Today the CISA Infrastructure Security Compliance Division (ISCD)
published two the Fact Sheets on their Chemical Facility Anti-Terrorism
Standards (CFATS) Knowledge Center.
They also revised a Frequently Asked Question (FAQ) and four responses to FAQs.
New Fact Sheets
ISCD published to new Fact Sheets as part of their outreach
program. The two
• Protect Chemicals at Warehouse, Storage, and Distribution
Facilities From Use in a Terrorist Attack
• CFATS: Top-Screens for Dynamic Business Operations
The warehouse fact sheet is part of the ISCD’s industry outreach
program; providing information about the CFATS program and how warehousing
facilities are affected by the program. This is very similar in concept and
information to previously published industry outreach fact sheets.
One small nit to pick with the information provided; the list of ‘common
chemicals of interest (COI) includes ‘anhydrous ammonia’; probably more commonly
found in warehouse operations would be ‘ammonia (concentration 20% or greater)’.
The dynamic business operations fact sheet is another look
at a topic that was discussed
here last week. The information provided in this new fact sheet is very
similar to the information provided in the relatively new CSAT Top Screen Submissions
Tips page.
Revised FAQ – Ammonium Nitrate
While ISCD has been revising a number of FAQs over the last
couple of months to make them more useful, every once-in-a-while they actually
change one of the questions being asked, which generally requires a significant
rewrite of the response. Such was the case today when FAQ #1228 was changed.
• Old question - How is the
Screening Threshold Quantity (STQ) calculated for Ammonium Nitrate (AN)?
• New question - How
is the screening threshold quantity (STQ) calculated for ammonium nitrate (AN)
[with more than 0.2 percent combustible substance, including any organic
substance calculated as carbon, to the exclusion of any other added substance]?
NOTE: The links provided for the FAQs in this post were
copied from the CFATS Knowledge Center but may not work when followed from your
machine. This is an artifact of that web site. If the links do not take you to
the referenced FAQ you will have to use the ‘Advanced Search’ function on the
page to link to the FAQ or download the ‘All FAQs’ document at the bottom of
the ‘Advanced Search’ page.
The difference is important because there are two different
listings for ‘ammonium nitrate’ in the list
of DHS Chemicals of Interest (COI); ammonium nitrate, the explosive (where
the ‘more than 0.2%... applies) and ammonium nitrate, the potential explosive
precursor. The original FAQ did not really distinguish between the two and this
made the Response a tad bit confusing. Instead of just taking the easy way out
and just revising the response to address the precursor form of the AN, ISCD
revised the question, expanded the answer and, in my opinion, just made the
matters more confusing, but then again AN is confusing.
AN, the fertilizer is the ‘non-explosive’ form of the
chemical. I know, Beirut and West, TX were big (big is a massive understatement
in the case of Beirut) explosions of AN. Perhaps ISCD should skip the two
listings (would take a rule change) for AN and treat both forms of the material
as an explosive for security purposes. It would still have the release-explosive
and theft/diversion security classifications and STQ’s, but it would clear up a
lot of the confusion. And let’s face it; a smart terrorist could craft an
attack on an ammonium nitrate fertilizer storage that would result in a massive
explosion.
Revised FAQ Responses
ISCD revised the responses for the following FAQ’s:
FAQ #1272 Who
is responsible for submitting a Top-Screen in situations where chemicals of
interest are located on property that is leased by a tenant from a landlord?
FAQ #1405 How
will I know if the agricultural extension has been lifted and what to do next?
FAQ #1456 Should
release chemicals of interest (COI) presently in process or chemicals that are
by-products be considered when calculating COI quantities toward the screening
threshold quantity (STQ)?
FAQ #1541 How
does a facility count the amount of a release-flammable mixture that is a fuel
with a National Fire Protection Association (NFPA) rating of 1, 2, 3, or 4 if
it is stored in an aboveground tank farm (including farms that are part of
pipeline systems)?
For the most part these changes were non-substantive changes
made for clarification purposes; no changes in policy or procedure were
included. The changes were:
#1272 Added a reference link and
additional explanatory language (2nd paragraph),
#1405 Changed URL to document link,
#1456 Removed reference to ‘total
onsite quantity (TOQ)’, and
#1541 Added comments about the gasoline
Top Screen extension (2nd paragraph).
