Subpart A—General Provisions and Applicability
top

§ 725.1 Scope and purpose.
top
(a) This part establishes all reporting requirements under section 5 of TSCA for manufacturers,
importers, and processors of microorganisms subject to TSCA jurisdiction for commercial purposes,
including research and development for commercial purposes. New microorganisms for which
manufacturers and importers are required to report under section 5(a)(1)(A) of TSCA are those that are
intergeneric. In addition, under section 5(a)(1)(B) of TSCA, manufacturers, importers, and processors
may be required to report for any microorganism that EPA determines by rule is being manufactured,
imported, or processed for a significant new use.
(b) Any manufacturer, importer, or processor required to report under section 5 of TSCA (see §725.100
for new microorganisms and §725.900 for significant new uses) must file a Microbial Commercial Activity
Notice (MCAN) with EPA, unless the activity is eligible for a specific exemption as described in this part.
The general procedures for filing MCANs are described in subpart D of this part. The exemptions from
the requirement to file a MCAN are for certain kinds of contained activities (see §§725.424 and
725.428), test marketing activities (see §725.300), and research and development activities described in
paragraph (c) of this section.
(c) Any manufacturer, importer, or processor required to file a MCAN for research and development
(R&D) activities may instead file a TSCA Experimental Release Application (TERA) for a specific test
(see §725.250). A TERA is not required for certain R&D activities; however a TERA exemption does not
extend beyond the research and development stage, to general commercial use of the microorganism,
for which compliance with MCAN requirements is required. The TERA exemptions are for R&D activities
subject to other Federal agencies or programs (see §725.232), certain kinds of contained R&D activities
(see §725.234), and R&D activities using certain listed microorganisms (see §725.238).
(d) New microorganisms will be added to the Inventory established under section 8 of TSCA once a
MCAN has been received, the MCAN review period has expired, and EPA receives a Notice of
Commencement (NOC) indicating that manufacture or importation has actually begun. New
microorganisms approved for use under a TERA will not be added to the Inventory until a MCAN has
been received, the MCAN review period has expired, and EPA has received an NOC.

§ 725.3 Definitions.
top
Definitions in section 3 of the Act (15 U.S.C. 2602), as well as definitions contained in §§704.3, 720.3,
and 721.3 of this chapter, apply to this part unless otherwise specified in this section. In addition, the
following definitions apply to this part:
Consolidated microbial commercial activity notice or consolidated MCAN means any MCAN submitted to
EPA that covers more than one microorganism (each being assigned a separate MCAN number by

Exemption request means any application submitted to EPA under subparts E, F, or G of this part.
General commercial use means use for commercial purposes other than research and development.
Genome means the sum total of chromosomal and extrachromosomal genetic material of an isolate and
any descendants derived under pure culture conditions from that isolate.
Health and safety study of a microorganism or health and safety study means any study of any effect of
a microorganism or microbial mixture on health or the environment or on both, including underlying data
and epidemiological studies, studies of occupational exposure to a microorganism or microbial mixture,
toxicological, clinical, and ecological, or other studies of a microorganism or microbial mixture, and any
test performed under the Act. Microorganism identity is always part of a health and safety study of a
microorganism.
(1) It is intended that the term “health and safety study of a microorganism” 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 microorganism or microbial mixture on health or the environment is also
included. Any data that bear on the effects of a microorganism on health or the environment would be
included.
(2) Examples include:
(i) 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.
(ii) Long- and short-term tests of mutagenicity, carcinogenicity, or teratogenicity; dermatoxicity;
cumulative, additive, and synergistic effects; and acute, subchronic, and chronic effects.
(iii) Assessments of human and environmental exposure, including workplace exposure, and impacts of
a particular microorganism or microbial mixture on the environment, including surveys, tests, and studies
of: Survival and transport in air, water, and soil; ability to exchange genetic material with other
microorganisms, ability to colonize human or animal guts, and ability to colonize plants.
(iv) Monitoring data, when they have been aggregated and analyzed to measure the exposure of
humans or the environment to a microorganism.
(v) Any assessments of risk to health and the environment resulting from the manufacture, processing,
distribution in commerce, use, or disposal of the microorganism.
Inactivation means that living microorganisms are rendered nonviable.
Institutional Biosafety Committee means the committees described in the NIH Guidelines in section
IV.B.2.
Intergeneric microorganism means a microorganism that is formed by the deliberate combination of
genetic material originally isolated from organisms of different taxonomic genera.
(1) The term “intergeneric microorganism” includes a microorganism which contains a mobile genetic
element which was first identified in a microorganism in a genus different from the recipient
microorganism.
(2) The term “intergeneric microorganism” does not include a microorganism which contains introduced

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

Electronic Code of Federal Regulations:

genetic material consisting of only well-characterized, non-coding regulatory regions from another
genus.
Introduced genetic material means genetic material that is added to, and remains as a component of,
the genome of the recipient.
Manufacture, import, or process for commercial purposes means:
(1) To import, produce, manufacture, or process with the purpose of obtaining an immediate or eventual
commercial advantage for the manufacturer, importer, or processor, and includes, among other things,
“manufacture” or “processing” of any amount of a microorganism or microbial 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) The term also applies to substances that are produced coincidentally during the manufacture,
processing, use, or disposal of another microorganism or microbial mixture, including byproducts that
are separated from that other microorganism or microbial mixture and impurities that remain in that
microorganism or microbial mixture. Byproducts and impurities without separate commercial value are
nonetheless produced for the purpose of obtaining a commercial advantage, since they are part of the
manufacture or processing of a microorganism for commercial purposes.
Microbial commercial activity notice or MCAN means a notice for microorganisms submitted to EPA
pursuant to section 5(a)(1) of the Act in accordance with subpart D of this part.
Microbial mixture means any combination of microorganisms or microorganisms and other chemical
substances, if the combination does not occur in nature and is not an article.
Microorganism means an organism classified, using the 5-kingdom classification system of Whittacker,
in the kingdoms Monera (or Procaryotae), Protista, Fungi, and the Chlorophyta and the Rhodophyta of
the Plantae, and a virus or virus-like particle.
Mobile genetic element or MGE means an element of genetic material that has the ability to move
genetic material within and between organisms. “Mobile genetic elements” include all plasmids, viruses,
transposons, insertion sequences, and other classes of elements with these general properties.
New microorganism means a microorganism not included on the Inventory.
NIH Guidelines means the National Institutes of Health (NIH) “Guidelines for Research Involving
Recombinant DNA Molecules” (July 5, 1994).
Non-coding regulatory region means a segment of introduced genetic material for which:
(1) The regulatory region and any inserted flanking nucleotides do not code for protein, peptide, or
functional ribonucleic acid molecules.
(2) The regulatory region solely controls the activity of other regions that code for protein or peptide
molecules or act as recognition sites for the initiation of nucleic acid or protein synthesis.
Small quantities solely for research and development (or “small quantities solely for purposes of
scientific experimentation or analysis or research on, or analysis of, such substance or another
substance, including such research or analysis for development of a product”) means quantities of a
microorganism manufactured, imported, or processed or proposed to be manufactured, imported, or
processed solely for research and development that meet the requirements of §725.234.
Structure means a building or vessel which effectively surrounds and encloses the microorganism and
includes features designed to restrict the microorganism from leaving.
Submission means any MCAN or exemption request submitted to EPA under this part.

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

Electronic Code of Federal Regulations:

Technically qualified individual means a person or persons:
(1) Who, because of education, training, or experience, or a combination of these factors, is capable of
understanding the health and environmental risks associated with the microorganism which is used
under his or her supervision,
(2) Who is responsible for enforcing appropriate methods of conducting scientific experimentation,
analysis, or microbiological research to minimize such risks, and
(3) Who is responsible for the safety assessments and clearances related to the procurement, storage,
use, and disposal of the microorganism as may be appropriate or required within the scope of
conducting a research and development activity.
TSCA Experimental Release Application or TERA means an exemption request for a research and
development activity, which is not eligible for a full exemption from reporting under §725.232, 725.234,
or 725.238, submitted to EPA in accordance with subpart E of this part.
Well-characterized for introduced genetic material means that the following have been determined:
(1) The function of all of the products expressed from the structural gene(s).
(2) The function of sequences that participate in the regulation of expression of the structural gene(s).
(3) The presence or absence of associated nucleotide sequences and their associated functions, where
associated nucleotide sequences are those sequences needed to move genetic material including
linkers, homopolymers, adaptors, transposons, insertion sequences, and restriction enzyme sites.

§ 725.8 Coverage of this part.
top
(a) Microorganisms subject to this part. Only microorganisms which are manufactured, imported, or
processed for commercial purposes, as defined in §725.3, are subject to the requirements of this part.
(b) Microorganisms automatically included on the Inventory. Microorganisms that are not intergeneric
are automatically included on the Inventory.
(c) Microorganisms not subject to this part. The following microorganisms are not subject to this part,
either because they are not subject to jurisdiction under the Act or are not subject to reporting under
section 5 of the Act.
(1) Any microorganism which would be excluded from the definition of “chemical substance” in section 3
of the Act and §720.3(e) of this chapter.
(2) Any microbial mixture as defined in §725.3. This exclusion applies only to a microbial mixture as a
whole and not to any microorganisms and other chemical substances which are part of the microbial
mixture.
(3) Any microorganism that is manufactured and processed solely for export if the following conditions
are met:
(i) The microorganism is labeled in accordance with section 12(a)(1)(B) of the Act, when the
microorganism is distributed in commerce.
(ii) The manufacturer and processor can document at the commencement of manufacturing or
processing that the person to whom the microorganism will be distributed intends to export it or process
it solely for export as defined in §721.3 of this chapter.

§ 725.12 Identification of microorganisms for Inventory and other listing purposes.

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

top
To identify and list microorganisms on the Inventory, both taxonomic designations and supplemental
information will be used. The supplemental information required in paragraph (b) of this section will be
used to specifically describe an individual microorganism on the Inventory. Submitters must provide the
supplemental information required by paragraph (b) of this section to the extent necessary to enable a
microorganism to be accurately and unambiguously identified on the Inventory.
(a) Taxonomic designation. The taxonomic designation of a microorganism must be provided for the
donor organism and the recipient microorganism to the level of strain, as appropriate. These
designations must be substantiated by a letter from a culture collection, literature references, or the
results of tests conducted for the purpose of taxonomic classification. Upon EPA's request to the
submitter, data supporting the taxonomic designation must be provided to EPA. The genetic history of
the recipient microorganism should be documented back to the isolate from which it was derived.
(b) Supplemental information. The supplemental information described in paragraphs (b)(1) and (b)(2) of
this section is required to the extent that it enables a microorganism to be accurately and unambiguously
identified.
(1) Phenotypic information. Phenotypic information means pertinent traits that result from the interaction
of a microorganism's genotype and the environment in which it is intended to be used and may include
intentionally added biochemical and physiological traits.
(2) Genotypic information. Genotypic information means the pertinent and distinguishing genotypic
characteristics of a microorganism, such as the identity of the introduced genetic material and the
methods used to construct the reported microorganism. This also may include information on the vector
construct, the cellular location, and the number of copies of the introduced genetic material.

§ 725.15 Determining applicability when microorganism identity or use is confidential
or uncertain.
top
(a) Consulting EPA. Persons intending to conduct activities involving microorganisms may determine
their obligations under this part by consulting the Inventory or the microorganisms and uses specified in
§725.239 or in subpart M of this part. This section establishes procedures for EPA to assist persons in
determining whether the microorganism or the use is listed on the Inventory, in §725.239 or in subpart M
of this part.
(1) Confidential identity or use. In some cases it may not be possible to directly determine if a specific
microorganism is listed, because portions of that entry may contain generic information to protect
confidential business information (CBI). If any portion of the microorganism's identity or use has been
claimed as CBI, that portion does not appear on the public version of the Inventory, in §725.239 or in
subpart M of this part. Instead, it is contained in a confidential version held in EPA's Confidential
Business Information Center (CBIC). The public versions contain generic information which masks the
confidential business information. A person who intends to conduct an activity involving a microorganism
or use whose entry is described with generic information will need to inquire of EPA whether the
unreported microorganism or use is on the confidential version.
(2) Uncertain microorganism identity. The current state of scientific knowledge leads to some
imprecision in describing a microorganism. As the state of knowledge increases, EPA will be developing
policies to determine whether one microorganism is equivalent to another. Persons intending to conduct
activities involving microorganisms may inquire of EPA whether the microorganisms they intend to
manufacture, import, or process are equivalent to specific microorganisms described on the Inventory, in
§725.239, or in subpart M of this part.
(b) Requirement of bona fide intent. (1) EPA will answer the inquiries described in paragraph (a) of this
section only if the Agency determines that the person has a bona fide intent to conduct the activity for
which reporting is required or for which any exemption may apply.
(2) To establish a bona fide intent to manufacture, import, or process a microorganism, the person who
intends to manufacture, import, or process the microorganism must submit the following information in
writing to the Office of Pollution Prevention and Toxics, Document Control Officer, 7407, 1200

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

Electronic Code of Federal Regulations:

Pennsylvania Ave., NW., Washington, DC 20460, ATTN: BIOTECH bona fide submission.
(i) Taxonomic designations and supplemental information required by §725.12.
(ii) A signed statement certifying that the submitter intends to manufacture, import, or process the
microorganism for commercial purposes.
(iii) A description of research and development activities conducted with the microorganism to date,
demonstration of the submitter's ability to produce or obtain the microorganism from a foreign
manufacturer, and the purpose for which the person will manufacture, import, or process the
microorganism.
(iv) An indication of whether a related microorganism was previously reviewed by EPA to the extent
known by the submitter.
(v) A specific description of the major intended application or use of the microorganism.
(c) If an importer or processor cannot provide all the information required by paragraph (b) of this
section, because it is claimed as confidential business information by its foreign manufacturer or
supplier, the foreign manufacturer or supplier may supply the information directly to EPA.
(d) EPA will review the information submitted by the manufacturer, importer, or processor under this
paragraph to determine whether that person has shown a bona fide intent to manufacture, import, or
process the microorganism. If necessary, EPA will compare this information to the information requested
for the confidential microorganism under §725.85(b)(3)(iii).
(e) In order for EPA to make a conclusive determination of the microorganism's status, the proposed
manufacturer, importer, or processor must show a bona fide intent to manufacture, import, or process
the microorganism and must provide sufficient information to establish identity unambiguously. After
sufficient information has been provided, EPA will inform the manufacturer, importer, or processor
whether the microorganism is subject to this part and if so, which sections of this part apply.
(f) If the microorganism is found on the confidential version of the Inventory, in §725.239 or in subpart M
of this part, EPA will notify the person(s) who originally reported the microorganism that another person
(whose identity will remain confidential, if so requested) has demonstrated a bona fide intent to
manufacture, import, or process the microorganism and therefore was told that the microorganism is on
the Inventory, in §725.239, or in subpart M of this part.
(g) A disclosure to a person with a bona fide intent to manufacture, import, or process a particular
microorganism that the microorganism is on the Inventory, in §725.239, or in subpart M of this part will
not be considered a public disclosure of confidential business information under section 14 of the Act.
(h) EPA will answer an inquiry on whether a particular microorganism is subject to this part within 30
days after receipt of a complete submission under paragraph (b) of this section.

§ 725.17 Consultation with EPA.

section, if a person intends to manufacture or import a new microorganism which is subject to the
notification requirements of this part, and the microorganism is subject to a test rule promulgated under
section 4 of the Act before the notice is submitted, section 5(b)(1) of the Act requires the person to
submit the test data required by the testing rule with the notice. The person must submit the data in the
form and manner specified in the test rule and in accordance with §725.160. If the person does not
submit the test data, the submission is incomplete and EPA will follow the procedures in §725.33.
(2) If EPA has granted the submitter an exemption under section 4(c) of the Act from the requirement to
conduct tests and submit data, the person may not file a MCAN or TERA until EPA receives the test
data.
(3) If EPA has granted the submitter an exemption under section 4(c) of the Act and if another person
previously has submitted the test data to EPA, the exempted person may either submit the test data or
provide the following information as part of the notice:
(i) The name, title, and address of the person who submitted the test data to EPA.
(ii) The date the test data were submitted to EPA.

specific microorganism identity under this paragraph must provide one of the following items at the time
the submission is filed:
(i) The generic name which was accepted by EPA in the prenotice consultation conducted under
paragraph (a)(4) of this section.
(ii) One generic name that is only as generic as necessary to protect the confidential identity of the
particular microorganism. The name should reveal the specific identity to the maximum extent possible.
The generic name will be subject to EPA review and approval.
(4) Determination by EPA. (i) Any person who intends to assert a claim of confidentiality for the specific
identity of a new microorganism may seek a determination by EPA of an appropriate generic name for
the microorganism before filing a submission. For this purpose, the person should submit to EPA:
(A) The specific identity of the microorganism.
(B) A proposed generic name(s) which is only as generic as necessary to protect the confidential identity
of the new microorganism. The name(s) should reveal the specific identity of the microorganism to the
maximum extent possible.
(ii) Within 30 days, EPA will inform the submitter either that one of the proposed generic names is
adequate or that none is adequate and further consultation is necessary.
(5) Use of generic name. If a submitter claims microorganism identity as confidential under paragraph
(a) of this section, and if the submitter complies with paragraph (a)(2) of this section, EPA will issue for
publication in theFederal Registernotice described in §725.40 the generic name proposed by the
submitter or one agreed upon by EPA and the submitter.

(b) Claims applicable to the period after commencement of manufacture or import for general
commercial use —(1) Maintaining claim. Any claim of confidentiality under paragraph (a) of this section
is applicable only until the microorganism is manufactured or imported for general commercial use and
becomes eligible for inclusion on the Inventory. To maintain the confidential status of the microorganism
identity when the microorganism is added to the Inventory, a submitter must reassert the confidentiality
claim and substantiate the claim in the notice of commencement of manufacture required under
§725.190.
(i) A submitter may not claim the microorganism identity confidential for the period after commencement
of manufacture or import for general commercial use unless the submitter claimed the microorganism
identity confidential under paragraph (a) of this section in the MCAN submitted for the microorganism.
(ii) A submitter may claim the microorganism identity confidential for the period after commencement of
manufacture or import for general commercial use if the submitter did not claim the microorganism
identity confidential under paragraph (a) of this section in any TERA submitted for the microorganism,
but subsequently did claim microorganism identity confidential in the MCAN submitted for the
microorganism.
(2) Assertion of claim. (i) A person who believes that public disclosure of the fact that anyone
manufactures or imports the microorganism for general commercial use would reveal confidential
business information may assert a claim of confidentiality under paragraph (b) of this section.
(ii) If the notice includes a health and safety study concerning the new microorganism, and if the claim
for confidentiality with respect to the microorganism identity is denied in accordance with §725.92(c),
EPA will deny a claim asserted under paragraph (b) of this section.
(3) Requirements for assertion. Any person who asserts a confidentiality claim for microorganism identity
must:
(i) Comply with the requirements of paragraph (a)(3) of this section regarding submission of a generic
name.
(ii) Agree that EPA may disclose to a person with a bona fide intent to manufacture or import the
microorganism the fact that the particular microorganism is included on the confidential Inventory for
purposes of notification under section 5(a)(1)(A) of the Act.
(iii) Have available and agree to furnish to EPA upon request the taxonomic designations and
supplemental information required by §725.12.
(iv) Provide a detailed written substantiation of the claim, in accordance with the requirements of
§725.94(b).
(4) Denial of claim. If the submitter does not meet the requirements of paragraph (b) of this section, EPA
will deny the claim of confidentiality.
(5) Acceptance of claim. (i) EPA will publish a generic name on the public Inventory if:
(A) The submitter asserts a claim of confidentiality in accordance with this paragraph.
(B) No claim for confidentiality of the microorganism identity as part of a health and safety study has
been denied in accordance with part 2 of this title or §725.92.
(ii) Publication of a generic name on the public Inventory does not create a category for purposes of the
Inventory. Any person who has a bona fide intent to manufacture or import a microorganism which is
described by a generic name on the public Inventory may submit an inquiry to EPA under §725.15(b) to
determine whether the particular microorganism is included on the confidential Inventory.
(iii) Upon receipt of a request described in §725.15(b), EPA may require the submitter who originally
asserted confidentiality for a microorganism to submit to EPA the information listed in paragraph (b)(3)
(iii) of this section.
(iv) Failure to submit any of the information required under paragraph (b)(3)(iii) of this section within 10
calendar days of receipt of a request by EPA under paragraph (b) of this section will constitute a waiver

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

of the original submitter's confidentiality claim. In this event, EPA may place the specific microorganism
identity on the public Inventory without further notice to the original submitter.
(6) Use of generic name on the public Inventory. If a submitter asserts a claim of confidentiality under
paragraph (b) of this section, EPA will examine the generic microorganism name proposed by the
submitter.
(i) If EPA determines that the generic name proposed by the submitter is only as generic as necessary
to protect the confidential identity of the particular microorganism, EPA will place that generic name on
the public Inventory.
(ii) If EPA determines that the generic name proposed by the submitter is more generic than necessary
to protect the confidential identity, EPA will propose in writing, for review by the submitter, an alternative
generic name that will reveal the identity of the microorganism to the maximum extent possible.
(iii) If the generic name proposed by EPA is acceptable to the submitter, EPA will place that generic
name on the public Inventory.
(iv) If the generic name proposed by EPA is not acceptable to the submitter, the submitter must explain
in detail why disclosure of that generic name would reveal confidential business information and propose
another generic name which is only as generic as necessary to protect the confidential identity of the
microorganism. If EPA does not receive a response from the submitter within 30 days after the submitter
receives the proposed name, EPA will place EPA's chosen generic name on the public Inventory. If the
submitter does provide the information requested, EPA will review the response. If the submitter's
proposed generic name is acceptable, EPA will publish that generic name on the public Inventory. If the
submitter's proposed generic name is not acceptable, EPA will notify the submitter of EPA's choice of a
generic name. Thirty days after this notification, EPA will place the chosen generic name on the public
Inventory.

§ 725.88 Uses of a microorganism.
top
(a) Assertion of claim. A person who submits information to EPA under this part on the categories or
proposed categories of use of a microorganism may assert a claim of confidentiality for this information.
(b) Requirements for claim. A submitter that asserts such a claim must:
(1) Report the categories or proposed categories of use of the microorganism.

development or marketing plans, and advertising plans, for which the person submits a claim of
confidentiality in accordance with §725.80.
(b) Microorganism identity —(1) Claims applicable to the period prior to commencement of manufacture
or import for general commercial use. A claim of confidentiality for the period prior to commencement of
manufacture or import for general commercial use for the specific identity of a microorganism for which a
health and safety study was submitted must be asserted in conjunction with a claim asserted under
§725.85(a). The submitter must substantiate each claim in accordance with the requirements of §725.94
(a).
(2) Claims applicable to the period after commencement of manufacture or import for general
commercial use. To maintain the confidential status of the specific identity of a microorganism for which
a health and safety study was submitted after commencement of manufacture or import for general
commercial use, the claim must be reasserted and substantiated in conjunction with a claim under
§725.85(b). The submitter must substantiate each claim in accordance with the requirements of §725.94
(b).
(c) Denial of confidentiality claim. EPA will deny a claim of confidentiality for microorganism identity
under paragraph (b) of this section, unless:
(1) The information would disclose processes used in the manufacture or processing of a
microorganism.
(2) The microorganism identity is not necessary to interpret a health and safety study.
(d) Use of generic names. When EPA discloses a health and safety study containing a microorganism
identity, which the submitter has claimed confidential, and if the Agency has not denied the claim under
paragraph (c) of this section, EPA will identify the microorganism by the generic name selected under
§725.85.

§ 725.94 Substantiation requirements.
top
(a) Claims applicable to the period prior to commencement of manufacture or import for general
commercial use —(1) MCAN, TME, Tier I certification, and Tier II exemption request requirements. Any

(i) What harmful effects to the company's or institution's competitive position, if any, would result if EPA
publishes on the Inventory the identity of the microorganism? How could a competitor use such
information given the fact that the identity of the microorganism otherwise would appear on the TSCA
Inventory with no link between the microorganism and the company or institution? How substantial
would the harmful effects of disclosure be? What is the causal relationship between the disclosure and
the harmful effects?
(ii) Has the identity of the microorganism been kept confidential to the extent that competitors do not
know it is being manufactured or imported for general commercial use by anyone?
(c) General questions. The following questions must be answered in detail for each confidentiality claim:
(1) For what period of time is a claim of confidentiality being asserted? If the claim is to extend until a
certain event or point in time, indicate that event or time period. Explain why the information should
remain confidential until such point.
(2) Briefly describe any physical or procedural restrictions within the company or institution relating to the
use and storage of the information claimed as confidential. What other steps, if any, apply to use or
further disclosure of the information?
(3) Has the information claimed as confidential been disclosed to individuals outside of the company or
institution? Will it be disclosed to such persons in the future? If so, what restrictions, if any, apply to use
or further disclosure of the information?
(4) Does the information claimed as confidential appear, or is it referred to, in any of the following
questions? If the answer is yes to any of these questions, indicate where the information appears and
explain why it should nonetheless be treated as confidential.
(i) Advertising or promotional materials for the microorganism or the resulting end product?
(ii) Material safety data sheets or other similar materials for the microorganism or the resulting end
product?
(iii) Professional or trade publications?
(iv) Any other media available to the public or to competitors?
(v) Patents?
(vi) Local, State, or Federal agency public files?
(5) Has EPA, another Federal agency, a Federal court, or a State made any confidentiality determination
regarding the information claimed as confidential? If so, provide copies of such determinations.
(6) For each type of information claimed confidential, describe the harm to the company's or institution's
competitive position that would result if this information were disclosed. Why would this harm be
substantial? How could a competitor use such information? What is the causal connection between the
disclosure and harm?
(7) If EPA disclosed to the public the information claimed as confidential, how difficult would it be for the
competitor to enter the market for the resulting product? Consider such constraints as capital and
marketing cost, specialized technical expertise, or unusual processes.
(d) Microorganism identity and production method. If confidentiality claims are asserted for the identity of
the microorganism or information on how the microorganism is produced, the following questions must
be answered:
(1) Has the microorganism or method of production been patented in the U.S. or elsewhere? If so, why
is confidentiality necessary?
(2) Does the microorganism leave the site of production or testing in a form which is accessible to the
public or to competitors? What is the cost to a competitor, in time and money, to develop appropriate

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

use conditions? What factors facilitate or impede product analysis?
(3) For each additional type of information claimed as confidential, explain what harm would result from
disclosure of each type of information if the identity of the microorganism were to remain confidential.
(e) Health and safety studies of microorganisms. If confidentiality claims are asserted for information in a
health or safety study of a microorganism, the following questions must be answered:
(1) Would the disclosure of the information claimed confidential reveal: confidential process information,
or information unrelated to the effects of the microorganism on health and the environment. Describe the
causal connection between the disclosure and harm.
(2) Does the company or institution assert that disclosure of the microorganism identity is not necessary
to interpret any health and safety studies which have been submitted? If so, explain how a less specific
identity would be sufficient to interpret the studies.

§ 725.95 Public file.
top
All information submitted, including any health and safety study of a microorganism and other supporting
documentation, will become part of the public file for that submission, unless such materials are claimed
confidential. In addition, EPA may add materials to the public file, unless such materials are claimed

Subpart D—Microbial Commercial Activities Notification Requirements
top

§ 725.100 Scope and purpose.
top
(a) This subpart establishes procedures for submission of a notice to EPA under section 5(a) of the Act
for persons who manufacture, import, or process microorganisms for commercial purposes. This notice
is called a Microbial Commercial Activity Notice (MCAN). It is expected that MCANs will in general only
be submitted for microorganisms intended for general commercial use. Persons who manufacture,
import, or process a microorganism in small quantities solely for research and development as defined in
§725.3 are not required to submit a notice to EPA. Persons who manufacture, import, or process a
microorganism for research and development activities that do not fit the definition of small quantities
solely for research and development may nonetheless qualify for more limited reporting requirements in
Subpart E, including the TERA which can be used for review of research and development involving
environmental release.
(b) Persons subject to MCAN submission are described in §725.105.
(c) Exclusions and exemptions specific to MCAN submissions are described in §725.110.
(d) Submission requirements applicable specifically to MCANs are described at §725.150.
(e) Data requirements for MCANs are set forth in §§725.155 and 725.160.
(f) EPA review procedures specific to MCANs are set forth in §725.170.
(g) Subparts A through C of this part apply to any MCAN submitted under this subpart.

described in §725.110.
(2) If a person contracts with a manufacturer to produce or process a new microorganism and the
manufacturer produces or processes the microorganism exclusively for that person, and that person
specifies the identity of the microorganism, and controls the total amount produced and the basic
technology for the plant process, then that person must submit the MCAN. If it is unclear who must
report, EPA should be contacted to determine who must submit the MCAN.
(3) Only manufacturers that are incorporated, licensed, or doing business in the United States may
submit a MCAN.
(b) Importers of new microorganisms. (1) MCAN submission is required for a person who intends to
import into the United States for commercial purposes a new microorganism. Exclusions are described
in §725.110.
(2) When several persons are involved in an import transaction, the MCAN must be submitted by the
principal importer. If no one person fits the principal importer definition in a particular transaction, the
importer should contact EPA to determine who must submit the MCAN for that transaction.
(3) Except as otherwise provided in paragraph (b)(4) of this section, the provisions of this subpart D
apply to each person who submits a MCAN for a new microorganism which such person intends to
import for a commercial purpose. In addition, each importer must comply with paragraph (b)(4) of this
section.
(4) EPA will hold the principal importer, or the importer that EPA determines must submit the MCAN
when there is no principal importer under paragraph (b)(2) of this section, liable for complying with this
part, for completing the MCAN, and for the completeness and truthfulness of all information which it
submits.
(c) Manufacturers, importers, or processors of microorganisms for a significant new use. MCAN
submission is required for any person who intends to manufacture, import, or process for commercial
purposes a microorganism identified as having one or more significant new uses in subpart M of this
part, and who intends either to engage in a designated significant new use of the microorganism or
intends to distribute it in commerce. Persons excluded from reporting on significant new uses of
microorganisms and additional procedures for reporting are described in subpart L of this part.

§ 725.110 Persons not subject to this subpart.

§ 725.170 EPA review of the MCAN.
top
General procedures for review of all submissions under this part are contained in §§725.28 through
725.60. In addition, the following procedures apply to EPA review of MCANs submitted under this
subpart:
(a) Length of the review period. The MCAN review period specified in section 5(a) of the Act runs for 90
days from the date the Document Control Officer for the Office of Pollution Prevention and Toxics
receives a complete MCAN, or the date EPA determines the MCAN is complete under §725.33, unless
the Agency extends the period under section 5(c) of the Act and §725.56.
(b) Notice of expiration of MCAN review period. (1) EPA will notify the submitter that the MCAN review
period has expired or that EPA has completed its review of the MCAN. Expiration of the review period
does not constitute EPA approval or certification of the new microorganism, and does not mean that
EPA may not take regulatory action against the microorganism in the future.
(2) After expiration of the MCAN review period, in the absence of regulatory action by EPA under section
5(e), 5(f), or 6(a) of the Act, the submitter may manufacture or import the microorganism even if the
submitter has not received notice of expiration.
(3) Early notification that EPA has completed its review does not permit commencement of manufacture
or import prior to the expiration of the 90–day MCAN review period.
(c) No person submitting a MCAN in response to the requirements of this subpart may manufacture,
import, or process a microorganism subject to this subpart until the review period, including all
extensions and suspensions, has expired.

(1) The structural gene(s) of interest.
(2) The regulatory sequences permitting the expression of solely the gene(s) of interest.
(3) Associated nucleotide sequences needed to move genetic material, including linkers, homopolymers,
adaptors, transposons, insertion sequences, and restriction enzyme sites.
(4) The nucleotide sequences needed for vector transfer.
(5) The nucleotide sequences needed for vector maintenance.
(b) Well-characterized. For introduced genetic material, well-characterized means that the following have
been determined:
(1) The function of all of the products expressed from the structural gene(s).
(2) The function of sequences that participate in the regulation of expression of the structural gene(s).

(c) Poorly mobilizable. The ability of the introduced genetic material to be transferred and mobilized is
inactivated, with a resulting frequency of transfer of less than 10−8transfer events per recipient.
(d) Free of certain sequences. (1) The introduced genetic material must not contain a functional portion
of any of the toxin-encoding sequences described in this paragraph (d).
(i) For the purposes of this section, a functional portion of a toxin-encoding sequence means any
sequence which codes for a polypeptide that has one of the following effects:
(A) It directly or indirectly contributes to toxic effects in humans. Directly contributes to toxic effects in
humans means those sequences encoding polypeptides that have direct toxicity to target cells. An
example of a sequence which directly contributes to toxic effects in humans is one which encodes the
portion of diphtheria toxin, listed in paragraph (d)(2) of this section, capable of interacting with elongation
factor 2, leading to inhibition of protein synthesis in target respiratory, heart, kidney, and nerve tissues.
Indirectly contributes to toxic effects in humans means a sequence whose encoded polypeptide is not
directly toxic to target cells, yet still adversely affects humans. An example of a sequence which
indirectly contributes to toxic effects is the sequence which encodes the portion of the botulinum toxin,
listed in paragraph (d)(3) of this section, capable of blocking the release of acetylcholine from
gangliosides. Botulinum toxin affects neuromuscular junctions by its blockage of acetylcholine release,
leading to irreversible relaxation of muscles and respiratory arrest.
(B) It binds a toxin or toxin precursor to target human cells.
(C) It facilitates intracellular transport of a toxin in target human cells.
(ii) While these toxins are listed (with synonyms in parentheses) in paragraphs (d)(2) through (d)(7) of
this section according to the source organism, it is use of the nucleotide sequences that encode the
toxins that is being restricted and not the use of the source organisms. The source organisms are listed
to provide specificity in identification of sequences whose use is restricted. Although similar or identical
sequences may be isolated from organisms other than those listed below in paragraphs (d)(2) through
(d)(7) of this section, these comparable toxin sequences, regardless of the organism from which they are
derived, must not be included in the introduced genetic material.
(2) Sequences for protein synthesis inhibitor.

described in the request will not present an unreasonable risk to health or the environment.
(2) If the Agency makes this determination, the Administrator, or a designee will notify the manufacturer
or importer by telephone, followed by a letter, that the request has been denied. The letter will explain
reasons for the denial.
(3) If the request is denied, the manufacturer or importer may submit the information necessary to
constitute a MCAN under subpart D of this part.
(e) Approval or denial of the Tier II exemption request. (1) No later than 45 days after EPA receives a
request, the Agency will either approve or deny the request.
(2) In approving a request, EPA may impose any restrictions necessary to ensure that the
microorganism will not present an unreasonable risk of injury to health and the environment as a result
of general commercial use.
(f) EPA may seek to enjoin the manufacture or import of a microorganism in violation of this subpart, or
act to seize any microorganism manufactured or imported in violation of this section or take other actions
under the authority of sections 7 or 17 of the Act.
(g) A manufacturer or importer may only proceed after receipt of EPA approval.

(a) In certain sections of subpart M of this part, significant new uses for the identified microorganisms
are described as the failure to establish and implement programs providing for the use of either: specific
measures to control worker exposure to or release of microorganisms which are identified in such
sections, or alternative measures to control worker exposure or environmental release which EPA has
determined provide substantially the same degree of protection as the specified control measures.
Persons who manufacture, import, or process a microorganism identified in such sections and who
intend to employ alternative measures to control worker exposure or environmental release must submit
a request to EPA for a determination of equivalency before commencing manufacture, import, or
processing involving the alternative control measures.
(b) A request for a determination of equivalency must be submitted in writing to the Office of Pollution
Prevention and Toxics, Document Control Officer, 7407, 1200 Pennsylvania Ave., NW., Washington, DC
20460: ATTN: SNUR Equivalency Determination, and must contain:
(1) The name of the submitter.
(2) The specific identity of the microorganism.
(3) The citation for the specific section in subpart M of this part which pertains to the microorganism for
which the request is being submitted.
(4) A detailed description of the activities involved.
(5) The specifications of the alternative worker exposure control measures or environmental release
control measures.
(6) A detailed analysis explaining why such alternative control measures provide substantially the same
degree of protection as the specific control measures identified in the specific section in subpart M of this
part which pertains to the microorganism for which the request is being submitted.
(7) The data and information described in §§725.155 and 725.160. If such data and information have
already been submitted to EPA's Office of Pollution Prevention and Toxics, the submitter need only
document that it was previously submitted, to whom, and the date it was submitted.
(c) Requests for determinations of equivalency will be reviewed by EPA within 45 days. Determinations
under this paragraph will be made by the Director, or a designee. Notice of the results of such
determinations will be mailed to the submitter.
(d) If EPA notifies the submitter under paragraph (c) of this section that EPA has determined that the
alternative control measures provide substantially the same degree of protection as the specified control
measures identified in the specific section of subpart M of this part which pertains to the microorganism
for which the request is being submitted, the submitter may commence manufacture, import, or
processing in accordance with the specifications for alternative worker exposure control measures or
environmental release control measures identified in the submitter's request, and may alter any
corresponding notification to workers to reflect such alternative controls. Deviations from the activities
described in the EPA notification constitute a significant new use and are subject to the requirements of
this part.

§ 725.980 Expedited procedures for issuing significant new use rules for
microorganisms subject to section 5(e) orders.
top
(a) Selection of microorganisms. (1) In accordance with the expedited process specified in this section,
EPA will issue significant new use notification requirements for each new microorganism that, after
MCAN review under subpart D of this part, becomes subject to a final order issued under section 5(e) of
the Act, except for an order that prohibits manufacture and import of the microorganism, unless EPA
determines that significant new use notification requirements are not needed for the microorganism.
(2) If EPA determines that significant new use notifications requirements are not needed for a
microorganism that is subject to a final order issued under section 5(e) of the Act, EPA will issue a notice
in theFederal Registerexplaining why the significant new use requirements are not needed.

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

Electronic Code of Federal Regulations:

Page 54 of 57

(b) Designation of requirements. (1) The significant new use notification and other specific requirements
will be based on and be consistent with the provisions included in the final order issued for the
microorganism under section 5(e) of the Act. EPA may also designate additional activities as significant
new uses which will be subject to notification.
(2) Significant new use requirements and other specific requirements designated under this section will
be listed in subpart M of this part. For each microorganism, subpart M of this part will identify:
(i) The microorganism name.
(ii) The activities designated as significant new uses.
(iii) Other specific requirements applicable to the microorganism, including recordkeeping requirements
or any other requirements included in the final section 5(e) order.
(c) Procedures for issuing significant new use rules —(1) Possible processes. EPA will issue significant
new use rules (SNURs) under this section by one of the following three processes: direct final
rulemaking, interim final rulemaking, or notice and comment rulemaking. EPA will use the direct final
rulemaking process to issue significant new use rules unless it determines that, in a particular case, one
of the other processes is more appropriate.
(2) Notice in the Federal Register. Federal Registerdocuments issued to propose or establish significant
new uses under this section will contain the following:
(i) The microorganism identity or, if its specific identity is claimed confidential, an appropriate generic
microorganism name and an accession number assigned by EPA.
(ii) The MCAN number.
(iii) A summary of EPA's findings under section 5(e)(1)(A) of the Act for the final order issued under
section 5(e).
(iv) Designation of the significant new uses subject to, or proposed to be subject to, notification and any
other applicable requirements.
(v) Any modification of subpart L of this part applicable to the specific microorganism and significant new
uses.
(vi) If theFederal Registerdocument establishes a final rule, or notifies the public that a final rule will not
be issued after public comment has been received, the document will describe comments received and
EPA's response.
(3) Direct final rulemaking. (i) EPA will use direct final rulemaking to issue a significant new use rule,
when specific requirements will be based on and be consistent with the provisions included in the final
order issued for the microorganism under section 5(e) of the Act. EPA will issue a final rule in theFederal
Registerfollowing its decision to develop a significant new use rule under this section for a specific new
microorganism.
(ii) TheFederal Registerdocument will state that, unless written notice is received by EPA within 30 days
of publication that someone wishes to submit adverse or critical comments, the rule will be effective 60
days from the date of publication. The written notice of intent to submit adverse or critical comments
should state which SNUR(s) will be the subject of the adverse or critical comments, if several SNURs
are established through the direct final rule. If notice is received within 30 days that someone wishes to
submit adverse or critical comments, the section(s) of the direct final rule containing the SNUR(s) for
which a notice of intent to comment was received will be withdrawn by EPA issuing a document in the
final rule section of theFederal Register,and a proposal will be published in the proposed rule section of
theFederal Register.The proposal will establish a 30–day comment period.
(iii) If EPA, having considered any timely comments submitted in response to the proposal, decides to
establish notification requirements under this section, EPA will issue a final rule adding the
microorganism to subpart M of this part and designating the significant new uses subject to notification.
(4) Interim final rulemaking. (i) EPA will use the interim final rulemaking procedure to issue a significant

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

new use rule, when specific requirements will be based on and be consistent with the provisions
included in the final order issued for the microorganism under section 5(e) of the Act. The Agency will
issue an interim final rule in theFederal Registerfollowing its decision to develop a significant new use
rule for a specific new microorganism. The document will state EPA's reasons for using the interim final
rulemaking procedure.
(A) The significant new use rule will take effect on the date of publication.
(B) Persons will be given 30 days from the date of publication to submit comments.
(ii) Interim final rules issued under this section shall cease to be in effect 180 days after publication
unless, within the 180–day period, EPA issues a final rule in theFederal Registerresponding to any
written comments received during the 30–day comment period specified in paragraph (c)(4)(i)(B) of this
section and promulgating final significant new use notification requirements and other requirements for
the microorganism.
(5) Notice and comment rulemaking. (i) EPA will use a notice and comment procedure to issue a
significant new use rule, when EPA is designating additional activities which are not provisions included
in the final order issued for the microorganism under section 5(e) of the Act as significant new uses
which will be subject to notification. EPA will issue a proposal in theFederal Registerfollowing its decision
to develop a significant new use rule under this section for a specific new microorganism. Persons will
be given 30 days to comment on whether EPA should establish notification requirements for the
microorganism under this part.
(ii) If EPA, having considered any timely comments, decides to establish notification requirements under
this section, EPA will issue a final rule adding the microorganism to subpart M of this part and
designating the significant new uses subject to notification.
(d) Schedule for issuing significant new use rules. (1) Unless EPA determines that a significant new use
rule should not be issued under this section, EPA will issue a proposed rule, a direct final rule, or an
interim final rule within 180 days of receipt of a valid notice of commencement under §725.190.
(2) If EPA receives adverse or critical significant comments following publication of a proposed or interim
final rule, EPA will either withdraw the rule or issue a final rule addressing the comments received.

§ 725.984 Modification or revocation of certain notification requirements.
top
(a) Criteria for modification or revocation. EPA may at any time modify or revoke significant new use
notification requirements for a microorganism which has been added to subpart M of this part using the
procedures of §725.980. Such action may be taken under this section if EPA makes one of the following
determinations, unless other information shows that the requirements should be retained:
(1) Test data or other information obtained by EPA provide a reasonable basis for concluding that
activities designated as significant new uses of the microorganism will not present an unreasonable risk
of injury to health or the environment.
(2) EPA has promulgated a rule under section 4 or 6 of the Act, or EPA or another agency has taken
action under another law, for the microorganism that eliminates the need for significant new use
notification under section 5(a)(2) of the Act.
(3) EPA has received MCANs for some or all of the activities designated as significant new uses of the
microorganism and, after reviewing such MCANs, concluded that there is no need to require additional
notice from persons who propose to engage in identical or similar activities.
(4) EPA has examined new information, or has reexamined the test data or other information supporting
its finding under section 5(e)(1)(A)(ii)(I) of the Act and has concluded that a rational basis no longer
exists for the findings that activities involving the microorganism may present an unreasonable risk of
injury to health or the environment required under section 5(e)(1)(A) of the Act.
(5) Certain activities involving the microorganism have been designated as significant new uses pending

http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&sid=589e7c57832dda3c79ef607a8d9... 12/17/2009

the completion of testing, and adequate test data developed in accordance with applicable procedures
and criteria have been submitted to EPA.
(b) Procedures for limitation or revocation. Modification or revocation of significant new use notification
requirements for a microorganism that has been added to subpart M of this part using the procedures
described in §725.980 may occur either at EPA's initiative or in response to a written request.
(1) Any affected person may request modification or revocation of significant new use notification
requirements for a microorganism that has been added to subpart M of this part using the procedures
described in §725.980 by writing to the Director, or a designee, and stating the basis for such request.
The request must be accompanied by information sufficient to support the request. All requests should
be sent to the TSCA Document Processing Center (7407), Room L–100, U.S. Environmental Protection
Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460, ATTN: Request to amend SNUR.
(2) The Director, or a designee, will consider the request, make a determination whether to initiate
rulemaking to modify the requirements, and notify the requester of that determination by certified letter. If
the request is denied, the letter will explain why EPA has concluded that the significant new use
notification requirements for that microorganism should remain in effect.
(3) If EPA concludes that significant new use notification requirements for a microorganism should be
limited or revoked, EPA will propose the changes in a notice in theFederal Register,briefly describe the
grounds for the action, and provide interested parties an opportunity to comment.
