Cybersecurity and Infrastructure Security Agency, DHS.


Announcement of availability; request for comments.


Through this document, the Cybersecurity and Infrastructure Security Agency (CISA) is making available a retrospective analysis of the data, assumptions, and methodology used to support the 2007 interim final rule for the Chemical Facility Anti-Terrorism Standards (CFATS) program. The purpose of the retrospective analysis is to provide an updated assessment of the costs and burdens of the CFATS program. Based on data observed by the program for over ten years, CISA estimates that the actual costs of the CFATS program is 83 percent lower than estimated in 2007. The retrospective analysis has been added to the docket for the CFATS Advanced Notice of Proposed Rulemaking (ANPRM) published in 2014.


Comments are due by September 21, 2020.

The Department published an ANPRM on August 18, 2014 seeking public comment on the CFATS interim final rule (IFR) published in 2007 (72 FR 17687) and a final rule for Appendix A to the CFATS regulations published in 2007 (72 FR 65395). The 2014 ANPRM was an initial step towards maturing the program. See 79 FR 48693 (August 18, 2014). To better inform the ongoing rulemaking process, CISA has performed a retrospective analysis of the costs and burdens of the 2007 CFATS IFR on regulated facilities.[1] The retrospective analysis updates cost estimates from the 2007 CFATS IFR with new estimates based on data observed from the implementation and operation of CFATS over the last decade. CISA intends to use the retrospective analysis: (1) To improve the accuracy of cost estimates incurred by regulated facilities since 2007; (2) as a basis for future regulatory changes to the CFATS program; and (3) to perform cumulative impact analysis on the full costs of the program as it evolves.

Based on the retrospective analysis, CISA believes that the regulatory impact assessment (RIA) for the 2007 CFATS IFR overestimated the costs of the program imposed on chemical facilities and that the actual costs are 83 percent lower than previously estimated. Because CFATS was a new regulatory program that was developed under a six-month Congressional deadline, there was limited time to conduct economic studies and collect data to establish the pre-statutory security baseline at high-risk chemical facilities.[2] As CFATS was a new program, there was no historical data that could inform the analysis. In order to meet the Congressional deadline, the Department relied heavily on the elicitation of subject matter expert (SME) judgment to estimate the cost of the regulation in the 2007 RIA. Now that CISA has fully implemented CFATS, CISA was able to replace the SME judgments with historical data provided by industry through the Chemical Security Assessment Tool, CFATS compliance data, and lessons learned. As a result, the retrospective analysis provides a more accurate estimate of the cost that the CFATS program imposed on chemical facilities between 2007 to 2017. The retrospective analysis resulted in a decrease in the estimated 10-year cost, discounted at 7%, of CFATS from $9.84 billion to $1.68 billion. The main drivers of this substantial reduction in cost were the 2007 CFATS IFR's overestimation of: (1) The number of chemical facilities that would be covered by CFATS; and (2) the costs of security measures implemented by CFATS covered facilities.

CISA encourages public comment on the retrospective analysis. Commenters Start Printed Page 37394can find a copy of the analysis in the docket. Comments that will provide the most assistance to CISA will refer to a specific section, appendix, figure, and/or table of the analysis, explain the reason for any comments, and include other information or authority that supports such comments.

See Public Law 109-295, sec. 550. Section 550 required the Secretary of Homeland Security to promulgate interim final regulations “establishing risk-based performance standards for security of chemical facilities” by April 4, 2007.
