Superfund Site Profile
The 50-acre North Market Street site is located in Spokane, Washington. The Phillips Petroleum Company, Tosco Refining Company and Chevron operated a petroleum refining and distribution complex at the site beginning in the 1980s. Site operations, discharge of hazardous liquid wastes to unlined waste ponds, and major oil spill incidents contaminated on-site soil and groundwater with petroleum and chemicals. Following cleanup, operation and maintenance activities are ongoing.
