(2014 formatting changes)

Authorship and Acknowledgements
The principal organizer and compiler of the 2008 report was Ellen Faurot-Daniels (CCC), with critical conceptual input and resource information support provided by Yvonne Addassi (OSPR). Creating the 2008 draft California Dispersant Plan would not have proceeded smoothly or successfully without the contributions of thought, effort and review provided by many others.
We relied extensively on work already completed by other authors and institutions. Leigh Stevens of Cawthron Institute, New Zealand, led the way by allowing us to use his “Oil Spill Dispersants: Guidelines for Use in New Zealand” as an extremely helpful model for our document. We also drew from various dispersant guidelines provided by Regional Response Teams throughout the U.S., dispersant guidelines published by ExxonMobil, the Cutter Information Corporation’s “Oil Spill Dispersants: From Technology to Policy”, the “Assessment of the Use of Dispersants on Oil Spills in California Marine Waters” by S.L. Ross, and various oil spill job aids available from the NOAA web site. Please see the References Cited section in this document for the full citations.
Beyond the use of these reports was the steadfast assistance of those we worked with in our own agencies and those on the Los Angeles Area Committee, dispersant subcommittee, dispersant workgroups, and various interested parties watching and assisting from outside the immediate working groups. Randy Imai of OSPR provided the charts in this report, Al Allen (Spilltec) provided the information, figures and formulas for dispersant dosage rates and relating those rates to dispersant application systems, and the oil spill clean-up cooperatives in California provided updated information on dispersant application resources. Members of the Los Angeles workgroups reviewed early drafts of this document, with John Day (Santa Barbara County) and Craig Ogawa (Minerals Management Service) providing especially helpful comments along the way. Ben Waltenberger (NOAA), Ken Wilson (OSPR), Melissa Boggs-Blalack (OSPR) and Ellen Faurot-Daniels (CCC) pitched in to draft the Wildlife Aerial Observation Protocols, and Melissa Boggs-Blalack led the workgroup addressing public outreach.
We also extend particularly heartfelt thanks our colleagues in our own agencies who supported our efforts all along the way, and to the members of the Regional IX Regional Response Team and the U.S. Coast Guard who had the first vision of a California Dispersant Plan.
