The U.S. Environmental Protection Agency will conduct a cleanup at Building #9 in the San Haven complex due to the presence of asbestos-containing materials which are a threat to human health.   EPA sampling and analysis showed that some of the building materials contain asbestos, which requires special management and disposal.  The Tribe made a request for an EPA cleanup in early 2021 when it was determined EPA had funding available this year for the cleanup project.

The EPA Emergency Response Program and its asbestos-certified cleanup contractors will begin cleanup on approximately  September 23, 2021.    The cleanup is anticipated to take approximately five weeks.  The cleanup contractors will wear special protective clothing and respirators during the portion of the cleanup involving asbestos.  The asbestos-contaminated debris will be wetted down with water prior to and during the cleanup to ensure that no asbestos fibers migrate from the debris piles.  The safety of the public is the highest priority.  All debris will be transported for disposal to an approved landfill.

Please try to avoid the area during the cleanup as there will be a considerable amount of truck traffic and movement of heavy equipment.  The site will be kept safe with security guards when the cleanup crew is not present at the site.

The Tribe received a Brownfields grant to address demolition and cleanup of some of the other buildings in the San Haven complex, which also have asbestos-containing materials.
