Types of Advisory Committees

There are two types of advisory committees: non-discretionary and discretionary. A non-discretionary advisory committee is one that is specifically required by statute or mandated by the President. A discretionary advisory committee is established at the discretion of the head of a federal agency. An advisory committee that is authorized, but not specifically required by law, is also considered a discretionary committee.
Note: At EPA the primary committee is often referred to as a "Tier 1" committee, and a subcommittee as a "Tier 2" committees
