USE OF DISPERSANTS - U.S. National Response Team (NRT)

DISPERSANT APPLICATION PLATFORM CAPABILITY DECISIONMATRIX NOTESNOTES:(1) For relatively small spills and where transit distance is short. Platform has relativelyshort operational duration and spray capacity.(2) Most capable platform for large spills. Has high endurance and spray capacity. If aCoast Guard C-130 Hercules is used to support ADDS-Pack deployment, inaccordance with existing MOAs, a modification (removal of rails in cargo bay) to theaircraft setup will be necessary which would take 6 to 8 hours to complete. Thisdelay should be accounted for when considering aircraft availability.(3) Good platform for endurance. Spray capacity is less than half of Adds-Pack. Formedium to large spills.(4) Use for medium to large spills. Moderate endurance. Spray capacity is similar.(5) Use for medium to large spills. Moderate endurance. Spray capacity is similar.(6) Crop-duster type aircraft good for small to medium spills. Can be turned aroundquickly for repeated treatments of larger slicks. Spray nozzles should be calibratedspecifically for dispersant operations to obtain correct droplet size and spray pattern.(7) Crop-duster type aircraft good for small to medium spills. Can be turned aroundquickly for repeated treatments of larger slicks. Spray nozzles should be calibratedspecifically for dispersant operations to obtain correct droplet size and spray pattern.(8) High endurance and spray capacity, but has slow operational speed.(9) Small to medium slicks or surgical treatment of the slick’s leading edge. Slow speedand low spray capacity.(10) May be good for surgical treatment of the slick’s leading edge and thickest portionsof the slick. Calibration and delivery rate may be difficult to control.
