Why We're Green

Maxum operates two fuel docks, a fleet of tank trucks, and a fleet of tank vessels within the State of Washington. In the previous 10 years we’ve conducted over 30 thousand over the water oil transfers in the state, far more than any other company, while transferring almost 650 million gallons of clean fuel and lubricant. During these transfers Maxum has not spilled one drop of oil to water. We work closely with the U.S. Coast Guard, Department of Ecology, and the EPA to continually improve upon our safe, clean, and compliant operations.
Maxum also is a leader in stormwater management. All stormwater from our facility is captured and treated, which gives us some of the very cleanest water in the city. We've partnered with the Port of Seattle to provide their tenants with green fueling options that eliminate stormwater impacts, reduce spill risk, lower greenhouse gas emissions, while taking vehicles off the road. We share our rain management strategy by annually hosting ECOSS's stormwater workshops, working with consultants in presentations at NEBC conferences, and have been featured in Stormwater Solutions Magazine.


At Maxum we believe that the best way to ever improve upon our safe, clean, and compliant operations is to have them be sustainable. The best way for them to be sustainable is for them to be profitable. We believe in the win-win-win. A win for the environment, a win for the community, and a win for our business.
