Congressional Budget Office Cost Estimate: H.R. 5484, State Sponsors of Terrorism Review Enhancement Act [open pdf - 23KB]
This is the Congressional Budget Office (CBO) Cost Estimate as ordered reported by the House Committee on Foreign Affairs on June 16, 2016. From the Document: "H.R. 5484 would reduce the President's flexibility to remove a country's designation as a state sponsor of terrorism by:  increasing the period of time the Congress would have to review any such proposed action[;]  increasing the period of time a country must refrain from supporting terrorism before the President could remove such a designation[;]  requiring the President to notify the Congress when the Administration initiates a review of a country's designation and, 20 days later, brief the Congress on the status of that review. CBO estimates that providing the notifications and briefings required by the bill would cost less than $500,000 over the 2017-2021 period; such spending would be subject to the availability of appropriated funds."
