 Dear Colleague:
       The U.S. Environmental Protection  Agency is pleased  to transmit  the final version of
 the EPA  document  titled National Sediment Contaminant Point Source Inventory: Analysis of
 Release Data for 1992, The primary goal of this document is  to provide  information
 concerning  point source releases of potential  sediment contaminants.

       The Water Resources  Development  Act of 1992 and EPA's Contaminated  Sediment
 Management  Strategy call for a national  inventory and evaluation  of sediment  quality to
 help determine  the extent,  severity, and sources  of sediment contamination.  In response,
 EPA  initiated the National  Sediment  Inventory (NSI). The NSI is comprised of three
 components: a site inventory  of monitoring and testing data, a point source inventory of
 chemical  releases, and a nonpoint  source inventory  of chemical releases.  This document
 describes  the compilation of discharge data and  analysis  of the relative potential  sediment
 hazard from large municipal,  industrial, and Federal  facilities.  The study concludes that
 point source dischargers release chemicals that may accumulate  in sediment  and cause
 adverse effects.  Furthermore,  certain chemicals, geographic areas, and industrial categories
 appear to exhibit greater  potential  for association with sediment contamination  than others.
 However, the document  emphasizes the uncertainty  and  limitations of the hazard analysis.

       EPA anticipates  that this study, in conjunction  with the other NSI  components and
 additional  sources of information,  will assist government  agencies  and other involved parties
 in effectively assessing and  managing  sediment quality.  Please mail, call, FAX, or Email

                            EXECUTIVE SUMMARY

       In the Water Resources Development Act (WRDA) of 1992, Congress mandated that the
U.S. Environmental Protection Agency (EPA) develop an inventory of sediment quality and
pollutant source information, and evaluate this information to  identify the nature and extent,
including causes, of sediment contamination in the United States. WRDA also required that this
information be reported to Congress in 1994 and every two years thereafter.  In addition, EPA's
proposed Contaminated Sediment  Management Strategy calls for  the development of this
database, termed the National Sediment Inventory (NSI), and describes how more than twenty
EPA Program Offices and Regions will use this information to help assess, manage, and prevent
contaminated sediment problems nationwide. The National Sediment Contaminant Point Source
Inventory (NSCSI) is one component of the NSI; the other two components are the National
Sediment Contaminant Site Inventory and the National Sediment Contaminant Nonpoint Source
Inventory.  Information from all three databases (continually updated and improved over time)
will be used in the biennial Reports to Congress.

       The objectives of the NSCSI project were to: (1) develop the Sediment Contaminant Point
Source Inventory,  a national data base of point source pollutant discharges from municipal,
Federal, and industrial point sources that may result  in sediment contamination, and (2)   to
analyze these releases using a screening-level hazard analysis procedure that ranks chemicals,
geographic   areas,  and  industries  of  concern  based  on  the  potential  to cause  sediment
contamination.

       The first step in  the development of the Point Source Inventory database was to compile
a comprehensive set of potential point source sediment  contaminants by  matching a list  of
chemicals monitored and found in sediments with those released from point sources.  Two EPA
databases, the Toxics Release Inventory (TRI) and the Permit Compliance System (PCS), were
then used to create two data sets of chemical release information, geographic  locations, and
industrial categories for the thousands of facilities releasing these chemicals nationwide. The
geographic location of each facility was linked to the Reach File in EPA's STORET database
based on latitude and longitude, and all facilities were assigned SIC codes  corresponding to a
consistent set of industrial categories.

       The hazard analysis is based on weighting chemical release amounts by their relative
potential sediment contamination hazard, as indicated by human and aquatic life toxicity test data
                                          IX

-------
and physical/chemical fate properties.  Unitless relative hazard-weighted release (HAZREL)
scores were developed for each chemical by multiplying chemical loads derived from PCS and
TRI data by a chemical-specific sediment hazard score (SHS).  Sediment hazard scores are based
on aquatic life and human health biological effects factors (TOX score) and fate factors (FATE
score).  TOX scores result from estimated sediment chemistry screening values developed for
the sole purpose of this analysis.  The FATE score is intended to represent the potential for a
particular chemical to accumulate in sediment upon release into the water column.  HAZREL
scores were used to sort the data according to the chemicals, geographic areas,  and industries
of greatest  potential concern.

      The NSCSI database and analyses are limited by the coverage and biases of the chemical
release data sources, the  quality and quantity of chemical  release data available from these
sources, the lack of precision in geographical location and industrial category assignment, and
the uncertainties associated with chemical-specific toxicity and fate data and potential  adverse
effects assessment methods.  For example,  data  from PCS will be  biased toward highly
controlled industries which must monitor for numerous compounds, and TRI data will be biased
toward  industries  required to report under EPCRA section 313 (e.g., manufacturing).   In
addition, the hazard analysis cannot predict whether a point source release will cause a sediment
contamination problem:   it can only demonstrate the relative potential in comparison  to other
chemicals, geographic areas, or industrial categories in the absence of any mitigating site-specific
information (e.g., organic carbon content).  However, this  study indicates that ongoing point
source discharges of chemicals that have the potential to accumulate  in sediment and cause
adverse effects are occurring. Furthermore, certain chemicals, geographic areas, and industrial
categories appear to exhibit greater potential to be associated with sediment contamination than
others.

       Over 22,000 individual TRI and PCS records of point source pollutant releases of 118
different chemicals are included in the  hazard analysis for the year 1992,  Approximately 930
individual watersheds and 46 distinct industrial categories are represented. When combined, TRI
data and PCS data (setting values below detection limit equal to half the detection limit),  indicate
that over 16 million kilograms of potential sediment contaminants were estimated to be  released
in 1992. The total combined HAZREL score for these releases is 5.1 million.  TRI data alone
account for approximately 8 percent of the combined TRI-PCS releases, and approximately 3
percent of the combined TRI-PCS HAZREL score.  In 1992, direct releases from 2,584 facilities
classified as a major permittee in PCS ranged from 14 million kilograms per year (KGY) (values

-------
below detection limits set equal to zero) to 16.7 million KGY (values below detection were set
equal to the full detection limit). From 1992 TRI data, direct releases and transfers to POTWs
(multiplied by 0.25 to account for removal during treatment) from 3,218 manufacturing facilities
totalled  1.3 million  KGY.   The results indicate that  for TRI  data, halogenated  organic
compounds and pesticides  have the  highest HAZREL scores among chemical classes.  The
individual TRI chemicals with the highest HAZREL scores  are: hexachlorobenzene; ethylene
dibromide; chlordane;  1,2-dichloropropane; and  anthracene.  PCS data alone account for
approximately 92 percent of the combined TRI-PCS releases, and approximately 97 percent of
the combined  TRI-PCS HAZREL score.   For PCS data, pesticides, halogenated  organic
compounds, and metals have the highest HAZREL scores among chemical classes. Toxaphene,
hexachlorobenzene, and silver are the highest ranked chemicals among these groups.

      In general,  areas that are population centers and are  associated with industrial activity
receive  the greatest amount of potential sediment contaminants  from point sources.  The
geographic regions, defined by United States Geological Survey (USGS) hydrologic regions,
receiving the greatest amount of hazard-weighted point source releases in 1992 are the Lower
Mississippi, the Great Lakes, and the South Atlantic Gulf (river drainage basins from southern
Virginia to eastern Mississippi that flow into the Atlantic Ocean or the Gulf of Mexico), based
on TRI  data.  These three hydrologic regions  account for nearly 85 percent of the total TRI
HAZREL score for the  United States. The California, Mid-Atlantic, Lower Mississippi, Great
Lakes, and Texas-Gulf hydrologic regions have the highest HAZREL scores, based on PCS data.
The HAZREL scores for these five regions account for nearly 85 percent of the total HAZREL
score for the United States, based on PCS data. At the hydrologic region level, the distribution
of combined TRI-PCS HAZREL scores differs only slightly from the distribution based on PCS
HAZREL scores alone because  PCS release data and HAZREL score accounts for the vast
majority of combined  TRI-PCS releases (92 percent)  and HAZREL score (97 percent).
However, at smaller units of aggregation, such as USGS cataloging units (or watersheds), the
combined TRI-PCS data provide the most comprehensive  set of sediment contaminant  release
information. Based on combined TRI-PCS data, over one-quarter (26 percent) of the watersheds
with the highest HAZREL scores in the Nation  (i.e., the  upper  20 percent, designated as
"priority group 1") are located in  EPA Region 4.   Large proportions of priority group  1
watersheds are also located in Region 6 (17 percent), Region  5 (16 percent), Region 2 (11
percent), and Regions 9 and 3(10 percent each). Large HAZREL scores are obtained from both
PCS data and TRI data  for river drainage areas in the Mid-Atlantic coast, Southern Piedmont,
Gulf coast, Great Lakes, Ohio Valley, California coast, and northwest Washington State.  It is
                                         XI

-------
noteworthy that nonpoint sources may also be significant contributors to sediment contamination
in these areas.

       The industries  of greatest concern in the nation, based on TRI data,  are  inorganic
chemical producers, petroleum refineries, and organic chemical manufacturers. Together, these
three  industries account for over three quarters of the  total  TRI HAZREL score.   Other
significant industrial categories based on TRI data are photographic equipment (4 percent of TRI
HAZREL score), pulp and paper (3 percent of TRI HAZREL score), and pesticides (3 percent
of TRI HAZREL score). Based on PCS data using half detection limit values, releases from
POTWs account for approximately 61 percent of the total PCS HAZREL score. Other industrial
categories of greatest concern on a national scale include organic chemical  manufacturers (11
percent of PCS HAZREL score), pulp and paper (3 percent of PCS HAZREL score), and metal
products and machinery (2 percent of PCS HAZREL score).  Based on PCS data using zero
rather than one-half the detection limit for values recorded as below the detection limit, releases
from  POTWs account  for approximately 49 percent of the total  PCS HAZREL score,  and
organic chemical manufacturers, pulp and paper, and metal products and machinery account for
approximately 26  percent, 8  percent,  and  7  percent  of the total   PCS  HAZREL  score,
respectively.  As with the analysis by geographic region, the distribution of combined TRI-PCS
HAZREL scores among industrial categories differs only slightly from the distribution based on
PCS HAZREL scores alone because PCS release data and HAZREL score accounts for the vast
majority of combined TRI-PCS releases and HAZREL score.  The top industrial categories in
the  nation are usually also among the top industries in EPA Regions.   However, the top
industrial categories in individual States often differ from the highest ranked national industries,
and may reflect dominant industrial activities in those States.

       It is  important to note  that aggregate data  from the Point Source Inventory may not
necessarily be indicative of actual conditions within a geographic area or industry. For example,
a large regional HAZREL score for a chemical may be the result of large releases from a small
number of facilities. This may indicate a localized problem, but not a broad regional problem.
Alternatively, a large regional  total could be the result of multiple releases distributed evenly
throughout a region but are not indicative of a significantly high level  at any one location.  It
is also important to recognize that calculated HAZREL scores are only indicative of the relative
potential for sediment contamination from documented point source inputs in the absence of any
knowledge of historical or nonpoint  source  inputs and  site-specific conditions (e.g., stream
velocity, organic carbon content of underlying sediment) affecting chemical fate and inter-media
                                          XII

partitioning.  Actual releases of toxic chemicals and resulting impacts to human health and the
environment may be greater or less than those predicted in this study depending on the reliability
of the PCS or TRJ data, the contributions of contaminants from unidentified point and nonpoint
sources, and the environmental conditions of the site.

       Despite  these  limitations,  the  comprehensive  compilation  of  available  sediment
contaminant release data in the Point  Source  Inventory, along  with  the  pollutant-specific
sediment hazard scores, serve as a useful targeting tool to prioritize geographic areas, chemicals
and  industries  for  further evaluation.   Point Source  Inventory data  grouped  by industrial
category, and further grouped by chemical within industrial category, can assist EPA's Office
of Science  and  Technology (OST) in screening industries for effluent guidelines development.
Point Source Inventory data is also being used by  the Office of Enforcement to identify potential
discharges  or industrial activities that may be contributing to fish advisories. In addition, State
or EPA Regional NPDES permitting authorities could potentially incorporate  Point Source
Inventory data in the initial stages of reissuing permits and establishing monitoring requirements.
Finally, the Point Source Inventory  is intended  to be a companion to the National Sediment
Inventory of contaminated sites. The data from the Point Source Inventory, when combined with
data from the Site Inventory, provide a valuable tool for screening facilities and  industries, as
well as chemicals, that  may be contributing to sediment contamination, and identifying locations
for further  sediment testing.

1.0.    INTRODUCTION

       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 towards identifying 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 CSMS is to coordinate the Agency's efforts to  assess,  prevent, and remediate
contaminated sediment that poses environmental and human health  risks.

       Integral to  the CSMS  is the  identification of chemicals  of concern  based on each
chemical's inherent toxicity, persistence, and propensity to accumulate in sediment; the sources
of these chemicals; and the  geographic areas most heavily impacted by their release.  The EPA
Office of Science and  Technology (OST)  is  leading EPA's effort 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
Point Source Inventory will be  useful to help target potentially contaminated sites for additional
monitoring and to integrate sediment sampling into existing water quality monitoring programs.
The  inventory will also be a useful source of information for targeting pollution prevention
opportunities and other source control efforts, planning and implementing successful remediation
projects, and as a component  of  a  "weight of evidence" approach to prioritizing possible
enforcement actions in areas known to be problematic.

1.1.    Point Source Inventory and Analysis Objectives

       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, stormwater 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
                                          1-1

-------
to effective treatment/prevention initiatives, and spills are important historical sources of existing
sediment contamination that are difficult to identify. The Point Source Inventory is a compilation
of documented releases of known sediment contaminants from active municipal, industrial, and
Federal facilities  in the calendar year 1992.  The major objectives  of this inventory and  the
analysis presented in this report are to:

       •       Generate a relative ranking of chemicals and industrial source categories based on
              1992 Toxic  Release Inventory (TRI)  and Permit Compliance  System  (PCS)
              chemical release data;

       •       Demonstrate the extent of and characterize regional  differences  in  loading of
              potential sediment contaminants;

       •       Prioritize watersheds for collection of additional information that may lead to the
              identification of additional monitoring needs;

       •       Describe how  this  information  can  be  useful  for contaminated sediment
              monitoring, prevention, and cleanup program activities; and

       •       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 develop
the  screening-level sediment  hazard scores.  Chapter 4 presents  a summary of the results of
analyses  conducted using this scoring system on  chemical  classes,  industrial categories, and
geographic locations.  Chapter 5 provides a discussion of these analyses and selected applications
of source inventory data.  Appendix A  contains the  data used to  develop hazard scores  for
individual chemicals.   Appendix  B presents the results of the watershed priority listings, and
Appendix C includes  detailed  results of the analysis by industrial category.

1.2.    Anticipated Uses

       EPA's 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:
                                           1-2

-------
       •      Assessment;
       •      Pollution Prevention; and
       •      Enforcement-based remediation.

Given the scope of these broad use categories, the various statutes under which sediment
management actions can occur, and the variety of EPA, other Federal, State, and local program
activities related to  managing risks posed by contaminated sediments, specific uses of the Point
Source Inventory are numerous and varied,  OST has identified four EPA program office uses
of  Point  Source Inventory  data  for screening level  purposes:   (1) sediment monitoring,
(2) effluent guidelines, (3) permitting, and (4) enforcement.  These uses are described briefly
below.  Specific examples that illustrate how Point Source Inventory data meet the particular
needs of the EPA program offices  are provided in Chapter 5.

       The primary goals of sediment monitoring are to determine the extent and severity of
sediment contamination, and to specifically identify potential problem areas, or "hot spots."  Once
these problem areas are  identified, resource managers and  regulatory authorities  can  make
informed decisions, such as posting advisories, gathering additional sediment chemistry and/or
biological effects data, and/or recommending appropriate management actions, such as pollution
prevention. Point Source Inventory data can help identify candidate monitoring locations and
chemicals of concern for ecological and human  health risk assessment studies.  The inventory
data can also be used to identify sites potentially affected by active sources and might require
further assessment prior to dredging.

       An important source control and pollution prevention activity within OST is the effluent
guidelines  program for  point source  pollutant  discharge.    OST  promulgates  national
technology-based effluent  guidelines for the discharge  of toxic chemicals on the basis of
industrial category.  As part of this effort, OST selects which industries and pollutants to regulate.
The Point Source  Inventory will  provide OST with data  concerning which  industries and
pollutants are more  likely  to contribute sediment contaminants.

       One of the largest source control programs within EPA is the National Pollution Discharge
Elimination System  (NPDES), administered by the Office of Wastewater Management. Through
the NPDES program, EPA and State regulatory authorities ensure that discharge from municipal,
Federal, and industrial facilities do not exceed water quality-based pollutant  concentration limits.
States can apply sediment quality  criteria based on  an  existing narrative  standard or  adopt
                                           1-3

-------
quantitative chemical-specific sediment quality criteria as they are developed by OST.  Point
Source Inventory data can be useful in assisting permitting authorities identify facilities with the
greatest potential to contribute to sediment contamination.

       Enforcement of environmental regulations and standards requires specific knowledge of
the activities and  impacts  of potential contributors to environmental contamination.   Once
pollution problems become known, enforcement sometimes plays a significant role in remediating
contaminated areas.  The Point Source Inventory may be useful in providing screening level
information to assist enforcement officials  in  identifying candidate areas,  chemicals, and
industries of concern for developing case studies.

-------
2.0.    DEVELOPMENT OF THE POINT SOURCE INVENTORY

       The methodology employed in developing the Point Source Inventory consists of three
basic steps.  First, a master list of chemicals of interest was compiled. Chemicals were selected
based on their presence in sediment or on EPA lists of chemicals of concern relevant to sediment
contamination and point source releases to surface water.  Second, annual loading amounts were
determined for  the  chemicals of interest.   Two EPA computer data bases  were  used as the
primary sources of release of information. These are the Toxic Release Inventory (TRI) and the
Permit Compliance System (PCS).   Releases  were then assigned to geographical locations,
chemical classes, and  industrial source categories.   The Point Source  Inventory data base,
including records for chemicals not included in the  hazard analysis, is stored in relational data
tables in both SAS  files and dBASE IV.  These relational data tables, which contain chemical
loading,  facility identification  and  classification, and  geographic  location  information,  are
available from OST.

2.1.    Identification of Potential Sediment Contaminants

       Potential  sediment contaminants of interest were identified by  examining  sediment
monitoring data bases, pilot studies of sediment contamination, and EPA chemicals of concern.
The  list of potential sediment contaminants of  interest was compared to a list of point  source
pollutants identified using TRI and PCS; chemicals identified  in both lists  were  selected for
inclusion in the Point Source Inventory. The advantages of using contaminants in TRI and PCS
for this purpose are that sources can be readily identified  and releases can be quantified.
Chemical Abstract Service (CAS) numbers were used to specify nomenclature and to avoid
duplication in compiling the list of chemicals for inclusion in  the Point Source Inventory.

       The three partially overlapping  circles in Figure 1  depict how the universe of chemicals
was  reduced  to identify chemicals of  interest for the Point Source Inventory.   The top circle
represents chemicals that have been reported as being found in sediments.  These  chemicals
include those identified during routine sediment monitoring, as well as those identified in specific
studies and pilot projects.  The bottom  right circle represents chemicals released from identified
point sources. Data for these chemicals are stored in two EPA mainframe computer systems, TRI
and PCS.  The bottom left circle represents chemicals from non-point sources.  Data on these
chemicals are stored in the Aerometric Information  Retrieval  System (AIRS), in TRI (releases
to air), and in data bases of agricultural chemical applications and urban runoff. The intersection

of these three groups define several groups of chemicals, designated by letters in Figure 1,  For
example, the intersection of "point source" chemicals with "monitored" chemicals identifies a
group of chemicals (areas G and E in Figure 1) that have been found in sediment and have point
source release data available.   This report focuses exclusively on these chemicals. Nonpoint
source chemicals (areas "D" and "G") will be considered in a future study.

       For this study, 775 individual chemicals were identified as being monitored in sediment
(Groups A, D, G, and E on Figure 1). The number of chemicals reported in PCS and/or TRI as
being released from point  sources totals 523 (Groups C,  E, F, and G  on Figure 1).  The
intersection of these two sets of chemicals (Groups G and E on Figure  1) yields 324 chemicals
that can be considered potential point source sediment contaminants. This approach may exclude
pollutants that  accumulate in sediment and are  currently being  released,  but have not been
monitored in sediment to date.

2.1.1.  Chemicals Monitored in Sediment

       Several information sources were used to develop the master list of chemicals monitored
in sediment. Each source is briefly described below.

       STORET (STOrage and RETrieval of U.S. Waterways Parametric Data).  STORET is
an EPA-maintained mainframe computer data base that serves as a repository for waterway-
related information,  such as  ambient, effluent,  or biological  water quality  data.  A list of
parameters associated with sediment monitoring was generated using the STORET parameter file.
Upon review, parameters  not related to toxic chemicals (such as bacteriological, biological, and
location) were deleted from the list, as were parameters that did not represent individual chemical
compounds (such as hydrocarbons and halogens).   The resultant parameter file was then used to
retrieve sediment chemical concentration information from the STORET data system.

       ODES (Ocean Data Evaluation System),  ODES is also an EPA-maintained mainframe
computer data base. It stores monitoring information for both marine (primarily) and freshwater
systems.  ODES was developed to support several EPA programs, including the 301(h) sewage
discharge program, the National Pollutant Discharge Elimination System (NPDES) program, and
the Ocean  Dumping program.  It contains approximately 160,000 data records  of sediment
contaminants from over  1,100 stations.  For use  in  this  study, chemical parameters were
                                         2-3

-------
converted to standard CAS numbers and chemical names, and other parameters not relevant to
the current analysis (such as BOD, TSS, etc.) were excluded.


       OPPT Persistent Bioaccumulators Work Group List. This list, supplied by the EPA
Office of Pollution Prevention and Toxics (OPPT), contains  80 chemicals deemed as potential
persistent bioaccumulators based on physical/chemical property and fate data.  Although  not
necessarily monitored, these chemicals were considered to be potential sediment contaminants.


       EPA  Pilot Studies. The two EPA pilot studies described below were considered to be
appropriate data source because they directly address sediment contaminant issues:


       •      The Gulf of Mexico Program Toxics and Pesticides Issues Committee conducted
             an inventory of sediment contaminant sources  to identify the amounts and types
             of chemical discharges (U.S. EPA, 1993m). The study included 49 chemicals of
             concern. The study combined data in TRI and  PCS with data for produced water
             from oil and gas wells and agricultural pesticide usage to determine the amount
             of each pollutant being released.  These values were normalized  using estuary
             volumes and weighted by toxicity of the contaminant to produce the final ranking.
             The Toxics and Pesticides Issues Committee examined: the type and  amount of
             a pollutant being  released; pollutants  found  in sediments; and  fish advisory
             information; to help identify data gaps  and next steps in  terms of management
             activities.

       •      Howard Zar and Matthew H. Williams of EPA Region 5 supplied a draft version
             (May 26, 1993) of a matrix of historical sources of 37 sediment contaminants by
             industry sources.  Primary sources used in the development of the matrix include
             Lyman  et  al.  (1987), Merck  and  Co., Inc.  (1989), Eckenfelder (1980),  and
             Bannerman et al. (1992).

       NOAA's National Coastal Pollutant Discharge Inventory (NCPDI).  This data base is
currently being developed by the  Strategic Assessment Branch of the  Ocean  Assessments
Division, National Ocean Service, National Oceanic and Atmospheric Administration (NOAA).
It will be used by NOAA to assess the effects of pollutant discharges to estuarine,  coastal, or
oceanic water (Basta et al., 1985). Sediment chemicals of concern considered in  this inventory
include heavy metals,  PCBs,  and petroleum hydrocarbons.


       Literature Surveys.  A computer search of the scientific literature concerning sediment
pollutants was conducted using the EPA's On-line Library System (OLS) and Dialog, Lists of
                                         2-4

-------
chemicals were extracted from relevant  reports, especially  Lyman et al.  (1987)  and  PTI
Environmental Services (1991).

2.1.2.  Chemicals Released from Point Sources

       The data requirements of the Point Source Inventory limited the number of useful point
source data  bases.  These requirements include:  (1) classification of the type  of discharger
(industrial category or SIC code); (2) pollutant-specific release data (e.g., measured or estimated
load to 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  meeting these data
requirements.

       Toxics Release Inventory (TRI).  TRI is  a consistent, comprehensive national data base
of toxic chemical  releases to all environmental media.  Congress mandated  its creation to fulfill
the community right-to-know provision (Section  313) of Title III of the Superfund Amendments
and Reauthorization Act of 1986 (SARA).  This  Act  requires the owners/operators of industrial
facilities to report environmental releases of over 300  specified toxic chemicals to the EPA if the
facility meets certain criteria.

       OPPT manages the information on releases submitted by industry.  The Toxics Release
Inventory System  (TRIS) resides on the EPA's IBM ES/9000 located in the National Computing
Center, Research Triangle, North Carolina.  While the TRI data base is updated continuously on
the NCC mainframe, TRI data stored in other media, such as diskettes or CD-ROM, are updated
annually.

       Reports submitted by industry are the sole source of data in TRI. TRI contains release
information from approximately 27,000 facilities. Owners or operators must file reports for their
facility when they meet the following criteria:

       •      Employ the equivalent of  10 or more full-time employees;

       «      Engage in  manufacturing (Standard Industrial  Classification (SIC) Codes 20
             through 39); and

       •      Manufacture, import, or process more than 25,000 pounds of any listed chemical,
             or otherwise used more  than 10,000 pounds of any listed chemical.
                                          2-5

-------
       For each listed chemical (currently over 300 specific chemicals and 20 chemical groups),
the facility must submit a "Toxic Chemical Release Reporting Form" that contains:

       *      Facility identification information such as facility name, parent company, location
             (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 waterbody;

       •      Offsite transfer locations for toxic chemicals, such as POTWs (name and address)
             or waste disposal and treatment facilities (name, address, and EPA I.D. number);
             and

       •      Chemical-specific  information such as chemical  identification (name and CAS
             number); use of the chemical at the facility; quantities released to air (fugitive and
             stack), water (including stormwater), underground 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 Ibs/year (i.e., 0-10,
             11-499, and 500-999) or as a total annual release.  The facility also reports  the
             methods used in determining  the release quantities (e.g., actual monitoring data,
             mass balance calculations, or  emission factors).

       Permit Compliance System (PCS). PCS is the national information management system
for tracking  compliance, enforcement, and permit status for the National Pollutant Discharge
Elimination System (NPDES) program under the Clean Water Act (CWA). The NPDES program
requires permits  for all point source pollutant discharges to navigable United States waterways
(other  than dredged or field material regulated under  Section 404  of  the CWA).  Specific
discharge limits or monitoring requirements  have been set for over 200 individual chemicals.

       PCS resides on  the EPA IBM ES/9000 mainframe  computer.  EPA offices and NPDES
authorized State regulatory agencies may access PCS through the Agency's telecommunications
network.  The general public may obtain information that  is not enforcement sensitive through
Freedom of Information Act (FOIA) requests.

       The EPA Office of Wastewater Management oversees the NPDES program on a national
level.  EPA has authorized 38 States and the Virgin Islands to administer the NPDES program.
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 which are  classified as "major".  Facilities are classified  as
"major" based on consideration of many factors, including effluent design flow, physical and
                                          2-6

-------
chemical characteristics of the wastestream, and location of discharge.  Each permit record in
PCS may contain information that;

       «      Identifies  and describes  the  facility (including a primary  Standard  Industrial
              Classification (SIC) code) to which the permit has been granted;

       »      Specifies the pollutant discharge limits  for that facility;

       *      Records the actual amounts of pollutants measured in the facility's wastewater
              discharges; and

       •      Tracks the facility's history of compliance with construction, pollutant 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 that are in violation of established limits  for the permit.
DMR  data entered  into PCS include the type of violation (if any), concentration and quantity
values, and monitoring period. The PCS data base is  updated twice weekly.

2.2.   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  both data sets,  calendar year 1992
data were used because 1992 is the most recent year for which TRI data are available.  When
combined  into a single data  set, TRI-PCS data comprise the  most comprehensive National
chemical loading data base. However, facilities covered by both TRI and PCS data sets cannot
be readily identified because no common, quality-controlled facility identification data elements
are available in these data bases. Therefore, there is potential for double records of releases for
those chemicals that are reported in both TRI and PCS.

2.2.1.  Toxics Release Inventory Data

       Total release amounts for the chemicals of interest were retrieved for each TRI facility
for each of the 324 chemicals of interest that were reported to be discharged to surface water and
POTWs in  the calendar year 1992.  For each chemical, the total release to surface water and the
adjusted release to POTWs were summed to yield a total facility discharge. Some characteristics
of the  TRI data base may introduce uncertainty into  the  release estimates.   For  example,

                                           2-7

-------
manufacturers required to report to TRI may estimate chemical releases using ranges (i.e., 10 to
499 Ibs/yr).  The ranges are converted to a single value in the TRI data base represented by the
midpoint of the range (i.e., 250 Ibs/yr). Use of these midpoint values may over- or underestimate
the actual releases of TRI chemicals.

       The reported release amounts 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
Data base (U.S. EPA,  199la) indicated that removal rates can be highly variable and dependent
on conditions at the  POTW. Based on peer review comments received on a draft version of this
methodology (Adams, 1994), all pollutants were assigned  a removal rate of 75 percent.  This
removal rate  is  a value that will not tend to significantly overestimate or underestimate actual
loading values.  In  secondary treatment systems, such as  activated  sludge, 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).

2.2.2.  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 (U.S. EPA, 1992a).  EDS uses
the following hierarchy to assign a loading for each pollutant: (I)  reported chemical loading
value in  PCS is used, when available;  and (2)  chemical loading estimated based on discharge
flow and concentration measurement.  Depending on the monitoring requirements imposed by
the permit, concentrations may be reported in many different ways.  Concentration measurements
from PCS were selected in the following order of preference for inclusion in the inventory:

       •      Average concentration;

       •      Maximum  concentration; and

       •      Minimum concentration.
                                          2-8

-------
Loadings were estimated only for records with valid concentrations (as defined by PCS-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 facility.
Data were retrieved at the discharge pipe level for each of the 324 chemicals of concern from
PCS for every NPDES discharger where the requisite data were available.  Concentration data
for each chemical were converted into yearly loads using Equation 1 above. The calculated loads
for a given chemical from each discharge pipe at a facility were summed to yield the facility total
load. In addition, multiple parameters sometimes exist for the same pollutant. For example, zinc
concentrations may  be reported as total zinc and dissolved zinc.  In these cases, the largest
calculated load (usually the "total" load) was selected for inclusion in the Point Source Inventory,

       Concentration measurements for many of the 324 chemicals of concern were recorded in
PCS as below the detection limit. To  handle these records and facilitate various analyses, three
separate data sets were created.   The three PCS data sets differ in their treatment of chemical
concentrations recorded as below the detection limit.  The  first set of PCS loads is based on
setting values below detection equal to zero, the second set is based on setting these values to
half  the detection limit, and the third  set is based on setting these values equal to the detection
limit.  Setting values below  detection equal to the  full detection limit represents the most
environmentally conservative approach, whereas setting them equal to zero represents the least
conservative.  Using half the detection limit is a compromise between the former two extreme
approaches, and is typical for water quality analyses.
                                           2-9

-------
2.3.    Assignment of Geographic Location and Industrial Category

       Once the chemical release amounts were compiled in the Point Source Inventory for TRI
and PCS facilities,  geographic identifiers  were standardized or added to the final data sets.
Federal Information Processing Standards (FIPS) codes, county names, and  State names were
retrieved from PCS  and TRI.  Latitude and longitude coordinates were also retrieved from TRI
and PCS, but  if these values were missing, then the centroid  of the county was used  as the
discharge location.

       Stream reach numbers were assigned to each facility in the Point  Source Inventory to
place chemical discharges into watersheds.  Frequently, the reach number was missing from both
PCS and TRI.  Consequently, reach numbers were added electronically by linking PCS and TRI
facility identification codes to the EPA Industrial Discharge File (IFD). If the reach number was
not available in IFD, then a computerized 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.

       Industrial categories are groupings based on Standard Industrial Classification (SIC) codes
currently used  by both OST and OPPT for purposes such as effluent guidelines development and
assessment of  aquatic impacts of potential releases of Pre-Manufacture Notice chemicals. An
industrial category can be based on a single 4-digit SIC code (e.g., Adhesives and Sealants) or
by a large and variable range of SIC codes (e.g., Metal  Finishers).

       Each facility in the Point Source Inventory 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 may correspond to different SIC codes,  industrial category
groupings are  only approximate.  There were 46 industrial categories overall.  PCS data were
grouped into 44 industrial categories, and TRI data were grouped into 41 industrial categories,
TRI includes the ink and waste oil reclamation industrial categories, but PCS does not. POTWs,
coal mining, hospitals, oil and gas, and warehousing and storage are not included in TRI, but are
included in PCS.

2,4,   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, however,
preclude the  use of the NSCI as a targeting tool to prioritize geographic areas, chemicals, and
industries for further evaluation.  In some instances, the limitations  may  affect small scale
analyses (i.e. individual stream or lake waterbody segments); 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 information.

       The NSCSI database and analyses are primarily limited by the quality and quantity of
existing  data in national  EPA data bases.  The broad  scope of the inventory has prohibited
collection of large amounts of data from numerous  site-specific information sources at this time.
Therefore, the inventory relies on data available in national electronic data bases such as TRI and
PCS.   While a considerable  volume of information is  contained in these  data bases,  many
important parameters are not available.  In  particular, no national electronic data base accurately,
consistently, or completely stores information concerning the characteristics of waterbodies, such
as underlying sediment type.  Furthermore, data quality  assurance/quality control are  important
issues when  using  data from large national data  bases that receive input  from a variety  of
sources;  the  amount of data  contained in these national data  bases is too large to conduct
comprehensive verification  procedures.  In addition, it  should  be  noted that  the number  of
facilities discharging chemicals of concern 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 stormwater permits in  PCS) or economic  conditions.  Given  these
qualifications, the three major limitations of the inventory as it is now structured are:

       •       The inability to predict the exact  location of sediment contamination that may
              result from point source releases (i.e., the geographic analyses are  limited  to
              identifying  areas or  watersheds where point source releases occur);

       •       The inability  to indicate definitively whether a point source release will cause a
              sediment contamination problem; and

       *       The inability to assess sediment contamination arising from nonpoint source inputs
              (including deliberate introduction of toxic substances, such  as  pesticides and
              household chemicals,  to  the environment) and  from point  source inputs not
              represented in the PCS or TRI data bases (e.g., facilities which  do not meet a TRI
                                          2-11

-------
             reporting criterion and for which no NPDES permit limits have been established
             but from which chemicals of concern are being discharged).

       Conclusions based on the Point Source Inventory should  take into consideration the
inherent limitations of the data bases and the assumptions used in creating the inventory. Factors
associated with data base limitations that  should be  considered include:   the  possibility of
erroneous data in TRI and PCS; the limited coverage of TRI and PCS; and inherent data base
biases.  Neither PCS nor TRI accurately reflect the full extent of toxic chemical releases from
point sources, and the data contained  in them may be inherently biased.  Although several
hundred individual chemicals are represented in each data base, as many as five to ten times
more chemicals  may 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  is partly a function of the policies and practices of the State or Regional permitting
authority and of the industrial activities  conducted at the facility, this may lead to biases toward
some geographic regions and industrial categories.  Furthermore, only approximately 10 percent
of permitted dischargers are classified as  "major"  and have extensive records from  which
chemical loads can be derived (See Section 2.2.2). Facilities subject to TRI reporting represent
a relatively narrow range of commercial activities (manufacturing only). Although the TRI data
base 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 may overcome some of these limitations and the
biases they create.

       Other potential sources  of error are  associated  with the assumptions  used in the
assignment of geographic location and industrial category.  In many cases, geographic location
assignment was made  using latitude and longitude coordinates of the facility and the nearest
stream reach. However, the nearest stream may not be the receiving stream for some facilities.
Also, for TRI data, POTW receiving streams could not be identified; PCS contains more reliable
information on location and discharge data on POTWs. Consequently, 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 waste generated from non-primary SIC code activities are included with these  from the
primary SIC code in the Point Source Inventory.

3.0   DEVELOPMENT OF SEDIMENT HAZARD SCORES

      One major objective of this project was to develop and employ a screening- level hazard
analysis procedure that can be used to generate a relative ranking of chemicals and industrial
source categories that are potential contributors to sediment contamination and to prioritize
watersheds for  collection of  additional information  that will  lead to  the identification of
additional monitoring needs.   To enable screening-level analyses, chemical-specific sediment
hazard scores (SHSs) 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 SHSs  to produce HAZard-weighted RELease  scores
(HAZRELs):
                               HAZREL = SHS * ACL                   Equation (2)
   where:
      SHS   = Sediment Hazard Score;  product  of the FATE and TOX
               scores as described below; and
      ACL  = Annual Chemical Load; annual release amount (kg/year) of
               a specific chemical  from  individual industrial or municipal
               treatment facilities.
       SHSs are intended  to represent both the potential of a particular chemical  to cause
sediment contamination upon release into the water column (independent of the characteristics
of the site) and the potential ecological and human health risk posed by the chemical. The SHS
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 represent the
potential for a chemical to partition to and persist in sediment.  Three previous works were
examined, in particular, to assist in the development of the screening-level hazard analysis
methodology:
                                         3-1

-------
       •     Established methods of determining sediment toxicity (U.S. EPA, 1992b);

       •     Superfund's Hazard Ranking System, Final Rule (Federal Register,  1990); and

       •     NOAA's pesticide hazard rating system (Pait et al,, 1992).

       Calculated SHSs, TOX scores, and FATE scores,  along with the information required
to calculate  them (i.e.,  aquatic and human toxicity data, physical/chemical properties, and
estimated sediment chemistry screening values),  are presented in Appendix A of this report.

       The HAZREL score is a unitless index  of potential  sediment contamination based on
chemical/facility-specific releases, physical and chemical properties, and potential environmental
risk.   HAZREL scores indicate the relative  potential for sediment contamination from
documented  point source inputs in the absence of any knowledge  of historical or non-point
source inputs and  site-specific conditions (e.g., stream velocity, organic carbon content of
underlying sediment) affecting chemical fate and inter-media partitioning.  HAZREL scores may
be used to rank and compare potential sediment contamination sources.  Once the HAZREL
scores were  calculated for each chemical-facility combination, a number of data aggregations
were performed to evaluate chemical classes and industrial categories for their potential risk of
causing sediment contamination, and to identify geographic areas where the risk of contamination
from active point sources may be the greatest. The following equations are examples of these
aggregations. For a geographic analysis of inventory data, equation (3) depicts HAZREL scores
combined at the USGS Regional Hydrologic Unit (USGSRGN) level:
                        HAZRELUSGSRON - Ł HAZREL(USGSKGNJ)           Equation (3)

       where:  n is the total number of HAZREL scores within USGSRGN.
For the analysis of individual chemicals by  industry, equation (4) depicts HAZREL scores
combined for specific chemicals (CHEM) from specific industrial categories (ICAT):
                                         3-2

3.1.   Chemical-Specific Toxlcitv Score

       Sediment contamination is a function of the mixture and concentration of toxic pollutants
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.
Analysts and managers can use numerical effects-based, chemical-specific concentration  values
to assist in the evaluation of sediment chemistry data and  to identify and prioritize problem
areas.  For purposes of this analysis only, EPA derived estimated sediment chemistry screening
values using a variety of readily  available assessment methods.  The TOX score component of
the SHS was calculated by taking the inverse of the chemical-specific screening value reported
in units of mg/kg. Because the inverse of the sediment chemistry screening value is used, the
TOX score increases in direct proportion to the potential adverse effect of the chemical.

       Several methods are currently available for  developing  sediment chemistry screening
values (U.S. EPA,  1992b).   Most of  these methods require information  on  site-specific
conditions (field data) and chemical-specific properties.  However, because field data are not
available for each point source discharge location, screening values for use in analyzing the Point
Source Inventory releases data 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 Effects Range approach and the
State of Washington Apparent  Effect  Threshold  approach each  utilize existing sediment
chemistry and biological effects data from a variety  of sites,  and the 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.
                                          3-3

-------
       In this study, the Equilibrium Partitioning approach was used to develop estimated
sediment  chemistry  screening  values  for  nonionic organic compounds; the Effects Range
approach was used for deriving estimated sediment chemistry screening values for metals, and
the Apparent Effects Threshold approach was used for deriving estimated sediment chemistry
screening values criteria  for ionic organic compounds.  These  approaches,  along with the
justifications for their use, are described on the following pages. Appendix A contains a listing
of all the estimated sediment chemistry screening values, as  well as the supporting aquatic life
and human  health toxicity data, for the chemicals of concern  contained  in the Point Source
Inventory.

       It is  important to note that the certainty to 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 were
intended and appropriate  for use  in this report 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 over-  or  under-protective  of  actual site-specific  sediment  because
       methodological and exposure conditions vary considerably.

•     Values are general approximations of concentrations potentially leading to adverse effects
       because data and assessment methods are currently being compiled and developed.

•     Values are based on a composite of several different sediment assessment approaches and
       a variety of data sources, the application of which EPA has not adopted or endorsed for
       use outside this analysis.

Sediment quality criteria and estimated sediment chemistry screening values are not equivalent.
EPA  has proposed sediment quality criteria for five chemicals based on extensive data quality
and quantity requirements and methodologies that have gone through extensive peer review for
the intended application.   The estimated sediment chemistry screening values  for additional
chemicals presented in Table A2 of Appendix A of this  report are not sediment quality criteria
and should  not be used as such.

-------
       Nonionic Organic Compounds:  Equilibrium Partitioning (EqP)

       The EPA Science Advisory Board (SAB) gave a favorable review to the equilibrium
partitioning (EqP)  approach for development of sediment quality criteria for nonionic organic
chemical pollutants that  are protective of aquatic life and human health  (from ingestion of
organisms) (U.S. EPA, 1992c).  EPA's Office of Water has proposed marine and freshwater
sediment  quality  criteria  using the  EqP  approach  for five  nonionic  organic  chemicals:
acenaphthene, dieldrin, endrin, fluoranthene, and phenanthrene (U.S. EPA 1993c-g). Calculated
aquatic life-based  freshwater criteria, normalized to 1 percent organic carbon, were used as
estimated sediment  chemistry screening  values for these five compounds in  the  study.
Freshwater criteria were  used  because the majority of locations addressed in  the inventory are
freshwater waterbodies.

       EqP is based on predicting interactions among sediment, interstitial or pore water (i.e.,
the water between sediment  particles),  and  chemical  contaminants.   EqP  was developed
following observations that adverse biological  effects  were poorly correlated with dry weight
chemical concentration in bulk sediment, but well correlated with pore water concentration as
well as organic carbon normalized concentration (Di Toro et al.,  1991).   EqP is  a simple
screening model for 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^,) and the site-specific organic carbon content. EPA recommends using chronic
water quality criteria as the threshold pore water concentration in  developing sediment quality
criteria.  The EqP  model makes the following assumptions:

       »      Solid and water phases are in equilibrium.

       »      Organic carbon  is the primary agent of chemical adsorption.

       •      The threshold concentration protective  to  aquatic life in the  water column is
              representative of the threshold concentration protective to benthic organisms (i.e.,
              chemical sensitivity is similar).

       For the nonionic organic chemicals addressed in the Point Source Inventory for which
EPA has  not  established  sediment quality criteria,  EqP-based estimated sediment chemistry
screening  values were calculated  separately for the  protection  of aquatic  life and for the
protection of human health using the following equation (U.S. EPA,  1993b; Di Toro et al.,
1991):

                                          3-5

-------
                             SCV = TWC  *  KM  * % OC                (Equation 5)

   where:
       SCV  =  Estimated sediment chemistry screening value (mg/kg);
       TWC  =  Threshold water concentration, EPA criterion or other representative
                value protective of aquatic life or of human  health (mg/L);
       KO,.    =  Organic carbon-water partitioning coefficient (L/kg); and
       %OC  =  Percent organic carbon in sediment,  assumed to be 1%.
       Except for the five chemicals with aquatic life-based EPA sediment quality criteria, the
more stringent of the calculated aquatic life-based or human health-based screening value was
used to represent each chemical for the toxicity component of the hazard score. EPA considers
this selection to be appropriate because the Agency is committed to protecting both human health
and ecology. Some chemicals exhibit a stronger adverse effect on aquatic life than on human
health, whereas other chemicals exhibit the reverse.  Selection of the more stringent scrrening
value ensures that the more serious overall threat is addressed.

       The  threshold water concentration (TWC) for aquatic  life protection was set at the
freshwater final chronic value when national water quality criteria were available.   Criteria
values  were derived from toxicity studies using a diverse genera of aquatic life and have been
published previously by EPA.  Chronic criteria are defined as the 4-day average concentrations
of toxicants  at which diverse genera of aquatic organisms should not be unacceptably affected,
provided that these levels are not exceeded more than once every 3 years.

       The  EqP approach is generally recommended  to be used  in conjunction with a site-
specific organic carbon (OC) fraction and water quality criteria (U.S. EPA, 1993b; Di Toro et
al., 1991).  However, for this study, the organic carbon content of sediment at each site is not
available, and water quality criteria do not exist for a large number of the chemicals of interest.
Many studies have shown that the OC fraction in marine systems may vary from 0.2 percent to
30 percent, depending largely on the sand, silt, and clay content of the sediment (Di Toro et al.,
1991).  Freshwater systems typically vary from  1 percent to 5 percent  OC.  OC concentration
of 1 percent was assumed to be representative of both marine and freshwater environments for
the purpose  of guideline calculation for the hazard analysis in this study.

       U.S. EPA (1993b) recommends using the following regression equation to calculate the
organic carbon-water partition coefficient (K^) from the octanol-water partition coefficient (K^,,):

                                          3-6

-------
                                  = 0.00028  +  0.983 * log10ATw           (Equation 6)
Octanol-water partition coefficients derived from the slow  stir  flask method were  selected
preferentially over other laboratory values reported in literature (U.S. EPA, 1993b).

       For chemicals without a national chronic water quality criterion, a value selected from
compiled chronic toxicity test data for individual aquatic species (or acute toxicity test value
multiplied by an acute:chronic ratio) was assumed to be representative of general aquatic life
toxicity.  This assumption, which allows extrapolation from  acute data to chronic protection,
may be over- or under-protective for some chemicals under consideration.

        The following hierarchy was used to select a representative value, in descending order
of priority:

       •     Lowest  reported maximum  allowable  toxic  concentration (MATC),  lowest
             observable effect concentration  (LOEC), or no observable effect concentration
             (NOEC);

       •     Lowest reported chronic growth or reproductive toxicity test concentration; and

       »     Estimated chronic toxicity effect level from a measured acute:chronic  ratio for a
             less sensitive species, quantitative structure activity relationship (QSAR) model,
             or default acute:chronic ratio of 10:1.
       Chronic aquatic test data were used to identify the three effect levels  of potential
significance: the no  observed effect  concentrations  (NOEC), the  lowest  observed  effect
concentration (LOEC), and the maximum allowable  toxic concentration (MATC).  Chronic
aquatic tests measure  the effects of long-term exposure to a chemical.  Test  endpoints include
such variables  as survival percentage, hatchability,  and normal  larvae weight  and length.
Chronic tests of longer exposure duration measure endpoints such as growth  and reproduction.
NOEC is the highest toxicant concentration to which test organisms have been exposed that
resulted in no observable adverse effect.  LOEC is lowest toxicant  concentration at which a
chronic effect on  a test organism has been observed. The MATC is the geometric mean of the
NOEC and  LOEC and is meant to represent the threshold level where chronic effects would
begin to occur.  For the estimated sediment chemistry screening value derivation, MATC values
                                          3-7

-------
were selected first, followed by LOEC values, and lastly NOEC values as a reflection of the
decreasing level of confidence in the accuracy of these values to represent the actual threshold
chronic effect level.

       For chemicals that do not have chronic aquatic life criteria, MATCs, LOECs, or NOECs,
chronic effect levels were obtained from readily available sources of chronic toxicity test data.
The preferred information source was the EPA's Assessment Tools for the Evaluation  of Risk
(ASTER)  system,  which combines the  AQUatic  toxicity  Information Retrieval data base
(AQUIRE), the EPA Environmental Research Laboratory-Duluth (ERL-Duluth) fathead minnow
data base, and tables of toxicity test results from water quality criteria documents.  The ASTER
system differentiates between test data in AQUIRE that are likely to be of good quality and test
data in AQUIRE that are of unknown quality, according to the following criteria:

       *     Test pH within range of 6.5 - 8.5;

       •     Review  code  1  (methodology  section  cites published or  well-documented
             procedures;  satisfactory  control; measured  concentration; temperature, pH,
             dissolved oxygen; and hardness are  reported) or code 2 (one or more of the
             following may occur: control mortality not reported; no solvent control when a
             solvent is used in the test; unmeasured concentration; water chemistry variables
             not reported or incomplete);

       •     No formulations or carriers used;

       •     Measured values and flow-through exposure only for tests on fish (no static
             exposure); and

       »     Measured values only for invertebrates  or plants (exposure may be static or
             flow-though).

Test results from ERL-Duluth fathead minnow data base were assumed to be of good  quality.
However, test results reported in water quality criteria documents are of unknown quality. The
lowest reported concentration from a chronic growth or reproductive test on a North American
native fish or invertebrate, or biologically significant (i.e., chlorophyll production) EC5Qtest for
an algal species, was selected preferentially from the pool  of test data likely to be of good
quality, or alternatively from the pool of data of unknown quality.  If appropriate test data were
not available from ASTER, other primary or secondary information sources were consulted.
                                          3-8

-------
       Chronic toxicity effect levels were estimated when measured values were not available.
The preferred method for estimating a chronic toxicity effect level was to use an aeutexhronic
ratio (ACR), ACRs are based on measured acute and chronic effect levels for the same species.
The calculated ACR ratio is applied to the acute aquatic toxicity criterion or acute toxic effect
level selected for the pollutant of concern.  This method was also used in instances where the
measured chronic toxicity effect level  in one species was greater than  the acute criterion or
representative acute toxic effect level in another more sensitive species.  The acute toxic effect
level used was typically the  lowest reported  acute test concentration  (24- to 96-hour median
lethal concentration (LC50s)) for a North American resident species of fish or invertebrates. As
with chronic toxic effect levels, a test result of good quality as defined by ASTER was selected
ahead of a test result of unknown quality.

       The  next  preferred method was to use ERL-Duluth's quantitative structure activity
relationship  (QSAR) model.  QSAR derives statistically-based relationships between physical-
chemical properties and biological activity. The QSAR model uses measured toxicity test results
for compounds with similar chemical structures and properties to estimate MATC  values for
compounds whose chemicals  structure and properties are known or may  be estimated.

       The least preferred method for estimating a chronic toxicity effect level was to apply an
assumed ACR of 10:1  to a known acute toxic effect level.   The ACR of 10:1 is based on
OPPT's  "rule of thumb" for estimating chronic toxicity  when  no data are  available.   This
assumes  that the chronic toxicity value is 10 times lower than the acute value.   There is
uncertainty associated with aquatic life-based criteria and other selected aquatic life toxic effect
levels.  The degree of uncertainty varies for each chemical and is not assessed as part of this
study.

       The equilibrium partitioning model can also be used to calculate estimated sediment
chemistry screening values for the protection of human health  from ingesting contaminated
organisms (NY DEC, 1993).  EqP human health-based estimated sediment chemistry screening
values were calculated using Equation 5 and substituting the human health value (HHVAL),
calculated using  Equations 7 and  8,  for the threshold water concentration (TWC).   This
application assumes that the same factors that control availability for aquatic toxicity  control the
availability  for biological uptake,   A  chemical-specific  bioconcentration factor  is  used  to
determine the partitioning of chemical from pore water to biota.   This application ignores
biological uptake from dietary sources, such  as direct ingestion  of  sediment  and ingestion  of
                                          3-9

-------
lower trophic level organisms (i.e. bioaccumulation). U.S. EPA (1991b) gives two equations
for determining a water column level protective of human health from ingesting organisms; one
for chemicals exhibiting carcinogenicity and one for chemicals exhibiting other systemic health
effects:
       Systemic Toxidty

       SF          = Cancer potency slope factor (mg/kg-day)"1 (chemical -specific);
       Risk level    = Excess cancer cases (10"*);
       RfD        = Reference dose (mg/kg-day) (chemical-specific);
       BCF        = Bioconcentration factor (L/kg) (chemical-specific);
       Ifuh          = Daily ingestion rate of fish (0.0065 kg/day); and
       BW         = Body weight (70 kg).
       EPA employs the above equations with the identified default values to calculate human
health-based water quality criteria for consumption of aquatic organisms (U.S. EPA, 1991b).
Reference doses (RfDs) are chemical potency factors for systemic toxicants, and are usually
derived from animal toxicity test data to which safety factors are applied.  Slope factors (SFs)
are determined  from  available human epidemiology data and animal toxicity studies to which
safety factors are applied. For carcinogenic compounds,  10"6 (one in a million excess cancer
cases above background allowed) is used as the acceptable human  health risk level, consistent
with Office of Water policy in calculating human health water quality criteria.  The primary
source of RfDs and SFs used to develop the HHVALs was EPA's  Integrated Risk Information
System (IRIS).  A secondary source was the OSWER/ORD Health Effects Assessment Summary
Tables (HEAST).  Bioconcentration factors (BCFs) are extracted  primarily from EPA water
quality criteria documents.  For general population exposure, U.S. EPA (1991b) recommends
using 6.5 grams as a daily fish consumption rate and 70 kg as an average adult body weight.

-------
       The human health application of EqP has greater associated uncertainty than the aquatic
life application because of the many additional  input parameters, such as BCF, RfD,  and SF.
However, human health-based estimated  sediment chemistry screening values are important
because many chemicals discharged by point sources and found in sediment can potentially pose
a greater potential threat to human health than to aquatic life.  Although human exposure to
contaminated sediment  may also occur via direct dermal  contact or from drinking  water
contaminated by solubilized or resuspended sediment pollutants, exposure via these routes is
expected to be minimal compared to exposure via ingestion of contaminated organisms.

       Metals:  Effects Range-Median (ER-M)

       EPA is currently in the process of  developing a methodology for deriving sediment
quality criteria for metal contaminants (U.S. EPA,  1992b).  In  the interim, alternative means
of establishing estimated sediment chemistry screening values, based on the National  Oceanic
and Atmospheric Administration  (NOAA) National Status and Trends Program (NSTP) effects
range approach, are employed for this study. Environment Canada, the Florida Department of
Environmental Regulation, the California Water Resources Control Board,  and the New York
State Department of Environmental Conservation all utilize an effects range approach in their
sediment quality management programs (U.S. EPA,  1992b;  NY DEC, 1993).  The following
discussion is adapted  largely  from the description  of the derivation of New York sediment
quality criteria for metals in NY  DEC (1993).

       The complex interactions between metal  contaminants  and the aquatic environment
preclude use of simple screening-level approaches to estimated  sediment chemistry screening
value derivation, such as the EqP approach  for nonionic organic compounds  described above.
The potential toxicity of metals in the aquatic environment depends largely on the form in which
the metal is present (Manahan, 1991). Metals can be found in a dissolved ionic form, dissolved
neutral form, in inorganic precipitates (i.e., hydroxides and carbonates), or complexed to organic
or mineralogic (i.e., clay  particles) material.   The form of metal  present,  in turn, is highly
dependant on site characteristics such as pH,  oxidation-reduction  (REDOX) potential,  and
available complexing ions and ligands. In general, the dissolved fraction of metals account for
most bioavailability  and toxicity to aquatic organisms (U.S. EPA, 1993a).

       The effects range approach for deriving  estimated sediment chemistry screening values
involves matching dry-weight sediment contaminant concentrations with associated biological
                                         3-11

-------
effects data.   Data from modeling,  laboratory, and  field studies are used to determine the
concentration ranges that are rarely, sometimes, and usually associated with toxicity (U.S. EPA,
1992b).   This  approach  is valid  for  extrapolation  from  contaminant  concentrations  to
observations of effects.  For the NSTP, Long and Morgan (1990) assembled sediment data for
10 metals and several organic compounds from freshwater and marine environments nationwide.
For each chemical, sediment concentration data with incidence of observed adverse biological
effects were isolated and ordered. The authors identified the lower 10th percentile concentration
as the effects range-low (ER-L) and the 50th percentile concentration as the effects-range median
(ER-M). Sediment contaminant concentrations below the ER-L are said to be in the "no effect
range", values between the ER-L and ER-M are in the "possible effect range", and values above
the ER-M are in the "probable effect range".

       The Ontario Ministry of the Environment used a similar effects based approach to derive
lowest effect  levels (LEL) and severe effect levels (SEL) (NY DEC, 1993).  New York State
has adopted the  lower  of the Long and Morgan ER-L or Ontario LEL, and  the lower of the
Long and Morgan ER-M or Ontario SEL, as sediment screening criteria for 12 metals.  The
Ontario levels are generally lower than the Long  and Morgan values.  This may be because
much of the data used to generate the Ontario effects range values were from Lake Ontario, a
relatively pure waterbody where fewer ligands would be available  to bind metals, and lower
metal concentrations could cause toxicity.  In contrast, Long and Morgan included samples from
more eutrophic waterbodies.  New York justified the use of the  lower of the Ontario or Long
and  Morgan  effects range  values on the basis that  much of  the freshwater  in New York is
oligotrophic and similar to  Lake Ontario (NY DEC,  1993).

       The NSTP effects range approach does not account for factors such as organic matter
content, acid  volatile  sulfide concentration, and  particle size distribution  that can mitigate
bioavailability and, therefore, toxicity of metals in sediment.  Furthermore, the NSTP effects
range approach may not separate toxicity associated  with metals from  toxicity associated with
other compounds.  This empirical, weight  of evidence type  of approach, as opposed to the
mechanistic equilibrium partitioning  approach, has drawn some criticism because it does not
account for bioavailability.  In particular, a great deal of attention in recent literature has focused
on the  role of acid volatile  sulfide (AVS)  in  limiting metal bioavailability and toxicity in
sediment (Di Toro et al., 1990; Allen et al., 1993).
                                          3-12

-------
       A large reservoir of sulfide exists as FeS in anoxic sediment.  Sulfide will react with
several divalent transition metal cations (cadmium, copper,  mercury, nickel, lead, and zinc) to
form  highly insoluble precipitates and thus control the bioavailability of these metals in pore
water (Allen et al., 1993). It follows in theory, and with verification (Di Toro et al., 1990), that
divalent transition metals will not begin to cause toxicity until the reservoir of sulfide is used up
(i.e.,  the molar concentration of metal in sediment exceeds the molar concentration of sulfide
in sediment), typically at relatively high dry weight metal concentrations.  This observation has
led to a laboratory measurement technique of calculating the ratio of simultaneously extracted
metals to acid volatile  sulfide concentrations (SEM/AVS) from field samples  to determine
potential toxicity.

       For the following  reasons, ER-M values from Long and Morgan (1990)  were used to
derive chemical-specific toxicity scores for  metals included in the  hazard  analysis of source
inventory data. First, discharge data from PCS and TRI did not include measurements of AVS
or SEM, therefore, the use of EPA's proposed approach for metals was not possible.  Second,
for several reasons effects range values  from other  studies, such as Long et al. (1993) and
Ontario effect levels, are not as appropriate as values from  Long and Morgan (1990).   Values
from  Long et al.  (1993)  are based on  marine samples only,  whereas the majority of point
sources addressed in this inventory discharge into  freshwater.  Ontario effect levels are based
on  samples from  oligotrophic  waters,   whereas waters receiving  municipal and  industrial
wastewater tend to be eutrophic.  Third, because of the uncertainty in isolating effects solely
from  individual metal species,  and in light of recent evidence on  the effects of AVS, ER-L
values may be overly conservative.  Consequently, ER-M values were used to predict ecological
effects for  metals  in sediments.  It should be noted that the strength of predictability varies
considerably among metals (Long et al.,  1993) as it does for organics.

       loniwble Organic Compounds: Apparent Effects Threshold (AET)

       At present,  no effects range values or equilibrium partitioning approach are available for
ionizable or polar organic compounds. lonizable organic compounds can exhibit a net electrical
charge that increases their solubility and decreases their potential to accumulate in sediment.
The effect of charge on solubility increases the number of factors that control the pore water to
sediment equilibrium and preclude use of the EqP approach described above.  However, Barrick
et al.  (1988)  report  apparent effect threshold (AET)  values  for  seven  ionizable  organic
compounds based on samples from Puget Sound in Washington  State.  The AET approach is an
                                          3-13

-------
empirical data approach similar to the effects range approach. In the AET approach, dry weight
chemical concentrations and associated adverse biological effects data are used to determine the
dry weight concentration at  which specific adverse effects would always be expected  at a
statistically significant (P=0,05) level (U.S. EPA, 1992b).  Several local and regional programs
in Washington State currently  use  the AET  approach  as the basis for level of concern
concentrations in Puget Sound (U.S. EPA, 1992b).  For this study,  the  lowest AET values
reported for an adverse effect from Barrick et al. (1988) were selected as estimated sediment
chemistry screening values for the seven ionizable organic compounds.

3.2.   Chemical-Specific Fate Score

       The second component of the Sediment Hazard Score (SHS) is the FATE score.  The
FATE score  is the product  of the air/water  partitioning sub-factor  (HLC score), sediment
adsorption sub-factor (KOC  score), and  biodegradation  sub-factor (BIODEG  score).   The
potential for a chemical to accumulate in the underlying sediment after being released  into the
water column depends greatly on site-specific characteristics such as sediment organic matter
content, temperature, suspended paniculate matter, and the lotic or lentic nature of the receiving
waterbody.  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 sub-factors was  used.  Three physical-chemical  properties for organic sediment
contaminants were obtained  for the chemicals in the inventory:   the  sediment adsorption
coefficient or K^., Henry's Law Constant (HLC), and the aerobic aqueous biodegradation  half-
life.

       The two  transport sub-factors,  air-water  partitioning and  sediment adsorption, are
represented by chemical-specific HLC and K^, values, respectively.  These sub-factors  were
treated in a manner similar to that used in the pesticide hazard rating system devised by Pait et
al. (1992) (i.e., individual HLC and K^ values were  assigned scores  ranging from 0. i to 1).
These values were then multiplied to produce a score that represents the likelihood of transport
to the sediment.
                                          3-14

-------
       The  aqueous  degradation sub-factor is represented by chemical-specific  aerobic
biodegradation  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 sub-factors value to arrive at the final FATE score.

       Air-Water Partitioning Sub-factor

       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-m3/mole) 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:
    1. All values > 10~3 were assigned a score of 0.1.

    2. All values < 3 x 10"7 were assigned a score of 1.0.

    3. All other values were assigned  a score using Equation 9 to evenly distribute
       scores across the range of values:

correlated with solubility and fairly well correlated with BCF.   KOC scores were calculated
according to the following steps:
       1.  All values > 106 are assigned a score of 1.0.

       2.  All values < 102 are assigned a score of 0.1.

       3.  All  other values are assigned a  score  using  Equation 10  to  evenly
           distribute scores across the range of values:
                       KOC
                           score

       KOCKore      =     Sediment adsorption sub-factor; and
                     =     Organic carbon-water partition coefficient (L/kg).
       Aqueous Biodegmdation Sub-factor

       Although  many physical and chemicals processes can contribute to degradation  (e.g.,
hydrolysis, photolysis, biological degradation), aerobic biodegradation half-life was selected 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 over-  rather
than under- estimate a chemical's persistence potential.  Aerobic aqueous biodegradation half-
lives are empirically-derived time periods when half of a chemical load released to water is
degraded by microbial action in the presence of oxygen.  Although the degradation products may
be  equally or even more toxic than the parent, evaluation of chemical  metabolites was not
considered in the hazard analysis.  Aerobic 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:
                                        •   3-16

                                            f2
    where:
       X     = Loss rate constant (year)"1;
       ln(2)  = Natural log of 2;
       tw     = Aqueous aerobic biodegradation half-life (days); and
       365   — Conversion factor (days per year).
Because other factors, such as deep burial, may become important over time, chemicals with
reported half-lives greater than seven years were assigned a half-life of seven 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:
                                  BIODEGxort  = -                      Equation (12)
       The FATE Score was calculated by combining the HLC, KOC, and BIODEG scores
according the following formula:
           = (BIODEGK
-------
Therefore, metals were assigned a KOC score of 0.5, representing the midpoint of all possible
values.
3.3.   Sample Calculations jn^ Sensitivity Analysis

      The overall general equation for the SHS is:
                         SHS = TOXSCORE * FATESCORE            (Equation 14)

    where:
      TOXSCORE  = SCV-1
      FATESCORE = KOCwore * HLCKOre * BIODEG^
      SHS          = Sediment hazard score (unitless);
      SCV          = Estimated sediment chemistry screening value (unitless;
                       based on values in units of mg/kg);
      KOC^ore      = Sediment adsorption sub-factor (unitless);
      HLCKore      = Air-water partitioning sub-factor (unitless); and
                    = Aqueous biodegradation sub-factor (unitless).
      The function of the estimated sediment chemistry screening value in the denominator of
the SHS  is to  increase or decrease the HAZREL score 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 an estimated sediment chemistry screening value less than 1 mg/kg
has a SHS greater than  1, and higher HAZREL scores  than ACLs.  On  the other hand, a
chemical with an estimated sediment chemistry screening value greater than 1 mg/kg has a SHS
less than  1, and lower HAZREL scores than ACLs. The magnitude of the effect on HAZREL
is in direct proportion to the magnitude of the estimated 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 significance.

      The function of the BIODEG score  is to adjust the HAZREL score relative to the ACL
based on a chemical's persistence in  the aquatic environment. Half-life values in days were
converted to a loss rate constant in (years)"1  to be consistent with the ACL units of kg/year. 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

                                        3-18

-------
greater than 1 that increases the HAZREL score.  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  that decreases the HAZREL score.   This
indicates that the steady-state mass is less than the annual load (i.e., net loss).  The magnitude
of the effect on HAZREL 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 HAZREL depending
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, then the HAZREL score
will decrease by as much as one order of magnitude.  Likewise, if a chemical has a strong
tendency to volatilize, then the HAZREL score will also decrease by as much as one order of
magnitude. This  relatively smaller adjustment was  made because of the many mitigating site-
specific factors that affect inter-media partitioning.

      The estimated sediment chemistry screening values (SCVs) and ACLs for the chemicals
of concern in  this analysis vary  over more orders of magnitude than do biodegradation half-lives,
KOC scores,  and  HLC scores.  Therefore, HAZREL scores are primarily driven by ACL and
chemical toxicity.

      The specific calculation of the estimated sediment chemistry screening value and FATE
score sub-factors  depends on the type  of chemical (i.e.,  metal,  non-ionic organic, ionizable
organic), the  magnitude of  the HLC and K^., and whether the threshold  water concentration is
based on protection of human health or aquatic life if the estimated sediment chemistry screening
value is calculated using the equilibrium partitioning approach.  Sample SHS calculations are
provided in Figures  2, 3,  4,  and 5 to show  the specific calculations for  the various SCV
estimation methods used  for toxic effect types:   acenaphthene  (aquatic  life  protection; EqP),
cadmium (aquatic life protection; ER-M), 1,2,3,4-tetrachlorobenzene (human health protection
against  systemic  effects;  EqP),  and tetrachloromethane  (human  health  protection against
carcinogenic effects;  EqP).

      The sensitivity of the parameters used in SHS calculation, with the exception of K^ are
depicted in Figure 6.  Note, the x-axis labels represent the factor  by which the original values
are multiplied (i.e., the effect of doubling a given parameter on  the SHS  is read from the point

resulting from altering input parameters.  For example, if the  percent OC  is halved ("0.5" on
the x-axis),  the SHS would be doubled ("2" on the y-axis).  The sensitivity of K^. is depicted
in Figure 7 in three parts: one for the effect based on KOC score (increase in K^. means greater
propensity to partition to sediment and higher SHS), one for the effect based on the equilibrium
partitioning  approach (increase in K^. means less mass in the bioavailable dissolved fraction or
interstitial water and lower SHS), and one for the overall K^ effect.  As K^.  increases, there
is a lower relative concentration expected in pore water.

       Most of the  parameters  used  in  SHS calculation have a fair amount of uncertainty
associated with  their values.  For  example, human health  reference doses have uncertainty
spanning perhaps an order of magnitude or greater (U.S. EPA, 1993J).  When multiplied, the
overall  uncertainty in the SHS precludes their use in  analyses that require a high degree of
accuracy.   However,  this level of uncertainty  is acceptable for  meeting the  objective of
performing a screening level hazard analysis.

4.0.   RESULTS OF SCREENING-LEVEL HAZARD ANALYSES

       The screening-level hazard analysis of Point Source Inventory data for 1992 may be used
as a tool for evaluating general patterns of releases of sediment contaminants based on chemical
classes, geographic regions, and industrial categories.  It does  not necessarily indicate where
contaminated sediment problems have occurred and who is responsible. The answers to these
and other questions may be found when the release data is compared to NSI data. This activity
is currently ongoing.

       This section describes how the Point Source Inventory data were prepared for the hazard
analysis and highlights the results  by chemical, geographic area  of release,  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. Four sets of
loading data are available for analysis of sediment hazard potential:  1992 TRI data and three
versions of 1992 PCS data  (based on different treatment  of detection limits).  Most tables and
figures in this section present the results for each set of loads separately. However, the detailed
data in  Appendices B and C are based on a combined set of TRI and PCS loads (with values
below detection set to half the detection  limit).  Appendix  B contains listings  of watersheds
(defined by 8-digit USGS cataloging units) sorted according to HAZREL scores.  Appendix C
contains detailed information on chemicals  associated with  industrial categories, and the industrial
categories with the highest HAZREL scores  in each EPA Region and State.  Although  some
overlap and subsequent double-counting most likely occurred when combining PCS and TRI data,
the combined data  represent a comprehensive set of point source chemical loading information.
Some overlap may have occurred for records of direct surface water releases; overlap may also
have occurred between POTW transfer records in TRI, and POTW discharge records in  PCS.
Overlap was probably greatest for metals and chlorinated aliphatic organic compounds  (e.g.,
triehloromethane) that are included in TRI and are also  frequently regulated in NPDES permits.

4.1.   Preparation of Data for Hazard Analysis

      The first step in conducting the screening level  hazard analysis  was to qualitatively
examine the Point Source Inventory data for validity and prepare the data for analysis. Some of
the original 324 potential sediment contaminants were excluded from the hazard analysis because
PCS and TRI data were unavailable or HAZREL scores could not be calculated. Fifty-eight (58)
chemicals did not have records of surface water releases or POTW  transfers in 1992 from either
                                         4-1

TRI or PCS.  In addition, 57 chemicals did not have sufficient data available to calculate a
sediment hazard score. This group of 57 includes 39 inorganic chemicals without effects-range
data (e.g., beryllium), 9 organic chemicals without K^ values or toxicity data (e.g., toluene
diisocyanate),  6 compound names that represent groups of chemicals whose properties may or
may not be similar (e.g., dichlorobenzenes), and 3 chemicals with very large K^ values relative
to toxicity that lead to unreasonably high equilibrium partitioning estimated sediment chemistry
screening values (e.g., di-n-octyl phthalate with an EqP [1 percent OC] value of 0.44 kg/kg
[parts per part]). An additional 77 chemicals were excluded because their log K^, values are
less than 2 and/or they have alcohol or acid functional groups (e.g.,  acetone). These chemicals
may exhibit polarity  and, therefore, are poor candidates for estimated sediment chemistry
screening value calculation using equilibrium partitioning (and none  had AET values available).
Furthermore,  chemicals  with  low K^ values would not be expected to accumulate  in the
sediment.  Lastly, PCS records of 14 additional  chemicals, such  as malathion and dieldrin,
whose effluent concentrations never exceed their detection limit were  also excluded because there
was no evidence that these chemicals were released from any point  source in the United States
in 1992.  The original list of 324  was thus  reduced to a list of  118 chemicals.   Table A2 in
Appendix A contains a complete list of the 324 potential sediment contaminants, along with
codes identifying the reason for exclusion from the hazard analysis.

       Although systematic checking for errors in the PCS and  TRI data was not performed
when creating the inventory, an attempt was made to eliminate highly suspect records from the
hazard analysis.  Several loading records from PCS were excluded from  the hazard analysis
because they were highly suspect  and would have a dramatic effect on  the hazard analysis.
These records were identified first by sorting facilities by descending aggregate HAZREL score.
The distribution of HAZREL  scores clearly indicated a natural break in  the data at the one
million  HAZREL mark, with  19 facilities exhibiting HAZREL scores more than an order of
magnitude greater the rest of the facilities.  There appeared to be two underlying reasons for
these extremely high HAZREL scores.   The first was the presence of individual chemical
loading records obviously in error (such as a release of several hundred thousand kilograms per
year of dioxin).  Five such records from five separate facilities were excluded.  The second was
chemical loads derived by applying half detection limit values to facilities with very large flows.
This resulted in calculated chemical loading amounts that were, in many instances, several orders
of magnitude  greater than the next highest record  outside of the group of 19. Because these
records represent  loadings that may not  have occurred,  all records from the  remaining 14
facilities were excluded.
                                          4-2

-------
       Over 22,000 individual records of direct or indirect pollutant releases to surface water
from point sources were examined in the screening-level hazard analysis for their potential to
cause sediment contamination.  Releases of 118 different chemicals including metals, halogenated
straight chain (aliphatic) and  aromatic organics  compounds,  organic compounds containing
nitrogen or sulfur  or phosphorus,  pesticides, polynuclear aromatic hydrocarbons  (PAHs),
polychlorinated biphenyls (PCBs), and other organic compounds were analyzed. The 1992 TRI
data have release records for 67 of these chemicals, and 1992 PCS data have release records for
102 of these chemicals. Direct releases from 2,584 facilities classified as major  permittees in
PCS totalled 15,3 million kilograms per year (KGY) in 1992, when values below detection were
set to half the detection limit. Direct  releases from these same facilities were estimated to be 14
million  KGY in  1992 when values below the detection limit were set to zero.  From 1992 TRI
data, direct releases and transfers to POTWs (multiplied by  0.25 to account for removal during
treatment) from 3,218 manufacturing facilities totalled 1.3 million KGY. 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,  Approximately 930 individual watersheds, defined by USGS 8-digit
cataloging  units, receive loads of potential sediment contaminants.   Individual  facilities are
classified into 45 distinct  industrial  categories.  These categories represent a broad range of
activities (e.g., POTWs, chemical manufacturers,  textile mills, coal mines, etc.).

4.2.   Analysis By Chemical

       Table 1 presents the raw loads and HAZREL scores for each of the 67 chemicals included
in the hazard analysis for  TRI data.  The hazard score (i.e., FATE times TOX score)  and the
number of facilities reporting surface  water release or POTW transfer for each chemical  are also
included in Table 1.  Based on TRI data, hexachlorobenzene and ethylene dibromide have the
largest aggregate HAZREL scores, despite being reported by only a few facilities. Table 2 shows
the corresponding information  for the 102 chemicals PCS chemicals analyzed.  Based  on  PCS
data using half  detection  limit, toxaphene, hexachlorobenzene, and  silver have the largest
aggregate HAZREL scores. Based on PCS data, these same chemicals have the largest aggregate
HAZREL scores when using zero for  values reported as below the detection limit.  Table 3
shows the results by chemical for the  combined TRI-PCS  data (PCS  data with values below
detection set to half the detection limit).  Several  chemicals have large aggregate  national raw
loads  and are released from a large number  of  facilities (i.e., nickel,  zinc, copper).  Other
chemicals (e.g., chlordane and heptachlor) appear to represent a few isolated potential problems.

It should be noted that a small number of very large release  records often accounts for the
majority of the national total. Consequently, it is not appropriate to calculate an average facility
HAZREL score by dividing the total HAZREL score by the number of discharging facilities.


       Aggregate  raw loads and HAZREL scores for individual  chemicals are grouped  by
chemical class (e.g., inorganic elements and organics) to determine which types of chemicals
cause the greatest potential sediment hazard (Figures 8, 9, 10, 11, and  12). Organics chemicals
are subdivided into component classes because of the broad range of chemical behavior exhibited.
Classes of  organic compounds are defined primarily  by chemical  structure  and elemental
components, rather than by functional groups (e.g., alcohols, ethers, ketones) or industrial use
(e.g., solvent, reactant, anti-bacterial agent). Industrial use, as well as fate and toxicity properties,
often correspond well with chemical structure.  Chemical class  assignment is made in the
following order:
Metals:
PCB/dioxins:
PAHs:


Pesticides:


Organic (N,S,P):



Halogenated:


Organic (C,H,O):
This group comprises metal species that have effect range values described
in Section  2.1.1. and whose presence in water in significant quantities is
largely from anthropogenic sources.

This   group    includes   7    polyehlorinated   biphenyls;   2,3,7,8-
tetrachlorodibenzo-p-dioxin; and 2,3,7,8-tetrachlorodibenzofuran.  These
compounds are highly toxic, highly bioaccumulative, and highly persistent.
Records of point source releases come solely from PCS.

This group includes all polynuclear aromatic hydrocarbons, including those
that are halogenated.

This  group includes chemicals that are  usually  large,  complex, and
manufactured to be biological inhibitors.

This group has nitrogen, sulfur, or phosphate components that make their
function  and chemical behavior distinct from  other organic chemicals.
These chemicals may also be halogenated.

This group contains  aliphatic, alicyclic, or aromatic chemicals that  have
one or more chlorine, fluorine, bromine, or iodine constituents.

This group contains  all remaining organic chemicals of interest.  These
chemicals can be straight chain or branched aliphatics, 5 or 6 member
alicyclics, or aromatic compounds.  All of these chemicals are composed
solely of carbon, hydrogen, and oxygen.

       Figure 8 depicts raw loads and HAZREL scores by chemical class for TRI data.  TRI data
show that halogenated organics and C,H,O organics each account for over a third of the raw load,
yet halogenated organics account for nearly three-quarters of  the HAZREL score and other
organics represent only 1 percent of the HAZREL score.   Figure  8  also  shows the strong
sediment hazard potential of pesticides, which account for less than 1 percent of the raw load,
but 13 percent of the HAZREL.  On the other hand, elements and PAH compounds both have
a greater percentage of the raw load (11 percent each) than the HAZREL score (5 percent each).
N,S,P  organics have approximately the same contribution to total raw load (3 percent) and
HAZREL score (4 percent).

       Figures 9, 10,  and  11  depict raw loads and HAZREL scores by chemical class for the
three sets of PCS data. The major difference between TRI and PCS is dominance of metals as
a proportion of the total raw load  (69 percent).  The hazard potential  relative to raw  load
increases for pesticides and halogenated organics, and decreases for metals; C,H,O organics; and
PAHs. In addition, PCB/dioxins exhibit a strong hazard potential (6 percent of the total) relative
to raw load (less than 1   percent of the total).  The hazard potential of PAH compounds is
minimized in these analyses because the chemicals that comprise this class have very large K^,
values, and the equilibrium partitioning model thus assumes they will be tightly bound to solid
particles and, therefore, not be bioavailable to a great extent.

       Figures 9, 10, and 11 also show that while chemical class proportions of total raw load
remain fairly constant for each treatment of values  below detection, the  proportions  of total
HAZREL score change greatly.  In particular, the importance of pesticides;  PCB/dioxins; and
N,S,P organics increases at the expense of metals and halogenated  organics when values below
the detection limit are set to half the detection limit or set equal to the detection limit.  This is
because pesticides; PCB/dioxins; and N,S,P organics tend to have large sediment hazard scores
are more likely to be below detection than the constituents of other groups. It is interesting to
note that when values below detection are set to half the detection  limit, the raw load increases
nearly  10 percent from 14.0 million (kg/yr) to 15.3 million (kg.yr), whereas the total HAZREL
score increases 250 percent from 1.4E+6 to 4.9E+6, This clearly indicates the importance of data
derived from nondetections. Figure 12 depicts raw loads and HAZREL scores by chemical class
for the combined TRI-PCS data. The distribution of combined TRI-PCS HAZREL scores differs
only slightly from the distribution based on PCS HAZREL scores alone because PCS release data
and HAZREL score accounts  for the vast majority of combined TRI-PCS  releases (92 percent)
and HAZREL score (97 percent).

4.3.    Analysis By Geographic Area

       To evaluate geographic areas of concern, HAZREL scores are grouped by United States
Geological Survey (USGS) hydrologic unit codes.  USGS assigns 8-digit hydrologic unit codes
to all watersheds  in the United States.  These hydrologic unit codes  represent four levels of
organization: regions,  subregions, accounting units, and cataloging units. The first two digits
represent the region.  USGS divides the continental United  States into  18 distinct hydrologic
regions based on river drainage.  Figure 13 depicts the boundaries of each USGS region.  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, HAZREL scores are sorted geographically
according to USGS region (2-digit code), accounting unit (6-digit code), and cataloging unit (8-
digit code).

       In general, areas that are population centers and are  associated with  industrial activity
receive the greatest amount of potential sediment contaminants from  point sources.  Table 4
presents HAZREL scores summed by USGS region, based on TRI data.  The Lower Mississippi
accounts for more than two-thirds of the total national HAZREL score. Loading records of three
chemicals from three facilities comprise  80  percent  of  the HAZREL score in  the Lower
Mississippi:  a release  of 86 kilograms of hexachlorobenzene from an inorganic chemical
manufacturer into the Lower Calcasieu  in Louisiana,  a release of 45 kilograms of ethylene
dibromide from a petroleum refinery to Bayou Sara-Thompson in Louisiana, and a POTW
transfer of 39 kilograms of chlordane from an organic chemical  producer into the Wolf in
Tennessee. However,  without these releases, the Lower Mississippi would still have the largest
percentage of HAZREL (30 percent). The Great Lakes and South Atlantic-Gulf regions also have
relatively large HAZREL scores. Regions with relatively low HAZREL scores include the Upper
Colorado, the Souris-Red-Rainy, and the Great Basin.

       Tables 5, 6, and 7 present HAZREL score summed by USGS region, based on the three
sets of PCS data using different treatment of detection limits.  California, the Lower Mississippi,
the Mid-Atlantic, and  the Texas-Gulf have the highest  HAZREL scores in the nation based on
PCS data. However, the relative proportions change depending on treatment of values below
                                         4-20

detection.  California accounts for 11 percent of the HAZREL score using zero for values below
detection, but accounts for 46 percent of the HAZREL score using half the detection limit for
these  values.  Likewise,  the Great  Lakes and Mid-Atlantic  also  increase in  proportion of
HAZREL score when half the detection limit is assumed.  In contrast, the Lower Mississippi,
Texas-Gulf,  South Atlantic-Gulf, and New England regions all decrease in  proportion of total
HAZREL when half the detection limit is used for non-detectable pollutants. Table 8 presents
the HAZREL  score summed by  USGS  region,  based on combined TRI-PCS  data.  The
distribution of combined TRI-PCS HAZREL  scores differs only slightly from the distribution
based on PCS HAZREL scores alone because PCS release data and HAZREL score accounts for
the vast majority of combined TRI-PCS releases (92 percent) and HAZREL  score (97 percent)

       To graphically depict the distribution of point source releases of sediment contaminants
in the United States on a smaller scale, HAZREL scores were summed  at the 6-digit accounting
unit level river drainage basins.  Figures 14 and 15 depict 6-digit accounting units in the United
States, grouped into quartiles,  according  to  HAZREL  scores for TRI data and  PCS  data,
respectively. The 4th quartile represents the highest HAZREL scores,  whereas the 1st quartile
represents the lowest scores. Areas that are blank do not receive any load of potential sediment
contaminants from point sources, according to TRI and PCS records.  The geographic areas with
the greatest HAZREL scores based on TRI data and PCS data are in relatively good agreement
with each other. River drainage areas in the Mid-Atlantic coast, Southern Piedmont, Gulf coast,
Great Lakes, Ohio Valley, California coast, and northwest Washington State have the largest
HAZREL scores and, therefore, may  be most likely to  have contaminated sediment from point
sources. The areas with the greatest HAZREL scores based on TRI data are located primarily in
manufacturing  centers. The areas with the greatest HAZREL scores from PCS data are  located
in population centers and highly industrialized areas.

4.3.1.  Watersheds  of Greatest Concern in the Nation

       For the purposes of this study, the term "watershed" is applied to the area defined by the
USGS 8-digit  cataloging  unit.   According to PCS  and TRI  records and  reach assignments
evaluated for this analysis,  930 distinct watersheds that  receive  potential sediment contaminants
from point sources.  Facility level, chemical-specific HAZREL scores  from  PCS and TRI data
were summed by USGS cataloging unit (CATUNIT) to derive a total watershed HAZREL score.
The distribution of watershed HAZREL scores were divided into quintiles with the upper 20
                                         4-26

percent of values (i.e., watersheds with the highest HAZREL scores) identified as "Priority Group
1",  The remaining values were identified  as priority groups 2, 3, 4, and 5.  A priority group
classifies watersheds according to  priority  of conducting further  assessment as  well  as
identification and implementation of effective management efforts such as those described in
Chapter 5.  A watershed classified into priority group 4 or 5 does not indicate that the watershed
does not receive point  source releases of sediment contaminants, only that this analysis using
these data does not indicate substantial potential risk from point sources subject to major NPDES
permits  or TRI reporting in 1992.

      Watershed priority groups are presented in Appendix B of this report, sorted by EPA
Region,  State, and USGS cataloging unit.  Watersheds  that  cross State  and EPA  regional
boundaries  were  assigned to the State where the facilities contributing the most to the HAZREL
score  are located.  The industrial category and chemical class  that contribute the most to the
HAZREL  score  are  also  provided.    POTWs  are  the dominant  industrial category  in
approximately 41 percent of the priority group 1 watersheds. Organics chemical producers, pulp
and paper mills, and inorganic chemical producers are the greatest contributors to HAZREL
scores in 21  percent, 9 percent, and 4 percent of priority group 1 watersheds, respectively.
Releases of metals are  the dominant chemical class in almost half (47 percent) of the  priority
group watersheds, with  halogenated organic compounds dominating in 22 percent.  Pesticides and
PCB/dioxins are the greatest contributors to HAZREL score in 14 percent  and  10 percent of
priority  group 1  watersheds, respectively. Priority group 1  includes several  watersheds  that are
known or suspected to have contaminated, such as the Hudson-Raritan estuary in New York/New
Jersey, the Schuylkill and Lower Delaware  rivers in Pennsylvania/New Jersey, the Detroit River
in Michigan, the Calcasieu Estuary in Louisiana, and San Francisco Bay.

4.3.2. Watersheds of Greatest Concern in EPA Regions and States

      The screening level hazard analysis indicates that  the pattern  of releases of sediment
contaminants varies by EPA Region. Table 9 shows the number of watersheds in each priority
group by EPA Region  based on the combined PCS-TRI data presented in Appendix B.  Over
one-quarter (26 percent) of all priority group 1 watersheds are located in EPA Region 4. Large
proportions of priority  group 1 watersheds  are also located in Region 6(17 percent), Region 5
(16 percent), Region 2  (11 percent), and Regions 9 and 3 (10 percent each).  Although Regions
2, 4, 5,  and 6 contain  large numbers of priority 1 watersheds, these regions also contain the
largest total number of watersheds, and the priority group totals are fairly evenly distributed.  In
                                          4-30

contrast, Region 2 contains only 5 percent of the total number of watersheds examined in this
analysis,  yet  over 80 percent of them (40 out of 48) are  listed  in priority groups 1 or 2.
Likewise, one-third of all watersheds in Region IX (19 out of 56) are listed in priority group 1.
On the other hand, watersheds in  Regions 1,  7, and 8 tend to be  listed in the lower priority
groups.  Watersheds  in Region 10 tend to be either medium-high  priority (one-third listed in
priority group 2)  or  low priority  (one-third  listed  in priority group 5).   At the  State level,
California (9 percent), Texas  (9 percent), New York (6 percent), Georgia (6 percent), Louisiana
(5 percent), Tennessee (5 percent), and Pennsylvania (4 percent) have the largest percentages of
watersheds in priority group  1.

      Appendix B lists the  watersheds of greatest concern  in EPA Regions and States.  The
tables in Appendix B indicate that the dominant chemical class discharged and industrial category
responsible for these  discharges within watersheds tend to be metals and POTWs respectively.
However, this does not hold  true for many of the watersheds with the largest HAZREL  scores
in priority group  1.   In the two  following  paragraphs, the dominant industrial  category or
chemical class is stated in parenthesis if it differs from POTWs or metals.

      The watersheds with  the  highest HAZREL scores in  EPA Region  1  include the Lower
Connecticut (metal products and machinery) and Quinnipiac in Connecticut and the Narragansett
in Rhode  Island.   The watersheds  with  highest HAZREL score  in EPA Region 2 are the
Hackensack-Passaic and Sandy Hook-Staten Island in metropolitan New York/New Jersey and
the Niagara (PCB/dioxins and metal products and machinery) and Lower Genesee (halogenated
organics and photographic equipment) in upstate New York. Notable watersheds in EPA Region
3 include the Patuxent in Maryland (pesticides), the Lower Delaware in Pennsylvania/New Jersey
(N,S,P organics), and the Lower James in  Virginia (halogenated organics and organic chemical
producers). The Mobile-Tensaw in Alabama (PCB/dioxins and pulp and  paper mills), the Lower
St. John's in Florida (pulp and paper mills), and the Pigeon in North Carolina (PCB/dioxins and
pulp and paper mills)  are among the watersheds with the highest HAZREL scores in EPA Region
4.  In EPA Region  5, watersheds with the highest HAZREL scores  include the Detroit in
Michigan and the  Manitowoc-Sheboygan (PCB/dioxins) and Milwaukee  (pesticides) watersheds
in Wisconsin.  In EPA Region 6, most of the coastal drainage watersheds in southern Louisiana
(mostly  from  halogenated organics  and  organic  chemical producers) have relatively high
HAZREL scores, as do the Little Cyprus (PCB/dioxins and warehousing and storage), Cedar, and
Sabine Lake (pesticides) watersheds  in Texas. Watersheds with the most significant HAZREL
scores in EPA Regions 7 and 8 are the Middle Arkansas-Slate in Kansas and  the Lower Belle
                                         4-32

Fourche in Montana/South Dakota (fertilizers). Most of the top watersheds in EPA Region 9 are
located in  the San Francisco Bay area and on the southern  California coast (dominated by
pesticides in both areas). The most notable watershed in EPA Region 10 is the Lower Columbia-
Clatskanie in Oregon (PAHs and nonferrous metal producers).

4.4.   Analysis by Industrial Category

       Facility level HAZREL scores for chemical releases were sorted by industrial categories
according to the primary SIC code reported in PCS or TRI,  There are 46 industrial categories
overall, covering a broad range of activities. A relatively small number of  TRI facilities (13),
but a significant  number of PCS facilities (314), do not fall into the defined industrial categories
or do not report  a primary SIC code. These facilities are listed as  "Not Classified".  Table 10
lists these industrial categories by descending HAZREL score for TRI data.  Table 11 presents
the same information for PCS data for the three different treatments of values below detection.
Table  12 presents the results by industrial category for the combined TRI-PCS data.  For TRI
data, inorganic chemical producers have the highest HAZREL scores, followed by petroleum
refineries, organic chemical manufacturers, photographic equipment, pulp and paper mills, and
pesticide manufacturers  (Table 10).  The majority of the total raw load for inorganic chemical
producers, photographic equipment, pulp and paper, and pesticides is from direct surface water
releases, whereas the majority of total raw load  for petroleum refineries and organic chemical
manufacturers is  from POTW transfers. For PCS data, POTWs, organic chemical manufacturers,
pulp and paper, and metal products and machinery are the highest ranked industrial categories
regardless of treatment of values below detection (Table 11).  Using half the detection limit,
warehousing and storage, iron and steel, inorganic chemical  producers, Pharmaceuticals, metal
finishing, and fertilizers round out the top ten.  Using  zero for values below  detection, the
HAZREL scores  for warehousing and storage, pharmaceuticals, and inorganic chemical producers
are substantially  reduced.  The distribution of combined TRI-PCS HAZREL scores (Table 12)
differs only slightly from the distribution based on PCS HAZREL scores alone (at half detection
limit) because PCS release data and HAZREL score accounts for the vast majority of combined
TRI-PCS releases (92 percent) and HAZREL score (97 percent).

       A relatively large release of a hazardous chemical from a single facility can result  in a
high HAZREL score for an industrial category. For example,  a single TRI release record of 1,2-
dichloropropane  from a manufacturing facility  in upstate New York accounts for 96 percent of
the HAZREL score for photographic equipment. Likewise, PCS loading records derived from
                                         4-33

using half detection limit values for a set of seven PCBs from a facility in Texas account for 68
percent of the HAZREL score for warehousing and storage. Table Cl in Appendix C presents
HAZREL scores grouped by chemical for each  industrial category.  The number of facilities
within the industrial category discharging each chemical is also presented in Table Cl.  Note, this
table is not a comprehensive list of all chemicals discharged from all facilities, but is limited to
industrial category-chemical combinations where the HAZREL scores exceed 1.

       Table 13 presents the number of facilities  in each industrial category by data source (i.e.,
PCS or TRI). The majority (42 percent) of PCS facilities included in the hazard analysis are
POTWs, with organic chemical manufacturers, petroleum refineries, and pulp and paper mills also
well represented. The majority of TRI facilities (48 percent) are organic chemical manufacturers
and metal working operations. Some industrial categories are not well represented in either PCS
or TRI. These include asphalt products, hospitals, ink, leather goods, and tobacco products. 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 reporting requirements for TRI, or not having release records for pollutants retained
in the hazard analysis.

4.4.1.  Industrial Categories of Greatest Concern in the Nation

       The top industrial categories in the Nation according to HAZREL score for TRI data, PCS
data, and combined TRI-PCS data are depicted in Figure 16. The distribution of combined TRI-
PCS HAZREL scores  differs only slightly from the distribution based on PCS HAZREL scores
alone because PCS release data and HAZREL score accounts for the vast majority of combined
TRI-PCS releases  (92 percent) and HAZREL score  (97 percent).  The industries of greatest
concern in the Nation, based on TRI data, are inorganic chemical producers,  petroleum refineries,
and organic  chemical  manufacturers.   Together, these  three industries account for over three
quarters of the total HAZREL score. Other significant industrial categories based on TRI data
are photographic equipment (4 percent of HAZREL), pulp and paper (3 percent of HAZREL),
and pesticides (3 percent of HAZREL).  Based on PCS data using half detection  limit values,
releases from POTWs  account for approximately  61 percent of the total HAZREL score.  Other
industrial  categories  of  greatest concern on  a  national scale include organic  chemical
manufacturers (11  percent of HAZREL), pulp and paper (3 percent of HAZREL), and metal
products and  machinery (2 percent of HAZREL).

       A major difference between PCS and TRI is the way transfers to POTWs are handled.
Chemicals loads that  are identified as POTW transfers in TRI are attributed to the facility
producing the waste,  whereas chemicals discharged by POTWs in PCS  are attributed to the
POTW itself. Thus, releases are identified at the point of actual release, rather than the point of
production.  Waste discharged from a POTW may have numerous sources that are not classified
by industrial category because  it is not possible to trace the original source of chemicals
discharged from POTWs from PCS data. Likewise, it is not possible to  identify the ultimate
destination of POTW  transfers from TRI data.  Given this distinction, the industrial categories
identified on the PCS pie chart in Figure 15  can be  interpreted as the largest dischargers of
potential sediment contaminants, whereas the industrial categories identified on the TRI pie chart
on Figure 15 can be interpreted as the  largest producers of potential sediment contaminants,

4.4.2.  Industrial Categories of Greatest Concern in EPA Regions and States

       Tables C.2 and C.3 in Appendix C list the industrial categories in each EPA Region and
State  with HAZREL  scores greater than 1  based on PCS and TRI data combined. The top
industrial categories in the Nation are  usually also among the top  industries in EPA  Regions.
POTWs are  the  predominant industrial category in the nation  as  a whole and in  most EPA
Regions. However, metal products and machinery has the largest HAZREL score in Region 1,
pulp and paper has the largest  HAZREL score in Region 4, and fertilizers have  the largest
HAZREL score in Region 8. The top industrial categories in individual States often differ from
the highest ranked national industries and may reflect dominant industrial activities in that State.
For example, pulp and paper, organic chemicals, soaps and  detergents, Pharmaceuticals, and
textiles are the top five industrial categories in North Carolina. Timber and explosives are among
the top five industries  in Arkansas.  Food and kindred products are relatively important potential
sources of sediment contaminants in Maryland and Colorado. Pesticides and pulp and paper are
important industries of concern in Georgia. In Connecticut, metal products and machinery is the
dominant industry. Adhesives and sealants have the third largest HAZREL score in Michigan
(behind POTWs and organic chemicals).  The top industry in New Mexico is nonferrous metals
in terms of release of  sediment contaminants.

4.5.    Conclusions

       Over 22,000 individual TRI and PCS records of point source pollutant releases of 118
different chemicals are included in the hazard analysis for the year 1992.  Approximately 930
                                         4-40

-------
individual watersheds and 46 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.  Regional rankings based on geographic
assignment of loading data suggest that some USGS hydrologic regions, particularly the Lower
Mississippi and California regions, may have higher potentials for sediment contamination than
lower-ranked regions. The Lower  Mississippi, Great Lakes, and South Atlantic-Gulf hydrologic
regions account for nearly 85 percent of the total TRIHAZREL score for the United States. The
California, Mid-Atlantic, Lower Mississippi, Great Lakes, and Texas Gulf hydrologic regions
account for nearly 85 percent of the total PCS HAZREL score for the United States.  At the
hydrologic region  level, the distribution  of  combined TRI-PCS HAZREL scores differs only
slightly from the distribution based on PCS HAZREL scores alone because PCS release data and
HAZREL score accounts for the vast majority of combined TRI-PCS releases (92 percent) and
HAZREL score (97 percent). However, at smaller units of aggregation, such as USGS cataloging
units  (or watersheds), the combined TRI-PCS data provide  the most comprehensive set  of
sediment contaminant release information. HAZREL scores for individual watersheds indicate
that EPA Regions  4 and 6 contain the most river drainage areas identified as high priority for
further assessment.

       The results of analyses indicate that certain chemical classes and industrial categories have
higher potentials for contributing to sediment contamination than others.  Both TRI data and PCS
data demonstrated the significant sediment hazard potential of pesticides and halogenated organic
compounds. Despite the inherent differences in the TRI and PCS data bases, a relatively good
correlation exists between the ranking of industrial categories based on HAZREL scores.  This
supports the conclusion that the highest ranked industrial categories contribute the most sediment
contaminants.   Based on TRI  data, inorganic chemical producers, petroleum refineries, and
organic chemical manufacturers account for over three quarters of the total TRI HAZREL score.
Other significant industrial categories based on TRI data are photographic equipment (4 percent
of TRI HAZREL score), pulp and paper  (3 percent of TRI HAZREL score), and pesticides  (3
percent of TRI HAZREL score). Based on PCS data using half detection limit values, releases
from POTWs, organic chemical manufacturers, pulp and paper mills, and metal products and
machinery producers account for  approximately 61,  11, 3,  and 2 percent of the  total  PCS
HAZREL score, respectively. As with the analysis by geographic region, the distribution  of
combined TRI-PCS HAZREL scores among  industrial  categories differs only slightly from the
distribution based on PCS HAZREL scores alone because PCS release data and HAZREL score
accounts  for the vast majority of combined  TRI-PCS  releases and  HAZREL  score.  The top
                                        4-41

-------
industrial categories in the nation are usually also among the top industries in EPA Regions.
However, the top industrial categories in individual States often differ from the highest ranked
national industries and may reflect dominant industrial activities in that State.

       It is  important to note that  the aggregate data used in  this study are not  necessarily
indicative of widespread problems associated with particular chemicals, regions, or industrial
categories.   For example, the data indicate that highly  toxic pesticides (such as chlordane,
heptachlor, and  toxaphene) and  PCB/dioxins dominate  the HAZREL on a national  level.
However, these large  HAZREL scores may be a result of releases from only  a few individual
facilities.  This  may  indicate a localized problem, but  not a  national or regional  problem.
Alternatively, a large national total could be the result of nearly ubiquitous releases, distributed
throughout  the entire Nation that never reach significant  levels at any  one location.   The
HAZREL and raw load data for copper illustrate this. It is released in large amounts across the
Nation, but does not have a high hazard score relative to other chemicals.

       It is  also  important to recognize  that the geographic areas  identified in this analysis
represent areas where the potential  for sediment contamination  exists; they do not  represent
specific locations where sediment contamination has occurred.  For example, USGS cataloging
units can represent large areas encompassing large mainstream rivers and small tributary streams
that vary greatly in  size, shape,  and physical/chemical  characteristics.  Transport,  sediment
partitioning, and sediment accumulation in locations either very  close to the point of discharge
or  far downstream  depend  on  many  factors,  including  streamflow,  stream  velocity,
hydromorphology, particle size distribution and organic carbon content of underlying sediment,
suspended sediment load, temperature, pH, and salinity.

       HAZREL scores alone cannot  predict sediment contamination, nor can they be used as
the sole basis  for any regulatory action or allocation of resources.  However,  HAZREL scores
can be used  to  prioritize chemicals,  areas,  and industries  to initiate actions to obtain  more
information about potential sediment contamination and its source(s). Comparison with existing
sediment monitoring  data or additional sediment monitoring should be initiated to confirm the
results of these analyses.

       The study indicates, however, that releases of sediment contaminants are  currently
ongoing and likely contributing to the  formation of contaminated sediments. The percentage of
point  source loadings relative to the total amount of sediment contaminants being  released to
                                          4-42

-------
waterbodies and the impact of these loadings to the health of the Nation's aquatic ecosystems are
issues currently being addressed by EPA's Office of Science and Technology.  These and other
ongoing  activities related to the  assessment and  management of contaminated  sediments,
including prevention, are described in the final chapter of this report.

5.0.    SELECTED APPLICATIONS OF POINT SOURCE INVENTORY DATA

       As described previously, the Point  Source Inventory is only one component of EPA's
Contaminated Sediment Management Strategy. An inventory of potential nonpoint sources of
sediment contaminants has already been initiated and will add significantly to the understanding
of the processes which contribute to the  formation of contaminated sediments.   Potentially
significant nonpoint sources include urban  and agricultural runoff, atmospheric deposition, and
other sources.  An assessment of the  hazard potential from nonpoint sources will  assist in
evaluating the  relative  importance  of  point  and  nonpoint  sources, and will enable  further
identification of geographic areas  of concern.  In addition, the ongoing National Sediment
Inventory of contaminated sites represents an attempt to gather and assess available site-specific
sediment quality data.  Managing contaminated sediments is a challenging task because of the
complexities associated  with  the fate and transport of environmental  contaminants, and  the
difficulties in assessing  historical  and current sources  of sediment contamination. However,
source inventories  such as this, along with other contaminated  sediment program initiatives,
represent progress toward the development of tools that can assist EPA in making regulatory and
remediation decisions with regard to sediment contamination.

       Several uses of Point Source Inventory data are described  below to provide  examples of
how these data  can contribute to specific EPA and State regulatory activities.  These examples
include a description of how Point Source Inventory data will be  integrated with data compiled
for the National Sediment Inventory of contaminated sites (Section 5.1); how the data when
grouped by industrial category, and further  grouped by chemical within industrial category, can
assist OST in screening industries for effluent guidelines  development (Section 5.2); how the data
can be used  by the Office of  Enforcement (OE) identify potential discharges and/or industrial
activities that may be contributing to fish  advisories (Section 5,3); and how a State or EPA
Regional NPDES permitting authority could potentially  incorporate Point Source Inventory data
in the initial stages of reissuing permits and establishing monitoring requirements (Section 5.4)
for specific industries.

5.1.    Sed|ment Monitoring Uses

       Concurrent  with development of the  Point Source  Inventory,  OST is developing a
nationwide inventory of contaminated sediment sites. Both the Point Source and Site Inventories
are two of three components  of the National  Sediment Inventory (NSI), the third component
                                          5-1

-------
being the Nonpoint Inventory currently under development.  OST initiated development of the
NSI in response to objectives set forth in EPA's Contaminated Sediment Management Strategy
and EPA's mandate  under the  Water Resources Development Act of 1992 (WRDA),   The
information from the evaluation of the NSI will be used to assess the nature  and extent of
sediment contamination of the Nation's freshwater and estuarine ecosystems. The results of this
study will be presented to Congress in 1995. NSI data will be used to assist EPA in assessment,
pollution prevention, remediation, and dredged  material management activities by  making
available pertinent background information so that EPA program managers and  others can be
more  effective.

       The data  in Site  Inventory are being compiled  from several sources, including EPA's
STORET ambient monitoring data  base, NOAA's National Status and Trends data base, the U.S.
Fish and Wildlife Service, the U.S. Army Corps of Engineers, the U.S. Geological Survey, and
EPA Regional and Program Offices (e.g., EMAP, GOMP, Regions 4, 5, 6, 9, 10, and others).
The minimum data elements required for study data to be included are the data source (citation),
sampling year, latitude/longitude coordinates,  and sediment chemistry  or  tissue  residue data.
Because WRDA  mandates a Report to Congress every two years, sediment quality and pollutant
source data contained in the NSI will be contimually updated and improved over time. Although
the NSI database will ultimately reside on  the modernized STORET system, the NSI database
(in SAS files or  dBASE format) will be  available from OST to  interested individuals  in July,
1995.

       Point Source Inventory data have been incorporated into the NSI database to  provide
potential users with access to information on current point sources of sediment contamination.
The  data  elements  of  the  Point  Source Inventory include   facility   name,  city, State,
latitude/longitude, NPDES or TRI identification number, primary  SIC code, OW industrial
category, chemical name, CAS number, annual load, and known or likely receiving waterbody,
recorded as the 8-digit USGS cataloging unit and 3-digit segment number.

       While the NSI will help  document previously examined locations,  OST anticipates that
significant sediment contamination may also exist in locations where no sediment quality data
currently are available. The Point Source Inventory can  thus be an important tool for identifying
candidate locations for sediment monitoring.  Where sediment quality data exist,  knowledge of
existing sources of sediment contamination may  be able to help  distinguish between sites that
have  been  contaminated by  historical  sources  or spills  and sites that  are currently being
                                          5-2

-------
contaminated  by active  sources.  This  knowledge  may  be useful  in  selecting appropriate
remediation activities.

       An initial comparison of the Point Source Inventory data with  Site Inventory data gives
a preliminary indication that data gaps exist. For example, the Site Inventory shows that many
sediment  monitoring stations exist in the western part of North  Dakota.  The Point Source
Inventory, however, indicates few point sources in these areas, suggesting that nonpoint source
discharges may be responsible for any sediment contamination detected in this area,  A future
examination of similarities between nonpoint source inputs of specific chemicals and elevated
levels of these same chemicals in sediment may lead to the same  conclusion and assist in the
identification of potential management approaches.  Conversely,  the Point Source  Inventory
indicates that large chemical loads are being released in northern  Minnesota, Indiana,  and the
central portions  of Georgia and Alabama.   The Site Inventory indicates that few monitoring
stations exist in these areas. Therefore, resources could be focused on increased sediment quality
monitoring in these areas.

       Another monitoring activity where the  Point Source Inventory can be useful is in the
dredged material disposal management program. The Evaluation of Dredged Material Proposed
for Ocean Disposal - Testing Manual ("Green Book") (U.S. EPA and U.S.  Army, 1991), outlines
a tiered approach to evaluating dredged material prior to disposal.  The Point Source  Inventory
can provide useful information to EPA and the Corps of Engineers (COE) program managers for
conducting a Tier  1  Evaluation, the  review of background information and identification of
chemicals of concern for further assessment.

       Another environmental program using sediment monitoring  data is the National Estuary
Program  (NEP). Congress established this program as part  of the 1987 Clean Water Act to
identify nationally significant estuaries and to improve and protect their water quality and living
resources.  The NEP now encompasses 21 estuaries on the Atlantic,  Pacific, and Gulf coasts.
The majority of NEP estuaries have identified toxic contamination as a primary threat, and have
recommended sediment monitoring. Future research needs identified in EPA's 1992 draft Report
to Congress on the NEP include the  problem of contaminated sediments and their impact on
benthic  communities.   Existing NEP  Management  Conferences  can use  the  Point  Source
Inventory to help identify potential sources of contamination and to help formulate specific plans
in their Comprehensive Conservation and Management Plan (CCMP).  Point Source Inventory
                                          5-3

-------
data can also assist in identifying prospective estuaries of concern for consideration as future
NEPs.

5.2.   Effluent Guidelines Development Uses

       Point Source Inventory data can be used to assist OST in screening industries for selection
for national technology-based effluent guidelines development and  to help  identify specific
chemicals to be addressed by those  regulations.   The effluent  guidelines process involves
developing and evaluating treatment options to be  designated as Best Available Technology
(BAT), Best Conventional Technology (BCT), and Pretreatment Standards for New and Existing
Sources (PSNS and PSES).  The Point Source Inventory can be  used as a screening tool for
selecting industries by ranking industrial categories according to potential sediment hazards.  It
can also be used to assist in technology option development and selection by providing additional
background information on persistent  chemicals  causing the greatest risks to aquatic life and
human health.
       Several industrial categories for which loading data from PCS and TRI exist are currently
undergoing preliminary studies to determine the need for national effluent guidelines.  Table 14
lists these industries and their associated raw loads and HAZREL scores from analysis of the
PCS and TRI data bases.  Point Source Inventory data indicate that all of these industries, with
the exception of leather tanning,  are potentially important sources of sediment contamination.
It should be noted that the Point Source Inventory does not enable a full and complete assessment
to be made of the  potential hazards and risks from chemical releases  by these industries, but it
can be useful in screening-level analyses.

5.3.    Pollution Prevention and Remediation Uses

       State advisories limiting fish consumption and/or other uses by the general public due to
contamination by toxics have been issued for many of the nation's waterbodies.  Contaminants
responsible for these advisories can be linked to point and nonpoint source releases, including
sediments. The Point Source Inventory  can be used to identify potential sources of sediment
contaminants for a given watershed by providing information on nearby or upstream dischargers.
Further, the Inventory can provide data on  specific chemicals that are likely to cause adverse
environmental  impacts.   This can provide EPA's  Office of Enforcement and  Compliance
Assurance (OECA) with the information  necessary to identify potential discharges or industrial
activities that may be contributing to the water quality advisory.

       The Point Source  Inventory can  be used to identify potential discharges  of sediment
contaminants that may contribute  to existing fish advisories. However, it is important to realize
that the Point Source Inventory alone does not contain all the information necessary to identify
the potentially  responsible parties.  Instead, it  can be used to  provide an  initial indication of
possible facilities  and to  indicate a direction  for the subsequent investigation of other data
sources.

       The following steps outline an approach for using the Point Source  Inventory data base
to screen potentially responsible parties:

       «      Examine EPA's fish advisory data base to identify chemical, State, EPA  Region,
             waterbody,  and identification  number for each advisory of interest;

       *      Assign the appropriate  CAS  number(s) to  the chemical names used in the
             advisories;

       •      Query the Point Source Inventory data base for facilities discharging that chemical
             (identified by CAS number in data base);

       •      Produce reports listing the CAS numbers, chemical names, facility identification
             numbers, facility names, city, State, and river reach  number;

       »      Inspect the reports to identify potential facilities (i.e., the  same watershed as
             indicated in the fish advisory  or an upstream watershed) and to eliminate others
             from further consideration (i.e., downstream location  or entirely  different river
             drainage system); and
                                           5-5

-------
              Investigate further the final list of potential facilities using other information
              sources.
       For example, Table 15 indicates current fish advisories for mirex and hexachlorobenzene.
Relevant information  from the advisories can be compiled,  and CAS numbers assigned to the
chemicals. After examining drainage patterns on a USGS map of 4-digit hydrologic subregions,
an ad-hoc query can be performed using Microsoft Access® to list all dischargers of mirex in
USGS region 04  (all  dischargers in the Great Lakes  region  could potentially affect the
waterbodies listed on  Table 15), and all dischargers of hexachlorobenzene in USGS subregions
0410 (the only subregion that could affect the Ashtabula River) and 0808 (the only subregkm that
could affect the Calcasieu Estuary and Bayou D'Inde).

       Additional information will likely be needed to further investigate the final list of suspect
facilities based on the Point Source Inventory. A partial list of these sources and the information
contained within each include:

       •      TRI — The Toxic Release Inventory may be searched on-line to confirm the data
              in the Point Source Inventory and to  identify releases of the chemical to other
              media.

       •      PCS — The  Permit Compliance  System  may  be searched on-line to gather

              FINDS — The Facility Inventory System may be searched interactively to identify
              other  EPA program  offices  that  have permitted the facility and  to obtain
              information about the  owner of the facility.

              WQAB  — A  set of mainframe interactive procedures developed and maintained
              by the Monitoring Branch of the  Assessment Watershed Protection Division.
              Especially useful are  the procedures  RCHDAT (to retrieve reach numbers for
              NPDES  facilities) and PATHSCAN  (to  retrieve  information  on NPDES and
              drinking water utilities located upstream or downstream from a specific location).

              ReachScan — A PC-data base and program developed and maintained by OPPT
              functions in a similar manner to  PATHSCAN, allowing the retrieval of upstream
              and downstream utilities relative to point source dischargers.
5.4.   Sediment Permitting Uses

       The Point Source Inventory can be used, in conjunction with the NSI, as a screening level
tool to identify current contaminant sources nearby or upstream from sediment with elevated
pollutant levels.  Permit issuing authorities can then target these facilities for further assessment.
States  and EPA  Regional  Offices would have the  most practical use for the  point  source
inventory in helping to decide which watersheds and facilities should be the focus  of permitting
efforts.   EPA Headquarters  can also  use  the  Point Source Inventory and NSI to identify
watersheds and facilities where procedures for developing sediment quality-based  permit limits
can be tested or demonstrated, to identify problem pollutants, and to evaluate whether current
point source  permit  limits  are  sufficiently protective  of human  health  and  the  aquatic
environment, including sediments.

       Potential  permitting uses of Point Source Inventory data are  possible.   The NPDES
program  offers a specific example of how these data can be used by a regulatory authority. In
many cases, EPA Regional Offices delegate NPDES permitting activities to individual  States.
The State of North Carolina is  a delegated State that has  reorganized its permit reissuance
schedule such that all permits in a given river basin come up for renewal in the same year. This
schedule offers many opportunities for coordinating permitting and  monitoring efforts and also
allows the State to examine  cumulative  pollutant  load issues, such as downstream sediment
contamination.   As an example,  suppose dischargers within a specific river basin in North
Carolina  are due for renewal of NPDES permits.  As part of the initial analysis, the water quality
modeler/wasteload allocation specialist can examine available Point Source Inventory data in this
                                          5-7

basin.  If the data indicate that the dominant facility, in terms of HAZREL score, is a specific
facility within that basin, this facility and other major dischargers of sediment contaminants could
be further evaluated.  This could include specific modeling to determine if additional or more
stringent permit limits need to be established, or if sediment monitoring should be required.

       The National Contaminated Sediment Management Strategy contains commitments from
over twenty-five  EPA program  offices to  use the National Sediment Inventory,  including
information on  point source releases in activities involving assessment, source control, pollution
prevention and  remediation.  This chapter describes only a few of the possible uses identified in
the National Strategy. It is hoped that through these activities and others, the emerging problem
of contaminated sediments will be better understood and, therefore, more effectively managed
in the future.
