ATCP 93.350(6)(c) (c) Emergency venting.

ATCP 93.350(6)(c)1. 1. Atmospheric, low-pressure and high-pressure aboveground tanks shall have emergency venting to ensure that the maximum pressure for the tank is not exceeded.

ATCP 93.350(6)(c)2. 2. Emergency venting shall be designed by a qualified engineer in accordance with good engineering practices.

ATCP 93.350 Note Note: Examples of emergency venting include larger or additional open vents, pressure-vacuum valves, pressure relief valves, a gauge hatch that permits the cover to lift under abnormal internal pressure or a manhole cover that lifts when exposed to abnormal internal pressure.

ATCP 93.350(6)(d) (d) Labeling of pressure relief valves.

ATCP 93.350(6)(d)1. 1. Where safety, pressure relief or vacuum relief valves are used, each valve shall be permanently labeled with all of the following information:

ATCP 93.350(6)(d)1.a. a. The name or identifying trademark of the manufacturer.

ATCP 93.350(6)(d)1.b. b. The manufacturer’s design or type number.

ATCP 93.350(6)(d)1.c. c. The pipe size of the inlet.

ATCP 93.350(6)(d)1.d. d. The set pressure or vacuum, in pounds per square inch gauge.

ATCP 93.350(6)(d)1.e. e. The full open pressure or vacuum, in pounds per square inch gauge.

ATCP 93.350(6)(d)1.f. f. The capacity at the indicated pressure or full open vacuum, in either cubic feet of gas per minute or cubic feet of gas per hour.

ATCP 93.350(6)(d)2. 2. The labeling shall be provided either on the valve itself or on a plate securely fastened to the valve.

ATCP 93.350(7) (7) Temperature monitoring.

ATCP 93.350(7)(a) (a) Temperature indicators and corresponding alarms shall be provided for storage tanks where heat from a reaction could cause damage to the system or a release to the environment.

ATCP 93.350(7)(b) (b) Heated or cooled tanks shall be equipped with appropriate thermal controls and gauges.

ATCP 93.350(7)(c) (c) Protection against overheating or overcooling shall be provided for heated or cooled tanks in accordance with generally accepted engineering practices.

ATCP 93.350 Note Note: Means of protection may include temperature controllers, insulation, alarms, cooling systems, and special material selection.

ATCP 93.350(8) (8) Leak detection for underground tank systems.

ATCP 93.350(8)(a) (a) Underground storage tank systems that contain federally regulated hazardous substances shall be equipped with a leak detection system which will detect a leak in the primary containment of the tank and piping.

ATCP 93.350(8)(b) (b) The leak detection method shall be capable of meeting the requirements in s. ATCP 93.510, except as provided in par. (c).

ATCP 93.350(8)(c) (c) Other methods of leak detection may be used if approval from the department is obtained before the installation and operation of the new UST system.

ATCP 93.350(9) (9) Corrosion protection. Corrosion protection shall be provided in accordance with s. ATCP 93.520 for underground storage tank systems or s. ATCP 93.400 for aboveground storage tank systems.

ATCP 93.350(10) (10) Identification and labeling.

ATCP 93.350(10)(a) (a) Transfer points shall be labeled with the name of the substance transferred.

ATCP 93.350(10)(b) (b) Aboveground tanks storing hazardous substances within the scope of this section shall be identified and labeled in accordance with s. ATCP 93.400 (7).

ATCP 93.350 Note Note: Section ATCP 93.400 (7) requires conformance with NFPA 704.

ATCP 93.350(10)(c) (c) All tanks on a property shall have a unique tank identification number that is readily visible to emergency response personnel.

ATCP 93.350(11) (11) Inspections, changes in service, tank closure, and releases from a tank.
