Chemical Facility Anti-Terrorism Standards


State and federal governments have long regulated safety
practices at facilities that store large amounts of hazardous
chemicals to reduce the risk of harm from an accidental
release. In 2006, the Department of Homeland Security
Appropriations Act, 2007 (P.L. 109-295) authorized the
Department  of Homeland Security (DHS) to regulate
security practices at chemical facilities to reduce the risk of
terrorists triggering an intentional release or stealing
chemicals for use in attacks elsewhere. Subsequently,
Congress extended and modified this authority through the
Protecting and Securing Chemical Facilities from Terrorist
Attacks Act of 2014 (P.L. 113-254). This authority is
currently set to expire in April 2020.

Chemical Facility Anti-Terrorism
Standards
In 2007, DHS  promulgated the Chemical Facilities Anti-
Terrorism Standards (CFATS,  6 C.F.R. Part 27). These
regulations require certain high-risk chemical facilities to
meet risk-based performance standards in 18 areas (Table
1). The statute does not permit DHS to require any
particular security measure. Facilities may implement any
security program or process that adequately meets the
requisite performance level for its risk level.

Each covered facility must meet standards based on its
specific risk, i.e., higher risk facilities must meet more
stringent standards than lower risk facilities.

Table  I. CFATS  Risk-Based  Performance   Standards


*   Restrict Area
    Perimeter
*   Secure Site Assets
*   Screen and Control
    Access
*   Deter, Detect, and
    Delay
*   Shipping, Receipt, and
    Storage
*   Theft and Diversion
*   Sabotage
*   Cyber


Response


*   Monitoring
*   Training
*   Personnel Surety
*   Elevated Threats
*   Specific Threats,
    Vulnerabilities, or Risks
*   Reporting of Significant
    Security Incidents
*   Significant Security
    Incidents and Suspicious
    Activities
*   Officials and Organization

Covered   Facilities
Most chemical facilities do not have to meet these
standards. The statute specifically excludes all facilities
defined as a water system or waste water treatment works,
owned  or operated by the Department of Defense or
Department of Energy, regulated by the Nuclear Regulatory
Commission,  or regulated under the Maritime


Transportation Security Act of 2002 (P.L. 107-295). Any
non-excluded facility that possesses more than a defined
threshold of any of the 322 chemicals of interest (6
C.F.R. Part 27, Appendix A) must submit information to
DHS  through an online survey known as Top-Screen. DHS
uses Top-Screen data to determine each facility's risk level.
Only facilities DHS deems high risk must meet the risk-
based performance standards. As of December 2018,
approximately 40,000 unique facilities had submitted Top-
Screen data. DHS has determined that 3,355 (-8%) of these
are high-risk facilities.

DHS   assigns each high-risk facility to one of four graduated
risk tiers (Figure 1). About 5% of the high risk facilities are
in the highest tier, Tier 1.

Critical Infrastructure Protection: DHS Should Take Actions to Measure
Reduction in Chemical Facility Vulnerability and Share Information with First
Responders, GAO- 18-538, August 2018.
Each covered facility must prepare and submit a Security
Vulnerability Assessment that describes its vulnerability to
DHS-defined  attack scenarios and a Site Security Plan that
details how the facility will meet each of the 18 risk-based
performance standards appropriate for its risk tier.
Following evaluation of the Site Security Plan and an on-
site authorization inspection, DHS may issue a letter of
approval. The approved facilities must implement the Site
Security Plan and conduct annual implementation audits.
DHS  inspects each covered site every two years.
