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

• ne‐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

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

ATC’s Support for Ballast Water (BW) Treatment Research 1999‐2003: Initial prototype Nutech‐O3 ozonation system installed and tested onboard TONSINA. Cost 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

• rganism sizes tested with the

exception of the amphipods (GT 50 microns.) Continued testing recommended.

ATC has continually supported the effort to find and develop new ballast water treatment technology:

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

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.

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.

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

• n 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.

ATC’s Current Evaluation of Potential BWMSs

To identify a compliant system ATC has been evaluating potential

• BWMSs. The following manufactures have been considered:

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 .

The following manufacturers are still being considered, however, neither have received system USCG Type Approval, nor have demonstrated that they can comply with the California interim BW discharge performance standards: The following manufacturers are still being considered, however, neither have received system USCG Type Approval, nor have demonstrated that they can comply with the California interim BW discharge performance standards:

Oceansaver

• Advantages:

‐ Manufacturer has applied for USCG Type Approval. ‐ Meets capacity. ‐ Can treat at low dosage levels of chlorine which does not harm protective coatings. ‐ Does not require the carriage or use of any chemicals.

Severn Trent’s BalPure

• Advantages:

‐ Manufacturer has applied for USCG Type Approval. ‐ Meets capacity.

• Disadvantages:

‐ High chorine levels may effect tank coatings. ‐ Requires the carriage and addition of sodium bisulfate for neutralization of treated BW prior to discharge.

The USCG expects the first BWMS to receive Type Approval in Summer,

• 2016. This will not be a UV system. (Maritime Executive, 12/23/15)
• Currently manufacturers have filed 30 letters of intent with the USCG, expressing their

intention to start testing a ballast water treatment system. The Coast Guard estimates about half that number are presently at some stage of testing with one of the five approved independent labs.

• Independent labs have indicated that the test facilities are booked through the end of

2015 and for most of 2016

The USCG announced on 12/14/15 that the Most Probable Number methodology of testing UV systems is not considered an equivalent alternative to the testing method prescribed in the USCG regulations for Type Approval of BWMSs.

• As a result of this decision, as reported by Maritime Executive, the industry

foresees a delay when the Coast Guard will conclude on the first type approval of any BWMSs.

This means currently are no systems available for purchase, and there still may not be by the summer of 2017 when needed for AK Frontier. This means currently are no systems available for purchase, and there still may not be by the summer of 2017 when needed for AK Frontier.

The USCG and BWMS manufacturers need more time to continue assessing systems in

• rder to achieve system USCG Type Approval.

ATC needs more time to continue to search for a system that reports they can meet the CA BW discharge performance standards.

It is imperative that ATC have a BWMS that is proven and operationally tested. It is imperative that ATC have a BWMS that is proven and operationally tested.

ATC’s Mission of safe, reliable transport of 1/3rd of Alaska’s oil helps protect

• ur shared environment and generates over 30% of Alaskan tax revenues

1 in every 10 bbls of oil shipped into both Washington and California is on ATC ships This mantle of responsibility compels us to be careful and conservative in

• ur selection & installation of BWMSs.
