The Crow Agency Tribal Office building (Site) consists of a single-level building of approximately 30,000 square feet that was built in five separate sections from the 1930s to 1970s.  The main branch wing of the office building suffered a fire in 2019 which led to the entire office space being vacated.  The office space lies in the center proper of the Crow Agency township and is surrounded by residential homes.  The tribe made a request for EPA assistance for building demolition and removal of ACM and non-ACM building debris and waste. 

The EPA Removal Program is conducting a CERCLA cleanup to protect human health and the environment at the Crow Agency Reservation.  The main objectives consist of the following:

• Demolition of the main office wing containing Asbestos Containing Material (ACM) and transportation to a landfill in Miles City for proper disposal.
• Remove any residual ACM in separate wings of office space.  ACM-contaminated debris will be transported and disposed at the Miles City landfill.
• Demolition of remaining building wings not containing ACM and transportation to a C & D landfill for disposal.
• Maintain safety for working crews and local residents by properly securing area and using best engineering practices to control ACM, noise and any potential airborne dust.

Proposed weekly activities from 5/23 - 5/28/22 include the following:

• Equipment, resources, and personnel mobilization and set up,
• Coordinate w/local tribal contacts to secure electricity, water, blue-stake, night and Sunday security, and awareness to tribal residents on the commencement of activities,
• Coordinate w/transportation subcontractors to secure roll-off containers and drivers,
• Set up and secure perimeter zones including exclusion zones beginning with primary ACM building, and dental wing of office space,
• Air monitoring station set-up along perimeter of demolition activities.  First  3-4 days, collect background data prior to the onset of the removal action,
• Begin identification & removal of dental wing ceiling tile ACM, proper cleaning of inside area,
• Commence demolition on the primary burned out portion of the office building containing ACM.  Proper segregation of larger pieces of metal material for later decon & recycling.  Segregation of all other ACM for load out activities to begin on 5/31/22.
