JH Baxter & Co Inc.

Periodic Review

Sept. 22, 2022 - Oct. 21, 2022, 11:55 p.m.

Ecology conducts reviews about every five years when some contamination remains on-site. Periodic reviews evaluate current site conditions to ensure continued protection of human health and the environment.

The JH Baxter & Co Inc. site is on the southeastern shore of Lake Washington. A wood treatment plant  operated at the 20-acre property from 1955 until it was closed in 1982.

The plant used chemicals commonly associated with industrial treatment of wood, including creosote for railroad ties and pilings and pentachlorophenol (PCP) for poles.

On May 18, 2000, Ecology entered into prospective purchaser consent decrees with the Port Quendall Company, who subsequently purchased the site from J.H. Baxter. The cleanup included excavation and treatment/disposal of soils and sediments, in-place soil solidification in former process areas, capping of residual soil impacts, and the creation of a 0.46-acre forested wetland to enhance shoreline habitat. Institutional controls were implemented in the form of environmental covenants.

The 2022 Periodic Review concluded that the cleanup actions completed at the site still appear to be protective of human health and the environment. The environmental covenants are in place. Groundwater compliance monitoring indicates that all constituents of concern continue to be below groundwater cleanup levels.

We will review all comments received during the comment period. The periodic review will become final if no significant changes are made.

We will hold a public meeting if 10 people request one.
