The Department of Justice and the Department of Homeland Security jointly issued an Interim Final Rule in July 2026 that sets binding requirements for state, local, tribal, and territorial law enforcement agencies that want legal authority to counter unmanned aircraft systems. The rule is the primary regulatory guidance for any SLTT agency seeking to implement C-UAS mitigation strategies, according to the official documentation.
Two Certification Tracks and Where Agencies Must Train
The IFR establishes two distinct types of certification. The first covers Detection and Warning. The second covers Mitigation. Both are separate tracks, and both are conducted at the National Counter-UAS Training Center, which the rule designates as the central hub for all training and certification protocols mandated by the new federal regulation. Agencies that want to operate at the mitigation level must complete the more demanding certification pathway before activating any C-UAS system for that purpose.
The rule does not allow agencies to self-certify or rely on vendor-provided training alone. The NCUTC is the required venue. That requirement applies to individual personnel as well as to the agencies themselves, according to the rule.
The Five-Minute FAA Notification Requirement
One of the most operationally specific provisions in the IFR is a hard deadline on FAA notification. Any SLTT agency that activates a C-UAS system for mitigation purposes must notify the Federal Aviation Administration within five minutes. The rule frames this as a real-time coordination requirement, not a post-incident reporting obligation.
That distinction matters. Five minutes is a narrow window during an active operation. Agencies will need to build notification protocols into their command structures before any deployment, not after. The rule does not describe a grace period or a waiver mechanism for the five-minute window.
Civil Liberties Limits and Constitutional Compliance
The IFR mandates that SLTT agencies and their personnel follow specific privacy and civil liberties protections when exercising C-UAS authority. The rule is explicit on one prohibition: C-UAS authority cannot be used solely to seize, monitor, deter, interfere with, or disrupt individuals who are exercising rights protected by the First Amendment. The word "solely" appears in the rule's framing, which means agencies will need to document the basis for any action that could be construed as targeting expressive activity.
The rule also requires that agencies maintain compliance with constitutional protections more broadly while using C-UAS tools. That obligation runs parallel to the certification requirements, not separate from them.
The IFR further clarifies a legal complication that has long created uncertainty for SLTT agencies. Law enforcement attempts to disrupt, disable, or destroy a drone may implicate federal laws that prohibit the seizing or destroying of an aircraft, according to the rule. That tension between state police power and federal aviation law is one reason a formal regulatory framework was necessary. The IFR addresses the gap but does not eliminate the underlying federal statutory restrictions — it provides the framework within which SLTT agencies can act without running afoul of those laws, provided they meet the certification and notification requirements.
Federal Task Forces, Contraband Drones, and the Grant Funding Picture
SLTT officers may be deputized to serve on FBI C-UAS task forces. The IFR provides the training and certification framework that governs their participation, according to the documentation. That pathway gives local agencies a route into federal operations without each agency needing to independently develop full mitigation programs.
The rule comes against a documented increase in drone-related threats. The Federal Bureau of Prisons and other federal agencies have reported rising drone incursions used to deliver contraband — illicit drugs, weapons, and cell phones — to inmates, according to the documentation. Policymakers have also cited reconnaissance for criminal activity and the potential for drones to drop hazardous materials or weapons over large crowds as concerns driving the regulatory push.
On the funding side, the SAFER SKIES Act expanded the scope of the Edward Byrne Memorial Justice Assistance Grant Program and the Community Oriented Policing Services Program to allow for the purchase and operation of approved C-UAS technology. That expansion means eligible SLTT agencies have a federal funding mechanism available to cover equipment costs, which had previously been a barrier for smaller departments.
The IFR is part of a broader federal effort to address public safety and security risks posed by the rapid increase in commercial and recreational drone use, according to the documentation. The July 2026 rule represents the clearest regulatory signal yet that DOJ and DHS intend to bring SLTT counter-drone operations into a structured, federally supervised framework — with real deadlines, mandatory training locations, and enforceable civil liberties obligations attached.
