DRAFT Environmental Assessment for Counter-Unmanned Aircraft Systems Testing at Multiple Sites

The U.S. Department of Homeland Security (DHS) Science & Technology Directorate (S&T) proposes to test C-UAS capabilities to detect, track, identify, and mitigate (DTI-M) small unmanned aircraft systems (sUAS). Five geographical testing areas are being considered in this Environmental Assessment (EA): Niagara Falls and Buffalo, New York; the greater Philadelphia, Pennsylvania area; Northeastern West Virginia; National Capital Region (NCR), Washington, D.C.; and Richmond, Virginia.  

This EA documents the analysis of any potential effects on the environment resulting from the Proposed Action. This EA is being coordinated with stakeholders and the public for information and comment, in accordance with the National Environmental Policy Act of 1969, 42 United States Code [USC] §§ 4321 et seq. (NEPA), the Council on Environmental Quality (CEQ) Regulations Implementing the Procedural Provisions of NEPA (40 Code of Federal Regulations [CFR] Parts 1500-1508), other relevant federal and state laws and regulations, DHS Directive 023-01, Revision 01, and DHS Instruction Manual 023-01-001-01, Revision 01, Implementing the National Environmental Policy Act.  

In 2018, Congress passed The Preventing Emerging Threats Act of 2018 (PL 115-254), granting DHS statutory authority to counter credible threats from UAS in the interest of national safety and security. The Proposed Action includes testing of five types of third-party C-UAS technology modalities to DTI-M sUAS. By definition, sUAS and their associated elements must cumulatively weigh less than 55 pounds on takeoff. The C-UAS systems being tested would be mounted on a tripod, which could be placed on the ground or on a vehicle. The C-UAS systems would have a detection range of up to approximately 1.2 miles. Tests will be limited in scope and temporary in duration at selected locations in the identified geographic areas.  

All C-UAS test events would be conducted by S&T-authorized personnel in conjunction with a participating Component or State partner and may be attended by other DHS Components, and other government, state, or local agencies. All C-UAS tests would be conducted during daylight hours with equipment test durations of one to several hours during test days. C-UAS technologies may be tested against one or more sUAS flown in distance and mission profiles designed to test specific systems and against individual test objectives. S&T will comply with all Federal Aviation Administration requirements for sUAS and C-UAS operations.  

All comments or questions on the Draft EA may be submitted within the next 30 days via e-mail at: CUAS-Test@hq.dhs.gov. It is important that any comments submitted include a reference to “C-UAS NEPA DRAFT EA”.
