Portable tanking system and method

A method of providing substantially uninterrupted gas service during a temporary, primary gas service shutdown, comprising:

• coupling at least one gas cylinder to a portable tanking assembly, the tanking assembly comprising:
• a cart including a rear frame and a carrier frame coupled to and extending from the rear frame and supported on an axle with wheels,
• a caged regulation assembly coupled to the cart, the caged regulation assembly comprising a protective cage housing at least a portion of a regulation apparatus comprising an upstream supply end coupled to a downstream delivery end,
• the regulation apparatus including a primary regulator coupled to at least one relief valve, the at least one relief valve coupled to at least one downstream regulator, the at least one downstream regulator coupled to a water column gauge, the water column gauge coupled to at least one delivery valve;
• and
• electrically coupling and grounding the tanking assembly to a customer's gas service line;
• fluidly coupling at least one downstream valve to a gas service line, coupling a high pressure hose to the gas cylinder, and
• controlling a downstream flow of gas from the gas cylinder to the gas service line using the regulation apparatus;
• and
• monitoring at least one of supply and flow of gas to ensure substantially uninterrupted gas service during the temporary shutdown of the primary gas service.
