    2020-03-03· In any particular situation, the decision to use dispersants involves balancing the potential advantages of dispersant use--removing oil from the water surface and avoiding some shoreline impacts--with the potential disadvantages, such as impacts to plankton or other water column organisms.

    Given that the use of dispersants does not remove oil from the environment, dispersant use is only considered when the answer to this question is “no,” which then leads decisionmakers to evaluate the appropriateness of dispersant use. Although a subset of factors that may limit the effectiveness of mechanical response are readily evaluated (e.g., spill occurs too far from shore to allow
