The auction begins Tuesday for the assets of the old Blue Heron Paper Mill in Oregon City. The mill was in business for over a century, and closed earlier this year after owners failed to find a buyer. The closure put about 175 people out of work. Officials with Capitol Recovery Group say more than 2600 items including storage tanks, spare motors, office furniture, copper cable and more will go up for bid during the three-day auction. A realtor is selling the 23 acre parcel separately.
