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 of the stockpile of the fuel.
           Step 5. If the percentage difference worked out in step 3 is more than the error tolerance worked out in step 2:

                (a) adjust the book quantity by the difference between the percentage worked out under step 3 and the error tolerance worked out under step 2; and
                (b) use the book quantity adjusted under paragraph (a) to estimate the change in the quantity of the stockpile of the fuel.
 (3) The bulk density of the stockpile must be measured in accordance with:
 (a) the procedure in ASTM D/6347/D 6347M‑99; or
 (b) the following procedure:

           Step 1 If the mass of the stockpile:

                (a) does not exceed 10% of the annual solid fuel combustion from the operation of a facility—extract a sample from the stockpile using a mechanical auger in accordance with ASTM D 4916‑89; or
                (b) exceeds 10% of the annual solid fuel combustion — extract a sample from the stockpile by coring.

           Step 2 Weigh the mass of the sample extracted.
           Step 3 Measure the volume of the hole from which the sample has been extracted.
           Step 4 Divide the mass obtained in step 2 by the volume measured in step 3.

 (4) Quantities of solid fuel delivered for the facility must be evidenced by invoices issued by the vendor of the fuel.
 (5) In this section:
book quantity means the quantity recorded and maintained by the facility operator as the quantity of solid fuel in the stockpile.

2.16  Direct measurement at point of consumption—criterion AAA
 (1) For paragraph 2.14(2)(c), criterion AAA is the measurement during a year of the solid fuel combusted from the operation of the facility.
 (2) The measurement must be carried out either:
 (a) at the point of combustion using measuring equipment calibrated to a measurement requirement; or
 (b) at the point of sale using measuring equipment calibrated to a measurement requirement.
 (3) Paragraph (2)(b) only applies if:
 (a) the change in the stockpile of the fuel for the facility for the year is less than 1% of total combustion on average for the facility during the year; and
 (b) the stockpile of the fuel for the facility at the beginning of the year is less than 5% of total combustion for the year.

2.17  Simplified consumption measurements—criterion BBB
  For paragraph 2.14(d), criterion BBB is the estimation of the solid fuel combusted during a year from the operation of the facility in accordance with industry practice if the
