APPLIED PRODUCTS

BACKGROUND

Alaska Marine Lines and its sister company, Northland Services, provide marine freight transportation from Seattle, Washington to and from Alaska, Prince William Sound, Hawaii and the Yukon Territory of Canada. The 70-acre Terminal 115 facility in Seattle handles 750,000 tons of goods annually, making it one of the West Coast’s largest barge terminals.

In 2011, Alaska Marine Lines initiated a program to retrofit its facilities with stormwater treatment to remove copper, zinc and turbidity from runoff. To date, Alaska Marine Lines has retrofitted four of its yards with Aquip® enhanced stormwater filtration systems including three Aquip 210SBE’s, an Aquip 160SBE, an Aquip 110SBE and three Aquip 12TXEs totaling nearly 1,000 gpm of treatment capacity. In 2015, the industrial general permit was modified to include an effluent limit for total suspended solids for discharge to a 303(d)-listed water.

As a result of Alaska Marine Line’s stormwater improvements and the StormwateRx treatment systems, the Alaska Marine Lines facilities that have had Aquip installed for more than two years are in full compliance and have been able to qualify for consistent attainment.
