Hazardous materials are chemical substances, which if released or misused can pose a threat
to the environment or health. Hazardous materials come in the form of explosives, flammable
and combustible substances, poisons, and radioactive materials and can cause death, serious
injury, long-lasting health effects, and damage to buildings, homes, and other property.

Varying quantities of hazardous materials are manufactured, used, or stored at an estimated 4.5
million facilities in the U.S.--from major industrial plants to local dry cleaning establishments and
gardening supply stores. As many as 500,000 products pose physical or health hazards and
can be defined as "hazardous chemicals” (FEMA, 2013).

Hazardous materials incidents can occur anywhere. Communities located near chemical
manufacturing plants are particularly at risk. However, hazardous materials are transported on
our highways, railroads, waterways, and pipelines daily, so any area is considered vulnerable.
In 2012, there were 13,844 transportation-related hazardous materials incidents nationwide that
resulted in 10 deaths and 160 injuries. The Montana Department of Transportation regulates
transportation routes and speed limits used by carriers and monitors the types of hazardous
materials crossing state lines.

The volume and type of hazardous materials that flow into, are stored, and flow through
communities determine exposure to a potential release of hazardous materials.
The
Emergency Planning and Community Right-to-Know Act (EPCRA) was enacted in 1986 to
inform communities and citizens of chemical hazards in their areas. EPCRA requires
businesses to report the locations and quantities of chemicals stored on-site to State and local
governments in order to help communities prepare to respond to chemical spills and similar
emergencies. EPCRA also requires EPA and the States to annually collect data on releases
and transfers of certain toxic chemicals from industrial facilities, and make the data available to
the public in the Toxics Release Inventory (TRI). In 1990 Congress passed the Pollution
Prevention Act which required that additional data on waste management and source reduction
activities be reported under TRI. The goal of TRI is to empower citizens, through information, to
hold companies and local governments accountable in terms of how toxic chemicals are
managed. Table 4.4.7-1 presents TRI data for Montana facilities.

Table 4.4.7-2 shows a summary of the hazardous material incidents in Montana from 2000 to
2012 reported to the National Response Center (NRC) by type of release. During this time,
1,985 incidents were reported. Of these, 47 percent were from fixed facilities compared to the
national average of 36 percent. Mobile facilities, including aircraft and railroad incidents,
accounted for 32 percent of the incidents, compared to the 14 percent national average.

Alberton Chlorine Spill: On April 11, 1996, 19 cars from a Montana Rail Link freight train
derailed near Alberton, Montana. Six of the derailed cars contained hazardous materials. One
derailed tank car containing chlorine (a poison
gas) ruptured, releasing 130,000 pounds of
chlorine into the atmosphere; another tank car
containing
potassium
hydroxide
solution
(potassium cresylate, a corrosive liquid) lost
17,000 gallons of product; and a covered hopper
car containing sodium chlorate (an oxidizer)
spilled 85 dry gallons onto the ground. This
chlorine spill is the second largest in U.S.
history.
16
17
18
19
20
21
About 1,000 people from the surrounding area
were evacuated. Approximately 350 people
were treated for chlorine inhalation, 123 of whom sustained injury. Nine people, including both
members of the train crew, were hospitalized. A transient riding the train died from acute
chlorine toxicity.

26
U.S. Interstate Highway 90 (I-90) is roughly parallel and about 150 yards north of the MRL
tracks at the accident site. The hazardous material cloud drifted across I-90 resulting in multiple
highway traffic accidents. Several motorists were stranded in the cloud after these accidents. I90 was closed requiring an 81-mile detour. Monetary damage was estimated to be $10 million.
27
28

31
The Governor of Montana declared a state of emergency in Missoula and Mineral Counties. On
April 14, 1996 the evacuation area was reduced to 15 square miles; residents were temporarily
escorted into the area to feed and water livestock animals, retrieve some personal possessions,
and locate pets (NTSB, 1998).

Flathead Lake Petroleum Tanker Spill: A major toxic spill into Flathead Lake occurred in April
2008 when a tanker truck crashed on Highway 35 and spilled 6,400 gallons of gasoline on the
East Shore south of Finley Point. The crash forced five families who lived nearby from their
lakeshore homes. The EPA ordered the trucking company to clean up the contamination
associated with the spill in order to fully protect the health of local residents and the renowned
aquatic and recreational resources provided by Flathead Lake. The cleanup involved removing
contaminated soils and water and elimination of hazardous vapors in nearby residences. The
2008 tanker truck spill caused over $1 million in damages.

Yellowstone River Oil Pipeline Spill: On July 1, 2011, a break occurred in the ExxonMobil
Silvertip 12-inch crude-oil pipeline that crosses under the Yellowstone River approximately 20
miles upstream from Billings, Montana. ExxonMobil reported an estimated 63,000 gallons of oil
entered the river before the pipeline was shut down.
14

The Environmental Protection Agency (EPA) and U.S. Fish and Wildlife Service conducted an
aerial survey that identified oil deposited along the river banks, and pools of oil in backwaters
and eddies along the north and south banks of the river. At the time of the survey, oil was visible
along the river for 45 miles downstream from the location where the pipeline broke, near Laurel,
Montana.

EPA ensured that the ExxonMobil Pipeline Company addressed all potential impacts of the spill
and provided direction and oversight that cleanup and restoration of the Yellowstone River and
people's health and the environment were protected. There were over 1,000 personnel engaged
in cleanup and shoreline assessment efforts. Shoreline Cleanup Assessment Technique
(SCAT) teams assessed more than 6,500 acres.
EPA sampling results for air, water, soil, and sediment showed there were no levels of concern
in the water and no elevated levels above instrument detection for volatile organic compounds.

Two separate incidents that occurred within one week of each other are the only two state
emergency declarations for hazardous material release: the Alberton Chlorine Spill (EO-8-96)
and another derailment involving a chlorine tanker car near Dodson (EO-9-96). The Dodson
derailment did not cause a chlorine release. There have been no federal disaster declarations
associated with hazardous material incidents in Montana.

17
Hazardous materials incidents can cause death, serious injury, long-lasting health effects, and
damage to buildings, homes, and other property. The magnitude of the hazard is often
expressed as a percentage of property damage caused by the incident. Table 4.4.7-3 presents
property damage associated with the top transportation-related hazardous material incidents in
Montana over a 23 year period. This data indicates that $15.66 million in damages have
resulted from hazardous material incidents during this period; $4 million from highway accidents
and $11.6 million from railroad accidents.
18
19
20
21
Probability is based on the frequency of the hazard over a 10 year period. Since hazardous
material incidents occur more than once per year, the probability rating is “highly likely” for this
hazard.

To model hazardous material incident risk a GIS data layer of transportation arteries was
developed which included highways, major roadways, and railroads. Facilities with hazardous
materials or petroleum reporting requirements from EPA’s Toxic Release Inventory were added
to this layer and it was then buffered by 0.25 miles. Figure 4.4.7-1 depicts the hazardous
material incident layer used in the PDM analysis. Pipeline data was incomplete and therefore,
not included in the hazard layer.

Building exposure was calculated by intersecting the hazardous material buffer with the MDOR
cadastral parcel and state critical facility datasets. Estimates of vulnerable population were
calculated using census block data within the hazard area. Exposure values are presented in
Table 4.4.7-4. The Hazardous Material Incidents section in Appendix B presents supporting
documentation from the risk assessment including a list of critical facilities in the hazardous
material incident buffer and exposure estimates by county.

Table 4.4.7-5 presents a vulnerability summary of the hazardous material incident hazard as it
relates to percent exposure and growth rates in Montana’s counties, cities and towns. Percent
exposure was derived by dividing the value of residential and commercial/agricultural/industrial
building stock exposed to the hazard into the total value of the building stock. Percent exposure
is a more accurate way of displaying vulnerability than presenting jurisdictions with the highest
exposure because it reflects areas with the greatest risk opposed to those with high value real
estate. A complete ranking is presented in the Hazardous Material Incident section of
Appendix B.
15
19
Counties with the highest hazardous material incident exposure include: Mineral, Deer
Lodge, Sheridan, Big Horn, and Custer; while the top cities/towns include: Poplar and
Culbertson (Roosevelt Co.), Whitehall (Jefferson Co.), Harlem (Blaine Co.), and
Browning (Glacier Co.). Figure 4.4.7-2 presents percent exposure for the top counties and
20
cities/towns showing regional vulnerability.

Percent exposure was multiplied by the population change between the 2000 and 2010 census
to present the jurisdictions with the highest risk that are experiencing the fastest growth. A
complete ranking is presented in the Hazardous Material Incident section of Appendix B.

Counties with the highest hazardous material incident exposure experiencing the fastest
population growth include: Broadwater, Gallatin, Missoula, Flathead, and Yellowstone;
while the top cities/towns (with population over 500) are Belgrade (Gallatin Co.),
Fairview (Richland Co.), Columbia Falls and Kalispell (Flathead Co.), and East Helena
(Lewis and Clark Co.). Figure 4.4.7-3 presents percent exposure and population change for
the top counties and cities/towns showing the most vulnerable areas experiencing the fastest
population growth.

Current data and history do not suggest that State property is highly vulnerable to hazardous
material releases; however, depending on the proximity of State facilities to hazardous material
transportation routes and fixed facilities, some locations may be more vulnerable than others.
Critical facilities and bridges located in the hazard area are listed in the Hazardous Material
Incident section of Appendix B.

The Hazardous Material Incident section in Appendix B presents an exposure summary for
hazardous material incidents as reported in the Local PDM Plans. Losses from hazardous
material incidents are described in terms of their effect on buildings, society, and the economy,
as outlined below:

34

Building exposure is presented either as a dollar value or high-moderate-low rating and
typically refers to the vulnerability of residential structures and/or critical facilities from
the hazard.
Societal exposure is presented either as the number of lives at risk or as a highmoderate-low rating representing the vulnerability of human life from the hazard.
Economic exposure is presented as a dollar value or high-moderate-low rating referring
to the potential impact to the economy from the hazard.

Approximately 75 percent of the local PDM plans evaluated the hazardous material incident
hazard in their risk assessment. Of those with quantified results, Cascade County had the
highest exposure followed by Silver Bow, Lewis and Clark, and Lake Counties. Plans reporting

Much of the future development currently occurring in the State is off of the major road and rail
networks. The potential does exist for development of agricultural lands bordering the highways
and railroad, particularly in the unincorporated parts of the State. Very few restrictions are in
place to prevent development in these areas.

Risk assessment methodology involved using GIS to intersect the hazard layer with parcel data
from the Montana Dept. of Revenue and census block data from the 2010 U.S. Census. If the
GIS intersect clipped any part of a parcel then the entire value and number of structures in that
parcel were assumed to be located in the hazard area. This may lead to an over reporting of
exposure where parcels are large. In determining population exposure, if the GIS intersect
clipped a census block then the entire number of individuals in that census block were assumed
to reside in the hazard area which may lead to over reporting of population at risk where census
blocks are large.

Risk assessment results are only a general representation of potential vulnerabilities. The risk
assessment methodology used GIS intersecting parcel data with the hazard layer. If the
intersect included any portion of a parcel, structures on the parcel were assumed to be within
the hazard area. This may have led to a slight over reporting of building exposure.
