Cleanup

 

Alcoa & Longview
Over the last 12 years, developing and implementing sound environmental remediation solutions for the former Reynolds Aluminum Smelter in Longview, WA has been the focus of many in Southwest Washington and Cowtlitz County. Through cooperative relationships, Alcoa, Northwest Alloys, local citizens, state and federal agencies and scientists have worked together to determine the best cleanup solutions for the port.

 

The Issue
Reynolds’ activities during operations between 1941-2000 at the Reynolds Longview Reduction Plant resulted in environmental impacts at the site. For over a decade, we have been working hard to remedy that.  We are now working with Millennium Bulk Terminals Longview, LLC (Millennium) and all regulatory agencies to move the process forward and accomplish a full site clean-up as thoroughly and as soon as possible, allowing the property to be reused to its full potential as a port site and part of a working waterfront.

 

The Solution

Northwest Alloys, a subsidiary of Alcoa, has undertaken the clean-up and has invested millions of dollars developing and implementing solutions for the Longview Site and Terminal. In addition, we along with Millennium have held numerous public meetings, and regularly work with our Longview Community Advisory Board, a dedicated group of community leaders who have volunteered to provide guidance and advice on the clean-up process. Significant progress has already been made and some major clean-up activities have been completed.

Progress and Next Steps

In 2007, Northwest Alloys and Millennium signed an agreed order with the Department of Ecology to complete a Remedial Investigation and Feasibility Study (RI/FS).  The purpose of the RI/FS is to investigate the nature and extent of impacts at the site and identify clean-up options.  In the fall of 2011 Northwest Alloys and Millennium submitted a report with preliminary testing results from the site to the Department of Ecology. Since that time, Northwest Alloys and Millennium have continued to work through this important process with Ecology and a significant amount of additional sampling and laboratory analysis has been completed.  In Q1 2012, Ecology replaced the original agreed order with a new agreed order, superseding the 2007 agreed order.  Northwest Alloys submitted an updated RI/FS to Ecology in March 2012, detailing contamination and feasibility of possible cleanup options at the site.  Ecology delivered comments on the draft RI/FS in June 2012 which has triggered work by all entities on a draft Cleanup Action Plan and Consent Decree.

 

In May 2014, Northwest Alloys submitted an updated RI/FS, detailing over 18,000 chemical measurements of soil, surface water, groundwater and sediment along with extensive testing and engineering to support possible clean-up alternatives.

 

The preferred alternative (#4) put forward in the draft Feasibility Study is protective of the environment and community. Alternative #4 includes redundant protective measures and technologies that have proven effective at other former smelter clean-up sites. By removing certain wastes, consolidating and capping less hazardous materials, and providing for further groundwater treatment at key locations, Ecology has developed a preferred clean-up alternative that strikes an appropriate balance between cost and further removal of contaminated materials consistent with its MTCA Rules.  This port site is an industrial property and should be treated as such, returning it to be reused as part of a healthy working waterfront in Southwest Washington state.

  

Ecology held a public comment period from June 2 through August 1, which included several public workshops and a formal hearing. Ecology will evaluate and respond to public comments and begin work on a draft Clean-up Action Plan (CAP) in late 2014.   

 

In 2015, Ecology plans to hold a public comment period and formal hearing on the Draft CAP and Consent Decree to implement the CAP.
