Mikkel Foltmar, one of the newest additions to the council’s volunteer roster, is almost as new to Alaska as he is to the council. However, he hasn’t wasted time putting his knowledge and experience to work to help protect the waters of Prince William Sound.

In 2012, Alyeska identified a 6 inch wide area of external corrosion on crude oil piping near the end of one of their oil-loading berths, known as Berth 5, at the Valdez Marine Terminal. Corrosion in the 48 inch diameter pipe is of particular concern, as it is located over water.
On July 10, staffer Nelli Vanderburg visited the terminal to observe an inspection and repairs to drainage piping under the secondary containment liner. These pipes drain water from the secondary containment area after a rain. A manhole was also being installed.
While the pipes were being repaired, Alyeska took the opportunity to inspect and test the secondary containment liner. The liner is made of “catalytically blown asphalt,” or asphalt that has been blown into place, as opposed to poured. In the photo below, a section of the flexible liner is being cut. The cut section will be tested for permeability. The last inspection and testing of these liners was in 1992.
A recent council study looked at issues associated with the remote control operations of Alyeska Pipeline Service Company’s Valdez Marine Terminal. Alyeska controls some operations for the terminal and pipeline from its Operational Control Center in Anchorage.
