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.
Aspect assisted a concrete pole manufacturer in planning and implementing a new stormwater treatment system to comply with the requirements of Ecology’s ISGP. We evaluated stormwater infrastructure upgrades and treatment options, and identified actions for achieving cost effective, long-term compliance with Industrial Stormwater General Permit (ISGP) requirements. The new stormwater management system features StormwateRx’s Aquip Enhanced Stormwater Filtration System, downspout media filters, and catch basin insert filters. Initial water quality monitoring results indicate all ISGP water quality benchmarks were easily achieved.
