DHS Tiering Methodology

Today, the Infrastructure Security Compliance Division of DHS hosted a webinar on their new tiering methodology for CFATS facilities.

The presenters stated that the increases and decreases of theft/diversion and release-toxic chemicals of interest (COI) is due to improvements and implementation modeling data available to DHS. Facilities that possess Triethanolamine and MDEA, for example, will most likely be increased to Tier Two for theft/diversion chemical weapon precursor due to the implementation of the new modeling tools.

DHS began sending out letters to facilities earlier this month based on the new tiering methodology. Facilities are instructed to review their SSP/ASP to ensure that the existing security measures are sufficient for the tier level. If a facility determines that they need to resubmit their SSP/ASP, the facility has 30 days from the date of the letter to update the Security Vulnerability Assessment and Security Plan. Note: This deadline is not mentioned in the letters that our clients have received.

 During Compliance Inspections, inspectors will verify that the security measures are appropriate to address all tiers, security issues and COI.
