Tiger Oil N 1st St Fmr 6013

Facility Site ID: 477 Cleanup Site ID: 4922

Site Description

The Site formerly operated as a gasoline station and is located at 1808 N 1st Street, Yakima, approximately 1200 feet from the confluence of the Naches and Yakima Rivers.  Bergland and Rotary Lakes are less than 600 feet to the north. 

Domestic well contamination was observed by neighbors from 1980 to 1982. Testing of equipment revealed leakage from the distribution system at the Site.  An estimated 12,000 to 22,000 gallons of leaded and unleaded gasoline and diesel was released from the facility.  Free product recovery was attempted and resulted in approximately 40 gallons recovered.

It is likely that a dissolved gasoline plume and possible that the NAPL plume extends off the property. 

The Site is currently on Ecology’s Hazardous Sites List with a ranking of “3”.  Sites on the Hazardous Sites List are a priority for Ecology, and have completed a Site Hazard Assessment (SHA).  A SHA provides information about the environmental risk of the Site. Risk is based on the amount of contaminants, how toxic they are, and how easily they can come in contact with people and the environment.  Sites are ranked relative to each other on a scale of “1” to “5”; with a rank of “5” being the lowest.

What’s Been Done?

Preliminary results from the 2014 site investigation shows contamination appears to to be confined to the former Tiger property with the possible exception of the eastern boundary of the dissolved plume in the groundwater. At the downgradient portion of the plume near MW-2, groundwater concentrations of nitrate/nitrogen and dissolved oxygen indicate that natural attenuation is occurring.
 
Groundwater monitoring continued through the first half of 2015. This monitoring assessed of fluctuations in contaminant levels and groundwater flow direction. Soil sampling was conducted in 2014 and 2016.

In 2017, a Remedial Investigation was done. This investigation summarized all of the existing environmental data and includes the soil and groundwater sampling. The results of the soil sampling revealed petroleum contamination appears limited to the north half of the site in the vicinity of the former USTs and dispenser islands and to the east partially beneath North 1st Street. Groundwater sampling reveals impacts from the gasoline release is limited to the immediate vicinity.

What's Next?

In 2015, the City of Yakima purchased the property. With contributing funding from Ecology,  plans for cleaning up the contamination is ready to be executed. Findings from the remedial investigation and feasibility study recommends an interim action to address the contamination. In early 2021, Ecology and the City of Yakima are entering into an Agreed Oder for the interim action to clean up the site.
