Dear Mr. Naasz:
This responds to an emailed inquiry from your organization concerning the applicability of the
security plan requirements in Subpart I of Part 172 of the Hazardous Materials Regulations
(HMR; 49 CFR Parts 171-180) to agricultural retailers. Specifically, you ask whether an
agricultural retailer is required to verify that a customer has a security plan.
The security plan requirements in Subpart I of Part 172 apply to persons who offer for
transportation or transport certain hazardous materials in commerce. An agricultural retailer
who sells agricultural products such as fertilizer or pesticides to a farmer is an offeror for
purposes of the HMR and, thus, must develop and implement a security plan if it sells
hazardous materials in the types and amounts listed in § 172.800(b). In accordance with
§ 172.802, the security plan must address personnel security, unauthorized access, and en route
security.
The regulations do not require an agricultural retailer to verify that its customers have a security
plan nor do the regulations require the retailer to collect or review customer security plans.
However, the retailer's security plan should indicate the measures it has taken to address en
-
route security. For example, an agricultural retailer may want to suggest to his customers that
they take certain precautions while transporting the hazardous materials from the retailer's
facility to the customer's facility. Such precautions could include: (1) to the extent practical,
minimizing transit time by going directly from the retailer to the destination; (2) to the extent
practical, preventing unauthorized persons from gaining access to the shipment by monitoring
the shipment during stops, locking the shipment inside the transport vehicle, securing the
shipment to the transport vehicle, and/or securing closures on the containers) or package(s);
and (3) reporting suspicious incidents or events to local law enforcement officials and/or the
Federal Bureau of Investigation.
The Research and Special Programs Administration has developed a fact sheet and a sample
security plan (copies enclosed) to assist farmers to comply with the security plan requirements
in Subpart I of Part 172. To address security issues associatec with the transportation of

products to the customer's facility, an agricultural retailer may want to provide the customer

PRODUCTION AGRICULTURAL OPERATIONS
Background
Farmers, ranchers and other agricultural operations can better secure the safe transport of
hazardous materials, deter terrorist and illegal acts involving hazardous materials, and reduce
their own exposure to liability by developing and implementing security plans that conform to
Department ot Iransportation (DOT) requirements in 49 CFR Part 172, Subpart I. Agricultural
operations commonly use many materials that are potential targets for terrorism and illegal
activities, including: explosives like dynamite or detonators; certain poisonous pesticides;
fertilizers like anhydrous ammonia and ammonium nitrate; and fuels like gasoline, diesel, and
propane.

To assist agricultural operations in assessing risk and transporting hazardous materials safely,
this sample security plan contains three important components - personnel security, unauthorized
access, and security while in transit. Most importantly, the plan conforms to DOT security
requirements (49 CFR Part 172, Subpart I) for persons who offer or transport hazardous
materials.
Assessing Your Risk
Explosion and Fire. Hazardous materials that are explosive, flammable or combustible can be
used to attack large groups of people, buildings and critical infrastructure. Examples include
explosives and bulk quantities of gasoline, diesel fuel, or propane. In addition, bulk quantities of
ammonium nitrate and ammonium nitrate fertilizers can be used to make explosives. For
agricultural operations transporting these hazardous materials, the greatest security risk is that a
shipment may be highjacked or stolen.
"Toxic by Inhalation" Hazards (TIH). TIH materials, either as gases or volatile liquids, can be
1

<<<PAGE 7>>>

used to attack people in confined spaces such as buildings or subways. Bulk quantities present
dangers to large areas and could affect a significant number of people. In agriculture, TIH
includes the fertilizer anhydrous ammonia. For farmers transporting TIH materials, the greatest
security risk is that a shipment may be highjacked or stolen or attacked while traveling in a
populated area.
Poisonous Liquids or Solids. Materials with oral toxicity (i.e., poisonous if consumed) can be
used to attack food or drinking water supplies. Also, liquids that are toxic via the inhalation of
their vapors can be used to attack groups of people indoors or outdoors. In agriculture, certain
pesticides are considered toxic and are labeled by DOT as "Poisons." For agricultural operations
transporting toxic/poisonous materials, the greatest security risk is that a shipment may be
highjacked or stolen or illegally released while traveling in a populated or vulnerable
infrastructure area.

transporting these listed hazardous materials from any supplier to this operation.
Personnel responsible for transporting the listed hazardous materials from any supplier to this
agricultural operation will be instructed on how to adhere to this security plan.
Unauthorized Access
If it is necessary to stop during transportation of the listed hazardous materials, authorized
personnel of this agricultural operation's (operation personnel) will to the extent practical prevent
