Division 4

BAT is to prevent, or where that is not practicable, to reduce diffuse gaseous emissions from the storage and handling of volatile raw materials by using one or a combination of the following techniques:

1. (i)

   Use of tank paint with low solar absorbency for bulk storage subject to temperature changes due to solar heating.

2. (ii)

   Control of temperature in the storage of volatile raw materials.

3. (iii)

   Tank insulation in the storage of volatile raw materials.

4. (iv)

   Inventory management

5. (v)

   Use of floating roof tanks in the storage of large quantities of volatile petroleum products.

6. (vi)

   Use of vapour return transfer systems in the transfer of volatile fluids (e.g. from tank trucks to storage tank).

7. (vii)

   Use of bladder roof tanks in the storage of liquid raw materials.

8. (viii)

   Use of pressure/vacuum valves in tanks designed to withstand pressure fluctuations.

9. (ix)

   Application of a release treatment (e.g. adsorption, absorption, condensation) in the storage of hazardous materials.

10. (x)

    Application of subsurface filling in the storage of liquids that tend to foam.
