Water Quality

The Port of Longview has a robust water quality management program that addresses protective, pro-active resource protection as well as functional best management practices for marine cargo handling. We encourage you to explore our water quality programs and return often as we continue to enhance and grow our program effectiveness.

Stormwater

Stormwater protects apply to both construction and industrial use phases of Port managed areas. We consistently meet or exceed state standards and take actions every year to further improve the water quality of stormwater leaving our systems. 

Industrial Wastewater

For some of our berths and work areas, we manage fully contained systems that are piped to our industrial wastewater pre-treatment facility. This facility has a series of physical and chemical treatments to ensure that our industrial wastewater is in compliance with local and state regulations before being conveyed to Three Rivers Regional Wastewater Treatment Facility. 

Best Management Practices

A component of stormwater and wastewater management, best management practices (BMPs) are taken to prevent water pollution. 

Spill Response

Spills, known in the port business as 'illicit discharge,' are the release of any liquid or material into a stormwater system or waterbody that are not exclusively stormwater. 

The Port primarily focuses on preventing spills. Port staff, unions and customers work together to keep the Port spill free. When a spill does happen, we have trained our teams to respond quickly to protect resources and generate appropriate reports. Want to learn more? Check out our Best Management Practices to see the specific actions we take every day to protect the land and water at the Port. 

Willow Grove Advanced Mitigation Site

A 308-acre, high-quality wetland site preserved for habitat and advanced mitigation for Port projects. The site was constructed in collaboration with Columbia Land Trust and agency partners the United States Army Corps of Engineers and the Washington Department of Ecology. 

Spirit Lake / Toutle-Cowlitz River Collaborative (SLTCRC)

In early 2021, The Gifford Pinchot National Forest and the Cowlitz-Wahkiakum Council of Governments (CWCOG) entered into an agreement with the Ruckelshaus Center to facilitate bringing local, state, federal, and tribal government entities together to develop an entity or collaborative to address long-term management in the Spirit Lake, Toutle/Cowlitz system. The driving force for this effort arose out of local and federal agency desire to efficiently address ongoing issues resulting from the 1980 eruption of Mt. Saint Helens.

The Port's Environmental and External Affairs departments participate in this collaborative.
