ABSTRACT

The City of Corpus Christi/Nueces County Local Emergency Planning Committee, in partnership with the Corpus Christi Metropolitan Planning Organization and with technical assistance from Texas A&M Transportation Institute, conducted a hazardous materials truck transportation commodity flow study using data collected between April 2016 and September 2016. The report summarizes data by hazmat placard ID, material class, division, special hazards, and transport vehicle types.

EXECUTIVE SUMMARY

The City of Corpus Christi/Nueces County Local Emergency Planning Committee (LEPC), in partnership with the Corpus Christi Metropolitan Planning Organization (MPO) and with technical assistance from Texas A&M Transportation Institute (TTI) conducted a hazardous materials (hazmat) commodity flow study (CFS) in 2016 to update a previous CFS for the area from 2010. The impetus for this work arose when decision makers in the region raised the question as to whether undertaking a routing process for hazardous materials truck traffic would minimize risk on the new Harbor Bridge. Upon investigation, local transportation and emergency planners determined that updated commodity flow data were needed to make such a determination.

The 2016 study had two primary components: 1) Collect and evaluate truck hazmat transportation observational data in the Corpus Christi Ship Channel area; and 2) Collect and evaluate truck hazmat transportation shipment data from major facilities in the Ship Channel area. The first of these was successfully completed and provides new information about hazmat traffic levels and corresponding materials that are transported in the Corpus Christi area. The second could not be completed, and is discussed further below.

HAZMAT TRUCK TRAFFIC

Hazmat truck traffic in the Corpus Christi Ship Channel area corresponds with the significant presence of major petroleum refining and distribution terminal facilities. Of the major roadways into and out of the Corpus Christi area, hazmat truck traffic on I-37—more than 580 trucks per weekday, daytime period—was more than three times higher than was observed on US 181—approximately 190 trucks per weekday, daytime period. Based on limited observations, hazmat truck traffic on SH 358 south of I-37 totals more than 200 trucks per weekday, daytime period.

Compared with traffic reported on for the 2010 study, it appears that hazmat truck traffic on I-37 has increased by approximately 50 to 75 percent in 2016 as compared with 2010. On US 181, there may have been a slight decrease in frequency of hazmat truck traffic in 2016 compared with 2010. These findings should be considered in light of the differences in data collection personnel for the 2010 and 2016 studies, which limits the ability to make direct comparisons in traffic levels for the two studies.

The Joe Fulton Corridor had the lowest hazmat truck traffic levels of any major industry arterial roadway that was observed in the 2016 study. While total truck traffic on the Joe Fulton Corridor was in the hundreds of trucks per daytime period (6 a.m. to 6 p.m.) on weekdays, the total hazmat traffic on the corridor during the same period was between 20 and 40 trucks. This is likely due to the limited number of hazmat facilities along the north side of the Corpus Christi Ship Channel.

Much higher levels of hazmat truck traffic were observed on roadways that are arterials for major industrial facilities along the south side of the Ship Channel area, over 200 trucks per weekday, daytime period on some roadways. The highest average levels of hazmat truck traffic


in this area were observed on Suntide Road, north and south of Up River Road, on Buddy Lawrence Drive, on Up River Road west of Valero Way, and on Valero Way.

Local and regional truck traffic patterns for facilities located along major industry arterial roads can vary greatly from one location to another. It is not necessarily reasonable to assume that because a facility is on the west side of the Ship Channel area, most of its corresponding traffic is on I-37, or that because a facility is on the east side of the Ship Channel area, most of its corresponding traffic is on US 181.

HAZARDOUS MATERIALS TRANSPORTED BY TRUCK

Seven placard IDs represent nearly 75% of all daytime (6 a.m. to 6 p.m.) hazmat placard observations during weekdays in 2016, and over 90% of all daytime placard observations on weekends. Most of these materials are associated with major petroleum refining and petroleum product distribution terminal operations. In order of their weekday prevalence, these placard IDs and their corresponding material classes and informal names are:

1203, Class 3, Gasoline 1993, Class 3, Flammable liquids, including but not limited to diesel fuel 1267, Class 3, Petroleum crude oil 1075, Class 2.1, Liquefied petroleum gas 2448, Class 4.1 or Class 9, Molten sulfur 3257, Class 9, Elevated temperature liquid, including but not limited to hot mix asphalt 1268, Class 3, Petroleum distillates or petroleum products

There were very few ‘special’ hazard placards observed in the 2016 study. This designation refers to materials that can require unique or specialized response procedures, training, equipment, or protective action considerations, and they are often materials that are much less frequently observed in transport than the materials listed above. Special hazards include explosive, toxic inhalation hazard, violent polymerization, gas-producing water reactive, and radioactive materials. Out of over 2,600 trucks with hazmat placards that were observed for the study, only 10 were placarded for these special hazards materials.

FACILITY SURVEY

As part of the 2016 study, a survey form was developed and provided to industrial facilities through a secondary party to request origin and destination information about truck shipments. Those facilities that were unwilling to complete the survey were asked to provide data they may have previously submitted to US DOT for a sample of shipments in 2012. None of the facilities provided the requested data for this study. Because of this, no data were obtained about hazmat shipment origins and destinations that would inform about distances over which materials are transported, which is an important component of risk calculations.

TRUCK HAZMAT TRANSPORTATION AND THE HARBOR BRIDGE

As discussed previously, most of the hazmat truck traffic into and out of Corpus Christi is on I-37, followed by SH 358/SH 44, and then US 181. In addition, the total estimated hazmat truck


traffic on the major highways into and out of Corpus Christi corresponds closely with total estimated hazmat truck traffic on major industry arterial roadways along the south side of the Corpus Christi Ship Channel. This suggests that the majority of hazmat truck traffic in the area has origins or destinations in Corpus Christi, and only a minority of traffic is likely travelling through Corpus Christi. However, further data on origins and destinations of hazmat truck shipments in the Corpus Christi area are needed to confirm this initial assessment.

Completion of the new Harbor Bridge is scheduled for 2021. If hazmat truck traffic patterns remain consistent in 2021 with 2016, we expect that the majority of hazmat truck traffic in the Corpus Christi area would not be affected by a hazmat routing process involving the new Harbor Bridge. This is because most of this traffic is to the west (north via I-37) of the new Harbor Bridge and appears to originate or terminate in the south Corpus Christi Ship Channel area, and thus does not use the Harbor Bridge.

A hypothetical hazmat route designation1 that limited traffic on the new Harbor Bridge would affect traffic over US 181, which was estimated to be approximately 190 trucks during weekday, daytime period in 2016. Diverting these trucks over the Joe Fulton Corridor would likely increase the hazmat truck traffic levels on the corridor from the current levels of between 20 to 40 trucks per weekday, daytime period to over 200 hazmat trucks per weekday, daytime period. It would also increase the distances traveled by trucks that have origins or destinations at facilities in the south Ship Channel area. It is possible that the number of hazmat truck accidents in the area might actually increase due to increased distances travelled, but the consequences of a given accident might decrease because some of them would occur on lower-speed roads at grade (e.g., on Joe Fulton), as opposed to higher-speed roads above grade (e.g., US 181 and I-37) and at greater distances from some residential areas (but possibly closer to others).

The risk tradeoffs between route alternatives can be quantitatively estimated, and are a necessary component of hazmat route determinations. This study provides information about hazmat truck traffic levels and material characteristics in the Corpus Christi Ship Channel area that can be used in risk calculations. Route characteristics, accident rates, release mechanisms, population proximity, and response capability information can all be determined from analysis of existing data or other secondary sources (such as previous studies). However, due to the lack of information about hazmat shipment origins and destinations for hazmat trucks in the Corpus Christi area, we are not yet able to quantify the increase in travel distances or the increase in hazmat traffic that is likely on other corridors in the industrial areas if a hazmat routing process were to restrict hazmat traffic on the Harbor Bridge.

RECOMMENDATIONS

We recommend that the LEPC, emergency planners and responders, and other interested parties:

Review the findings of this study, Evaluate the status of current and future response and community preparedness, and

1 Any NRHM hazmat routing process that might be undertaken for Corpus Christi in the immediate future would be voluntary, in that jurisdictions with populations of more than 850,000 are required under Texas Transportation Code to develop NRHM routes. The population of Corpus Christi was approximately 320,000 in 2014.


Identify and address associated needs and gaps.

Specific and actionable recommendations are provided in the Guide for Using Hazmat

Transportation Information that accompanies this report.

With respect to definitively determining whether a routing process for hazmat is justified to reduce risk exposure on the new Harbor Bridge, our recommendation is twofold:

1. Additional data on hazmat truck traffic origins and destinations in the Corpus Christi area should be obtained and evaluated. Ideally, these data should be acquired directly from industrial facilities in the region. Pending the success of this effort, additional traffic observations might be collected using methods and technologies such as interviewing truck drivers about shipment origins and destinations, using video or still image technologies, or other methods of ascertaining truck traffic patterns to augment the observational data set collected as part of the 2016 CFS.

2. Once the supplemental data collection specified in recommendation #1 above is complete, decision makers in the Corpus Christi area should conduct a risk tradeoffs analysis in the future to determine whether a routing process for hazmat is justified based on the anticipated reduction in risk exposure.

1. OVERVIEW

The City of Corpus Christi/Nueces County LEPC and TTI, in partnership with the Corpus Christi MPO, conducted a hazardous materials (hazmat) commodity flow study (CFS) in 2016 to update information from a previous CFS for the area from 2010. Since 2010, construction of the Joe Fulton Corridor has been completed, providing a new connector route between I-37 at the west end of the Corpus Christi Ship Channel and the US 181 Causeway above the current Harbor Bridge. The former Tule Lake Lift Bridge off Navigation Boulevard has been removed. Construction has also been initiated on a new Harbor Bridge, with scheduled completion in 2021.

Responsibility for ensuring the safe and secure transport of hazardous materials and minimizing corresponding public and environmental exposure and risk in the Corpus Christi area is shared by transportation carriers such as commercial motor vehicle companies and operators, facilities, the Corpus Christi Fire Department and other response agencies, emergency and transportation planners, and elected officials. Risk can be thought of in terms of probability of exposure times the consequences of that exposure. Risks for hazmat transportation are thus influenced by traffic levels, accident rates, distances over which materials are transported, the types of materials and their corresponding characteristics, and population proximity.

The impetus for this work arose when decision makers in the region raised the question as to whether a routing process for Non-Radioactive Hazardous Material (NRHM) was justified to minimize risk on the impending new Harbor Bridge. Upon investigation, local transportation and emergency planners determined that updated commodity flow data were needed to make such a determination. The goals of the 2016 study were to evaluate changes in chemical transportation patterns and hazards since 2010, provide new information about hazmat transport patterns in the area, including hazmat shipment origins and destinations, and update the baseline of information that can be used for potential future risk assessments.

The study had two primary components: 1) Collect and evaluate truck hazmat transportation observational data in the Corpus Christi Ship Channel area; and 2) Collect and evaluate truck hazmat transportation shipment data from major facilities in the Ship Channel area. The first of these was successfully completed and provides new information about hazmat traffic levels and corresponding materials. Observational data collection was conducted in the public right of way and from facility properties along roadways, with the cooperation of facility safety and security personnel. Figure 1 shows a map of data collection locations for the 2016. Table 1 lists data collection activity by roadway segment for weekdays and weekends, including hours of data collection, observations of all commercial trucks, and observations of placarded trucks.

The second part of this project could not be completed. A survey was developed and provided to Ship Channel area facilities, along with requests for alternate sources of shipment data. However, facility representatives were unwilling or unable to provide the requested data. Because of this, no data were obtained about hazmat shipment origins and destinations, which would inform about distances over which materials are transported, another important component of risk calculation. Future efforts to obtain shipment origin and destination information may benefit from further discussions with facility representatives to communicate the need for and use of the information, or alternate data collection approaches.

2. TRUCK TRAFFIC

2.1. TRUCK TRAFFIC LEVELS

Table 2 lists estimated weekday, daytime (6 a.m. to 6 p.m.) number of placarded trucks on observed roadway segments. The estimates are for both directions of traffic, combined. For example, an estimate of 187 hazmat trucks per daytime period on US 181 includes both US 181 northbound and southbound directions. Information from Table 2 for major highway and industry arterial roadways is depicted in the maps shown in Figures 2, 3, and 4.

Table 3 lists estimated weekday, daytime number of all commercial trucks on observed roadway segments, and Table 3 lists the average percentages of all commercial trucks that were observed with hazmat placards during the weekday, daytime periods. Further information about hazmat and overall truck traffic patterns for each observed roadway segment can be found in Appendix C.

Peak hazmat observations in 2016 on I-37 were during the 9 a.m. hour, with more than 60 hazmat trucks (both directions combined). Throughout the daytime period (6 a.m. to 6 p.m.), hazmat truck traffic typically ranged between 40 and 60 trucks per hour, with an estimated total of more than 580 trucks per weekday, daytime period on I-37 at Hart Road.

Compared with traffic reported on for the 2010 study, it appears that hazmat truck traffic on I-37 was about 50 to 75 percent higher in 2016 compared with 2010. The average frequency of observed hazmat trucks was 48 trucks per hour (both directions combined) during weekdays on I-37 at Hart Road in 2016, compared with 32 trucks per hour in 2010.2 Between 15 and 17% of observed commercial trucks on I-37 were placarded during weekdays in 2016, and over 40% were placarded on weekends.

Hazmat truck traffic observations peaked in the morning on US 181 between 9 a.m. and 11 a.m., and in the afternoon from 4 p.m. to 5 p.m. There may have been a slight decrease in frequency of hazmat truck traffic on US 181 in 2016 compared with 2010. The average frequency of observed hazmat trucks was 16 trucks per hour (both directions combined) on US 181 in 2016, compared with 22 trucks per hour in 2010. Total estimated weekday, daytime hazmat truck traffic on US 181 was nearly 190 trucks. A weekend hourly frequency of hazmat truck traffic was 12 trucks per hour (both directions combined) in 2016, compared with 18 trucks per hour in 2010.3 Around 10% of commercial trucks on US 181 that were observed during weekdays in 2016 were placarded, and 15% were placarded on weekends.

2 Because the data collection personnel (and their corresponding experience with data collection) were different in 2010 and 2016, it is possible that there actually may be little or no increase of hazmat truck traffic on I-37 in 2016 compared with 2010. LEPC volunteers and TTI personnel collected traffic data in 2010, and most of the data collection at this location in 2010 was collected by the LEPC. All traffic data for the 2016 study were collected by TTI. Using data collected only by TTI personnel in 2010 and 2016, we found little difference in hazmat truck traffic averages for I-37. This finding should be considered in light of the fact that TTI’s observations comprised only a minority of the 2010 data and thus may not have provided a good representation of traffic levels in that year. 3 Similar to I-37 data, these differences should take into consideration that data collection personnel were not the same in 2010 and 2016. LEPC volunteers conducted nearly all of the traffic observations on US 181 in 2010, and TTI personnel conducted all of traffic observations in 2016.

Based on the collected data, there was an average of around 18 hazmat trucks per hour (both directions combined) on SH 358 between SH 44 and I-37 during the daytime on weekdays. SH 358 had limited truck traffic observations, and the based on that data there were an estimated 18 hazmat trucks per hour (both directions combined) on SH 358. There were minimal hazmat truck traffic observations during limited data collection on SH 286. Further data are needed to evaluate the level and consistency of hazmat truck traffic on SH 286 and SH 358.

The Joe Fulton Corridor had the lowest hazmat truck traffic levels of any major industry arterial roadway that was observed in the 2016 study. While total traffic on the Joe Fulton Corridor was in the hundreds of commercial trucks per daytime (6 a.m. to 6 p.m.) on weekdays, the total hazmat traffic on the corridor for during the same period was between 20 and 40 trucks. This is likely due to the limited number of hazmat facilities along the north side of the Corpus Christi Ship Channel. On the west side of the Corridor at I-37, there were around two hazmat trucks per hour on average (4% of total truck traffic) during the daytime on weekdays (both directions combined). On the east side of the Corridor at US 181, there were around three hazmat trucks per hour, on average (8% of total truck traffic).

The City of Corpus Christi Traffic Engineering Department collected truck classification and count data using a radar system on westbound Joe Fulton Corridor, immediately south of Burleson St., from 11 a.m. on July 18, 2016 through 9 a.m. on July 20, 2016. Based on averages from these data, over a 24-hour period 78% of all vehicle counts at this location that were classified as 40-feet or longer in length (assumed to be heavy trucks) were attributable to daytime hours between 6 a.m. and 6 p.m.

Much higher levels of hazmat truck traffic were observed on roadways that are arterials for industrial facilities along the south side of the Ship Channel area, over 200 trucks per weekday, daytime period on some roadways. Most of the roadways in this area are two-lane roads, with narrow or no paved shoulders, traffic lights at some major intersections, and a few paved turning lanes or pull-off areas near some facility entrances. Between 20% and 50% of truck traffic in the south Ship Channel area was observed with hazmat placards, depending on location. The highest average levels of hazmat truck traffic in this area were observed on Suntide Road, north and south of Up River Road, on Buddy Lawrence Drive, on Up River Road west of Valero Way, and on Valero Way. These roads had between 15 and 20 placarded trucks per hour (both directions combined) during the daytime on weekdays. Hazmat truck traffic levels on most other observed south Ship Channel area road segments in the area were around half of that, or less.

The City of Corpus Christi Traffic Engineering Department also collected truck classification and count data using a radar system on Up River Road, east of Rand Morgan Drive, from 12 p.m. on June 7, 2016 through 11 a.m. on June 10, 2016. Based on averages from these data, over a 24-hour period 77% of all vehicle counts at this location that were classified as 40-feet or longer in length were attributable to daytime hours between 6 a.m. and 6 p.m.

The south Ship Channel area, roadway arterials connect with I-37 main lanes using frontage roads. Along the I-37 northbound frontage road, daytime hazmat truck traffic was highest north of Buddy Lawrence Drive (around nine hazmat trucks per hour), and north of Up River Road and south of Valero Way (around five hazmat trucks per hour on each).


2.2. HAZMAT TRUCK TRAFFIC PATTERNS

Observational data collected at three road locations provides some information about the general directions and truck origins and destinations for three industry arterial roadways in the Ship Channel area.

Figure 5 shows an example for Buddy Lawrence Drive, north of I-37. At this location, there were an estimated 202 hazmat placarded trucks in both directions on weekdays during the daytime. Based on a sample of nine 30-minute periods of traffic observations, about 65% of that truck traffic came from or went toward I-37 on the north (west) side of the intersection of Buddy Lawrence Drive and I-37, and 30% came from or went toward I-37 on the south (east) side of that intersection. For Nueces Bay Boulevard, north of I-37 (Figure 6), 100% of the hazmat truck traffic came from or went toward I-37 on the north (west) side of that intersection, based on a sample of four 30-minute periods of traffic observations.

At Valero Way, the traffic patterns are reversed (Figure 7). On the Valero Way segment north of I-37, there were an estimated 178 hazmat placarded trucks in both directions on weekdays during the daytime. Based on a sample of eight 30-minute periods of traffic observations, approximately 55% of that truck traffic came from or went toward I-37 on the south (east) side of the intersection of Valero Way and I-37, 22% came from or went toward I-37 on the north (west) side of the intersection, and 22% came from or went toward Valero Way on the south side of the intersection.

It is important to note that these split estimates are based on limited number of 30-minute count periods at each location, and the estimates should be regarded as preliminary. However, they do suggest that truck traffic patterns for different major industry arterial roads can vary greatly from one arterial roadway to another. It is not accurate to assume that because a facility is on the west side of the ship channel area, most of its corresponding traffic is on I-37, or, conversely, that because a facility is on the east side of the ship channel area, most of its corresponding traffic is on US 181. This also highlights the need for specific data about regional truck traffic patterns for major industry arterials in the area.

3. HAZARDOUS MATERIALS

3.1. OBSERVED HAZARDOUS MATERIALS PLACARDS

Eight specific placard IDs, listed below, represent over 75% of all daytime (6 a.m. to 6 p.m.) placard observations during weekdays in 2016 for the data collection locations shown in Figure 1, and seven of these (not including ID 1011) account for over 90% of all daytime placard observations on weekends.4 In order of their weekday prevalence, these placard IDs and their corresponding material classes and informal names are:

1203, Class 3, Gasoline 1993, Class 3, Flammable liquids, including but not limited to diesel fuel 1267, Class 3, Petroleum crude oil 1075, Class 2.1, Liquefied petroleum gas 2448, Class 4.1 or Class 9, Molten sulfur 3257, Class 9, Elevated temperature liquid, including but not limited to hot mix asphalt 1011, Class 2.1, Butane 1268, Class 3, Petroleum distillates or petroleum products Table 4 lists observed weekday, daytime placard IDs for all data collection locations in

Corpus Christi and the percentages of all placards they represent. The percentages are based on placard counts on major roadway segments corresponding to these locations, weighted by estimated hazmat truck traffic levels over the daytime period on corresponding roadway segments to normalize observations to a consistent time period. The table identifies material classes and names for all placard IDs that represented 1% or more of all weighted placard observations for the study.

There were very few ‘special’ hazard placards observed in the 2016 study. The term ‘special’ refers to materials that can require unique or specialized response procedures, training, equipment, or protective action considerations, and they are often materials that are much less frequently observed in transport than more common materials such as flammable liquids. Special hazards include explosive, toxic inhalation hazard, violent polymerization, gas-producing water reactive, and radioactive materials.

Calling them ‘special’ does not necessarily mean they are more ‘dangerous’ than other types of hazardous materials. For example, a transportation incident involving a loaded tanker of gasoline or liquefied petroleum gas (LPG) can have significant population or environmental impacts. So can a leaking cylinder of chlorine, which is a toxic inhalation hazard. However, most emergency responders deal much more frequently with materials such as gasoline and diesel fuel (e.g., leaking fuel tanks in traffic accidents) or LPG than they do chorine, and so the experience, training, and equipment in most departments reflects this.

4 Because many of the hazmat placard observations for the 2010 study provided some but not all of the information about placard IDs (for example, identifying that a placard was ‘Red’ or ‘White’ but not a placard ID number), it was not possible to conduct a statistical comparison of whether the types of placards or their corresponding classes were significantly different in 2016 and 2010.


Out of over 2,600 hazmat placarded truck observations in the 2016 study: Three trucks were placarded for explosive materials (not more-specifically identified); Five trucks were placarded for toxic inhalation hazard materials, including anhydrous

ammonia (1), chlorine (3), and nitric oxide (1); One truck was placarded for a violent polymerization material, stabilized ethyl acrylate; One truck was placarded for a gas-forming water-reactive material,

dodecyltrichlorosilane; and No trucks were observed with radioactive materials placards. However, there were 68

observations of non-destructive testing (NDT) trucks, some of which may contain shielded radioactive materials. These trucks typically do not require radioactive materials placards under federal hazardous materials transportation regulations. Further information about NDT trucks can be found at the end of Appendix B.

3.2 HAZARDOUS MATERIALS CLASSIFICATIONS

Class 3 (Flammable and combustible liquids) materials represented nearly 60% of all daytime placard observations for the locations shown in Figure 6 on both weekdays and weekends in 2016. Adding Class 2.1 (Flammable gases), and Class 9 or 4.1 (Mostly molten sulfur, or liquid or solid hazardous waste or environmentally hazardous substances) materials, approximately 90% of daytime placard observations are represented during weekdays and weekends. Figure 8 shows the percentages of weekday placard observations represented by different material classes.

The top hazmat placard classes were generally consistent across data collection locations. Class 3 flammable and combustible liquids were the most frequently observed class of hazmat placard at every location. For the next top classes, their order of frequency varied somewhat.

Further information about the most frequent placard IDs and their classes can be found in Appendix C for roadway segments from each data collection location.

3.3 EMERGENCY RESPONSE GUIDE NUMBERS

Table 6 lists Emergency Response Guide (ERG) numbers for hazmat placards listed in Table 5. The ERG is a guidebook for first responders to use in making initial assessments of material hazards and corresponding protective actions, based on type and magnitude of the incident. The current version of the ERG was released in 2016. The ERG classifications in Table 6 are based on cross linkages between placard IDs and ERG numbers from the 2004 ERG, which is the most recent year available for the crosslink dataset.

4. FACILITY SURVEY

As part of the 2016 study, a survey form was developed to request origin and destination information about shipments to and from truck loading racks and terminal locations at facilities. Based on communications received through a secondary party that was coordinating the facility information request, it is our understanding is that facilities expressed uncertainty about the purpose and use of the requested information and the availability and amount of work necessary to compile and provide such information. None of the facilities provided the requested survey data for this study.

Some shippers already provide information to the US DOT Bureau of Transportation Statistics (BTS) about shipment commodity types and volumes, and origins and destinations. The BTS survey is conducted every five years, and the most recent survey was conducted in 2012. This information could be used a basis for estimating shipment origins and destinations, and corresponding distances travelled. However, the information from specific facility responses is not available outside of BTS, and available BTS data are not sufficient to estimate shipment origins and destinations at a micro scale since they are aggregated at metropolitan area levels. Despite the limitations of these data, we suggested that facilities which were unwilling to complete the survey that was developed for LEPC’s 2016 study might provide a copy of thei2012 BTS survey as an alternative; none of the facilities provided 2012 BTS survey data for this study.


5. SUMMARY AND RECOMMENDATIONS

5.1 LOCAL AND THROUGH HAZMAT TRUCK TRAFFIC

Hazmat truck traffic and observed placards on trucks in the Corpus Christi Ship Channel area corresponds with the significant presence of major petroleum refining industries and distribution terminal facilities. Based on the proportions of all placards represented by these materials, along with levels of hazmat truck traffic on major industry arterial roadways in the Ship Channel area described in Section 2, it appears that the large majority of hazmat truck traffic in the Corpus Christi Ship Channel area either originates or terminates there. However, further data on origins and destinations of hazmat truck shipments in the Corpus Christi area are needed to confirm this initial assessment.

Figures 2, 3, and 4 illustrate weekday, daytime hazmat truck traffic estimates in the area. The combined weekday, daytime hazmat truck traffic on I-37 at Hart Road, the US 181 Causeway north of the Harbor Bridge, and SH 358 south of I-37 is approximately 990 trucks. The combined hazmat truck traffic on the major industry arterial roadways in the ship channel area (Joe Fulton Corridor, Up River Road at Rand Morgan, Suntide Road, Valero Way, Navigation Boulevard, Up River Road at I-37, Buddy Lawrence Drive, and Nueces Bay Boulevard) totals around 900 trucks for the same period. Note this is very close to the total for the major highways into and out of Corpus Christi, suggesting that most of this traffic originates or terminates in the Ship Channel area. Further, most but not all of major industry arterial roadways in the Ship Channel area were included in the study, so the total corresponding Ship Channel area hazmat truck traffic is likely greater than 900 trucks.

This does not mean that there is an absence of ‘through’ hazmat truck traffic on US 181 and either I-37 or SH 358/SH 44, only that it likely represents a minority of truck traffic. Validating this conclusion and quantifying the amount of through hazmat truck traffic, along with better information about the origins and destinations of shipments in the Corpus Christi area, would be important for calculating distances traveled by trucks and corresponding population and environmental risk exposure potentials.

5.2. USING INFORMATION FOR QUANTITATIVE RISK ASSESSMENT

With planned completion of the new Harbor Bridge in 2021, local decision makers have raised the question as to whether undertaking a routing process for hazardous materials truck traffic would minimize risk on the new Harbor Bridge. Based on data collected to date, we expect that the majority of hazmat truck traffic in the Corpus Christi area would not be affected by such a restriction. By far the largest share of hazmat truck traffic on the major roadways into and out of the Corpus Christi area is on I-37 (around 580 trucks per weekday, daytime period), and the traffic observations provide a reasonable initial expectation that most of this traffic is originating and terminating in the south Corpus Christi Ship Channel area. Although hazmat truck traffic levels were lower on SH 358 south of I-37 (albeit with limited observations to confirm this), we have the same expectation for hazmat truck traffic on SH 358.


A hazmat routing process that limited traffic on the new Harbor Bridge would impact traffic over US 181, which was estimated to be approximately 190 trucks during weekday, daytime period. Diverting these trucks over the Joe Fulton Corridor would increase the hazmat truck traffic levels on the corridor from the current levels of between 20 to 40 trucks per weekday, daytime period to over 200 hazmat trucks per weekday, daytime period. It would also increase the distances traveled by trucks that have origins or destinations at facilities in the south Ship Channel area. It is possible that the number of hazmat truck accidents in the area might actually increase due to increased distances travelled, but the consequences of a given accident might decrease because of the nature of the roadway (lower-speed roads at grade as opposed to higher-speed roads above grade) and the distances from residential areas or activity centers.

The risk tradeoffs between route alternatives can be quantitatively estimated, and are a necessary component of hazmat route determinations. As described previously, these calculations are determined by traffic levels, material characteristics, route characteristics, accident rates, release mechanisms, population proximity, response capabilities, and distances travelled. Quantitative risk assessment is a necessary but only partial component of a NRHM routing study. The required components of a routing study are listed in 49 CFR Part 397, Subpart C. Based on the federal regulations, criteria and guidelines for conducting a hazmat routing study, including quantitative risk assessments, are described in Highway Routing of

Hazardous Materials: Guidelines for Applying Criteria, published by the U.S. Department of Transportation, Federal Highway Administration.

This study provides information about hazmat truck traffic levels in the Corpus Christi Ship Channel area, the types of hazardous materials being transported, and their hazards, which are important components of risk calculations. Route characteristics, accident rates, release mechanisms, population proximity, and response capability information can all be determined from analysis of existing data or other secondary sources (such as previous studies). However, due to the lack of information about hazmat shipment origins and destinations for hazmat trucks in the Corpus Christi area, it is not possible to determine the affected distances that would need to be travelled, or the roadways—other than the Joe Fulton Corridor—most likely to be utilized due to a Harbor Bridge hazmat truck traffic restriction.

5.3. RECOMMENDATIONS

We recommend that the LEPC, emergency planners and responders, and other interested parties:

Review the findings of this study, Evaluate the status of current and future response and community preparedness, and Identify and address associated needs and gaps.

Specific and actionable recommendations are provided in the Guide for Using Hazmat

Transportation Information that accompanies this report.

With respect to planning for hazmat truck traffic over the new Harbor Bridge, our recommendation is twofold:


1. Additional data on hazmat truck traffic origins and destinations in the Corpus Christi area should be obtained and evaluated. Ideally, these data should be acquired directly from industrial facilities and shippers in Corpus Christi.

a. The LEPC could again request that facilities provide information outlined in the LEPC’s 2016 study.

b. The LEPC could request that facilities provide copies of their responses to the USDOT BTS survey. The next reporting period is 2017.

c. Pending the success of items a or b above, additional traffic observations might be collected using methods and technologies—such as interviewing truck drivers about shipment origins and destinations, using video or still image technologies, or other methods of ascertaining truck traffic patterns—to augment the observational data set collected as part of the 2016.

2. After the supplemental data collection specified in recommendation #1 above is complete, decision makers in the Corpus Christi area should conduct a risk tradeoffs analysis to determine whether a voluntary routing process for hazmat is justified based on the anticipated reduction in risk exposure.

a. This does not mean that such a restriction will be necessarily be quantitatively justified. Risk calculations are used to determine whether such a restriction is justified, and those calculations are greatly influenced by distance and population proximities to transportation routes.

b. This also does not mean that a complete route analysis study needs to be conducted. Quantitative risk analysis is a necessary but only partial component of a full hazmat routing analysis. If it appears unlikely that an alternate route designation will be warranted based on the quantitative risk assessment, then there may be no need to proceed with other elements of a full hazmat route analysis.

Steps and timing for a potential NRHM routing process are:

Step 1. Hazmat shipment origins/destination data collection and analysis 2017 Step 2. Quantitative risk tradeoffs analysis 2018 Step 3. Full routing study (as warranted under Step 2) 2019 Step 4. Route determination (as warranted under Step 3) 2020 Step 5. Implementation (as warranted under Step 4) 2021

Step 1, to take place in 2017, could include:

1. Meetings with hazmat shippers in the Corpus Christi area to discuss hazmat transportation origins/destinations and request DOT 2012 and 2017 commodity flow survey data.

2. Evaluating data provided by shippers in the Corpus Christi area and comparing that information with data collected from the LEPC’s 2016 commodity flow study, described in this report.

3. Conducting additional hazmat truck traffic data collection at locations in and around Corpus Christi to augment the 2016 LEPC commodity flow study.


Step 2, to take place in 2018, could include: 1. Reviewing TXDOT Crash Records Information System (CRIS) accident data. 2. Identifying roadway physical, behavioral, and traffic characteristics that contribute to

CMV incident risk. 3. Conducting an inventory of existing and anticipated roadway characteristics as they

pertain to roadway safety. 4. Identifying potential truck traffic safety concerns. 5. Identifying locations of critical facilities, daytime and nighttime populations, and special

populations. 6. Identifying primary CMV/Hazmat truck traffic stakeholder groups. 7. Estimating population risks due to potential hazmat transportation incidents. 8. Estimating environmental risks due to potential hazmat transportation incidents. 9. Estimating hazmat transportation incident response times and clearance times. 10. Compiling outcomes and presenting findings regarding recommendations for a full

NRHM routing study.

An outline of the process for Step 3 (full NRHM routing study), to take place in 2019 as warranted based on findings identified in Step 2, is shown in Figure 9. The process outline is from USDOT’s guidelines for conducting a NRHM routing analysis. The information obtained from Step 2 would support several of the process steps and should be updated and augmented for a full NRHM routing study, as necessary. It is also important to note that public consultation takes place early in the formal NRHM route analysis process and must include representation from local and regional stakeholders.

APPENDIX A METHODS AND APPLICATIONS

A.1. METHODS

A.1.1. Truck Observations

This report contains a lot of discussion about truck and placard observations. Data collectors observed trucks and hazmat placards on roadways at specific data collection locations. They recorded the truck configuration and type, and placard information on data sheets for each half-hour interval of data collection. The completed data sheets were then entered into Microsoft Excel spreadsheet databases by TTI, and evaluated to identify truck traffic and hazmat transportation patterns for the different roadway segments.

A.1.2. Truck Types and Configurations

'Straight' trucks are a truck in which the truck’s drive train and cabin are on the same chassis as the cargo body. Traffic data were collected for any straight trucks that were estimated to have at least an FHWA Class 5 through 7 rating (16,001 lbs. to 33,000 lbs.) or Class 3 or Class 4 (10,001-16,000 lbs.) commercial trucks (box/van, flatbed, etc. body styles.). Straight trucks also include heavy-duty trucks such as cranes, dump trucks, roll-on/roll-off bins, and concrete trucks. Class 3 or Class 4 service/utility trucks were generally not included in the truck observation counts. However, given the number of different data collectors that participated in truck observation counts, plus challenges with determining vehicle weight/class ratings in field settings at highway speeds, this lower end of truck size inclusion is a gray area.

‘Hotshot’ trucks are typically a half-ton to one-ton pickup or flatbed truck pulling a heavy-duty goose-neck trailer. Hotshot transport typically involves an individual or small business that moves industrial, construction, or energy services project-related supplies and materials on contract basis. Hotshot operations can also include ‘one-off’ transport of cargo or materials by individuals for private or commercial activity and less than truckload delivery operations. For this study, they are classified as a tractor-trailer

'Tractor-trailer' trucks are a truck in which the truck’s drive train and cabin are pulling the cargo body that is contained on trailer. Most tractor-trailers correspond to FHWA Class 8 rating or larger, having a gross vehicle weight (GVW) of 33,001 lbs. or greater. 'Multi-trailer' or tandem trucks consist of a tractor and multiple trailer combinations.

Truck body types are categorized for this report as follows:

Box/van, including basic enclosed, drop frame, step, walk-in, multistep, open top, other box configurations, as well as shipping container and curtain/oft-side body styles;

Dry bulk, for hauling of bulk dry and aggregate materials;

Flatbeds, including stake and platform trucks;

Hotshots;


Intermodal, including corrugated steel shipping containers (Intermodal), intermodal tanks, and Intermodal chassis (the chassis frame trailer without an intermodal container or tank);

NDT, or non-destructive testing trucks;

Project, typically used for energy exploration and services;

Refrigerated van, having a refrigeration unit attached to the cargo body;

Tank, including liquid/gas tanks, compressed gas tanks, and vacuum tanks;

Utility/service, including public works, power, telecommunications, and related fields.

Other trucks, including dump, low boy, automobile carrier, trailer-mounted equipment, beverage, livestock, mobile home toter, pole, logging, pulpwood, or pipe, trash garbage, or recycling, concrete mixer or pumper, crane, tow/wrecker, tractor only, and other-not-elsewhere-classified truck and truck body configurations.

Appendix B provides examples of truck types and configurations used for this report.

Hazmat placards are used to identify whether a vehicle is carrying hazardous materials, and the type of hazardous materials that are being carried. They help identify shipment information that truck configuration alone cannot. For example, Figure A.1 is a high-pressure tank trailer, typically used to transport LPG or other similar gases. However, the tank is not carrying liquefied gas, but rather gasoline, as indicated by the UN/NA 1203 placard. Relying on tank configuration alone could misidentify the material being transported. While this may not impact the daily operations of transporting this commodity, it could have very important impacts for emergency responders, the traveling public, and nearby populations if there was an incident involving this truck because some of the initial protection and emergency response procedures are very different for flammable gases and flammable liquids. For these reasons, the information provided by hazmat placards is very important.

Hazmat placards must follow the United Nations/North American (UN/NA) classification system. This system sets a common framework for identification of hazardous materials. Material names, UN/NA numbers, and initial response guidelines for first responders are described in the 2016 Emergency Response Guidebook (ERG). The ERG is a very important tool that all responders and emergency personnel should be familiar with, and it is available free from U.S. DOT.

Trucks are required to display hazmat placards for most types of materials if the total weight of hazardous materials exceeds a threshold quantity of 1,000 pounds—except for certain explosive, toxic gas, toxic inhalation hazard, or radioactive materials, which must be placarded for any amount. Trucks transporting less than the threshold quantity of hazardous materials do not require a placard, and this means that some truck shipments are carrying hazardous materials but do not have placards. This can be particularly problematic for first responders approaching the scene of a transportation incident in which shipment information not available and the cargo load is not visible.

However, placards remain the most practical and expedient way of identifying hazmat movements on roadways for the large percentage of such shipments. Data collectors observed whether trucks had placards, and if so, the type, color, pattern, and written information (numbers or letters) on the placard. Most hazmat trucks have only one placard. Because of the speed that trucks may be traveling past observation locations, placement of the placard on the vehicle, or complexity of multiple placards, it can be challenging for even experienced observers to identify placards on a vehicle.

If data recorders were not able to specifically identify a placard, they recorded that a placard was 'unknown' or identified the placard by color, such as 'red' or 'white'. Some of the hazmat placard descriptions found in Appendix C have these designations. While such descriptions reflect uncertainty about the exact nature of hazmat transportation over a segment, they accomplish two things: 1) they identify that there is hazmat traffic present, even if it cannot be fully specified and 2) they help identify locations that may be a priority for better definition of hazmat traffic in future studies.

A.2. APPLICATIONS

Appendix C contains detailed charts and tables about truck and hazmat truck traffic observations for roadway segments. Explanations about these charts and tables and suggestions for how to use them are provided below.

1. Directional truck observation duration tables. Each data collection location will have a table that summarizes the hours of directional data collection that are applicable to roadway segments at that location, by day of week. Dates on which data collection was conducted are provided below these tables. These tables apply to both roadway directions when both directions of traffic can be observed. That is, an hour of data collection on a roadway segment for which both directions were observed (e.g., NB and SB) corresponds to two hours of directional observations. This convention is used because in some locations data collection might only be done on one side of the road, but not the other, especially on Interstate or U.S. highways.

How to use directional truck observation duration tables: These tables can provide the reader with an idea about the representativeness and comprehensiveness of the reported observations. Care should still be taken in interpreting results where data collection is limited. For some locations, around a dozen or fewer hours of directional data total were collected during all


times of day, and/or only one or two different dates might be represented. While these observations provide some indication of truck traffic at the location, planners/responders may want to evaluate whether these patterns are consistent throughout the week or at other times of day. Note that most data collection took place in the spring and summer. Planners/responders should evaluate whether traffic observations apply to fall and winter as well.

2. Average number of placarded trucks per hour charts. Where we felt that sufficient observational data was available to provide a meaningful indication of placarded truck traffic levels, we reported the information in a chart. These are based on average number of trucks observed with placards during reported time periods –on weekdays and during daytime hours. For example, if four directional hours of data were collected from 2 p.m. to 3 p.m., say on a Tuesday and a Thursday, the number of placarded trucks for that period was averaged for both days. In some cases, the charts only cover a few hours of the day.

How to use average number of placarded trucks per hour charts: These charts can provide the reader with an idea about the frequency of placarded trucks per hour, an indication of the level of hazmat traffic at a location (although non-placarded trucks that might carry hazmat would not be recorded). This information can be used for risk assessments, scenarios development, and resource allocations. The reader should keep in mind the comprehensiveness and representativeness of data collection on different days and at different times, discussed under number 1 above, and the planners/responders may wish to follow up with further traffic observations, especially for locations or times where data collection was limited. The reader should also keep in mind that this information reflects only observations of placarded vehicles, but that unplacarded vehicles are not accounted for.

3. Percentages of hazmat placards by classification charts. Where we felt that sufficient observational data was available to provide a meaningful indication of hazmat classes, and/or the information was not generally duplicative of reported placard observations (discussed under number 4 below), we reported the information in a chart. These are based on the primary hazmat classifications for observed hazmat placards. Secondary classifications are not reported in this chart.

How to use percentages of hazmat placards by classification charts: These charts can provide the reader with an idea about the broad categories of hazmat placards that were observed on corresponding roadway segments. These categories can help identify potential incident impacts, appropriate response actions and necessary resources, and population protection measures. The reader should keep in mind the comprehensiveness and representativeness of data collection on different days and at different times, discussed under number 1 above, and planners/responders may wish to follow up with further traffic observations, especially for locations where data collection was limited.

4. Placard observations tables. These tables are included for every location/segment included in this report. They list the most-frequently observed hazmat placard UN/NA ID numbers or text (or general placard description – e.g., ‘Red’ – where specific information was not available), as well as count frequencies, the percentage of all placards that were observed that are represented by the particular identifier, corresponding 2012 Emergency Response Guide (ERG) number, specific material classification (including primary and subsidiary


classifications), and material name. Since some vehicles displayed multiple placards, the number of placards reflected in this table may be greater than the total number of trucks observed with placards (discussed in number 5, below).5

How to use placard observations tables: These tables provide the reader with specific hazmat placard identifiers that were observed on corresponding roadway segments. This information goes beyond broad hazmat classifications and can help identify potential incident impacts, appropriate response actions and necessary resources, and population protection measures. Where hazmat classification charts are not provided (described in number 3 above), simply summing the percentages for each specific class in the table can provide a good indication of hazmat classification totals. If exact percentages of hazmat class are needed, the reader will also need to look up hazmat classes associated with placard ID observations listed below the tables, and sum up corresponding class percentages for all placard IDs. Note however, that for most locations/segments, the most-frequently observed placard IDs account for a majority of all observed placard IDs. The reader should keep in mind that this information reflects only observations of placards on vehicles, but that unplacarded vehicles are not accounted for. The reader should also keep in mind the comprehensiveness and representativeness of data collection on different days and at different times, discussed under number 1 above, and the planners/responders may wish to follow up with further traffic observations, especially for locations where data collection was limited.

5. Truck type/configuration and placarded truck observation tables. These tables are included for every location/segment included in this report and list the number of trucks by each configuration/type, the percent of all truck observations for each configuration/type, the number of trucks for each configuration/type that were observed with one or more hazmat placards, and the percent of each configuration/type that was observed with hazmat placards. The truck configurations used are straight truck, tractor-trailer, and multi-trailer. The truck types used are box (van), container, dry tank, flatbed, hotshot, other, pickup (straight truck only), project, refrigerated (van), tank, and utility/service. We use these configurations because they are, in our experience, breaking points for truck types that are typically observed with hazmat placards. Examples of truck types and configurations are provided in Appendix B.

How to use truck type/configuration and placarded truck observation tables: These tables can help provide the reader with an idea of which truck configuration/types were most-frequently observed, and which configurations/types were most-frequently observed with hazmat placards. This information is applicable to general risk assessments, identifying potential incident impacts, and scenarios development. It may also be applicable to transportation planning assessments, as some trucks may be more likely than others to be

5 Information about ERG numbers associated with placard IDs was obtained from Transport Canada’s Identification Number Index Web page (http://wwwapps.tc.gc.ca/saf-sec-sur/3/erg-gmu/erg/idindex.aspx) or the U.S. National Oceanic Atmospheric Administration CAMEO Chemicals database (www.cameochemicals.noaa.gov) Information about specific material classifications and material name was obtained from UPS Chemical Table downloads for ground and air shipments, version date April 1, 2012 (http://www.ups.com/media/en/chemical_table_04012012_2.pdf) or from the NOAA CAMEO Chemicals database. Where indicated, material names identify whether technical names are required for shipping purposes.

are also used. Photo by Texas A&M Transportation Institute.

Sometimes the same type of truck (e.g., tank, flatbed, or box) may have different percentages of truck configurations that are placarded (e.g., straight, tractor-trailer, or multi-trailer, as applicable). The truck configuration/type and percent placarded information can help provide a sense of a relative risk of an incident involving a hazmat-placarded vehicle. Note that percentages for percentages of pickup trucks are understated and percentages of pickup trucks with placards are overstated, as only placarded pickup trucks were recorded. Also, numbers


for utility/service vans are of limited reliability, as different data recorders often have different standards for what counts as a recordable utility/service vehicle. These tables are not direct indicators of the levels of truck traffic during a given time period (see number 6 below), since the durations of data collection at different locations varied.

Keep in mind that the national average for percentage of truck miles driven that require a hazmat placard is around 4-5 percent (slightly different from a direct measure of placarded vehicles). The reader should also keep in mind the comprehensiveness and representativeness of data collection on different days and at different times, discussed under number 1 above, and planners/responders may wish to follow up with further traffic observations, especially for locations where data collection was limited. This information reflects only observations of placards on vehicles, but unplacarded vehicles are not accounted for.

6. Truck traffic charts. Where we felt that sufficient observational data was available to provide a meaningful indication of truck traffic patterns, we reported the information in a chart for applicable data collection timeframes. These are based on average number of trucks observed during reported time periods – typically on weekdays and during daytime hours. For example, if four directional hours of data were collected from 2 p.m. to 3 p.m., say on a Tuesday and a Thursday, the number of trucks for that period was averaged for both days. In some cases, the charts only cover a few hours of the day. Second-order trend lines are sometimes provided to provide a general indication of overall and directional truck traffic patterns, however, these trend lines are not always good indicators of mid-day drops in truck traffic due to lunch-breaks. The charts also may indicate estimates of truck traffic levels for daytime (8 a.m. to 5 p.m.) periods, including directional estimates.

How to use truck traffic charts: These charts can provide the reader with an idea about the overall levels of truck traffic at a given location/segment. This information can be used for scenarios development, identify times of conflicts with passenger vehicle traffic, as well as for general emergency response/transportation/community planning assessments. The charts can help identify peaks and lows in truck traffic patterns, and associated times where truck traffic incidents may be more likely or where truck traffic may coincide with peaks in passenger vehicle traffic. They are not indicators of relative risk of an incident involving placarded trucks (although levels of placarded trucks often follow similar general patterns). The reader should keep in mind the comprehensiveness and representativeness of data collection on different days and at different times, discussed under number 1 above, and the planners/responders may wish to follow up with further traffic observations, especially for locations or times where data collection was limited.

identify when conflicts with passenger traffic are likely to occur. This information can also be used for transportation planning, including infrastructure impact assessments. Photo by Texas

A&M Transportation Institute.

Remember that truck traffic volume and hazmat percentage estimates provided in this report only represent the average values for the dates and times when data were collected. The values listed do not necessarily represent hourly, daily, or seasonal truck traffic patterns on these segments at any given time. They are intended to reduce uncertainty (not eliminate it altogether!) about what may occur, given that conditions do not change from the times of observation. It is assumed that traffic levels remain consistent over a road segment with no gains or losses of truck traffic.

We suggest that emergency planners and responders who are responsible for public safety along different corridors review and evaluate the ‘big picture’ about what the information means. When reviewing the information for these roadway segments, think about the types of transport these roads service: Are they primarily through routes? Do they serve as connectors to facilities that are sources and consumers of hazardous materials? Do the observations confirm expectations about hazmat transport, or was there hazmat traffic that was not expected? Is the truck and hazmat traffic likely to change in different seasons of the year? How can the information be used to enhance emergency planning, training, and response?

APPENDIX B TRUCK TYPE AND CONFIGURATION EXAMPLES

B.1 BOX/VAN TRUCKS

The box/van truck is comprised of a single unit with a cab and attached box or a tractor and a semi-trailer. The sizes of van trucks counted in the HMCFS ranged from small straight trucks to tractors with 53-foot trailers. Figures B.1 and B.2 are two examples of box/van cargo body configurations.

Figure B.2. Tractor–trailer box/van truck.



B.2 DRY TANK/BULK AGGREGATE TRUCKS

Bulk aggregate (bulk) trucks are trucks that hold up to approximately 50,000 lbs. of dry bulk aggregate. Almost all bulk trucks are composed of a tractor and a dry bulk container. However, the trailer can contain more axels to accommodate better weight distribution. Only a low percentage of bulk aggregate trucks are used for transporting hazmat. Figure B.3 shows a typical bulk truck.

Figure B.3. Bulk aggregate hauler.


B.3 FLATBED TRUCKS

Flatbed trucks, also known as platform trucks, consist of a tractor and a heavy-duty tandem axel platform. Straight flatbed trucks are also common. The platform varies in length and is often composed of an I-beam on 18” centers. The edge of the platform is often equipped with pockets for the addition of side stakes. Flatbeds are often used to transport equipment, pipe or steel, and/or agricultural products (grass, fertilizer, or hay bales). Flatbeds can also be seen carrying hazmat as well. Figures B.4 and B.5 are examples of flatbed trucks with different configurations.

Figure B.4. Straight flatbed (stake truck) with hazmat placards.



Figure B.5. Tractor-trailer flatbed.


B.4 HOTSHOTS

A hotshot truck is typically a diesel-powered, dual-wheeled pickup truck that is set up to haul a gooseneck trailer. Hotshot trucks are typically commercial for-hire motor carriers that transport freight and are normally limited to 36,000 pounds gross weight. Hotshot trucks are independently owned and operated, or they may be leased to a larger trucking company. They typically are used for specialty or lighter loads that do not require a full size tractor-trailer.

Figure B.6. Hotshot truck/trailer.


B.5 PROJECT TRUCKS

Project trucks for the purpose of this study are trucks that are built for a specific purpose or to haul a specialty load. For example, a number of trucks designed to haul oil field or well support services can be classified as project trucks. They may include fracking related trucks as depicted in Figure B.7, special equipment haulers shown in Figure B.8, or Drilling Fluids trucks, Figure B.9. Other trucks not shown that may be classified as project trucks included rig haulers, hot oiling trucks, specialty well cementing trucks, coil tubers, swab trucks, and trucks that carry blow out prevention equipment.


Figure B.7. Project truck.






B.6 REFRIGERATED VAN TRUCKS

The refrigerated van truck is very similar to the standard van truck previously described. The difference between a standard and refrigerated van truck is the refrigeration unit on the front of the semi-trailer located between the trailer and the tractor/cab. The trailer is also insulated and cooled by the refrigeration unit. Sizes counted for the study ranged from single unit refrigerated trucks to tractors and semi-trailers. Figure B.10 is an example of a refrigerated van truck.


Figure B.10. Tractor-trailer refrigerated van truck.


B.7 TANK TRUCKS

Tank trucks usually consist of a straight tank truck or tractor and a tank trailer in a 3-S2 configuration. Different configurations of tank trailers hold different capacities of materials (see Table B.1 for capacity analysis). Tank trucks are normally between 41 to 43 feet in length, 8 feet in width, and cylindrical in shape. The tractor-trailers are made from various materials depending on the commodity they are hauling, and they have various capacities. Many trailers are made from steel or aluminum. Tank trailers are can often be seen transporting hazardous materials, such as gasoline, propane, chlorine, and compressed gas. Vacuum tankers are also common in some areas. Vacuum tankers carry liquids (including hazmat) under the pressure of a vacuum. Figures B.11, B.12, B.13, B.14 and B.15 show three different types of tank trucks.

B.8 UTILITY/SERVICE TRUCKS

Utility and service trucks are usually straight trucks with 2-to-4 axels. There are many different sizes of utility trucks. Utility trucks are used for the service and maintenance of city utilities including water, sewage, and electricity. Service trucks are used for oilfield or other project related service activities. Figures B.16 is an example of a utility/service truck.

B.9 OTHER TRUCKS

Trucks that did not match the criteria of the eight categories previously mentioned were placed into the “other trucks” category. These truck body types included, but were not limited to: dump, crane, roll-off/waste management, tow, livestock, auto, ready-mix, and log trucks. Trucks placed in the other category were both classified as large and small types. Some trucks in the other category displayed hazmat placards. The figures below are examples of trucks placed into the “other” category.

NON-DESTRUCTIVE TESTING SERVICE (NDT) VEHICLES

Description: X-ray/radiography and non-destructive testing vehicles, like the one pictured below, may contain radioactive sources and may or may not be placarded for radioactive materials. These vehicles are typically a standard pickup truck with a tall box in the bed and often are white or light colored. These bed boxes resemble a windowless “camper shell” with a door in the back, and usually have an air conditioner unit and/or generator mounted on them. Vehicles will typically be marked with a company name and/or logo includes the words “testing,” “NDT,” or “inspection.”

Non-Destructive Test vehicle / Radiation shipping labels. (Sources: TTI and ndt.org). Caution: If one of these vehicles is involved in a roadway accident, it is important to assess

whether these vehicles contain radioactive source material. Usually, these sources are contained in a shielded device, camera, or container that, if intact, poses no threat. However, if an accident breaches the shielding/container, the exposed source may pose a significant radiation hazard.

Case Markings: (See picture above) Source containers and/or equipment are marked with a label denoting their radiation level if intact/undamaged.

Radioactive White I: 0.5 mrem/hr max. on surface Radioactive Yellow II: 50 mrem/hr max. on surface; 1 mrem/hr max. at 1 meter Radioactive Yellow III: 200 mrem/hr max. on surface; 10 mrem/hr max. at 1

meter

Response: Do not approach exposed material or damaged equipment. Isolate the immediate vicinity of the accident and consult your departmental policy for hazardous materials response involving radioactive material. See also the Emergency Response Guidebook (ERG), Guide # 163 (radioactive material).

Safety: Remember the principles of time, distance, and shielding.

Time: Limit the time you expose yourself to a radiation source.

Distance: Maintain a safe distance. You do not have to get very far away from a source, even a highly radioactive one, to be safe. Remember: Double the distance, quarter the dose. If a source emits 10 rem of gamma radiation one foot from the source, the dose will be 2.5 rem at two feet. For serious radiological accidents, the ERG initial isolation zone is 100 meters.

Shielding: Place yourself so that solid objects, like vehicles or buildings, are directly between you and the radiation source.
