(a)Represents environmental and NRD liabilities assumed in the merger with Pope Resources. Pope & Talbot Inc. operated a sawmill from 1853 to 1995 and conducted shipping, log storage, and log transfer operations in the Port Gamble Bay area from 1974 to 2004. P&T’s operations resulted in the release of contaminated materials to the townsite, millsite, and adjacent bay. Prior to the merger, the in-water portion of the clean up was completed. In November 2020, a consent decree, which includes a cleanup action plan, was entered in Kitsap County Superior Court. Negotiations with the Trustees relating to NRD liabilities are currently ongoing and will ultimately result in agreement as to requested mitigation activities.
