19 Calculating pool averages

(1)

The pool averages specified in Schedule 1 for the purpose of the total aromatic compounds limit for petrol must be determined as set out in this regulation.

(2)

Pool averages must be calculated separately by each producer of petrol in New Zealand and by each petrol importer.

(3)

Monthly pool averages must be calculated based on,—

(a)

for petrol produced in New Zealand, batch fuel quality, as indicated on the certificate of quality, and quantity and date of completion of loading, as indicated on the bill of lading; and

(b)

for imported petrol, batch fuel quality, as indicated on the certificate of quality, and supplied quantity and date of completion of discharge into the first port storage at a New Zealand port, as indicated on the bill of lading or other appropriate documentation.

(4)

Each producer of petrol in New Zealand and each petrol importer must keep, for a period of not less than 3 years, records of the following with regard to total aromatic compounds that are regulated by pool averaging:

(a)

the relevant fuel quality, for each individual batch; and

(b)

the quantity of each individual batch, on a mass or volume basis as appropriate; and

(c)

the date of the batch, being either the date of completion of loading as referred to in subclause (3)(a) or the date of completion of discharge as referred to in subclause (3)(b); and

(d)

the monthly average, as calculated under subclause (6)(a) and (b); and

(e)

the monthly journal entry, as calculated under subclause (6)(c).

(5)

Each producer of petrol and each petrol importer must provide access in New Zealand to the records required to be kept under subclause (4) when requested, in writing, to do so by the responsible Minister of the Crown.

(6)

For total aromatic compounds in petrol, for each calendar month during the period that this regulation is in force, each producer of petrol in New Zealand and each petrol importer must separately calculate the average percentage of total aromatic compounds for each relevant grade of petrol produced or imported in that month as follows:

(a)

for each batch of regular grade petrol and each batch of premium grade petrol respectively produced or imported in the month, the average total aromatic compounds content of the batch (in litres per litre) is multiplied by the volume of the batch (in litres) to obtain the volume of total aromatic compounds (in litres) contained in the batch; and

(b)

the volume of total aromatic compounds calculated from all petrol batches of the relevant grade produced or imported in a month is added together and the total divided by the total volume of all the month’s batches to produce the monthly average total aromatic compounds content (in litres per litre) as follows:

			n Σ(A_i × V_i) i = 1
monthly average =			n Σ(V_i) i = 1

where—

A_i: is the average total aromatic compounds content for batch i in litres per litre
V_i: is the volume of batch i in litres
n: is the total number of batches in the month; and

(c)

the monthly average total aromatic compounds content is subtracted from the pool average maximum expressed in litres per litre, and the difference multiplied by the total volume of all the month’s batches of the relevant grade to produce the monthly journal entry as follows:

monthly journal entry

(pool average maximum − monthly average)

n
Σ(V_i)
i = 1

where—

V_i: is the volume of batch i in litres
n: is the total number of batches in the month.

(7)

In any period of 6 consecutive months, the sum of the monthly journal entries must not be a negative number.

(8)

Engine Fuel Specifications Amendment Regulations 2017 (LI 2017/259)

Criminal Procedure (Consequential Amendments) Regulations 2013 (SR 2013/409): regulation 3(2)

¹For regular and premium grade petrol in summer, a minimum E70 of 20% is permitted. Petrol that complies with the previous season’s quality, and that is stored in a filling-station tank to which fewer than 3 deliveries of petrol have been made since 6 weeks before the beginning of the season, is regarded as complying with this specification for up to 6 weeks after the beginning of the season.

²For regular and premium grade petrol blended with more than 1% volume oxygenates, the E70 maximum is increased by 1% per 1% volume oxygenates in the blend.

³For regular and premium grade petrol blended with more than 1% volume oxygenates, the flexible volatility index maximum allowed is 115.0 summer; 120.0 autumn and spring; 130.0 winter. Petrol that complies with the previous season’s quality, and that is stored in a filling-station tank to which fewer than 3 deliveries of petrol have been made since 6 weeks before the beginning of the season, is regarded as complying with this specification for up to 6 weeks after the beginning of the season.

⁴For regular and premium grade petrol blended with more than 1% oxygenates, the maximum vapour pressure allowed is Auckland and Northland: 72 kPa summer, 87 kPa autumn and spring, 97 kPa winter; rest of North Island: 77 kPa summer, 87 kPa autumn and spring, 97 kPa winter; South Island: 82 kPa summer, 92 kPa autumn and spring, 102 kPa winter. Petrol that complies with the previous season’s quality, and that is stored in a filling-station tank to which fewer than 3 deliveries of petrol have been made since 6 weeks before the beginning of the season, is regarded as complying with this specification for up to 6 weeks after the beginning of the season.

⁵Regulation 8(3)(c) provides that ethanol must comply with Schedule 4 (requirements for denatured ethanol for blending).

⁶Regulation 10 provides that the fatty acid methyl esters (biodiesel) must comply with Schedule 3: Requirements for biodiesel.

⁷For diesel blended with more than 1% and not more than 7% volume biodiesel, the density maximum is 854 kg/m³.

⁸The cetane index is not applicable for diesel blended with biodiesel.

⁹These are maximum criteria; cold flow properties of a fuel must be fit for common purposes in the region and the season in which it is sold. Diesel that complies with the previous season’s quality, and that is stored in a filling-station tank to which fewer than 3 deliveries of diesel have been made since 6 weeks before the beginning of the season, is regarded as complying with this specification for up to 6 weeks after the beginning of the season. Sales for marine use may be summer grade at any time of the year.

¹⁰The limit for sulphur does not apply to sale for marine use. See also regulation 15(2).

¹¹Regulations 10(a) and 17(2)(a) provide that, in the case of the biodiesel component of any blend of diesel and biodiesel, the maximum viscosity at 40ºC is 6.0 mm² per second.

¹²Regulations 10(b) and 17(2)(b) provide that, in the case of the biodiesel component of any blend of diesel and biodiesel, the minimum cetane number is 47.

¹³Regulation 10(c) provides that, in the case of the biodiesel component of any blend of diesel and biodiesel sold by retail sale, the minimum oxidation stability is 10.0 hours.

¹⁴The denaturant contained in ethanol must comply with regulation 8(3)(b) in the case of retail sales and regulation 14(3)(a) in the case of non-retail sales.
