Final rule.

The Department of Transportation is amending its drug-testing program regulation to add hydrocodone, hydromorphone, oxymorphone, and oxycodone to its drug-testing panel; add methylenedioxyamphetamine as an initial test analyte; and remove methylenedioxyethylamphetamine as a confirmatory test analyte. The revision of the drug-testing panel harmonizes DOT regulations with the revised HHS Mandatory Guidelines established by the U.S. Department of Health and Human Services for Federal drug-testing programs for urine testing. This final rule clarifies certain existing drug-testing program provisions and definitions, makes technical amendments, and removes the requirement for employers and Consortium/Third Party Administrators to submit blind specimens.
