Project Summary

Vigor Industrial (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 has entered into a Consent Order with the Oregon Department of Environmental Quality (DEQ) for implementation of stormwater source control measures. Vigor has completed several stormwater improvements across the facility and is currently designing and implementing 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 Oregon DEQ 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 develop a phased approach for implementation of stormwater improvements at an active shipyard. The Floyd|Snider team looks to incorporate retrofits and utilize existing infrastructure to minimize the extent of valuable shipyard real estate taken up for stormwater improvements across the 65-acre facility. Floyd|Snider is in the process of implementing both small-scale passive stormwater treatment and large-scale conveyance and active treatment improvements at the facility.

Project Milestones:

2017–2021. Stormwater source control measures
2021. 1200-Z stormwater treatment improvements
