Description: The Prince William Sound Regional Citizens’ Advisory Council (RCAC) is concerned whether or not petroleum hydrocarbons from the ballast water treatment facility (BWTF) of the Alyeska Pipeline Service Company’s Valdez Marine Terminal are present in the water column outside the National Pollutant Discharge Elimination System (NPDES) permit mixing zone. If they are present, to what extent and have they exceeded the limits that are recognized to have harmful effects on marine organisms. Michael Salazar and Sandra Salazar (Applied Biomonitoring), Jeffrey Short (National Oceanographic and Atmospheric Administration (NOAA) Auke Bay Lab), and James Payne (Payne Environmental Consultants, Inc.) conducted an integrated monitoring study in the winter/spring of 2001 to address these concerns. The study was based on three state-of-the-art sampling methodologies: caged mussels, plastic membrane devices (PMDs), and large-volume water samples (LVWSs). Chemical fingerprinting was used to identify the source of detected hydrocarbons. The main goal of the study was to obtain sufficient data to allow RCAC to formulate substantive recommendations for testing requirements for the NPDES permit to be issued in 2002.
