year, one of the following approaches must be used:
 (a) the survey approach mentioned in subsection (2C);
 (b) the error allowance approach mentioned in subsection (2D).
 (2A) The approach selected must be consistent with the principles mentioned in section 1.13.
 (2B) The same approach, once selected, must be used for the facility for each year unless:
 (a) there has been a material change in the management of the stockpile during the year; and
 (b) the change in the management of the stockpile results in the approach selected being less accurate than the alternative approach.
  (2C) The survey approach is as follows:

           Step 1. Estimate the quantity of solid fuel in the stockpile by:

                (a) working out the volume of the solid fuel in the stockpile using aerial or general survey in accordance with industry practice; and
                (b) measuring the bulk density of the stockpile in accordance with subregulation (3).

           Step 2. Replace the current book quantity with the quantity estimated under step 1.
           Step 3. Maintain the book quantity replaced under step 2 by:

                (a) adding deliveries made during the year, using:
                 (i) invoices received for solid fuel delivered to the facility; or
                 (ii) solid fuel sampling and measurements provided by  measuring equipment calibrated to a measurement               requirement; and
                (b) deducting from the amount calculated under paragraph (a), solid fuel consumed by the facility.

           Step 4. Use the book quantity maintained under step 3 to estimate the change in the quantity of the stockpile of the fuel.
 (2D) The error allowance approach is as follows:

           Step 1. Estimate the quantity of the stockpile by:

                (a) working out the volume of the solid fuel in the stockpile using aerial or general survey in accordance with industry practice; and
                (b) measuring the bulk density of the stockpile in accordance with subregulation (3).

           Step 2. Estimate an error tolerance for the quantity of solid fuel in the stockpile. The error tolerance is an estimate of the uncertainty of the quantity of solid fuel in the stockpile and must be:

                (a) based on stockpile management practices at the facility and the uncertainty associated with the energy content and proportion of carbon in the solid fuel; and
                (b) consistent with the general principles in section 1.13; and
                (c) not more than 6% of the estimated value of the solid fuel in the stockpile worked out under step 1.

           Step 3. Work out the percentage difference between the current book quantity and the quantity of solid fuel in the stockpile estimated under step 1.
           Step 4. If the percentage difference worked out under step 3 is within the error tolerance worked out under step 2, use the book quantity to estimate the change in the quantity
