Three Phases of Shoreline Clean-up

SAN FRANCISCO – As clean up phases progress in the Cosco Busan incident, they are categorized into three phases. Through these three phases, the Unified Command has established standards for oil clean-up throughout the Bay Area.

  • The gross oil removal phase: This phase consists of the removal of oil that is easily remobilized, or that is easily collected for proper disposal. Gross oil can be seen with the naked eye. In this phase, all substantial amounts of oil, mobile or pooled, are removed from the beach.
  • The Treatment phase: This phase involves the reduction of oil amounts to an acceptable level so that operations may continue at other locations. The recommended standard at high use public beaches is that there should be no visible oil.
  • The Maintenance phase: This phase is the final phase of clean-up operations. The area is inspected by an interagency team to confirm the area meets the clean-up standards. The end points are decided on a segment-by-segment bases level. This step requires completion of clean-up to a degree that is acceptable to the Unified Command and the community.

The decision to open a beach is the decision of the local trustee for that area. This is determined after a collaborative effort by the Unified Command and local authorities, if the treatment phase is complete.
