Reduction in the Release of Volatile Organic Compounds (Storage and Loading of Volatile Petroleum Liquids) Regulations — 1
1 The method to calculate the total loading factor of a facility for the previous calendar year is as follows: (a) determine the highest vapour pressure and the highest benzene concentration of each volatile petroleum liquid loaded at the facility; (b) for each volatile petroleum liquid and each loading recipient referred to in column 1 of Table 3 to this section, calculate the loading factor in accordance with the formula V ÷ (F benz × F VP × F load × 25 000) where V is the volume of the volatile petroleum liquid loaded, as calculated in accordance with the method set out in paragraph (c), F benz is the value set out in column 2 of Table 1 to this section for the benzene concentration determined under paragraph (a), F VP is the value set out in column 2 of Table 2 to this section for the vapour pressure determined under paragraph (a), and F load is the value set out in column 2 of Table 3 to this section for the loading recipient referred to in column 1; (c) determine the volume of each volatile petroleum liquid, in standard m 3 , that was loaded without the use of a vapour control system during the previous calendar year, taking into account the following modifications, if applicable: (i) if no volatile petroleum liquid was loaded at the facility during the previous calendar year, the volume that is expected to be loaded during the current calendar year must be determined, (ii) if 30% or more of the total volume of liquids loaded with the loading rack was switch loaded without the use of a vapour control system, the volume of any liquid switch loaded without the use of a vapour control system must be counted as the loading of a volatile petroleum liquid with F benz equal to 2.4 and F VP equal to 2.8, (iii) if a loading rack was equipped with a vapour control system in accordance with section 42 during the previous or current calendar year, the volume of volatile petroleum liquid loaded with that loading rack is not included in the calculation of the volume, and (iv) in the case of an exceptional event referred to under subsection 16 (2), the volume loaded with the loading rack during the period in which the exceptional event caused the volume of volatile petroleum liquids loaded with the loading rack to increase may be replaced with the average volume loaded with that loading rack during the same period in the most recent year during which no such event occurred or, if data are not available for any such year, an estimate of the volume that would be loaded during the same period under normal operating conditions; and (d) calculate the sum of the loading factors calculated under paragraph (b), which constitutes the facility’s total loading factor.
