Stubblefield Salvage Yard
595 Offner Rd, Walla Walla, WA 99362

PUBLIC COMMENT PERIOD JUNE 01, 2020-JUNE 30, 2020

Draft Remedial Investigation and Feasibility Study Report and Public Participation Plan

You are invited to review and comment on the draft Remedial Investigation & Feasibility Study (RI/FS) and Public Participation Plan (PPP) for the Stubblefield Salvage Yard site. The RI explains the extent and locations of contaminants at the site, and the FS presents cleanup options. The PPP describes ways Ecology will inform the public throughout the cleanup process. This plan identifies how and when the public can get involved during different stages of the investigation and cleanup of contamination.

You can learn more in the notice that was mailed to addresses around the site.

Next steps

Ecology will respond to all the comments we receive by June 30 and publish our responses. We will hold an online public meeting on this proposal if 10 people request it. If public comments result in substantial changes to our proposal, we will hold another comment period.


SITE BACKGROUND

The Stubblefield Salvage Yard site is an approximately 11-acre site that operated as a fat-rendering plant from approximately 1945 to 1950, and as a salvage yard from approximately 1950 to 2010. In addition to the salvage yard activities, the site also housed a large amount of waste and debris including batteries, transformers, car bodies, and drums filled with waste materials. The site contained both soil and groundwater contamination at levels exceeding state and federal standards due to its historic operations.

SITE HAZARD ASSESSMENT RESULTS

In 2007, Ecology completed a site hazard assessment following an unannounced dangerous waste compliance inspection that resulted in the site being added to the confirmed and suspected contaminated sites list. Stubblefield was ranked a one, which represents the highest level of concern relative to other sites in Washington.

To assess potential hazards posed to humans and the environment if a site is not cleaned up, an Ecology staff member visits the site to gather basic information. Sites are ranked on a scale of one to five. 

During the assessment, Ecology confirmed obvious releases to the environment, such as: 
  • Used motor oil and other heavy oils, likely diesel and gasoline spills from engine and car dismantling activities
  • Brake fluid (hydraulic fluids) 
  • Lead and acid contamination from damaged batteries lying uncovered on the ground 
  • Polycyclic aromatic hydrocarbons from used oil spills and burning of various automobile components

ENVIRONMENTAL PROTECTION AGENCY (EPA) ACTIONS

In 2009, the EPA visited the site and documented the presence of oil-stained soil, unlabeled drums, several large open-top tanks, and other types of uncontrolled wastes including transformers and asbestos-containing material (ACM). EPA initiated a time-critical Removal Action to remove the drums, excavate selected surface soil contamination, and mitigate damaged ACM siding from the shop building and ground. 

EPA also performed a removal site evaluation from 2009 to 2012. This evaluation assessed the extent of soil and groundwater contamination in the northern portion of the site. In May and June 2013, EPA excavated and disposed of contaminated soil from the northern portion of the site. The excavated areas were backfilled with clean soil and graded to their pre-existing conditions.

Though the EPA remediated a portion of the site, contamination greater than Model Toxics Control Act (MTCA) cleanup levels still remains at the site, and the extent of contamination at the site has not been fully defined. Documents related to EPA’s actions at the site can be viewed from their Stubblefield Salvage website.


CONTAMINATION

Contaminants confirmed or suspected to be at the site in soil and/or groundwater include:

Surface water runoff into Mill Creek, which forms the northern border of the site, has likely been prevented by berms and other site features.
