The Refrigerating Engineers & Technicians Association reports that the Department of Homeland Security (DHS) is increasing efforts to identify facilities regulated under the Chemical Facilities Anti-Terrorism Standards (CFATS) program. DHS has recently sent out a large number of letters to facilities regarding potential noncompliance with the CFATS program, identifying facilities that may not have filed a Top-Screen with DHS.
Notwithstanding certain exemptions, facilities with a chemical of interest, such as anhydrous ammonia, at a screening threshold quantity (10,000 lb for ammonia) must file a Top-Screen with DHS within 60 days of acquiring a threshold quantity of the chemical.
To learn more about the Top-Screen requirements, read the user guide from DHS here.
