Tri City Battery Goodyear

The Tri City Battery Goodyear site previously housed an automotive service shop. An asphalt parking lot contained a drywell for stormwater drainage.

In 2008, the site was added to Ecology’s Hazardous Sites List with a ranking of “2”. 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.

The cleanup action selected for this Site was excavation and removal of contaminated soils to a landfill. 

Contaminated soils were excavated and removed from a former drywell on the site.  Approximately 267 tons of excavated soils were disposed of at Finley Buttes Landfill.  Some residual contamination was left in place because proximity to adjacent buildings made it unsafe to enlarge the excavation. 
 
Groundwater monitoring wells constructed at the site and monitored.  Results from four consecutive quarters of monitoring indicated that contaminants of concern were below MTCA cleanup levels.

Based on the completed cleanup and the confirmation sampling results, Ecology determined the site is no longer a threat to human health and the environment. Ecology issued a no further action determination in October 2010. The Site has been removed from the Hazardous Sites List.
