OAR 340-142-0070: Approval Required for Use of Chemicals

(1) Use of any material on water to coagulate oil spills, treat oil spills, or disperse oil spills, must be specifically approved by the Department in advance of such use. (2) Physical removal of oil, and any materials added to the environment during the spill response, will ordinarily be required unless the Department determines the use of chemical dispersants is warranted by extreme fire danger or other unusually hazardous circumstances. (3) Use of surfactants and treatments to remove oil spill contamination from marine structures and vessels is limited to those materials approved by the Department during a response. (4) Fire suppressant materials must be used in accordance with the manufacturer’s instructions.
