Subpart A—General Provisions and Applicability 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

§ 725.1 Scope and purpose. 

(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. 

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 EPA) as a result of a 

prenotice agreement with EPA. 

Containment and/or inactivation controls means any combination of engineering, mechanical, procedural, or 

biological controls designed and operated to restrict environmental release of viable microorganisms from a 

structure. 

Director means the Director of the EPA Office of Pollution Prevention and Toxics. 

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 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.

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

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.

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

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. 

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. 

(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: 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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. 

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. 

(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. 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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 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.

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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. 

Persons may consult with EPA, either in writing or by telephone, about their obligations under this part. Written 

consultation is preferred. Written inquiries should be sent to the following address: Environmental Assistance 

Division (7408), Office of Pollution Prevention and Toxics, U.S. Environmental Protection Agency, 1200 

Pennsylvania Ave., NW., Washington, DC 20460, ATTN: Biotechnology Notice Consultation. Persons wishing to

following criteria should be addressed in an application to list a recipient microorganism under §725.420: 

(A) Identification and classification of the microorganism using available genotypic and phenotypic information; 

(B) Information to evaluate the relationship of the microorganism to any other closely related microorganisms 

which have a potential for adverse effects on health or the environment; 

(C) A history of safe commercial use for the microorganism; 

(D) Commercial uses indicating that the microorganism products might be subject to TSCA; 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(E) Studies which indicate the potential for the microorganism to cause adverse effects to health or the 

environment; and 

(F) Studies which indicate the survival characteristics of the microorganism in the environment. 

(b) Processing of the Letter of Application by EPA —(1) Grant of the Application. If, after consideration of the 

Letter of Application and any other relevant information available to EPA, the Assistant Administrator for 

Prevention, Pesticides and Toxic Substances makes a preliminary determination that the new microorganism will 

not present an unreasonable risk of injury to health or the environment, the Assistant Administrator will propose a 

rule to grant the exemption using the applicable procedures in part 750 of this chapter. 

(2) Denial of the application. If the Assistant Administrator decides that the preliminary determination described 

in paragraph (b)(1) of this section cannot be made, the application will be denied by sending the applicant a 

written statement with the Assistant Administrator's reasons for denial. 

(c) Processing of the exemption —(1) Unreasonable risk standard. Granting a section 5(h)(4) exemption requires 

a determination that the activities will not present an unreasonable risk of injury to health or the environment. 

(i) An unreasonable risk determination under the Act is an administrative judgment that requires balancing of the 

harm to health or the environment that a chemical substance may cause and the magnitude and severity of that 

harm, against the social and economic effects on society of EPA action to reduce that harm. 

(ii) A determination of unreasonable risk under section 5(h)(4) of the Act will examine the reasonably 

ascertainable economic and social consequences of granting or denying the exemption after consideration of the 

effect on the national economy, small business, technological innovation, the environment, and public health. 

(2) Grant of the exemption. The exemption will be granted if the Assistant Administrator determines, after 

consideration of all relevant evidence presented in the rulemaking proceeding described in paragraph (b)(1) of this 

section, that the new microorganism will not present an unreasonable risk of injury to health or the environment. 

(3) Denial of the exemption. The exemption will be denied if the Assistant Administrator determines, after 

consideration of all relevant evidence presented in the rulemaking proceeding described in paragraph (b)(1) of this 

section, that the determination described in paragraph (c)(2) of this section cannot be made. A final decision 

terminating the rulemaking proceeding will be published in the Federal Register .

§ 725.85 Microorganism identity. 

(a) Claims applicable to the period prior to commencement of manufacture or import for general commercial use 

—(1) When to make a claim. (i) A person who submits information to EPA under this part may assert a claim of 

confidentiality for portions of the specific microorganism identity at the time of submission of the information. 

This claim will apply only to the period prior to the commencement of manufacture or import for general 

commercial use. 

(ii) A person who submits information to EPA under this part must reassert a claim of confidentiality and 

substantiate the claim each time the information is submitted to EPA. For example, if a person claims certain 

information confidential in a TERA submission and wishes the same information to remain confidential in a 

subsequent TERA or MCAN submission, the person must reassert and resubstantiate the claim in the subsequent 

submission. 

(2) Assertion of claim. (i) A submitter may assert a claim of confidentiality only if the submitter believes that 

public disclosure prior to commencement of manufacture or import for general commercial use of the fact that 

anyone is initiating research and development activities pertaining to the specific microorganism or intends to 

manufacture or import the specific microorganism for general commercial use would reveal confidential business 

information. Claims must be substantiated in accordance with the requirements of §725.94(a). 

(ii) If the submission includes a health and safety study concerning the microorganism and if the claim for 

confidentiality with respect to the specific identity is denied in accordance with §725.92(c), EPA will deny a 

claim asserted under paragraph (a) of this section. 

(3) Development of generic name. Any person who asserts a claim of confidentiality for portions of the 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. 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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 the 

 Federal Register notice 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. 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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 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. 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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. 

(2) Provide, in nonconfidential form, a description of the uses that is only as generic as necessary to protect the 

confidential business information. The generic use description will be included in the Federal Register notice 

described in §725.40. 

(c) Generic use description. The person must submit the information required by paragraph (b) of this section by 

describing the uses as precisely as possible, without revealing the information which is claimed confidential, to 

disclose as much as possible how the use may result in human exposure to the microorganism or its release to the 

environment. 

§ 725.92 Data from health and safety studies of microorganisms. 

(a) Information other than specific microorganism identity. Except as provided in paragraph (b) of this section, 

EPA will deny any claim of confidentiality with respect to information included in a health and safety study of a 

microorganism, unless the information would disclose confidential business information concerning: 

(1) Processes used in the manufacture or processing of a microorganism. 

(2) Information which is not in any way related to the effects of a microorganism on health or the environment, 

such as, the name of the submitting company, cost or other financial data, product 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.

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

§ 725.94 Substantiation requirements. 

(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 person who submits a 

MCAN, TME, Tier I certification, or Tier II exemption request should strictly limit confidentiality claims to that 

information which is confidential and proprietary to the business. 

(i) If any information in the submission is claimed as confidential business information, the submitter must 

substantiate each claim by submitting written answers to the questions in paragraphs (c), (d), and (e) of this 

section at the time the person submits the information. 

(ii) If the submitter does not provide written substantiation as required in paragraph (a)(1)(i) of this section, the 

submission will be considered incomplete and the review period will not begin in accordance with §725.33. 

(2) TERA requirements. Any person who submits a TERA, should strictly limit confidentiality claims to that 

information which is confidential and proprietary to the business. If any information in such a submission is 

claimed as confidential business information, the submitter must have available for each of those claims, and 

agree to furnish to EPA upon request, written answers to the questions in paragraphs (d) and (e) of this section. 

(b) Claims applicable to the period after commencement of manufacture or import for general commercial use. 

(1) If a submitter claimed portions of the microorganism identity confidential in the MCAN and wants the identity 

to be listed on the confidential Inventory, the claim must be reasserted and substantiated at the time the Notice of 

Commencement (NOC) is submitted under §725.190. Otherwise, EPA will list the specific microorganism 

identity on the public Inventory. 

(2) The submitter must substantiate the claim for confidentiality of the microorganism identity by answering all of 

the questions in paragraphs (c), (d), and (e) in this section. In addition, the following questions must be answered: 

(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? 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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 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.

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

§ 725.95 Public file. 

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 confidential. 

Any of the nonconfidential material described in this subpart will be available for public inspection in the TSCA 

Public Docket Office, Rm. NE-B607, 401 M St., SW., Washington, DC, between the hours of noon to 4 p.m., 

Monday through Friday, excluding legal holidays. 

Subpart D—Microbial Commercial Activities Notification Requirements 

§ 725.100 Scope and purpose. 

(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. 

§ 725.105 Persons who must report. 

(a) Manufacturers of new microorganisms. (1) MCAN submission is required for any person who intends to 

manufacture for commercial purposes in the United States a new microorganism. Exclusions are 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. 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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. 

Persons are not subject to the requirements of this subpart for the following activities:

transposons, insertion sequences, and restriction enzyme sites. 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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). 

(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. 

(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 10−8

transfer 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.

§ 725.912 Exemptions. 

Persons identified in §725.105(c) are not required to submit a MCAN under subpart D of this part for a 

microorganism identified in subpart M of this part, unless otherwise specified in a specific section in subpart M, 

if: 

(a) The person submits a MCAN for the microorganism prior to the promulgation date of the section in subpart M 

of this part which identifies the microorganism, and the person receives written notification of compliance from 

EPA prior to the effective date of such section. The MCAN submitter must comply with any applicable 

requirement of section 5(b) of the Act. The MCAN must include the information and test data specified in section 

5(d)(1) of the Act. For purposes of this exemption, the specific section in subpart M of this part which identifies 

the microorganism and §§725.3, 725.15, 725.65, 725.70, 725.75, 725.100, and 725.900 apply; after the effective 

date of the section in subpart M of this part which identifies the microorganism, §§725.105 and 725.910 apply and 

§725.920 continues to apply. EPA will provide the MCAN submitter with written notification of compliance only 

if one of the following occurs: 

(1) EPA is unable to make the finding that the activities described in the MCAN will or may present an 

unreasonable risk of injury to health or the environment under reasonably foreseeable circumstances, or

§ 725.980 Expedited procedures for issuing significant new use rules for microorganisms subject 

to section 5(e) orders. 

(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 the Federal Register 

explaining why the significant new use requirements are not needed. 

(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. 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

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 Register documents 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 the Federal Register document 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 the Federal Register following its 

decision to develop a significant new use rule under this section for a specific new microorganism. 

(ii) The Federal Register document 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 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 

the Federal Register following 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 the Federal Register responding 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 the Federal Register following 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. 

(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. 
Proposed Rule; Electronic Reporting Under the Toxic Substances Control Act (RIN 2070-AJ75) 

Demonstration of Proposed Revisions to Existing Rules – 40 CFR 725

(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 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.
