Old Inland Pit cleanup site, Spokane Valley
Draft periodic review report
Nov. 13, 2023 - Dec. 15, 2023, 11:59 p.m.
We invite you to review and comment on the draft periodic review report, which includes the results of our site condition review to ensure cleanup is still protective.
We visited the site Oct. 31, 2022, and found the cleanup remains effective. The site is fenced and vacant.
We will review all comments received during the comment period and update the periodic review, if needed. If no significant changes are made, the periodic review will become final. If significant changes are made, we will hold an additional public comment period. We will hold an online public meeting if 10 or more people request one.
Site history and cleanup
Old Inland Pit was used as a source for sand and gravel from 1969 to 1978. Spokane Steel Foundry Company disposed of waste foundry sands and baghouse dust from May 1978 to May 1983.
Sample results collected in 1984 had elevated concentrations of copper, zinc, nickel, and chromium. Based on these results, the U.S. Environmental Protection Agency placed the pit on the National Priorities List in 1986.
No cleanup was done because additional sampling showed that the wastes at the site did not classify as dangerous under Washington law. The contaminant levels present were allowable for industrial uses of the property. A restrictive covenant was placed on the property in 1999 that limits how it may be used and documents remaining contamination.
About periodic reviews
Periodic reviews are required when institutional controls are required at a site. Institutional controls can be fences, signs, or restrictions on how the property is used. Ecology conducts reviews to make sure the controls remain effective and the cleanup still protects human health and the environment. We conduct periodic reviews about every five years.
