Welcome to EPA's Risk-Screening Environmental
Indicators Model

EPA's Risk-Screening Environmental Indicators (RSEI) is a PC-based tool that uses risk
concepts to quickly and easily screen large amounts of Toxics Release Inventory data, saving
time and resources. RSEI users can perform, usually in a matter of minutes, a variety of
screening-level analyses. Previously, such activities would have taken days, weeks, or even
months to organize the relevant information, evaluate that information, and perform the
complex and sophisticated analyses that are necessary to provide a risk-related perspective.
RSEI is particularly useful for examining trends to measure change, and ranking and
prioritizing chemicals and industry sectors for strategic planning, conducting risk-related
targeting, and supporting community-based projects. Considerable resources can be saved by
conducting preliminary analyses with the model to identify risk-related situations of high
potential concern, which warrant further evaluation.

RSEI permits full risk-related modeling for air (on-site stack, fugitive and off-site incineration)
releases and surface water releases (direct from TRI reporting facilities and POTWs) only.
However, all releases and transfers reported to TRI can be viewed from pounds-only and
hazard-based (pounds weighted by toxicity) perspectives. This User's Manual provides
instructions specific to the use of the current version of the model, and also describes some
additional functions that are not implemented in the current air- and surface water-only model.

In addition to caveats listed throughout this User's Manual, there are several things to consider
when running the current version of the model:

•	When installing the RSEI model, please make sure that you sign
off of your computer network (e.g., the Novell network), so that
the model will be properly installed onto your computer's hard
drive. Furthermore, the user must have administration rights on
the local computer.

•	Because the current version of the model is restricted to the air
and surface water modeling results, the full risk-related model
results are available only for on-site fugitive and stack air releases
and direct surface water releases; risk-related results based on
releases to other media (e.g., releases to groundwater) are not
available. However, with this version of the model you will be
able to look at TRI pounds, modeled pounds, hazard ranking, and
subcomponents of the full risk-related model results, e.g., (pounds
* toxicity) and (pounds * toxicity * population) for all media.

•	Please be aware that the application uses significant computer

resources. It may be difficult to use other computer applications at
the same time as RSEI.

•	The model contains TRI release and transfer information for the
time period from reporting years 1996 to 2010. Information from
the reporting years 1988 through 1995 is available upon request.

•	Information presented in these Help Screens is also available in
the User's Manual.

•	New users are advised to begin with the Tutorials provided in
Chapter 4 of the User's Manual, which are a helpful introduction
to the RSEI model. They are also available through the model by
clicking on the Tutorial button on the first screen of the model.

We would appreciate your comments and suggestions on how these Help Screens may be
improved upon to aid you, the user. Thank you.

Introduction

EPA's Risk-Screening Environmental Indicators (RSEI) model is a screening-level tool that
assesses the potential impact of industrial chemical releases from pounds-based, hazard-based,
and risk-related perspectives. RSEI uses risk concepts to quickly and easily screen large
amounts of data, saving time and resources. RSEI is particularly useful for examining trends to
measure change, ranking and prioritizing chemicals and industry sectors for strategic planning,
conducting risk-related targeting, and supporting community-based projects.

Using estimates of pounds of chemical releases to investigate potential health and
environmental impact is limited by the assumptions that all chemicals are equally toxic and all
people are equally exposed. Formal risk assessments are more accurate, but are complicated
and time-consuming to prepare, requiring detailed data which are not always available, and the
results are often limited in scope and geographic area. The RSEI approach augments estimates
of pounds released with toxicity and exposure considerations, but does not address all of the
potential factors that a full risk assessment would include.

RSEI considers the following information: the amount of chemical released, the toxicity of the
chemical, its fate and transport through the environment, the route and extent of human
exposure, and the number of people affected. This information is used to create numerical
values that can be added and compared in limitless ways to assess the relative risk of chemicals,
facilities, regions, industries, or many other factors. The values are for comparative purposes

and only meaningful when compared to other values produced by RSEI. It should be
emphasized that the result is not a detailed or quantitative risk assessment, but offers a
screening-level, risk-related perspective for relative comparisons of chemical releases.

The RSEI approach is very flexible and can be implemented in various ways. The use of the
model is not limited to TRI chemicals; in principle, the adaptable method can model any
chemical if toxicity characteristics, physicochemical properties, release levels, and release
location are known or can be estimated. The current version of the model addresses chronic
human health effects and chronic exposures, and uses estimates of annual releases from EPA's
Toxics Release Inventory (TRI).

As an indication of improvements in environmental quality over time, RSEI provides a
valuable tool to measure general trends based upon relative risk-related impacts of TRI
chemicals. Although the model results do not capture all environmental releases of concern,
they do relate changes in releases to relative changes in chronic human health impacts from a
large number of toxic chemicals of concern to the Agency. The model also can analyze the
relative contribution of chemicals and industrial sectors to environmental impacts, and serves
as an analytical basis for further risk analysis, setting priorities for pollution prevention,
regulatory initiatives, enforcement targeting, and chemical testing.

The following sections of this chapter describe the RSEI method and the types of questions
that can be explored using the model. Chapter 3 describes the main features of Version 2.
Chapter 4 provides three tutorials that will help the new user get started with commonly-used
functions. Chapters 5 through 9 describe in detail the operations of the model. Chapter 10
provides information that may be useful when querying the database, including SIC and NAICS
codes, score category codes, FIPS codes, and a glossary. Technical Appendices can also be
found on the RSEI Installation Disk in a folder called 'Supporting Information.' The
appendices present additional information on the following topics: toxicity (Appendix A) and
physicochemical data (Appendix B) for TRI chemicals, exposure assumptions used in the
model (Appendix C), locational data for on-site and off-site facilities (Appendix D), derived
stack parameter data (Appendix E), and data differences between TRI and the RSEI model
(Appendix F). A spreadsheet detailing the calculation of the chemical toxicity weights used in
the model is also provided on the Installation Disk.

Geographic Basis of the Model

The RSEI model relies on the ability to locate facilities and people geographically, and to
attribute physical characteristics, such as meteorology, to the facilities once they are located. To
locate the facilities and the attribute data to those facilities, the RSEI model describes the
United States and its territories (Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa,
and the Northern Mariana Islands) as a 810-m by 810-m grid system. For each cell in the grid, a
location address in terms of (X,Y) coordinates is assigned based on latitude and longitude (lat/
long).

RSEI uses a standard Albers Equal-Area projection to create each of the grids that is used in the
model. The grid system is split into six individual grids which cover the continental U.S.,
Alaska, Hawaii, and the territories. Each unique cell address is composed of (1) the grid

Version 2.3.1

-------
CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

number, and (2) the (x,y) address of the cell in that grid. The Methodology document provides
the grid number (used in the model to identify each grid), the grid characteristics that can be
used to recreate the grid in a GIS-based system, and the bounding coordinates for each.

Once the grid system for the U.S. is established, facilities can be located in it. The ability of the
RSEI model to accurately locate a facility depends on the accuracy of the lat/long coordinates
describing its location. RSEI uses the best set of coordinates for each facility from EPA's
Locational Reference Tables (LRT). Facilities are projected onto each grid using GIS software
and the (x,y) coordinates of the cell where the facility is mapped are assigned to the facility.
Once a grid cell's (x,^) coordinates are assigned, the facility is assumed to be at the cell's
center, for ease of modeling. For a complete description of the method used to select lat/long
coordinates for both reporting facilities and off-site facilities, see Technical Appendix D.

In order to estimate potential exposure, the U.S. population must also be geographically located
on the model grid. The RSEI model uses decennial U.S. Census data for 1990, 2000, and 2010
at the block level (Census data provided by GeoLytics, Inc., East Brunswick, NJ). In previous
versions of the model, U.S. Census race categories were available for viewing on the map (not
for calculating results). However, due to complications arising from changes in race
categorization for the 2000 Census, race categories are not available for viewing in the current
version of the model. The following sections describe how the U.S. Census data were used to
generate annual population estimates for age and sex, and how the unit of analysis for the U.S.
Census (the block) is translated into the unit of analysis for the model (the grid cell).

Population data. U.S. Census block-level data are used to estimate the number of people in
each grid cell, as well as their demographic characteristics. Census blocks are the smallest
geographic area for which decennial census data are collected. Blocks are of varying size,
formed by streets, roads, railroads, streams and other bodies of water, other visible physical and
cultural features, and the legal boundaries shown on Census Bureau maps. In 1990, there were
approximately 7 million census blocks. Due to boundary changes and increased resolution for
highly populated areas, there were approximately 9 million blocks in the 2000 Census and more
than 11 million in the 2010 Census.

Block-level information from the 1990, 2000, and 2010 Censuses are used to create detailed
age-sex variables for each of the census blocks in the US for 1990, 2000, and 2010. (For 1990,
not all of the variables were available at the block level. For those variables that were only
available at the block group level, block group ratios were calculated and applied to the data at
the block level. For 2000 and 2010, all of the required data for the continental US and Puerto
Rico were available at the block level.) The following variables are available in the RSEI
model:

•	Males Aged 0 through 9 years

•	Males Aged 10 through 17 years

•	Males Aged 18 through 44 years

•	Males Aged 45 through 64 years (Results for this subpopulation are not displayed separately
in the model)

•	Males Aged 65 years and Older

Version 2.3.1

•	Females Aged 0 through 9 years

•	Females Aged 10 through 17 years

•	Females Aged 18 through 44 years

•	Females Aged 45 through 64 years (Results for this subpopulation are not displayed
separately in the model)

•	Females Aged 65 years and Older

Because the Census block boundaries have changed between Censuses, the block level data are
first transferred to the RSEI model grid, which is unchanging, using the method described
below in Mapping block populations to grid cells. Once on the grid, a straight-line
interpolation is performed for each grid cell between 1990 to 2000 to create annual estimates of
the population for each grid cell for each year. The straight line is also extended to estimate
population for 1988 and 1989. Another line is extended between 2000 and 2010 to estimate the
years in between.

Puerto Rico and Territories. For Puerto Rico, the U.S. Virgin Islands, American Samoa,
Guam, and the Northern Mariana Islands, block-level shapefiles and block-level population
data were only available for 2000. For 1990, the grid cell-level populations from 2000 were
scaled by age-sex specific Census population estimates for 1990 to create 1990 population
estimates. For 2010, block-level population was only available for Puerto Rico; for the other
areas, similar age-sex specific Census data from 2010 were used to scale the 2000 data to create
2010 population estimates. Grid cells for Puerto Rico and island areas are mapped in the same
way as described below.

Mapping block populations to grid cells. Once annual detailed demographic data sets are
created, the model translates the data from Census blocks to the model's 810-m by 810-m grid
cells. The Census provides the geometry for each block in the Topologically Integrated
Geographic Encoding and Referencing (TIGER) geographic database. The boundaries and area
for each block were derived from the TIGER database. The location of each grid cell is defined
by its four corner points, calculated from its (x,y) coordinates. The RSEI model uses the derived
block boundary files to map each block to its corresponding cells in the grid according to the
portion of the block's total area that falls within each cell. The area of a block that falls within a
grid cell is divided by the total area for that block, then that fraction is multiplied by the block's
population and subpopulations to determine its contribution to the grid cell's population. The
population is assumed to be distributed evenly throughout the block. If more than one block
overlays a grid cell, then the populations contributed by the multiple blocks are summed.

Model Description

The RSEI Chronic Human Health model calculates values that reflect the risk-related impacts
on chronic human health of modeled TRI chemical releases and transfers. These values do not
provide absolute measures of risk and can only be interpreted as relative measures to be
compared with other such values (reflecting the direction and the general magnitude of changes
at different points in time when analyzing trends, or identifying the relative contribution of
variables in a comparative analysis).

CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

The model uses the reported quantities of TRI releases and transfers of chemicals to estimate
the risk-related impacts associated with each type of air or water release or transfer by every
TRI facility. The risk-related impacts potentially posed by a chemical are a function of
chemical toxicity, the fate and transport of the chemical in the environment after it is released,
the pathway of human exposure, and the number of people exposed. RSEI only analyzes the
impacts on general populations; individuals, particularly highly exposed individuals, are not the
focus of the model.

The RSEI model starts with TRI releases. For each exposure pathway from each chemical
release, the model generates an 'Indicator Element'. For instance, a release of the chemical
benzene to air via a stack from the 'ABC' Facility in 1999 is an 'Indicator Element'. Each
Indicator Element is associated with a set of results, including pounds-based, hazard-based,
and risk-related results, also called scores. The risk-related score is a unitless value proportional
to the potential risk-related impact of each element.

Each Indicator Element can be combined and compared with other Indicator Elements. There
are countless ways that Indicator Elements can be summed together to assess chronic human
health impacts. For example, all of the RSEI results can be aggregated for each year to allow an
assessment of trends in estimated impacts, or Indicator Elements can be summed to allow users
to compare results for facilities, regions, chemicals, and any combinations of these and other
variables. RSEI does not perform a detailed or quantitative risk assessment, but offers a
screening-level, risk-related perspective for relative comparisons of chemical releases. The
model does not estimate actual risk to individuals. RSEI results are only meaningful when
compared to other results produced by RSEI.

The current version of the model calculates risk-related results for the air and surface water
pathways only. For other pathways, and in instances where information needed to model a
release is not available, only pounds-based and hazard-based perspectives are available. In
cases where toxicity weights are not available, only pounds-based results can be viewed.

In addition, RSEI allows users to look at pounds- and hazard-based results using the same kinds
of combinations and comparisons. For a detailed description of the RSEI model and
components of the model, refer to EPA's Risk-Screening Environmental Indicators
Methodology (available on the RSEI website at http://www.epa.gov/oppt/rsei), which
represents the most recent full documentation of the model.

Components of the Model

Once facilities and people are located on the model's grid, three main components are used to
compute risk-related impacts in the RSEI model. These components are:

•	the quantity of chemicals released or transferred,

•	adjustments for chronic human health toxicity,

•	adjustments for exposure potential and population size

These components and the method used to combine them are described in the following
sections.

Version 2.3.1

1996-2010 TRI Data

CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

Chemical Releases and Transfers

The model uses information on facilities' chemical releases and transfers from these facilities
to off-site facilities (such as sewage treatment plants and incinerators) to model risk-related
impacts. These releases are reported by facilities to the Toxics Release Inventory (TRI), as
mandated by the Emergency Planning and Community Right-to-Know Act (EPCRA). As of the
2010 reporting year, there are 611 TRI chemicals and chemical categories listed. Users can
view pounds of chemicals released per year (pounds-based results) for any combination of
variables included in the model.

Adjustments for Chronic Human Health Toxicity

The model is based on current EPA methodologies for assessing toxicity. The method EPA has
chosen for assigning toxicity weights to chemicals is clear and reproducible, based upon easily
accessible and publicly available information, and uses expert EPA-wide judgments to the
greatest extent possible. RSEI reflects the toxicities of chemicals relative to one another using a
continuous system of numerical weights. Toxicity weights for chemicals increase as the
toxicological potential to cause chronic human health effects increases. Toxicity-adjusted
releases are called "hazard-based results" and provide an alternative perspective to
pounds-based or full risk-related results, and are especially valuable when necessary data for
risk-related modeling are not available.

Toxicity Data

Values developed by EPA experts are used to differentiate the
degrees and types of toxicity of chemicals and rank them in a
consistent manner. Values called Oral Slope Factors and Inhalation
Unit Risks provide information pertaining to toxicity for chemicals
that may cause cancer. Reference Doses (RfDs) and Reference
Concentrations (RfCs) provide toxicity information related to
noncancer effects. Where these values are not available from EPA,
other data sources may be used.

The following data sources are used, in the order of preference:

•	EPA's Integrated Risk Information System (IRIS);

•	EPA Office of Pesticide Programs' Toxicity Tracking Reports (OPP) and Pesticide
Reregi strati on Elegibility Documents (REDs);

•	Agency for Toxic Substances and Disease Registry final, published chronic MRLs
(AT SDR);

•	California Environmental Protection Agency's Office of Environmental Health Hazard
Assessment final, published toxicity values (Cal/EPA);

•	EPA's Provisional Peer Reviewed Toxicity Values (PPRTVs), which include toxicity
values that have been developed by EPA's Office of Research and Development/National
Center for Environmental Assessment/Superfund Health Risk Technical Support Center

(STSC);

•	EPA's Health Effects Assessment Summary Tables (HEAST); and

•	Final Derived/Interim Derived Toxicity Weights (Derived) estimated by EPA's Office of
Pollution Prevention and Toxics.

The data sources are used in a tiered fashion. The first tier consists of IRIS and OPP. The most
recent data for each chemical's chronic human health endpoint is used. If the dates are
comparable, preference is given to IRIS. The second tier consists of ATSDR and Cal/EPA.
Again, the most recent source of the two is used for any chemical's chronic human health
endpoint not found in the first tier. In the absence of data from first or second tier sources for an
individual chronic health endpoint, the following data sources are used, in the order of
preference: PPRTVs, HEAST, Final/Interim Derived, and IRIS values previously used in
toxicity weighting, but withdrawn pending revision.

For chemicals with carcinogenicity risk values, Weight of Evidence (WOE) values were
obtained using the same data source hierarchy. Therefore, preference was given to WOE's from
IRIS or OPP. As a general rule, chemicals with cancer potency factors from IRIS or OPP will
also have WOEs. CalEPA, however, references either EPA or IARC for WOE designations.
Therefore, in the absence of an EPA consensus WOE, WOE's were obtained from the
International Agency for Research on Cancer (IARC). However, due to the differences in WOE
definition, it is not always possible to translate IARC WOE's into EPA WOE's without
examining the toxicity data. WOE's were matched in the following way:

•	IARC Group 1 = EPA Group A (Human Carcinogen)

•	IARC Group 2A = EPA Group B (Probable Human Carcinogen)

•	IARC Group 2B = EPA Group B or EPA Group C (Possible Carcinogen)

•	IARC Group 3 = EPA Group D (Not Classifiable as to Human Carcinogenicity)

•	IARC Group 4 = EPA Group E (Evidence of Non-Carcinogenicity)

The IARC 2B designation is not easily translated to the EPA designation, and spans EPA
Groups B and C. This is a particularly important distinction because the use of a B2 or C
designation will affect the calculation of the toxicity weight (see below). Therefore, for the
chemicals with IARC 2B designations, summaries of the toxicity data used to generate the oral
slope factor or inhalation unit risk were evaluated to derive WOEs. Since these are primarily
chemicals with data from CalEPA, the CalEPA "Technical Support Document for Describing
Available Cancer Potency Factors" was used for the background information.

CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

Calculating Toxicity Weights

The RSEI toxicity scoring method evaluates inhalation and oral exposure routes for both cancer
and noncancer effects. For each exposure route, chemicals are scored based on their single most
sensitive adverse effect. For the various noncancer health endpoints, the toxicity weighting
methodology does not distinguish between chemicals based on type or target of effect (e.g.,
neurotoxicity vs. developmental toxicity), nor does it address multiple effects which may be
exhibited by a chemical. When values are available for only one route of exposure, the same
toxicity weight is applied to reflect the potential for both inhalation and oral toxicity, provided
there is no evidence the effects are route-specific or limited to the portal of entry into the body.
Specifically, in limited instances, toxicity studies are available to show a given chemical causes
no health effects by one exposure route. In these instances, a toxicity weight is assigned only to
the route that results in chronic human health effects. In the RSEI methodology, the algorithms
shown below are used to assign toxicity weights.

The distribution of toxicity values for TRI chemicals corresponds to a range of toxicity weights
of approximately 0.02 to 500,000,000. However, toxicity weights are not bounded. Toxicity
weights are expressed as values with two significant figures.

There are 611 chemicals and chemical categories on the 2010 TRI Chemical List. Toxicity
weights are available for 430 of these chemicals and chemical categories. The 430 chemicals
with toxicity weights account for over 99% of the reported pounds for all on-site releases in
2010. Beginning with version 2.1.5, each metal compounds category is combined with its
elemental form in RSEI, unlike in TRI where they are reported separately. This is done to
reflect the uncertainty of the chemical identity of the substance released. For example, TRI has
separate reporting for 'nickel' and 'nickel compounds'. Both reflect the pounds of the parent
metal nickel that is released and, in some cases, the two can be combined as a single report for
nickel compounds. RSEI combines the pounds into one entry listed as 'nickel and nickel
compounds'.

More information on the toxicity data used in the model can be found in Technical Appendix
A. A complete discussion of the methods used in these evaluations, as well as the
chemical-by-chemical data summaries and score assignments, are provided the Toxicity

Weighting Methodology document, which can be found on the RSEI website
(www.epa.gov/oppt/rsei).

Adjustments for Exposure Potential

Quantitatively, exposure potential is estimated using a surrogate dose. To estimate the surrogate
dose, a separate exposure evaluation is conducted for each pathway-specific chemical emission.
The exposure evaluations use models that incorporate data on media- and pathway-specific
chemical releases and transfers, physicochemical properties and, where available, site
characteristics, to estimate the ambient chemical concentration in the medium into which the
chemical is released or transferred. The ambient concentrations are combined with human
exposure assumptions and estimates of exposed population size specific to age and sex.

Specific exposure factors are discussed in each section below.

The algorithms for calculating surrogate doses rely on the ability to locate facilities and people
geographically on the 810-m by 810-m grid cell system described earlier. While this method
uses the EPA exposure assessment paradigm to evaluate exposure potential, the results should
not be construed as an actual numerical estimate of dose resulting from TRI releases, because
limited facility-specific data and the use of models that rely on default values for many
parameters prevent the calculation of an actual dose. Instead, the purpose of the methodology is
to generate as accurate a surrogate dose as possible without conducting an in-depth risk
assessment. The estimates of surrogate doses from releases of TRI chemicals are relative to the
surrogate doses resulting from other releases included in the model.

The sections below discuss each of the exposure pathways included in the model. Please note
that not all pathways are currently modeled in the RSEI model. For pathways that are not
modeled, risk-related results are not available, but users can examine results from pounds-based
and hazard-based perspectives.

Stack and Fugitive Air Releases

This method uses algorithms from EPA's AERMOD model, developed by the Office of Air
Quality Planning and Standards (OAQPS). AERMOD is a steady-state plume model used to
estimate long-term pollutant concentrations downwind of a stack or area source. The
concentration is a function of facility-specific parameters (such as stack height and diameter),
meteorology, and chemical-specific, first-order air decay rates. The air decay rates are based on
either photooxidation or, in rare cases, hydrolysis in air.

AERMOD then uses meteorological and chemical-specific decay rates to estimate the air
concentrations at small intervals in a circle with radius 49km surrounding the grid cell
containing the facility. Air concentrations are calculated at 5 km increments from 5 km to 49
km away from the facility. Each concentration is calculated at the midpoint of the edge closest
to the source in the center cell. For the center cell in which the facility is located, the RSEI
model splits the center cell into 401 sub-cells (each sub-cell is 50 m by 50 m), and assigns the
average concentration of these sub-cells to the 810-m by 810-m center cell.

Stack height data were obtained from the National Emissions Inventory (NEI), the AIRS

CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

Facility Subsystem (AFS) within the Aerometric Information Retrieval System (AIRS), the
National Emission Trends (NET) Database, and databases from three individual states
(California, New York, and Wisconsin). For each TRI facility that had stack height data in one
or more of these sources, the median height of all stacks at the facility is used in the RSEI
model. For the TRI facilities which had no stack height data in these sources, a Standard
Industrial Classification (SIC) code-based median stack height is assigned to the facility. The
SIC code-based stack height is estimated from data in AFS and the NET Database for facilities
in the appropriate 3-digit SIC code or in the 2-digit SIC code if the 3-digit SIC code is
unavailable (based on the TRI facility's primary SIC Code). If no 2-digit SIC code is available,
the median of all stack heights with TRI-reportable SIC codes is used.

For both stack diameter and exit gas velocity, the RSEI model uses the same data sources,
criteria, and statistical methods described above for stack height data. Specifically, the model
uses either the median value of all stacks for TRI facilities with this information or a SIC
code-based median value for facilities without the appropriate stack data. Exit gas velocity data
are obtained from NEI, AFS, NET, and state-specific databases. Stack diameter data are
obtained from NEI, AFS and NET.

An additional data source was used for some of the new industries added in Reporting Year
1998. The Electric Power Research Institute (EPRI) provided EPA with two databases of
site-specific data for electric utilities, including stack height, stack diameter, and stack velocity.
Approximately 600 TRI facilities report one of the three electric utility SIC codes (4911-
Electric Services; 4931- Electric and Other Services Combined; or 4939- Combination
Utilities, not elsewhere classified). Where possible, TRI facilities were matched to facilities in
the EPRI data, and the EPRI stack parameters were used. For the facilities that could not be
matched, the median parameters from the EPRI data were used.

Analyses have been conducted that show that the concentrations predicted by the RSEI model
using a combination of generic and site-specific data closely match concentrations estimated by
using more complete site-specific data. For complete details on the derivation of stack
parameter data, see Technical Appendix E.

For air releases, chemical concentrations are calculated at increments inside a circle with radius
of 49 km surrounding the facility. The concentration is multiplied by age-sex specific
inhalation rates, as shown in Table 2 below. This calculates the surrogate dose for each of the
ten age-sex categories included in the model. The population assigned to each grid cell is
assumed to be exposed to the concentration calculated for that grid cell.

Direct Surface Water Releases

Chemicals released directly to surface waters are modeled using a simple first-order decay
equation, along with estimates of river discharge and velocity. Chemical concentrations are
estimated for distances up to 300 km downstream from the chemical release to take into
account drinking water intakes up to 300 km downstream. The chemical-specific decay
coefficient is predominantly based on either abiotic hydrolysis or microbial biodegradation, but
it may also be based on photooxidation.

This method considers two chronic human health exposure pathways from surface water
releases. First, exposures from drinking water are calculated. Chemical releases from on-site or
off-site facilities into water are assumed to be discharged into the stream reach nearest the
facility, unless a specific discharge reach has been determined from EPA data sources. As the
chemical travels downstream, concentrations at public drinking water intakes are estimated.
The number of people served by the water system supplied by the intake is assumed to be the
population exposed to the chemical concentration. However, because only the number of
people served, not their geographic location, is known, the model uses the demographic
breakdown of all the people in a 80 km radius around each intake as a surrogate for the actual
number of people in each age-sex subgroup served by the drinking water intake. Drinking water
ingestion rates are shown in Table 2 below. If a stream reach contains no drinking water intake,
the exposed population is zero. The concentrations at the drinking water intake for chemicals
for which EPA has established Maximum Contaminant Levels (MCLs) are assumed to not
exceed the relevant MCLs that were in effect for the year of the release (some information prior
to 1991 is not available, see 'MCL' in Chapter 5 for details).

A second potential exposure pathway is from consumption of contaminated fish. Each segment

CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

of the affected surface water reach may contain contaminated fish which could be caught and
eaten by recreational and subsistence fishers. As described above, the model tracks the
concentration of the chemical as it travels downstream. In each stream reach, the estimated
concentration in fish is derived by multiplying the chemical concentration in the water by a
factor to account for bioconcentration of the chemical from water into fish. County- and
state-specific fishing license data are used to estimate the percentage of people in each county
who fish. This number is multiplied by an estimate of average household size to obtain the
portion of each county's total population that eats fish. Since most fishers travel a maximum of
50 miles (80 km) to fish, the population within 50 miles (according to Census data) of a reach
modeled as having a nonzero chemical concentration is multiplied by the county-specific
fish-eating percentage to obtain the total exposed population. Recreational fishers and their
families are assumed to comprise 95 percent of this exposed population. Subsistence fishers
and families make up the remaining 5 percent. Subsistence fishers are also assumed to eat
substantially greater amounts of fish than recreational fishers, as shown in Table 3 below.

Land Releases

On- and off-site land releases include releases to landfills, surface impoundments, land
treatment units and underground injection wells. For these releases, two major exposure
pathways are of interest: volatilization to air or leaching into groundwater. Volatilization of
chemicals from on-site land releases is reported to TRI under the fugitive emission estimate for
the facility, and is handled as a fugitive air release. For more information on RSEI modeling of

Version 2.3.1

CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

fugitive air releases, see Air Releases above. The current version of RSEI does not provide risk
modeling for reported land releases. However, RSEI does provide the capability for users to
examine the pounds of releases to land that are reported to TRI, as well as viewing these
releases from a hazard-based perspective.

The potential for groundwater contamination from land releases depends on the regulatory
status of the unit in which the chemical is released. For example, chemicals could be deposited
in an on-site RCRA-regulated, subtitle C hazardous waste unit, or in an on-site nonhazardous
solid waste management unit. RCRA standards for hazardous waste units are, by regulation,
designed to include technical controls to prevent release of contaminants into groundwater. If
chemicals are placed in such regulated units, EPA assumes that releases to groundwater are
negligible so RSEI would assign a zero value to the risk-related scores for such releases. If
chemicals are placed in nonhazardous land disposal units (landfills, etc.), there is a potential for
exposure. This exposure pathway and volatilization from off-site landfills are currently under
review for inclusion in a future version of RSEI.

On- and off-site land releases to underground injection are not modeled for exposure by RSEI.
The hydrogeological, spatial, and temporal considerations that are associated with exposures to
toxic chemicals in underground injection wells are situation- and site-specific, so RSEI is only
able to provide pounds-based and hazard-based perspectives for this type of land release. Note,
however, that under well-managed conditions, Class I wells (there are five classes of wells) are
specifically designed to pose minimal risk to human health or the environment.

Releases to POTWs

On-site facilities can also transfer chemicals to Publicly-Owned Treatment Works (POTWs).
Modeling exposure from TRI-reported transfers to POTWs requires several pieces of
information: (1) location of the POTW to which the chemicals are discharged, (2) consideration
of overall removal efficiencies of POTWs and resulting effluent discharges from POTWs, (3)
consideration of residuals management at POTWs, and (4) identification of the receiving
stream reach.

Locating the POTW. As with all off-site facilities, POTW names and addresses are reported
to TRI by the facility transferring its waste. Latitude and longitude are not reported. In order to
derive coordinates, the reported street addresses were geocoded (coordinates were assigned
based on street address) by Thomas Computing Services, a commercial firm. Other EPA
databases are also used for matching as well as for locational data. Facilities with insufficient or
incorrect street addresses are matched, if possible, with facilities with better locational data. If
no matches can be found, the facility is assumed to be located at the center of its reported zip
code. Once latitude and longitude for a facility are determined, the data are used to map the
facility to a given grid cell, using the equations described in Chapter 3 of the Methodology
document. Substantial data processing was necessary to prepare the set of off-site facilities for
use in the model; see Technical Appendix D for details on the steps that were taken.

Overall POTW Removal Rate. POTWs cannot completely remove all of the chemicals that
are transferred to the plant. Some of the chemical loading in the influent will be discharged as
effluent to surface waters. To calculate the fraction of transferred chemical removed by the

Version 2.3.1
May 2012

14

1996-2010 TRI Data


-------
CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

POTW, the typical contaminant-specific removal rate is applied to the volume transferred to the
POTW from the TRI facility.

Partitioning within the POTW. Chemical loadings may be removed by the POTW treatment
processes through biodegradation, volatilization, and adsorption to sludge. The amount of the
chemical that is removed by each of these processes is modeled using average
chemical-specific partitioning rates. Chemical-specific partition rates are provided in Technical
Appendix B.

Once the fates of chemicals entering the POTW are estimated, exposures associated with
chemical loadings to each compartment are estimated. Chemicals discharged in the POTW
effluent are modeled using the surface water evaluation methods described above. Chemicals
that biodegrade are assumed to degrade to chemicals that do not pose risk. POTW volatilization
releases are treated like area-source air releases, as described above.

For chemicals that partition to sludge, the model used to estimate exposure should ideally
depend on the sludge disposal method employed by the POTW. However, sludge disposal
practices at a POTW receiving a TRI transfer cannot be determined from the TRI database.
Therefore, the RSEI algorithm currently assumes all POTW sludge to be landfilled at the
POTW, a common method of sludge disposal. Landfilling of sludge is not currently modeled in
RSEI. POTWs may in reality use other methods of sludge disposal, such as incineration. If
sludge were incinerated by a POTW, for example, this would result in different exposure levels
(and a different, larger exposed population).

Locating the receiving stream reach. In the same method as for TRI reporting facilities,
POTWs are assumed to discharge to the nearest stream reach. However, some POTW-specific
information from EPA data sources was used where it was available.

Off-site Transfers

This category includes any transfers to waste brokers, non-POTW treatment facilities or
recycling facilities, and includes such offsite activities as storage, recycling and recovery,
treatment, incineration, underground injection, landfill, and land treatment (i.e., those TRI
media codes beginning with 'M'). TRI reporters are required to supply the name and address of
the facility that receives wastes for storage or disposal. From these data, EPA determines
whether wastes are sent to a hazardous or nonhazardous waste management facility. As with
underground injection wells, transfers to RCRA hazardous waste facilities are not modeled. If
chemicals are placed in such regulated units, it is assumed that releases to groundwater are
negligible.

The determination of locational data for off-site facilities is conducted in the same manner as
for POTWs.

The RSEI methodology then requires information on the treatment and disposal technologies
used by the facility. If the treatment method is incineration, then destruction and removal
efficiencies (DREs) are applied to the transfer amount, and the releases are modeled using
ISCLT, as described above in the discussion of stack and fugitive air releases.

CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

For off-site landfills, two major exposure pathways are considered: groundwater and
volatilization. These pathways are currently not modeled; however, users can examine pounds-
and hazard-based perspectives for these pathways.

RSEI Results

Because of the multi-functional nature of the model, a variety of results can be created. All
RSEI results start with an Indicator Element, which is a unique combination of chemical,
facility, exposure pathway, and year. Some Indicator Elements may be associated with certain
release and exposure pathways (e.g., direct water releases may be associated with exposure
from drinking water intakes, as well as fish ingestion from recreational fishing and from
subsistence fishing). Each Indicator Element has a set of associated results:

Risk-related results

Surrogate Dose x Toxicity Weight x
Population

Hazard-based results

Pounds x Toxicity Weight

Pounds-based results

TRI Pounds released

Risk-related results. The toxicity, surrogate dose, and population components are multiplied
to obtain a risk score for the Indicator Element. The surrogate dose is determined through
pathway-specific modeling of the fate and transport of the chemical through the environment,
combined with subpopulation-specific exposure factors. The score is a unitless measure that is
not independently meaningful, but is a risk-related estimate that can be compared to other
estimates calculated using the same methods. If the Indicator Element cannot be modeled,
because of the lack of data needed for modeling or because the exposure pathway is not
currently modeled, then the risk-related score is zero. The model calculates risk-related results
for the entire population and also for the following subpopulations: children under 10, children
aged 10 to 17, males aged 18 to 44, females aged 18 to 44, and adults aged 65 and over. In
addition the model also calculates 'Modeled Pounds,' which is simply the number of pounds
that can be modeled for risk-related scores. Modeled pounds are the pounds to which fate and
transport modeling and exposure assumptions have been applied.

Hazard-based results. Each Indicator Element is also associated with a hazard-based result,
calculated by multiplying the pounds released by the chemical-specific toxicity weight for the
exposure route (oral or inhalation) associated with the release. For these results, no exposure
modeling or population estimates are involved. If there is no toxicity weight available for the
chemical, then the hazard score is zero.

The model also calculates 'Modeled Hazard,' which is the chemical-specific toxicity weights
multiplied by the Modeled Pounds (as described above), and 'Modeled Hazard * Pop,' which
multiplies modeled hazard by the exposed population, but without the fate and transport
modeling that would be found in risk-related results.

Pounds-based results. These results include only the pounds of releases reported to TRI, and
are available for all Indicator Elements. The model also provides TRI pounds with toxicity

Version 2.3.1

-------
CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

weights, which just sums the pounds for the chemicals that have toxicity weights in the RSEI
model.

Once results are calculated for each Indicator Element, they can be combined in many different
ways. All of the results are additive, so a result for a specific set of variables is calculated by
summing all the relevant individual Indicator Element results, as follows:

where:

R =	RSEI result, and

lg	_	chemical-facility-pathway-specific

c f p	Indicator Element result.

This method is very flexible, allowing for countless variation in the creation of results. For
example, results can be calculated for various subsets of variables (e.g., chemical, facility,
exposure pathway) and compared to each other to assess the relative contribution of each subset
to the total potential impact. Or, results for the same subset of variables for different years can
be calculated, to assess the general trend in pounds-based, hazard-based, or risk-related impacts
over time.

It must be reiterated that while changes in results over the years would imply that there have
been changes in hazard- or risk-related environmental impacts, the actual magnitude of any
specific change or the reason for the change may not be obvious. Although the value itself may
be useful in identifying facilities or chemicals with the highest potential for hazard or risk, the
weight does not represent a quantitative estimate or provide an exact indication of the
magnitude of individual hazard or risk associated with that facility or chemical.

Analyses That Can be Performed Using the RSEI Model

Users of the model can perform a variety of screening-level analyses, usually in a matter of
minutes. Previously, such activities would have taken days, weeks, or even months to organize
the relevant information, evaluate that information, and perform the complex and sophisticated
analyses that are necessary to provide a risk-related perspective. Results can be used for
screening-level ranking and prioritization for strategic planning purposes, risk-related targeting,
and trends analyses. Considerable resources can be saved by conducting preliminary analyses
with the model to identify risk-related situations of high potential concern that warrant further
evaluation.

As noted above, users can evaluate releases using a number of variables, such as chemical,
medium, geographic area or industry. For instance, the following types of questions can be
investigated:

•	How do industry sectors compare to one another from a risk-related perspective?

•	What is the relative contribution of chemicals within a given industry sector?

•	What release pathway for a particular chemical poses the greatest risk-related impacts?

Periodic updates and troubleshooting information are also available for users.

Important Caveats Regarding the RSEI Chronic Human Health
Model

The RSEI model is a screening tool that provides a risk-related perspective in assessing the
relative impacts of releases of toxic chemicals. Risk-related results are available for releases
and transfers to air and water, and pounds- and hazard-based results are available for all media.
RSEI combines estimates of toxicity, exposure level, and the exposed population to provide
risk-related comparisons. It does not provide a detailed or quantitative assessment of risk, and
is not designed as a substitute for more comprehensive, site-specific risk assessments. There are
a number of important considerations associated with each component of the model, as
described in the following sections.

Release Component

The following caveat should be considered regarding the release component of the model:

•	RSEI uses facility-reported TRI data which is known to contain some reporting errors. Since
facility management must certify reports to be accurate, the TRI program does not change any
reported data until the reporting facility submits an official correction. Therefore, there are
some releases in the TRI data that are thought to be erroneous but are still included because
facilities have not submitted corrected reporting forms by the time of the annual public data
release that RSEI uses. Some of these releases are associated with large risk-related impacts.
One erroneous release warrants special note: a 2002 fugitive air release of 184,770 pounds of
nickel in Johnstown, PA probably overstates the release amount and may be assigned to the
wrong media.

Toxicity Component

The following caveats should be considered regarding the toxicity component of the model:

•	Toxicity weights are not designed to (and may not) correlate with statutory criteria used for
listing and delisting chemicals in TRI. RSEI risk-related model results account for estimated
exposure and may not correlate with listing/de-listing decisions.

•	RSEI only addresses chronic human toxicity (cancer and noncancer effects, such as
developmental toxicity, reproductive toxicity, neurotoxicity, etc.) associated with long-term
exposure and does not address concerns for either acute human toxicity or environmental
toxicity.

Version 2.3.1
May 2012

18

1996-2010 TRI Data


-------
CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

•	Toxicity weights are based upon the single, most sensitive chronic human health endpoint for
inhalation or oral exposure pathways, and do not reflect severity of effects or multiple health
effects.

•	Estimated Reference Doses and Reference Concentrations for noncancer effects incorporate
uncertainty factors which are reflected in toxicity weights that are based upon these values.

•	Toxicity weights for chemicals that are reported to TRI as groups are based on the toxicity for
the most toxic member of the group. One exception to this is polycyclic aromatic compounds
(PACs), the toxicity for which is assumed to be 18% of the toxicity for benzo(a)pyrene, its
most toxic member. This is based on speciation information and follows the method used by
EPA's National-Scale Air Toxics Assessment (NATA) evaluation for polycyclic organic
matter.

•	Several significant assumptions are made regarding metals and metal compounds, because
important data regarding these chemicals are not subject to TRI reporting. Metals and metal
compounds are assumed to have the same toxicity weight, although the chronic toxicity of
some metal compounds may be higher. Metals and metal compounds are assumed to be
released in the valence (or oxidation state) associated with the highest chronic toxicity. The
only exception is chromium and chromium compounds, for which it is assumed that facilities
may release some combination of hexavalent chromium and trivalent chromium. SIC-code
specific estimates from the 2002 National Emissions Inventory are used to estimate the fraction
of each type (available from http://www.epa.gov/ttn/chief/net/2002inventory.html). As trivalent
chromium has a very low toxicity, only the hexavalent fraction is modeled, using a toxicity
weight specifically for that valence state.

•	While the physical form of released metals or metal compounds can affect toxicity, a
reasonable assumption is made regarding the likely form of most releases (e.g., the non-cancer
toxicity weight for chromic acid mists and dissolved hexavalent chromium aerosols is much
higher than for hexavalent chromium particulates, but releases of these chemicals as acid
aerosols are not expected to be typical so the toxicity weight for cancer based on the inhalation
of particulates is used). Analysts need to consider these assumptions, and whether the gathering
of additional data is warranted, when examining model results for metals and metal
compounds.

Exposure Component

The following caveats should be considered regarding the exposure component of the model:

•	Like other exposure models, RSEI estimates exposure levels. It does not yield actual
exposures. The model provides estimated air concentrations in each grid cell.

•	The model uses some generic assumptions, e.g., default median stack heights, diameters, and
exit gas velocities related to 2- or 3-digit Standard Industrial Classification (SIC) codes, or a
nationwide median, where facility-specific median stack height, diameter, and exit gas velocity
data are unavailable. For large facilities with multiple stacks, the median height for all stacks is
used as the stack height for the entire facility.

Version 2.3.1
May 2012

19

1996-2010 TRI Data


-------
CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

•	In the current version of the model, only air and direct surface water exposures are fully
modeled.

•	The model does not account for population activity patterns.

•	The model has greater uncertainty when examining disaggregated results at the local or
facility level. The model does not account for indirect exposure, air deposition of pollutants to
other media, or absorption of pollutants through the skin.

Population Component

The following caveats should be considered regarding the population component of the model.

•	Population values for non-decennial years are estimated based on linear interpolations at the
block level between the 1990 and 2000 U.S. Census datasets, between the 2000 and 2010 U.S.
Census datasets, and on extrapolations back to 1988.

•	Drinking water populations are estimated by using the total drinking water populations
associated with individual downstream drinking water intakes. Estimated populations for the
fish ingestion pathway are based upon U.S. Fish and Wildlife Service surveys.

•	Because RSEI results reflect changing population size at the local level, a facility's relative
contribution could increase or decrease even without changes in its releases over time. While
the model is designed to reflect the overall risk-related impacts on the local population, such
population changes should be considered when examining a facility's environmental
management practices.

Strengths and Limitations of the Chronic Human Health Model

Strengths

The following are strengths of the model:

•	The model provides important hazard-based and risk-related perspectives regarding the
impacts of TRI releases on chronic human health.

•	The model quickly organizes and evaluates complex data. For example, the air exposure
model is combined with U.S. Census data to directly estimate the size of exposed populations
and subpopulations and the magnitude of their exposure, rather than assuming that all
individuals surrounding a facility are equally exposed.

•	The model allows for greatly increased speed in performing screening analyses, thereby
conserving resources for conducting more precise, site-specific risk evaluations. In addition, its
use as a priority-setting tool allows resources to be focused in areas that will provide the
greatest potential risk reduction.

•	The model can perform single- and multi-media analyses.

CHAPTER 1: Welcome to EPA's Risk-Screening Environmental Indicators Model

•	Custom-designed selections can be based upon a wide range of variables.

•	This adaptable method can model any chemical if toxicity characteristics, appropriate
physicochemical properties, release levels and release location are known or can be estimated.

•	The model considers both cancer and non-cancer chronic human health endpoints.

•	The RSEI method has been subject to repeated expert peer review.

•	The model's methodology and assumptions are transparent. Complete and detailed
documentation of the RSEI model is available.

Limitations

The following are limitations of the model:

•	RSEI results do not provide users with quantitative risk estimates (e.g., excess cases of
cancer).

•	RSEI results do not evaluate individual risk.

•	The model does not account for all sources of TRI chemicals; it only accounts for those
sources that are required to report to TRI. It also does not provide scores for all TRI chemicals,
although chemicals without toxicity weights account for a very small percentage of total
releases and of total risk-related impacts.

•	TRI does not account for all toxic chemicals.

•	The model assumes that air concentrations of TRI chemicals are the same for indoor and
outdoor exposures, and that populations are continuously exposed.

•	Dermal and food ingestion pathways (other than fish consumption), and some other indirect
exposure pathways are not evaluated.

•	Acute health effects associated with short-term, periodic exposures to higher levels of these
same chemicals are not addressed.

•	Ecological effects are not addressed.

CHAPTER 2: RSEI Installation Instructions

CHAPTER 2

RSEI Installation Instructions

System Requirements

To install and run the RSEI model requires approximately 2 gigabytes of free hard disk space.
At least 512 megabytes of RAM is recommended. Users must also have Internet Explorer
Versions 3.0 or later installed on their computer to use the RSEI Help feature. Administration
rights are required for correct installation.

It is important to remove any previous versions of the model from your hard drive before you
install this version. Instructions on uninstalling the program are in the Uninstalling RSEI
section below.

These instructions assume you are using Windows 2000, XP, Vista, or 7. This version of the
model will not work on earlier operating systems, such as Windows 3.1. To install the program,
you must have administrator privileges. If you do not have administrator privileges, contact
your computer support personnel.

Early versions of the RSEI model could be run from a CD without an installation on the user's
hard drive. Beginning with Version 2.1, extensive data enhancements have increased the size of
the databases so that running from a CD is no longer possible, and all users must perform the
full hard drive installation. For Version 2.3.1, the installation program only contains data
starting with Reporting Year 1996. Previous years are available for interested users. The
installation program can be downloaded from the RSEI website at www.epa.gov/oppt/rsei. In
addition, the RSEI Census tables are no longer distributed with the model, but can be
downloaded in MS Access format from the RSEI website.

Installing RSEI Using the Downloadable Installation Package

1.	Download the RSEI Version 2.3.1 Installer from http://www.epa.gov/oppt/rsei/pubs/get_rsei.
html.

2.	Double-click on the file (rsei_version_2.3. l_installationfile.exe). This will begin the RSEI
installation. Follow the prompts. The RSEI model will install first, and then the database
driver (Borland's Database Engine, or BDE). You may get an error during the BDE
installation that says there is not enough disk space- this is due to an underestimation of disk
space and does not indicate a problem. Click to continue the installation and it will finish
normally. Depending on the speed of your computer, installation may take several minutes.

Note to users of previous RSEI versions: There is no longer a user directory at C:\Program
Files\RSEI\user. Instead, RSEI stores your tables and queries in a folder called 'RSEI Results'
which is installed under your Windows 'Users' directory, for instance, at C:
\Users\Public\Documents\RSEI Results. Windows configurations may vary, so if you cannot
find the folder there, a hard drive search for 'RSEI Results' will identify the location.

CHAPTER 2: RSEI Installation Instructions

Launching RSEI

When the installation is complete, the install wizard will ask if you want to launch the program.
Click Yes and the RSEI interface will launch.

A good introduction to the many functions in RSEI is the set of three RSEI Tutorials, which
can be found in Chapter 4, or by clicking on the Tutorials button on the first screen of the
model. Once you are comfortable with the basic functions of the model, you can use RSEI to
customize your data output using maps, crosstab tables, sorted tables, filters, and graphs. You
can look at national-level results or the results for a single facility or chemical. Extensive help
is available by clicking the Help button at any point in the model, or in Chapters 5 through 9.

Note that the way the RSEI model appears on your screen will depend on your Windows
settings, including your screen resolution. If some of the displays appear truncated, click on the
Windows Start button, then 'Settings,' then 'Control Panel,' then 'Display,' then 'Settings.' In
the right-hand side of the screen, slide the levers under 'Display area' to the right one or two
notches.

Uninstalling RSEI

RSEI comes with its own Uninstall program that removes the entire program, ancillary files (*.
dll's), and accompanying databases. Click on All Programs->RSEI->Uninstall RSEI and follow
the prompts.

However, the RSEI uninstall will not remove the 'RSEI Results' directory (so that any tables
you have created will not be automatically lost) and the Borland Database Engine with its
associated RSEI settings. You can delete these manually if desired. The 'RSEI
Results'directory is installed in your Windows Users directory (such as C:
\Users\Public\Documents\RSEI Results), or search your hard drive for 'RSEI Results'. The
Borland Database Engine is installed in C:\Program Files\Common Files\Borland Shared, or
you can search your hard drive for the file 'bdeadmin.exe'.

CHAPTER 3: Highlights of RSEI Version 2

CHAPTER 3

Highlights of RSEI Version 2

Version 2 of the RSEI model is a powerful and flexible tool. It allows for many different kinds
of analyses and many ways to customize your results.

Detailed Data

RSEI contains detailed data sets, several of which have been created or quality-assured
specifically for the model. Population data are taken from the two most recent decennial
Censuses at the block level, and translated onto the model grid geographically for greater
accuracy. Off-site facilities have been assigned to their actual locations where possible, and
locations for TRI reporting facilities are taken from EPA's centralized Locational Reference
Tables (LRT). Extensive physicochemical and toxicity data for reported chemicals have been
collected and frequently updated, and detailed (age- and sex-specific, where possible) exposure
factors are used.

Extended Air Modeling

RSEI's air modeling methodology has been revised to more accurately represent concentrations
very close to the facility. In addition, previous versions only modeled concentrations out to 10
km from the facility; the current version models out to 50 km to better reflect the extended
plumes associated with very tall stacks.

Flexible Query Options

Selections can be performed based on any variables included in the model. Boolean-type logic
allows you to exclude and include different sets in the same selection. The query builder is
powerful and flexible, now allowing for any conceivable combination of criteria.

Custom and Preformatted Display Options

The Crosstab tables option allows you to tabulate your selection using any model variables you
choose, and includes sophisticated options like filters, sorted tables, and graphs, and the ability
to collapse and expand rows and columns, and switch row and column variables. You can
create multiple crosstab tables based on the same selection and save and reload different tables.
For quick results, the model provides preformatted displays like a list of facilities and releases
in your selection, time trend graphs, ranked tables, and annual maps.

Enhanced Export Options

You can export tables and lists to many different formats, including Microsoft Excel, Lotus 1-
2-3, and dBase files.

CHAPTER 4: Quick Start Tutorials

CHAPTER 4
Quick Start Tutorials

RSEI tutorials are designed to give you a quick introduction to how the model works, and how
to quickly find basic information that most users are interested in. There are three tutorials
currently available in this chapter to help acquaint you with various aspects of the model.

Remember that while you are working in the RSEI model, you can always refer to Help for
information on model features.

Tutorial 1

An important use of the RSEI model is to identify areas that have potentially high risk-related
impacts. This exercise will walk you through several different ways of doing this. First, you
will perform a national-level selection for the year 2009. You will look at the results by media
and state, and examine the data using several different preformatted functions included in the
RSEI model.

Step 1.1 Perform a National-Level Selection

The first step in any analysis using the RSEI model is to determine the set of elements you wish
to select. This is done by performing a selection. Open up the model to display the RSEI
Welcome screen. Click on the Select button at the top left of the menu panel. This brings up
the Select elements... screen. Here, you can select elements based on any variables included in
the model, including chemical characteristics, geographic location of the facility, year, and
many more. You do this by creating a set of selection statements. For this exercise, we will
create a very simple selection statement.

An element is the hni Icli nu Mock of I lie RSIII model, and is generated lor
each exposure pathway for each chemical release I'or instance, a release
of the chemical benzene to air\ia a stack from the' AlK" I 'acilitx in
ll>iw is an "Indicator l-lement "

Note that if you have done any selections since installing the RSEI model, your last selection
statement will appear on the Select elements... screen. Click on the Clear button to remove
previous selection statements. You will see a line of text on the screen, 'Choose records where
all of the following apply'. This is a bracket statement that tells the model what to do with the
information that comes next. You can change the bracket statement from 'all' to 'any', 'none',
or 'not all' by clicking on the 'all' and selecting an option from the drop down menu. But for
now let it remain 'all'. Click on the circle to the left of the text, and select 'Add condition'.

CHAPTER 4: Quick Start Tutorials

Selection statements tell the model what releases you wish to select.
Selection statements are comprised of bracket statements that tell the
model to select records where all, any, none, or not all of the conditions
apply and condition statements, that specify exactly what your conditions
are.

The condition statement contains the criteria you use to select your releases.

You will see the following text line:

1. Chemical Flags. Year Chemical Added is equal to	

Click on the first part of the text line, and a drop-down menu will appear. This menu contains
all of the variables contained in the model that you can use in your selection statements. They
are grouped according to the type of variable. Click on the group 'Submission'. To the right
you will see another menu with all of the variables in this group. Click on 'Year'.

The text line will change to 1. Submission. Year is equal to	. Click on the blank at the end of

the line, and select '2009' from the list.

Select Elements... Screen

This will now select all TRI-reported releases that occurred in 2009. Click on the Submit
button at the top of the Select elements... screen to submit the selection. The model may take a
few minutes to complete the task.

If you accidentally submit an incomplete or inaccurate selection
statement, you cannot stop the submission or go back to the statement
until the model has processed your submission completely. Once the
model is done, click on the Select button again to reopen the Select
Elements... screen, correct the selection statement, and resubmit it.

When the model is done with the selection, the Select elements... screen will disappear. The
number of facilities, chemical releases, and elements that are selected in your set will be
displayed in the top right corner of the screen.

Now that you have your selected set of scores, you can analyze them in different ways. To get a
quick summary of the differences in risk-related impacts between states, click on Thematic
Maps at the top of the screen.

The model will display a U.S. map, where variations in color represent differing levels in
impacts. Your map may show Alaska and Hawaii; if you want to see only the continental U.S.,
click and drag the map to the left until Hawaii and Alaska no longer show. The legend at the
left side of the screen shows the values that correspond to the colors on the map. The default
data year is set to 2010, so you must select '2009' from the drop-down menu next to Select
Year in order to see any data on the map. Also, make sure that the Theme box shows 'Score'.
If you want to increase the size of the map, draw the outline of a box around the area you want
to enlarge with the cursor while holding down the right mouse button. To outline the states,
click on the Show feature outlines box.

Custom Tables Screen

In this screen you can create and customize crosstab tables, based on any combination of
variables you choose. To create a new crosstab table, click on the New Table button. The
Select Dimensions screen will appear. This screen lists all the variables included in the RSEI
model. The variables are listed in the form 'Data table.variable name', where the data table is
similar to the variable group used in the Select elements... screen. A complete listing of all
variables is provided in Chapter 5.

Select the rows and columns that you want to appear in the crosstab table. You may select any
number of variables, but selecting more than two or three will greatly increase the time needed
to generate the table and the complexity of reading the table. Note that the various RSEI
outputs (e.g. pounds, hazard score, risk-related score, etc.) will be the contents of the cells of
the crosstab. You do not need to specify RSEI outputs at this point.

Select Dimensions Dialog

We want to look at state-level results, so select 'Facility.State'. It is often informative to break
down results by media, in order to assess what exposure routes are associated with the highest
risk-related impacts. So select 'Release.Media Text', which will provide the text description of
the medium into which each chemical is released. In the box to the right of 'Name' at the
bottom of the screen, type in a name for this table you are creating, such as '2009 State by
Media'. All of the tables you create in the RSEI model are saved on your hard drive for later
use. Hit Run! and the model will create your crosstab table. It may take a few minutes to
generate. When the model is finished, you will see the new crosstab table, as shown below.

Crosstab Table, State by Media

This table shows, for each state, the risk-related score for each medium. This is the top number,
in black, in each cell. For cells with non-zero values, the number in red beneath the score is the
cell's percentage of the total score of all the cells in the table (the total can be found in the
lower right corner). The values below the top number in black in each cell can be changed by
clicking Options, then Cell Display. The default (the value shown in red in the table) is the
'Total Pet'. To turn it off, simply click on the text so that the check mark is removed.

The box at the top of the screen, where 'Risk-related Results' is displayed, controls what
numbers are shown in black in the cells of the table. Explanations for each type of number can
be found in the Options section at the end of Chapter 9. 'Risk-related Results' refers to the full
model score: the risk-related, unitless number that takes into account the chemical release, its
toxicity, environmental fate and transport, exposure assumptions, and the number of exposed
people.

Note that there are many media that have only zeros for entries. To get rid of all zero-only
entries, click on the minus sign to the left of the row header 'Media Text'. This collapses the
rows, and the minus sign is replaced with a plus sign. Click on the plus sign to expand the row
again; now, however, the zero-only rows will not be displayed.

Any time you change the 'Value Selected', you should collapse and
expand the rows and columns to refresh the table. Otherwi se, rows or
columns that were not shown originally because all of the values were
zero may not show when the summary is changed, even if in the new
summary their values are non-zero.

Because the crosstab table displays so much information at one time, sometimes it is useful to
quickly summarize the information in the table. The Sorted Table function works from the

Sorted Table, State by Media

This table shows each state-medium combination, listed in descending order of risk-related
impact. The sixth column, 'Cumulative Value', shows the total value of the score for each entry
and all of those above it. The 'Cumulative Percent' column functions in a similar way. You can
see that fugitive air releases in Missouri account for approximately 14 percent of the total risk-
related impact in the country for 2009.

To do a more direct comparison of states, go back to the custom table by clicking on the Table
button. Collapse the rows by clicking on the minus sign to the left of the 'Media Text' row
header. Then click on the Sorted Table button again. This time, instead of showing state-media
combinations, the table only shows the state rankings. You can see that Texas is the state with
the highest calculated risk-related impact, accounting for almost 15 percent of the nation's total
in 2009.

Custom Graph, Total for Top 5 States by Risk-Related Results

This tutorial began with a national-level analysis, then narrowed in on the five states with the
highest risk-related results. The next tutorial will narrow the analysis even further, looking
more closely at one state.

Tutorial 2

Now you can take a closer look at an individual state, and what comprises its score. Let's look
at Texas, the highest ranking state in risk-related impacts. We know from looking at the first
sorted table in Tutorial 1 that fugitive air releases are responsible for the highest risk-related
impacts in Texas. But what chemicals are mostly responsible for these impacts?

Step 2.1 Perform a State-Level Selection for Texas

First, limit your selected set to releases from facilities located in Texas by performing a new
selection. Click on the Select button. The screen should display your last selection, which was
'Submission.Year is equal to 2009'. To add another condition statement, click on the ' V to the
left of "Submission", then click Add Condition. A new line of text will appear. Click on the
line, 'Chemical Flags.Year Chemical Added', then click on 'Facility Location', then 'State'. In
the blank at the end of the line, type in the abbreviation for Texas, 'TX' . Remember that fields
for which you must type the selection criteria are case sensitive. Click somewhere else in the

window aside from the box you just typed in, to enter your change (all of the text in the line
will then turn blue). Your selection statement should look like the one below. Click Submit.
The model may take a few minutes to complete the task.

Select elements..,

~ pen | Save | Clear | Submit | Special | Cancel |

Choose records where aN of the following apply
1. Submission/Year is equal to 2009
'2.) Facililti1 Location.State is equal to TX

Enter Description (optional)

The Select Elements... Screen

When the model is done with the selection, the Select elements... screen will disappear. The
number of facilities, chemical releases, and elements that are selected in your set will be
displayed in the top right corner of the screen.

Step 2.2 Results for Texas, Chemical by Media

Click on the Custom Tables button at the end of the second row of menu buttons at the top of
the screen. Now we will look at what chemicals are being released by facilities in Texas, and
the media into which they are released. Click New Table, and select 'Chemical.Chemical', and
'Release.Media Text'. The selections for your previous table will still be displayed, so make
sure to deselect them. Similarly, the name of the previous table will be displayed in the 'Name'
box at the bottom of the screen. Delete that name, and type in a new name for this table, for
instance, 'Texas 2009 Chemical by Media'. Hit Run! and the model will create your new table.
The table may take a few minutes to generate; when it does you will see the following screen (if
the graph is still displaying, click on the Table button):

Sorted Table, Chemical by Media for Texas, 2009

You can see from this table that over 24 percent of the calculated score in Texas for 2009 is due
to fugitive air releases of Propyleneimine. To look at the rankings only by chemical, go back to
the Table screen and collapse the rows by clicking on the minus sign to the left of 'Media
Text', and then click again on the Sorted Table button, as we did in Tutorial 1. The table is
shown below. You can see that, when releases to all media are considered, Propyleneimine has
the highest risk-related results, and Chromium and chromium compounds has the second-
ranked highest risk-related results.

Sorted Table, Chemical Only for Texas, 2009

While in the Sorted Table, you can change the selection in the 'Value Selected' drop-down
box, and see the rankings of chemicals by TRI Pounds, Hazard, or other model results. You
will notice that the rankings can change quite dramatically. The change can be for a number of
reasons. One very common reason is illustrated by the releases for Zinc and zinc compounds,
which ranks second in TRI Pounds, but 88th in the Risk-related Results perspective. For this
chemical, the higher toxicity weight (of the two inhalation and oral weights) is 100, compared
to that for the highest-ranking chemical by risk-related results (Chromium and chromium
compounds), which is 43 billion. Another thing to keep in mind is that approximately 37.9
million pounds (99 percent of the 38 million total pounds) of the Zinc and zinc compounds
releases are transferred to off-site recycling or disposal facilities or landfilled. The RSEI model
does not consider the risk (if any) that may result from these pathways, so these releases are not
reflected in the ranking by Risk-related Results.

When analyzing RSEI results, another factor to keep in mind is that while RSEI uses the best
available data, inevitably some data sets will contain errors, and some assumptions are made in
the absence of sufficient data. For instance, in this selection, the second-highest chemical-
medium combination by risk-related impact is fugitive air releases of Chromium and chromium
compounds. This could simply reflect releases that are resulting in high risk-related impact.
However, the results could also be affected by some of the data used or the assumptions that are

Version 2.3.1

1996-2010 TRI Data


-------
CHAPTER 4: Quick Start Tutorials

made in modeling the air pathway, such as average weather patterns, population placement, etc.
The 7th-highest combination is POTW releases of o-Toluidene, which may be affected by the
assumptions used in modeling the water pathway, such as the locations of various points used
in the exposure modeling: the facility effluent pipe, drinking water intakes, or the number of
people exposed through drinking water or fishing. RSEI results are screening level only, and
should be followed up with further analysis.

Step 2.3 Time Trend Analysis for High-Ranking Chemicals

You might want to see the trend in the releases of Texas' highest-ranking chemicals over
several years, to see if releases and scores are increasing or decreasing. To do this, begin by
modifying the last selection statement to limit the selected set to releases of these chemicals
only. Click on the Select button to return to the Select elements... screen. The two statements
used in the previous selection will still be showing:

1.	Submission. Year is equal to 2009

2.	Facility Location. State is equal to TX

Click on the circle to left of the first statement, and then click on 'Add Bracket'. The line of
text, 'all of the following apply' will appear. This is a bracket statement telling the model how
to interpret the list of conditions that will follow. We are going to add a list of five chemicals,
and we want releases for any of them to be selected, so click on 'all' and then click on 'any' in
the drop down list. The text line should now say 'any of the following apply'.

You will now add your list of chemicals. Click on the text, 'Chemical Flags. Year Chemical
Added', and then click on 'Chemical Identifiers', then 'Chemical'.'Chemical Identifiers.
Chemical' will show in the text line. Click on the blank at the end of the text line, and a screen
will pop up that lists all of the chemicals included in the RSEI model. Scroll through the list
until you come to the first chemical to select, 'Propyleneimine'. Click on that chemical, and it
will appear in the text line in your selection statement. Click on the '3.1' at the beginning of the
line, and click 'Add Condition'. Repeat these steps to select 'Chromium and chromium
compounds', 'Diaminotoluene (mixed isomers)', ' 1,3-Butadiene', and 'o-Toluidine'.

In order to look at time trends, you need to make another modification to your selection
statement. In the first condition statement, which says 'Submission.Year is equal to 2009'. click
on the circle at the beginning of the line and select, 'Delete current row'. Without any selection
for year, the model will automatically select all years from 1996 through 2010.

Because you are doing a time trend, it is important not to inadvertently introduce other factors
into your analysis. For Reporting Year 1998, TRI added a number of new industries that had
not previously been required to report to TRI. If these facilities are not accounted for in the time
trend analysis, the results for 1998 and after will look much higher than those for previous
years, simply because more facilities are included. If you exclude the new reporters, you will be
working with the same set of facilities for all years, and so will get a more accurate sense of the
trend over time.

To exclude these facilities, create a new bracket statement by clicking on the first empty circle,
and clicking on 'Add Bracket'. In the new line that appears, change the 'all' to 'none'. Click on

Version 2.3.1
May 2012

1996-2010 TRI Data


-------
CHAPTER 4: Quick Start Tutorials

the first part of the new condition statement, and select 'Facility Industry', then 'SIC Code 1'.
Click on the blank space at the end of the line, and in the window that appears, select the first
code, 1021 [Copper Ores], Then add a new condition by clicking on the '4.1' at the beginning
of the line, and click on 'Add Condition'. Then repeat the same steps, but instead selecting
1031 in the SIC code window. Do this for each of the following SIC codes: 1041, 1044, 1061,
1099, 1221, 1222, 1231,4911,4931,4939, 4953, 5169, 5171, and 7389. In order to view the
entire selection statement, you will need to maximize the 'Select elements...' window. Your
selection statement should look like the one below.

o Choose records where all of the following apply

1.	Facilitv.Location.State is equal to TX

2.	any of the following apply

2.1	Chemical Identifiers.Chemical is equal to Propyleneimine

2.2	Chemical Identifiers.Chemical is equal to Chromium and chromium
compounds

2.3	Chemical Identifiers.Chemical is equal to Diaminotoluene (mixed isomers)

2.4	Chemical Identifiers.Chemical is equal to 1.3-Butadiene

2.5	Chemical Identifiers.Chemical is equal to o-Toluidine

3.	none of the following apply

3.1	Facility Industry.SIC Code 1 is equal to 1021

3.2	Facility Industry.SIC Code 1 is equal to 1031

3.3	Facility Industry.SIC Code 1 is equal to 1041

3.4	Facility Industry.SIC Code 1 is equal to 1044

3.5	Facility Industry.SIC Code 1 is equal to 1061

3.6	Facility Industry.SIC Code 1 is equal to 1099

3.7	Facility Industry.SIC Code 1 is equal to 1221

3.8	Facility Industry.SIC Code 1 is equal to 1222

3.9	Facility Industry.SIC Code 1 is equal to 1231

3.10	Facility Industry.SIC Code 1 is equal to 4911

3.11	Facility Industry.SIC Code 1 is equal to 4931

3.12	Facility Industry.SIC Code 1 is equal to 4939

3.13	Facility Industry.SIC Code 1 is equal to 4953

3.14	Facility Industry.SIC Code 1 is equal to 5169

3.15	Facility Industry.SIC Code 1 is equal to 5171

3.16	Facility Industry.SIC Code 1 is equal to 7389

Because this is an intricate and useful query, it is a good idea to save it for later use. Type in a
description, such as Texas, 1996-2010 top 5 chemicals excluding new reporters', in the white
box at the bottom of the window. This is a text description that will be saved with your query.
Click on Save at the top of the window, and enter a shorter name for your query, such as Texas
top 5 96-10 exc new'. The model will automatically add a '.qry' extension to your selection
name. In the future you can load this query and either resubmit it, or use it as the basis for
building new selection statements.

Click Submit, and the model will perform the selection. The model may take a few minutes to
complete the task. When the model is done with the selection, the Select elements... screen will

disappear. The number of facilities, chemical releases, and elements that are selected in your set
will be displayed in the top right corner of the screen.

One of the quickest ways to look at a trend over time is to use the preformatted graphs
provided. Click on the Summary button in the second row of menu buttons, then Chemical
Rank. The chemical rank tables are for single years; 2010 shows by default, but you can select
a new year from the drop-down menu. Notice here that in 2010, Propyleneimine has the lowest
rank of the five, while it had the highest rank in 2009.

You can also click on the Total by Year button under the Summary menu. This graph adds
together all of the pounds and the scores of all of the chemical releases in the selected set and
presents them separately for each year in the set. In this case, it would be all of the chemical
releases of Propyleneimine, Chromium and chromium compounds, Diamonotoluene (mixed
isomers), 1,3-Butadiene, and o-Toluidine in Texas, excluding the new reporters. The graph is
shown below. Pounds (as reported in TRI) are shown in green, and correspond to the axis on
the right side of the graph; the total score is shown in red and corresponds to the axis on the left
side of the graph. You can see that both pounds and score have fluctuated over time. The score
was at its highest point in 2001, and is substantially lower in 2010.

Custom Graph for Selected Chemicals in Texas, 1996-2010

This graph clearly shows that the increase in 2001 is being driven by Chromium and chromium
compounds. If you click on Sorted Table, you can see that fugitive air releases of Chromium
and chromium compounds account for almost five percent of the total risk-related results in this
set.

You can also export the table, in order to do calculations in a spreadsheet, for example. While
viewing your table, simply click on Export in the top row of menu buttons, and select the type
of file you would like your table to be exported to. Click on the folder icon to the right of the
'Export to File' box at the bottom of the window, and select the directory in which you would
like to store your exported file. The default directory for stored files is the 'RSEI Results'
folder under your Windows Users directory, but you can export the file anywhere. Enter a name
at the bottom of the screen and click Save. In the Setup of the data export screen, click OK,
and the model will export your table. You can then open up the file in whatever program you
selected. Your exported table will contain all of the results fields (TRI Pounds, Hazard, Risk-
related Results, etc.) in one table.

Step 2.4 Further Analyses

If you wish to determine what facilities had fugitive air releases of Chromium and chromium
compounds in 2001, you could go back to the Select elements... screen and add a condition
statement by clicking on the first empty circle. Modify the condition to read, 'Release.Media
Code equal to 1'. This will change your selection to only fugitive (media=l) air releases. You
could also add another first statement to be 'Submission.Year is equal to 2001', and delete the
other chemical selection statements by clicking on the row number and selecting 'Delete
Current Row.' Then you could create a new Custom Table showing 'Facility Name' by 'Year'.
This would show you which facilities released Chromium and chromium compounds in 2001.

Tutorial 3

This tutorial will explain some of the facility-specific features in the RSEI model.

Step 3.1 Select a Group of Facilities

In this step, you will make a selection based on the county where the releasing facilities are
located.

Click on the Select button at the top left of the menu panel. This brings up the Select
elements... screen, where you can specify what TRI releases you want to select. Note that if you
have performed any selections since installing the RSEI model, your last selection statement
will appear on the Select elements... screen. To remove it, simply click on the Clear button.
You will see a line of text on the screen, 'Choose records where all of the following apply'.

This is a bracket statement that tells the model what to do with the information that comes next.
You can change the bracket statement from 'all' to 'any', 'none', or 'not all'. But for now let it
remain 'all'. Click on the circle to the left of the text, and select 'Add condition'. The condition
statement contains the criteria you use to select your releases.

You will see the following text line:

1. Chemical Flags. Year Chemical Added is equal to	

Click on the first part of the text line, and a drop-down menu will appear. This menu contains
all of the variables contained in the model that you can use in your selections. They are grouped
according to the type of variable. Because we are selecting releases for facilities in a certain
place, click on the variable group 'Facility Location'. To the right you will see another menu
with all of the variables in this group. Click on 'County'.

The text line will change to ' 1. Facility Location.County is equal to	'. Click on the blank at

When the model is done with the selection, the Select elements... screen will disappear. The
number of facilities, chemical releases, and elements that are selected in your set will be
displayed in the top right corner of the screen. These numbers will remain displayed until you
select a new set of scores. If you forget what your selection statement was, click on these
numbers, and a window will appear with your original statement.

Now we can look at all of the facilities whose scores you have just selected. Click on the
Selected Facilities Browser button in the second line of the menu panel. You will see a screen
with three parts. The parts work together to provide detailed information on the facilities you
have selected. The top part of the screen lists all the facilities whose scores have been selected.
The bottom left is a U.S. map you can use to display your selected facilities and other options.
The bottom right of the screen displays information about the current map display and provides
the buttons used to navigate the map and control its functions.

Step 3.2 Getting Information About a Facility

Facility Information, Submissions, Releases and Scores

Double-click on the first facility name in the selected facilities list. You will see two options,
'Submissions' and 'Full Facility Record'. The latter option provides all of the information
included in the model about this facility - its address, stack parameters, public contacts, etc.
Double-click on 'Full Facility Record' or click on the plus sign to the left of the text to see all
of the information. Then click on the minus sign at the far left to collapse it again. Expanding
the 'Submission' option shows each chemical release that this facility has submitted to TRI.
Double-click on a chemical name highlighted in green, then expand the 'Releases' option, and
the model will show you the releases of that chemical - that is, the media that the chemical is
being released to, as well as the total pounds released, and the total score. Double-click on the
name of the media, and then on 'Scores' and the model will show you the score (the Risk-
related Results of the model) for that chemical release to that media. To hide any of these
records, simply click on the small minus sign at the beginning of the row. The list works like a
directory tree that you can expand and collapse to see different levels.

CHAPTER 4: Quick Start Tutorials

Facility Location

You can also see where on the map your facility is located. With the facility name, or any part
of the facility's submission record highlighted, click on the facility location icon in the lower
right portion of your screen. The map will zoom into the state where your facility is located,
and show you its exact location with concentric circles.

Facility Names \izL

Click on the Show/Hide Facility Names icon to display the names of all facilities. If your map
is zoomed out too far, the names will appear printed over each other and will be illegible. This
function is only useful when you are zoomed in to a handful of facilities. To remove the facility
names, simply click on the button again.

Step 3.3 Further Analyses

The steps outlined above should give you a good idea about one particular facility. However,
the model contains much more information that can show you how that facility has been
performing over time, or how it ranks in comparison to all facilities in the country, or facilities
in similar geographic areas, or in similar industries.

To do a time trend analysis to see if a facility's risk-related score is getting better or worse over
time, first do a selection based just on that facility. The easiest way is to simply use the Facility
ID, the first column in the Selected Facilities Browser, then go back to the Select elements...
screen, and create a new selection statement with a condition that says 'Facility Identifier.
Facility ID is equal to X'. where X is the Facility ID from the Selected Facilities Browser (you
can copy the Facility ID from the Selected Facilities Browser by right-clicking on the ID, then
typing Control-C to copy the ID to the Windows clipboard. You can then paste the ID in the
selection statement, or in any other Windows program by typing Control-V). When the model
is done with the selection, you can click on the Summary button in the second line of the menu
panel, and see preformatted graphs that show total score and pounds by year, and total pounds
and total score by media by year.

To see how your facility ranks in relation to other facilities, first select a set that includes your
facility and all of the facilities to which you want to compare it, for instance, all facilities
nationwide in 2005. Your selection statement in the Select elements... screen would say
Submission.Year is equal to 2005. This selects all releases from all facilities in 2005. When the
model is done with your selection, click on the Custom Tables button. Follow the directions
under that heading in Creating a New Table in Chapter 9 to make a crosstab table of your
results. If you make a table using 'Facility Name' and 'SIC code' as row and column variables,
then you can click on the Sorted Table button to see a ranking of all the facilities in order of
highest score (or pounds, depending on what Value you have selected) to lowest score. If you
want to look at the facilities that are in the same industry as your facility, then apply the filter to
'SIC Code 1', and select just your facility's SIC Code. Then click back to the Sorted Table, to
see a ranking of all the facilities just in that SIC code.

Category Data

This data set is a lookup table that lists the codes used to categorize how releases are modeled.
The score category codes resemble the media codes that are reported by TRI facilities, but also
include information on how the model is able to deal with specific kinds of releases.

Category Data

Variable

Census Data

RSEI Census data are contained in three tables, Census 90 (data from the 1990 Census), Census
00 (data from the 2000 Census) and Census 10 (data from the 2010 Census). These three tables
contain the Census data that has been transposed onto the RSEI model grid. See the
Introduction for a description of how Census data are used in the model. Each Census table is
over 600 MB in size. They cannot be exported. 1990 Census data have been provided by
Geolytics, Inc.; Census data were last updated in 2012.

Due to their size, the Census tables are not included in the standard RSEI download. Separate
zip files, each containing one of the three Census tables in MS Access format,are available for
download from the RSEI website. The tables cannot be viewed through the RSEI Data viewer.

CHAPTER 5: Viewing Data

Chemical Data

This data set lists all of the chemical-specific information used by the model. The data can be

grouped into four categories:

•	Chemical identifiers include CAS numbers and chemical names.

•	Chemical toxicity information includes all of the information used to construct toxicity
weights for each chemical. Of the 611 chemicals on the 2010 TRI Reporting list, 430
chemicals have toxicity information included in the model. The sources of these values, in
the order of most to least preferred, are EPA's Integrated Risk Information System (IRIS);
EPA Office of Pesticide Programs' Toxicity Tracking Reports and Pesticide Reregi strati on
Eligibility Documents (OPP); Agency for Toxic Substances and Disease Registry final,
published chronic MRLs (ATSDR); California Environmental Protection Agency's Office of
Environmental Health Hazard Assessment final, published toxicity values (Cal/EPA); EPA's
Provisional Peer Reviewed Toxicity Values (PPRTVs), which include toxicity values
developed by EPA's Office of Research and Development/National Center for Environmental
Assessment/Superfund Health Risk Technical Support Center (STSC); EPA's Health Effects
Assessment Summary Tables (HEAST); and Final Derived/Interim Derived Toxicity Weights
(Derived) estimated by EPA's Office of Pollution Prevention and Toxics. In cases where
none of the above sources had sufficient data, other secondary sources were consulted and
reviewed by EPA experts (Derived). Chemical toxicity data are reviewed and updated on a
continuing basis. See Technical Appendix A for toxicity values.

•	Chemical Properties information includes all of the physicochemical properties used to
model the fate and transport of the chemicals in the environment. Experimental and estimated
data are used, most of it obtained from sources published by Syracuse Research Corporation
(SRC). These data are also reviewed and updated continuously. See Technical Appendix B
for details on each parameter.

•	Chemical Flags are markers that can be used to select chemicals that are designated in
specific ways, usually by EPA. Examples include Hazardous Air Pollutants (HAPs), or
chemicals regulated under the Safe Drinking Water Act (SDWA). The chemical flags were
last comprehensively checked against each relevant list in the summer of 2008.

*Even if a chemical is flagged as an OSHA carcinogen, its toxicity weight for a given exposure pathway
may not be based on its carcinogenic effects. For example, a chemical that causes both carcinogenic and
noncarcinogenic effects when inhaled may have a higher inhalation toxicity weight associated with
noncarcinogenic effects than with its carcinogenic effects. If you wish to view all chemicals that have
inhalation toxicity weights based on cancer health effects, see the Toxicity Class - Inhale field. For a list of
chemicals that have toxicity weights based only on cancer health effects, see the Toxicity Category field.

County Data

This data set is based on U.S. Census data, and was last updated in August 2000. Total county
population is taken directly from U.S. Census bureau estimates (these data are not directly used
in the model). Total fishing population is obtained from state counts of county-specific records
on hunting and fishing licenses, where available. The fishing population is used to model the
ingestion of contaminated fish in one of the two surface water pathways. In the model, the total
fishing population is adjusted for family size (to take into account the family of the licensed
fisher who also eat the caught fish), and 95 percent of the total is considered to be recreational
fishers, and 5 percent are considered to be subsistence fishers; the variable in this data set is the
unadjusted number of licensed fishers only. The fishing population data were collected and
added to the model for the first time in August 2000. See Chapter V of the Methodology

Facility Data

This data set is a combination of TRI Reported data, and derived data used to model emissions

Derived stack parameter data were primarily collected from three national EPA databases (NEI,
AFS and NET). AFS and NET data were last collected in 2001; NEI data was last collected in
2008. Facilities are matched where possible- i.e., facility-specific parameters are used. For
facilities that cannot be matched, median values at the 3-digit SIC code level (constructed using
only AFS and NET data) are used. If that is not possible, in cases where the TRI facility did not
submit a valid SIC code, or there are no facilities for that SIC code in the two EPA databases,
median values for all SIC codes are used. The NEI/AFS/NET data are supplemented by a one-

CHAPTER 5: Viewing Data

time data pull conducted in 1998 from three state databases containing facility-specific data.
The states involved are Wisconsin, New York and California. Only data for facilities that were
not matched through AFS/NET were used from these databases. Starting in Reporting Year
(RY) 1998, electric utilities are required to report to TRI. Because their stack parameters are
generally quite different from other facilities, facility-specific data collected by the Electric
Power Research Institute (EPRI) were used to represent these facilities. In cases where facilities
falling in the electric utility SIC codes could not be matched, the overall median of all coal and
gas electric utilities from EPRI's data set was used. For the complete method used in this
process, see Technical Appendix E.

Most facility locations are obtained from EPA's Locational Reference Tables (LRT). A small
number of facilities did not have coordinates available in the LRT; for these facilities, either
previous RSEI coordinates or zip code centroids were used. For a complete account of this
process, see Technical Appendix D.

The SIC code data are based on the primary and additional five SIC codes reported by facilities
on each Form R. They are described as "Derived" in the the table below because the submitted
data are processed to make them easier to use before including them in the model. Facilities
may submit multiple Form R's, and so may report more than six SIC codes in total, and more
than one primary SIC code. For any facility that has multiple primary SIC codes, RSEI assigns
the most frequently reported. If more than five additional SIC codes are reported, RSEI assigns
the five most frequently reported as SIC Codes 2 through 6. Users can use the other fields to
make selections at a more aggregated level (2 or 3-digit SIC Codes). For details, see Technical
Appendix F. NAICS codes, which facilities are required to report instead of SIC codes
beginning with RY 2006, are handled in the same manner.

MCL (Maximum Contaminant Level)

This data set contains yearly information on Maximum Contaminant Levels (MCLs) that EPA
sets for chemicals to limit the level of contaminants in drinking water from public water
systems. As the MCLs are legally enforceable, the RSEI model assumes that drinking water
from public systems is in compliance with these standards. The first MCLs were instituted in
1976; changes to existing MCLs and new MCLs have been instituted since then, including the
addition of a large number of new MCLs in 1991.

This table lists the value for each MCL for each year of TRI data. For several chemicals for
which MCLs were first instituted in 1976 and then revised in 1991, the original MCL values

CHAPTER 5: Viewing Data

Off-site Data

This data set is derived from TRI reported data. Offsite facilities are any facilities to which a
TRI reporting facility transfers a reportable chemical. The names and addresses of these offsite
facilities are reported by the TRI facilities transferring their chemicals. Because multiple
facilities may transfer chemicals to the same offsite facility, the same offsite facility may be
reported multiple times in slightly different forms. To approximate a set of unique offsite
facilities, a sophisticated program was developed to match slightly different reported entries
that are in reality the same offsite facility. Because latitude and longitude are not reported but
are necessary to model releases, the offsite facilities were geocoded (assigned latitude and
longitude coordinates based on street address) by Thomas Computing Services, a commercial
firm, using standard geocoding software based on U.S. Census Tiger files. Other EPA
databases were also used for matching and locational information. This data set contains the
results of both the matching exercise and the geocoding exercise. For a complete account of the
process, see Technical Appendix D.

WSDB (Water System) Data

This data set contains public water systems, the locations of their drinking water intakes
(although this information is not viewable by the public), and the population served by each
intake. These data are taken from USGS's Public Supply Database and EPA's Safe Drinking
Water Information System (SDWIS). However, this data set only lists the intake location and
the number of people served by each intake, not the location of the served population itself. In
the absence of data on exactly which people are drinking from the intake in question, the model
assumes the closest people to the drinking water intake are using it. This data set was last
updated in 2009.

This data set also contains information on the reach that supplies the drinking water intake. In
the absence of this information, it is assumed that the intake is located on the reach nearest the
reported coordinates for the drinking water intake. If no reach is found within one kilometer of
the reported coordinates, then exposure for that intake is not modeled. The closest reach was

CHAPTER 6
Selecting Releases

Selecting releases (Select button)

The Select button, found at the top of the menu panel, allows you to build selection statements
that pull out specific subsets of data in the model. These subsets can be based on the geographic
locations of facilities, the year of the chemical releases, the kinds of chemicals released, or any
other single variable or combination of variables included in the model. This selection will then
be used as the basic data set for all of the other model functions, like crosstab and sorted tables,
graphs, and maps.

The following sections explain how the Select button can be used to develop new selections,
and save and reopen them. Pressing the Select button brings up the Select elements... screen.

The Select Elements... Screen

Opening Existing Selections

The Open button loads the selection statements for selections that have already been saved.
The default directory for saved selections is in the 'RSEI Results' folder under your Windows
Users directory, although you can store them anywhere. Once opened, you can edit the
selection, or just click Submit to run the selection.

New Selections

Each selection is made up of one or more selection statements, which tells the model what kind
of records you want to pull out of the database. Each record is an element - the building block
of the model that defines a chemical release to a specific exposure pathway. There are two parts
to each selection statement - bracket statements and condition statements. Bracket statements
tell the model how to interpret a list of conditions. Bracket statements always come
immediately before a condition or a list of conditions. When you click on the Select button and

the Select elements... screen opens, the first line of text in the dialog box is a bracket
statement, 'Choose records where all of the following apply.' This bracket statement tells the
model that a list is coming, and to only select those scores to which ALL of the conditions in
the list apply. If you click on all, a drop-down box will appear with the other operators you can
choose: any, none, or not all.

top of the screen to remove all but the very first bracket statement.

Condition statements are the actual criteria you use to select elements. For instance, a condition
could be that the facility releasing the chemical is located in New York, or that the chemical
being released is benzene. Condition statements can pull out any variable that is included in the
model, and select elements that are equal to the criteria you enter, or not equal, less than,
greater than, etc. With the combination of bracket and condition statements, you can construct
very complex selections to pull out only those elements you are interested in.

Once you have completed your selection, you can either submit it (by clicking the Submit
button) or further refine it by adding more conditions and/or selection statements.

To add more conditions within the same bracket statement, click on the ' 1' to the left of your
first condition, then click 'Add condition.' A new text line will appear, which you can change
to reflect your desired criterion. Remember that because you are within the same bracket
statement, the model will evaluate this condition along with the first, according to whatever
bracket operator you selected in the bracket statement. For instance, if you selected 'any' as
your bracket statement operator (in the first text line), your first condition was 'Facility
Location.State is equal to NY' and your second condition was 'Chemical Identifiers.Chemical
is equal to Benzene,' the model will return all releases from facilities in New York (regardless
of the chemical) PLUS all releases of benzene in the U.S. (regardless of the state). If what you
really wanted was all releases of benzene from New York, change the bracket statement
operator in the first text line to 'all'. Then the model will only select those releases that are 1)
from facilities in New York, and also 2) benzene releases.

You can also add additional selection statements. Having more than one selection statement is
useful when you want to use different operators on different sets of criteria. For instance,
consider the example above of benzene releases in New York. Perhaps you would like to look
more closely at benzene releases and chlorine releases in New York. In this case, you cannot
simply add another condition statement for chlorine (with 'all' as the bracket operator), because
the model will then look for releases that are 1) from facilities in New York, 2) benzene
releases, and 3) chlorine releases, which is not logically possible. So here you can use an
additional bracket statement to group together benzene and chlorine, and direct the model to
pick releases that are either one.

Enter Description (optional)

Selection Statement

To select benzene and chlorine releases in New York, keep the first text line as is, so it reads
'Choose records where all of the following apply.' Then click on the circle to the left of the text
line, and choose 'Add Condition.' For the first condition, enter 'Facility Location. State is equal
to NY.' Then click on the ' 1' next to the condition, and click 'Add Bracket.' Change 'all' to
'any'. In line 2.1, which is the first condition of your new selection statement, change the
variable to read, 'Chemical Identifiers.Chemical is equal to Benzene.' Then click on the circled
'2.1', and click 'Add Condition.' A new line 2.2 will appear. Change that line so it reads
'Chemical Identifiers.Chemical is equal to Chlorine.' Now the model will understand this
selection as selecting all releases that are 1) from facilities in New York, and 2) Benzene OR
Chlorine.

Note that the selection statements work similarly to outlines. How a line is indented shows you
what grouping it belongs to. The first line (the initial bracket statement) will always apply to
the entire selection, and all additional selection statements are nested within it. Refer to the
example selections at the end of this section for ideas on how to build complex selections with
multiple selection statements.

Deleting Selection Statements

To delete statements, click on the circle to the left of the text line you no longer want, then
click 'Delete Current Row'. If the text line you delete is a bracket statement with conditions
underneath it, those conditions will also be deleted. Note that the first bracket statement cannot
be deleted. Clicking on the Clear button will erase your entire selection.

'Special' Button

Under the Special button in the Select elements... screen, there are two options that allow you
to create two different types of selections with multiple condition statements quickly and easily.
The ' SIC code chain' option will automatically select all those facilities that report the 4-digit
SIC code you enter as any one of their six reported SIC codes. The 'Read Facility IDs from
File' option allows you to import a text file containing a list of TRI facility IDs that you wish to

formatting) with each facility ID followed by a hard return, and no hard return after the very
last entry. After entering either option, the model will add a sequence of condition statements to
the selection window. You can then further modify your selection.

Saving/Opening Selections

The RSEI model allows you to save your selection statements, so that you can either use the
selection again in a later analysis, or just use the selection statements as a starting point for a
similar selection. In the box at the bottom of the screen, beneath 'Enter Description' you can
enter a fairly lengthy text description of your selection that will be displayed the next time you
open it. Click the Save button at the top of the screen, and the selection will be saved to your
hard drive. Note that this only saves the selection itself, not the results of the selection. Next
time you open it (using the Open button at the top left), you will have to resubmit in order to
use the resulting set.

Submitting Your Selection

When you are finished building your selection, click Submit to run it. Depending on your
computer's memory (RAM) and the size of the requested set, your selection may take up to 30
minutes or longer to finish. Shorter selections, such as all facilities in one state for one year,
should be done in under five minutes.

Variable Descriptions

The following tables describe the variables and variable groups that you can use to build your
selection. Each table also provides the correct entry format for each variable, or notes that the
model contains a list to select from.

NOTE: It is important to use the entry format listed (e.g., use all capitals if indicated).
Otherwise, your selection will contain incorrect data, or will not return any results at all.

Chemical Flags

Chemical flags indicate whether a chemical is in a particular

group of interest. For example, as noted below, chemicals with primary or secondary drinking
water standards under the Safe Drinking Water Act contain the word 'True' in the SDWA Flag

i *Because there may be some variation in the spelling of city, county, or facility names in the TRI database,
you need to carefully consider your search criteria. Facility IDs are the most reliable way to select
individual facilities. Selecting facilities using Facility Name may provide unexpected results. For instance,
if you wish to select all Dow Chemical facilities, you might query releases where Facility Name contains
DOW. However, this will also select facilities such as ABC WINDOW CORP.

Facility Industry

A subset of all industries are required to report their releases to TRI. Specifically, all facilities
within 2-digit Standard Industrial Classification (SIC) codes 20 through 39 must report releases
(if those releases exceed given thresholds), and selected facilities within SIC codes 10, 12, 49,
51, and 73 must report their releases. A given facility may produce more than one type of
product or may be associated with more than one type of activity, and therefore, the facility
may report up to six SIC codes on TRI Form R, with one code designated as primary. Facilities
may submit multiple Form R's, and so potentially may report more than six SIC codes and
multiple primary codes.

Because sector-based analyses are an important component of RSEI, facility reporting data are
processed to make them easier to use. For any facility that has multiple primary SIC codes,

RSEI assigns the most frequently reported as SIC Code 1. If more than five additional SIC
codes are reported, RSEI assigns the five most frequently reported as SIC Codes 2 through 6.
Users can use the other fields to make selections at a more aggregated level (2 or 3-digit SIC
Codes). Note that if you choose to select releases using a numerical value in the 'SIC Code
Same 2 Digit' field, the model will not select facilities that have reported more than one 2-digit
SIC Code (in such cases the code shows 'MU,' 'MO' or 'MN'). For details on the processing of
the SIC Code data, see Technical Appendix F. See Standard Industrial Classification Codes for
a list of the industries associated with 2-digit and 3-digit SIC codes.

Beginning with RY 2006, TRI requires facilities to report their North American Industry
Classification System (NAICS) code. RSEI processes the NAICS code in the same way as SIC
codes are processed. TRI also maintains the SIC codes that each facility has historically
reported, and that information is contained in the facility table in RSEI; for reporters that are
new since RY 2006 who have reported only NAICS codes, RSEI crosswalks the NAICS to SIC

facilities report more than four NAICS codes.

information as reported by facilities to the TRI rather than information specific to the method
used to model releases in the RSEI Model. For example, there is a Media Code for releases to
the air from the facility stack (i.e., Stack Air), but there is no indication of whether the release
occurs in an urban or rural area (a distinction used in the air dispersion models).

CHAPTER 6: Selecting Releases

Examples of Complex Selections

The following examples explain how to build complex queries to answer specific questions.
Note that when building a complex query, the order in which you list condition statements does
not matter; what does matter is how you bracket them.

Example 1

Suppose you want to look at air releases of chemicals that are Clean Air Act pollutants or
Hazardous Air pollutants. You have already looked at California specifically, so you are not
interested in releases from that state. In addition, you have already looked at benzene and
toluene releases by themselves, so you would like to exclude them, too. Your selection would
look like the following:

Choose records where all of the following apply

1.	Facility Location. State is not equal to CA

2.	any of the following apply

2.1.	Chemical Flags. HAP Flag is equal to True

2.2.	Chemical Flags. CAA Flag is equal to True

3.	Chemical Identifiers.Chemical is not equal to Benzene

4.	Chemical Identifiers.Chemical is not equal to Toluene

5.	any of the following apply

5.1.	Release Media.Code is equal to 1

5.2.	Release Media.Code is equal to 2

Example 2

Suppose you want to look at a specific industry, for instance paints and allied products, SIC
code 2851. Because reporting facilities are allowed to report up to six 4-digit SIC codes, to be
sure that you select all of the facilities in the industry, it is safest to allow the selection of a
facility with that SIC code in any one of those six fields. Suppose you are also only interested in
releases of OSHA carcinogens, and only those facilities in Texas. Your period of interest is
1998 to the present, and you want to exclude large facilities that release over 1,000,000 pounds
annually. Your selection would look like the following:

Choose records where all of the following apply
1 .any of the following apply

1.1.	Facility Industry.SIC Code 1 is equal to 2851

1.2.	Facility Industry.SIC Code 2 is equal to 2851

1.3.	Facility Industry.SIC Code 3 is equal to 2851

1.4.	Facility Industry.SIC Code 4 is equal to 2851

1.5.	Facility Industry.SIC Code 5 is equal to 2851

1.6.	Facility Industry.SIC Code 6 is equal to 2851

2.	Facility Location. State is equal to TX

3.	Chemical Flags.OSHA Carcinogens is equal to True

4.	Submission.Total Pounds is less than 1000000

5.	Submission. Year is greater than 1998

1996-2010 TRI Data


-------
CHAPTER 6: Selecting Releases

Example 3

Suppose you want to look at a trend over time (1996-2007) in risk-related scores. As noted
previously, changes have been made to the TRI reporting requirements that need to be
accounted for when doing time trend analyses. The first change is that in 1998 TRI required
facilities in new SIC codes to report. These facilities must be excluded to get an accurate time
trend. The second change is that TRI has added and deleted chemicals from the list of
reportable chemicals, and changed how some chemicals are reported. RSEI includes a flag
called 'Core Chemical,' that marks only those chemicals that have been reported over the entire
time period of TRI reporting with no changes in the details of their reporting requirements.
RSEI also contains a flag called 'MiniCore Chemical,'which has the same practical effect in the
current version of the model as 'Core Chemical,', since RSEI does not contain TRI data for TRI
reporting years before 1996 (except upon request). In this example, you can use 'Core
Chemical.' In addition, if you are only interested in risk-related scores, you can limit your
selection to the media that are fully modeled (air, direct water, POTW and off-site incineration
releases). Your selection would look like the following:

Choose records where all of the following apply

1.	none of the following apply

1.1.	Facility Industry.SIC Code 1 is equal to 1021

1.2.	Facility Industry.SIC Code 1 is equal to 1031

1.3.	Facility Industry.SIC Code 1 is equal to 1041

1.4.	Facility Industry.SIC Code 1 is equal to 1044

1.5.	Facility Industry.SIC Code 1 is equal to 1061

1.6.	Facility Industry.SIC Code 1 is equal to 1099

1.7.	Facility Industry.SIC Code 1 is equal to 1221

1.8.	Facility Industry.SIC Code 1 is equal to 1222

1.9.	Facility Industry.SIC Code 1 is equal to 1231

1.10.	Facility Industry.SIC Code 1 is equal to 4911

1.11.	Facility Industry.SIC Code 1 is equal to 4931

1.12.	Facility Industry.SIC Code 1 is equal to 4939

1.13.	Facility Industry.SIC Code 1 is equal to 4953

1.14.	Facility Industry.SIC Code 1 is equal to 5169

1.15.	Facility Industry.SIC Code 1 is equal to 5171

1.16.	Facility Industry.SIC Code 1 is equal to 7389

2.	Chemical Flags.Core Chemical Flag is equal to True

3.	any of the following apply

3.1.	Release.Media Code is less than or equal to 3

3.2.	Release.Media Code is equal to 6

3.3.	Release.Media Code is equal to 750

3.4.	Release.Media Code is equal to 754

Because it is always a good idea to exclude the new industries and include only the core
chemicals when doing a time trend analysis, this is a very useful selection. It saves the need to
retype the selection statements each time you do a time trend if you save the first two
statements (everything up to '3. any of the following apply') the first time you type them, by

again, which will take a few minutes to complete. The status bar at the bottom left of your
screen will inform you of what the model is doing.

The Selected Facilities List

The list at the top of the screen shows all the facilities that have at least one release in the
selected set. For each facility, the list shows its TRI facility ID number, the facility name, the
city, state and ZIP code of the facility, its latitude and longitude, and the total score for the
facility in 2007. The default sort order of the list is by TRI Facility ID. However, by clicking on
the header for any column, you can sort the list by that column's variable. A grayed-out arrow
will appear in the right-hand corner of the header to show you that the list is sorted by that
column. Note that if a facility is highlighted before sorting, it will remain in the display
afterward. If you want to see the beginning of your list, use the arrow buttons to scroll up to the
beginning.

The list works like a directory tree (such as in Windows Explorer) that you can expand or
collapse by double-clicking on rows (or by clicking on the plus or minus sign at the far left of a
highlighted row). To open up a level in the Selected Facilities List, either double-click on the
desired entry, or click on the entry once to highlight it, then click on the plus sign at the far left
of the row. Clicking on a plus sign will not work if the entry is not highlighted first. If you
double-click on a facility in the list, you will see two entries below that facility: 'Submissions'
and 'Full Facility Record.' Double-click on the 'Full Facility Record' to get a complete listing
of all the information contained in the model about that particular facility.

If you double-click on 'Submissions,' you will get a full listing of all of the facility's TRI
submissions. Those submissions that are included in your selected set will be highlighted in
green. The default sort order for these releases is by DCN (the Document Control Number
assigned by TRI), but, like the facility list, you can double-click on any column's header to sort
by that column. For each submission, this list displays DCN, the year of the submission, the
chemical name, its use and Max Onsite codes (see On-site Chemical Information in Chapter
10 for explanations of codes), the total pounds released, and the inhalation and oral toxicity
weight for the chemical. If you double-click on a submission that has a nonzero entry for 'Total
Pounds,' an entry titled 'Releases' will appear. Double-click on that entry, and 'Media Text'
will appear. Double-click on any of the 'Media Text' entries that appears, and the screen will
display an entry called 'Scores.' Double-click on that, and the 'Scores' screen will display the
total pounds, total score, population affected and the score category text. If the score is zero, the
score category text will inform you of the reason the release could not be modeled.

To return to a previous level, simply click on the minus sign to the left of each entry, and the
entry will be hidden. Either double-click on the entry, or click on the plus sign to show it again.

If you find a certain facility that you would like more information on and you wish to make a
new selection including that specific facility, you can copy the TRI ID in order to paste it into
the selection statement. Simply highlight the row in the Selected Facilities List containing the
desired TRI ID, and right-click on it. Nothing will noticeably change in the display. But you can
then press Control-C, which will copy the TRI ID to the Windows clipboard. Once the TRI ID
is on the clipboard, you can paste it anywhere, including the Select Elements... screen, or even

Changing the Grouping

The default organization is to list facilities singly. However, if you want to group them, for
instance by state, you can. Just click on the column header that you want to group by, such as
' State,' and drag it up to the darker gray bar at the top of the screen and drop it there. Then the
list will show an entry for each state in your selection. If you double-click on a state, the list
will expand to show all the facilities in that state. The rest of the list works as described above.

You can also group on more than one column variable. For instance, you may want to group
first on state, then on city. Click and drag 'State' first, then 'City' and the model will show
them linked in the gray bar at the top of the screen. The collapsed list will show all states in
your selection. If you click on a state, a list of all cities in that state in your selection will be
displayed. Then if you click on a city, a list of all the facilities in that state will be displayed.

CHAPTER 7: Displaying Selected Facilities - The Selected Facilities Browser

Using Map Functions

The map is shown in the bottom left of the Selected Facilities Browser. The buttons you can
use to navigate and modify the map are in the bottom right. The Map works with the list of
selected facilities at the top of the screen. All TRI reporting facilities are shown as purple
circles on the map. As described below, you can select an option to make facilities in your
selected set appear larger and darker purple. Off-site facilities are shown as yellow squares.

Icons and Map Information

Finding a Location (Position)

%

The default view of the map is the continental U.S. view. Alaska and Hawaii are not shown in
the initial map but are available in other views (see below for details). The information to the
right of the Map View screen describes the current map. You can click on any part of the map
with the mouse.

When the Position button is highlighted the following information is displayed:

•	Latitude and Longitude refer to the last point where the cursor was placed on the map
(latitude and longitude will change as the cursor is moved);

•	North-South and East-West express the kilometers that can be viewed along each axis in the
current map;

•	Area shows the square kilometers shown on the current map;

•	Altitude reflects the zoom level of the current map, and is approximately the kilometers that
can be viewed in the width of the screen;

•	Information shows, in the bottom right-hand window, a list of geographic and demographic

Click on the U.S. map icon to zoom back to the full continental U.S. view. You can also zoom
into a particular area by drawing the diagonal of a square with the cursor while holding down
the right mouse button.

You can move the map by left-clicking on the map and dragging the cursor in the direction that
you want the map to move. There will be a slight time delay as the map adjusts itself. In this
way you can move the map to view Alaska, Hawaii and the territories.

Retrieving Information

To retrieve geographic information about a point on the map, click the Identify icon then click
on any point on the map. In the Information box geographic and demographic data for the
selected point will be displayed. Displayed data include locational information like latitude and
longitude, state, county, and nearby geographic features; population data from the U.S. Census
Bureau (at the grid-cell level); and data on nearby TRI reporting facilities. (See the tables of
variable descriptions in Chapter 5 for an explanation of the information displayed here.)

Highlighting Selected Facilities

/Ik

When you open the Selected Facilities Browser, the map will only show the facilities in your
selected set. On-site facilities will be shown as purple circles. Off-site facilities will be shown
as yellow squares. If you click on the 'Toggle highlight of selected facilities,' the remaining
facilities not in your selected set will also be shown. Nonselected onsite facilities will be shown
as light purple circles. Nonselected offsite facilities will be shown as white squares.

handful of facilities. To remove the facility names, simply click on the button again.

Displaying the Map Legend 1M

For help with any of the symbols used on the map, click on the Display Legend icon at the far
right of the row of icons. This will display a pop-up window with short descriptions of each of
the symbols used to represent physical and political entities, such as roads, streams, and
boundary lines for states, counties and tribal lands. To hide the window once it is displayed,
either click on the small 'x' in the upper right corner of the window, or simply click on
anything else on the screen outside the window. The window can also be moved anywhere else
on the screen by clicking and dragging the top title bar.

CHAPTER 8: Snapshots of Selected Releases - Summary and Thematic Maps

CHAPTER 8

Snapshots of Selected Releases - Summary and
Thematic Maps

The Summary and Thematic Maps buttons, found in the second row of menu buttons, provide quick
standard ways to look at the set of releases you selected using the Select button. The Summary button
lets you quickly see graphs of total score and pounds by year, and year by media, as well as ranked
lists of chemicals released and facilities. These options are frequently requested analyses, but may not
be exactly what you want. More customized functions can be found under the Custom Tables button,
as explained in Chapter 9.

The Summary Button

There are five options under the Summary button. Each is explained below.

• Total by Year. This button brings up a
Preformatted graph that shows the
combined score and pounds for all
releases in the selected set. There are
two bars for each year in your selection.
The red bar on the left displays the total
score for the year indicated underneath
the bars.The total score is shown in a
yellow box above the red bar, and is
measured using the scale on the left
side of the graph. The green bar on the
right displays total pounds for the year
indicated. The total score is shown in a
yellow box above the green bar, and is
measured using the scale on the right
side of the graph. If your selection only
includes one year, the graph will only
show the two bars.

• Year by Media. This button uses the
same color scheme and scales as Total
by Year. But in this case the horizontal
axis shows media instead of year. The
graph only shows one year at a time,
which can be changed in the ' Select
Year' box located above the graph.

Year by Media Graph

• Chemical Rank. This button shows all
of the chemicals in the set of selected
releases, ranked in order of highest
score (risk-related result) first. This
table only shows one year at a time,
which can be changed in the ' Select

CHAPTER 9: Analyzing Selected Releases - Custom Tables

CHAPTER 9

Analyzing Selected Releases - Custom Tables

The Custom Tables button allows for the display of information in many different ways. Like
the Selected Facilities Browser, custom tables work from the data set selected using the Select
button.

You can construct a table using any variables in the model (including variables that were not
used in your selection), change the rows and columns, examine different statistics, sort the data,
and cut the data in many different ways.

Creating a New Table

Click New Table to create a new table based on your selected data. This will bring up the
Select Dimensions dialog. Here you can select the variables that will be displayed in your new
table. The variable names are in the format Category.Variable. There are five categories:
Chemical, Facility, Submission, Release, and Element. Each variable is associated with a
category. For instance, Chemical.CAS Number refers to the CAS number variable, which is
in the Chemical category. Check the boxes next to the variable name to include the variable in
your crosstab table. There is no firm upper limit on how many variables you can select. It
depends on how many values each variable can show, and how much data will be displayed on
the screen. If your table is too large or too complicated to be displayed you will see a 'list index
out of bounds' error, and the model will not display the table. However, the table is often
completed, and can be found in the 'RSEI Results' folder under your Windows Users directory,
as a Paradox table with .db extension.

Enter a name for your table in the box at the bottom of the screen. Note that file names cannot
include any of the following characters: forward slash (/), backslash (\), greater-than sign (>),
less-than sign (<), asterisk (*), question mark (?), quotation mark ("), pipe symbol (|), colon (:),
or semicolon (;). If you attempt to enter any of these characters, the model will not accept it. If
this is not your first table, the name must be different than the previous table; the model will
not overwrite what is currently showing. The table will be saved to the 'RSEI Results' folder
under your Windows Users directory as a Paradox table with a .db extension.

The model will make the first variable selected the column variable, and the rest will be row
variables; however, you can change the order once the table is displayed (see Modifying the
Table View). Hit Run!, and the table will be displayed in the window. Depending on how big
your selected data set is and how complicated the table you requested is, it may take anywhere
from 30 seconds to 30 minutes to display the table.

The new table is saved so that it can be loaded for future use. You can click the New Table
button again to make a different table (using the same set of selected facilities). The row and
column options you selected previously will still be checked, so be sure to deselect them if you
do not want them included in your next table. The name of the table currently showing appears
to the right of the third row of menu buttons.

Custom Crosstab Table

Note that when your new table is displayed, it may show only one row variable and one column
variable. Any additional row and column variables that you have selected may be hidden. Click
on the small yellow plus sign on the right side of the row variable to show the additional
variables. The table is fully expanded when the last row or column does not show a small
yellow plus sign on its right edge. It will be faster to re-display your table if you leave the row
and column variables hidden when not viewing them. The values in black in the table represent
the value as shown in the Value Selected box. For instance, if the box displays Risk-related,
the value in black in each cell is the risk-related score. The value in red beneath it is the Total
Percent, that is, the percent of the total value of the table for that summary that is contributed
by that cell. You can remove the Total Percent display or add additional percentage displays
by using the Options button.

Loading a Table

Every new table that you create and name is saved to your hard drive, in the 'RSEI Results'
folder under your Windows Users directory. To load any table you have previously created,

Version 2.3.1	114	1996-2010 TRI Data

May 2012


-------
CHAPTER 9: Analyzing Selected Releases - Custom Tables

simply click on the Load Table button, and select the desired table. Note that loading a table
will only change the data in the Custom Table functions (New Table, Graph and Sorted
Table functions). The last underlying set that you selected using the Select button will still be
the active set for all the other functions. To see the set that was used in the generation of the
table that is presently loaded, click on the table name, and you will see a window with the
selection statements used for that set. Remember, if you want to see the selection being used for
all of the other functions, you can click on the text displaying the number of selected facilities,
releases, and elements in the upper right corner of your screen to see the selection statements
for that set.

Once you have loaded the table, you can modify it as you would any new table you create.

Modifying the Table View

To switch the rows and columns, simply click and drag one row or column heading over the
heading of the row or column heading you would like to switch with it. Hold down the mouse
button until a double arrow sign appears over the heading . Then release the mouse button and
drop the heading. To move columns or rows, click on the heading of the row or column you
want to move, and drag it next to the row or column heading where you would like to add it,
until you see two arrows pointing at each other. Then release the mouse button. Note that you
can only move variables that are open and showing. However, it will increase the speed of
moving rows and columns if you collapse any variables that are not being moved.

To switch a row \ ariaMc with a column \ ariaMc (or \ ice \ crsa) click and
drag the heading of one \ariaMc and drop il 011 lop of the oilier heading.

Collapsing and Expanding Rows

Any column can be resized by using the mouse to move to the right-hand border of the heading
of the column you wish to size, until the arrow becomes a double line with two arrows. You
can then move the mouse to the right to make the column wider or move the mouse to the left
to make the column narrower. The row heights can be resized in a similar way. The row widths
cannot be resized.

Using the Filter

In addition to collapsing rows and columns, you can also control how your data are displayed
by using the Filter option. The Filter option allows you to select specific values for the
variables in your table. Once filtered, only the selected values will be displayed, allowing you
to focus on specific entries. For instance, if you create a table with state and media text as
variables, you can set the filter to show only states in EPA Region 1.

Click on the Filter button at the top of the Tables screen. This brings up the Set Filter dialog.
In the first window, select the variable you would like to filter by clicking on its name. This
will bring up a list of values in your table from which you can select filter parameters. Click on
the box next to any of the values that you would like to see displayed in the table, then click

CHAPTER 9: Analyzing Selected Releases - Custom Tables

Apply Filters. The Crosstab table will be shown, using only the values you selected for the
variables you modified. To remove the filter, click Filter again, then click Clear this filter,
then Apply Filters. Filters for multiple variables can be selected, at the same time, or in
succession. Simply click on each variable in the Set Filter dialog, and then select the values
you are interested in. You can clear one filter by highlighting the variable in the top window,
then clicking Clear this filter. Clear all filters by simply clicking Clear all filters.

The filters in effect at any time are shown at the bottom of the Set Filter dialog.

Value Selected

In this window you can select how you want to express the data in your table. You can choose
from pounds-based, hazard-based, or full risk-related results. Each option gives a different
perspective on the reported releases and transfers. Descriptions of these selections are:

Count of Elements. This number reflects the total number of individual Indicator Elements.

Count of Releases. This number reflects the total number of individual releases. The number
of releases for some media is slightly less than the number of elements, because some releases
(such as those to surface water) end up partitioned between two or more pathways (fish
ingestion and drinking water in the case of surface water).

Count of Facilities. This is the total number of facilities.

TRI Pounds. This number reflects the number of pounds released or transferred that are
reported to the Toxics Release Inventory for the exposure pathway being considered. [Note:
When 'Element.Category Code' or 'Element.Category Text' is used as column or row variable
in a custom table, the TRI Pounds shown for the direct water, POTW effluent, and fish
ingestion categories are modeled apportionments of the total pounds for a direct water release.
While these apportionments will sum to the correct total for a water release, the ratio of score
categories is only for modeling purposes.]

TRI Pounds with Toxicity Weights. This value shows only TRI pounds for the chemicals that
have toxicity weights. This value differs from Modeled Pounds because it includes those
chemicals which have toxicity weights regardless of whether they have physicochemical
properties.

Hazard. This value is TRI pounds multiplied by the toxicity weight of the chemical appropriate
for the exposure pathway selected. The inhalation toxicity weight is used for releases or
transfers to media 1 (fugitive air), media 2 (stack air), media 750 (off-site incineration), and
media 754 (off-site incineration- no fuel value). The oral toxicity weight is used for releases
and transfers to media 3 (direct water) and 6 (transfers to POTWs) (see Chapter 10 for a list of
modeled media). For releases that are not modeled (because the pathway is not modeled or
because other necessary data, such as physicochemical properties, are lacking), the higher
toxicity weight is used.

Modeled Pounds. This number reflects the number of pounds released or transferred (TRI
Pounds) that can be modeled. Reasons that releases may not be able to be modeled include lack

CHAPTER 9: Analyzing Selected Releases - Custom Tables

of physicochemical information required for exposure modeling or lack of toxicity weights

Modeled Hazard. This value is modeled pounds multiplied by the toxicity weight of the
chemical appropriate for the exposure pathway selected. It does not measure how the chemical
moves through the environment and comes in contact with an individual. The inhalation
toxicity weight is used for releases or transfers to media 1 (fugitive air), media 2 (stack air),
media 750 (off-site incineration), and media 754 (off-site incineration- no fuel value). The oral
toxicity weight is used for releases and transfers to media 3 (direct water) and 6 (transfers to
POTWs) (see Chapter 10 for a list of modeled media).

Modeled Hazard*Pop. This value is the number of modeled pounds multiplied by the toxicity
weight of the chemical appropriate for the exposure pathway selected and by the population
potentially exposed. The inhalation toxicity weight is used for releases or transfers to media 1
(fugitive air), media 2 (stack air), media 750 (off-site incineration), and media 754 (off-site
incineration- no fuel value). The oral toxicity weight is used for releases and transfers to media
3 (direct water) and 6 (transfers to POTWs) (see Chapter 10 for a list of modeled media). Also
note that Modeled Hazard*Pop uses total population only, and is not available for
subpopulations.

Risk-related Results - Children Under 10. This value is the product of the surrogate dose
(estimated using exposure models), the chemical's toxicity weight, and the population under 10
years of age. The pounds used in this result differ from the pounds used for Modeled
Hazard*Pop (and may be a smaller value) because the fate and transport of the chemical
pounds have been modeled and exposure assumptions have been made.

Risk-related Results - Children 10 to 17. This value is the product of the surrogate dose
(estimated using exposure models), the chemical's toxicity weight, and the population from 10
to 17 (inclusive) years of age. The pounds used in this result differ from the pounds used for
Modeled Hazard*Pop (and may be a smaller value) because the fate and transport of the
chemical pounds have been modeled and exposure assumptions have been made. Also note
that Modeled Hazard* Pop uses total population only, and is not available for subpopulations.

Risk-related Results - Males 18 to 44. This value is the product of the surrogate dose
(estimated using exposure models), the chemical's toxicity weight, and the male population
from 18 to 44 (inclusive) years of age. The pounds used in this result differ from the pounds
used for Modeled Hazard*Pop (and may be a smaller value) because the fate and transport of
the chemical pounds have been modeled and exposure assumptions have been made. Also note
that Modeled Hazard* Pop uses total population only, and is not available for subpopulations.

Risk-related Results - Females 18 to 44. This value is the product of the surrogate dose
(estimated using exposure models), the chemical's toxicity weight, and the female population
from 18 to 44 (inclusive) years of age. The pounds used in this result differ from the pounds
used for Modeled Hazard*Pop (and may be a smaller value) because the fate and transport of
the chemical pounds have been modeled and exposure assumptions have been made.

Risk-related Results - Adults Over 65. This value is the product of the surrogate dose
(estimated using exposure models), the chemical's toxicity weight, and the population over 65
years of age. The pounds used in this result differ from the pounds used for Modeled

CHAPTER 9: Analyzing Selected Releases - Custom Tables

Hazard*Pop (and may be a smaller value) because the fate and transport of the chemical
pounds have been modeled and exposure assumptions have been made.

Risk-related Results. This value is the product of the surrogate dose (estimated using exposure
models), the chemical's toxicity weight, and the population. The pounds used in this result
differ from the pounds used for Modeled Hazard*Pop (and may be a smaller value) because
the fate and transport of the chemical pounds have been modeled and exposure assumptions
have been made.

Examples of useful comparisons among the above results include:

1.	TRI Pounds vs. TRI Pounds (with toxicity)

This comparison allows you to determine the proportion of total TRI Pounds released that are
associated with chemicals that have toxicity weights. This proportion may be somewhat
different than the overall proportion of TRI chemicals that have toxicity weights. For example,
50% of a given set of TRI chemicals may have toxicity weights. However, it is possible that
80% of the TRI Pounds released for the same set of chemicals may be associated with
chemicals that have toxicity weights.

2.	TRI Pounds vs. Modeled Pounds

This comparison allows you to determine the proportion of chemical releases for which risk-
related impacts can be estimated using the Risk-related option.

3.	Hazard vs. Modeled Hazard

This comparison shows you (a) the amount of toxicity-weighted releases associated with
chemicals that have toxicity weights versus (b) the amount of toxicity-weighted releases for
chemicals that have both toxicity weights and physicochemical data that are used to model
exposure. An important difference between this comparison and the comparison in example (2)
above is that this comparison addresses only those chemicals that have toxicity weights.

4.	Modeled Hazard vs. Modeled Hazard * Pop

This comparison allows you to determine the extent to which total population contributes to the
result. However, no exposure modeling is considered in this crude approximation.

Within the model, you can only display one type of summary in a custom table at a time.
However, if you export the table to another format such as Microsoft Excel or Lotus 1-2-3, you
can work with all of the data at once. Simply click on the Export button at the top of the screen
(see below for details on exporting).

Options

These selections allow you to modify how values are expressed in the table.

Normalization

For any of the summaries selected except TRI Pounds, you can choose to normalize the RSEI

results. Click Options, then 'Normalization,' then 'National.' The value shown in each cell is
that cell's portion of the national value for that year, divided by the total value for 1988 and
multiplied by 100,000. In this way, each national summary (i.e., Risk-related, Modeled
Hazard) for 1988 is 100,000, and any other selection is displayed as a percentage of that.

Cell Display

This option will display additional values in your table (underneath each current cell value) that
shows how that cell's value contributes to different portions of the aggregate table value. The
default display includes the first three options listed below, Total Percent, Column Percent,
and Row Percent. To turn them off, simply click on each one to remove the check mark.
Clicking on them again will turn them back on. The box in the upper left corner of the table
shows the color of each cell display option.

Total Percent. The percent contribution of the current cell to the total table sum. For instance,
if the 'Risk-related' summary is selected, a cell's total percent value (shown in red) would be
that cell's risk-related score divided by the sum of all cells. The sum of all the cells in the table
is shown in the bottom right corner in black.

Row Percent. The percent contribution of the current cell to the total row sum. If the Risk-
related summary is selected, a cell's row percent value (shown in green) would be that cell's
risk-related score divided by the sum of all cells in that row, as shown in far right cell in that
row in black.

Column Percent. The percent contribution of the current cell to the total column sum. If the
Risk-related summary is selected, a cell's total percent value (shown in blue) would be that
cells risk-related score divided by the sum of all cells in the column, as shown in the bottom
cell in the column in black.

Percentile. The percentile that the cell's value falls into, when all of the cell values in the table
are taken into account.

Rank. The cell's rank, from highest (1) to lowest, of all of the cell values in the table.

Graph

The Graph function allows you to quickly create a pre-formatted graph based on the current
Custom Table. The Graph works from your current display, not from the underlying table, so
if columns or rows are collapsed, they will not be included. Also, if you have used the filter to
select certain values of your variables, the excluded variables will not be shown on the graph.
Whatever summary statistic (TRI pounds, Risk-related, etc.) is showing will be used. You can
go back and forth between the two screens. Anything you change in the Custom Table will
automatically be updated and displayed in the Graph.

Custom Graph

If your table is very large or contains many variables, the model will attempt to graph it, but the
graph may not legible. If this is the case, simply collapse rows and/or columns, or use the Filter
option to reduce the number of values that need to be displayed on the graph.

If you choose to print your graph (using the Print button at the top of the screen), you can add a
title for it by clicking on the Edit Title button above the graph, and typing in the desired text.

The footnote that will be printed on your Graph is shown in blue below the graph. The default
footnote shows the RSEI model version number, the file name of your table, and the model
selection (summary) that is being graphed. You can change this footnote by clicking the Edit
Footnote button above the graph, and typing in the desired text.

You can also change the font size for both the title and the footnote in the box above the graph.

Sorted Tables

The Sorted Table option allows you to display your table in the form of a sorted list. Like the
Graph function, the Sorted Table works from whatever you have displayed on the Custom
Table at the time. Each table cell showing is given one entry in the list, which is sorted in

Custom Sorted Table

The Sorted Table is very useful when looking at large complicated tables. It shows very
quickly what cells are of most concern, and for how much of the total the top few entries are
responsible. If you have a table with several row variables, for instance, you can quickly zoom
in on the area of most concern by collapsing the table to one row and one column, and then
clicking Sorted Table to find which value of the first row or column variable is of most
concern. Then you can expand the table and look at a more detailed breakdown for that value.

Exporting Tables

Any table can be exported to a variety of formats, including Dbase, Lotus 1-2-3, Microsoft
Excel, and text. Exporting can be very useful for a variety of reasons. One of the most common
uses is to be able to compare the different model summaries, as listed under Value Selected.
The advantage in using exported tables is that all of the summaries are visible at the same time,

Version 2.3.1

CHAPTER 9: Analyzing Selected Releases - Custom Tables

so you can compare them, and make new calculations with them.

To export a table, click on the Export button. Select the file type. Depending on what type you
select, some options will be grayed out and some will be active. Select the options you would
like of the ones that are active. Name the file in the 'Export to file' box, and click the file icon
next to the name box to select a directory for your saved file. The 'RSEI Results' folder under
your Windows Users directory is a convenient place provided to store model output files. Click
OK, and the file will be saved in that directory.

Exported Custom Table

Note that file names cannot include any of the following characters: forward slash (/), backslash
(\), greater-than sign (>), less-than sign (<), asterisk (*), question mark (?), quotation mark ("),
pipe symbol (|), colon (:), or semicolon (;). If you attempt to enter any of these characters, the
model will not accept it. Note that all of the summaries are listed (not just the summary shown
on the screen when the table was exported). Unlike other custom table functions, the table
export does not change with what is shown on the screen at the time.

Printing Tables

Any table can also be printed. Simply click Print on the top menu, and the currently displaying
table will print to your installed default printer. Note that large complicated tables may not print
well directly from the program. If this is the case, it may be easier to first export the table to a
database or spreadsheet program where more formatting is possible, and then print it from that
program.

CHAPTER 11: Glossary of Commonly Used Terms

CHAPTER 11

Glossary of Commonly Used Terms

core chemicals

Those chemicals and chemical categories which have been on the TRI List since 1987 and for
which there have been no changes in reporting requirements. In RSEI Version 2.3.1, core
chemicals are not differentiated from mini-core chemicals, as this version does not contain TRI
reporting data for years prior to 1996.

chronic human health

The RSEI model addresses both chronic effects and chronic exposures related to human health.
Chronic effects are those that generally persist over a long period of time whether or not they
occur immediately after exposure or are delayed. Chronic exposure refers to multiple exposures
occurring over an extended period of time, or a significant fraction of an individual's lifetime.

EPCRA

The Emergency Planning and Community Right-to-Know Act of 1986, which is the third part
of the Superfund Amendments and Reauthorization Act of 1986, also known as SARA Title III.

exposure modeling

RSEI's risk-related results include a calculated surrogate dose, which is estimated through
exposure modeling. Exposure modeling is a way to track a chemical's fate and transport
through the environment, until it comes to a point of contact with an exposed person. Exposure
modeling includes using standard assumptions about human exposure to contaminants, such as
the drinking water, fish ingestion, or air inhalation rate.

exposure pathway

The exposure pathway is the physical course that a chemical takes from its emission by the
facility to the exposed individual and is related to the type of release. RSEI models fugitive and
stack air releases and fish ingestion and drinking water intake from releases to surface water.

exposed population

The exposed population is the population that is likely to come in contact with a chemical. The
population differs depending on the exposure pathway modeled. For instance, the population
exposed to chemicals released to air is the population in a circle with radius of 49 km
surrounding the facility.

flag

A True/False field in the RSEI databases used to designate chemicals or facilities included in
various EPA programs or with certain other characteristics.

CHAPTER 11: Glossary of Commonly Used Terms

Form R

EPA's Toxics Release Inventory (TRI) collects information on chemical releases and transfers
from reporting facilities every year. The form these facilities fill out is called Form R. Facilities
may also fill out a certification statement, called Form A, which certifies that the facility's use
of a specific toxic chemical does not meet the minimum threshold requirement, and so is not
subject to Form R reporting.

full trend

A set of RSEI results for TRI Reporting Years 1988-2002. In order for the results to be
meaningful, the results only include core chemicals and original industries.

geocoding

Geocoding is the process of assigning latitude and longitude to a point, based on street
addresses, city, state and zip code. RSEI uses geocoded data for both on-site and off-site
facilities to better locate the facilities on the model grid. Geocoding services are provided by
Thomas Computing Services (TCS), using Matchmaker software.

grid cell

An 810m by 810m square defined by the (X,Y) coordinates of its center point. The set of grid
cells (the grid system) describes the U.S. and its territories and provides the geographical basis
of the RSEI model.

hazard-based

RSEI produces three main types of results: pounds-based, hazard-based, and risk-related.
Hazard-based results can be calculated for any set of chemical releases and transfers included in
the model, and consist of the pounds released multiplied by the chemical's toxicity weight.
Hazard-based results do not include any exposure modeling or population estimates.

health endpoints

An effect of exposure to a toxic chemical, such as carcinogenicity or reproductive toxicity,
indicator element

The building block of the RSEI model. A unique combination of facility, chemical release,
year, release pathway, and exposure pathway. Each Indicator Element has a set of results
associated with it. If the element cannot be modeled, then the score is zero; if there is no
toxicity weight available, then the hazard-based results are also zero.

inhalation unit risk

The upper-bound excess lifetime cancer risk estimated to result from continuous exposure to an
agent at a concentration of |g/m3 in air.

MCL

Maximum Contaminant Level, the highest concentration allowed by the federal government in
drinking water. MCLs are set using the best available treatment technology and taking cost into
consideration.

CHAPTER 11: Glossary of Commonly Used Terms

media

Path through which a chemical is released into the environment, such as direct water, POTW
transfer, fugitive air, etc. See Media Information for a full list of the media included in the
RSEI model.

mini core

Those chemicals and chemical categories which have been on the TRI List since 1995 and for
which there have been no changes in reporting requirements. In RSEI Version 2.3.0, core
chemicals are not differentiated from mini-core chemicals, as this version does not contain TRI
reporting data for years prior to 1996.

mini trend

A set of RSEI results for TRI reporting years 1995-2002. In order for the results to be
meaningful, the results only include mini core chemicals and original industries.

modeled media

The media for which full risk-related modeling is conducted in the RSEI model. These media
include the following: 1-Fugitive Air, 2-Stack Air, 3-Direct Water, 6-POTW Transfer, 750-
Offsite Incineration/Thermal Treatment, and 754-Offsite Incineration (No fuel value).

modeled hazard

The number of modeled pounds multiplied by the toxicity weight for the appropriate exposure
pathway (e.g. inhalation toxicity weight for an air release).

modeled pounds

Pounds reported by the facility that are modeled and accounted for in the risk score. Reasons
that pounds may not be modeled include gaps in toxicity data, data needed for exposure
modeling, data for the releasing facility, or other data necessary for modeling.

NAICS codes

North American Industry Classification System codes (NAICS) are used by business and
government to classify facilities that use the same production processes. NAICS codes are
designed to replace SIC codes, and TRI first required facilities to report NAICS codes instead
of SIC codes in RY 2006. See NAICS codes for a list of codes and descriptions.

normalization

In the RSEI model, it is possible to express the results normalized to 1988, the first year of data
collected by TRI. Reported TRI pounds cannot be normalized.

off-site

Off-site facilities (or receiving facilities) receive transfers of chemicals from TRI on-site (or
reporting) facilities. Types of off-site facilities include waste brokers, publicly-owned treatment
works (POTWs), recycling facilities, landfills, and hazardous waste facilities. Transfers to off-
site facilities are reported by the on-site facility transferring them.

on-site

On-site facilities (also called reporting facilities) report directly to TRI, and include

Version 2.3.1

1996-2010 TRI Data


-------
CHAPTER 11: Glossary of Commonly Used Terms

manufacturing facilities, metal and coal mines, electric utilities, chemical waste facilities,
chemical wholesalers, and petroleum bulk stations and terminals. Almost 50,000 on-site
facilities have reported to TRI since reporting was required in 1988.

oral slope factor

The Oral Slope Factor represents the upper-bound (approximating a 95% confidence limit)
estimate of the slope of the dose-response curve in the low-dose region for carcinogens. The
units of the slope factor are usually expressed as (mg/kg-day) -1.

original industries

Those industries which were required to report to TRI beginning in Reporting Year 1988, SIC
codes 20 through 39.

POTW

Publicly-owned treatment works (POTWs) are public wastewater treatment facilities that
receive wastewater, usually through a pipe system, from facilities using toxic chemicals.
Because of the unique treatment system, POTWs are modeled separately from other off-site
facilities.

pounds-based

RSEI produces three main types of results: pounds-based, hazard-based, and risk-related.
Pounds-based results are simply the amount of pounds released or transferred by TRI facilities.

reach

A reach is an unbranched linear segment of a water body with fairly constant hydrological
characteristics. A reach can be part of a stream, creek, river, pond, or lake.

RfC

The Reference Concentration is an estimate (with uncertainty spanning perhaps an order of
magnitude) of continuous inhalation exposure to the human population (including sensitive
subgroups) that is likely to be without an appreciable risk of deleterious noncancer effects
during a lifetime.

RfD

The Reference Dose is an estimate (with uncertainty spanning perhaps an order of magnitude)
of daily exposure [RfD] to the human population (including sensitive subgroups) that is likely
to be without an appreciable risk of deleterious noncancer effects during a lifetime.

risk-related

RSEI produces three main types of results: pounds-based, hazard-based, and risk-related. Risk-
related results combine surrogate dose with toxicity weight and population estimate, producing
a unitless value proportional to risk-related impact. Risk-related results (or scores) are not
independently meaningful and should only be used comparatively in relation to other model
results.

RY

The Reporting Year corresponds to the calendar year (January 1 to December 31) for which

Version 2,3,1	164	1996-2010 TRI Data

May 2012


-------
CHAPTER 11: Glossary of Commonly Used Terms

facilities report release and other waste management activities in their Form Rs.
score

A score is the numerical value in RSEI's risk-related results, combining surrogate dose,
toxicity, and population estimates. Scores are not independently meaningful and should only be
used comparatively in relation to other model results.

selection statement

A selection statement is used to select releases to analyze, in the Select Elements... screen. It
consists of at least one bracket statement and one condition statement.

SIC codes

Standard Industrial Classification codes classify a business or facility according to its primary
kind of activity, such as chemical manufacturing or electricity generation. Two-digit codes are
the most general, four-digit codes are the most specific (although some unofficial sources use
codes up to eight digits); RSEI uses two-digit and four-digit codes.

stream path

The course taken by a chemical release from its release point (an effluent pipe from a facility or
POTW) to the point where it is no longer modeled (up to 300 km).

surrogate dose

A surrogate dose is specific to a combination of facility, chemical release, media, release
pathway and exposure pathway. It is calculated in several steps. First, exposure and release
pathway-specific chemical release volumes are combined with physicochemical properties and
site-specific characteristics in models to estimate an ambient concentration in the
environmental medium of concern. The ambient media concentration is then combined with
standard human exposure assumptions (for adults and children) to estimate the magnitude of
the dose.

toxicity weight

This weight is a proportional numerical weight applied to a chemical based on its toxicity. The
toxicity of a chemical is assessed using EPA-established standard methodologies. For each
exposure route, chemicals are weighted based on their single, most sensitive adverse chronic
human health effect (cancer or the most sensitive noncancer effect). In the absence of data, the
toxicity weight for one pathway is adopted for the other pathway. The range of toxicity weights
is approximately 0.02 to 500,000,000.

trend

Any set of RSEI results across two or more years. In the RSEI model, users can use the
chemical flags (Core, Mini Core, and 1998 Core) to select the appropriate chemicals for the full
trend (1988 through 2010), the mini trend (1995 through 2002) or the trend for 1998 through
2002. The chemical flags automatically exclude reports for chemicals for which reporting
requirements have changed over the relevant time period. Because RSEI Version 2.3.1 includes
TRI data for 1996-2010 only, the Core flag (full trend) produces the same results as the Mini
Core (mini trend).
