The Screening Threshold Quantity (STQ) refers to the specific amount of a chemical of interest that triggers a facility's requirement to complete and submit the Chemical Security Assessment Tool (CSAT) Top-Screen. This regulation is part of the Chemical Facility Anti-Terrorism Standards, which aim to enhance security measures at facilities that handle potentially hazardous chemicals.
The term Screening Threshold Quantity is primarily used within the context of chemical safety and security regulations. It is relevant in legal practices related to environmental law, public safety, and anti-terrorism efforts. Facilities that meet or exceed the STQ must comply with federal regulations, including submitting necessary assessments and implementing security measures. Users can manage compliance through legal templates available on platforms like US Legal Forms, which provide guidance on required procedures.
Here are a couple of examples of abatement:
For instance, a chemical manufacturing facility that stores more than the designated STQ of a hazardous chemical must complete a CSAT Top-Screen to assess its security risks and compliance needs. Another example (hypothetical) could be a small distribution center that, due to increased inventory, surpasses the STQ and must therefore implement additional security measures.
