Division 5 METHODS FOR DETERMINING ANNUAL QUANTITIES OF MATERIALS AND FUELS

Where the operator has to determine annual quantities of fuels or materials, including products relating to product benchmark sub-installations, the operator shall determine such quantities at installation level or for each relevant sub-installation, as required, in one of the following ways:

1. (a)

   based on continual metering at the process where the material is consumed or produced;

2. (b)

   based on aggregation of metering of quantities separately delivered or produced taking into account relevant stock changes.

For the purposes of point (b) of the first paragraph, the quantity of fuel or material consumed during the calendar year at the installation or sub-installation shall be calculated as the quantity of fuel or material imported during the calendar year, minus the quantity of fuel or material exported, plus the quantity of fuel or material in stock at the beginning of the calendar year, minus the quantity of fuel or material in stock at the end of the calendar year.

For the purposes of point (b) of the first paragraph, the quantity of product or other material exported during the calendar year shall be calculated as the quantity of product or material exported during the reporting period, minus the quantity imported or recycled into the process, minus the quantity of product or material in stock at the beginning of the calendar year, plus the quantity of product or material in stock at the end of the calendar year.

Where it is technically not feasible or would incur unreasonable costs to determine quantities in stock by direct measurement, the operator may estimate those quantities based on one of the following:

1. (a)

   data from previous years and correlated with appropriate activity levels for the reporting period;

2. (b)

   documented procedures and respective data in audited financial statements for the reporting period.

Where the determination of quantities of products, materials or fuels for the entire calendar year is technically not feasible or would incur unreasonable costs, the operator may choose the next most appropriate day to separate a reporting year from the following one, and reconcile accordingly to the calendar year required. The deviations involved for one or more product, material or fuel shall be clearly recorded, form the basis of a value representative for the calendar year, and be considered consistently in relation to the next year.
