The Use Category System (UCS) was developed and is maintained by the American Wood Protection Association (AWPA). It’s purpose is to provide a simple way of selecting the proper preserved wood product directly related to the appropriate AWPA Standard.

Best Management Practices, or BMPs, are recommended guidelines for the production and installation of preserved wood products destined for use in aquatic and wetland environments.
