How does the Department notify employers and the public about a PIE? § 40.401
(a) The Department maintains a document called the “List of Excluded Drug and Alcohol Service Agents.” This document may be found on the Department’s web site (http://www.dot.gov/ost/dapc). You may also request a copy of the document from ODAPC.
(b) When the Director issues a PIE, he or she adds to the List the name and address of the service agent, and any other persons or organizations, to whom the PIE applies and information about the scope and duration of the PIE.
(c) When a service agent ceases to be subject to a PIE, the Director removes this information from the List.
(d) The Department also publishes a Federal Register notice to inform the public on any occasion on which a service agent is added to or taken off the List.
