Northwest Pipeline Mead

Facility Site ID: 680 Cleanup Site ID: 1811

Public Comment Period March 15, 2013-April 15, 2013

Ecology proposes to remove the Northwest Pipeline Mead Meter Station from the Hazardous Sites List.  The site is a natural gas meter station where gas is regulated and metered for distribution of natural gas to a local distribution company or customer. 
An assessment of the site was conducted in 1990.  Five drums of gravel and soil were removed from under and around the former meter stand to address inorganic mercury contamination.  The main source of the contamination was likely from accidental spills during maintenance and calibration of equipment used at the meter station.  Another source may have been from thermowells used to measure gas temperatures
In 2008 additional assessments were conducted to determine if mercury and arsenic were present in soils.  The level of mercury and arsenic in soil exceeded state standards, therefore cleanup was necessary.  Additional soils were removed from the site in 2011, and follow-up sampling indicates no further actions are required at this site to meet state cleanup standards. 
Ecology’s Voluntary Cleanup Program provided review of the cleanup actions at the site.  As a result of the completed work, Ecology plans to remove the site from the Hazardous Sites List, after public comment is received and considered.
