Richland Uptown Shopping Center Parcel 10

The Richland Uptown Shopping Center Parcel 10 site was originally part of a larger site known as the Richland Uptown Shopping Center. The Uptown Shopping Center, previously owned by the US government, was obtained by private parties in the late 1950s and early 1960s with the development of the shopping center. The City of Richland presently owns the parking lot and service alley encompassing the shopping center.

During a 1993 Phase I Site Assessment, 32 underground storage tanks (USTs) were identified in and adjacent to the service alley; the tanks reportedly stored heating oil. In addition to the USTs, past or present businesses that may have stored or used hazardous materials at the site include print shops, dry cleaners, camera shops, paint stores, and automotive supply stores. The larger site was subsequently split into separate sites based on information indicating separate releases had occurred at different parcels within the larger site.

The Richland Uptown Shopping Center Parcel 10 site is the location of four heating oil underground storage tanks (USTs); two tanks have been removed and two tanks remain on site. Petroleum contaminated soil above MTCA cleanup levels has been reported. "Free product" petroleum floating on groundwater has also been reported at the site.
