This is the Congressional Budget Office Cost Estimate as ordered reported by the House Committee on Homeland Security on May 18, 2021. From the Document: "H.R. 3243 would codify the role of the Transportation Security Administration (TSA) as the administrator of the Department of Homeland Security's program to protect pipelines from terrorists and cybersecurity threats. The bill would require TSA to create a new executive position, develop a personnel strategy to improve the effectiveness of the pipeline security program, and report on its progress annually. Finally, H.R. 3243 would require the Government Accountability Office (GAO) to review the bill's implementation within two years of enactment."
