Limited Review of EPA's Risk Assessment for the
Hazardous Waste Identification Rule (HWIR)
Summary
We have given a quick look at EPA's draft 2,000 page (albeit
incomplete) risk assessment methodology supporting the Hazardous
Waste Identification Rule (HWIR) and have a variety of concerns
with EPA's approach. In addition, the analysis submitted by EPA
is incomplete/ contains errors, and apparently is undergoing
continous revision. As a result, we do not know whether (or to
what extant) EPA is addressing our concerns and those identified
in the Science Advisory Board review of EPA's methodology. What
we do know is that in some instances EPA's estimate of a "safe"
level for a chemical is hundreds or millions of times lower than
that chemical's concentration in unpolluted soils. Adopting the
draft nv:Tiber3 as regulatory levels will release only a small
fraction of the low ri3k wastes currently regulated under
extremely expensive RCRA hazardous waste standards. We are very
concerned that both we and EPA will not have enough time to
review these issues before the August 15 judicial deadline for
the HWIR proposal.
Liziita to a Full Raviaw of Draft Methodology
Three constraints preclude our ability to undertake a
comprehensive review at this *30 int. First, EPA has not ~ivan U3

methodology. Second, EPA is currently revising parts of the
draft methodology it has already provided us. Third, EPA staff
told the SAB that the current version of the methodology contains
numerous arithmetic errors. Based on EPA's expected schedule to
complete the risk assessment, we do not expect to have an
opportunity to review a complete methodology and results before
the judicial deadline.

three principal.concerns with EPA'3 rulemaking schedule:
(1) there is no time for an external review of the complete
methodology; (2) there is no time for validation of the
methodology with actual site data; and (3) there is no time to
characterize the degree of conservatism imbedded in the "safe"
levels. In its recent public hearing on the HWI3. risk
assessment, EPA's Science Advisory 3oard (SAB) raised similar
questions. The SAB is unlikely to complete its formal report on
this risk assessment package before the end of the summer.
The HWIR Methodology'• General Approach
The analysis assumes that industry manages solid waste in three
different ways. For each of these management methods, EPA
evaluates 43 different ways waste could migrate from the dumps to
humans or wildlife. The analysis back-calculates the waste
concentration that will ensure the human or environmental
receptor does not face a risk above EPA's risk goals (for
example, a one-in-a-million increase in cancer risk over a
lifetime). For all 129 waste unit/exposure pathway combinations,
EPA- sets the lowest back-calculated waste concentration as the
draft "safe" level for that chemical.
Concerns with "Results"
The analysis list3 draft "3afa" levels for each chemical in the
analysis. As the table below indicates, some calculated "safe"
levels are lower than the concentration typically found in
uncontaminated soils. If wastes with concentrations lower than
these "safe" levels are the only wastes that would exit hazardous
waste regulation, hazardous wasts wi^ld have to be "cleaner" than
background soils.

In addition, the exit values for three other metals — nickel,
mercury, and copper — are within the range of natural
concentrations in U.S. soils.1 People are also exposed to
chemicals in other settings. For example, benzo(a)pyrene is
found in burnt meat and other roasted food. The benzo(a)pyrene
concentration In a cup of coffee i3 often 100,000 times greater
than EPA's draft exit level. As stated above, these numbers may
or may not be the proposed exit levels, because EPA staff will be
trying to correct arithmetic errors and other analytic problems
in the risk assessment.
Methodology Problems
To calculate a "safe" level, EPA makes six explicit conservative
assumptions in each of the 43 different risk assessment pathways.
The methodology includes two conservative "assumptions for the
source contamination in the tank, ash pile, or other waste
management unit, two conservative assumptions for the migration
of contaminant from the waste unit to the human receptor, and two
conservative assumptions for the human or animal intake. The
analysis does not calculate the cumulative level of conservatism
— e.g./ 99.999 percent of the population would be exposed to
lower risks — of these six conservative assumptions. In
addition, since one pathway uses one set of six conservative
assumptions and another pathway uses a different set, it is very
hard to compare the level of conservatism across the 43 pathways.
It is even more troubling to find/ though, that the analysis
contains a number of additional implicit conservative assumptions
in methodologies or input data. A few of these implicit
assumptions or problematic methodologies are discussed below:
» Slo Siodagradatisa. SPA stiff state that, for over 70
percent of chemicals, the calculated "safe" pathway assumes
waste is managed in land treatment units (LTUs). In LTUs,
operators spread contaminated sludges onto a field and till

-------
• Soil Runoff Mathodology. SPA fundament a 11 y misapplies an
empirical equation to predict how much of eroded soil
reaches an adjacent stream or agricultural field.3 Thirty-
two percent of the draft exit levels depend on. this
erroneous approach.
• No Othar Snvironmantal Regulations. Certain exposure
pathways are barred or substantially reduced by non-RCRA
environmental regulation. For example, EPA stormwater
control regulations limit contaminated soil runoff.4 Wind-
blown dust is constrained by EPA's particulate matter
standards. EPA's BACT, MACT, and other air emission
standards control volatile organic emissions from tanks.
The analysis appears to assume that other regulatory
controls do not exist or that practices violate other EPA
regulations for decades.
* Equilibrium Analyiis. The analysis assumes that
contaminants bound to 3oils and sediments disperse
throughout a water body or field as soon as they reach it.
In a very recent SAB review of this approach in another risk
assessment document, the SAB found that these equilibrium
assumptions are unsuitable for regulatory purposes due to
the substantial scientific uncertainties in the models.5 In
general, equilibrium models overpredict off-site
contamination.
* OŁf-Sito Wind Conditions. In many key pathways, an off-site
agricultural field is contaminated by wind-blown dust from a
LTU. The local winds are curious; in EPA's methodology,
Wind blows across the LTU and scatters contaminated dust
onto the farmer's field, but does not blow any dust off of
the farmer's field.4 It is also unclear whether EPA even
assumes that soil erodes from the farmer's field.7 By
allowing contaminants to enter the field and restricting the
ways to exit, the analysis overstates the likely
jbryc.-aura Scana-io
The calculated "safe" levels for the pathways are derived from
some physically impossible scenarios of human exposure. In
addition, some exposure scenarios, while not physically
impossible, are highly improbable. The analysis provides little
information for the public to ascertain how probable (and thus
protective) the exposure scenarios are.
Location Unisa. In -iach sxcosurs scenario, EPA locates
-------
- 5 -
subsistence farmer's field in the area downwind from a la'rge
LTU that has the maximum dust deposition. Although there is
some small possibility that these scenarios could occur,
without an estimate of the probability, policy officials and
the public can not determine whether EPA's draft levels are
protective in 90, 99, or 99.999999 percent of actual LTU
conditions.
Human Residency Immediately After Waate Placemant. For
sixty percent of the chemicals, the calculated "safe" levels
assume an adult or child takes up residence on the waste
unit immediately after it closes (assumed to be 40 years
after waste placement). It is hard to imagine this scenario
unless.local zoning officials and private developers
conspire to mask the property's past use. Residential
construction would generally place additional soil on the
waste layers to block exposure. Although there is a very
small possibility that this scenario could occur, the
analysis does not estimate the likelihood.
Subsistence Fisher. Nine percent of the exit levels are
designed to be protective of a fisher using a small stream
for subsistence fish consumption. In these situations,
contaminated soil erodes from a large LTU, reaches the
stream, and either settles to the bottom or flows suspended
in the water. However, EPA constrains the maximum amount of
sediment in stream flow to levels tolerable to fish.
Therefore, because EPA's methodologies overpredict the
amount of sediment that reaches this stream, a large amount
— four inches of sediment -r settles on the bottom of the
stream channel each year.® Since the stream channel is only
on average seven inches deep, this extreme sedimentation
would likely fill up the entire channel within a few year3.
Real streams do not silt up so quickly.'
To predict exit levels, the analysis is based on the
consumption.'*15 I^A ccr.juzptier, rirss for -his

River is 250 times longer and has a flow rate 1*7, 000 times
greater than the small stream in the analysis.12 Fish are
certainly less plentiful and smaller in a smaller stream of
the sort modelled by EPA. A subsistence fisher would have
to expend a much greater effott to catch the same amount of
food a3 the Columbia River fishers. Despite the poor

Fruit aiid Vogotabl* Crop Yields. EPA*s assumed subsistence
farmer grows ninety percent of his or her yearly consumption
fruit, leafy vegetables, fruiting vegetables (e.g.,
tomatoes, cucumbers), and legumes on a 75-acre field.
However, given EPA's consumption and crop yield assumptions,
the farmer needs over 480 acres of land to grow enough food
that EPA assumes he or she eat3.14 The risk assessment's
values must be erroneous. For example/ the analysis assumes
an eleven square-foot patch yields only 20¦milligrams of
edible fruit.15

2. An EPA report calculates the neutral (pS = 7) hydrolysis
half-life for phorate to be 96 hours. (See Jackson, J. et al.,
"Measurement of Hydrolysis Rate Constants for Evaluation of
Hazardous Waste Land Disposal: Volume 3. Data on 70 Chemicals,"
Environmental Research Laboratory, Office of Research and
Development, EPA, 1900.) The lowest exit level for phorate is
exposure pathway 9 for a land treatment unit, assuming a
subsistence farmer consumes root crops grown directly on top of
the closed unit. (See Review Draft, Table 8-1).
3. EPA used an empirical equation to estimate sediment delivery
ratio from Vanoni, V.A., Sediment Engineering, American Society
of Civil Engineering, 197T! Although researchers generally
estimate watershed-specific sediment delivery ratios, Vanoni
formed a general relationship from the work of many authors. In
Vanoni's empirical equation, a basin's sediment delivery ratio is
proportional to the -1/8 power of the drainage area. However,
Vanoni's derived hi3 empirical relationship from sediment
measurements of complete drainage basins, not incomplete
watersheds like a waste'management unit. In these empirical
models, mobilized soil either travels to a channel or settles
inside the drainage basin. Across the waste management unit,
mobilized soil either travels to a channel or settles on
adjoining land outside the waste management unit. Since eroded
soil from the waste management unit could come to rest on land
elsewhere in the watershed, the percentage reaching water bodies
is likely to be far less than EPA's value. As a further
illustration of this problem, EPA oftan uses another empirical
model to estimate sediment delivery ratios.

6. The constant to account for soil losses in the off-site
agricultural field includes a leaching constant, a degradation
constant (set to zero), a volatilization constant, a surface run-
off constant, a soil erosion constant, but riot a soil loss
constant to account for particulate erosion. See equation 6-102
on page 6-167 of the Review Draft, for example.
7. In the example calculations presented to the Science Advisory
Board's subcommittee, there is no value for the soil loss
constant due to soil erosion. However, as discussed in the
previous note, the analysis explicitly includes this loss
mechanism.
8. In the example calculations presented to the Science'Advisory
Board's subcommittee, the" rate of burial in the stream (Equation
6-397) is 0.1 meters, or approximately four inches per year.
9. If a watershed really had such high levels of erosion, much
more sediment would likely stay suspended in the water and thus
preclude extensive aquatic life.

1.0 INTRODUCTION
This document is a supplement to the Technical Support Document for the Hazardous
Waste Identification Rule: Risk Assessment for Human and Ecological Receptors, dated August
1995. It describes changes in methods and inputs since the August 1995 document, and corrects
a few errors in the August 1995 document.
This document is organized into 5 sections. This introductory section provides an
overview of the changes and document corrections, and provides an index to sections, tables, and
equations in the August 1995 document affected by the changes and corrections. Section 2 of
this document describes each of the changes or corrections in more detail, and includes revised
equations or tables as necessary. Section 3 provides references. Following the references are
updated Appendices A (chemical properties data, updated to include silver), B (new ecological
toxicological profiles for several chemicals), and D (revised central tendency results) and new
results (as revised tables for Section 8 of the August 1995 document; bound separately).
Many of the changes apply to more than one section of the August 1995 document, and
some sections are affected by more than one change. To assist the reader in locating changes.
Table S-l lists sections, tables, and equations in the August 1995 document affected by the
changes described in this document, and shows which changes apply to each affected section.
The changes are identified in the table by the number used below.
1.1 Changes in Methods
Many of the changes in the methods used in the analysis involved adding additional loss
mechanisms in soil or water throughout many of the pathways. These include:
1. Biadegradation (corrected) and hydrolysis (added) in the land application unit
2. Biodegradation, hydrolysis, erosion, and runoff losses from the off-site field
3. Biodegradation, hydrolysis, and volatilization losses from surface water
4. Burial and volatile losses in surface water for surface impoundment spills
In addition, several changes were made to pathways involving soil erosion to an,off-site field,
including:
5. Correction to account for soil eroding onto the off-site field and adjustment to the
sediment delivery ratio to account for sources that are significantly larger than the
receiving field

1.0 INTRODUCTION
6. Elimination of the soil erosion pathway for waste piles when the receiving field is large
relative to the waste pile (i.e., for ecological receptors and cattle)
7. Elimination of high end parameter combinations for the land application unit to eliminate
situations where the receiving field is significantly larger than the source
Finally, one change in the scenario for closed land application units was made:
8. A 10 year period of non-use between closure and the start of any activities leading to on-
site exposures was added
1.2 Changes in Input Values
The input values for the following parameters were changed:
9. Several ecological benchmarks were revised
10. The stream order used to determine inputs for the high end waterbody was changed to
reflect a larger stream
11. The Universal Soil Loss Equation (USLE) length slope factor for land application units
was changed to reflect 2 percent slope for consistency with the groundwater analysis

2.0 DESCRIPTION OF CHANGES AND CORRECTIONS
This section describes each of the changes or corrections and provides revised equations
and tables where necessary. For each change, the original approach documented in the August
1995 document is described, followed by a description of the revised approach. Section numbers
refer to the August 1995 document unless explicitly identified as referring to this document.
Revised tables and equations are provided at the end of each subsection, following any
discussion, and retain the table or equation number from the August 1995 document. New
equations, where necessary, are given the number of the equation they should follow, plus a
letter. For example, equations inserted between original equations 6-1 and 6-2 would be
numbered 6-la, 6-lb, etc.
2.1 Biodegradation and Hydrolysis in the Land Application Unit
Original approach: Releases from the land application unit were partitioned among
volatilization, runoff, leaching, and biodegradation. Using a small time step (l/50th of a year, or
about 1 week), each loss was calculated sequentially for the time step. Biodegradation rates were
based on half-life data from Howard (1991), and were assumed to include transport losses such
as volatilization. Therefore, to estimate biodegradation losses, calculated losses for
volatilization, runoff, and leaching were subtracted from the total loss implied by the half-life
(see Equation 7-38). If these losses exceeded the total loss, biodegradation losses were set to
zero. Checks were made to ensure that the sum of all losses did not exceed the total mass of
contaminant available.
Revised approach: Further review of the biodegradation data suggest that these values should be
taken to exclude transport losses, and therefore used directly to calculate biodegradation losses.
In addition, hydrolysis half-life data from Howard (1991) were also used. For hydrolysis half-
lives less than one year, the half-life was converted to a rate and used. Where hydrolysis half-life
was longer than a year, hydrolysis was not considered to be an important loss mechanism, and
was not included. The biodegradation and hydrolysis half-life data and corresponding rates are
shown in Table A-6 (new table; provided at the end of this document as part of a complete
Appendix A).
All of the loss processes modeled in the partitioning are assumed to be first-order (see, for
example, U.S. EPA, 1993a, in which volatilization, leaching, runoff, and biodegradation losses
from soil are assumed to be first-order). A first order rate constant was calculated for
volatilization, leaching, and runoff losses and added to the first order biodegradation and
hydrolysis rate constants from Howard (1991) to determine an overall loss constant. This overall
loss constant is then applied to the initial mass of contaminant for a particular time step, and the

total loss calculated. This change typically has little effect on the results, but ensures that in
situations where the different loss processes must compete for a limited quantity of contaminant,
that actual fosses to each mechanism accurately reflect that. Equation 7-27 has been revised to
reflect this change, and several new equations (7-27a, 7-27b, 7-27c, and 7-27d) have been added.
Equation 7-38 should be deleted.
The use of a single biodegradation or hydrolysis half life introduces some uncertainty to
the analysis. It is widely recognized that half-life data is a function of both the inherent physical
and chemical properties of the constituent, as well as the physical and chemical properties of the
contaminated media (Mackay et al. (1992)). In addition, there very often is a wide range of half-
life values Sir a given chemical in the literature. However, many studies and respected references
which contan compilations of literature data, such as Howard et al. (1991) (henceforth referred
to as "Howard'), do not include a complete description of the physical and chemical properties
that exist is the contaminated media under study. Therefore, the selection of a single half-life
value for use in the model implies that the environmental conditions ttiat existed in the selected
study are approximately the same as the environmental conditions simulated in the model.
Howard w* used as the primary reference for half-life data even though it may be somewhat
limited witk respect to the level of detail it includes concerning the physical and chemical
characteristics of the contaminated media. In addition, there also exists some question as to
whether thehalf-life values cited in Howard reflect the effects of not only degradation but also of
abiotic transport processes such as leaching and volatilization. However, the Howard reference
specifically states that the degradation half-life data do not include the effects of transport
processes. Also, the half-life data for a given media are coupled with a brief description of the
type of degndation process which corresponds to that data. Therefore, the data obtained from the
Howard reference appear to represent a single degradation process, and thus can be used in the
model withoot any adjustments. In addition, Howard is presented as a "...valuable source of
...half-lives-" in Mackay et al. (1992), another respected source of physical and chemical
property compilations for organic constituents.
Effects of Physical and Chemical Characteristics of Soil on Degradation Half-Lives
The physical and chemical characteristics of soil affect both the microbial populations in
soil and the subsequent aerobic biodegradation potential of soil. Some of these same physical and
chemical characteristics can also affect hydrolysis rates. There are a number of properties that
are believed to affect degradation rates in soil, such as:
(1) Jle oxygen level
Molecular oxygen serves two different functions during aerobic biodegradation of organic
compounds: I) it acts as a final electron acceptor for those electrons liberated during the
November 1995
-------
2.0 DESCRIPTION OF CHANGES 2.1
degradation of organic compounds; and 2) oxygen may also function as the reactant
during the initial steps of organic compound biodegradation. The supply of available
molecular oxygen often limits the extent of biodegradation in contaminated media.
(2) pH
The pH of a system may also affect the biodegradation rates in a media. Studies have
been conducted that indicate microbial growth and subsequent biodegradation will be at a
maximum if the soil/microbe environment is maintained within a certain pH range.
Certain microorganisms may only be viable or may only be capable of metabolizing
organic compounds if their environment is maintained at a certain pH range. Therefore,
there may be differences in biodegradation rates of similar organic compounds if the pH
is different in the environments containing the compounds. For example, the
biodegradation rate of a given compound in soil with a pH of 3 may be smaller than the
biodegradation rate of that same compound in a soil with a pH of 6.5. This pH difference
may indicate that different types of microbial populations are present in the contaminated
media and thus the potential for biodegradation may also be different in the media.
The pH of an aquatic system also affects the hydrolysis rate. Surface waters with a
typical aquatic pH range of 5

increase in the oxygen available to the microorganisms.
(5) mineral nutrients
The addition of organic carbon contaminants to a system also necessitates an additional
increase in the amount of essential nutrients (e.g., inorganic nitrogen and phosphorous) if
the nutritional balance is to be maintained in the system. Otherwise, the microorganisms
involved with biodegradation will not have the resources necessary to conduct this
process.
(6) moisture content of soil
The amount of water present in the soil pore spaces affects the rate at which oxygen can
diffuse into the soil; oxygen diffuses through air faster than through water. Higher
oxygen contents in soils serve to stimulate aerobic biodegradation. However, soil
moisture also transports nutrients and organic substrate to the microorganisms in the soil.
Whereas, too little soil moisture would inhibit both transport and subsequent
biodegradation processes..
As discussed above, there are several factors which can affect soil degradation half-lives.
Therefore, it is not unusual to see significant variationsin published half-life data given the
heterogeneous nature of soil from different locations. As a result, uncertainty is introduced when
half-life data from the literature is used in the model without there being more information on the
specific chemical and physical characteristics that existed in the media when the data was
collected. This analysis assumes neutral pH, a constant temperature of 25 C, and fairly moist soil
conditions. Applying these biodegradation rates using these steady state assumptions does not
account for the environmental variability relevant to biodegradation. A more correct approach
would be to use kinetic models that account for the above factors. For most situations, the
approach used is not conservative, and will tend to overestimate biodegradation for many
environmental conditions across the country. For example, winter temperatures in much of the
country would probably preclude significant degradation during the winter months.
As the discussion and examples presented above demonstrate, there are several factors
associated with the degradation half-life data that introduce uncertainty to this analysis.

2.2 Biodegradation, Hydrolysis, Erosion, and Runoff Losses in Off-site Field
Original Approach: Pathways involving contamination of an off-site field include a loss term
that accounts for loss of contaminant from the soil by volatilization, leaching, and erosion/runoff.
The pathways incorporating this term include pathways involving soil erosion to an off-site field,
air deposition to off-site field, and deposition to watershed. For soil erosion and deposition to an
off-site field, this loss term included only volatilization and leaching, while for deposition to
watersheds, it included volatilization, leaching, erosion, and runoff.
Revised approach: This loss term has been modified to include losses to biodegradation and
hydrolysis for both off-site fields and watersheds, and to add erosion and runoff for off-site
fields. The original approach allowed for a balance in the amount of soil eroded onto and off of a
field, but allowed contaminant to be eroded or deposited onto the field but not lost by erosion,
leading to an accumulation of contaminant.
Because this loss term appears in several pathways, the affected equation appears several
times in the original document. Equation 6-2 has been revised to reflect the correct equation for
all instances of the soil loss constant; in some instances, only biodegradation and hydrolysis were
added, while in others, erosion and runoff were added as well. The revised soil loss constant
equation applies to the pathways, sections, and equations from the August 1995 document listed
in Table S-2.
The discussion of uncertainty regarding soil degradation and hydrolysis found in Section
2.1 of this document applies here as well.

2.3Riodegradation, Hydrolysis, and Volatilization Losses from Surface Water
Original Approach: Pathways involving contamination of surface water include a dissipation
tern that accounts for loss of contaminant from the water column by volatilization and burial in
sediment. The pathways incorporating this term include pathways involving diffusion from air
diroctly to surface water, soil erosion to surface water, and deposition to watershed. For soil
eroson to surface water and deposition to a watershed, this loss term included only burial in
secfinent, while for diffusion from air directly to surface water, it included volatilization and
bural in sediment. Volatilization losses were omitted for overland pathways because
cofl&minants that have a tendency to volatilize would likely do so before reaching the waterbody.
Reused, approach: This dissipation term has been modified to include losses to biodegradation in
the »ater column, hydrolysis in the water column and sediment, and volatilization where it had
beei omitted. Volatilization losses, though not likely to be significant for the overland pathways,
havt been included in the overland pathways for completeness.
Because this dissipation term appears in several pathways, the affected equation appears
sevoal times in the original document. Equation 6-13 has been revised to reflect the correct
equaion for all instances of the dissipation rate; in some instances, only biodegradation and
hydnlysis were added, while in others, volatilization was added as well. The equations for
caladating inputs to the volatilization term (overall transfer rate and dissolved fraction) appear in
the August 1995 document in several places (for example. Equations 6-17 and 6-19) and are not
repoted here. The dissipation equation in the August 1995 document contained two
typographical errors; these are also corrected in the revised equation. The revised dissipation rate
equ«ion applies to the pathways, sections, and equations from the August 1995 document listed
in Tile S-3,
The discussion of uncertainty regarding soil degradation and hydrolysis found in Section
2.1 of this document applies to degradation in water as well.

Original approach: Pathways involving contamination of surface water include a loss term that
accounts for loss of contaminant from the waterbody by several different mechanisms, including'
volatilization and burial in bed sediment. These loss terms were inadvertently omitted from the

Revised approach: Losses due to volatilization, burial, biodegradation, and hydrolysis have been

affected by this change. Equations 6-142a, 6-143a, 6-144a, and 6-144b have been added to
illustrate this calculation for surface impoundments. In addition, Equation 7-69 has been revised.

2.5 Correction to Account for Soil Eroded to Off-site Fields and Adjustment to
Sediment Delivery Ratio
Original approach: The equation for backcalculating the soil concentration in a waste
management unit from the soil concentration in an off-site field contaminated by erosion from
the source did not account for the mass of soil added to the Field via erosion.
In addition, the sediment delivery ratio, a term that describes how much of the soil eroded
from the source reaches the off-site field, did not adequately account for differences in area
between the source and receiving field. The sediment delivery ratio was adjusted using a ratio of
the two areas if the receiving field was smaller than the source.
Revised approach: The equation for backcalculating on-site soil concentration from off-site soil
concentration has been revised to include a term to account for the soil eroded onto the off-site
field (Equation 7-12 for land application units and 7-50 for wastepiles). In addition, the equation
for sediment delivery ratio (Equation 7-14 for land application units and 7-51 for wastepiles) has
also been revised to use a ratio of the square root of the areas of the source and receiving field, as
suggested by the Dioxin document (U.S. EPA, 1994a). While these equations appear in Section
7 (7.3.5.3 and 7.4.5.3), they are also discussed in Sections 6.3.2.2, 6.6.1.2.4, and 6.6.2.2.4.

2.6 Elimination of Erosion Pathways with Source Much Smaller than Receiving Field
Original approach: Several modeled scenarios for soil erosion involved a situation where the
source is much smaller than the receiving field. This occurs for the wastepile .when the receiving
field is an agricultural field for beef/milk pathways (pathway 11 off-site) or an ecological habitat
for ecological pathways (pathway Terr II). The area of the agricultural field is 2,000,000 nr for
central tendency, and 300,000 nr for high end; the area of the ecological habitat is 2,000,000 nr.
The wastepile area, by contrast is 120 m2 for central tendency and 5,300 m2 for high end.
Revised approach: The correction to the sediment delivery ratio used for erosion pathways
described in section 2.5 accounts for situations where the receiving field is smaller than the.
source. In this case, where the receiving field is much larger than the source, even using the
larger wastepile and the smaller field, it seems unlikely that this will be an important pathway
given the disparity in areas. Therefore, pathways 11 (off-site) and Terr II were dropped for
wastepiles.
2.7 Correction to Erosion Pathways with Source Much Larger than Receiving Field
Original approach: Pathway Terr II, soil erosion to an ecological habitat, uses an ecological
habitat area of 2,000,000 nr. When the land application unit area is set to its central tendency
value (61,000 m2), this combination of parameters results in a scenario unlikely to be of concern
as only a small portion of the 2,000,000 m2 is likely to be contaminated.
Revised approach: The sediment delivery ratio adjustment for erosion to an off-site field
described in section 2.5 is an adequate adjustment when the source area is somewhat larger than
the receiving field. In this case, the difference is greater. Therefore, the land application unit
parameters are always set to high end values for the Terr II pathway. Only one other fate and
transport/waste management unit characterization parameter is set to high end values, to maintain
two of these parameters set to high end values.

2.8 Ten-year Period of Non-Use Before On-site Exposures on Closed Land Application Unit
Original approach: In the original approach, exposures to residential receptors on a closed land
application unit were assumed to start immediately upon closure of the unit, with no period of
non-use for changes in land use or residential construction. This was not considered to be a
realistic scenario.
Revised approach: The model has been revised to allow a 10-year period of non-use between
land application unit closure and the start of any on-site residential exposures. This more
realistic scenario allows time for zoning changes and residential development. However,
because the chemicals of concern in the on-site closed land application unit pathways are highly
persistent, the change has little effect on the exit criteria backcalculated.

2.9 Revised Ecological Benchmarks
Since the release of the August 1995 document, some of the ecological benchmarks have
been changed to incorporate new data/analyses and several preliminary comments. In particular,
the toxicological profiles presented in Appendix B have been expanded to provide detail on the
calculation of soil fauna benchmarks and aquatic community benchmarks. The sediment
community benchmarks have also been revised to reflect changes in input data (e.g., log K^.) and
assumptions (e.g., organic fraction or f^) used in the multiple pathway model. In preparing
additional materials for the profiles, it was discovered that some of the benchmarks for fish.and
aquatic invertebrates were incorrectly reported in ^g/L instead of mg/L in Table 4-4 in Section
4.3.2. These values have been corrected and are presented in Table 4-4 below. It should be
noted that these benchmarks are. the values that were used in the most recent model calculations.
The following sections present supporting calculations and data for the revised soil fauna
benchmarks (see Section 4.3.4, revised sediment community benchmarks, and the aquatic
benchmarks (see Section 4.3.5) derived using Tier II methods described in the August 1995
document (i.e., secondary chronic values). The expanded materials for the ecological toxicity
profiles will result in this reorganization of the tables:

2.9.1 Soil Fauna Benchmarks
For soil fauna, soil ecological toxicity benchmarks were developed using methods
analogous to those used in deriving the National Ambient Water Quality Criteria (AWQC). In
brief, the soil fauna benchmarks were estimated to protect 95% of the species found in a
"typical" soil community, including earthworms, insects, and other various soil.fauna.
Microflora were not included in the soil community primarily because of the difficulty in
assigning ecological significance to effects levels for soil microorganisms, especially with
respect to adaptation and recovery of microbial populations. It should be noted, however, that
microflora make up approximately 80-90% of the biomass and biological activity in soil.1 As
described in Section 3.3.3.2 of the August 1995 document, eight taxa of soil fauna we're
identified to capture the key structural (e.g., trophic elements) and functional (e.g., decomposers)
components of the soil ecosystem. The methodology presumes that protecting 95% of the soil
species with a 50th percentile level of confidence will ensure long-term sustainability of a
functioning soil community and, therefore, allow for multiple uses (e.g., residential, agricultural)
of the "contaminated" area.
The toxicity data on soil fauna were gleaned from several major compendia and
supplemented with additional studies identified in the open literature. Generally, studies were
not eliminated from the data set unless: (1) the statistical quality of the study data were deemed
inadequate, (2) the endpoint was considered inappropriate to develop benchmarks (e.g., LC^
values), or (3) the study species did not fit in any of the eight taxonomic categories. In short,
acceptable toxicity data were limited to soil studies (vs. aqueous studies) on measurement
endpoints believed to be relevant to population survival (e.g., growth, reproduction). Insufficient
data were identified within the time frame for this analysis to delineate the relationship between
toxicity and, the form of the metal applied to soil (i.e., sulfate, chloride). However, it seems
apparent that metal salts are both more mobile and more toxic in the soil community.
The approach to calculating benchmarks for the soil community was based on efforts by
Dutch scientists (i.e., the RTVM methodology) to develop hazardous concentrations (HC) at
specified levels of protection (primarily 95%) at both a 95th percentile and a 50th percentile level
of confidence. For the soil fauna benchmarks, the 50th percentile level of confidence was
selected because the 95th percentile appeared to be overly conservative for a "no effects"
approach. The key assumptions in the Dutch methodology are that: (1) NOEC and LOEC data
are distributed logistically, and (2) the 95% level of protection is ecologically significant. The
' Preliminary comparisons of toxicity data between soil fauna and microflora suggest that benchmarks for
soil fauna will likely be protective of microflora.

followiig formula was used to calculate soil fauna benchmarks:
H(-5% ~ \.xm • ~ Jm] (4-7)
where HCS% = soil concentration protecting 95% of the soil species
xm = sample mean of the log NOEC and LOEC data
k, = extrapolation constant for calculating the one-side leftmost
confidence limit for a 95% protection level
sm = sample standard deviation of the log NOEC and LOEC data
b is important to note that only one value for k, is calculated for the 50th and 95th
percerttk confidence limits, respectively, for each sample size (m). Consequently, it is assumed
that: (1) there is just one extrapolation constant with the required confidence property for each
species sample size, and (2) extrapolation factors may be determined through Monte Carlo
simulation by generating random sample averages and deviations for the standard logistic
distribslion and adjusting for a specified confidence level (i.e., 50th or 95th). Like the AWQC,
the me»s to verify protection of a true field community at the 95% level of protection are
currently unavailable or prohibited by cost.
The August 1995 document contained soil fauna benchmarks for five metals: cadmium,
copper,lead, mercury, and zinc. A reevaluation of the data on mercury indicated that toxicity
data woe available on an insufficient number of taxa to represent the soil community (i.e., less
than fow categories). As a result, the soil fauna benchmark for mercury has been withdrawn
pending the identification of additional data. The benchmarks for the other metals have been
revisedbased on an analysis of the appropriateness of the toxicity data with respect to the study
selectioi criteria described in Section 4.3.4. For example, a feeding study conducted in an
agar/fiagi matrix for nematodes (Aphelenchus avenae) was considered inappropriate for
benchnark development because the lead cation is highly available to the worms in this food
source. The study value of 0.082 mg/kg was omitted from the data set, resulting in an increase in
the soil fauna benchmark from the original value of 0.25 mg/kg to 28 mg/kg. In addition, the
data set for zinc has been expanded to include several lowest observed effects concentrations
(LOEG) to augment the species-specific data. Based on an analysis of all available data on zinc
toxicity to soil organisms, it was felt that the interim soil fauna benchmark of 0.036 mg/kg (based
on four studies) was inappropriately conservative and indicative of the importance of considering
as many of the eight taxonomic groupings as possible. A soil benchmark of 23 mg/kg was
derived from the expanded data set on zinc toxicity to soil organisms. The soil fauna

benchmarks for lead and copper have also been revised and are now 28 mg/kg and 21 mg/kg,
respectively.
Although background concentrations were evaluated with respect to the soil fauna
benchmarks (see Elements in North American Soils by Dragun and Chiasson, 1991), background
concentrations per se were not presumed to be appropriate target levels to protect the soil
community. Whereas background concentrations include naturally occurring metals that are
relatively immobile, hazardous waste streams contain a variety of metals species that may be
both mobile and, because of their bioavailability, highly toxic to soil fauna. In addition,
adaptation to background metals by indigenous soil communities may not be relevant to soils in
which metal-containing wastes are introduced over a much shorter time scale.
A series of tables is introduced in this section as a supplement to the toxicological
profiles in Appendix B. For each of the remaining metals - cadmium, copper, lead, and zinc -
two tables are presented that describe the calculation of the soil fauna benchmarks (Table 5) and
the data set upon which the benchmark was based (Table 6). Table 5 presents the calculation of
the soil fauna benchmark, including the equation (4-7) and all of the inputs (e.g., toxicity values,
standard deviation) required by the methods. Table 6 presents the complete data set from which
the soil fauna benchmark was derived and includes the SDecies. taxonomic erouDines. endDoints.

2.9.2 Revisions to Aquatic Benchmarks
This section presents updated secondary chronic values (SCVs) and sediment community
benchmarks to the August 1995 document. A number of aquatic benchmarks were based on
SCVs as described in Section 4.3.5 of the August 1995 document. In the appendix to the August
1995 document, the units on some SCVs were entered incorrectly in the ecological toxicity
profiles, although the correct values and units were used in the models. For the chemicals listed
below in Table 2.9-1, the SCVs have been updated to correspond to the model inputs.

In addition to these revisons, the following typographical errors have been corrected from the
August 1995 document:
• Hexachlorobenzene profile, Table 2, fish and aquatic invertebrates should be reported
as 6.0E-03, not 3.68E-03.
• Hexachlorocyclopentadiene profile, Fish and aquatic invertebrates text, the SCV
reported in the text should be 7.5E-04, not 6.9E-03.
• Mercury profile, Fish and aquatic invertebrates text and Table 2, the SCV of 1.3E-03
should be reported as a FCV of 1.3E-03.

2.0 DESCRIPTION OF CHANGES 2.9
—WWW—WII irjr.-r?.
As a result of updated SCVs, as well as revised K^. values, many of the sediment
benchmarks have also changed. As discussed in Section 4.3.6 of the August 1995 document, the
equilibrium partitioning (EqP) method was used to calculate the sediment benchmarks which are
equivalent to sediment quality criteria (SQC). For this analysis, the sediment f^ was assumed to
be 0.05, the mean value of the range suggested in the Addendum: Methodology for Assessing
Health Risks Associated with Indirect Exposure to Combustor Emissions (U.S. EPA, 1993a).
In the August 1995 document, the specific data used to calculate SCVs were
inadvertently omitted from the ecological toxicity profiles. The Tier II values were generally
taken from three sources in order of priority:
• Great Lakes Water Quality Initiative
• Toxicological Benchmarks for Screening Potential Contaminants of Concern for Effects
on Aquatic Biota: 1994 Revision (Suter and Mabrey, 1994)
• derived from AQUatic Toxicity Information REtrieval System (AQUIRE), 1994.
For a few chemicals, data available in AQUIRE were more recent than data presented in Suter
and Mabrey (1994). For these chemicals, an AQUIRE-derived SCV was preferred over the SCV
listed by Suter and Mabrey (1994). The sources of data for the SCVs calculated in Suter and
Mabrey (1994) and derived from AQUIRE are listed, by chemical, in the following tables. As
explained above, these tables may be inserted as Table 3 in the ecological toxity profiles in
Appendix B. The reader may refer to Section 4.3.6 in the August 1995 document for a full
explanation of the calculation procedures for SCVs.

2.10 Stream Order/Waterbody Characterization
Original approach: The waterbody used in the modeling was characterized using average values
for a selected stream order. For the original approach, the central tendency stream order was
stream order 5 and the high end stream order was stream order 3, a smaller stream providing less
dilution, and therefore higher chemical concentrations. However, there was some question as to
whether a stream order 3 stream was large enough to support a subsistence fisher, as was implied
by one of the scenarios modeled. (The characteristics of streams of various order are shown in
Tables 6-19 and 7-44 in the August 1995 document, and are not repeated here).
Revised approach: Because there is some controversy around the size of the high end stream
with respect to the scenarios modeled, the Agency decided to perform a second set of runs using
a larger, stream order 4 stream as the high end stream. Results for both stream order 3 and
stream order 4 as the high end stream are provided in the new results included with the present
document. The additional parameter values are shown below in a revised Table 6-20 (this
revised table should also be substituted for Table 7-45). This change affects inputs for most
equations associated with the sections and pathways noted in Table S-5.

2.0 DESCRIPTION OF CHANGES
2.11 Land Application Unit USLE Length Slope Factor
Original approach: The Universal Soil Loss Equation (USLE) uses a factor called the Length-
Slope factor (LS) as one input to determine the amount of soil eroded from a particular area. The
model uses the USLE in three different contexts: for erosion from a land application unit, erosion
from a wastepile, and erosion from a watershed, a single set of central tendency and high end
values were used for LS; these were 1 and 3, respectively, and were used for all three situations
in which the USLE is used. These reflect a range of possible slopes and distances that were felt
to be applicable to all three situations.
Revised approach: In order to be consistent with the groundwater analysis, which used a source
slope of 2 percent for the land application unit, LS was changed for the land application unit (but
not the wastepile) to reflect a 2 percent slope. The revised LS values for land application units
are 0.3 for central tendency and 0.5 for high end. These lower values will result in less erosion
off the land application unit. These revised values were also applied to the watershed in which
the land application unit is located, as this is likely to have a similar slope to the unit. This
change affects the pathways and sections noted in Table S-6.
2.12 USLE Cover Factor
Original approach: The Universal Soil Loss Equation (USLE) uses a factor called the Cover
factor as one input to determine the amount of soil eroded from a particular area. This factor was
set to values of 0.1 (central tendency) and 0.5 (high end), reflecting an average of values for
weeds and grasses assuming no canopy and 50 percent and 0 percent groundcover, respectively.
Revised approach: The USLE Cover factor values used were appropriate to a waste management
unit with no ground cover, but were considered unrealistic for off-site fields and watersheds,
especially since off-site fields were modeled as growing forage or vegetables. Therefore, the
USLE cover factor for off-site fields and watersheds was changed to reflect 80 percent and 40
percent groundcover, averaging values for weeds and grasses, and no appreciable canopy. The
new central tendency and high end values are, respectively, 0.03 and 0.1. This change affects the
pathways and sections noted in Table S-6.
