as appropriate, disproportionately high 

and adverse human health or 

environmental effects of their programs, 

policies, and activities on minority 

populations and low-income 

populations in the United States. 

EPA has determined that the listing 

action and the final determination will 

not have disproportionately high and 

adverse human health or environmental 

effects on minority or low-income 

populations because it increases the 

level of environmental protection to 

populations in affected ozone 

nonattainment areas without having any 

disproportionately high and adverse 

human health or environmental effects 

on any populations, including any 

minority or low-income populations. 

The purpose of section 183(e) is to 

obtain VOC emission reductions to 

assist in the attainment of the ozone 

NAAQS. The health and environmental 

risks associated with ozone were 

considered in the establishment of the 

ozone NAAQS. The level is designed to 

be protective of the public with an 

adequate margin of safety. EPA’s listing 

of the products and its determination 

that CTGs are substantially as effective 

as regulations are actions intended to 

help States achieve the NAAQS in the 

most appropriate fashion. 

K. Congressional Review Act 

The Congressional Review Act, 5 

U.S.C. 801 et seq., as added by the Small 

Business Regulatory Enforcement 

Fairness Act of 1996, generally provides 

that before a rule may take effect, the 

agency promulgating the rule must 

submit a rule report, which includes a 

copy of the rule, to each House of the 

Congress and to the Comptroller General 

of the United States. EPA will submit a 

report containing this notice and other 

required information to the U.S. Senate, 

the U.S. House of Representatives, and 

the Comptroller General of the United 

States prior to publication of the notice 

in the Federal Register. A major rule 

cannot take effect until 60 days after it 

is published in the Federal Register. 

This action is not a ‘‘major rule’’ as 

defined by 5 U.S.C. 804(2). This rule 

will be effective October 9, 2007.

Perfluoroalkyl Sulfonates; Significant 

New Use Rule 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: EPA is amending a significant 

new use rule (SNUR) under section 

5(a)(2) of the Toxic Substances Control 

Act (TSCA) to include certain additional 

perfluoroalkyl sulfonate (PFAS) 

chemicals. EPA is amending the PFAS 

SNUR at 40 CFR 721.9582 by adding a 

new Table 3 which includes the PFAS 

chemicals currently on the public TSCA 

Inventory that are not already covered 

by the SNUR. This rule requires 

manufacturers, including importers, to 

notify EPA at least 90 days before 

commencing the manufacture or import 

of the PFAS chemicals listed in Table 3 

of the regulatory text for the significant 

new uses described in this document on 

or after November 8, 2007. EPA believes 

that this action is appropriate because 

these chemical substances may be 

hazardous to human health and the 

environment. This required notice will 

provide EPA the opportunity to evaluate 

intended significant new uses and 

associated activities before they occur 

and, if necessary, to prohibit or limit 

those uses or activities. 

DATES: This final rule is effective 

November 8, 2007.

SUPPLEMENTARY INFORMATION: 

I. Does this Action Apply to Me? 

You may be potentially affected by 

this action if you manufacture or import 

any of the chemical substances that are 

listed in Table 3 of the regulatory text. 

This action may also affect certain 

entities through pre-existing import 

certification and export notification 

rules under TSCA. Persons who import 

any chemical substance governed by a 

final SNUR are subject to the TSCA 

section 13 (15 U.S.C. 2612) import 

certification requirements and the 

corresponding regulations at 19 CFR 

12.118 through 12.127 and 127.28. 

Those persons must certify that the 

shipment of the chemical substance 

complies with all applicable rules and 

orders under TSCA, including any 

SNUR requirements. The EPA policy in 

support of import certification appears 

at 40 CFR part 707, subpart B. In 

addition, any persons who export or 

intend to export a chemical substance 

that is the subject of this rule are subject 

to the export notification provisions of 

TSCA section 12(b)(15 U.S.C. 

2611(b))(see 40 CFR 721.20), and must 

comply with the export notification 

requirements in 40 CFR part 707, 

subpart D. Potentially affected entities 

may include, but are not limited to: 

• Manufacturers (defined by statute to 

include importers) or chemical 

exporters of one or more of the subject 

chemical substances (NAICS codes 325 

and 324110), e.g., chemical 

manufacturing and petroleum refineries. 

• Establishments (NAICS code 

332813), e.g., primarily engaged in 

electroplating, plating, anodizing, 

coloring, buffing, polishing, cleaning, 

and sandblasting metals and metal 

products. 

This listing is not intended to be 

exhaustive, but rather provides a guide 

for readers regarding entities likely to be 

affected by this action. Other types of 

entities not listed in this unit could also 

be affected. The North American 

Industrial Classification System 

(NAICS) codes have been provided to 

assist you and others in determining 

whether this action might apply to 

certain entities. To determine whether 

you or your business may be affected by 

this action, you should carefully 

examine the applicability provisions in 

40 CFR 721.5 and 40 CFR 721.9582 as 

described herein. Also consult Unit II. If 

you have any questions regarding the 

applicability of this action to a 

particular entity, consult the technical 

person listed under FOR FURTHER

INFORMATION CONTACT. 

II. Background 

In the Federal Register of March 10, 

2006 (71 FR 12311) (FRL–7740–6), EPA 

proposed to add 183 PFAS chemicals to 

the SNUR at 40 CFR 721.9582. The 183 

chemicals being added to the SNUR are 

listed in Table 3 in the regulatory text 

of this document. The chemicals listed 

in Table 3 are on the public TSCA 

Inventory and have the characteristic 

PFAS chemical structure of a 

perfluorinated carbon chain (Rf) greater 

than, or equal to, C5 attached to an SO2 

group connected to the rest of the 

molecule. In addition, the proposal also 

included those chemicals with Rf ranges 

of perfluorinated carbon chains shorter 

than C5, and greater than C5, for 

example, C4–C12 and C6–C12. In this 

SNUR, this PFAS chemical structure is 

referred to as the Rf moiety. EPA 

believed the action was warranted given 

the similarity of these chemicals to 

those currently included in 40 CFR 

721.9582 and the strong likelihood of 

similar health and environmental 

concerns, as discussed in Unit III. of the 

March 10, 2006 document. EPA also 

proposed to make the excepted uses 

described in 40 CFR 721.9582(a)(3) 

applicable to the chemicals listed in 

Table 3 of the proposed regulatory text. 

A. What Action is the Agency Taking? 

The Agency is designating as a 

‘‘significant new use’’ the manufacture, 

including import, of the chemical 

substances listed in Table 3 of the 

regulatory text, for any use, except for 

the excluded uses described in this unit. 

Based on comments received during the 

public comment period and related 

communications, EPA learned of an 

ongoing use of seven PFAS chemicals as 

a component of an etchant used in the 

plating process to produce electronic 

devices. Consequently, that use has 

been excluded from this SNUR for those 

seven chemicals. See § 721.9582(a)(5) or 

the discussion in this unit of the 

significant new uses for a list of those 

chemicals. 

In addition, the public comments 

described the ongoing use of PFAS 

chemicals as a fume/mist suppressant in 

metal finishing and plating baths. 

However, based on searches of the 

Internet which generated information on 

PFAS from the Organization for 

Economic Cooperation and 

Development (OECD), industry, and 

information from the California Air 

Resources Board (Refs. 1 and 2), EPA 

has concluded that only one chemical in 

Table 3, tetraethylammonium 

perfluorooctanesulfonate (CAS No. 

56773–42–3), is used in this application. 

Therefore, EPA has excluded that use of 

this chemical from this SNUR. However, 

EPA remains concerned about this use, 

because at least two commenters to this 

SNUR noted that small quantities of this 

PFAS surfactant are released in the 

routine renewal of the plating baths. In 

addition, since the close of the public 

comment period, EPA has learned from 

a 2007 survey by Minnesota of over 30 

wastewater treatment plants that PFOS, 

which is the anionic counterion of this 

PFAS surfactant, is appearing in 

wastewater treatment plant influent, 

effluent, and sludge associated with the 

fume/mist suppressant use in metal 

finishing and plating baths. As a result 

of these concerns, although outside the 

scope of this rule, EPA will continue to 

work with state agencies and industry to 

identify best management practices for 

minimizing the release of this PFAS 

surfactant. 

A chemical fume (or mist) 

suppressant refers to any chemical agent 

that reduces or suppresses fumes or 

mists at the surface of an electroplating 

bath or solution. Chemical fume 

suppressants are ‘‘surface-active’’

compounds that can be added directly 

to a chrome plate acid bath to reduce or 

control misting (Ref. 3). PFAS chemicals 

are effective fume suppressants because 

of their surfactant properties. Fume 

suppressants act by reducing the plating 

bath surface tension which then inhibits 

misting. Misting occurs when bubbles 

break free of a liquid bath’s surface and 

burst in the air. When the surface 

tension of a bath is lowered, as occurs 

with the use of PFAS fume 

suppressants, gases escape at the surface 

of the plating bath solution with less of 

a ‘‘bursting’’ effect, forming less mist 

(Ref. 4). Such fume suppressants, as 

opposed to other chemical surfactants, 

are used in the plating industry because 

the PFAS fume suppressant is able to 

withstand the harsh conditions of 

plating baths while lowering the plating 

bath surface tension to levels specified 

by current regulatory standards (Ref. 5). 

While several of these PFAS chemicals 

were developed for this use, only one is 

being used currently. 

The plating fume suppressant that 

contains tetraethylammonium 

mstockstill on PROD1PC66 with RULES

57224 Federal Register / Vol. 72, No. 194 / Tuesday, October 9, 2007 / Rules and Regulations 

perfluorooctanesulfonate (CAS No. 

56773–42–3) to reduce surface tension 

is different than the types of fume 

suppressants used in the plating 

industry that produce a foam blanket, 

and which can be used alone or in 

conjunction with PFAS fume 

suppressants. 

This rule requires persons to notify 

EPA at least 90 days before commencing 

the manufacture (including import) of 

the chemical substances identified in 

Table 3 of the regulatory text for any 

use, except: 

• Use as an anti-erosion additive in 

fire-resistant phosphate ester aviation 

hydraulic fluids. 

• Use as a component of a photoresist 

substance, including a photo acid 

generator or surfactant, or as a 

component of an anti-reflective coating, 

used in a photomicrolithography 

process to produce semiconductors or 

similar components of electronic or 

other miniaturized devices. 

• Use in coating for surface tension, 

static discharge, and adhesion control 

for analog and digital imaging films, 

papers, and printing plates, or as a 

surfactant in mixtures used to process 

imaging films. 

• Use of: 1-Pentanesulfonic acid, 

1,1,2,2,3,3,4,4,5,5,5-undecafluoro-, 

potassium salt (CAS No. 3872–25–1); 

Glycine, N-ethyl-N-

[(tridecafluorohexyl)sulfonyl]-, 

potassium salt (CAS No. 67584–53–6); 

Glycine, N-ethyl-N-

[(pentadecafluoroheptyl)sulfonyl]-, 

potassium salt (CAS No. 67584–62–7); 

1-Heptanesulfonic acid, 1,1,2,2,3,3,4,4,

5,5,6,6,7,7,7-pentadecafluoro-, 

ammonium salt (CAS No. 68259–07–4); 

1-Heptanesulfonamide, N-ethyl-1,1,

2,2,3,3,4,4,5,5,6,6,7,7,7-

pentadecafluoro- (CAS No. 68957–62–

0); Poly(oxy-1,2-ethanediyl), .alpha.-[2- 

[ethyl[(pentadecafluoroheptyl)

sulfonyl]amino]ethyl]-.omega.-methoxy- 

(CAS No. 68958–60–1); or 1-

Hexanesulfonic acid, 1,1,2,2,3,3,4,4,5,

5,6,6,6-tridecafluoro-, compd. with 2,2′- 

iminobis[ethanol] (1:1) (CAS No. 70225–

16–0) as a component of an etchant, 

including a surfactant or fume 

suppressant, used in the plating process 

to produce electronic devices. 

• Use of tetraethylammonium 

perfluorooctanesulfonate (CAS No. 

56773–42–3) as a fume/mist suppressant 

in metal finishing and plating baths. 

Examples of such metal finishing and 

plating baths include: Hard chrome 

plating; decorative chromium plating; 

chromic acid anodizing; nickel, 

cadmium, or lead plating; metal plating 

on plastics; and alkaline zinc plating. 

• Use as an intermediate only to 

produce other chemical substances to be 

used solely for the uses listed in bullets 

1, 2, or 3 of this unit. 

B. What is the Agency’s Authority for 

Taking this Action? 

Section 5(a)(2) of TSCA (15 U.S.C. 

2604(a)(2)) authorizes EPA to determine 

that a use of a chemical substance is a 

‘‘significant new use.’’ EPA must make 

this determination by rule after 

considering all relevant factors, 

including those listed in TSCA section 

5(a)(2). Once EPA determines that a use 

of a chemical substance is a significant 

new use, TSCA section 5(a)(1)(B) 

requires persons to submit a Significant 

New Use Notice (SNUN) to EPA at least 

90 days before they manufacture, 

import, or process the chemical 

substance for that use (15 U.S.C. 

2604(a)(1)(B)). The mechanism for 

reporting under this requirement is 

established under 40 CFR 721.5. 

C. Applicability of General Provisions 

General provisions for SNURs appear 

under 40 CFR part 721, subpart A. 

These provisions describe persons 

subject to the rule, recordkeeping 

requirements, exemptions to reporting 

requirements, and applicability of the 

rule to uses occurring before the 

effective date of the final rule. 

Provisions relating to user fees appear at 

40 CFR part 700. According to 40 CFR 

721.1(c), persons subject to this SNUR 

must comply with the same notice 

requirements and EPA regulatory 

procedures as submitters of 

Premanufacture Notices (PMNs) under 

TSCA section 5(a)(1)(A). In particular, 

these requirements include the 

information submission requirements of 

TSCA section 5(b) and 5(d)(1), the 

exemptions authorized by TSCA section 

5(h)(1), (h)(2), (h)(3), and (h)(5), and the 

regulations at 40 CFR part 720. Once 

EPA receives a SNUN, EPA may take 

regulatory action under TSCA section 

5(e), 5(f), 6 or 7 to control the activities 

for which it has received the SNUN. If 

EPA does not take action, EPA is 

required under TSCA section 5(g) to 

explain in the Federal Register its 

reasons for not taking action. 

Persons who export or intend to 

export a chemical substance identified 

in a proposed or final SNUR are subject 

to the export notification provisions of 

TSCA section 12(b). The regulations that 

implement TSCA section 12(b) appear at 

40 CFR part 707, subpart D. Persons 

who import a chemical substance 

identified in a final SNUR are subject to 

the TSCA section 13 import certification 

requirements, which appear at 19 CFR 

12.118 through 12.127 and 127.28. Such 

persons must certify that the shipment 

of the chemical substance complies with 

all applicable rules and orders under 

TSCA, including any SNUR 

requirements. The EPA policy in 

support of import certification appears 

at 40 CFR part 707, subpart B. 

III. Objectives and Rationale for this 

Final Rule 

A. Objectives 

Based on the considerations in Unit 

III. of the preamble to the proposed 

SNUR and in Unit III.B. and Unit IV. of 

this preamble, by issuing this SNUR, 

EPA will achieve the following 

objectives with regard to the significant 

new uses that are designated in this 

rule: 

• EPA will receive notice of any 

person’s intent to manufacture or import 

any chemical listed in Table 3 of the 

regulatory text for the described 

significant new use before that activity 

begins. 

• EPA will have an opportunity to 

review and evaluate data submitted in a 

SNUN before the notice submitter 

begins to manufacture or import any 

chemicals listed in Table 3 of the 

regulatory text for a significant new use. 

• EPA will have an opportunity to 

regulate prospective manufacturers or 

importers of any chemical listed in 

Table 3 of the regulatory text before a 

significant new use of the chemical 

substance occurs, provided that 

regulation is warranted pursuant to 

TSCA sections 5(e), 5(f), 6 or 7. 

B. Rationale 

EPA has concerns regarding adverse 

human health and environmental effects 

of PFAS. It is highly persistent in the 

environment, it tends to bioaccumulate, 

and it is toxic. In its voluntary phase-out 

of perfluorooctane sulfonate (PFOS) and 

PFOS-related products, the 3M 

Company, which had been the sole U.S. 

manufacturer of the chemicals, 

committed to stop production of all 

perfluoroalkyl sulfonic acid products 

with alkyl chain lengths of C8 or greater. 

3M completed its phase-out of PFOS 

production in 2002, which led to a 

significant reduction in the use of all 

PFAS-related substances. 

Production of the 183 PFAS 

chemicals in Table 3 is limited to the 

excluded uses described in 40 CFR 

721.9582(a)(3) and in Unit II.A. of this 

document. Production volumes and 

exposures have been decreasing. Any 

manufacture or import for a significant 

new use is expected to significantly 

increase exposures beyond levels that 

now occur. EPA is concerned that 

manufacture or import of the PFAS 

chemicals listed in Table 3 of the 

regulatory text for any uses not 

mstockstill on PROD1PC66 with RULES

Federal Register / Vol. 72, No. 194 / Tuesday, October 9, 2007 / Rules and Regulations 57225 

excluded by this SNUR could be 

reinitiated in the future. The notice 

required by this SNUR will provide EPA 

with additional information to evaluate 

activities associated with a significant 

new use and to protect against 

unreasonable risks, if any, from 

exposure to the substances. 

IV. Significant New Use Determination 

Section 5(a)(2) of TSCA states that 

EPA’s determination that a use of a 

chemical substance is a significant new 

use must be made after consideration of 

all relevant factors including: 

• The projected volume of 

manufacturing and processing of a 

chemical substance. 

• The extent to which the use 

changes the type or form of exposure of 

humans or the environment to a 

chemical substance. 

• The extent to which the use 

increases the magnitude and duration of 

exposure of human beings or the 

environment to a chemical substance. 

• The reasonably anticipated manner 

and methods of manufacturing, 

processing, distribution in commerce, 

and disposal of a chemical substance. 

TSCA section 5(a)(2) authorizes EPA 

to consider any other relevant factors in 

addition to the factors enumerated in 

the bulleted items. 

To determine what would constitute a 

significant new use of a chemical listed 

in Table 3 of the regulatory text, EPA 

considered relevant information about 

the toxicity of the PFAS substances, 

likely human exposures and 

environmental releases associated with 

possible uses, and the four factors listed 

in this unit. 

As described in Unit III. of the 

proposed SNUR, EPA has concerns 

regarding the reproductive and 

subchronic toxicity, persistence, and 

bioaccumulative potential of the 

chemical substances that are included 

in this SNUR. These concerns lead the 

Agency to believe that humans and the 

environment could suffer adverse effects 

from their use. Any use of these PFAS 

chemicals would continue to add to the 

reservoir of perfluoroalkyl sulfonic 

acids (PFASA) in the environment, 

resulting in additional human/ 

environmental exposure. There is 

evidence that PFAS-containing 

chemicals degrade to perfluoroalkyl 

sulfonic acids (PFASA), which exist in 

the anionic form in the environment, or 

to PFASA precursors. 

The latest information available to 

EPA indicates that the chemicals listed 

in Table 3 of the regulatory text are no 

longer being manufactured for any uses 

other than the excluded uses described 

in Unit II. of this SNUR. EPA believes 

that reintroduction of PFAS for any use 

other than the listed uses EPA has 

identified could significantly increase 

the production volume, and the 

magnitude and duration of exposure to 

humans and the environment to these 

chemical substances over that which 

would otherwise exist. Consequently, 

EPA wants the opportunity to evaluate 

and control, if appropriate, exposures 

associated with those activities before 

they occur. Based upon the relevant 

factors discussed in this unit, EPA has 

determined that the manufacture, 

including import, of any of the 

chemicals listed in Table 3 of the 

regulatory text for any use other than 

those described in Unit II., is a 

significant new use. 

EPA will continue to evaluate the 

excluded uses and may pursue 

additional regulatory action under 

TSCA, if necessary in the future. 

V. Test Data and Other Information 

TSCA section 5 does not require the 

development of any particular test data 

before submission of a SNUN. Persons 

are required to submit only test data in 

their possession or under their control 

and to describe any other data known to 

or reasonably ascertainable by them (15 

U.S.C. 2604(d); 40 CFR 721.25). 

In view of the Agency’s concerns 

regarding activities associated with the 

significant new use(s) of any chemical 

listed in Table 3 of the regulatory text, 

EPA recommends that SNUN submitters 

include data that would permit a 

reasoned evaluation of risks posed by 

the chemical substance during its 

manufacture, import, processing, use, 

distribution in commerce, or disposal. 

EPA encourages persons to consult with 

the Agency before submitting a SNUN. 

As part of this optional pre-notice 

consultation, EPA would discuss 

specific data it believes may be useful 

in evaluating a significant new use. 

SNUNs submitted for significant new 

uses without any test data may increase 

the likelihood that EPA will take action 

under TSCA section 5(e) to prohibit or 

limit activities associated with the 

chemical. 

SNUN submitters should be aware 

that EPA will be better able to evaluate 

SNUNs that provide detailed 

information on: 

• Human exposures and 

environmental releases that may result 

from the significant new uses of the 

chemical substance. 

• Potential benefits of the chemical 

substance. 

• Information on risks posed by the 

chemical substance compared to risks 

posed by potential substitutes. 

VI. SNUN Submissions 

SNUNs must be mailed to the 

Environmental Protection Agency, 

OPPT Document Control Office 

(7407M), 1200 Pennsylvania Ave., NW., 

Washington, DC 20460–0001. 

Information must be submitted in the 

form and manner set forth in EPA Form 

No. 7710–25. This form is available 

from the Environmental Assistance 

Division (7408M), 1200 Pennsylvania 

Ave., NW., Washington, DC 20460–0001 

(see 40 CFR 721.25 and 720.40). Forms 

and information are also available 

electronically at http://www.epa.gov/ 

opptintr/newchems/pubs/ 

pmnforms.htm. 

As discussed in Unit V., EPA 

recommends that submitters consult 

with the Agency prior to submitting a 

SNUN to discuss what data may be 

useful in evaluating a significant new 

use. Discussions with the Agency prior 

to submission can afford submitters 

ample time to conduct any tests that 

might be helpful in evaluating the risks 

posed by the substance. 

VII. Applicability of Rule to Uses 

Occurring Before Effective Date of the 

Final Rule 

As discussed in the Federal Register 

of April 24, 1990 (55 FR 17376), EPA 

has decided that the intent of section 

5(a)(1)(B) of TSCA is best served by 

designating a use as a significant new 

use as of the date of publication of the 

proposed rule rather than as of the 

effective date of the final rule. If uses 

begun after publication of the proposed 

rule were considered ongoing rather 

than new, it would be difficult for EPA 

to establish SNUR notice requirements, 

because a person could defeat the SNUR 

by initiating the proposed significant 

new use before the rule became final, 

and then argue that the use was ongoing 

as of the effective date of the final rule. 

Thus, persons who may have begun 

commercial manufacture or import of 

the chemical substances listed in Table 

3 of the regulatory text for the 

significant new uses listed in this final 

SNUR after the proposal was published 

on March 10, 2006, must stop that 

activity before the effective date of this 

final rule. To resume their activities, 

these persons would have to comply 

with all applicable SNUR notice 

requirements and wait until the notice 

review period, including all extensions, 

expires. EPA has promulgated 

provisions to allow persons to comply 

with this SNUR before the effective 

date. If a person were to meet the 

conditions of advance compliance 

under § 721.45(h), that person would be 

considered to have met the 

mstockstill on PROD1PC66 with RULES

57226 Federal Register / Vol. 72, No. 194 / Tuesday, October 9, 2007 / Rules and Regulations 

requirements of the final SNUR for 

those activities. 

VIII. Discussion of the Final Significant 

New Use Rule and Response to 

Comments 

This action finalizes the SNUR 

proposed in the Federal Register on 

March 10, 2006 (71 FR 12311). On April 

10, 2006 (71 FR 18055) (FRL–7779–7), 

EPA extended the closing date of the 

public comment period from April 10, 

2006 to May 10, 2006. On May 10, 2006 

(71 FR 27217) (FRL–8068–8), EPA 

further extended the closing date of the 

comment period from May 10, 2006 to 

August 8, 2006. 

This final rule requires persons who 

intend to manufacture or import any of 

the chemical substances listed in Table 

3 of the regulatory text for any use other 

than those excluded uses described in 

Unit II.A. to submit a SNUN at least 90 

days before commencing the 

manufacture or importation of any of 

these chemicals. 

It should be noted that, in Table 3, 

some of the chemical names are 

different from those in the previous 

proposed SNUR of March 10, 2006. This 

is due to enhancement of the 

nomenclature or nomenclature changes 

adopted by the Chemical Abstracts 

Service (CAS). CAS is now using the 

16th Collective Index (known as the 

ACI). EPA has updated the previously 

used 9th Collective Index names to 

reflect the latest changes by CAS. The 

CAS numbers and chemicals, however, 

remain the same. In some cases, the 

extremely long ACI names have been 

truncated to save space. Each complete 

ACI name is available at the EPA 

website in the TSCA Substance Registry 

System (SRS) at http://www.epa.gov/srs. 

Also, to be consistent with the other 

tables already in the SNUR, the order of 

the listing has been reversed from the 

descending order used in the proposed 

SNUR to ascending order used in this 

final SNUR. 

The Agency reviewed and considered 

all comments received related to the 

proposed rule. Copies of all non-CBI 

comments are available at http:// 

www.regulations.gov in the public 

docket for this action, EPA–HQ–OPPT–

2005–0015. A discussion of the 

comments germane to the rulemaking, 

and the Agency’s responses, follows. 

1. Comment summary. Metal plating 

and finishing industries that currently 

use specific PFAS chemicals to meet 

regulatory standards for hexavalent 

chromium (Cr(VI)) emissions 

established by Federal and State 

regulations need to be excluded from 

the SNUR as a current use (similar to 

the exclusions for semiconductors and 

imaging products in previously 

promulgated SNURs). The releases and 

exposures to PFAS associated with the 

industry are comparably of much less 

concern than those related to nickel (Ni) 

and hexavalent chromium (Cr(VI)) 

which result when PFAS fume 

suppressants are not used. In addition, 

the economic and competitive liabilities 

will cripple this domestic industry if 

these chemicals are no longer permitted 

to be used. Commenters described their 

continuing efforts to find greener, safer 

substitutes, but explained that for many 

uses there are no viable alternatives. 

Commenters said that the metal 

finishing industry continues to support 

research and development efforts to 

identify commercially viable 

alternatives to hexavalent chromium 

plating chemistries. To date, alternative 

technologies show some promise for 

niche applications, but have not gained 

widespread commercial application due 

to: 1) The superior coating performance 

in decorative, functional, and corrosion 

protection applications for hexavalent 

chromium plating; 2) cost effective 

applications; 3) broad and flexible 

ranges of use; and 4) strong customer/ 

market preferences for hexavalent 

chromium plating. 

Response. EPA now recognizes that 

the metal plating and finishing 

industries currently use a specific PFAS 

chemical, tetraethylammonium 

perfluorooctanesulfonate (CAS No. 

56773–42–3), to meet regulatory 

standards for hexavalent chromium 

(Cr(VI)) emissions. Thus, EPA has 

included this ongoing use of 

tetraethylammonium 

perfluorooctanesulfonate, as described 

in Unit II.A., as an exclusion in this 

SNUR, but encourages the continued 

exploration for possible substitutes. 

2. Comment summary. Several 

specific uses of PFAS chemicals within 

the semiconductor, integrated circuit, 

and microelectronics industries were 

excluded from the previous two PFAS 

SNURs. The proposed SNUR includes 

an additional 183 chemicals that would 

affect those same uses in the same 

industry sectors, so the exclusions in 

the previous two SNURs should apply 

to the 183 chemicals listed in this 

SNUR. Also, these uses constitute 

ongoing uses, not significant new uses. 

The semiconductor industry has 

supported reduction initiatives and 

dialogue through trade associations in 

other regions around the world. One 

primary locus for reduction initiatives 

and dialogue has been the World 

Semiconductor Council. 

Response. EPA recognizes that these 

are ongoing uses, and is therefore not 

designating the uses as significant new 

uses of the chemicals listed in Table 3. 

EPA is applying the exclusions 

described in Unit II.A. to the list of 183 

PFAS chemicals in Table 3 of the 

regulatory text. EPA appreciates the 

efforts the semiconductor, integrated 

circuit, and microelectronics industries 

have made in their commitment to limit 

PFAS usage, to search for alternatives, 

and to limit exposures and releases. 

3. Comment summary. Several 

specific uses of PFAS chemicals within 

the photographic film, paper, and 

imaging industries were excluded from 

the previous two PFAS SNURs. The 

proposed SNUR targets a broader list of 

183 chemicals for these applications in 

the same industry sector. The exclusion 

in the previous SNURs should be 

applied to the 183 chemicals as well. 

Also, these uses constitute ongoing uses, 

not significant new uses. Comments also 

stated that since concerns were first 

raised in 2000, the photographic film, 

paper, and imaging industries have 

aggressively pursued a voluntary risk 

reduction strategy by investing heavily 

in research to find alternative 

substances that possess the performance 

features described earlier for PFAS. 

Response. EPA recognizes that these 

are ongoing uses, and is therefore not 

designating the uses as significant new 

uses of the chemicals listed in Table 3. 

EPA is applying the current exclusion 

described in Unit II.A. to the list of 183 

PFAS chemicals in Table 3 of the 

regulatory text. EPA appreciates the 

efforts the photographic film, paper, and 

imaging industries have made in their 

commitment to limit PFAS usage, to 

search for alternatives, and to limit 

exposures and releases. 

4. Comment summary. Commenter 

requested an explanation of how the 183 

chemicals in this SNUR were chosen, 

and pointed out that some of the alkyl 

ranges covered by the SNUR include 

chemicals with the PFAS chemical 

structure (Rf moiety) with a C4 chain 

length. 

Response. EPA proposed that any 

PFAS chemical listed on the public 

TSCA Inventory that contained the Rf 

moiety with a chain length of C5 or 

larger as part of the chemical identity 

would be subject to the rulemaking 

process for this PFAS SNUR based on 

the similarity of these chemicals to 

those currently included in 40 CFR 

721.9582. That decision addresses all 

PFAS chemicals on the public inventory 

that still remain after the previous two 

SNURs and the evidence that 

manufacturers have been moving to use 

the lower chain length PFAS chemicals. 

EPA also included all ranges that 

contained > C4 constituents, even when 

that lower end of the alkyl chain length 

mstockstill on PROD1PC66 with RULES

Federal Register / Vol. 72, No. 194 / Tuesday, October 9, 2007 / Rules and Regulations 57227 

included C4 composition, in order to 

capture the higher homologues, 

including C8, as discussed in the 

proposed rule. 

5. Comment summary. This comment 

summary is based on the sanitized 

version of a Confidential Business 

Information (CBI) comment submitted to 

docket ID number EPA–HQ–OPPT–

2005–0015, DCN # 63070000019, as 

well as additional information later 

provided by the commenter. The 

commenter originally indicated that it 

uses 13 of the 183 chemicals in/as 

various specified applications. The 

commenter stated: 1) PFAS substances 

are not directly or indirectly introduced 

into consumer products; 2) the 

exclusions should be applied to the 183 

chemicals in Table 3 of the proposed 

SNUR; and 3) it uses these chemicals for 

a specific use that is different from those 

uses that were excluded in previous 

SNURs, i.e., as a component of an 

etchant, including a surfactant or fume 

suppressant, used in the plating process 

to produce electronic devices. The 

commenter also provided information 

for the low risk applications of PFAS in 

these uses; e.g., low volume, low 

exposure to workers, and low PFAS 

content, and product stewardship 

accomplishments. The commenter 

requested an exclusion based on the 

activities being ongoing for use as a 

component of an etchant, including a 

surfactant or mist/fume suppressant, in 

plating processes to produce electronic 

devices. The commenter also reduced 

the number of chemicals involved in 

this ongoing etchant use from thirteen to 

seven chemicals. 

Response. The Agency now 

recognizes the use of the seven 

chemicals identified by the commenter 

as a component of an etchant used in 

the plating process to produce 

electronic devices is an ongoing use. 

Consequently, the Agency has included 

this use of any of the seven chemicals 

as an exclusion in the final SNUR. 

IX. Economic Analysis 

A. SNUNs 

EPA evaluated the potential costs of 

establishing SNUR reporting 

requirements for potential 

manufacturers and importers of the 

chemical substances included in Table 

3 of the regulatory text. While most 

businesses are subject to a $2,500 user 

fee required by 40 CFR 700.45(b)(2)(iii), 

small businesses with annual sales of 

less than $40 million when combined 

with those of the parent company (if 

any) are subject to a reduced user fee of 

$100 (40 CFR 700.45(b)(1)). The cost of 

submitting a SNUN, estimated in EPA’s 

Economic Analysis at $7,991, including 

the user fee (Ref. 6), will be incurred 

only if a company decides to pursue a 

significant new use as defined in this 

final SNUR. Furthermore, while the 

expense of a SNUN and the 

uncertainties of possible EPA regulation 

may discourage certain innovations, that 

impact would be limited because such 

factors are unlikely to discourage an 

innovation that has high potential value. 

EPA’s complete economic analysis is 

available in the public docket for this 

rule (See docket ID number EPA–HQ–

OPPT–2005–0015). 

B. Export Notification 

Under section 12(b) of TSCA and 

implementing regulations at 40 CFR part 

707, subpart D, exporters must notify 

EPA if they export or intend to export 

a chemical substance or mixture for 

which, among other things, a rule has 

been proposed or promulgated under 

TSCA section 5. On November 14, 2006, 

EPA revised the export notification 

requirement from an annual to a onetime requirement per each destination 

country for each exporter of a chemical 

substance subject to TSCA sections 

5(a)(2), 5(b), 5(e)(1), and 5(e)(2) 

(November 14, 2006, 71 FR 66234) 

(FRL–8101–3). Previous to this 

amendment, exporters were required to 

submit a notice the first time in the 

calendar year they exported a particular 

chemical to a particular country. 

Notifications must include the 

exporter’s name and address, the 

chemical name, the date(s) of export or 

intended export, the importing country 

(or countries), and the section of TSCA 

under which EPA has taken action. The 

total costs of export notification will 

vary by chemical, depending on the 

number of required notifications (i.e., 

the number of countries to which the 

chemical is exported). 

In the report, Final Economic 

Analysis of the Amendments to TSCA 

Section 12(b) Export Notification 

Requirements (Ref. 7), it estimated the 

one-time export notification cost for an 

exporter making 25 submissions in a 

year to be $1,076. For a single 

notification, the cost would be $43.04 

($1,076/25). This supersedes an earlier 

1992 EPA estimate that the one-time 

cost of preparing and submitting an 

export notification was $62.60, and the 

subsequent update of that figure for 

inflation which was included in the 

economic analysis for the proposed 

SNUR. 

The total costs of export notification 

will vary per chemical, depending on 

the number of required notifications 

(i.e., number of countries to which the 

chemical is exported). EPA is unable to 

make any estimate of the likely number 

of export notifications for chemicals 

covered in this SNUR.

XI. Statutory and Executive Order 

Reviews 

A. Executive Order 12866 

Under Executive Order 12866, 

entitled Regulatory Planning and 

Review (58 FR 51735, October 4, 1993), 

the Office of Management and Budget 

(OMB) has determined that this SNUR 

is not a ‘‘significant regulatory action’’

subject to review by OMB, because it 

does not meet the criteria in section 3(f) 

of the Executive Order. 

B. Paperwork Reduction Act 

According to the Paperwork 

Reduction Act (PRA), 44 U.S.C. 3501 et 

seq., an Agency may not conduct or 

sponsor, and a person is not required to 

respond to a collection of information 

that requires OMB approval under the 

PRA, unless it has been approved by 

OMB and displays a currently valid 

OMB control number. The OMB control 

numbers for EPA’s regulations codified 

mstockstill on PROD1PC66 with RULES

57228 Federal Register / Vol. 72, No. 194 / Tuesday, October 9, 2007 / Rules and Regulations 

in chapter 40 of the CFR, after appearing 

in the preamble of the final rule, are 

listed in 40 CFR part 9, are displayed 

either by publication in the Federal 

Register or by other appropriate means, 

such as on the related collection 

instrument or form, if applicable. The 

display of OMB control numbers in 

certain EPA regulations is consolidated 

in 40 CFR part 9. For the ICR activity 

contained in this final rule, in addition 

to displaying the applicable OMB 

control number in this unit, the OMB 

control number assigned to this ICR 

activity is already included in the table 

in 40 CFR 9.1. 

The information collection 

requirements related to this action have 

already been approved by OMB 

pursuant to the PRA under OMB control 

number 2070–0038 (EPA ICR No. 1188). 

This action does not impose any burden 

requiring additional OMB approval. The 

burden for submitting a SNUN is 

estimated to average 107 hours per 

submission, at an estimated cost of 

$5,491. This burden estimate includes 

the time needed to review instructions, 

search existing data sources, gather and 

maintain the data needed, and 

complete, review, and submit the 

required SNUN. This burden estimate 

does not include the $2,500 user fee for 

submission of a SNUN ($100 for 

businesses with less than $40 million in 

annual sales). 

Send any comments about the 

accuracy of the burden estimate, and 

any suggested methods for minimizing 

respondent burden, including through 

the use of automated collection 

techniques, to the Director, Collection 

Strategies Division, Office of 

Environmental Information (2822T), 

Environmental Protection Agency, 1200 

Pennsylvania Ave., NW., Washington, 

DC 20460–0001. Please remember to 

include the OMB control number in any 

correspondence, but do not submit any 

completed forms to this address. 

C. Regulatory Flexibility Act 

Pursuant to section 605(b) of the 

Regulatory Flexibility Act (RFA) (5 

U.S.C. 601 et seq.), the Agency hereby 

certifies that promulgation of this SNUR 

would not have a significant adverse 

economic impact on a substantial 

number of small entities. The factual 

basis for the Agency’s determination is 

presented in the small entity impact 

analysis prepared as part of the 

economic analysis for this rule (Ref. 6), 

which is summarized in Unit IX., and a 

copy of which is available in the docket 

for this rulemaking. The following is a 

brief summary of the factual basis for 

this certification. 

Under the RFA, small entities include 

small businesses, small organizations, 

and small governmental jurisdictions. 

For purposes of assessing the impacts of 

today’s rule on small entities, small 

entity is defined in accordance with the 

RFA as: (1) A small business as defined 

by the Small Business Administration’s 

(SBA) regulations at 13 CFR 121.201; (2) 

a small governmental jurisdiction that is 

a government of a city, county, town, 

school district, or special district with a 

population of less than 50,000; and (3) 

a small organization that is any not-forprofit enterprise which is independently 

owned and operated and is not 

dominant in its field. 

A SNUR applies to any person 

(including small or large entities) who 

intends to engage in any activity 

described in the rule as a ‘‘significant 

new use.’’ By definition of the word 

‘‘new,’’ and based on all information 

currently available to EPA, it appears 

that no small or large entities presently 

engage in such activity. Because a SNUR 

requires only that any person who 

intends to engage in such activity in the 

future first notify EPA by submitting a 

SNUN, no economic impact would even 

occur until someone decides to engage 

in those activities. Although some small 

entities may decide to conduct such 

activities in the future, EPA cannot 

presently determine how many, if any, 

there may be. 

However, EPA’s experience to date is 

that, in response to the promulgation of 

over 1,000 SNURs, the Agency receives 

on average only 10 SNUNs per year. Of 

those SNUNs submitted, none appear to 

be from small entities in response to any 

SNUR. In addition, the estimated 

reporting cost for submission of a SNUN 

(see Unit IX.), is minimal regardless of 

the size of the entity. Therefore, EPA 

believes that the potential economic 

impact of complying with this SNUR is 

not expected to be significant nor 

adversely impact a substantial number 

of small entities. In a SNUR that 

published on June 2, 1997 (62 FR 29684) 

(FRL–5597–1), the Agency presented its 

general determination that proposed 

and final SNURs are not expected to 

have a significant economic impact on 

a substantial number of small entities, 

which was provided to the Chief 

Counsel for Advocacy of the Small 

Business Administration. 

D. Unfunded Mandates Reform Act 

Based on EPA’s experience with 

proposing and finalizing SNURs, State, 

local, and Tribal governments have not 

been impacted by these rulemakings, 

and EPA does not have any reason to 

believe that any State, local, or Tribal 

government would be impacted by this 

rulemaking. As such, EPA has 

determined that this regulatory action 

would not impose any enforceable duty, 

contain any unfunded mandate, or 

otherwise have any affect on small 

governments subject to the requirements 

of sections 202, 203, 204, or 205 of the 

Unfunded Mandates Reform Act of 1995 

(UMRA) (Public Law 104–4). 

E. Executive Order 13132 

This action would not have a 

substantial direct effect on States, on the 

relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government, as specified in 

Executive Order 13132, entitled 

Federalism (64 FR 43255, August 10, 

1999). 

F. Executive Order 13175 

This rule would not have Tribal 

implications because it is not expected 

to have substantial direct effects on 

Indian Tribes. This rule would not 

significantly or uniquely affect the 

communities of Indian Tribal 

governments, nor would it involve or 

impose any requirements that affect 

Indian Tribes. Accordingly, the 

requirements of Executive Order 13175, 

entitled Consultation and Coordination 

with Indian Tribal Governments (65 FR 

67249, November 6, 2000), do not apply 

to this rule. 

G. Executive Order 13045 

This action is not subject to Executive 

Order 13045, entitled Protection of 

Children from Environmental Health 

Risks and Safety Risks (62 FR 19885, 

April 23, 1997), because this is not an 

economically significant regulatory 

action as defined by Executive Order 

12866, and this action does not address 

environmental health or safety risks 

disproportionately affecting children. 

H. Executive Order 13211 

This rule is not subject to Executive 

Order 13211, entitled Actions 

Concerning Regulations That 

Significantly Affect Energy Supply, 

Distribution, or Use (66 FR 28355, May 

22, 2001), because this action is not 

expected to affect energy supply, 

distribution, or use. 

I. National Technology Transfer and 

Advancement Act 

In addition, since this action does not 

involve any technical standards, section 

12(d) of the National Technology 

Transfer and Advancement Act of 1995 

(NTTAA), Public Law 104–113, section 

12(d) (15 U.S.C. 272 note), does not 

apply to this action.

Federal Register / Vol. 72, No. 194 / Tuesday, October 9, 2007 / Rules and Regulations 57229 

J. Executive Order 12898 

This action does not entail special 

considerations of environmental justice 

related issues as delineated by 

Executive Order 12898, entitled Federal 

Actions to Address Environmental 

Justice in Minority Populations and 

Low-Income Populations (59 FR 7629, 

February 16, 1994). 

XII. Congressional Review Act 

The Congressional Review Act, 5 

U.S.C. 801 et seq., generally provides 

that before a rule may take effect, the 

Agency promulgating the rule must 

submit a rule report to each House of 

the Congress and the Comptroller 

General of the United States. EPA will 

submit a report containing this rule and 

other required information to the U.S. 

Senate, the U.S. House of 

Representatives, and the Comptroller 

General of the United States prior to 

publication of the rule in the Federal 

Register. This rule is not a ‘‘major rule’’

as defined by 5 U.S.C. 804(2).
