank’s environment to prevent the conditions that provide water for germination and oxygen for respiration for colonies to grow. Eliminating water and oxygen prevents serious damage that has led to failure of fuel storage containment boundaries – leaking primaries.

API 2000 6th and 7th Editions address environmental corrosion control for large fuel tanks. These protocols are in proven use at refineries, bulk fuel storage facilities, bulk fuel transfer terminals and airports worldwide. The consensus of a group of state regulators, fueling system component manufacturers, and operators of retail and commercial fueling sites is that the conditions causing corrosion damage to fueling system components in retail market fuel storage equipment can best be addressed by adapting API environmental corrosion control (API 2000 6th and 7th editions) protocols. These adapted protocols should be one part of a comprehensive program that seeks to identify corrosive environments and prevent or stop damage to retail fueling equipment.
