Orchard Middle School
Facility Site ID:
771247
Cleanup Site ID:
447
Site Description
The school is located on former orchard property and was subject to historical pesticide applications. Soil samples taken in 2002 confirmed lead and arsenic at concentrations exceeding state cleanup levels.
After a Site Hazard Assessment, the site was ranked a “3” on the Hazardous Sites List. The Hazardous Sites List is a statewide list of contaminated properties. Sites can be ranked from a “1” to “5”. A rank of “1” is the highest level of environmental concern compared to other sites on the List, and a rank of “5” is the lowest.

Cleanup Activities
During the summer of 2008, Ecology conducted a cleanup and placed all contaminated soils under a geotextile fabric barrier. Then, six inches of clean topsoil were placed on top on the barrier fabric. This cleanup method, referred to as capping, is cost-effective and prevents human exposure to contaminated soil.
Following cleanup, an environmental covenant was recorded for the property with the Chelan County Assessor. The purpose of the environmental covenant is to provide a permanent legal record of the contamination that remains on the property, and to prevent activities at the site that might disturb or damage the soil cap.

Cleanup Complete
Based on the cleanup completed and the recording of the environmental covenant, Ecology has determined the site does not pose a threat to human health or the environment. Ecology issued a no further action determination in April 2011. The site has been removed from the Hazardous Sites List.
Site use restrictions called institutional controls are in effect
Institutional controls can be fences, signs, or restrictions on how the property is used. For instance, an institutional control may prohibit installing drinking water wells or disturbing a protective cap that isolates contamination. These restrictions keep the contamination contained and keep people from being exposed to the contamination. The controls are usually listed in environmental covenants recorded with the county.
Periodic reviews are required when institutional controls are required at a site. 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.

Public Comment Period
Comments will be accepted October 30, 2024 through November 29, 2024.
You may submit your comments online or by mail to Frank Winslow, Periodic Reviewer, at Ecology's Central Regional Office.
We complete a periodic review about every five years cleanup construction is complete at a site when institutional controls are part of the cleanup. The purpose of the review is to make sure the controls remain effective and the cleanup still protects 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.
