application or legal issues surrounding
dispersants

How do Dispersants
Work?
A: Dispersant droplets containing
surfactants are sprayed onto the oil.
B: The solvent carries the surfactant into
the oil.
C: The surfactant molecules migrate to
the oil/water interface and reduce
surface tension, allowing
D: small oil droplets to break away from
the slick.
E: The droplets disperse by turbulent
mixing, leaving only sheen on the water
surface
Key Concept: You need modest sea energy
to “agitate” the oil/dispersant interface
to effect dispersion.

Advantages & Disadvantages of Using Dispersants
•
•
•
•
•
•
Some ADVANTAGES
Removing oil from the surface keeps it
from reaching shoreline
Is often the quickest response method
Can be used in strong currents and higher
sea states
Reduces possibility of sea bird and
mammal contamination
Inhibits formation of emulsions
Increases surface area of oil available for
natural degradation
•

•

•
•
Some DISADVANTAGES
May adversely affect some marine
organisms that would not otherwise be
reached by oil
If dispersion is not achieved, may
decrease the effectiveness of other
methods
Not effective on all types of oil under all
conditions
If used on shore, may increase
penetration of oil into sediments
Adds additional extraneous sub- stances
into the marine environment7
Limited time window for use

New Regulations Effective
• Effective 8-22-2011 The USCG “CAPS”** Regulations became
effective.
• What that means is more dispersant planes in more places for
quicker response times. Additional King Airs have been located
in the following locations.
– Salisbury, Maryland
– San Juan, Puerto Rico
– Concord, California
** caps= USCG Capability Limit on dispersants 33 CFR parts 154 and 155
