Ameron Industrial Stormwater General Permit (ISGP) Support

Aspect is assisting a concrete pole manufacturer complete stormwater infrastructure improvements to comply with their ISGP. The facility is on a Port of Everett brownfield undergoing MTCA cleanup. We developed, coordinated, and implemented a strategy to fast-track remediation of overlying contaminated soils to facilitate replacement of their storm drainage pipes. Our approach resulted in faster removal of 2,000 cubic yards of contaminated soil, improved ISGP compliance, better site drainage, and lower construction cost by separating the work from the RI/FS process. Our involvement in both the remediation and stormwater work allows adaptation of the project to changing conditions.
