<br /> This document offers guidance on environmental concerns that need to be addressed prior to the
<br /> demolition of a building. The environmental concerns include: asbestos,hazardous wastes,special
<br /> hazardous wastes, underground storage tanks,wells, refrigerants/CFCs/HCFCs,fire extinguishers,
<br /> and other concerns. This document also includes guidance on what kinds of waste can and cannot
<br /> be accepted at a demolition landfill.

<br /> Asbestos-Containing Material (ACI) is a special consideration in the demolition of old buildings.
<br /> Through the 1970s asbestos was used in over 3000 different building materials. Some of the more
<br /> common materials are:
<br /> ♦ pipe, duct, and boiler insulation (includes many different types of ACM)
<br /> ♦ ceiling tiles, textured spray, fireproofing, scratch coats or other treated areas
<br /> ♦ cement asbestos board: also known as Transite®, this material was used extensively as siding on
<br /> homes, ceilings and walls in commercial buildings, and any area where heat or moisture is
<br /> present.
<br /> ♦ vinyl asbestos floor tile, old linoleum, and other resilient floor coverings
<br /> ACM can be found almost anywhere and a thorough inspection for ACM must be performed prior
<br /> to any demolition. The MPCA Air Quality Division Asbestos Team maintains a list of companies
<br /> that can perform this service for you. You can reach the Asbestos Team at the phone number
<br /> below.
<br /> In a demolition a notification form must be filled out and sent to the MPCA Asbestos Team ten
<br /> working days before any demolition is started whether the building contains ACM or not. If you
<br /> don't have this form, contact the Asbestos Team. The Notification form for a demolition contains
<br /> specific information on the dates of demolition and on the different types of ACM and conditions
<br /> for how the ACM needs to be handled if ACINI is present.
<br /> If any of the demolition materials are to be recycled it is necessary to remove any ACM that may be
<br /> present. The recycling process could result in previously resilient ACM becoming crushed,
<br /> crumbled, or reduced to a powder. If the ACINI is not removed prior to demolition then the
<br /> building materials containing, mired in with, or coated with ACM may not be used for recycle.
