The National Sediment Contaminant Point Source Inventory is a database of point source
pollutant discharges that may result in sediment contamination, and a screening-level analy-
sis of chemicals, geographic areas, and industries based on potential to cause sediment con-
tamination. The data and information contained in this document could be used in various EPA
regulatory programs for priority setting or other purposes after further evaluation using program-
specific criteria. However, this document has no immediate or direct regulatory consequence. It
does not in itself establish any legally binding requirements, establish or affect legal rights or obliga-

National Sediment Contaminant Point Sourcle Inventory
Executive Summary
During the past two decades, the U.S. Environmental Protection Agency (EPA) has
focused its water pollution control efforts on protecting water quality within the
water column. This has been accomplished primarily by controlling municipal and
industrial point sources. More recently, EPA has begun to direct its efforts toward identify-
ing and controlling other threats to the aquatic environment, including the accumulation of
toxic chemicals in sediment. The Water Resources Development Act of 1992 (WRDA)
directed EPA, in consultation with the National Oceanic and Atmospheric Administration
and the Army Corps of Engineers, to conduct a comprehensive national survey of data
regarding aquatic sediment.quality in the United States. The Act required EPA to compile
all existing information on the quantity, chemical and physical composition, and geographic
location of pollutants in aquatic sediment, including the probable source of such pollutants
and identification of those sediments which are contaminated. The Act further required
EPA to report to the Congress the findings, conclusions, and recommendations of such
survey, including recommendations for actions necessary to prevent contamination of aquatic
sediments and to control sources of contamination. Volume 3 of this report (this volume)
addresses point sources. Vplume 4 of this report, when completed, will address nonpoint
sources. Chapter 4 of Volume 1 of this report describes all probable source categories.
EPA's Office of Science and Technology (OST) has led the Agency's efforts to compile
and analyze data for the National Sediment Contaminant Point Source Inventory. The screen-
ing-level sediment contaminant load analysis developed for and applied to this study cannot
be used alone to predict sediment contamination or to indicate where contaminated sedi-
ment problems have occurred or who is responsible. The major objectives of the inventory
and the analysis presented in this report are as follows:
Generate a relative ranking of chemicals and industrial categories based on 1993
Toxic Release Inventory (TRI) and 1994 Permit Compliance System (PCS) chemi-
cal release data.
Prioritize watersheds for collection of additional information that might lead to
the identification of additional monitoring needs or pollution prevention oppor-
tunities.
Establish a baseline to which additional or future inventories can be compared.
The inventory includes more than 25,500 individual TRI and PCS records of point
source pollutant releases of 111 different chemicals. Approximately 1,020 individual wa-
tersheds and 31 distinct industrial categories are represented. In general, areas that are
population centers and are associated with industrial activity receive the greatest amount of
potential sediment contaminants from point sources. Direct releases of potential sediment
contaminants from 4,869 facilities in PCS totaled nearly 19 million Ib/yr in 1994. From
1993 TRI data, direct releases and transfers to POTWs of potential sediment contaminants
IX
-------
Executivfe Summary
from 3,432 manufacturing facilities totaled 7.3 million Ib/yr. The inventory is limited by
the quality, quantity, coverage, and bias of the release data in TRI and PCS.
EPA developed and employed a screening-level load analysis procedure to achieve the
objectives of this study. The "Load Score" is a unitless index of the magnitude of potential
sediment contamination based on chemical/facility-specific releases, physical and chemical prop-
erties, and potential environmental risk. The loading analysis is limited by the lack of consider-
ation of site-specific information, the lack of pollutant transport analysis, and the uncertainty
associated with the components of the chemical-specific sediment hazard scores. For these
reasons, the results of the loading analysis should be used for screening purposes only, not as a
definitive judgment regarding the most significant sediment contaminants, the most affected
watersheds, or the most important industrial categories.
This analysis indicates that metals and organic chemicals that can cause or contribute
to contamination of sediment continue to be released from point sources. Although impor-
tant in some instances, releases of PAHs, pesticides, and PCBs appear to be less prevalent
than releases of metals and other organic compounds. The loading analysis relies on cor-
relative, statistically based threshold values to evaluate the potential adverse effects of met-
als in sediment. Although these correlative thresholds are useful, they are limited in their
application because they do not directly address the bioavailability of metals in sediment.
This report further emphasizes the need for the development of practical assessment tools to
evaluate the bioavailability and toxicity of metals in sediment.
The data analysis based on release data from TRI and PCS indicates that certain indus-
trial categories have a high potential for contributing to sediment contamination. Sewerage
systems, with nearly 2,000 facilities in PCS, represent more than one-half of the total Load
Score of all the data analyzed in PCS and TRI together. Sixty-one percent of the Load
Score for sewerage systems is from the five divalent metals. The Metal Products and Fin-
ishing, Primary Metal Industries, and Industrial Organic Chemicals categories were ranked
in the top five industrial categories in terms of Load Score for both PCS and TRI. Other
industrial categories ranked in the top five for either TRI or PCS include Public Utilities
(other than sewerage systems), Petroleum Refining, and Other Chemical Product's. Al-
though TRI and PCS contain extensive records from most of the large dischargers, these
data represent a limited, and somewhat biased, segment of the overall discharger commu-
nity. Some industrial categories are not well represented in either PCS or TRI. Thus, these
results reflect data availability as much as relative sediment hazard potential.
Total Load Scores at the watershed level ranged from 0 to 312. Of the 1,020 water-
sheds evaluated, 17 watersheds were placed in priority group 1 (Load Score greater than
80), 19 watersheds were placed in priority group 2 (Load Score range 61-80), 29 water-
sheds were placed in priority group 3 (Load Score range 41-60), 87 watersheds were placed
in priority group 4 (Load Score range 21-40), and 672 watersheds were placed in priority
group 5 (Load Score range 1-20). One hundred ninety-six watersheds had a Load Score of
zero and were not assigned to a priority group. Figure ES-1 shows the location of water-
sheds in priority groups 1,2,3, and 4.
The watersheds identified in this analysis represent areas where sediment contami-
nants are discharged; they do not necessarily represent locations where sediment contami-
nation has occurred or will occur. As defined by the U.S. Geological Survey 8-digit cataloging
unit, watersheds can represent large areas that vary greatly in size, shape, and physical/

characteristics encompassing large mainstem rivers and small tributary streams. Transport,
sediment partitioning, and sediment accumulationwhether in locations very close to the
point of discharge or far downstreamdepend on many factors, including streamflow, stream
velocity, geomorphology, particle size distribution, organic carbon content, suspended sedi-
ment load, temperature, pH, and salinity. However, comparison with existing sediment moni-
toring data provides further means of screening watersheds where point sources are more
likely to contribute to contamination.
The general relationship between annual point source releases and results reported in Vol-
ume 1: National Sediment Quality Survey demonstrates a co-occurrence of active discharges of
sediment contaminants and evidence of sediment contamination. A watershed with a high Load
Score is more likely to contain one of the 96 areas of probable concern for sediment contamina-
tion (APCs) in the National Sediment Quality Survey. For priority group 1,75 percent of the
watersheds contain APCs. For priority groups 2 and 3, 37 and 35 percent of the watersheds
contain APCs, respectively. For priority group 4,21 percent of the watersheds contain APCs.
Finally, for priority group 5, 8 percent of the watersheds contain APCs. Less than 1 percent of
the watersheds with a zero Load Score contain APCs.
While this analysis does not imply that point sources caused the in-place contamina-
tion, it emphasizes the potential significance of contaminant releases in areas already con-
taminated. There are many sources of sediment contaminants in watersheds, both active and
historical, point and nonpoint. This assessment identifies specific watersheds where active
point sources might play an important role. To promote natural recovery of contaminated
areas, active dischargers must be adequately controlled to ensure that their releases do not
perpetuate contamination problems.
The draft EPA report Environmental Goals for America With Milestones for 2005
(USEPA, 1996a) proposes that the Agency, together with its state partners, adequately con-
trol point sources of contamination over the next 10 years in 10 percent of the watersheds
where sediment contamination is widespread. Specifically, major facility discharge limits
need to be evaluated and appropriately revised in watersheds at greatest risk from active
discharges. The objective of these evaluations should be to determine whether existing tech-
nology-based controls or water quality-based discharge limits protect downstream sediment
quality to the degree necessary for natural recovery of contaminated sites. EPA is currently
developing the methodology to relate point source contributions to sediment contaminant
concentrations. This methodology is needed before developing permit limits protective of
sediment quality. This report identifies 29 watersheds that both contain APCs based on the
National Sediment Quality Survey and are in Load Score priority group 1,2, or 3 based on
this analysis. These watersheds should be considered for further evaluation and necessary
action to achieve the milestone in EPA's Goals Report.

Chapter 1
Introduction
D:ring the past two decades, the U.S. Environmental Protection Agency (EPA) has
ocused its water pollution control efforts on protecting water quality within the
/ater column. This has been accomplished primarily by controlling municipal and
industrial point sources. More recently, EPA has begun to direct its efforts toward identify-
ing and controlling other threats to the aquatic environment, including the accumulation of
toxic chemicals in sediment. Because many different Agency program offices are involved
in addressing the nationwide problem of contaminated sediments, EPA established an Agency-
wide steering committee in 1989 to oversee the development of a Contaminated Sediment
Management Strategy (CSMS). The purpose of the proposed CSMS is to coordinate the
Agency's efforts to assess, prevent, and remediate contaminated sediment that poses envi-
ronmental and human health risks.
The Water Resources Development Act of 1992 (WRDA) directed EPA, in consulta-
tion with the National Oceanic and Atmospheric Administration and the Army Corps of
Engineers, to conduct a comprehensive national survey of data regarding aquatic sediment
quality in the United States. The Act required EPA to compile all existing information on
the quantity, chemical and physical composition, and geographic location of pollutants in
aquatic sediment, including the probable source of such pollutants and identification of
those sediments which are contaminated. The Act further required EPA to report to the
Congress the findings, conclusions, and recommendations of such survey, including rec-
ommendations for actions necessary to prevent contamination of aquatic sediments and to
control sources of contamination. Volume 3 of this report (this volume) addresses point
sources. Volume 4 of this report, when completed, will address nonpoint sources. Chapter
4 of Volume 1 of this report describes all probable source categories.
EPA's Office of Science and Technology (OST) initiated work several years ago on the
development of a Nationalsediment Inventory (NSI) through a series of pilot inventories,
planning meetings, and national workshops. Recently, various data indicative of sediment
quality have been compiled into an integrated data set. The evaluation of the sediment
quality data was documented in Volume 1: National Sediment Quality Survey (hereafter
referred to as the Survey), The Survey evaluation serves as a means of screening and
targeting, and it identifies 96 watersheds containing areas of probable concern for sediment
contamination (APCs). OST's Survey and the Office of Policy, Planning, and Evaluation's
(OPPE's) draft National Goals Report both call for further evaluation of these watersheds.
Further evaluation entails performing additional site characterization based on sediment
chemistry and related biological data, determining temporal and spatial trends, assessing
human health and ecological risks, identifying potential sources of sediment contamination,
and determining whether potential sources are adequately controlled. The end result of these
efforts should be a judgment whether natural recovery is a feasible option for risk reduction.
To proceed with the identification of potential sources of sediment contaminants, OST
initiated two related efforts to identify, characterize, and evaluate the potential importance
of nonpoint and point source discharges of pollutants that might contribute to sediment

of nonpoint and point source discharges of pollutants that might contribute to sediment
contamination. The nonpoint source assessment effort focuses on collecting information
on contributions primarily from agricultural lands, inactive and abandoned mine sites, ur-
ban areas, and atmospheric deposition. The corresponding effort to assess active point
source releases and to identify watersheds where such releases might contribute to sedi-
ment contamination is the focus of this volume.
OST is leading EPA's efforts to complete a National Sediment Contaminant Point Source
Inventory. Collection and analysis of data describing sources of contaminated sediment
will help provide an understanding of the potential magnitude and extent of contamination
problems in the Nation's freshwater and estuarine sediments. The inventory will be useful
to help locate potentially contaminated sites for additional monitoring and to integrate
sediment sampling into existing water quality monitoring programs. The Point Source
Inventory will also be a useful source of information for identifying pollution prevention
opportunities and other source control efforts.
Objectives of Point Source Inventory and Analysis
Identifying, locating, and assessing all potential sources of sediment contamination on
a nationwide basis is a major undertaking. Potentially significant sources of sediment
contamination include municipal sewage treatment facilities, storm water discharges and
combined sewer overflows, urban and agricultural runoff, industrial discharges of process
wastewater, leachate from hazardous waste sites, and atmospheric deposition from point
and mobile source emissions. Industrial dischargers that are no longer active, poor-quality
effluent in years prior to effective treatment, and spills are important historical sources of
existing sediment contamination that are difficult to identify. The Point Source Inventory
is a compilation of the most recent available documented releases of known sediment con-
taminants from active municipal, industrial, and federal facilities. The major objectives of
this inventory and the analysis presented in this report are as follows:
Generate a relative ranking of chemicals and industrial categories based on 1993
Toxic Release Inventory (TRI) and 1994 Permit Compliance System (PCS) chemi-
cal release data.
Prioritize watersheds for collection of additional information that might lead to the
identification of additional monitoring needs or pollution prevention opportuni-
ties.
Establish a baseline to which additional or future inventories can be compared.
Chapter 2 of this report describes the data sources used to develop the Point Source
Inventory. Chapter 3 describes the data sources, assumptions, and algorithms used to de-
velop the screening-level chemical load scores. Chapter 4 presents a summary of the re-
sults in relationship to chemicals and chemical classes, watersheds, and industrial categories.
Appendix A contains the data used to develop chemical load scores for individual chemi-
cals. Appendix B presents the results of the watershed priority groupings, and Appendix C
includes detailed results of the analysis by industrial category.

Anticipated Uses
EPA's proposed Contaminated Sediment Management Strategy (CSMS) calls for the
Agency to compile data, perform analyses, and develop tools that will allow integration of
sediment contamination concerns into existing EPA program office activities, including:
Targeting further evaluations
Evaluating alternative control options
Enhancing current assessment approaches
Evaluating environmental benefits.
This evaluation has identified watersheds where point sources could contribute to sedi-
ment contamination. It is anticipated that states, in cooperation with EPA and other federal
agencies, will proceed with further evaluations of the top-priority watersheds. This effort is
especially important for those watersheds also identified from the Survey as containing
areas of probable concern for sediment contamination (APCs). The purpose of additional
evaluation should be to determine whether existing technology-based controls or water qual-
ity-based discharge limits adequately protect downstream sediment quality and do not com-
promise natural recovery of contaminated areas.
The sediment contaminant loading analysis described in this report is currently the most
comprehensive assessment of national point source releases of sediment contaminants. The
Load Score analysis and data compiled for this report can be powerful tools for water re-
source managers at the national, regional, state, and watershed levels. This report provides
a wealth of information that can be integrated with other data characterizing the quality of
aquatic sediment and other contaminant sources. For example, point source release data
and analysis results could be incorporated into the Agency's recently developed PC-based
geographic information system (GIS) for watershed modeling and assessment. This system,
called BASINS (Better Assessment Science for Integrating Point and Nonpoint Sources),
provides the framework to integrate and analyze spatially related data, such as land use,
stream hydrography, ambient contaminant levels in water and sediment, and discharger lo-
cations and release amounts.: This system also allows the user to augment or replace data
with additional or more appropriate information at the regional or local level. This is an
important feature when contemplating use of PCS or TRI data, which cover a limited seg-
ment of all dischargers and might contain erroneous data, for specific local analyses.
The Point Source Inventory can be used to track risk reduction achieved through re-
duced surface water loadings. This supports activities such as the EPA Office of Policy,
Planning, and Evaluation's National Goals Report, which is an effort to develop and track
progress toward the Clean Water Act and other environmental legislation goals. Although
not a direct measure of environmental quality, the Point Source Inventory provides a mecha-
nism to track discharges of sediment contaminants.

Chapter 2
Development of the
Point Source Inventory
fTlhe methodology employed in developing the Point Source Inventory had three basic
I steps. First, a master list of chemicals of interest was compiled. The chemicals
A selected were those with available sediment chemistry screening values that were
used to evaluate Survey data. These chemicals are frequently detected in sediment and
have been studied for their potential adverse effects on aquatic life or human health. Sec-
ond, annual loading amounts were determined for the chemicals of interest. Two EPA
computer databases were used as the primary sources of release information: the Toxic
Release Inventory (TRI) and the Permit Compliance System (PCS). Releases were then
assigned to watersheds, chemical classes, and industrial categories.
Identification of Point Source Releases of
Sediment Contaminants
For the Survey, EPA compiled sediment chemistry and fish tissue residue data for more
than 230 chemicals whose detected levels in these media could be evaluated for potential
adverse effects to aquatic 'life or human health. The Survey evaluation of potential adverse
effects to aquatic life was based on comparing sediment chemistry measurements to levels
associated with adverse effects. The evaluation of adverse human health effects was based
on comparing direct fish tissue measures, or predicted levels based on sediment concentra-
tions, to EPA risk levels or Food and Drug Administration (FDA) guidance. Evaluating
the potential threat to sediment quality posed by a point source chemical release requires
knowledge of the level in sediment associated with an adverse effect. EPA could not evalu-
ate sediment chemistry measurements for approximately 100 of the more than 230 chemi-
cals because the Agency lacked either information regarding adverse effects to aquatic life
or the means to predict fish tissue concentrations resulting from exposures to sediment
contaminant concentrations (i.e., a biota-sediment accumulation factor (BSAF), available
for nonionic organic compounds only). Other chemicals lacked the necessary information
to evaluate the chemicalfate or intermedia partitioning upon discharge to surface water.
These factors limited the inventory to 111 individual sediment contaminants.
The data requirements of the Point Source Inventory limited the number of useful
databases containing information about the release of those 111 chemicals from point sources.
The requirements include (1) classification of the type of discharger (industrial category or
Standard Industrial Classification [SIC] code); (2) pollutant-specific release data (e.g., mea-
sured or estimated load tp the environment in mass per time) for individual facilities; and
(3) location information for pollutant releases. TRI and PCS are the only national data-
bases that meet these data requirements.
2-1
-------
Development of" the Point Source Inventory
Toxic Release Inventory (TRI). TRI is a consistent, comprehensive national database
of toxic chemical releases to all environmental media. Congress mandated its creation to
fulfill the community right-to-know provision (section 313) of Title in of the Superfund
Amendments and Reauthorization Act of 1986 (SARA). This section requires the owner/
operator of an industrial facility to report environmental releases of more than 300 speci-
fied toxic chemicals to EPA if the facility meets certain criteria. EPA's Office of Pollution
Prevention and Toxics (OPPT) manages the information on releases submitted by industry.
Reports submitted by industry are the sole source of data in TRI. TRI contains release
information from approximately 27,000 facilities. An owner/operator must file a report for
a facility when it meets the following criteria:
It employs the equivalent of 10 or more full-time employees.
It engages in manufacturing (SIC Codes 20 through 39).
It manufactures, imports, or processes more than 25,000 pounds of any listed
chemical, or otherwise uses more than 10,000 pounds of any listed chemical.
For each listed chemical (currently over 300 specific chemicals and 20 chemical groups),
the facility must submit a "Toxic Chemical Release Reporting Form," which contains the
following:
Facility identification information such as facility name, parent company, loca-
tion (street address and latitude/longitude), type of business (based on SIC codes),
key identifiers (such as Dun and Bradstreet ID, and NPDES numbers), and name
of receiving water body.
Offsite transfer locations for toxic chemicals, such as publicly owned treatment
works (name and address of POTW) or waste disposal and treatment facilities
(name, address, and EPA identification number).
Chemical-specific information such as chemical identification (name and Chemi-
cal Abstract Service [CAS] number); use of the chemical at the facility; quanti-
ties released to air (fugitive and stack), water (including storm water), under-
ground injection, and land; quantities transferred to offsite locations; and waste
treatment methods and efficiencies. The quantities are reported either as a range
for levels below 1,000 Ib/year (i.e., 0-10, 11-499, and 500-999) or as a total an-
nual release. The facility also reports the methods used in determining the re-
lease quantities (e.g., actual monitoring data, mass balance calculations, or emis-
sion factors).
Permit Compliance System (PCS). PCS is the national information management sys-
tem for tracking compliance, enforcement, and permit status for the National Pollutant
Discharge Elimination System (NPDES) program under the Clean Water Act. The NPDES
program requires permits for all point source pollutant discharges to navigable U.S. water-
ways (other than dredged or fill material regulated under section 404 of the Clean Water
Act). Specific discharge limits or monitoring requirements have been set for over 200
individual chemicals.
2-2
-------
National StedimentContammant Point Source jliiventory
EPA's Office of Wastewater Management oversees the NPDES program on a national
level. EPA has authorized 43 states and the Virgin Islands to administer the NPDES pro-
gram. EPA regional offices administer the program in nonauthorized states. More than
65,000 active NPDES permits have been issued to facilities throughout the Nation. PCS
has extensive records on approximately 7,000 permits that are classified as "major." Fa-
cilities are classified as "major" based on consideration of many factors, including effluent
design flow, physical and chemical characteristics of the waste stream, and location of
discharge. Each permit record in PCS may contain information that:
Identifies and describes the facility (including a primary SIC code) to which the
permit has been issued.
Specifies the pollutant discharge limits for that facility.
Records the actual amounts of pollutants and flows measured in the facility's
wastewater discharges.
Tracks the facility's history of compliance with construction requirements, pol-
lutant limits, and reporting requirements.
Major facilities must report compliance with NPDES permit limits, usually on a monthly
basis, via Discharge Monitoring Reports (DMRs). DMRs provide detailed information on
measured concentrations, including those which are in violation of established limits for
the permit. DMR data entered into PCS include the type of violation (if any), concentra-
tion and quantity values, and monitoring period. The PCS database is updated twice weekly.
Determination of Chemical Loads
The Point Source Inventory consists of two distinct sets of chemical loading data: one
based on TRI records and one based on PCS records. For this evaluation, data from TRI
and PCS were extracted for the calendar years 1993 and 1994, respectively. Together, TRI
and PCS form the most comprehensive national chemical loading database. Facilities cov-
ered by both TRI and PCS cannot be readily identified, however, because no common,
quality-controlled facility identification data elements are available in these databases. TRI
contains a field for NPDES number, but its quality control is poor. Both TRI and PCS
contain a field for EPA identification number, but these numbers, too, are unreliable. There-
fore, there is a potential for double records of releases for chemicals reported in both TRI
and PCS. As a result, the data in TRI and PCS are evaluated independently.
Toxic Release Inventory Data
For each TRI facility, total amounts of the chemicals of interest reported to be dis-
charged to surface water and POTWs in calendar year 1993 were retrieved. For each
chemical, the total release to surface water and an adjusted release to POTWs were summed
to yield a total facility discharge. Some characteristics of the TRI database might introduce
uncertainty into the release estimates. For example, manufacturers required to report to
TRI might estimate chemical releases using ranges (e.g., 10 to 499 Ib/yr). In the TRI
database, the ranges are converted to a single value represented by the midpoint of the
range (e.g., 250 Ib/yr). Use of these midpoint values may overestimate or underestimate
the actual releases of TRI chemicals.
2-3
-------
Development of the Point Source Inventory
The reported amounts of releases to POTWs were adjusted by assuming that typical
secondary treatments, such as activated sludge and aeration lagoons, remove a portion of
the chemical load. Review of chemical-specific data from the Office of Research and
Development's Treatability Database (USEPA, 1991) indicated that removal rates can be
highly variable and dependent on conditions at the POTW. Based on peer review com-
ments received on a draft version of this methodology (Adams, 1994), all pollutants were
assigned a removal rate of 75 percent. This removal rate does not tend to significantly
overestimate or underestimate actual loading values. In a secondary treatment system,
such as an activated sludge system, chemicals that are readily biodegraded are usually, but
not always, removed at rates equal to or in excess of 90 percent, and adsorption often
removes 80 to 85 percent of the mass of chemicals that do not biodegrade (Adams, 1994).
Permit Compliance System Data
It is important to recognize that, unlike TRI, PCS is a permit tracking system, not a
repository of pollutant release amounts. However, an option in PCS called Effluent Data
Statistics (EDS) can process PCS data to calculate loading values (USEPA, 1992a). EDS
uses the following hierarchy to assign a loading for each pollutant: (1) reported chemical
mass loading and (2) chemical loadings estimated based on discharge flow and concentra-
tion measurement. Depending on the monitoring requirements imposed by the permit,
concentrations may be reported in many different ways. EDS selects concentration mea-
surements from PCS in the following order of preference for inclusion in the inventory:
Average concentration
Maximum concentration
Minimum concentration.
Loadings were estimated only for records with valid concentrations (as defined by
EDS) and corresponding flow data assuming 30 operating days per month for each facility.
Loadings were estimated using the following general equation:
Load = Flow * Cone * Conversion Factors Equation 1
where:
load = specific pollutant load from a facility per unit time;
flow = facility effluent flow per unit time;
cone = concentration of a pollutant; and
conversion factors = appropriate factors to convert reported units to standard units.
Total release amounts of the chemicals of interest were calculated for each PCS facil-
ity. Data were retrieved at the discharge pipe level from PCS for every NPDES discharger
where the requisite data were available. Concentration data for each chemical were con-
verted into annual loadings using Equation 1 above. The calculated loads for a given
chemical from each discharge pipe at a facility were summed to yield the total facility load.
In addition, multiple parameters sometimes exist for the same pollutant. For example, zinc
concentrations might be reported as total zinc and dissolved zinc. In these cases, the larg-
2-4

est calculated load (usually the "total" load) was selected for inclusion in the Point Source
Inventory.
Concentration measurements for the chemicals of interest are often recorded in PCS as
below the detection limit. In some cases, these measurements might reflect a low chemical
concentration that available analytical instrumentation cannot recognize. In other cases,
the chemical might not be present in the effluent. Measurements reported below a detec-
tion limit most commonly occur for highly toxic pollutants. Monitoring requirements for
these chemicals might exist as a "safeguard" to alert managers to the presence of a particu-
lar chemical in effluent, or might be part of a large set of chemical measurements required
by an effluent guideline rule covering a particular industrial category. In any case, a mea-
surement reported below detection in PCS monitoring data does not establish the presence
of the chemical in effluent. Therefore, values below the detection limit are set to zero in
this inventory.
Assignment of Geographic Location and
Industrial Category
Stream reach numbers (from EPA River Reach File 1) were assigned to each facility in
the Point Source Inventory to place chemical discharges into watersheds. Because the
reach number was frequently missing from both PCS and TRI, reach numbers were added
electronically by linking PCS and TRI facility identification codes to the EPA Industrial
Facilities Discharge File (IFD). If the reach number was not available in IFD, a computer-
ized routine that starts with the facility latitude/longitude and searches the EPA Reach File
for the nearest reach, up to a maximum distance of 10 miles, was employed. If the facility
latitude and longitude coordinates were missing, the centroid of the county was used as the
discharge location. '
Industrial categories are groupings based on SIC codes. An industrial category can be
based on a single 4-digit SIC code (e.g., Petroleum Refining) or a large and variable range
of SIC codes (e.g., Metal Products and Finishing). Each facility in the Point Source Inven-
tory was assigned a single SIC code based on the designated primary SIC code in PCS and
TRI. However, because many large industrial facilities are involved in multiple activities
that could correspond to different SIC codes, industrial category groupings are only ap-
proximate. There were 31 industrial categories overall. PCS data were grouped into 27
industrial categories, and TRI data were grouped into 21 industrial categories.
Inventory Limitations
The Point Source Inventory contains various limitations that should be considered when
using this information in environmental decision-making. These limitations do not, how-
ever, preclude its use as a targeting tool to prioritize watersheds, chemicals, and industries
for further evaluation. In some instances, the limitations might affect small-scale analyses
(i.e., individual stream or lake water body segments) while large-scale analyses, such as
the ones presented in this report, are affected to a lesser degree. Conclusions presented in
this report are made with consideration of the following factors.
This analysis is primarily limited by the quality and quantity of existing data in na-
tional EPA databases. The broad scope of the inventory has prohibited collection of large
amounts of data from numerous site-specific information sources at this time. Therefore,
2-5
-------
Development of the Point Source Inventory
the inventory relies on data available in national electronic databases such as TRI and PCS.
Although a considerable volume of information is contained in these databases, many im-
portant parameters are not available. In particular, no national electronic database accu-
rately, consistently, or completely stores information concerning the characteristics of
water bodies, such as underlying sediment type. Furthermore, data quality assurance/qual-
ity control is an important issue when using data from large national databases that receive
input from a variety of sources. The amount of data contained hi these national databases
is too large to conduct comprehensive verification procedures. In addition, it should be
noted that the number of facilities discharging chemicals of interest may vary from year to
year based on such factors as regulatory changes (e.g., increased chemical reporting or SIC
coverage in TRI, or increases in the number of recorded storm water permits in PCS) or
economic conditions. Given these qualifications, the three major limitations of the inven-
tory as it is now structured are:
The inability to predict whether a point source release could contribute to a sedi-
ment contamination problem.
The inability to predict where point source releases might contribute to sediment
contamination (i.e., the geographic analyses are limited to identifying areas or
watersheds where point source releases occur).
The inability to assess contributions from nonpoint source inputs (including de-
liberate introduction of toxic substances, such as pesticides and household chemi-
cals, to the environment) and from point source inputs not represented in the PCS
or TRI databases (e.g., facilities that do not meet a TRI reporting criterion and for
which NPDES permits do not require monthly monitoring).
Conclusions based on the Point Source Inventory should take into consideration the
inherent limitations of the databases and the assumptions used in developing the inventory.
Factors associated with database limitations that should be considered include the possibil-
ity of erroneous data in TRI and PCS, the limited coverage of TRI and PCS, and inherent
database biases. Neither PCS nor TRI accurately reflects the full extent of toxic chemical
releases from point sources, and the data contained in both may be inherently biased. Al-
though several hundred individual chemicals are represented in each database, as many as
5 to 10 times more chemicals might be discharged (Adams, 1994). In addition, the number
of chemicals addressed in PCS permits is highly variable. Because the types and number
of chemicals included are partly a function of the policies and practices of the state or
regional permitting authority, and of the industrial activities conducted at the facility, the
data might be biased toward some geographic regions and industrial categories. Further-
more, only approximately 10 percent of permitted dischargers are classified as "major" and
have extensive records from which chemical loads can be derived. Facilities subject to
TRI reporting represent a relatively narrow range of commercial activities (manufacturing
only). Although the TRI database is based on a standard set of chemicals, many highly
toxic chemicals that tend to accumulate in sediment are not included. Therefore, TRI
captures only a portion of chemical releases to the environment. Future enhancements to
TRI might overcome some of these limitations and the biases they create.
Other potential sources of error are associated with the assumptions used in the assign-
ment of geographic location and industrial category. In many cases, geographic location
assignment was made using latitude and longitude coordinates of the facility and the near-
2-6

est stream reach. However, the nearest stream might not be the receiving stream for some
facilities. Also, for TRI data, POTW receiving streams could not be identified. Conse-
quently, chemical loadings derived from POTW transfers for TRI data were assigned to the
stream reach associated with the reporting facility. Industrial category assignment was
made on the basis of primary SIC code; however, many facilities are engaged in a wide
range of commercial activities. As a result, chemical wastes generated from non-primary
SIC code activities are included with those from the primary SIC code in the Point Source
Inventory.

Chapter 3
Development of Chemical
Load Scores
a; major objective of the Point Source Inventory was to develop and employ a
reening-level loading analysis procedure to identify and prioritize watersheds where
;tive point sources may contribute to sediment contamination, and to generate a
relative ranking of chemicals and industrial source categories that are potential contribu-
tors. To enable screening-level analyses, chemical-specific chemical loading scores (CLSs)
were developed and used to normalize the annual chemical loads (ACLs) in the Point
Source Inventory. In the screening-level analysis (described in Section 4), ACLs were
multiplied by chemical-specific CLSs to produce adjusted loads:
Adjusted Load = CLS * ACL
Equation 2
where:
CLS = Chemical load score, a product of the FATE and TOX scores as
described below, and
ACL = Annual chemical load, the annual release amount (Ib/yr) of a specific
chemical from individual industrial or municipal treatment facilities.
CLSs are intended to represent both the potential of a particular chemical to accumu-
late in sediment upon discharge to surface water (independent of the characteristics of the
site) and the potential ecological and human health risk posed by the chemical. The CLS is
the product of the chemical-specific toxicity (TOX) score and chemical-specific fate (FATE)
score. The TOX score is intended to represent the potential for adverse effects to human
health and aquatic life from chemicals in sediment. The FATE score is intended to repre-
sent the potential for a chemical to partition to and persist in sediment. Four previous
works were examined to assjst in the development of the screening-level methodology:
National Sediment Quality Survey (peer-reviewed draft, USEPA, 1996b);
Established methods of determining sediment toxicity (USEPA, 1992b);
Superfund's Hazard Ranking System, Final Rule (USEPA, 1990a); and
NOAA's pesticide hazard rating system (Pait et al., 1992).
Calculated CLSs, TOX scores, and FATE scores, along with the information required to
calculate them (i.e., sediment chemistry screening values and physical/chemical proper-
ties), are presented in Appendix A of this report.

-------
Development of Chemical Load Scores
The adjusted load computed for a facility's discharge of a specific chemical is assigned
a Load Score. The Load Score is a unitless index of the magnitude of potential sediment
contamination based on chemical/facility-specific releases, physical and chemical proper-
ties, and potential environmental risk. The mathematical relationship of adjusted load
scores to Load Score is given by the folio whig equation:
Load Score = INT (login (adjusted load)) + 1
Equation 3
Values less than zero or greater than 5 are set to zero and 5, respectively. Load Scores
indicate the potential contribution to sediment contamination in the absence of any knowl-
edge of historical or nonpoint source inputs and site-specific conditions (e.g., stream ve-
locity, organic carbon content of underlying sediment) affecting chemical fate and intermedia
partitioning. Load Scores may be used to rank and compare potential sediment contamina-
tion sources. Once the Load Scores were calculated for each chemical-facility combina-
tion, a number of data aggregations were performed to evaluate chemical classes and
industrial categories for their relative potential risk of causing sediment contamination,
and to identify watersheds where the risk of contamination from active point sources might
be the greatest.
Table 3-1 illustrates the assignment of Load Scores. In general, the Load Score repre-
sents the magnitude of the adjusted load (product of CLS times ACL). However, if the
adjusted load is less than 1, the release is assigned a Load Score of zero. This assumes that
these releases are not significant potential contributors to sediment contamination, and is
intended to focus attention on larger releases with greater hazard potential. The column
headings of Table 3-1 provide chemicals representative of each CLS range as a reference.
For example, the sediment hazard posed by mercury is approximately 10 times the hazard
posed by pyrene. This scoring system allows comparison of annual loads of chemicals that
vary in their hazard potential. For example, an annual load of 1,000 pounds of zinc is
approximately equivalent to an annual load of 100 pounds of fluorene or 10 pounds of

also be summed across aggregate units. For example, 20 facilities each releasing 100
pounds of mercury per year (Load Score = 4) in a given watershed would yield a watershed
Load Score of 80 (20 times 4).
Chemical-Specific Toxicity Score
Sediment contamination is a function of the mixture and concentration of toxic pollut-
ants in the sediment and the physical and chemical characteristics of the site. To assess
potential sediment toxicity, sediment chemistry data must be related to adverse biological
effects. Numerical effects-based, chemical-specific sediment chemistry screening values
have been used to assist analysts and managers in the evaluation of sediment chemistry
data and to identify and prioritize problem areas (Di Toro et al., 1991). The TOX score is
one component of the CLS. This chemical-specific value was calculated by taking the
inverse of the chemical's derived sediment chemistry screening value reported in milli-
grams per kilogram (mg/kg). Because the inverse of the sediment chemistry screening
value is used, the TOX score increases in direct proportion to the toxicity of the chemical.
Several methods are currently available for developing sediment quality screening val-
ues (USEPA, 1992b). Most of these methods require information on site-specific condi-
tions (field data) and chemical-specific properties. However, because field data are not
available for each point source discharge location, screening values for use in this analysis
must be based on empirical methods that make use of available data from a variety of sites,
or mechanistic methods where the site-specific components can be reasonably assumed.
The NOAA National Status and Trends program's effects range approach and the State of
Washington's apparent effect threshold approach use existing sediment chemistry and bio-
logical effects data from a variety of sites, and EPA's equilibrium partitioning approach has
a site-specific component that can be reasonably assumed. The preferred approach for
screening value estimation depends on the properties and expected chemical partitioning
associated with the released chemical.
In this study, a combination of the equilibrium partitioning (EqP) approach and bio-
logical effects correlation approaches was used to estimate sediment chemistry screening
values for the protection of aquatic life. The theoretical bioaccumulation (TBP) approach
was used to estimate sediment chemistry screening values for human health assessments.
Appendix A contains a listing of all the calculated sediment chemistry screening values for
the chemicals of interest contained in the Point Source Inventory.
It is important to note that the certainty with which sediment toxicity can be predicted
for each chemical varies significantly based on the quality of the available data and the
appropriateness of exposure assumptions. Estimated sediment chemistry screening values
are to be used for screening purposes only. Their purpose is to obtain a relative ranking of
potential hazard for aquatic bottom sediments from point source pollutant discharges to
surface waters. The following limitations of the estimated sediment chemistry screening
values should be noted:
Values may be overprotective or underprotective of actual site-specific sediment
because methodological and exposure conditions vary considerably.
3-3
-------
Development of Chemical Load Scojrcs
Values are general approximations of concentrations potentially leading to ad-
verse effects because data and assessment methods are continually being com-
piled and developed.
Values are based on a composite of several different sediment assessment ap-
proaches and a variety of data sources, the application of which EPA has not
adopted or endorsed for use outside this and other screening-level analyses.
EPA has proposed sediment quality criteria (SQCs) for five chemicals based on exten-
sive data quality and quantity requirements and methodologies that have gone through
extensive peer review. The other estimated sediment chemistry screening values for addi-
tional chemicals presented in Appendix A of this report do not represent proposed SQCs.
The sediment chemistry screening values were developed or compiled for the evaluation of
Survey data (Volume 1 of this report). The remainder of this section provides a brief
overview of the screening values. The interested reader should consult Volume 1 of this
report and appendices for detailed descriptions and explanations.
Aquatic Life Screening Values
The sediment chemistry screening values used to evaluate potential adverse effects to
aquatic life include theoretically and empirically based values. The theoretically based
values rely on demonstrated laboratory toxicity and physical/chemical properties of sedi-
ment to predict a concentration level that protects the benthic community from chronic
adverse reproductive or growth effects. The empirically based, or correlative, threshold
values rely on paired field and laboratory data to relate incidence of observed adverse
biological effects to the dry-weight sediment concentration of a specific chemical.
The theoretically based screening values, limited to nonionic organic compounds, in-
clude the following parameters:
Sediment Quality Criteria (SQCs): EPA (1993a, b, c, d, e) has developed draft
SQCs for five chemicals using the equilibrium partitioning (EqP) approach, which
involves predicting a dry-weight sediment concentration that is in equilibrium
with a threshold pore water concentration using the chemical-specific organic
carbon/water partition coefficient (K(x.) and the site-specific organic carbon con-
tent. The EqP approach is described in detail in Appendix B of the Survey. Draft
SQCs are based on the highest-quality data available, which have been reviewed
extensively.
Sediment Quality Advisory Levels (SQALs): SQALs were also developed us-
ing the EqP approach, but have fewer aquatic toxicity data requirements.
For purposes of calculating sediment hazard scores for the chemicals with available
SQCs and SQALs, a default organic carbon content of 1 percent was used because of lack
of site-specific sediment information in PCS and TRI. In practical application, the organic
carbon content can vary a great deal, as can important other binding phases at any given
sampling station.
The empirically based, correlative approaches used for the Point Source Inventory in-
clude the following upper screening values. Each of these parameters has a corresponding
lower (more stringent) screening value that was not used in the development of TOX scores

for a chemical-specific loading analysis such as this. As previously stated, the inverse of
the sediment chemistry screening value serves as the TOX score to produce a positive
relationship between screening values and TOX scores. In other words, the more stringent
the screening value, the greater the TOX score.
Chemical-Specific Fate Score
The second component of the Chemical Load Score (CLS) is the FATE score. The
FATE score is the product of the air/water partitioning subfactor (HLC score), sediment
adsorption subfactor (KOC score), and biodegradation subfactor (BIODEG score). The
potential for a chemical to accumulate in the underlying sediment upon discharge to sur-
face water depends greatly on site-specific characteristics such as sediment organic matter
content, temperature, suspended particulate matter, and the lotic or lentic nature of the
receiving water body. The physical/chemical properties of the pollutants also affect their
transport and persistence in the aquatic environment. The chemicals of interest in the Point
Source Inventory differ widely in their physical/chemical properties. Some chemicals are
very likely to partition to and to persist in the sediment, some will likely volatilize, and
others will rapidly degrade. Therefore, a FATE score with sediment adsorption, air/water
partitioning, and aqueous degradation subfactors was used. Three physical/chemical prop-
erties for organic sediment contaminants were obtained for the chemicals in the inventory:
the sediment adsorption coefficient or K(K, the Henry's Law constant (HLC), and the aero-
bic aqueous biodegradation half-life.
The two transport subfactors, air-water partitioning and sediment adsorption, are rep-
resented by chemical-specific HLC and K^, values, respectively. These subfactors were
treated in a manner similar to that used in the pesticide hazard rating system devised by Pait
et al. (1992). Individual HLC and K^. values were assigned scores ranging from 0.1 to 1.
These values were then multiplied to produce a score that represents the likelihood of
transport to the sediment.
The aqueous degradation subfactor is represented by chemical-specific aerobic bio-
degradation half-lives. Because the sediment hazard score was applied to annual release
amounts, the half-life was converted to an annual loss rate constant and multiplied by the
transport value (i.e., the product of the two transport subfactor scores) to arrive at the final
FATE score.
Air-Water Partitioning Subfactor
The Henry's Law constant (HLC) is the ratio of vapor pressure to solubility and is
indicative of the propensity of a chemical to volatilize from surface water (Lyman et al.,
1982). The larger the HLC, the more likely the chemical will volatilize. Lyman et al.
(1982) state that a chemical with an HLC less than 3 x 10'7 (atm-mVmole) is essentially
nonvolatile, and a chemical with an HLC greater than 10'3 (atm-mVmole) will volatilize
rapidly from surface water. HLC scores were calculated according to the following steps:

scores across the range of values:

Sediment Adsorption Subfactor
KX= is a chemical-specific adsorption parameter that is largely independent of the prop-
erties of soil or sediment and can be used as a relative indicator of adsorption to such
media. Although a high K^, value indicates that a chemical is more likely to partition to
sediment, it also indicates ;that a chemical may be less bioavailable. K^ is highly inversely
correlated with solubility and fairly well correlated with BSAF. °°
U.S. EPA (1993b) recommends using the following regression equation to calculate
the organic carbon-water partition coefficient (K ) from the octanol-water partition coeffi-
cient (Kow):
loglvKoc = 0.00028 + 0.983 * logwKm
Equation 5
Where available, K^ values were calculated from the latest EPA-recommended octanol-
water coefficient (Kow) (Karickhoff and Long, 1995). Other Kow values used included those
derived from the slow-stir flask method, which were selected preferentially over other labo-
ratory values reported in literature (USEPA, 1993f).

Aqueous Biodegradation Subfactor
Although many physical and chemical processes can contribute to degradation (e.g.,
hydrolysis, photolysis, biological degradation), aerobic biodegradation half-life was se-
lected as the sole indicator of environmental persistence of a chemical released to the water
column. Ignoring other removal mechanisms is a conservative approach because it can
only overestimate rather than underestimate a chemical's persistence potential. Aerobic
aqueous biodegradation half-lives are empirically derived time periods when half of a chemi-
cal load released to water is degraded by microbial action in the presence of oxygen. Al-
though the degradation products may be equal in toxicity to or even more toxic than the
parent, evaluation of chemical metabolites was not considered in the hazard analysis. Aero-
bic biodegradation half-lives for the current set of potential sediment contaminants range
from 4 hours to 16 years.
Half-lives in days were converted to loss rate constants in (years)'1 using the following
equation:

Because other factors, such as deep burial, might become important over time, chemi-
cals with reported half-lives greater than 7 years were assigned a half-life of 7 years. This
results in the largest BIODEG score of 10. The BIODEG score was calculated by taking

the inverse of the loss rate constant so that more persistent compounds would have higher
values:

Equation 8
The FATE score was calculated by combining the HLC, KOC, and BIODEG scores
according the following formula:
FATEscore =(BIODEGSCOJ * (HLCSCOJ * (KOCSCOJ Equation 9
Metals, which will not degrade or volatilize, were assigned a BIODEG score of 10 and
an HLC score of 1. The relative partitioning of dissolved metal between the water column
and the underlying sediment is a function of site-specific conditions, not inherent proper-
ties of the metal. Therefore, metals were assigned a KOC score of 0.5, representing the
midpoint of all possible values.

The function of the sediment chemistry screening value in the CLS is to increase or
decrease the adjusted load relative to the annual chemical load (ACL) based on the toxicity
exhibited by the chemical. Ignoring the effects of the FATE score components, a chemical
with a sediment chemistry screening value less than 1 mg/kg has an CLS greater than 1 and
higher adjusted loads than ACLs. On the other hand, a chemical with a sediment chemistry
screening value greater than 1 mg/kg has an CLS less than 1 and lower adjusted loads than

-------
Development of Chemical Load Scores
ACLs. The magnitude of the effect on the adjusted load is in direct proportion to the
magnitude of the sediment chemistry screening value versus a value of 1 mg/kg. The
"standard" of 1 mg/kg is arbitrary and does not have any physical or biochemical signifi-
cance.
The function of the BIODEG score is to adjust the ACL based on a chemical's persis-
tence in the aquatic environment. Half-life values in days were converted to a loss rate
constant in (years)'1. The BIODEG score, which is the inverse annual loss rate constant,
has the mathematical effect of converting an annual surface water load to a steady-state
mass of chemical in the water column. Chemicals with a half-life greater than 253 days
(ln(2) * 365 days/yr) have a BIODEG score greater than 1, which increases the adjusted
load. This indicates that the steady-state mass is greater than the annual load (i.e., net
accumulation). Conversely, chemicals with a half-life less than 253 days have a BIODEG
score less than 1, which decreases the adjusted load. This indicates that the steady-state
mass is less than the annual load (i.e., net loss). The magnitude of the effect on adjusted
load is in direct proportion to the magnitude of the half-life versus a value of 253.
The functions of the KOC score and HLC score are to decrease the adjusted load de-
pending on the chemical's propensity to partition to sediment or volatilize from the water
column. If a chemical is hydrophilic and has little propensity to bind to sediment, the
adjusted load will decrease by as much as one order of magnitude. Likewise, if a chemical
has a strong tendency to volatilize, the adjusted load will also decrease by as much as one
order of magnitude. This relatively small adjustment was made because of the many miti-
gating site-specific factors that affect intermedia partitioning.
The sediment chemistry screening values and ACLs for the chemicals of concern in
this analysis vary over more orders of magnitude than do biodegrcdation half-lives, KOC
scores, and HLC scores. Therefore, adjusted loads are primarily driven by ACLs and chemi-
cal toxicity.
The sensitivity of the parameters used in CLS calculation, with the exception of K ,,
are depicted in Figure 3-1. Note that the x-axis labels represent l.he factor by which the
original values are multiplied (i.e., the effect of doubling a given parameter on the CLS is
read from the point labeled "2" on the x-axis). Likewise, the y-axis labels represent the
change in CLS values resulting from altering input parameters. For example, if the per-
cent OC is halved ("0.5" on the x-axis), the CLS would be doubled ("2" on the y-axis).
The sensitivity of K^ is depicted in Figure 3-2 in three parts: one for the effect based on
KOC score (increase in K^. means greater propensity to partition to sediment and higher
CLS), one for the effect based on the equilibrium partitioning approach (increase in K
means less bioavailability and lower CLS), and one for the overall K^ effect.
The overall uncertainty in the CLS precludes their use in analyses that require a high
degree of accuracy. However, this level of uncertainty is acceptable for meeting the objec-
tive of performing a screening-level loading analysis.

Results of Screening-
Level Analyses
The screening-level loading analysis of Point Source Inventory data from the 1993
Toxic Release Inventory (TRI) and the 1994 Permit Compliance System (PCS) can
be used to evaluate the release of sediment contaminants and to identify the chemical
classes, watersheds, and industrial categories that may be associated with potential sediment
quality problems arising from point sources. The analysis does not necessarily indicate
where contaminated sediment problems have occurred or who is responsible. Further infor-
mation to screen watersheds can be obtained when the release data are compared to the
Survey data evaluation (Volume 1 of this report).
This chapter describes how the Point Source Inventory data were prepared for the load-
ing analysis and highlights the results by chemical, watershed, and industrial category. Tables
and figures of summary information are presented within the body of the text. Longer tables
that contain more detailed information are presented in Appendices B and C. Appendix B
contains a listing of watersheds (defined by 8-digit U.S. Geological Survey (USGS) catalog-
ing units) grouped by specific ranges of Load Scores. These groups are referred to as
priority groups in this report. Appendix C contains detailed information on chemicals asso-
ciated with the industrial categories evaluated in this analysis.
Preparation of Data for Loading Analysis
The first step in conducting the screening-level loading analysis was to qualitatively
examine the Point Source Inventory data for validity and prepare the data for analysis. Of
the original 233 potential sediment contaminants analyzed as part of the Survey, 122 were
excluded from the loading analysis because a CLS could not be calculated or no data were
available for analysis. Table Al in Appendix A contains a complete list of the remaining
111 sediment contaminants participating in the loading analysis.
Although the PCS and TRI data were not systematically checked for errors when the
inventory was developed, an attempt was made to eliminate highly suspect records from the
loading analysis. Several loading records from PCS were excluded from the loading analy-
sis because they were highly suspect and would bias the results. For this analysis, EPA
defined a highly suspect record as the release of any chemical in excess of one-half million
pounds per year. While feasible at large municipal treatment works such as Chicago Main
or Blue Plains in Washington, DC, experience in examining PCS records indicates that these
extremely large surface water releases can be traced back to incorrectly reported concentra-
tion or flow measurements. Because incorrect flow measurements would have an impact on
all loadings reported for that facility, all data for 21 facilities from PCS were removed from
further analysis. Based on examining monitoring data reported for dioxin in PCS, all dioxin
data were also excluded from the analysis. Many dioxin records were listed as below detec-

tion, and thus treated as zero discharge. EPA had little confidence in the remaining detect-
able levels because of problems with measurement units and other concerns. No facilities
from TRI were removed from the analysis.
More than 25,500 individual records of direct or indirect pollutant releases to surface
water from point sources were examined in the screening-level loading analysis for their
potential to contribute to sediment contamination. Releases of 111 different chemicals in-
cluding divalent metals (i.e., cadmium, copper, lead, nickel, and zinc); mercury; other met-
als; polynuclear aromatic hydrocarbons (PAHs); pesticides; polychlorinated biphenyls (PCBs);
and other organic compounds were analyzed. The 1993 TRI data have release records for
60 of these chemicals, and the 1994 PCS data have release records for 108 of these chemi-
cals.
PCS records show that direct releases of sediment contaminants from 4,869 facilities
totaled nearly 19 million Ib/yr in 1994. Based on 1993 TRI data, direct releases and trans-
fers to POTWs (multiplied by 0.25 to account for removal during treatment) from 3,432
manufacturing facilities totaled 7.3 million Ib/yr. Facilities with chemical release records in
PCS and/or TRI were located in all 50 states, the District of Columbia, Puerto Rico, and the
Virgin Islands. Over 1,000 individual watersheds, as defined by USGS 8-digit cataloging
units, receive loads of potential sediment contaminants as reported by PCS and TRI. This
corresponds to approximately one-half of all watersheds in the United States. Individual
facilities are placed into 31 distinct industrial categories. These categories represent a broad
range of activities (e.g., POTWs, chemical manufacturers, textile mills, coal mines).
Analysis by Chemical
Table 4-1 presents the annual release, adjusted load, and Load Score for each of the 60
chemicals included in the loading analysis for TRI data. The CLS and the number of facili-
ties reporting surface water releases or POTW transfers for each chemical are also included
in Table 4-1. Based on TRI data, xylene, nickel, and copper have the largest aggregate Load
Scores. Together with the next seven chemicals listed in Table 4-1 (lead, toluene, phenol,
chromium, 1,1,1-trichloroethane, trichloromethane, and benzene), all with Load Scores greater
than 80, the top 10 chemicals represent more than 69 percent of the aggregate Load Score
for data from TRI.
Table 4-2 shows the corresponding information for the 108 chemicals included in the
loading analysis for PCS data. Based on PCS data, zinc, copper, and nickel have the largest
aggregate Load Scores. Together with the next 10 chemicals listed in Table 4-2 (cadmium,
silver, mercury, lead, chromium, arsenic, PCBs, benzo(a)pyrene, antimony, and
tetrachloroethene), all with Load Scores greater than 80, the top 13 represent more than 86
percent of the aggregate Load Score for data from PCS.
Several chemicals have large aggregate national raw loads and are released from a large
number of facilities (i.e., zinc and copper), whereas other chemicals (e.g., chlordane) appear
to represent a few isolated releases. Tables 4-1 and 4-2 also present the distribution of
records by Load Score. The Load Score distribution is skewed to the right for most chemi-
cals. That is, most records indicate a low Load Score (i.e., less than 3); substantially fewer
records have large Load Scores. This assessment transforms the adjusted load for each
analyzed record to a Load Score from zero to five representing the magnitude of the CLS *
ACL product. This approach minimizes the impact of a small number of very large release
records that account for the majority of adjusted load and appropriately focuses attention on

National pediment Contamination Point Source Inventory
chemicals with a large number of potentially significant releases. The results for the DDT
metabolite DDE illustrates this point. The adjusted load is very large, yet appears to be
caused by a single release record. Although not ignoring the potential local importance of
this individual release, the total Load Score reflects the overall national significance of point
source DDE discharge.
Aggregate raw loads and Load Scores for individual chemicals are grouped by chemical
class to determine which types of chemicals cause the greatest potential sediment hazard.
Chemical classes are assigned in the following manner:
Divalent Metal: This group comprises five metal species (cadmium, copper, nickel,
lead, and zinc) that are typically associated with acid-volatile sulfide (AVS). These
metals have sulfide solubilities smaller than that of iron sulfide, making them less
bioavailable as long as the AVS molar concentration (reservoir of sulfide anions in
anoxic sediment) exceeds the sum of the molar concentrations of the simultaneously
extracted metals. '
Mercury: Mercury also has a sulfide solubility less than that of iron sulfide; however,
mercury was not included with the other AVS metals because of the complicating
factors of methylatioh in sediment and subsequent bioaccumulation. Unfortunately,
the sediment chemistry screening value does not account for the effects of this
bioaccumulation potential.
Other Metal: This group includes the remaining metals evaluated: antimony, arsenic,
chromium, and silver,
Pesticide: This group includes chemicals that are usually large, complex, and manu-
factured to be biological inhibitors.
Polynuclear Aromatic Hydrocarbon (PAH): This group includes all polynuclear
aromatic hydrocarbons, including those which are halogenated.
Polychlorinated Biphenyl (PCB): This group includes all measured PCBs whether
reported as total PCBs or as one of seven aroclors. PCBs are highly toxic, highly
bioaccumulative, and highly persistent.
Other Organic: This;group includes the remaining organic chemicals not classified as
pesticides, PAHs, or PCBs.
Table 4-3 depicts raw loads, adjusted load, and Load Scores by chemical class for TRI
data. The TRI data show that other organic and divalent metal categories represent about 95
and 4 percent of the annual release, respectively. These same categories represent 54 and 36
percent of the Load Score. 'Metals (antimony, arsenic, chromium, and silver) account for 6
percent of the Load Score while less than 1 percent of the annual release. All other chemical
groups account for less than 3 percent of the total Load Score for TRI data. Table 4-4
depicts raw loads, adjusted loads, and Load Scores by chemical class for PCS data. In
contrast to the TRI data, divalent metals dominate the raw load and Load Score for PCS.
The PCS data show that the divalent metal, other organic, and other metal categories repre-
sent 80, 10, and 10 percent of the annual release, respectively. These same categories rep-
resent 60, 7, and 16 percent of the Load Score. Mercury also contributes 7 percent to the
aggregate Load Score. Contributions to the Load Score from pesticides, PAHs-, and PCBs
range from 3 to 5 percent. :

Analysis by Watershed
To evaluate watersheds, Load Scores are grouped by USGS hydrologic unit codes.
The 8-digit hydrologic unit code is one of several ways to define a watershed, and it repre-
sents four levels of organization. The first two digits represent the region. USGS divides
the contiguous United States into 18 distinct hydrologic regions based on river drainage.
Alaska, Hawaii, and the Caribbean are regions 19,20, and 21, respectively. Each region is
divided into as many as 30 subregions, but typically regions contain approximately 10
subregions. Subregions are represented by the first 4 digits in the 8-digit code. Subregions
can be further subdivided into as many as four accounting units, represented by the first 6
digits of the 8-digit code. Accounting units, in turn, can be subdivided into as many as 10
cataloging units, represented by the full 8-digit code. For the purposes of this study, Load
Scores are summed according to USGS cataloging units (8-digit code). There are more
than 2,100 cataloging units (watersheds) in the United States.
Based on the data from TRI and PCS, a total Load Score was computed for 733 and 861
watersheds, respectively. For watersheds represented by both TRI and PCS the higher of the
two scores was applied. This approach resulted in a total Load Score for 1,020 watersheds.
Selecting the maximum Load Score, rather than adding the results, eliminates problems asso-

elated with double-counting releases; however, this approach may underestimate total releases
and the "true" Load Score. Total Load Scores at the watershed level ranged from 0 to 312,
although few were above 100, To divide individual watersheds into groups based on releases
of sediment contaminants, EPA simply created quintiles within the 0 to 100 range. Watersheds
with a total Load Score from 81 to 100 were assigned to priority group 1, or the first quintile.
All watersheds with total Load Scores greater than 100 were also placed in the first quintile.
Priority group 2 watersheds have a Load Score of 61 to 80. Priority group 3 watersheds have
a Load Score of 41 to 60, and priority group 4 watersheds have a Load Score from 21 to 40.
Priority group 5 watersheds have a Load Score from 1 to 20. Watersheds with no data or a
Load Score of zero were not assigned to a priority group. Figure 4-1 presents the watersheds
in the contiguous United States based on Load Score for priority groups 1 through 4.
Table 4-5 summarizes this information for each EPA region. The majority of priority
group 1, 2, and 3 watersheds are in EPA Regions 2 and 5. Of the 1,020 watersheds evalu-
ated, 17 watersheds were placed in priority group 1, 19 watersheds were placed in priority
group 2,29 watersheds were placed in priority group 3,87 watersheds were placed in prior-
ity group 4, and 672 watersheds were placed in priority group 5. The remaining 196 water-
sheds had a Load Score of zero and were not assigned to a priority group. Appendix B
contains a detailed table listing all of the 824 watersheds assigned to the 5 priority groups
and includes information on the predominant chemical class and predominant industrial
category associated with that chemical class. The following is a list of the 17 watersheds

The general relationship between annual point source releases and results of the Survey
evaluation demonstrate a co-occurrence of active discharge of sediment contaminants and
evidence of sediment contamination. Figure 4-2 depicts this relationship by plotting the
percent of monitoring stations with a high (Tier 1) or intermediate (Tier 2) probability of
contamination in a watershed, as ascribed in the Survey, versus the watershed Load Score.
Only those watersheds with at least one Tier 1 or Tier 2 station from the Survey evaluation
and a Load Score above zero are plotted. In watersheds with Load Scores greater than 50,

at least 70 percent of all monitoring stations within the watershed exhibit some degree of
contamination. Watersheds with relatively low Load Scores vary greatly in the extent of
contamination, demonstrating the importance of contaminant sources not documented in this
study, such as historical releases and nonpoint sources.
Watersheds with high Load Scores are more likely to contain areas of probable concern
for sediment contamination (APCs) in the Survey evaluation. In Figure 4-2, watersheds
containing APCs are plotted as dark circles, whereas all other watersheds are plotted as
cross marks. Overall, approximately 10 percent of watersheds receiving point source dis-
charges contain APCs. However, it is apparent that the fraction of watersheds containing
APCs increases as the Load Score increases. In fact, watersheds containing APCs consti-
tute 75 percent (12 of 16) of priority group 1 watersheds. Figure 4-3 further illustrates this
relationship. For priority groups 2 and 3, 37 and 35 percent of the watersheds contain
APCs, respectively. For priority group 4,21 percent of the watersheds contain APCs. For
priority group 5, only 8 percent of the watersheds contain APCs. Less than 1 percent of the
watersheds with a Load Score of zero contain APCs.
While this analysis does not imply that point sources caused the in-place contamination,
it emphasizes the potential significance of contaminant releases in areas already contami-
nated. There are many sources of sediment contaminants in watersheds, both active and
historical, point and nonpoint. This assessment identifies specific watersheds where active
point sources might play an important role. To promote natural recovery of contaminated
areas, active dischargers must be adequately controlled to ensure that their releases do not
perpetuate contamination problems.
Analysis by Industrial Category
Facility-level Load Scores for chemical releases were summed by industrial categories,
as assigned based on the primary SIC code reported in PCS or TRI. There are 31 industrial
categories overall, covering a broad range of activities. Table 4-6 lists these industrial
categories by descending Load Score for TRI data. Table 4-7 presents the same information
for PCS data. For TRI data; metal products and finishing, primary metal industries, petro-
leum refining, and industrial organic chemicals account for 67 percent of the Load Score.
For PCS data, sewerage systems (i.e., POTWs), other public utilities, metal products and

finishing, and industrial organic chemicals account for 80 percent of the Load Score. POTWs
alone account for 62 percent of the Load Score. It should be noted that public utilities
include steam electric power generators, and EPA did not attempt to account for pollutants
in the intake water used by the industry. For PCS, the dominant industrial categories are
also the ones required to perform the most monitoring. Thus, these results reflect data
availability as much as relative sediment hazard potential. Only five TRI facilities, but a
significant number of PCS facilities (198), do not fall into the defined industrial categories
or do not report a primary SIC code. These facilities are listed as "Nonclassifiable."
Tables Cl and C2 in Appendix C present Load Scores grouped by chemical for each
industrial category for TRI and PCS, respectively. The number of facilities within the
industrial category discharging each chemical, the raw load (Ib/yr), and adjusted load are
also presented. These tables are not comprehensive lists of all chemicals discharged from all
facilities, but are limited to industrial category-chemical combinations where the Load Scores
exceed 0. Tables 4-6 and 4-7 also present the number of facilities in each industrial cat-
egory. Most of the PCS facilities (38 percent) included in the loading analysis are POTWs,
with other public utilities, other trade and services, metal products and finishing, and pri-
mary metal industries also well represented.
Most of the TRI facilities (44 percent) are metal products and finishing operations.
Primary metal industries, industrial organic chemicals, and other chemical products repre-
sent another 14,7, and 6 percent of the represented facilities, respectively. Some industrial
categories are not well represented in either PCS or TRI. This limited representation could
be a result of many facilities within the industry not qualifying for major NPDES permits
(which require monthly discharge monitoring for specific chemicals), not meeting the re-
porting requirements for TRI, or not having release records for pollutants retained in the
loading analysis.

Conclusions
EPA conducted the screening-level sediment loading analysis of the Point Source In-
ventory data to obtain more information about potential sediment contamination and its
sources, and to prioritize chemicals, watersheds, and industries for further evaluation. The
inventory is limited by the quality, quantity, coverage, and bias of the release data in TRI
and PCS. The loading analysis is limited by the lack of consideration of site-specific
information, the lack of pollutant transport analysis, and the uncertainty associated with
the components of the chemical-specific chemical load scores. For these reasons, the
results should be used for screening purposes only, not as a definitive judgment regarding
the most significant sediment contaminants, the most affected watersheds, or the most
important industrial categories.
This study indicates that point source releases of sediment contaminants to surface
water are ongoing and, in many cases, coincident with areas where there is evidence of
contamination. TRI and PCS contain records of approximately 25,500 individual point

source releases of 111 different sediment contaminants into over 1,000 watersheds across
the country from 31 distinct industrial categories. Direct releases from 4,869 facilities in
PCS totaled nearly 19 million pounds per year in 1994. Based on 1993 TRI data, direct
releases and transfers to POTWs (multiplied by 0.25 to account for removal during treat-
ment) from 3,432 manufacturing facilities totaled 7.3 million Ib/yr. Assuming that there is
some overlap between TRI and PCS, these databases together indicate that major munici-
pal and industrial facilities release about 20-25 million pounds of sediment contaminants
annually.

Results'of Screening-Level Analyses
This analysis indicates that metals and organic chemicals other than pesticides, PAHs,
and PCBs constitute the most extensive potential sediment hazard from point sources.
Although important in some instances, releases of PAHs, pesticides, and PCBs appear to
be less prevalent. Survey evaluation results (Volume 1) indicate that other organic chemi-
cals, as a class of pollutants, are not as significant as other classes. The potential sediment
hazard posed by metals represents the most substantial area of agreement between the Point
Source Inventory loading assessment and the Survey evaluation, on both an individual chemi-
cal basis and a watershed basis. The Point Source Inventory and Survey both rely on
correlative, statistically based threshold values to evaluate the potential adverse effects of
metals in sediment. Although these correlative thresholds are useful, they are limited in their
application because they do not directly address the bioavailability of metals in sediment.
This report further emphasizes the need for the development of practical assessment tools to
evaluate the bioavailability and toxicity of metals in sediment.
The watersheds identified in this analysis represent areas where sediment contami-
nants are discharged; they do not necessarily represent locations where sediment contami-
nation has occurred or will occur. Watersheds, as defined by the USGS 8-digit cataloging
unit, can represent large areas encompassing large mainstem rivers and small tributary
streams that vary greatly in size, shape, and physical/chemical characteristics. Transport,
sediment partitioning, and sediment accumulationwhether in locations very close to the
point of discharge or far downstreamdepend on many factors, including streamflow,
stream velocity, geomorphology, particle size distribution, organic carbon content, sus-
pended sediment load, temperature, pH, and salinity. However, comparison with existing
sediment monitoring data provides further means of screening watersheds where point
sources are more likely to contribute to contamination.
A watershed with a high Load Score is more likely to contain one of the 96 areas of
probable concern for sediment contamination (APCs) in the Survey evaluation. The
draft EPA report Environmental Goals for America With Milestones for 2005 (USEPA,
1996a) proposes that the Agency, together with its state partners, adequately control
point sources of contamination over the next 10 years in 10 percent of the watersheds
where sediment contamination is of probable concern. Specifically, major facility dis-
charge limits need to be evaluated and appropriately revised in watersheds at greatest
risk from active discharges. The objective of these evaluations should be to determine
whether existing technology-based controls or water quality-based discharge limits protect
downstream sediment quality to the degree necessary for natural recovery of contami-
nated sites. EPA is currently developing the methodology to relate point source contri-
butions to sediment contaminant concentrations. This methodology is needed before
developing permit limits protective of sediment quality. This report identifies 29 water-
sheds that both contain APCs from the Survey and are in Load Score priority group 1, 2,
or 3 from this analysis. These watersheds should be considered for further evaluation
and necessary action to achieve the milestone in EPA's Goals Report.
