Maxum Petroleum Industrial Stormwater General Permit Support

Aspect assisted Maxum Petroleum in achieving ISGP compliance at its diesel fueling and petroleum fuel/lubricant shipping and receiving facility located on Harbor Island in Puget Sound, Washington. A systematic and cost-effective approach was used to evaluate stormwater infrastructure upgrades, and treatability testing was performed to select the optimum stormwater treatment system. The new system features pressurized filtration and adsorptive media filtration. Initial water quality monitoring results indicate all ISGP water quality benchmarks were easily achieved.
