Alaska Tanker Company Prince William Sound Regional Citizens Advisory Council January, 2016
Dear Anil and all Alaska Tanker Company Staff, Congratulations on completing 20 million man‐hours with only one lost time injury and spilling no oil to sea. For the last 14 years, Alaska Tanker Company has exemplified the working relationship we all strive for – keeping our economy going in the absolute safest way possible. This unprecedented accomplishment would not have been achieved without the hard work and dedication of everyone at ATC. Your commitment to each other, through teamwork, is a commitment to the entire west coast of the United States and Canada. While your ships have quietly carried one‐third of Alaska North Slope crude oil along our shores, the accolades from us living in those areas have, at times, been just as quiet. However please know, that we recognize all the effort put forth to achieve this world‐class milestone and sincerely thank each and every one of you. Best wishes and continued safety, Amanda Bauer President Prince William Sound Regional Citizens Advisory Council
Alaska Tanker Company ATC’s Ballast Water Management Program Agenda 1) What ATC has done to support Ballast Water research 2) Summary of IMO and USCG requirements ‐ Application to ATC’s fleet ‐ What actions ATC has taken to assess system availability 3) Projected view of Ballast Water ‐ Status of the USCG Type Approval of the Ballast Water Management Systems (BWMS) available 4) Why it is important for ATC to have a system that’s proven 2
Alaska Tanker Company ATC’s Support for Ballast Water (BW) Treatment Research ATC has continually supported the effort to find and develop new ballast water treatment technology: 1999 ‐ 2003: Initial prototype Nutech ‐ O3 ozonation system installed and tested onboard TONSINA. C ost for system installation was over $3 million, including 11 miles of ozone piping in the BW tanks. Research lead by Dr. Russell Herwig of University of Washington Results were successful for all organism sizes tested with the exception of the amphipods (GT 50 microns.) Continued testing recommended. 3

Alaska Tanker Company ATC’s Support for Ballast Water Treatment Research 2005 ‐ 2008: Second prototype Nutech ‐ O3 ozonation system installed and tested onboard PRINCE WILLIAM SOUND . Cost for system installation was over $1 million. Research performed by David A. Wright, Univ. of MD Center for Environmental Science. Results show the ability to meet the IMO standards for all organism sizes with the exception of nematodes (10 ‐ 50 micron range.) Further testing recommended. Hawaii 5
Alaska Tanker Company ATC’s Support for Ballast Water Treatment Research 2008: ALAKSAN NAVIGATOR provided the platform for Smithsonian Environmental Research Center (SERC) testing in October 2008. Research was performed to identify methods to verify BWE using the chemical constituents in seawater (tracers) to distinguish water that originates in ports (bays and estuaries) from open ocean water.

Alaska Tanker Company ATC’s Support for Ballast Water Treatment Research 2012: All four ATC ships have had their ballast water tested at least once, with 2 ships tested twice, this summer while in port in Valdez, AK. The Smithsonian Environmental Research Center’s (SERC) objective for this study is to characterize the biology of ballast water to assess propagule delivery during approximately 20 voyages into Valdez, and into the Chesapeake Bay.

Alaska Tanker Company ATC’s Ballast Water Management Practices ATCs’ Current Ballast Water (BW) Management Practice: Since the implementation of the NPDES VGP, ATC has been performing full exchanges on all ballast water tanks when the ships are at sea. These include: Full flow ‐ through exchange on ballast tanks in the cargo block. Complete empty/refill exchanges on all other ballast tanks. Regular use of Mud ‐ Out when loading in coastal waters. 8

Alaska Tanker Company ATC’s Current Evaluation of Potential BWMSs To install a BWMS by 8/4/18, ATC will need to: Order long lead items by November 2016. Identify USCG Type approved, and vessel compliant system. Begin purchasing these systems in summer of 2017 to able to meet AK FRONTIER’s next scheduled dry ‐ dock in the summer of 2018 . To identify a compliant system ATC has been evaluating potential BWMSs. The following manufactures have been considered: 11
