What Is a Hazardous Material?
• Many organizations have offered definitions of the
synonymous terms “hazardous materials” and “dangerous
goods” to meet various needs (see handout):
– Institute of Hazardous Material Management (IHMM)
– National Fire Protection Association (NFPA)
– U.S. Department of Transportation (DOT)
– U.S. Environmental Protection Agency (EPA)
– U.S. Occupational Safety and Health Administration (OSHA)
– U.S. Nuclear Regulatory Commission (NRC)
– U.S. General Services Administration (GSA)

Basic USDOT Definition of Hazardous Material
4
A substance or material, that when transported in
commerce, is capable of posing an unreasonable risk
to:
– Health
– Safety
– Property

Dangerous Goods Are Internationally Regulated
• UN Recommendations on the Transport of Dangerous Goods
– Not obligatory, but form the basis of many national systems and
international agreements
• International Maritime Organization (IMO)
– International Maritime Dangerous Goods (IMDG) Code, part of the
International Convention for the Safety of Life at Sea
• Intergovernmental Organization for International Carriage by Rail
– International Carriage of Dangerous Goods by Rail, part of the Convention
concerning International Carriage by Rail.
• International Civil Aviation Organization (ICAO)
– Technical Instructions For The Safe Transport of Dangerous Goods by Air
• International Air Transport Association (IATA)
– IATA Dangerous Goods Regulations

Overview of Legal and Regulatory Process
• Federal Legislation
– Examples: Hazardous Material Transportation Act, National
Environmental Policy Act, Oil Pollution Act, laws in other spheres
• Regulatory Agencies
– DOT, EPA and at least 50 others
– Create and enforce rules - regulations - that carry the full force of law
• Federal Rulemaking Process
– The process of creating and enacting federal regulations is generally
referred to as the “rulemaking” process.
– Regulatory agencies create regulations according to rules and
processes defined by Administration Procedure Act.
– Agencies must publish all proposed new regulations in the Federal
Register at least 30 days before they take effect, and they must
provide a way for interested parties to comment, offer amendments,
or to object to the regulation.
• State and local governments have similar processes, but may not
enact laws and regulations that conflict with federal enactments.

The Federal Hazardous Materials Transportation Law
• 49 U.S.C. § 5101 et seq. is the basic statute regulating
hazardous materials transportation in the United States.
• Purpose: to “protect against the risks to life, property,
and the environment that are inherent in the
transportation of hazardous material in intrastate,
interstate, and foreign commerce” (emphasis added)
• Gives the Secretary of Transportation the authority to:
– Designate material as hazardous
– Issue regulations for the safe and secure transportation of
hazardous material

The USDOT Hazardous Materials Regulations (HMR)

packages from other cargo during flight.

Some Other Air Carrier Requirements
72
• Hazmat quantity limitations are found in the HMT, column 9.

Center for Disease Control (CDC).
– Some require a telephone report within 12 hours.
– All require a written report within 30 days.
• Radioactive materials – notify NRC within 12 hours
• Infectious substances – notify CDC within 12 hours
• Marine pollutants – notify NRC within 12 hours of
any release of:
– Solid greater than 400 Kg (882 lb)
– Liquid greater than 450 L (119 gal)

Other Reportable Incidents
77
• Telephone report required if any of the following occur:
– Death, or injury requiring hospitalization
– Change in flight pattern or routine of an aircraft
– Shutdown of major facility or transportation artery
– Evacuation of the public for one hour or more
– Any situation that involves a continuing danger to life
– On an aircraft, fire, rupture, explosion, or dangerous heat evolution
resulting from a battery or battery-powered device
• Written report on DOT Form F 5800.1 is required within 30
days following all telephone reports, and in general for any
release of a hazardous waste, or any other hazmat releases of
at least 20 liters (5.2 gal) for liquids or 20 Kg (66 lb) for solids.
– See 49 CFR §171.15-16 for detailed requirements.

PHMSA Hazmat Enforcement
78

• Emergency response

Hazmat Enforcement: Other Agencies
79
Enforcement authority under the federal hazmat law is shared by
PHMSA, FMCSA, FRA, FAA, and USCG.
• FMCSA - the transportation or shipment of hazardous materials by highway.
FMCSA also enforces the Federal Motor Carrier Safety Regulations (49 CFR
Parts 350-399).
• FRA - the transportation or shipment of hazardous materials by railroad. FRA
also enforces the rail safety regulations (49 CFR 200-268).
• FAA - the transportation or shipment of hazardous materials by air. FAA also
enforces all regulations applicable to air carriers and shippers by air issued
under the Federal Aviation Act.
• USCG - the transportation or shipment of hazardous materials by water. USCG
also enforces its own regulations governing the bulk transportation of
hazardous materials by vessel, and regulations issued under other laws, such
as the Federal Water Pollution Control Act and the Comprehensive
Environmental Response, Compensation and Liability Act.
In addition, EPA enforces environmental regulations related to
hazardous wastes and substances, and marine pollutants.

Penalties for Violating HMR
Violations of the HMR may result in
• Civil penalties of $250 to $110,000
– Minimum $495 for training related violation
– Each day of a continuing violation is a separate offense
• Criminal penalties of up to $250,000 (individuals) and
$500,000 (corporations), plus up to ten years in prison
Note: MAP-21 includes language changing some of the penalties, so the
regulations will be changing to incorporate the new minimums and
maximums.

Other Regulatory Requirements, Standards, and
Guidelines
81
• DOD Military shipments
• DOE/NRC Nuclear materials
• STB Commercial transportation
• OSHA Worker health and safety
• NLRB Organized labor
• NFPA First responder safety and health
• USDA Invasive species
• State-level hazmat compliance programs

Issues Involving Multiple/Overlapping Regulations
82
• The federal hazmat law and the HMR provide that, unless
authorized by another Federal law, a requirement of a state,
local government, or Indian tribe is preempted if:
– Compliance with both laws/regulations is not possible.
– The non-federal requirement interferes with carrying out the federal
law or HMR.
– The State, local, or Indian tribe requirement concerns a “covered
subject,” and is NOT “substantively the same” as any provision of, the
Federal hazmat law/regulation concerning that subject.
– The “covered subjects” are those covered in the main provisions of the
HMR, e.g., hazmat identification and classification, shipping papers,
marking, labeling, packaging, etc.
• State and Indian tribe highway routing designations,
limitations and requirements relating to hazardous materials
will be preempted unless they meet federal procedural and
substantive requirements.
