Facilities that possesses any chemicals of interest (COI) listed in Appendix A at or above the specified screening threshold quantities (STQ) are considered chemical facilities of interest and must report their chemical holdings to the Cybersecurity and Infrastructure Security Agency (CISA) within 60 days by filing a Top-Screen survey.
The Top-Screen is an online, easy-to-use survey available through the Chemical Security Assessment Tool (CSAT).
CISA uses the Top-Screen information to determine if the facility presents a high level of security risk and is, therefore, subject to CFATS regulation.
Please note that if your facility comes into possession of additional COI listed on Appendix A at or above the STQ, or makes a material modification after submitting the Top-Screen, your facility must complete and submit an updated Top-Screen to CISA within 60 calendar days.
To begin the process of reporting your COI, visit the CFATS Process webpage.
How to submit a Top-Screen?
The Top-Screen survey is housed in CSAT—a secure, online portal used by covered chemical facilities and CISA to submit and receive CFATS-related applications and documents. CSAT is only accessible to Chemical-terrorism Vulnerability Information (CVI) certified individuals.
After completing CVI training, facilities should register for a CSAT user identification and password. CISA will validate a facility's registration and notify the facility on how to access CSAT.
Facilities can then log into CSAT and submit a Top-Screen survey to CISA for review.
Facilities Excluded from CFATS
Certain facilities are excluded from the CFATS regulation by statute if they are:
- Regulated by the Maritime Transportation Security Act
- A public water system, as defined in 42 U.S.C. § 300
- A treatment works, as defined in 33 U.S.C. § 1292
- Owned or operated by the Department of Defense or Department of Energy
- Subject to regulation by the Nuclear Regulatory Commission
An agricultural production facility that uses the COI on crops, feed, land, livestock, or poultry may also be granted an indefinite extension from reporting COI to CISA. Read more in Federal Register Vol. 73, No. 6, page 1640.
- Download a printer-friendly CFATS Agricultural Production Facilities fact sheet to understand the agricultural extension, and which facilities may be required to report their chemical holdings under CFATS.
The Transportation Security Administration is the lead component within the Department for regulating the security of transportation facilities such as railroads and natural gas pipelines. CISA does not currently require railroad facilities that possess COI that meet or exceed the STQ to complete a Top-Screen.
The CFATS regulation does require the reporting of COI that meet or exceed the STQ found within any rail car that is detached from motive power. However, if the COI is attached to motive power, the COI does not need to be reported. The regulation requires the reporting of threshold quantities of theft/diversion and sabotage COI within any rail car at the facility, whether or not the rail car is attached or detached from motive power.
Covered chemical facilities with a pipeline within their boundaries must also identify the pipeline as an asset and address it, as appropriate, in the facility's Security Vulnerability Assessment (SVA)/Site Security Plan (SSP).
Enhanced Tiering Methodology
In September 2016, CSAT 2.0 was released in conjunction with the CFATS enhanced tiering methodology to improve integration between surveys and to more appropriately identify and tier high-risk chemical facilities.
All chemical facilities of interest and CFATS-covered chemical facilities that previously submitted a Top-Screen to CISA had to resubmit a Top-Screen in CSAT 2.0 to be run through the new tiering engine.
In April of 2017, CISA began sending tiering determination letters to chemical facilities based on the new methodology. Tiering notifications continue as new Top-Screens are processed.
