Comment On Cleanup Agreement, Studies, And Plan

Información en Español

The TOC Facilities 01 179 site is in a commercial-residential area of Mountlake Terrace. It covers parts of three contiguous parcels of property at 24205, 24225 and 24309 56th Avenue West, plus part of the 54th Avenue West right-of-way. The 24205 property was the source of the contamination.

JYK Holdings, LLC, intends to purchase, cleanup, and redevelop the 24205 and 24225 parcels.

Ecology will oversee the cleanup. We invite the public to review and comment on these draft documents:

  • Prospective Purchaser Consent Decree: a legal agreement that directs JYK Holdings to implement an Ecology-approved cleanup action for the site once they have completed the purchase.

Exhibit B – Legal Description of Property
Exhibit E – Schedule of Work and Deliverables

  • Remedial Investigation/Feasibility Study: describes the contamination at the site, evaluates cleanup actions, and selects a preferred option.
  • Cleanup Action Plan: describes the selected cleanup action, which includes:
    • Rehabilitating and expanding the existing multi-phase extraction (MPE) remediation system on the site
    • Operating the MPE system for three years to treat residual groundwater contamination
    • Collecting soil and groundwater performance and confirmation samples
    • Capping or covering residual contaminated soil at the site, if necessary
    • Implementing institutional controls under an environmental covenant, if necessary
    • Providing engineered vapor intrusion mitigation at the site, if necessary
  • Public Participation Plan describes how Ecology will inform the community about the cleanup and ways to become involved.

Background

Time Oil operated a retail gasoline service station on the Source Property from 1968 to 1990. The Site encompasses portions of three contiguous parcels, the Source Property, Adjoining Property, and Drake Parcel, plus a portion of the 54th Avenue West right-of-way.

The Source Property contains a fenced remediation system compound surrounded by paved parking and unpaved vegetated areas. The Adjoining Property is developed with a vacant one-story commercial building and contains a fenced remediation system compound. The Source Property and Adjoining Property are unoccupied. The Drake Parcel is developed with a tavern known as the Getaway Tavern.

Underground Storage Tanks

The service station included three underground storage tanks (USTs), six fuel dispensers, and associated product lines. In 1991, the USTs, fuel dispensers, and associated product lines were decommissioned by removal during closure of the service station.

Contamination

These contaminants remain in soil and groundwater at concentrations that exceed applicable cleanup levels:

  • Soil: Total petroleum hydrocarbons as gasoline-range organics (GRO), and benzene, toluene, ethylebenzene, and xylenes (BTEX)
  • Groundwater: GRO, benzene, and xylenes

Future Use

The Prospective Purchaser plans to redevelop the Property as a multi-story mixed residential and commercial building with parking after cleanup is completed. The redevelopment plans have not yet been finalized.

Model Toxics Control Act Cleanup Process

The Model Toxics Control Act (MTCA) is Washington’s environmental cleanup law. It
provides requirements for contaminated site cleanup and sets standards that
protect human health and the environment. Ecology enacts the MTCA and oversees
cleanups.

The MTCA site cleanup process is completed in steps over a variable timeline.
