Work on the most contaminated former Tiger Mart site in Yakima is expected to start within the next month thanks to $500,000 grant from the state Department of Ecology.

Yakima City Manager Tony O'Rourke says the store at 24th Avenue and Nob Hill Boulevard leaked 20,000 gallons of gas between 1982 and 1984.

The plan using the money from the Department of Ecology is to remove additional contaminated soils and then ground water monitoring of that site.

The other three sites will be cleaned up after the Nob Hill site. O'Rourke would not say when the work will be completed, but he is hoping it is sooner than later so the city, which owns the contaminated sites, can sell them to developers who will create jobs and new businesses.

The other sites are at 1808 N. First St., 16th Street and East Nob Hill Boulevard, and 56th and Summitview avenues.
