Other Data Collection Methods and Rationale

Volume of Chemical Substances Handled/Emitted

Class 3 and Class 4 chemical substances for which the amount handled annually is 100kg(Class3)/1,000kg(Class4) or more are subject to reporting.

• The volume of chemical substances handled represents the volume of chemical substances used at sites; purchase volume is substituted when exact volume of usage cannot be determined.
• Volume of chemical substances released from sites in relation to their operation; calculations are based on purchase volume x distribution coefficient.

Emissions of Water Pollutants (BOD, COD)

Concentrations in water emitted x volume of water emitted. Sites that are requested by law and/or by other demands such as contracts are subjected to this data collection.

Emissions of Air Pollutants (NOx, SOx)

Volume calculated by multiplying emission volume by emission concentration. Sites that are requested by law and/or by other demands such as contracts are subjected to this data collection.
