                       Subpart--General Provisions



Sec. 716.1  Scope and compliance.

    (a) This subpart sets forth requirements for the submission of lists 
and copies of health and safety studies on chemical substances and 
mixtures selected for priority consideration for testing rules under 
section 4(a) of the Toxic Substances Control Act (TSCA) and on other 
chemical substances and mixtures for which EPA requires health and 
safety information in fulfilling the purposes of TSCA.
    (b) Section 15(3) of TSCA makes it unlawful for any person to fail 
or refuse to submit information required under this subpart. Section 16 
provides that a violation of section 15 renders a person liable to the 
United States for a civil penalty and possible criminal prosecution. 
Under section 17, the district courts of the United States have 
jurisdiction to restrain any violation of section 15.



Sec. 716.3  Definitions.

    The definitions in section 3 of TSCA apply to this subpart. In 
addition, the following definitions are provided for the purposes of 
this subpart:
    Byproduct means a chemical substance produced without a separate 
commercial intent during the manufacture, processing, use, or disposal 
of another chemical substance(s) or mixture(s).

[[Page 53]]

    Co-product means a chemical substance produced for a commercial 
purpose during the manufacture, processing, use, or disposal of another 
chemical substance(s) or mixture(s).
    Copy of study means the written presentation of the purpose and 
methodology of a study and its results.
    EPA means the United States Environmental Protection Agency.
    Health and safety study or study means any study of any effect of a 
chemical substance or mixture on health or the environment or on both, 
including underlying data and epidemiological studies, studies of 
occupational exposure to a chemical substance or mixture, toxicological, 
clinical, and ecological or other studies of a chemical substance or 
mixture, and any test performed under TSCA.
    (1) It is intended that the term health and safety study be 
interpreted broadly. Not only is information which arises as a result of 
a formal, disciplined study included, but other information relating to 
the effects of a chemical substance or mixture on health or the 
environment is also included. Any data that bear on the effects of a 
chemical substance on health or the environment would be included. 
Chemical identity is part of, or underlying data to, a health and safety 
study.
    (2) Examples are:
    (i) Long- and short-term tests of mutagenicity, carcinogenicity, or 
teratogenicity; data on behavioral disorders; dermatoxicity; 
pharmacological effects; mammalian absorption, distribution, metabolism, 
and excretion; cumulative, additive, and synergistic effects; and acute, 
subchronic, and chronic effects.
    (ii) Tests for ecological or other environmental effects on 
invertebrates, fish, or other animals, and plants, including: Acute 
toxicity tests, chronic toxicity tests, critical life-stage tests, 
behavioral tests, algal growth tests, seed germination tests, plant 
growth or damage tests, microbial function tests, bioconcentration or 
bioaccumulation tests, and model ecosystem (microcosm) studies.
    (iii) Assessments of human and environmental exposure, including 
workplace exposure, and impacts of a particular chemical substance or 
mixture on the environment, including surveys, tests, and studies of: 
Biological, photochemical, and chemical degradation; structure/activity 
relationships; air, water, and soil transport; biomagnification and 
bioconcentration; and chemical and physical properties, e.g., boiling 
point, vapor pressure, evaporation rates from soil and water, octanol/
water partition coefficient, and water solubility.
    (iv) Monitoring data, when they have been aggregated and analyzed to 
measure the exposure of humans or the environment to a chemical 
substance or mixture.
    Import means to import for commercial purposes.
    Import for commercial purposes means to import with the purpose of 
obtaining an immediate or eventual commercial advantage for the 
importer, and includes the importation of any amount of a chemical 
substance or mixture. If a chemical substance or mixture containing 
impurities is imported for commercial purposes, then those impurities 
are also imported for commercial purposes.
    Importer means any person who imports a chemical substance, 
including a chemical substance as a part of a mixture or article, into 
the customs territory of the United States and includes the person 
primarily liable for the payment of any duties on the merchandise or an 
authorized agent acting on his behalf (as defined in 19 CFR 1.11). 
Importer also includes, as appropriate:
    (1) The consignee.
    (2) The importer of record.
    (3) The actual owner, if an actual owner's declaration and 
superseding bond has been filed in accordance with 19 CFR 141.20.
    (4) The transferee, if the right to draw merchandise in a bonded 
warehouse has been transferred in accordance with Subpart C of 19 CFR 
Part 144. For the purpose of this definition, the customs territory of 
the United States consists of the 50 States, Puerto Rico, and the 
District of Columbia.
    Impurity means a chemical substance which is unintentionally present 
with another chemical substance.
    Listed mixture means any mixture listed in Sec. 716.120.

[[Page 54]]

    Manufacture means to manufacture for commercial purposes.
    Manufacture for commercial purposes means: (1) To produce, with the 
purpose of obtaining an immediate or eventual commercial advantage for 
the manufacturer, and includes among other things such ``manufacture'' 
of any amount of a chemical substance or mixture:
    (i) For commercial distribution, including for test marketing.
    (ii) For use by the manufacturer, including use for product research 
and development, or as an intermediate.
    (2) Manufacture for commercial purposes also applies to substances 
that are produced coincidentally during the manufacture, processing, 
use, or disposal of another substance or mixture, including byproducts 
and impurities. Such byproducts and impurities may, or may not, in 
themselves have commercial value. They are nonetheless produced for the 
purpose of obtaining a commercial advantage since they are part of the 
manufacture of a chemical product for a commercial purpose.
    Manufacturer means a person who produces or manufactures a chemical 
substance. A person who extracts a component chemical substance from a 
previously existing chemical substance or a complex combination of 
substances is a manufacturer of that component chemical substance.
    Person includes any individual, firm, company, corporation, joint-
venture, partnership, sole proprietorship, association, or any other 
business entity, any State or political subdivision thereof, any 
municipality, any interstate body, and any department, agency, or 
instrumentality of the Federal government.
    Process means to process for commercial purposes.
    Process for commercial purposes means the preparation of a chemical 
substance or mixture, after its manufacture, for distribution in 
commerce with the purpose of obtaining an immediate or eventual 
commercial advantage for the processor. Processing of any amount of a 
chemical substance or mixture is included. If a chemical substance or 
mixture containing impurities is processed for commercial purposes, then 
those impurities are also processed for commercial purposes.
    Propose to manufacture, import, or process means that a person has 
made a management decision to commit financial resources toward the 
manufacture, importation, or processing of a substance or mixture.
    Substance means chemical substance as defined at section 3(2)(A) of 
TSCA, 15 U.S.C. 2602(2)(A).
    TSCA means the Toxic Substances Control Act (15 U.S.C. 2601 et 
seq.).

Sec. 716.45  How to report on substances and mixtures.

    Section 716.120 lists substances and mixtures, in order by Chemical 
Abstract Service Registry Number and by alphabetical order. Studies of 
listed substances and listed mixtures shall be reported as follows:
    (a) When a substance is individually listed under Sec. 716.120(a), 
studies of the substance and studies of mixtures known to contain the 
substance must be reported as studies of that substance.
    (b) When two or more substances are listed as a mixture under 
Sec. 716.120(b), studies of the listed mixture and studies of any 
mixture known to contain the listed mixture must be reported as studies 
of the listed mixture.
    (c) Studies of the following preparations of a substance must be 
reported as studies of the substance itself, not

[[Page 58]]

as studies of mixtures known to contain the substance.
    (1) The substance in aqueous solution.
    (2) The substance containing a small amount of an additive, such as 
a stabilizer, emulsifier, or other chemical added for purposes of 
maintaining the integrity or physical form of the substance.
    (3) The substance at any grade of purity.



Sec. 716.50  Reporting physical and chemical properties.

    Studies of physical and chemical properties must be reported under 
this subpart if performed for the purpose of determining the 
environmental or biological fate of a substance, and only if they 
investigated one or more of the following properties:
    (a) Water solubility.
    (b) Adsorption/desorption on particulate surfaces, e.g., soil.
    (c) Vapor pressure.
    (d) Octanol/water partition coefficient.
    (e) Density/relative density (specific gravity).
    (f) Particle size distribution for insoluble solids.
    (g) Dissociation constant.
    (h) Degradation by photochemical mechanisms--aquatic and 
atmospheric.
    (i) Degradation by chemical mechanisms--hydrolytic, reductive, and 
oxidative.
    (j) Degradation by biological mechanisms--aerobic and anaerobic.



Sec. 716.55  Confidentiality claims.

    (a)(1) Section 14(b) of TSCA provides that EPA may not withhold from 
disclosure, on the grounds that they are confidential business 
information, health and safety studies of any substance or mixture that 
has been offered for commercial distribution (including for test 
marketing purposes and for use in research and development), any 
substance or mixture for which testinq is required under TSCA section 4, 
or any substance for which notice is required under TSCA section 5, 
except to the extent that disclosure of data from such studies would 
reveal--
    (i) Processes used in the manufacturing, importing, or processing of 
the substance or mixture, or
    (ii) The portion of a mixture comprised by any of the substances in 
the mixture.
    (2) Any respondent who wishes to assert a claim that part of a study 
should be withheld from disclosure because disclosure would reveal a 
confidential process or quantitative mixture composition should briefly 
state the basis of the claim, e.g., by saying ``reveals confidential 
mixture proportion data,'' and clearly identify the material subject to 
the claim.
    (3) Any respondent may assert a confidentiality claim for company 
name or address, financial statistics, and product codes used by a 
company. This information will not be subject to the disclosure 
requirements of section 14(b) of TSCA.
    (4) Information other than company name or address, financial 
statistics, and product codes used by a company, which is contained in a 
study, the disclosure of which would clearly be an unwarranted invasion 
of personal privacy (such as individual medical records), will be 
considered confidential by EPA as provided in Title 5, United States 
Code, section 552(b)(6).
    (b) To assert a claim of confidentiality for data contained in a 
submitted document, the respondent must submit two copies of the 
document:
    (1) One copy must be complete. In that copy, the respondent must 
indicate what data, if any, are claimed as confidential by bracketing or 
underlining the specific information. Each page containing data claimed 
as confidential must also contain a brief statement for the basis of the 
claim as well as a label such as ``confidential,'' ``proprietary,'' or 
``trade secret.''
    (2) The second copy must be complete, except that all information 
claimed as confidential in the first copy must be deleted. The second 
copy will be immediately subject to public disclosure.
    (3) Failure to furnish a second copy when information is claimed as 
confidential in the first copy will be considered a presumptive waiver 
of the claim of confidentiality. EPA will notify the respondent by 
certified mail

[[Page 59]]

that a finding of a presumptive waiver of the claim of confidentiality 
has been made. The respondent will be given 30 days from the date of his 
or her receipt of this notification to submit the required second copy. 
If the respondent fails to submit the second copy within the 30 days, 
EPA will place the first copy in the public file.
    (c) If no claim of confidentiality accompanies a document at the 
time it is submitted to EPA, the document will be placed in an open file 
available to the public without further notice to the respondent.



Sec. 716.60  Reporting schedule.

    (a) General requirements. Except as provided in paragraphs (b) and 
(c) of this section, submissions under Secs. 716.30 and 716.35 must be 
postmarked on or before 60 days after the effective date of the listing 
of a substance or listed mixture in Sec. 716.120 or within 60 days of

Sec. 716.65   Reporting period.

    (a) The reporting period on a substance or listed mixture will 
terminate no later than: 10 years after the effective date on which a 
substance or listed mixture is added to Sec. 716.120; or on the removal 
of the substance or listed mixture from Sec. 716.120. The Assistant 
Administrator for Prevention, Pesticides and Toxic Substances has the 
authority to remove a substance or listed mixture from Sec. 716.120.
    (b) The EPA Office of Pollution Prevention and Toxics (OPPT) will 
conduct a biennial review of all of the chemical substances and mixtures 
listed in Sec. 716.120, and request from other EPA offices and certain 
Federal agencies, all reasonable justifications for retaining each 
substance or mixture on, or removing each substance or mixture from, the 
Sec. 716.120 list. Following each such review, the Assistant 
Administrator for Prevention, Pesticides and Toxic Substances will 
remove any substance or mixture for which no reasonable justification 
has been received to retain such substance or mixture on the 
Sec. 716.120 list. The Assistant Administrator may remove a substance or 
listed mixture from Sec. 716.120 by publishing, without notice and 
comment, a final rule to that effect in the Federal Register. The rule 
shall not be effective any earlier than 90 days after its publication. 
Persons who believe that EPA should not remove a substance or listed 
mixture from Sec. 716.120 may notify EPA and provide reasons for 
retaining the substance or listed mixture. If a reasonable justification 
for retaining a substance or listed mixture on the Sec. 716.120 list is 
received, EPA will withdraw the substance from the final rule before its 
effective date.
    (c) Notwithstanding the termination by the sunset provision in (a) 
above, removing a substance or listed mixture from Sec. 716.120 also 
terminates the applicability of Sec. 716.5(a)(3) to that substance or 
listed mixture so that persons first proposing to manufacture, import, 
or process the substance or listed mixture after the effective date of 
the removal have no reporting obligation under section 8(d) with respect 
to that substance or listed mixture. The removal also terminates the 
continuing obligation under Sec. 716.35(a)(2) of

[[Page 60]]

persons previously subject to the rule under Sec. 716.5(a)(2) or (3) to 
notify EPA of any initiation of studies on the removed substance or 
listed mixture that occur after the effective date of the removal. Only 
one reporting requirement would remain in effect. Persons who have been 
subject to the rule under Sec. 716.5(a)(2) or (3) and who have submitted 
to EPA lists of ongoing or initiated studies under Sec. 716.35(a)(1) or 
(2) must notify EPA of the completed study and submit the study 
regardless of the study's completion date.



                  Subpart B--Specific Chemical Listings



Sec. 716.105   Additions of substances and mixtures to which this subpart applies.

    The requirements of this subpart will be extended periodically to 
cover additional substances and mixtures. Two procedures will be used to 
add substances and mixtures.
    (a) Except as provided in paragraph (b) of this section, substances 
and mixtures will be added to Sec. 716.120 after publication in the 
Federal Register of a notice of proposed amendment to this subpart. 
There will be at least a 30-day public comment period on the notice. 
After consideration of the comments, EPA will amend Sec. 716.120 by 
final rule to add the substances and listed mixtures.
    (b) Except as provided in paragraph (c) of this section, chemical 
substances, mixtures, and categories of chemical substances that have 
been added to the TSCA section 4(e) Priority List by the Interagency 
Testing Committee, established under section 4 of TSCA, will be added to 
Sec. 716.120 but only to the extent that the total number of designated 
and recommended substances, mixtures and categories of chemical 
substances has not exceeded 50 in any 1 year. The addition of such 
chemical substances, mixtures, and categories of chemical substances to 
Sec. 716.120 will be effective 30 days after publication of a notice to 
that effect in the Federal Register.
    (c) Prior to the effective date of an amendment under paragraph (b) 
of this section, the Assistant Administrator for Prevention, Pesticides 
and Toxic Substances may for good cause withdraw a chemical substance, 
mixture, or category of chemical substances from Sec. 716.120. Any 
information submitted showing why a chemical substance, mixture, or 
category of chemical substances should be withdrawn from the amendment 
must be received by EPA within 14 days after the date of publication of 
the notice under paragraph (b) of this section. If a chemical substance, 
mixture, or category of chemical substances is withdrawn, a Federal 
Register notice announcing this decision will be published no later than 
the effective date of the amendment under paragraph (b) of this section. 
Persons who wish to submit information that shows why a chemical should 
be withdrawn must address their comments, in writing to the Document 
Control Office (7407), Office of Pollution Prevention and Toxics, U.S. 
Environmental Protection Agency, Room G-099, 401 M St., SW., Washington, 
DC., 20460, ATTN: 8(d) Auto-ITC.

Sec. 716.120  Substances and listed mixtures to which this subpart applies.

    Substances listed in this section appear in order by Chemical 
Abstract Service Registry Number. Chemical mixtures and categories are 
listed separately and by alphabetical order. Chemical substances listed 
within a category are provided only as examples of the category, and are 
not included on the list of substances. When a chemical substance in the 
substance or category list had been listed previously by a trivial (or 
common) name, it appears first, followed by the Chemical Abstract 
Service (CAS) name appearing in the TSCA Chemical Substance Inventory.
    (a) List of substances. The following chemical substances are 
subject to all the provisions of part 716. Manufacturers, importers, and 
processors of a listed substance are subject to the reporting 
requirements of subpart A for that substance.
