         INSTRUCTIONS FOR REPORTING FOR THE PARTIAL UPDATING
              OF THE TSCA CHEMICAL INVENTORY DATA BASE

                        (INVENTORY UPDATE RULE)
                             I. INTRODUCTION
      The Environmental Protection Agency (EPA) in 1986 promulgated a rule, often
referred to as the  Inventory Update Rule, for the partial  updating of the TSCA
Chemical Inventory data base.  The rule requires manufacturers and importers of
selected chemical substances included on the TSCA Chemical Substance Inventory
to report current data on the production volume, plant site, and site-limited status of
these substances. The  rule was promulgated under the authority of section 8(a) of
the Toxic Substances Control Act (TSCA), and is codified in Subpart B of Part 710 of
Title 40 of the Code of Federal Regulations (40 CFR Part 710).

      Reporting under the Inventory Update  Rule takes place at four-year intervals
which began in 1986.  These instructions pertain to reporting during 1994.

      This booklet  provides  detailed  instructions  and  examples to  assist
manufacturers and importers in reporting under the Inventory Update Rule.  These
instructions, however, are not a substitute for the rule. Manufacturers and importers
of chemical substances should carefully review the Inventory Update  Rule to
determine whether they are subject to its reporting requirements and what information
is to be reported.

      Persons reporting under the Inventory Update Rule  should have a thorough
understanding of the scope and  organization of the TSCA Chemical Substance
Inventory and of the criteria used to determine whether a substance belongs on the
Inventory. Information on the scope and organization of the Inventory can be found
in the  introductory pages of the  1985  edition of the Inventory and in  the 1990
Supplement to the Inventory. Subpart A of 40 CFR Part 710 prescribes criteria for
inclusion of a substance on the Inventory.

      See Section  V (page 27) for instructions on how  to obtain copies of the
Inventory and of  TSCA  regulations.
IUR1994

-------
     II. DETERMINING THE SUBSTANCES FOR WHICH YOU MUST REPORT
      To ascertain your reporting obligations, you must make two determinations for
each chemical substance that you manufacture in the United States or import into the
United States:

      1)     Is the substance reportable under the  Inventory Update Rule?

      2)     Are you a manufacturer, importer, or exporter who is required to report
            that substance?

A.    Reportable substances.

      To be reportable under the Inventory Update Rule, a chemical substance must
meet two requirements:

      1)     The substance must be on the TSCA Chemical Substance Inventory as
            of August 25, 1994; and
                                                 ^
      2)     The substance must not be of a type  exempt from reporting under the
            Inventory Update Rule.

      1.     Inventory substances. The TSCA Chemical Substance Inventory is a list
of chemical substances distributed in commerce in the United States.  The Inventory
was originally  compiled from reports submitted by manufacturers, importers  and
certain processors in  1978 and 1979.  New chemical substances are added to the
Inventory when companies who have submitted Premanufacture Notifications (PMNs)
or Polymer Exemption Applications to EPA under section 5 of TSCA notify the Agency
that manufacture or import of the chemical substance has commenced.

    EPA keeps  a Master Inventory File, which is the authoritative list of all the eligible
chemical substances which have been reported to EPA for inclusion in the Inventory.
EPA also makes available both in printed and computer-readable form a public version
of the Inventory, referred to as the Public Inventory. The Public Inventory does not
contain the  specific identities of chemical substances whose identities have been
claimed as confidential business information (CBI).  The printed version of the Public
Inventory does contain generic chemical names for these CBI chemical substances.
However, the computer-readable version does not. The Public Inventory has been
updated several times both in print and computer-readable form. The most complete
edition of the printed version of the Public Inventory was published in 1985, and a
1990 supplement to the 1985 edition is also available.  The computer-readable
version of the Public Inventory is being updated biannually. Additionally, EPA will  also
be making available to the public a PC readable version before the commencement of
the reporting period,  as referenced in the Federal  Register announcement for the
 IUR1994                                                              Page 2

-------
reporting period. See Section V of these instructions (page 27) for information on
obtaining copies of the Public Inventory.

      2.     How  to determine whether a  chemical  substance is  listed  on the
Inventory.  Many companies  have already  determined that the substances they
manufacture or import are on the Inventory.  You may have been able to make such
a determination  if:

      1)     you have located the substance in the Public Inventory;

      2)     you reported the substance to EPA under the Inventory reporting rule in
            1978 or 1979 or as an Inventory correction;

      3)     in response to a PMN, Test Market Exemption Application,  bona fide
            request, or other communication the Agency has informed you that the
            substance is on the Inventory; or

      4)     you have submitted  a Notice  of  Commencement of manufacture or
            import for a PMN  substance.

      If you do not already know whether a substance you manufacture or import is
on the Inventory, you should consult a  copy of the  latest public version  of the
Inventory (see Section V, below, for  instructions on how to obtain a copy).  The
Public Inventory provides detailed information on the organization of the Inventory and
on how substances are named and listed.

      Several commercial databases  have  incorporated the public version  of the
Inventory (which does not include substances with confidential identities) and indicate
whether a given chemical substance is included on the Inventory.  EPA can guarantee
neither the currency nor the accuracy of the information on these databases; however,
there is no penalty for reporting a substance which is not required to be reported.

      If at this  point you know that your substance is on the Inventory, you may
proceed to Section 11. A. 2. (page 3) to determine whether it is of a type exempt from
reporting under the Inventory Update Rule.

      If after having checked the above sources you are still uncertain as to whether
a chemical substance is listed on the Inventory, you should write to EPA at the
following address:

                 OPPT Document Control Officer
                 U.S. Environmental Protection Agency
                 Office of Pollution  Prevention and Toxics  (7407)
                 401  M Street, S.W.
                 Washington, DC 20460
                 ATTN: Inventory Update Rule/Bonafide
IUR1994                                                                Page 3

-------
   Your letter should request that EPA search the  Master Inventory File, including
confidential substances, to determine whether the  substance is listed.  You must
substantiate the fact that you are actually manufacturing or importing the substance
in question by providing the following information:

      1)   company identification, address, and telephone number;

      2)   the specific chemical identity of the substance,  preferably a Chemical
           Abstracts Service Preferred or Index Name, a Chemical Abstracts Service
           Registry Number (if available), and a structural diagram (if available);

      3)   a statement  signed  by  a  company  officer that  your company is
           manufacturing and/or importing the chemical substance for commercial
           purposes;

      4)   a statement  signed  by  a  company  officer that  your company is
           requesting this search pursuant to the Inventory  Update Rule; and

      5)   an elemental analysis of the substance.

      You may claim information in your letter as confidential by circling or bracketing
the text to be protected and marking "CONFIDENTIAL"  on  each  page containing
confidential information. Failure to so mark this information may result in EPA making
the information available to the public without further notice to you.

      Note that this  procedure  is  similar  but not identical to  EPA's bona fide
procedure codified in 40 CFR §710.7(g) and §720.25(b). If you intend to. but do not
currently manufacture or import a substance  for commercial purposes and need a
search of the  Master Inventory File, you must follow the procedures codified in those
sections.

      EPA's response will inform the manufacturer or importer whether the chemical
substance is on the Inventory and whether the substance is subject to reporting under
the Inventory Update  Rule.

      If the chemical substance is found on the confidential Inventory, EPA will notify
the person(s)  who originfHy reported the substance that another person has requested
information pursuant to the Inventory Update Rule procedures,  and therefore was told
that the chemical substance is  on the Inventory and that it is  subject to reporting.
                                                               t
      If you  are  an importer and cannot provide  all of  the required information
because your foreign manufacturer/supplier is  maintaining it as  confidential, the
manufacturer/supplier can send the information directly to EPA. Be advised that it is
the obligation of the importer to insure that the foreign manufacturer complies with
the requirements of the IUR.
 IUR1994                                                               Page 4

-------
      Because searches of the Master Inventory File require a considerable amount
of time to process, you are urged to request such a search only if your search of the
public version of the Inventory, commercial databases, and your company's records
fails to resolve your question.  Moreover, if your request  is not  received prior to
October 25, 1994, EPA cannot guarantee that you will receive a response in time for
you to complete the reporting form before the end of the reporting period.

      3.     Excluded  substances. Four categories of substances, though included
on the Inventory, are largely excluded from reporting under the Inventory Update Rule.
These categories are polymers, inorganic substances, microorganisms, and naturally
occurring substances.  Refer to section 710.26 of the Inventory Update Rule and to
the  preamble of the Federal Register notice announcing  the rule (51  FR 21438) for
precise definitions of these categories.

      The Inventory Update Rule definition of polymer is sufficiently broad to include
virtually all those substances that are generally considered polymers. These include
polysaccharides such  as agar and gums, and all classes of proteins, enzymatic or
structural.  However, substances which result from hydrolysis, depolymerization, or
chemical modification of polymers such that the final products are no longer polymeric
(e.g., a mixture of amino acids which is the result of hydrolysis of a polypeptide) are
not considered to be polymers, and must be reported if not otherwise excluded. For
reporting purposes, salts of polymers are also considered to be polymers.

      a.     Determining whether a substance is excluded. To assist  in identification
of excluded substances, most of these substances are labelled in the  printed and
computer-readable versions of the Inventory with  an "XU" flag.  However, due to
difficulties  in developing a computer algorithm for identifying all such substances in
the Inventory,  EPA was not able to  flag  all excluded  substances.   For example,
inorganic substances and biopolymers found in the UVCB Index section of the Public
Inventory (chemical substances of unknown or variable composition, complex reaction
products, and biological materials) are frequently not labelled with an XU flag.

      A  few of the polymerization gases which are not considered  to be polymers
might have been incorrectly flagged because of the inclusion of the word "polymer"
in the chemical name.  These substances are nevertheless reportable under the IUR.

      Submitters are  advised to utilize the flag only as a guide: submitters will be
responsible for verifying exemptions.  If a  substance does not bear  an  XU flag and
section 710.26 of the Inventory Update Rule does not provide sufficient guidance to
determine whether the substance is excluded, you may request assistance from EPA
(see Section VI, below, for inquiries).  In addition, the following substances, though
not flagged with the XU designation, nonetheless belong to a category excluded from
Inventory Update Rule reporting:
 IUR 1994                                                                Page5

-------
                 Name                   CAS Registry Number

                 Carbon black            1333-86-4
                 Carbon                 7440-44-0
                 Graphite                7782-42-5
                 Charcoal                16291-96-6

      b.     When an excluded substance must still be reported. With the exception
of naturally occurring substances, a chemical substance which falls into one of the
excluded categories must still be reported if it is the subject of a rule proposed or
promulgated under section 4, 5(a)(2), 5(b)(4), or 6 of TSCA, of an order issued under
section 5(e) or 5(f), or of relief which has been granted under a civil action under
section 5 or 7.   A list of all substances which fall  into one of these categories is
contained in Appendix A at the back of these instructions. However, if you are unable
to determine whether the specific chemical substance you manufacture falls within
one of the generic chemical names listed in the appendix, you may ask EPA whether
the specific substance is reportable by following the procedures outlined on page 3
of this manual.

B.    Determining whether you are a manufacturer or importer who is required to
      report a substance.

      Even if you manufacture or import a substance reportable under the Inventory
Update Rule you may be exempt from the reporting requirements for that substance.
Questions relevant to whether you must report include:

      1)     Did you manufacture or import 10,000 pounds (4,540 kilograms) or
            more of the reportable substance at any single site during the corporate
            fiscal year immediately preceding  the reporting period?

      2)     Do you qualify as a small manufacturer with respect to the substance?

      3)     Did you   manufacture  or  import  the reportable  substance under
            circumstances which do not require reporting?
      1.    Manufacture or import of 10.000 pounds or more.

      a.    Manufacturers and Importers.  Reporting for the Inventory Update Rule
is done by individual site of manufacture or by the organizational site which controls
importation.   For  the  purposes  of the  following discussion,  manufacturers  and
importers are treated separately.

      Manufacturers.  A manufacturer is defined at 40 CFR §704.3.   The word
"manufacture" is defined at 40 CFR section 710.2{o) and also at 40 CFR section
704.3.
 IUR1994                                                               Page 6

-------
      Importers.  The site of importation is  defined in section 710.28(c) of the
Inventory Update Rule as the site of the operating unit which is directly responsible
for importing the substance and which controls the import transaction.  In some cases
this may be the site of your headquarters, in others a specific plant site or a broker.

      Importers under TSCA are defined in 40  CFR §704.3 and §710.2(1).  Although
for a given substance that your company is importing at a given site more than one
person may meet the criteria in sections 704.3 and 710.2(1), only one should report.

      Exporters.   A  manufacturer  of an   IUR  reportable chemical  substance
manufactured solely for export is required to report and otherwise comply with all IUR
requirements applicable to manufacturers of all IUR  reportable chemicals.

      b.    Meeting the 10.000 pound annual production volume threshold.

      Reporting is  required for a chemical substance only if you manufactured or
imported 10,000 pounds (4,540 kilograms) or more of the substance at any single site
you owned or controlled during the corporate  fiscal year immediately preceding the
reporting period (see Section III.B., below, for more information about fiscal year).
Moreover, if during the year you manufactured 10,000 Ibs. or more of the substance
at some sites  and less than  10,000  Ibs.  at  other sites, you  need to report the
substance only for those sites at which you manufactured or imported  10,000 Ibs. or
more.

      Companies that both manufacture and import the same substance.   Such
companies should add the manufacturing and importation volume at each site (see
above to determine site  of importation) to determine whether the 10,000 pound
threshold has  been met.   For example,  if you  manufacture 5,000 pounds of a
reportable substance and import  6,000 pounds, you should report.

      Substances in a mixture. Although mixtures  as defined in 40 CFR §710.2(q)
are not  reportable, the chemical substances  of which a mixture is  comprised are
reportable.   If you manufacture the substances as part of a mixture, you  must
determine for each substance in the mixture whether the production volume was over
10,000  pounds.  Similarly, if you import a mixture you must determine for each
substance in the mixture whether its importation volume was 10,000 pounds or more.
Note that a person  who creates a mixture by combining existing substances without
a chemical reaction is not a manufacturer of those substances and therefore does not
report those substances under the Inventory Update Rule.

      Recordkeepina requirement.  Even if you manufacture/import less than 10,000
pounds of a reportable substance at a  site, you must maintain records documenting
that fact (see Section IV.G. below, page 25).

      2.    Small Manufacturers.  (For the purposes of the following discussion, the
term  "manufacturers" refers to  both  manufacturers  and  importers.)    Small
IUR 1994                                                               Page 7

-------
manufacturers are usually exempt from reporting under the Inventory Update Rule (but
see below for a discussion of when small manufacturers are not exempt). You qualify
as a small manufacturer if you meet either one of the following tests:

      1)     If your total annual sales, combined with those of your parent company,
            domestic or foreign (if any), do not exceed $4 million,  regardless of
            annual production volume you qualify as a small manufacturer.

                                     or
      2)    If your total annual sales, combined with those of your parent company,
            domestic or foreign (if any), are less than $40 million, you qualify as a
            small manufacturer with respect to a particular substance for those plant
            sites at which the annual production volume of the substance does not
            exceed 100,000 Ibs.  If the annual production volume of the substance
            at any of your sites is over 100,000 Ibs., you are required to report only
            for  those sites.    Note that it  is  possible to  qualify  as a  small
            manufacturer with respect to some substances and not others, or some
            plant sites and not others.

See  40 CFR §704.3  for a more  complete discussion of the small manufacturer
exemption.

      When a small manufacturer must still report. Even if you qualify as a small
manufacturer you must still report if you produced 10,000 Ibs. or more of a reportable
substance which is the subject of (1) a rule proposed or promulgated under section
4, 5(b)(4), or 6 of TSCA, (2) an order under section 5(e), or (3) relief granted under
a civil action under section 5 or 7. A list of all substances which fall into one of these
categories is contained in Appendix A.

      3.    Additional reporting exemptions.  Persons who manufacture or import
reportable substances under the following circumstances are not required to report for
those substances under the Inventory Update Rule:

      1)    The chemical substance is  manufactured or imported solely in  small
            quantities for research and development.

      2)    The chemical substance is imported as part of an article.

      3)    The chemical substance is manufactured as an impurity, byproduct, or
            non-isolated intermediate, or in a manner incidental to another operation
            or upon end use of another substance or mixture, as described in 40 CFR
            §720.30(g) and (h) (see 48 Fed. Reg.  21746, May  13, 1983).
 IUR1994                                                              PageS

-------
      4)     All the information required by the Inventory Update Rule was reported
            to EPA pursuant to a rule under section 8(a) of TSCA between August
            25, 1993 and August 24, 1994.

      Articles. An article is defined in 40 CFR §710.2(f) as "a manufactured item (1)
which is formed to a specific shape or design during manufacture, (2) which has end
use function (s) dependent in whole or in part upon its shape or design during end use,
and (3) which has either no change of chemical composition during its end use or only
those changes resulting in compositions which have no commercial purpose separate
from that of the article and that may occur as described in section 710.4(d)(5), except
that fluids and particles are not considered articles regardless of shape or design."

      EPA considers imported items as articles if they are manufactured in a specific
shape or design for a particular end use application, and this design is maintained as
an essential feature in the finished product. Thus, materials such as metal  or plastic
sheets, wire, coated fabric, rolled  carpet, sheets of plywood and other similar
materials will be viewed as articles by EPA, even if, for example, subsequent to import
they are rolled or drawn thinner, cut,  printed, laminated, or thermoformed, so long as
they meet the above criteria.  Substances which are part of such articles are not
subject to reporting under the Inventory Update Rule.

      If an item is manufactured in  a particular shape for the purpose of shipping
convenience and the shape has  no function in the end use, it would not be considered
an article. Thus, chemical substances which are part of items such as metal ingots,
billets, and blooms are subject to reporting under the Inventory Update Rule.

      Duplicative reporting unnecessary.  If between August 25, 1993 and August
24, 1994 you submitted the information  required by the Inventory Update Rule in
response to another rule promulgated under section 8(a) of TSCA (e.g. the Preliminary
Assessment Information Rule, 40 CFR  §712,  Subpart B, or the Comprehensive
Assessment Information Rule,  40 CFR §704, Subpart D), you are not required to
report under the Inventory Update Rule for the same substance during 1994.

C.    Decision making flow chart.

      The following flow chart summarizes the questions which must be  answered
to determine your reporting obligations for a  particular substance.  (For simplicity's
sake, not all reporting exemptions are included in  the flow chart.)

-------
D.    Manufacture or importation of chemical substances subject to TSCA but not
      included on the Inventory.

      When checking the chemical substances you manufacture or import against the
TSCA Chemical Substances Inventory you may discover that you are manufacturing
or importing substances which are not on the Inventory but which should have been
reported to EPA and never were. Such manufacture or importation is in violation of
section 15 of TSCA and could subject you to administrative or criminal penalties.

      Note that hydrates are not listed  on the Inventory. You are required to report
the CAS Registry number of the corresponding anhydrous form. Adjust the reported
production volume to exclude water.

      If you are manufacturing or importing a substance which was previously on the
Inventory but which has subsequently  been delisted, then you are in violation and
must follow the directions below.

      If you find  that you have or may  have  manufactured  or imported chemical
substances in violation of TSCA, you should contact the Agency  at the following
address:

           Director
           Toxics and Pesticides  Enforcement Division
           Office of Regulatory Enforcement (2245)
           U.S.  Environmental Protection Agency
           401 M Street, S.W.
           Washington,  D.C.  20460

      Information in your  letter may be  claimed  as  confidential  by  circling or
bracketing the text to be protected  and  marking the page, "CONFIDENTIAL."  Failure
to so mark this information may result in EPA making the information available to the
public without further notice to you.

      Significant reductions in penalties are given for persons voluntarily disclosing
violations.  Note, however, that  continued manufacture or importation of such
chemical substances remains illegal even after you have contacted the Agency, until
the requirements of TSCA have been met.
IUR 1994                                                               Page 11

-------
                        III. WHEN YOU MUST REPORT
      The Inventory Update Rule establishes reporting periods every four years. The
first reporting period was during 1986; the second was during 1990; the third period
is during 1994. A reporting period serves two functions:

      1)    It is a 120-day period during which reports for the Inventory Update Rule
            must be filed.

      2)    It is used to determine the applicable fiscal year for calculating annual
            production volume.

A.    You must report during the 120-day reporting period.

      The next reporting period begins August 25, 1994  and ends December 23,
1994.  All submissions must be postmarked no later than December 23, 1994.  If you
are required to report (see Section II., page 2), failure to file your report during this
period is a violation of section 15 of TSCA.

      Persons requesting searches of the Master Inventory File (see Section H.A.2.,
page 2,  3) must  make their requests at least 60 days prior to the close of the
reporting period.  If you have made your request in time you will be allowed 15
business days from the date of receipt  of  EPA's answer or until  the end of the
reporting period, whichever is later, to submit the report for the substance which was
searched. Any other reports received  after the end of the reporting period will be
considered late and will be subject to enforcement action.

B.    Determine annual production using the reporting period as a reference point.

      To determine whether you manufactured or imported 10,000 Ibs. or more of
a reportable substance at a site, you must determine your total manufacture/import
volume for your last corporate fiscal year which ends prior to August 25, 1994.  For
example,  someone   whose fiscal  year  is  the  calendar year  would  determine
manufacture or import volume for the period January 1, 1993 - December 31,1993,
while someone whose fiscal year is July 1  to June 30 would determine manufacture
or import volume for the period July 1, 1993  to June 30,  1994.

      Note that even though you may be exempt from reporting a chemical substance
during one reporting period because you manufactured or imported less than 10,000
Ibs. during the applicable fiscal year, you may be required to report it during the next
reporting period if during the next applicable fiscal year the production volume
increases to 10,000 Ibs. or more.
 IUR1994                                                             Page 12

-------
                            IV.  HOW TO REPORT

A.    Form of submission.

      Information reported for the Inventory Update Rule must be submitted either on
Form  U or by electronic means (see subsections C., page 15  and D. page 23).
Separate forms are required for each plant site.

      For the  1994 reporting period, Form U has been made readable by Optical
Character Recognition (OCR) technology. OCR is an electronic data entry means that
will help ensure  that the information submitted for the IUR will be correctly and
quickly entered into the data base. In OCR, a light beam is passed over the paper,
and the information on the page is 'recognized' as text. This process requires that the
text be  typed  (or written very clearly in capital letters), so that the  machine can
properly recognize the characters on the form.  You may only use an original form for
reporting.

B.    Confidentiality.

      Information submitted to EPA under the Inventory Update Rule may be claimed
as confidential business information (CBI) by checking the appropriate "CBI" boxes on
Form  U.  Claims  of confidentiality will not be accepted and honored if they are not
asserted at the time information  is submitted to EPA or  submitted  in a  manner
inconsistent with the rule and reporting  instructions.

   You may assert a CBI claim for the specific identity of a chemical substance only
if EPA treats that substance identity as confidential on the Inventory at the time your
report is  submitted (i.e.,  the  substance is  not  on the Public  Inventory).  Both
confidential and non-confidential substances may be reported on the same form, and
confidential substances may be included in diskette submissions.

      If you are manufacturing or importing a chemical substance which is currently
listed  on the Inventory as confidential you are encouraged not to assert confidentiality
claims if circumstances are now such that confidentiality is no longer necessary. If
you report a previously confidential substance as non-confidential (see subsection C,
below, for specific instructions) that substance will subsequently be  listed on  the
Inventory as non-confidential.

      No CBI claim for chemical identity will be accepted unless accompanied by a
separate written substantiation for each chemical substance claimed as CBI, with
detailed  answers to the eleven questions prescribed in  section  710.38  of  the
Inventory Update Rule, and repeated below.  The answers must be complete and
specific to the chemical substance in question. The substantiation must be dated and
signed by an  officer of the  company.  If  the  required substantiation does  not
accompany your Form U, EPA may make the chemical identities reported on the form
available to the public without further notice to you.
IUR 1994                                                                Page 13

-------
      Information In a substantiation may itself be claimed as CBI by circling  or
bracketing  the text you  wish to claim as  confidential  and marking  the  page
"CONFIDENTIAL." Failure to so mark this Information may result In EPA making the
Information available to the public without further notice to you.

      The eleven questions to be answered In the substantiation are:

      1)     What harmful effects to your competitive position, If any, do you think
would result from the Identity of the chemical substance being disclosed in connection
with reporting under this subpart?

      2)     How long should confidential treatment be given? Until a specific date,
the occurrence of a specific event, or permanently? Why?

      3)     Has the chemical substance been patented?  If so, have you granted
licenses to others with respect to the patent as It applies to the chemical substance?
If the chemical substance has been patented and therefore  disclosed  through the
patent, why should it be treated as confidential?

      4)     Has the identity of the chemical substance been kept confidential to the
extent that your competitors do not know it is being manufactured or Imported for a
commercial purpose by anyone?

      5)     Is the fact that the chemical substance Is being manufactured or Imported
for a commercial purpose publicly available, for example In technical Journals, libraries,
or State, local, or Federal agency public files?

      6)     What measures have you taken  to prevent undeslred disclosure of the
fact that this chemical substance is being manufactured or imported for a commercial
purpose?

      7)     To what extent has the fact that this chemical substance is manufactured
or imported for commercial purposes been revealed to others? What precautions have
been taken  regarding these disclosures?  Have there been public  disclosures  or
disclosures to competitors?

      8)    Does this particular chemical substance leave the site of manufacture In
any form, as product, effluent, emission, etc.? If so, what measures have you  taken
to guard against discovery of Its identity?

      9)    If the chemical substance leaves the site in a  product that is available to
the public or your competitors, can the substance be Identified by analysis of the product?

      10)   For what purpose do you manufacture or Import the substance?
 IUR1994                                                              Page 14

-------
      11)   Has EPA,  another Federal agency,  or  any Federal  court made any
pertinent confidentiality determinations regarding this chemical substance?  If so,
please attach copies of such determinations.

C.    Completing Form U.

      1.     Report only using original copies of Form U.

      Each copy of Form U bears an Individual report number, and is readable by
optical character recognition (OCR) technology.   Do not report on a photocopy of
Form  U,  because It will not have a unique  report number and will not be OCR-
readable.  See Section V (page 27) for  obtaining copies of Form U.

      2.     Certification Statement.

      a.     Signature. The certification statement must be signed by an officer of
the company.  This statement certifies  to the truth and accuracy of the Information
reported and of the confidentiality claims made on the form (see the back of Form U
for details). Note that by certifying the truth and accuracy of the information on the
form,  you acknowledge that any knowingly false or misleading statement may be
punishable by fine or Imprisonment or both under applicable law. Sign in black ink to
ensure that the form bears a legible signature which can be microfiched or otherwise
archived.

      b.     Date.  Enter the month, day, and year that the form was signed.

      c.     Name and Title. Enter the name  and title of the person who signed the
certification statement.

      3.     Technical Contact and Company Information.

      a.     Technical Contact Name. Enter the name of  the person whom EPA may
contact  for clarification of  the information submitted on  Form U.  The  technical
contact need not be located at the site  for which information is reported, but should
be located In the U.S.  If you wish to identify more than one  person as a technical
contact, please Include the extra name(s) In a separate cover letter.

      b.     Qpmpany Name. Address Line I. Address Line II. Telephone Number. Use
this block to enter the company name and  street address.   Please use standard
addressing techniques as established by the  U.S. Postal Service.  Post office box
numbers are only acceptable if also accompanied by a street address. If a post office
box Is listed, It should be listed after  the street  address on  Address Line II. The
telephone number listed should be that of the technical contact.

      c.     CBI. Checking the CBI box In this  block asserts a confidentiality claim for
the link between your company and all the chemical substances reported on the form.
IUR1994                                                               Page 15

-------
Checking other CBI  boxes on the form will not protect this link.  If there are some
substances whose connection  to your company you do not require to be kept as
confidential, report those substances on a separate form on which the CBI box in the
Company block is not checked.

      4.     Plant Site Information.

      Reporting under the Inventory Update Rule is done by individual site. Therefore
all the substances reported on one form must be manufactured/imported at the same
site. Enter the name, street address, and Dun & Bradstreet number of the site here.
The plant site name should be  listed as a concatenation of the company name and
plant site name (e.g., Acme Intl-Madison Pit).  (See sample form on page 18)

      a.     Dun & Bradstreet Number. Dun & Bradstreet gives separate numbers to
plant  sites and parent companies; make  sure that the number you  provide EPA
belongs to the individual plant site for which you are reporting. If the plant site does
not have a Dun & Bradstreet number, a Dun & Bradstreet number assignment can be
requested from your local office of Dun &  Bradstreet.  Dun & Bradstreet does not
charge for this service, and does not require that you  disclose  sensitive financial
information  in order to get a  number.  Do not report  the headquarters Dun and
Bradstreet number unless the reporting site corresponds to that number.

      b.     Address. A street address, including Zip code, must be reported.  Post
office box numbers  are not acceptable. If the site does not have a street address,
please provide what descriptive site information you have, including the Zip code.

    See Block G, below, concerning CBI claims for the link between plant site identity
and individual substances.

      5.     Chemical Substance Identitv/Activitv/Confidentialitv.

      a.     Line Number (block A). This part of the form is divided into ten lines to
allow reporting of up to ten chemicals per form.  Each line should represent one
chemical.  If the chemical identity will not fit on one line, rather than using a second
line, you should truncate  the  name with  the use of an ellipsis (...) indicating  an
omission of letters or words,  (e.g.,  utilize  the  available space and if  you can not
include the complete name, end it with a series of full stops or period dots.)

      b.     CAS Registry or Other Identifying Number. Every chemical substance
reported on  Form U must be accompanied by its Chemical Abstracts Service (CAS)
Registry Number (see lines 1, 8, and 10 of sample form) or other identifying number.
The printed  edition of the Inventory contains detailed instructions on how to locate
the CAS Registry Number for a substance  listed therein. When you report a CAS
Registry Number, please  verify that the number you are reporting is the correct
number for your substance.
 IUR 1994                                                              Page 16

-------
      You may be unable to find a CAS Registry Number in the Public Inventory either
because the substance is listed as confidential (in which case the specific identity is
not present and the chemical substance has an Accession Number rather than a CAS
Registry Number) or because the substance was not on the Inventory as of the date
of printing. If this is the case you may use one of the following acceptable identifying
numbers:

            1)    EPA Accession Number;
            2)    Original Inventory Report Form Number;
            3)    Premanufacture Notice Number;
            4)    Bona Fide Document Control Number; or
            5)    Test Market Exemption Application Number.

Use one of the above identifying numbers only if you cannot locate the CAS Registry
Number for a substance or you are uncertain whether the CAS Registry Number you
have located is correct.  The  CAS  Registry number is the preferred identifier for
chemical substances reported.
IUR 1994                                                             Page 17

                The substances on this sample form are listed as confidential
                only for purposes of illustration.
               IUR 1994
                                                                                            Page 18

-------
      (1)   EPA Accession Number.  (See line 2 of sample form.)  If the identity of
a chemical substance on the Inventory is confidential, the printed Inventory lists an
Accession Number for that substance and uses a generic name rather than a specific
identity. You may use an Accession Number as an identifying number oniyjf EPA has
communicated the appropriate Accession Number to you, e.g., following your report
for  the original  Inventory in 1978 or  1979,  or  following  commencement of
manufacture or import of a substance for which you filed a premanufacture notice.
If you find a generic chemical identity in the printed Inventory which you think belongs
to your substance, and  report using the Accession Number which pertains to that
substance, you may possibly report for the wrong substance. An Accession Number
may not be used for a  non-confidential chemical substance.  A typical Accession
Number would be "29735".

      (2)   Original Inventory Report Number. In 1978 and 1979, submissions for
the  Initial and Revised TSCA Chemical Substance Inventories were filed on one of four
forms,  "A", "B", "C", or  "E". You may use that original Inventory report form number
as an identifying number.  A typical Original Inventory Report Number  would be
"12345678".

      Since both "A" and "B" forms allowed reporting of several chemical substances
on a single form,  EPA needs to know the line number on the original "A" or "B" form
that the substance occupied.  If you use an original Inventory report number from an
"A" or "B" form (these form  numbers begin with "1" or "2")  you must therefore
include the original line number for that chemical substance, separated from the form
number by a slash. For example, if a chemical substance has been reported on line
number 3 of form 12345678,  report the identification number as "12345678/003";
(see line 9 on sample form). Add leading zeroes to make the line number three digits
long, e.g. # "001", "012", or  "123".  If you originally reported on  a "C" or "E" form
(form numbers beginning with "3" or "5"), include a slash and line number-of 001
(see lines 4 and 5 on sample form).

      If you submitted a correction to an original Inventory report, use the number of
the form on which you submitted the correction. Be sure to add  a line number (001),
as above.

      (3)   Premanufacture Notice Number.  (See line 6 of sample form.) If you filed
a Premanufacture Notice (PMN) for a substance which is now reportable under the
Inventory Update Rule and that PMN was assigned a PMN number, you may use that
as an identifying number. A typical PMN number would be "P-85-0243" or "P-83-
0001 A". The four digit block of numbers must be right justified with leading zeros
as needed.  The eighth space  is reserved for an optional alpha character suffix (A, B,
etc.) and should  be  used only if  one has been assigned  by EPA.  Please  be sure to
include the dashes in the correct locations.

      Please be aware  that a chemical substance which has a PMN number is not
automatically reportable under the Inventory Update Rule.  A PMN  substance is
IUR1994                                                              Page 19

-------
reportable under the IUR only if it is included on the Inventory. A PMN substance is
included on the Inventory only if a Notice of Commencement was received by EPA for
the substance.

      (4)    Bona Fide Request Control Number. (See line 3 of sample form, page 18)
If you filed a Bona Fide Intent to Manufacture or Import a chemical substance which
is  now  reportable  under  the  Inventory Update Rule (see  40  CFR §710.7(g)  or
§720.25(b)), you may use the document control number assigned to that submission
by EPA  as an identifying  number.  A typical Bona  Fide document control number
would be "528500287".

      The fact that you filed a Bona Fide for a substance does not necessarily mean
that the substance is on the Inventory and reportable; you must have independent
confirmation that the substance is on the Inventory (most likely in a communication
from EPA).

      (5)    Test Market Exemption Application  Number.  (See line 7 of sample form.)
If you filed a Test Market Exemption Application (TMEA) for a substance which is now
reportable under the Inventory Update Rule, the number assigned  by EPA to  that
application may be used as an identifying number.  A typical TMEA number would be
"T-85-0243"  or "T-83-0001A".   The four digit block of numbers must be  right
justified with leading zeros as needed. The eighth space is reserved for an optional
alpha character suffix (A, B, etc.) and should be used only if one has been assigned
by EPA. Please be sure to include the dashes in the correct locations. You should use
a TMEA number only if you know that the chemical substance is on the Inventory.

      Procedures for obtaining CAS Registry Numbers and Accession Numbers from
EPA when you previously reported the substance to the Agency.  If by one of the
methods discussed in Section II.A. (page 2), you were able to  determine that the
substances you manufacture are on the Inventory, you should already have identifying
numbers for them.   If you do not know any of the above identifying numbers for a
substance you are unlikely to be certain that the substance is on the Inventory. If this
is the case you should reread Section 11. A.  Following the procedures in that section
should enable you to find an identifying number.

      There may be some manufacturers or importers who reported for the Inventory
in 1978 or 1979 but no longer have the original report forms.  In this case you may
request an identifying number from EPA. Send  a letter to the following address:

                 OPPT Document Control Officer
                 U.S. Environmental Protection Agency
                 Office of Pollution Prevention and Toxics  (7407)
                 401 M Street, S.W.
                 Washington, DC  20460
                 Attn: Inventory Update Rule
 IUR 1994                                                            Page 20

-------
      The letter must include the specific identity of the chemical substance, must
be signed by an officer of the company, and must designate a technical contact
(include name, title, address, and telephone number). The structure of the substance,
if available, should also be provided. Note that this procedure can be used only when
you have previously reported the substance to the Agency; if you need EPA to tell you
whether the substance is on the Inventory you must follow the procedures in Section
M.A.2. (page 3).

      Information on this letter may itself be claimed as confidential by circling or
bracketing the text to be protected and marking the page "CONFIDENTIAL."  Failure
to so mark this information may result in EPA making the information available to the
public without further notice to you.

      EPA will release information in response to these letters only to the company
which originally submitted the information. If company ownership has changed or the
technical contact authorized to receive confidential information has changed since you
reported  the substance to EPA during  1978 -  1980, you must include a notarized
letter by an officer of the current surviving chemical company certifying to the change
and designating the new technical contact.

      EPA will send to the technical contact a CAS Registry Number (if the substance
is  listed  as non-confidential on  the Inventory)  or an  Accession  Number (if the
substance is confidential).

      EPA will release CAS Registry Numbers or Accession Numbers in response to
these  letters only for substances which are reportable under the Inventory Update
Rule.  Your letter must be received by  November  12, 1994; otherwise the Agency
cannot guarantee a response in time for you to meet your reporting obligations.

      d.     Specific Chemical Name (block H). Enter the specific chemical identity
of the chemical substance you are reporting. Chemical Abstracts Index or Preferred
Names should be used if available.  For non-confidential substances, these names can
IUR1994                                                              Page 21

-------
be found in either the printed or the computer-readable version of the Public Inventory.
If such names are not available, you must use nomenclature which  completely and
accurately describes the chemical substance.

      If the chemical identity will not fit on one line, you should truncate the name
at the end of the line with the use of an ellipsis (...) indicating an omission of letters
or words.  Each line should represent one chemical. (See line 4  of sample form, page
18)  Do not continue the chemical identity to the next line.

      Trade names may not be used except where a trade name describes a reactant
which  is part of the identity of  a chemical substance you are reporting and your
supplier will not disclose to you  the specific identity of the trade  name reactant.
Report all  such chemical substances on a separate  form, entering the  specific
identities of reactants where you know them and the trade names where you do not.
You must also submit along with Form U a letter certifying that your  supplier will not
disclose to you the specific identity of the trade name reactant and identifying the
supplier of each trade name reactant reported.

      Information in this letter may be claimed as confidential by circling or bracketing
the text to be protected and marking the page, "CONFIDENTIAL."  Failure to so mark
this information may result in EPA making the information available to the  public
without further notice to you.

      If you are an importer whose foreign supplier will not reveal to  you  the identity
of the substance you are reporting, follow the procedures in subsection H. (page 25).

      If you are claiming the chemical identity as confidential, check the Chemical CBI
box in block G.

      e.    Activity:   Manufacture or Import (block D).  If you manufacture  the
substance, enter "M" in the Activity box; enter "I" if you import  the substance.  If you
both manufacture and import the substance at the same site, use two lines to report,
one for each activity.  Check the CBI box if you wish to claim  the nature of the
activity (i.e., manufacture vs. importation) as confidential for the substance.  Claiming
activity as CBI does not protect the link between your company and the substance;
that will not be protected unless you check the CBI box next to Company Name.

      f.     Site Limited  (block E). If you manufacture the chemical substance at the
plant site identified and  do not  distribute the chemical substance  or any mixture
containing that substance outside the plant site for commercial purposes, enter  "X"
in the space next to the CBI box.  Otherwise leave the space  blank.  (Note:  an
imported chemical substance cannot be reported as site-limited.) If you wish to claim
this information as confidential for the substance, check the CBI box. You may claim
the fact that a substance is not site limited as confidential, if appropriate.
 IUR 1994                                                              Page 22

-------
      Q.    Production Volume (block R. Enter your annual manufacture volume or
importing volume, in pounds, for the fiscal year preceding the reporting period. If you
both manufacture and import a particular substance, report the  manufacture and
import volumes separately, on two lines.  The quantity should be reported to at least
two significant figures, and should be accurate to the extent known or reasonably
ascertainable by you (if the figure reported is within ±10% of the  actual value, it is
acceptable for purposes of the rule). Production volumes must be reported in numeric
format ("2 million" or "Ex10" are not acceptable): Abbreviations such as M or K are
also not acceptable. (Volumes reported in other than numeric format cannot be read
by the Agency's automated  equipment.)  If you wish to claim this information as
confidential for this substance, check the CBI box.

      h.    Plant site and Chemical CB)  Claims (block G).

      (1)   Plant site CBI claim. If you wish to claim the site of manufacture/import
as confidential, check the "Plant CBI"  box.  Note that you may claim this connection
as CBI for some chemical substances on the form while not making that claim for
others.

      (2)   Chemical identity CBI claim.  The identity of a substance which is listed
as confidential on the TSCA Inventory may be claimed as confidential by checking this
box. EPA wBI not honor a chemical identity CBI claim for a substance which is listed
on the non-confidential Inventory.  Note that checking this box does not protect the
link between your company and the substance; it only asserts a  CBI claim for the
specific identity of the substance.  If you wish to claim company identity  as CBI,
check the CBI box next to Company Name on the upper portion of the form.

D,    Reporting by diskette.

      1,    General.  In 1986 submitters were  offered the option of submitting
reports on computer tape.  For the 1990 collection, the option was expanded to
include diskettes. In this 1994 reporting period magnetic media submissions are again
encouraged; however, only diskettes will be accepted.

      2.    Copies of Form U required.   All diskettes must be accompanied by a
separate copy of Form U for each plant site reported. On the written form complete
only the technical contact and company information described in subsections IV.C.3.
and 4., on pages 15 and 16.  The remainder of the form should not be filled in. In its
place include a statement that the required information is being submitted on diskette,
plus diskette identifier information (this should match the information  on the label
affixed to the diskette).

       3.    Diskette formats and physical characteristics.

       See Appendix B for instructions on providing submissions on diskette.
IUR1994                                                               Page 23

-------
       4.    Information on individual chemical substances.

       See Appendix B and instructions for completing the Chemical Substance Block
in Section C.r above.

E.      Sending forms and diskettes to EPA.

       Send the original  form,  along  with  any accompanying diskettes, to the
following address:

                   OPPT Document Control Officer
                   U.S. Environmental Protection Agency
                   Office of Pollution Prevention and Toxics (7407)
                   401 M Street, S.W.
                   Washington, DC 20460
                   Attn: Inventory Update Rule

F.      Correcting errors in submissions for the original Inventory.

       In reporting under the Inventory Update Rule you may find that an error was
made when you reported for the original Inventory in 1978 or 1979.  If that error falls
into one of the following categories:

       1)    the chemical identity originally reported was incomplete or inaccurate;

       2)    an  isolated intermediate  occurring  during  the  manufacture  of a
             substance  previously  reported  for  the Inventory  was  not then
             recognized; or

       3)    EPA informed your company of a reporting error and  requested a
             correction from you, to which you did not respond;

you should  file an Inventory Correction, following the procedures outlined in the
Federal Register notice of July 29, 1980 (45 FR 50544).  Be sure to reference the
original Inventory report form and line number (if appropriate) when  you file a
correction.

       For  copies of the Federal Register notice or further assistance with  an
Inventory Correction, you may contact:

                   TSCA Hotline
                   U.S. Environmental Protection Agency
                   Office of Pollution Prevention and Toxics (7408)

                   Washington, DC 20460
                   Telephone: (202) 554-1404
 IUR1994                                                              Page 24

-------
       Inventory Correction requests should be submitted to EPA with your copies
of Form U.  Note that your Form U should report the chemical substance you are
actually manufacturing or importing.  The correction should be explained in a cover
letter by specifically referencing the number  of the correction form, the Form  U
number, and the Form U report line number.

       The act of correcting errors in submissions to the Original Inventory does not
grant to the person making the correction immunity from enforcement action for any
possible violations of the Original Inventory Reporting Rule.

G.     Recordkeepina requirements.

       Persons subject to the Inventory Update Rule are required to maintain records
that document the information contained in their submissions. These records must
be kept for four years after the effective date of the applicable reporting period. As
long as the  records are maintained in  a manner consistent with normal business
practice, you may determine their exact format. Required records include those that
show the production volume, plant site, and site-limited status of each substance
reported.  If a substance is not reported because its site-specific annual production is
less than 10,000 pounds, only the site-specific production records for that substance
need to be kept.  Persons who qualify as exempt small manufacturers need to keep
records only for those chemical  substances which  they are  required to report;
however, in claiming an exemption they bear the burden of documenting that they
qualify for the exemption.

H.     Special instructions for importers and foreign suppliers.

       This section applies to importers who do not know  the specific chemical
identity of a substance because the foreign supplier chooses to keep it confidential.
If you are such an importer, you are still  responsible for ensuring that the information
is  submitted  to EPA.  You may accomplish  this by  having your foreign supplier
complete some of the information on Form U,  as follows:

       1)     Include a cover letter with your submission, stating the following: "The
              identifying numbers and specific chemical identities for the substances
              on this form and the technical contact will  be submitted by our foreign
              supplier."

       2)     Use a separate Form U for each foreign supplier who does not inform
              you of the identity of the chemical substances you are importing.  Do
              not report by diskette. Do not use the same report form for substances
              whose specific identities you do know.

       3)     Make a photocopy of a blank Form U before entering any information
              on the form.
IUR1994                                                               Page 25

       4)     On  the  original  copy, sign the certification statement,  enter the
             technical contact, and complete blocks D, E, F and G for each chemical
             substance.  In block B, instead of entering the identifying number, enter
             the trade name or other designation by which you know each chemical
             substance.  Leave column C blank. Check the "Chemical CBI" box in
             block H only if  you wish  to claim the identities of the  chemicals
             identified  on  the  form  as  confidential  (you  must  answer the
             substantiation questions described in subsection  B.,  page 13).  Your
             foreign supplier is responsible for his own CBI claim. Send this copy to
             EPA.

       5)     On  the  photocopy of the blank form,  enter  only the  plant site
             information. Send  this copy to your foreign supplier.

       6)     The  foreign  supplier  should   enter  technical contact-company
             information on  his copy  (the technical contact  here should be the
             foreign supplier), complete  blocks B and C and enter the appropriate
             specific  chemical identities  in block H.  Make sure that your  supplier
             understands which chemical identities belong with each line number on
             Form U. If the foreign supplier wishes to claim the chemical identities
             as confidential, the supplier should  check the  "Confidential" box  in
             block G and submit  a substantiation as described in subsection B.,
             above.  The supplier should include with Form U a letter stating that
             this information  is  being submitted by a foreign supplier on behalf  of
             the  importer, who should be identified.  Information in the  letter may
             be claimed as confidential  by circling  or bracketing the text to be
             protected and marking the page, "CONFIDENTIAL." Failure to  so mark
             this information may result in EPA making the information available to
             the  public without further notice to the  supplier.  The supplier should
             then send the form and letter to EPA.

       Note  that  it is  your  responsibility to ensure  that your  foreign  supplier
understands how to complete his copy of  Form U (including any relevant CBI claims)
and that the supplier sends the information to EPA by the end of the  reporting period.
If the supplier fails to  submit the information, your company may be  subject to an
enforcement action.

V.     OBTAINING COPIES OF DOCUMENTS CITED IN THESE INSTRUCTIONS

A.     Obtaining copies of TSCA regulations.

       Copies of TSCA regulations can be obtained by contacting:

                  TSCA Hotline
                  U.S. Environmental Protection Agency
                  Office of Pollution Prevention and Toxics  (7408)
                  401 M Street, S.W.
                  Washington, DC 20460
                  Telephone: (202) 554-1404

B.     Obtaining copies of the Public Inventory.

       1.     Obtaining copies of the printed edition of the Public Inventory.  Non-
confidential Inventory listing can be found in the TSCA Chemical Substance Inventory:
1985 Edition,  a complete version of the Public (non-confidential) Inventory current
as of July 1985, and in the TSCA Chemical Substance Inventory: 1990 Supplement.
a supplement to the  1985 edition current as of February  1, 1990.  This printed
version contains the CAS Registry  Number, Preferred CA  Index Name, molecular
formula, and if applicable, the substance definition and  appropriate EPA  flags
(including the "XU" flag for substances exempt from reporting under the Inventory
Update Rule) for  non-confidential substances.   For chemical substances whose
chemical identity has been claimed as confidential, generic chemical names and EPA
accession numbers are listed.  Copies may be purchased from:

                  Superintendent of Documents
                  Government Printing Office
                  Washington, D.C. 20402
                  Order Desk: (202) 783-3238

       The price for the 1985 edition is $161.00 in the U.S. and Canada, $201.25
elsewhere; the  price for the 1990 supplement is $15.00 in the U.S.,  and $18.75
outside the U.S. if ordering by mail use the above address. GPO will also take orders
by telephone; MasterCard and Visa are accepted. Refer to stock number 055-000-
00254-1  for the 1985 edition, and 055-000-00254-1 for the 1990  supplement.
Please allow 4-6 weeks for delivery  (longer outside the U.S.).

       2.     Obtaining the Public Inventory in computer-readable form. The Public
Inventory is  available in the form of computer tapes or PC  diskettes.  Both can be
obtained from the National Technical  Information Service  (1-800-553-NTIS).  The
computer tape version consists of two tapes. The first tape, the Inventory Preferred
Name File, is sorted by CAS Registry Number. It contains the CAS Registry Number,
Preferred CA Index Name, molecular formula, and if  applicable,  the  substance
definition and appropriate EPA flags (including the "XU" flag for substances exempt


IUR1994                                                             Page 27

-------
from reporting under the Inventory Update Rule) for non-confidential substances. The
second tape, the Inventory Synonym Name file, contains the same data elements as
the first tape but differs in two ways.  First, it is sorted by chemical name, not CAS
Registry Number. Second, in addition to the Preferred CA Index names, this file is
expanded by the inclusion of valid names (synonyms) as supplied to EPA by Inventory
submitters. In contrast to the printed version of the Public Inventory which includes
CAS derived synonyms, the synonyms listed on this tape are only those reported to
EPA by Inventory submitters.

       The PC diskette version is a set of diskettes containing the information on
both computer tapes merged together with duplicate information removed.  It is in
CAS Registry Number order.

       The tapes and diskettes only contain information on chemical substances
which have not had confidentiality claims made on the chemical identity. They do not
reference in any way chemicals on the TSCA Inventory claimed as  confidential.

        Ordering information for these products may be obtained by contacting:
                   National Technical Information Service
                   5285 Port Royal Road

                                 Appendix A

                       Chemical Substances Subject to
                    Proposed or Final TSCA Rules or Orders

Following is a list of CAS Registry Numbers (for non-confidential chemical substances)
or Accession Numbers (for confidential substances) of substances which are subject
to proposed or final rules or orders under TSCA sections 4, 5(a)(2), 5(b)(4), 5(e), 5(f),
6, and 7, as  of April 1994  (see sections 710.26 and 710.29 of the rule and pages 6
and 8 in these reporting instructions). All chemical substances appearing on this list
are subject to IUR reporting. The usual exclusions for polymers, inorganic substances,
microorganisms, or small businesses  do not apply for substances on this list.  The
exclusion for naturally occurring substances is still valid, as referenced on page 6 of
this instruction manual.   If after consulting  the  list you are uncertain  as to the
regulatory status of a chemical substance, contact EPA at the address given on page
29 of these reporting instructions.

                                 Appendix B

           Instructions for Submitting IUR Reports on Magnetic Media
      EPA is encouraging ail 1994 IUR submitters to file their IUR reports in an
electronically readable format. Magnetic media submissions are preferred because
handling and archiving are more efficient and there is less likelihood of transcription
error than with paper copies.

      These instructions are  furnished for two purposes:  to allow companies to
determine whether they are able to comply with the general instructions for magnetic
media  submissions,  and to  provide the responsible computer professionals the
technical specifications they need to actually prepare the IUR electronic reports.

GENERAL INSTRUCTIONS

      An electronic IUR submission is produced by a plant site or company mailing
to EPA two flat ASCII files which report the appropriate production information from
each plant site.   All such submissions must be  on diskette.   Instructions in this
appendix describe who can report by such files, how to prepare the reporting packet,
specifications  for the preparation of the files, and a detailed description of their
contents.  Finally, instructions for mailing the submission are included.

Minimal Magnetic Media Reporting  Restrictions in 1994

      In the 1986 reporting cycle, no form U's containing chemicals with claims for
confidentiality could be submitted via magnetic media; however, this restriction is no
longer valid.  Magnetic  Form U reports may include  chemicals with claims for
confidentiality; a report with a variety of confidentiality claims on one submission is
also acceptable.

      There is also no longer a minimum or maximum number of chemicals to qualify
for electronic reporting; any number is acceptable. However, there is a maximum of
999 chemicals from one plant site.

      There are only two magnetic media restrictions remaining:

      1)    Importers who are unaware of the chemical identity of the substance
            which they are importing must report via hard copy; no magnetic media
            reporting is permitted. In this  case, the foreign supplier must have a
            hard copy of the Form U to provide the identity information to the EPA.

      2)    Any chemical with production volume exceeding 999,999,999,999 Ibs.
            must be reported on hard copy.
IUR 1994                                                                 B'1

-------
      No magnetic tapes will be accepted in this reporting cycle.  Only diskettes can
be processed in 1994.

Hard CODV Form Still Required

      Persons who file via magnetic media are still required to fill in the top portion
of the hard  copy Form  U report with  the certification statement and signature,
technical contact and company name, and plant site information in accordance with
subsection  IV.D.2.  (page 23) of the  instruction manual.   Any accompanying
information,  e.g., substantiation claim for CBI claims on chemical ID or Form C's for
Inventory corrections, would also be attached as hard copy pages. Only the chemical
substance identity/activity/production volume/confidentiality  information  can  be
furnished on the magnetic media.

      Note also that no  corrections for  any previously submitted reporting may be
made on magnetic media, for 1994 or any earlier reporting cycle. Corrections must
always be provided to EPA as hard copy.
TECHNICAL INFORMATION

Types of Acceptable Media

      In this cycle,  magnetic tapes  will  not  be accepted.   Only  ASCII diskette
submissions from IBM and compatible personal computers are permissible.  The
person preparing the submission should check file contents via the TYPE command
in DOS to ensure that the files are in ASCII format.

DISKETTE SUBMISSION TECHNICAL SPECIFICATIONS:

      DOS formatted:  2.3 or higher
      Double Density or High Density
      3.5" or 5.25" diskette dimensions
      ASCII text only (no word processing, data bases, or spread sheet files in native
            format)

One Form U Number per Site

      The Form U number on the top right of the form uniquely identifies the plant
site.  For  1994 reporting, the EPA will assign Form  U numbers starting from
61100000.  Numbers lower than 61100000 are unacceptable for 1994 reports.

      Each plant site must use a  different Form U number.  All plant sites must
submit a minimum of one hard copy Form U with the top portion filled out.  Every line
IUR1994                                                                B-2

-------
of the electronic file(s) will contain the Form U number which corresponds to the top
of the Form U filled out for that site.

      A single Form U  will  generally suffice for any single plant site if magnetic
reporting is anticipated for every substance. This differs from hard copy reporting,
where only ten chemicals are reportable per form.  There is an upper limit of 999
chemicals from one site, corresponding to one Form U number, if  a diskette is used
to convey the chemical information.  For example, plant site A could report on 135
chemicals using one Form U number and filling out  only the top portion of only one
Form U.  In the unlikely event that more than 999 chemicals are reportable from one
plant site, a second Form U will be required.

Data File Formats

      For each plant site, two ASCII data files will be prepared. The first data file is
a chemical name file (N is the record type and the first character in each line).  The
second data file is a submitter production  file (D is the record type and the  first
character in each line).  These files together will correspond to  the chemical identifi-
cation/activity/confidentiality block of the Form U (Blocks A. through H.).

      The chemical name file and the submitter production file must be submitted as
two separate files, rather than as alternating records in one consolidated file.

      The file format layouts for reporting are in Exhibits B-1  and B-2.  There should
be no deviations from these file formats.  Use the designated constants and do not
use any delimiters.  Where blanks or spaces are acceptable, be sure to maintain the
specified column positions by spacing over to the desired starting  point.

      Samples of valid electronic reporting are provided in Exhibit B-3.  The first field
in each file consists of the record type, either D or N, followed by a two digit number
denoting the number of record occurrences for the substance (always "00" for the D
file, see N file layout for more information on this number in the N file). Next is the
Form U number for the site, followed by a "line" number. The line numbers start with
'001' and each substance is assigned a sequential line number by the submitter.  For
example, in a valid submitter production file  the first six lines might begin with these
characters in the first fourteen columns:

D0061100012001...
D0061100012002...
D0061100012003...
D0061100012004.. .
D0061100012005.. .
D0061100012006...

-------
      There can be up to 999 lines, e.g., chemicals, reported per one plant site using
one Form U number.

      Submitters should not mix reporting from several sites in one file.  Each site
should submit two ASCII files, one for chemical names and one for submitter
production data. Both of the files will start with identical digits in the columns 4-14.
Both of the files will have the same number of lines (except where chemical names
are very long.  See below for additional details on handling long names).

      Companies may, however, submit the pairs of plant site files from multiple plant
sites on one diskette, e.g., Company A might submit a single diskette with twenty
four  files,  which  consist of  twelve chemical name files  and twelve submitter
production files, corresponding to twelve plant sites.

File Naming Conventions

      Submitters  should name diskette files using the  Form U  number, e.g. for
Company  A's plant site in Hometown,  KY, the chemical name  file might  be
61100012.NAM and the submitter production file might be 61100012.SUB. Use of
this convention will provide consistency.

Chemical Name File Instructions (File N)

      There is only one record format in this file.  No blanks or spaces, other than
those in the chemical name or at the end of the chemical name, will be included.

      Each record begins with the upper case "N" character in column 1  (field #1  =
Record Type).

      The sequence number in columns 2  3 (field # 2 = Sequence  Number) is
always right justified and zero filled, e.g. 01, 02. For names shorter than 135 bytes,
the sequence  number  will  always be  "01"  and the Form  U and line  number
combination (fields # 3 and 4) will occur only once per file.

      If the chemical name (field # 5 = Chemical Name) is longer than 135 bytes, the
sequence number in columns 2-3 will reflect the multiple occurrence, as follows.  In
this case, the Form U and line number combination (fields # 3 - 4, or cols. 4-14) may
occur more than  once per file.

Example of a long chemical name record for Form U  61100012, line 005:

      First segment of the chemical name will  start with
NpJ.61100012005Methyl...   (sequence number of "01")

      Second segment of the chemical name for the  same substance will begin with
N0261100012005benzyl...  (sequence  number of "02")

      The line number in columns 12   14 (field #4  = Line Number) is always right
justified and zero filled,  e.g., "005".

Submitter Production File Instructions (File D)

      There is only one record format in this file. Each record begins with an upper
case "D" in  column  1  (Field #1  = Record Type), followed by the constant "00" in
columns  2  3 (Field #2  = Sequence Number).  Fields #1 through #4  ("DOO" or
Record type/Sequence number, Form U number, Form U 'line') are mandatory on each
line. The same Form U number (Field #3) and Line number (Field #4) combination can
occur only once per file.

      In reporting a chemical identifier in fields #5 through #11 or columns 15 - 68,
several options are available.  The submitter is expected to fill out only one chemical
identifier  (either field #5, #6, #7 and #8, #9, #10 or #11) and leave the remaining
fields blank.  See Section III.C.5.b. and c. (page 16) of the manual for guidance.

      Other  than within the chemical identifier area (fields #5-11, columns 15 - 68),
blanks or spaces are acceptable  only in the column for Site Limited (field #14; col.
71).  All  numeric values  must  be zero filled and right justified.   All alphabetic
characters must be upper case.  Entries in fields #12, #13 and  #15 through #19,
columns 69  - 70 and 72 - 87, are mandatory; no blanks or spaces are allowed.

MAILING INSTRUCTIONS

      If the diskette contains CBI, it should be physically labeled indicating that it
"Contains TSCA CBI".  It should be  identified with the company name and, if
appropriate, the plant site.  Read-only tab protection should be applied. If more than
one diskette is submitted by a company, the labels should also indicate the number
and the total number, e.g., disk 1 of 2, disk 2 of 2.

      Diskettes should be placed in a  durable mailing container, as damaged diskettes
will be returned to the submitter without further attempt by EPA to recover data.  It
is advisable to send a backup diskette, in case of damage to the primary diskette.

      All feasible precautions in mailing magnetic media containing CBI  should be
adopted by the submitter  for its protection, such as double wrapped envelopes,
registered mail, etc., just as one would apply to the hard copy  submission.  The
signed Form U should also  be included in the same mailing packet.

      Cover letters accompanying any magnetic media submission should refer to the
CBI status of the submissions, and should list plant site, Form U numbers and the
corresponding file  names.   Number of records (chemicals)  per  file may  also  be
specified.  A technical contact name for data processing matters, if different from the
contact on the form, should be identified in the cover letter.

      Questions about  the magnetic  media submission instructions should  be
addressed to:
