I. ECOLOGICAL SUMMARY
The ecological risk assessment workgroup evaluated the residual risk posed by the 22
environmental problem areas identified by EPA Headquarters and the Regional Comparative
Risk (RCRP) directors. We evaluated residual risk at the ecoregion level (Omernik, 1986) for
the following reasons:
1. it was geographically and ecologically based;
2. the ecoregions could serve as a template for data collection ;
3. this approach tended itself well to geographic information system applications;
4. there are a wide variety of ecoregions within our five state region (portions of twenty-
five ecoregions);
5. we were concerned about the general health of the large ecological units recognizable in
the landscape; and
6. there was a short time frame to complete our initial evaluation of ecological risk.
Methodology
We made the assumption that ecological risk exists when ecological threat impairs the ability of
an ecoregion to perform basic ecological functions. This approach to risk evaluation was taken
because we recognized there is more to an ecosystem than aquatic or terrestrial organism
production and that impacts to all basic ecological functions need to be examined to fully
evaluate ecological risk. To identify basic ecosystem functions we made a brief review of the
ecological literature and revised a list of basic ecological functions identified by Rodale (1972)
and Southwick (1976), selecting those functions that related to the non-human environment
The list of basic ecosystem functions that we identified and that could be impaired by the
twenty-two problems (or stressors) includes:
1. distribution of water, minerals, and nutrients via the hydrologic cycle;
2. oxygen production and carbon dioxide consumption;
3. filtering and detoxifying of pollutants.
4. soil production and maintenance; and
5. production of aquatic organisms;
6. production of terrestrial organisms;
7. conversion of energy (sunlight) into organic matter;
With a listing of basic problems and a listing of basic ecosystem functions, we chose to evaluate
ecological risk for each ecoregion, by evaluating the impact of each problem on each ecological
function.
We began our work with the development of a model. The variables included in the model
represented variables common to all 22 problem areas: area of impact and degree of impact A
variable was also included to represent the differences from one ecoregion to another to
withstand environmental stress, degree of vulnerability.
After conceptualization of the model we then proceeded to obtain information from the
appropriate programs on area and degree of impact for each problem. Upon receipt of the
-------
data the information was reviewed and quality controlled to ensure that appropriate values were
entered into the computer for calculation of ecological risk index values. The degree of
vulnerability values were taken from established data that could be obtained on endangered
species, soil erosion rates, primary productivity, stream density and assimilative capacity. With
data input complete, an ecological risk index value was generated for each problem per
ecoregion and for the five state area.
When data for the majority of the 22 problems had been obtained, entered, and risk indices
derived, it was possible to rank or estimate the ecological risk posed by each of the problems
(Table 1).
Results and Discussion
Category 1 problems are those which were found throughout most ecoregions and in many
situations impacted over one-third of the individual ecoregions. In addition, the impact from
these problems is significant for it usually involves elimination of vegetative, aquatic and
terrestrial populations with associated reductions in natural assimilative capacity and increased
soil erosion. The magnitude of these impacts cannot be underestimated for large rates of
conversion of land to agricultural land exceeds 30,000 acres per year in some states in our
Region which in turn is then subjected to the application of fertilizers, pesticides, and
herbicides.
Category 2 problems to some extent are an outgrowth of Category 1 problems. For example,
non-point source stress would be expected to be great in areas with high rates of pesticide
application, increasing agricultural production and high rates of urbanization. The
hazardous/toxic air pollution problem ranks high because of the large number of facilities
discharging chemicals to this media in Region 6 (over 1300). Most of these facilities are not
currently regulated by sufficient standards.
Category 3 problems represent a mixture of problems which are limited in scope, from 5 to 20
percent of the individual ecoregions. In general these problem areas have some established
standards or State/Federal programs to control the emission.
Category 4 problems represent problems of limited area with effective control or responsive
programs in place which help to reduce the residual risk.
Of particular concern are problems which go beyond the scale of ecoregion impacts and which
are not ranked at this level Such problems include stratospheric ozone depletion and global
wanning. The research in those areas indicates that climatic changes over the next century will
result in increased temperatures. These problems should be of particular concern to in this
Region because:
1. we have a large number of air toxic dischargers in Region 6 which may contribute
significantly to the global problems;
2. we have a high percentage of the nation's coastal wetland resources which could be lost
due to temperature increase and the associated sea level rise;
3. stratospheric ozone depletion and the resultant increase in UV-B radiation could erode
-------
the foundation of the marine food web (marine organism larvae and phytoplankton) again
impacting on the Regions wetlands;
4. and, the basic factors which determine ecoregion boundaries in our Region are primarily
determined by climate, change in the climate causing shifting of these boundaries would
have devastating consequences.
The risk associated with climatic change appears to be very high with lasting damage to the
environment.

-------
Conclusions
The lack of an established methodology for evaluating ecological risk led the ecological risk
workgroup to develop a mathematical model to assist in the ranking process. The model's
variables were common to all problem areas and represented each ecoregions ability to
withstand stress.
We found databases difficult to obtain, due to ongoing work responsibilities of workgroup
members and Regional staff. Databases were obtained from within EPA, state and other
federal agency sources. The data submitted frequently consisted of estimates due to time
limitations and the regulatory nature of the information source (data was not usually gathered
with risk research as its primary use). Nevertheless, we were able to complete a relative
ranking of risk that sorted problem areas on the basis of area, degree of impact and degree of
vulnerability of these areas of impact.
Aside from global warming, the problems of greatest ecological risk in Region 6 appear to stem
from agriculture and silviculture. The conversion of forested wetlands and uplands to
agricultural land or monoculture pine forests and subsequent application of pesticides and
herbicides also results in non-point source water quality concerns. Of additional importance is
the unregulated discharge of toxic air pollutants which may play a long term role in global
warming and stratospheric ozone depletion.

H. INTRODUCTION
The Region 6 Comparative Risk Project began in April, 1990. The ecological workgroup was
formed with representatives from various program offices with an expertise or knowledge of
ecological functions and values. Our deadline for completion of this project was originally
September 1990, however, the schedule was extended to November 1990. Communication with
work group members was made by memorandum and telephone communications on at least a
bi-weekly basis. At the beginning of our analysis, weekly meetings were in order, but when
specific assignments were made meetings were reduced to once a month.
1. The intent and purpose of our analysis was to evaluate 22 environmental problem areas
and relatively rank them on the basis of residual ecological risk.
2. We developed a mathematical model. We initially reviewed the methodologies for
evaluating ecological risk utilized by Regions 1, 3 and 10 and then proceeded to develop a
more quantitative approach.
3. We also chose to evaluate risk at the ecoregion level (Omernik 1986; Map 1) because:
a) it was geographically and ecologically based;
b) the ecoregions could serve as a template for data collection;
c) this approach lended itself well to geographic information system applications;
d) there are a wide variety of ecoregions within our five state region (portions of
twenty-five ecoregions);
e) we were concerned about the general health of the large ecological units recognizable
in the landscape; and
f) there was a short time frame to complete our initial evaluation of ecological risk.

HI. APPROACH AND METHODS
Initial Approach to Risk Evaluation
We made the assumption that ecological risk exists when ecological threat impairs the ability of
an ecoregion to perform basic ecological functions. This approach to risk evaluation was taken
because we recognized there is more to an ecosystem than aquatic or terrestrial organism
production and that impacts to all basic ecosystem functions needed to be examined to fully
evaluate ecological risk.
To identify basic ecosystem functions we made a brief review of the ecological literature and
reviewed a list of basic ecological functions identified by Rodale (1972) and Southwick (1976),
selecting those functions that related to the non-human environment The list of basic
ecosystem functions that we identified and that could be impaired by the twenty-two problems
(or stressors) includes:
a) distribution of water, minerals, and nutrients via the hydrologic cycle;
b) oxygen production and carbon dioxide consumption;
c) filtering and detoxifying of pollutants;
d) soil production and maintenance;
e) production of aquatic organisms;
f) production of terrestrial organisms; and,
g) conversion of energy (sunlight) into organic matter.
With a listing of basic problems and a listing of basic ecosystem functions, we chose to evaluate
ecological risk for each ecoregion, by evaluating the impact of each problem on each ecosystem
function (Figure 1). To determine generally which stressors or problems would impact which
functions we developed a simple evaluation matrix plotting problems or stressors on the x-axis
and ecological functions on the y-axis (Figure 1). We then proceeded to discuss as a
workgroup whether or not each problem would generally have an impact on each function and
recorded an impact as an X in the matrix or an O if there was no anticipated impact (Figure
1). During our workgroup discussions it became apparent that there was a wide range of
variability associated with the impacts of the various problems on any given function. We then
realized that a numeric ranking system might be very useful in assisting us as we evaluated the
impacts of each problem on each function and ranked the various problems. We wanted to
replace the X's on our preliminary evaluation matrix (Figure 1) with a numeric value. An
evaluation matrix with numeric values could be completed for each ecoregion.
Development of the Conceptual Model
Prior to formulation of a mathematical expression that would assist us in replacing our X's with
numeric values, we had to take a closer look at the problems and the functions. We reviewed
the range of problems to be evaluated and found twenty problems that were primarily chemical
discharges and two problems that dealt with physical modification of the environment (Table 2).
It was also apparent that the physical modifiers frequently would have a greater impact than the
chemical discharges upon ecological functions (aquatic organism production, soil production,
terrestrial organism production, etc). Furthermore, the range of the chemical discharges was
incredibly diverse and impacted the environment through all media; soil, water and air. The
result of this problem analysis was the realization that we would have to identify variables
common to all of the diverse problems, but could still vary from one problem to the next.

After a brief period of analysis, we identified at least two characteristics common to all of the
problems, which could be measured or quantified. These variables were:
a) area of impact and
b) degree of impact.
Each of the twenty-two problems has an area of impact that can be measured or estimated for
each ecoregion, and each of the problems has a degree of impact upon the environment which
was recognizable (from a chronic impact, to an acute impact, to permanent elimination of
ecological function on a particular site). The ecological threat can be expressed as a
mathematical function of the area of impact and the degree of impact
11
-------
The mathematical function can be written as follows:
BT = f(AI>DI)
where;
EJ = ecological threat of each problem upon each function within a particular
ecoregion,
AI = area of impact of each problem within a particular ecoregion.
Dj = degree of impact of each problem upon each function within a particular
ecoregion.
Our initial analysis of each problem's impact upon each ecological function was incomplete; for
our conceptual model did not allow for variation in the ability of each ecoregion, to withstand
the impact of the various problems. We know that each ecoregion has unique characteristics
that allow it to be more or less vulnerable that other ecoregions (whether it be more
endangered species, more erosive soils, low stream flows, low photosynthetic rates, etc). In
effect, each ecoregion has its own unique ability to bounce back (or not bounce back) when it
is impacted by each of the twenty-two problems. Consequently, the same impact (in terms of
area and degree of impact) may have a much more devastating effect upon the environment in
one ecoregion than in another, simply due to the characteristics of the ecoregion. We revised
our conceptual model to include a variable for each ecoregion that reflects it's vulnerability to
the problems. We call this variable, degree of vulnerability (Dy).
By including an ecoregion's degree of vulnerability (Dy) in our evaluation we are no longer just
considering ecological threat (Aj and Dj); we are now dealing with a type of risk (ecological
threat applied to the degree of vulnerability of an ecoregion). This risk can be expressed as an
indicator number (or index) as shown below:
ERI = f (A,, D,, Dy)
where;
ERI = index of ecological risk, posed by the ecological threat of a specific
problem to a specific ecological function.
Aj = area of impact of each problem, within a particular ecoregion.
D] = degree of impact of each problem upon each function with a particular
ecoregion.
Dy = degree of vulnerability of each function within each ecoregion.
12
-------
Formulation of the Model
Identification of Variables
The variables that we have identified as being common to all twenty-two problems are area of
impact and degree of impact In addition, we recognized that each ecoregion had inherent
characteristics that determined its individual vulnerability to each of the twenty-two problems.
In other words, to evaluate ecological risk we are concerned with the three variables: area of
impact (Aj); degree of impact (D|); and degree of vulnerability (Dy), and how they interact.
Behavior of the Mathematical Expression
We are not developing a causal model that predicts explicitly how an individual ecosystem
would react to a specific stressor. Rather, we need a mathematical expression that will assist us
in ranking the relative ecological risk associated with each of the twenty-two problems in each
ecoregion. The mathematical expression should incorporate the previously identified variables
(Aj, Dj and Dv) and behave in manner that will facilitate ranking. Specifically, we would want
the ecological risk index (ERI) to:
a. increase as the area of impact increases
b. increase as the degree of impact increases
c. increase as the degree of vulnerability increases
Initial Formulation of the Mathematical Model
A formulation that achieves these objectives may be written as follows:
ERI = Aj/ A£ . Dj . Dy
where;
ERI = ecological risk index (reflecting that it is just an indicator of risk)
Aj = area of impact by each problem per ecoregion
AE = area of ecoregion
Dj = degree of impact of each problem on each function in each ecoregion
Dy = degree of vulnerability of each function in each ecoregion
Refinement of the Mathematical Model
To further refine the mathematical model, we applied it to a theoretical ecoregion to determine
what modifications were needed. Refer to Figure 2 to facilitate review.
13

ECOREGION X
Figure 2: Degrees of Impact and Degrees of Vulnerability in a Theoretical Ecoregion.
-------
The example we have chosen deals with the impact of hazardous air pollutants on terrestrial
organism production. Within the ecoregion, there are areas of vulnerability that reflect counties
containing endangered species (Dv3), counties containing species of special concern (Dv2), and
counties with common species (Dvl). Within each of these areas of vulnerability, there can be
areas with varying degrees of impact [none (DIo), chronic (Djj), acute (D^), and elimination
(DI3)]. (In our particular case, we have chosen to have three degrees of vulnerability and four
degrees of impact, however, the number of degrees is theoretically unlimited). The area of
greatest risk should be where the problem is eliminating habitat or populations (DI3) in areas
with endangered species (Dv3); while the area of least risk is where there is a chronic threat
(DI1) to populations or habitat of common species (Dvl). In addition, if there is no discharge
of air pollutant (DIo), there should be no risk, regardless of the area of vulnerability.
Within each area of vulnerability, there is the possibility of four degrees of impact from the
hazardous air pollutant problem (Dj0, DII( Dj2, and DI3). To determine the total risk to a
single vulnerability area it is necessary to sum across the degrees of impact. Expressed
mathematically as follows:
n-1
ERIV = Z Aii/AE • DII • Dv
i=0
where;
ERIV = ecological risk posed by all levels of air pollutant discharge within a single
vulnerability area
n = number of degrees of impact (four in this case)
Aji = sum of area of impact for all discharges with an impact of i (in this case i
is 0, 1, 2, 3)
AE = area of ecoregion
DJJ = degree of impact (varies with AJJ, 0, 1,2, 3)
Dv = degree of vulnerability
To determine total risk for the ecoregion, it is also necessary to sum across all areas of
vulnerability (Dvl, Dv2, Dv3). The revised model to accommodate variability in degrees of
impact for each problem, and variability in degrees of vulnerability for each function, can be
expressed mathematically as depicted in Figure 3.

IV. DATA ACQUISITION
After identification of needed input variables,(A/, D/ and Dy),it was necessary to obtain
information from each of the twenty-two program areas which regulated each of the problems
of concern. Specifically, we needed to obtain information on the areas of impact for each
problem within each ecoregion and information on which sites or facilities were of greatest
concern and why. This was accomplished by formally requesting information from the
appropriate program offices (Attachment C).
In most cases it took from one to several months to receive a response from each of the
program offices due to competing priorities and limited availability of data. The information
received from the programs consisted of area measurements, area estimates, number of facility
estimates, estimates on zones of impact, information on program specific ranking systems and
general information on which facilities or sites were of greatest concern to individual programs.
These program reports varied greatly in quality, extent of information and were based in many
cases on very broad assumptions and very limited data bases. When the program reports were
received, they were catalogued and placed in a file for safe keeping.
As the program reports were received, they were assigned to a work group member for review
and evaluation. As part of the evaluation process each work group member extracted the
necessary area of impact information (Attachment D) and extent of impact information from
each report. The area of impact (D;) information was entered directly onto a data input form
(Figure 4) and the extent of impact information was used to assign a degree of impact value
using the method described in Attachment E. The degree of impact values were entered onto
the data input forms. Values for the degree of vulnerability (Dv) were determined for each
ecoregion using the methodology described in Attachment F. The appropriate vulnerability
values for each ecoregion were also entered onto the data input forms.
As data input forms for each problem were completed the data were entered into a computer
for calculation of ecological risk indices for each problem (Attachment G contains additional
discussion of data management).

V. RESULTS
Ecological Risk Posed By Each Problem
The ecological risk index values for each problem are displayed in a tabular manner as shown in
Tables 3-17. Note that in each table, risk index values are presented by function for each
ecoregion and that a total risk index value for each ecoregion is displayed in the right hand
column of each table. The value at the bottom of the right hand column of each table
represents the residual risk posed by that problem across the five state region. Thus, the
aggregate residual risk index for industrial point source discharges to surface waters is 5.31
(Table 3).
Note that there are zero values listed under the oxygen production and carbon dioxide
consumption function on all of the Tables ( 3-17). There are zero values in this column
because we have been unable to decide how to evaluate this function separate from the primary
production function. Nevertheless, the work group recognized oxygen production and carbon
dioxide consumption as a valuable but distinct ecological function and have chosen to leave it in
the matrix for further consideration at a later date. As the matrix tables are examined, the
reader will note that there are frequently zero values throughout the hydrology and soil
production columns and occasionally zero values throughout other columns as well. The
uniform zero values are present when the work group did not believe that a specific problem
would normally have an impact upon a specific function (refer to Figure 1).
Working across each matrix table, a value in a column simply indicates that function is at risk in
that ecoregion due to the problem described at the top of the page. The magnitude of the risk
index value is the value derived from utilizing the risk index equation (Figure 3). The area of
impact values, degree of impact values, and vulnerability values that were used to calculate the
risk index values for each problem, are included in Attachment H.
Ranking Of Residual Ecological Risk
When the ecological risk index value for each problem is taken from the bottom of Tables 3-
17 and ranked in an ordinal manner the result is that depicted in Table 18. Note that the
range of risk index values varies from Application of Pesticides with a value of 81.90 to
Airborne Lead with a value of 0.01.
Distribution Of Residual Ecological Risk Per Problem
The information contained in Tables 3-17 can be readily mapped to visually display the
distribution of residual risk posed by each problem. The range of values in the right hand
column of each table represents the range in residual risk posed by the problem identified at
the top of each table. Each value in the in the right hand column correlates with an ecoregion
identified in the left hand column of each table.
To visually portray the distribution of risk for each problem, the range of values in the right
hand column was determined and divided by four. This identified four categories of residual
risk. A fifth category representing no known residual risk was also added. A color sequence
19
-------
was then identified for each of the five categories of risk. Shades of blue were used to depict
relative levels of risk within each water problem. Shades of pink and red were used to depict
relative levels of residual risk within each air problem. Shades of green to yellow were used to
depict relative levels of residual risk caused by physical degradation problems. Shades of purple
and lavender were used to depict relative levels of residual risk caused by waste problems.
Shades of orange to red were used to depict relative levels of residual risk caused by the
application of pesticides.
The visual depiction of residual risk posed by each environmental problem is shown in Maps 2-
16.
Residual Ecological Risk Per Ecoregion
Ecological risk index values for problems within each ecoregion are displayed in a tabular
manner as shown in Tables 19-40. In each table, risk index values are presented by function
for each problem and a total risk index value for each ecoregion is presented at the bottom of
the table. For example, the aggregated residual risk index for the Central Texas Plateau is 2.37
(Table 19). The range of risk index values varies form 2.37 to 40.61. As in the previous set of
tables (3-17), there are zero values listed under the oxygen production and carbon dioxide
consumption function. There are also zero values throughout the tables where problems are
not likely to impair ecological functions. A value in a column indicates that problem is present
in the ecoregion and that the problem has the potential to impair that ecological function. The
magnitude of the risk index value is derived from utilization of the risk index equation (Figure
3).
The values in the right hand column of each table represent the total ecological risk posed by
each problem in the ecoregion.
Distribution of Ecological Risk Per Ecoregion
When the input data for all thirteen sets of data (one for each problem) are combined, it is
possible to calculate the aggregate or cumulative ecological risk posed by all thirteen problems
to each ecoregion (Table 41). The risk index values are presented by function per ecoregion,
with the values in the right column representing the total residual ecological risk posed by all
the evaluated problems. The information from the right hand column can be visually portrayed
(Map 17) to show which ecoregions are at greatest residual risk and which ecoregions are at
least residual risk dtje to the cumulative impact of all evaluated problems.

VI. DISCUSSIONS
Discussion of Residual Ecological Risk Posed by Each Problem
Industrial Point Source Discharge to Surface Waters
The risk index information contained in Table 3 reflects information provided by the water
programs from each state's 305(b) report. Areas of impact are those stream segments in each
ecoregion that are not meeting water quality standards due, at least in part,to industrial point
source discharges. The ecoregions with the highest risk index values are those with the greatest
percentage of stream miles impaired by industrial point source discharges (Table 42).
Consequently, the Western Gulf Coastal Plains, the Mississippi Alluvial Plains, the Southeastern
Plains and Central Irregular Plains of Oklahoma have the highest risk index values, which is
visually portrayed by Map 2.
POTW Discharges to Surface Waters
Like the industrial point source problem, the information contained in Table 4 reflects
information contained in the states 305(b) reports. Areas of impact are those stream segments
in each ecoregion that are not meeting water quality standards due, at least in part, to POTW
discharges to surface water. The ecoregions with the highest risk index values are those with
the greatest percentage of stream miles impaired by POTW discharges (Table 42). As a result,
the Western Gulf Coastal Plain, Southeastern Plains, East Central Texas Plains, and Texas
Blackland Prairies are the ecoregions at greatest risk due to POTW discharges, which is visually
depicted in Map 3.
Non-Point Source Discharges to Surface Waters
Like the aforementioned water problems, the information obtained in Table 5 reflects
information obtained in the states 305(b) reports. Areas of impact are those stream segments
in each ecoregion that are not meeting water quality standards due, at least in part, .to non-
point source problems. Unlike the aforementioned problems, ecoregions with the highest risk
index values are not those with the greatest percentage of stream miles impacted, although they
are close to the top of the list. The ecoregions with the greatest risk index values are the
Southern Rockies and Arizona/New Mexico Plateau which is visually portrayed by Map 4. This
ranking appears to be due not only to percentages of stream miles (Table 42) impacted but also
due to the vulnerability of the ecoregions (Table 44).
Physical/Degradation of Water and Wetlands
The information contained in Table 6 reflects information extracted from Fish and Wildlife
Service (FWS) reports. Area of impact is the estimated remaining acerage of wetlands per
ecoregion. In some cases it is not possible to locate information on an ecoregion basis.
Specifically it was not possible to discern acerage amounts in the Southeastern Plains and
Mississippi Valley Loess Plains. This is unfortunate because both ecoregions are known to
contain extensive acerage of wetlands. Excluding these two areas, the ecoregions with the
greatest risk index values are the Western Gulf Coastal Plain and Mississippi Alluvial Plain
93
-------
(Map 5). These high values reflect the high percentage of these ecoregions remaining in
wetland acreage (approximately twenty percent).
RCRA Hazardous Waste Sites
The values in the matrix (Table 7) reflect information provided by the RCRA program. The
distribution of 389 RCRA facilities was plotted on an ecoregion map by program personnel and
provided to the workgroup. Those ecoregions with the greatest number of facilities have the
greatest risk index values. The Western Gulf coastal Plains (with over one third of all RCRA
facilities), the Texas Blackland Prairies, the Central Irregular Plains and the Mississippi Valley
Loess Plain all ranked high due to the large number of facilities. This is visually portrayed in
Map 6.
CERCLA Hazardous Waste Sites
The risk index information in Table 8 contains risk index values for fourteen ecoregions, each
of which contains at least one CERCLA site. Information was provided by the program on
actual size of each site plus an estimated off-site zone of impact of one mile in radius around
each facility. Those ecoregions with the highest risk index values were those with the greatest
percentage of ecoregion impacted (Table 42). However, the high vulnerability of the central
Irregular Plains also contributed to its high ranking (Table 44). The distribution of residual
risk from CERCLA sites across the region is visually depicted on Map 7.
Accidental Releases
The accidental releases category included essentially any contaminants accidentally released into
the environment during transport or production. The distribution of residual risk from accidental
releases occurs in most ecoregions within EPA Region 6 (Map 8). Information was provided by
the program which described the average size of each spill site and the frequency of
occurrences by county. We projected impacts based upon a 50-year period. The ecoregions
with the highest risk index values were the Mississippi Valley Loess Plain of Louisiana, the
Western Gulf Coastal Plain of Texas and the Central Irregular Plains of Oklahoma (Table 9).
Application of Pesticides
The application of pesticides and herbicides occurs across most ecoregions but it is particularly
widespread in the Mississippi Alluvial Plain, Western High Plains, Central Great Plains and
Central Irregular Plains of Oklahoma. High percentages of these areas are in agricultural
production. Consequently, they have high risk index values (Table 10). The distribution of
residual risk for application of pesticides across the region is shown by Map 9.
Ozone and Carbon Monoxide
These discharges were only considered problems when there were non-attainment areas for
ozone or carbon monoxide. There were non-attainment areas for these pollutants in ten
ecoregions as shown in Table 11 and depicted on Map 10. The Western Gulf Coastal Plain,
Mississippi Valley Loess Plains, and Texas Blackland Prairies have the highest risk index values
primarily due to higher percentages of area impacted (Table 42).
94
-------
Airborne Lead
The discharge of airborne lead as it is currently defined, is restricted to those immediate areas
around lead smelters. There are only four such smelters in the five state area and they are
located in two ecoregions (Table 12) the Texas Blackland Prairie and Mississippi Valley Alluvial
Plain. Consequently, Map 11 only depicts two ecoregions where airborne lead may pose an
ecological risk.
Particulate Matter
Discharges of particulate matter are only considered to pose ecological risk if non-attainment
areas are present. Only three ecoregions contain non-attainment zones including the
Arizona/New Mexico Plateau, the Southern Deserts and Western High Plains. Again, the risk
index values (Table 13) appear to be significantly determined by the percentage of ecoregion
that is impacted (Table 42). Map 12 portrays the geographic distribution of ecological risk per
ecoregion due to particulate matter.
Toxic Air Pollutants
The discharge of toxic air pollutants occurs at some locations within most ecoregions.
Consequently, there are risk index values for all but four ecoregions (Table 14). Those
ecoregions which appear to be of greatest ecological risk include the Central Irregular Plains of
Oklahoma, the Western Gulf Coastal Plains, the Texas Blackland Prairies and the Mississippi
Valley Loess Plains (Map 13). These areas have high risk index values due to the potential to
impact large areas of each of these ecoregions.
Physical Degradation of Terrestrial Ecosystems
The definition of physical degradation of terrestrial ecosystems did not specify the activities to
be considered in evaluating the scope of this problem. To a great extent, the activities we
considered only included those that we could locate some type of databases within the time
allowed to complete the project. Consequently, we evaluated the potential impacts associated
with agriculture (plowing and harvesting), silviculture (harvesting), and urbanization. We were
unable to consider additional problems including metals mining, uranium mining, grazing and
highway construction due to limitations in the databases. (However, there are discussions
addressing highway construction and grazing impacts on a statewide basis in the physical
degradation report provided by the program).
Evaluation of the risk posed by physical degradation requires review of three risk matrix tables
(Tables 15-17) and three distribution maps (Maps 14 - 16). The agriculture matrix (Table 17)
and Map 16 indicate the highest potential environmental risk due to plowing and harvesting is
in the Central Oklahoma/Texas Plains, Mississippi Alluvial Plain and Central Irregular Plains.
The silviculture practices of clearcutting and conversion of lands to pine monoculture has a
significant impact on the environment. The risk posed by those activities tends to be centered
where timber production is the greatest in the South Central Plains, Boston Mountains, and
Ouachita Mountains (Table 15 and Map 14).
95
-------
Urbanization is also pervasive (Table 16) but it appears to be greatest in the Texas Blackland
Prairies along the Interstate Highway 35 corridor which includes the cities of Austin, Dallas, Ft.
Worth and San Antonio (Map 15).
Discussion of Ranking of Environmental Problems by Ecological Risk Index Values
The ranking of problems depicted in Table 18 is determined to a great extent by the magnitude
of the potential area of impact for each problem. This is apparent when the ordinal ranking in
Table 18 is compared to the total areas of impact for each problem in Table 43. Specifically,
the problems with the greatest areas of impact (application of pesticides, toxic air pollutants and
physical degradation of terrestrial systems) rank high, while those with low areas of impact rank
low. However, the degree of impact for specific problems (Table 45) also modifies the ordinal
ranking. This is apparent when the area of impact for application of pesticides is compared
with the area of impact for air toxic discharges (Table 43). Both of these problems potentially
impact up to 42 million acres within the five state area and both are widespread across the
Region, impacting nearly all ecoregions. However, the risk index value for application of
pesticides is nearly double the risk index value for toxic air pollutants. This difference in risk
index values appears to be due primarily to the difference in degree of impact values (Table
45). The total degree of impact value for air toxics is five while the total degree of impact
value for- application of pesticides is eight or nine (Table 45).
Overall it appears that the ordinal ranking is influenced most by area of impact, followed by
degree of impact values and then degree of vulnerability values. This is due to the range in
values, for each of these variables. The total area of impact values range from 12,000 acres
(for airborne lead) to over 42 million acres (for toxic air pollutants), a difference in magnitude
of approximately 3,500. This is modified by the area of ecoregion, which reduces the range
from 0.01 percent of the Region impacted (for airborne lead) to greater than 11 percent of the
Region (air toxics), a factor of approximately 1100. The total degree of impact values range
only from 3 to 29 (Table 45), a factor of approximately 10. The total degree of vulnerability
values range from 10 to 23 (Table 44), a factor of only 2.3. The result is that the range in risk
index values between problems is primarily determined by area but it is modified by degree of
impact and degree of vulnerability.
Discussion of Residual Ecological Risk Per Ecoregion
When all of the individual problems are viewed collectively (Table 41 and Map 17), the risk
index values are greatest for the Mississippi Alluvial Plain, Western Gulf Coastal Plains, South
Central Plains, Texas Blackland Prairies, and Central Irregular Plains of Oklahoma.
Each of these ecoregions has high risk index values because they are impacted by a variety of
problems. The Central Irregular Plains are subject to ecological risk because of particulate
matter releases, application of pesticides, CERCLA hazardous waste sites, industrial point
source discharges, RCRA hazardous waste sites, toxic air pollutants and physical degradation
caused by agriculture. This ecoregion is also vulnerable because of the relatively high number
of terrestrial endangered species per county.
96
-------
The Western Gulf Coastal Plains has a high aggregate risk index value due to POTW
discharges, RCRA waste sites, toxic air pollutants, ozone and carbon monoxide releases,
industrial point source discharges and physical degradation of wetlands.
The Mississippi Alluvial Plain has a high risk index value due to particulate matter releases,
physical degradation of wetlands, application of pesticides, industrial point source discharges and
physical degradation of terrestrial systems due to agriculture and silviculture practices. This
area also has a high vulnerability value for soil erosion.
The South Central Plains has a high aggregate risk index value due to physical degradation of
terrestrial systems caused by silviculture and agriculture, physical degradation of wetlands,
particulate releases and numerous moderate values for other problems. This area also has a
high vulnerability value for soil erosion.
The Texas Blackland Prairies has a high ecological risk index value due to airborne lead, ozone
discharges, toxic air pollutants, physical degradation of terrestrial systems caused by urbanization,
RCRA hazardous waste sites, POTW discharges and numerous moderate values for other
problems.
Discussion of Problems Not Evaluated by the Risk Index Methodology
It was not possible to evaluate two problems at this time using the risk index methodology
because of limited information on estimated areas of impact per ecoregion. These problems are
other ground water contamination and underground storage tanks. The underground storage
tank program provided the workgroup with an estimate of 21,400 leaking tanks in the Region,
each with an estimated zone of impact of approximately one surface acre. The problem is how
to distribute these estimated zones of impact per ecoregion. Until more site specific
information can be obtained from State or local data sources, it will not be possible to evaluate
this problem using the current risk index method. Nevertheless, it is possible to estimate the
ranking by comparing total estimated area of impact with other programs which have been
ranked (Table 43). The 21,400 total acreage value appears to place the underground storage
tank problem within ranking of the problems with the lowest level of residual risk. This is
evident when the total areas of impact for other low ranking problems are reviewed.
Specifically, airborne lead has an estimated cumulative impact zone of 12,000 acres, particulate
matter has an estimated cumulative impact zone of 311,000 acres and CERCLA waste sites has
an estimated cumulative impact zone of 151,000 acres. Since leaking underground storage tanks
are not likely to have a greater degree of impact than CERCLA sites, ranking the underground
storage tank problem below the CERCLA problem is reasonable.
The ground water contamination problem differs from the underground storage tank problem,
for the program was not able to identify specific sites of contaminated groundwater that were
causing a problem to non-human populations. However, the program did provide the
workgroup with a report that identified areas where groundwater contamination, as currently
defined, could impact non-human populations. The areas of potential impact are the areas with
Karst geology, the Central Texas (Edwards) Plateau and the Ozark Highlands. The problem
which prevents utilization of the risk index methodology is narrowing the zone of impact to
97
-------
areas which represent a realistic scope of the problem. This can likely be accomplished through
accessing State and local databases. In terms of ranking this problem by category, it is not
possible at this time. However, it is likely to fall into the lower half of the ordinal ranking
when the data is eventually obtained.
Two other problems are not evaluated using the risk index methodology, primarily due to
shortages of manpower. Comprehensive data sets were provided by the programs for other
municipal waste-sites and other industrial waste-sites. Unfortunately, the workgroup member
initially assigned to review and evaluate the material was unable to do so due to demanding
program related assignments. The task was reassigned to two other individuals but they were
also unable to complete the necessary data review due to demands placed upon the individuals
by their programs.
Finally, the task of reviewing the data was undertaken by a fourth individual who was not able
to complete the data review and evaluation in time to be included in this report Throughout
this project all workgroup members were frequently placed in situations of competing priorities.
In all of these situations, the comparative risk project had to take a back seat to program
related responsibilities. It is only due to the dedicated efforts of the workgroup members that
nearly all problems were fully evaluated.

Discussion of Concerns Relative to Databases
A review of Table 43 points to areas of concern relative to potential problems with
existing databases.
With regard to physical degradation of water and wetlands, it is interesting to note that
no acreage values have been provided or estimated, for the Southern Rockies, Flint
Hills, Southeastern Plains or Mississippi Valley Loess Plain. One would expect a small
acreage of wetlands in the Flint Hills and Southern Rockies. It is known that extensive
wetland acreage exists in the Southeastern Plains and Mississippi Valley Loess Plain.
The wetland risk index map and matrix reflect these inherent biases.
Another data set which should be viewed with some degree of caution, relates to
application of pesticides. Again, no estimated or reported values were available for the
Southeastern Plains, Mississippi Valley Loess Plain, Flint Hills and Southern Rockies.
In addition, no values were reported for the Arizona/New Mexico Plateau, Arizona/New
Mexico Mountains and Boston Mountains. Many of these areas have limited acreages
in plowed agricultural land but concern exists primarily in the Southeastern Plains,
Mississippi Valley Loess Plain and Flint Hills, where some agricultural activities are
known to exist.
As a result of the aforementioned issues, the risk posed by the twenty-two problems
may not be accurately reflected in this analysis. The risk to the Southeastern Plains is
probably greater than that indicated by the composite ranking (Table 41).
Furthermore, the limited risk posed to the Flint Hills appears to merit further
investigation. The databases utilized indicate there is no risk to the Flint Hills as the
problems are currently defined.
Another concern relates to the water discharge problems. The information used to
evaluate the POTW, industrial and non-point source problems dealt only with impacts
to streams not lakes or reservoirs. Data is available in the State 305 (b) reports on
lakes, which are having water quality problems. However, we did not have acreage
values available for lake acreage per ecoregion. Consequently, impacts to lakes were
not evaluated as part of the ranking exercise. When this analysis is conducted, the risk
index values may increase for POTW, industrial and non-point source problems.
Discussion of Geographic Areas Which Were Not Evaluated
There are a several geographic areas which were not evaluated by this analysis,
including: near coastal waters, the continental shelf, deep waters of the Gulf and
problems of global scale.
Of particular concern are problems which go beyond the scale of ecoregion impacts
113
-------
which are not ranked at the ecoregion level. Such problems include stratospheric
ozone depletion and global warming. The research in those areas indicates that
climatic changes over the next century will result in increased temperatures. These
problems should be of particular concern to this Region because:
1. we have a large number of air toxic discharges in Region 6 which may
contribute significantly to global atmospheric problems;
2. we have a high percentage of the nation's coastal wetland resources which
could be lost due to temperature increase and the associated sea level rise;
3. stratospheric ozone depletion and the resultant increase in Ultraviolet
radiation could erode the foundation of the marine food web (marine
organism larvae and phytoplankton) again impacting on the Regions wetlands;
4.. and, the basic factors which determine ecoregion boundaries in our Region
are primarily determined by climate, changes in climate causing shifting of
these boundaries would have devastating consequences.
The risk associated with climatic change appears to be very high with lasting damage to
the environment.
Uncertainty
In order to complete the objective of relative ranking of the residual risk posed by the
twenty-two problems defined by EPA Headquarters, many assumptions were made.
Some assumptions were made because an established methodology for evaluating
ecological risk has yet to be developed, others were made because data was not readily
available. It soon became apparent that the best we could do was document our path
and record assumptions along the way because there was uncertainty at every step. To
some extent the methodology utilized was contingent upon the availability of data, time
and manpower. It is within these constraints that this report and its products were
developed.
In this section of the report we intend to review and discuss some of the major
assumptions that were made in order to complete this project. The types of
assumptions fall into several categories: method assumptions, model assumptions and
data assumptions. We have attempted to inventory our major assumptions and they
are detailed in Tables 46-49. The following sections discuss the basic major
assumptions and their implications in greater detail.
Method Assumptions
Our first major decision was to determine at what level to evaluate ecological risk.
Regions 1, 3 and 10 chose to evaluate risk at the ecosystem level in their evaluations
114
-------
but it seemed to some of us on the workgroup that the ecoregion might be a more
appropriate initial evaluation level. We believed that we could obtain databases on
specific ecoregions, and we could locate them on a map. At this point in time we do
not know the geographic location of all the ecosystems/communities that lie within each
ecoregion nor do we have much ecosystem specific data.
Our basic assumption is that ecological risk exists when ecological stress (posed by any
one of the twenty-two problems) impairs the ability of an ecoregion to perform basic
ecological functions. There are innumerable alternative routes that could have been
taken including selecting specific chemicals and specific indicator or keystone species as
receptors, then evaluating the impact of each chemical discharge upon each indicator
species. This approach holds a great deal of promise, but we could not agree upon
which chemicals to select or which species to select. In addition, this approach can not
evaluate risk caused by physical degradation of wetlands or physical degradation of
terrestrial ecosystems. Furthermore, such an approach appears to be more oriented to
evaluation of populations and communities, not large landscape units.
We made the decision to evaluate impact on a functional scale. One could argue that
fewer or more ecological functions should be addressed, we would agree with the
reader. Consequently, we leave it to future workgroups to refine or modify the current
functional evaluation approach.
To assist in our ranking of stressors, we eventually identified variables that were
common to all twenty-two problems, which would vary from one problem to the next
and could be measured or estimated. These variables were area of impact and degree
of impact. We also added the variable, degree of vulnerability, to account for
differences in sensitivity from one ecoregion to the next. Other variables could
definitely be considered including intensity, reversibility, and duration. To an extent
these variables are already incorporated in the degree of impact and degree of
vulnerability variables but inclusion as separate variables appears to hold a great deal
of merit for future investigation.
Model Assumptions
We combined the variables in a mathematical model depicted in Figure 3, creating in
the process, a set of underlying assumptions, including:
1) As the area of impact increases, the level of ecological risk increases.
2) As the degree of impact increases (intensity and duration of impact) the level
of risk increases.
3) As the degree of vulnerability increases, the level of ecological risk increases.
These assumptions appear to be consistent with the recent report published by EPA's
Science Advisory Board (1990), however, we question whether risk should always
increase in a linear manner.
Other broad assumptions underlying our approach include those identified in Table 47.
As indicated in Table 47, many of these assumptions were made due to limitations in
115
-------
availability of time, manpower, and databases. These assumptions can be relaxed in
future years as the databases become available.
Area of Impact Assumptions
Table 48 contains an inventory of assumptions that were made in the process of
identifying the area of impact for each problem evaluated. The assumptions are
arranged by problem with a brief explanation of why the assumption was made. Of
particular interest is the variation in assumed potential zones of impact for some
problems. Specifically, RCRA sites are assumed to have potential impact within a
three mile radius of a site, CERCLA sites are assumed to have a potential impact
within a one mile radius of the site, airborne lead is assumed to have a potential
impact within a two kilometer radius of a site, and toxic air pollutants are assumed to
have an impact within a four mile radius of a site. These assumptions were provided
by each program. We question why this variation in zones of impact exists from one
program to the next. Review of the assumptions also indicates that the risk index
values we have generated reflect maximum potential zones of impact because we did
not have the site specific data readily available from the programs. As the specific
data is obtained on actual zones of impact, we would expect residual risk for RCRA
sites, airborne lead, CERCLA sites, and toxic air pollutants to be reduced.
Vulnerability Assumptions
Assumptions were made when vulnerability values where developed for each ecoregion.
The assumptions relate to development of environmental indicators of vulnerability and
to assumptions underlying the ranking system. These assumptions are detailed in Table
49. Note that the assumptions are listed along with some information on why the
assumptions were made. As was the case with the area assumptions, many of them
were made because data was not readily available. In future years, some of the these
assumptions can be relaxed as data becomes available.

Table 46 Method Assumptions
Assumptions
1) Residual ecological risk can be evaluated at the ecoregion level.
2) Ecological risk exists at an ecoregion level, when ecological stress (posed by
environmental problems), impairs the ability of an ecoregion to perform basic
ecological functions.
3) Ecological risk at an ecoregion level can be estimated by evaluating potential
impacts to the following ecological functions.
a) distribution of water, minerals and nutrients via the hydrologic cycle;
b) oxygen production and carbon dioxide consumption;
c) filtering and detoxifying of pollutants;
d) soil production and maintenance;
e) production of aquatic organisms;
f) production of terrestrial organisms; and
g) conversion of energy (sunlight) into organic matter;
4) Residual risk to each function can be estimated by measuring or
approximating area of impact of each problem, degrees of impact to each
function and degree of vulnerability for each function.

vn. CONCLUSIONS
Process
Our most important product was development of an interactive process to evaluate and
communicate the residual ecological risk, posed by a variety of physical and chemical
environmental problems, at a regional level. The process requires documentation of decision-
making by explicitly describing the risk evaluation technique (a mathematical model),
enumeration of assumptions and keeping track of data sources. The real value of the process is
that it can be modified, and it is repeatable. The risk evaluation approach can continue to be
improved through improvement in databases, improvement in the evaluation technique
(mathematical model), and removal of broad-based assumptions.
To complete our initial ranking of the residual risk posed by the twenty-two problems provided
by EPA Headquarters, we took the following sequence of steps:
1) We evaluated residual ecological risk at ecoregion level;
2) We made the assumption that ecological risk exists when ecological stress (posed by
any one of the twenty-two problems) impairs the ability of an ecoregion to perform
basic ecological functions. The list of basic ecological functions that we identified that
could be impaired includes:
a) distribution of water, minerals and nutrients via the hydrologic cycle,
b) oxygen production and carbon dioxide consumption,
c) filtering and detoxifying of pollutants,
d) soil production and maintenance, ;
e) production of aquatic organisms,
f) production of terrestrial organisms, and
g) conversion of energy (sunlight) into organic matter via photosynthesis.
3) With a listing of basic problems and a listing of basic ecosystem functions, we chose to
evaluate ecological risk for each ecoregion by evaluating the impact of each problem
on each ecological function.
4) We evaluated the impact of each problem on each function by using a mathematical
model, that combined the variables area of impact, degree of impact and degree of
vulnerability to generate a risk index value.
5) By using existing databases, creating new databases, and making assumptions, we
estimated the distribution of each problem by ecoregion in the five state area, and
generated risk index values for each problem per ecoregion. In this manner, we
identified those ecoregions which were at greatest risk and identified the distribution of
each problem. These results were then visually depicted using maps generated by the
Region's geographic information system.
6) By combining risk index values across all functions for each problem, we were able to
generate thirteen risk index values which could be used to rank the problems in a
relative manner.
129
-------
Experience in using the previously described process lead us to the following conclusions:
1) A mathematical index is useful in evaluating and ranking relative levels of residual
ecological risk.
2) A geographic information system (GIS) is useful in communicating residual ecological
risk, from large arrays of data, generated by a mathematical index system.
3) We were able to use a GIS to convey some of our results because we utilized a
mathematical index and because we chose to evaluate risk at the ecoregion level (i.e.
we knew the geographic location of the ecological units).
Ranking of Environmental Problems
On the basis of area of impact, degree of impact and vulnerability of each ecoregion (as
previously defined), we were able to rank the residual risk posed by the environmental problems
from one to thirteen. However, due to the variation in databases and nature of some of our
assumptions, we feel more comfortable with grouping the problems into categories as depicted
in Table 50.
Category 1 problems - physical degradation of terrestrial systems, physical degradation of
wetlands and pesticide application, are those problems which were found throughout many
ecoregions and in many situations could impact over one-third of individual ecoregions. The
impact also tends to be significant, for these problems usually eliminate vegetative, aquatic and
terrestrial populations with associated reductions in natural assimilative capacity and increased
soil erosion. The magnitude of these impacts cannot be underestimated, for silviculture alone,
is responsible for the conversion of 30,000 acres of lands to pine monoculture per year within
areas in our Region. The acreage estimates associated with these problems tends to be much
more reliable than other problems evaluated.
The Category 2 problems - non-point source discharges and toxic air pollutant discharges, to
some extent, are an outgrowth of Category 1 problems. For example, non-point source stress
would be expected to be great in areas with high rates of agriculture, pesticide application and
urbanization. The hazardous toxic air pollution problem ranks high because of the large
number of facilities discharging chemicals to this media in Region 6 (over 1300) and because it
is assumed that each facility can impact over a 50 square mile area. The Category 2 problems
tended to have an ecological risk index (ERI) value of 30 to 50. We believe that the risk for
toxic air pollutants may decrease as site specific information becomes available. We also believe
that the risk index for non-point source problems will increase as the States' non-point source
assessments continue to improve. In general Category 2 problems are not regulated by existing
standards or programs, and databases do not clearly define zones of impact
Category 3 problems represent a mixture of problems which are limited in scope with ERI
values in the range of 5 to 20. The areas of impact associated with these problems tend to be
less than ten to twenty percent of individual ecoregions. In general, these problem areas have
some established standards or State/Federal programs to control the emissions.

131
-------
Category 4 problems represent problems of limited area or problems responsive programs in
place which help to reduce the residual risk.
It is important to note that the ecological ranking is relative not absolute. Furthermore, we do
not intend to convey that environmental damage is always occurring. We are simply indicating
that on the basis of vulnerability of an ecoregion, estimated area of impact and relative
magnitude of impact, residual risk exists and category 1 problems tend to pose the greatest
threat to ecoregions in Region 6. The remaining categories tend to pose relatively lesser levels
of risk for the aforementioned reasons.
Conclusions that can be drawn from our ranking of the twenty-two problems defined by EPA
Headquarters are as follows:
1) The problems-physical degradation of wetlands, physical degradation of
terrestrial systems and application of pesticides-individually pose the
greatest residual risk to ecoregions in Region 6.
2) The problems-non-point source discharges and toxic air pollutants-
individually pose the second highest level of residual risk to ecoregions in
Region 6.
3) The problems-discharges of carbon monoxide and ozone, discharges from
POTWs.discharges from RCRA sites, industrial discharges to surface
waters, groundwater contamination, discharges from municipal and
industrial sites, and accidental releases-individually pose a lower level of
risk to ecoregions in Region 6.
4) The discharges-airborne lead, releases of particulate matter, discharges
from CERCLA hazardous waste sites and discharges from underground
storage tanks-individually pose the lowest level of risk to ecoregions in
Region 6.
Problems Per Ecoregions
In addition to ranking the residual risk posed by each of the twenty-two problems, we identified
which problems posed the greatest risk to each individual ecoregion. The ecoregions which
were at greatest risk due to the aggregate risk of thirteen problems include:
a) the Central Irregular Plains of Oklahoma,
b) the Mississippi Alluvial Plain,
c) the Texas Blackland Prairies, and
d) the Western Gulf Coastal Plain.
Those ecoregions which were at lowest risk due to the aggregate risk of thirteen problems ,
were:
a) the Central Texas Plateau,
b) the Southern Deserts,
c) the Arizona/New Mexico Mountains, and
d) the Southern Texas Plains.
132
-------
In ecoregions faced with the greatest risk, the risk appears to be predominately caused by
physical degradation of terrestrial systems, physical degradation of wetlands, hazardous air
pollutants and application of pesticides. In those ecoregions faced with the least risk, the
majority of residual risk appears to be caused by application of pesticides and non-point source
discharges to surface waters.
133

VIII. RECOMMENDATIONS
Recommendations of National Implication
1. To fully evaluate ecological risk we recommend that techniques be developed to assess,
evaluate and communicate ecological risk at several levels, including:
a) the site specific and/or population specific scale,
b) the community and/or ecosystem specific scale,
c) the ecoregion scale, and
d) the biospheric or global scale.
In this manner specific discharges or activities can be fully evaluated, for specific
discharges or activities may not only have site specific impacts but also contribute to
ecosystem, regional and global impacts. Cumulative impact evaluation should not be
overlooked, nor should impacts which occur to abiotic components of the environment.
Risk evaluation techniques should be developed and refined for both chemical discharges
and physical modification. Methods for combining and evaluating these diverse problems
should also be developed. Once appropriate techniques have been developed, they can
then be selected for usage on the basis of the objective of the risk assessment or
evaluation.
2. To facilitate development of the aforementioned techniques we recommend a meeting in
the near future that brings together personnel from each Region, that have developed
each Region's comparative risk evaluation techniques. The purpose of such a meeting
would be to compare and discuss each Region's methodology and to develop better
approaches to evaluate comparative ecological risk. This workgroup of regional and
headquarters personnel should also define the term comparative ecological risk.
3. A method for economic analysis of environmental risk assessment should be developed
in conjunction with the development of an ecological methodology. This could enable
managers to directly correlate environmental costs versus environmental benefits through
marginal analysis or break-even analysis. Marginal analysis results could then be directly
applied and used to justify program disinvestment and investments during the strategic
planning process.
4. We recommend that our approach or a similar modified approach be used at a national
level to evaluate comparative ecological risk. Specifically, we recommend:
a) utilization of a mathematical index to evaluate and rank residual
ecological risk,
b) initial evaluation on an ecoregion scale to determine how relative risk is
distributed across the country.and
c) utilization of a geographic information system, to generate maps which
effectively communicate the distribution of residual ecological risk
nationwide.
135
-------
5. In using our approach or a modified approach, on a national level we further
recommend that:
a) ecological functions be weighted for relative ecological importance; and
b) ecoregions be weighted for their importance at an interregional or
national scale (for instance some regions of the country may have high
concentrations of endangered or threatened species or be important to
migrating populations).
6. We recommend that Regions continue to evaluate comparative residual risk at an
ecoregion level but work to acquire databases so specific ecosystems can be identified
and located geographically. After adequate databases have been acquired, we
recommend evaluation at the ecosystem or community level. An intermediate level of
evaluation may exist at a sub-ecoregion level based on vegetative cover type.
7. We recommend that all Federal natural resource agencies at the Headquarters level
pool their resources to share existing natural resource databases and to identify the
location of communities and ecosystems across the country.
8. After comparative ecological risk techniques (recommendation 1) and econometric
resource evaluation techniques (recommendation 3) are developed, we recommend that
all Federal natural resources agencies (EPA, USDA, USDI, NOAA, and the COE)
combine efforts to:
a) evaluate the ecological risk posed by each environmental problem that
each agency regulates;
b) identify programs across all natural resource agencies that could be
reduced in scope, increased in scope or combined with other programs;
and
c) redirect resources across agency boundaries (if necessary) to maximize
environmental risk reduction.
Recommendations for Future Comparative Risk Evaluations
1. Prior to undertaking the next ecological comparative risk project, at least one person
per two programs evaluated needs to be detailed for preparation of specific program
reports, obtaining needed databases, evaluating and interpreting data and report
preparation. Each individual should be detailed for 120 days. Contract support for
computer programming, map preparation and typing should also be available when the
risk evaluation effort begins.
2. The Region needs to seek input from state and local natural resource agencies in future
years, to access statewide and localized databases, and obtain their input
3. Databases for groundwater and storage tank problems should be further developed to
allow for future evaluation by the mathematical index methodology. Specifically, the
areas of impact for each of these problems to non-human populations needs to be
identified.
136
-------
4. The list of problems evaluated needs to be expanded to include oil and gas discharges,
water toxic discharges, mining, grazing, highway construction and litter.
5. The impacts to aquatic and terrestrial organism production in the Western Gulf Coastal
Plain and Mississippi Alluvial Plain need to receive an increased weighing value. This is
necessary because these two ecoregions provide wintering habitat to large concentrations
of wildlife which spend major portions of their lives in other ecoregions. Consequently,
an impact in these two areas is likely to go beyond ecoregion boundaries.
6. Associated with recommendation 3 is the need to expand the definition of the
vulnerability indicators for terrestrial and aquatic organisms to include important
keystone or indicator species in addition to endangered species.
7. The mathematical model needs to be re-evaluated to determine whether separate
intensity and duration variables are needed. The model also needs to be evaluated to
determine whether a reversibility variable needs to be added, or used to replace the
vulnerability variable.
8. A decision needs to be made by the next workgroup to determine whether any of the
ecological functions should be weighted for purposes of calculating risk index values.
9. The location of unique biological areas or communities needs to be identified through
accessing of:
a) the National Wetland Inventory, and
b) the State heritage program databases.
If possible, these databases should be obtained in a digitized format and entered
into the Region's geographic information system.
10. Databases in each of the programs need to be collected or developed on an ecological
basis, whether it be by ecoregion or community type, for both aquatic and terrestrial
regions or communities.
General Recommendations
1. In past years the Council of Environmental Quality has produced Environmental Trends.
a national perspective of the state of the environment. Although the document gives us
insightful national trends, it is not specific enough to apply the findings to our agencies
programs or regional problems. We recommend that a regional "State of the
Environment" report be generated to continue to track the state of our regional
environment. This report may or may not be utilized in future ecological risk analysis.
2. Research is needed to identify indicator or keystone species. Research is also needed to
investigate the assimilative capabilities of various community types and study the impacts
of chemical discharges on whole communities. In this manner, we can preserve the
health of ecosystems as well as individual species.
137
-------
3. Ecological risk can be evaluated at the county level using the existing method by simply
changing the area of ecoregion to area of county (\) and inputing data for the other
variables as currently defined. In this scenario, a matrix score sheet needs to be
developed for each county instead of one for each ecoregion. The area of impact will
also only reflect area of impact within each county not each ecoregion.
4. Ecological, risk management and health risk values can be combined in future
mathematical index models, if desired to create a combined risk index ranking.
5. The risk associated with specific chemicals can also be evaluated and portrayed
graphically, through modification of the existing methodology.
6. Results from this risk evaluation can be used for targeting agency enforcement,
permitting and grant activities.
7. Large - scale problems, such as pesticides, physical degradation of water and wetlands
physical degradation of terrestrial ecosystems, non-point source and groundwater
contamination need to be addressed comprehensively through sustainable agriculture
initiatives or studies.

Revised Core List of Environmental Problem
Areas for Regional Comparative Risk Projects
Problem Areas
1. Industrial Wastewater Discharges to Oceans, Lakes, and Rivers
These are sources of pollution that discharge effluents into surface waters through discrete
conveyances such as pipes or outfalls.This problem area does not include publicly and privately
owned municipal wastewater discharges. Pollutants of concern include total suspended solids;
BOD, toxic organics, including pthalates and phenols; toxic inorganics such as heavy metals; and
thermal pollution. Typical sources of discharge include metal finishing, pulp and paper
processing, and iron and steel production. Facilities requiring permits under the National
Pollution Discharges Elimination System (NPDES) fall under this problem area.
2. Municipal Wastewater Discharges to Oceans, Lakes, and Rivers
This problem area includes all constituents of the outfalls of publicly and privately owned
treatment facilities. Both municipal sewage treatment outfalls and industrial discharges that flow
through publicly operated treatment works are included in this problem area. Major
contaminants include all those found under Industrial Wastewater Discharges to Oceans, Lakes
and Rivers, plus ammonia, chlorination products, and nutrients. Combined Sewer Overflows
(CSO's) are included in this problem area.
3. Aggregated Public and Private Drinking Water Supplies
As drinking water arrives at the tap, it may contain a wide variety of contaminants from both
natural and man-made sources, and point and non-point sources. Since many of the
contaminants can be traced to other problem areas, Drinking Water risk evaluation will involve
much double-counting with those other problem areas (Industrial Wastewater Discharges,
POTW Discharges, Non-point Source Discharges, Storage Tanks, hazardous and non-hazardous
waste problem areas, etc.). Drinking Water is included as a problem area because
remediation/treatment options can occur either at the source of contamination (the other
problem areas) or at the delivery system of the drinking water (treatment or switch to
alternative supplies). Drinking Water includes both delivery systems that serve 25 or more
people and are therefore covered by the Safe Drinking Water Act, and those which serve fewer
than 25 people and are not so covered. Pollutants of concern include disinfection byproducts,
pesticides, inorganics (such as heavy metals), radionuclides, toxic organics, fluoride from natural
sources, and microbiological contaminants.
4. Non-point Source Discharges to Oceans, Lakes, and Rivers
Non-print Source Discharges include pollutants that reach surface waters through sources other
than discrete conveyances for effluents. This includes runoff from agricultural, urban, industrial,
silvicultural, or undisturbed land. Possible pollutants are quite varied, although they include
most of constituents of the point source discharges to surface waters.
A-l
-------
Storm water carries a large amount of solids, nutrients, and toxics. Other sources included in
this problem area are surface discharge of septic tanks, contaminated in-place sediments, air
deposition of pollutants (except for acids), and mine drainage. Pollutants not included in this
problem area are acid deposition, solid waste disposal, hazardous waste sites (RCRA &
CERCLA), pesticide runoff, and physical impacts from discharges of dredge and fill material.
5. Physical Degradation of Water and Wetland Habitats
Damages arising from alterations in the quantity and flow patterns of ground water and surface
water are included in this problem area. Such disturbances include channelization, dam
construction and operation, surface and ground water withdrawals, construction and flood
control, irrigation distribution works, urban development, and the disposal and runoff of dredge
and Gil materials. Physical changes to water flow and aquatic habitats are included in this
problem area, as is chemical contamination resulting from physical changes (e.g. dredging of
contaminated sediments).
6. Aggregated Ground-Water Contamination
All forms of ground water pollution, including sources not counted in other problem areas,
compose this problem area. These include fertilizer leaching, septic systems, road salt, all
injection wells, nonwaste material stockpiles, pipelines, irrigation practices. The list of possible
contaminants is extensive and includes nutrients, toxic inorganics and organics, oil and
petroleum products, and microbes. As with drinking water, there is much double-counting in
this problem area. It is included as a separate "special" problem area like drinking water
because a true understanding of the overall risks to this resource is particularly important, and
because such an understanding is difficult if the risks re split between many different problem
areas.
7. Storage Tanks
Storage Tanks includes routine or chronic releases of petroleum products or other chemicals
from tanks that are above, on or underground, tanks owned by fanners, fuel oil tanks of
homeowners, or other storage units (such as barrels).
Stored products include motor fuels, heating oils, solvents and lubricants that have air emissions
or can contaminate soil and ground-water with such toxics as benzene, toluene, and xylene.
This category excludes hazardous waste tanks. Acute releases (explosions, tanks collapse) are
examined under Accidental releases.
8. RCRA Hazardous Waste
This category generally includes the risks posed by active and inactive hazardous waste sites
regulated under the Resource Conservation and Recovery Act (RCRA). These sites include
RCRA open and closed landfills and surface impoundments, hazardous waste storage tanks,
hazardous waste burned in boilers and furnaces, hazardous waste incinerators, and associated
solid waste management units. See page and routine releases from these sources contaminate
soil, surface water, groundwater, and pollute the air. Contamination resulting from waste
A-2
-------
transportation and current illegal disposal are also included. Radiation from hazardous "mixed
waste" from RCRA facilities included in this problem area.
9. Hazardous Waste Sites ~ Abaodoned/Superfund Sites
This category includes hazardous waste sites not covered by RCRA, but by Superfund. Most
are inactive and abandoned. Sites can be on the National Priority List (NFL), deleted from the
NFL, candidates for the NPL, or simply be noted by the federal government or states as
unmanaged locations containing hazardous waste. Sites may contaminate ground or surface
water, pollute the air, or directly expose humans and wildlife. There are many pollutants and
mixtures of pollutants, including TCE, toluene, heavy metals, and PCB's. Radiation from
hazardous "mixed waste" in abandoned/Superfund sites is included in this problem area.
10. Municipal Solid Waste Sites
Municipal waste sites includes open and closed municipal landfills, municipal sludge and refuse
incinerators, and municipal surface impoundments. These sources can contaminate ground and
surface water and pollute the air with particulates, toxics, BOD, microbes, PCDFs, PBB's, and
nutrients. Contamination may occur through routine releases, soil migration or runoff. Most
sites are regulated under Subtitle D. This category excludes active and inactive hazardous waste
sites.
11. Industrial Solid Waste Sites
Industrial waste sites includes open and closed industrial landfills, industrial sludge and refuse
incinerators, and industrial surface impoundments. These sources can contaminate ground and
surface water and pollute the air with particulates, toxics, BOD, microbes, PCDFs, PBB's, and
nutrients.
Contamination may occur through routine releases, soil migration or runoff. Most sites are
regulated under Subtitle D. This category excludes active and inactive hazardous waste sites.
Although the list of potential contaminants is similar to municipal sob'd waste sites, the
concentrations, volumes, and mixes of pollutants found on typical sites are frequently very
different.
12. Accident Chemical Releases to the Environment
Contaminants are accidentally released into the environment in a variety of ways during
transport or production. An industrial unit may explode and emit toxics into the air, a railroad
tank car may turn over and spill toxics into surface water or roads, or a ship may run aground
and spill oil or other cargo into the environment. Damages to property, personnel, and wildlife
may occur from intense, short term releases of toxic or flammable chemicals. Acids, PCB's,
ammonia, pesticides, sodium hydroxide, and various petroleum products have been accidentally
released.
A-3
-------
13. Pesticides
This problem area addresses risks arising from the application, runoff, and residues of pesticides
to humans and the environment. It includes risks to people applying agricultural pesticides,
including farm workers who mix, load, and apply them. Also included are risks to the public
and non-target plants and wildlife as a result of short range drift, overspray, and misuse. Some
of the more dangerous substances include ethyl parathion, paraquat, dinoseb, EPN, aldicarb, and
diazinon. Disposal of mixed pesticide wastes has resulted in the generation of highly toxic,
largely unknown byproducts that have entered the air and caused serious health problems.
Suburban spraying of property, often done with high pressure systems, can result in
contamination of neighboring property, residents, pets, and livestock. Aside from direct
exposure, additional pesticide risks stem from exposure through ingestion of residues on foods
eaten by humans and wildlife. Bioaccumulation and food chain effects are also included in this
category. Note that accidental released, groundwater contamination, and indoor air pollution
from pesticides are respectively included in Accidental Releases, Aggregated ground water, and
Indoor Air problem areas.
14. Sulfur Oxides and Nitrogen Oxides (including Acid Deposition)
Sulfur Oxides and Nitrogen oxides cause a wide variety of primary and secondary effects.
Primary effects include health, visibility, and welfare impacts. A major secondary effect is acid
deposition, which results from chemical transformation of oxides of sulfur and nitrogen,
producing acid rain, snow, and fog, as well as dry deposition. Acid deposition alters the
chemistry of affected aquatic and terrestrial ecosystems, damaging plant and animal life.
Sources are a wide variety of industrial, commercial, and residential fuel and related combustion
sources. This problem also includes visibility effects resulting from the long range transport of
sulfates.
15. Ozone and Carbon Monoxide
Ozone and carbon Monoxide are major air pollutants in many areas, arising from both mobile
and stationary sources. Damage to forests, crops, and human health can be severe. Note that
volatile organic compounds (VOC's) are critical precursors to ozone formation, but the direct
effects of VOG's are included in the Air Toxics problem area. To the extent that VOC's result
in ozone, those ozone effects are captured by this problem area.
16. Airborne Lead
Air emissions of lead result from many industrial and commercial processes. This problem area
includes both direct exposure to airborne lead and exposure to deposited lead from airborne
sources. It does not include exposure to lead from drinking water delivery systems, or lead
found in homes and buildings from leaded paint
A-4
-------
17. Particulate Matter
Both total suspended participates and fine particulates/PM 10 are included in this problem area.
Major sources include motor vehicles, residential fuel burning, industrial and commercial
processes, and in some cases strip or open pit mining.
18. Hazardous/Toxic Air Pollutants
This problem area covers outdoor exposure to airborne hazardous air pollutants from routine or
continuous emissions form point and non-point sources. Pollutants include asbestos, various
toxic metal (e.g., chromium, beryllium), organic gases (benzene, chlorinated solvents), polycyclic
aromatic hydrocarbons (PAHs, such as benzo(a)pyrene, primarily in paniculate form), gasoline
vapors, incomplete combustion products, airborne pathogens, cooling towers, and a variety of
other volatile organic chemicals and toxics.
The problem area covers exposure through both inhalation and air deposition of these
pollutants to land areas. Runoff of deposited pollutants to surface waters is addressed in Non-
point Sources. Major sources include large industrial facilities, motor vehicles, chemical plants,
commercial solvent users, and combustion sources. This category excludes, to the extent
possible, risks from pesticides, airborne lead, radioactive substances, chloroflourocarbons,
emissions from waste treatment, storage and disposal facilities; storage tanks, and indoor air
toxicants.
19. Indoor Air Pollutants Other Than Radon
This category applies to exposure to accumulated indoor air pollutants, except radon, primarily
from sources inside buildings and homes. These sources include unvented space heaters and
gas ranges, foam insulation, pesticides, tobacco smoke, asbestos, carbon dioxide, carbon
monoxide, nitrogen oxides, lead, pesticides, and numerous volatile organic chemicals such as
benzene and formaldehyde. Occupational exposures are included, as is inhalation of
contaminants volatilized from drinking water.
20. Indoor Radon
Radon is a radioactive gas produced by the decay of radium, which occurs naturally in almost
all soil and rock. Risks occur when radon migrates into buildings through cracks or other
openings in the foundation, water, or fuel pipes. The gas is trapped by dense building materials
and can accumulate to very high levels. When inhaled, radon decay products can cause lung
cancer. This category includes radon volatilized from domestic water use, and also includes
occupational exposures. The problem area does not include outdoor radon.
21. Radiation Other Then Radon
Exposure to ionizing and nonionizing radiation (beyond natural background) is included here.
Sources of radiation included in this category are: radio frequencies (also T.V. transmitters,
power lines, radar, microwave transmissions, and radiation from home appliances and wiring);
radiation from nuclear power operations; high-level radioactive waste (including spent reactor
A-5
-------
fuel) and low-level waste (including radiophannaceuticals and laboratory clothing form hospitals
involved in nuclear medicine, tools used in cleaning up contaminated areas, etc.); and residual
radioactivity (including the decommissioning of facilities such as laboratories and power plants
that use radioactive materials. Also included in this category are industrial processes such as
uranium mining and milling, and the mining of phospate.
Radiation resulting from nuclear accidents where radioactivity is released is included under
Accidental Releases. Medical exposures (X-rays, radiation therapy) and exposure from ozone
depletion are not included.
22. Physical Degradation of Terrestrial Ecosystems/Habitats
Sources affecting terrestrial ecosystems/habitats include both chemical and non-chemical stress
agents. Because chemical sources of degradation are addressed in other categories, this
category includes physical modifications (such as mining and highway construction) and other
sources of degradation (such as dumping of plastics and other litter) that affect terrestrial
ecosystems/habitats.
Effects on undisturbed lands/habitats that result from nearby degradation (habitat fragmentation,
migration path blockage) are also included in this problem area. EPA often has no regulatory
authority over sources of physical degradation, while in other cases it may be able to influence
them through the NEPA/EIS process.

CHARACTERIZATION OF ECOREGIONS IN EPA's REGION 6
This report is a summary description of 24 ecoregions found in EPA'S Region 6. The definition
of ecoregion follows Gallant et al. (1989) and the ecoregion names and boundaries follow Omernik
(1987). Alternate local names are sometimes listed in parentheses. An ecoregion is defined as "an
area (region) of relative homogeneity in ecological systems." Ecoregions were developed through
analysis of patterns of climate, physiography (physical geography), mineral availability, soils,
vegetation, and land use. Basic information on these parameters is given for each ecoregion.
Information on ecology and wildlife are included for some ecoregions. (Numbers following each
section indicate references)
21 Southern Rockies
This region consists of high mountains and tablelands. Mountaintops are above 10,000 feet, with
steep slopes in the higher elevations; lower elevations, about 5,000 feet, have rolling to irregular
terrain.
Average annual precipitation is 30-60 inches in the higher elevations, where it is cold and humid
to arid. The lower elevations are semiarid with 12-16 inches of precipitation. Soils are derived
from sedimentary and crystalline rocks.
The natural vegetation at mid-elevations (5,000-10,000 feet) is heavily forested with western spruce,
fir, Douglas-fir, pine, and southwestern spruce. Upper elevations (above 10,000 feet) have alpine
meadows (bentgrass, sedge, fescue, bluegrass). Lower elevations (less than 5,000 feet) are
vegetated with greasewood, saltbush, sagebrush, and grasses.
Land use at the upper elevations is mainly wildlife habitat and recreation; the middle elevations
include the same, plus mining and grazing; at lower elevations there is just grazing. (2,8)
22 Arizona/New Mexico Plateau
These are tablelands with considerable to very high relief, with flat to irregular plains with low
mountains. The climate is arid to semiarid with annual rainfall from less than 8 inches to 18
inches.
Important grasses include grama and galleta. Great Basin sagebrush, saltbush, greasewood are
dominant shrubs.
Land use is subhumid grassland, semiarid grazing land, and desert shrubland grazing land. There
is some irrigated agriculture producing grains and vegetables. (2,8)
B-l
-------
23 Arizona/ New Mexico Mountains
These are low to high mountains forested with pinyon pine, Douglas-fir, juniper, southwestern
spruce, fir, and Arizona pine. Land use is mainly forest and open woodland grazing. (8)
24 Southern Deserts (Trans-Pecosl
The Trans-Pecos is sparsely populated and has little water. The landscape is dominated by dry
plains (8-18 inches of rain per year) which are deserts or semi-deserts. Much of this ecoregion is
the northern portion of the Chihuahuan Desert which extends deep into Mexico.
The plains are broken by high hills (1,800 to 4,000 feet) and mountains. There are several
mountain ranges, such as the Davis and Chisos Mountains with peaks of 5,000 to 8,750 feet. They
are either volcanic in origin or fault-block, where the earth's crust has been pushed up. Rainfall
is 20 or more inches in the higher elevations.
The eastern part of this region is the Stockton Plateau (the western part of the Edwards Plateau,
from Ft. Stockton to the Devil's River). This area is a rough mesquite-juniper brushland of
moderate relief.
Soils have developed from outwash materials from the mountains and are varied in surface texture
and profile characteristics. Sites are typically stony hills, clay flats, sands, saline soils, gypsum flats,
rough stony mountains gravelly outwash and badlands.
The two major rivers of the region are the Pecos and the Rio Grande. Most tributaries are
intermittent and subject to flash flooding.
The dominant desert plants include tarbush, creosote, yuccas, agaves, acacia, and cactus. Desert
grasslands of grama and tobosa grass are interspersed throughout the shrub desert. In the moun-
tains woodlands consist of oaks, junipers, firs, and pines.
Large mammals found in the mountains are mule deer and mountain lions. Pronghorn (antelope)
graze and browse on grass and shrubs of the shortgrass plains between the mountains. Their
populations are recovering somewhat after near extirpation. Typical wildlife of the desert include
the kangaroo rat, kit fox, cactus wren, and roadrunner. The surprising diversity of the region is
illustrated by the number of species found in Big Bend National Park: 10 amphibians, 55 reptiles,
382 birds, and 75 mammals.
Land use is mainly recreation (e.g. Big Bend National Park) or desert shrubland grazing. Much
of the area has been overgrazed in the past and has become a creosote-shrub desert.

25 Western High Plains (Llano Estacado. Staked Plains')
The High Plains are smooth to irregular plains; flat, featureless, treeless. Elevation changes from
2,600 to 4,000 feet south to north. The eastern boundary is the Caprock Escarpment. It is only
a few hundred feet high, but it is a distinct boundary with canyons cutting back into the plain. The
most famous is Palo Duro Canyon. The south and west boundary is the Mescalero Escarpment.
The Canadian River Valley, cuts Ecoregion 25 into northern and southern parts.
There is very little natural surface water. Rainfall is 12-20 inches per year.
Soils are derived from Tertiary outwash deposits from the Rockies of New Mexico. Material
eroded from the Rocky Mountains washed down and was deposited, creating the region's subsoil,
which is a mixture of marl, chalk, gravel, and caliche (a hard, limestone-like material). The rich,
sandy loam topsoil was blown onto the plain by southwest winds, probably from the Pecos River
valley.
The native vegetation type was short-grass prairie, mainly grama and buffalo grass. Trees along
streams include cottonwood, soapberry, and hackberry. Except along creeks, there were no trees
until they were brought in by settlers.
Typical wildlife includes jackrabbits, cottontails, prairie dogs, and burrowing owls which live in old
prairie dog burrows. Prairie dogs have been poisoned for many years by ranchers and the
government and their numbers have been greatly reduced. This has caused the decline of the
black-footed ferret which was extirpated from the region in the 1920's. Wolves were also
eliminated, but the coyote has thrived, apparently replacing the wolf. Pronghorn are also found
on the high plains.
Playa lakes, ephemeral ponds ranging in size from less than an acre to hundreds of acres, are
important habitat for wintering and migrating waterfowl, sandhill cranes, and shorebirds. There are
over 23,000 Playa lakes in Ecoregions 25 and 26, mostly on the Texas High Plains.
Land use is principally grazing, irrigated agriculture, and dryland farming. Oats, corn, sorghum are
common crops. (3,8,940,12)
26 Southwestern Tablelands (western part of Rolling Plains')
The topography is mostly hilly, with moderate to considerable relief (50-100 feet). Elevations range
from 800 to 3,000 feet southeast to northwest. High plateaus may tower 1,000 feet over river
valleys. Most streams are intermittent, and drought is common. Rainfall is between 10-22 inches
per year. The main river in the region is the Canadian, whose watershed helps define the region
through New Mexico and the Texas Panhandle.
Soils are dry and receive little organic input. They vary from coarse sands (along terraces adjacent
to streams) to tight clays or red-bed clays. Soils are neutral to slightly calcareous.
Streams are high in gypsum (calcium sulfate) and salt. There are several chloride control projects
in the region to help make the water more palatable.
B-3
-------
Dominant native vegetation was a prairie of blue grama, buffalo grass, sandsage, bluestem prairie.
With overgrazing, mesquite has invaded and become a dominant. Other important woody species
are juniper and lotebush.
Land use: Most of the region is cattle grazing on subhumid to semiarid grassland and semiarid
grazing land. There is some irrigated cropland.
(2,7,8,9,10)
27 Central Great Plains (eastern part of Rolling Plains. Reddish Prairies^
These are irregular, gently rolling plains. An important geological feature is the "Red Beds", red
sedimentary rock of Permian origin (250 million years ago) that is the parent material for the red
clay that is characteristic of much of the region. This gives the streams their reddish color, in
particular the Red and Canadian Rivers and tributaries.
Rainfall is between 18 to 30 inches per year.
The native vegetation was bluestem, grama, and buffalo grass. Now large areas, especially around
San Angelo, are dominated by mesquite, lotebush, or juniper.
"The basic ecological change on the Rolling Plains [ecoregions 26 and 27] has been from buffalo
and grass to beef cattle and mesquite, but also to cotton and other crops,"(8). (6,7,8,9,10)
28 Flint Hills
These are low, open hills. Rainfall is 35-40 inches per year. The native cover type is bluestem
prairie (bluestem, panic, indiangrass). Land use is subhumid grassland and semiarid grazing land.
(3,8)
29 Central Oklahoma-Texas Plains (Cross Timbers and Prairies')
These are irregular plains, mostly rolling to hilly. Soils vary considerably from brown, neutral to
acid sandy or clay loam, to dark calcareous clays over limestone. Rainfall varies from 26 to 46
inches per year.
This area has diverse vegetation types. The western part is dominated by mesquite-lotebush
shrubland. The central part is a mixture of post oak woods and oak-mesquite-juniper woods. The
eastern part is dominated by bluestem-wintergrass prairie, liberally interspersed with oak-mesquite-
juniper woods. Most of the region is used for grazing, either pasture or woodland. The better
soils are in cropland which comprises a small percentage of the region. (4,7,8,10)
30 Central Texas Plateau (Hill Country, eastern part of Edwards Plateau")
These are tablelands with moderate relief, and plains with high hills. The major geological features
of this area are the Edwards Plateau and the Llano Uplift (Central Basin). The eastern and
southern boundary is the Balcones Escarpment. To the west, it grades into the Stockton Plateau
B-4
-------
brushland of Ecoregion 24.
The Edwards Plateau is a huge slab of limestone, rising 1,500 to 3,000 feet above sea level The
limestone is derived from ocean sediment laid down in Cretaceous time in a warm, shallow sea.
The Llano Uplift was uplifted by magma in the Precambrian Era that cooled to form granite and
other igneous rocks, which is parent material for the soil
The soil is very poor, thin and rocky. Soils are usually shallow with a wide range of surface tex-
tures. Rainfall varies from 20 to 32 inches per year.
Originally the area was mainly grassland. With overgrazing by livestock, woody plants invaded. It
is now a scrubby savannah with an overstory of juniper, oak, and mesquite and an understory of
Indiangrass, buffalograss, bluestems, and gramas.
Land Use is recreational (hunting, canoeing, hiking, camping) and grazing in the open woodlands,
and subhumid and semiarid grasslands. It has an excellent mixture of forage plants, and ranches
are often stocked with combinations of cattle, sheep, and goats. The region has some of the best
whitetail deer habitat in Texas, and deer leases and services supporting hunting are an important
part of the economy. (4,7,8,9,10,13)
31 South Texas Plains (South Texas')
These are smooth to irregular plains. The northern boundary is the Balcones Escarpment, and,
roughly, the Nueces River. Soils range from clays to sandy loams. A wide range of soil types
creates great differences in soil drainage and moisture-holding capacities. Typical range sites
include deep sands, hardlands, shallow ridges, bottomlands, alkali flats and mixed sandy land.
Rainfall varies from 20 to 26 inches per year.
This area originally supported a grassland-savannah (bluestem/live oak). Decades of overgrazing
has altered the plant community and now there is a severe brush problem caused by mesquite, post
oak, live oak, cactus, and acacia. This brushland makes poor grazing , but it does provide habitat
for deer, javelina, turkey, quail, coyotes, rabbits, roadrunners, lizards, and snakes. In a few parks
and refuges, the Rio Grande Valley east of Falcon Dam supports a remnant of a diverse, essentially
Mexican plant and wildlife community not found elsewhere in the U.S.
Most of the area is still range land (subhumid to semiarid grazing land), but considerable acreage
is cultivated with irrigation. For example, the Rio Grande Valley produces much of the nation's
citrus fruit and vegetables. In Zavala and Dimmit Counties, conditions are ideal for growing
spinach and the area has become a major producer of this vegetable.
(7,8,9,10)
32 Texas blackland prairies
These are irregular plains, gently rolling to nearly level, 300-800 feet above sea level. Rainfall is
between 32 and 40 inches.
B-5
-------
The parent materials of the soils are chalk, soft limestone, marl, clay, and shale that was formed
from sediment laid down in a shallow sea in the Cretaceous Period (70-135 million years ago).
Important formations include the Austin Chalk and the Taylor Marl
Soils are fairly uniform, dark, calcareous clays with some gray, acid sandy loams. They are mainly
vertisols, the shrink-swell clays that develop wide, deep cracks when dry. These are the soils
common in Dallas that cause foundation problems.
The native climax prairie vegetation included little bluestem, big bluestem, Indiangrass, switchgrass,
and sideoats grama.
Most of this fertile area is now under cultivation, though some ranches remain. (4,7,8,10,13,15,16)
33 East Central Texas Plains (Tost Oak Savannah1)
These are irregular plains, gently rolling to hilly. Elevations are 300-800 feet above sea level.
Rainfall varies between 26 and 44 inches (west to east).
Soils on the uplands are light colored, acid sandy loams or sands. Bottomland soils are light brown
to dark gray and acid, ranging in texture from sandy loams to clays. The parent material is
sedimentary rock derived from sand, silt, and clay of Quaternary and early Tertiary origin.
This is a transition zone between the true prairies and eastern forests, and is sometimes classified
in one or the other category. The cover types include post oak woods and an oak-grassland
mosaic. The overstory is mainly oak-hickory and the understory is composed of tall grasses such
as little bluestem, Indiangrass, switchgrass. There is evidence that the brush and tree densities
have increased tremendously from pre-settlement conditions.
Most of the area is used as native or improved pasture, but small farms are common. (4,7,8,10)
34 Western Gulf Coastal Plain
This includes the Gulf prairies and the coastal marshes, which are flat plains, with elevations from
sealevel to 150 feet. Rainfall varies between 26 and 56 inches per year.
Soils on the coastal marsh are acid sands, sandy loams and clays. The upland prairie soils tend to
be heavier textured acid clay or clay loams, although there are some sandy loams. In general, soils
have slowly permeable profiles. Typical range sites include blackland, sandy prairie, lowland flat,
coastal sands, salt meadow and salt marsh.
On the uplands, climax vegetation is a tall grass prairie or post oak savannah. Major grasses
include tall bunch grasses such as big bluestem, seacoast bluestem, Indiangrass, and eastern gramag-
rass. However trees and brush have invaded many areas especially mesquite, oaks, pricklypear,
and acacia. In the coastal wetlands, the fresh marsh is dominated by sedges, especially bulrushes
(Scirpus spp.), while the salt marshes are mostly cordgrasses (Spartina spp.) and saltgrass (Di-
stichlis). Brackish marshes are mixed.
B-6
-------
The coastal marsh is, in Texas, only a relatively narrow strip of less than a million acres of fresh
and salt marsh out of over 13 million acres of this ecoregion in Texas. Louisiana (Cameron
Parish) has an additional 648,000 acres of coastal marsh (80% of the parish). These wetlands are
critical for the diverse and still abundant, but now stressed, Gsh and wildlife of the region. Nearly
all the commercial and sport fish and shellfish of the Gulf of Mexico depend on the bays and
intertidal marshes for food and shelter for their early life stages. Wintering waterfowl must have
access to the dwindling fresh marshes to see them through until spring. A majority of the bird
species of eastern North America are represented at some season on the Texas coast, using either
the wetlands or upland prairies and woodlands for wintering grounds, breeding areas, or migratory
stopovers.
The land use is mostly cropland with some grazing land. Most of the marsh is grazed by cattle.
(4,7,8,9,10,11)
35 South Central Plains fPinev woods')
These are forested, irregular plains. The soil on the uplands are poorly consolidated, light colored
to dark gray sands or sandy loams. With rainfall from 44 to 56 inches per year, soils are moist,
but poor in nutrients, highly leached, and acid.
The underlying formations are Cretaceous-Eocene deposits (60 • 135 million years old). The
boundary with the Paleozoic Ouachitas (Ecoregion 36) to the north is sharp, steep enough to
create rapids or waterfalls-i.e. the fall line.
In the extensive bottomlands of Neches, Sabine, Red, and Ouachita River systems the soil is rich
alluvium of relatively recent origin (a few thousand years in the lower areas, up to 1 million years
on the higher terraces).
This basic cover type is a mixed pine-hardwood forest Several species of pines, oaks, and hickory
predominate. Forests of oak, tupelo-gum, and cypress cover the river bottoms.
The primary land use is still forest land, with pine the principal commercial product. Even-age pine
monoculture is the preferred method. Little commercial hardwood remains. Many areas have been
cleared for improved pasture. With high rainfall and fertilizer, cattle raising is profitable.
(1,3,4,7,8,9,10)
36 Ouachita Mountains
The general landscape is open high hills to open low mountains. They are essentially a series of
east-west ridges. The Ouachitas were formed by extensive folding and faulting (tilting and crack-
ing). They are very old, formed in the early to mid-Paleozoic (350 to 500 million years ago).
Elevations range from 300-2300 feet The southernmost part, the Athens Piedmont, is an uplifted
plateau, and is rolling to hilly (400-1000 feet high).
The soils are silty clay and silty loam. They are deep in the valleys, but very shallow and stony on
the ridges. The parent material is Paleozoic sandstone, shale, and chert
B-7
-------
The basic cover type is a mixed forest of oak, hickory, and pine. An oak, gum, cypress community
occurs in river bottoms.
The area is used for grazing and general fanning. There are also many recreational opportunities
for camping, hiking, and canoeing. (1,3,8)
37 Arkansas Valley
Although this region corresponds closely to the Arkansas River Valley, it is defined geologically
as the trough lying between the Ozarks (Boston Mountains) on the north and the Ouachitas on
the south. The landscape is mainly rolling hills, interspersed with narrow ridges. The valleys are
at 300-500 feet but the ridges rise 1,000-2,000 feet above them.
Surface rocks are mainly sandstone and shale, which is the parent material of the sandy, silty, and
clay loam soil.
The vegetation is shortleaf pine-hardwoods on the uplands and bottomland hardwoods on the lower
alluvial soils. The land use is cropland with pasture, woodland, and forest. (1,3,8)
38 Boston Mountains
These are low mountains considered to be the southern part of the Ozarks, but are somewhat
younger, formed in the late Paleozoic Era (300 million years ago). They are more severely eroded
and more rugged than the Ozarks (ecoregion 39). The general elevation ranges from 1,500 to
2,300 feet but local relief can exceed 1,500 feet. Sandstone is exposed on summits. Shale also
sometimes occurs at the surface. Soils are sandy loams and clay loams derived from sandstone,
siltstone, and shale.
The forests are upland hardwoods, but with more shortleaf pine than the rest of the Ozarks. The
only relatively level land is the valleys or the ridge tops which are remnants of the old plateau
surface.
Land use is mainly pasture, with some general farming. (1,7,23)
39 Ozark Highlands
The Ozarks are very old dating from the mid-Paleozoic Era, 350 to 500 million years ago. They
are plateaus, uplifted as a unit, with minor folding or faulting. The ruggedness developed over the
eons from erosion of its rushing streams. Elevation ranges from 500 to 1,500 feet The boundary
with the Arkansas Valley (Ecoregion 37) is sometimes a steep escarpment, sometimes a gentle
slope with no sharp change.
Limestone, dolomite, sandstone, shale, and chert comprise the main surface rocks. Soils are mainly
silty loam; they are deep in the valleys and flat areas, but very thin on the steeper slopes. The
parent material is mainly limestone.
B-8
-------
The region's primary vegetation is an upland oak-hickory forest.
Land use includes farming, grazing, orchards, vineyards, and forest. (1,8,11)
40 Central irregular plains
These are irregular plains, moderately uneven, with a succession of valley plains and moderately
rounded hills. This is the result of erosion on strata of alternating beds of harder (sandstone) and
softer (shale) rocks. Erosion has created broad valleys that have gentle west slopes and steep
eastern escarpments.
Soils are clay or loam, formed from material weathered from sandstone, limestone, and shale laid
down in lowlands and shallow seas of the Pennsylvanian Period (300 million years ago).
Quaternary (less than 2 million years old) alluvial sediment is extensive along streams.
The native vegetation is a mosaic of bluestem prairie (bluestem, panic, Indiangrass) and oak/hickory
woodland. Land use is cropland with grazing land. (8,18,19,20)
65 Southeastern Plains
These are smooth to irregular plains. The land form is gently sloping terraces leading down to
level floodplains, the largest of which is the Pearl River which has extensive bottomlands.
The soils are loamy and formed from either marine or fluvial deposits and are of Recent or
Pleistocene age. The main cover type is a southern mixed forest (beech, sweetgum, magnolia, pine,
oak, and hickory).
The area is a mosaic of cropland, pasture, woodland, and forest. (8,21)
73 Mississippi Alluvial Plain
The name describes this ecoregion well: it is dominated and defined by the lower Mississippi River
floodplain. However, it could be divided into two subregions, the coastal marshes and the inland
bottomland forests. Rainfall is 50-60 inches per year.
Marsh soils are high in organic matter and are very productive. The soils in the alluvial plain are
by definition derived from sediment deposited by the river. They are deep and flat, and of relatively
recent origin (a few thousand years in the lower areas, up to 1 million years on the higher
terraces). Sands and silts are deposited closer to the river while clays are deposited in the
backwater areas. They are rich and very productive, but subject to flooding.
The coastal marshes cover about 2 million acres of the lower tier of parishes (excluding Cameron
Parish, see ecoregion 34). They grade from salt marsh near the Gulf to fresh marsh further inland
across a belt 20 -50 miles wide. As in ecoregion 35, these wetlands provide the fish and wildlife
habitat that support coastal fisheries, wintering waterfowl, and other wildlife.
B-9
-------
In the wettest bottomlands, is the cypress, tupelo-gum swamp. On the higher "second bottoms" is
a periodically flooded hardwood forest of oaks, hickories, magnolias, sweetgum, and canebrakes.
Over half of the forested bottomlands in Louisiana and over 85% in Arkansas have been leveed,
drained, and cleared for agriculture. Soybeans are particularly suited to this area. (5,11)
74 Mississippi Valley Loess Plains
These are hilly, irregular plains. The soil is loamy, derived from loess, fine-grained, wind deposited
material. The average rainfall is 60 inches per year. The cover type is a mixed forest of oak,
hickory, and pine. The area is cropland with pasture, woodland, and forest. (14,15,22)
75 Southern Coastal Plain
The area is flat plains (10-50% covered by standing water) dominated by the Pearl River. The
cover types are a southern mixed forest (beech, sweetgum magnolia, pine and oak) and a southern
floodplain forest (oak, tupelo, baldcypress). The rainfall is 60 inches per year. (8,21)

Region 6 Ecological comparative Risk Workgroup (6E-FT)
TO: Program Offices
As a follow-up to the April 17, 1990 memorandum from Mr. Winkle
concerning the request for information from branches for the
regional risk project, ve need specific information to complete
our analysis of ecological risk. In order to complete our
analysis the following information is needed from your branch:
1. A listing of *CRA facilities within each state, by city and
county.
2. The actual size of each site, or an estimate of the average
size of each site.
3. The estimated area around each site that could be impacted
by the facility.
4. A determination of which sites are the most damaging to the
vegetation, fish and wildlife and why using your best
professional judgment. Any general maps or ranking
mechanisms you may have would also be very useful for our
review.
Please respond or provide this information to us by June 15,
1990. If you should have any questions I can be reached at
extension 5-2263. Thank you for your prompt attention to this
request.

Derivation of D, = Degree of Impact
The degree of impact variable represents the characteristics of each problem and its impact
To determine degree of impact the question is asked what is the general impact of each problem
on each ecological function? (Ecological functions include mechanisms for distributing water and
nutrients, oxygen production, filtering and detoxifying of pollutants, soil production, aquatic
organism production and terrestrial organism production). There are six generic relative levels of
impact from which to choose, as described below:
Level 1 • Problem (discharge or activity) causes violation of an environmental standard which
protects an ecological function. *
Level 2 - Problem (discharge or activity) causing observable impairment or exists at a
concentration known to impair the ecological function.
Level 3 - Problem (discharge or activity) causes elimination of ecological function but duration
of impact lasts less than Gve years.
Level 4- Problem (discharge or activity) causes elimination of ecological function and duration
of impact lasts greater than five years but less than fifty years.
Level 5 - Problem (discharge or activity) causes elimination of the ecological function and
duration of impact lasts greater than fifty years.
Level 6 - Problem (discharge or activity) causes elimination of the landscape or modification
of ecoregion boundaries.
* If no standards exist, then level 1 impact is assumed to exist because an acceptable level of
impact has not been defined.
Definition of each ecological function and specific evaluation criteria for determining the degree
of impact for each ecological function are described in the following narratives.
A. HYDROLOGY- The mechanism for distributing water and nutrients across the surface of
the landscape, deals only with surface and groundwater available to non-human populations
within an ecoregion.
Degree of Impact Criteria: 1 • Problem results in minor disruption in surface or
groundwater distribution system.
2 - Problem results in disruption of hydrologic system for
less than a year.
E-l
-------
3 - Problem results in temporary elimination (less than
five years) of portions of the surface or groundwater
distribution system.
4 - Problem results in temporary elimination (greater than
five years but less than fifty years) of portions of the
surface or groundwater distribution system.
5 - Problem results in elimination (for greater than fifty
years) of portions of the surface or groundwater
distribution system.
6 - Problem results in elimination of the landscape or
modification of the ecoregion boundaries.
B. OXYGEN PRODUCnON/CARBON DIOXIDE CONSUMPTION - The production of
oxygen and consumption of carbon dioxide by plants. Evaluation criteria have not been
developed for this function.
C. FILTERING/DETOXIFYING OF POLLUTANTS - The ability of the ecoregion to remove
or make harmless contaminants, excess nutrients, or paniculate matter from air, water or
soils. The assimilative capacity of an ecoregion is determined by soils, topography, micro-
organism populations, vegetative uptake, stream flow and wind velocities.
Degree of Impact Criteria: 1- Problem reduces assimilative capacity of natural system
through destruction of vegetation and micro-organism
populations.
2 - Problem exceeds the assimilative capacity of the natural
system for less than a year.

5 - Problem continually exceeds the assimilative capacity
of the natural system (for greater than fifty years).
D. SOIL PRODUCTION - This is the ability of an ecoregion to maintain a dynamic soil
environment In a healthy soil environment weathering of sediments/litbologies, growth
of soil macro- and micro-biota, and the degradation of organic material continue at a rate
where inputs are balanced against outputs. When soils are stressed by environmental
E-2
-------
effects, organic matter may be lost, biota is stressed or eliminated and weathering rates and
products are effected. A stressed soil will have a reduced capacity to produce normal soil
gases, and act as a filter against contamination of groundwater. Since the stressed soil also
has a reduced ability to remain in place and is subject to erosive forces, soil loss rate as
determined by the Soil Conservation Service's Universal Soil Loss Equation or Rainfall
Erosion Index are useful indicators of the health of the soil The indicator of impact to
soil production is soil erosion.
Degree of Impact Criteria: 1 - Problem could cause soil loss problem.
2 - Problem causes observable or measurable soil loss.

Derivation of Dv = Degree of Vulnerability
The degree of vulnerability variable represents the characteristics of each ecoregion, which allow
each ecoregion to react differently to the stress posed by each of the twenty two identified
problems. These characteristics, some for each of the seven functions collectively determine an
ecoregions vulnerability to any one problem. Features that make an ecoregion vulnerable include
the number of endangered species, stream density per ecoregion, the existing soil loss rate,
existing rates of primary productivity and physical characteristics that affect filtering and detoxifying
of pollutants. The following narrative descriptions further define the range of vulnerability for each
of the seven ecosystem functions: terrestrial organism production, aquatic organism production, soil
production, oxygen production, primary productivity, hydrology, and filtering and detoxifying of
pollutants. The range for purposes of assigning a numeric value varies from 1-5.
A. Degrees of Vulnerability for Hydrology
The hydrology function for each ecoregion is determined by the distribution of surface and
groundwater hydrology, which is available to non-human populations. Degrees of vulnerability may
be defined as follows:
1 - Ecoregion is characterized by a high stream density of >0.25 stream miles per square
mile of drainage area.
2 - Ecoregion is characterized by a stream density of 0.22 to 024 stream miles per square
mile of drainage area.
3 - Ecoregion is characterized by a moderate stream density of 0.19 to 0.21 stream miles
per square mile of drainage area.
4 - Ecoregion is characterized by a stream density of 0.14 to 0.17 stream miles per square
mile of drainage area.
5 - Ecoregion is characterized by a low stream density of 0.09 to 0.13 stream miles per
square mile of drainage area.
B. Degree of Vulnerability for Oxygen Production/Carbon Dioxide Consumption
Criteria for determining degrees of vulnerability for oxygen production and carbon dioxide
consumption have not been developed.
C. Degrees of Vulnerability for Filtering and Detoxifying of Pollutants.
The assimilative capacity function is routinely performed by vegetation, microorganisms, soil
complexes and dilution in various media. Each ecoregion possesses characteristics that
influence its ability to filter and detoxify pollutants. General descriptions of the degrees
F-l
-------
of vulnerability are as follows:
1 - Ecoregion characterized by a mean annual morning wind velocity of >7 meters per
second and high annual stream flows.
2 - Ecoregion characterized by a mean annual morning wind velocity of 6 to 7 meters per
second and moderate to high stream flows.
3 - Ecoregion characterized by a mean annual morning wind velocity of 5 to 6 meters per
second and moderate stream flows.
4 - Ecoregion characterized by a mean annual morning wind velocity of 4 to 5 meters per
second and low to moderate stream flows.
5 - Ecoregion characterized by a mean annual morning wind velocity of 3 to 4 meters per
second and low stream flows.
D. Degrees of Vulnerability for Soil Production
On a regional level, the rainfall erosion index is useful in identifying areas which are
susceptible to erosion. The degrees of vulnerability which we used are as follows:
1 - Ecoregion characterized by a rainfall erosion index of 0 to 100.
2 - Ecoregion characterized by a rainfall erosion index of > 100 to 200.
3 - Ecoregion characterized by a rainfall erosion index of > 200 to 300.
4 • Ecoregion characterized by a rainfall erosion index of > 300 to 400.
5 - Ecoregion characterized by a rainfall erosion index of > 400 to 500.
E. Degrees of Vulnerability for Aquatic Life Production.
The production of aquatic organism varies form one water body to the next and water
quality standards for aquatic organisms propagation varies from one state to the next
However, degrees of vulnerability may generally be defined as follows:
1 • Ecoregion is characterized by 0.0-0.29 average number of endangered species per county.
2 • Ecoregion is characterized by 0.3-0.49 average number of endangered species per county.
3 - Ecoregion is characterized by 0.5-0.99 average number of endangered species per county.
4 - Ecoregion is characterized by 1.0-1.99 average number of endangered species per county.
5 - Ecoregion is characterized by more than two endangered species per county.
F. Degrees of Vulnerability for Terrestrial Organism Populations
For the ecological function, terrestrial organism production, it is assumed that vulnerability
can be defined as the presence or absence of Federally endangered or threatened species.
An endangered species is one that is in danger of becoming extinct through all or a
significant portion of its natural range. A threatened species is one that is likely to become
endangered in the foreseeable future.
F-2
-------
The degrees of vulnerability which were used for the terrestrial organism function are
defined as follows:
1 - Ecoregion is characterized by an average of 0 to 1 endangered species per county.
2 - Ecoregion is characterized by an average of 1 to 1.9 endangered species per county.
3 • Ecoregion is characterized by an average of 2 to 2.9 endangered species per county.
4 - Ecoregion is characterized by an average of 3 to 3.9 endangered species per county.
5 - Ecoregion is characterized by an average of 4 or greater endangered species per county.
G. Degrees of Vulnerability for Primary Productivity
The primary productivity function reflects the rate of carbon fixation by vegetation. Some
ecoregions have very high growth (or recovery) rates while other ecoregions have very low
growth (or recovery) rates. To help develop a ranking system we have extracted
information from Whitaker (1975) to determine the range of primary productivity and define
numeric values. The degrees of vulnerability for primary productivity are defined as follows:
1 - Predominant natural vegetative cover type for ecoregion is characterized by mean net
primary productivity rate of > 1600 to 2000 grams per square meter per year.
2 - Predominant natural vegetative cover type for ecoregion is characterized by mean net
primary productivity rate of > 1200 to 1600 grams per square meter per year.
3 - Predominant natural vegetative cover type for ecoregion is characterized by mean net
primary productivity rate of > 800 to 1200 grams per square meter per year.
4 • Predominant natural vegetative cover type for ecoregion is characterized by mean net
primary productivity rate of > 400 to 800 grams per square meter per year.
5 • Predominant natural vegetative cover type for ecoregion is characterized by mean net
primary productivity rate of 0 to 400 grams per square meter per year.

Data Management Techniques
In order to deal with the vast amount of data involved in the ecological risk model, Region 6 has
developed an Ecological Risk Management System. This system is based on a PC/DOS platform
using the application software dBase m+. Since special characters and fonts were used to print
out the analyses and because of time constraints, the system was developed for two types of
printers: the Hewlett Packard Laser, and the Citizen MSP-15. In its present state, the system uses
approximately 2.6 KB of disk space (1.8K is for data, and 0.8K is for the system programs). The
system has several features which include:
1) limited user interface (menu driven),
2) Data update procedures for inputing and modifying Ecoregion, Environmental
Problem, Environmental Function, Impact Site, Vulnerability, and Data Quality
data,
3) Risk Index Matrix calculations and output procedures,
4) Risk Vulnerability reports, and
5) Data Set listings.
The features that we hope to implement in the future include:
1) Data Quality analysis,
2) Automated conversions for unit data (square miles to acres...),
3) Export/Import routines (Importing program data and exporting to Arcinfo GIS
for map production),
4) Sensitivity analysis,
5) Extended printer options,
6) Improvements in computational and output speeds, and
7) Developing and implementing risk models for the Human and Economic
concerns.

GLOSSARY
Abiotic - Devoid of life; nonliving.
Abiotic Stability - The ability of abiotic components of an ecosystem to withstand or recover from
an impact from a stressor.
Aquatic Organism Production - The ability of an ecosystem to maintain diverse and stable
communities of aquatic organisms.
Area of Impact - An area subjected to a given stressor measured in acres, hectares, sq.km., stream
miles, etc.
Areal - Any particular extent of space or surface area as a geographical region.
Biotic - Pertaining to life or living organisms, caused or produced by or comprising living organisms.
Cumulative Impact - Is the impact on the environment which results from the incremental impact
of the action when added to other past, present and reasonably foreseeable future actions
regardless of what agency (Federal or Non-federal) or person undertakes such other actions
(NEPA, 1970).
Degree of Impact - The severity (intensity and duration) with which a stressor acts on an indicator,
on a relative scale. This is a characteristic of the problem or stressor.
Degree of Vulnerability - See Vulnerability.
Diversity - A measure of biotic stability, as measured by species richness and populations numbers.
Ecological Risk Assessment - Ecological risk assessment is a procedure for estimating the
probability of and severity of adverse effects on species, biotic communities, and ecosystem
structure and function.
Ecological Risk Index • Numerical index which depicts an ecological risk value for use in relative
ranking.
Ecoregion • Large scale regions (15,000 - 33,000 sq.km.) delineated on the basis of patterns of
climate, soils, geology, vegetation, and physiography (Omernick, 1987).
Ecosystem - Includes the biotic community and the abiotic environment for a given area.
Ephemeral • Relating to a stream or a portion of a stream that flows only in direct response to
precipitation and receives little or no water from springs or no long-continued supply from
snow or other sources and its channel is at all times above the water table; lasting for only
a day, short-lived or transient.

Filtering and detoxifying of pollutants - The ability of an ecoregion to remove or make harmless
contaminants, excess nutrients, or paniculate matter from air, water or soils. The
assimilative capacity of an ecoregion is determined by soils, topography, micro-organism
populations, vegetative uptake strean flow and wind velocities.
Hydrology - For purposes of this study the mechanism for distributing water and nutrients across
the surface of the landscape dealing only with surface and groundwater available to non-
human populations within an ecoregion.
Geographic Information System (GIS) - Computerized mapping system used to automate,
manipulate, analyze and display geographic data in digital form. The major advantage of
a geographic information system is that it allows you to identify the spatial relationships
between map features. In the ecological report the GIS maps depict environmental risk
index values for each ecoregion by program stressor.
Primary Production - For purposes of this study, the conversion of sunlight into organic matter
which is available to non-human populations. The indicator of impact to primary production
is vegetative populations which generally produce food for non-human populations.
Residual Risk - The risk that remains given current levels of control in place and current levels
of non-compliance with regulatory requirements.

Residual Risk Formula - ERI = S S A/(/A£ D/( Dv
j=li=0
Stability - Resiliency or ability of an ecosystem (biotic and abiotic) components to withstand or
recover from an impact from a stressor.
Stream Density - Number of stream miles per square miles of drainage area.
Soil Production - This is the ability of an ecoregion to maintain a dynamic soil environment. In
a healthy soil environment weathering of sediments/lithologies, growth of soil macro- and
micro-biota, and the degradation of organic material continue at a rate where inputs are
balanced against outputs. When soils are stressed by environmental effects, organic matter
may be lost, biota is stressed or eliminated and weathering rates and products are effected.
A stressed soil will have a reduced capacity to produce normal soil gases, and act as a filter
against contamination of groundwater.
Standard Metropolitan Statistical Area (SMSA) - To be designated as a Standard Metropolitan
Statistical Area in 1980 an area had to have at least one city with a population of 50,000
or more or have a total urbanized population of 100,000 (75,000 in New England). The
standards for SMSA designation specify that the counties which include the central city and
adjacent counties, if they are at least 50% urbanized, be included in the SMSA. After
1980, the term "statistical" was dropped in SMSA, therefore the new term is SMA

-------
Terrestrial Organism Production - The ability of an ecosystem to maintain diverse and stable
connunities of terrestrial organisms.
Vulnerability - Unique characteristics of each ecoregion which determines it sensitivity to a
stressor. In this study there were a variety of indicators used to represent vulnerability
including endangered species, primary productivity rates, stream flows, and wind velocities.
