2022 Cleanup Update


2022 Cleanup Update Fact Sheet 

The community of Skykomish came together and worked with the Department of Ecology and BNSF Railway to accomplish a very complicated cleanup. Monitoring and efforts to improve efficiency continue to this day.

The 2022 Cleanup Update Fact Sheet provides an update on efforts at the Skykomish School (page 3), the railyard groundwater containment system (pages 4 – 5), and the containment system’s passive operation pilot study (page 5). 

Virtual town council meeting 
Ecology’s site manager and outreach specialist will virtually join the Skykomish Town Council meeting to provide an update on the cleanup and answer questions.

Site Description & Background

Historic Skykomish Railyard
Historic Skykomish Railyard
The former railway maintenance and fueling facility in the Town of Skykomish was operated by BNSF Railway Company. Historical activities at the site included refueling and maintaining locomotives and operating an electrical substation. These activities resulted in the release of petroleum and heavy metals to the surrounding environment. BNSF is conducting the cleanup of the contamination at the site with Ecology oversight.

Significant achievements from the Skykomish Cleanup to date:
  • Over 350,000 tons of contaminated soil removed;
  • Over 218,000 gallons of oil removed and recycled;
  • Over 20 million gallons of contaminated water treated;
  • 21 properties cleaned with structures moved and restored;
  • 2 wetlands cleaned and restored;
  • Maloney Creek channel improved for habitat and reduced flooding;
  • Completion and operation of a town waste water treatment system;
  • Hot-water flushing was used under the historic Skykomish School.
  • A barrier wall and treatment system were constructed along the north side of the railyard.

Major Projects Within The Skykomish Cleanup

Installation of HCC treatment gate system, 2008
Installation of HCC treatment gate system, 2008

Railyard Barrier Wall (HCC)
The Hydraulic Control and Containment (HCC) system was originally designed to meet cleanup objectives by actively pumping sufficient volumes of contaminated groundwater to prevent northward flow through the carbon filled treatment gates.  The carbon filled gates were designed as a redundant component of the system that would provide treatment should there be a loss of power to the pumps.
 
BNSF initiated a 12-month Hydraulic Control and Containment (HCC) System Passive Operation Pilot Study (Pilot Study) in January 2019.  The purpose of the Pilot Study is to evaluate the HCC system’s ability to meet the cleanup objectives through passive operation.  Passive operation of the HCC system would turn off the pumps and rely on the HCC barrier wall and passive flow of contaminated groundwater through the carbon filled treatment gates as the primary means of treatment.  Passive operation can also utilize active groundwater pumping and treatment operations as a redundant means of containing contaminated groundwater on the BNSF railyard property if necessary.
 
Results of this Pilot Study will be used to inform Ecology’s decision on the future method for operating the HCC System. 


Skykomish School Cleanup
The Department of Ecology approved the completion of operations of the Hot Water Flushing (HWF) Treatment System at the Skykomish School. The system operated in the summers of 2016 and 2017 and met cleanup goals.

Ecology based this decision on data provided in The 2017 Hot Water Flushing Remediation Performance Report, dated April 2, 2018.

In 2018, the treatment system was decommissioned, the sheet-pile barrier around the school was removed, and site restoration took place around the school.
 
Treatment Facts:

  • 14 million gallons of contaminated groundwater treated;
  • 54 gallons of dissolved oil removed from the contaminated groundwater;
  • 98 gallons of oil removed by the oil recovery system. ​ ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

Ecology will continue to oversee vapor monitoring within the school, and groundwater monitoring outside the school to insure the safety of students, school staff, the community, and the environment.


Former Maloney Creek-East (FMC-E) Wetland/Upland Project

Cleanup work was successful on Maloney Creek and the Former Maloney Creek -East Wetland in 2011.  Maloney Creek was dredged and the sediment used to fill in FMC-E Wetland.  In 2009 and 2010,  Ecology worked with BNSF and the Town to develop a new way to approach the cleanup of the FMC-E Wetland.  The Cleanup Action Plan (CAP) originally called for the FMC-E Wetland to be excavated and replaced.  That plan did not address issues such as habitat restoration outside of the wetland, flooding in Skykomish, or land uses envisioned by the citizens of Skykomish in 2005 when they developed the Vision for Skykomish document, which was a major driver of the CAP.  The 2011 cleanup work incorporated those elements and was more consistent with the original vision of the citizens of Skykomish by taking a more global approach to the cleanup of the FMC-E Wetland.

Community Waste Water Treatment System (WWTS)
One of the biggest elements to the Skykomish cleanup was the construction of a new waste water treatment system. Construction on the system got started in 2008, and proceeded through 2010. Now, all hookups are complete on the system, and it is running smoothly. The Town is now moving forward on its own to develop Phase 3 of the WWTS, which will take service across the river to businesses there, and on to the Sky Lane Community. Any questions on these efforts can be directed to the Town of Skykomish at 360-677-2388.
