DHS Notifies Chemical Facilities of Revised Tiering Assignments

July 5, 2011

In the last week, the Department of Homeland Security (DHS) has communicated with chemical sector organizations and individually notified certain high-risk facilities of revised tiering assignments affecting a limited number of facilities covered under the CFATS program.

DHS uses risk assessment computer programs to help DHS identify facilities that are high-risk. Following a DHS review of the results of one of the risk assessment tools that revealed some apparent anomalies, the Department replaced modeling data in one part of the tool, potentially affecting the tiering assignments for facilities with certain chemical holdings. DHS subsequently re-evaluated the tiering assignments for those facilities and adjusted the tiering in some cases.

None of the affected facilities will receive a higher-risk tier assignment as a result of this re-evaluation. In fact, many will be assigned to lower risk tiers or no longer be subject to CFATS regulation. In order to facilitate compliance with the CFATS program, DHS continues to offer a variety of assistance tools, including a help desk, Web-based tools and seminars, and on-site visits to all covered facilities.
