Congressional Budget Office Cost Estimate: H.R. 3669, Weatherizing Infrastructure in the North and Terrorism Emergency Readiness Act of 2019 as Ordered Reported by the House Committee on Homeland Security on July 17, 2019 [open pdf - 30KB]
From the Document: "H.R. 3669 would require the Department of Homeland Security (DHS) to conduct an exercise to test whether DHS and local officials are prepared to respond to the effects of a terrorist attack that occurs during a winter storm. The bill also would require DHS to submit a report to the Congress on the results of the exercise. To perform the exercise required by H.R. 3669, DHS would use computer simulation models and facilitate the remote participation of homeland security personnel and local officials. The exercise would simulate the cascading consequences of disruptions to critical infrastructure such as power generation and transmission facilities. Using information about the costs of similar exercises, CBO [Congressional Budget Office] estimates that implementing H.R. 3669 would cost $1 million over the 2019-2024 period; such spending would be subject to availability of appropriated funds."
