Division 2—Gas supply, quality etc 38—Obligations of distribution system operator and other persons in relation to quality of gas (1) A distribution system operator must ensure that the following requirements are complied with in relation to gas distributed by the system: (a) the gas must— (i) be at a safe temperature and pressure and safe in all other respects for the purposes of the system; and (ii) contain sufficient odorant that it has a distinctive smell to a person with a normal sense of smell at one‑fifth of the lower explosive limit in air; and (iii) comply with the relevant specifications set out in Schedule 2 (unless otherwise agreed between the Technical Regulator and the operator); (b) before connection or reconnection of a gas supply to a place, steps must be taken to ensure that the gas supply is suitable for each gas installation situated in the place that will be connected to the gas supply; (c) the gas must be supplied so that— (i) the operating pressure of the gas at the outlet of each meter set for recording a customer's consumption of gas is 1 kPa or more but less than 3 kPa subject to any written requirement of the customer or agreement between the Technical Regulator and the operator for gas to be supplied at more than 3 kPa; and (ii) the pressure of the gas at each such meter set is within the meter set manufacturer's designated pressure operating range. (2) After a gas installation referred to in subregulation (1)(b) has been connected (including for the first time), reconnected or a person has carried out work on such an installation, the person who performed the connection, reconnection or carried out the work must issue an electronic certificate of compliance to the effect that the requirement in subregulation (1)(b) has been complied with. (3) The person must— (a) provide a copy of the completed electronic certificate of compliance to the person on whose behalf the work was carried out; and (b) provide a copy of the completed electronic certificate of compliance to the distribution system operator. (4) For the purposes of ensuring compliance with subregulation (1)(b), reliance may be placed on an electronic certificate of compliance issued for the purposes of section 56 of the Act in relation to the gas installation. (5) Despite regulation 7(4), a person who operates a prescribed transmission pipeline is not bound to comply with subregulation (1)(a)(ii). (6) However, a person who receives a gas supply directly from a transmission pipeline (if the gas supplied does not already contain sufficient odorant for the purposes of that subregulation) must comply with subregulation (1)(a)(ii). (7) If a gas installation is reconnected following disconnection as a result of a change of customer or on the basis of a failure to pay for the gas supplied to premises at which the installation is located, the person who performs the reconnection is exempt from any requirement under this Part to issue an electronic certificate of compliance in respect of the reconnection. (8) If, in respect of premises, a person installs or replaces a meter for recording consumption of gas (and performs no other work to which Division 1, Division 2 or Division 3 applies), the person is exempt from any requirement under this Part to issue an electronic certificate of compliance in respect of the installation or replacement of the meter. 39—Obligations of retailer in relation to supply of gas A retailer must ensure that the following requirements are complied with in relation to gas supplied by the retailer to a customer: (a) before connection or reconnection of a gas supply to a place, steps must be taken to ensure that the gas supply is suitable for each gas installation situated in the place that will be connected to the gas supply; (b) the heating value of the gas must, when measured at each measuring point approved by the Technical Regulator for that purpose, be within a margin of plus or minus 1% of the claimed heating value used by the gas entity as the basis for its charges to the customer for the gas; (c) the measured heating value of the gas must not show systematic bias within that margin. 40—Quality of liquefied petroleum gas supplied in pressurised vessel A person must not sell liquefied petroleum gas knowing, or in circumstances in which the person ought reasonably to know, that it is likely to be supplied to gas appliances from a pressurised vessel unless it complies with the relevant specifications set out in Schedule 2.
