HAZARDOUS MATERIALS INFORMATION:
Hazardous materials regulations are applicable to farming operations. 49 CFR Part 173.5 and §42-
20-108.5 C.R.S., provide for certain exceptions to their applicability. Intrastate agricultural
operations are exempted from the requirements of the hazardous materials regulations, except for
gases, when transporting the agricultural product over local roads between fields of the same farm.
Gases that are transported over local roads between fields of the same farm are exempted from the
requirements for emergency response information and training.
49 CFR Part 173.5 provides limited exceptions from the regulations. The transportation of an
agriculture product to or from a farm, within 150 miles of a farm, is excepted from the requirements
of Emergency Response, Training and specific packaging requirements when:
a) It is transported by a farmer who is an intrastate private motor carrier;
b) The total amount of agriculture product being transported on a single vehicle does not exceed
i) 16,094 pounds of ammonium nitrate fertilizer properly classed as Division 5.1, PG III, in
a bulk packaging, or
ii) 502 gallons for liquids or gases, or 5,070 pounds for solids, of any other agricultural
products.
c) The movement and packaging of the agricultural product conform to the state requirements;
d) Each person having any responsibility for transporting the agricultural product or preparing
the agricultural product for the shipment has been instructed in the applicable requirements.
NURSE TANKS:
Nurse tanks are considered to be implements of husbandry when they are transporting anhydrous
ammonia and operated by a private carrier exclusively for agricultural purposes. They do not have to
meet the packaging requirements under 49 CFR Part 178. They do, however, have to meet the
requirements set forth within 49 CFR Part 173.315(m).
HAZARDOUS MATERIALS ROUTING:
Farm machinery which is exempted from registration requirements under §42-3-104(3) C.R.S.,
agricultural distribution equipment attached to or conveyed by such farm machinery, or vehicles used
to transport to or from a farm or ranch site products necessary for agricultural production are not
subject to the permitting and routing rules as adopted by the Colorado State Patrol. This does not
apply if these vehicles are used in the furtherance of any commercial enterprise other than
agriculture.
MATERIALS OF TRADE:
Under §42-20-108.5, C.R.S., the movement of hazardous materials, except for gases, is exempted
from the hazardous materials regulations when transported by an intrastate farmer over local roads
between fields of the same farm. 49 CFR Part 173.6 addresses other specific exemptions for
materials of trade.
