There are also separate categories for asbestos (Part 61, Subpart M) and woodstoves (Part 60, Subpart AAA). Recently issued determinations are added to the database on a quarterly basis. The Office of Enforcement and Compliance Assurances (OECA), Compliance Assessment Media Programs Division (CAMPD) maintains the database. ADI allows users to search for determinations by a combination of categories, control numbers, subparts, regulatory citations (references), issue dates, EPA Region or office, author name, and word search strings connected with an "AND", an "OR", an "AND NOT", or an "OR NOT". Users can then view information from the determinations found including the header (which gives basic data about the determination), the determination abstract, and the full text of the determination. ADI users can select one or more determinations to download to their computers. The downloaded information will be in an ASCII text file that contains all of the selected determinations. The ASCII text file can be read or printed using a word processor or a text editor. For additional information on ADI or on a specific determination, please contact your EPA Regional Office.
