  • Unless siding is rated as Class 2 or higher, key
    train holds main track
  • Car must be equipped with roller bearings
  • If visual inspection cannot confirm a defect
    bearing reported by a wayside detector, train
    will not exceed 30 MPH until passing next
    detector or inspection
  • If second wayside detector confirms defect, car
    must be pulled off of train

    carloads or intermodal portable tank loads of
    hazmat, or a combination of 4,000 loads of
    PIH/TIH, AA, flammable gas, Class 1.1 or 1.2
    explosives, environmentally sensitive chemicals,
    SNF or HLRW in one year
  • Requirements
  • Wayside bearing detectors or equivalent
    technology no more than 40 miles apart
  • Main line track inspected by rail defect
    detection and track geometry cars or equivalent
    no less than 2 times/year sidings no less than
    once per year
  • Periodic inspections of main track and sidings
    for cracks or breaks in joint bars

    4 MPH
  • Loaded PIH/TIH, AA or flammable gas cars cut off
    in motion in no more than 2-car cuts

    security risk annual review required
  • Institute measures to address vulnerabilities and
    risk identified
  • Restrict distribution and access to data and

    information (SSI)

49 CFR Part 172 contains this requirement
15
Rail Hazmat Routing Regulations (HM-232)

    operations that could impact safety and security
    analyses every five years
  • Limitations on Actions by States

    not designate, limit or prohibit use of any rail
    line unless obtain waiver of preemption
  • Storage and Delays in Transit

17
Differences in Highway and Rail Routing of Hazmat
  • Private vs. public right-of-way
  • Fewer routing alternatives between any given
    origin-destination pair for rail
  • Larger quantities per container by rail
  • Train consists vs. individual trucks
  • Carrier interchanges by rail
  • Population proximity to right-of-way along route
  • Avoiding urban areas/center cities more difficult
    by rail

Source Battelle Memorial Institute
18
Different Approaches In Applying Routing Criteria
  • Require a route to pass across a segment that
    presents a low risk.
  • Require a route to avoid a segment that presents
    a high risk (i.e., hot spot).
  • Allow a route to use a high-risk segment, but
    impose a penalty (i.e., added cost) to any
    candidate route that would include that segment.

Community Activism
  • Communities located along major hazardous
    materials transport routes have long feared the
    possibility of a hazardous materials release.
  • There have been historic occurrences of such
    events with severe consequences (e.g.,
    Graniteville, SC).
  • Organized opposition has often formed to dissuade
    carriers from moving particularly dangerous
    hazardous cargo through a community (NIMBY not
    in my backyard).
  • Hazmat shippers and carriers are actively working
    with these communities to improve hazmat
    transport safety and security, through such
    initiatives as
  • TRANSCAER (Transportation Community Awareness and
    Emergency Response)
  • Participation in State Emergency Response
    Commissions (SERCs) and Local Emergency Planning
    Committees (LEPCs)
  • Hosting Capability Assessment Programs (CAPs)

22
Key Takeaways
  • Hazardous materials shippers select preferred
    modes based on the characteristics of the cargo
    and the ability of the mode to satisfy the
    desired transport requirements.
  • Hazmat route selection is heavily regulated for
    the truck and rail industry, in terms of
    designated routes and requiring route risk
    assessments that consider a variety of economic,
    safety, security and environmental factors.
  • Tradeoffs exist among routing options in terms of
    their ability to satisfy various criteria,
    leading shippers, carriers and regulators to
    identify preferred routes based on criteria
    importance.

23
Student Exercise
  • The table below presents the results of an
    analysis that was performed on six hazardous
    materials highway routing options.
  • Based on the information provided, which route
    would you select as the preferred option? Explain
    your method and show how it was applied in
    determining the preferred route.
  • Report back on your methodology during the next
    session for comparison with others to identify
    the most desirable method(s).

Route Option Trip Length (miles) Population Density (per sq. mile) Proximity to Iconic Targets Proximity to Enviro. Sensitive Areas Accident Likelihood Emergency Response Capability

2 33.2 6,600 High Medium Low Good
3 47.0 3,700 Low Low Medium Fair
4 19.5 15,900 Medium Medium High Excellent
