What Is A Protected Above Ground Tank?

 

Above ground storage tank requirements

 

The following procedures should be followed in addition to all applicable Federal, State and Local laws.

 

Installation:

 

A permit is required for the installation, removal, operation, repair or alteration of ASTs used to store and dispense flammable or combustible liquids. Applicants must get a license from the Tucson Fire Department and Department of Development Services for AST’s. 

 

The construction plans must be submitted with an application for a license. The applicant will present a site plan showing the tank’s position with respect to adjacent buildings and lines of the land. The plans shall include the design, specifications and details. The site plan includes tank specifications.

 

Tanks must meet a nationally recognized testing laboratory listing such as Underwriters

Laboratory, ASME, or designed and built in accordance with recognized engineering

Standards.

 

  • The tank location may depend on the tank size and the type of liquid that is held. Zoning restrictions include limits on tank capacity, large setback distances from residential zoning, and criteria for tank screening. Installation owners will review all applicable regulations before making a decision to replace UST’s with AST’s.

 

  • Some secondary containment means are required and must hold 100 percent of the largest tank’s capacity. The secondary containment may be a double-wall tank or a diked area tank. If a diked area is used as a secondary containment it is necessary to provide a means to remove water.

 

  • Vent piping for liquids of Class I, II or IIIA must be mounted not less than 12 feet above adjacent ground level and not less than 5 feet from the opening of a structure. It also requires emergency venting.

 

  • Dispensing shall be from a pump specified, drawing from the top of the tank. Gravity discharge tanks are forbidden unless they are installed on a temporary site. The location of the dispensing may not be less than 10 feet from any building or property line, and at least 20 feet from all fixed ignition sources. To avoid siphoning, tank openings, tubing, and valves should be fixed.

 

  • Guard posts or other means for the defense of tanks from vehicular damage shall be provided. Tanks must be labeled with the name of the drug, and no signs of smoking. To avoid static electricity the tanks must be grounded or bonded. A 2A20BC fire extinguisher or larger one must remain available at all times.
