## Abstract

In this action, the Environmental Protection Agency (EPA) is approving the St. Paul Park Area redesignation request submitted by the State of Minnesota on October 31, 1995. Minnesota requested that portions of Dakota and Washington Counties (the areas surrounding the Ashland Petroleum Company) be redesignated to attainment for the National Ambient Air Quality Standard (NAAQS) for sulfur dioxide (SO2). All future references to the areas surrounding the Ashland Petroleum Company will be made using St. Paul Park. Subsequent to this approval, Dakota and Washington Counties are each designated attainment in their entirety.
