The Mt. Baker Housing Association (MBHA) is cleaning up the Mt Baker Properties Cleanup Site (Site) in Seattle, with Department of Ecology (Ecology) oversight. Ecology is hosting a public comment period for a legal document related to this process. The document is an amendment to a "Prospective Purchaser Consent Decree," or PPCD. It provides for the funding, and tracking of funding, for the cleanup process. It also requires MBHA to provide affordable housing once cleanup is completed.

Ecology hosted a previous comment period in the Fall of 2019 for other related documents. This PPCD Amendment was not yet ready for comment at that time, so Ecology is now hosting this second comment period for it.

Comments regarding the PPCD Amendment can be submitted through the contacts to the right of this page, or with Ecology's e-comment system.  Comments will be accepted from February 3 - March 3, 2020.

You can view the other related documents for this cleanup by following the links below (please note these are NOT now available for public comment since they already went through the public comment process and have been finalized):

• Remedial Investigation/Feasibility Study Report (RI/FS) Describes contamination at the Site and evaluates five cleanup alternatives.
• Cleanup Action Plan (CAP) – Describes preferred cleanup methods for contamination and specifies cleanup standards and requirements at the Site.
• State Environmental Policy Act (SEPA) Checklist and Determination of Non-Significance (DNS) – Ecology evaluation and determination that the cleanup action will not have a negative impact on the environment.

Over the last several decades, businesses operating at the Site released hazardous substances at the Site. The Site includes all areas where contamination has come to be located from releases at Mount Baker Cleaners and a former retail gas station. Contamination from petroleum and solvents (volatile organic compounds or VOCs) is commingled at the Site.

Former Gas Service Station Parcel (south side of S McClellan Street):
A gasoline station operated at 2800 Martin Luther King Jr. Way S from the mid-1950s to mid-2000s (most recently Phillips 66 #070644). From the 1990s until 2004, the property was used as an auto repair business. Environmental sampling also found solvent contamination on the property. Three underground storage tanks were removed in 1989. In 2005 other gas/service station equipment was removed and a petroleum-related release was reported to Ecology in August 2005. In 2005–06, several soil and groundwater borings were advanced. In 2005, five ozone injection points were installed, ozone was applied. This system operated until 2007, when additional treatment was conducted through in-situ chemical oxidation. Since 2010, Phillips 66 has conducted additional sampling at the property through Ecology’s Voluntary Cleanup Program (VCP), but no additional cleanup. 

McClellan Parcels (north side of S McClellan Street):
The other four properties purchased by MBHA, including the Mt. Baker Cleaners property, are collectively referred to as the “McClellan Parcels”. Mt. Baker Cleaners has been operating at 2864 S McClellan Street since the early 1950s. It is the source of dry cleaning related contamination beneath the McClellan Parcels and other surrounding properties and rights of way. Chlorinated and non-chlorinated VOCs have been detected on the property. There have been no remedial actions associated with this property.

The Mt Baker Properties Cleanup will pave the way for MBHA to move forward with redevelopment of these properties. Under Ecology oversight, MBHA will clean up these properties by addressing contamination and its sources. Once cleanup is complete MBHA will redevelop the properties for affordable housing. MBHA will build two affordable housing apartment buildings at the intersection of South McClellan Street and Martin Luther King Jr. Way South - Maddux North, on the northeast corner, and Maddux South on the southeast corner.

It will also redevelop multiple vacant or underused properties, create new, affordable housing in one of Seattle’s most diverse and economically-challenged neighborhoods, and promote affordable, sustainable, transit-oriented development. In February 2017, the City of Seattle signed a resolution to create its first Redevelopment Opportunity Zone (ROZ - See Below). The resolution opens the door for a new partnership between Ecology, Seattle, and the non-profit MBHA.

MBHA will be the first non-governmental organization to receive funds under the state’s Brownfield Redevelopment Trust Fund created in 2013. With the consent decree and ROZ in place, Ecology will provide $400,000 for environmental work on the site. The affordable housing project will eventually be financed with Low Income Housing Tax Credits, City of Seattle Housing Levy funds, and other sources.

Ecology’s Toxics Cleanup Program (TCP) manages or oversees contaminated site cleanups conducted under our state’s environmental cleanup law, the Model Toxics Control Act (MTCA). In 2013, amendments to MTCA established three tools intended to help local governments clean up brownfield sites: 
  • Redevelopment Opportunity Zones (ROZs)
  • Brownfield Renewal Authorities
  • Brownfield Redevelopment Trust Fund Account
A brownfield site is an abandoned or underused property where reuse or redevelopment is hindered by the release (or threatened release) of hazardous substances, such as might occur at a former dry cleaners or an abandoned gas station. Since 2013, three local governments have created ROZs – Spokane, Bellingham, and Seattle. Within these zones, local governments are authorized to:
  • Create a “brownfield renewal authority” with broad powers to facilitate cleanup and redevelopment (see RCW 70.105D.160).
  • Access a “brownfield redevelopment trust fund account,” created within the state’s budget, which can be used to secure long-term funding for cleanup (see RCW 70.105D.140).
Within these zones, Ecology is authorized to:
  • Enter into agreed orders with prospective purchasers to accelerate the study of sites with redevelopment potential.
  • Enter into mixed funding settlement agreements with prospective purchasers where public funding is commensurate with a public benefit other than cleanup.
  • Prioritize grants for integrated planning and area-wide groundwater remedial actions within these zones.
