Notice of proposed rulemaking.

The Department of Transportation is proposing to amend its drug-testing program regulation to add four opioids (hydrocodone, hydromorphone, oxymorphone, and oxycodone) to its drug-testing panel; add methylenedioxyamphetamine (MDA) as an initial test analyte; and remove methylenedioxyethylamphetamine, (MDEA) as a confirmatory test analyte. The proposed revision of the drug-testing panel is intended to harmonize with the revised Mandatory Guidelines established by the U.S. Department of Health and Human Services for Federal drug-testing programs for urine testing. This proposal also adds clarification to certain drug-testing program provisions where necessary, removes outdated information in the regulations that is no longer needed, and proposes to remove the requirement for employers and Consortium/Third Party Administrators to submit blind specimens.
