(721.72    Hazard communication program. 

Whenever a substance is identified in subpart E of this part as being
subject to this section, a significant new use of that substance is any
manner or method of manufacture, import, or processing associated with
any use of that substance without establishing a hazard communication
program as described in this section. 

(a) Written hazard communication program. Each employer shall develop
and implement a written hazard communication program for the substance
in each workplace. The written program will, at a minimum, describe how
the requirements of this section for labels, MSDSs, and other forms of
warning material will be satisfied. The employer must make the written
hazard communication program available, upon request, to all employees,
contractor employees, and their designated representatives. The employer
may rely on an existing hazard communication program, including an
existing program established under the Occupational Health and Safety
Administration (OSHA) Hazard Communication Standard (29 CFR 1900.1200),
to comply with this paragraph provided that the existing hazard
communication program satisfies the requirements of this paragraph. The
written program shall include the 

following: 

(1) A list of each substance identified in subpart E of this part as
subject to this section known to be present in the work area. The list
must be maintained in the work area and must use the identity provided
on the appropriate MSDS for each substance required under paragraph (c)
of this section. The list may be compiled for the workplace or for
individual work areas. 

(2) The methods the employer will use to inform employees of the hazards
of non-routine tasks involving the substance, for example, the cleaning
of reactor vessels, and the hazards associated with the substance
contained in unlabeled pipes in their work area. 

(3) The methods the employer will use to inform contractors of the
presence of the substance in the employer's workplace and of the
provisions of this part applicable to the substance if employees of the
contractor work in the employer's workplace and are reasonably likely to
be exposed to the substance while in the employer's workplace. 

(b) Labeling. (1) Each employer shall ensure that each container of the
substance in the workplace is labeled in accordance with this paragraph
(b)(1). 

(i) The label shall, at a minimum, contain the following information: 

(A) A statement of health hazard(s) and precautionary measure(s) for the
substance, if any,  identified in subpart E of this part or by the
employer. 

(B) The identity by which the substance may be commonly recognized. 

(C) A statement of environmental hazard(s) and precautionary measure(s)
for the substance, if any, identified in subpart E of this part or by
the employer.  

(D) A statement of exposure and precautionary measure(s), if any,
identified in subpart E of this part or by the employer. 

(ii) The employer may use signs, placards, process sheets, batch
tickets, operating procedures, or other such written materials in lieu
of affixing labels to individual stationary process containers, as long
as the alternative method identifies the containers to which it is
applicable and conveys information specified by paragraph (b)(1)(i) of
this section. Any written materials must be readily accessible to the
employees in their work areas throughout each work shift. 

(iii) The employer need not label portable containers into which the
substance is transferred from labeled containers, and which are intended
only for the immediate use of the employee who performs the transfer. 

(iv) The employer shall not remove or deface an existing label on
incoming containers of the substance unless the container is immediately
relabeled with the information specified in paragraph (b)(1)(i) of this
section. 

(2) Each employer shall ensure that each container of the substance
leaving its workplace for distribution in commerce is labeled in
accordance with this paragraph. 

(i) The label shall, at a minimum, contain the following information: 

(A) The information required under paragraph (b)(1)(i) of this section. 

(B) The name and address of the manufacturer or a responsible party who
can provide additional information on the substance for hazard
evaluation and any appropriate emergency procedures. 

(ii) The label shall not conflict with the requirements of the Hazardous
Materials Transportation Act (18 U.S.C. 1801 et. seq.) and regulations
issued under that Act by the Department of Transportation. 

(3) The label, or alternative forms of warning, shall be legible and
prominently displayed. 

(4) The label, or alternative forms of warning, shall be in English;
however, the information may be repeated in other languages. 

(5) If the label or alternative form of warning is to be applied to a
mixture containing a substance identified in subpart E of this part as
subject to this section in combination with another substance identified
in subpart E of this part and/or a substance defined as a "hazardous 
chemical" under the Occupational Safety and Health Administration (OSHA)
Hazard Communication Standard (29 CFR 1900.1200), the employer may
prescribe on the label, MSDS,  or alternative form of warning, the
measures to control worker exposure or environmental release which the
employer determines provide the greatest degree of protection. However,
should these control measures differ from the applicable measures
required under subpart E of this part, the employer must seek a 
determination of equivalency for such alternative control measures
pursuant to (721.30 before prescribing them under this paragraph. 

(c) Material safety data sheets. (1) Each employer must obtain or
develop a MSDS for the substance. 

(2) Each MSDS shall contain, at a minimum, the following information:

(vii) Precautionary measures to control worker exposure and/or
environmental release identified in subpart E of this part for the
substance, or alternative control measures which EPA has determined
under (721.30 provide substantially the same degree of protection as the
identified control measures. 

(viii) Any generally applicable precautions for safe handling and use of
the substance which are known to the employer, including appropriate
hygienic practices, protective measures during repair and maintenance of
contaminated equipment, and procedures for response to spills and leaks.


(ix) Any generally applicable control measures which are known to the
employer, such as appropriate engineering controls, work practices, or
personal protective equipment. 

(x) Emergency first aid procedures known to the employer. 

(xi) The date of preparation of the MSDS or of its last revision. 

(xii) The name, address, and telephone number of the individual
preparing or distributing the MSDS, or a responsible party who can
provide additional information on the substance for hazard evaluation
and any appropriate emergency procedures. 

(3) If no relevant information is found or known for any given category
on the MSDS, the employer must mark the MSDS to indicate that no
applicable information was found. 

(4) Where multiple mixtures containing the substance have similar
compositions (i.e., the chemical ingredients are essentially the same,
but the specific composition varies from mixture to mixture) and similar
hazards, the employer may prepare one MSDS to apply to all of these
multiple mixtures. 

(5) If the employer becomes aware of any significant new information
regarding the hazards of the substance or ways to protect against the
hazards, this new information must be added to the MSDS within 3 months
from the time the employer becomes aware of the new information. If the
substance is not currently being manufactured, imported, processed, or
used in the employer's workplace, the employer must add the new
information to the MSDS before the substance is reintroduced into the
workplace. 

(6) The employer must ensure that persons receiving the substance from
the employer are provided an appropriate MSDS with their initial
shipment and with the first shipment after an MSDS is revised. The
employer may either provide the MSDS with the shipped containers or send
it to the person prior to or at the time of shipment. 

(7) The employer must maintain a copy of the MSDS in its workplace, and
must ensure that it is readily accessible during each work shift to
employees when they are in their work areas. 

(8) The MSDS may be kept in any form, including as operating
procedures, and may be designed to cover groups of substances in a work
area where it may be more appropriate to address the potential hazards
of a process rather than individual substances. However, in all cases,
the required information must be provided for each substance and must be
readily accessible during each work shift to employees when they are in
their work areas. 

(9) The MSDS must be printed in English; however, the information may be
repeated in other languages. 

(d) Employee information and training. Each employer must ensure that
employees are provided with information and training on the substance
identified in subpart E of this part. This information and training must
be provided at the time of each employee's initial assignment to a work
area containing the substance and whenever the substance subject to this
section is introduced into the employee's work area for the first time. 

(1) Information provided to employees under this paragraph shall
include: 

(i) The requirements of this section. 

(ii) Any operations in the work area where the substance is present.

(i) Methods and observations that may be used to detect the presence or
release of the substance in or from an employee's work area (such as
monitoring conducted by the employer, continuous monitoring devices,
visual appearance, or odor of the substance when being released). 

(ii) The potential human health and environmental hazards of the
substance as specified in subpart E of this part. 

(iii) The measures employees can take to protect themselves and the
environment from the substance, including specific procedures the
employer has implemented to protect employees and the environment from
exposure to the substance, including appropriate work practices,
emergency procedures, personal protective equipment, engineering
controls, and other measures to control worker exposure and/or
environmental release required under subpart E of the

part, or alternative control measures which EPA has determined under
(721.30 provide substantially the same degree of protection as the
specified control measures. 

(iv) The requirements of the hazard communication program developed by
the employer under this section, including an explanation of the
labeling system and the MSDS required by this section and guidance on
obtaining and using appropriate hazard information. 

(e) Low concentrations in mixtures. If a substance identified in subpart
E of this part is present in the work area only as a mixture, an
employer is exempt from the provisions of this section if the
concentration of the substance in the mixture does not exceed a
concentration set in subpart E of this part. The exemption does not
apply if the employer has reason to believe that during intended use or
processing in the work area, the substance in the mixture may be
concentrated above the level set in subpart E of this part. 

(f) Existing hazard communication program. The employer need not take
additional actions if existing programs and procedures satisfy the
requirements of this section.

written requests to approve

monitoring procedures or alternative calculations within 90 days after
such requests are received. EPA will inform submitters of the
disposition of such requests in writing, and will explain the reasons

(721.91    Computation of estimated surface water concentrations:
Instructions. 

These instructions describe the use of the equation specified in
(721.90(a)(4) and (b)(4) to compute estimated surface water
concentrations which will result from release of a substance identified
in subpart E of this part. The equation shall be computed for each site
using the stream flow rate appropriate for the site according to
paragraph (b) of this section, and the highest number of kilograms
calculated to be released for that site on a given day according to
paragraph (a) of this section. Two variables shall be considered in
computing the equation, the number of kilograms released, and receiving
stream flow. 

(a) Number of kilograms released. (1) To calculate the number of
kilograms of substance to be released from manufacturing, processing, or
use operations, as specified in the numerator of the equation, develop a
process description diagram which describes each manufacturing,
processing, or use operation involving the substance. The process
description must include the major unit operation steps and chemical
conversions. A unit operation is a functional step in a manufacturing,
processing, or use operation where substances undergo chemical changes
and/or

changes in location, temperature, pressure, physical state, or similar
characteristics. Include steps in which the substance is formulated into
mixtures, suspensions, solutions, etc. 

(2) Indicate on each diagram the entry point of all feedstocks (e.g.,
reactants, solvents, and catalysts) used in the operation. Identify each
feedstock and specify its approximate weight regardless of whether the
process is continuous or batch. 

(3) Identify all release points from which the substance or wastes
containing the substance will be released into air, land, or water.
Indicate these release points on the diagram. Do not include accidental
releases or fugitive emissions. 

(4) For releases identified in the diagram that are destined for water,
estimate the amount of substance that will be released before the
substance enters control technology. The kilograms of substance released
may be estimated based on: 

(i) The mass balance of the operation, i.e., totaling inputs and
outputs, including wastes for each part of the process such that outputs
equal inputs. The amount released to water may be the difference between
the amount of the substance in the starting material (or formed in a
reaction) minus the amount of waste material removed from each part of
the process and not released to water and the amount of the substance in
the final product. 

(ii) Physical properties such as water solubility where a known volume
of water being discharged is assumed to contain the substance at
concentrations equal to its solubility in water. This approach is
particularly useful where the waste stream results from separation of
organic/water phases or filtration of the substance from an aqueous
stream to be discharged. 

(iii) Measurements of flow rates of the process/use stream and known
concentrations of the substance in the stream.  

(5) After releases of a substance to water are estimated for each
operation on a site, total the releases of the substance to water from
all operations at that site. The value (number of kilograms) specified
in the numerator of the equation should reflect total kilograms of
substance released to water per day from all operations at a single
site. 

(6) Use the highest expected daily release of the substance for each
site. 

(b) Receiving stream flow. (1) The receiving stream flow shall be
expressed in million liters per day (MLD). The flow rate data to be used
must be for the point of release on the water body that first receives
release of the substance whether by direct discharge from a site, or by
indirect discharge through a Publicly-Owned Treatment Works (POTW) for
each site. The flow rate reported shall be the lowest 7-day average
stream flow with a recurrence interval of 10 years (7-Q-10). If the
7-Q-10 flow rate is not available for the actual point of release, the
stream flow rate should be used from the U.S. Geological Survey (USGS)
gauging station that is nearest the point of release that is expected to
have a flow rate less than or equal to the receiving stream flow at the
point of release. 

(2) Receiving stream flow data may be available from the National
Pollutant Discharge Elimination System (NPDES) permit for the site or
the POTW releasing the substance to surface  water, from the NPDES
permit-writing authority for the site or the POTW, or from USGS
publications, such as the water-data report series. 

(3) If receiving stream flow data are not available for a stream,
either the value of 10 MLD or the daily flow of wastewater from the site
or the POTW releasing the substance must be used as an assumed minimum
stream flow. Similarly, if stream flow data are not available because
the location of the point of release of the substance to surface water
is a lake, estuary, bay, or ocean, then the flow rate to be used must be
the daily flow of wastewater from the site or the POTW 

releasing the substance to surface water. Wastewater flow data may be
available from the NPDES permit or NPDES authority for the site or the
POTW releasing the substance to water. 

                           Subpart C -- Recordkeeping Requirements 

(721.100    Applicability. 

This subpart C identifies certain additional recordkeeping requirements
applicable to manufacturers, importers, and processors of substances
identified in subpart E of this part for each specific substance. The
provisions of this subpart C apply only when referenced in subpart E of

subpart E. If the provisions in this subpart C conflict with general
provisions of subpart A of this part, the provisions of this

subpart C shall apply. 

[54 FR 31313, July 27, 1989]

(721.125    Recordkeeping requirements. 

At the time EPA adds a substance to subpart E of this part, EPA will
specify appropriate recordkeeping requirements which correspond to the
significant new use designations for the substance selected from subpart
B of this part. Each manufacturer, importer, and processor of the
substance shall maintain the records for 5 years from the date of their
creation. In addition to the records specified in (721.40, the records
whose maintenance this section requires may include the following: 

(a) Records documenting the manufacture and importation volume of the
substance and the corresponding dates of manufacture and import.  

(b) Records documenting volumes of the substance purchased in the United
States by processors of the substance, names and addresses of suppliers,
and corresponding dates of purchase. 

(c) Records documenting the names and addresses (including shipment
destination address, if different) of all persons outside the site of
manufacture, importation, or processing to whom the manufacturer,
importer, or processor directly sells or transfers the substance, the
date of each sale or transfer, and the quantity of the substance sold or
transferred on such date. 

(d) Records documenting establishment and implementation of a program
for the use of any applicable personal protective equipment required
under (721.63. 

(e) Records documenting the determinations required by ( 721.63(a)(3)
that chemical protective clothing is impervious to the substance. 

(f) Records documenting establishment and implementation of the hazard
communication program required under (721.72. 

(g) Copies of labels required under (721.72(b). 

(h) Copies of material safety data sheets required under ( 721.72(c). 

(i) Records documenting compliance with any applicable industrial,
commercial, and consumer use limitations under ( 721.80. 

(j) Records documenting compliance with any applicable disposal
requirements under (721.85, including the method of disposal, location
of disposal sites, dates of disposal, and volume of the substance
disposed. Where the estimated disposal volume is not known to or
reasonably ascertainable by the manufacturer, importer, or processor,
that person must maintain other records which demonstrate establishment
and implementation of a program that ensures compliance with any
applicable disposal requirements. 

(k) Records documenting establishment and implementation of procedures
that ensure compliance with any applicable water discharge limitations
under (721.90.

Subpart D -- Expedited Process for Issuing Significant New Use Rules for
Selected Chemical Substances and Limitation or Revocation of Selected
Significant New Use Rules 

Source: 54 FR 31314, July 27, 1989, unless otherwise noted.

 

(721.160    Notification requirements for new chemical substances
subject to section 5(e) orders. 

(a) Selection of substances. (1) In accordance with the expedited
process specified in this section, EPA will issue significant new use
notification requirements and other specific requirements for each new
chemical substance that is the subject of a final order issued under
section 5(e) of the Act, except for an order that prohibits manufacture
and import of the substance, unless EPA determines that significant new
use notification requirements are not needed for the substance. 

(2) If EPA determines that significant new use notification requirements
are not needed for a substance that is subject to a final order issued
under section 5(e) of the Act, except for an order that prohibits
manufacture or import of the substance, 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 substance under section 5(e) of the Act. EPA may also designate
additional activities as significant new uses which will be subject to
notification. Designation of additional activities as significant new
uses will be done in accordance with the criteria and procedures

under (721.170, or through a separate rulemaking proceeding.  

(2) Significant new use requirements and other specific requirements
designated under this section will be listed in subpart E of this part.
For each substance, subpart E will identify: 

(i) The chemical name. 

(ii) The activities designated as significant new uses. 

(iii) Other specific requirements applicable to the substance, including
recordkeeping requirements or any other requirements included in the
final section 5(e) order. 

(c) Procedures for issuing significant new use rules. (1) EPA will
issue significant new use rules 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) FEDERAL REGISTER documents issued to propose or establish
significant new uses under this section will contain the following: 

(i) The chemical identity of the substance or, if its specific identity
is claimed confidential, an appropriate generic chemical name and an
accession number assigned by EPA.

(iii) The CAS number, where available and not claimed confidential. 

(iv) A summary of EPA's findings under section 5(e)(1)(A) of the Act for
the final order issued under section 5(e). 

(v) Designation of the significant new uses subject to, or proposed to
be subject to, notification and any other applicable requirements. 

(vi) Any modifications of subpart A of this part applicable to the
specific substance and significant new uses.  

(vii) 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) When EPA uses the direct final
rulemaking procedure to issue a significant new use rule, it 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 chemical
substance. 

(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 the
FEDERAL REGISTER, and a proposal will be published in the proposed rule
section of the FEDERAL 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 substance to
subpart E of this part and designating the significant new uses subject
to notification. 

(4) Notice and comment rulemaking. (i) When EPA uses a notice and
comment procedure to issue a significant new use rule, 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 chemical
substance. Persons will be given 30 days to comment on whether EPA
should establish notification requirements for the substance 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 substance to subpart E of this part and designating the
significant new uses subject to notification. 

(5) Interim final rulemaking. (i) When EPA uses the interim final
rulemaking procedure to issue a significant new use rule, EPA will issue
an interim final rule in the final rule section of the FEDERAL REGISTER
following its decision to develop a significant new use rule for a
specific new chemical substance. 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)(5)(i)(B) of this section and promulgating final
significant new use notification requirements and other requirements for
the substance. 

(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 (720.102 of this chapter for any substance for which
the notice of commencement was received on or after October 10, 1989. 

(2) 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 1 year of October 10, 1989,
for any substance for which the valid notice of commencement under
(720.102 of this chapter was received before October 10, 1989. 

(3) 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. 

(721.170    Notification requirements for selected new chemical
substances that have completed

premanufacture review. 

(a) Selection of substances. In accordance with the expedited process
specified in this section, EPA may issue significant new use
notification and recordkeeping requirements for any new chemical
substance for which a premanufacture notice has been submitted under
part 720 of this chapter if EPA determines that activities other than
those described in the premanufacture notice may result in significant
changes in human exposure or environmental release levels and/or that
concern exists about the substance's health or environmental effects. 

(b) Concern criteria. EPA may determine that concern exists about a
substance's health or environmental effects if EPA makes any one of the
following findings: 

(1)(i) The substance may cause carcinogenic effects because the
substance: 

(A) Has been shown by valid test data to cause carcinogenic effects in
humans or in at least one species of laboratory animal. 

(B) Has been shown to be a possible carcinogen based on the weight of
the evidence in short-term tests indicative of the potential to cause
carcinogenic effects. 

(C) Is closely analogous, based on toxicologically relevant similarities
in molecular structure and physical properties, to another substance
that has been shown by test data to cause carcinogenic effects in humans
or in at least one species of laboratory animal, provided that if there
is more than one such analogue, the greatest weight will be given to the
relevant data for the most appropriate analogues. 

(D) Is known or can reasonably be anticipated, based on valid scientific
data or established scientific principles, to be metabolized in humans
or transformed in the environment to a substance which may have the
potential to cause carcinogenic effects under the criteria in paragraphs
(b)(1)(i) (A), (B), or (C) of this section.  

(ii) No substance may be regulated based on a finding under paragraph
(b)(1) of this section unless EPA has also made the finding under
(721.170(c)(2)(ii). 

(2) The substance has been shown by valid test data to cause acutely
toxic effects in at least one species of laboratory animal or is closely
analogous, based on toxicologically relevant similarities  in molecular
structure and physical properties, to another substance that has been
shown by valid test data to cause acutely toxic effects in at least one
species of laboratory animal, provided that if  there is more than one
such analogue, the greatest weight will be given to the relevant data
for the most appropriate analogues. 

(3) The substance may cause serious chronic effects, serious acute
effects, or developmentally toxic effects under reasonably anticipated
conditions of exposure because the substance: 

(i) Has been shown by valid test data to cause serious chronic effects,
serious acute effects, or developmentally toxic effects in humans or in
at least one species of laboratory animal at dose levels that could be
of concern under reasonably anticipated conditions of exposure. 

(ii) Is closely analogous, based on toxicologically relevant
similarities in molecular structure and physical properties, to another
chemical substance that has been shown by valid test data to cause
serious chronic effects, serious acute effects, or developmentally toxic
effects in humans or in at least one species of laboratory animal at
dose levels that could be of concern under reasonably anticipated
conditions of exposure, provided that if there is more than one such
analogue, the greatest weight will be given to the relevant data for the
most appropriate analogues. 

(iii) Is known or can reasonably be anticipated, based on valid
scientific data or established scientific principles, to be metabolized
in humans or transformed in the environment to a substance which may
have the potential to cause serious chronic effects, serious acute
effects, or developmentally toxic effects under the criteria in
paragraph (b)(3) (i) and (ii) of this section. 

(iv) Has been shown to potentially cause developmentally toxic effects
based on the weight of the evidence in short-term tests indicative of
the potential to cause developmentally toxic effects. 

(4) The substance may cause significant adverse environmental effects
under reasonably anticipated conditions of release because the
substance:  

(i) Has been shown by valid test data to cause significant adverse
environmental effects at dose levels that could be of concern under
reasonably anticipated conditions of release. 

(ii) Is closely analogous, based on toxicologically relevant
similarities in molecular structure and physical properties, to another
substance that has been shown by valid test data to cause significant
adverse environmental effects at dose levels that could be of concern
under reasonably 

anticipated conditions of release, provided that if there is more than
one such analogue, the greatest weight will be given to the relevant
data for the most appropriate analogues. 

(iii) Has been determined, based on calculations using the substance's
physical and chemical properties, to be potentially able to cause
significant adverse environmental effects at dose levels that could be
of concern under reasonably anticipated conditions of release. 

(iv) Is known or can reasonably be anticipated, based on valid
scientific data or established scientific principles, to be
environmentally transformed to a substance which may have the potential
to cause significant adverse environmental effects under the criteria in
paragraph (b)(4) (i), (ii), and (iii) of this section. 

(5) Concern exists about the health or environmental effects of one or
more impurities or byproducts of the substance because the impurity or
byproduct meets one or more of the criteria in paragraph (b) (1) through
(4) of this section and either: 

(i) The impurity or byproduct is a new chemical substance and may be
present in concentrations that could cause adverse health or
environmental effects under reasonably anticipated conditions of
exposure or release. 

(ii) Reasonably anticipated manufacture, processing, or use activities
involving the substance for  which a premanufacture notice has been
submitted may result in significantly increased human exposure to or
environmental release of the impurity or byproduct compared to exposure
or release levels resulting from existing activities involving the
impurity or byproduct. 

(c) Designation of requirements. (1) When EPA decides to establish
significant new use reporting requirements under this section, EPA may
designate as a significant new use any one or more of the activities set
forth in subpart B of this part. In addition, EPA may designate specific
recordkeeping requirements described under subpart C of this part that
are applicable to the substance. 

(2) EPA may designate as a significant new use only those activities
that (i) are different from those described in the premanufacture notice
for the substance, including any amendments, deletions, and additions of
activities to the premanufacture notice, and (ii) may be accompanied by
changes in exposure or release levels that are significant in relation
to the health or environmental concerns identified under paragraph (b)
of this section.  

(d) Procedures for issuing significant new use rules. (1) Significant
new use requirements designated under this section will be listed in
subpart E of this part. For each substance, subpart E of this part will
identify: 

(i) The chemical name. 

(ii) The activities designated as significant new uses, which may
include one or more of the activities described in paragraph (c) of this
section.

(iii) Other specific requirements applicable to the substance.

(2) When EPA determines that a substance is a candidate for a
significant new use rule under this section, it will notify the person
that submitted the premanufacture notice for the substance no later than
7 calendar days before the expiration of the notice review period under
(720.75 of this chapter. In providing this notice, EPA will describe the
health or environmental concerns identified under paragraph (b) of this
section and the activities under consideration for designation as
significant new uses. Such notice may be by telephone, but in this event
will be confirmed in writing no later than 30 days after completion of
the notice review period.

(3) FEDERAL REGISTER documents issued to propose or establish
significant new uses under this section will contain the following:

(i) The chemical identity of the substance or, if its specific identity
is claimed confidential, an appropriate generic chemical name and an
accession number assigned by EPA.

(ii) The premanufacture notice number.

(iii) The CAS number, where available and not claimed confidential.

(iv) A summary of the basis for action under this section.

(v) Designation of the significant new uses subject to, or proposed to
be subject to, notification and any other applicable requirements.

(vi) Any modifications of subpart A of this part applicable to the
specific substances and significant new uses.

(vii) 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.(4) EPA will issue significant new use rules 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. 

(i)(A) When EPA uses the direct final rulemaking procedure to issue a
significant new use rule it will issue a direct final rule in the final
rule section of the FEDERAL REGISTER following its decision to develop a
significant new use rule under this section for a specific new chemical
substance. 

(B) The FEDERAL REGISTER document will state that, unless written notice
is received by EPA within 30 days after the date of publication that
someone wishes to submit adverse or critical comments, the SNUR will be
effective 60 days from 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 after the date of publication 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 the FEDERAL REGISTER, and EPA will issue a proposed rule in
the proposed rule section of the FEDERAL REGISTER. The proposed rule
will establish a 30-day comment period. 

(C) 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 substance to
subpart E of this part and designating the significant new uses subject
to notification. 

(ii)(A) When EPA uses a notice and comment procedure to issue a
significant new use rule, EPA will issue a proposed rule in the FEDERAL
REGISTER following its decision to develop a significant new use rule
under this section for a specific new chemical substance. Persons will
be given 30 days to comment on whether EPA should establish notification
requirements for the substance under this part.  

(B) If EPA, having considered any timely comments, decides to establish
notification requirements under this section, EPA will issue a final
rule adding the substance to subpart E of this part and designating the
significant new uses subject to notification. 

(iii)(A) When EPA uses the interim final rulemaking procedure to issue a
significant new use rule, EPA will issue an interim final rule in the
final rule section of the FEDERAL REGISTER following its decision to
develop a significant new use rule for a specific new chemical
substance. The document will state EPA's reasons for using the interim
final rulemaking procedure.  

(1) The significant new use rule will take effect on the date of
publication. 

(2) Persons will be given 30 days from the date of publication to submit
comments. 

(B) An interim final rule 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 (d)(4)(iii)(A)(2) of this section and promulgating final

significant new use notification requirements and other requirements for
the substance. 

(e) Schedule for issuing significant new use rules. (1) EPA will issue a
proposed rule, an interim final rule, or a direct final rule within 270
days of receipt of the notice of commencement under (720.102 of this
chapter for any substance for which the notice of commencement was
received on or after October 10, 1989. 

(2) If EPA receives adverse or critical comments within the designated
comment period following publication of a proposed rule or an interim
final rule, EPA will either withdraw the rule or issue a final rule
addressing the comments received.

(721.185    Limitation 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 chemical
substance which has been added to subpart E of this part using the
procedures under (721.160 or (721.170. 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 substance will not present an unreasonable risk of injury to
human 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 substance
that eliminates the need for significant new use notification under
section 5(a)(2) of the Act. 

(3) EPA has received significant new use notices for some or all of the
activities designated as significant new uses of the substance and,
after reviewing such notices, 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 or analysis supporting its decision to add the
substance to subpart E of this part under (721.170 and has concluded
that the substance does not meet the criteria under (721.170(b). 

(5) For a substance added to subpart E of this part under (721.160, EPA
has examined new information, or has reexamined the test data or other
information or analysis 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 substance
may present an unreasonable risk of injury to human health or the
environment required under section 5(e)(1)(A) of the Act. 

(6) For a substance added to subpart E of this part under (721.160,
certain activities involving the substance 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 substance that
has been added to subpart E of this part using the procedures described
under (721.160 or (721.170 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 substance that has
been added to subpart E of this part using the procedures described in
(721.160 or (721.170 by writing to the Director of the Office of
Pollution Prevention and Toxics and stating the basis for such request.
All requests should be sent to the Document Control Office (7407),
Office of Pollution Prevention and Toxics, U.S. Environmental Protection
Agency, Room G-099, 1200 Pennsylvania Ave., NW., Washington, DC 20460.
ATTN: Request to amend significant new use rule. The request must be
accompanied by information sufficient to support the request. 

(2) The Director of the Office of Pollution Prevention and Toxics 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 substance should remain in effect. 

(3) If EPA concludes that significant new use notification requirements
for a substance should be limited or revoked, EPA will propose the
changes in the FEDERAL REGISTER, briefly describe the grounds for the
action, and provide interested parties an opportunity to comment.
