                                 INTRODUCTION
    In recent years, the American public has become increasingly aware of and
concerned about the risks associated with exposure to toxic industrial
chemicals.  This awareness is reflected in the environmental legislation
enacted by Congress and particularly in the Superfund Amendments and
Reauthorization Act (SARA) Title III, also known as the Emergency Planning and
Community Right-To-Know Act (EPCRA).  Under Section 313 of Title III,
businesses must submit annual reports for each toxic chemical manufactured,
imported, processed, or used at the facility, as prescribed in the reporting
rule.*

    Under this reporting rule, facilities must account for the total aggregate
releases to the environment for the calendar year of each toxic chemical
listed under Section 313.  Releases to the environment include:

    •  Releases to air.
    •  Discharges to surface waters.
    •  Releases to land and underground injection wells.

    Many people will want to know the potential health and environmental
significance of the chemical releases reported under Section 313.  Citizens
will also want to know what is being done to control these releases at the
local, State, and Federal level.  They may demand to know why any chemical
deemed 'toxic* is being released at all.  As a health or environmental
official, you probably are already well-versed in evaluating risk and/or in
helping members of the public understand and deal with toxic- chemicals.
However, the Section 313 release data present new challenges for all of us.
The purpose of this guide is to describe some of these challenges and to
suggest ways of approaching them.
*Final rule published in the Federal Register, Feb. 16, 1988,  Vol.  53,
p. 4500.  This risk screening guide should not be used in lieu of Federal
Register documents or the Code of Federal Registry for purposes of compliance.
                                      -i-

-------
A New Age.in Reporting

    Many industries now report release data to the U.S. Environmental
Protection Agency (EPA) and the States under the Clean Air Act, the Clean
Water Act, the Resource Conservation and Recovery Act, and other statutes.
However, under Section 313, a facility must report releases of a chemical to
all media (land, air, and water).  Additionally, the Section 313 reporting
represents a major step forward in collecting data on air releases.  The Clean
Air Act requires reporting on criteria pollutants* only; prior to Section 313
reporting, most air releases were not reported anywhere.

    Section 313 reporting can be viewed as a new beginning in environmental
awareness for both the government and the public.  The reporting represents
the first systematic way of gathering information about the release of toxic
chemicals in or near communities and of making these data readily available to
the public.  Because the reporting is new for everyone - localities, States,
the Federal government, manufacturers, processors, users, and the public -
there will be some initial difficulties in understanding and using the data.

    During the first years of reporting, the release data are expected to be
limited in type and quality.  Not everyone who is obligated to report will do
so.  The data will be summary data, reported in units of pounds per year.  No
information on frequency, duration, or peak release is required, and therefore
this information will not be reported.  Further, the data will often be
estimates rather than measurements of releases, and may be inaccurate due to
misunderstandings or errors in calculation.  Some of the estimates may be off
by as much as an order of magnitude or more.

    Nevertheless, health and environmental officials like yourself will have
access to an unprecedented amount of information concerning the release of
toxic chemicals into the environment.  The Section 313 data will be an
important supplement to existing programs, and they should greatly assist in
* See Glossary for a definition of this term.
                                     -ii-

-------
giving you a broad picture on release of  toxic  chemicals  into  the  environment
since releases to all media  (air, water,  land)  will  be reported under  a single
Act for the first time.
A Two-Fold Purpose

    The information  reported under Section  313  is  likely to spur  many
questions about its  use and interpretation  -  both  within your  organization  and
from concerned citizens.  This guide suggests steps  you  can take  to answer  two
key issues of concern:

    •  How can you respond effectively  to health and ecological  inquiries from
       the public?
    •  How can the releases of greatest potential  concern from a  public  health
       or environmental standpoint be identified from the thousands of forms
       submitted so  that these critical cases can  be further investigated?

    Concerning the first issue, this manual offers guidance in responding to
risk-related questions that the public  will likely ask when the data are made
available (e.g., How dangerous for my health  are these specific releases?).
General strategies for handling inquiries,  tracking  phone calls,  assembling
resources, and disseminating information are  presented.

    To address the second issue, the guide  describes an  approach  for using
Section 313 data as  a supplement to your organization's  current programs to
set priorities for follow-up data collection.   While you want  to  be responsive
to every site that poses a potential problem  and every question from a
concerned citizen, it would be impossible to  treat them  all equally.
Therefore, this guide presents an approach  to prioritizing those  chemicals  or
sites that appear to pose the most immediate  or serious  concerns.
A Map to the Manual

    The guide is divided into five sections:
                                     -iii-

-------
    Section  I presents general  background  information on Title  III  or  EPCRA,
and a specific discussion of Section  313,  including  type,  quality,  and
availability of the  release data  that will  be  reported.

    Section  II defines risk-related concepts and  terms relevant  to  Title  III
and Section  313, including risk screening  - the subject  of this  guide.

    Section  III presents strategies for answering  risk-related questions
from the public.  This section  suggests what you  can  do  to prepare  for
response, how to handle calls as  they come, and how  to set up a  system for
efficiently  responding to queries.

    Section  IV presents a risk  screening system for  use  in your
organization.  This system can help you evaluate potential risks and identify
sites that may pose the greatest  problems.  This  section discusses  why this
approach is  suggested, what its essential elements are,  and how  to  use it.


    The appendices to this guide  compose a  directory  of  resources that should

be of value  to you in using and interpreting Section  313 data, and  in

communicating with the public about them.   These appendices are  referenced

frequently in the guide and consist of the  following:


    •  Appendix A - Contacts.   A designated contact for each EPA Region and
       State is listed.

    •  Appendix B - Toxic Chemical Release  Inventory  Form.  This is the
       reporting form industries will submit to EPA and the States.  A blank
       reporting form and instructions for  completing  it are included  here, as
       well as  a description  of information reported  on the form relevant to
       risk screening.

    •  Appendix C - Release Guidance.   Estimations of  likely rates of
       release  and  release patterns (based on generic  industry data) for
       certain  chemical uses  are provided in this guidance.

    •  Appendix D - Hazardous  Substance Fact Sheet.  The New Jersey
       Department of Health has developed fact sheets on many Section  313
       chemicals.   A sample fact sheet and summary description are provided
       here.   Fact  sheets are  available from the Region and State Section 313
       contacts listed in Appendix A.

    •   Appendix E - Federal  Laws.   Brief summaries of several Federal  laws
       are  provided  in this appendix.

    •   Appendix F - Reportable  Quantities (RQs) and Data for Section 313
       Chemicals  that Are CERCLA Hazardous.  RQs that are available for
       Section  313  chemicals and chemical categories are listed here.
       Included  are  RQs for aquatic toxicity,  acute mammalian toxicity,
       chronic  toxicity,  and potential carcinogenicity.

-------
    •  Appendix G - Systems and Models for Risk Assessments on Environmental
       Pollutants.  The risk assessment models provided here can be used as a
       guide to the kind of information you'll want to collect at a site to
       perform a risk assessment.  The data input elements required for each
       method are listed.

    •  Appendix H - Acronyms and Glossary.  Key terms and acronyms used in
       this guide are defined.

    •  Appendix I - Technical and Risk Communications Bibliographies.  This
       appendix lists many important resources for additional information on
       risk assessment, risk communication, and risk management.


    Attachment A is the hard copy version of •Roadmaps," a Section 313

chemical information directory.  A Roadmaps software package has also been

developed.  Roadmaps can point you to a number of data bases and documents

containing information on health and ecological effects of Section 313

chemicals.  It also contains information on Federal and State regulatory

levels for these chemicals, as well as State contacts for various media

(e.g., air, water) programs.

                            SECTION I - BACKGROUND
What Is The Emergency Planning and Community Right-To-Know Act (Title III)?

    The Emergency Planning and Community Right-To-Know Act (EPCRA) of the
Superfund Amendments and Reauthorization Act (SARA) became law in 1986.
Commonly known as "Title III," EPCRA establishes requirements for:

    •  Federal, State, and local governments and industry regarding emergency
       planning.
    •  Community right-to-know reporting on hazardous and toxic chemicals.

    There are four major parts to EPCRA:  emergency response planning
(Sections 301 to 303); emergency notification (Section 304); on-site
inventories (Sections 311, 312); and toxic chemical release reporting
(Section 313).  Only the toxic chemical release reporting section, the focus
of this guide, is described below.  Information on other parts of EPCRA are
contained in the "Title III Pact Sheet - Emergency Planning and Community
Right-to-Know," available through your EPA Region or State Section 313 contact
(Appendix A).
What Is Meant by Release?

    A release is any spilling, leaking, pumping, pouring, emitting,  emptying,
discharging, injecting, escaping, leaching, dumping, or disposing into the
environment (including the abandonment or discarding of barrels,  containers,
and other closed receptacles) of any toxic chemical.

    For the purpose of this guidance, two types of releases need  to  be defined:

    •  "Burst" releases are typically accidental, rapid releases  of  short
       duration.
    •  Routine releases are those occurring during the conduct of normal
       operation at the facility, and are typically longer in duration than
       "bursts."
                                      1-1

-------
    The guidance presented in this guide is applicable to releases that are
longer in term than bursts, and for which there are limited release data.  A
separate guide, the Technical Guide for Hazard Analysis*, has been prepared
for burst releases of the extremely hazardous substances (EHSs) listed under
Section 302 of Title III.  Burst releases of EHSs should be addressed using
the Technical Guide for Hazard Analysis.  Routine releases should be addressed
using this risk screening guide.

    Under Section 313, the releases reported by facilities will include both
routine and burst releases.  A reported release may have occurred over the
course of a year, or on a single day.  It may be a combination of burst and
routine releases.  Because facilities are not required to indicate the
frequency, duration, or peak release rate of the release, it will be
impossible to know from the reporting form alone whether a release was
accidental or routine, short- or long-term, or both.  For Section 313
chemicals that are also Title III, Section 304 (emergency notification)
chemicals, you could cross-check a Section 313 release with Section 304
reporting (emergency notification) to determine if any part of the release was
accidental.
What Information Will Be Reported?

    Under Section 313, certain manufacturers (Exhibit 1) are required to
submit reports each year on the amounts of toxic chemicals their facilities
store, use, and release into the environment, including publicly owned
treatment works, landfills, and off-site disposal.  The reports must be sent
to both the EPA and the State's designated agency.  A sample Toxic Chemical
Release Inventory Reporting Form (Form R) is provided in Appendix B.  The
first annual report (for the calendar year 1987) was due to EPA and the
designated State agencies on July 1,  1988.

    Section 313 requires reporting of the following chemical releases:

    •  To the air from fugitive or nonpoint sources.  (Fugitive releases are
       those that are not released through stacks, vents, or any other
       confined air stream.)
    •  To the air from stack or point sources.
    •  To the water directly discharged to a receiving stream.
    •  In wastes that are injected underground.
    •  To land on site (including landfills, surface impoundments, or
       landspreading).
    •  To water discharged to a publicly owned treatment works (POTW).
    •  In other wastes transferred offsite for treatment or disposal.

    The quantities reported reflect the amounts of chemical released after any
onsite treatment and are specific to the chemical or chemical category subject
to reporting.  Releases of the chemical to the environment are given in pounds
per year.  The release quantities represent the total amount of the chemical
released from all possible sources for each medium.  For example,  for water
sources, releases estimated separately from process outfalls, pollution
control devices, and washing from containers are added and entered under
•Discharges to Water."  Some sources of chemical wastes are listed in
Exhibit 2.

    Under Section 313, over 300 toxic chemicals and chemical categories are
subject to reporting (a listing of these chemicals is provided in  "Roadmaps,"
Attachment A).  Section 313 also requires reporting of listed chemicals and/or
chemical categories that are components of mixtures.  The company  may use the
name of the mixture or the trade name product instead of the chemical's actual
name only if the specific identity of the chemicals in the mixture are not
known.

    Companies can claim a chemical's identity as a trade secret,  but they must
substantiate such a claim.  A $25,000 fine for frivolous trade secret claims
has been established under Title III.  if a firm claims a chemical is a trade
secret, it must provide a generic name for that chemical, and that name must
be descriptive of the chemical structure.  Companies may withhold  only the
specific chemical identity of the compound - including chemical name and
Chemical Abstract Services (CAS) number.

                        EXHIBIT 2.  SOURCES OP WASTES*
    When estimating releases of a chemical, industries must consider all
sources of wastes.  Sources of waste include, but are not limited to;

Fugitive or non-point air sources

    •  Equipment leaks from pumps, valves and/or flanges
    •  Building ventilation systems
    •  Evaporative losses from surface impoundments

Stack or point air sources

    •  Vents from reactors and other process vessels
    •  Storage tank vents
    •  Stacks or vents from pollution control equipment

Water sources

    •  Process outfalls

-------
What Is the Quality of Section 313 Data?

    Much of the data provided by industries will be based on engineering
estimates, not on actual measurements of release.  If monitoring data are
readily available, industries must use that data to calculate releases.
However, no additional monitoring or measurements are required.  Furthermore,
no information on rates of release (such as duration, frequency of release, or
peak release) is currently required.  This missing information will
significantly decrease the level of certainty in most risk assessments.  In
addition, omissions, misunderstandings, and inaccuracies may occur in
reporting - especially in the first years.  Some smaller companies may not
even be aware they are required to report under this new law.

    KEY POINT:  During the first years of reporting, Section 313 data when
    taken alone are expected to be of limited quality and type for assessing
    risk because of the lack of information on rates of release and
    uncertainties associated with release estimates.

    EPA expects the quality of data to improve in subsequent years as
industries become familiar with the reporting form and the reporting
requirements.  In addition, it is hoped that in subsequent years, the quality
of the data reported will further improve through a program of outreach,
technical audits, facility inspections, and enforcement.  EPA plans to modify
the reporting requirements in the future to obtain additional release
information.  Also, EPA plans to check the reports for obvious errors, and get
them corrected promptly.

    In the interim, it may be possible to estimate likely rates of release and
release patterns based on generic industry data.  Appendix C provides some
guidance on this type of information.  Additional information on estimation
techniques is provided in EPA's Estimating Releases and Waste Treatment
Efficiencies for the Toxic Chemical Release Form.*

-------
How Can the Data Be Used?


    Two immediate uses of the Section 313 data are:  1) responding to health

and ecological inquiries from the public; and 2) identifying and prioritizing

problem releases.  These uses are addressed in this guide.  The Section 313

data may also be used to:


    •  Determine what chemicals to monitor and where to monitor.  In some
       situations, the release data may be used to tell what chemicals should
       be monitored in the environment and, perhaps, where a monitoring
       station should be located.

    •  Help develop control strategies.  The data may be useful in helping to
       develop general multimedia toxic control strategies and assessments, as
       well as strategies to control "hot spots.'

    •  Verify permit information.  The information provided on the release
       form can be cross-checked with permit applications, and discrepancies
       investigated.

    •  Enforce compliance with the law,  onpermitted facilities, illegal
       releases, and unauthorized disposal activities may be identified
       through Section 313 reporting.  Enforcement activities within a
       geographic area or for specific industries may also be targeted.

    •  Reduce waste at the source.  Facilities that need to employ available
       source reduction technologies can be identified, and priorities for
       developing new technologies can be set.


    These applications of the Section 313 data are beyond the scope of this

guide; however, the risk screening system described in Section IV for

prioritizing releases may be useful as an initial step in these other
applications.
How Will the Release Data Be Made Available?


    EPA is mandated to establish and maintain a national toxic chemical

release inventory (TRI) of Section 313 data.  The EPA is required to make this

inventory accessible by computer telecommunications and other means to any

person on a cost-reimbursable basis.  To meet this mandate:


    •  EPA will create the inventory by entering the submitted data into an
       EPA computer.  States and local agencies will be able to access this
       computer directly.

                                     1-7

-------
    •  The inventory will be made available to the general public on the
       National Library of Medicine's (NLM) TOXNET System in the spring of
       1989.  The public data base will be easy to use, and will have
       complementary toxicological and health and safety data files available
       with it.

    •  "Other means" of accessing TRI data are planned for 1989.  Some
       alternatives under consideration are microfiche and compact disk
       (cd-rora).


    States and localities will have the option of accessing the internal EPA

computer rather than the NLM computer.  The internal data base will use BPA's

standard data base management system, ADABAS, and the NATURAL programming

language.  Consequently, it will not be as "user-friendly" as the NLM
computer.  Specific information about accessing both these computers will be
made available as the time of their availability approaches.

-------
                    SECTION II - ELEMENTS OP RISK SCREENING
    Each year, EPA and the States will receive thousands of  Toxic  Chemical
Release Inventory Reporting Forms.  Pew organizations  will have  the  resources
to treat the reported releases equally.  To make decisions about how best to
apply their limited resources, organizations  responsible for handling Section
313 data must develop some system, however crude, for  screening  and
prioritizing the information.  There  is at least one criterion r- potential
risk to public health or the environment - that most organizations may wish to
include as a screening criterion.

    Section IV of this manual describes one approach to evaluating risk  - risk
screening.  This section of the manual introduces this concept and compares it
to two related processes:  risk assessment and risk analysis.  Additional risk
concepts and key terms are also described to  provide background  for
understanding the information presented in the following sections  of this
manual.
What Is Risk Screening?

    Risk screening, in the context of  Section  313 of  SARA,  is  a type  of  risk
assessment used when data are limited.  The process results  in a qualitative
expression of risk  (e.g., high, medium, low).  Risk screening  is useful  for
establishing risk-based priorities and information needs  for follow-up
chemical- or site-specific risk assessment activities.  Although the  risk
screening process relies on general risk assessment principles,  the data input
requirements are less demanding than those for risk assessment.
    KEY POINT:  Risk screening results  in  less  definitive  expressions  of
    risk (i.e., relative  risk rankings)  than  those  derived from the risk
    assessment process  (i.e., estimates  of actual risk).
                                      2-1

-------
 What Are the Differences Between Risk Screening,  Risk Assessment, and Risk
 Analysis?

     Risk assessment is the process of estimating the probability of occurrence
 of adverse  health  or ecological  effects.   A chemical- or site-specific risk
 assessment  has  two major components:*  (1)  the estimation of the probability
 of exposure(s)  resulting from  reported releases,  and (2) the estimation of the
 probability that adverse effects will result from the exposure(s).

     Risk analysis,  in  the context of  Section 302  of  SARA, is the third of a
 three-step  hazards  analysis  process for emergency planning.**  Risk analysis
 requires an estimation of both the likelihood of  occurrence of an accidental
 chemical release (unique to  this process)  as well as the subsequent potential
 for  exposure  (with  emphasis  on human  exposure to  extremely hazardous
 substances).  In risk  analysis,  the major  focus  of the estimation of the
 "consequences*  of exposure (i.e.,  the component  analagous to step (2)  under
 risk  assessment above)  is on the characterization of the potential  magnitude
 of specific adverse  effects, i.e.,  death or  irreversible toxicity,  in  the
 community bordering  sites where  accidental  release(s)  could occur.

     Like risk screening  under Section 313,  risk analysis is a flexible,
 judgmental  exercise  that  results in qualitative  risk statements.  In addition,
 the  responsibility for appropriately  weighting each  of the components  under
 both  risk analysis and  risk  screening is left  to  the affected community  and
 its elected, appointed,  or volunteer  officials.
*Risk assessment in the Federal government is divided  into  four  major  steps:
hazard identification, dose-response assessment, exposure assessment,  and  risk
assessment.  For purposes of this guidance, hazard  identification  and
dose-response assessment have been combined.

provided in the Bibliography.

-------
What  Is  the  Difference  Between Qualitative  and Quantitative Expressions
of Risk?

    Risk may be  described  qualitatively  or  quantitatively.   Qualitative risk
evaluations  may  be based on  limited  data and/or data  estimates,  and therefore
lack  precision.  However,  qualitative  expressions  of  risk are often the best
way to develop an understanding of the interrelationships among  factors
important to the assessment  of risk.   The qualitative approach describes risks
in relation  to other risks,  i.e., in terms  of  relative probability  of  harm.
Descriptive  terms (e.g., high,  low,  or trivial) may be used to categorize the
risk.  Comparisons may  also  be  used.   For example, "The release  of  chemical  A
from  facility X  appears to pose a greater concern  to  local  public health than
most  other releases reported in the area."  Qualitative expressions  of  risk
should be accompanied by a characterization of the nature of  uncertainties.

    Quantitative expressions of risk imply  a far greater accuracy and
certainty of knowledge  than  qualitative  expressions.   However,  quantitative
expressions  of risk should be  presented  with caution.   The  results  of  a
quantitative assessment can  be misused if greater precision and/or  accuracy  is
assigned  to  the  result  than  the input  data  warrant.   Quantitative expressions
of risk  can  be presented if  and only if  the data are  of sufficient  quality,
quantity, and type.  Section 313 release data,  when taken alone, should not  be
used  in  risk assessments that  result in  quantitative  expressions of risk.  The
quantitative approach describes risks  in numerical terms.   For example,  "The
presence  of  chemical A  in the  environment at concentration  B  is  expected to
cause one additional case of lung cancer per 100,000  exposed  individuals."   A
characterization of the nature and potential magnitude of uncertainties should
always accompany quantitative  expressions of risk.
Individual Versus Population Risks

    Risks can be estimated for both individuals and populations.   Individual
risks are most often estimated first.  Groups of individuals  (subpopulations)
exposed to similar concentrations of the same chemical(s) are  considered  to
have similar risks.  The risks to subpopulations considered to
                                      2-3

-------
be more susceptible than average (e.g., children, pregnant women,  sick people,
and elderly people) are determined separately.

    The excess incidence of an adverse effect (e.g., cases of respiratory
distress, cancer) in a population can be quantitatively estimated  by
multiplying the probability of effect (the individual or subpopulation risks)
by the number of individuals in that subpopulation.   The total aggregate
population incidence of adverse effects is the  sum of all these products.
Qualitatively, the estimated excess incidence of adverse effects will increase
as the sizes of the exposed population increases.

    The risk-related level of concern for releases of toxic chemicals should
be based on both individual and aggregate population risks.  For example,
situations with very high individual risks may  be of concern even  though the
estimated number of exposed individuals is very low, and the aggregate risk is
therefore low.  Similarly, large populations exposed to relatively low
individual risks may prompt concern because the aggregate impact would be
significant.
The Two Key Elements of Risk

    The risk screening and assessment processes involve characterizing the
toxicological potency of a substance and the potential exposures to target
individuals or populations.  If the toxicological potency and exposures are
known, the risk can be assessed.

    Toxicological potency information describes the toxicity of a chemical.
It is chemical-specific and, therefore, does not depend on exposure data.
Evaluating the toxicological potency of a chemical involves collecting and
evaluating data on:
                                      2-4

-------
    •  The  nature  of  adverse health or  ecological  effects  that  may  be  produced
       by a chemical  (Exhibits  3  and 4  list  the  adverse  health  and  ecological
       effects  identified under Section 313).
    •  The  exposures  at which those effects  occur,  i.e., exposure
       (dose)-response relationships.

Toxicological potency may be expressed  as  the magnitude  of the  adverse  effect
per unit of exposure.
    Exposure is the amount of chemical  that comes  into  contact with  an
individual or population during a given period of  time.   It  depends  on many
site-specific factors (e.g., how and where the chemical was  released; the
transport and fate of the chemical in the environment;  the behavior  of the
potentially exposed population).  Ideally, exposure  is  measured  at the point
of contact between the chemical and the individual or population, either
directly (e.g., personal monitoring) or indirectly (e.g., amounts of chemicals
in body fluids or tissues).  Opportunities to measure the actual exposure are
rare, however.  Generally, exposure must be estimated from information on the
levels of a chemical in the environment.  Measured environmental
concentrations will result in more accurate estimates of exposure than
estimated environmental concentrations  derived from  release  data (e.g.,
Section 313 data) using environmental transport and  fate models.  Obviously,
the further one must extrapolate from data on the amount or  concentration of a
chemical in the environment to the point of potential exposure,  the greater
the uncertainty in the estimate of exposure.
What Are the Differences Between Environmental Concentration, Exposure, and
Dose?

    The concentration of a chemical in the environment is one of two
components of exposure.  The second component is the amount of the
environmental media in contact with the exposed individual per unit of time.
In the absence of data on the behavior patterns of each exposed individual,
standard assumptions are used for this second component of dose.  These
assumptions, called exposure constants, account for the amount of water or
other environmental media (e.g., air, soil, food) a typical person takes in
                                      2-5

-------
EXHIBIT 3.  HUNAN HEALTH EFFECTS OF CONCERN AS IDENTIFIED UNDER SECTION 313
  •  Carcinogenicity.  The property or quality of being able to cause tumor
     formation in any tissue.

  •  Heritable gene and chromosome mutations.  Events that occur in germ
     cells.  These include deficiencies, duplications, insertions,
     inversions, and translocations of chromosomes, as well as gains or
     losses of whole chromosomes.

  •  Neurotoxicity.  Any adverse effect on the structure or function of the
     central and/or peripheral nervous system related to exposure to a
     chemical substance.

  •  Reproductive and developmental toxic effects (teratogenicity).
     Reproductive toxic effects are adverse effects on male or female
     reproductive ability, while developmental toxic effects are any adverse
     effects on the developing organism, including death,  structural
     abnormalities, altered growth, and functional deficits such as learning
     disorders.  Developmental toxicity also includes teratogenic effects,
     which are permanent structural defects that may adversely affect
     development or survival of the developing organism.

  •  Other chronic effects.  Any adverse effects other than cancer  that are
     observed from long-term repeated exposure to a chemical.

  •  Adverse acute effects.  Adverse effects are any deleterious effects
     suffered by an organism, while acute effects occur rapidly as  a result
     of short-term exposure to a high concentration of a chemical.   For TRI
     listing, both lethal and nonlethal effects (such as eye and respiratory
     irritation) may be considered significant adverse acute effects.   These
     effects occur outside the facility as a result of continuous or
     frequently recurring releases.
                                   2-6

-------
EXHIBIT 4.  ECOLOGICAL EFFECTS OF CONCERN AS IDENTIFIED UNDER SECTION 313
 •  Environmental toxicity.  EPA has identified several indicators of
    toxicity.  These include aquatic LC5Q, mammalian or avian LD$Q, and
    avian 5-day dietary LCso for acute effects.  Chronic maximum
    acceptable toxicant concentrations (MATCs) can be considered for
    aquatic organisms (or cases where some dietary concentration is
    involved).  For avian and mammalian toxicity tests, dosing by gavage is
    frequently employed, and the NOEL (No-Observed-Effect Level) is used.

 •  Toxicity and persistence.  EPA is especially concerned about chemical
    persistence in cases where toxicity concerns are based on chronic
    toxicity data.

 •  Toxicity and bioaccumulation.  Bioaccumulation can be considered by
    evaluating measured bioconcentration factors (BCFs).  in the absence of
    BCF data, the octanol-water partition coefficient (log P) may be used
    to estimate a BCF figure.  Estimated log P data may be used in the
    absence of log P data.

 •  Any significant adverse effect on the environment.  As defined under
    the Toxic Substances Control Act (TSCA) 8(e) policy statement, any
    significant adverse effect means "any ecologically significant change
    in species interrelationships, such as changes in species behavior,
    growth, or survival that in turn adversely affect the behavior, growth
    or survival of other species."
                                   2-7

-------
 per  day.   For  example,  it has been determined that an average adult person
 drinks  about  2 L of water per day.  Therefore, the exposure of an individual
 to a  concentration  of  100 ug/L of  Chemical X in his or her drinking water is
 estimated  to  be about  200 ug/day (100 ug/L x 2 L/day).

     Dose is the amount  of a  chemical  that is absorbed by the body.  In the
 above example,  if 10%  of  Chemical  X were known or assumed to be absorbed, the
 estimated  dose  would be about 20 ug/day.
What  Is  the Difference  Between  Release and Exposure?

    KEY  POINT:  The  release of  a  toxic substance does not automatically
    result in exposure.

    For  exposure  to  occur, the  substance  must  first travel from the facility
to people, animals,  or  other organisms of concern.   Many factors influence
whether  a chemical reaches a target organism and in what concentration.
Chemicals may, for instance, rapidly  break down  once they are released.  They
may be diluted if they  are discharged into air or water.  They may bind to
soils and may not be easily released.   These factors must be  evaluated before
exposure can be estimated from  release data.
Why Must Both Exposure and Toxicological  Potency  Be Known  to Estimate  Risk?

    KEY POINT:  Exposure to a toxic substance  does  not  automatically result
    in toxicity.
    Risk is a measure (qualitative or quantitative) of  how close measured or
estimated exposures are to those known to cause toxic effects.   Obviously,  the
lower the exposure, the less the risk.  Exposures to organisms  of concern may
be below levels required to cause toxic effects or  below unacceptable  risk
levels.  After potential risks or relative  risks  are assessed,  a determination
must be made as to the "acceptability" of the  risk.  Although not the  subject
of this manual, a few references on this  subject  have been included  in the
Technical Bibliography.

-------
                     SECTION III  - RESPONDING TO QUESTIONS
    Responding to people's questions and concerns about the Section 313
chemical releases will not be an easy task.  Communicating information on life
and health issues is never simple, for these subjects evoke strong emotions.
Your job is made more difficult because the data, at least in the first years
of reporting, will be limited.  In addition, while data may be available for
each listed chemical, little or no data will be available on the impact of
exposure to more than one release or to chemical mixtures.  This section of
the guide provides general strategies for preparation, information gathering
and dissemination, and response.  General references for risk communication
are listed in Appendix I.
What Can You Do to Prepare for Response?

    There are several steps you can take and resources you can assemble to
prepare yourself for responding to Section 313 questions.  Exhibit 5 is an
"Action Checklist" designed to help you prepare for responding to questions.
This checklist consists of three parts:  1) answering questions, 2) assembling
information; and 3) disseminating information.  The checklist was designed to
help you test your agency's preparedness, and to identify ways to make your
response efforts as efficient as possible.

    The designated Section 313 State agencies will have different methods for
handling queries.  Some may opt to centralize all queries.  Others may refer
calls to various State media offices, State or local health departments, etc.
Since most questions are likely to be local in scope, a system for referring
these calls to the appropriate local agencies and/or officials would be
valuable.  The "Action Checklist" suggests some strategies for handling calls
as they come in, such as establishing an intra-State/Regional or local network,

    The strategy should include a system for recording information regarding
calls.  You might create a special form for this purpose.  The information
could also be computerized.  In either case, you'll want to record basic
                                      3-1

ANSWERING QUESTIONS

1.  How will you handle the calls  as they  come  in?  Will you:

    •  Designate one or more people  to answer the questions?

    •  Prepare a guide instructing secretaries  and  others who  generally  answer
       the phones on how and where to forward Section 313 related  calls.

    •  Establish an intra-State/Regional or local network to handle  questions
       you will he getting?

    •  Supply written responses  to Inquiries?   If so,  what will you  provide?

    •  Suggest callers follow up inquiries  with a letter detailing their
       concerns?

2.  If you intend to designate people to answer questions, do  you  know who
    within the Region, State, or locality are the contact points for answering
    specific questions related to:

    •  Health and/or environmental effects?

    •  Exposure and risk assessment?

    •  Air, solid waste, ambient water, and  drinking water questions?

    •  Standards and regulations?

3.  How will you document calls as they come in?  Will you:

    •  Create a form that responders can use to record essential information
       on each call?

    •  Create a system that enables you to  track how many calls were received
       per facility?

    •  Periodically review these files to ascertain the level  and  nature of
       public concern?

4.  If a serious problem is apparent:

    •  Do you know what action your agency can  or will take?

    •  Can you communicate this to the public?
                                  3-2

    the questions?

    •  Are copies of the Toxic Chemical Release Inventory Reporting  Form
       readily accessible?  A sample Form is provided in Appendix B.

    •  Will you have access to the TRI data base (when it becomes available)
       or the data on the data base?

    •  Can you access the EPA "Roadmaps" data base that has been developed?
       Attachment A is a hard copy version of "Roadmaps."

    •  Do you have information related to the health and/or environmental
       effects of the TRI chemicals, e.g., EPA Hazardous Substance Fact Sheets
       (Appendix D); Agency for Toxic Substances Disease Registery (ATSDR)
       Toxicological Profiles*; printouts from EPA's Integrated Risk
       Information System (IRIS), and Chemical Emergency Preparedness Program
       (CEPP) Profiles?**

    •  Do you have a listing of certified toxicologists in the area  who are
       willing to assist in responding to citizens' health questions?

    •  Do you know the status of Federal regulations on the Section  313
       chemicals?  See Appendix E for brief descriptions of several  Federal
       laws.

    •  Do you know how your state regulates the Section 313 chemicals?
*Under SARA, Section 110, ATSDR and EPA are required to develop toxicological
profiles on a specified number of hazardous substances commonly found at
facilities on the Superfund National Priorities List (NPL) and which pose the
most significant potential threat to human health.  Some of these profiles
have been completed on Section 313 chemicals and are available through ATSDR.

**IRIS is an on-line data base that contains the latest information about EPA
health assessments and regulatory decisions on over 260 chemicals.  It has
been designed especially for Federal, State, and local environmental health
agencies.  CEPP Profiles contain information for chemicals on the EPA list of
Extremely Hazardous Substances, such as acute hazard information, chemical
properties, and emergency handling techniques.  Descriptions of IRIS and CEPP
Profiles are provided in the hard copy version of "Roadmaps" (Attachment A).

-------
                     EXHIBIT 5 - ACTION CHECKLIST (con't)
    •  Do you have access to data from State media programs (e.g.,  air toxics
       or water releases)?  These programs can provide information  on
       regulation and compliance.  They may also have monitoring data and/or
       environmental fate and transport information on specific chemicals.
       State programs may also be able to tell you if a chemical has a state
       air or water standard, and if a particular release is permitted,   in
       this way, toxic chemicals released into the environment without permit
       restrictions or standards can be identified.  State programs may also
       be aware of a permitted company's compliance record.  Contacts for
       State media programs are provided in "Roadmaps" (Attachment  A).

    •  Have you collected maps containing site-specific information, such as
       facility locations, meteorological, topological, hydrological, and
       demographic information (including sensitive population locations) in
       your geographic area that are important to exposure evaluations?

    •  Have you contacted local groups or associations, e.g., libraries,
       weather services,  Local Emergency Planning Committees (LEPCs), in your
       geographic area of responsibility to determine their willingness  to
       provide site-specific information?

    •  If you answered no to any of the above questions,  do you know where  to
       get the information?

2.  Will you read local newspaper articles to prepare responses to  anticipated
    questions?

3.  Do you want to prepare summary data of the Toxic Chemical Release
    Inventory Reporting Forms?  If so, will you do it by:   	state  	county
    	zip code 	industry?
DISSEMINATING INFORMATION

1.  Have you made plans to distribute the Toxic Chemical Release  Inventory
    Reporting Forms to the public?  Will you distribute summary data  of  these
    Forms?

2.  Do you have plans to publicize your phone number?

3.  Do you have summary information that you can give to the public concerning:

    •  The community right-to-know program?  (Title III Fact Sheets and
       Right-to-Know Brochures  are available from the State and EPA Regional
       Section 313 contacts listed in Appendix A.)

information about.the caller and the request as well as your responses or
action:

    Call Log-in
    •  Caller's name (check your organization's policy regarding your abiltiy
       to keep callers' requests and queries confidential).
    •  Address.
    •  Telephone number.
    •  Date and time of call.
    Nature of Call
    •  Facility(s) of concern.
    •  Chemical(s) of concern.
    •  Caller's specific concerns.
    •  Reasons for concern.
    •  Source of the caller's information.
    •  Other information about caller's problem.
    Response
    •  Nature of verbal response provided.
    •  Documents sent.
    •  Other follow-up actions taken.
    •  Suggestions for  further follow-up/response.

The checklist also suggests that you periodically review the call information
to monitor the level and nature of  public concern.  This will be useful in
identifying releases, facilities, and communities that may require follow-up
activities (see Follow-up Activities later in this section).

    Assembling information that can help you answer questions is another
important part of preparation.  The 'Action Checklist" lists key resources,
including documents and data bases.  Finally, the checklist asks you to
consider what information you will  distribute to the public, how you will
                                     3-6

-------
distribute it, and what resources and information could be shared with other
programs and agencies.
What Questions Will Be Asked, and Who Will Ask Them?

    The questions that are likely to be asked of you will come from citizens,
workers, local and national environmental groups, realtors, health
professionals, lawyers, industry, and others.  They will take the form of
phone calls, letters, and questions at public meetings.  A steering committee
of Federal, State, and local government representatives that helped develop
this document identified several questions likely to be asked about the
Section 313 data.  These questions fall into two main categories:  1)  risk
assessment and 2) risk management:
    Risk Assessment Questions

    •  Am I exposed?
    •  To how much of Chemical X am I exposed?
    •  Will I/my child get sick (e.g., die, get cancer)?
    •  Is my present sickness (or that of my child or my community)  the result
       of past exposures to toxic chemicals?
    •  How can I be sure if Chemical X caused this effect(s)?
    •  What if I am exposed to more than one chemical?
    •  Is the decline of the fish population in Lake X a result of these
       releases?
    •  Can I eat the fish from this lake?

    Risk Management Questions
    •  What is being done to control releases?
    •  Is the chemical regulated?  If not, why not?
    •  How can I get more information about these releases?
    •  What can I do to get the release of a particular chemical reduced?

                                      3-7

-------
 How Can These Questions Be Answered?

     The response to each question will vary depending on such factors as:

     •  The quality and type of data available.
     •  The level of knowledge of the questioner.
     •  The time and resources available to answer the question.

     Obviously, if sufficient data have been gathered to estimate exposure, a
 more specific answer can be given than if only data from the Section 313
 reporting form are available.  Depending on what understanding the questioner
 has  of basic risk assessment issues, the response will also vary in terms of
 the  terminology used and the depth of the response.  Finally, you may be able
 to answer a question more thoroughly at a community meeting, for instance,
 where you have an hour to speak than you could in an over-the-phone response.
Sample Question

    Hi.  This is Charlie Citizen from Town of Concern, Indiana.  I live two
    miles from the No Name Company, and I just read in the newspaper that the
    company is dumping 10,000 pounds of Chemical X into the air over the
    course of a year, and the newspaper also says it causes cancer.  I want to
    know if this exposure is going to affect me and my family, and what you're
    going to do about this?

    Charlie Citizen is really asking two questions:  1) Am I at risk? and
2) What is your agency doing to control/stop/regulate the release?  The first
question is asking for an estimate of actual risk - the goal of risk
assessment; the second question is asking that a risk management decision be
made (or communicated, if such a decision has already been made).
Responding to Questions Concerning Actual Risk

    Attempting to answer questions that ask for estimates of actual risk will
be very difficult given the limited type and quality of data that will be
provided on the Toxic Chemical Release Inventory Reporting Form (Form R).  You
                                     3-8

-------
could take the following three-step approach:

    1. Determine what information is needed to answer the question.
    2. Determine what information is readily available.
    3. Decide what you can tell the questioner.


    Step One;  Determine What Information Is Needed to Answer the Question

    To determine actual risk, you need to perform a risk assessment.   To do a
risk assessment, you need to know the toxicological potency of Chemical X.
This means you need to collect and evaluate data on the adverse health or
ecological effects that may be produced by Chemical X and the doses at which
those effects occur.

    You also need to know the exposure, or amount of chemical with which
Charlie Citizen is in contact.  To determine this, you need to collect and
assess site-specific information - ideally personal monitoring or measurement
of the amount of Chemical X in Charlie Citizen's body fluids or tissues.
Alternatively, if concentrations of Chemical X in the environment are known,
you could estimate exposure by using exposure models (appended to some
environmental transport and fate models, e.g., GEMS, see Appendix G).  If only
release data are available, environmental concentrations and exposure must be
estimated (see Appendix G).  Quantitative estimates of exposure from Section
313 emissions data, without information on rates of release and a clear
understanding of the quality of the data, will seldom be of sufficient
certainty to be meaningful.  At a minimum, contact with the chemical company
will be necessary to obtain this type of information.


    Step Two:  Determine What Information Is Readily Available

    Information on the toxicological potency of Chemical X is likely to be
available for many section 313 chemicals.  Roadmaps (Attachment A) identifies
several sources of potency information,  if you have taken the preparatory
                                     3-9

-------
steps outlined in the Action  Checklist  (Exhibit 5),  you will have additional
resources oh hand such as  the EPA  Hazardous  Substances Fact Sheets, ATSDR
Profiles, and the "Roadmaps"  data  base  which can point you to documents and
data bases with health and/or ecological  effects information.  The reporting
company may also be an important source of information.

    As for determining exposure, you  know from Charlie Citizen that the amount
of Chemical X being released  to the air is 10,000 pounds annually.  You can
verify this information by consulting the Toxic Chemical Release Inventory
Reporting Form submitted by the company for  this release.  Charlie Citizen has
also told you that the exposure point is  two miles from the facility.   What
you don't know is Charlie  Citizen's actual exposure  to Chemical X, or  the
duration of this exposure.  To make these determinations, you will need to
collect site-specific data.   Some  questions  you might  ask the Technical
Contact designated on the  Toxic Chemical  Release Inventory Reporting form are
listed in Exhibit 6.  More information  on the type of  data you'll want to
collect for risk screening and risk assessment is presented in Section IV.
    Step Three;  Decide What You Can Tell the Questioner

    You should tell Charlie Citizen that you can't  answer  his  question with
the information you have.  You may need to explain  what risk assessment is,
why you need to do this process to answer his question, and why you  don't  feel
comfortable doing risk assessment with just the Section 313 data.  You  may  also
want to explain to Charlie Citizen that there are good  reasons to  question the
accuracy of the reported data and what you are doing  (if anything) to  get
better data.

    Charlie Citizen can also participate in answering his  own  question or  in
taking action to reduce the perceived risks.  Citizens' participation  is
important and should be encouraged.  You can tell callers  how  they can help
collect information to answer their own questions,  especially  if these
questions relate to potential exposure.  This can be  done  by referring callers
to potential sources of information and carefully explaining what  they might
realistically attempt to do (Exhibit 7).  Citizens  should  be encouraged
                                     3-10

-------
          EXHIBIT 6 - QUESTIONS TO ASK  A COMPANY'S TECHNICAL CONTACT


 1.  Does the total quantity of the  release  reported  include any accidental
     releases?  If so:

     •  When did they happen?

     •  How much of Chemical X was released?

     •  How likely is it for such a  release  to  happen  again?

 2.  What is the frequency of any routine  release(s)?

 3.  What is the duration of any routine  release(s)?

 4.  When and what is the peak release?

 5.  How long have there been releases of  Chemical  X?

 6.  Do reported releases reflect past  release  levels?

 7.  Is the release pattern of Chemical X  expected  to  change in  the  future?

 8.  If the Toxic Chemical Release Inventory Reporting Form  lists  a  mixture or
     chemical compound,  what substances might be expected to be  present  in  the
     mixture or compound, and in what quantities?

 9.  Is the company employing best practicable  technology (BPT)  or best
     available technology (BAT)?  What are they?

10.  Has the company done any monitoring?  If so, is this information
     available?  What sampling and analytical methods  were used?

11.  Has the company attempted to model potential exposures  from release or
     monitoring data?  If so, what models  and assumptions were used?

12.  Is any toxicological information available on  Chemical  X?

13.  Is any information  available on potential  fate and transport  of Chemical
     X?
                                   3-11

-------
                  EXHIBIT 7 - SUGGESTIONS FOR CITIZEN ACTION

    Here are some actions the public might take to voice its concerns (you
might have additional ideas or contacts to which you can point concerned
citizens):

    •  Contact the company.  Most companies are concerned about their public
       image and may be more than happy to establish a meaningful liaison with
       a concerned citizen or citizens' group.  Call or write the public
       contact designated on the Toxic Chemical Release Inventory Reporting
       Form.

    •  Obtain more information.  Potential sources for information include:

       - The chemical company itself.
       - Local libraries (may be able to provide the citizen with a list of
         references).
       - State or local health and environmental protection departments.
       - Medical and public health schools.
       - Hotlines, clearinghouses/ and support centers (such as the TSCA
         Assistance Office at (202) 554-1411 or for the hearing impaired, TDD
         (202) 554-0551).
       - The Environmental Protection Agency (Regional offices).

    •  Write a follow-up letter.  Citizens can write to:

       - The designated Region or Section 313 State contact.
       - Local government officials such as the Mayor, town council members,
         or selectmen.
       - The Environmental Protection Agency (Federal, Regional, and State
         offices).
       - Congressmen.
       - The reporting  company.
       - Local and national environmental groups.

    •  Investigate control technologies.  Citizens can find out what the
       state-of-the-art control technology is for  a particular industry, and
       compare it to what the facility is using.  Citizens can contact their
       EPA Region or State Section 313 contact for information on
       state-of-the-art control technologies.

    •  Contact the family physician to discuss medical concerns.

    •  Identify other concerned citizens.  Citizens may find it fruitful to
       work  together in performing the activities  listed above.  The Local
       Emergency Planning Committee may be a good  starting place for
       networking with  other citizens.
                                     3-12

-------
to work in a spirit of cooperation and communication with the various groups
they come in contact with in achieving their goals.

    Finally, you could offer to send Charlie Citizen additional information
about Title III and the potential health and environmental effects associated
with the chemical(s) reported to be released from the No-Name Company.   Title
III Pact Sheets, Right-to-Known Brochures,  and Chemical Pact Sheets are
available from the State and EPA Regional Section 313 contacts listed in
Appendix A.  To facilitate information dissemination, you might send callers a
"request for more information" form.  A sample form is provided in Exhibit 8.
Your State or locality may wish to modify this form or create your own
materials (if you haven't already) to best suit your needs.   For example,  a
list of the type of materials or information your agency can typically  provide
would be a useful adjunct to the form.
Responding to Risk Management Questions

    Charlie Citizen also wants to know what is being done about regulating or
controlling the release.  You can find out what Federal and State regulations
apply to the chemical through State and Regional contacts, Roadmaps,  and other
sources.

    If the chemical is regulated, say so.   To address why a chemical  is not
regulated, you need to be familiar with State and Federal regulatory  programs
and legal constraints, as well as factors  that are considered in regulatory
control and decision-making.   You might review a chemical's regulatory history
to determine whether regulation was considered in the past.  Emphasize to
Charlie Citizen that this is  the first time any government agency at  any level
- local, State, or Federal -  has had access to these data.  The government is
assessing data to determine the extent of  possible risk and will be taking
action, as appropriate, under existing legislative mandates.

    If a facility is in compliance with laws and standards covering
Chemical X, you should explain how the standards were set.  Explain to Charlie
Citizen the extent to which potential health effects of Chemical X were
                                     3-13

-------
                   EXHIBIT 8 - REQUEST FOR MORE INFORMATION*

considered in setting the standards  -  and  the  extent  to  which the laws require
such considerations.  Finally, let Charlie Citizen  know  that  States  and the
Federal government intend to evaluate  the  Section  313 data  to determine the
adequacy of existing regulations and standards.
Follow-up Activities


    This section has described short-term  response  to  citizens'  queries.

Depending on your organization's resources and priorities,  you may  also wish

to flag certain queries for follow-up.   These queries  can  be identified in

several ways:


    •  Information provided by a caller  may  suggest that a situation  deserves
       further follow-up.

    •  Periodic and systematic review of the call logs will help identify
       releases, facilities, or communities  for which  there have been
       unusually high levels of concern.

    •  The risk screening described  in Section IV will help identify  releases
       and facilities that should receive a  higher  priority for  follow-up from
       a public health and environmental standpoint.


    Long-term follow-up may take several forms:


    •  Public meetings.  These will  enable direct communication  between your
       agency and concerned parties.  Such communication is particularly
       important in communities that have voiced a  high level of concern.

    •  Information gathering.  Any information that  enables you  to  put
       potential exposures into perspective  will be  useful  in responding  to
       citizens' concerns.  For example, if  you receive many calls  about  a
       particular chemical, you could obtain information about ongoing
       exposures to that same chemical that  have not caused harm and  that have
       been accepted by the community or nearby communities (if  such
       information is available).

    •  Follow-up letters.  If you do obtain  more information of  relevance to
       an original call, send it to the  citizen or  citizens who  called.


Your organization should consider the various options  and  determine how and

when to exercise them.

                   SECTION  IV - QUALITITIVE RISK SCREENING:
                      A SYSTEM FOR  PRIORITIZING THE DATA
    This section of the guide suggests a  screening  system  for  using  the
Section 313 data to set priorities  for follow-up activities  and to determine
the additional data that would be most useful  for such  evaluations.   The
system is consistent with EPA's understanding  of the  type  and  expected  quality
of the Section 313 data and readily available  supplementary  data.  Also,  the
system is intended to be flexible,  and each  organization should use  judgment
in applying and interpreting it.
An Overview of the System

    This screening system follows the basic  risk  assessment  steps.   By
considering available information on (1) toxicological potency  in conjunction
with general indicators of  (2) exposure, you  will  gain useful  insights  into
the potential public health and ecological risks  of certain  releases.   These
insights may help you determine whether  releases  should  receive a high,
medium, or low priority for further investigation.
Background on Ranking Relative Toxicological Potency

    For risk assessment, the toxicological potency of a chemical  is  assessed
by assembling original toxicological data or reviews of such  data.   For  risk
screening purposes on Section 313 data, this is unnecessary.  Given  the
uncertainties in the data available for exposure evaluation,  the  relative
toxicological potency of the chemicals (rather than the actual  toxicological
potency) is all that is needed.

    Several systems are available for ranking  relative toxicological potency.
One such system is the Reportable Quantities (RQs) developed  under the
Comprehensive Environmental Response, Compensation and Liability  Act of  1980
(CERCLA).  The RQ for a substance is the level at or above which  a release  of
                                      4-1

-------
that substance must be  reported to the  National  Response Center (NRC),  the
State Emergency Response Commission,  and  the  Local  Emergency Planning
Committee.  There are five levels of  RQs:   1,  10, 100,  1,000,  and 5,000
pounds.  An RQ is assigned to a chemical  based on a consideration of the
chemical's intrinsic chemical, physical,  and  toxicological  properties.   The
lower an RQ, the higher the relative  toxicological  potential of the chemical.
Thus, RQs can be used as crude indicators of  a chemical's overall relative
potential to cause toxicological and/or ecological  effects  at  a given exposure
level.

    In assigning an overall RQ for a  substance,  up  to  six individual RQs are
calculated separately for aquatic toxicity, acute mammalian toxicity, chronic
toxicity, potential carcinogenicity,  reactivity, and ignitability.   Pour of
these are based on health or ecological effects  (aquatic toxicity,  acute
mammalian toxicity, chronic toxicity, and potential carcinogenicity) and are,
therefore, appropriate as a basis for assigning  relative toxicological  potency
to Section 313 chemicals.

    RQs appear to be an appropriate hazard  ranking  system for  Section 313
chemicals for the following reasons:

    •  The RQ score considers type of effects, severity of  effects,  and
       dose-response for the endpoints of concern under Section 313.
    •  The RQ score is based on data  in primary  literature  sources.
    •  Data evaluation under the RQ system  is  consistent with  EPA's  risk
       assessment guidelines.*
    •  RQs have been peer-reviewed and endorsed  by  the  EPA.
    •  RQs have been developed for more than  two-thirds  of  the  Section  313
       chemicals.

    Appendix F lists the aquatic toxicity,  acute mammalian  toxicity,  chronic
toxicity, and potential carcinogenicity RQS.   Toxicity  data  (e.g., acute

inhalation LC  s) assigned to Section 313 chemicals  that  can  be  used  to rank
chemicals according to their potential to cause  these  effects  are  also
presented.  RQs for hazardous substances that are members of  the 20 toxic
chemical categories listed under Section 313 are listed as  well.  Additional
information on assigning RQs is provided in Exhibit  9.
Factors to Consider in Evaluating Exposure Potential


    Potential exposure is evaluated for each medium based on consideration  of

many variables.  For the purposes of qualitative risk  screening,  several
factors can be considered as general indicators of potential exposure:


    •  Quantity of Substance Released - The greater the quantity  released,  the
       greater the potential for exposure.

    •  Transport Mechanisms - The closer the proximity of the  release  to  an
       available transport medium that can convey the  chemical to a
       population, the greater the potential for exposure.  For example,  a
       release directly to air or a waterway offers greater exposure potential
       than a release to a lined impoundment located far from  any sources of
       ground water.  Meteorological, topological, and hydrogeological
       conditions will affect the transport of the chemical, and  therefore
       must be considered.

       - For air exposures, the individuals and populations exposed to  the
         highest concentrations will generally be located downwind and  nearest
         to the source of the release (dependent upon  emission stack height).

       - For ground water, in general, nearby wells will have  higher chemical
         concentrations than distant wells, and wells  in the direction  of
         ground-water flow will have higher chemical concentrations.

       - For surface water, the significant exposure points depend on
         downstream uses of the water.  Downstream use includes drinking,
         cooking, bathing, water contact sports, agricultural  livestock
         watering,  and industrial use.  Discharges of volatile chemicals  to
         water can also become significant sources of  air pollution, and
         affect target populations in this way.

       - For soil,  individuals and populations in nearby areas will be  more
         likely to be exposed than those at a greater  distance.  A toxic
         chemical may also be taken up by plants or grazing animals and
         subsequently be ingested by humans.  Soil may also be a  significant
         exposure pathway for children with a tendency to eat  dirt.  In some
         circumstances, contaminated soil can also become airborne and  be
         carried significant distances.

              EXHIBIT 9 - DSXNG RQS IN THE RISK SCREENING  SYSTEM
     Assigning the appropriate RQ to a Section  313 chemical  will  depend  upon
your understanding of the target populations/organisms of concern and  the
reported chemicals' likely release rates.  Choosing  the  lowest  RQ in  the
examples below will give you conservative results for risk screening.

     •  If you are concerned about health and ecological effects, select the
        lowest RQ value from among the four RQs for  that chemical:  aquatic
        toxicity, acute mammalian toxicity, chronic  toxicity, and potential
        carcinogenicity.

     •  If you are concerned about aquatic effects only, select the aquatic
        toxicity RQ.

     •  If you are concerned about human health effects  only, select  the
        lowest RQ from among the three human health  values.

     •  If you are concerned only about human health effects and  if release
        data indicate a frequent or relatively continuous release that implies
        relatively long-term exposure, use the lower of  the  potential
        carcinogenicity and chronic toxicity RQs.

     Other guidelines apply to mixtures or trade secret  substances  for which
generic names have been given; to chemical categories; and to chemicals  for
which no RQ has been assigned.

     •  Generic names.  If you can ascertain from the generic name  the types
        of chemicals that might be components of the substance, you can  select
        from among the most toxic of these chemicals for risk screening.  If,
        however, you can't make such a determination, consult with  .the
        facility to collect sufficient information to put boundaries on  the
        potential toxicity of the substance.

     •  Chemical categories.  Some chemicals that make up the 20  categories
        listed under Section 313 have RQs.  Select the most  toxic of the
        chemicals listed in the category that exhibits the same properties
        (e.g., physical state) as the compound of concern.   Absent  any
        information on the toxicity of the reported  compound, you should
        generally use the most toxic chemical listed in the  category for
        conservative risk sceeening.

     *  No RQ.  if a chemical does not have an RQ, you can assign a relatively
        toxic RQ (i.e., 10 or 100) to the chemical for the purposes of
        screening.  Again, assuming relatively high  toxicity will result in
        the most conservative screening.
                                       4-4

-------
    •  Chemical Fate - Various characteristics of the  chemical  will  affect its
       duration and where it will finally reside in the  environment.   These
       characteristics include:

       - Stability - The more stable and persistent a  chemical  is  in  the
         environment, the greater the potential for exposure.

       - Mobility - The more mobile a substance, the more  widespread  the
         potential for exposure, but the lower the likely  exposure
         concentrations.

       - Media affinity - Media affinity refers to the tendency of the
         chemical to move from the media into which it was  discharged  to
         another media.  For instance, if a chemical has affinity  for  water
         and is released into water, it is unlikely to move from that  media to
         another.  On the other hand, a volatile chemical  released into water,
         is likely to move into another medium, such as  air.

    •  Population Characteristics - Characteristics of the  target  population
       or environment can influence exposure.  These include:

       - Density.  The more dense the nearby population, the greater  the
         number of people that may be exposed.

       - Sensitive Populations or Sensitive Environments.*  Certain
         populations or environments may be more susceptible than  average  to
         exposure.  Reviewing information on the site  area  can  indicate
         whether sensitive populations or environments are  present.

    •  Individual or Population Behavior - Population  behaviors (e.g., eating
       habits, recreational activities of humans) will affect exposure.  For
       example, if a given pollutant concentrates in fish  tissue,  the  amount
       of fish consumed by the potentially exposed population is a critical
       factor affecting exposure.

    The potential for exposure is estimated, based on  the  available data,  by
filling out a questionnaire provided at the end of this  section.   The
questionnaire is described in more detail below.
Using the Risk Screening System


    The risk screening system presented in this guide consists of  three  parts:
*See Glossary for definitions of these two terms.
                                      4-5

-------
    •  The Risk Screening Procedure.
    •  The Questionnaire for Qualitative Screening.
    •  The Facility Risk Screening Worksheet.

    The risk screening procedure requires  the  user  to  address  the  questions in
the questionnaire in the order prescribed  and  to  record  results  on copies  of
the facility worksheet.  All three items are used concurrently in  performing
the risk screening, and you will work back and forth among  them.   The  three
parts are described in more detail below.

    Sources of information useful for risk screening are listed  in Exhibit 10
at the end of this section.  The more reliable information  you access  in
responding the questions, the greater the  confidence you can have  in  the
results of the screen.
    The Risk Screening Procedure

    The screening procedure provides a logical process  for  considering  the
many variables associated with a determination of potential risks  at a
facility or site.  It describes how to screen potential  risks among multiple
facilities each releasing several chemicals into different  environmental media
(air, water, and land/ground water). The same approach  may  be used to
determine relative risks among chemicals at a specific  facility.

    There are essentially four steps to the procedure:

    •  Perform a preliminary assessment to determine plausible routes of
       exposure and the target organisms of concern.
    •  Assess toxicological potency, using the RQ system described earlier.
    •  Perform exposure ranking.
       - Rank release quantities for each chemical.
       - Consider further the magnitude of potential exposures for each
         plausible route of exposure.
                                      4-6

-------
    •  Rank facilities or geographic areas based on  relative  risk.   Chemicals
       and facilities can be ranked according to potential  risks  to  humans  or
       ecological organisms from releases into each  environmental media.  At
       the risk screening stage, an overall risk ranking for  a specific
       chemical or facility cannot be determined where multiple  routes of
       exposure are likely.
    The Questionnaire for Qualitative Screening

    The questionnaire requires the user to draw qualitative  conclusions  in
response to a series of questions, e.g., to  judge whether  releases  are  "high,
medium, or low,* or whether people are "close to or far  from"  the release
site.  The questionnaire is meant to be flexible enough  to serve the  interest
and needs of a diversity of users in all parts of the country.  Therefore,
quantitative limits on these terms are not provided (with  a  couple  of
exceptions which are presented for illustrative purposes)  since quantitative
perceptions of "high" or "close to" will differ among site locations, areas  of
the country, program emphasis, etc.

    Since answering the questions may involve making estimates, the risk
screening procedure is best performed by two to four individuals who can reach
consensus on what estimates are appropriate.  Also, for  consistency within
your own program, you may want to consider establishing  quantitative  ranges  or
limits for each of the qualitative terms in  the answers  to the questions which
will meet your program objectives and the community interests.
    The Facility Risk Screening Worksheet

    The results of the screening procedure are recorded on copies  of  this
worksheet.  A sample worksheet is provided at the end of  the questionnaire.
You'll want to make several copies of this worksheet since one worksheet must
be filled out for each individual or population of concern for which  there is
a plausible exposure route.
                                      4-7

-------
Other  Factors  to  Consider

    The  risk screening  system presented  in  this guide is based solely on
considerations of  risk  to public health  and the environment.   In your decision
on  the type and extent  of follow-up  activities of a facility or geographic
area,  you may  wish to consider  other non-risk  factors,  e.g.,  permitting,
public concern, control technologies,  economics, and politics.

    Before applying  this risk screening  system, organizations may wish to
determine whether  the release is permitted  and meets the permit requirements.
Releases from permitted facilities in  compliance with the permit(s)  may be
less likely to pose  a concern than an  unpermitted release or  one in  violation
of a permit.  Organizations may also want to be responsive to the level of
public concern about an area, facility,  or  individual release.  Such concern
may be an important  indicator of a situation requiring  some follow up, both
from a public health/environmental and a political standpoint.  If a facility
is already using best practicable technology (BPT) or best available
technology (BAT),  it may not be able to  reduce the level of releases any
further without tradeoffs.  Budgetary  restraints and political factors will
also be important  considerations.
After Prioritization - Then What?

    After narrowing down specific emissions  or  sites  that  appear  to  require
further investigation, the risk assessment models provided in  Appendix  G can
be used as a guide to the kind of information you'll  want  to collect  to
perform risk assessment.  The appendix includes a description  of  data input
elements required in each method.  These input  elements, along with
information on data gaps identified in completing the Questionnaire  for
Qualitative Screening, can help you decide what information needs to  be
collected and/or data generated to determine actual risk.
                                      4-8

-------
                         THE RISK SCREENING PROCEDURE
1.  Preliminary Exposure Route and Target Organism Screen

    •  Run a quick first pass through the "Plausible Routes of Exposure"
       section of the questionnaire to determine plausible routes of exposure
       to humans and ecological organisms.  For example, if there are no
       drinking water intakes and no swimming or fishing in the vicinity  (say,
       10 Km) of a water discharge, then exposure potential to humans via
       surface water is low.  (See note on distance in the questionnaire  on
       page 4-13.)

    •  Drop exposure routes determined to be implausible.  These routes should
       be further evaluated during risk assessment, if determined necessary.

    •  Pill out the "Site, Media, and Organisms of Concern" lines of the
       "Facility Risk Screening Worksheet." (NOTE:  You need to fill out  a
       separate worksheet for each media and each organism of concern.)

2.  Assess Toxicological Potency

    •  Look up and record the lowest RQ values of each chemical released  into
       an environmental media for which there is a worksheet.  See Exhibit 9
       for guidance in assigning RQ values.

    •  Complete the "Toxicological Potency" section in the Questionnaire.

    •  Enter the chemicals assigned "high" and "medium" toxicological
       potencies in the appropriate sections on the facility worksheets under
       "Chemical Name."  (Do not list chemicals assigned "low" toxicological
       potency.)

3.  Determine Exposure Potential

    Release Quantities

    •  Group facilities where emissions are close together (e.g., emission
       stacks or discharge pipes that are within perhaps 1 Km of each
       other)unless there are reasons not to do so (e.g., residences or
       recreational areas in between discharge locations).  See note on
       distance in the questionnaire on page 4-12.

    •  Add releases of chemicals in common among grouped facilities as though
       releases occurred from one site.  Consider combining releases for  any
       chemicals that are known to cause toxic effects by the same or similar
       mechanisms of action, or that have a common site of toxicity, (e.g.,
       liver, lung).  If the toxic effects of a chemical are not known, make a
       note to look up this information during the follow-up risk assessment,
       if determined necessary.

    •  Complete the "Quantity of Release" portion of the questionnaire.

    •  Fill in the "Release Quantity" columns in the "Facility Risk Screening
       Worksheet."                    ~

                                      4-9

-------
        - Do not  list  "low"  release  quantities of  "high" toxicological potency
         chemicals  unless they  are  determined to  be  persistent.

        - List  "medium"  release  quantities  of  "medium"  toxicological potency
         chemicals  only  if  they are determined to be persistent.

        - Do not  list  "medium" toxicological potency/'low"  release chemicals.

        - At this point,  low and possibly some medium risk  chemicals have been
         screened out.

    Plausible  Routes  of  Exposure

    •   Complete  the "Plausible  Routes  of Exposure" section of the
        questionnaire  for each chemical on  each facility worksheet.

    •   For each  chemical, assign and record under "Plausible Route" a "high"
        or "medium"  ("lows"  have been dropped  in Step One)  likelihood of
        exposure  and level of confidence in each estimate

4.  Rank Relative Risks

    •   Add any chemicals to the facility worksheet which were screened out
        using the above criteria, but for which you have reason to consider the
        need for  further  evaluation  (e.g.,  metal compounds  or other  highly
        persistent chemicals, release points very  close  to  exposure  points,
        chemicals receiving  public attention in your  area).*

    •   If further ranking of chemicals on  the  facility  worksheets is needed,
        the chemicals  that scored "high" in all three columns ("Toxicological
        Potency," "Release Quantity," and "Plausible  Route")  should  be ranked
        at the top of  the risk list.  Those that scored  "high" in  two of the
        three columns  should be  listed next, and those that scored "high"  for
        only one of  the three columns should be grouped  at  the bottom of the
        list.

    •   Compare worksheets for each  organism of concern  and media  of interest
        in order to  rank facilities  according  to their relative risks.

    •   Collect information  necessary to increase  the certainty in estimates of
        toxicological potency, release quantities, or plausible routes assigned
        a "low" or,  in some  cases, a "medium"  level of confidence,  before
       making a decision about  the  need for and focus of a chemical or site
        specific risk  assessment. (See Exhibit  10  for useful  sources of
       information.)
    *To conserve limited resources, keep the number of chemicals  requiring
follow-up risk assessment to a minimum.  If a preliminary  risk  assessment is
necessary on the chemicals you select from the facility worksheets,  it  should
indicate the need to further expand the scope of the assessment to  include
additional chemicals dropped during risk screening.  If, in  the preliminary
quantitative risk assessment, risks associated with your high chemical  risk
candidates are determined to be low, there is no need to further  refine the
risk assessment by addressing chemicals of lower risk potential.

                                      4-10

-------
               THE QUESTIONNAIRE FOR  QUALITATIVE RISK  SCREENING
Instructions;
    Circle the appropriate  response.   If  you  do  not  have enough information to
answer the question, circle "insufficient data.'

    To the left of each question  is a  place to rank  your confidence in  your
answer.  To address your confidence in toxicological potency,  circle H  if  the
exact identity of chemical  and its RQ  are known.   Circle M or  L if  there is
doubt about the chemical's  identity (e.g., chemical  is  identified by generic
name or chemical category),  or if no RQ has been  assigned to the chemical.
For quantity of release, your confidence  will be  higher if you know that
actual monitoring data were used  to derive the estimate given  on Form R and
that the monitoring data were of high  quality, or  if specific  estimates rather
than ranges of releases are reported.   For exposure, circle H  when  your answer
is based on documented evidence and/or high quality  data.  Circle M or  L if
you have some uncertainty about the available information and  your  response.

the emissions reported.]

site-specific factors such as meteorology, topography, and  chemical  release
height.  In general, the higher the average wind speed in the  direction  of
target organisms, the more direct the pathway from the point of  release  to
target organisms (e.g., no intervening mountain ranges or the  target organisms
are not located in a valley over which the chemical plume may  pass without
falling), and the higher the stack from which the chemical  is  discharged, the
further the chemical plume is likely to travel, 'and, in most instances,  the
"closer" the population center or sensitive environment should be considered
to the release point.  As a general guideline, "close" may  vary  from meters up
to a kilometer and distances in excess of 10 kilometers will almost  always  be
"far."  In addition, the physical and chemical properties of a chemical  may
factor into a determination of what is "close" and "far."   Chemicals that are
solids, liquids, or adsorbent gases under ambient environmental  conditions
will tend to fall to the ground closer to the point of release than  inert

into which the chemical is emitted?
                A. Yes
                 B. No
C. Insufficient data
7. Confidence
   H   M   L
If the answer is "yes" to any of questions  1  through  5  above,
is the location of potential exposure:
                A. Very close
                   to the
                   the release?
                 B. Somewhere
                    in between

C. Par from
   release?
              D. Insufficient
                 data
[NOTE:  The determination of "close or  "far" depends  upon  consideration of
site-specific factors such as surface water volume  and  flow rate,  and distance
from the chemical release point.  In general, the smaller  the  stream or river,
the faster the flow rate, and the more  direct the pathway  from the point of
release to target organisms  (e.g., on the same  side of  the river  as a drinking
water intake or recreational area, or near spawning areas  in shallow, quiet
areas of the water body), the "closer"  the location of  potential  exposure
should be considered to the  release point.  In  addition, the physical and
chemical properties of a chemical may factor into a determination  of what is
•close" and "far."  Chemicals that are  soluble  and  persistent  in  water will
migrate further downstream than those that are  volatile or insoluble and
degrade in water.]
8. Confidence
   H   M   L
Do environmental data indicate that the chemical  is
persistent in water (i.e., not likely to be degraded or
otherwise removed from the water)?
                A. Yes
                 B. No
C. Insufficient data
9. Confidence
   H   M   L
If yes, do environmental fate data  (e.g.,  log octanol/water
partition coefficient) indicate that the chemical  is  more
likely to be associated with suspended particulates and
sediments?
                A. Yes
                 B. No
C. Insufficient data
[NOTE;  Adsorption to particles and  sediments would  tend  to  reduce  potential
exposures in drinking water, and increase  exposures  to  "bottom-feeding"
aquatic organisms.  Exposures during water  contact recreational  activities
would depend upon the turbidity in the area of  these activities.]
10. Confidence
   H   M   L
Are monitoring data available that record the  levels  of  the
chemical in ambient water, drinking water, or  in  fish?
                A. Yes
                 B. No
C. Insufficient data

                 monitoring data indicate  that  the  levels  of the chemical were
                 generally:

                 A. Above        B. Below           C.  Insufficient
                   or around       the limit         data
                   the  limit

CONSIDERING THE  ABOVE FACTORS AND THEIR RELATIVE IMPORTANCE, would you say
that the potential for  exposure of individual, population,  or ecosystem to the
emitted chemical is:

                 A. Low

Toxic Chemical Release  Inventory Reporting  Fora  (Form R).  This is the reporting form  industries will  submit  to EPA and the states.  A blank reporting form
is provided In Appendix B.

Roadmaps.  This is a  Section  313 chemical information directory.  Roadmaps can point you to a number of  data  bases snd documents containing information on
health and ecological effects, as well as environmental transport and fate of Section  313 chemicals.   It  also contains Information on Federal and State
regulatory levels for these chemicals, as well as  State contacts for various media (i.e., air, water,  etc.) programs.   A hard-copy version Is provided in
Attachment A.   An on-line version is also available.

Hazardous Substance Fact Sheet.  The New Jersey  Department of Health has developed fact sheets on many Section 313 chemicals.  A sample fact sheet  is
provided In Appendix  D.

Agency for Toxic Substances and Dlsesse Registry (ATSDR) Profiles.  Under SARA Section 110, ATSDR and  EPA are required to develop toxlcologlcal  profiles on
a specified number of hazardous substances  commonly found at facilities on the Superfund National Priorities  List  and  which pose the most significant
potential threat to human health.  The Profiles  contain varied information, including  chemical and  physical properties; health effects; toxlclty;
environmental  fate and  potential for human  exposure; and regulatory status.  Profiles  have been completed for the  following Section 313 chemicals:
chloroform; benzene;  vinyl chloride (monomer); dlchloromethane (methylene chloride); N-nitrosodlphenylamlne;  1.4-dlchlorobenzene; dl(2-ethylhexyl)phthalate
(DEHP); tetrachloroethylene (perchloroethylene);  lead; nickel; arsenic; cadmium; and chromium.  A description of the Profiles Is provided in Roadmaps
(Attachment A).

CEPP Profiles.  These Profiles contain information for chemicals on the EPA list of EHSs, such as acute  hazard Information, chemical properties, and
emergency handling techniques.  A description of  the Profiles Is provided in Roadmaps  (Attachment A).

IRIS.  IRIS is an on-line data base that contains  the latest information about Agency  conclusions on  toxicologlcal potencies, health assessments, and
regulatory decisions  on over  260 chemicals  (about  85 Section 313 chemicals).  It has been designed  specifically for Federal, State, and local environmental
health agencies.  A description of IRIS is  provided in Roadmaps (Attachment A).

Environmental  Transport snd Fate Data Bases.  Descriptions of useful environmental transport and fate  data bases are provided In Roadmaps (Attachment A).
Among these are Envirofate and the Hazardous Substances Data Bank

Exposure Analysis snd Systems.  These systems provide access to data and models used in estimating  chemical fate,  exposed populations, and aggregate
exposure.  EPA has developed  several exposure analysis systems, including the Graphical Exposure Modeling System (PC-GEMS); the Computer-Assisted Management
Emergency Operatlona  (CAMEO); and the Emergency  Information System/Chemical (EIS/C).   These systems run  on PCs and provide access to data management and
analysis tools.  PC-GEMS includes data on selected environmental characteristics (primarily meteorology  and atreams) and population; models for  predicting
concentrations In sir,  water, soil, and ground water; and mapping and graphics capabilities.  CAMEO, which currently runs on a Macintosh, was designed for
first responders to chemical  spills and emergency  planners.  A number of local governments have used CAMEO to load and manage Information on chemicals in
their cities'  facilities, and display this  Information together with locally-entered data on populations, schools, and hospitals.  CAMEO contains two
splll-scensrlo models,  and can display extents of  estimated plumes.  EIS/C, also primarily an emergency  planning system, records chemical, facility,
transportation, vulnerable population, and  other Information.  Check with the contacts listed in Appendix A about  the  availability of these systems.  See
also Appendix G for a more complete description  of PC-GEMS.

Geographic Information  Systems (CIS).  CIS  are computer mapping and analysis systems that can store and  combined multiple "layers" of Information (e.g.,
oeteorologlc,  geologic,  hvdrologlc, demographic,  land use data).  Most CIS run on mainframe systems, and are  used  for  land use planning, although others
which are oriented toward environmental analysis  have been recently Implemented in EPA regions and  several states.  Check with your State and/or Regional
Section 313 contacts  for more Information.

          The Reporting Company.  The reporting company can provide supplementary release Information.   It may also be able to provide monitoring,  toxlcologlcal,  and
          transport and fate data.  Some facilities may also be willing to provide permitting history and files containing Information on  regulatory  compliance.
          Technical and public contacts have been designated for each facility and these contacts are listed on Form R.

          State and Federal Media Programs.  These programs can provide Information on regulation and compliance.  They may also have monitoring  data and/or
          environmental transport and face data.  State programs can tell you If there are State standards for Section 313 chemicals, and  If a particular  release  Is
          permitted.  They may also be aware of a permitted facility's compliance record.  Contacts for State media programs are provided  In Roadmaps (Attachment  A).

          Other.  Various resources are also available, as Indicated.  These include Local Emergency Planning Committees (LEPCs), which have been established across
          the country under Sections 301 to 303 of Title III.  Although LEPCs are not designated to receive Section 313 data, they may have Information about
          facilities, chemicals, and geographic areas of Interest to you.  Land use maps from the U.S.  Geological Survey (USCS) National Cartographic Information
          Center (NCIC) will also be useful, and can be accessed through the National NCIC In Reston, Virginia, as well as USGS Regional offices.  Aerial  photos can
          indicate the chronology of changes in an area's land use and identify indicators of contamination (such as changes In soil conditions and vegetation), as
          well as patterns of dispersion, and a general idea of site environs.  Aerial photos are also archived at USGS.  Ask your EPA Region or  State Section 313
          contact'how to access the appropriate LEPC or nearest USGS Regional office.  The U.S. Department of Agriculture may also be able to provide photographs.
          Additionally, many municipalities periodically conduct aerial surveys, so consult with local authorities.

                  APPENDIX B
TOXIC CHEMICAL RELEASE INVENTORY REPORTING PORN

-------
         APPENDIX B - TOXIC CHEMICAL RELEASE INVENTORY REPORTING FORM
    A facility must submit a separate Toxic Chemical Release Inventory

Reporting Form (hereafter referred to as Form R) for each chemical listed
under Section 313.  A copy of Form R is attached.  Information on Form R that
you should be aware of if you are responding to questions from the public or
conducting risk screening is found in Parts I and III of the form:
PART I
3.1*   Facility Name and Address.  A facility's name and/or location may be
       used to access the TRI data base.  The specific location of a facility
       can also be used to access geographic data bases, which may contain
       information useful for assessing exposure (e.g., meteorological and
       demographic data).

3.3    Technical Contact.  This individual has been designated by the
       reporting company to respond to questions from EPA or State officials
       about information on the Form.   This individual may also be able to
       supply additional information not reported on the Form (e.g., frequency
       and concentration of the release).  The technical contact should not be
       contacted by the public.

3.4    Public Contact.  This person has been designated by the reporting
       company to answer questions from the public.  You can refer citizens
       who have questions regarding Form R to this person.

3.5    Standard Industrial Classification (SIC)  Code.*  The SIC code system
       established by the U.S. Commerce Department classifies business
       "establishments."  Establishments are defined as distinct and separate
       economic activities that are performed at a single physical location.
       Businesses may report separately on the activities involving a toxic
       chemical at each establishment,  or group of establishments, rather  than
       submitting a single Form for that chemical for the entire facility.  A
       box must be checked that indicates whether the report contains
       information about a chemical for an entire facility or for only part of
       a facility.  Facilities that conduct manufacturing operations included
       in codes 20 through 39 are subject to reporting under Section 313.   SIC
       codes may be used to access the TRI data base.
*These numbers correspond to numbers used on Form R to categorize the
information.
                                     B-l

-------
 3.6    Latitude and Longitude.  This information may be used to access
       geographic data bases.  All facilities must provide latitude and
       longitude information for the calendar year 1988, and subsequent
       years.  This information was not mandatory for 1987.

 3.7    Dun and Bradstreet Number.  This is a unique identifying number
       assigned by the Dun and Bradstreet financial firm to facilities and/or
       establishments within facilities.  The Dun and Bradstreet number can be
       used to establish a facility's exact location so as to access
       geographic data bases.

 3.8    EPA Identification Number assigned under the Resource Conservation and
       Recovery Act (RCRA).  The EPA I.D. number is a 12-digit number assigned
       to facilities covered by RCRA hazardous waste regulations.

 3.9    National Pollutant Discharge Elimination System (NPDES) Permit
       Number(s) assigned under Title IV of the Clean Water Act (CWA).  NPDES
       permits are the key to enforcing effluent limitations and water quality
       standards of the Act.  Every point source discharger must obtain a
       permit from either EPA or an authorized State.  Generally, facilities
       and large cities are required to obtain a permit by 1991.  Small cities
       have until February, 1992.  Under these permits, dischargers are
       subject to both technology-based treatment requirements and, where
       necessary to protect a designated use, controls based on water quality
       standards.

 3.11   Underground Injection Well Code (UIC)  Identification Number assigned
       under the Safe Drinking Water Act (SDWA).  (Brief descriptions of SDWA
       and other Federal laws are provided in Appendix E.)

 [NOTE:  The numbers provided in 3.8, 3.9, and 3.11 can help agencies
 investigate regulation for a particular facility.  Toxic chemicals released
 into the environment without permit restrictions or standards can be
 identified.  The information provided on Form R can also be cross-checked with
permit applications.  Additional information  useful for risk screening that is
not reported under Section 313 may be found on these permits.]
PART II
    No information useful for risk screening.
*For more information on SIC codes, consult Standard Industrial Classification
Manual 1987,  available from National Technical Information Service,  5285 Port
Royal Road,  Springfield, VA  22161.  Phone: (703)  487-4650.
                                      B-2

 PART  III

 1.2    Chemical Abstract Service (CAS) Number.  This number identifies the
       chemical released.  You can use it to access the TRI data base, the
       "Roadmaps" Directory (Attachment A), and many health effects data bases.

 1.3    Chemical or Chemical Category Name.  Like the CAS number, the
       chemical's name can be used to access many resources that provide
       information on the chemical, including the TRI data base, the Roadmaps
       Directory (Attachment A), the EPA Hazardous Substance Fact Sheets
       (Appendix D), and chemical data bases.  If a chemical category name is
       given, you will not know exactly which chemical is being released.
       However, you may be able to obtain information about the potency
       characteristics of some chemicals included within the category.

 1.4    Generic Chemical Name.   If the reporting company claims the released
       chemical is a trade secret,  the CAS number and chemical name will not
       be provided.   Instead, the reporting company will provide a generic
       chemical name that is descriptive of the chemical structure.  Since you
       do not know the chemical's exact identity, you will not be able to
       determine its effects and potency.  However, you may be able to
       identify related chemicals that may have similar characteristics.

 2      Mixture Component Identity.*  If the chemical is part of a mixture, the
       reporting company is allowed to identify it using a generic chemical
       name.  As in 1.4 above, this will hamper your ability to characterize
       the effects and toxicological potency of the chemical.   Mixtures also
       present additional difficulties in assessing health or  ecological
       risks.  Unlike a single chemical,  mixtures may or may not exhibit
       distinct toxic effects  or effects characteristic of individual mixture
       components.   Additionally, not all the components of a  mixture may be
       known, and toxicologic  data  on the known components may be scarce.

3      Activities and Uses of  the Chemical at the Facility.  For certain
       chemical uses, it may be possible to estimate the likely rates of
       release, release patterns, and background exposures based on generic
       industry data (see Appendix  C).

5A     Releases of the Chemical to  the Environment.  This part of the Form
       tells you (1)  how much  of the chemical is being released each year, and
       (2) into what media.  Releases are reported in units of pounds per year
       as a range or a single  number, depending on the total quantity
       released.  Five categories of releases are reported:  1) fugitive or
       non-point air emissions;  2)  stack or point air emissions; 3) discharges
       to water (any surface water  bodies or streams into which the chemical
       is directly discharged  must  be reported, and this information is found
       in Part I of the Form,  3.10); 4)  underground injection; and 5) releases
       to land.  The total release  reported for each of these  categories
       includes routine releases and any accidental releases.
*Guidance on assessing the health and ecological risks of chemical mixtures is
provided in the Federal Register, September 24,  1986,  Vol.  51.  pp.
34014-34025.
                                     B-3

-------
 5B     Basis of Estimate.*  Most Section 313 release data will be estimates
       rather than measurements of releases.  Facilities must consider all
       possible sources of release in making their calculations.  This is
       complex if the chemical is made or used in multiple processes.
       Estimation techniques also vary in complexity and reliability.
       Accordingly, so will the accuracy of the estimates generated.  In some
       cases, it may be possible for an estimate to be off by as much as an
       order of magnitude or more.  There are four methods that facilities may
       use in calculating release estimates:

       - Monitoring data.  Monitoring data must be used if accurate and
         readily available.  Section 313 does not require facilities to
         perform additional monitoring, but if data have been collected at a
         facility in accordance with other laws or as part of routine facility
         operations, these data must be used, to the extent possible, in
         estimating releases.

       - Mass balance.  This method can be used for estimating releases when
         monitoring data are not available and when input and output streams
         are quantified.  Mass balance can be performed around entire
         processes or pieces of process equipment.  The mass of material
         leaving a vessel equals the mass entering.  If input and output
         streams are known (based on measured values),  a wastestream can be
         calculated as the difference between input and product (any
         accumulation/depletion of the chemical in the equipment must also be
         accounted for).

       - Published emission factors.   Commonly used for estimating air
         emissions,  emission factors may be based on the average measured
         emissions at several facilities in the same industry.

       - Other approaches.  Other approaches, such as engineering calculations
         (e.g., estimating volatilization or solubility using published
         mathematical formulas),  can also be used.

       Facilities may use more than one of these estimation techniques to
       obtain a single release estimate.   However, Form R simply asks for the
       principal method used to derive an estimate.  If,  for example,  40% of
       the stack emissions of the reported substance were derived using
       monitoring data,  30% by mass balance, and 30% by emission factors,
       monitoring would be the principal method and it  would be entered on the
       Form.   Some understanding  of how facilities derive releases and which
       approaches are most effective  for  each type of release (i.e., likely to
       yield  the most accurate estimates)  is useful to  assessing the accuracy
       of the reported data.
*For more information on estimation techniques and their relative
effectiveness,  see EPA's Estimating Releases and Waste Treatment Efficiencies
for the Toxic Chemical Release Inventory Form (a complete citation is provided
in the Bibliography.)

b.  Instructions.
                      INSTRUCTIONS FOR COMPLETING EPA FORM R,
                    THE TOXIC CHEMICAL RELEASE REPORTING FORM
GENERAL INFORMATION
A  complete  report Form R must be submitted for  each
toxic chemical manufactured, processed, or otherwise  used
at  each covered  facility  as  prescribed in the  reporting
rule in 40 CFR Part 372.  These instructions  supplement
and elaborate  on  the  requirements  in  the reporting  rule.
Together with  the  reporting  rule,  they  constitute  the
reporting  requirements;  you   should  read both  before
attempting  to  complete Form R.  All  references in these
instructions  are to  sections in  the  reporting  rule unless
otherwise indicated.

The Toxic Chemical Release Reporting Form, EPA Form R,
consists of four parts:

 -  Part I, Facility  Identification Information;
 -  Part II,  Off-Site  Locations  to Which Toxic
   Chemicals are Transferred in Wastes;
 -  Part III, Chemical Specific Information; and
 -  Part IV, Supplemental Information.

Form  R is designed  so that a majority of the  information
required in Part I and all of the information  required in
Part II should be  the  same for each chemical reported by
your facility.  If  the  information in Parts I  and II are
identical  for two or  more chemicals,  you may  submit
photostatic  copies of  those parts for those chemicals  as
long as each  Part  I  has an original  signature on  the
certification  statement.    Part III  must be  completed
separately for each chemical.   Part IV  provides additional
space,  if needed, to  complete  the information required by
the preceding sections of the form.

A  complete  report for any listed toxic  chemical that is
not  claimed  trade   secret   consists  of  the  following
completed parts:

 -  Part I with an' original signature  on the
   certification statement (Section 2);
 -  Part II;
 -  Part III (Section 8 is optional); and
 -  If applicable, Part IV.

A  complete report  for  a toxic chemical claimed  trade
secret includes all of the above items plus the following:

 -  A completed trade secret substantiation form;
 -  A  "sanitized"  version  of  the report  in  which  the
   chemical  identity  items  (Part III,  Sections  1.2 and 1.3)
   have been left  blank but  in which  a generic chemical
   name has been supplied (Part III, Section 1.4); and
 -  A "sanitized" version  of the trade secret substantiation
   form.

WHEN THE REPORT MUST BE
SUBMITTED

The report for any calendar year must be  submitted on or
before  July  1  of  the  following year (e.g., the report for
calendar year  1987,  January through December, must be
submitted on or before  July 1, 1988).

WHERE TO SEND THE REPORT

Submit reports, including  reports containing  trade secret
claims  (i.e., sanitized) to:
     U.S. Environmental Protection Agency
     P.O. Box 70266

In addition, you must send a copy of the  report to the
State (State of the U.S.,  the District of Columbia, the
Commonwealth  of Puerto Rico, Guam, American Samoa,
the U.S. Virgin Islands, the Northern  Mariana Islands,
and  any other territory  or possession over which the
U.S.  has jurisdiction)  in  which  the  facility is located.
States  will provide addresses where  the copies  of the
reports are to be sent.  Copies of the report sent to the
State should be the "sanitized."  non-trade-secret version
of the  report,  unless the State  specifically requests
otherwise.    For  additional information,  refer to  the
discussion  of trade secret/confidentiality  claims  in the
instructions  for  completing Part HI, Section 1,  of the

INSTRUCTIONS FOR COMPLETING
SPECIFIC SECTIONS OF EPA FORM R

The  following  are specific instructions for completing
each section of EPA  Form R. The number designations
of  the  parts   and   sections   of   these   instructions
correspond   to   those  in  Form  R  unless  otherwise
indicated.

PART I.  FACILITY IDENTIFICATION
INFORMATION

1.1  Does This, Report Contain Trade Secret
     Information?

You  must  answer this question only after you  have
completed the rest of the report.  The specific identity
of the toxic chemical being reported in Part III, Sections
1.2 and 1.3 may be  designated  as  trade secret.  If you
are making a trade secret  claim,  answer by marking the
"yes" box and  proceed to Section 1.2.   (See  Part III,
Section  1,  of these instructions for specific  instructions
on trade secrecy claims.)  If the answer is  no, proceed
to Section 1.3.

1.2  Is This a Sanitized Copy?

You  must  answer this question only after you  have
completed the  rest of  the report.   Answer yes  if this
copy of the report is the public  "sanitized" version of a
report  where  the  chemical identity  is  claimed  trade
secret in Part  III,  Section 1.4 of the  report.  Otherwise,
answer no.
                                                    B-10

-------
1.3  Reporting Year
3.4  Public Contact
In  Section  1.3,  you  must  enter the  year to which  the
reported information  applies,  not  the  year in which you
are submitting the report.

2.  Certification

The certification  statement  must be signed by the owner
or  operator,  or   a   senior  official  with  management
responsibility for the person  (or persons)  completing  the
form.   The owner, operator,  or official must  certify  the
accuracy and completeness of the information reported on
the form by signing and dating the  certification statement.
Each report must contain an  original signature.  Print or
type  the  name  and  title  of the  person  who signs  the
statement  in  the  space  provided.    This  certification
statement applies to  all the information supplied on  the
form  and should be signed  only after the  form has been
completed.

3.  Facility Identification

3.1 Facility Name and Location

You must enter  the name of your facility (plant site name
or  appropriate facility  designation), street address, city,
county, state,  and  zip code in  the space provided.  You
may not  use a  post  office  box number for this location
information.  The address provided should  be the location
where   the  chemicals are  manufactured,   processed,  or
otherwise used.

3.2 Full or Partial Facility Indication

You must indicate whether  your report is  for the covered
facility  as  a  whole  or  for part  of  a covered facility.
Check box  a.  if the  report contains information about a
chemical for an entire covered  facility.  Check box b. if
the report contains information about a chemical but  for
only part of a covered facility.

The SIC  code system classifies  business "establishments,"
which  are  defined  as  "distinct and  separate economic
activities  [which]  are  performed  at   a   single  physical
location."   Under section S72.30(c) of the reporting rule,
you may  choose  to submit a separate Form R for each
establishment,  or for  groups  of establishments, in your
covered facility.   This allows  you  the  option  of reporting
separately on  the activities  involving a toxic chemical at
each establishment, or group  of establishments (e.g., part
of  a  covered  facility), rather  than  submitting  a  single
Form R for that chemical  for  the entire facility.  You
may  do  this  provided  that  all  releases of  the  toxic
chemical from  the entire  covered facility are reported.
However,  if an establishment  or group of establishments
does not manufacture, process, otherwise use,  or release a
toxic  chemical, then you do not have to submit a  report
on  that chemical from  that  establishment  or group of
establishments.

3.3 Technical Contact

You must enter the name and  telephone number (including
area code)  of a technical  representative  whom EPA or
State  officials   may  contact  for  clarification of   the
information  reported on the form.  This person does  not
have  to be  the  person who prepares the  report or signs
the certification statement.   However, this  person  must
have  detailed  knowledge of  the  report   to  be able to
respond to questions.
You must  enter  the  name  and  telephone number of  a
person who can  respond to questions from  the  public
about the report.   If you choose to  designate the same
person as  both the  technical  and  the public contact,
enter "same as  3.3" in this space.  If no public contact is
designated  in  Section 3.4,  EPA  will  treat the technical
contact as the public contact.

3.5  Standard Industrial Classification
     (SIC) Code

You must enter the appropriate 4-digit primary Standard
Industrial Classification  (SIC) code for your facility.   If
the report covers more than one  establishment, enter  the
primary  4  digit SIC  code for each establishment.  You
are only required  to  enter SIC  codes for establishments
within the  facility that fall within SIC codes 20 through
39 as identified in section 372.22 of the reporting rule.
Use the Supplemental Information sheet (Part IV) if you
need to enter more than three SIC  codes.

3.6  Latitude and Longitude

Enter the latitudinal and longitudinal coordinates of your
facility.   You must supply the latitude and  longitude for
calendar  year  1987 reports  if the information  is readily
available to you.   Sources  of these data include EPA
permits  (e.g., NPDES permits), county property records,
facility blueprints,  and  site plans.  If these  geographic
coordinates are not readily available to you for calendar
year  1987  reports,  enter  not  applicable  [N/A].    All
facilities  are required to  provide this information  in
reports   submitted for   the calendar  year  1988  and
subsequent  years.  Use leading place holding zeros.

3.7  Facility Dun and Bradstreet Number

You  must   enter  the number   assigned by   Dun  and
Bradstreet  for your facility or each establishment  within
your facility.  This may  be  available  from your facility's
financial  office.   If none  of your establishments have
been assigned Dun and Bradstreet Numbers, indicate this
in Section 3.7  by entering not applicable [N/A] in  box a.
If only some of your establishments  have been assigned
Dun and Bradstreet numbers, indicate this in Section  3.7
by  entering those numbers.   Use leading  place  holding
zeros)    For more  than two  establishments,  use   the
Supplemental Information sheet (Part IV).

3.8  EPA Identification Number

If your  facility has  been  assigned  EPA Identification
Numbers, you  must enter those numbers.  The EPA I.D.
Number  is  a  12-digit  number  assigned  to  facilities
covered   by  hazardous  waste   regulations  under   the
Resource  Conservation   and  Recovery  Act  (RCRA).
Facilities not covered by  RCRA are not likely  to have an
assigned  EPA I.D. Number.  If your facility does not have
an EPA I.D. Number, enter not applicable [N/A] in box a.
If your  facility has  more than  two  numbers, use  the
Supplemental Information sheet  (Part IV).  Use leading
place holding zeros.

3.9  NPDES  Permit Numbers

receiving stream to which  chemicals being reported  are
directly  discharged.   Report the name of  each receiving
stream or water body as it appears on the NPDES permit
for  the   facility.   Enter  not  applicable  [N/A]  to  any
unneeded spaces.   If your  facility discharges the toxic
chemical to  more than three receiving streams or  water
bodies, use the Supplemental Information sheet (Part IV).

3.11  Underground Injection Well Code
      (UIC) Identification Number

If  your facility  has  a   permit  to  inject  chemical-
containing waste which includes any toxic  chemical being
reported into  Class  1  deep  wells, you must enter  the
Underground Injection Control (UIC) 12-digit identification
number  assigned  by EPA or by  the State  under  the
authority of the Safe Drinking Water Act.  If your facility
does not hold such a permit, enter not applicable [N/A] in
this space.

4. Parent Company Information

leading place holding zeros.

PART II.  OFF-SITE LOCATIONS TO
WHICH TOXIC CHEMICALS ARE
TRANSFERRED IN WASTES

This  section requires a listing of all  off-site locations to
which you transfer wastes containing the toxic chemical.
The information that you  enter in this section relates to
data to  be reported in Part III, Section 6, of the form.
List only publicly  owned treatment works (POTW)  and
treatment or  disposal facilities.  Do not list locations to
which products containing the toxic chemical  are shipped
for sale  or distribution in  commerce  or for further use.
Also,  do not list locations to which wastes  containing the
chemical are sold  or sent for recovery, recycling, or reuse
of the toxic chemical.

1. Publicly Owned Treatment  Works
   (POTW)

You must enter the name and address of  the POTW to
which your facility discharges wastewater containing  any
toxic  chemical you are reporting.  If you do not discharge
     vj.-_, -•'..••'•,-u, ..... .,'•;< .•••.>•  ?-'',--r~  t, (rpnrv

POTW, use additional copies of Part II. •

2. Other Of f-Site Locations

In  the  block  next  to  the  heading  "Other off-site
location,"  enter a  number.   For  the first  such off-site
location enter "1" in the block.  Continue numbering the
off-site locations in ascending order.   This  is the block
number required by Part III,  Section 6.  If your facility
transfers  the  toxic chemical to  more than three off-site
locations,  use additional copies  of Part II and continue
numbering these locations in ascending order.

In the  spaces provided, you  must enter  the name  and
address of each location (other  than POTWs)  to which
you  ship  or  transfer  wastes  containing the  toxic
chemical.  Also enter the RCRA I.D. Number (EPA  I.D.
Number)  for each such location, if known to you.  Such
information may  be found on  the Uniform Hazardous
Waste Manifest which is required by RCRA regulations.

You must also indicate in the space provided whether the
location is owned or controlled  by your  facility or your
parent  company.

PART III.  CHEMICAL SPECIFIC
INFORMATION

1.1 Trade Secret Block

If you  are claiming chemical  identity as a  trade secret,
you must  mark the trade secret claim box in Section  1.1.
In addition, you  must attach a completed  trade secret
substantiation  form to the report,  as set  forth  in  the
trade   secret  rule  in  40 CFR  Part 350.   When  the
chemical  identity  is claimed trade secret, you must  also
provide a generic name in Section 1.4.

Note:   If you complete and submit your  Toxic  Chemical
Release Inventory Reporting Form before  the trade secret
rule is in effect,  you are still  required  to  substantiate
your claim that the specific chemical identity is a trade
secret.  Accordingly, you  should follow the  provisions of
the proposed trade secret  rule  and use the  proposed
trade secret substantiation form  which  appeared isi  the
FEDERAL REGISTER of October 16, 1987 (52FR 38312-
38377).

1.2 CAS Registry Number

You  must enter the Chemical Abstracts  Service (CAS)
registry number  that  appears  in  section 372.65  of  the
reporting  rule for the chemical  being  reported.    Use
leading place  holding  zeros. If you are reporting one of
the chemical  categories in section  372.65  of  the   rule
(e.g., copper compounds), enter [N/A] in the  CAS number
space.    CAS  numbers  are  cross-referenced  with   an
alphabetical list of trade names and chemical  names in
section 372.65 of the rule.

1.3 Chemical or Chemical Category Name

You must enter in the space provided the  name of the
chemical  or chemical category as  it  is listed in section
372.65  of the reporting rule.  Only use  names listed in
section  372.65.

1.4 Generic Chemical Name

You must complete Section 1.4 if you are  claiming the
specific chemical  identity  of the  toxic  chemical  as  a
trade secret and have marked the  trade secret block in
                                                     B-12

-------
Section  1.1.    The  generic   chemical  name  must  be
descriptive of the chemical structure.  You must limit the
generic name to seventy characters (e.g., numbers, letters,
spaces, punctuation) or less.

2.  Mixture Component Identity

Use this section to report  a mixture  component that you
know exceeds a threshold.  Do not complete this section
if you have completed Section 1 of Part III.

You may have received a mixture or trade  name product
from another  person  which you  were  told contains  a
section 313 toxic chemical, but that person did not tell
you the specific  chemical  name or CAS number of the
toxic chemical.  The person may have given you a generic
chemical  name  and the percentage  composition  of the
toxic chemical in  the mixture or trade name  product under
section 372.45  of the  reporting rule.   If you determine
that you  have  imported, processed, or otherwise used the
toxic chemical  in the mixture  or  trade  name product in
excess  of  an applicable  threshold,  you  must enter the
generic chemical  name  given to you  by your supplier in
Section 2.  If  your  supplier did not give  you  a  generic
chemical name, you  must  enter the  name  by .which the
supplier  identified the  chemical to you.   (In some cases,
this may be the same as the name of the mixture or  trade
name product.)

For example, your facility uses  20,000 pounds of a solvent
which  your supplier has told you  contains eighty  percent
"chlorocyclocarbon,"  his  generic  name  for  a  chemical
subject to reporting  under section 313.    You therefore
know that you have exceeded  the use  threshold for this
toxic   chemical.      You   would  enter   the    name
"chloroeycloearbon," in the space provided in Section 2.

3.  Activities and Uses of the Chemical at
    the Facility

This   section   requires   an indication   of  whether  the
chemical is manufactured (including imported), processed,
or  otherwise used at the  facility  for  which the form  is
being filed and the general nature of such  activities and
uses at  the  facility during the calendar  year.   Report
activities  that  take  place only  at  your  facility,  not
activities that take place at other  facilities involving your
products.   You must mark all of the appropriate blocks in
this Section that apply to the  activities at your facility.
Refer to the definitions of "manufacture," "process," and
"otherwise  used" in section 372.3 of the reporting rule for

5.4  Underground injection

You  must enter the  total annual amount of the chemical
that  was injected into wells, including Class I and other
types, at the facility.

5.5  Releases to land

You  must  report  quantities of the chemical  that  were
landfilled, impounded, or  otherwise disposed  of  at  the
facility.  Do not report land disposal at  off-site locations
in this section.  You must enter the appropriate disposal
code from the following list:
If the  toxic chemical was present at your facility as part
of a. mixture or trade name  product,  to  determine the
maximum quantity of the chemical  present at the facility
you must calculate only the weight  of the toxic chemical,
not  the weight  of the  entire  mixture or  trade  name
product.  See section  372.30(b)  of  the  reporting rule for
further information on how  to calculate  the weight of the
chemical in the mixture or trade name product.

5. Releases of the Chemical to the
    Environment

In Section 5  you  must account  for  the  total  aggregate
releases of the toxic   chemical from  your facility to the
environment  for the  calendar year.   Releases to  the
environment  include  emissions  to the  air, discharges to
surface waters,  and  releases  to  land  and  underground
injection wells.

All air releases of the chemical from  the facility must be
covered. In case of doubt about  whether an  air release is
a  point or non-point  release,  it is  important  that the
release  be included  as one or  the  other  rather  than
omitted. Do not enter information on individual emission
points  or releases. Enter only the total release.

5.1  Fugitive or non-point air emissions.

These   are releases to  the  air  that  are  not  released
through stacks, vents, ducts, pipes,  or any other confined
air stream. You must include (1) fugitive equipment  leaks
from valves,  pump seals,  flanges, compressors,  sampling
connections, open-ended lines,  etc.;  (2)  evaporative losses
from  surface  impoundments; (3) releases  from building
ventilation   systems;   and  (4)  any  other  fugitive  or
non-point air emissions.

5.2  Stack or point air  emissions.

These  are  releases to  the  air  that  are through  stacks,
vents,  ducts,  pipes, or other confined air streams.  You
must  include  storage  tank  emissions.   Air releases  from
control equipment would generally fall in this category.

5.3  Discharges to water

You   must  enter  the  applicable  letter code for  the
receiving stream or water body from Section  3.10 of Part
I of the form.   Also,  you  must enter  the  total  annual
amount of  the chemical released  from all discharge points
at the  facility to  each  receiving stream or  water  body.
You  must include process outfalls such as pipes  and  open
trenches,  releases  from  on-site  wastewater  treatment
systems, and  the  contribution from stormwater runoff if
applicable (see instructions  for column C below). Do not
include "indirect" discharges to surface  waters such as to
a POTW or off-site wastewater treatment facility.  These
must be reported in Section 6.
                                              Disposal Codes

                                            D02  Landfill
                                            DOS  Land Treatment/Application/Farming
                                            DOS  Surface Impoundment (to be closed as a
                                                 Landfill)
                                            D99  Other Disposal

                                     Three  lines  are  provided  in  this section  of the  form to
                                     accommodate various types of land disposal.

                                     For the purpose of this form,  a surface impoundment is
                                     considered  "final disposal."   Quantities of the  chemical
                                     released to surface impoundments that are used merely as
                                     part of a  wastewater treatment process  generally must
                                     not be reported in this section  of the form.  However, if
                                     the  impoundment  accumulates  sludges  containing  the
                                     chemical,  you must include  an estimate in this section
                                     unless  the sludges  are removed and otherwise disposed of
                                     (in which  case  they  should  be  reported  under  the
                                     appropriate  section of the form).  For the purposes of
                                     this reporting, storage tanks are not considered  to be  a
                                     type of  disposal  and are  not to be reported  in  this
                                     section of the form.

                                       A.  Total Release

                                     Only releases  of the  toxic chemical  to the environment
                                     for the calendar year  are to be reported in this section
                                     of the form.   The total  releases from your facility do
                                     not include transfers  or shipments  of the chemical from
                                     your facility for sale or distribution  in commerce or of
                                     wastes  to other facilities  for  treatment or disposal  (see
                                     Section 6.1).  Both routine releases,  such as fugitive air
                                     emissions, and accidental or non-routine releases, such as
                                     chemical spills, must  be included in your estimate of the
                                     quantity released.

                                       A.I  Reporting Ranges

                                     For reports  submitted for calendar years 1987, 1988,  and
                                     1989 only, you may take advantage of range reporting for
                                     releases that are less than 1,000 pounds  for the year to
                                     an environmental  medium.   You may mark one of the
                                     three   boxes,  0,   1-499,   or  500-999,  corresponding  to
                                     releases of  the  chemical  to  any environmental  medium
                                     (i.e., any line item);  however,  you do not  have to use
                                     these   range check  boxes.    You  have  the  option of
                                     providing a specific figure  in  column  A.2  as described
                                     below.

                                     For releases of 1,000 pounds or more  for the year to any
                                     medium, you must provide an estimate in pounds  per year
                                     in column A.2. Any estimate provided  in column A.2 is
                                     required to be accurate to no more than two significant
                                     figures.  Beginning with reports for  calendar year 1990,
                                     you may  not use  ranges  to report;  you  must report in
                                     column A.2.
                                                       B-14

-------
  A.2 Enter Estimates

You must provide your estimates of releases in pounds for
the year in column  A.2.   This estimate is required  to  be
accurate to no more than two significant figures.

  Calculating Releases

To  provide  the  release  information  required  in  both
Sections A.I  and A.2 in this section of  the form, you must
use   all  readily  available   data  (including  relevant
monitoring data and emissions measurements) collected  at
your  facility pursuant  to other provisions  of law  or  as
part of routine plant operations, to the extent you have it
for the toxic chemical.

When relevant monitoring data or emission  measurements
are  not  readily available,  reasonable  estimates of the
amounts released must be made using published emission
factors,  material  balance  calculations,  or  engineering
calculations.    You  may  not use  emission  factors  or
calculations to estimate releases if more accurate data are
available.

No additional monitoring or measurement of the quantities
or concentrations of  any toxic chemical released into the
environment,  or of  the  frequency  of such  releases,  is
required for  the  purpose  of completing this form, beyond
that  which  is  required under other  provisions  of law  or
regulation or as part of routine plant operations.

You must estimate as accurately as  possible the quantity
in pounds  of the chemical  or chemical  category that  is
released annually to each environmental medium.  Do not
include the  quantity  of components of a  waste stream
other than the toxic chemical in this estimate.

If the toxic chemical was present at your facility as part
of a  mixture  or  trade name  product, you  must calculate
the releases of the chemical only.  Do not include releases
of the other  components of the  mixture or  trade  name
product.   If you only know  about  or are only  able  to
estimate  the releases  of  the mixture  or  trade  name
product as  a  whole, you must  assume  that  the  toxic
chemical is released  in proportion  to its concentration  in
the mixture or trade  name product.   See section S72.SO(b)
of the reporting rule for further information on how  to
calculate the concentration and weight of the chemical  in
the mixture or trade name product.

If you are  reporting  a chemical category listed  in section
372.65(c)  of  the  reporting rule  rather  than  a  specific
chemical,  you must combine  the   release  data  for  all
chemicals  in  the listed chemical category (e.g., all glycol
ethers or  all  chlorophenols)  and  report  the  aggregate
amount for  that chemical  category.    Do  not  report
releases of  each  individual  chemical  in  that  category
separately.    For example,  if  your facility  releases  3,000
pounds per year of 2-chlorophenol, 4,000 pounds per year
of  S-chlorophenol,   and  4,000  pounds  per   year   of
4-chlorophenol,  you  should  report  that  your  facility
releases 11,000 pounds per year of chlorophenols.  (Other
than  for listed chemical  categories  in section 372.65(c)  of
the  rule,   each  form  must  report  for  an   individual
chemical.

Listed chemicals with  the  qualifier "solution," such  as
sodium sulfate, in  concentrations of  1 percent  (or 0.1
percent in  the case  of a carcinogen) or greater, must be
factored into  threshold  and release  calculations,  because
threshold  and  release amounts relate  to  the  amount  of
chemical in solution, not the amount of solution.

For   metal   compound    categories   (e.g.,    chromium
compounds), report  releases  of only the  parent metal.
For  example,  a user of various inorganic chromium salts
would report  the  total chromium released  in  each waste
type regardless of the chemical form (e.g.,  as the original
salts,  chromium  ion,  oxide,  etc.),  and   exclude  any
contribution to  mass  made  by  other species  in  the
molecule.

  B. Basis of Estimate

For  each release  estimate  you are required  to  indicate
the principal method by which the  quantity was derived.
Enter  the  letter  code to identify the  method  which
applies  to  the  largest  portion of the  total estimated
quantity.

For  example, if 40 percent  of stack  emissions  of the
reported substance  were  derived  using  monitoring data,
30 percent by mass balance,  and  30 percent by emission
factors,  you  would  enter  the  code  letter  "M"  for
monitoring.  The codes are as follows:

  M - Based on monitoring data or measurements for the
       toxic chemical  as  released  to  the environment
       and/or off-site facility.

  C -  Based  on   mass  balance   calculations,  such  as
       calculation of the amount of the toxic  chemical in
       streams entering and leaving process equipment.

  E -  Based on published emission  factors, such as those
       relating  release  quantity  to   throughput   or
       equipment type (e.g., air emissions factors)

  O -  Based  on  other approaches such  as  engineering
       calculations  (e.g.,   estimating   volatilization  or
       solubility using  published mathematical formulas)
       or best engineering judgment.  This would include
       applying an  estimated  removal  efficiency to  a
       wastestream  even  if  the  composition of  stream
       before   treatment  was fully  characterized  by
       monitoring data.

If the monitoring  data, mass balance, or emission  factor
used to  estimate the release  is not specific to the toxic
chemical, the  estimate should  be  reported as based on
engineering calculations or judgment.

  C.  Percent From Stormwater

This column only relates to  Section 5.3 -  Discharges to
Water.   The  quantity of the  chemical released to  any
receiving stream or  water body in each  box in column A
must  include  the  amount  contributed by  Stormwater
runoff from  the facility which contains the chemical.  In
addition, the percentage of the total quantity (by weight)
of the  chemical  contributed  by   Stormwater must be
entered in  column  C.   If your facility has  monitoring
data on  the .chemical and  an estimate of flow rate, you
must use this data to determine percent Stormwater.

If your facility does not  have  periodic  measurements of
Stormwater  releases of the chemical but  has submitted
chemical specific  monitoring data in permit applications,
then  these  data  must  be  used to  calculate the percent
contribution from Stormwater.   Flow rate  data can be
estimated by  multiplying  the annual amount of rainfall
times the land  area times the runoff  coefficient.   The
runoff coefficient represents the fraction of rainfall that
does not  infiltrate into the ground but runs off as
Stormwater.   The  runoff coefficient  is directly related to
the land  uses located  in  the drainage  area  and ranges
from  0.5-0.8 for  light  industrial  areas and  0.6-0.9 for
heavy industrial areas.  Site  specific determinations  can
                                                        B-15

-------
be calculated using the following formula:

(1 x fractional paved or roofed area)  + (0.2 x fractional
grass area) +  (0.3 x fractional graveled area) = site runoff
coefficient

If you  have monitored stormwater but did not detect the
chemical,  enter  zero  (0) in  this space.   If your facility
has  no  stormwater  monitoring  data  for  the  of  the
chemical, enter no data [N/D] in this space on the form.

6. Transfers of the Chemical in Waste to
    Of f-Site Locations

You  must report in this section the total annual quantity
of the  chemical sent  to  any  of the  off-site  disposal,
treatment,   or  storage  facilities  for  which  you   have
provided an address in Part II.

Line 6.1 is  for transfers to a POTW.  Lines 6.2 through
6.4 are provided for transfers  to  other  off-site locations,
including privately  owned  wastewater  treatment facilities.

Enter,  from Section 2 of  Part II, the block number that
corresponds  to  the  off-site   location   to  which  you
transferred  waste containing the chemical.   If you  need
additional space (i.e., you  ship  waste  to more than three
off-site  locations),  check  the  box  at  the  bottom  of
Section 6  and  use  the Supplemental  Information  sheet
(Part IV).

  A.  Total Transferred

You  must  follow the instructions  for  providing estimates
as presented in the instructions  for column A of Section 6
above.   You must enter the amount in pounds of only the
toxic chemical  that is being  transferred;  do not enter the
total  poundage of wastes,  including  mixtures or  trade
name products containing  the chemical.   As with Section
5, you may report in ranges  only for  calendar years 1987,
1988, and 1989.                                       *

  B.  Basis of Estimate

You  must identify the basis for  your estimate.  Follow the
instructions and use  the same  codes  as presented  in the
instructions for column B of Section 5.

  C.  Type of Treatment/Disposal

You  must enter one of the following codes to identify the
type of treatment or disposal method used by the off-site
location for the chemical being  reported.  You may  have
this information in your copy of EPA Form SO, Item S of
the Annual/Biennial Hazardous Waste  Treatment, Storage,
and  Disposal  Report  (RCRA).  Applicable  codes for this
section are as follows:

     M10 Storage Only
     M20 Reuse as Fuel/Fuel Blending
     M40 Solidification/Stabilization
     M50 Incineration/Thermal  Treatment
     M61 Wastewater Treatment (Excluding POTW)
     M69 Other Treatment
     M71 Underground Injection
     M72 Landfill/Disposal Surface Impoundment
     M73 Land Treatment
     M79 Other Land Disposal
     M90 Other Off-Site Management
     M91 Transfer to Waste Broker
     M99 Unknown

7. Waste Treatment Methods and Efficiency

In Section 7,  you must provide the following information
related  to   the   chemical  whose  releases  are  being
reported:  (A)  the general wastestream types containing
the chemical being reported;  (B) the waste  treatment
methods (if  any)  used  on all wastestreams containing the
chemical; (C) the range of concentrations of the chemical
in the influent  to the  treatment. method  (D)  whether
sequential  treatment  is used;  (E)  the   efficiency  or
effectiveness of each treatment method in removing the
chemical; and (F)  whether the  treatment efficiency  figure
was based  on actual operating data.   You must  use  a
separate  line in  Section 7  for each  treatment  method
used on a  wastestream.  This section is to be  used to
report  only  treatment of wastestreams at  your  facility,
not treatment off-site.

  A.  General Wastestream

For  each  waste  treatment  method  report  you  must
indicate the type of wastestream containing the chemical
that is treated.   Enter the  letter code that corresponds
to the general wastestream type:

  A =  Gaseous (including gases, vapors, airborne
       particulates)
  W = Wastewater (aqueous waste)
  L =  Liquid waste (non-aqueous waste)
  S =  Solid waste (including sludges and slurries)

If a waste is a mixture of water and organic  liquid,  you
must  report it  under  wastewater unless  the  organic
content  exceeds   50  percent.    Slurries   and  sludges
containing water  must be reported as  solid  waste if they
contain appreciable amounts  of dissolved solids, or  solids
that may settle, such that the  viscosity or density of the
waste  is  considerably  different  from that  of  process
wastewater.

  B.  Treatment Method

Codes  for treatment methods  are  included in Table I of
these  instructions.   You must enter  the code  for  each
treatment  method used on a wastestream containing the
toxic  chemical,   regardless  of  whether this  treatment
method  actually   removes   the   specific   chemical.
Treatment  methods  must be reported by type  of  waste
being treated (i.e., gaseous wastes, aqueous wastes,  liquid
non-aqueous wastes, and solids).

Wastestreams containing the chemical  may  have  a  single
source  or  may  be  aggregates  of many sources.    For
example, process  water from several pieces  of equipment
at  your facility  may  be combined prior  to treatment.
Report treatment  methods that  apply to  the aggregate
wastestream as well as treatment  methods  that apply to
individual wastestreams.  If your facility treats various
wastewater  streams  containing the chemical in different
ways,  the  different treatment  methods  must  each  be
listed separately.

Your  facility may  have several  pieces of equipment
performing   a similar  service.   It  is not  necessary to
enter  four lines of data  to cover four  scrubber units, for
example,  if  all  four  are  treating  wastes  of similar
character (e.g.,  sulfuric acid mist emissions), have similar
influent concentrations, and have similar removal
efficiencies.   If,  however, any  of these parameters  differ
from one unit to the next,  each  scrubber must be  listed
separately..

  C.  Range of Influent Concentration

The  form   requires  an indication  of  the  range  of
concentration of the toxic  chemical in  the wastestream
(i.e., the influent)  as it typically enters the  treatment
equipment.  You  must enter in the space provided one of
                                                       B-16

-------
the  following  code   numbers   corresponding   to   the
concentration of the chemical in the influent:

     1 = Greater than 1 percent
     2 = 100 parts per million (0.01 percent) to 1 percent
        (10,000 parts per million)
     3 = 1 part per million to 100 parts per million
     4=1 part per billion to 1 part per million
     5 = Less than 1 part per billion

Note that parts per million (ppm) is milligrams/kilogram
(mass/mass) for solids  and liquids; cubic centimeters/cubic
meter  (volume/volume)  for   gases;  milligrams/liter  for
solutions  or  dispersions of  the  chemical in  water;  and
milligrams of  chemical/kilogram  of air for participates in
air.  If you have participate concentrations (at  standard
temperature and  pressure)  as grains/cubic foot  of  air,
multiply  by 1766.6 to convert to parts per million:  if in
mg/m  , multiply by  0.773 to obtain ppm.  (Note:  Factors
are for standard conditions  of O°C (S2°F) and 760 mmHg
atmospheric pressure).

  D.  Sequential Treatment?

You may use  various  treatment steps  in  a  sequence  but
only be  able  to estimate the  treatment  efficiency of the
overall treatment process.   If  this is the  case, you must
enter  codes for all of the treatment  steps in the process.
You must check the  column D  "sequential treatment?"  box
for all of these steps in the same sequence.  With respect
to information that must be supplied  in columns C and E,
you  must  provide  the range  of influent  concentrations
(column  C)  in connection  with the  first  step  of  the
sequential  treatment.     Then  provide  the   treatment
efficiency  (column E) in connection with the last  step in
the treatment.  You do not need to  complete  C or E for
any intermediate step in the sequence.

  E.  Treatment Efficiency Estimate

In the space provided, you must enter the number that
indicates  the  percentage  of the toxic  chemical that is
removed  from the wastestream.  The treatment efficiency
(expressed as percent removal) represents any destruction,
biological degradation,  chemical  conversion, or  physical
removal  of  the  chemical  from  the wastestream  being
treated.   This efficiency  must  represent  the  mass or
weight percentage of chemical  destroyed  or  removed,  not
just changes  in volume or  concentration of the  chemical
or  the  wastestream.    The   efficiency  indicated for  a
treatment  method  must   refer  only  to  the   percent
conversion  or  removal of the  listed  toxic chemical from
the wastestream, not the percent conversion  or removal of
other  wastestream constituents  (alone or together with the
listed  chemical),  and  not  the general  efficiency  of  the
method for any wastestream.

For some treatments,  the percent removal will represent
removal   by   several   mechanisms,   as   in  secondary
wastewater treatment, where a  chemical may  evaporate, be
biodegraded, or be physically removed  in the sludge.

   Percent removal must be calculated as follows:

     (I-E)  x  100
       I
where 1 = mass of the chemical in the influent
wastestream and E = mass  of the chemical in the effluent
wastestream.

The mass or weight  of chemical  in the wastestream being
treated   must  be   calculated  by   multiplying   the
concentration   (by   weight)  of  the  chemical   in   the
wastestream times the  flow rate.    When  calculating or
estimating   percent  removal  efficiency  for  various
wastestreams,  the  percent  removal  must  compare  the
gaseous effluent from treatment to the gaseous influent,
the  aqueous  effluent  from  treatment to  the  aqueous
influent,  and similarly for organic  liquid and solid waste.
However, some treatment methods may  not  result  in a
comparable  form  of effluent  wastestream.   Examples are
incineration or solidification  of wastewater.    In  these
cases,  the  percent  removal  of the  chemical from  the
influent wastestream would be  reported  as 100 percent
because the wastestream does not exist in  a  comparable
form after treatment.

Some of  the treatments listed in Table I  do not  destroy,
chemically  convert,  or  physically  remove  the chemical
from  its  wastestream.    Some  examples  include   fuel
blending  and evaporation.  For these treatment methods,
an efficiency of zero must be reported.

For metal  compounds, the reportable concentration  and
treatment  efficiency must be  calculated based  on  the
weight of the parent metal  and not  the weight of the
metal compounds.  Metals are not  destroyed but can only
be physically  removed or chemically  converted from  one
form  into  another.   The treatment  efficiency reported
must  only represent  physical  removal  of the parent metal
from   the   wastestream,   not  the   percent  chemical
conversion  of the metal compound. If a listed treatment
method converts   but  does  not  remove  a metal  (e.g.,
chromium reduction), the method  must be  reported,  but
the treatment efficiency must be reported as zero.

All data available at your facility must be  utilized to
calculate  treatment  efficiency  and   influent  chemical
concentration.   You are not  required  to collect any  new
data for  the purposes  of  this reporting requirement.  If
data  are lacking, estimates  must  be made  using  best
engineering judgment or other methods.

  F.  Based  on Operating Data?

This column requires you to indicate "Yes"  or "No" to
whether  the treatment  efficiency  estimate  is based  on
actual operating  data.   For example, you  would check
"Yes" if the estimate is based on monitoring of influent
and  effluent  wastes under typical operating  conditions.
If the efficiency estimate  is based on  published data for
similar processes or on equipment  supplier's literature, or
if you otherwise estimated either the  influent or effluent
waste comparison or the flow rate, you  must check "No."

8. Optional Information on Waste
    Minimization

Information provided in Part  III,  Section 8, of the form
is optional.   This section allows  you to identify waste
minimization efforts relating to the reported toxic
chemical that may  not have been reflected in your
responses to previous sections of the form.

A. Type  of modification

Enter  one  code  from   the  following   list   that  best
describes the type of waste minimization activity:

       Ml  - Recycling/reuse on-site.
       M2  - Recycling/reuse off-site.
       MS  - Equipment/technology modifications.
       M4  - Process procedure modifications.
       M5  - Reformulation/redesign of product.
       M6  - Substitution of raw materials.
       M7  - Improved housekeeping  training, inventory
              control.
       MS  - Other waste minimization technique.
                                                       B-17

-------
  B.  Quantity of the chemical in the
      wasiestream prior to treatment/
      disposal

Enter the pounds  of the toxic chemical in wastes in the
reporting year and  the pounds in  wastes in the year prior
to  implementing waste  minimization (the "base  year").
Alternatively, to protect  confidential information, you may
wish to enter only  the percentage by which the weight of
the chemical  in  the  wastes  has changed.   This  figure
(percentage)  may   be  calculated  using  the  following
formula:
toxic chemical in wastes in reporting year -
  toxic chemical in wastes in prior year
  toxic chemical in wastes in prior year.
xlOO
The resulting figure may be either negative or positive.

  C.  Index

Enter the ratio of reporting-year production to production
in the base year.  This index should be calculated to most
closely reflect activities involving the chemical.  Examples
of acceptable indices include:
  - Chemical produced in 1987/chemical produced in 1986.
  - Paint produced in 1987/paint produced in 1986.
  - Appliances coated in 1987/appliances coated in 1986.
  - Square feet  of solar collector fabricated  in
    1987/square feet of solar collector fabricated in 1986.
  - Value of sales in  1987/value of sales in 1986.

For example, a company manufactures 200,000 pounds of
a  chemical  in 1986 and  250,000  pounds  of the same
chemical in  1987.   The index  figure to report would be
1.3 (1.26 rounded).  The index  provides a means for users
of the  data  to distinguish the  effects  of  changes in
business  activity from  the effects specifically  of waste
minimization  efforts.  It  is  not necessary to indicate the
units on which the index is based.

  D.  Reason for action

Finally, enter the  codes from the following  list that best
describe  the  reason  for initiating the waste minimization
effort:

       Rl - Regulatory requirement for the waste.
       R2 - Reduction of treatment/disposal costs.
       R3 - Other process cost reduction.
       R4 - Self-initiated program.
       R5 - Other (e.g., discontinuation of product,
           occupational safety, etc.).

    •  A hazard summary.
    •  A brief description of the chemical.
    •  Workplace exposure limits.
    •  Acute and chronic health effects.
    •  Medical testing.
    •  Definitions of terms.

    It is important to note, however, that these fact sheets  contain
occupational data based on a healthy male worker population.   Therefore,  the
information presented (such as workplace exposure limits) do  not  reflect
environmental exposures and may not be protective of the  general  human
population (which includes women, children, and sensitive populations).

        A MESSAGE FROM THE ENVIRONMENTAL PROTECTION AGENCY

    The Emergency Planning arid Community Right To Know Act of
 1986 requires the Environmental Protection Agency to establish
 the Toxic Release Inventory, a national data base containing
 information on the release of 328 toxic chemicals from
 manufacturing plants  in the United States.   This Fact Sheet,
 prepared by the New Jersey Department of Health, concerns one of
 these chemicals.  EPA is distributing copies of this Fact Sheet
 in order to .help the  public understand the potential health
 effects of exposure to chemical releases identified in the Toxic
 Release Inventory.

    Readers should be aware that determining the health effects
 of chemicals is a very complex process.   These Fact Sheets are
 summaries of facts about the chemicals.   In addition,  there may
 be subtle but important differences in the ways in which the
 State of New Jersey,  EPA, and other scientific institutions might
 state their conclusions regarding the health effects of
 particular chemicals  according to potential exposures.  However,
 we believe these New  Jersey Fact Sheets are very useful sources
 of summary information.

    Since New Jersey  wrote these Fact Sheets for workers wha may
 be exposed to the chemicals where they work, several sections of
 the Fact Sheets are about workplace, rather than community
 situations.   Levels of exposure at work—such as in factories or
 repair shops—are often much higher than community exposures.  In
 addition, the ways  that community residents are exposed may also
 be different.   For  example, workers may be  exposed to a
particular  chemical by air and skin contact, but residents may be
 exposed to  the same chemical through their  drinking water.

    Finally, readers  should note most chemicals have not been
tested for  toxicity in a comprehensive manner.  There are
scientific  gaps in  our knowledge about the  health effects of most
chemicals.   These Fact Sheets can only provide information on
health effects where  testing for ^toxicity has actually been done
or where comparisons  with similar chemicals can be drawn.   As
 further scientific  knowledge is acquired, additional information
will be made available.

HAZARD SUMMARY
* Ethylene  Oxide   can  affect  you  when
  breathed in.
* Ethylene Oxide is a  CARCINOGEN--HANDLE
  WITH EXTREME  CAUTION.
* It may damage the developing fetus.
* Contact  with liquid can  cause  severe
  burns and frostbite.
* The vapor may cause headaches,  nausea,
  vomiting,   diarrhea,   difficulty   in
  breathing,   drowsiness,  weakness,   and
  loss  of muscle  control.  Higher  expo-
  sures may cause a build-up of fluid in
  the lungs (pulmonary edema).   This can
  cause death.
* It is a HIGHLY FLAMMABLE LIQUID/GAS and
  a DANGEROUS FIRE  and EXPLOSION HAZARD.

IDENTIFICATION
Ethylene Oxide  is normally a  colorless gas
or liquid.   It  has  an  ether-like odor and
is used to make antifreeze, polyesters,
laundry detergents  and as  an  industrial
sterilant.

REASON FOR CITATION
* Ethylene Oxide is on the Hazardous Sub-
  stance List  because it is regulated by
  OSHA  and cited by  NIOSH,  ACGIH,  IARC
  and NFPA.
* This  chemical is on the Special Health
  Hazard  Substance- List because it  is  a
  CARCINOGEN, a MUTAGEN, and is REACTIVE.
* Definitions are attached.

HOW  TO DETERMINE IF YOU ARE  BEING
EXPOSED
* Exposure to  hazardous substances should
  be  routinely  evaluated.   This  may in-
  clude  collecting  air  samples.    Under
  OSHA  1910.20, you have a legal right to
  obtain copies of sampling results from
  your  employer.   If you think you are
  experiencing   any work-related  health
  problems, see a doctor trained  to rec-
  ognize  occupational  diseases.     Take
  this Fact Sheet with you.

                          * ODOR THRESHOLD - 430 ppm.
                          * This odor  threshold  is  well above the
                            exposure limits and should not be con-
                            sidered as a warning of exposure.

                          WORKPLACE EXPOSURE LIMITS
                          OSHA:    The  legal  airborne   permissible
                                  exposure limit  (PEL) is 1 ppm av-
                                  eraged over an 8-hour workshift.
                          NIOSH:   The recommended airborne exposure
                                  limit is less than 0.1 ppm aver-
                                  aged over an 8-hour workshift and
                                  5 ppm, not  to be  excee'ded during
                                  any 10 minute work period in any
                                 ^single day.
                          ACGIH:   The recommended airborne exposure
                                  limit is  1 ppm averaged over  an
                                  8-hour workshift.

                          * Ethylene Oxide is a PROBABLE CARCINOGEN
                            in humans.  There  may be no safe level
                            of  exposure to  a carcinogen, so  all
                            contact should be reduced to the lowest
                            possible level.

                          WAYS  OF REDUCING EXPOSURE
                          * A regulated, marked area should be es-
                            tablished where Ethylene Oxide is han-
                            dled,  used,  or  stored  as  required  by
                            the OSHA standard 1910.1047.
                          * Wear   protective   work  clothing  when
                            working with the liquid.
                          * Wash thoroughly immediately  after expo-
                            sure to  Ethylene  Oxide  and  at the end
                            of the workshift.
                          * Post hazard and  warning information in
                            the work area.  In addition, as part of
                            an  ongoing  education and  training ef-
                            fort,  communicate all   information  on
                            the health  and safety hazards of Ethy-
                            lene   Oxide  to   potentially  exposed
                            workers.

ETHYLENE OXIDE

This Fact Sheet is a-summary source of in-
formation of all potential and most severe
health hazards that may  result  from expo-
sure.  Duration of exposure, concentration
of  the  substance and  other factors  will
affect your  susceptibility to any  of  the
potential effects described below.
HEALTH HAZARD INFORMATION

Acute Health  Effects
.The  following  acute  (short-term)  health
effects may  occur immediately or  shortly
after exposure to Ethylene Oxide:

*  Exposure  to  Ethylene  Oxide  may  cause
   headaches,  nausea,  vomiting,  diarrhea,
   difficulty   in  breathing,   drowsiness,
   weakness,  and  loss  of muscle  control.
   Higher  exposures may cause passing  out
   and even death.
*  Ethylene  Oxide  vapor can  irritate  the
   eyes, nose  and throat,  and may irritate
   the  lungs,   causing   coughing   and/or
   shortness  of breath.    Higher  exposures
   can cause  a build-up  of  fluid  in  the
   lungs   (pulmonary   edema).     This  can
   cause death.
*  Numbing of the  sense of smell  can  oc-
   cur, making exposure  harder to detect.
*  Contact with  the  undiluted liquid  can
   cause frostbite.
*  Contact with  solutions of  Ethylene  Ox-
   ide in water  can cause skin burns with
   blistering  and  redness.    Skin  ulcers
   may be  delayed, often appearing  1 to 5
   hours after contact.

Chronic  Health Effects
The  following chronic  (long-term)  health
effects can occur at some time after expo-
sure  to  Ethylene Oxide  and  can last  for
months or years:

Cancer Hazard
*  Ethylene Oxide is a PROBABLE  CARCINOGEN
   in humans.   There is  some  evidence that
   it causes leukemia  in humans, and it  has
   been  shown   to   cause  leukemia   and
   abdominal cavity cancer in animals.
*  Many scientists believe  that  there  is
   no  safe   level  of   exposure   to   a
   carcinogen.

Reproductive  Hazard
*  It may  damage  the developing fetus.
                              page 2 of 5

*  There is an  increased  incidence  of  gy-
   necological   disorders  and  spontaneous
   abortions  among workers in Ethylene  Ox-
   ide  production.   Its  role in  this  in-
   crease is  unclear  at this  time.

Other  Long-Term Effects
*  Ethylene Oxide  may damage the nervous
   system,   causing  numbness,   "pins  and
   needles",  and/or weakness in  the  hands
   and  feet.
*  It may damage the  liver and kidneys.
*  It may cause a skin allergy.   If an  al-
   lergy develops, very  low future  expo-
   sures  can  cause   itching  and a  skin
   rash.

MEDICAL

Medical Testing
For  those  with  frequent or  potentially
high exposure  (half  the  TLV or  greater),
the  following  are recommended  before  be-
ginning work  and at regular times  after
that:
*  Lung function tests.

If  symptoms  develop  or  overexposure  is
suspected, the  following may be useful:
*  Consider chest x-ray after  acute over-
   exposure .
*  Evaluation  by  a   qualified  allergist,
   including careful  exposure history  and
   special testing,  may help diagnose skin
   allergy.
*  Liver and kidney function  tests.

Any  evaluation  should  include   a careful
history of past and  present symptoms with
an exam.   Medical tests that look for dam-
age  already  done are not  a substitute  for
controlling exposure.

Request copies  of  your  medical  testing.
You  have a legal  right to this information
under OSHA 1910.20.

Mixed  Exposures
Because smoking can  cause  heart disease,
as  well  as  lung cancer, emphysema,  and
other  respiratory problems,  it  may worsen
respiratory  conditions caused by chemical
exposure.   Even if you have smoked  for  a
long time, stopping  now  will reduce your
.risk of developing health problems.

WORKPLACE CONTROLS  AND PRACTICES

Unless a  less  toxic chemical can be  sub-
stituted for a  hazardous  substance,  ENGI-
NEERING  CONTROLS  are  the most  effective
way of  reducing exposure.  The  best  pro-
tection  is to  enclose operations  and/or
provide  local  exhaust  ventilation at  the
site of chemical release.   Isolating oper-
ations  can also  reduce  exposure.    Using
respirators  or  protective  equipment  is
less effective than the controls mentioned
above, but is sometimes necessary.

In evaluating the controls present in your
workplace, consider: (1) how hazardous the
substance  is,   (2)  how much  of the  sub-
stance is  released  into  the  workplace and
(3) whether  harmful skin or eye  contact
could occur.   Special controls  should be
in  place  for  highly  toxic  chemicals  or
when  significant  skin, eye,  or  breathing
exposures are possible.

In  addition,  the  following controls  are
recommended:

*  Where possible,  automatically pump liq-
   uid Ethylene Oxide  from drums  or  other
   storage  containers  to  process  contain-
   ers.
*  Specific engineering  controls are  re-
   quired by OSHA and recommended for this
   chemical by  NIOSH.  Refer to  the  NIOSH
   criteria document:  Occupational  Expo-
   sure  to Ethylene Oxide #77-200 and the
   OSHA  standard'1910.1047.
*  Before entering a confined space  where
   Ethylene Oxide  may be present,  check to
   make  sure that an  explosive  concentra-
   tion  does not exist.

Good  WORK PRACTICES  can help  to  reduce
hazardous  exposures.   The  following  work
practices are recommended:

*  Workers  whose clothing  has been contam-
   inated  by   the  liquid  should  remove
   clothing promptly  and  allow  Ethylene
   Oxide  to evaporate.
*  If  there is  the possibility of skin ex-
   posure,   emergency   shower   facilities
   should be provided.
*  On  skin  contact with liquid,  immediate-
   ly  wash  with  warm water.   At  the  end of
   the workshift,  wash any  areas  of  the
   body  that  may  have had  contact  with
                              page 3 of 5
   Ethylene  Oxide in  solution,  whether or
   not known skin contact has occurred.
*  Do not eat,  smoke,  or drink where Ethy-
   lene  Oxide  is handled,  processed,  or
   stored, since  the chemical  can be swal-
   lowed.     Wash hands  carefully  before
   eating or smoking.

PERSONAL PROTECTIVE EQUIPMENT

WORKPLACE CONTROLS  ARE  BETTER THAN  PER-
SONAL PROTECTIVE EQUIPMENT. However,  for
some jobs (such  as  outside  work,  confined
space entry,  jobs  done  only  once  in  a
while,  or jobs done  while  workplace  con-
trols are being  installed),  personal  pro-
tective equipment may be appropriate.

The  following  recommendations  are  only
guidelines and may not apply to every sit-
uation .

Clothing
*  Avoid  skin contact with Ethylene  Oxide.
   Wear   protective  gloves  and  clothing.
   Safety equipment   suppliers/manufactur-
   ers can provide  recommendations  on the
   most protective glove/clothing material
   for your  operation.
*  All protective clothing (suits, gloves,
   footwear,  headgear)  should  be  clean,
   available each day,  and put  on  before
   work.
*  ACGIH  recommends  Chlorinated Polyethyl-
   ene as a  protective material.

Eye Protection
*  Eye protection is  included  in  the  rec-
   ommended  respiratory protection.

Respiratory  Protection
IMPROPER USE OF  RESPIRATORS IS DANGEROUS.
Such equipment should only  be  used  if the
employer has a written program that takes
into  account  workplace  conditions,   re-
quirements for worker training, respirator
fit  testing  and medical   exams,  as  de-
scribed in OSHA 1910.134.

*  At any exposure level,  use  a MSHA/NIOSH
   approved  supplied-air  respirator  with  a
   full facepiece operated in  the positive
   pressure  mode  or  with  a full facepiece,
   hood,  or  helmet in the  continuous  flow
   mode,   or use a  MSHA/NIOSH  approved
   self-contained breathing apparatus with
                                           D-5

-------
ETHYLENE OXIDE

  a  full facepiece operated  in pressure-
  demand or other positive pressure mode.
* Exposure  to  8,000  ppm is  immediately
  dangerous  to life  and  health.    If  the
  possibility  of  exposures  above  8,000
  ppm  exists,  use  a  MSHA/NIOSH  approved
  self-contained breathing  apparatus  with
  a  full facepiece  operated in continuous
  flow or other positive  pressure mode.

HANDLING AND STORAGE

* Prior  to  working  with Ethylene  Oxide
  you  should  be  trained on its  proper
  handling and storage.
* A  regulated, marked area should  be  es-
  tablished  where  Ethylene Oxide  is  han-
  dled,  used,  or stored.
* It must be stored to avoid contact with
  even  small  amounts of  ACIDS (such  as
  NITRIC  or  SULFURIC   ACIDS);   ALKALIS
  (such  as  SODIUM HYDROXIDE  or POTASSIUM
  HYDROXIDE);  CATALYTIC  ANHYDROUS  CHLO-
  RIDES  of IRON, ALUMINUM or  TIN;  IRON or
  ALUMINUM OXIDE;  or  METALLIC  POTASSIUM,
  since  it  may react  by  itself,  liberat-
  ing  much_ heat  and  causing a  possible
  explosion.
* Ethylene Oxide  should  not  contact  OXI-
  DIZERS (such  as  PERCHLORATES,   PEROX-
  IDES,  PERMANGANATES,  CHLORATES,  and NI-
  TRATES) since an explosion  could occur.
* Store  in tightly  closed containers  in a
  cool   well-ventilated  area  away  from
  HEAT,  SPARKS, or SUNLIGHT.
* Sources of ignition such as smoking and
  open  flames  are prohibited where Ethy-
  lene Oxide is handled,  used, or stored.
* Metal  containers  involving  the transfer
  of 5  gallons or more of  Ethylene Oxide
  should be  grounded  and bonded.    Drums
  must   be  equipped   with   self-closing
  valves,  pressure  vacuum  bungs,   and
  flame  arresters.
* Use only  non-sparking  tools  and equip-
  ment,  especially  when opening and clos-
  ing containers of Ethylene  Oxide.
* Wherever  Ethylene  Oxide  is used,  han-
  dled,   manufactured,  or   stored,   use
  explosion-proof   electrical   equipment
  and fittings.

QUESTIONS AND ANSWERS
Q:  If I have acute health effects, will I
    later get chronic health effects?
A:  Not always.   Most chronic (long-term)
    effects result from repeated exposures
    to a chemical.

Q:  Can  I  get  long-term effects  without
    ever having short-term effects?
A:  Yes, because long-term effects can oc-
    cur from repeated exposures to a chem-
    ical at levels not high enough to make
    you immediately sick.

Q:  What are  my  chances  of  getting  sick
    when I have been exposed to chemicals?
A:  The  likelihood  of becoming  sick  from
    chemicals  is  increased  as  the amount
    of exposure increases.  This is deter-
    mined by  the length  of time  and  the
    amount of material to which someone is
    exposed.

Q:  Don't all chemicals cause cancer?
A:  No.    Most chemicals  tested  by scien-
    tists are not cancer-causing.

Q:  Should I  be  concerned  if a chemical
    causes cancer in animals?
A:  Yes.  Most  scientists  agree  that  a
    chemical that causes cancer in animals
    should be treated as a suspected human
    carcinogen unless proven otherwise.

Q:  But don't they test animals using much
    higher levels of  a chemical  than peo-
    ple usually are exposed  to?
A:  Yes.   That's so  effects can  be  seen
    more clearly using fewer animals.   But
    high  doses alone  don't  cause cancer
    unless it's a cancer  agent.   In fact,
    a chemical  that  causes  cancer in ani-
    mals at high  doses could cause cancer
    in humans exposed to low doses.

Q:  Who  is at the greatest  risk from  re-
    productive hazards?
A:  Pregnant  women  are  at   greatest  risk
    from chemicals  that  harm the develop-
    ing fetus.  However, chemicals may af-
    fect the  ability  to  have children,  so
    both men and women of childbearing age
    are at high risk.

     FIRE HAZARDS
     *  Ethylene  Oxide  is  an  extremely  FLAM-
       MABLE GAS  or  LIQUID.    The gas  easily
       forms explosive mixtures with air.
     *  Fight a  fire  from  an  explosion-resis-
       tant  location.   Use dry chemical,  COj,
       water spray, or foam extinguishers.
     *  POISONOUS GAS IS PRODUCED IN FIRE.
     *  CONTAINERS  MAY EXPLODE IN FIRE.
     *  The vapor  or  gas  is  heavier  than air
       and may  travel  a  distance  to cause  a
       fire  or explosion  far from the source.
     *  If employees   are  expected  to   fight
       fires,   they   must  be   trained  and
       equipped as stated in OSHA 1910.156.

     SPILLS AND EMERGENCIES
     If  Ethylene  Oxide is spilled or  leaked,
     take the following steps:
     *  Restrict persons not wearing protective
       equipment  from area of spill or  leak
       until clean-up is  complete.
     *  Remove all  ignition sources.
     *  Ventilate area of  spill or leak.
     *  If in the  gaseous form,  stop the  flow
       of gas.   If the source of  the  leak is  a
       cylinder and the leak cannot be  stopped
       in place,   remove  the  leaking  cylinder
       to a  safe place in the open air and re-
       pair  the  leak or  allow the  cylinder to
       empty.
     *  Keep  Ethylene  Oxide out  of a  confined
     .  space,  such as  a 'sewer,  because  of the
       possibility of  an  explosion, unless the
       sewer is designed  to prevent the  build-

                           APPENDIX B - FEDERAL LANS
CLEAN AIR ACT (CAA)
(Office of Air Quality Planning and Standards)

    The Clean Air Act was enacted into law in 1970 and amended in 1974, 1977,
and 1981.  The 1970 amendments set emissions standards for automobiles and
required EPA to set and periodically review three different types of national
air standards.  The first are National Ambient Air Quality Standards
(NAAQSs).  The NAAQSs define the principal types of pollution and the levels
of each that should not be exceeded for the protection of human health and
welfare.  EPA formally adopted the first NAAQSs in 1971.  Once EPA sets a
NAAQS, State governments have the responsibility to determine how NAAQSs can
be met and maintained most efficiently at the local level.  The primary
mechanism States use to characterize local air quality and define strategies
to achieve national standards is the State Implementation Plan (SIP).  EPA is
responsible for the review, approval, and general oversight of all SIPs.

    In addition, EPA is required under this Act to define allowable New Source
Performance Standards (NSPSs) which establish allowable emissions limitations
for different kinds of stationary sources.  The regulations include general
criteria for preconstruction permit programs, and for new and modified
stationary sources of air emissions.  Again, while EPA was given the authority
to develop these regulations, Congress recognized that State governments are
best suited to issuing and enforcing permits.  EPA is also required to set
National Emissions Standards for Hazardous Air Pollutants (NESHAPs) for which
no ambient air quality standards exist.  Eight substances are currently listed
under NESHAPs:  arsenic, asbestos, benzene, beryllium, coke oven emissions,
mercury, radon-222, and vinyl chloride.  Facility emissions standards have
been established for all these substances (except coke oven emissions).  (U.S.
EPA, 1987b, pp.  1-2.)  Under Title II of the Act, EPA is required to prescribe
and manage programs to test and certify new motor vehicle engines for
compliance with national standards, and also to enforce provisions related to
in-use emissions from vehicles.
                                   E-l

-------
 CLEAN WATER  ACT  (CWA)
 (Office  of Water Regulations  and Standards)

    The  Clean Water  Act  was passed in 1972 and amended several times, most
 recently in  1987.  The Act  established a national goal of achieving fishable
 and swimmable waters wherever  attainable by 1983, and eliminating pollutant
 discharges into  the  Nation's  waterways by 1985.   The primary objective of the
 Act is *...to restore and maintain the chemical,  physical, and biological
 integrity of the Nation's waters."  Under the Clean Water Act, EPA established
 water quality criteria for the development of:

    •  Water quality standards.
    •  Technology-based  effluent  limitation guidelines.
    •  Pretreatment  standards.
    •  New source performance  standards.
    •  A national permit program  to regulate the  discharge of pollutants.

    The  CWA provides for the National Pollutant Discharge Elimination System
 (NPDES)  which incorporates and applies effluent limitations in individual
permits  for both municipal and direct industrial  dischargers.  Under these
permits, dischargers are subject  to both technology-based treatment
 requirements, and where  necessary  to protect a designated use, controls based
on water quality  standards.  States are responsible for  setting their own
water quality standards and developing water quality management programs.

    The  technology-based limitations prescribe minimum standards of
performance for municipal and  industrial dischargers without regard to the
quality  of receiving waters.   By contrast,  water  quality standards identify
intended uses of particular water  bodies,  and on  the basis of water quality
criteria guidance developed by EPA,  set the biological and chemical conditions
necessary to sustain those uses.

    The Act also establishes a program to identify those water bodies not
achieving water quality standards  because of toxic pollutants discharges.  The
                                      E-2

-------
states must assess and identify affected water bodies and by February 1989,
set specific effluent limitations for these discharges in NPDES permits.
These individual control strategies must assure water quality standards are
attained.  (U.S. EPA, 1987b, pp. 6-7.)
COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY ACT OP 1980
(CERCLA) AND THE SUPBRFUND AMENDMENTS AND REAUTHORIZATION ACT OF 1986 (SARA)
(Office of Emergency and Remedial Response)

    The Comprehensive Environmental Response, Compensation and Liability Act
(CERCLA or "Superfund") was enacted into law in 1980 when it became apparent
that the regulatory framework of RCRA (see below) was not adequate to cope
with the uncontrolled disposal of toxic chemicals.  CERCLA authorizes the
federal government to respond directly to releases or threatened releases of
hazardous substances, pollutants, or contaminants that may endanger the public
health, welfare, or the environment.  This legislation also established a $1.6
billion fund to cover the costs of cleaning up abandoned hazardous waste
chemical sites.

    The statute was amended in 1986.  Title I of the Superfund Amendments and
Reauthorization Act (SARA) contains provisions relating primarily to response
and liability.  Title II contains miscellaneous provisions.  Title III
contains the emergency planning and community right-to-know provisions.
Section 313, the Emissions Inventory, is part of Title III.  (U.S. EPA, 1987b,
p. 29.)
FEDERAL INSECTICIDE, FUNGICIDE, AND RODENTICIDE ACT (PIPRA)
(Office of Pesticide Programs)

    The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)  was passed
in 1947 and amended in 1972, 1975, and 1978.  It was administered by the
Department of Agriculture until 1970 when jurisdiction was transferred to the
EPA.  The purpose of the Act is to control the use of pesticides to  safeguard
                                     E-3

-------
 the health  of  the  public  and  to prevent adverse effects on the environment.
 Under  FIFRA, EPA is  authorized to:

    •  Register  pesticide products  on the basis of both safety and benefits,
       (This balancing  of risks and benefit underlies all basic regulatory
       decisions under  the Act.)
    •  Specify the terms  and  conditions of pesticide use prior to being
       marketed.
    •  Remove  unreasonably hazardous pesticides from the marketplace.  (U.S.
       EPA, 1987b, p. 15.)
MARINE PROTECTION, RESEARCH,  AND  SANCTUARIES ACT (MPRSA)
(Office of Marine and  Estuarine Protection)

    MPRSA was passed to protect the  marine  environment and public health from
the dumping of all materials  in ocean  waters.   Section 102(b)  of the law
states that it is the  policy  to "regulate the  dumping of all types of
materials into ocean waters and to prevent  or  strictly limit the dumping into
ocean waters of any material  which would adversely affect human health,
welfare, or amenities, or the marine environment,  ecological systems, or
economic potentialities."
NATIONAL ENVIRONMENTAL POLICY ACT  (NEPA)

    The National Environmental Policy Act  was  enacted into law in 1969.  NEPA
directs federal agencies to plan their policies  and  actions in light of the
environmental consequences.  Agencies must  prepare  an environmental impact
statement (BIS) for any major federal action that will significantly affect
the quality of the human environment.  EISs must identify and  discuss the
environmental effects of the proposed action and identify, analyze, and
compare options.  (U.S. EPA, 1987b, p. 39.)
                                      E-4

-------
RESOURCE  CONSERVATION AND RECOVERY ACT OF 1976 (RCRA) AND THE HAZARDOUS AND
SOLID WASTE  AMENDMENTS OF 1984 (HSWA)

    Congress passed  the Solid Waste Disposal Act in 1965.  This Act was the
first federal law  to require  safeguards and encourage environmentally sound
methods for  disposal of household, municipal, commercial, and industrial
refuse.   Congress  amended this law in  1970 by passing the Resource Recovery
Act and again in 1976 by passing the Resource Conservation and Recovery Act
(RCRA).   RCRA was  updated and amended  by the Hazardous and Solid Waste Act
(HSWA) of 1985.  The primary  goals of  RCRA are to:

    •  Protect human health and  the environment from the potential hazards of
       waste disposal.
    •  Conserve energy  and natural resources.
    •  Reduce  the  amount  of waste  generated,  including hazardous waste.
    •  Ensure  that wastes are managed  in an environmentally sound manner.

    In addition, the Act  is designed to promote the conservation of natural
resources  through  the recovery of  usable energy and materials.  RCRA
authorizes the EPA to regulate hazardous wastes from their generation to
disposal;  to  foster  the establishment  of regulatory programs in the states for
controlling  the disposal  of solid  wastes on land  and prohibiting the use of
open dumps;  and to assist in  developing national  conservation and recovery
policies.   (U.S. EPA, 1986i,  pp. 3-4.)
SAFE DRINKING WATER ACT  (SDWA)
(Office of Drinking Water)

    The Safe Drinking Water Act provides  for  the  safety of drinking water
supplies throughout the United States.  It  was  passed  in 1974 and amended in
1976, 1979, and 1986.  Under the Act,  EPA has the primary responsibility to:

    •  Establish National Primary Drinking  Water  Regulations (NPDWRs)  which
       govern public water supplies for the protection of public health.
                                      E-5

-------
    •  Establish National Secondary Drinking Water Regulations (NSDWRs)  which
       govern the taste, odor, and appearance of drinking water.

    •  Review and approve applications from the various states to assume
       primacy in the enforcement of those standards.   Implementation of the
       SDWA regulations rests primarily with the states.  A state must apply
       for primary enforcement status (primacy) which  requires that states
       have regulations at least as stringent as federal standards.

    •  Supervise public water supply systems and other sources of drinking
       water.

    The Act also includes provisions to control the underground injection of
water and other substances which might endanger drinking water sources.   EPA

implemented several programs for protecting ground water under the Act as
enacted in 1974.  One of these programs> the Underground Injection control
Program, regulates the injection of any fluid, including disposal of

industrial wastes in deep underground wells.  (U.S. EPA, 19875, p. 10.)
TOXIC SUBSTANCES CONTROL ACT (TSCA)
(Office of Toxic Subtances)


    The Toxic Substances Control Act was enacted into law in 1976.   TSCA gives

EPA broad regulatory authority over  chemical substances during all  phases of
their life cycle, from before their  manufacture to final disposal.   The Act

establishes a national effort to prevent unreasonable risk to human health and

the environment.  There are  three major TSCA activities:


    •  The premanufacture notification program.  This program provides  for
       scrutiny of health and environmental effects of new chemicals, so that
       their safety can be ensured before being released into the environment.

    •  Testing.  When EPA believes that a chemical may present an unreasonable
       risk to health of the environment, testing can be required under TSCA.
       To require testing, EPA must  find that there is insufficient data on
       the chemical substance and that further testing is necessary before a
       risk determination can be made.

    •  Control of existing chemicals.   EPA can take various regulatory
       measures to control existing  chemicals that pose an unreasonable risk
       to health or the environment.
                                     E-6

-------
    Under TSCA, EPA also compiles and periodically  amends  a  list  of  chemical
substances manufactured or processed for commerical purposes -  the TSCA
Chemical Inventory.  The Inventory contains approximately  63,000  chemical
substances.   (U.S. EPA, 1987, p. 19.)

   Notes :

     1.   Aquatic toxicity is given as the LC50/ or that concentration of the material dissolved in water in parts per million  or
          milligrams/liter (which is equivalent) that will kill 50% of the test organism population in 96 hours.  Some of the data
          are shown in a range of ppm, as cited in the following sources:

             Supplement to Development Document:  Hazardous Substances Regulations, Section 311 of the Federal Water  Pollution
             Control Act as Amended 1972, (EPA-440/9-75-009), November 1975.

             The Registry of Toxic Effects of Chemical Substances  (RTECS), U.S. Department of Health and Human Services, National
             Institute for Occupational Safety and Health, Publication No. 83-107, 1981-1982, and Publication No. 86-1036,  November
             1985 (supplement).

             Additional sources for determining aquatic toxicity are  listed in the Technical Background Document  to Support
             Rulemaking Pursuant to CERCLA Section 102, Volume  1,  March  1985.
          The test used to determine  the  toxicity value is LD,.. or  LD.    LDso is tna lethal dose  to 50% of  the  test  animal
          population  in milligrams per  kilogram of body weight.   LD1o  is the lowest dose in milligrams per kilogram of  body  weight
          known to have hat

     3.   Units are mg/kg.
known to have had a lethal effect on the test animal species.
I
>-•    4.   The test  used  to  determine  the  toxicity  value  is LC,Q or  LC^.  LC5Q  is tha lethal concentration  in  parts  per  million to
^°         50% of  the  test animal  population.   LC.   is  the lowest  concentration  in parts per million known to have  had  a  lethal
          effect  on the  test  animal species.

     5.   Units are parts per  million.

     6.   The chronic  toxicity RQ is  based on  the  composite  score.   The  composite score is the product of the  dose ratirrg value and
          the effect  rating value.    The  dose  rating value may  range from 1  to  10, depending on  toxicity, with 10  being  most toxic.
          Similarly,  the type  of  effect  is given  an effect rating value  from 1  to 10, with 10 being most  severe.   A composite score
          is then determined  by multiplying the RVd by the RVe, with a possible range of  1 to 100.  Thus, the  highest  scores are
          most toxic.  An "I.D."  is assigned when  insufficient  data are  available to make an assessment.  An  "*"  is  assigned when
          the substance  is  known  to have  a chronic effect, but  the  RQ has already been  set at the  1-pound level  on the basis of
          some other  criterion, and no  further evaluation was  made.

     7.   Part of the  methodology used  to adjust  the statutory  RQs  of potential carcinogens evaluates  the strength of  the evidence
          that a  substance  causes cancer.  Each potential carcinogen is  assigned to one of the following  weight-of-evidence
          categories,  which,  along with the potency factor,  determines the  potential carcinogenicity  RQ  for the  substance:

          Group A-—Human Carcinogen —  An agent  is placed in this group  only when there is  "sufficient*  evidence from  epideaiologic
          studies to  support  a causal association between exposure  to the agent(s) and  cancer.
                                                               10

          Group B—Probable Human Carcinogen — This group includes  agents for which the weight-of-evidence of human
          carcinogenicity based on epidemiologic studies is "limited" and also includes  agents for which the weight-of-evidence of
          carcinogenicity based on animal studies is "sufficient." The group is divided  into two groups.  Group Bl is usually
          reserved for agents for which there is "limited" evidence  of carcinogenicity from epideniologic studies.  It is
          reasonable, for practical purposes, to regard an agent  for which there is "sufficient* evidence of carcinogenicity in
          animals as if it presented a carcinogenic risk to humans.   Therefore, agents for which there is "sufficient" evidence
          from animal studies and for which there is "inadequate" evidence or "no data"  from epidemiologic studies (human) would
          usually be categorized under Group B2.

          Group C—Possible Human Carcinogen — This group is used  for agents with "limited" evidence of carcinogenicity in animals
          in the absence of human data.  It includes a wide variety  of evidence, for example: (a) a malignant tumor response in a

   This list only includes entries for those toxic substances/hazardous substances for which data are available to derive an RQ on
   the basis of acute inhalation toxicity.

   Specific xylene and cresol isomers which are toxic substances  are not specifically listed as CERCLA hazardous substances, and
   are therefore not listed here.  However, data on the specific  isomers of xylene and cresol were used to derive the RQs for mixed
   xylenes and cresols which are specifically listed as CERCLA hazardous substances.  These aixed isomers of xylene are listed in
   the table as "xylene (mixed).*

                       RISKS OF ENVIRONMENTAL POLLUTANTS
Chemical Scoring, System for Hazard and Exposure Assessment (CSSHEA)

    CSSHEA is a qualitative ranking system used by the EPA Office of Toxic
Substances (OTS) to screen and prioritize chemicals for further assessment.
It is a first-cut, rapid way of evaluating a large number of chemicals to
assist in focusing resources at later stages of assessment.  CSSHEA
incorporates both hazard and exposure potential.

    For each chemical, scientists with relevant expertise separately score
eleven exposure and hazard parameters on a scale of 0 to 9.  Each parameter is
scored independently by two professionals who resolve differences if scores
differ by more than one point.  To score, the scientists review a source
document, such as an EPA Health and Environmental Effects Profile, that
summarizes the relevant human, animal, genotoxic, and environmental data on
the chemical.  Scorers use objective criteria to assign a numerical score when
data are available, or analog/structure-activity relationships in the absence
of data.  Scorers may raise or lower a score based on professional judgment,
and must provide a rationale for each assigned score.

    Scoring is performed on all or any combination of the eleven parameters.
The scores are not added,  weighted, or combined.  They are simply provided as
a.i overall hazard "profile."  At OTS, any chemical with at least one hazard
parameter and one exposure parameter of 8 or 9 is assigned a high priority for
further assessment.  Scored chemicals can be used as benchmarks against which
to compare the exposure and hazard potential of newly scored chemicals.

    Input Data;   The system relies on the availability of a major source
    document  (such as a HEEP)  that reviews and summarizes the relevant
    literature for the chemical.  In addition, information on chemical analogs
    and structure-activity relationships may be required.  Data from these
    sources are evaluated and  scored in the following areas:   (1) toxicity
    parameters;   carcinogenicity,  genotoxicity, developmental toxicity, acute
    and chronic mammalian toxicity, and aquatic toxicity; (2) exposure
    parameters;   bioconcentration, chemical production volume, occupational
    exposure, consumer exposure, environmental fate, and environmental
    exposure.  Currently,  HEEPs, CHIPS and OTS submissions are used as the
    basis for scores.   Each chemical takes approximately one month to score.

                                     G-2

-------
   Output;  Quantitative scores on a scale of 0 to  9 for up to eleven hazard
   and exposure parameters.

   The main obstacle to using this system for Section 313 data evaluation is
.hat a source document (that reviews and summarizes the Literature) is
issential to scoring.  Only a small portion of the Section 313 chemicals have
ieen scored by OTS.  The "Environmental Exposure" parameter is based largely
m the amount released to the environment; the current scoring criteria for
his parameter would have to be modified, since they  are based on total
estimated nationwide emissions, not on emissions from a single facility.

                 THE GRAPHICAL EXPOSURE MODELING SYSTEM (GEMS)
    The EPA Office of Toxic Substances developed the Graphical Exposure
Modeling System (GEMS) as an interactive information management tool designed
to assist in a quick and meaningful analysis of environmental problems.  GEMS,
as an operating environment, ties together several previously discrete tools
into a coordinated system that allows for multiple types of analyses. These
tools include environmental fate and transport models, chemical property
estimation techniques, statistical analysis, and graphical and mapping
programs.  These discrete systems are handled under a common environment and
the user interacts with the computer through an interface consisting of a
uniform set of menu screens which eliminate the usual requirements to learn
specific application languages.  Under development since 1981, GEMS has
several uses:

    •  Environmental Fate and Transport Modeling.
    •  Chemical Property Estimation.
    •  Data Management.
    •  Graphics.
    •  Geographic  Data Analysis and Mapping.
    •  Statistical Analysis.

    GEMS has many  features that make the system easy to access and operate:

    •  Accessed by telephone from virtually anywhere in the U.S.
    •  Supports a  variety of terminals.
    •  Supports SAS and Tektronics graphics.
    •  Includes a  sophisticated modeling system for ease of data input and
       analysis of output results for environmental simulation models.
    •  Provides geographic data analysis and mapping capabilities.
    •  Includes a  powerful file management capability along with many on-line
       databases that support routine use of the models.
                                    G-5

-------
     •  Requires no previous  knowledge of computer programming to operate the
       system.

     •  Complemented by a microcomputer version  (PCGEMS).
    BASIC STRUCTURE OP GEMS


    GEMS resides on the VAX Cluster at the USEPA National Computer Center at

Research Triangle Park, NC.  Originally developed on a VAX 11/780, GEMS

currently runs on MicroVAX II and VAX 8600 computers.  GEMS is designed under

a unique concept which integrates the computerized tools of graphics, mapping,

statistics, file management, and special functions such as modeling and

chemical property estimation under a user oriented and simple-to-learn

interface.  The system has three basic structural components.


    •  Data Management  The GEMS File Management Facility allows for the
       creation and manipulation of GEMS datasets.  It is designed to handle
       data in a variety of data formats and provides the user with a common
       interface for all data accessed.  This operation also allows the user
       to import data from outside of GEMS for use with GEMS procedures.

    •  Analytical and Mapping Tools  The modeling operation in GEMS
       allows users to simulate chemical behavior in various environmental
       media.  The GEMS interface allows users to build input data via
       standard prompts and menus and to store model output results in a
       standard format which then may be used with the statistics and graphics
       operations of GEMS.  The statistics and graphics operations provide
       data analysis by use of SAS and IMSL routines and functions.  Mapping
       ofindustrial facilities, rivers, population distributions, and modeled
       results is supported by SAS and Tektronics routines.

    •  User-Friendly interface  Users respond to menus and prompts produced by
       the system's user interface. Responses to system prompts are in plain
       English and extensive 'help* information is widely available.
    THE GENS DATA BASES


    The GEMS data base supports most types of environmental data useful for

exposure assessments of toxic substances.  One of the features that makes GEMS

so powerful is the ready availability of data for use with the models and

mapping procedures. These datasets  include:
                                      G-6

-------
    •  Industrial Facility Discharge Data (EPA NPDES Permitted Facilities).
    •  Meteorological Data (392 STAR Stations and 13000 State Climatic
       Divisions).
    •  Chemical Property Data.
    •  Water Supply Data (WSDB and PROS).
    •  Groundwater Data for Selected U.S. Cities.
    •  Stream Flow and Reach Data (USGS & EPA).
    •  Economic Census Data.
    •  Zip Code Location Data.
    •  Census Population Data for 1980 and 1983.
    •  Soil Textural Data (USDA-SCS).
    •  Geoecology County-level Environmental Characteristics Data.

    Descriptions of each data set are provided in the GEMS User's Guide.   The
user also has the capability of importing and installing external files as
part of the User Owned Data Sets which then may be used with GEMS.
    AHALYTICAL CAPABILITIES OF GEMS

    The use of GEMS and a description of its analytical capabilities are
described in the GEMS User's Guide.  The system has several operations for
analysis of environmental data:

    •  Modeling in Atmospheric,  Aquatic, and Soil Environments.
    •  Chemical Property Estimation.
    •  Data Management.
    •  Graphics, Mapping, and Geographic Data Analysis.
    •  Statistical Analysis.

    The brief discussion of a modeling analysis may best provide the reader
with a sense of the integrated nature of GEMS.  For our purposes let us assume
                                     G-7

-------
 that a user has data quantifying the mass of a carcinogenic chemical released
 annually from a stack.  With the assumption of no threshold for carcinogens,
 an annual total emission is adequate for exposure and risk calculations.
 Stack parameters are needed to characterize the release for an adequate
 estimation of exposure.

    The user selects the Industrial Source Complex Long Term Model (ISCLT)
 under the Modeling Option and  specifies the geographic coordinates of the
 facility.  A zipcode centroid is used if nothing else is available.  When the
 user specifies the facility location, a meteorological data base is searched
 and the names and distances to several meteorological reporting stations are
 returned for selection of the data to be used.  The joint frequency data and
 supplemental files are automatically inserted into the ISCLT model input file
 in the correct format.  The user then enters the release information, selects
 either 1980 or 1983 estimated census population data, and runs the model.

    Population data are automatically extracted from the Census Population
 database and combined with the model estimated concentrations to estimate the
 number of people exposed to various levels.  A post-processor for the model
 also estimates number of people at various levels of risk, if a potency slope
 factor is available for the chemical.

    Graphical routines lend support to this analysis.  The STAR Rose routine
generates wind roses and allows examination of the meteorological data in
 summary tabular form.   An isopleth mapping routine plots chemical
 concentration over population density for a qualitative description of
population exposure.
    NAPPING CAPABILITIES OP GBMS

    GEMS has the capability of producing maps at various spatial scales.   Maps
of study areas depicting state and county boundaries may be produced using
high resolution graphics terminals.  Any data set in GEMS which contains
geographic identification information may be used to generate overlays.
                                      G-8

-------
Chocopleth mapping is also supported.  Examples of information that can be
plotted on maps include:

    •  River Reaches from the EPA Reach File.
    •  Wastewater Treatment Facilities.
    •  Meteorological Stations.
    •  Dischargers of Industrial Wastes.
    •  Choropleths Depicting Levels of Use of Pesticides by County.


    USER INTERFACE

    GEMS comes with two basic types of menus, navigational menus and parameter
editing menus.

    Navigational menus help the user navigate through GEMS.  They present a
list of options from which to select.  After selecting one the user will
proceed to either another navigational menu or to a parameter editing menu.

    Parameter editing menus assist with data entry and creation of input files
for subsequent analyses.  The user simply enters the desired parameter value
into the field provided and the files will be created with the proper
structure and format.
    ACCESSING GEMS

    Employees of the USEPA wishing access to GEMS need only contact their
local ADP Coordinators to obtain and complete TSSMSS Form N258.  GEMS is also
available to members of other federal government agencies, state governments,
and private industry with billing handled through the National Technical
Information Service.  The NTIS contact person is Ms. Cathy Metzler
(703)487-4807.
                                     G-9

-------
    PCGENS
    In order to meet  the growing  demands  of  EPA modelers for access to the
features of GEMS, the Personal  Computer  (PC)  version  of  the Graphical Exposure
Modeling System (PCGEMS) has been  adapted from  the  VAX version.   PCGEMS has
many of the same features as GEMS  but  is  accessible at a local  level  on a  desk
top computer.  PCGEMS features  work  both  independently and  in concert with
their more powerful counterparts on  the mainframe.  PCGEMS  is designed to
reduce the reliance on the VAX  by  providing  the following independent
capabilities:

    •  Environmental  Fate and Transport Modeling.
    •  Chemical Property Estimation.
    •  File Management.
    •  Graphical Display of Modeled  Analyses.
    •  Mapping.
    •  Selected GEMS  Data Sets.

    In addition to its many stand-alone features, PCGEMS also works in concert
with GEMS on the EPA VAX Cluster.  This allows  much of the  task of  setting  up
modeling runs to be accomplished locally  with files uploaded  to the VAX for
execution of the model and downloading of files  to  the PC for subsequent
analysis.

    PCGEMS requires the following hardware:

    •  IBM XT/AT or compatible with  640 K RAM.
    •  Hard Disk and Floppy Drive.
    •  Graphics Board.
    •  DOS Version 2.2 or higher.
    •  8087 or  80287 Math Co-Processor.
    •  Minimum  of  10 Mb of available space on the hard disk;  less space may be
       required if the user installs only a few  features  of PCGEMS.
                                     G-10

-------
    While some specialized graphics and file manipulation routines have been
developed for PCGEMS, generalized graphics and database management procedures
have not been developed because there are many commercially available packages
that perform these functions on PCs.  The PCGEMS Utilities Function allows the
user to identify and set the path to the database management software,
graphics package, spreadsheet, etc. and to further customize PCGEMS with the
user's favorite programs.  Furthermore, PCGEMS contains some programs that
convert between PCGEMS, ASCII, dBASE, and LOTUS files thereby supporting dBASE
and LOTUS use with PCGEMS.

    PCGEMS is still under development; consequently, the distribution
mechanism has not yet been established.  Development of Release Version 1 of
PCGEMS is expected to be completed in the summer of 1988.  Information as to
its availability may be obtained at that time from the author (202) 382-3928.
    INPUT AND OUTPUT REQUIREMENTS

    Input Data;  On line computer data bases assist the assessor in
    characterizing the receiving environment.  Other input data are standard
    for the various environmental models.

    For instance, the ISCLT model requires the location of the emission
(latitude and longitude, Universal Transverse Mercator coordinates, or zip
codes); pollutant emission rate (grams per second); physical stack height
(meters); internal stack diameter (meters); stack gas exit velocity (meters
per second); and stack gas temperature (degrees Kelvin).  Optional data
include height and width of nearby buildings and distance from the stack to
the buildings.  If the emissions are classified as fugitive or non-point
emissions, then they should be modeled from area sources.  Data required
include the width of the area source and the height of release.  Stack
parameters, of course, are non existent for area sources.  Meteorological data
(Stability Array) are available from GEMS databases as are human population
data.  Optional data also include the cancer potency factor (mg/kg day)   or
the cancer unit risk factor (ug/m )~ .
                                     G-ll

-------
    If the PTPLU model is being used for a screening analysis, ambient air
temperature (degrees Kelvin) and mixing height (meters) data are required.
These data may be obtained from GEMS databases for the area of interest.
Stack parameters as described above are also required.

    The ReachScan model requires identification of the geographic area by USGS
Hydrologic Accounting Unit.  Within an accounting unit you can search by NPDBS
Number, Facility Name, SIC Code, Water Utility Name, or Reach Number.
Pollutant emission loading is specified in kg/day.

    Output;  The output of the ISCLT model includes the predicted maximum
    concentration; number of people estimated to be exposed at various
    concentration levels; number of people residing in the area specified;
    population exposure;  predicted concentration by distance and direction;
    maximum lifetime risk; and estimated annual number of cancer cases.  The
    output of the PTPLO model includes maximum concentration (grams per cubic
    meter) by distance for each atmospheric stability class.

    Output from the ReachScan model includes concentration in reaches with
drinking water intakes, identities of discharging facilities upstream of a
drinking water utility, and identities and locations of drinking water
utilities downstream from discharging facilities.

    The main obstacle to  using GEMS for Section 313 assessment is the absence
of information on TRI reporting form.  For example, stack parameters are not
requested for emissions to air and all releases are reported as annual totals.

 Hazard  Assessment  Model

     The Hazard Assessment Model was developed by EPA's Office of Toxic
 Substances  to help Local Emergency Planning Committees (LEPCs) assess the
 lethal  hazards related to potential airborne releases of hazardous substances,
 particularly the extremely hazardous substances listed under Section 302 of
 Title III of SARA.

     The analysis process is applied first with screening assumptions, and then
 with planning assumptions.  Reporting facilities may be screened using
 credible best or worst case assumptions.  The screening helps planners
 prioritize  facilities so that a more detailed hazard analysis can be conducted
 for  facilities that pose the greatest risk should a release occur.  These
 facilities  could then be visited to get more information and input data.
 After the initial screening, a reevaulation and adjustment of the quantity
 released and/or the rate of release of chemical can be made.  Reevaluation and
 adjustment  of variables—wind speed and air stability; selection of a higher
 level of concern—can also be performed.

     The analysis process consists of three basic hazard analysis steps:   (1)
 hazard  identification, (2) vulnerability zone estimation, and (3) risk
 analysis.  Hazard identification typically provides specific information on  -
 situations  that have the potential for causing injury to life or damage to
 property and the environment due to a hazardous materials spill or release.
 Vulnerability analysis identifies areas that may be affected or exposed;
 individuals who may be subject to injury or death from certain specific
 hazardous materials;  and what facilities, property, or environment may be
 susceptible to damage should a hazardous materials release occur.  Risk
analysis is a judgement of probability and severity of consequences based on
the history of previous incidents, local experience, and the best available
current  technological information.  A relative ranking of hazards combined
with site-specific  evaluations such as the vulnerability analysis will
complete much of  the  risk analysis process.
                                     G-14

-------
    Input Data;   The  initial  estimated screening zones are based on the
    following  assumptions:
    •  Rate of  release  to air:   Total  quantity of gases, powdered solids, or
       solids  in  solution are assumed  to  be  released in 10 minutes.  Liquids
       and molten solids are  released  instantaneously and evaporate.  The
       release  rate is  based  on  the  rate  of  evaporation.
    •  Topographic conditions:   Urban  or  rural setting.
    •  Meteorological conditions:  Wind speed =3.4 mph;
       Atmospheric stability  = F
    •  Level of Conern  (LOO: One-tenth of  the (NIOSH) published (IDLH) or
       one-tenth  of its approximation.  Pseudo IDLH = (1/10 LC$Q) or (1/100
             (oral or dermal) or (LCLQ) or  (LDLQ x 1/10)*
    Output;  The likelihood of a  hazard  occurrence  and the  severity of
    consequences are assessed as  high, medium,  or  low.  An  emergency response
    plan, required under Title III  of SARA,  can be  formulated based on the
    information gleaned through this process.

    The perceived complexity of this system  is  an  obstacle  to Section 313
assessment.  The numerical values used for Level of Concern and the
calculations that must be performed for  assessing  liquid releases  may be
perceived as difficult by some users.  Additionally,  this model has been
primarily used for assessing accidental  (generally,  short-term) releases of
extremely hazardous substances.  While some  of  the  Section  313 chemicals will
also be listed under Section 302, many of the Section 313 chemicals will be
much less toxic and will be released over a  longer  period of time.

Human Exposure Model

    The Human Exposure Model (HEM) produces quantitative expressions of public
exposure and carcinogenic risk to ambient air concentrations of pollutants
emitted from stationary sources.  Used by the EPA Office of Air Quality
Planning and Standards (OAQPS), HEM is a screening method that provides rough,
but not necessarily conservative, estimates of exposure and risk.

    The HEM contains 1) an atmosphere dispersion model (Gaussian); 2)
multiple-year meteorological data (STAR) at 314 airports across the U.S.;  and
3) a population distribution estimate based on 1980 U.S. Bureau of Census  data
(by block/group/enumeration of district).  Based on emission and stack
parameters and frequency of wind direction, wind speed, and atmospheric
stability classes, HEM estimates the magnitude and distribution of ambient air
concentations of the pollutant in the vicinity of the source.  The model is
programed to estimate these concentrations within a radial distance of 50
kilometers (30.8 miles) from the source.  If other radial distances are
preferred,  an override feature allows the user to select the distance desired.

    If the user wishes to use a dispersion model other than the one contained
in HEM,  HEM can accept the concentrations from the alternative model if they
are put  into the appropriate format.  Based upon the source location and the
radial distance specified, HEM combines numerically the distribution of
pollutant concentrations with the people estimated to reside near the source
to produce quantitative expressions of public exposure to the pollutant.  If
the pollutant of interest is one for which a cancer potency estimate has been
derived,  and this potency has been input to HEM, public cancer risk is
calculated.

    The  HEM also contains an area source model that is often used to estimate
exposure and risks from mobile sources or sources too numerous to model
individually.  The area source model can be used in limited geographical
                                     G-17

-------
 areas, e.g., parts of cities, entire counties, entire cities.  The HEM can be

 accessed on the National Computer Center Office of Research and Development

 and Development VAX computer.


    Input Data;  Inputs which are required for the model are the latitude and
    longitude of the source of the emissions (degrees, minutes, seconds);
    pollutant emission rate (kilograms per year); physical stack height
    (meters); internal stack diameter (meters); stack exit velocity (meters
    per second); and stack exit temperature (degrees Kelvin).  Optional data
    are cancer potency estimate (micrograms per cubic meter"1); indication
    whether source is subject to urban or rural meteorological conditions; and
    the five digit STAR (Stability Array) meteorological station identifier.

    Output:  This output of the model are the predicted maximum concentration;
    number of people estimated to be exposed to the maximum concentration;
    number of people residing within the area specified; public exposure
    (people X concentrations to which they are expected to be exposed to);
    table of predicted concentrations by wind direction and distance; maximum

will be completely menu driven and user friendly.  It will contain ISCLT, and
will be able to quantify uncertainties associated with dispersion modeling and

mobility;  indoor/outdoor relationships;  and population cohort analysis such

that risks to specified sensitive subpopulations can be estimated.   The model
may also contain a stable of dispersion models including a short-term model, a

Methodology for Reportable Quantities Adjustments

    Reportable quantities (RQs) are reporting triggers for episodic and
continuous releases of hazardous substances into the environment.  The
National Response Center (NRC) under CERCLA Section 103, and the State
Emergency Response Commission (SERC) and the Local Emergency Planning
Committee (LEPC) under SARA Section 304 must be notified if there is a spill
of release of any hazardous substance (as defined in CERCLA Section 101) equal
to or greater than its RQ.  There are five RQ levels:  1, 10, 100, 1,000, and
5,000 Ibs.  These levels provide an indication of relative hazard but not of
exposure or risk.

    EPA establishes RQs by separately evaluating six intrinsic physical,
chemical, and toxicological properties associated with the hazardous
substance:  aquatic toxicity (LC_n); acute mammalian toxicity (oral, dermal,
and inhalation LDg s); chronic toxicity (including a consideration of
minimum effective dose and the severity of the effect); potential
carcinogenicity; ignitability; and reactivity.  A separate RQ is assigned for
each criteria, and the lowest (most stringent) of these is used as the primary
RQ.  This primary RQ may then be adjusted based on the chemical's potential to
biodegrade,  hydrolyze, and photolyze (BHP), and the hazards associated with
its BHP products.

    Input Data;   Existing data on carcinogenicity; chronic toxicity (including
    a consideration of minimum effective dose and the severity of the effect);
    acute mammalian toxicity (oral, dermal and inhalation LD5QS); aquatic
    toxicity (LC50);  ignitibility;  and reactivity.
    Output;   A level (1, 10, 100, 1,000, and 5,000 Ibs.)  at which a release of
    the substance must be reported to the NRC, SERC, and LEPC.

    About two-thirds of the Section 313 chemicals have RQs.  EPA may develop
RQs for the  rest.

 Modified  Hazardous  Air  Pollutant  Prioritization System  (MHAPPS)

     MHAPPS  is a qualitative computerized system used by the EPA Office of Air
 Quality Planning and Standards to rank hazardous air pollutants for further
 assessment.  The system prioritizes substances by scoring them in eight
 factors that reflect the concerns of EPA air programs:  oncogenicity/
 mutagenicity, reproductive and developmental toxicity, effects other than
 acute lethality, acute  lethality, potential for airborne release,
 bioaccumulation, and existing standards.  Worksheets formatted on a PC are
 used to compile the relevant data from seven standard references, including
 the  Registry of Toxic Effects of Chemical Substances (RTECS) and the Merck
 Index.  Based on these  data, scores for each of the eight factors are
 calculated separately using specific criteria, and the scores of closely
 related factors are then normalized and combined to give five group scores.
 Finally,  the group scores are weighted (to account for their relative
 importance), normalized and combined to give an overall score that is used to
 rank the  substance.  The main obstacle to using MHAPPS for Section 313
 assessment is that the system can be used only to prioritize chemicals
 released  into the air.

     Input Data;  Data from readily available summary and reference documents
     and computerized data bases (particularly RTECS).  Data are needed on
     oncogenicity, mutagenicity,  reproductive and developmental toxicity,
     effects other than acute lethality, acute lethality, potential for
    airborne release,  bioaccumulation,  and existing standards.  The potential
    for airborne release is based on production volume and vapor pressure.
    Any fields with missing data are given no weight in the ranking.
    Output;  Relative ranking score.

 [NOTE:   The Office of Air Quality Planning and standards (OAQPS) is currently
developing a ranking system that will prioritize groups of emmissions sources
 (source categorizing)  rather than individual compounds.  This system will
employ the current MHAPPS health effects scoring system but will replace  the
potential for exposure factor with exposure data specific to airborne
releases. ]

Remedial Action Priority System

    The Remedial Action Priority System (RAPS) was developed by the U.S.
Department of Energy (DOE) to help DOE prioritize its hazardous waste sites
for further investigation and possible remedial action.  RAPS is a computer
model designed to estimate health risk from sites containing hazardous or
radioactive waste.  The health risks are estimated for the entired exposed
individual assuming long-term average conditions of exposure (70 years).
Currently, RAPS does not consider environmental risks; however, it could be
modified to include an exposure and effects submodel for environmental
receptors.

    RAPS estimates human health risks from a site in four steps:  source
definition, transport,  exposure, and health effects.  A separate preliminary
hazard index (PI)  is developed using these steps for each chemical of concern
at a site.  The highest PI is then used as the basis for developing a single
final site score.   The site scores range from 1 to 100, with higher scores
indicating greater risk.  RAPS uses contaminant transport and exposure models
to produce an estimate of the health effects associated with a site,  and
explicitly bases the overall score for each site on an index of health
effects.  Users can choose from among 22 transport-exposure models in RAPS.

    Input Data;  Several different data elements are required to run  RAPS.
    RAPS can calculate or supply default data for some of the elements if the
    variables are  not known.
    •  For the source definition submodel, over 20 different data inputs are
       required concerning site characteristics, contaminant characteristics,
       and climatological data.
    •  For the atmospheric transport submodel, RAPS incorporates over 30
       different data elements concerning climatological information,
       characteristics  of the point of release, physical characteristics of
       the contaminant, rates of emission, and location of human receptors.
    •  For the overland transport submodel, RAPS requires over 10 data
       elements relating to geology, precipitation, and topography.
    •  For the ground-water transport submodel, RAPS requires approximately 20
       elements of geological data.
                                     G-24

-------
    •  For the surface water transport submodel, RAPS requires approximately 5
       data elements related to discharge characteristics, flow parameters,
       and location of receptors.

    •  For the exposure assessment submodel, over 20 data elements are used,
       relating to irrigation, soil concentration, recreational water usage,
       aquatic food usage, and bioaccumulation and transfer potential.

    •  The health risk component of RAPS considers the type, time, and
       duration of exposure and the location and size of the exposed
       population.

    Output;   RAPS scores sites on a scale of 0 to 100, assigning higher scores
    to sites that pose greater potential risk.  The system provides a
    quantitative expression of risk and explicitly bases the overall score for
    each site on an index of health effects.

    An obstacle to using RAPS for Section 313 assessment is that the system
requires RfDs and cancer potency factors (q*s)  for the chemicals being
assessed.  A substantial number of 313 chemicals do not have these "toxicity
scores."  RAPS also requires a large amount of data that will be expensive and

time-consuming to collect.

 not  cause a health problem.

 Exposure to chemical  combinations that
 cause  toxic effects to  be added.   For
 instance,  if chemical A produces  1 unit
 of disease and  chemical B produces 2
 units  of disease,  then  chemicals  A and
 B produce  3 units  of  disease.

 A side effect which is  never  desirable
 and  is deleterious to the well-being of
 organisms,  such as allergic reactions.

 Surrounding.  Ambient temperatures are
 temperatures of the surrounding area
 (e.g., air  or water).

 When chemical combinations or mixtures
 produce  a  less  than additive  effect.
 For example,  if chemical  A produces  2
 unit of  disease and chemical  B produces
 4 units  of  disease, then  chemicals A
 and B  produce 3 units of  disease.

 An underground  geologic formation
 containing  water which  may be a source
 of public drinking  water.

 The accumulation and  concentration of a
 chemical in  an  organism.

 The degree  to which a substance becomes
 available to the target tissue after
 dministration or exposure.

A rapid  release of  short  duration.

Material, other than  the principal
product,  that is produced or generated
as a consequence of an  industrial
process.

major portion of a lifetime to an
environmental alteration that may or
may not cause a health problem.

of storing 550 million characters (as
compared  to a magnetic floppy disc,
which can store only 1.2 million
characters).  Information can be read
from the disc, but not added or deleted.

One of two general air pollutant types

Ground-Water Classification System
Guidelines
A  component of  risk assessment that
involves describing the nature and size
of the population exposed to a
substance and the magnitude and
duration of exposure.  The evaluation
could concern past exposures, current
exposures, or anticipated exposures.

The estimation  of a value beyond the
known range on  the basis of certain
variables within the known range, from
which the estimated value is assumed to
follow.

Chemicals with  acute lethality have the
potential for causing death in
unprotected populations after
relatively short exposure periods at
low doses.  On  the basis of toxicity
criteria, EPA identified a list of
chemicals (Section 302 of Title III of
SARA) with acute toxicity from the more
than 60,000 chemicals in commerce.

All buildings,  equipment,  structures,
and other stationary items which are
located on a single site or on adjacent
sites and which are owned or operated
by  the same person (or by any person
which controls, is controlled by, or
under common control with, such person).

EPA has established three classes of
ground waters to receive different
levels of protection under its Final
Ground-Water Classification Guidelines
and Ground-Water Protection Strategy
(EPA, 1988 and 1984).   Class I,  or
Special Ground Waters, are ground
waters highly vulnerable to
contamination and that are either
irreplaceable sources of drinking water
or ecologically vital ground waters
(i.e., ground waters supplying a unique
and easily disrupted ecosystem).  Class
II ground waters are all non-Class I
current and potential sources of
drinking water or water serving other
beneficial purposes (e.g., irrigation,
animal husbandry);  Class II has been
defined to include the majority of the
                                      H-6

 RfD  (Reference dose)
Risk
Risk analysis
Risk assessment
Risk management
An estimate  (with  uncertainty spanning
perhaps an order of magnitude or
greater) of  the daily exposure to the
human population (including sensitive
populations)  that  is likely to be
without appreciable risk of deleterious
effects during a lifetime.  The Rfd is
expressed in  units of mg/kg/day.

Probability of injury, disease, or
death under specific circumstances.

In the context of  Section 302 of SARA,
risk analysis is the third of a
three-step hazards analysis process for
emergency planning.  It requires an
estimation of both the occurrence of an
accidental chemical release (unique to
this process) as well as the subsequent
potential for exposure (with emphasis
on human exposure  to extremely
hazardous substances).  It is a
flexible, judgemental exercise that
results in qualitative risk
statements.

The process of estimating the
probability of occurrence of adverse
health or ecological effects.  A
chemical- or site-specific risk
assessment has two major components:*
(1) the estimation of the probability
of exposure(s) resulting from reported
releases, and (2)  the estimation of the
probability that adverse effects will
result from exposures.

Decisions about whether an assessed
risk is sufficiently high to present a
public health concern and about the
appropriate means  for control of a risk
judged to be significant.

Risk screening
Route of exposure
RQ (Reportable Quantity)
Safe
Sensitive Environment
 A  type  of  risk assessment  using  limited
 data.   The process  results in a
 qualitative expression of  risk (e.g.,
 high, medium, low).  Risk  screening is
 useful  for establishing risk-based
 priorities and information needs for
 follow-up  chemical- or site-specific
 risk assessment activities.  Although
 the risk screening process relies on
 general risk assessment principles, the
 data input requirements are less
 demanding  than those for risk
 assessment.

 Method by which the chemical is
 introduced into the biological organism.

 The quantity of a hazardous substance
 that triggers reporting under CERCLA.
 If a substance is released in a
 quantity that exceeds its  RQ, the
 release must be reported to the
 National Response Center (NRC), as well
 as to the State Emergency Response
 Commission (SERC) and the  Local
 Emergency Planning Committee (LEPC) for
 areas likely to be affected by the
 release.

 Condition of exposure under which there
 is a "practical certainty* that no harm
 will result in exposed individuals.

 Geographical areas bounded by legal,
 social, commercial, or biological
 constraints.  These include areas such
 as wetlands and national parks in need
 of protection by Federal,  State,  or
 even municipal statutes; areas deemed
 by society as desirable and therefore
 in need of protected from chemical
 contamination; areas where some human
 food source is grown (e.g., crops,
 catfish or rainbow trout)  or areas that
 are used commercially (e.g., lakes or
ponds where a fee is charged for
 boating or fishing); and areas vital
 for maintenance of a particular
population (be it terrestrial or
aquatic),  including shoreline/wetland

Pasquill stability classes (ranging
from "A" to "P") are meteorological
categories of atmospheric conditions.
Class A represents unstable conditions
under which there are strong sunlight,
clear skies, and high levels of
turbulence in the atmosphere—
conditions that promote rapid mixing
and dispersal of airborne
contaminants.  At the other extreme,
class F represents light, steady winds,
fairly clear nighttime skies, and low
levels of turbulence.  Under these
conditions,  airborne contaminants mix
and disperse far more slowly with air
and may travel at hazardous
concentrations further downwind than in
other cases.
