We invite you to review and comment on the draft periodic review report for the Northport City Park site.
The Northport City Park site is located on a parcel of land south of the Columbia River east of Highway 25 in Northport.
Beginning in 2004, approximately 7,714 tons of lead- and arsenic-contaminated soils were excavated and transported to a U.S. Environmental Protection Agency containment area on the nearby LeRoi Smelter site (Cleanup Site ID# 47). Some contaminated soil remains in place due to proximity to trees, railroad tracks, or several below-grade structures.
Engineered controls in the form of imported soil, rock, sod, and/or asphalt are in place to prevent human exposure or ingestion of soils. An environmental covenant was filed in 2010 to restrict activities that may interfere with the integrity of the cleanup action or result in exposure to contaminants remaining onsite. We visited the site on August 21, 2019, and found that the engineered controls remain intact.
Periodic review and public comment process
We conduct a periodic review every five years at independent cleanup sites where contaminated soil remains in place. The purpose of the review is to evaluate current site conditions and to ensure the continued protection of human health and the environment.
We will review comments received during the comment period and make recommendations for suggested changes. The periodic review will become final if no significant changes are made. An additional public comment period will be held if significant changes are made.
We will hold a public meeting if 10 people request one.
