State seeks to de-list Sunnyside location from hazardous sites

An Emerald Road location near Sunnyside formerly contaminated with mercury will be taken off of Washington state's list of hazardous sites.

That's according to a proposal announced recently by the state's Department of Ecology.

Called the NW Pipeline Sunnyside Meter Station, the site at 9390 Emerald Rd. formerly had equipment with mercury. That, in turn, led to mercury-contaminated soil.

Twenty years ago, state officials removed two drums of mercury-containing soil. Last year, 66.8 tons of mercury-contaminated soils were removed from the site.

The clean-up efforts have led to the pipeline site having a ranking of 3 on a scale of 1 to 5, with 5 being the least contaminated and 1 having the highest rank of contamination.

In addition, the Department of Ecology says the site has reached clean-up levels now allowing for unrestricted land use.

Based on the clean-up completed, state officials have determined the site does not pose a threat to human health or the environment.

Comments will be accepted on the proposal through Oct. 22 by calling Norm Peck at 509-454-7837, or sending an e-mail to Norm.Peck@ecy.wa.gov.

Following the public comment period, the Department of Ecology will review comments and, if no changes are necessary, the pipeline site will be removed from the hazardous sites list.
