Chapter I

GENERAL PROVISIONS

Article 1. Scope

This Circular prescribes list of dispersants permitted for use within Vietnamese waters and guidelines for using dispersants in response to oil spill incidents at sea.

Article 2. Regulated entities

This Circular applies to domestic and international agencies, organizations and individuals conducting activities which involve the use of dispersants in response to oil spill incidents in Vietnamese waters.

Article 3. Term interpretation

1. “dispersant” refers to a compound chemical substance employed to break the surface structure of oil trails into small oil trails, break and disperse oil into water columns in form of tiny droplets.

...

...

...

3. “oil dispersion efficiency” refers to dispersion capacity of dispersants for a type of oil in experiment conditions.

4. "EC50 72h (Effective Concentration)” refers to concentration of a substance which reduces growth rate of Skeletonema Costatum algae by 50% after 72 hours of interacting with the substance.

5. “LC50 96h (Lethal Concentration)” refers to concentration of a substance which eliminate 50% of Penaeus Monodon shrimp larva after 96 hours of interacting with the substance.

6. “flash point” refers to the lowest temperature in air pressure condition at which the sample ignites with an appearance of fire and spreads rapidly across the sample’s surface.

7. “aerobic decomposition capacity after 28 days of experiment” refers to level of decomposition of organic matter in an aerobic condition caused by natural microorganisms which exist in seawater environment after 28 days of experiment.

...

...

...

2. Determine amount of dispersants necessary.

3. Spray or spread dispersants to respond to oil spill incidents.

4. Monitor oil dispersion efficiency while spraying or spreading dispersants.

5. Monitor environment quality after employing dispersants.

6. Produce reports after employing dispersants.

Article 6. Regulate the use of dispersants in response to oil spill incidents within Vietnamese waters

Entities, organizations and individuals employing dispersants in response to oil spill incidents within Vietnamese waters must satisfy following regulations:

1. Complying with Article 5 of Law on Chemicals and Clauses 1, 2, 3, and 4 Article 24 of Regulations on responding to oil spill incidents attached to Decision No. 02/2013/QD-TTg dated January 14, 2013 of Prime Minister.

2. Employing dispersants only within the first 72 hours after the oil has spilled; refraining from employing dispersants if the majority of spilled oil has been weathered or dispersed naturally.

...
