Steps Toward DHS Compliance – Chemical Facility Anti-Terrorism Standard
Department of Homeland Security (DHS) released the final DHS Chemicals of Interest Appendix A to the Chemical Facility Anti-Terrorism standards. Whereas Appendix A was released on Nov. 2, it did not go into effect until it was published in the Federal Register on November 20, 2007 (FR# 223). This means the 60-day deadline to complete DHS’s “Top Screen” did not begin until this FR publication date.
Major changes to the final version of Appendix A are detailed below.
- Mixtures – The issue of mixtures was resolved. The list contains maximum concentration percentages, commercial grade designation or a placarded amount. Many are set at a minimum concentration of 1 percent, so SDSs for commercial products will have to be checked.
- Any amount – The designation of “any amount” has been replaced by actual amounts.
- Screening Threshold Quantities (STQ) – STQs have increased for many compounds.
- Propane – The STQ for propane is 60,000 pounds (not counting propane in containers of 10,000 pounds or less) where it had been 7,500 pounds on the originally proposed list.
- No longer on the list – Carbon monoxide, acetone and urea are no longer listed.
The initial step to comply with the new DHS regulation is registration, which is completed online. At the end of the registration, the submitter will learn if proceeding to the Top Screen will be required. If not, the submitter is done after the registration is complete. Upon completion of Top Screen, DHS will let the facility know within 30 days if it is a Tier 1, 2, 3, or 4 level facility.

The Top Screen is divided into the following chemical categories:
- Release of Toxins
- Release of Flammables
- Release of Explosives
- Theft/Diversion of IED Precursor Chemicals
- Theft/Diversion of Weapons of Mass Effect (WME)Theft/Diversion of Chemical Weapons/Chemical Weapon Precursors, and Sabotage/Contamination Chemicals (e.g., things that can react with water to produce hydrogen cyanides).
Note: there maybe different STQs for different categories.
Another category is “Mission Critical” chemicals, which do not appear in a list. These chemical are tied to manufacturers responsible for production of 20% or more of any one chemical necessary for one or more critical infrastructure sector (defense, energy, public health, public water) and will require a facility to make a “best estimate” to determine if it falls in this category. DHS wants to know where the bottlenecks exist in the system that could affect its ability to protect the country.
Top Screen links each chemical name to information about how to count that chemical and that basis for the chemical’s listing. All amounts have to be counted when determining threshold quantities – in tanks, vessels, pipes, trucks parked in driveways, etc. Any amount “possessed” at any time for the previous 12 months must be counted.
Each facility will need to determine how the definition of “facility” applies to it and DHS will either agree or disagree with the submitter. DHS advises to define a facility as it is managed under each corporation. There may be penalties if an owner/operator attempts to break up a facility to avoid “possessing” threshold quantities of Appendix A chemicals.

What Clients Are Saying
After researching other SDS-managing software systems, SDSpro offered the easiest, most efficient, and comprehensive managing system and was much more reasonable in price. Not only am I more than satisfied with the software, but the people have been accessible, helpful, and friendly. When I purchased SDSpro, I also bought into a team who cared about my success.
The Onsite Chemical Inventory Assessment Service is highly functional, technologically advanced and consistently exceeds our expectations! Their inventory team carefully executed physical and chemical audits to ensure we meet OSHA’s Right-to-Know Act in a cost-effective and efficient manner. We highly recommend SDSpro.
The SDSpro team was extremely helpful, professional and knowledgeable (along with being very positive and cheerful) in their field. I can only say great things about this team and their completion of this particular task and would highly recommend them to anyone who is looking for a chemical audit solution.
Our experience with the MSDSpro software to date has been great. MSDSpro is user friendly, especially for the end users, and provides us an excellent vehicle for MSDS management. We have received excellent technical support from MSDSpro, and would recommend this product to anyone considering MSDS management software.
Once I saw your program, I told the other team members that this was the product to use, hands-down. Installation only took thirty minutes, as opposed to almost two hours for the others. Your program is also the only one that we came across that allowed us to use any type of scanner to import our own MSDS sheets. I think you have an awesome product.
Northwest Aluminum Company has evaluated over 10 competitive MSDS packages. We found that MSDSpro has everything we needed, it was easy to train users and the Enterprise networking solution is the easiest to implement that we have found. It doesn’t take a computer “geek” or rocket scientist to implement MSDSpro. We are very satisfied.
SDSpro’s customer focus is evident and present throughout the entire process – from initial concept and sales discussions to implementation meetings, data entry, training and tech support have all been great. When help and support is needed, I am always sure to get a quick and effective response.
My positive experience with SDSpro can be summed up by the word “simplicity”. The program is easy to setup, utilize, and pull information from. We use a LAN and the SDSpro software works seamlessly producing high quality documents.
I can tell you that having the MDC/scanner is a blessing! For what it is designed for, in general, the MDC/Laser Barcode Scanner is a great tool to have. The device is user-friendly (simple to use), handy (not bulky), it has great storage capability, a time-saving device etc. I highly recommend this product!
