Drug Enforcement Administration April 23, 2007 – Federal Register Recent Federal Regulation Documents

This rulemaking controls the chemical N-phenethyl-4-piperidone (NPP) as a List I chemical under the Controlled Substances Act (CSA) (21 U.S.C. 801 et seq.). Clandestine laboratories are using this chemical to illicitly manufacture the schedule II controlled substance fentanyl. The recent distribution of illicitly manufactured fentanyl has caused an unprecedented outbreak of hundreds of suspected fentanyl- related overdoses, at least 972 confirmed fentanyl-related deaths, and 162 suspected fentanyl-related deaths occurring mostly in Delaware, Illinois, Maryland, Michigan, Missouri, New Jersey, and Pennsylvania. NPP has been identified as the starting material in several seized fentanyl clandestine laboratories. In addition to DEA's concern regarding the deaths associated with illicitly manufactured fentanyl, DEA is extremely concerned about the safety of law enforcement officers encountering these clandestine laboratories. Therefore, DEA is regulating NPP as a List I chemical through this Interim Rulemaking. DEA is soliciting comments on this Interim Rule. This rulemaking will subject handlers of NPP to the chemical regulatory provisions of the CSA and its implementing regulations, including 21 CFR Parts 1309, 1310, 1313, and 1316. This rulemaking does not establish a threshold for domestic and international transactions of NPP. As such, all transactions involving NPP, regardless of size, shall be regulated. This rulemaking also specifies that chemical mixtures containing NPP will not be exempt from regulatory requirements at any concentration. Therefore, all transactions of chemical mixtures containing any quantity of NPP will be regulated and will be subject to control under the CSA.
