facility that is constituted by an activity that is petrochemical production:
 (a) method 1 under section 2.61;
 (b) method 2 under section 2.62;
 (c) method 3 under section 2.63;
 (d) method 4 under Part 1.3.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

2.61  Method 1—petrochemical production
  Method 1, based on a carbon mass balance approach, is:

Step 1  Calculate the carbon content in all fuel types (i) delivered for the activity during the year as follows:
        where:
        i means sum the carbon content values obtained for all fuel types (i).
        CCFi is the carbon content factor measured in tonnes of carbon for each tonne of fuel type (i) as mentioned in Schedule 3 consumed in the operation of the activity.
        Qi is the quantity of fuel type (i) delivered for the activity during the year measured in tonnes and estimated in accordance with criterion A in Divisions 2.2.5, 2.3.6 and 2.4.6.
Step 2  Calculate the carbon content in products (p) leaving the activity during the year as follows:
        where:
        p means sum the carbon content values obtained for all product types (p).
        CCFp is the carbon content factor measured in tonnes of carbon for each tonne of product (p).
        Ap is the quantity of products produced (p) leaving the activity during the year measured in tonnes.
Step3   Calculate the carbon content in waste by‑products (r) leaving the activity, other than as an emission of greenhouse gas, during the year as follows:

        where:
        r means sum the carbon content values obtained for all waste by‑product types (r).
        CCFr is the carbon content factor measured in tonnes of carbon for each tonne of waste by‑product (r).
        Yr is the quantity of waste by‑product (r) leaving the activity during the year measured in tonnes.
Step 4  Calculate the carbon content in the amount of the increase in stocks of inputs, products and waste by‑products held within the boundary of the activity during the year as follows:
        where:
        i has the same meaning as in step 1.
        CCFi has the same meaning as in step 1.
        ΔSqi is the increase in stocks of fuel type (i) for the activity and held within the boundary of the activity during the year measured in tonnes.
        p has the same meaning as in step 2.
        CCFp has the same meaning as in step 2.
        ΔSap is the increase in stocks of products produced (p) by the activity and held within the boundary of the activity during the year measured in tonnes.
        r has the same meaning as in step 3.
        CCFr has the same meaning as in step 3.
        ΔSyr is the increase in stocks
