This is the Congressional Budget Office Cost Estimate as ordered reported by the House Committee on Homeland Security on July 17, 2019. From the Document: "H.R. 3699 would restate the role of the Transportation Security Administration (TSA) within the Department of Homeland Security in administering the department's program to protect pipelines from terrorists. The bill also would authorize TSA to develop a personnel strategy to enhance the effectiveness of that program and to report to the Congress. Finally, H.R. 3699 would require the Government Accountability Office to report on the bill's implementation. Because TSA is already pursuing activities similar to those called for in the bill, CBO [Congressional Budget Office] estimates that implementing H.R. 3699 would have no significant effect on spending subject to appropriation."
