                             PREFACE
     Executive Order 12044,  "Improving Government Regulations,"
directs each executive agency to adopt procedures to improve
existing and future regulations.  An important provision of this
order is that agencies consider and analyze meaningful
alternatives before regulations are issued.  For all significant
regulations with major economic consequences, agencies must
conduct a regulatory analysis, in which they carefully examine
alternative approaches.  The U.S. Environmental Protection Agency
(EPA) described its plan for implementing the Executive Order,
and listed criteria for conducting regulatory analyses, in the
FEDERAL REGISTER of May 29,  1979 (44 FR 30988).

     In this document, EPA presents a draft Regulatory Analysis
of proposed rules implementing section 5 of the Toxic Substances
Control Act (TSCA).  Section 5 of TSCA requires manufacturers and
importers to notify EPA 90 days before they manufacture or import
a new chemical substance for commercial purposes.  Section 5 also
requires persons to notify EPA 90 days before they manufacture,
import, or process a chemical substance .for a significant new
use, as determined by rule.  EPA proposed regulations to
implement section 5 requirements, and to establish premanufacture
notice and review procedures, in the FEDERAL REGISTER of January
10, 1979 (44 FR 2242), October 16, 1979 (44 FR 59764), and August
15, 1980 (45 FR 54642).  These rules will have an impact on major
segments of the chemical industry, and they will affect the
introduction of new chemical substances into commerce.
Therefore, EPA has determined that the rules meet the criteria of
its own guidelines and of Executive Order 12044 for a regulatory
analysis.

     The draft Regulatory Analysis examines the major
alternatives that EPA considered in developing section 5 rules
and explains the rationale for EPA's choice among the
alternatives.  EPA has based the analysis in part on the work of
two contractors, Arthur D. Little, Inc. (ADL) and ICF
Incorporated (ICF), which prepared economic impact analyses of
major parts of the proposed  rules.  The studies by Arthur D.
Little, "Impact of TSCA Proposed Premanufacturing Notification
Requirements" (December 1978) and "Estimated Costs for
Preparation and Submission of Reproposed Premanufacture Notice
Form" (September 1979) have  already been published and are
available from the Industry Assistance Office of the EPA Office
of Toxic Substances.  EPA published a summary of ICF's proposed
methodology in the FEDERAL REGISTER of June 10, 1980  (45 FR

-------
                              -IV-
39450), and it is now publishing the IGF report, "Economic Impact
Analysis of Proposed Section 5 Notice Requirements," together
with the draft Regulatory Analysis.  The proposed Economic Impact
Analysis and additional copies of this draft Regulatory Analysis
are available from the Industry Assistance Office.

     EPA encourages interested members of the public to submit
written comments on the draft Regulatory Analysis and the
proposed Economic Impact Analysis.  EPA will consider these
comments when preparing the final versions of these documents and
the final section 5 rules.  The final analyses will be published
when the section 5 rules are promulgated early in 1981.  Comments

                         I.   INTRODUCTION
A.   Purpose of TSCA

     The Toxic Substances Control Act of  1976 gives  the
Environmental Protection Agency broad authority  to regulate  the
manufacture, processing, distribution in  commerce, use,  and
disposal of chemical substances.  In doing  so, it fills  a major
gap  in U.S. environmental and  toxic-chemical regulation.
Previous laws limited Federal  regulation  of hazardous  substances
to particular uses  (for example, as drugs,  pesticides, or
consumer products)  or to particular conditions of exposure  (for
example, exposure to hazardous substances in the workplace or  to
air  and water pollutants).  TSCA, however.-  makes possible the
regulation of toxic substances in all phases of  their  commercial
life cycle.  It gives EPA the  authority to  regulate  certain
hazards not readily controlled by other laws, and it enables EPA
to control hazardous substances early in  their life  cycle.

     In TSCA, Congress took a  preventive  approach to the
regulation of chemical substances. v. A major focus of the Act is
to prevent harm to  health and  the environment, rather  than to
address hazardous situations only after the damage has been
done.  This approach not only  protects humans and the  environment
more effectively than an approach directed  only  at existing
hazards, but it allows for more efficient and economical
regulation.  If hazardous substances are  controlled  early in
commercial development, or before they enter commerce, the direct
cost to the regulated industry, to labor.- and to the economy in
general will be low.  This preventive approach is embodied in
particular in section 5 of the Act, which gives  EPA  the  authority
to review risks associated with new chemical substances before
they enter commerce and risks  associated  with new uses of
existing chemical substances that the Agency has determined  to be
"significant new uses."

     B.  Scope of Section 5

     Section 5 of TSCA requires chemical  manufacturers and
importers to notify EPA at least 90 days  before  manufacturing  or
importing a new chemical substance for a  commercial  purpose.   New
chemical substances are those  that are not  on the TSCA Chemical
Substance Inventory, first published on June 1,  1979,  as the
Initial Inventory,  and supplemented on July 30,  1980, by a
Revised Inventory.  In addition, under regulations proposed  on
August 15,  1980 (45 FR 54642), persons would be  required under
section 5 to notify EPA if they intended  for the first time  to
process substances  for TSCA commercial purposes  that were
manufactured or imported for purposes exempt from TSCA reporting.

-------
                                -2-
      Once EPA receives a section 5 notice,  the Agency has 90 days
 to review it, unless for good cause it extends the review period
 under section 5(c) for up to an additional 90 days.  During the
 review period, EPA may act under section 5(e) or 5(f) to regulate
 the production or use of the new chemical substance.  Section
 5(e) authorizes EPA to prohibit or limit the manufacture,
 processing,  distribution in commerce,  use,  or disposal of a new
 chemical substance until the submitter provides sufficient
 information for an evaluation of its health and environmental
 effects.  The Agency can take this action if it determines that
 the available information is insufficient fox a reasoned
 evaluation and either (1) the substance may present an
 unreasonable risk of injury to health or the environment, or (2)
 the substance will be produced in substantial quantities and
 there may be significant or substantial exposure to the
 substance.   Under section 5(f),  EPA may regulate a new chemical
 substance if it finds that there is a reasonable basis to
 conclude that the manufacture, processing,  distribution in
 commerce,  use,  or disposal of the substance will present an
 unreasonable risk of injury to health or the environment.

      If EPA  or a Federal court has not banned manufacture,
 processing,  or import of the chemical substance during the review
 period,  these activites may begin, subject to limits or testing
 requirements imposed during the review period.  At that time,  the
 substance is added to the Inventory.  Thereafter.-  any person may
 manufacture  or import the substance without giving notice to the
 Agency.

      Premanufacture notification requirements went into effect on
 July 1,  1979,  30 days after the publication of the Initial
 Inventory.   An Interim Policy, published by EPA in the FEDERAL
 REGISTER of  May 15,  1979 (44 FR 28558) governs the submission  and
 review of notices until final rules are issued.  EPA proposed
 rules  and  notice forms to implement a premanufacture notification
 and  review program in the FEDERAL REGISTER of January 10,  1979
 (44  FR 2242),  and reproposed the rules and forms in part in the
 FEDERAL  REGISTER of October 16,  1979 (44 FR 59764).  EPA has also
 proposed processor notification rules  in the FEDERAL REGISTER  of
 August 15, 1980 (45 FR 54642).  These  rules would require that
 persons  notify  EPA 90 days before they process substances which
 were previously exempt from TSCA reporting.

     The draft  Regulatory Analysis discusses the major issues
 that arose in  developing these proposals,  the alternative
 approaches to  their resolution that EPA considered,  and  the
 rationale  for EPA's choice among the alternatives.   The  proposed
 rules  will be promulgated early  in 1981.  The final Regulatory
Analysis will be published at the same time.

     C.  Section 5 Rulemaking

     1.  Possible Components of a Section 5 Rulemaking

     In proposing these rules, EPA considered the possibility of
a broad rulemaking fully implementing section 5.  Such a
rulemaking could include:   (1) Clarification of the nature and
scope of reporting obligations, (2) Instructions on what
information must be submitted in section 5 notices, (3) An
explanation of Agency procedures for reviewing and acting on
notices, (4) Procedures for exempting certain chemical substances
from all or part of section 5 requirements, and (5) Procedures
for following up new chemical substances after they have entered
commercial production.  The rules proposed on January 10, 1979,
October 16, 1979, and August 15, 1980, address the first three
elements; the other two elements will be the subject of later
rulemakings.

     In addition, the premanufacture notification program could
include guidance for premanufacture testing, discussed in the
FEDERAL REGISTER notice "Discussion of Premanufacture Testing
Policy and Technical Issues:  Request for Comment," published on
March 16, 1979  (44 FR 16239).  This guidance would not provide
mandatory requirements for premanufacture testing.

         a.  Clarification of reporting obligations.  A section 5
rulemaking might clarify the nature and scope of the notice
obligation, giving submitters a clear understanding of the extent
of their responsibilities under section 5.  Simply citing the
language of the statue in many cases would not provide clear
guidance.  Under the Interim Policy of May 15, 1979, which
generally uses this approach, EPA has often been required to
answer industry questions on notice requirements and to clarify
its interpretation of the Act.  In a more extensive rulemaking,
EPA could explain in detail its interpretation of the Act instead
of responding to individual inquiries.  In addition, the rules
could explain the scope of reporting obligations.  For example,
they could specify who should submit a notice as an "importer,"
and they could define the extent to which submitters would be
obligated to ask customers  for information on processing, distri-
bution in commerce, use, or disposal of new chemical substances.
In this way, the rules would promote a consistent EPA approach
and reduce uncertainty.  This was the approach that EPA took in
the January, October, and August proposals.

         b.  Information requirements.  Section 5(d) of TSCA
requires that notices include test data in the possession or
control ot the submitter, and, insotar as it is known to or
reasonably ascertainable by the submitter, information on

-------
                                -4-
 chemicaSL  identity;  proposed  categories  of use;  proposed volume of
 production;  byproducts  resulting from manufacture,  processing,
 use,  or disposal; workplace  exposures;  and manner or method of
 disposal.   In  a  section 5  rulemaking, EPA could define
 information  requirements by  citing the  relevant sections of the
 Act;  it could  provide a narrative explanation of these
 requirements and possibly  require other information related to
 exposure  throughout the life cycle of the substance; or it could
 provide a  notice form to clarify and provide a  standard format
 for  the information described in the narrative  explanation.

      Under the Interim  Policy,  EPA has  found that the first
 alternative  does not provide adequate guidance  to submitters,  and
 in many cases  this  approach  does not give the Agency enough
 information  to evaluate possible risks  associated with new
 chemical  substances.  In the second alternative,  the Agency could
 clarify such terms  as "test  data" and "disposal," and it could
 specify the  submission  of  other information necessary for an
 evaluation —  for example, information  on exposure associated
 with  consumer  uses.  The Agency could also develop notice forms
 to accompany the rule.  These forms would allow clearer
 instructions on  what information the submitter  would have to
 include in the notice,  and they would greatly facilitate EPA's
 review of  notices within the short time allowed by the Act. EPA
 proposed  such  forms in  the January and  October  rules.

          c.  Explanation of  Agency procedures.   The rules could
 describe  the procedures by which the Agency would review,  and
 possibly  act on, notices.  in this way,  the rules would provide
 submitters with  a clear idea of what they could expect,  and they
 would eliminate  some of the  uncertainty surrounding the
 submission of  a  notice.  The rules could establish policy and
 procedures  for handling confidential information; for processing
 and reviewing  notices,  including a policy on incomplete
 submissions; tor securing  additional data from  the submitter or
 other persons  during the notice period;  and ror using the
 regulatory authorities  ot  sections Me;  and 5(±).  Again,  this is
 the approach that EPA has  adopted in its proposed rules.

         d.  exemption  policy.   The rule could  establish a
 comprehensive  exemption policy under section 5(h),  including
 exemptions for test  marketing,  for research and development, and
 for substances determined  not to present an unreasonable  risK  ot
 injury to health or  the environment.  The January proposal
 discusses the  research  and development  exemption  under section
 5(h)(3),  which exempts  persons  who manufacture  or process  a new
 chemical substance  solely  tor research  and development "in small
quantities."   But it does  not specifically define the  terms  ot
the exemption, including the meaning of  "small  quantities."  The

-------
                               -5-
Agency may in future rulemakings establish numerical or other
more precise definitions of small quantities for specific
substances or groups of substances.

     The proposed rule also discusses test marketing exemptions,
which are granted upon a showing that the test marketing of the
substance will not present an unreasonable risk of injury to
health or the environment.  The proposed rule, however, does not
fully define the requirements for a test marketing exemption, nor
does it specify the procedures by which EPA will review test
marketing exemption applications.  Under the Interim Policy, EPA
has found that the absence of a framework for test marketing
exemptions can impose a burden on the submitter.  In a future
rulemaking, EPA may clarify the test marketing exemption and
possibly develop a test marketing application form.

     EPA also has the authority to develop an exemption policy
under section 5(h)(4).  This section allows the Agency, upon
application and by rule, to exempt manufacturers or importers
from all or part of the section 5 requirements if it determines
that the manufacture, processing, distribution in commerce, use,
and disposal of a new chemical substance will not present an
unreasonable risk to health or the environment.  In the future,
EPA may propose procedures for exempting substances under this
section.

         e.  New-chemical followup program.  A section 5
rulemaking could establish a new-chemical followup program.  Such
a program would allow EPA to obtain information on selected new
chemical substances after they have entered commercial
production, and to reassess certain new chemical substances
before they are produced for new uses that may significantly
increase their risk to human health or the environment.  EPA
could establish the program under two TSCA authorities:  the
section 8(a) reporting authority and the section 5(a)(2)
significant new use authority.

     Although the proposed rules do not implement  followup
procedures, EPA will soon propose significant new use rules for
specific new chemical substances.  These proposed rules will
require persons to notify EPA 90 days before they manufacture or
process the substances subject to the rules for a  significant new
use, as defined by the rules.  EPA is also developing a model
significant new use rule and a model section 8(a) reporting rule
that can be applied to specific new substances of concern.  The
Agency will publish an Advance Notice of Proposed Rulemaking for
these model rules in the near future.  The model rules will
include notification and review procedures, information
requirements, and definitions of possible significant new uses.

-------
                                -6-
 EPA will  apply  these  model  rules  to  specific  new chemical
 substances  in abbreviated  rulemakings.   The Agency may also apply
 the model significant new  use  rule to existing chemicals as an
 interim measure before it  develops a general  framework for using
 the significant new use authority for existing chemicals.

          f.   Testing  guidelines.   As discussed in the January
 proposal  and  the Discussion of Premanufacture Testing and Policy
 Issues  of March 16, 1979,  EPA  could  publish premanufacture
 testing guidance.  Such guidance  would  recommend the types of
 data generally  needed for  premanufacture risk assessment and
 appropriate test methods for developing these data.   EPA has
 decided to publish premanufacture testing guidance consistent
 with the  premarket "base set"  of  data developed by the
 Organization  for Economic  Cooperation and Development (OECD).
 This testing  guidance will  be  published in the FEDERAL REGISTER
 in  the  near future.

      2.   Components of Proposed Rulemaking

      The  section 5 rules proposed on January  10,  1979,  October
 16,  1979, and August  15, 1980,  are limited in scope;  they specify
 information requirements,  provide notice forms,  clarify the
 nature  of the reporting obligation,  and explain Agency procedures
 for reviewing and acting on notices.  EPA has not proposed a
 comprehensive exemption policy, or a new-chemical followup
 program.  These will  be the subject  of  later  rulemakings.  This
 limited approach to section 5  rulemaking will ensure an effective
 premanufacture  review program,  without  delaying the promulgation
 of  rules  until  all issues  surrounding possible section 5
 rulemakings have been resolved.

      The  major  provisions  of the  proposed approach are summarized
 below.  EPA is  considering  alternatives to each of these
 provisions; the alternatives,  and EPA's rationale for its
 preferred approach, are discussed in this draft Regulatory
 Analysis.

          a.   Reporting requirements.  EPA prefers the approach of
 the  October 16  reproposal.   In this  approach,  submitters would be
 required  to complete  a limited form,  asking for information on
 chemical  identity, manufacturing  process,  occupational  exposure,
 environmental release and  disposal,  and commercial user and
 consumer  exposure.  They would also  submit all test  data in their
possession or control and a description of any other  data known
 to or reasonably ascertainable by them.   EPA  would select
 substances of concern for detailed review on  the  basis  of
 information in  the notices.  For  the  few substances  subject to
such  a review,  EPA could require  additional data  from  the
submitter or  certain  other  persons under the  supplemental
reporting authority described  below.

-------
                               -7-
         b.  Confidentiality.  There are  four  issues  involving
confidentiality:   (1) How the  submitter claims information
confidential;  (2) When he must substantiate his claims;  (3) How
EPA will handle confidential information  in public  notices; and
(4) When EPA will disclose  confidential chemical  identity as  data
underlying a health  and  safety study.

     In the preferred approach,  submitters would  assert  claims of
confidentiality by linking  the information claimed  confidential
to certain categories of information established  by EPA.  The
submitter would be required to substantiate all confidentiality
claims at the  time the notice was submitted.   Confidential
information would be masked by generic names or descriptions  in
section 5(d)(2) and  other public notices.  Confidential  chemical
identity that  is underlying data to a health and  safety  study
would not be disclosed until commencement of manufacture.  The
Agency, however, is  also considering the possibility  of
protecting chemical  identity for a set period  after manufacturing
begins.

         c.  Incomplete  submissions.  On January  10,  EPA proposed
an approach to incomplete submissions that divided  deficiencies
into major and minor categories.  If the deficiency was  major
(for example,  failure to supply known or reasonably ascertainable
information required by  the form), EPA would not  review  the
submission, and the  notice  period would not start.  If the
deficiency was minor (for example, typographical  errors  that  make
answers to any questions unclear or ambiguous), the notice period
would be suspended until the deficiency was corrected.   If the
submitter corrected  the deficiency within 30 days,  EPA would
start the review clock at the point where it stopped.  If the
deficiency was not corrected, EPA could return the  notice as
incomplete and stop  the  review.  EPA is also considering a
narrower set of criteria for determining that  a notice does not
meet the requirements of the Act.  Under this  alternative, EPA
would not stop the review period if it found minor  deficiencies
in a notice.  The January 10 proposal did not  include appeal
procedures for submitters;  the Agency, however, is  considering
such procedures for  the  final rule.

         d.,  Customer contact.  Frequently, customers will have
information on the processing, uses, and disposal of  new chemical
substances that is not known to the notice submitter.  This
information might be necessary for EPA's evaluation.  To secure
the information, EPA prefers an alternative approach  discussed in
the Preamble to the  October 16, 1979, reproposal.   As described
in the Preamble, this approach would require the  submitter to
indicate in the notice the  number of customers who  had made a
firm commitment to purchase the substance for  a use unknown to
him.  The submitter  would also be required to  estimate the
percentage of production volume that these customers  would
purchase in the first three years of manufacture.

-------
                                -8-
          e.   Definition  of  importer.   Importers  as  well as
manufacturers are  subject to the notice requirements of section
5.   EPA  prefers  a  broad  definition  of  importer,  proposed on
January  10,  1979,  which  includes all possible parties in an
import transaction.   On  September 23,  1980,  EPA  published a
clarification of this definition, which would require that the
"principal  importer"  submit the  notice (45  FR 63806).

          f.   Importer contact of foreign manufacturers/suppliers
EPA proposes that  importers be required to  contact  foreign
manufacturers and  suppliers,  who would be asked  to  submit a
Foreign  Manufacturers/Suppliers  Form.   This approach was
originally  proposed on January 10.  EPA is  now considering an
abbreviated form,  which  might be modeled on the  October 16 form,
or  which might be  still  further  reduced so  that  it  asks only for
health and  safety  data and  risk  assessments.

          g.   Exporters.  On January 10 and  October  16,  EPA
proposed that manufacturers of chemicals solely  for export be
required to submit a  section 5 notice.   The notices would not
include  information on uses and  exposure occurring  outside of the
United States.

          h.   Supplemental reporting.   In certain cases, EPA may
require  additional information from the submitter,  from potential
processors,  or from other persons during the review period in
order to complete  its evaluation.   EPA prefers the  approach to
supplemental reporting of the October  16 reproposal.  In this
approach, the Agency  could  require, under a section 8(a)  or 8(d)
letter-writing authority, that certain persons during the review
period provide specified types of information necessary for
assessing the potential  risk of  a new  chemical substance.  The
submitter of the notice, processors, manufacturers  or importers
of  reactants of  unknown  composition, and persons who have
relevant health  and safety  studies  could be subject to
supplemental reporting under this authority.   Persons could
appeal the  reporting  requirement to EPA,  and the Agency could
only exercise the  supplemental reporting authority  durihg the
review period.

          i.   Processor reporting.   In  EPA's preferred approach,
proposed  on  August 15, 1980,  persons would  be required to notify
the Agency  90 days before they processed substances which were
previously  exempt  from TSCA reporting.   Specifically,  this
requirement  would  apply  to  processors  of chemical substances
manufactured without  a commercial purpose (byproducts);
substances manufactured  or  imported for research and development
or test  marketing; substances manufactured  or imported  as
pesticides,  tobacco or tobacco products,  nuclear materials,
firearms  or  ammunition,  foods, food additives, drugs,  or
cosmetics; and substances manufactured before January  1,  1975,
and not processed  after  that  date or reported for the TSCA
Inventory.

-------
                               -9-
         j.  Possession or control.  Section  5  requires that
notice submitters include in their notices test data  that was  in
their "possession or control."  In the January  10 proposal, EPA.
defined "possession or control" to mean in the  possession or
control of (1) the submitter, or  (2) any subsidiary,  parent
company, or subsidiary of the parent company, if the  subsidiary,
parent company, or subsidiary of  the parent company was involved
in commercializing the new chemical substance.  Information is in
the possession or control of a company if it  is in company files,
commercially available data bases to which the  company has
purchased access, or files maintained by employees associated
with the commercial development of the new chemical substance.

     3.  Economic Impact of Proposed Rules

     To evaluate the potential economic impact  of proposed
section 5 notice requirements, EPA requested  that ICF
Incorporated analyze the various  provisions of  the proposed rules
and estimate their potential effects on the chemical  industry.
The ICF report, "Economic Impact  Analysis of  Proposed Section  5
Notice Requirements," served in part as a basis for this draft
Regulatory Analysis.  The Economic Impact Analysis is being
published along with the Regulatory Analysis.

     The ICF analysis incorporates the estimated costs for
preparation of the October 16 proposed form originally developed
by Arthur D. Little ("Estimated Costs for Preparation and
Submission of Reproposed Prernanufacture Notice  Form, " September
1979).  The cost of completing the mandatory  sections of the
forms would range from $1,000 to  $8,900 and costs for asserting
and substantiating confidentiality from $900  to $6,400 (pp. 30,
33).  However, ICF concluded that these costs are not the major
source of the economic impact; rather, the indirect costs
associated with uncertainty would generally outweigh  the direct
costs of complying with notice requirements.  These indirect
costs would reflect uncertainty about direct  costs, possible
trade secret disclosure, and possible restrictions on the use  of
new chemical substances.

     According to the ICF analysis, section 5 requirements are
likely to cause a short-run decrease in the number of new
chemicals introduced as chemical  companies shift their activities
into "safe" chemicals.  There may be a disproportionate burden
for smaller companies, both because the volume  of their new-
chemical sales is lower and therefore produces  fewer  profits over
which to absorb notice filing costs and because they  may lack  the
legal and technical expertise to  comply efficiently with section
5 requirements (pp. x, 98-100).   The study concludes  that the
notice requirements will have the greatest effect on  innovative
segments of the chemical industry; products most likely to be
affected are catalysts,  surfactants, cyclic intermediates,
rubber-processing chemicals, plasticizers, miscellaneous
synthetic organic chemicals, adhesives and sealants,

-------
                               -10-
miscellaneous industrial inorganic chemicals,  and plastics  and
resins (p. ix).  Current data, however, do not allow quantitative
estimates to be made of the effects of section 5 requirements  on
businesses of different sizes, different  segments of the  chemical
industry, or the general rate of chemical innovation.  According
to the IGF analysis, it is doubtful that, even if the  data  were
available, accurate quantitative predictions could be  made.

     4.  Benefits of Proposed Approach

     The proposed section 5 rules will establish clear, effective
notification requirements and review procedures that will promote
an efficient EPA. review of new chemical substances.  3y
presenting information in a standard format, the forms will  allow
EPA to determine rapidly whether a notice meets the statutory
standard, to decide whether a substance requires detailed review
or whether more information is needed for an adequate  review,
and, if necessary, to support regulatory  action under  sections
5(e) and 5(f).   Without these rules, it  would be difficult  for
EPA to conduct adequate reviews within the 90-day, or  at most
180-day, review period.

     In addition, the rules will give notice submitters a clear
understanding of EPA's interpretation of  key provisions of
section 5 and of Agency notice review procedures.  In  doing  so,
they will greatly reduce uncertainty about the scope and  nature
of the Agency's prernanufacture review program.  For example, by
defining such terms as "possession or control" and "importer,"
the rules will indicate who must report and how extensive the
notices must be.  In addition, the notice forms will lighten the
burden for industry in the long run, once submitters have become
familiar with the format and questions.   Companies will not  have
to develop their own formats, and they will know exactly what
information they must supply.  As a result, submitters will  be
able to avoid costly delays due to submitting  insufficient
information.

     Above all, the proposed rules will serve  a fundamental
purpose of TSCA and of section 5 — to protect humans  and the
environment froia unreasonable risks associated with new chemical
substances.   The rules will allow EPA to  conduct prompt reviews
of the hundreds of notices that it will receive every  year,  and
when necessary to take regulatory action  against substances  of
concern before they have harmed humans or the  environment.   The
proposed approach, which will give EPA a  minimum of information
necessary for an adequate review, is the  most  consistent with  the
statute and with the needs of the Agency, the  chemical industry,
and the public.

                        II.  MAJOR ISSUES
A.  Reporting Requirements

     Section 5(a) of TSCA requires manufacturers and importers to
notify EPA 90 days before they manufacture or import a new
chemical substance for a commercial purpose.  In addition, EPA
has proposed that certain processors be subject to section 5
notice requirements (see Section II(I), Processor Notification).

     Section 5(d) of TSCA requires that notices submitted under
5(a) include, insofar as it is known to or reasonably
ascertainable by the submitter, certain information on chemical
identity, use, and exposure listed in section 8(a)(2) and any
test data in the submitter's possession or control.  The
submitter must also include a description of any other data
concerning environmental and health effects known to or
reasonably ascertainable by him.  Section 5 notices, supplemented
by any other information obtained by EPA, form the basis of EPA's
review of new chemical substances.  Therefore, they should
contain enough information for EPA to make a reasoned evaluation
of risks associated with a substance, or to determine that more
information is required for such an evaluation.

     EPA has considered four approaches to implementing section 5
reporting requirements.  The approaches differ in cost to the
submitter and EPA and in level of detail required in a notice.
They are presented below in order of increasing guidance to the
submitter and increasing amount of information that EPA is likely
to receive in the initial notice.  In developing its proposed
approach, EPA sought a process that would permit effective,
consistent review and provide a basis for further regulation,
without unduly burdening either the Agency or the submitter.  For
this reason, EPA prefers Option 3, the October 16 reproposal.

     1.  Options Considered

     Option 1 — "Do Nothing"

     TSCA does not require EPA to issue premanufacturing
notification rules.  EPA could consider section 5 to be self-
implementing and publish no guidelines or rules implementing the
section.  The Act provides some direction on the scope and
applicability of the notice requirements, the information that
must be included in the notices, the length of the notice review
period, and the Agency's authority to regulate new substances.
Under the "do-nothing" option, the argument would be that the Act
is self-explanatory and that its instructions are sufficient to
allow the mandated review.

-------
                               -12-
     Option 2 — Minimum Guidance

     Under Option 2, EPA would provide minimum guidance to
establish general notification procedures and to clarify its
interpretation of major provisions of the Act.  The guidance
would define section 5's applicability to importers, exporters,
and processors; define the content of notices that met
requirements of the statute; and outline procedures for handling
confidential material.  EPA would also specify categories of
information it would require in the notices.  Submitters,
however, would have flexibility in choosing the format and level
of detail of submissions so long as they were consistent with the
Agency's general guidance.  EPA partially adopted this approach
in its Interim Policy, published May 15, 1979 (44 FR 28564).  In
the Economic Impact Analysis, the cost of submitting a notice
under a minimum guidance policy in the long run is estimated to
range from $1,011 to $7.486.

     Option 3 -- Limited Form

     Under this option, EPA would establish notification and
review procedures, and it would require submitters to complete a
limited notice form.  The form would not include all the
information that EPA could require under the Act, but only
information sufficient in most cases for an initial review of a
new chemical substance.  The form, however, would also include a
section of optional questions.  During the review, EPA would
identify substances for more detailed evaluation and possible
regulatory action.  If EPA needed more information from the
submitter or from certain other persons for this detailed
evaluation, it could obtain the information through its proposed
supplemental reporting authority (see Section II(H), Supplemental
Reporting).  Instructions to the form would clarify information
requirements and certain important provisions of the Act.
Submitters could include in their notices additional information
that they thought the Agency should consider in its review.

     EPA proposed a limited form in the October 16, 1979,
reproposal.  Arthur D. Little (ADL) estimated that the costs of
completing the mandatory sections of this form would range from
$1,155 to $8,925.  In commenting on the January 10 proposal, the
Chemical Manufacturers Association (CMA) recommended an even more
limited form.  ADL estimated,that completing the mandatory
sections of the CMA form would cost from $955 to $5,550.

     Option 4 - Detailed Form

     In this approach, proposed January 10, 1979, EPA would
specify notification and review procedures and require the

-------
                               -13-
submission of a form.  In the January 10 form, the Agency
attempts to collect information in sufficient detail for further
regulatory action under sections 5(e) or 5(f).  The detailed form
also contains an optional section.  Under this approach, the
Agency would specify which optional data would be most useful for
its review.  Detailed instructions would accompany the form.  ADL
estimated that the cost to complete mandatory sections of the
January 10 form would range from $3,740 to $22,160.

     The estimated costs of submitting mandatory information
under Options 2, 3, and 4 are summarized in Table II-l.

     2.  Discussion

     If  the Agency adopted Option 1,  it would not publish a
clarification of the Act or regulations to implement section  5.
Each notice submitter would interpret the terms of the Act.
Under this option, the initial burden on  submitters might be  low,
because  they could notify EPA in the  manner  they considered least
costly and most expedient.  Because of the uncertainty associated
with this approach, however, the burden on EPA and industry might
be great in the long run.

-------
                               -14-
     The disadvantages  of  this  approach,  and  of Option 2,  have
become  clear  during  the operation  of  the  premanufacture review
program since  it began  in  July  1979.   The program has  been
operating  under the  Interim  Policy of May 15,  1979.   EPA
recommends  the use of the  reproposed  notice  form,  but  does not
make it mandatory.   Under  this  policy,  EPA has received more than
200 notices.   From these notices,  the Agency  has concluded that
the language  of the  Act by itself  does not provide sufficient
guidance and  that submitters often do not provide known or
reasonably  ascertainable information  necessary for an  adequate
review.  In a  few cases, EPA has returned submissions  as
incomplete, a  time-consuming action for both  the submitter and
the Agency-   The resulting delay may  cost the  submitter his
competitive advantage since  the review period  does not begin
until a complete notice is submitted.   In many other cases,  EPA
has found  it  necessary  to  go back  to  the  submitter for
information that should have been  included in  the initial
notice.  In such cases,  EPA  may have  to extend the 90-day  review
period  under  section 5(c)  to have  enough  time  for an adequate
review.  Even  when requests  for more  information do not lead to
an extension of the  review period,  they require considerable
Agency  and  industry  resources.

     In addition, the uncertainty  that accompanies Option  1
imposes a substantial burden on the submitter.   Without
regulations implementing section 5, industry would have no
guidance on the nature  or  scope of EPA's  premanufacture review
procedures.  Submitters  could learn only  through experience what
data EPA considered  necessary for  its review;  how the  Agency
interpreted key provisions of the  Act;  and when it might seek
additional  information  during the  review  period,  either
voluntarily or under section 8  or  5(e).

     The cost  of Option  1  is difficult  to estimate, because the
information submitted would  depend on the submitter's
interpretation of the requirements of the Act,  and on  the
submitter's estimates about  what information EPA would consider
acceptable. The initial  costs might be  low, but in this case the
likelihood  of  delay  might  be great.   The  cost  of delay,  and of
the general uncertainty  associated with this option, could slow
new chemical innovation.   The economic  well-being  of submitters,
the growth  of  the industry,  and its competitiveness with foreign
industry might be affected.

     To avoid  the problems of Option  1, which  depends  on the
submitter's interpretation of the  Act,  the Agency could publish
minimum guidance,  as in  Option  2.   More appropriate information
might be submitted under this approach, improving  the  quality of
the Agency's review,  reducing the  number  of incomplete notices,
and reducing the number  and  frequency of  EPA requests  for
additional   information.   Reporting guidance for submitters  would
continue to be flexible.   This  approach would  eliminate  some of

-------
                               -15-
the uncertainty under Option.1 and thus reduce delay and other
costs.  In many respects, this approach was adopted in the
Agency's Interim Policy-

     Despite the advantages of this approach, EPA has found that
minimum guidance does not eliminate inconsistent presentation of
data.  Under the Interim Policy, many submitters have chosen to
use the October 16 form, in full or in part.  Where they have
not, the notices are submitted in different formats.  The Agency
must then expend limited resources organizing information for its
review.  These resources would be better spent on the review
itself.  Given the statutory time constraints, the quality of
review may suffer.  Inconsistent format and content also make it
difficult for the Agency to develop a data base, which could be
used in the future analysis of individual substances and in
assessing the program as a whole.

     To reduce the burden on the Agency and to ensure that it
receives the data needed for its review, EPA could develop a
notice form together with an instructions manual.  Options 3 and
4 take this approach.  The forms and instructions would specify
requirements more exactly than minimum narrative guidance could,
and they eliminate much of the uncertainty of the other
options.  Consistent format allows the submitter to establish
information gathering and formatting procedures to minimize
cost.  In addition, EPA has found under the Interim Policy that
the use of the October 16 form expedites and promotes the
consistency of Agency review.  The frequency of delays because of
incomplete submissions is minimized, and additional information
requests during the review period occur less often and are more
focused.

     For these reasons, EPA prefers the use of forms, as in
Options 3 and 4.  Forms can vary in the amount and level of
detail of required information and in the type of optional
material.  In general, the more data the Agency receives, the
higher the quality of its review, but the greater the initial
cost to the submitter.  At the same time, the more detailed the
form, the less likely it is that EPA will have to go back to the
submitter for further information, but the more likely it is that
the submitter will provide EPA with information not needed for
its review.  In developing a form, EPA has attempted to balance
its needs for conducting an adequate review against the burden to
submitters of reporting unnecessary information.

     A notice form could require information sufficient for a
detailed review and possibly for regulatory action under section
5(e) or 5(f), it could require information sufficient for only an
initial screening, or it could simply organize information
explicitly required by the Act.  In January 10, 1979 (Option 4),
EPA took the first of these three approaches; in October 16, 1979
(Option 3), it took the second.

                               -16-
     Proposed January 10 form;  The notice form proposed in
January required information on the identity of the submitter;
and the specific identity of the new chemical substance; and
information on production, use, and human and environmental
exposure.  Submitters were also required to include test data in
their possession or control.  In addition, the form had a lengthy
optional section.

     The costs of filling out the mandatory sections of the
January 10 form were broken down by EPA's economic contractor,
Arthur D. Little.  These costs, excluding costs of asserting and
substantiating confidentiality, are given in Table II-2.

                               -17-
     Many industry commenters suggested that the January  10  form
was excessive in scope and in level of detail.  They  argued  that
much of the data required in the  form would not be  available at
the time of submission, that the  cost of developing data  would
impose an unreasonable burdeji on  submitters, and that EPA lacked
the statutory authority to require much of the information in the
form.  Several industry commenters submitted alternative  forms,
which generally reflected a narrower interpretation of  EPA's
statutory authority and its data  needs.  CMA, for example,
recommended a form that reduced both the scope and  the  level of
detail.  Among other changes, the CMA form made optional
questions concerning workplace concentrations, manufacturing
process information, rates and amounts of release,  and  consumer
exposure.

     Proposed October 16 form;  In response to these  comments,
EPA proposed a revised form on October 16 (Option 3), in  which it
reduced the data requirements of  the January 10 form.   These
reductions do not reflect a determination by EPA that it  lacks
statutory authority to require additional information.  Rather,
they reflect two major objectives:  (1} To obtain adequate
information to permit at least a  preliminary assessment of the
risks associated with the manufacture, processing,  distribution
in commerce, use, and disposal of a new chemical substance,  and
(2) To achieve this objective at  a minimum cost to  persons
submitting notices.  In revising  the notice form, EPA considered
the minimum information and level gf detail necessary for a
preliminary assessment, the likely'availability of  such
information, and the associated costs.

     Arthur D. Little estimates for completing the  mandatory
sections of the October 16 form,  not including costs  of asserting
and substantiating confidentiality, are given in Table  II-3.

     This revision reduced the cost of the January  10 proposed
form by 50-60%, significantly lessening the burden  on industry
although still providing EPA with sufficient information  to  make
an initial screening of new chemical 'substances.  In  the  October
reproposal, EPA rejected the minimum information form recommended
by CMA.  This form further reduces the cost of reporting  by  20-
30%, but it does not provide information in areas critical to
EPA's evaluation of new chemical  substances.

     Comparison of information required by forms;  Information on
manufacturing processes can be used to illustrate the different
levels of detail in the various forms, and to explain the
differences in cost.  The January 10 proposed form required the
submitter to provide a detailed schematic flow diagram
illustrating each manufacturing and processing operation he
intended to conduct (Part I, Section E).  According to ADL
(Impact of TSCA Proposed Premanufacturing Notification

-------
                               -19-
Requirements, p. V-10), this diagram would  require 4-40  technical
hours ($100-$!,000) to prepare, plus 2-8 clerical hours  and  2-4
legal and managerial hours.  In the reproposal,  in an  effort to
simplify the form and reduce the  reporting  burden, EPA deleted
several specific requirements.  The revised form does  not  require
description of the type of process equipment,  the components of
each process stream, and process  parameters.   Rather,  it requires
a simplified block diagram (Part  2, Section A, Subsection  2)  that
provides a basic understanding of the manufacturing process
necessary to identify potential exposures.   According  to ADL,
this abbreviated diagram would require  1-24 technical  hours  ($25-
$600) to complete, plus several clerical and managerial  hours
(Estimated Costs for Preparation  and Submission  of Reproposed
Premanufacture Form, p. 34).

     The block diagram as proposed in October  considerably
reduces the burden on the submitter.  EPA,  however, believes  that
it cannot eliminate a mandatory block diagram  entirely,  as the
CMA form does.  In its review of  notices under the Interim
Policy, EPA has found the block diagram necessary to make
qualitative estimates of potential workplace exposure; to  make
quantitative estimates of the amount of new chemicals  and
byproducts released; to validate  estimates  provided in other
parts of the form; and to provide supplemental information where
no data are provided in other parts of  the  form  (for example, on
composition of release streams or the amount released  to the
environment).  Under the Interim  Policy, when  EPA has  not
received a block diagram in a notice, Agency reviewers have  in
most cases found it necessary to  draw one themselves on  the  basis
of 1- to 2-hour telephone conversations with the submitter.   In
most of these cases, the necessary information was readily
available to the submitter.  It clearly would  have been  more
efficient and less expensive if the submitter had provided the
diagram in the first place.

     In other ways, the information requirements of the  January
10, the October 16, and the CMA form bear essentially  the  same
relationship.  The January 10 form, for example, requires
specific estimates of the magnitude, duration, and frequency of
worker exposure.  The revised form requires significantly  less
detailed estimates and provides ranges  for  reporting workplace
concentrations.  The CMA form makes all information on workplace
concentrations optional.  In the  same way,  the January 10
proposed form requires specific estimates of environmental
release data, including stack parameters, concentrations,  and
daily and hourly discharge rates.  The  October 16 proposed form
requires only total release estimates.  The CMA  form confines
quantitative release estimates to an optional  section.

-------
                               -20-
     In all these areas, EPA reduced the reporting burden  in the
January proposal without seriously reducing  its  ability  to make
an initial assessment of the risks associated with new chemical
substances.  In cases where EPA needs additional information for
a more complete assessment of risk, the Agency would  require
supplemental reporting.  However, to reduce  the  requirements
further, as in the CMA  form, would severely  restrict  EPA's
ability to make even an initial assessment and would  lead  to
frequent requests for further information.

     One major cost in both the January 10 and the October 16
proposed forms is the retrieval, organization, and attachment of
health and safety data.  ADL estimated that  providing health and
safety data in the January form would cost from  $900  to  $4,800.
In the October reproposal, EPA significantly reduced  this  cost by
eliminating specific questions on evaluations and assessments of
test data in the section on physical and chemical properties and
health and environmental effects (Part II, Section A).   In its
place, the form requires submitters to attach this information
with the notice.  The cost of submitting these attachments,  would
range from $450 to $2,000, according to ADL  estimates.

     In reducing the cost of providing health and safety data,
the revised form has not changed in any way  the  basic requirement
in section 5(d)(l)(B) of TSCA that the submitter include in the
notice all health and safety data in his possession or control.
Because of the statutory requirement to submit these  data,  any
reporting scheme would  involve these costs.  The October
reproposal, in fact, reduces the costs of retrieval,
organization, and submission of health and safety data to  a
minimum.  Because of this, the costs of providing health and
safety data under Option 3 are no greater to the submitter than
those of Option 1 or 2.

     3.   Preferred Approach

     EPA's preferred approach is Option 3, the "limited  form"
option,  using the October' 16 reproposed form.  This form will
supply information necessary for a preliminary assessment  of
risks associated with most new chemical substances.   The cost of
completing the form will not be substantially greater than
supplying information under Option 2, and costs  will  decrease as
submitters become more  familiar with the form.   Although
innovation might be slowed initially, long-run costs  will  be
minimized once procedures for reporting have been established.
The increased certainty about what data must be  submitted  will
mean fewer delays,  fewer and more specific supplemental  data
requests,  and more efficient Agency review.  EPA's burden  will be
minimized by established review procedures;  more complete  and
consistent review will result.

-------
                               -21-
     Option 3, with the October 16 reproposed form, balances the
cost of compliance for industry with EPA's need for detailed
analysis.  A limited form with guidance is sufficient for an
initial screen of new chemical substances, and it reduces the
burden on the industry by concentrating on those chemicals that
clearly warrant further regulation.  Only if EPA needs additional
data will the expense of obtaining it be incurred.  The use of a
limited form is the most cost-effective approach to achieving
Congress's goal of protecting the public from risks associated
with new chemical substances without unduly impeding or creating
unnecessary economic barriers to technological innovation.

B.   Confidentiality

     The confidentiality of information submitted to EPA is one
of the most controversial issues associated with this
rulemaking.  EPA, mindful of both public and industry interests
as well as procedures that would unnecessarily burden the Agency,
has proposed a category approach to confidentiality.  In this
approach, submitters would assert and substantiate claims of
confidentiality by linking the information claimed confidential
to certain categories of information established by EPA.  The
disclosure policy regarding chemical identity as part of health
and safety studies reflects this attempt at balancing conflicting
interests as well.  The following section discusses various
approaches EPA considered to accomplish the goals of public
disclosure and protection of traditional trade secret
information.

     1.  Mechanics

     The mechanics of confidentiality are the procedures for
asserting and substantiating claims of confidentiality.  EPA
considered three options -- Option 1, the January 10 proposal;
Option 2, the October 16 reproposal; and Option 3, the approach
of the Interim Policy of May 15, 1979.  The Agency has stated
that, under any of the options, documentation submitted to
substantiate confidentiality claims may be treated as
confidential business information.

     Option 1 — January 10 Proposal

     Submitters claim each confidential item individually by
checking a box adjacent to the entry on the form.  Submitters can
also claim information confidential in attachments to the form.
They would do this by designating the information as confidential
on the attachment and providing a copy of the attachment with the
information claimed confidential deleted so that this copy could
be placed in the public file.

-------
                               -22-
     Submitters would substantiate claims of confidentiality for
chemical identity and health and safety study information by
answering two series of questions.  Other information claimed
confidential in the notice would be substantiated by the
submitter when requested by the Agency.

     Option 2 — October 16 Reproposal

     In the October 16 reproposal, submitters could assert claims
of confidentiality by category.  Submitters would assign items to
the categories provided by the Agency by answering questions that
explained the reason for including this information in the
category.  Substantiation Would be by category of information as
well; submitters could substantiate most claims by signing a
certification statement on the form.  However, they would have to
substantiate chemical identity and information that did not fall
within the categories provided by the Agency by responding to a
series of questions.

     Option 3 — Minimum Guidance

     Under Option 3, the submitter asserts his claims of
confidentiality by clearly identifying confidential business
information in the notice.  Substantiations would not have to be
submitted with the notice.  Where EPA required substantiation, it
would ask the submitter by letter a series of questions on each
category of information claimed confidential.  The submitter
would substantiate the claims by responding to the questions
within 15 days.

     Discussion and Preferred Option

     Although there are many variations of these options,
described in Part II of the Economic Impact Analysis,  these three
options represent the basic choices available to the Agency.

     In the October 16 reproposal, EPA explained that revision of
the January 10 proposal was based on Agency experience with
notices submitted under the Interim Policy, comments received on
the January 10 proposal, the frequency of Freedom of Information
Act (FOIA) requests, the need for Agency review of
confidentiality claims, and Agency consideration of public and
private interests in disclosure.  The Act itself, in section 14,
indicates a Congressional emphasis on disclosure of health and
safety data and nondisclosure of traditional trade secret
information.  The category and substantiation scheme reflects
this Congressional intent by placing a light burden on industry
to claim and substantiate information of a commercial nature
while requiring a more detailed substantiation for information
relevant to health and safety information.

-------
                               -23-
     As noted in the Economic Impact Analysis  (p. 126), the  total
amount of information required under the January and October
approaches does not differ significantly.  However, the January
10 proposal requires the submitters to expend  greater effort in
substantiating a claim, because they generally must answer more
substantiation questions; the October 16 reproposal with  its
category and linkage approach, requires greater effort in
asserting a claim.  EPA prefers the second approach because  it
focuses the submitter's attention on the relationship among  his
confidentiality claims, which may make it unnecessary for him to
make as many claims to protect his proprietary interests.  Option
2 also provides a basis for a less duplicative substantiation.
In Option 2, the Agency designated categories  of information
based on the information most commonly claimed as confidential
since the premanufacture program began.  For information  that EPA
has included in a category, the submitter may  assert his  claim by
marking a single box X rather than by searching through the  forms
and individually marking every piece of related information  to be
claimed confidential.  If the information has  not been included
in the category by EPA, the submitter marks the item separately
and explains how its disclosure would reveal confidential
business information.

     By using the category approach, Option 2  significantly
reduces the information required for substantiation and allows
the submitter to avoid duplication. Also, under Option 2  EPA will
review all substantiations for items in a notice at one time.
Under Option 1, EPA might receive requests for different
information in the same notice at different times.  This  would
necessitate several reviews of the same notice by EPA.

     The different degrees of burden for substantiation reflect
different balances between the interest of industry in protecting
proprietary information and the public's interest in protecting
itself and in effectively participating in the review process.
Option 2 would eliminate the need for submitters to supply
additional substantiation information to the Agency, which would
reduce costs and time delays.  This approach is also intended to
lessen the submitters' uncertainty as to the kind of
substantiation the Agency would find acceptable and upon  which it
would make a determination not to release data claimed
confidential.  The unstructured approach of the January 10
proposal (Option 1) may seem to involve lower  initial costs, but
the increased cost due to submitter's uncertainty about Agency
standards, the need for repeated Agency contact to determine the
basis of the submitter's claims, and the submitter's need to
provide additional information all increase these initial
costs.   Therefore, EPA prefers Option 2, the October 16 proposal.

-------
                               -24-
     2.  Timing of Substantiation

     Whichever format was provided for asserting and
suostantiating claims ot confidentiality, the Agency would also
nave to decide when to require the substantiation.  EPA has
considered three approaches to this issue.

     Option 1 — January 10 Proposal

     The January 10 proposal requires that submitters
substantiate health and safety study information and chemical
identity with the notice.  Other items can be substantiated when
EPA requests it, although EPA encourages submitters to
substantiate all claims of confidentiality when the notice is
submitted.

     Option 2 — Section 5(d}(2) Notice Option

     This option requires substantiation of claims of
confidentiality for chemical identity, categories of use, and
test data at the time the notice is submitted.  EPA, therefore,
would know whether the information could be published in the
5(d)(2) notice.  Other information, if claimed confidential,
would have to be substantiated if requested,  although again EPA
encourages substantiation with the notice.

     Option 3 — October 16 Reproposal

     Tne reproposal requires substantiation of all information
claimed confidential when the notice is suomitted.

     Discussion and Preferred Option

     The preferred scheme,  Option 3,  places emphasis on the
timely release of data necessary for public oversight while
safeguarding traditional trade secret data.  As the proposed
Economic Impact Analysis states, substantiating all types of
information claimed confidential in the notice at the time of
submission by the October procedures (Option 3) is less costly to
the submitter than narrative substantiation under the other
options. Not only is Option 3 less costly to the industry, but it
provides many benefits to the Agency as well as the public.  It
allows the Agency to review all claims at once and to see the
pattern and rationale behind confidentiality claims, giving the
Agency insight into the needs of the chemical industry.  It
eliminates the need for multiple requests for information and
provides clear guidance to industry regarding Agency standards
for disclosure of nonconfidential information.  The short notice
review period provided by section 5 and the interest Congress

-------
                               -25-
displayed in public participation in the review process dictate
an approach that will allow the Agency to review claims of
confidentiality in a timely manner.  Without substantiation in
the notice, the Agency would never be in a position to release
nonconfidential data to the public so that it could participate
in the notice review process.  Finally, the Agency needs
substantiation information at submission to reply promptly to
Freedom of Information Act (FOIA) requests.  Commenters on the
October 16 reproposal suggested that FOIA requests would be
infrequent, and therefore early substantiation would be
unnecessary.  In fact, since the premanufacture review program
began in July 1979, public interest groups have regularly made
FOIA requests for notices.  For all these reasons, therefore, EPA
proposed substantiation at the time the notice is submitted.

     3.  Generic Information

     If submitters claim information of particular public
interest as confidential, the Agency has proposed that "generic"
or masked information be provided to the public so that at least
some information is available.  Some of the Agency's earliest
section 5(d)(2) notices were totally devoid of information, which
made public participation in review of those notices
impossible.  The following options have been considered:

     Option 1 — January 10 Proposal

     The January 10 proposal required submitters t,o develop a
generic name for chemical identity according to Agency
instructions.  If categories of use were claimed confidential,
generic descriptions of that information would also be
required.  EPA did not give specific guidance about an acceptable
generic or masked category of use description.

     Option 2 — October 16 Reproposal

     Procedures for developing four types of masked information
are provided in the reproposal:  manufacturer's identity,
categories of use, chemical identity, and physical and chemical
properties.  If these procedures do not provide adequate
protection for information claimed confidential by the submitter,
the submitter may provide alternative masked information suitable
for public disclosure either in the FEDERAL REGISTER or in the
public docket.

     Option 3 — No Masked Data

     Under this option, EPA would not require generic substitutes
for confidential data.  No masked data would be published  in  the
FEDERAL REGISTER or placed in the public docket.

-------
                               -26-
     Discussion and Preferred Option

     Section 5(d)(2) of TSCA lists certain information that EPA
must publish in the FEDERAL REGISTER 5 days after receipt of a
premanufacture notice.  It is clear that the purpose of this
notice is to inform the public that a notice on a new chemical
substance has been submitted for review and that the public
should come forward with any information it has about the
substance and participate in Agency review.

     Option 3 does not provide adequate notice to the public.
Option 1, as noted in the comments to the January 10 proposal,
does not give sufficient guidance as to categories of use
information, nor does it give the submitter the flexibility to
provide generic information unique to his confidential business
needs.  Option 2 provides sufficient information for the initial
notice to the public while recognizing the industry1s need to
protect confidential information.  As the proposed Economic
Impact Analysis notes, Option 2, with clear guidance as to what
generic descriptions will meet Agency standards, is the most
effective approach for reducing industry uncertainty and concerns
about any arbitrariness in the Agency's treatment of generic or
masked information.

     4.  Disclosure of Chemical Identity

     The Agency1s January 10 proposal included an approach for
disclosing chemical identity that has been claimed confidential.
As the Agency noted on January 10, chemical identity is
underlying data to a health and safety study.  However, EPA
recognizes the special significance this information may have,
especially during the early stages of development of the new
chemical substance.  EPA considered three options regarding
timing of disclosure of chemical identity.  Consistent with
section 14(b), under all the options EPA would not disclose
chemical identity if it revealed confidential process information
or proportions of a mixture.

     Option 1 -- Disclosure at the time of notice submission

     Under this option, chemical identity would be published in
the section 5(d)(2) notice announcing receipt of the
premanufacture notice, and health and safety data would be made
available to the public.  At commencement of manufacture, the
chemical identity would be entered on the Inventory and would  not
be masked by a generic name.

     Option 2 — January 10 Proposal

     Because of the special importance of chemical  identity, the
January 10 proposal provided that it would not be disclosed until
commencement of manufacture.  The chemical identity would go on
the Inventory at commencement of manufacture and would not be
masked by a generic name.

-------
                               -27-
     Option 3 — Disclosure at Distribution in Commerce

     Several commenters suggested that chemical identity should
not be disclosed until distribution, which would be sometime
after manufacture for a commercial purpose.  Under this approach,
a generic identity would be initially entered on the Inventory;
after distribution began, the chemical identity would go on the
Inventory.

     Discussion and Preferred Option

     Section 14(b) provides that data from health and safety
studies may be disclosed to the public notwithstanding the non-
disclosure provisions of section 14(a).  The legislative history
and scientific practice argue that chemical identity is part of a
health and safety study; as such it should be disclosed.
However, section 14(a) also indicates the concern for protection
of proprietary data.  Therefore, the Agency prefers a compromise
position that would prevent disclosure during the early stages of
development and commercialization, and that would protect
confidential chemical identity until the time of manufacture or
some reasonable time thereafter.  The January 10 proposal (Option
2) provides an approach that is consistent with this policy.
This approach limits access to data that the public would have
under Option 1, but the Agency hopes to reduce the effect of this
limitation by providing meaningful generic information indicating
the toxicologically significant aspects of the molecular
structure of the chemical identity claimed confidential.

     Option 3 has some of the advantages of Option 2, but it
creates uncertainty because the "commencement of commercial
distribution" is difficult to define, and it would require
submitters to notify EPA when they first distributed a substance
commercially as well as at commencement of manufacture.  To
eliminate these difficulties, EPA is considering the possibility
of protecting the confidentiality of chemical identity underlying
a health and safety study for a set time after commencement of
manufacture — for example,  six months — by which time the
manufacturer would have had adequate time to begin commercial
distribution.  With this modification, the submitter would not
have to notify EPA at commercial distribution.  This approach,
however, would still have some disadvantages of Option 3.  EPA
would have to conduct an additional review of confidentiality
claims when the substance was first distributed commercially to
determine if disclosure of chemical identity would reveal
confidential processes or proportions of a mixture.  This
approach also postpones the public's access to these data to a
point at which it may be less likely to prevent exposure or
distribution of the new chemical substance.  EPA solicits public
comment on the appropriateness of this approach as an alternative
to the January 10 proposal.

-------
                               -28-
C.   Incomplete Submissions

     A prernanufacture notice must meet certain explicit
standards.  If the submission does not meet these standards, it
is incomplete and the 90-day review period will not start.
Section 720.34 of the January 10 proposal explained EPA's
interpretation of section 5 notice standards, classified various
types of deficiencies, and described the procedures EPA will
follow in handling deficient notices.  The proposed criteria for
defining incomplete submissions are drawn either directly from
TSCA or from other parts of the proposed premanufacture
notification rules.

     In developing its approach to incomplete submissions, EPA
has considered the four options discussed below.

     1.  Options Considered

     Option 1 — January 10 Proposal

     In section 720^34 of the January 10 proposal, EPA identified
two kinds of deficiencies:  (1)  Major deficiencies that prevent
the review period from starting; (2) Minor deficiencies or errors
that stop the clock during the notice period.  The distinction
between major and minor deficiencies is determined by certain
criteria set out in the proposal.  If EPA identifies a major
deficiency in a submission at any time during the review period
— such as failure to supply information required in the notice
form if it is known to or reasonably ascertainable by the
submitter — the Agency may return the submission.  In this case,
EPA would consider no notice to have been submitted.   When a
submission was received that did meet the criteria, the 90-day
review period would begin.

     If EPA identifies a minor deficiency, within 30 days after
receipt of a submission it may request a submitter to correct the
deficiency.  Examples of minor deficiencies are failure to date
the notice or a typographical error that renders an entry" unclear
or ambiguous.  The Agency will suspend the review period until
the submission is corrected. If the submitter does not make the
correction within 30 days, EPA may determine that the submission
does not meet the standards of the Act.  Also, if EPA discovers
during or after the review period that the submitter provided
false or misleading information, EPA can treat the submitter as
not having complied with the notice requirements of section 5.
Therefore any manufacture or import may be in violation of TSCA
and subject to penalities of sections  15 and 16.

-------
                               -29-
     Option 2 — Appeal Procedures

     Option 2, a modification of Option 1 reflecting concerns
expressed by industry, narrows EPA's criteria for determining
that a submission does not meet the standards of the Act.  Under
this option, EPA would notify the submitter within 30 days of
receipt of a submission if it was incomplete (major deficiency),
or if it contained errors (minor deficiency). If the submission
was incomplete, the notice review period would not begin until
the deficiencies were remedied.  Submitters could appeal an EPA
finding that a submission did not meet the Act's requirements.
For errors, the review would not stop, although submitters would
be encouraged to correct the errors.

     Option 3 — Case-by-Case Approach

     Taking a case-by-case approach, EPA could find a submission
insufficient to fulfill the requirements of section 5.  However,
no formal criteria or procedures would govern EPA's treatment of
such submissions.  If EPA found a submission incomplete, the
review period would not start, and the submitter would not have
any formal avenues of appeal.  For errors in the submissions
(e.g., typographical mistakes), EPA would take the same action as
in Option 2.

     Option 4 — No Incomplete Submission Provisions

     Under this option, if the submitter did not file a notice
that met the Act's standards, EPA could require information under
the proposed supplemental reporting authority. Commenters on the
January 10 proposal also suggested that EPA could control the
substance under section 5(e) pending the submission of the
necessary information.

     2.  Discussion

     Options 1 and 2 outline the criteria that EPA uses in
determining whether a submission meets the statutory
requirements. Notices must fulfill these criteria when submitted,
or be corrected in a timely manner, before the review period
begins. Under Option 3, submitters would also have a strong
incentive to submit notices that meet the requirements of the
Act, although they would not have clear guidelines about how EPA
interpreted these requirements.  The incentive of submitters to
correct major deficiencies would be the same as in Options 1
and 2.  Under Option 4, EPA could only request that deficient
submissions be corrected.  If submitters did not respond, EPA
could use its proposed supplemental reporting authority or, in
some cases, issue a section 5(e) order requiring additional
data.   However, these actions would expend considerable EPA
resources, and the notice review period might be interrupted or
extended.

-------
                               -30-
     Submissions in Options 3 and 4 are not held up to explicit
criteria, and no clear distinction is made between major
omissions and errors.  In Option 4, there would be no guidance
for submitters who must correct their notices.  Without published
criteria and procedures, industry would be uncertain about how
submissions would be treated, and the possibility of
inconsistency in Agency actions would increase.

     Option 4 presents several special problems.  If a person
failed to submit a complete notice, EPA would accept the
submission for review.  However, to obtain the necessary
information, the Agency might extend the notice period up to 90
additional days under section 5(c), issue a section 8(a)
supplemental reporting requirement, or, in some cases, issue a
section 5(e) order.  Delays associated with these actions might
have an adverse effect on the submitter's production schedule and
marketing plans.

     All four options will involve out-of-pocket expenses to
prepare notices.  The submitter would incur additional expenses
under Options 3 and 4 if EPA required supplemental reporting or
otherwise took action to get information.  Option 2 carries an
additional cost if submitters appeal an EPA decision that
submissions do not meet statutory requirements; however, the
right to appeal protects them from arbitrary action.

     EPA's initial costs under Options 1, 2, and 3 are greater
than under Option 4 because under these options the Agency must
review notices for compliance.  Option 3 perhaps involves the
greatest initial cost for EPA because the Agency will have to
handle notices on a case-by-case basis without formal criteria.
Option 4 would at first involve the fewest EPA resources.  But,
potentially, it could be the most expensive for both EPA and
industry, if EPA frequently used the supplemental reporting
authority or otherwise took action to get information that should
have been included in the initial submission.

     Costs to society are highest with Options 3 and 4.  EPA may
not have enough resources to review and take action against
incomplete submissions on a case-by-case basis.  Therefore, under
Option 3 the Agency may miss deficiencies in certain submissions,
and therefore fail to learn of important information on
potentially hazardous chemicals.  In Option 4, submitters who
fail to provide complete submissions might be subject to
supplemental reporting rules or other action.  However, EPA would
be able to take relatively few of these actions.  Thus, the
Agency may pass over some problem chemicals for which deficient
submissions are made; the public and the environment would
suffer.  Because Options 1 and 2 impose standards on submitters

-------
                               -31-
and commit EPA to reviewing section 5 notices  for  deficiencies,
there is less chance that EPA will be unable to  gather  adequate
information to evaluate potentially harmful chemical  substances.

     3.  Preferred Option

     EPA prefers an approach that sets out the criteria that
submissions must meet for the notice review process to  begin.
Submitters, therefore, know the requirements,  and  the costs of
preparing complete notices are well defined.   Submitters will
also know the delay likely to result from submitting  information
that does not meet the requirements.  As explained earlier, costs
to EPA are likely to be lower under options that set  out clear
standards for notices.

     Options 1 and 2 incorporate the statutory requirements that
a notice include certain information.  A submitter is not  in
compliance with this section if his submission does not contain
that information, as long as it is known to or reasonably
ascertainable by him.  An incomplete submission prevents EPA from
conducting a proper assessment.  Option 3 does not provide clear
guidelines, and Option 4 does not provide any procedures to act
on incomplete submissions.  In this case, the content of notices
would depend on industry's interpretation of the statute.  EPA
does not believe that Congress intended industry to make its own
interpretations of the Act.  Moreover, TSCA requires  the
submitter to provide the information specified; it does not place
the burden on EPA to extract it.

     Option 1 and Option 2 are similar, but Option 1 places the
burden on the submitter, not EPA, to correct the submitter's
errors in notices.  Under Option 1 EPA can stop the review clock
until the submitter corrects "minor deficiencies"  affecting the
clarity of the notice.  This should not be burdensome to the
submitter, because the deficiencies would be minor — like a
failure to date the notice — and therefore easy to correct.
EPA, of course, will not require the submitter to  correct  every
error, but only those that make the notice unclear.   Under Option
2, EPA would notify the submitter of the error within 30 days,
but the review clock would not stop.  The submitter would have
less incentive to correct the error promptly.  As  a result, the
burden for interpreting any ambiguity caused by the error would
fall on EPA.  Finally, the purpose of EPA's data-gathering
authority under sections 8 and 5(e) is not to gather  information
necessary for an initial screen, but to require additional data
based on the information initially provided.

     Option 2,  however,  provides significant benefits for
submitters.  Under this option, EPA must notify submitters of a
deficiency within 30 days of receipt of a submission.   Therefore,
submitters would know quickly if their notices met the  minimum

-------
                               -32-
standards of the Act, and they would not be faced with the
possibility that EPA could stop the review period after that
time.  Also, submitters could appeal an EPA finding that a
submission did not meet the standards of the Act.  EPA requests
comments on this approach and other approaches to determine that
submissions meet the requirements to begin the notice review
period.

D.   Customer Contact

     Section 5 must contain certain information on processing and
uses that is known to or reasonably ascertainable by the
submitters.  In some cases, submitters may not know about
proposed methods of processing or uses, but this information is
generally known to their customers.  To get this information for
a notice, submitters may have to contact potential customers.

     EPA considered four options for defining the extent of the
submitters' obligation to contact and gather information from
customers.

     1.  Options Considered

     Option 1 -- Provide Information from All Potential Customers

     Option 1, section 720.20(e) of the January 10, 1979,
proposal, requires notice submitters to contact persons who they
have reason to believe would purchase the new chemical
substance.  Submitters must ask potential customers to complete a
Processing and Consumer Use Form.  The Form requests information
on exposure and environmental release resulting from processing,
use, and disposal.  In addition, submitters must list in their
notices the names and addresses of the customers they contacted,
and they must identify the persons who provided them information
or who were sending it directly to EPA.  Customers may claim any
information they provide confidential.

     Customers are under no legal obligation to respond to the
submitter's request for information.  When customers do not
respond promptly,  or when they do not respond at all, EPA does
not expect submitters to delay sending their section 5 notices.
Failure of customers to provide information either to the
submitter or to EPA does not affect the beginning of the notice
review period.

     Two exceptions apply to these mandatory customer contact
requirements.   Submitters may contact a sample of customers if
they believe that a significant number of customers will provide
duplicative information.  And submitters need not contact any
person who they believe will not provide substantive information
required in the notice form.

-------
                               -33-
     Option 2 — Report Number of Persons with Firm
     Commitment to Purchase Substance for Unknown Uses
     and Volume of Substance to be Sold to These Persons

     Option 2 was discussed in the October 16 reproposal as an
alternative to Option 1.  Option 2 has no mandatory customer
contact provision, no customer list, and no Processing and
Consumer Use Form.  Instead, submitters are required only to
report the number of committed customers intending to use the
substance in ways not known to them and to report the percentage
of production volume allocated to those customers during the
first three years of production.  The customer definition is
narrowed from that of Option 1 to persons who have contracted to
purchase, submitted a purchase order for, or made a firm
commitment to purchase the new chemical substance for uses
unknown to the submitter.

     Under this option, if EPA needs additional use information,
it can go back to the submitter for the names and addresses of
the customers.  EPA. can then contact the customers.  These
contacts will be limited to situations where EPA needs
information for a detailed assessment.

     Option 3 — Provide Information in Option 2 Plus a
     Customer List

     Option 3 is Option 2 with a customer list added.  It was
also discussed in the October 16 reproposal as an alternative to
Option 1.  Submitters must include with their notices a list of
customers who have contracted to purchase, submitted a purchase
order for, or made a firm commitment to purchase the new chemical
substance.  EPA may contact prospective customers directly when
it finds that use information or other information in the section
5 notice is not adequate to assess potential exposure.

     Option 4 — No Mandatory Customer Contact

     Option 4 eliminates the customer contact provisions.
Submitters are under no obligation to send a customer list to
EPA,  or to ask customers to submit information on uses of the
chemical substance.  However, submitters still are required to
complete section B of the reproposed form, "Industrial Sites
Controlled by Others."  In this option, as in Options 2 and 3,
EPA,  not the submitter, will obtain customer use information when
it is needed for detailed review.

                               -34-
     2.  Discussion

     Option 1 is the most costly option  for  submitters.   The
comprehensive definition of customers, which includes  potential
customers as well as those who have made  a firm  commitment  to
purchase, will require submitters to keep up-to-date  files  on
committed customers and customer contacts.   Many companies  may
not ordinarily keep such records.  Thus,  submitters may  incur
additional expenses to have this information on  hand.  Submitters
will also incur costs to contact customers.

     Submitters in Option 2 and 3 will also  incur certain
administrative costs, but these costs will be less than  in
Option 1.  With the customer definition narrowed to committed
customers, these options should not in most  cases increase
recordkeeping costs for submitter.  Generally, the customer
information requested in Options 2 and 3  is  in a company's
records.  Submitters will only have to prepare and submit this
information.  (Under Option 3, submitters may incur the  cost of
preparing a customer list.)  Under Option 4,  submitters  have no
obligation to submit customer information, and therefore will
incur no costs associated with mandatory  customer contact.
Because there is no Processing and Consumer  Use  Form in  Options
2, 3, and 4, submitters will not incur the costs of contacting
customers.  Instead, EPA will incur these costs.

     Option 2 is less expensive to submitters than Option 3
because it requires them to give EPA the  names and addresses of
customers only when the Agency needs to contact  them for use
information — which EPA may require for  chemicals subject  to
detailed review.  Since only a small percentage  of new substances
undergo detailed review, submitters in most  cases under  Option 2
will not have to provide EPA with a customer list.  Under Option
3, however, submitters are required in every case to send a
customer list with their section 5 notice.   Therefore, they may
incur the expense of providing EPA information unnecessary  for
its review.

     Although Option 4 does not require submitters to  contact
customers or to submit customer information,  submitters  may still
incur expenses associated with customer information.   Under this
option, EPA will have to go to submitters for customer
information needed for its review.  Some  submitters may  provide
EPA with this information voluntarily.  In other cases,  EPA may
have to take action under the proposed section 8(a) supplemental
reporting authority to get information from  either the submitter
or processors.

-------
                               -35-
     Option 1, which requires customer contact, should eliminate
delays when customers voluntarily submit the Processing and
Consumer Use Form.  Under Options 2, 3 and 4, EPA will have to
get use information from customers, possibly leading to delays in
the review process that may affect the introduction of new
chemicals into commerce.  Delay is more likely in Options 2 and 4
than in 3, because in these options EPA must go first to the
submitter to get the names of customers before it contacts
them.  This will not be necessary in Option 3 because the
submitter is required to provide a customer list.  If a submitter
or customer is reluctant to provide EPA with information, the
action EPA takes to obtain this information may make it necessary
to extend the review period under section 5(c).

     Initial costs to customers are likely to be greatest under
Option 1, because in most cases they will be asked to complete a
Processor and Customer Use Form.  On the other hand, delays are
likely to occur less often under this option.  Under Options 2,
3, and 4, EPA will request customer information only on chemicals
undergoing detailed review.  Customers in the no-mandatory-
contact options, therefore, will not in every case incur costs to
provide EPA with use information.

     Customers face the risk of trade secret disclosure when they
provide use information to the submitter (Option 1) or to EPA
(Options 2, 3, and 4)-  This threat to confidentiality may affect
customers' responsiveness, especially if Option 1 is adopted.
The fear of disclosure of the customer lists in Options 1 and 3
may also affect customers' responsiveness.

     Administrative costs to EPA and the likely extent of its
efforts to obtain customer information must be considered in an
evaluation of the options.  Option 1 requires the least effort,
because the submitter is responsible for contacting customers.
But Option 1 may involve the highest administrative costs for EPA
because the Agency must file, maintain, and protect the
confidentiality of customer information on a routine basis,
although it may need this information for only a small percentage
of chemicals.  In Options 2, 3, and 4, EPA will incur lower
recordkeeping costs.  The cost is highest for Option 3, where
submitters are required to include customer lists with their
section 5 notices.

     The potential costs to society are greatest under Option 4.
Because it will receive less customer information, EPA will be
less able to protect health and the environment from the
introduction of hazardous substances.  Despite their differences,
Options 1, 2, and 3 each give EPA the means to identify customers
and to gather enough information to decide if detailed review is
necessary.  In this regard they afford greater protection to
society than does Option 4.

-------
                               -36-
      3.  Preferred Option

      EPA prefers Option 2.  Customer  use  information is  usually
necessary only  for detailed review.   Because EPA  expects a  small
percentage of chemicals to undergo detailed review,  it does not
believe it is necessary to collect this information  routinely,  as
would be done in Option 1.  EPA also  believes  that it does  not
routinely require a customer  list, which  Option 3 provides.
However, EPA does need enough customer information to determine
whether processing and use is likely  to cause  a problem,  or
whether more information is needed.   Option 3  would  generally
provide EPA with this information in  the  initial  notice;  Option 4
often would not.

      EPA believes the information required from submitters  under
Option 2 gives  the Agency adequate information for its initial
review of new chemical substances.  It would give EPA an
understanding of how complete the use information is  in  the
notice.  In combination with other information in the notice, the
customer information under Option 2 will  help  EPA decide whether
or not to ask for additional use information from the submitters'
potential customers.  If EPA determines that it needs additional
information, it can contact submitters and ask them  to provide
the names and addresses of their customers.

      Option 2 is less burdensome to industry than Options 1 and
3.  In Option 2, EPA will request more information only  when it
is necessary for detailed review, and the Agency  will generally
carry the burden of contacting the customer.   Thus,  submitters,
their customers, and EPA would not be responsible for routinely
gathering and maintaining information that is  usually not
necessary in the initial evaluation of a  chemical substance.
Also, EPA would not have to maintain  files and protect the
confidentiality of unused information, as it would under Option 1
and to a lesser degree under Option 3.

E.  Importer Definition

     Section 3(7) of TSGA defines "manufacture" to include
"import."  Therefore,  importers are subject to all requirements
of the Act that apply to manufacturers, including the notice
requirements of section 5.   In developing a proposed  definition
of importer for the purposes of section 5, EPA took  into account
the fact that import transactions vary in the  number  of  parties
involved and the methods of import.  Some parties in  the import
process may be unaware of important information about the
chemical substance,  and,  in some cases, no one party  may know all
the information of concern to EPA.   Therefore,   EPA has attempted
to develop a definition that will ensure  that  the person who
knows the most about an imported substance will be required to
submit a notice.

-------
                               -37-
     EPA considered five alternative definitions of importer in
this rulemaking.  The major options are discussed below.

     1.  Options Considered

     Option 1 — Consignee

     This option designates one person, the consignee, as
responsible for notifying EPA of intent to import a new chemical
substance.  The consignee is the person to whom the goods are
delivered.  He may be any person, including a retailer or an
agent, involved in the import transaction.

     Option 2 — Consignee, Who Would Obtain Information
     from Other Persons

     Option 2 is the same approach as Option 1, but it also
requires the consignee to contact other persons for information
needed to complete the section 5 notice.  These other persons
include users and processors who can be identified and any
agents, customhouse brokers, or importers of record.  These
persons would provide the consignee with the information, or they
could send it directly to EPA.  They would, however, be under no
obligation to report the information to the consignee or EPA.

     Option 3 — Any Party Involved in the Import Transaction

     Option 3 is the definition of importer in the January 10,
1979, proposal.  This broad definition, adapted from the
definition of the U.S. Customs Service of the Treasury
Department, requires "any person who imports" to file the
notice.  Importers include the person primarily liable for the
payment of duties, the consignee, the importer of record, the
actual owner, and any transferee.  Under the January 10
definition, each of the persons listed is responsible for
ensuring that a notice is submitted to EPA.  The definition does
not identify one person responsible for submission of the notice.

     Option 4 — Principal Importer Responsible for Notice
     Submission

     Option 4 was published in the FEDERAL REGISTER of September
23, 1980 (45 FR 63606) as a clarification of the January 10
definition (Option 3).  This option uses the broad definition of
importer in Option 3, but it specifies that the "principal
importer" submit the section 5 notice.  The principal importer is
the first person who, knowing the new chemical will be imported,
selects the chemical substance and the total amount to be
imported.  This person is likely to be a processor, user, or
distributor of the chemical.

-------
                               -33-
     Option 5 -- Any Person Who Imports, or Knowingly Causes
     to be Imported, a Chemical Substance

     Under this option, the importer is defined as any person who
imports, or knowingly causes to be imported, a chemical
substance.  A person placing an order for a chemical substance in
a domestic transaction would not "knowingly cause" the import of
the substance unless he controlled the terras and conditions of
import.

     3.  Discussion

     As EPA stated in the Support Document accompanying the
January 10, 1979 proposal, the importer definition should
designate the person, or persons, who know the most about the
nature and use of the import.  Options 1 and 2 fail to do this.
Instead they identify the consignee as the person responsible for
submitting the notice.  The consignee is often a retailer or
agent, persons who ordinarily do not know information on the
imports that is useful or necessary for an initial screen.  If
they did not know this information, or it was not reasonably
ascertainable, they would not have to submit it.

     Option 2 addresses this problem by requiring the submitter
(the consignee) to ask for information from other parties,
including future users and processors.  Although the Option 2
submitter is often not the most knowledgeable party, he may
obtain information valuable for EPA's review from others.  Under
Option 1, submitters may also find it useful to seek information
from other more knowledgeable parties.  However, without the
requirement, they are less likely to do so.

     Under Option 3, SPA ensures that the most knowledgeable
person will be involved in the submission by making all parties
to the import transaction responsible for notification.  The
notice submitted under this option would include all required
information known to or reasonably ascertainable by any of the
parties to the transaction.  If this definition is properly
implemented by importers, it should provide a complete notice
with information sufficient for an initial screen by EPA.

     However, the Option 3 approach may not be easy to
implement.  When several parties are responsible for preparing a
submission, or contribute to its preparation, it may be
incomplete.  This may occur because of a disagreement among the
parties, or because certain parties do not cooperate and provide
necessary information.  (The same problem can occur in Option 2,
under which the consignee is obligated to contact other

-------
                               -39-
persons.   It  can  also  occur  in Options  1  and 5  if the consignee
or person  knowingly  causing  import  asks other persons for
information.)

     Commenters on the January 10 proposal  argued that,  by not
naming a principal party  responsible  for  submission,  the Option 3
approach might not serve  EPA's purposes.  EPA would have no
guarantee  that the most knowledgeable person would be actively
involved in the preparation  of the  notice,  or that the parties to
the transaction would  cooperate effectively.  In  response to
these comments, EPA  is considering  Option 4,  which would not
change the definition  in  Option 3,  but  would clarify  it  by
specifying that only the  "principal importer" be  responsible  for
submitting the notice.  Since  the principal importer  is  the party
who selects the imported  substance  and  is usually a processor,
user, or distributor of the  chemical, information necessary for
EPA's review  should  be known to or  reasonably ascertainable by
him.

     Option 5 does not identify a specific  party  in the  import
transaction as primarily  responsible  for  submitting the  notice.
The person who "imports or knowingly  causes"  a  substance to be
imported can be any  one of several  parties  (e.g.,  agents,
brokers).  These  persons  do  not necessarily know  much about the
chemical and  its  properties.   Therefore,  this alternative does
not achieve EPA's goal that  the most knowledgeable person submit
the notice.

     Commenters on the January 10,  1979,  proposal also raised  the
issue of the  responsibility  of the  notice submitter and  others
associated with the  preparation of  the  notice under the  joint-
submission options.  The  Preamble to the  January  proposal states
that, under the importer  definition (here Option  3),  each of the
persons listed is responsible  if he imports a substance  for which
EPA has not received a notice.   However,  it is  not clear whether
all parties to an import  transaction share  responsibility for  the
accuracy of the information  in a notice,  regardless of which one
submits it.  Option  2  also poses a  liability question with
respect to the adequacy and  accuracy of the information.   The
consignee  in this alternative  gathers information for submission
from future processors, users,  and  distributors and from persons
actually involved in the  import transaction.  The consignee would
be responsible for providing a complete submission; the  consignee
and others who contributed to  the preparation of  a notice would
share in the liability if the  information they  provided  was not
accurate.

     An advantage of joint notice submission, if  it works
properly, however, is  the sharing of costs  to prepare the notice
by the persons involved in the import transaction.  In Option  2
the consignee collects information  from other parties.   The cost

-------
                               -40-
of gathering and preparing this information, therefore, is shared
by these persons, thus reducing the consignee's financial
burden.  Under Option 3, where all the parties are involved in
the notice process, the responsibility for preparing the notice
is presumably shared by the various parties.  The disadvantages
of this arrangement is the possibility of duplication of
information and effort.  With responsibilities spread among
several persons, total costs may be greater than if one party is
responsible for preparing and submitting the notice.

     Under Options 1, 4, and 5, one importer party carries the
burden of financing the submission.  This is particularly
burdensome to importers in Options 1 and 5, since the consignee
and the person knowingly causing import are not necessarily the
persons who know the most, or can most reasonably ascertain,
information required by EPA for its review.  If they gather
information from other persons, their costs will be higher than
those incurred by the principal importer (Option 4).

     The risk of disclosure of trade secrets is possibly greater
in Options 2 and 3, the joint-submission options.  In Option 2, a
consignee is responsible for gathering information from other
persons.  Information may be disclosed when he transfers it to
EPA.  In Option 3 all the named parties share responsibility for
submitting a notice; therefore it is possible that confidential
business information may be revealed during preparation.

     Importers under Options 1, 2, 3, and 5 may wish to delay
their notices until they have obtained information from other
parties.  If they do, they will have to delay import.  But if
they submit their notices before securing certain information,
the review may be delayed.  For example, if they cannot
adequately identify the new chemical substance, EPA will find
that the submissions do not meet statutory requirements.  In this
case, the review process will not begin.  If they do not provide
other information necessary for review, EPA may use the proposed
section 8(a) supplemental reporting authority or, in some cases,
section 5(e) to require importers to provide the necessary
information.  However, these actions expend EPA resources, and
they involve delays that may have an adverse effect on the
importers.

     A disadvantage of the definitions in Options 1, 2, and 5  is
that they are inconsistent with the U.S. Customs Service
definition and with other definitions of importer under TSCA.
Options 3 and 4, however, are consistent with the Customs Service
definition, although broader, and with other TSCA definitions.

-------
                               -41-
     3.  Preferred Option

     EPA prefers the definition of  importer  in Option  3, which  it
proposed on January 10,  1979, and recently clarified in  a  notice
in the FEDERAL REGISTER.  This definition is consistent  with
other TSCA definitions and with the U.S. Customs  Service
definition.  Option 3 makes all parties to the import  transaction
responsible.  Under this option, EPA may be  more  likely  to
receive a submission that provides  enough information  for  its
review.  If each party is responsible, each  will  have  a  strong
incentive to see that any notice submitted is complete and
accurate.  The requirement should not be excessively burdensome,
since submitters will only be required to submit  information
known to or reasonably ascertainable by them.  On the  other hand,
because no single importer is designated as  the submitter, this
option may not serve EPA's purposes, as explained earlier.
Therefore, the Agency is also considering Option  4, which
clarifies the definition so that it requires the  "principal
importer" to submit the  notice.  In the notice of clarification,
EPA solicited comment on this option.

F.   Importer Contact of Foreign Manufacturers/Suppliers

     To prepare a section 5 notice  sufficient for an adequate
review, importers of new chemical substances may  need  assistance
from foreign manufacturers or suppliers.  This requires  a
cooperative arrangement  in which the foreign manufacturer
supplies the information that the importer lacks.  Since the
foreign chemical industry is not regulated by the U.S.
premanufacture program,  its role in this process  is voluntary.
Cooperation by foreign industry will depend  in part on the
benefits the manufacturer expects to derive  from  entering  the
U.S. market, the relationship of the importer to  the
manufacturer, the availability of the information to the
manufacturer, the resources needed  to provide the information,
and the manufacturer's concern over the risk of trade  secret
disclosure, which in part could result from  differences between
U.S. and foreign law protecting confidentiality.

     The cooperativeness of foreign manufacturers and  suppliers
may depend on the availability of requested  information  and the
extent of their concern  for confidentiality.  As  the Economic
Impact Analysis indicates, most foreign manufacturers  are  located
in the European Economic Community  and Japan.  Although  there are
certain differences in their notification programs, the  information
requirements for new chemical substances in  these countries
generally are or will soon be similar to those under TSCA.
However, foreign manufacturers may  be reluctant,  for reasons of
availability, cost, or confidentiality, to cooperate with  the
importer.

-------
                               -42-
     Foreign manufacturers can protect trade secrets from
disclosure during transit by submitting them directly to EPA.
Nevertheless, there may be conflicts between their interests in
secrecy and EPA's and the U.S. public's information needs.
Therefore, foreign manufacturers,  who are not legally obligated
to comply with EPA's requirements, may sometimes be reluctant to
submit information to EPA under section 5.  Obviously, the
absence of U.S. legal authority over foreign manufacturers is a
controlling factor in contacts between U.S. importers and foreign
manufacturers.  EPA will depend on cooperation of foreign
industry for this part of the premanufacture notification program
to function.

     Although the participation of foreign manufacturers and
suppliers is voluntary, EPA can require that importers contact
these persons and request that they submit information.  EPA
evaluated four approaches to the issue of importer contact of
foreign manufacturers and suppliers.

     1.  Options Considered

     Option 1 -- Mandatory Contact and January 10 Foreign
     Manufacturers/Suppliers Form

     In this option, importers would be required to ask foreign
manufacturers and suppliers to complete the Foreign
Manufacturers/Suppliers Form proposed on January 10, 1979.

     Option 2 — Mandatory Contact and Shortened Form

     Importers would be required to ask foreign manufacturers and
suppliers to complete a Foreign Manufacturers/Suppliers Form
consistent with changes in the domestic form proposed in the
October 16, 1979, reproposal.

     Option 3 — Mandatory Contact for Health and Environmental
     Effects Data

     Importers would be required to contact foreign manufacturers
and suppliers for health and environmental effects data and risk
assessments.

     Option 4 — No Mandatory Contact

     Importers would not be required to contact foreign
manufacturers or suppliers.

-------
                               -43-
     2.  Discussion

     The four approaches considered by EPA fall into two basic
categories:  mandatory contact and no mandatory contact.  The
mandatory contact alternatives, Options 1, 2, and 3, each require
the importer to contact the foreign manufacturer.  They differ in
the amount of information the importer requests.  The burden on
the foreign manufacturer to provide information decreases from
Option 1 to Option 3.  Under Options 1 and 2, the importer
provides the foreign manufacturer with a Foreign Manufacturers/
Suppliers Form, which he would complete and  submit to the
importer or directly to EPA.  This form is shorter than the form
that U.S. manufacturers and importers submit under section 5.  It
includes questions on manufacturer and supplier identity,
chemical identity, production and marketing data, physical-
chemical properties, and health and environmental effects data;
it does not include questions on occupational exposure, consumer
exposure, or environmental release.  Under Option 3, the foreign
manufacturer sends to EPA only health and environmental effects
data and risk assessments.

     Under Option 4, the importer is under no obligation to
contact foreign suppliers and manufacturers.  This approach works
well for importers who do not require additional information for
their notices.  It poses a problem, however, for importers who
need information for a complete submission.  If the importer does
not know the chemical identity, he will have to contact the
foreign supplier or manufacturer for that information, regardless
of a no-mandatory-contact provision.  If he  sends a section 5
notice to EPA without chemical identity, EPA would not consider
the notice complete and the review period would not begin.

     Under the mandatory contact options (Options 1, 2, and 3),
the importer will incur out-of-pocket expenses to contact foreign
suppliers and manufacturers.  Submitters under Option 4 may also
incur these out-of-pocket expenses if they believe that foreign
suppliers or manufacturers have information  necessary for their
notices, but they will not be required to do so.  Under all four
options, if submitters do not include enough information for an
adequate review, EPA may require more information under its
proposed supplemental reporting authority, or it may prohibit or
limit the import of the substance under section 5(e) pending the
submission of additional data.  These actions are most likely to
occur under Option 4, which does not require that the importer
contact foreign suppliers or manufacturers;  they are least likely
with Options 1 and 2.

     Foreign manufacturers and suppliers will incur costs if they
submit information under any of the options.  Of the mandatory-
contact options, Option 1 will be the most costly, Option 3 the
least.  The Foreign Manufacturers/Suppliers  Forms in Option 1 and

-------
                               -44-
2 will be less extensive than the domestic forms proposed on
January 10, 1979, and October 16, 1979, respectively; the costs
of filling them out will be correspondingly less.  Under all
these options, submissions by foreign manufacturers and suppliers
are voluntary.

     Foreign manufacturers and suppliers would incur a
nonmonetary cost because of the risk of trade secret
disclosure.  This risk would decrease from Option 1 to Option 4,
because the amount of information submitted to EPA would probably
decrease.  In each option, there may be a conflict between EPA's
and the U.S. public's need for information and the foreign
manufacturer's desire to protect confidential business
information.  Because EPA cannot compel foreign manufacturers or
suppliers to provide information under T3CA, the deciding factor
for this problem is the marketplace — whether or not the foreign
manufacturer or supplier will forego his U.S. market because of a
concern for confidentiality.

     Benefits to society will depend on how much information EPA
receives in the section 5 notice.  The more information available
to EPA, the more thorough the risk assessment, and the greater
the protection of human health and the environment.  Since Option
1 and 2 ask for more information than do the other options, they
are more likely to benefit society.  Under Option 3, EPA would
not receive much of the information requested in Options 1 and 2,
but it would receive health and environmental effects data and
risk assessments, which are likely to be the most useful
information.  EPA would be least likely to receive data under
Option 4.

     3 .  Preferred Option

     Foreign manufacturers and suppliers may have information
necessary for EPA's review.  Under Option 4, the importer is
under no obligation to contact these persons, and therefore EPA
may not learn of information that would affect its review.  For
this reason, EPA believes that a mandatory contact provision is
necessary and did not propose Option 4.

     The major difference in Options 1, 2, and 3 is the amount of
information requested from the foreign manufacturer.  Option 1
requires the most, Option 3 the least.  The forms for foreign
manufacturers and suppliers in Options 1 and 2 correspond to the
domestic forms proposed on January 10 and October 16.  Because
EPA now favors a limited form for domestic manufacturers, it
believes that the Foreign Manufacturers/Suppliers Form should not
exceed the October 16 requirements.  It prefers Option 2, which
would require the submitter to ask foreign manufacturers and

-------
                               -45-
suppliers to complete a limited form consistent with the October
16 reproposed form.  However, the Agency solicits comments on
whether Option 3, which requires submitters to ask foreign
manufacturers and suppliers only for health and safety data and
risk assessments, would meet its needs.

G.  Exporters

     Section 12(a) of TSCA provides that the Act applies to
chemical substances manufactured solely for export if EPA finds
that they will present an unreasonable risk to health or the
environment within the United States.  Therefore, if the
manufacture or processing of a new chemical substance presents
such a risk — for example, as a result of worker exposure or
release to the environment — EPA would be authorized to control
it, preferably before the risk occurred.  In the proposed
rulemaking, EPA has considered three alternative approaches to
premanufacture notification for new chemical substances
manufactured solely for export:  exporter notification under
section 5, exporter reporting under section 8(a), and no exporter
reporting.

     1.  Major Options

     Option 1 — Exporter Notification under Section 5(a)

     Under this option, proposed on January 10 and October 16,
EPA would require section 5 notices from manufacturers producing
new chemical substances solely for export.  Submitters would not
provide information on uses and exposures occurring outside the
United States.  They would complete the exporter form proposed on
October 16.

     Option 2 — Exporter Reporting under Section 8(a)

     This option would require exporters to submit a report under
section 8(a) containing the same information required in the
Option 1 exporter notice.  The notice would be filed 90 days
before first manufacture.  Companies with annual sales of less
than ?1 million would be exempt.

     Option 3 — No Exporter Notification

     Persons would not be required to report the manufacture of
new chemical substances solely for export.

     2.  Discussion

     Options 1 and 2 require that manufacturers of new chemical
substances intended solely for export notify EPA 90 days before
they begin manufacture.  In Option 1, the submission would be

-------
                               -46-
under section 5,  in Option 2 under section 3.  In both cases, EPA
would learn that a person intended to manufacture a new substance
for export before that manufacture took place.  The notices would
be similar in their information requirements; they would ask for
the information the October 16 reproposal required of
manufacturers producing a substance for the domestic market,
except that they would not request information on uses and
exposure occurring outside the United States.  Under both
options, EPA would have 90 days to assess the risk and determine
the hazard, if any, posed by the new substance before manufacture
began.  The similarity between Options 1 and 2 ends here.

     Under Option 1, if EPA finds that an export-only chemical
poses an unreasonable risk within the United States, it can act
to prohibit or limit its manufacture, processing, distribution in
commerce, or disposal under section 5(f).  If EPA requires
additional information for a reasoned evaluation, it can require
that information under its proposed section 8(a) letter
authority, or it can regulate the substance under section 5(e)
pending the development of the information.  Under Option 2, EPA
would not be able to act based on these authorities, and, if the
substance were produced by a small business, which is exempt from
report under section 8(a), EPA might not learn of its
manufacture.  If EPA did receive a section 8(a) notice, it would
have to rely on the rulemaking authorities of section 4, 5(a)(2),
6, or 7 to control the substance.  In most cases, these rules
would require months to promulgate; in the meantime manufacture
for export could begin unrestricted.  Of course, if a person
intended to manufacture the substance for a domestic use, he-
would have to submit a premanufacture notice.

     The costs of preparing and submitting notices under Options
1 and 2 are similar.  According to IGF estimates, costs of
submitting a section 5 export notice will range from $1,200 to
$6,900, somewhat less than the cost to complete a domestic notice
form (Economic Impact Analysis, p. 167).  EPA believes that costs
of preparing a notice under section 8(a) will fall within the
same range because the report will contain essentially the same
information.

     It is difficult to estimate the market size of chemicals
made solely for export,  but EPA believes that it is relatively
small.  According to the Economic Impact Analysis (p. 167),
solely-for-export chemicals probably do not represent a large
proportion of total business for most firms.  Therefore, EPA
believes that the impact of exporter notification would be
slight.  Exporters will generally have somewhat less of a
reporting burden than do other manufacturers subject to
premanufacture notification.

-------
                               -47-
     EPA costs to review submissions and to protect confidential
business information are also similar under Options 1 and 2.  A
difference in cost would occur, however, if EPA needed more
information, and the manufacturer did not submit it
voluntarily.  Under Option 1, EPA could make a letter request
under section 8(a) or, in some cases, issue a section 5(e) order;
under Option 2 EPA would have to issue a separate 8(a) reporting
rule or a section 4 testing rule.  These would require
considerably more Agency time and resources; they would involve
individual rulemakings instead of the expedited procedures
possible under Option 1.

     Option 2 will narrow the universe of export-only
manufacturers who will be subject to premanufacture notification
because section 8(a) >has a small business exclusion.
Manufacturers with annual sales under $1 million will not be
required to report.  This reduces the coverage under Option 2,
but it also lowers the overall costs for industry and EPA.

     Under Option 3, manufacturers do not incur the cost of
reporting export-only new chemical substance to EPA.  EPA,
likewise, will not have to review notices on these exports.  From
EPA's and society's viewpoint, however, Option 3 is the most
costly.  EPA will have no way to learn of plans to manufacture a
new chemical substance solely for export and will not have an
opportunity to evaluate the substance for any risks associated
with its manufacture in the United States.  If such manufacture
does involve a hazard — for example, to workers during
manufacture or to the environment as a result of waste disposal
-- EPA will learn of it only when damage occurs.  The Agency,
therefore, may have difficulty in acting quickly to stop or
prevent damage to health and the environment.  Society will incur
costs associated with the hazard, and will suffer damage that
might have been prevented if EPA had been notified before
manufacture began.

     3.  Preferred Option

     EPA prefers Option 1, which combines the exporter
notification requirements proposed on January 10 and the exporter
form proposed on October 16.  The Agency believes that it is
essential to take every possible step available under section 5
to prevent hazards associated with new chemical substances.
Commenters on the January 10 and October 16 proposal argued that
section 12(a)  of TSCA prohibits EPA from requiring section 5
notices for new chemical substances manufactured solely for
export.  Section 12(a)(1) states that, except for section 8, TSCA
does not apply to a substance that is manufactured solely for
export.  This general principle, however, is qualified by section

-------
                               -48-
12(a)(2),  which provides that the Act applies to such a substance
if EPA finds that it will present an unreasonable risk to health
or the environment within the United States.  If EPA is not aware
that a new substance is being manufacturing domestically, the
Agency could not act to regulate the substance until a
significant health or environmental problem occurred.  This is
contrary to the preventive approach to toxic substances embodied
in section 5.  Therefore, when read in light of the entire
framework of TSCA, section 12 authorizes EPA to require
premanufacture notices for new chemical substances manufactured
solely for export.

     The notice requirements for Options 1 and 2 are very
similar.  However, the Option 2 approach does not allow EPA the
same opportunity to act on exported substances before manufacture
begins.  Option 2 exporters can begin to manufacture substances
that EPA determines to be hazardous while EPA assembles the
necessary data to undertake a regulatory action.  Under Option 1,
EPA will be able to act effectively in cases of unreasonable risk
before any harm has occurred.

H.   Supplemental Reporting

     For certain chemicals of concern, EPA may need additional
information from notice submitters or other persons during the
review period.  This is likely if EPA adopts the limited
reporting requirements of the October 16 reproposal. In many
cases, submitters will provide the information voluntarily.  In
others, however, they may not cooperate.  In these cases, EPA
needs a way to obtain the information quickly, before it is too
late to act under section 5(e) or 5(f).  EPA may also need the
authority to gather information from other persons, including
processors or persons with health and safety studies.

     EPA has considered three approaches to a supplemental
reporting authority to provide information for the premanufacture
review.  Options  1 and 2 require mandatory reporting; Option 3
does not.

     1.  Options Considered

     Option 1 --January 10 Proposal

     Under this option, proposed on January 10, EPA could require
certain persons to report additional information on the
manufacture, processing, distribution in commerce, use, or
disposal of a new chemical substance if that information was
necessary for an  evaluation of the substance, and  if it was known
to or reasonably ascertainable by those persons.   The notice
submitter, potential processors of the new chemical substance,
and manufacturers or importers of reactants of unknown identity

-------
                               -49-
or composition used in the manufacture of the new chemical
substance could be subject to the requirement.  The Assistant
Administrator for Pesticides and Toxic Substances or the Deputy
Assistant Administrator for Chemical Control would issue the
information requests by letter under the authority of section
8(a) during or after the review period.  In addition, EPA could
require any person to submit relevant health and safety studies
of new chemical substances during or after the review period
through a supplemental reporting requirement under section 8(d).

     Section 8(a) includes a small business exclusion, which, for
the purposes of supplemental reporting, was defined in the
January 10 proposal as exempting companies with annual sales of
less than $1 million.  Therefore, processors of the substance and
manufacturers or importers of unknown reactants with less than
this sales volume could not be required to report.  However,
original notice submitters, even if they were small businesses,
would be required to provide information that supplemented,
provided further detail on, or clarified information in the
original notice.  EPA believes that small businesses can be
required under the authority of section 5 to submit information
that could have been required in the original notice.  All
persons, including small businesses, could be required to submit
health and safety studies in their possession under a section
8(d) supplemental reporting requirement, because this section has
no small business exclusion.

     The criteria for using supplemental reporting in this option
are broad.  There is no provision to appeal the individual
letters requiring information.

     Option 2 — October 16, 1979, Reproposal

     Option 2 (the October 16 reproposal), like Option 1,
provides a letter-writing authority under sections 8(a) and 8(d)
to get additional information necessary for Agency review of a
new chemical substance.  It applies to the same persons, but
differs from Option 1 in several respects.  Under Option 2,
criteria governing EPA's use of supplemental reporting are more
detailed.  Option 2 also specifies the types of information EPA
may require if these criteria are met.  In addition, if original
notice submitters are small businesses, they need only supply
information that explains or clarifies the premanufacture notice,
not information that supplements it.  The reporting requirement
applies only during the review period; it does not extend beyond
the close of the period, as it does in Option 1.  Option 2 also
provides a mechanism that allows submitters to appeal individual
requirements to supply information.

-------
                               -50-
     Option 3 — No Mandatory Supplemental Reporting

     Option 3 does not provide for mandatory supplemental
reporting.  EPA would have to rely on voluntary compliance when
it requested more information from submitters and other
persons.  If they did not respond, EPA would have to issue a se-
parate section 8 rule to get the information.  Or, if a substance
met the appropriate criteria, EPA could issue a section 5(e)
order prohibiting or limiting the manufacture, processing,
distribution in commerce, use, or disposal of the substance
pending the submission of the necessary information.

     2.  Discussion

     The adoption of a limited notice form (see Section II(A),
Reporting Requirements) provides a persuasive argument for
Options 1 and 2.  A comprehensive form, such as the one proposed
on January 10, 1979, generally gives information sufficient for a
detailed evaluation of a new chemical substance, if that
information is known to or reasonably ascertainable by the
submitter.  Because only some new chemicals will undergo detailed
review, this comprehensive form may impose an unnecessary burden
on many notice submitters.  The limited form of the October
reproposal reduces the initial burden of notice submission.  With
the limited form, however, EPA needs a way to obtain more
information on chemicals of concern.  Supplemental reporting
provides this.  When EPA requires more information to determine
if a new chemical substance is a potential candidate for
regulatory action, it can request this information under its
proposed supplemental reporting authority-

     Option 3, which has no mandatory supplemental reporting
requirement, will provide difficulties for EPA's review if a
limited form is adopted.  EPA can request the information, but it
does not have the authority to enforce its request, as it does
under Options 1 and 2.  Under this option, the Agency must rely
on industry cooperation.

     Many commenters on the January 10 proposal (Option 1)
questioned EPA's authority to require information by letter.
They argued that rulemaking on a case-by-case basis was more
consistent with the Act.  The case-by-case approach is proposed
as Option 3.  Under this option, EPA would promulgate a separate
section 8(a) or 8(d) reporting rule each time the Agency needed
more information.  The problem with this approach is that the 4
to 6 months required for each rulemaking would conflict with the
90-day (or at most 180-day) review period for new chemical

-------
                               -Si-
substances.  The time needed to promulgate an individual rule for
a specific chemical, together with the time before EPA received
data under the rule, would exceed the statutory review
schedule.  This approach would limit the usefulness of the
information received, and it would generally foreclose regulatory
action based on that information under section 5(e) or 5(f) —
actions that must be taken within 135 days of receipt of a
section 5 notice.

     For this reason, EPA believes that a section 8 letter-
writing authority provides a better approach.  In January and
October in a rulemaking subject to notice and comment, EPA
proposed and reproposed procedures for using the authority, the
criteria for when it would be used, the kinds of information that
could be required under it, and the procedures for appeal of
individual requests  for information.  With this general framework
in place, EPA could  secure necessary information during the
review period in an  expedited fashion.  The ready availability of
information, or the  possibility of determining that it is
lacking, is particularly important for actions under sections
5(e) and 5(f).

     Under Options  1 and 2, EPA would informally request
information from the submitter or other persons before it sent a
section 8 reporting  letter.  If the information was provided, EPA
would avoid further  administrative costs, and the recipient of
the request would incur only the costs of preparing and sending
the information.  Costs for submitters who failed to respond to
the informal request but did respond to the section 8 (a) letter
would be no higher,  unless EPA as a result of the delay extended
the review period under section 5(c).  Failure to respond to the
section 8(a) letter  might lead to an enforcement action or
regulation of the new chemical substance under section 5(e) or
5(f).  In this situation, the cost to EPA and the submitter, of
course, would be higher.

     It is difficult to estimate the out-of-pocket costs of
responding to a section 8 supplemental reporting requirement.
The cost will be determined by the frequency with which EPA uses
that authority.  This in turn will be affected by the level of
detail in the original submissions.  The costs of the specific
responses will vary  with the chemical, the person subject to the
reporting requirement, and the information requested.

     Costs will be different in Options 1 and 2.  Option 1 is
broader, both with  respect to the situations it covers and the
information that can be requested.  Therefore, out-of-pocket
costs should be higher for Option 1.  The appeal procedure of
Option 2, however, will entail an additional cost.  An appeal
will involve administrative costs for EPA (diverting resources
from the review of other substances) and for the appealing

-------
                               -52-
party.  Nevertheless, commenters on the January  10 proposal
argued that an appeal procedure was necessary to provide  the
submitter protection from arbitrary action by EPA.

     Costs to industry other than out-of-pocket  costs  are more
difficult to measure.  The introduction of new substances into
the market may be delayed if EPA extends the review period under
section 5(c) to allow for supplemental reporting.  However, the
effect of this should not be great, because the  substances
subject to supplemental reporting will be slated for detailed
review.  In this case, the notice period would have been  extended
even without the supplemental reporting requirement.

     The effect of Option 3 on industry is also  difficult to
assess.  On the one hand, submitters will not be subject  to
reporting under the section 8 letter-writing authority.   However,
if they do not provide sufficient information in their notices,
and they do not later provide the information voluntarily, EPA
may be required to take more actions under sections 8  and 5(e).
This situation could be particularly detrimental to the submitter
if the information requested by EPA would have decreased  the
Agency's concerns and eliminated the need for regulatory  action.

     To protect human health and the environment from  risks
associated with new chemical substances, EPA must be able to
secure information on these substances and to act under section 5
before they have entered commercial production.  Under Option 3,
which has no mandatory supplemental reporting authority,  EPA
would often find it difficult to act on new substances during the
review period.  In many cases,  it would lack the necessary
information to support an action under sections  5(e) or 5(f).
Individual,  case-specific rulemakings under section 8  to  secure
the necessary information would rarely provide that information
before the review period — and the possibility of acting under
section 5(e) or 5(f) — had ended.  Options 1 and 2, however,
ensure that EPA has the authority to get necessary information
during the review period.

     3.  Preferred Option

     EPA did not propose Option 3, because a no-mandatory-
reporting scheme would limit its ability to fulfill the mandate
of section 5.   EPA has no assurance that information will always
be given voluntarily.  When it is not, the Agency will find it
extremely difficult to assess the risks of a new chemical
substance and to act on potentially hazardous new chemicals
before they cause harm to human health or the environment.
Furthermore, a supplemental reporting authority will eliminate
the need for a more extensive and burdensome section 5 notice

-------
                               -53-
form.  Without section 8 letter-writing authority, EPA will lack
a way to obtain more information on an expedited basis, and a
major justification for the streamlined form will be removed.

     Of the two options discussed, EPA prefers Option 2.
Although Options 1 and 2 are very similar, EPA believes that
Option 2 addresses some of the chief concerns expressed in the
comments on the January 10 proposal, while still meeting the
information needs of the Agency and the public.  The January and
October proposals have provided adequate opportunity for notice
and comment by persons potentially subject to supplemental
reporting under Option 2.  This option also includes an appeal
procedure, which provides individual redress for persons subject
to supplemental reporting.  Option 2 further restricts the scope
of supplemental reporting by limiting it to the notice review
period, by setting forth in more detail the criteria governing
EPA's use of supplemental reporting, and by specifying the types
of information EPA can request.  These changes clarify the scope
of SPA's authority for industry, and they establish specific
guidelines for the Agency.

I.   Processor Notification

     Manufacturers of several classes of chemicals are
specifically exempt from the Inventory and from section 5
requirements:  byproducts; tobacco and tobacco products; nuclear
materials; substances used solely as pesticides, firearms,
ammunition, foods, food additives, drugs, and cosmetics; and
substances manufactured before January 1, 1975, and not processed
or reported for the Inventory.  In addition, persons
manufacturing new chemical substances under test marketing
exemptions, and persons manufacturing new substances in small
quantities solely for research and development  (R&D), are exempt
from notice requirements if they comply with EPA restrictions for
these activities.  The substances described above are referred to
as "exempt substances" in this section.

     A processor notification requirement for all exempt
substances would close a gap in the section 5 regulatory scheme
by requiring persons to submit notices to EPA if they intended to
process any exempt substance for nonexempt purposes.  Without
such a requirement, a new substance manufactured or imported for
an exempt purpose (such as a pesticide) could be processed in any
quantity for a TSCA use without a report being  submitted to EPA
and without prior EPA review for possible effects on health or
the environment.

-------
                               -54-
     EPA has considered several alternative approaches to
resolving this issue. The approaches differ by who must report,
what activities trigger reporting, what information must be
reported, and what TSCA authorities they depend on.  This section
considers four major options; other options are discussed in the
Economic Impact Analysis (Part II, Chapter 8) and the August 15,
1980, proposed processor notification rule (45 FR 54645).

     1.   Options Considered

     Option 1 -- January 10 Proposal

     This option, proposed on January 10, 1979, would require
manufacturers or importers to report the processing, use, or
distribution of certain exempt substances.  Specifically, a
manufacturer or importer would have to submit a section 5 notice
90 days before he processed, used, or distributed an R&D or test-
marketed chemical in a manner inconsistent with the terms of the
exemption.  Persons who did not manufacture or import an exempt
substance, but who intended to process the substance for a TSCA
commercial purpose, would not be permitted to submit a notice.
Substances reported under this option would be added to the
Inventory when commercial activity began.  Mandatory notification
costs under the January 10 proposal are estimated to range from
$3,740 to $22,160 (ADL, Impact of TSCA Proposed Premanufacturing
Notification Requirements,  p. V-17).

     Option 2 — August 1980 Proposed Processor Reporting

     Under this option, proposed by EPA on August 15, 1980 (45 FR
54642),  persons would be required to submit section 5 notices at
least 90 days before they processed a previously exempt
substance, as defined above, for a TSCA commercial purpose.
Processor notification would be required whether or not the
person was also the original manufacturer or importer.  The
notice would include all the information required by the notice
form proposed on October 16, 1979, as well as the name of the
supplier or future suppliers of the substance.  The cost of
providing mandatory information under this alternative would
range from $1,155 to $8,925 (ICF, Economic Impact Analysis,
p. 186).

     EPA would require notices under the authority of sections
5(a)(l)  and 5(a)(2).  After the review period, if EPA did not
take action on the substance, the submitter could process it for
TSCA commercial purposes,  and it would be added to the TSCA
Inventory-

-------
                               -55-
     Option 3 — Section 8. Processor Notification

     All persons who process previously  exempt  substances  for
TSGA commercial purposes would be  required  to report  to EPA under
section 8(a) at commencement of processing.  Section  8(a)
notices would provide company name, contact person, chemical
identity, amount of the substance  to be  processed, an estimate of
consumer and worker exposure, a description of  categories  of use,
available health and safety data,  and the name  of the supplier.
The cost of providing this information would range from $724 to
$4,450 (ICF, Economic Impact Analysis, p. 186).

     "Small processors" are exempt from  section 8(a)  reporting
and would not submit notices under this  alternative.  Substances
reported to EPA would not be added to the TSCA  Inventory when
processing began.

     Option 4 — August Proposal with Exemption for One-time
     Processing

     Option 4 would require processor reporting for exempt
substances under section 5, as outlined  in  Option 2.  However,
the reporting requirement would be coupled  with an exemption
scheme permitting the limited processing of selected  chemicals.

     The exemption scheme would apply to R&D and test-marketed
substances processed on a one-time basis for TSCA commercial
purposes solely as an alternative  to disposal.  Persons who
intended to process R&D and test-marketed substances  once  as an
alternative to disposal in quantities under 500 pounds would not
be required to report.  Persons who intended to process such
substances once as an alternative  to disposal in quantities over
500 pounds would be subject to limited reporting requirements
under section 8.  These requirements would  be the same as  the
requirements outlined for Option 3.  Substances reported under
section 8 would not be added to the Inventory when processing
began,  and small businesses would  be exempt from this reporting.

     2.  Discussion

     In considering the problem of processing previously exempt
substances for TSCA commercial purposes, EPA addressed several
issues.  These include:  (1) Whether to  require notification for
such processing, (2) What the applicability of  the reporting
requirement should be, (3) If reporting was required, what data
would have to be submitted, (4) How EPA could regulate chemicals
of concern under TSCA authorities  after the notices were
received, (5) Whether to add reported substances to the TSCA
Inventory,  and (6) What costs would be imposed  on industry and
EPA.  Resolution of each of these  issues played a part in  shaping
the approach EPA proposed.  These  are discussed in turn.

-------
                               -56-
         a.  Notification for commercial processing of exempt
substances.  If previously exempt chemicals are processed for
commercial purposes,  but the processors are not permitted to
submit a notice, EPA will be unable to assess the risks
associated with that processing, or with distribution in
commerce, use, or disposal of the substance for TSCA commercial
purposes, before those activities occur.  Yet these activities
might pose significant risk to health or the environment.
Therefore, EPA  proposes to require reporting for commercial
processing of exempt substances.  This reporting is consistent
with section 5 of TSCA, which requires the Agency to review new
chemical substances and significant new uses before manufacture
or import for commercial purposes.  Many substances are exempt
from Inventory and section 5 reporting when they are manufactured
or imported, yet persons other than the manufacturer or importer
might process them for TSCA commercial purposes.  By requiring
reporting before these substances are processed for TSCA
purposes, EPA will be able to review any risks they will pose, in
the same way that the Agency considers risks associated with new
chemicals to be manufactured or imported for TSCA purposes.

         b.  Authority for and scope of processor notification.
Under the January 10 proposal (Option 1), EPA requires section 5
notification by manufacturers and importers of R&D and test-
marketed substances before they process, distribute, or use those
substances in a way inconsistent with the terms of the
exemption.  Other persons could process exempt substances for
TSCA commercial purposes without notification.  EPA, however,
believes that requiring reporting for only some classes of exempt
substances is not desirable because any exempt substance could be
processed for a TSCA purpose and placed in commerce.  Singling
out only R&D or test-marketed substances for reporting does not
fulfill EPA's goal of reviewing substances never reported under
TSCA before they are processed for TSCA commercial purposes.
Because the January 10 proposal (Option 1) would only require
reporting for R&D and test-marketed substances, and then only if
the processor of the substance was the manufacturer or importer,
EPA decided that this approach does not sufficiently cover all
substances of concern.  The Agency prefers an option that
requires notification for all categories of substances.

     EPA could issue such a rule under section 8(a) (Option 3) or
sections 5(a)(l) and 5(a)(2) (Option 2).  Under Option 3, EPA
would require all processors of previously exempt substances  for
TSCA commercial purposes to submit limited section 8(a) notices
at the commencement of processing.  Small processors would be
exempt from reporting because section 8(a) contains a small
business exemption.  Under Option 2, proposed on August 15, 1980,
EPA would require that processors, including small processors,
submit a section 5 significant new use notice at least 90 days
before processing began.  EPA has assessed the factors listed in

-------
                               —5 7 —
section 5(a)(2),  and, based on  this  assessment,  the  Agency
proposed  in August that  the transition  of  chemicals  from exempt
manufacture or  import to nonexempt commercial  processing
constituted a  "significant new  use"  under  TSCA.   Therefore,  under
Option 2, persons intending to  process  a previously  exempt
substance for TSCA commercial purposes  would be  required to
submit a  notice under section 5(a)(l)(B).

     Options 2  and 3 make all categories of exempt substances
subject to reporting, if they were processed for TSCA  commercial
purposes.  EPA, however,  is considering an exemption for one
category  of processing.   Option 4 would permit processing with no
notification for  R&D or  test-marketed substances processed in
lieu of disposal  for nonexempt  purposes in quantities  of less
than 500 pounds.  Persons processing substances  under  the same
circumstances in  quantities of  greater  than 500  pounds would
submit section  8  notices, but the substance would not  be added to
the Inventory.  This distinction by production volume  exempts
processing likely to present less of a  risk, because less of the
substance would be processed.   This  scheme would mean  that a
person would not  have to dispose of a chemical that  had  only a
limited one-time  commercial application if section 5 notification
costs were higher than the expected  financial  return for the
commercial application.

     EPA believes that substances manufactured solely  in small
quantities for  R&D or for test  marketing may belong  in a separate
category  from other exempt substances.  For example, a substance
manufactured as a pesticide, food, or drug may fail  in a
nonexempt commercial use, but will still have  its primary use as
a pesticide, food, or drug as an alternative.  However,  a
substance manufactured or imported for  R&D or  for test marketing
may only have a nonexempt commercial use as an alternative to
disposal.  In this case,  processing on  a one-time or limited
basis to  "use up" the substance is much more likely  to occur.

     Several arguments can be made for  allowing  this processing
without EPA notification.  First, use of the substance may cause
less harm to the  environment than disposal.  Second, if
notification costs are greater  than the benefits of  one-time
processing,  the processor may incur an  increase  in overall
costs.  Third, it may not be desirable  to  add  a  substance to the
Inventory if it will immediately lose its  commercial status.  If
other TSCA uses are later discovered, it may be  more appropriate
for EPA to review the substance at that time,  when more
information is available.  However, there  is a strong  argument
for mandatory EPA notification.  The "using up"  of the substance
may involve significant  exposure to humans and the environment.

-------
                               -58-
     EPA does not now have sufficient information on the
situations in which persons process R&D and test-marketed
chemicals for commercial purposes on a one-time basis as an
alternative to disposal.  Therefore, it has not proposed this
exemption, but invites further comment.

         c.  Information requirements.  Under Option 1, EPA would
require that submitters complete the notice form proposed on
January 10, 1979 — although notification would be required only
for manufacturers or importers processing an R&D or test-marketed
substance in ways inconsistent with the terms of the exemption.
In the August 1980 proposal, EPA reduced the information
requirements to those of the October 1979 form.  Section II(A),
Reporting Requirements, of this Regulatory Analysis explains this
in detail.  In the August proposal, however, EPA also added a few
data requirements for processors.  These data were the names of
suppliers and future suppliers; descriptions of the manufacturing
processes, if known; and, for R&D substances, any information on
health or environmental risks that the submitter received under
section 720.14(a)(2) or evaluated under section 720.14(c) of the
January proposal.  These additional requirements are not
burdensome and will assist the Agency in assessing the risks
associated with the commercial processing of exempt substances.

     Under Option 3, which requires a limited section 8(a)
notice, EPA would reduce the reporting burden for submitters
still further.  EPA, however, does not believe that such a
limited notice would provide enough information for an initial
assessment of the risks posed by a chemical.

         d.  Control of reported chemicals.  If EPA decides to
regulate exempt substances reported under any of the various
options, it is important that these requirements be imposed
expeditiously to protect the public and the environment before
any possible harm occurs.  The options would require EPA to use
different authorities to control chemicals of concern, depending
on whether the chemical was initially reported under section 5 or
section 8.  As discussed more fully in Section II(G) of this
Regulatory Analysis, regulation under section 5 would be less
burdensome to EPA, and it would allow more timely action.

     Under the section 5 notice options, EPA would use sections
5(e) and 5(f) to regulate chemicals that may or will present
unreasonable risks.  These  sections allow EPA to act by order,
with court action as necessary.  Substances reported under
section 8 would not be subject to  regulation under section 5(e)
or 5(f).  Instead, the Agency would be forced to act on chemicals
under section 4, 5(a)(2), 6, or 7, which would entail greater
burden and, in most cases, would require considerable time to
promulgate.

-------
                               -59-
         e.   Addition of reported substances to the TSCA
Inventory.  Under Options 3 and 4, EPA would not add previously
exempt substances to the TSCA Inventory when it received a
section 8 notice.  Section 8 notices, as described earlier, might
not contain information necessary for an initial screen, even
though it was known or reasonably ascertainable.  Therefore,
these notices may not provide enough information for the
evaluations that EPA wishes to conduct on exempt substances
before they are processed for nonexempt commercial purposes.  For
this reason, these substances should not be placed on the
Inventory.  If the substances were placed on the Inventory,
persons who intended to manufacture or import them for TSCA
commercial purposes would not notify EPA; as a result, the
substances might enter commercial production without review under
section 5.  Under Option 2, the substances would be subject to
section 5 notice before they were manufactured or imported for
TSCA commercial purposes, and would go into production for these
purposes only after EPA had evaluated a full section 5 notice.

         f.   Reporting costs for industry.  The initial costs of
submitting mandatory information under the Options 1, 2, and 3
are given in Table II-4.
                            TABLE II-4

      ESTIMATED COSTS OF COMPLETING MANDATORY PROCESSOR  FORM




      Option                                      Cost



Section 8(a) reporting  (Option 2)               725- 4,450

August 15, 1980 (Option 3)                    1,155- 8,925

January 10, 1979 (Option 1)                   3,740-22,160
     Section 8 notices would be significantly less expensive for
submitters than section 5 notices.  Section 8 notices would also
impose lower postsubmission costs.  Because notices would be
submitted at commencement of processing, there would be no
delay.  However, section 5 notices would have to be submitted
later if a person intended to manufacture or import the

-------
                               -60-
substance for TSCA commercial purposes.  If both section 8 and
section 5 notices were submitted, the cost and burden to industry
would be higher than the costs of submitting either notice alone.

     Under Option 2 (August reproposal), EPA would obtain enough
information to conduct an initial assessment; if necessary, it
could then require more data on chemicals of concern through
supplemental reporting.  Therefore, the August proposal reduces
the cost of section 5 notification without substantially reducing
the effectiveness of EPA's review.

     The January 10 approach (Option 1) and section 8(a)
processor notice (Option 3) would involve a cost to industry not
reflected in the costs of notification.  Under the January 10
approach, only processors of R&D and test-marketed substances
would be permitted to submit section 5 notices; other exempt
substances processed for TSCA commercial purposes would not be
reported and would not go on the Inventory.  Under Option 3,
processors would submit section 8 notices, but the previously
exempt substances would not be added to the Inventory.  In both
Options 1 and 3, therefore, persons would have to submit^ a
section 5 notice before they could manufacture or import
previously exempt substances that had been processed for TSCA
commercial purposes.  If the processor was not the manufacturer
or importer, and the manufacturer learned of the commercial
processing, the manufacturer would be required to halt
distribution for the commercial purpose and submit a notice.

     Under Option 2, however, the reported substances would go on
the Inventory.  Processors and any other persons could then
manufacture or import the substance for nonexempt purposes
without the potential delay of notification.  They would also be
able to avoid interruptions in supply that would occur in Options
1 and 3 if the manufacturer learned of the processing but did not
submit a notice.

     3.  Preferred Option

     EPA prefers Option 2, which it proposed in August 1980.
Processor reporting as proposed offers the most effective
environmental protection because it allows EPA to review exempt
chemicals before they are processed for TSCA purposes.  To assess
the risks that might be posed by these chemicals, the Agency must
require enough information to conduct an initial screen. Option 2
achieves this by requiring that processors supply the information
requested on the October 16 form, if it is known to or reasonably
ascertainable by the submitter.  Also, because processors would
submit section 5 notices under Option 2, EPA will be able to

-------
                               -61-
regulate previously exempt substances processed for TSCA
commercial purposes under sections 5(e) and 5(f).  The substances
would be added to the TSCA Inventory when they are processed for
commercial purposes.  Finally, under this option, small as well
as large processors would report.

J.  Possession or Control

     Under section 5(d)(l)(.Q), a notice submitter is required to
provide any test data in his  "possession or control."  In the
January 10, 1979, proposal, EPA defined information in a
submitter's possession or control as information:  (1) In the
submitter's own  files, (2) In commercially available data bases
to which he has  purchased access, or (3) In files maintained in
the course of employment by employees or other agents of the
submitter who are associated with research, development, test
marketing, or commercial marketing of the substances.  This
definition is common to the four options discussed in this
section.  The options, however, differ in their treatment of test
data in the possession or control of companies affiliated with
the submitter, and in the participation of these affiliated
companies in the commercial development of the new chemical
substance.

     1.  Options Considered

     Option 1 — In Possession of Subsidiaries, Parent
     Company, and Parent's Subsidiaries Associated in the
     Present Venture

     The first option was proposed on January 10, 1979.  Under
this option, ''possession or control" means in the possession or
control of the submitter, any of his subsidiaries, his parent
company, or any  company that  the parent company owns or controls
if the subsidiary, parent company, or subsidiary of the parent
company is associated with the submitter in the research,
development, test marketing,  or commercial marketing of the
substance.  Under this option, one company "owns or controls"
another company  if it owns or otherwise controls at least 50
percent of the other company's voting stock.

     Option 2 —In Possession of Subsidiaries Associated
     in the Present Venture

     The second  option includes data in the possession  or control
of the submitter or any of his subsidiaries if they are
associated with  the submitter in the research, development,  or
marketing of the new chemical substance.  Unlike Option 1,
however,  it does not include  data possessed or controlled by a

-------
                               -62-
parent company or by companies owned by a parent company, even  if
the parent company or its subsidiaries are associated with the
submitter in the research, development, or marketing of  the
substance.

     Option 3 — In Possession of Subsidiaries, Parent
     Company, and Parent's Subsidiaries, Including Those
     Not Associated in the Present Venture

     Like the first option, Option 3 defines possession or
control to mean in the possession or control of the submitter,
any of his subsidiaries, his parent company, or any companies
owned or controlled by the parent company.  Again, owning or
controlling is defined as owning or controlling at least 50
percent of a company's voting stock.  However, Option 3 does not
limit the definition 'to companies associated with the submitter
in any particular venture.

     Option 4 — Modified Option 1

     The fourth option has been considered by EPA, but is not
analyzed in the Economic Impact Analysis.  Like Option 1, this
definition includes data possessed or controlled by the
submitter, any of his subsidiaries, his parent company, or any
company that the submitter or his parent company owns or
controls, if the subsidiary, parent company, or subsidiary of the
parent company is associated with the submitter in the research,
development, test marketing, or commercial marketing of the
substance.  Under this option, unlike Option 1, one company  "owns
or controls" another company if the parent company exercises
"control in fact" over the other company, irrespective of its
percentage of stock ownership in that company.  Control in fact
would mean the direct or indirect possession of the power to
direct the management and policies of a company, whether through
ownership of voting securities, by contract, or otherwise.

     2.  Discussion

     Under each option,  submitters possess or control data in
commercially available data bases to which they have purchased
access.  The cost of retrieving data from such a data base is
reasonable,  and the data may be valuable to EPA.  Also under each
option, submitters possess or control information in the files of
their employees and agents.  This is necessary to secure relevant
data and should not be unduly burdensome to submitters.

     Options 1, 3,  and 4 require the submission of data possessed
by subsidiaries,  parent companies, and subsidiaries of parent
companies in addition to data possessed by the submitter.  This
requirement is designed to obtain sufficient data without being
unduly burdensome.   Without this comprehensive approach, many
data might be missed since chemical research and testing may be

-------
                               -63-
performed by parent corporations and their subsidiaries.  In
addition, if the definition did not include parent's
subsidiaries, companies could reduce reporting requirements by
effecting a corporate change from divisions to Wholly owned
subsidiaries.  Because research may be performed by the foreign
affiliates of submitters, the definitions would also apply to
those companies.

     Option 2 is limited to the submitter and its subsidiaries.
This definition is less burdensome than Option 1.  However, it
would not reach relevant data gained through research or testing
by parent companies and their subsidiaries if that data were not
contained in the files of the submitter.

     In Options 1, 2, and 3, one company is considered to own or
control another if the parent company owns or controls the
majority of voting stock of the other company.  In Option 4, one
company is considered to own or control another if the parent
company exercises control in fact over the other company
irrespective of its percentage of stock ownership in that
company.  This definition would reach data not reached by the
other options.  It follows the approach of other statutes and
regulations, such as the Securities and Exchange Act and the
regulations implementing the Export Administration Act.  The
definition could be interpreted on a case-by-case basis, using
rebuttable presumptions of control based on objective criteria.
However, because it is not a purely objective standard, this
option would be harder to administer than the other options.

     Options 1, 2, and 4 limit their reach to companies
associated with the submitter in some aspect of a particular
venture.  Option 3 is not limited to companies associated with
the submitter in any particular venture.  Theoretically this
definition would yield the most data.  However, the files of
companies not working on a venture involving the substance in
question may contain data of marginal relevance.  Further, the
definition may create burdensome search requirements since, in
some cases, it would reach hundreds of companies.

     3.  Preferred Option

     EPA prefers the definition in Option 1, which was proposed
on January 10, 1979.  While the definition extends the reporting
requirement beyond the submitter, it is not unduly burdensome.
If the companies involved in the venture use an integrated search
system, the direct economic impact of the reporting requirements
will be minimal.

     The preferred definition may not reach data in the
possession of companies controlled in fact by the submitter, or
data in the possession of companies legally controlled by the

-------
                               -64-
subraitter but not involved in the development of the chemical
substance.  These limitations, however, are not of major
concern.  In practice, companies involved in the development of a
chemical substance will assemble the most complete and current
data base.  In addition, submitters would generally know of data
possessed or controlled by a company not involved in the
development of the particular chemical substance.  Therefore,
they would have to describe these data in their notices.  EPA
could obtain the data through a supplemental reporting
requirement under section 8(d) or by a subpoena under section
11(c).  To expand the definition beyond that of Option 1 might be
unduly burdensome to affected companies.  Similarly, any
expansion of the concept of corporate control beyond the majority
of voting stock ownership standard would be confusing to affected
companies and administratively burdensome to EPA.

               III.  COMPREHENSIVE PROGRAM OPTIONS
    The previous chapter discussed various options for resolving
each of the ten major issues in the rulemaking.  EPA has
constructed three basic approaches, or Comprehensive Program
Options (CPO's), for section 5 rules by selecting one option from
each issue.  The CPO's differ in the extent of guidance they
give, their scope, and their burden on industry and EPA.  Not all
the options discussed in the draft Regulatory Analysis or the
proposed Economic Impact Analysis are included in the CPO's.
This does not mean, however, that they have been eliminated from
consideration for the final rules.  These CPO's are intended to
serve as examples of possible programs.  They illustrate the
major alternatives that EPA considered in developing proposed
section 5 rules, but they do not represent every combination of
options that the Agency has considered in the past or is now
considering.

     The CPO's, which are discussed more fully in Chapter 5 of
the proposed Economic Impact Analysis, are summarized in Table
III-l.  Based on the level of reporting requirements in each of
the CPO's,  they are referred to in this chapter as:

    •    CPO 1;  Minimum Guidance

    •    CPO 2;  October 16 Reproposal (with processor reporting,
         as proposed in August 1980)

    •    CPO 3;  January 10 Proposal

CPO 2 reflects the program proposed by EPA.  The remainder of
this chapter discusses the advantages and disadvantages of each
CPO, and explains EPA's choice of CPO 2 as the most appropriate
overall program of the three.

     1.  Options Considered

    •CPO 1 — Minimum Guidance

     Under CPO 1, EPA offers the least guidance to industry about
reporting requirements,  and costs of notification to industry
at least initial costs — will probably be the lowest.  Under
this CPO,  EPA would not develop a form, but would give minimum
guidance to submitters about what information they would have to
report.  Test data would be defined as in the "possession or
control" of the submitter if they were in his possession or
control, or in the possession or control of a subsidiary
associated with the submitter in the research, development, or

marketing of the substance.  Submitters would not be required to
contact customers for information.  EPA would have no special
supplemental reporting authority to gather data not contained in
the notice; it could do this only through an individual section
8(a) rulemaking, or in some cases a section 5(e) order.  EPA
could, however, find that a submission did not meet notice
requirements, and the review period would not begin.  EPA would
make these findings on a case-by-case basis and would not publish
formal criteria or procedures.

     Of the three CPO's, CPO 1 offers the greatest protection for
confidential business information, and in most cases it involves
the least cost to the submitter.  At the time of submission, the
submitters would have to substantiate only claims for information
that would appear in the section 5(d)(2) FEDERAL REGISTER
notice.  They would not develop generic names or descriptions
masking confidential information, and no masked information would
be published.  Confidential chemical identity underlying a health
and safety study would be disclosed only after manufacture began.

     Finally, CPO 1 is the narrowest of the CPO's in
applicability.  As under the other CPO's, all domestic
manufacturers would report.  However, only the "principal
importer," not all parties to the import transaction, would be
required to submit notices.  Principal importers would have to
ask foreign suppliers and manufacturers only for health and
environmental effects data and risk assessments.  Persons
manufacturing new chemical substances only for export,  and
persons who processed previously exempt substances for TSCA
commercial purposes, would have to submit a section 8(a) report
rather than a section 5(a)(2) notice.

     CPO 2 — October 16 Reproposal

     CPO 2 consists of the preferred options discussed in Chapter
II of this Regulatory Analysis.  It includes the notice form,
supplemental reporting requirements, customer-information
provisions, and certain aspects of the confidentiality procedures
proposed on October 16; it also includes processor notification
proposed on August 15 and several options from the January 10
proposal that were not reproposed.

     Under CPO 2,  submitters would complete the October 16 notice
form.  They would have to provide test data in the possession or
control of their subsidiaries, their parent companies,  and their
parent companies'  subsidiaries, if these companies were involved
in the research, development, or marketing of the new chemical
substance.  There would be no mandatory customer contact, but
submitters would have to report the number of committed customers

-------
                               -68-
intending to use the new chemical substance in ways not known to
them.  They would also be required to report the percentage of
production volume allocated to these customers during the first
three years of production.

     CPO 2 includes a section 8 supplemental reporting provision,
under which EPA, by letter, could require additional information
from the submitter during the review period.  The procedures and
criteria for this authority would be those proposed on October
16.  Also under CPO 2, if a submission had "major deficiencies,"
EPA could find that it did not meet notice requirements, and the
review period would not begin.  If the submission had "minor
deficiencies," the review clock would stqp until the deficiencies
were corrected.

     The submitter would assert confidentiality claims according
to the procedures in the October proposal.  He would substantiate
all information at the time of submission.  Certain categories of
confidential information would be masked by generic names and
descriptions in public notices; confidential chemical identity
underlying a health and safety study would be disclosed only
after manufacture began.

     The definition of importer would be the same under CPO 2 as
under CPO 1, but no specific party to the transaction would be
named as responsible for reporting.  Instead, all parties would
be responsible for seeing that a notice was submitted.  The
importer would be required to contact foreign suppliers and
manufacturers, and ask them to complete a limited Foreign
Manufacturers/Suppliers Form.  Persons manufacturing a new
chemical substance solely for export would submit a section 5
notice.  Persons intending to process a previously exempt
substance for a TSCA commercial purpose would also be required to
submit a section 5 notice.

     CPO 3 — January 10 Proposal

     In general, CPO 3 requires the most information, and it is
the broadest in scope.  Submitters would be required to complete
the January 10 notice form.  They would have to seek information
from all persons who they had reason to believe would purchase
the new chemical substance.  They would have to provide test data
in the possession or control of their subsidiaries, their parent
companies, and their parents' subsidiaries, whether or not these
companies were involved in the research, development, or
marketing of the new chemical substance.  During the review
period, EPA would have broad supplemental reporting authority, as
proposed on January 10.  Under CPO 3, EPA would stop the review
only if it identified a major deficiency in the submission during
the first 30 days of the notice review period.  Submitters could
appeal an EPA finding that a submission did not meet regulatory
requirements.

-------
                               -69-
     The submitter would claim confidentiality according to the
procedures in the January proposal.  As in CPO 2, he would have
to substantiate all information at the time of submission;
however, the burden would be greater under CPO 3 because in most
cases he would have to answer more substantiation questions.
Again as in CPO 2, he would be required to provide generic names
and descriptions to mask confidential business information in
certain categories.  Confidential chemical identity underlying a
health and safety study would be disclosed at the time of
submission.

     Under CPO 3, all parties to the import transaction, not just
the principal importer, would be responsible for submitting
notices. The importer would have to contact foreign suppliers and
manufacturers and ask them to complete the detailed form proposed
on January 10.  Persons manufacturing a new chemical substance
solely for export would submit a section 5 notice.  Manufacturers
and importers intending to process, use, or distribute R&D or
test-marketed substances in a manner inconsistent with the terms
of the exemption would also submit a notice.  EPA would not
accept notices from other processors, unless they were also
manufacturers of the substance.

     2.  Discussion

     Chapter 5 of the proposed Economic Impact Analysis discusses
in detail the relative costs to industry of notification under
the three CPO's.  The discussion divides costs into presubmission
and postsubmission costs.  Presubmission costs include out-of-
pocket costs and costs of delays; postsubmission costs include
out-of-pocket costs, costs of delays, costs of potential trade-
secret disclosure, and costs of restrictive action.  The
following sections of the Regulatory Analysis compare the CPO's
on the basis of the assessment of costs to industry in the
Economic Impact Analysis, as well as the contractor's and EPA's
assessment of costs to the Agency and the public.

         a.  Reporting and related requirements.   CPO 1 imposes
the lowest initial reporting burden on industry.   Because
submitters receive little guidance, they can notify EPA in the
manner they consider least costly and most expedient.
Furthermore,  the amount of information they provide is limited by
the absence of a customer-contact provision, by the requirement
that foreign manufacturers submit only health and environmental
effects data and risks assessments, and by the narrow definition
of possession or control.

     On the other hand, CPO 1 could involve considerable
postsubmission costs for particular submitters.  Under a minimum
guidance scheme, EPA is likely to receive less information and
will have to contact the submitter more often for additional

-------
                               -70-
information.  This may lead to delay as a result of extension of
the review period under section 5(c).  Without supplemental
reporting, EPA would have to rely on voluntary cooperation,
individual section 8(a) rules, or, in some cases, section 5(e)
orders.  To the extent that EPA. acts under section 5(e) because
it did not obtain sufficient information in the notice form, or
because it had no supplemental reporting procedures, CPO 1 will
impose a high postsubmission burden.  In addition, the absence of
formal, published criteria for determining when a submission does
not meet statutory requirements will increase industry
uncertainty.  Because of this absence, EPA might receive more
incomplete submissions than it would under the other CPO's, or
submitters might provide EPA more information than the Agency
needed for an initial review-

     The minimum guidance approach, as discussed earlier, places
a heavy administrative burden on EPA.  Under the Interim Policy,
which offers minimum guidance, EPA has found that in many cases
it must organize submitted data.  It also expends considerable
resources in obtaining data that might have been submitted at
little cost initially if appropriate instructions had been
provided.  Because of the EPA resources spent in these
administrative and related functions, fewer resources are
available for assessing new chemical substances.  As a result,
EPA reviews may suffer in the long run.

     CPO 2 and 3 provide more detailed guidance to submitters,
and they impose broader reporting requirements.  The use of forms
under these CPO's would considerably ease EPA's administrative
burden and reduce industry uncertainty about what information to
submit.  Standards for section 5 notices would also reduce
uncertainty.  In general, under CPO 2 EPA would receive
information sufficient for an initial screen of new chemical
substances; under CPO 3, it would receive information that could
support detailed review and possibly regulatory action under
section 5(e) or 5(f).  Under CPO 2, the submitter would complete
the limited October 16 form; under CPO 3, the more detailed
January 10 form.  EPA would also receive more information under
CPO 3 than under CPO 2 because it requires more information from
customers and foreign manufacturers, it requires customer
contact, and it defines  "possession or control" more broadly.

     Because CPO 3 requires more information, it will usually
involve greater presubmission costs, while CPO 2 is likely to
involve greater postsubmission costs.  Under CPO 2, EPA will
often have less information on hand in the original submission,
and therefore the Agency is more likely to seek additional
information under the proposed supplemental reporting authority
or, in some cases, section 5(e).  On the other hand, the scope of

-------
                               -71-
the  section 8  supplemental authority  is  more  clearly  defined  in
CPO  2 than in  CPO  3.  For this  reason, the  costs  and  uncertainty
associated with  its use would be  less.

     CPO  2 and 3,  because they  allow  more efficient use of
limited EPA resources and because they provide EPA with
information adequate for an  initial review, will  in the long  run
lead to more reliable reviews than will  CPO 1.  In general, the
more data EPA  has  available, the  better  the review.   At the same
time, however, the more information EPA  receives, the more likely
it is that some  of the information may be unnecessary for the
review.   In this case, submitters have borne  the  cost of
providing information of marginal use to EPA.  For this reason,
EPA prefers the  approach of  CPO 2 to  that of  CPO  3.   CPO 2
requires  less  information in the  notice  by  focusing on the
information needed for an initial review.   In the initial review,
EPA can identify and seek more  data on substances of  high
concern.  This procedure will ensure  a more efficient use of both
EPA and industry resources.

         b.  Confidentiality.   CPO 1  involves the lowest initial
cost for asserting confidentiality, and  it  offers the greatest
protection for confidential  business  information.  However, it
severely  limits public participation  in  the review process.  EPA
would not publish  generic names or descriptions in section
5(d)(2) FEDERAL REGISTER notices,  which  would restrict public
oversight.-  Under  this CPO,  delays in obtaining substantiation
for other information will also restrict public participation in
the review process.

     Although  the  presubmission costs of CPO  1 may be low for the
submitter, it will have the highest postsubmission substantiation
costs.  Under  this CPO,  the  submitter will often have to
substantiate information not substantiated when the notice was
submitted — for example, if a Freedom of Information Act (FOIA)
request is received.   Since the premanufacture review program
began, public  interest groups have regularly  requested
premanufacture notices under the  Freedom of Information Act.
Therefore, under CPO 1,  submitters are likely to have to
substantiate confidentiality claims weeks or  months after the
submission of a notice,  when they may no longer be as familiar
with its contents.   Also, because substantiations must be
submitted promptly in response to an  FOIA request, they will be
more burdensome than substantiations  at  the time of notification.

     CPO 2 and 3 will involve greater initial costs for
confidentiality claims.   Submitters will have to develop generic
names and descriptions for certain categories of confidential
business information,  and they will have to substantiate all

-------
                               -72-
claims at the time of submission.  The burden of substantiation
under CPO 2, however, will be considerably less than under CPO 3,
because CPO 2 reduces the number of questions the submitter must
answer in substantiating claims for most types of information.

     CPO 2 and CPO 3 will entail a greater risk of disclosure of
confidential business information because EPA will receive more
information.  In general, the more information that is submitted,
the more information that is subject to disclosure.  Also, under
CPO 3 confidential chemical identity underlying a health and
safety study will be disclosed at the time of submission.

     Although CPO 2 and CPO 3 involve higher presubmission costs
than CPO 1, their postsubmission costs may be lower.  If a
Freedom of Information Act request is made for information
claimed confidential in a notice, the submitter will have already
substantiated his claims.  Also, CPO 2 and CPO 3 will allow
meaningful public participation, both because generic information
will be available to the public and because EPA will review
substantiation claims at the time of notification.  EPA response
to Freedom of Information Act requests will not be delayed by the
substantiation process.

         c.  Applicability.  Of the three CPO's, CPO 1 is the
narrowest in applicability.  All require domestic manufacturers
to report.  However, under CPO 1, only the "principal importer"
need submit a notice; CPO 2 and 3 make all parties to the import
transaction responsible for notification.  Because several
importers will be involved in the submission under CPO 2 and 3,
the overall costs of submission under these options are likely to
be higher for importers.  However,  the costs may be shared among
the parties, and therefore involve little cost for each.
Submission costs for foreign manufacturers and suppliers will be
least under CPO 1 because importers of new chemical substances
must ask them only to supply health and environmental effects
data and risk assessments.  Under CPO 2 and 3, importers must ask
for considerably more information.   Under all the CPO's, however,
submissions by foreign manufacturers and suppliers are voluntary.

     Under CPO 1, persons manufacturing a new chemical substance
solely for export submit a section 8(a) rather than a section 5
notice.  Because of the small business exemption in section 8(a),
companies with annual sales of below $1 million would not
report.  Under CPO 2, exporters submit the October 16 form; under
CPO 3,  they submit the January 10 form.  Because the section 8(a)
form would require the same information as the October 16 form,
presubmission costs of supplying the information would be
approximately the same under CPO 1 as under CPO 2 (except for
small businesses, who would not report under CPO 1).  Other costs
associated with CPO 2 — for example, the broader definition of
possession and control — would make the overall costs of

-------
                               -73-
compliance higher.  For exporters, presubmission costs of CPO 3
are highest.  However, as described in the section on reporting
requirements, CPO 3 is likely to involve lower postsubmission
costs than CPO 2.  CPO 1 will have the lowest postsubmission
costs of the three, because EPA will receive section 8(a) notices
from exporters and, therefore, will not be able to extend the
review period under section 5(c) or act under section 5(e) or
5(f).  In this option, EPA could only act under section 4,
5(a)(2), 6, or 7.  Because of the burden of these actions, they
would be more difficult for EPA to take.

     Under CPO 1, processors of previously exempt substances for
TSCA commercial purpose would submit a limited 8(a) report. CPO 3
requires manufacturers and importers to notify EPA if they
process an R&D or test-marketed substance for purposes
inconsistent with the exemption; under CPO 2, all persons who
process exempt substances for TSCA commercial purposes must
submit a section 5 notice.  Because the section 8(a) form
requires the least information, submitters under CPO 1 will incur
the lowest reporting costs.  Submitters under CPO 3 will incur
the highest costs because the January 10 form is required, and
because the other notification costs associated with this CPO are
highest.

     3.  Preferred CPO
     EPA believes that CPO 2 strikes an appropriate balance
between the burden it imposes on the chemical industry and the
needs of EPA and the public.  This program will establish clear
notification and review procedures, and it will ensure that EPA
receives adequate information for an initial review of new
chemical substances.  Supplemental reporting will allow EPA, when
necessary, to obtain information on substances undergoing
detailed review.  By concentrating its efforts on substances of
high concern, EPA will use its resources most efficiently,
without imposing unnecessary reporting burdens on industry.  The
confidentiality policy will allow the greatest degree of public
participation while still protecting confidential business
information.  In this policy, EPA has provided strong protection
for traditional trade secrets, while allowing greater public
disclosure of health and safety data  — information important to
public participation in the review process.

     CPO 1 has the advantage of allowing the submitter maximum
flexibility; it generally imposes the least reporting burden; and
it involves the least risk of disclosure of confidential business
information.  EPA, however, did not propose this option for
several reasons.  CPO 1 involves the highest degree of
uncertainty for the chemical industry, particularly because  it

-------
                               -74-
provides minimum guidance on reporting  requirements.   In
addition, it offers the least protection to the public,  not only
because its confidentiality procedures  will make public
participation difficult, but also because EPA will  find  it
difficult to perform adequate reviews within the short time
allowed by the Act.  The Agency will not receive enough
information for the initial review of many new chemical
substances, and it will not have procedures adequate  for
gathering this information during the review period.

     CPO 3 will provide EPA with the most information.   This is
an advantage because, on the whole, the  more information EPA has
available to it during the review period,  the more  reliable its
reviews will be.  In addition, CPO 3 will allow the greatest
public participation.  This option, however,  will also impose the
highest overall cost on industry.  EPA believes that  these costs
can be significantly reduced without substantially  reducing the
effectiveness of the program.  The January 10 notice  form,  the
broad definition of possession or control,  the customer-contact
requirements, and other elements of CPO  3  will in many cases
provide EPA with more information than  it needs for an initial
screen.  In CPO 2,  the Agency has reduced these burdens,  while
retaining adequate safeguards.  Of the  three program  options,
therefore,  CPO 2,  the option EPA has proposed,  provides  the
greatest protection for human health and the environment
consistent with the needs and concerns of  the regulated  industry.

 16. Abstract (Limit: 200 words)
   Section 5 of  the Toxic Substances Control Act  (TSCA)  requires
   manufacturers and importers  to notify  EPA 90 days before  they
   manufacture or import a new  chemical substance.   New substances are
   those that are not  on the TSCA Chemical Substance Inventory, which was
   first published on  June 1, 1979,  and supplemented on July 30, 1980,  by
   a Revised Inventory.   EPA proposed regulations  to implement section
   5 requirements and  to establish premanufacture  notice and review
   procedures in the Federal Register of  January  10, 1979  (44 FR 2242),
   October 16, 1979  (44  FR 59764),  and August 15,  1980 (45 FR 54642).   In
   this draft Regulatory Analysis,  EPA explains the  rationale for its
   proposal.  The Regulatory Analysis also discusses the major issues
   raised by the proposed rules and describes the  different  alternatives
   the  Agency considered for resolving the issues.   The analysis is  in
   part based on the proposed "Economic Impact Analysis of Proposed
   Section 5 Notice Requirements,"  prepared by ICF Incorporated of
   Washington, D.C.
