PHMSA and TSA
PHMSA and the Transportation Security Administration (TSA) have a mutual interest in ensuring coordinated, consistent, and effective activities that improves interagency coordination on transportation security and safety matters.
On August 9, 2006, PHMSA and TSA signed an annex to the Memorandum of Understanding (MOU) between the DOT and Department of Homeland Security (DHS).
The annex to the MOU clearly delineates the lines of authorities and responsibilities and promotes efficiency, communication, and non-duplication of effort through cooperation and collaboration between the Administrations in the area of transportation security based on existing legal authorities and core competencies.
