Congressional Budget Office Cost Estimate: H.R. 5081, Surface Transportation Security and Technology Accountability Act of 2018 [open pdf - 86KB]
From the Document: "H.R. 5081 would direct the Administrator of the Transportation Security Administration (TSA) to establish a Surface Transportation Security Advisory Committee. The bill would specify details related to the composition and responsibilities of that committee, and it would require TSA to consult the committee when developing the agency's plan for making investments in security-related technology. Using information from the agency about the costs of similar activities, CBO [Congressional Budget Office] expects that any increased costs to establish and support the proposed advisory committee would not exceed $500,000 annually. Such spending would be subject to appropriation."
