### Executive Summary The U.S. Environmental Protection Agency (EPA) is amending a significant new use rule (SNUR) for perfluoroalkyl sulfonate (PFAS) chemical substances 1 to add PFAS chemical substances that have completed the TSCA new chemical review process but have not yet commenced production or import, and to designate processing as a “significant new use.” EPA is also adding a SNUR for long chain perfluoroalkyl carboxylate (LCPFAC) chemical substances that will designate manufacturing (including importing) or processing for use as part of carpets or for treating carpet as a significant new use , except for use of two chemical substances in carpet cleaning solution . For this SNUR, EPA is also making the article exemption inapplicable to the importation of LCPFAC chemical substances as part of carpets. This report estimates the costs of the Signific ant New Use Rule (SNUR) . Since the manufacture (including import) and processing of PFAS and LCPFAC chemical substances for the significant new uses have been discontinued, EPA expects their presence in humans and the environment to decline over time as ha s been observed in the past when production and use of other persistent chemicals has ceased. Persons subject to these SNURs will be required to notify EPA at least 90 days before commencing any significant new use. The required notifications will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit t hat activity before it occurs. A significant new use is defined as: 1) the manufacture (including import) or processing of any of the PFAS chemical substances subject to this final rule, for any use except ongoing uses specified in the 2007 PFAS Chemical Substances SNUR at § 721.9582(a)(3) through (a)(5) and 2) the manufacture (including import), processing, or import as part of carpet, of any of the LCPFAC chemical substances subject to this final rule for use as par t of carpet or to treat carpets , except for use of two chemical substances in carpet cleaning solution . A firm intending to engage in these activiti es will be required to submit a Significant New Use Notice (SNUN), incurring an estimated submission cost of $8,589 for large businesses per chemical 2 , and potentially other minor costs. The required notification will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prevent or limit potentially adverse effects from chemical use before it occurs. In addition to any firms that may make a SNUN submission, the final SNUR may also affect firms that do not make a submission. By avoiding a significant new use, a firm can avoid submission and testing costs but may incur other compliance costs. The firm may also incur “hidden” costs; for example, it could forego profitable opportunities to use the chemical in an application that would be a significant new use, or limit production volume to avoid a significant new use. Costs in this report are estimated at the firm level and reflect the burden of a SNUR on the firms that make a submission. The potential hidden costs to the firms that do not make a submission are not quantified. EPA receives only a handful of SNUNs per year. The number of firms affected by not

## 1. **Introduction** This report presents the estimated costs of the final Significant New Use Rule (SNUR) for specific perfluoroalkyl sulfonates chemicals (PFAS) and for long - chain p erfluoroalkyl c arboxylate chemicals ( LCPFACs ) used in carpet treatments . EPA is amending a SNUR at 40 CFR § 721.9582 for PFAS chemical substances to add PFAS chemical substances that have completed the TSCA new chemical review process but have not yet commenced production or import, and to designate (for all listed PFAS chemical substances) processing as a “significant new use.” EPA is also adding a SNUR for LCPFAC chemical substances that will designate manufacturing ( including importing) or processing for use as part of carpets or for treating carpet (e.g., for use in the carpet aftercare market) as a “ significant new use , ” except for use of two chemical substances in carpet cleaning solution . For this SNUR, EPA is also making the article exemption at § 721.45(f) inapplicable to persons who import LCPFAC chemical substances as part of carpets. The article exemption at § 721.45(f) remains in effect for persons who import or process LCPFAC chemical substances as part of other sorts of articles . The article exemption at § 721.45(f) relating to persons who process chemical substances as part of an article will also remain in effect, for both the PFAS SNUR and the LCPFAC SNUR . Persons subject to these SNURs will be required to notify EPA at least 90 days before commencing any significant new use. The required notifications will provide EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs. 

### PFAS Chemical Substances In this final SNUR, the term PFAS refers to a general category of perfluorinated sulfonate chemical substances of any chain length. The PFAS chemical substances for which EPA is modifying an existing SNUR are currently listed in the 2007 SNUR at § 721.9582. The PFAS chemical substances that EPA is adding to the existing SNUR will be added to this list. See 2.1.1 for the list of additional chemicals. All o f these chemical substances are referred collectively in this final rule as perfluoroalkyl sulfonates, or PFAS chemical substances. The final SNUR requires manufacturers (including importers ) or processors of PFAS chemical substances to notify EPA at least 90 days prior to the occurrence of any significant new use. A significant new use is defined as : the manufacture ( including import) or processing of any of the PFAS chemical substances subject to this final rule, for any use except ongoing uses specified in the 2007 PFAS Chemical Substances SNUR at § 721.9582(a)(3) through (a)(5) . 

### LCPFAC Chemical Substances The term LCPFAC refers to the long - chain category of perfluorinated carboxylate chemical substances with perfluorinated carbon chain lengths equal to or greater than seven carbons and equal to or less than 20 carbons . The category of LCPFAC chemical substances also includes the salts and precursors of these perfluorinated carboxylates . The perfluorinated carbon chain length upper limit means fluoropolymer s are not within the scope of this rule. However, it is important to note that any LCPFAC chemical substance that is intentionally used during fluoropolymer formulation, such as an emulsion stabilizer in aqueous dispersions, is subject to reporting for any significant new use. For example, ammonium perfluorooctanoate (APFO)

– when used as an aqueous dispersion agent in**SNUR EA for PFAS**  **and L**  **ong Chain PFAC**  **in Carpets Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  **1 -** **2** fluoropolymer production

– is subject to this SNUR if the final fluoropolymer product is used as part of carpets or to treat carpets. (Se e section 2.1.2 for further details) . The final SNUR requires manufacturers (including importers ) or processors of LCPF ACs for use in carpet treatments to notify EPA at least 90 days prior to the occurrence of any significant new use. A significant new use is defined as ; the manufacture (including import) or processing, or import as part of carpet, of any of the LCPFAC chemical substances subject to this final rule for use as part of carpet or to treat carpets , except for use of two chemical substances in carpet cleaning solution . 

### 1.1 **Statutory Au**  **thority** 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 SNUN to EPA at least 90 days before manufacturing (including importing) or processing the chemical substance for that use (15 U.S.C. 2604(a)(1)(B)). The general SNUR provisions are found at 40 CFR Part 721, Subpart A. 

### 1.2 **Summary**

**of Methodology** This analysis quantifies, to the extent possible, the costs of the final rule to society by identifying the costs to industry associated with performing the required repor ting and recordkeeping activities , and the costs to EPA of administering the rule. Industry costs consist of rule familiarization; registration with the Central Data Exchange (CDX) electronic reporting tool; collection, compilation, and submission of required information for significant new uses of the subject chemicals; export notification; and recordkeeping. Agency costs include reviewing and processing the data received as a result of the rule. Data sources for this analysis include burden estimates derived from previous information collection requests and economic analyses for related rules, compensation data acquired from government publications, and supplementary market research . In addition to estimated costs, this report qualitatively discusses the b enefits of the final rule based on the value of the information it will provide. 

### 1.3 **Organization of this Report** The remainder of this report presents EPA’s economic analysis in support of the final rule. A description of the PFAS chemicals affected by this SNUR as well as the LCPFACs and their use in carpet treatments is provided in Chapter 2 . Chapter **Error! Reference source not found.** contains estimates of the industry costs to comply with the final rule, and Chapter 4 shows estimates of the government costs associated with the administration of the final rule. Chapter 5 addresses the benefits of the final rule. Several additional impact analyses are presented in Chapter 6 , including: small entity impact analysis, as mandated by the Regulatory Flexibility Act (RFA); a burden hour analysis that responds to the requirements of the Paperwork Reduction Act (PRA); an analysis of unfunded mandates that pertains to the Unfunded Mandates Reform Act (UMRA); an analysis of environmental justice implications that addresses the requirements of Executive Order 12898; and an analysis of children’s health pertinent to Executive Order 13045.**SNUR EA for PFAS**  **and L**  **ong Chain PFAC**  **in Carpets Contract #**  **EP -** **W -** **08 -**  **010**

## 2. **Chemical Uses and Manufacturers 2.1**  **Chemicals Subject to the Final**  **Rule 2.1.1**  **PF AS**  **Chemical Substances** This SNUR applies to PFAS chemical substances, a general category of perfluorinated sulfonate chemical substances of any chain length. EPA is amending a SNUR at § 721.9582 for PFAS chemical substances to add PFAS chemical substances that have completed the TSCA new chemical review process but have not yet commenced production or import, and to designate (for all listed PFAS chemical substances) processing as a significant new use. Exhibit 2 - 1 presents seven PMN case numbers and the generic chemical names of the PFAS chemical substances being added to the list of 183 PFAS chemicals (listed in the SNUR at § 721.9582) .

Given the structural similarity of these chemicals to the PFAS chemicals covered under 40 CF R 721.9582, EPA believes that action on these PFAS chemicals is warranted. PFAS chemicals were used in a wide variety of industrial, commercial, and consumer applications , including use in firefighting foams, mining and oil well surfactants, acid mist suppressants for metal plating and electronic etching baths, alkaline cleaners, floor polishes, inks, photographic film, denture cleaners, shampoos, chemical intermediates, coating additives, carpet spot cleaners, and as an insecticide in bait stations for ant s ( EPA, 2007 e ). The chemicals of the PFAS group are virtually indestructible and have been shown to b e globally distributed and some are bioaccumulative (Nordic Screening, no date). PFAS related residues are highly toxic, persistent chemicals that pervasively found in human blood and wildlife all over the world and there is concern that these chemicals may never degrade in the environment (Kallenborn, et al. 2004). **2.1.2 LCPF**  **AC Chemical Substances** This SNUR applies to LCPF ACs used as part of carpets or to treat carpets. PF ACs are substances with special properties that have a variety of industrial applications. PF ACs are used widely in the textile industry because of their thermo - stability, ability to adapt to a variety of surface characteristics, high chemical stability, and other characteristics . 3 Specifically, LCPFAC chemical

This category definition of LCPFAC, based on the chemical structures above, refers to a large group of chemical substances containing perfluorooctanoic acid (PFOA) and its higher homologues. The category also includes the salts and precursors of these chemical substances. LCPFAC precursors may be simple derivatives of PFOA and higher homologues or polymers that may degrade to PFOA or hi gher homologues. These precursors include all fluorotelomer s. The LCPFAC category definition has an upper limit of 20 perfluorinated carbons, which means fluoropolymers are not within the scope of this rule . However, it is important to note that any LCPFAC chemical substance that is intentionally used during fluoropolymer formulation, such as an emulsion stabilizer in aqueous dispersions, is subject to reporting for any significant new use. For example, ammonium perfluorooctanoate (APFO)

– when used as an aqueous dispersion agent in fluoropolymer production

– is subject to this SNUR if the final fluoropolymer product is used as part of carpets or to treat carpets. For this rule, fluoropolymer

– but not fluorotelomer-based polymers (FTBP)

– precursors are sp ecifically excluded from reporting obligations . However, fluoropolymers which contain some PFAC contamination, or that use PFOA as an emulsion stabilizer in aqueous dispersions , are included in the definition due to their PFAC content. For example, fluorop olymers using ammonium perfluorooctanoate (APFO) as an emulsifier are subject to this SNUR based on the APFO content

– not the content of the dispersed fluoropolymer (e.g. aqueous dispersion can have as much as 0.1 percent by weight APFO). PF ACs are used in carpets to impart stain, soil, and grease repellant properties. During the manufacturing process, PFACs are utilized in the impregnation of carpets or as a chemical finish which endows fabrics with those characteristics. Long - chain perfluorinated chemic als (LCPFCs) are found world-wide in the environment, wildlife, and humans. They are bioaccumulative in wildlife and humans, and are persistent in the environment (Danish Ministry of the Environment, 2008) . To date, significant adverse effects have not been found in the general human population4 ; however, LCPFCs have been linked to a number of health effects, including thyroid disease and reproductive function (Knox, et al., 2011; Melzer, et al., 2010) . Because of their bioaccumulative and persistent properties, EPA is promulgating a SNUR for all LCPF ACs used in carpet treatments and carpet treatment products. The Agency believes that the LCPFAC chemical substances included in this final rule are no longer being manufactured (including imported) or processed for use as part of carpet or for treating carpet (e.g., for use in the carpet

**▌ pg.**  2 - 6 aftercare market) in the United States , except for use of two chemical substances in carpet cleaning solution. The Agency also believes that LCPFAC chemical substances are not b eing imported as part of carpet. EPA is promulgating a SNUR for any commercial uses of these chemicals, so that the Agency may be informed of any intended use of these chemicals in commerce. 

### 2.2 **Significant New Uses under the Final**  **SNUR** EPA may promulgate a SNUR for a substance when potential use could result in significant changes in human exposure or environmental release levels and/or that concern exists about the substance’s health or environmental effects (40 CFR §721.170). According to TSCA Section 5(a) (2), the determination that a chemical use qualifies as a significant new use must consider all relevant factors, including:
 The projected volume of manufacturing , importation, and processing of the chemical substance;  The extent to which a use changes the type or form of exposure of human beings or the environment to a chemical substance;  The extent to which a use increases the magnitude and duration of exposure of human beings or the environment to a chemical substance; and  The reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce, and disposal of a chemical substance. EPA is defining the significant new use as: 1) the manufacture (including import) or processing of any of the PFAS chemical substances subject to this final rule, for any use except ongoing uses specified in the 2007 PFAS Chemical Substances SNUR at § 721.9582(a)(3) through (a)(5) ; and 2) the manufacture (including import) processing, or import as part of carpet, of any of the LCPFAC chemical substances subject to this final rule for use as part of carpet or to treat carpets, is a significant new use , except for use of two chemical substances in carpet cleaning solution . A company will be expected to submit a SNUN for any PFAS chemical substances or for any LCPFAC substances used in carpet treatment products included in the final SNUR prior to initiating a new use. 

### 2.3 **Chemical Uses 2.3.1**  **PF AS**  **Chemical Substances** In the past, PFAS chemical substances were used in a variety of products, which can be divided into three main use categories: surface treatments, paper protection, and performance chemicals .**SNUR EA for PFAS**  **and L**  **ong Chain PFAC**  **in Carpets Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  2 - 9 **2.3.2 LCPF**  **AC Chemical Substances** LCPFAC chemical substances were used in carpets to impart stain, soil, and grease repellant properties (Kissa, 2001). There are four typical scenarios for chemical application that could lead to the presence of these chemical substances in carpet products. First, these chemical substanc es could be applied to carpet at a carpet and rug mill during the manufacturing process. Secondly, these chemical substances could be applied to carpet after the manufacturing process at a separate finishing facility. Thirdly, treatment products containing these chemical substances could be applied to carpets by final consumers in the post manufacturing stage. In the described scenarios, LCPFAC chemical substances could be domestically produced or imported. In addition, domestically produced carpets could b e made using imported fabrics that had been treated with PFAS or LCPFAC chemical substances. Finally, carpet containing these chemical substances could be imported into the United States as a final product. The Agency believes that the LCPFAC chemical su bstances included in this final rule are no longer being manufactured (including imported) or processed for use as part of carpet or for treating carpet (e.g., for use in the carpet aftercare market) in the United States , except for use of two chemical sub stances in carpet cleaning solution. The Agency also believes that LCPFAC chemical substances are not being imported as part of carpets . 

### 2.4 **Potentially**

**A ffected Companies**  The final SNUR applies to processors as well as to manufacturers (including importers ) of PFAS and LCPFAC chemical substances , as well as importers of LCPFAC chemicals substances as part of carpet (40 CFR §721.5). It will require manuf acturers (including importers ) and processors to notify EPA at least 90 days before commencing the manufact ure, import, or processing of any of the subject chemicals for any significant new use. The final SNUR may also affect firms that currently do not manufacture ( including import) or process any of the chemicals, but who may be interested in manufacturing (including importing) or processing these chemicals in the future. **2.4.1 PF**  **AS Chemical Substances**  The PFAS chemical substances that EPA is adding to the existing PFAS SNUR are chemical substances that have completed the TSCA new chemical review process but have not yet commenced production or import. Any person who commences the manufacture (including import) or processing of a new chemical substance for which that person previously submitted a section 5(a) notice must submit a notice of commencement of manufacture (including import) (40 CFR 720.102 ) . EPA has not received any notices of commencements for these chemical substances, and there is currently no production or import of these chemical substances. If commenced, these chemical substances could be used for the PFAS uses described above, significantly increasing the magnitude and duration of exposure to humans and the environment . **2.4.2 LCPF**  **AC Chemical Substances** The Agency believes that the LCPFAC chemical substances included in this final rule are no longer being manufactured (including imported) or processed for use as part of carpet or for treating carpet (e.g., for use in the carpet aftercare market) in the United States , , except for use of two chemical substances in carpet cleaning solution . The Agency also be lieves that LCPFAC chemical substances are not being imported as part of carpet.**SNUR EA for PFAS**  **and L**  **ong Chain PFAC**  **in Carpets Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  2 - 10 Potentially affected entities will include chemical manufacturers as primary producers of LCPFCs and carpet manufacturers as secondary manufacturers that purchase LCPFCs from domestic or foreign chemical manufacturers for use in carpets . This SNUR might also affect entities that are involved in importing of LCPFAC chemical substances. Although industry phase - out of LCPFCs in carpet treatment products was voluntary, EPA’s comm unication with the carpet industry leads the Agency to believe that LCPFCs used in carpet s subject to this SNUR are no longer manufactured in or imported into the United States . Therefore, there are likely to be no entities affected by this final SNUR. 

### 2.5 **Ar ticle Importation**  The SNUR contains a provision to eliminate the exemption for persons that import the regulated chemical substances as part of articles. This will require importers of consumer articles containing LCPFAC s as part of carpets to notify EPA at least 90 days before importing consumer articles containing LC PF ACs. The rule may also affect firms that do not currently import articles containing the chemicals, but who may be interested in importing these articles in the future or who may be interested in ensuring that the articles they import are in compliance with the requirements of the SNUR. Although there are no specific requirements in the rule for these companies, they may choose to undertake some activities assure themselves that they are not undertaking a new use. **2.5.1 Af** 

**fected Entities**  EPA is concerned about the importation of carpet and carpet care products containing LCPFAC because it may increase human and environmental exposure to LCPFAC chemicals. For example, in Norway the main source of PFOAs in the environment is from imported articles, such as textiles, carpets, paints and lacquers, and coated paper, as there is no current production or use of PFOAs in the country (Vierke et al, 2012 and Norwegian Pollution Control Authority, 2007). Exhibit 2 - 3 contains examples of NAICS codes for firms that may import carpets or carpet treatments . This is not meant to be an exhaustive list, but rather an example of the types of industries that may be impacted by lifting the articles exemption for importing LCPFAC chemical substances as part of carpets .**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  2 - 11 **Exh ibit**  **2 -**  **3 :**  **Examples of Industries that may Import**  **Carpets or Carpet Treatments Containing LCPFA** **Cs NAICS**  **Code Section**  **Description** 31 3 Textile Mills Industries in the Textile Mills subsector group are establishments that transform a basic fiber (natural or synthetic) into a product, such as yarn or fabric that is further manufactured into usable items, such as apparel, sheets, towels, and textile bags for individual or industrial consumption. The further manufacturing may be performed in the same establishment and classified in this subsector, or it may be performed at a separate establishment and be classified elsewhere in manufacturing. The main processes in this subsector include preparation and spinning of fiber, knitting or weaving of fabric, and the finishing of the textile. The NAICS structure follows and captures this process flow. Major industries in this flow, such as preparation of fibers, weaving of fabric, knitting of fabric, and fiber and fabric finishing, are uniquely identified. Texturizing, throwing, twisting, and winding of yarn contains aspects of both fiber preparation and fiber finishing and is classified with preparation of fibers rather than with finishing of fiber. 3 14 Textile Product Mills Industries in the Textile Product Mills subsector group are establishments that make textile products (except apparel). With a few exceptions, processes used in these industries are generally cut and sew (i.e., purchasing fabric and cutting and s ewing to make nonapparel textile produc ts, such as sheets and towels). 423 Merchant Wholesalers,

Durable Goods Industries in the Merchant Wholesalers, Durable Goods subsector sell capital or durable goods to other businesses. Merchant wholesalers generally take title to the goods that they sell; in other words, they buy and sell goods on their own account. Durable goods are new or used items generally with a normal life expectancy of three years or more. Durable goods merchant wholesale trade estab lishments are engaged in wholesaling products, such as motor vehicles, furniture, construction materials, machinery and equipment (including household -ty pe appliances), metals and minerals (except petroleum), sporting goods, toys and hobby goods, recyclabl e materials, and parts. 442 Furniture and Home

Furnishings Stores Industries in the Furniture and Home Furnishings Stores subsector retail new furniture and home furnishings from fixed point- of - sale locations. Establishments in this subsector usually operate from show rooms and have substantial areas for the presentation of their products.**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  2 - 12 **2.5.2 Activities which may Impact the Use of PFCs in the Supply Chai**  **n** State level and international regulatory as well as voluntary actions by firms may impact the use of a chemical within an article. Because suppliers of articles are likely to export to multiple countries, they may find it more cost effective to comply with the more stringent regulations in one country than to have two separate supply chains. Similarly, if a significant downstream consumer refuses to purchase products containing a certain chemical, the supplier may find it more profitable to stop using that chemical for all of its customers. Regulatory and voluntary action regarding the use of PFOAs has been conducted at the national level. Canada currently has an agreement with five companies to work towards the elimination of residual PFOA, residual LC PFA C s and residual precursors in their perfluorochemical products sold in Canada . Germany has recommended maximum concentrations for drinking water (Environment Canada, 2010 and Germany Federal Environmental Agency, 2009). 5 While neither of these actions appli es to the use of PFACs in articles, Norway has proposed to regulate the content of PFOA in consumer products with a percentage by weight limit of 0.0001 percent and 1 μg/m2 for textiles, carpeting and other coated materials (Norwegian Pollution Control Authority, 2010 and European Commission, 2010). However, as detailed in Section 2.3.2 , EPA believes that the LCPFAC chemical substances included in this final rule are no longer being manufactured (including imported) or processed for use as part of carpet or for treating carpet (e.g., for use in the carpet aftercare market) in the United States and that LCPFAC chemical substances are not being imported as part of carpets , except for use of two chemical substances in carpet cleaning solution .

5 Environment Canada defines a perfluorochemical product as a perfluorinated or polyfluorinated chemical product that may contain PFOA, Long Chain PFCAs, Precursors, or mixtures of these substances. Perfluorochemical Products are Fluoropolymers, Fluoropolymer Dispersions, and Fluorotelomer Based Substances. Perfluorochemical Products **do not** include end products and formulated items (i.e., paints, cleaners and surface treatments), the articles to which they are applied (i.e., carpets, textiles and paper), and the articles that are manufactured from them.**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  3 - 1 

## 3. **I ndustry** 

**Compliance Costs** The final SNUR discussed in this report specifies that any manufacture ( including import) or processing of PFAS chemical substances and LCPFCs as part of carpet or to treat carpets for a designated significant new use will require reporting under section 5(a)(1)(A) of TSCA . Theref ore, a firm intending to manufacture (including import) and/or process any of th ese chemical s for these applications must submit a SNUN . Alternatively, a firm can decide not to manufacture (including import) and/or process the s e chemical s or to manufacture (including import) and/or process these chemicals in such a way that it is not considered a significant new use . The firm, therefore, has two options:

 **Option 1: Submit a SNUN.** A SNUN indicates to EPA that the firm would like to manufacture (including imp ort) and/or process the chemical for a significant new use, which, in this case, means ( 1) : the manufacture ( including import) or processing of any of the PFAS chemical substances subject to this final rule, for any use except ongoing uses specified in the 2007 PFAS Chemical Substances SNUR at § 721.9582(a)(3) through (a)(5) ; and ( 2) the manufacture ( including import) or processing, or import as part of carpet, of any of the LCPFAC chemical substances subject to this final rule for use as part of carpet or to treat carpets. The firm must submit the SNUN to EPA at least 90 days before it plans to commence the manufacture (including import) and/or processing of the new use of the substance; the SNUN provides EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs. If EPA allows the manufacture ( including import) and/or processing of any of the PFAS chemical substances subject to the rule or any LCPF AC chemical substances for use as part of carpet or to treat carpets for a significant new use, then the costs associated with this option are the costs of submitting the SNUN (including a user fee) plus, if there is any export of these chemicals, the export notification costs that result from TSCA Section 12 (b) requirements that are automatically triggered for chemicals regulated under TSCA Section 5 (see Section 3.2.7 for details).  **Option 2: Comply wi th SNUR limits (not manufacture**  **(including import**  **) and/or process a new**  **use of the chemical**

). A firm can avoid engaging in a Significant New Use and submitting a SNUN by not manufacturing (including importing) and/or processing any of the chemical substanc es in a manner such that they would be considered new uses. That is, if the firm does not use ( 1) : the manufacture (including import) or processing of any of the PFAS chemical substances subject to this final rule, for any use except ongoing uses specified in the 2007 PFAS Chemical Substances SNUR at § 721.9582(a)(3) through (a)(5) ; and ( 2) does not use the manufacture (including import) or processing, or import as part of carpet, of any of the LCPFAC chemical substances subject to this final rule for use as par t of carpet or to treat carpets, then it will meet all applicable SNUR requirements. While this option avoids the costs of submitting a SNUN, it may entail the “hidden” cost of the foregone profit as a result of not engaging in the commercial activity originally planned, and may involve substituting one of the subject chemicals for another, more costly substance. If the firm elects to produce the chemical for research and development (R&D) purposes only (an exemption for R&D purposes is provi ded in 40 CFR §721.47), it may have costs associated with R&D recordkeeping. In addition, if the firm exports any existing stockpiles of the chemicals, it will incur the export notification costs. The firm may also pursue this option temporarily by complying with SNUR restrictions while also pursuing**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  3 - 2 Option 1. Due to the uncertainty related to this option, and EPA’s expectation that affected entities will select Option 1 , the costs of Option 2 are not fully quantified in this report. The remainder of this chapter estimates the quantified portion of costs associated with the final SNUR . Section 3.1 summarize s the wage rates used in this chapter . Section 3.2 provides the unit industry compliance costs , including the co sts of rule familiarization, registration with the Central Data Exchange (CDX) electronic reporting tool , completing the SNUN form, submission fee, import certification, and export notification . Total costs under each option are presented in Section 3.3 . 

### 3.1 **Wage Rates** The final rule involves activities that may require efforts by employees in three labor classifications: managerial, technical, and clerical. Costs for each activity are calculated by estimating the labor hours required in each labor category and multiplying those burden hours by the wage rate for the corresponding labor category. This section presents the estimated wage rate in each labor category. Loaded wage rates for managerial, technical, and clerical personnel are derived by combining data on wages and fringe benefits with estimates of overhead rates, following the methodology described in Wage Rates for Economic Analysis of the Toxics Release Inven tory Program (EPA, 2002b). Wage data for each labor category for December 2012 are provided by the Employer Costs for Employee Compensation (ECEC) Supplemental Tables available on the BLS website (BLS, 201 3 a). The loaded wage rate is $ 72.87 for managerial labor; $ 64.38 for technical labor; and $ 29.51 for clerical labor. Exhibit 3 - 1 presents the data used to calculate the loaded wage rates for the three labor categories. Appendix A provides more information on the wage rates and inflation factors used in this analysis.**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

### 3.2 **Unit Industry**

**Compliance Costs 3.2.1**  **Rule Familiarization** The final rule requires submitters and their staff to become familiar with the SNUR and its various requirements. Rule familiarization is estimated to require 0.55 hours of technical labor and 0.27 hours of managerial labor, as described in the Economic Analysis of the Premanufacture Notification Electronic Reporting Final Rule (EPA, 2009a), which measures the costs of mandatory electronic reporting of SNUNs and other TSCA Section 5 notices. As shown in Exhibit 3 - 2 , the total labor cost associated with rule familiarization is estimated at $ 54. 84 . **Exhibit 3**  **- 2**  **: Rule Familiarization Burden and Cost for SNUR Submitters**  **Reporting Activit**  **y Clerical Labor**

**▌ pg.**  3 - 4 **3.2.2 CDX Registration, CDX Electronic Signature, and Pay.gov A** **ccount Setup** The final SNUR requires submission of a SNUN for any firm that chooses to manufacture ( including import) and/or process a chemical for a significant new use . F irst- time submitters of any TSCA section 5 notice (including Premanufacture Notices (PMNs), SNUNs, Test Market Exemption (TME) applications, Low Volume Exemption (LVE) notices, Low Exposure/Low Release (LoREX) exemption notices, Biotechnology Notices for genetically modified microorganisms, Notices of Commencement of Manufacture or Import (NOCs), and support documents to Section 5 notices) are required to register their company and key users with the CDX reporting tool, deliver a CDX electronic signature to EPA, and establish and use a Pay.gov E -payment account. 6 These activities are only required of first
- time submitters of any Section 5 notice. These activities are estimated to require the following burden hours , based on the estimates presented in the Economic Analysis of the Premanufacture Notification Electronic Reporting Final Rule (EPA, 2009a):

 **CDX registration .**  EPA estimates that companies will spend approximately 0.18 hours per employee to register with CDX, and that an average of four technical staff members and one manager will need to register for each company, totaling approximately 0.92 hours of burden per company.  **CDX electronic signature .**  EPA estimates that companies will spend 0.25 hours preparing, submitting, and filing an electronic signature agreement (Authentication of Identity) form to EPA per employee. This burden will apply to four technical staff members and one manager per company, totaling 1.25 hours of burden per company. In addition, EPA estimates that a manager will spend an additional 0.50 hours accessing, preparing, and submitting verification forms (Verification of Authorization) for all authorized submitters to EPA. The total burden incurred by companies submitting and then verifying electronic signature agreements is 1.75 hours. Note that this burden does not include any additional time required to contact EPA’s CDX help desk to notify a change of submitter status, should one occur. Filing the electronic signature agreement requires an additional mailing cost of $ 2.60 per company (including five $ 0.46 stamps 7 and five $0.06 business envelopes 8 ).  **Payment via Pay.gov account .**  EPA estimates that one manager per company will spend approximately 0.13 hours setting up a Pay.gov ID account, logging into the system, finding the appropriate form, and filling it out. This burden does not include the time required to click ‘submit’ on the form and wait for payment processing. As shown in Exhibit 3 - 3 , the labor cost consist s of CDX registration, CDX electronic signature, and Pay.gov account setup by a first -time submitter . As noted above, an additional $ 2.60 in mailing cost per company is attributable to these activities, for a total cost of approximately $ 192 per company . 6 Although the proposed rule does not require submitters to establish and use a Pay .gov account, the burden estimates in this analysis are conservative insofar as to include the use of Pay.gov as a required activity. 7 Price for a stamp was taken from the U.S. Postal Service website on April 9, 2013. (See U.S. PS , 2013) 8 Price for an envelope was determined based on the per unit price of a regular business envelope. See “ Staples® #10, Self

Unrounded values were used in calculations . **Source s**  **:** Wa ge rates: see Exhibit 3 - 1 ; Burden estimates: EPA, 2009a. **3.2.3 Form Completion and Submission Fee**  Respondents who choose to submit a SNUN are required to gather and submit information regarding the data elements identified in the applicable SNUN reporting form. The methodology and calculations used in this analysis assume that the employee responsible for collecting, filling out, and submitting the requested information has a reasonable level of familiarity with the company and knowledge of operations at the site. It is assumed that for most entities these tasks are similar to other employee duties that require familiarity with EPA, State, and other Federal agency requests for chemical information and do not require additional familiarization or training beyond the basic rule familiarization described above. In addition, this analysis focuses on the marginal costs of submitting information for the final rule and not the total costs for the company to comply with a range of other Federal and State environmental, health, and safety regulations or accounting requirements that rely on this type of information . Estimates of the costs of completing a Significant New Use Notice (SNUN) form are based on the costs of completing a PMN submission, since the data requirements are the same and the same form is used for both. The PMN submission costs came from EPA's 1994 Regulatory Impact Analysis of Amendments to Regulations for TSCA Section 5 Premanufacture Notifications, which relied on industry estimates of the effort needed to collect and compile all data required for a PMN submission, prepare the form, submit the form and data to EPA, and maintain a file of the submission (EPA, 1994, Table III - 2 and pages III - 11, - 12, and - 13). The 1994 estimates were based on a survey conducted by the Chemical Manufacturers Association, which became the American Chemistry Council. These burdens include “the time spent reading and becoming familiar with the form, gathering the required information and preparing the report, producing sanitized responses for items claimed as confidential business information, and maintaining a file of the submission” (EPA, 1994. p. III 11 - 13). The burden associated with SNUN submission and preparation has been adjusted to reflect burden reductions resulting from the 2009 final PMN Electronic Reporting (ePMN) Rule that requires the electronic submissi on of all TSCA section 5 notices. Electronic submission of SNUN forms is expected to**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  3 - 6 remove all clerical burden and reduce the recordkeeping burden associated with preparing a SNUN (EPA, 2009a). 9 In addition, electronic submission is expected to generate and an additional 0.18 hours of technical burden, for the completion of the User Fee Payment Identification Number and email address data elements on the electronic SNUN form. SNUN form completion and electronic submission is estimated to require approximately 74 hours of technical labor and 18 hours of managerial labor (EPA, 2009a). Exhibit 3 -4 combines the estimated reporting burden and loaded wage rates for all three labor categories to estimate the per- SNUN cost of form completion. The labor cost incurred by a SNUN submission for both large and small business submitters is estimated at $ 6 , 089 . **Exhibit 3**  **- 4**  **: Industry**  **Cost Estimate to Complete the SNUN Form Reportin**  **g Activit y**  **Clerical Labor**

Wage rates presented in this table are rounded; however, unrounded values were used in calculations . For this reason, total labor costs may not equal the product of rounded values. 3. The estimate of zero clerical burden is taken from the Economic Analysis of the Premanufacture Notice Electronic Reporting Final Rule (EPA, 2009a, page 7) . 4. Technical and managerial labor burden is from the PMN Amendments RIA (EPA , 1994, Table III - 2). An additional eleven minutes (0.18 hours) of technical burden is estimated to complete the User Fee Payment Identification Number and Email Address data elements on the Electronic SNUN form (EPA, 2009a, page 15). **Sources** : Burden estimated: EPA, 1994 and EPA, 2009a; Wage rates: see Exhibit 3 - 1 . In addition, each submitting large business must pay a $2,500 per- SNUN submission fee, and each submitting small business must pay a $100 per- SNUN submission fee. Exhibit 3 - 5 adds the labor cost and submission fee to estimate the total cost of a SNUN submission. The total cost of a SNUN submission is $ 8, 589 for large business submitters and $ 6, 189 for small business submitters.

9 The Economic Analysis of the Premanufacture Notification Electronic Reporting Final Rule (EPA, 2009a) reported a 0.5 hour clerical and a 0.5 hour technical burden associated with recordkeeping in addition to the burden estimates from the 1994 RIA (EPA, 1994, p. III - 14). These burden estimates (the 0.5 for clerical burden and 0.5 for technical burden) are based on the recordkeeping burden for polymer exceptions and not the recordkeeping burden associated with PMN submissions. Therefore, for this analysis, the 0.5 hour for clerical labor and the 0.5 hour for technical labor were removed. It is important to note that for this analysis, clerical burden c hanges are not applicable because the entire clerical burden is assumed to be eliminated under the electronic reporting requirements . In summary, we do not include the one hour recordkeeping burden (0.5 hour for clerical, 0.5 for technical) reported in the ePMN EA.**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

Some EPA reports have assumed that SNUN recordkeeping hours will be five percent of SNUN submission hours, or about five to six hours. For this report, the SNUN recordkeeping hours were included in the SNUN submission hours (see Section 3.2.3) and the SNUN recordkeeping costs under 40 CFR §721.40 were not separately estimated. **Recordkeeping for Companies t**  **hat D**  **o N**  **ot Submit a SNUN** If a firm that manufactures ( including imports ) or processes a substance subject to the final SNUR chooses not to submit a SNUN, they must keep records that document compliance with SNUR conditions for avoiding a Significant New Use. Such recordkeeping requirements essentially involve copying and filing relevant records, including those related to category of use. Records must be maintained for five years from the date of their creation (40 CFR 721.40). For firms that choose to not submit a SNUN, costs for compliance with the recordkeeping requirements are estimated to be five percent of the reporting burden for reporting information for a specific section of the SNUN form and are performed by clerical staff (EPA, 2005b, pages 10 and 14). EPA used the per- activity burden for reporting, human exposure, category of use and releases to the environment presented in the Information Collection Request (ICR) for TSCA Section 5(a)(2) Significant New Use Rules for Existing Chemicals (Renewal) (EPA, 2005b, page 12). Any clerical burden associated with these activities was removed to reflect the burden reduction associated with electronic submissions (EPA, 2009a). The recordkeeping burden for a company that does not submit a SNUN is estimated at 0.15 hours and $ 9. 66 and is derived in Exhibit 3 - 6 . **Exhibit 3**  **- 6**  **: An**  **nual Per -**  **Chemical Costs of Recordkeeping Requirement for**

**▌ pg.**  3 - 8 **3.2.5 Customer Notification**  Manufacturers (including importers) and processors of chemicals subject to SNURs must notify recipients of such chemicals of the SNUR or verify that knowledge of the SNUR has been otherwise acquired by recipients, or that the recipients are unable to engage in significant new uses. Since it is not expected that all such entities will have complete knowledge of all uses of any products subject to a SNUR, and because filing a SNUN could require significantly more burden, it is assumed that manufacturers, (including importers) and processors will most often choose to notify their customers of SNUR regulatory activities. As this notification may be accomplished by simply annotating an MSDS, EPA estimates the associated burden to be about one hour of a technical employee's time or $64.38 per manufactu

rer (including importer) or processor per chemical. The final SNUR will cover PFAS Chemical Substances and LCPFACs for use as part of carpet or to treat carpets ; however EPA believes these chemicals are not used in the U.S. and therefore no manufacturer s , processor s , or importers will be affected . Therefore, customer notifications will not be necessary. **3.2.6 Import Certification**  In general, promulgation of a SNUR triggers a TSCA Section 13 import certification requirement and the corresponding regulations at 19 CFR §12.118 to 12.127 and 19 CFR §127.28 for all imports of the relevant chemical substances. Thus, any U.S. manufacturer (including importer) or processor receiving an imported shipment of chemicals subject to the final SNUR will have to certify that all chemical substances in the shipment either comply with all applicable rules and orders under TSCA or that all chemical substances in the shipment are not subject to TSCA. 10 The statement must be on or attached to a commercial invoice or entry document belonging to the imported shipment. Import certification is fulfilled by checking a box on an invoice or entry document and EPA assumes that it generally imposes no additional burden or cost on the importer. Any potential burden associated with submitter’s familiarization with this requirement is assumed to be included in the more general SNUR familiarization burden discussed above. **3.2.7 Export Notification**  Under Section 12(b) of TSCA, exporters must notify EPA if they export or intend to export a chemical subject to various TSCA sections (40 CFR §707.60 through 75). For TSCA 5(a)(2) (the section under which EPA promulgates significant new use rules) and certain other TSCA sections, this is a one -time notification requirement 11 per destination country for each exporter of a chemical substance. After receiving a notification from a firm, EPA notifies the importing country and the

10 The exact statements are as follows: For imports of chemical substances subject to TSCA, “I certify that all chemical substances in this shipment comply with all applicable rules or orders under TSCA and that I am not offering a chemical substance for entry in violation of TSCA or any applicable rule or order under TSCA.” For imports of chemical substances not subject to TSCA (e.g., pesticides), “I certify that all chemicals in this shipment are not subject to TSCA.” (40 CFR 707.20 ) 11 On Novem

ber 14, 2006, EPA revised the export notification requirement for chemicals subject to TSCA §5(a)(2), 5(b), 5(e)(1) and 5(e)(2) from an annual to a one -time requirement per destination country for each exporter (November 14, 2006, 71 FR 66234).**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  3 - 9 United States State Department (40 CFR §707.70). To calculate the burden associated with making a single export notification, EPA first estimated the average annual number of export notifications made by an exporter. EPA then derived the annual and per notification burden associated with preparing and submitting an export notification. EPA estimated the average burden associated with making a s ingle notification, but did not estimate either the total number of exporters of a SNUR chemical or the number of notifications per SNUR chemical. This is because the SNURs apply to a variety of different chemicals with a variety of unrelated uses, manufac turer s, and processors, making it impractical within the resources available for this report to assess the potential number of exporters and importing countries per chemical. Most underlying data in this section come from the (2009 TSCA Section 12(b) ICR), ICR No.: 0795.13 OMB Control Number 2070 - 0030 [Information Collection Request for] Notification of Chemical Exports - TSCA Section 12(b) Supporting Statement for Request for OMB Review under the Paperwork Reduction Act (EPA, 2009b) . **Estimated Number of A nnual Export Notifications per Exporter**  EPA’s 2009 TSCA Section 12(b) ICR estimated that the average exporter making notifications would make 12 notifications per year. 12 This includes notifications resulting from SNURs and notifications resulting from other TSCA activities. Therefore, it is likely that an exporter will make less than 12 notifications per year as a result of this final SNUR. A notification is typically no more than one page per chemical/country combination, and one notification mailing often includes multiple chemicals and/or destination countries. 13 The percent of notifications resulting from SNURs in general is unknown, and it is also unknown how many notifications may result from this rulemaking, as not all manufacturers may choose to export a chemical, or they may make several notifications for a single chemical. **Exporter Costs** The 2009 TSCA Section 12(b) ICR (EPA, 2009b, page 11, Table 3), estimated the annual export notification cost for an exporter under the one -time export notification requirement. These costs include the cost to the exporter of compiling a list of their products that are subject to TSCA Section 12(b) requirements, writing or revising an export notification letter to EPA, checking the outgoing shipments, and sending the notification letters with the associated shipping costs . The per-notification cost was calculated based on the average burden per firm. Exporters who make a larger number of notifications per year may benefit from economies of scale and have lower costs per notification; conversely firms making fewer notifications may have a higher cost per notification.

12 EPA cal culated the average num ber of export notifications per exporter in the 2009 TSCA Section 12(b) ICR (EPA, 2009b) by dividing the estimated number of submitted notifications (3,500) by the estimated number of exporters (300 ). 13 Based on review

by an EPA economist of notifications received under TSCA Sections 4, 5 and 6 over approximately three weeks in early 2010.**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  3 - 10 **Estimated Submission (Mailing) Costs.** Regulated companies will incur mailing costs for export notifications delivered to EPA. Notifications are assumed shipped via the U.S. Postal Service (U . S . PS) as first - class registered mail with a return receipt (U . S . PS, 20 12 ). The estimated per- shipment and annual mailing costs incurred by individual submitters are detailed in Exhibit 3 - 7 . **Exhibit 3**  **- 7**  **: Derivation of Total Mailing Cost for 12**  **Notices Postal**  **S ervice**  **Cost** Registered mail, regular, with $0 declared value $11.20 Return receipt, requested at time of mailing (receive by mail) $2.55 Postage, regular First Class, up to 1 ounce $0.46 **Cost per export notice -**  **Subtotal $14.21**  × 12 **Total Mailing Cost for 12 Notices $17**  **1 Source:**  Mailing rates are from the U . S . Postal Service web site as of January 2012 ( http://www.usps.com/prices/ ) . The assumption on the mailing method is based on th e Economic Analysis of the Proposed Change to TSCA Section 12(b) Export Notification Requirements, November 2005 (EPA, 2005a), as clarified in a later SNUR economic analysis (EPA, 2007c, Table 8). **Com pile and Maintain the List of Products.**  Since TSCA §12(b) information collection activity has been in place for twenty years, most respondents will have already developed a list of their products subject to TSCA §12(b) export notification. Respondents need only check for new regulations promulgated and any new products exported by the company. Updating the list is estimated to take an average of one hour of technical time, which may also include some proportion of legal time (EPA, 2009b) . The total burden can vary from two hours per year up to two hours per month, depending on the number of products exported by the company and the number of their products subject to TSCA §12(b) (EPA, 2009b). The number of submitters per year who report under TSCA §12(b) has varied over time, rising from around 160 in 1991 to over 460 in 2000, and declining since. In the most recent TSCA §12(b) ICR, EPA estimated that there will be approximately 300 submitters per year in near- future years (EPA, 2009b ). Of these 300 submitters, EPA estimated that 200 companies were near the lower burden estimate of two hours per year, and 100 companies were near the upper estimate of 24 hours per year. Compiling the list for all respondents was therefore estimated to take 2,800 hours (2 hours x 200 firms plus 24 hours x 100 firms), or an average of about 9.3 hours of technical time per firm per year for 12 notifications per year (EPA, 2009b ). **Write or Revise Export Notification.** Companies that export chemicals subject to T SCA §12(b) reporting must prepare an export notification to send to EPA when export shipments are made. Time for initial preparation of the export notice may vary depending on whether the company has prior experience with this requirement. This step is estimated to take an average of one hour of technical time (which may also include some proportion of legal time) per firm per year for 12 notifications per year (EPA, 2009b ). **Check Orders and Send Notifications.** Companies that export chemicals subject to TSCA §12(b) reporting must check outgoing shipments against the list of their products described above. A form letter notifying EPA and providing the required data must be printed and mailed within the required**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

Burden hour estimates are from ICR No.: 0795.13 ICR for Notification of Chemical Exports - TSCA Section 12(b) Supporting Statement for Request for OMB Review under the Paperwork Reduction Act (EPA, 2009b, p.10) . **3.2.8 Article Importation**  The final SNUR will require importers of LCPFAC chemical substances as part of carpets to notify EPA at least 90 days before importing any articles containing chemicals subject to the final rule. The final rule may also affect firms that do not currently import articles containing the chemicals, but who may be interested in importing these articles in the future. Importers have varying levels of knowledge about the chemical content of the articles they import, yet under TSCA the definition of “manufacture” means to “import..., produce or manufacture” and importers are responsible parties under the final SNUR. In order to understand and monitor their liability, companies might undertake a range of activities to ensure that the articles they import do not violate existing regulations. **3.2.9 Potential Compliance A** **ctivities (A rticle Importers)**  The rule does not prescribe steps that an importer must take to identify a chemical subject to a SNUR in articles, there are a variety of specific actions that a company could take to identify specific substances in its articles. Importers are expected to take actions that are commensurate with the level of risk each company perceives, and the resources it has available. There is currently no single widely accepted standard procedure to identify regulated chemicals in a supply chain ; however, there are a number of organizations that help provide information on the**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  3 - 12 content of articles, organize declarations from suppli ers, or certify suppliers based on materials or processes used. Importers subject to SNURs may refer to these sources for assistance in their own strategy to identify a chemical subject to a SNUR in articles. ASTM International, formerly known as the American Society for Testing and Materials (ASTM), has developed a Standard Guide for Assessment of Materials and Products for Declarable Substances (“ASTM F2577”) which provides guidance for the decision process to assess materials and pro ducts for declarable substances. Based on ASTM F2577, the following list includes activities that an importer might perform to identify any restricted chemicals in imported articles. This list is intended to capture the general types of activities that might be performed. **1) Understand applicable requirements (Per Firm Cost).**  The importer would read and understand the SNUR, within the context of the company’s products. This burden is as derived in Section 3.2.1 f this report . **2) Identify th**  **e type of imported articles that potentially contain the restricted substances (Per Firm Co**  **st).** This determination may be done based on an understanding of the uses of the restricted substance and the application of any a priori knowledge of the material and its manufacture to assess the probability that each regulated substance may be present. **3) Identify all suppliers involved**  **(Per Firm Cost).** The importer may choose to identify all suppliers from whom the articles identified in the previous step are imported and , as appropriate, make them aware of the importer’s potential notice obligations respecting the regulated chemical substances. **4) Collect data from suppliers (Per Article Cost).**  Imp orters may choose to obtain verification fro m suppliers identified in step 3 that the regulated chemical substance is not found in the article. This may be accomplished through, for example, agreements with suppliers, declarations through databases or surveys, or by using a third-party certification system. **5) Chemical testing (Per Article Cost).**  Importers may perform their own laboratory testing of certain articles (or components of articles) to determine if they contain the restricted substance. **6) Recordkeeping (Per Firm Cost).**  The importer may choose to keep records confirming the activities completed. Exhibit 3 - 9 contains the cost ranges associated with the above activiti es. The activities and cost derivations are discussed in more detail in Understanding the Costs Associated with Eliminating Exemptions for Articles in SNURs (EPA, 2013).**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  3 - 14 Variation in costs associated with these activities would depend on a company’s level of activity to comply with other regulations on chemicals in articles, the complexity of the supply chains; and the size of the company. Total costs per article importer will further depend on the number o f affected articles and the frequency of supplier change. Total c osts associated with these activities to any article importer are not quantified, but are believed to be minimal for this particular SNUR for a variety of reasons outlined below . Firms with less experience with other regulations that are planning to import articles that could potentially be composed of the regulated chemicals or those importers who choose to look at articles they are currently importing may incur a larger burden should they choose to conduct some or all of the activities listed above to ensure compliance. For example these firms may choose to reach out to a wide variety of upstream firms to gather information on the chemical content of articles, such as , through MSDS s or other documentation. Costs associated with these activities are not quantified, but are believed to be very minimal as associated with this particular SNUR. As detailed in Section 2.3.2 , EPA believes that the LCPFAC chemical substances included in this final rule are no longer being manufactured (including imported) or processed for use as part of carpet or for treating carpet (e.g., for use in the carpet aftercare market) in the United States and that LCPFAC chemical substances are not being imported as part of carpets, except for use of two chemical substances in carpet cleaning solution . Therefore, EPA believes that article importers would incur costs at the lower end of the ranges presented in**Error! Reference source not found.**  , as a result of this rule. For those companies choosing to undertake actions to assess the composition of the articles they import, EPA expects that in all likelihood, these importers would take actions that are commensurate with the level of risk (of a chemical to be a part of an article) each company perceives, and the resources it has available. 

### 3.3 **Summary**

**of p er Submission Co**  **sts, by Option**  The number of firms affected that do not make submissions to EPA (see Option 2 in Exhibit 3 - 10 ) is not known; therefore, costs are not aggregated across the affected entities. The following table summarizes the per- company per- chemical costs to comply with the final rule amendment, as described in more detail in section 3.2 above.**SNUR EA for Long Chain PFACs Contract #**  **EP -** **W -** **08 -**  **010**

1. Electronic submission of a Significant New Use Notice (SNUN), indicating to EPA that the firm would like to manufacture (including import ) or process the chemical for a Significant New Use as defined in the SNUR. Costs of submitting a SNUN, including rule familiarization, CDX registration (for companies that are first -time submitters), form completion, user fee, export notification, and any test costs . $ 54.84 rule familiarization cost; $ 8,589 submission cost (including SNUN recordkeeping under 40 CFR §721.40 and fee $2,500 for large businesses). EPA usually receives well under ten SNUNs per year. Export notifications costs are estimated at $ 84.22 per notification; total cost per company would vary. First time submitters would incur $ 191.91 for CDX registration and associated activities. Companies manufacturing (including importing ) or processing a chemical currently used in commerce in the United States would incur a cost $ 64.38 for notifying consumers of SNUR regulatory activities.

2. Manufacture(including import ) or process in a way that avoids a Significant New Use. Cost of the profit foregone as a result of not engaging in the commercial activity originally planned (opportunity costs), recordkeeping, and export notification costs. Opportunity costs are not quan tified. Other costs include rule familiarization ($ 54.84 ), recordkeeping ($ 9.66 ), export notification costs ($ 84.22 per notification), and customer notification ($ 64.38 ) may apply . Costs associated with article importation may include activities such as article identification ($130 to $1,550), supplier identification ($950) recordkeeping ($10), collecting data from suppliers ($5 to $515 per article), and testing ($130 per article tested). **Notes:** 1 Firms may be subject to both options at once since submission of a SNUN results in profits foregone as a result of not manufa cturing (including importing ) or processing the chemical. 2 Quantified costs are attributable to the SNUR only if a firm would not otherwise follow the specified practices. Costs are detailed in Section 3.2 . 3 EPA does not require the development of test data for submission of a SNUN, although a firm may submit test data already in its possession and/or describe any other available data. Because EPA does not require the development of test data, EPA assumes t hat no firms will incur testing costs as a result of the SNUR. 

### 3.4 **Likelihood of SNUN Submission** This analysis assumes that no entities are expected to submit a SNUN. EPA has, over the years, promulgated SNURs that cover a total of more than 1,000 chemicals. In response, the Agency receives only a handful of SNUNs per year. For example, the number of SNUNs received was six in Federal fiscal year (FY) 2007, eight in FY2008, seven in FY2009 , two in FY2010, and ten in FY2011 . 14 In addition, as discussed in sections 2.3 , all of the chemicals sub ject to this final rule are currently not being manufactured (including imported) or processed. Itis important to note that LCPFCs have recently been a focus of EPA activities aimed to reduce these chemicals , which resulted in a drive by industry to stop using LCPF ACs as part of carpet or to treat carpets . Th erefore, it is unlikely that manufacturers will resume use of LCPF ACs in carpets or carpet treatments . This suggests that it is unlikely a firm will submit a SNUN .

**▌ pg.**  3 - 16 

### 3.5 **Potential for Subsequent Regulatory Ac**  **tions** The Agency recognizes that if submission of a SNUN does result from a SNUR, the Agency may take additional regulatory actions under TSCA. These additional regulatory actions might be necessary to further evaluate an intended new use and associated activities, or to prohibit or limit that activity before it occurs to prevent unreasonable risk of injury to human health or the environment. It is not known what specific subsequent regulatory actions, if any, the Agency may determine are necessary after reviewing a SNUN. Any such actions are highly dependent on the circumstances surrounding the individual SNUN (e.g., available information and scientific understanding about the chemical and its risks at the time the SNUN is being reviewed). Should the Ag ency’s review of the SNUN result in further regulatory actions, the Agency would initiate and follow the appropriate procedures for taking those actions. Included in those procedures would be an assessment of the costs and benefits of those actions.**SNUR EA for PFAS**  **and Long Chai**  **n PFAC**  **in Carpets**

## 4. **Agenc y**  **Costs** As described in the following sections, EPA’s costs to review and process SNUN submissions are assumed to be the same as EPA costs to review PMNs. 

### 4.1 **Labor Rates for EPA Staff**  Agency labor costs are calculated based on ann ual Federal salaries for the Washington -Baltimore area published by the Office of Personnel Management effective January 2012 (OPM, 20 12 ). EPA assumes that, on average, a federal GS - 13, Step 5 full -time equivalent (FTE) will conduct its collection and administrative activities under the final rule. 15 The average salary for a GS - 13 Step 5 employee was $100,904 in 2011 without fringe benefits and overhead costs. In order to derive the fully loaded salary, EPA multiplied the annual salary by an assumed loading factor of 1.6 to reflect federal fringe benefits and overhead (EPA, 2009c) , which results in a fully loaded annual salary of $161,446 (see Exhibit 4 - 1 ). Dividing the fully loaded annual salary by 2,080 hours (i.e., the number of hours in a work year) yields an estimated hourly FTE wage rate of $77.62. Fully loaded costs for Agency labor are shown in Exhibit 4 - 1 . **Exhibit 4**  **- 1**  **: Derivation of Loaded A** **gency Wage Rates**  **, 2012**  **Labor Category**  **Data Source Date**  **Wage Fringe**  **Benefit Fringes**

1994 EPA report, Regulatory Impact Analysis of Amendments to Regulations for TSCA Section 5 Premanufacture Notifications (EPA, 1994 ). The Agency burden associated with processing a PMN has been adjusted to reflect burden reductions resulting from the 2009 final PMN Electronic Reporting (ePMN) Rule that requires the electronic submission of all TSCA section 5 notices. Electronic submission of SNUN forms is expected to reduce Agency burden by 16.5 percent (EPA, 2009b, p.28 ). For each review step, the “EPA staff” cost is calculated by multiplying the number of FTEs (in the first column) by the fully loaded hourly salary . This shows EPA staff cost for chemicals requiring the selected review step. The Extramural Cost column shows costs for contractor support and other outside purchases for chemicals requiring the sele cted review step , and is inflated from 1993 prices using the Bureau of Labor Statistics (BLS) Employment Cost Index (ECI) data (BLS, 2013c ). The ECI for total compensation (not seasonally adjusted) of private industry professional and related workers (Seri es ID CIU2010000120000I) is used be cause it is the only series with continuous data since 1985, and that includes professional and technical labor, which perform the majority of Agency extramural activities .

The ‘ Percent of Cases column ’ in Exhibit 4 - 3 is a weighting factor applied to reflect the fact that not all chemicals require each review step. For example, in the PMN process, all chemicals require Administrative Prescreening, but not all chemicals require the intensive scrutiny of “Standard Review.” The three types of submissions resulting from a SNUR may have weighting factors that differ from each other and from the weighting factors for PMNs. Changes in weighting factors could caus e actual review costs to be higher or lower than calculated here. For example, some SNUNs**SNUR EA for PFAS**  **and Long Chai**  **n PFAC**  **in Carpets**

**▌ pg.**  4 - 3

require little review because they are determined to be “invalid”

– i.e. not required in the first place. However, often a SNUN may take more Agency time than a typic al PMN because of factors such as the need to retrieve old PMN records from archives, and the likelihood that more data requiring EPA review are submitted with a SNUN than would be submitted on average with a PMN. Resources were not available to update the review hours to reflect the current review process or to tailor the cost estimates to SNUNs. Therefore, for this analysis, the review steps and weighting factors are assumed to be the same as those derived in 1994 for PMNs. Values in the ‘ Weighted Cost ’ column are calculated by multiplying the un -weighted c osts (EPA staff cost plus extramural costs) by the percentage of cases requiring this review step. Weighted costs are then multiplied by the burden reduction of 16.5 percent to account for burden savings generated electronic submission. This calculation yields total Agency costs of $ 5, 086 per SNUN, for submission review and processing, as shown in Exhibit 4 - 3 .**SNUR EA for PFAS**  **and Long Chai**  **n PFAC**  **in Carpets Contract #**  **EP -** **W -** **08 -**  **010**

### 4.3 **Export Notification Cost** Under TSCA Section 12(b), exporters must notify EPA if they intend to export chemicals subject to SNURs, as described in Section 3.2.7 . The Agency burden and cost due to TSCA §12(b) export notification result from three tasks. In the first task, EPA receives export notifications from companies that intend to export one of the chemicals subject to TSCA §12(b) (EPA, 2009b ). In the second task, EPA staff prepares separate notification letters that are subsequently reviewed and delivered to importing countries, their embassies, or representatives, and to the importing country’s U . S . embassies (EPA, 2009b ). (See Exhibit 3 - 7 for the cost of mailing one notification). The third task is comprised of EPA staff responses to public inquiries and other TSCA 12(b) activities. The work of responding to non -routine requests for information and clarification from industry and importing countries, and of handling other tasks associated with the TSCA §12(b) program, was estimated to require roughly 400 hours per year (EPA, 2009b). Since the current rulemaking covers only a very small percent of the chemicals subject to TSCA 12(b) reporting, a very small percent of such activity will be attributable to the current rulemaking. Because it is unknown how many, if any, notifications EPA will receive or send as a result of the current rulemaking, the costs to the Agency are presented per activity. The estimated burden for the first two Agency activities is provided in Exhibit 4 -4 . To estimate the Agency cost, hourly burdens are multiplied by the loaded wage rate of a GS - 13, Step 5, which is derive d in Exhibit 4 - 1 . **Exhibit 4**  **- 4**  **: TSC**  **A 12(b) Export Notification Cost: A** **gency Burden per A ctivity**

## 5. **Benefits** A SNUN submission provides EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs. It allows the Agency to take immediate action to mitigate an activity that the Agency deems harmful to the environment or human health. Thesauri allows EPA to evaluate the use of, or exposure to these chemicals and allow the Agency to take preventive action to limit or prohibit any Significant New Use. Long - chain perfluorinated chemicals (LCPFCs) are found world-wide in the environment, wildlife, and humans. They are bioaccumulative in wildlife and humans, are persistent in the environment , and toxic to mammalian species (Danish Ministry of the Environment, 2008 and OECD, 2002 ) . Based on currently available information, EPA believes that while all PFAS chemical substances are expected to persist, the length of the perfluorinated chain may also have an effect on bioaccumulation and toxicity, and that chemical substances with longer carbon chain lengths may be of greater concern than those with shorter chain lengths (3M Company, 1999b, 3M Company, 1999c, and Kudo et.al , 2001). LCPFAC chemical substances have been detected in human blood samples throughout the United States and the world. These compounds have also been detected in human breast milk, liver, umbilical cord blood, and seminal plasma . Individual samples collected on perfluorinated chemical substances in the National Health and Nutrition Examination Survey (NHANES ) 1999 - 2009 are similar across teen s and adults; however , pooled data from NHANES 2001 - 2002 indicate that most of the levels of perfluorinated compounds are higher in children age s 3 - 11 years compared to adults (EPA, 2009d). To date, significant adverse effects have not been found in the general human population 16 ; however, LCPFCs have been linked to a number of health effects, including thyroid disease and reproductive function (Knox, et al., 2011; Melzer, et al., 2010) . The SNUR will allow EPA to 

### address the potential environmental and human health effects that may result from releases of PFAS and LCPFAC chemical substances into the environment, by allowing the Agency to evaluate the use of these chemicals, and to take preventive action to limit or prohibit any Significant New Use 

### . EPA also expects that the rule may restrict future uses of the chemicals, as a company may choose modify planned uses, in such a way that does not trigger a SNUR, as opposed to submitting a SNUN. Therefore, the SNUR may limit future exposure to the chemicals.

## 6. **Ad d**  **itional An**  **al ys**  **es 6.1**  **Regulatory**

**Flexibility A ct**  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 will not have a significant adverse economic impact on a subs tantial number of small entities. The rationale supporting this conclusion is as follows. The requirement to submit a SNUN 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. Where a use is new, by definition no small or large entities presently engage in such activities. Although some small entities may decide to manufacture or process a substance for the new use after the SNUR is promulgated, EPA receives very few SNUNs, and few of those are submitted by small entities. In response to the promulgation of SNURs covering over 1 , 000 chemical substances, the Agency receives only a handful of SNUNs per year. For example, the number of SNUNs was four in Federal fiscal ye ar 2005, eight in FY2006, six in FY2007, eight in FY2008, seven in FY2009, two in 2010, and ten in 2011 (EPA, 2012), for an average of 6 per year from all SNURs. EPA has no reason to believe that this SNUR will alter the pattern of SNUN submissions that EPA has historically seen. In addition, the estimated reporting cost for submission of a SNUN is minimal regardless of the size of the firm, averaging about $8, 6 00 including SNUN recordkeeping and reporting costs. The Agency currently offers some relief to c ertain small businesses with sales (including those of subsidiary/parent companies) of less than $40 million per year by reducing the SNUN submission fee from $2,500 to $100. This lower fee reduces the cost of submitting a SNUN to about $ 6,200 for smaller firms. During the six year period from 2005 - 2010, only three submitters self - identified as small in their SNUN submission 17 (EPA, 2012). EPA believes the cost of submitting a SNUN is relatively small compared the cost of developing and marketing a chemical new to a firm and that the requirement to submit a SNUN generally does not have a signific ant economic impact. EPA believes that the potential economic impact of complying with a SNUR is not expected to be significant or adversely affect a substantial num ber of small entities . 

### 6.2 **Unfunded Mandates Reform A ct (UMRA** **)** The final rule does not impose any enforceable duty, contain any unfunded mandate, or otherwise have any effect on small governments because none of the current producers of the subject chemicals are governments. Additionally, it is not expected that any governments will initiate production of these chemical s. 

### 6.3 **Paperwork Reduction A ct (PRA** **)** 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 C ontrol number. The OMB control numbers for EPA's regulations in title 40 of the CFR, after

17 The three “small” submitters were identified by review of actual SNUN submissions from the years 2005 - 2010.**SNUR EA for PFAS**  **and Long Chain**  **PFAC in**  **Carpets Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  **6 -**  **3** appearing in the Federal Register, are listed in 40 CFR, part 9, and included on the related c ollection instrument, or form, if applicable. The information collection requirements related to this action have already been approved by OMB pursuant to the PRA under OMB control numbers 2070 - 0038 (EPA ICR No. 1188) and 2070 - 0030 (EPA ICR No. 0795). If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average 98.2 hours per response: 0.82 hours for rule familiarization (Section 3.2.1 ), 2.80 hours for CDX registration, CDX electronic signature, and pay.gov account setup (Section 3.2.2 ), 92.2 hours for form completion, submission and recordkeeping under CFR §721.40 (Sections 3.2.3 ), 1 hour for consumer notifications (Section 3.2.5 ) and 1.36 hours for export notification (Section 3.2.7 ). The burdens for rule familiarization, CDX registration, CDX electronic signature, pay.gov account setup form completion, submission, and recordkeeping are approved under EPA ICR No. 1188 (O MB control number 2070 - 0038 ). The burden for export notification is approved under EPA ICR No. 0795 (OMB control number 2070 - 0030). 

### 6.4 **Executive Order 13132, Federalism** Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure “meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.” Policies that have federalism implications are defined in the Executive Order to include regulations that have “substantial direct effects on the 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” (64 FR 43255, Augu st 10, 1999). The final rule establishes reporting and recordkeeping requirements that apply to manufacturers (including importers) and processors of certain chemicals. EPA has no information to indicate that any state or local government manufactures or processes the chemical substances covered by this action. 

### 6.5 **Executive Order 12898, Environmental Justice** Executive Order 12898, “Federal Actions to Address Environmental Justice in Minority Populations and Low Income Populations” (59 FR 7629, February 16, 1994), establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, a s 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. The information collected under this final rule wi ll assist EPA and others in determining the potential hazards and risks associated with various chemicals manufactured and used at high production volumes. Although not directly impacting environmental justice -related concerns, this information will enable the Agency to better protect human health and the environment, including in low- income and minority communities.**SNUR EA for PFAS**  **and Long Chain**  **PFAC in**  **Carpets Contract #**  **EP -** **W -** **08 -**  **010**

### 6.6 **Executive Order 13045, Protection of Children** Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks ( 62 FR 19885, April 23, 1997), requires EPA to identify and assess environmental health and safety risks that may disproportionately affect children. This type of analysis is required for rules that will have an impact of $100 million or more only. The impact of this SNUR will be less than $100 million and therefore no analysis of such impacts on children is required. 

### 6.7 **Executive Order 13175, Tribal Governments** Executive Order 13175 is Consultation and Coordination with Indian Tribal Governments (59 FR 22951, November 6, 2000). This rule does not have Tribal implications because EPA has no information to indicate that any tribal government manufactures or processes the chemical substances covered by this action. 

### 6.8 **Executive Order 13211, Energy Supply, Distributio**  **n, or Use** 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. 

### 6.9 **Executive Order 13563, Improving Regulation and Regulatory**  **Rev iew**  Executive Order 13563, Improving Regulation and Regulatory Review (76 FR 3821, January 21, 2011), requires EPA to base regulations on the best available science, allow for public participation and the open exchange of ideas, promote predictability and reduce uncertainty , identify and use the best, most innovative, and l east burdensome tools for achieving regulatory ends, consider both the costs and benefits qualitatively and quantitatively and ensure regulations are accessible, consistent, written in plain language, and easy to understand. The rule establishes reporting and recordkeeping requirements that apply to manufacturers (including importers) and processors of certain chemicals. Consistent with EO 13563, this document qualitatively and quantitatively describes both the costs and benefits of the rule as well as the underlying data used in the analyses. EPA chose the best available data to analyze the costs and benefits described in this document and the best analytic approaches given the available data and other constraints .**SNUR EA for PFAS**  **and Long Chain**  **PFAC in**  **Carpets Contract #**  **EP -** **W -** **08 -**  **010**

### Ap **pendix A**  **– Inflators and**  **Wage Rates** This appendix describes the derivation of the fully loaded labor rates and inflation factors used in calculating costs of labor, materials, and other inputs. Costs presented in this report are in 201 1 dollars . 

### A. **1 Derivation of Loaded Wage Rates**  Unit labor costs are calculated by adding fringe benefits and overhead to the wage or salary to derive a fully loaded labor cost. The basic method is described in Wage Rates for Economic Analysis of the Toxics Release Inventory Program (EPA, 2002b). The resulting l oaded labor rates are given in Exhibit 7 - 1 . Costs are calculated for several labor categories: Managerial, Professional/Technical, Clerical, and EPA staff. In March 2004, BLS began using the North American Industry Classification Sys tem (NAICS) codes instead of the Standard Industrial Classification (SIC) System, and the Standard Occupational Classification (SOC) system instead of the Occupational Classification System (OCS). The following table shows the crosswalk between old and new occupational titles. **EPAB Reports Labor Category**  **BLS Old Title (OCS) BLS New Title (SOC)**  Managerial Executive, administrative, and managerial Management, business, and financial Professional/Technical Professional specialty and technical Professional and related Clerical Administrative support, including clerical Office and administrative support **Source:** Employer Costs for Employee Compensation: Changes to NAICS and SOC, Table 2 . ECEC Occupational Comparability between SOC and OCS (BLS, 2006a and We instein, 2004). **A. 1.1**  **Derivation of Labor Rates for Managerial, Professional/Technical, and Clerical**  **Labor** Wages and fringe benefits for managerial, professional/technical, and clerical labor were taken from the Bureau of Labor Statistics (BLS) Employer Costs for Employee Compensation (ECEC) data, 18 for December 2012 , for manufacturing industries. 19 The cost of fringe benefits such as paid leave and insurance, specific to each labor category, are taken from the same ECEC series. Fringe benefits as a percent of wages are calculated separately for each

18 This follows the approach introduced in Economic Analysis of Expedited Significant New Use Rules for 65 Chemical Substances: EPA Docket OPPT
-2003
- 0063 (EPAB, 2007b ) . 19 Employer Costs for Employee Compensation Supplementary Tables December 2012 . (BLS, 2013 a) . This follows the approach introduced in EPAB, 2007a. Earlier PMN SNUR economic analyses, such as EP A, 2003 , used ECEC data for “All Goods Producing” sectors (manufacturing, mining, and construction) . However, the manufacturing sector data seem more relevant since the SNURs mainly affect the chemicals industry.**SNUR EA for PFAS**  **and Long Chain**  **PFAC in**  **Carpets Contract #**  **EP -** **W -** **08 -**  **010**

**▌ pg.**  **A -** **2** labor category. For example, for December 2012 , the average wage rate for professional/technical20 labor was $ 38.53 ; the average fringe benefit was $ 19.30 . Fringe benefits as a percent of wages were $ 19. 30/$ 38.53 , or approximately 50.09 percent An additional loading factor of 17 percent is applied to wages to account for overhead. This approach is used for consistency with Office of Pollution Prevention and Toxics economic analyses for two maj or rulemakings: Wage Rates for Economic Analyses of the Toxics Release Inventory Program (EPA, 2002b), and the Revised Economic Analysis for the Amended Inventory Update Rule: Final Report (EPA, 2002a). This overhead loading factor is added to the benefits loading factor, and the total is then applied to the base wage to derive the fully loaded wage. For example, the December 2012 fully loaded wage for professional/technical labor is $ 38.53 × (1+ 0.5009 + 0.17) = $ 64.38 . . Fully loaded costs for managerial and clerical l abor are calculated in a similar manner, as shown in Exhibit 7 - 1 . **A. 1.2**  **Derivation of Labor Rates for EPA Staff**  Agency labor costs are calculated based on annual Federal salaries for the Washington -Baltimore area published by the Office of Personnel Management effective January 201 2 (OPM, 201 2 ). The average salary for one FTE staff member is estimated as the salary for a GS - 13 Step 5 employee. 21 Multiplying the annual pay by an assumed loading factor of 1.6 to reflect Federal fringe benefits and overhead, the loaded annual salary of EPA staff was calculated to be $161,446. The Agency loading factor is from an EPA guide, Instructions for Preparing Information Collection Requests (ICRs) (EPA, 1992, page 30, footnote 9). The 60 percent assumption was labeled “the benefits multiplication factor” in the EPA Guide, but has been used in many EPA Office of Pollution Preventi on and Toxics ICRs to reflect both fringe benefits and overhead for Federal staff. For example, it was used in an August 2000 document supporting ICR No. 1139.06 (EPA, 2000), with the following explanation: The annual costs per FTE are derived by multiplying the annual pay rate by 1.6 (the benefits multiplication factor). The multiplication factor used is recommended in EPA’s Office of Policy, Planning, and Evaluation’s Instructions for Preparing Information Collection Requests (ICRs) (June 1, 1992). An EPA internal phone call between Carol Rawie (OPPT/EETD/RIB) and Carl Koch (OPPE/RMD/IMB) on May 3, 1994, indicated that the 1.6 factor included not o nly benefits but also overhead. (ICR No.1139.06)

20 This follows terminology introduced in EPAB, 2007 b . Earlier SNUR economic analyses used the term “technical” labor. Here the category is called “professional/technical” labor, to make clear how it relates to BLS categories . In 2004, BLS changed from the Occupational Classification System, OCS, to the Standard Occupational Classification system, SOC . In the process, the “Professional specialty and technical” category became the “Professional and related” category . However, the coverage of the old and new occupational groups is approximately the same . See the BLS article, C omparing Current and Former Industry and Occupation ECEC Series (Weinstein, 2004). 21 The GS - 13 Step 5 is consistent with ICR No. 0 574.14 (12/18/2007), which covers PMN SNURs. Use of this grade level follows the approach introduced in EPAB, 2007a. That report represented a change from the earlier PMN SNUR economic analysis (EPA, 2003), which used an average of GS - 12 Step 1 and GS - 12 Step 10 salaries.**SNUR EA for PFAS**  **and Long Chain**  **PFAC in Carpets**  **Contract # EP**  **- W**  **- 08**  **- 010**

### A. **2 Derivation of Inflation Factors**  Detailed information on the derivation of the inflation factors used is presented in Exhibit 7 - 2 . In 2006, the Bureau of Labor Statistics (BLS) made several changes to the Employment Cost Index. The changes are described on a BLS web page, “Change has come to the ECI,” (BLS, 2006c ) and in several April 2006 Monthly Labor Review articles posted on the BLS web site: “Changes affecting the Employment Cost Index: an overview” (Caroll , 2006 ); “Employment Cost Index Publication Plans” ( Sleemi, 2006 ); and “Seasonal adjustment in the ECI and the conversion to NAICS and SOC” ( Branch, 2006 ). Under a mandate from OMB, BLS changed its classification of industries and occupations from the Standard Industrial Classification (SIC) and Occupational Classification System (OCS) to the North American Industry Classification System (NAICS) and Standard Occupational Classification (SOC) system. In 2006, BLS adjusted all ECI series to reflect this change. In addition to changing the industry and occupational classification systems, in 2006, BLS rebased the ECI from June 1989 = 100 to December 2005 = 100 for all current and historical non- seasonally adjusted series, including the NAICS and SIC based series. (Seasonally adjusted indices, including those in Exhibit 7 - 2 of this report, may not exactly equal 100 for December 2005 as a result of the seasonal adjustment. Seasonal adjustments are explained in Branch, 2006.) According to BLS, the official ECI for the years 1975 - 2005 is the SIC - OCS based series, and for subsequent years, the official ECI is the NAICS - SOC based series (Sleemi, 2006, p.8). 22 “Starting year” indices in Exhibit 7 - 2 continue to be SIC - OCS based. Current year indices are NAICS - SOC based. We use indices from both the NAICS - SOC and the SIC - OCS based ECI series because neither series spans the entire period over which testing and other costs need to be inflated.

22 BLS has been publishing the NAICS - SOC based ECI series since March 2001 and it became official in March 2006. The SIC - OCS based series and NAICS - SOC series have different series ID numbers, even when they describe essentially the same population. For example the series ID for seasonally adjusted total compensation for all private industry workers is ECS10002I for the SIC - OCS series and CIS2010000000000I for the NAICS - SOC series .**SNUR EA for PFAS**  **and Long Chain**  **PFAC in Carpets**  **Contract # EP**  **- W**  **- 08**  **- 010**

The Consumer Price Index (CPI) was not rebased. “Starting year” ECI indices are SIC - OCS based: Seasonally Adjusted (SA) ECS10002I for private industry All Workers, and not SA ECU11122I for private i ndustry Professional and Related Workers. After 2006, ECI indices are NAICS - SOC based: Seasonally Adjusted (SA) CIS2010000000000I for private industry All Workers, an d not SA CIU2010000120000I (B) for private industry Professional, and Related workers. 2 Inflation factors are rounded ; however , unrounded values were used in calculations . 3 B eginning with the report Economic Analysis of Expedited Significant New Use Rules for 25 Chemical Substances: EPA Docket OPPT2009 - 0922 (EPA, 2011b) we began to use the not -seasonally adjusted CIU2010000120000I for private industry Professional, and Related workers, instead of SA CIS2010000W00000I for private industry white collar workers because BLS retired the “whit e - collar” series.
