                      TRI EXPANSION PUBLIC MEETING
ISSUES FOR DISCUSSION

      EPA is developing proposed amendments to the Toxic Chemical Release Inventory
(TRI) program that would expand the scope of both facility and chemical coverage. This
issue outline is intended to give interested parties information the Agency has developed to
date.  It is also intended to stimulate discussion at the public meeting to be held at EPA on
May 29, 1992.
I.     Chemical Expansion

      EPA has developed draft numerical toxicity screening  criteria based  upon the
statutory provisions for listing and Agency experience with TRI petitions (see attachment 1).
These criteria allow the  Agency to put chemicals into 3 bins  of "Sufficient", "May Be
Sufficient", and "Insufficient" for listing. EPA has screened 600 chemicals  from a number
of different lists and found that a great majority of these are  "sufficient for listing". In
addition the Agency is also screening a list of approximately 600 active ingredient pesticides.
See attachment 2 for a compilation of chemicals reviewed and the screening results.

      Issue 1.      Are these numerical criteria adequate for making a basic sufficiency
                   determination?  How might they need to be modified?

      Issue 2.      Are  there chemicals, categories of chemicals, or additional lists of
                   chemicals that the Agency should screen?  Are there  errors in the
                   screening results provided to date?

      Issue 3.      What other weighing or ranking factors  should  be  employed to
                   prioritize chemicals for addition, especially if the Agency finds that a
                   large number of chemicals are "sufficient"? For example should there
                   be a relative ranking on toxicity on an individual chemical basis, on
                   chemicals in groups with similar effects, or by chemicals with impacts
                   on different environmental media?

      Issue 4.      Should production volume be used as a listing decision factor? What
                   alternatives should the Agency consider when a chemical clearly meets
                   the toxicity criteria but does not appear to be produced/imported
                   currently or historically in significant volumes?

-------
II.     Facility Expansion

       TRI currently covers the manufacturing sector of the economy; SIC Codes 20 - 39.
EPA has reviewed major Agency data sources to determine whether there is an indication
of significant use and/or release  of current and "new" chemicals.  Attachment 3 outlines
industries recommended for review with an estimate of the number of facilities involved.
Attachment 4 are brief descriptions of the three data bases selected for the preliminary
facility analysis.  (Additional information including data extraction and methodology will be
available  at  the public  meeting.)    Attachment 5 is a summary of  release  to  water
information at the 2-digit SIC code level followed by release data at the 4-digit level for SIC
code 49.   For  an example,  also  attached  is a  chemical  constituent breakout of the
wastestream reported for a particular 4-digit industry within SIC 49. Attachment 6 describes
the statutory authority for facilities and industrial group additions to section 313  reporting
which  is followed by selection factors being  considered by  the Agency workgroup in its
facility analysis.

       Issue 5.      Are there other sources of data that the Agency could use to help
                   develop a more comprehensive picture of TRI chemical use and
                   release outside of the  manufacturing sector?

       Issue 6.      Are there selection criteria or additional ranking factors beyond the
                   presence and  volume of  TRI  chemicals released that should be
                   considered by the Agency?   Such factors  could include toxicity of
                   chemicals used in an industry, proximity of facilities in an industry to
                   population centers or sensitive ecosystems.

       Issue 7.      What options should the Agency consider for  designating additional
                   facility coverage? For example should the Agency designate additional
                   whole divisions within the SIC system ( the statute designated Division
                   D - Manufacturing when it highlighted  SIC 20  - 39)? Or should the
                   Agency be more selective, even down to  the 4 digit level, depending on
                   the  evidence of  chemical use available?  Are  there  alternative
                   approaches based upon  categories of activities that could cut across
                   SIC codes but better target the reporting?

       Issue 8.      What other changes in the regulation are necessary in order to include
                   certain significant sources of release?  For example, changes in the de
                   minimis  requirements  might be  necessary in order  to obtain reports
                   from facilities in the utility industry.  A change in the definition of
                   process might be required in order to obtain reporting from treatment
                   and disposal facilities.

-------
III.    Overall Strategy for Expansion

       EPA has a finite capacity to handle additional TRI reports in a timely fashion.  The
current capacity  is  approximately 14 million data elements  per year.   The existing
requirements, when considering the impact of the Pollution Prevention Act data, may lead
to collection of as much  as 9 million data elements.  Therefore, decisions to expand TRI
must provide the  optimal mix of chemicals and sources that reach the most significant
environmental releases.

       Issue 9.             What should  take priority in terms  of using the existing  data
                          base capacity, data on releases of additional chemicals or data
                          from sources  that have  not previously reported?

       Issue 10.            What tradeoffs should the Agency consider in terms of optimal
                          use of the system capacity?
IV.    Threshold Considerations

       Current reporting thresholds are designed to capture listed chemicals that are being
manufactured or processed at facilities in quantities of 25,000 pounds or greater or that are
otherwise being used at levels equal to or greater than 10,000 pounds. Bills introduce in
Congress and a petition submitted by the Small Business Association (SBA) have proposed
"release based" thresholds to be included with or substituted for current operating thresholds.
A release based threshold criteria could be used to either include more facilities or exclude
current facilities.

       Issue 11.            Can  release-based  thresholds  be  adequately  enforced? Do
                          release-based thresholds demand a significant investment in up-
                          front estimation?

                                 EXHIBIT 2
                 HERITABLE MUTATIONS (CATEGORIES)

(1)    Positive data derived from human germ cell mutagenicity studies, when available,
       constitute the highest level of evidence for human mutagenicity.

(2)    Valid positive results from studies on heritable mutation events (of any kind) in
       mammalian germ cells.

(3)    Valid positive results from mammalian germ cell chromosome aberration studies  that
       do not include an intergeneration test

(4)    Sufficient evidence for a chemical's interaction with mammalian germ cells, together
       with valid positive mutagenicity test results from two assay systems, at least one  of
       which is mammalian (in vitro or in vivo).  The positive results may  both be for gene
       mutations or both for chromosome aberrations.  If one is for gene mutations and the
       other for chromosome aberrations, both must be from mammalian systems.

(5)    Suggestive evidence for a chemical's interaction with mammalian germ cells, together
       with valid positive mutagenicity evidence from two assay systems as described under
       #4. Alternatively, positive mutagenicity evidence of less strength than defined under
       #4, when combined with sufficient evidence for a chemical's interaction with
       mammalian germ cells.

(6)    Positive mutagenicity test results of less strength than defined under #4, combined with
       suggestive evidence for a chemical's interaction with mammalian germ cell.

(7)    Valid negative test results for all end points of concern.  (Although  definitive proof of
       non-mutagenicity is not possible, a chemical could be classified operationally as not a
       human germ cell mutagen.)

(8)    Inadequate evidence bearing on either mutagenicity or chemical interactions with
       mammalian germ cells.

 |L)  Subject facilities meet both the employee and chemical volume thresholds. Calculated based on information
    in "Analysis of Non-Responders to Section 313 of the Emergency Planning and Community Right-To-Know Act",
    Abt Associates, March 1990, prepared for Economics and Technology Division, Office of Toxic Substances, U.S. EPA.

 (2)  Calculated by ^mming that 3 to 66 percent of establishments with 10 or more employees will be subject
    to reporting requirements.  Estimated range based on information in the ratio of estimated subject
    for manufacturing facilities at the 2-digit SIC level.

 (3)  Data on the number of railroad establishments was not available, as the Bureau of Census does not collect
    collect this information.

 (4)  Data on state government facilities is incomplete.
 Notes

 Unless otherwise noted, all figures for establishments and establishments with 10 or more employees are from
 Table Ib, "County Business Patterns 1988", Bureau of the Census (CBP-88-01).

 a = Based on information from the Department of Agriculture's Farm Labor Survey.  According to the Survey, there
   were 2,143,000 farms in the U.S. in 1990, with 7,170 having 11 or more hired workers in the January survey, and
   15,420 having 11 or more workers in the July survey. Given the seasonal of agricultural work, the January figure
   used here represents a lower bound. (6/5/91 letter from the USDA National Agricultural Statistics Service.)

W= 1987 Census of Governments, Vol.3, No.2 (GC87(3)-2), Table 25.  This represents the number of governments
   providing a function, not the number of facilities.  The actual number of facilities may be more or less than this.

 c = Based on preliminary, unpublished data  from the Department of Labor .Bureau of Labor Statistics.Office of Employment
   and Unemployment Statitics, ES-202 Program.  The data represent reporting units, which may file a single report for
   multiple establishments. Thus, the number of establishments is a lower bound; due to the effects of aggregation,
   the estimate for establishments employing 10 or more workers may be an over- or under-estimate. Reporting units
   cover only federal civilian employment, and do not include Armed Forces personnel. (Letter from BLS Office of
   Federal/State Programs, 7/5/91.)

 d = Based on the 1990 State and Federal Correctional Facility Census, the 1988 Jail Census, and the 1989 Juvenile
   Facility Census (6/6/91 letter from Bureau of Census, Governments Division).

 Estimates based on data sources other than "County Business Patterns" (CBP) may not be comparable with CBP data.  Also,
 some of the CBP estimates (particularly those in transportation and utilities) have considerable uncertainties associated with
 them,  owing to the difficulty in assigning activity to a particular establishment.  In these cases, as well as in others,
 the definition of an establishment may differ from the definition of a facility under TRI.

ATTACHMENT 4                                     MAY 15, 1992

                DESCRIPTION OF THE DATA BASES SELECTED


Aerometric Information Retrieval System      (AIRS)
             *
      AIRS is the most current system that contains information on major sources under
the Clean Air Act. Major sources are defined as those facilities that emit over 100
tontyear of any criteria pollutant. There are about 20,000 major sources currently
reporting to AIRS.

      Data in AIRS is based on monitoring, materials balance calculations, or a
combination of the two. Reporting is on the seven criteria pollutants, of these VOCs and
PM10 are two which may contain many different chemical species. Estimates for some
section 313 and other chemicals can be estimated by using SPECIATE. SPECIATE
contains chemical specific emission factors (based on engineering and sampling
information) estimated for Source Category Codes (SCC). These estimated emission
factors can be applied to facility emission volumes to estimate the composition and
volume  of stack emissions at a particular facility.  Stack emissions can then  be aggregated
to the facility level to present cumulative data by SIC code.

      Facilities may also report on a range of other chemicals directly. Among these,
AIRS lists such chemicals as arsenic, beryllium, benzene, cadmium, etc. that are of
interest  to the expansion activity. In a case where a facility reports directly on a chemical
of interest, that information will be used in stead of the estimated SPECIATE value.

Biennial Report System (BRS)

      RCRA requires extensive reporting by facilities considered to be Large Quantity
Generators (LQGs) (facilities that produce RCRA hazardous wastes equal to or greater
than 1,000 kg/mo). Data reported by facilities that produce less than 1,000 kg/mo (Small
Quantity Generators) of a RCRA hazardous waste are less complete. THE TRI
expansion analysis will use data reported by all  facilities for 1989 (both LQGs and
SQGs).

      The Biennial Report  System is the reporting system for RCRA waste either
generated or received.  This reporting system is updated every other year with national
data made available approximately three years from the time of waste generation.

      Waste streams captured by this system are reported in RCRA waste codes.
Many of these are constituent-specific which have been matched to Chemical Abstract
Service (CAS) numbers of section 313 and other chemicals under review by the
expansion workgroup.

-------
      The RCRA reporting form contains space for entry of four (4) waste codes per
waste stream.  Generally, reports include four waste codes per waste stream and may
exceed that number. Volume of waste is reported at the waste stream level. Entry of
waste codes for a waste stream into BRS for 1989 data does not reflect the order of
waste codes originally reported by the facility.  Therefore, a decision was made to
apportion the volume equally among the waste codes listed for a particular waste stream
in order to estimate chemical specific volumes.

Permit Compliance System (PCS)

      Data on releases to water are being derived from the Permit Compliance System
(PCS) database. It contains data on sources that are permitted through the National
Pollutant Discharge Elimination System (NPDES).  All point sources discharging directly
to navigable waters must have an NPDES permit.

      Only major sources must submit data to PCS. Regions have discretion over
whether to submit data for minors.  (There are about 7,000 major sources and 63,000
minor sources with NPDES permits.) Municipal facilities  (Publicly Owned Treatment
Works, or POTWs) are classified as major if they have a flow rate over 1 million gallons
a day, or discharge to a water-quality limited stream segment.  Non-municipal facilities
are classified as major based on a scoring system that takes into account a number of
factors including SIC Code; type, volume, toxicity and temperature of the waste; and flow
and water quality factors of the receiving waters. The  database includes any federal
facilities that meet the definition of a major facility.

      Reporting is required monthly, although monitoring may be  at a different
frequency, depending on the pollutant and the permit conditions.

      Parameters covered by NPDES permits are very site-specific.  NPDES permits
cover over 1,000 physical and chemical parameters. Several parameters may exist  for the
same chemical (total lead, total dry lead, total dissolved lead, etc.).  Reporting is on the
basis of PCS parameters.  These in part are taken from STORET numbers, which can be
matched to CAS numbers.  PCS data is generally given as an effluent concentration. It
must be multiplied by a flow rate, given in the permit,  to estimate the total quantity
released by a facility.

ATTACHMENT 6                                              MAY 15, 1992

             STATUTORY CRITERIA FOR FACILITY ADDITIONS TO
                       THE TOXIC RELEASE INVENTORY

Statutory Criteria.
  Section 313-(b)(l)(B) provides EPA with the authority to add additional industries to §
313 reporting requirements.

SIC or Industry Group Additions
       Section 313 (b)(l)(B) authorizes EPA to add SIC codes to the extent necessary to
provide that each SIC code that is subject to section 313 is "relevant to the purposes of ^
[section 313]."

       Language from H.R. 2005 Conference Report p.292 states that "This authority is
limited, however, to adding SIC codes for facilities which, like facilities within the
manufacturing sector SIC codes 20 - 39, manufacture, process or use toxic chemicals in a
manner such that reporting by these facilities is relevant to the purposes of this section".
Section 313 now includes only facilities in the Manufacturing Sector (SIC codes 20-39).
However, "manufacturing-like" is not explicitly defined, which would allow for a review on
a case-by-case basis for any industry whose addition would be in accord with  the
purposes of the act.

Facility Specific Additions
       Section 313 also provides EPA with the authority to add specific facilities.
Discretionary Application to Additional Facilities section states that, "the Administrator,
on his own motion or at the request of a Governor...may apply the (reporting)
requirements to the owners and operators or any particular facility that manufactures,
processes, or otherwise uses a toxic chemical listed under subsection (c) if the
Administrator determines that such action is warranted on the basis of toxicity of the
toxic chemical, proximity to other facilities that release the toxic chemical or to
population centers, the history of releases of such substances at such facility,  or (such
other factors) as the Administrator deems appropriate".

-------
 EVALUATION ELEMENTS FOR FACILITY ADDITIONS UNDER CONSIDERATION
                             BY THE WORKGROUP

      The following is a list of elements defined by the workgroup as possible factors to
consider in the selection and ranking of additional facilities or industry categories.

1.    Volume of releases and transfers:
      Volume will be defined in terms of pounds per year of releases and transfers
      (although it may be necessary to use a surrogate for this in some instances).
      Data on the volume of releases and transfers provides a specific link between the
      facility or industry and the presence of a TRI chemical in significant amounts.

2.    Number of facilities within SIC code:
      Indicates how many unique facilities operate under the SIC code.
      One aspect of this criterion is that number of facilities may be directly related to
      volumes of use and release of toxic chemicals.  The number of facilities is also
      used to estimate respondent burden (cost to industry of the regulation).

3.    Number of facilities in SIC code with > 10 employees:
      TRI reporting is required only for facilities with 10 or more full-time employees.
      If a large  share  of the facilities in an industry have fewer than 10 employees,
      adding that industry may not  capture much of the releases associated with it and,
      therefore, might rank lower than another industry.

4.    Relative toxicity of chemicals used:
      It may be possible to  classify  the toxicity of chemicals into some relative
      categories, signifying different levels of toxicity and concern. A "score" for an
      industry could be developed based upon the chemicals known to be used or
      released by that industry.

5.    Geographic location of release and size of surrounding population:
      Geographic location could be measured in units such as zip code,  Standard
      Metropolitan Statistical Area, or latitude and longitude. The size  of the
      surrounding population could be presented in numerical estimates, or in
      categorical descriptions  (urban, suburban, rural).  The workgroup  may elect to
      incorporate known sensitive areas such  as primary aquifers into the analysis.

6.    Media considerations:
      Indicates whether releases are to air, water, or land.  One use of this criterion
      might be to count the number of media that a chemical is released to, and place a
      larger weight on chemicals released to multiple media.  Alternatively, there may
      be some overriding concerns about releases to a particular media  by a particular
      industry that would cause that industry to be ranked higher than another.

-------
7.    Utility for other regulatory initiatives:
      Would indicate whether the TRI data collected by adding the industry would be
      especially useful for actions under the Clean Air Act, Clean Water Act, TSCA,
      etc. TRI assists many program offices in identifying wastes that they presently do
      not regulate or for which additional information is relevant. If a program office
      considering regulating (or further regulating) a particular industry, then  TRI data
      from the industry could prove especially useful in developing the regulations.

8.    Maximization of reporting for specific chemicals:
      TRI reporting currently covers only a part of the uses of the TRI chemicals.
      Additional industries could be selected with the goal of creating a comprehensive
      picture of uses and releases of one or more chemicals (i.e., aim for reporting on
      100% of the uses of some subset of TRI or other chemicals). This is related to
      utility for other regulatory initiatives.  For example, the 33/50 program has
      targeted 17 chemicals based on their toxicity and use in commerce.  It is the
      Agency's intention to focus attention on these chemicals, and gain commitments to
      reduce releases voluntarily.  Maximizing reporting on these 17 chemicals might
      widen the base of participation in the 33/50 program.

9.    Degree of pollution prevention/waste reduction potential:
      TRI has been used to identify chemical use patterns by various industries in order
      to construct waste reduction strategies.  Reporting to TRI could make these
      facilities aware of the amounts of wastes that they generate. Actual waste
      reduction could then be industry or community driven.

10.   Technical expertise within industry to complete Form R:
      Would indicate whether facility operators are likely to be able to fill  out the Form
      R (which is used for TRI reporting) correctly. The reporting Form R requires
      process or other technical knowledge that most operators of some facility types
      would not have. Therefore, inclusions of such industries  may yield reports of
      questionable value  and would likely set up a high non-compliance situation.

11.   History of improper releases within industry:
      Would indicate whether facilities in the industry have had a history of violating
      permit limitations, or releases in excess of reportable quantities, etc.   If this type
      of facility specific information can be aggregated to the industry level, then a
      compliance "profile" for that industry could add to a weighing scheme when
      considering a  particular industry.

12.   Uniformity/homogeneity of facilities or processes within an industry:
      Some industries such as dry cleaning operations  and gasoline stations generally
      operate in a fairly standard  manner,  and typical  chemical uses and releases could
      be  calculated  based on emission factors and the  volume of business or population
      density where operations normally occur.  Instead of requiring such operations to
      fill  out a Form R, EPA could develop estimates of total industry contributions as
      well as provide model calculation methods for the database user who wishes to
      add such potential release figures for such facilities to localized analyses.
