Project Summary

Vigor Industrial LLC (Vigor) operates a 65-acre shipyard in Portland, Oregon, offering full-service vessel repair, maintenance, and new construction, as well as complex fabrication of bridge and aerospace components and steel structures.

Facility operations require coverage under a NPDES 1200-Z General Permit for discharge of stormwater to the Willamette River. The facility sits within the Portland Harbor Superfund Site, and Vigor has entered into a Consent Order with the Oregon Department of Environmental Quality (ODEQ) for implementation of stormwater source control measures. Vigor has completed numerous stormwater improvements across the facility, including implementation of both Tier II Corrective Actions under the facility’s 1200-Z Permit and contingency source control measures under the Consent Order.

Our Approach

Floyd|Snider began supporting the Portland facility in 2017 and provides site planning and stormwater management support to Vigor through engagement with the City of Portland for compliance with the facility’s 1200-Z Permit and with ODEQ for regulatory compliance and source control under the Consent Order.

Floyd|Snider leads the project team to build consensus among the regulatory agencies, conduct in-depth evaluation of stormwater source control and treatment technologies, and has developed a phased approach to stormwater improvements at an active shipyard. The approach maximizes use of existing infrastructure and stormwater treatment facilities to minimize the extent of valuable shipyard real estate taken up by stormwater improvements across the 65-acre facility. Stormwater treatment includes both small-scale passive stormwater treatment and large-scale detention and active treatment in an electrocoagulation (EC) system.

Project Milestones

2017–2021. Initial stormwater source control measures
2021. 1200-Z stormwater treatment improvements
2022. Completion of Phase 1 to reroute additional 11.7 acres to the EC system
2024. Completion of Phase 2 to reroute additional 9.8 acres to the EC system
