36 Liquid level indicator requirements for below ground stationary tank for hazardous liquids

(1) A below ground stationary tank used to store hazardous liquids must have a liquid level indicator that indicates the actual liquid level in relation to the safe fill level.

(2) A liquid level indicator that is part of a below ground stationary tank must be designed, constructed, and installed to resist heat and impact to which the liquid level indicator may be subjected in any reasonably foreseeable situation.

Part 7

Obligations and restrictions for below ground stationary tanks for gases

37 Design, construction, and installation of below ground stationary tank for gases

Every below ground stationary tank used to store a class 2.1.1 low pressure liquefiable gas must be designed, constructed, and installed in accordance with—

(a) section 3.3 and section 3.5 of AS/NZS1596; or

(b) a code of practice approved by the Authority under section 79 of the Act relating to the safety of below ground stationary tanks that specifies requirements equivalent to the requirements specified in subparagraph (a).

Pressure management

38 Design, construction, installation, and operation of below ground stationary tank for gases for pressure management

Every below ground stationary tank used to store gases must be designed, constructed, installed, and operated to ensure that the pressure or vacuum resulting from filling or emptying the tanks will not cause either of the following:

(a) stress in excess of the maximum design stress of the tank:

(b) the tank to collapse.
