Cooperative Agreements with the State of Washington Department of Ecology (CR

(CR 827870 ) and an Inter-Agency Agreement with the National Marine Fisheries 
Service (DW 13938780). Additionally, cooperative efforts with the NOAA National 
Ocean Service were conducted under a General Collaborative Agreement (NOS #MOA- 
2005-003/6764, EPA #PW139221956-01-0). 
This study involved the participation of numerous representatives from a variety 
of federal, state, local, academic, and private institutions. Many individuals within EPA 
made important contributions to the study. Critical guidance and vision in establishing 
the overall NCA-West program was provided by Kevin Summers of Gulf Ecology 
Division. Tony Olsen of Western Ecology Division (WED), with technical support from 
staff of Computer Science Corporation, provided the sampling designs utilized for 
various aspects of the study. Lorraine Edmond of Region 10 and Terrence Fleming of 
the Region 9 Offices of EPA ably served as the regional liaisons with the state 
participants. Robert Ozretich of WED performed a detailed review of the database 
contents used for this analysis, and we additionally thank him for his extensive quality 
assurance review of this document. 
A major portion of the study area was sampled from the NOAA ship McARTHUR 
II on Cruise AR-03-01-NC, which consisted of three legs encompassing the period from 
June 1-26, 2003. All members of the three field crews (see list below) are commended 
for their high level of technical expertise, teamwork and dedication to getting the 
required sampling completed. In particular, the dedication of the Chief Scientists for 
each of the three legs is greatly appreciated. These were Sarah Wilson formerly with 
Washington Department of Ecology (Leg 1), Larry Caton with Oregon Department of 
Environmental Quality (Leg 2), and Rusty Fairey with Moss Landing Marine 
Laboratories (Leg 3). Special appreciation also is extended to the officers and crew of 
the NOAA ship McARTHUR II for the superb job performed. 
Sarah Wilson also was especially helpful in obtaining published and unpublished 
data on the location of cable crossings, hard bottom areas, and other hazards to the 
safe and successful conduct of field sampling. Dr. Chris Goldfinger of Oregon State 
University and Dr. Gary Greene of Moss Landing Marine Laboratories kindly supplied 
unpublished bottom type data that was of assistance in preparation of the maps for 
determining sample locations. 
Personnel of the Fisheries Resource Analysis and Monitoring (FRAM) Division of 
the Northwest Fisheries Science Center (NWFSC) of NOAA collected fish specimens as 
part of their western ground-fish surveys at stations that coincided with the NCA-WEST 
sampling area. These specimens supplemented the pool of samples available for 
tissue-contaminant analysis performed subsequently by EPA and state partners.
