HAZARDS ANALYSIS
ON THE MOVE
Between 1987 and 1989,U.S.
Department of Transportation
(DOT) officials reported
almost 60,000 transportation incidents
that resulted in an unintentional release
of hazardous materials. How can you
assess the transportation risks facing
your community? Is your community
prepared to face these risks'?
The purpose of this document is to
help you as local planners (e.g., tribal
and state LEPCs, and other planners)
and responders, develop a method to
determine what hazardous materials
are being transported through your
community and the priority areas of

risk that warrant further analysis and
study. By doing so, you can assess and
improve existing strategies to
minimize risk (both public and private)
and the response capabilities within
your jurisdiction.

In the Emergency Planning and
Community Right-to-Know Act
(EPCRA), Congress recognized the
risk to communities posed by the
transportation of hazardous materials
and required that emergency response
plans developed by LEPCs identify the
"routes likely to be used for the
transportation of substances on the list
of extremely hazardous substances...."
One way to approach this requirement.
and to address all of the hazardous
materials being transported through
your community, is to conduct a
hazardous materials commodity flow
study (CFS). A CFS is an assessment
of the types and volumes of materials
moving through your community.
For some communities, especially
those in rural areas, transportation may
pose the only hazardous materials risk.
In light of the number of accidents that
occur (see chart at left), identifying and
understanding transportation-related
risks are critical components of
emergency preparedness and
prevention. The goal of the CFS is to
use the information collected to
increase your preparedness,
prevention, and response capabilities.

What are the objectives.
A CFS is the hazards identification
step of transportation hazards analysis,
described in Technical Guidance for
Hazards Analysis, an EPA, DOT,
FEMA publication (see page 7). A
CFS is the collection of existing and
new data on transportation patterns in
your jurisdiction. Combined with
accident histories, geography, and
other local conditions, a CFS will help
you characterize hazardous materials
transport, identify locations of risk and
other vulnerable areas, and formulate
emergency planning, prevention, and
response measures. Some specific
objectives of performing the CFS are:
Identify major hazardous materials
traffic corridors:
Characterize types of substances,
shipment frequencies, container
types, and container capacities;
Specify the location, length, and
nature of priority highways, rail
(continued on next page)
Lessons Learned
The National Institute for Chemical Studies (NICS) is in the process of conducting a CFS as part of a comprehensive hazards analysis
in the Kanawha Valley region of West Virginia an area with a very high concentration of chemical facilities. NICS is characterizing
hazardous materials transportation and the potential risk it presents in order to improve emergency response plans in the vulnerable areas
of the region. A specific goal of the NICS study is to develop lessons learned for other communities that might conduct a CFS. How
can NICS' experience help your CFS? Although the study is not yet complete, several helpful suggestions can be made from the work
completed to date. There are several points to keep in mind.
The effort put into a CFS should match the community's goals and its resources. In some cases, a great deal of detail or expense may
not be needed for useful emergency planning. NICS' CFS indicates that there are many different types of hazardous materials being
transported through the study area. In othercommunities, hazardous materials transportation may be dominated by a few specific classes
of chemicals, such as flammables or corrosive liquids. In these cases, focused hazards analysis and emergency planning efforts may
be possible by addressing each of these classes, rather than all of the individual chemicals in each class. A CFS, however, could show
that specific hazardous materials, such as spent nuclear rods or military munitions, are transported infrequently through the community,
but pose enough hazard to warrant special attention from emergency planners. Other helpful hints from the NICS study include:
0 Hazardous materials transportation can vary by the time of day and the day of the week. Be sure to account for this when planning
field surveys.
0 Questionnaires mailed to facilities will often require follow-up telephone calls for clarification and to improve the rate of response
0 A CFS that includes many field observation efforts, such as placard or waybill surveys; can generate large quantities of data -
computerized data management may be needed or you may wish to scale back the focus of your study.
Q Effective training and supervision of field survey personnel will improve the quality of the observations and data collected.
0 Shipping papers are often in many different formats. Decide what data you will need and develop a standardized table for entering
the information.
Q Police and other emergency responders can identify highways and intersections where accidents have occurred in the past to guide
data gathering and hazards analysis efforts.
^ Incorporate the results of other data gathering efforts. For example, total traffic volume figures developed by transportation
agencies can be used to estimate the percentage of vehicles carrying hazardous materials over a given route. These figures can
help you address planning issues such as the potential exposure to drivers should a hazmat accident occur during peak travel times.
0 Access existing databases and inventories, such as those developed by railroad companies and district offices of the Army Corps
of Engineers.
A final guidance document based on the NICS study will he developed upon completion. Contact Dr. Jan Taylor or Dr. Paul Hill at (304)

tracks, and other routes (paying
special attention to those that pass
through or along densely
populated or sensitive
environmental areas);
• Characterize any local terminals or
other gathering areas for
hazardous materials transport
vehicles such as truck stops and
weigh stations; and
• Compile data on any travel and
route restrictions in effect for the
region.
Many communities have conducted
CFSs that identify the types, amounts,
and routes of hazardous materials
being transported in and through their
region. You can leam from their
experiences, several of which are
discussed throughout this document.
You will see that conducting a CFS
involves some methods different from
those used for hazards identification at
your fixed facilities. Instead of
referring to information on
conventional facility reports such as
Material Safely Data Sheets or Tier II
Reports, you will need to collect data
that may or may not be readily
available from public or private
sources. You must account for
different modes of transportation (e.g.,
railways, highways, pipelines,
waterways), and develop an estimate of
A New Funding Opportunity: Utilizing HMTA
Section 17 of the Hazardous Materials Transportation Act (HMTA) provides
funds to states to enhance the consideration of transportation-related risks in
current chemical emergency planning efforts, and to support the implementation
of EPCRA. (There is also an HMTA training grants program, available to both
states and tribes.) Conducting a commodity flow study is one of the activities
identified by Congress as eligible for funding under the HMTA planning grants
program, and could lead to other HMTA activities such as assessing local
responsecapabilities, improving the comprehensive emergency plans required
under EPCRA, and assessing the need for regional hazmat teams.
LEPCs should contact the agency selected by their Governor as the "designated
agency" for implementation of the HMTA program to leam more about
developing a proposal for receiving grant funds under the new law. Call the
U.S. DOT HMTA Grants Manager at (202) 366-0001 if you are unsure as to
which state agency has been selected to head the effort. Because of HMTA,
the, number of commodity flow studies conducted will increase. Keep an eye
out for other communities in your area who receive these funds so that you can
leam from their experiences as well.
the types and amounts of hazardous
materials being transported in and
through your region.
Our discussion begins by presenting
tips for getting organized, looks at
methods for gathering the necessary
data, and then examines the ways in
which you can apply the results of a
CFS. Finally, we consider some
technological and legislative changes
that may be of help to your
transportation planning efforts. 9
Getting Organized
Who needs to be involved?
As an LEPC, you may wish to form a
separate transportation hazards
advisory committee to lead the effort,
or the LEPC as a whole may take the
lead role. Whether or not you are able
to form a committee that meets
regularly, the LEPC should identify
state and local professionals to assist in
identifying sources of information and
to review drafts.
To cultivate broad-based support, an
advisory committee should reflect local
conditions and include representatives
from the LEPC, local planning
(continued on next page)

Getting Organized
(continued from previous page)
councils, the public works department
the State Department of
Transportation, the U.S. Coast Guard,
airport and port authorities, industry,
police and fire departments, and the
SERC.
Once the advisory committee has been
formed, it must formulate a workplan
for the study itself. In developing this
workplan, the advisory committee
should take the time to determine
specific objectives, what data are
available, and what data are needed in
order to accomplish the goals of the
CFS quickly and efficiently. This will
give the CFS a clear focus and give the
committee a better idea of what
resources will be necessary to
complete the study. Throughout this
document different methods are
suggested. You should evaluate your
needs against available resources,
and modify your approach
accordingly.
Don't re-invent the wheel!
Several agencies at the national and
state level compile some of the data
that you will need. The advisory
committee should identify these
agencies and determine what data
already exist. This is why having a
broad-based advisory committee is so
important. Everyone, especially the
state DOT representative, will have
access to different and valuable
information. Industry associations
such as the Chemical Manufacturers
Association, the Association of
American Railroads, the American
Trucking Association, and others may
have already collected and analyzed
additional data.
Nearby municipalities may have
already completed a CFS or may want
to join forces and combine resources.
For example, LEPC representatives
from Alexandria. Virginia, serve on a
multi-jurisdictional task force that is an
important forum for addressing
resource-sharing issues and is
developing a transportation hazards-
based emergency response plan. The
task force is devising a set of response
procedures, but is also working to
reduce the amount of hazardous
materials transported through, and the
number of accidents in, the region.
You can also integrate your CFS data
collection efforts with other on-going
data collection or inspection programs.
Once again, Alexandria, Virginia,
provides an example of effective inter-
agency coordination in its policy of
using fire department Title III Facility
Data Sheets to highlight likely
transportation routes for carriers of
extremely hazardous substances. The
LEPC incorporates this information on
transportation routes and chemicals
transported into its emergency
planning process to better respond to
transportation incidents.
Recruiting outside help.
Using volunteer personnel, students,
and local environmental groups can be
a great cost and time saver for the
LEPC. The Hancock County, Ohio,
LEPC took advantage of an innovative
program in environmental and
hazardous materials management at a
nearby university to obtain qualified
volunteers for its study on hazardous
materials transportation on the
county's highways. Following initial
training sessions, a total of 37 students
from the University of Findlay's
"Hazmat Club" were assigned survey
times and locations to conduct placard
surveys. Their assistance proved to be
an important tune saver for the LEPC.
A prison inmate volunteering for the
Butler County, Kansas, health office,
developed and implemented the
county's emergency response plan,
which included identification of the
transportation-related hazards in the
county. He spent over 800 hours
working on the plan and aiding other
counties in developing their plans. He
recommends the use not only of
inmates, but also senior citizens, who
possess the necessary time and
knowledge of the region to assist in
CFS efforts. Industry is another
(perhaps more traditional) potential
resource - local industry might be
persuaded to contribute personnel and
equipment to the study. •
-------
SARA TITLE III (EPCRA) AND CONDUCTING A COMMODITY FLOW STUDY
Gathering the Data
What 's the big picture ?
Begin by identifying the major
hazardous materials transportation
patterns: determine the general types of
hazardous materials moving
throughout the community, how they
are moved, and when they are moved.
A CFS doesn't have to provide a lot
of detail to be useful - given budget
constraints, collecting exhaustive
data on every chemical and every
mode of transportation will be
nearly impossible to accomplish.
Complicated risk analyses using
intricate mathematical formulas are
probably not necessary. Rough
estimates of hazardous materials traffic
can provide valuable information in
determining where risk lies.
Priority risk areas can be found at the
points of origin or destination of
hazardous materials, as well as at
intermediate locations. For most areas,
data for one month, or even one week,
may prove sufficient to project the
year-round flow of hazardous
materials. You can focus on general
classes of chemicals (e.g., flammables,
corrosives), unless you know that large
quantities of specific chemicals are
manufactured or stored in the area.
Some areas will experience seasonal
changes (e.g., a rural community may
experience an increased flow of
fertilizers and pesticides during a
portion of the year) that should be
evaluated separately from typical
flows. Seasonal patterns may be easy
to determine for local industry, but
keep in mind that such pat terns will be
extremely difficult to track for
interstate traffic. You should weigh
the costs and benefits of studying
seasonal transportation patterns in your
area.
Your next step.
Reviewing all of your facilities' Tier
II reports and the amount of
hazardous chemicals they store,
handle, or use annually will give you
an idea of the quantity and type of
materials transported through your
jurisdiction. A fixed facility
representative may be able to provide
you with a rough estimate of the types
and quantities of materials transported
through these facilities, or you may
decide to prepare a facility
questionnaire.
NICS prepared a comprehensive fixed
facility survey as a starting point for its
hazardous materials transportation
survey. NICS asked fixed facilities
about specific trends in the amount of
hazardous chemicals shipped over the
past few years, the exact mode of
transport, and the usual hours and days
of the week for shipping and receiving.
Facilities were asked to list the major
carriers for each chemical and the most
frequent origins and destinations of
loads. This information provided data
on the actual amounts and types of
hazardous materials shipped from or
received by facilities in the region. It
provided valuable information on the
general routes utilized by these
facilities and yielded transportation
data which could be compared to data
obtained by the field surveys. See
page 6 for the specific steps taken by
the Taylor County, Wisconsin
LEPC.
There are transportation depots that
are not necessarily captured under the
fixed facility definition in EPCRA, yet
hazardous materials are channeled
through them every day. Make sure
that your CFS includes truck
terminals, seaports, airports and rail
yards. Such depots may also warrant
study in the CFS because of the
potentially diverse types and amounts
of substances that are distributed from
them. Many of these facilities
voluntarily participate in the planning
efforts of the communities in which
they are located. If you feel more
formal mechanisms are needed,
however, there are provisions of
EPCRA that can help.
Section 302(b)(2) of EPCRA
authorizes the Governor and/or the
SERC to designate "additional
facilities which shall be subject to the
requirements of [section 302]...."
Railyards, sea ports, and airports are
examples of transportation depots that
can be included under section 302.
You should review your state and local
ordinances for provisions (similar to
EPCRA section 303(d)(3)) that provide
access to the information you need to
adequately address the transportation-
related risks facing your community.

HAZARDS ANALYSIS ON THE MOVE
On a Shoe-String Budget — Collecting the Data
Taylor County, Wisconsin, is a primarily rural community, with a small city and several villages. There are three state highways,
one railway, one small airport, and two pipelines within the county. The Taylor County, Wisconsin LEPC conducted a CFS and
transporation hazards analysis using the steps outlined below. You might find them useful when setting out to collect data for your
community. As Taylor County learned, conducting a CFS is a time-consuming process, but certainly manageable once priorities
have been set. By working on the project as time allowed, Taylor County was able to keep the total costs down. Over the course
of twelve months, two people worked a total of approximately 450 - 500 man hours. For more information on the Taylor county
study, contact Mr. Donald Albers, Community Emergency Coordinator, at (715) 748-3503.
1
Identify HAZMAT Routes
Taylor County started by pulling out local maps to determine which routes warranted study. You
can use state highway maps, county aeronautical charts, and municipal street maps to name a few.
Remember that pipelines might not appear on a map, but need to be included in your CFS. Taylor County
contacted pipeline companies directly, after obtaining contact information from the County Emergency
Government Office and the State Office for Emergency Preparedness.
2
Determine What HAZMATs Are Carried on Each of These Routes
Taylor County used the following methods to determine hazmat traffic volume and flow.
Route:
HIGHWAYS
RAILROADS
PIPELINES
AIRPORTS
Method of Determining HAZMATs:
0 Sent questionnaires/surveys to trucking companies, weigh stations, and known hazmat
suppliers/users;
0 Determined data collection points (priority/high-risk points); and
0 Performed traffic counts (placard survey).
0 Contacted the local representative from railway companies;
0 Researched waybills and manifests; and
0 Contacted the District Office of the Federal Railroad Administration in your area.
0 Contacted local pipeline companies; and
0 Contacted local utility commission for permitting records and "digsafe" programs.
0 Contacted airport managers to determine which airlines carry hazmats; and
0 Contacted local representatives for each airline identified.
There are no navigable waters within Taylor County. The LEPC suggests, however, that you contact shipping companies
and the district offices of the U.S. Coast Guard and the Army Corps of Engineers to obtain information on the hazardous
materials transported through your jurisdiction via waterways. (Check your phone book for local listings.)
3
Compile Accident Records
Finally, Taylor County examined accident histories to identify any recurring problems or severe
risks in the area. The following agencies can assist you in collecting information on your area's accident history:
State Department of Transportation
Police Department
Local hospitals and physicians
News media
State Emergency Management Agency
Public Health Department
Local industry

HAZARDS ANALYSTS ON THE MOVE
Gathering the Data
(continued from page 5)
Other facilities that can generate
substantial highway hazardous
materials traffic include oil-fired, coal,
and nuclear power plants; large
manufacturing facilities; agricultural
warehouses; waste management
companies: and public facilities. Keep
in mind that the lack of standardized
shipping manifests, not to mention
receiving them in different languages+
will complicate your analysis.
Your area's accident history is
another key starting point for
information. Federal and state
agencies compile accident data that can
be used to get a sense of what and
where the priority points are and what
kind of accidents your community
typically faces. You can use this
information, along with your
knowledge of local conditions, to help
identify high-risk areas.
The U.S. Department of Transportation
Hazardous Materials Information
System (HMIS) contains a variety of
data regarding the transportation of
hazardous materials by air, highway,
rail, and water. HMIS also contains a
data base on shipping routes for high
level radioactive materials that may be
of interest in assessing your
transportation-related hazards. The
HMIS Incident Report Data Base is
composed of carrier-reported
accidental release data from 1971 to
the present, as required by the Code of
Federal Regulations (49 CFR Part
171). The incident data include the
date of incident, chemical(s) involved,
quantity, location and land-use, cause
of release, mode of transportation, and
other information. The information
box on page 11 lists the DOT address
and telephone number for receiving
information on HMIS reports.
Addressing Your Additional
Data Needs
Once you have tracked down existing
information, how do you obtain the
data that are missing? Again,
assembling the proper team is crucial.
A data collection team may be
composed of members of the advisory
committee; or, if resources allow, it
might be wise to develop an "outside"
team. Whether it is made up of private
organizations, volunteers from
environmental groups and local
universities, or contractors, the data
collection team should receive a clear
mission, adequate training, a timetable,
and responsibilities from the advisory
committee.
Commodity flow studies commonly
involve a road-side placard survey.
These surveys identify what materials
are being transported and also give you
an idea of the quantity involved.
Usually, these surveys last for a few
days or weeks - observers note the
number of trucks that pass by, their
placards, the time, and the type of
container used. Although a great deal
of effort may be needed to make such a
survey statistically accurate, even a
modest program of field observation
can form a solid foundation for
conducting a transportation hazards
analysis.
The table on page 9 describes this and
other collection methods that have
been used in the past by communities
identifying transportation-related risk.
These methods can be adapted to local
conditions and specific modes of
transportation. The resources
identified on page 7 can help you
determine which methods are
appropriate for your study. Whatever
method you choose, the advisory
committee should organize the raw
data that have been collected into a
form that is conducive to continuing
analysis. •
What to Do With the
Results
Improving response; preventing
accidents
Many communities have conducted
hazards analyses to develop and revise
emergency response plans based on the
specific hazards found at fixed
facilities within their jurisdiction. The
hazards analysis process can also be
applied to transportation-related risk.
The Technical Guidance for Hazards
Analysis ("Green Book") describes the
hazards analysis process in detail. It
can be summarized in three basic steps:
• Hazards identification pinpoints
the location, quantity, storage
conditions, and the specific
(continued on next page)
-------
SARA TITLE III (EPCRA) AND CONDUCTING A COMMODITY FLOW STUDY
What to Do With the Results
(continued from previous page)
hazards posed by the hazardous
chemicals transported,
manufactured, stored, processed,
and used in the community.
• Vulnerability analysis locates
geographical areas and the people,
property, services, and natural
areas that may be affected by a
release.
Risk analysis provides a basis for
LEPCs to rank specific release
scenarios or locations based on the
likelihood and severity of the
release. The hazards analysis
method described in the Handbook
of Chemical Hazard Analysis
Procedures ("Brown Book")
separates this step into two steps,
consequence analysis and risk
analysis. The additional step is
simply an elaboration of the
process explained in me Green
Book.
A commodity flow study is, in effect,
the hazards identification step of the
hazards analysis process conducted for
transportation-related hazards. Once
the CFS has been completed, you will
have a good sense of what major
categories of hazardous materials are
transported through your region and
what the priority areas are - you will
have identified the transportation
hazards facing your community.

HAZARDS ANALYSIS ON THE MOVE
What to Do With the Results
(continued from previous page)
provide a picture of where the
hazardous materials are and which are
the major routes of concern for
planning purposes.
You can use the vulnerability and risk
analysis steps described in the Green
Book to translate the results of the CFS
into recommendations for revising
your emergency response plan and
determining your community's
specific preparedness, prevention, and
response needs. This evaluation will
help answer important planning
questions such as:
0 Just how vulnerable is your
community to these risks?
0 How can risks be reduced?
0 How can accidents be prevented?
0 What special populations (e.g..
schools, hospitals) are located
near these priority routes?
0 Are any of these routes marked by
significant congestion at certain
times of the day?
0 What is the response time of the
closest hazardous materials team?
0 How accessible is the area to
emergency vehicles?
0 What is a realistic scenario, given
the risks and probabilities ?
Once the remaining steps in the
hazards analysis process have been
completed, you can then turn to
assessing your level of preparedness
and revising your emergency response
plan to reflect the highest
transportation-related risks. Depending
on your circumstances, you may not be
able to tailor your emergency response
plan to focus on specific chemicals or
routes.
Just as with fixed facility planning,
budget constraints come into play as
the number of chemicals and hazards
increase. It is important, however, that
your plan addresses the risks that you
have identified to the best of your
ability. For example, if you discovered
that the local railroad terminal stores
hazardous materials cars in special
holding areas, obtain a map of the
facility, mark the holding areas, and
attach it to your emergency response
plan: then work with the railyard to
reduce the risks. Another example is
segregating incompatible cargoes and
establishing buffer zones between
holding areas and nearby communities.
After developing a realistic picture of
the hazards that your community faces,
you can begin to re-evaluate your
community's prevention strategies.
Are current measures appropriate?
Would traffic control on priority routes
make a difference'? Do accident
records suggest a need for driver safely
training'? Would commodity flow
restrictions during severe weather
alerts make sense? Be sure to identify
all of your community's prevention
concerns so you can ask the "right"
questions.
The CFS may also point to a need for
additional resources to increase the
community's level of preparedness (e.g.,
training, equipment, and on-going
planning). Again, it is most important to
have general response capabilities, rather
than trying to address every specific
chemical and/or transport route. •
Looking Ahead
Transportation-related risks are
continually changing, and to meet the
challenges that these hazards present, it is
important to look forward. With
construction of new highways, changes in
the composition of local industry, and the
enactment of new federal, state, and local
laws, there may be a change in the flow of
hazardous shipments through your
community. The commodity flow study
should not "sit on a shelf:" it should be
updated periodically and the community
emergency response plan revised
accordingly.
It is important to keep abreast of new
tools (both technological and legislative)
that are being developed and refined to
address many of the problems you may be
facing. Keeping these and other factors in
mind will help you with long-term
planning and future updates of the CFS
and the overall emergency response plan
Let's look at a couple of these
innovations and see how they might be
applied to your needs.

Metropolitan Planning
Organizations (MPOs)
Section 134 of the Intermodal Surface
Transportation Efficiency Act of 1991
(ISTEA) calls for me designation of an
MPO for each urbanized area of
greater than 50,000 people. The
primary responsibility of these MPOs
is to conduct the transportation
planning process for the area that it
covers. This process will include
developing transportation plans and
programs to promote comprehensive
solutions to regional problems.
MPOs represent a potentially
invaluable resource for your LEPC
when preparing a CFS. They will
have data and expertise that will make
your task easier, and they may even
be able to provide access to
equipment and techniques, such as
transportation-specific Geographic
Information Systems (GIS), that will
simplify the work and enhance the
form of your final product. Keep in
mind that the MPOs will be working
closely with state and local
transportation authorities, so that they
will likely have information for your
area.
Intelligent Vehicle/Highway Systems
(IVHS)
IVHS are a family of technologies that
are presently being developed to
improve transportation safely and
efficiency. By bringing high-tech
solutions in the form of advanced
computers, sensors, and communication
systems to some of the complex
transportation problems that confront
us, IVHS holds the promise of
mitigating congestion, enhancing
safety, promoting economic
productivity, and minimizing
environmental hazards.

HAZARDS ANALYSIS
Looking Ahead
(continued from previous page)
"Great," you might say, "but how will
this sci-fi stuff help me?" In the near
future, trucks and trains traveling
through your community could be
carrying electronic equipment that
identifies the cargo, keeps track of the
vehicle's location, and even projects
the intended route through your
district. Shipments of hazardous
materials could be tracked in "real-
time" by a traffic control center, and
sensors on the vehicle itself will be
constantly monitoring the condition of
the cargo.
Currently, there are over 20 operational
programs in the U.S. testing various
elements of IVHS, including those
directly applicable to hazardous
ON THE MOVE
materials transport. Remember that
transportation planning is an evolving
discipline, and that new tools are
constantly being developed to help you
safeguard your community. •
In Summary-
Even though the transportation of
hazardous materials presents substantial
risks, these risks may seem difficult to
quantify. The commodity flow study
process should be tailored to meet your
needs and available resources as you
identify and address the particular
hazards facing your community.
In this document, we have:
0 Outlined the steps necessary to
conduct a comprehensive
commodity flow study:
0 Explained how each of these steps
relate to the emergency planning
process:
0 Pointed out some resources you may
want to tap once you have decided
to go ahead with a CFS; and
0 Examined the technologies and
issues that will play a role in
identifying transportation hazards in
the future.
Use this information as a guideline, but
remember that there is no one right way
of doing this job. The particulars of your
community will ultimately determine
your best course of action. •
