## Executive Summary This report estimates the costs of a Significant New Use Rule (SNUR) being proposed by the U.S. Environmental Protection Agency (EPA) for toluene diisocyanate (TDI) and related compounds . The proposed rule will apply to the seven chemicals listed in Table ES - 1 : Toluene Diisocyanate Related Compounds Subject to this Action with a Proposed Significant New Use of “Any Use in a Consumer Product” and Table ES - 2 below. **Table ES -**  **1 :**  **Toluene Diisocyanate Related Compounds Subject to this Action with a Proposed Significant New Use of “Any Use in a Consumer Product”**  **Chemical Name**  **Chemical Abstracts Index Nam e**  **Chemical Abstract Service Registry**  **Number (CASRN)** Toluene diisocyanate trimer Benzene, 1,3 - diisocyanatomethyl - , trimer 9019 - 85 - 6 Poly(toluene diisocyanate) Benzene, 1,3 - diisocyanatomethyl - , homopolymer 9017 - 01 - 0 Toluene diisocyanate dimer 1,3 - Diazetidine - 2,4 - dione, 1,3 bis(3 - isocyanatomethylphenyl) - 26747 - 90 - 0 Tolulene diisocyanate “cyclic” trimer 1,3,5 - Triazine - 2,4,6(1H,3H,5H) trione, 1,3,5 - tris(3 isocyanatomethylphenyl) - 26603 - 40 - 7 **Table ES -**  **2 :**  **Toluene Diisocyanates Subject to this Action with a Proposed Significant Use of**  **“Any Use in A Consumer Product (Except for Use**  **in Coatings, Adhesives**  **, Elastomers, Binders, and Sealants at Less than or Equal to 0.1 Percent in a Consumer Prod**  **uct )**  **” Chemical Name**  **Chemical Abstracts Index Nam e**  **Chemical Abstract Service Registry**  **Number (CASRN)** 2,6 - Toluene diisocyanate Benzene, 1,3 - diisocyanato - 2 - methyl - 91 - 08 - 7 2,4 - Toluene diisocyanate Benzene, 2,4 - diisocyanato - 1 - methyl - 584 - 84 - 9 Toluene diisocyanate unspecified isomer Benzene, 1,3 - diisocyanatomethyl - 26471 - 62 - 5 EPA is proposing a significant new use rule (SNUR) under the Toxic Substance Control Act (TSCA) section 5(a)(2) for 2,4 -toluene diisocyanate, 2,6 -toluene diisocyanate, toluene diisocyanate unspecified isomers (these three chemical substances are hereafter referred to as toluene diisocyanates or TDI) and related compounds (toluene diisocyanate trimer, poly(toluene diisocyanate), toluene diisocyanate dimer, and toluene diisocyanate cyclic trimer). The proposed significant new use is any use in a consumer product of the chemical substances listed in Table ES - 1 or any use in a consumer product of any chemical listed in Table ES - 2 other than use in coatings, elastomers, adhesives, binders, and sealants that results in less than or equal to 0.1 percent by weight of TDI in a consumer product. For this proposed rule, the general SNUR article exemption for persons who import or process chemical substances listed in Table ES - 1 and ES - 2 as part of an article would not apply. The article exemption at 40 CFR 721.45(f ) is based on an assumption that people and the environment will generally not be exposed to chemical substances in articles (see 49 FR 35014; September 5, 1984). However, TDI and related compounds are volatile and as such could migrate out of articles that contain them. For instance, studies of TDI in polyurethane products reported that after the reaction between an isocyanate and an alcohol to form polyurethane products, residual levels of isocyanates were detected on the surface of the products, which if used could lead to exposure (Krone, 2004; Bello et. al, 2007 ) . Because TDIiii

and related compounds are known to be volatile chemical substances, have been reported to mi grate from products, and are sensitizers, EPA would like the opportunity to evaluate such potential uses in consumer products for any associated risks or hazards that might exist before those uses would begin . Consumer products are often marketed as do - it -yourself (DIY) products and as a result consumers would be unaware of the potential hazards of consumer products, including articles containing TDI or other diisocyanates. Consequently, insufficient and inadequate hazard communication may lead to incorrect use and increased consumer and bystander exposures , particularly for sensitive groups, such as children. The proposed SNUR requires manufacturers, importers, or processors of the seven chemicals to notify EPA at least 90 days prior to the occurrence of any significant new use. A firm intending to engage in these activities would be required to submit a Significant New Use Notice (SNUN), incurring an estimated submission cost of $8,5 89 per chemical, and potentially other minor costs , such as export notification and consumer notifi cation 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 that activity before it occurs. In addition to any firms that may make a SNUN submission, the proposed 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 are estimated at the firm level and reflect the burden of a SNUR on the firms that make a submission . The hidden costs to the firms that do not make a submission are not quantified. EPA receives fewer than ten SNUNs per year. The number of firms affected by not making submissions to EPA is not known; therefore, costs are not aggregated across the affecte d entities.iv

## 1 **Introduction** This report estimates the costs of the proposed Significant New Use Rule (SNUR) for seven toluene diisocyanate (TDI) chemicals and related compounds : ( 1) T oluene diisocyanate, ( 2) T oluene diisocyanate trimer, ( 3) 2,6 - T oluene diisocyanate, ( 4) 2,4 - T oluene diisocyanate, ( 5) P oly(toluene diisocyanate), ( 6) Toluene diisocyanate dimer, and ( 7) Toluene diis ocyanate “cyclic” trimer. The CAS RN and common names of these chemicals are found in Table 1 and Table 2 below . **Table 1**  **: Toluene Diisocyanate Related Com**  **pounds Subject to this Action with a Proposed Significant New Use of “Any Use in a Consumer Product”**  **Chemical Name Chemical Abstracts Index Nam** **e Chemical Abstract**  **Service Registry Number (CASRN)**  Toluene diisocyanate trimer Benzene, 1,3 - diisocyanatomethyl - , trimer 9019 - 85 - 6 Poly(toluene diisocyanate) Benzene, 1,3 - diisocyanatomethyl - , homopolymer 9017 - 01 - 0 Toluene diisocyanate dimer 1,3 - Diazetidine - 2,4 - dione, 1,3 bis(3 - isocyanatomethylphenyl) - 26747 - 90 - 0 Tolulene diisocyanate “cyclic” trimer 1,3,5 - Triazine - 2,4,6(1H,3H,5H) trione, 1,3,5 - tris(3 isocyanatomethylphenyl) - 26603 - 40 - 7 **Table 2**  **: Toluene Diisocyanates Subject to this Action with a Proposed Significant Use of “Any**  **Use in a Consumer Product (Excep**  **t f or**  **Use in Coatings, Adhesives, Elastomers, Binders, and Sealants at Less than or Equal to 0.1 Percent in a Consumer Product** **) ”**  **Chemical Name Chemical Abstracts Index Nam** **e Chemical Abstract**  **Service Registry Number (CASRN)**  2,6 - Toluene diisocyanate Benzene, 1,3 - diisocyanato - 2 - methyl - 91 - 08 - 7 2,4 - Toluene diisocyanate Benzene, 2,4 - diisocyanato - 1 - methyl - 584 - 84 - 9 Toluene diisocyanate unspecified isomer Benzene, 1,3 - diisocyanatomethyl - 26471 - 62 - 5 TDI and its related polyisocyanates are generally supplied by their manufacturers as raw materials to formulators who take advantage of the diisocyanates’ chemistry to combine them with other chemicals and create different polyurethanes with a wide variety of applications ( EPA, 2011 ). The chemicals are commonly available in unreacted forms as part of product mixtures, and are widely used in construction, automotive, and other similar applications that require an end-use reaction as part of the functional performance of a product (EPA, 2011 ). Diisocyanate s are well -known dermal and inhalation sensitizers in the workplace and have been documented to cause asthma, lung damage, and , in severe cases, fatal reactions ( EPA, 2011 ). In the past, consumer exposures have not been a focus of concern with respect to diisocyanates, because of the assumption that consumers were generally exposed to products containing only cured polyurethanes, which are generally considered to be inert and non-toxic (Krone and Klinger, 2005). However, an increase in consumer availability of , or exposure to , polyurethane products intended to further react and undergo “curing” has occurred in the marketplace ( EPA, 2011 ). For example, products, such as coatings, elastomers, adhesives, and sealants , may contain TDI compounds that are not comp letely reacted when applied and can provide potential exposures to the consumer (Krone, 2004; Bello et. al, 2007). The 20 12 Chemical Data Reporting (CDR) database indicates that TDI chemicals are used in the following consumer or commercial categories : ( 1) adhesives and sealants, (2) paints and coatings, and ( 3) foam seating and bedding products (EPA, 2013). Consumer products are often marketed7

as do - it -yourself (DIY) products and as a result consumers would be unaware of the potential hazards of consumer products, including articles containing TDI or other diisocyanates. Consequently, insufficient and inadequate hazard communication may lead to incorrect use and increased consumer and bystander exposures, particularly for sensitive groups, such as children 

### . EPA believes that the use of any of these chemicals substances beyond the limited ongoing uses could significantly increase the magnitude and duration of exposure to TDI and that such an increa se should not occur without an opportunity for EPA to review. The proposed SNUR requires manufacturers, importers, or processors of the seven chemicals to notify EPA at least 90 days prior to the occurrence of any significant new use. A firm intending to engage in these activities would be required to submit a Significant New Use Notice (SNUN). The required notification allows EPA to evaluate the intended use and, if necessary, to prevent or limit the potential consumer and general population health affect s that may result from exposures to uncured TDI and related compounds . For this proposed rule, the general SNUR article exemption for persons who import or process chemical substances listed in Table 1 and 2 as part of an article would not apply. The arti cle exemption at 40 CFR 721.45(f ) is based on an assumption that people and the environment will generally not be exposed to chemical substances in articles (see 49 FR 35014; September 5, 1984). However, TDI and related compounds are volatile and as such c ould migrate out of articles that contain them. For instance, studies of TDI in polyurethane products reported that after the reaction between an isocyanate and an alcohol to form polyurethane products, residual levels of isocyanates were detected on the surface of the products, which if used could lead to exposure (Krone, 2004; Bello et. al, 2007) . Because TDI and related compounds are known to be volatile chemical substances, have been reported to migrate from products, and are sensitizers, EPA would like the opportunity to evaluate such potential uses in consumer products for any associated risks or hazards that mi ght exist before those uses would begin . . 

### 1.1 **Statutory Au**  **thority and**  **Significant New Uses under the Proposed SNUR**  Section 5(a)(2) of TSCA (1 5 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, 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. 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 su bstance’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 proposing to define the significant new use as any use in a consumer product of the chemical substances listed in Table ES - 1 or any use in a consumer product of the chemical substances listed in8

Table ES - 2, except for use in coatings, elastomers, adhesives, binders, and sealants that results in less than or equal to 0.1 percent weight of TDI in a consumer product. Consumer products, in general, are products readily available for purchase by the consumer . A company would be expected to submit a SNUN for any of the seven chemicals included in the propos ed SNUR prior to initiating a new use. 

### 1.2 **Summary**

**of Methodology** This analysis quantifies, to the extent possible, the costs to society of the proposed rule by identifying the costs to industry associated with performing the required reporting and recordkeep ing, 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 to produce an estimate of the universe of affected entities and measure the impact of the proposed rule on small entities. In addition to costs, t

his report qualitatively discusses the benefits of the proposed rule based on the value of the information it will provide. The benefits analysis was undertaken to address the implicit call for cost -benefit balancing contained in TSCA , as well as the requirements of Executive Order 12866. 

### 1.3 **Organization of this Report** The remainder of this report provides EPA’s economic analysis in support of the proposed rule. Chapter 

### 2 present s estimates of the industry costs to comply with the proposed rule, and Chapter 

### 3 provides estimates of the government costs associated with the administration of the proposed rule. Chapter 

### 4 addresses the benefits of the proposed rule. Several additional impact analyses are presented in Chapter 

### 5 , 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 implicati ons that addresses the requirements of Executive Order 12898 ; and a n analysis of children’s health pertinent to Executive Order 13045 . Note that all dollar amounts in this analysis are reported in 20 12 dollars.9 

## 2 **Industry**

**Compliance Costs** The proposed SNUR discussed in this report specifies that any manufacture, import, or processing of the chemicals or the importation or processing of an article for a designated significant new use will require reporting under section 5(a)(1)(A) of TSCA . There fore, a firm intending to manufacture, import, and/or process any of these chemical s for these applications must submit a SNUN . Alternatively, a firm can decide not to manufacture, import, and/or process the s e chemical s or to manufacture, 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, import, and/or process the chemical or the import or process an article for a significant new use, which, in this case, means use in a consumer product of the chemical substances listed in Table ES - 1 or any use in a consumer product of the chemical substances listed in Table ES - 2 , except for use in coatings, elastomers, adhesives, binders, and sealants that results in less than or equal to 0.1 percent weight of TDI in a consumer product. The firm must submit the SNUN to EPA at least 90 days before it plans to commence the manufacture, 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, import, and/or processing of any o f the seven chemicals 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 2.2.8 for details).

 **Option 2**  **: Comply with SNUR limits (**  **not manufacture, 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 , importing, and/or processing , or importing or processing as part of an article , any of the seven listed chemicals in a manner such that they would be considered significant new uses . That is, if the firm does not use any uncured TDI and related compounds in a consumer product it would 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 provided 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 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 proposed SNUR for these uses of the subject chemicals . Section 2.1 summarize s the wage rates used in this chapter . Section 2.2 provides the unit industry compliance costs , including the costs of rule familiarization, registration with the Central Data Exchange (CDX) electronic reporting tool , completing the SNUN form , submission fee , import certification, and export notification . Section 2.3 discusses the implications and potential compliance costs associated with removing the general SNUR article exemption for persons who import or process 2,4 -toluene diisocyanate, 2,6 -toluene diisocyanate, toluene diisocyanate unspecified isomers and related chemical substances as part of an article. Total costs under each option are presented in Sectio n 2.4 .1 0



### 2.1 **Wage Rates**  The proposed 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 multip lying those burdens by the wage rate for each 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 benef

its with estimates of overhead rates, following the methodology described in Wage Rates for Economic Analysis of the Toxics Release Inventory Program (EPA, 2002b) . Wage data for each labor category in December 201 2 are provided by the Employer Costs for Em ployee Compensation (ECEC) Supplemental Tables available on the BLS website (BLS, 201 3 a). The loaded wage rate is $ 72.84 for managerial labor; $ 64.38 for technical labor; and $ 29.81 for clerical labor. Table 3 presents the basic data used to calculate the loaded wage rates for all three categories of labor. Appendix A: provides more information on the wage rates and inflators used in this analysis. **Table 3**  **: Loaded Industry Wage Rates, December 2012**  **Labor Category**  **Data Sources Date**  **Wa ge**  **( 201**  **2 $)**  **Fringe**

### 2.2 **Unit Industry**

**Compliance Costs 2.2.1**  **Rule Familiarization** The proposed 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 of11

SNUNs and other TSCA Section 5 notices. As shown in Table 4 , the total labor cost associated with rule familiarization is $ 54.84 . **Table 4**  **: Rule Familiarization Burden and Cost for SNUR Submitters**  **Reporting Activity Clerical Lab**  **or (at**  **$29. 51**  **/hour) Technical Labor (at**

Unrounded estimates were used during the actual cost calculations. **Source:** Se e Table 3 ; EP A, 2009a . **2.2.2 CDX Registration, CDX Electronic Signature, and Pay.gov A** **ccount Setup** The proposed SNUR requires first- time submitters of any TSCA section 5 notice (including Premanufacture Notices ( PMNs), Significant New Use Notices (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 S ection 5 notices ) 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. 1 These activities are only required of first -time submitters of any S ection 5 notice . These activities are estimated to require the following burdens, 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 may be done either through mail or electronically. EPA believes the cost of electronic filing to be negligible, while the cost of mailing in the agreement for verification will involve extra costs. For this economic analysis, EPA has conservatively chosen to consider the cost of paper filing via the US Postal Service. This cost is estimated to be $2.60 per company (including five $0.46 stamps 2 and five $0.06 business envelopes 3 ).

1 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. 2 Price for a stamp was taken from the U.S. Postal Service website on April 9, 2013. (See USPS, 2013a)12

 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 Table 5 , the labor cost associated with CDX registration, CDX electronic signature, and Pay.gov account setup by a first -time submitter is $ 189. As noted above, an additional $2.30 in mailing cost per company is attributable to these activities, for a total cost of approximately $ 1 92 per company. **Table 5**  **: CDX Registration, CDX Electronic Signature, and Pay.gov Account Setup Burden and**  **Cost for First -**  **Time Submitters Reporting Activity**  **Clerical Labor (at $29.**  **51 /hour)**  **Technical Labor**

Unrounded estimates were used during the actual cost calculations. **Source:** See Table 3 ; EP A, 2009a . **2.2.3 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 proposed 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 Amen dments 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 1 1 - 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 submission of all TSCA section 5 notices. Electronic submission of SNUN forms is expected to remove all clerical burden and reduce the recordkeeping burden associated with preparing a SNUN (EPA, 2009 a) . 4 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 7 3 . 68 hours of technical labor and 18.00 hours of managerial labor (EPA, 2009a).

bines the estimated reporting burden and lo aded 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 $ 6,089 . **Table 6**  **: Industry Cost Estimate to Complete the SNUN**  **Form Reporting**  **Activity Clerical Labor (at**

Unrounded estimates were used during the actual cost calculations. **Source** : Loaded wages include fringe benefits and overhead . See Table 3 of this report for derivation . Wage rates presented in this table are rounded values; however, unrounded values are used to calculate total lab or costs . For this reason, total labor costs may not equal the product of rounded values. The estimate of no clerical burden is taken from the Economic Analysis of the Premanufacture Notice Electronic Reporting Final Rule (EPA, 2009a, page 7) . 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 El ectronic SNUN form (EPA, 2009a page 15). 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. Table 7 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. **Table 7**  **: Industry Cost Estimate to Complete and Submit the SNUN Form**

4 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 technic al labor were removed. It is im portant to note that for this analysis, clerical burden changes 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. .14

**2.2.4 Recordkeeping**  **for Companies Choosing to Submit a SNUN** Companies submitting a SNUN must , under 40 CFR §721.40 , keep records of the information contained in the SNUN . Some EPA reports have assumed that SNUN recordkeeping hours would be five percent of SNUN submission hours, or about five to six hours. 5 For this report, the SNUN recordkeeping hours were included in the SNUN submission hours (see Section 2.2.3 ) and the SNUN recordkeeping costs under 40 CFR §721.40 were not separately estimated. 6 **2.2.5 Recordkeeping for Companies that do not Submit a SNUN**  If a firm that manufactures, imports, or processes a substance subject to the proposed 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 category of use 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 total recordkeeping burden for a company that does not submit a SNUN is estimated to be 0. 15 hours and $ 9 .66 , and is derived in Table 8 . **Table 8**  **: Annual Per**  **- Chemical Costs of Recordkeeping Requirement for Companies that**  **Choose not to Submit a SNUN**  **Reporting Activity Total Burden**  **Associated per Activity**  **(Hours) Percent of** 

**Reporting Burden Attributed to**  **Recordkeeping Recordkeeping Burden**  **(hours) (** **201 2**  **$)** Category of use 1 3 5% **0.15 $9.**  **66 Source:**  1 US EPA, 2005 b Office of Pollution Prevention and Toxics Information Collection Request (ICR) for TSCA Section 5(a)(2) Significant New Use Rules for Existing Chemicals (Renewal) (page 13 ) **2.2.6 Customer Notification**  Manufacturers, processors, and importers of chemicals subj ect to SNURs must notify recipients of such chemicals of the SNUR or verify that knowledge of the SNUR has been otherwise acquired by recipients,

5 For example, OPPT’s Information Collection Request (ICR) for TSCA Section 5(a)(2) Significant New Use Rules for Existing Chemicals (Renewal), October 11, 2 005, estimates SNUN recordkeeping costs at 5.67 hours (ICR 118.08, page 1 5 ). 6 SNUN submission costs estimated in Section 2.2.3 of this report were based on PMN submission costs from a 1994 report, Regulatory Impact Analysis of Amendments to Regulations for TSC Section 5 Premanufacture Notifications (EPA, 1994). Page III - 14 of the 1994 report refers to “the normal records kept with a PMN submission which are included in the estimates for submission costs.” Page III - 12 identifies “maintaining a file of the submission” as part of the labor hours for the PMN reporting form. These statements imply that the 95 to 114 total hours for a PMN submission (page III - 10 of EPA 1994) included recordkeeping hours.15

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, processors, and importers 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 manufacturer, processor, or importer per chemical. The proposed SNUR will cover a total of seven chemicals . **2.2.7 Import Certification**  In general, promulgation of a final 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, importer, or processor receiving an imported shipment of chemicals subject to the proposed SNUR would 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. 7 The statement must be on or attached to a commercial invoice or entry document belonging to the imported shipment. In practice, import certification is fulfilled by checking a box on an invoice or entry document and generally imposes no additional burden or cost on the importer (EPA, 2009 c ). Any potential burden associated with a submitter’s familiarization with this requirement is assumed to be included in the more general SNUR familiarization burden discussed above. **2.2.8 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 8 per destination country for each exporter of a chemical substance . After receiving a notification from a firm, EPA notifies the importing country and the 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 single 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 vari ety of unrelated uses, manufacturer 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 [Information Collection Request for] Notification of Chemical Exports - TSCA Section 12(b) Supporting 7 The exact statements are as follows: For imports of chemical substances subject to TSCA, “I certify that all chemical su

bstances 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 im ports of chemical substances not subject to TS CA (e.g., pesticides), “I certify that all chemicals in this shipment are not subject to TSCA.” ( 40 CFR 707.20 ) 8 On November 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).16

Statement for Request for OMB Review under the Paperwork Reduction Act (EPA, 2009b), with updating for infl ation . **Estimated Number of Annual Export Notifications per Exporter** EPA’s 2009 TSCA Section 12(b) ICR estimated that the average exporter making notifications will make 12 notifications per year. 9 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 proposed 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. 10 The percent of notifications resulting from S NURs 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. **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 (USPS) as first - class registered mail with a return receipt (USPS, 201 3b ) . The estimated per- shipment and annual mailing costs incurred by individual submitters are detailed in Table 9 .

9 EPA calculated the average num ber of export notifications per exporter in the 2009 TSCA Section 12(b) ICR (EPA, 2009b) by dividing the estimate d number of submitted notifications (3,500) by the estimated number of exporters (300 ). 10 Based on review

by an EPA economist of notifications received under TSCA Sections 4, 5 and 6 over approximately three weeks in early 2010.17

**Table 9**  **: Derivat** **ion 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 $**  **171 Source:**  Mailing rates are from the US Postal Service web site as of April 201 2 (http://www.usps.com/prices/) . The mailing method comes from the 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). **Note:** Calculations may be rounded. **Compile 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 there would be approximately 300 submitters per year in near- future years (EPA, 2009b ) . Of these 300 submitters, EPA estimated that 2 00 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 TSCA §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 time period . This process is estimated to take an average one half hour of clerical time per export notification or six hours for 12 notifications (EPA, 2009b) . The burdens and associated costs for each notification activity are provided in Table 10 . EPA estimates that the burden associated with making one notification is approximately 1.36 hours and $ 84.22 .18

### 2.3 **Ar ticle Importation and Processing**  The proposed SNUR contains a provision to eliminate the exemption for the importation or process ing of consumer articles containing T DI and related compounds. This will require importers and processors of consumer articles containing TDI and related compounds to notify EPA at least 90 days before importing or processing consumer articles containing chemicals subject to the proposed rule. In addition, the rule may also affect firms that do not currently import or process articles containing the chemicals, but who may be interested in importing or processing these articles in the future or who may be interested in ensuring that the articles they import or process 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. 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” 11 and importers are responsible parties under the proposed 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. **2.3.1 Af** 

**fected Entities** SNUR reporting requirements for persons who may process articles containing chemicals substances subject to the SNUR are similarly described in § 40 CFR 721.5; however, the reporting requirements for processors (including processors of articles containing subject chemicals) are specifically limited. As described in § 40 CFR 721.5(c), a processor is not required to submit a SNUN if he can document that (1) he does not know the specific chemical identity of the chemical substance being processed; and (2) that he is processing the chemical substance without knowledge that the substance is subject to a SNUR. This analysis focuses on the s tandard business practices that a processor would already undertake that would serve to document compliance with the rule. Table 1 1 contains example NAICS codes for firms that may import or process consumer articles containing TDI or its related compounds . Articles may include products such as paints, adhesives, and foam products. This is not meant to be an exhaustive list, but rather an example of the types of industries

11 TSCA section 3(7).19

that may be impacted by the articles exemption. As shown in Table 1 1 , a wide variety of industries may import consumer articles containing TDI or its related compounds . **Table 11**  **: Examples of Industries that may Import**  **or Process Articles Containing TDI**  **NAICS Code**  **Section Description**  326 Plastics and Rubber

Products Manufacturing Industries in the Plastics and Rubber Products Manufacturing subsector make goods by processing

plastics materials and raw rubber . Many manufacturing activities use plastics or rubber, for example the manufacture of footware, or furniture. 423 Merchant

Wholesalers, Durable Goods Industries in the Merchant Wholesalers, Durable Goods subsector sell capital or durable goods to other

businesses. Durable goods are new or used items generally with a normal life expectancy of three years or more. Durable goods merchant wholesale trade establishments are engaged in wholesaling products, such as motor vehicles, furniture, construction materials, machinery and equipment (including household - ty

pe appliances), metals and minerals (except petrol eum), sporting goods, toys and hobby goods, recyclable materials, and parts. 424 Merchant

Wholesalers, Nondurable Goods Industries in the Merchant Wholesalers, Nondurable Goods subsector sell nondurable goods to other

businesses. Nondurable goods are items generally with a normal life expectancy of less than three years. Nondurable goods merchant wholesale trade establishments are engaged in wholesaling products, such as paper and paper products, chemicals and chemical products, drugs, textiles and textile products, apparel, footwear, groceries, farm products, petroleum and petroleum products, alcoholic beverages, books, magazines, newspapers, flowers and nursery stock, and tobacco products. 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 showrooms and have substantial areas for the presentation of their products. 450 General

Merchandise Stores Industries in the General Merchandise Stores subsector retail new general merchandise from fixed

point- of - sale locations. Establishments in this subsector are unique in that they have the equipment and staff capable of retailing a large variety of goods from a single location. This includes a variety of display equipment and staff trained to provide information on many lines of products. **2.3.2 Potential Compliance A** **ctivities (A rticle Importers)**  Given the existing regulatory limitations on certain chemicals both internationally and within the U.S., certain regulated industries have begun to develop industry-wide processes and other resources to support companies that are interested in understanding and managing their supply chains. Because the rule would not prescribe the 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 content of articles, organize declarations from suppliers, or certify suppliers based on materials or processes used. Importers (or processors) 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 Assessm ent of Materials and Products for Declarable Substances (“ASTM F2577”) which provides guidance for the decision process to assess materials and products for declarable substances. Based on ASTM F2577, the following list includes activities that an importer could perform to identify any restricted chemicals in imported articles. This list is intended to capture the general types of activities that might be performed.20

**1) Understand applicable requirements (Per Firm Cost).**  The importer would need to read and understand the SNUR, within the context of the company’s products. This burden is as derived in Section 2.2.1 of this report. **2) I**  **dentify the type of imported articles that potentially contain the restricted substances (Per Firm Cost).**  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 a re imported, and as necessary, make 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 from 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. Table 12 contains the cost ranges associated with the above activities. The activities and cost derivations are discussed in more detail in Understanding the Costs Associated with Eliminating Exemptions for Articles in SNURs (EPA, Not Yet Published).**12 :**  **Range of Costs Associated with an Importer’s Identification of Chemicals Subject**

This cost would particularly be associated with companies that have no previous experience complying with chemical restriction rules; companies that already have methods in place to identify chemicals in articles likely already have recordkeeping systems in place **Related Costs** Collect data from suppliers $5 to $5 15 per article reviewed. $0 if no data collected. Actual costs only apply to those companies that choose to collect data from

suppliers. They will vary depending on the specific data collection method chosen. Total costs depend on considerations including the number of articles im ported, number of suppliers, and frequency of supplier changes. Chemical testing $130 per article te sted. $0 if no testing. Actual costs only apply to those companies that choose to collect data from

suppliers. They will vary depending on the specific chemical being tested for; the complexity of the article and sample preparation required; and the exact fees of the laboratory chosen for the analysis. Total costs per company will depend on considerations including the number of articles tested, which may be affected by the number of suppliers and risk associated with each, and frequency of supplier changes .22

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 importer will fur ther depend on the number of affected articles and the frequency of supplier change. Restrictions on TDI currently do not exist under the European Union’s Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) regulations. However, th e European Commission Regulation limits TDI to 1 mg/kg in plastic products intended to come into contact with food (European Commission, 2011). Furthermore, TDI is prohibited in cosmetic products in Canada, New Zealand, and the European Union (Australian G overnment, 2013). Tolune diisocyanates unspecified isomers (CAS 26471 - 62 - 5) is placed on the California Proposition 65 list of chemicals known to cause cancer, birth defects, or other reproductive harm, and has a maximum allowable dose level of 20μg/day (O EHHA, 2013). Firms that have previously selected suppliers that have agreed to uphold certain standards, or who have otherwise sufficiently demonstrated that they are not supplying TDI -based chemicals, would not likely incur any additional costs associate d with these activities. Essentially, the product’s certification would allow importers or processors of articles to learn whether an article does or does not contain TDI or whether suppliers have agreed to uphold certain production standards. There are la beling systems for products in which independent entities ensure that the production of products does not utilize specific chemicals. For example, the European Union has developed a voluntary labeling system, called the EU Ecolabel. Producers, importers and retailers can voluntarily apply for the EU Ecolabel (EC, 2013). Labeled products signal to consumers that the product in question has a reduced environmental impact throughout the product’s life cycle, such as the manufacturing stage and/or during the final product disposal. The criteria are specifically designed to focus on the stage of the life cycle where a product has the most environmental impact (EC, 2013). Firms with less experience with other regulations that are planning to import articles that could potential ly contain TDI -based chemicals may incur a larger burden should they choose to conduct some or all of the activities listed above to ensure compliance. These firms may choose to reach out to a wide variety of upstream firms including to gath er information on the chemical content of articles, for example, through MSDSs or other documentation. Firms may also choose to conduct additional research on their suppliers to ensure that they are purchasing from reputable manufacturers and chemical supp liers who will provide necessary technical support, as well as regulatory standards (AFIRM, 2011). Furthermore, a company could choose to have articles tested. If a company chooses to conduct testing they may also need to conduct additional research to ensure the laboratory is accredited, reliable and follows Good Laboratory Practices (GLP) (AFIRM, 2011). 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 c ompany perceives, and the resources it has available. **2.3.3 Potential Compliance A** **ctivities (Processors of A rticles)**  Under § 40 CFR 721.5(a)(2), manufacturers, importers, or processors of subject chemical substances who distribute the substance in commerce must notify the recipient, in writing, of the applicability of SNUR requirements, or document that the recipient has such knowledge or will not undertake any significant new use described in the rule. Therefore, the article proc essor, as the recipient of any subject chemical substance, should receive written notification from the supplier, and would keep this documentation as part of their standard business practice.23

Should a processor need to demonstrate compliance with the SNUR, it is expected that processors would use notification from the supplier or other shipping or labeling documents (such as Material Safety Data Sheets (MSDS), etc.) received with the article in the ordinary course of business. To the extent that processors desire extra certainty that the articles they process are not subject to a SNUR, they may undertake the steps to identify regulated chemicals outlined above for importers. 

### 2.4 **Summary**

**of Per Submission Costs, by Option**  The number of firms affected by not making submissions to EPA is not known; therefore, costs are not aggregated across the affected entities . The following table summarizes the costs to comply with the proposed rule amendment, as described in more detail in section 2.2 above. **Table 13**  **: Compliance Options and Associated Costs Incurred by a Firm Due to the Proposed**  **SNUR Option**  1 **Costs Quantified Costs per Che**  **mi cal**  **( 20**  **1 2**  **$)** 2

1. Electronic submission of a Significant New Use Notice (SNUN), indicating to EPA that the firm would like to manufacture, 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, Rarely, a firm may choose to conduct toxicity or fate testing to support the SNUN, but such testing i s not required by law . 3 $ 54.84 rule familiarization cost; $8, 589 submission cost (including SNUN recordkeeping 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 will vary. First time submitters would incur $ 191.91 for CDX registration and associated activities. Companies manufacturing, importing, or processing a chemical currently used in commerce in the United States will incur a cost $ 64.38 for notifying consumers of SNUR regulatory activities .

2. Manufacture, 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 quantified 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 i dentification ($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 manufacturing, 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 2.2 . 3 EP A 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/o r describe any other available data. Because EPA does not require the development of test data, EPA assumes that no firms will incur testing costs as a result of the proposed SNUR. 

### 2.5 **Likelihood of SNUN Submission**  This analysis assumes that very few 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 four in Federal24

fiscal year (FY) 2005, eight in FY2006, six in FY2007, eight in FY2008, seven in FY2009 , two in FY2010, and ten in FY2011 12

. 

### 2.6 **Potential for Subsequent Regulatory**  **A ctions**  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 unreasonab le risk of injury to human health or the environment . Itis 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 Agency’s review of the SNUN result in further regulatory actions, the Agency will 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.

12 In-person count of SNUNs conducted by Kimberly Wilson of Abt Associates Inc , on April 8, 2010 at EPA’s Confidential Information Business Center (CBIC) and updated values for FY2010 and FY2011 provided by Lynn Blake - Hedges of US EPA on September 1, 2011 .25 

## 3 **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 . 

### 3.1 **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 ) . EPA assumes that, on average, a federal GS - 13, Step 5 full -time equival ent (FTE) will conduct its collection and administrative activities under the proposed rule. 13 The average salary for a GS - 13 Step 5 employee was $ 100,904 in 201 2 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, which results in a fully loaded annual salary of $ 161,446.40 (see Table 14 : Derivation of Loaded Agency Wage Rates ) . Dividing the fully loaded annual salary by 2,080 hours (i.e., the number of hours in a work year) yields an hourly FTE wage rate of $ 77.62 . The Agency loading factor of 1.6 is from an EPA guide entitled 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 OPPT ICRs to reflect both fringe benefits and overhead for federal staff . For example, it was used in a document supporting EPA 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 only benefits but also overhead. Fully loaded costs for Agency labor are shown in Table 14 .

13 The GS - 13 Step 5 is consistent with ICR No. 0574.14 (12/18/2007) ( EP A, 2007a), which covers PMN SNURs. Use of this grade level follows the approach introduced in EPA , 2007b . That report represented a change from an earlier PMN SNUR economic analysis ( EPA, 2 003 ), which used an average of GS - 12 Step 1 and GS - 12 Step 10 salaries.26

### 3.2 **SNUN Processing Costs** The list of review steps, estimates of extramural costs, and the percent of chemicals requiring a particular review step are derived from the costs for processing PMN submissions in Table VII - 1 of a 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 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 selected review step , and is inflated from 1993 prices using the Bureau of Labor Statistics (BLS) Employment Cost Index (ECI) data (BLS, 201 3 b ). The not seasonal ly adjusted E CI for total compensation of private industry professional and related workers (Series ID CIU2010000120000I) is used because 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. Table 15 contains the derivation of inflation factors for Agency extramural costs.27

The Consumer Price Index (CPI) was not rebased . 2 Inflation factors are rounded to three decimal places in this table, but calculations in this report use the unrounded values . 3 Beginning with th e report Economic Analysis of Expedited Significant New Use Rules for 25 Chemical Substances: EPA Docket OPPT - 2009 - 0922 (EPA 2010 ), 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 BL S retired the “white - collar” series. **Source:** (BLS 201 3b ) Bureau of Labor Statistics. Employment Cost Index

– Total Co mpensation: Professional and Related Private Industry, Not Seasonally Adjusted. (Series ID: CIU2010000120000I (B)), extracted April 2013 . (BLS, 201 3b ). The Percent of Cases column in Table 16 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 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 is 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. The Weighted Cost column is calculated by multiplying the un-weighted Costs (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 by electronic submission . This calculation yields total Agency costs of $ 5, 0 86 , per SNUN, for submission review and processing, as shown in Table 16 .**Agency Costs for SNUN and Other Submission Review and Processing EPA staff (FTE) Cost**  **Extramural Cost**  **2 Unw**  **eighted**

### 3.3 **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 2.2.8 . The Agency burden and cost due to TSCA §12(b) export notification result from three tasks . In the first task, EPA receives export notificati ons 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 US embassies (EPA, 2009b ) . (See Table 9 : Derivation of Total Mailing Cost for 12 Notices 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. B ecause 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 burden for the first two Agency activities is provided in Table 17 . 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 Table 15 . **Table 17**  **: TSCA 12(b) Export Notification Cost: Agency Burden per Activity (2012$)**  **Agency Activity Hours per**

Other burdens are from ICR No.: 0795.13 [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), updated for inflation.31 

## 4 **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. Itallows the Agency to take immediate action to mitigate an activity that the Agency deems harmful to the environment or human health. Diisocyanates are well known dermal and inhalation sensitizers in the workplace and have been documented to cause asthma, lung damage, and in severe cases, fatal reactions (U.S. EPA , 2011). The International Agency for Research on Cancer (IARC) classified toluene diisocyanate as “poss ibly carcinogenic to humans” (Carcinogenicity Group 2B) (IARC 1986; IARC 1999). TDI has also been classified by the European Commission (EC) as Category 3 for carcinogenicity (“causes concerns for humans owing to possible carcinogenic effects”) (European C ommission 1997, 2004; ESIS v.4.50 2006); and by the United States National Toxicology Program (NTP) as “reasonably anticipated to be a human carcinogen” (NTP 2005). There has been an increase in consumer availability of , or exposure to , polyurethane products intended to further react and undergo “curing” in the marketplace ( EPA, 2011 ). Use of TDI beyond the confines of a controlled production facility could result in exposures to consumer s through application or use of the product and the general public ( EPA, 2011 ). Unlike workers who are protected by workplace regulations and, in most cases, have access to hazard information and receive training for working with TDI, most consumers are unaware of the potential hazards of products containing TDI or other diisocyanates. Consequently, insufficient and inadequate hazard communication may lead to incorrect use and increased consumer and bystander exposures, particularly for sensitive groups, such as children. The proposed SNUR allows EPA to address the potential health effects that may result from exposures to the consumer while applying and/or using consumer products containing uncured TDI and related compounds (e.g., spray- applied sealants and coatings), by allowing the Agency to evaluate the use of, or exposure to, these chemicals, and to take preventive action to limit or prohibit any Significant New Use . The proposed rule also addresses the potential for incidental exposures to the general population while such products containing uncured TDI and related compounds are applied and/or used in or around buildings, including homes or schools. EPA also expects that the proposed rule may restrict future uses or exposure to the chemicals, as a company may choose to modify planned uses, and general population or consumer exposures to the chemical in such a way that does not trigger a SNUR, as opposed to submitting a SNUN. Therefore, the proposed SNUR may limit future exposure to the chemicals .32 

## 5 **Ad ditional A**  **nal ys**  **es 5.1**  **Regulatory**

**Flexibility A ct**  The Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et. seq.), as amended by the Small Business Regulatory Enforcement Fairness Act, requires regulators to consider the impact of regulations on small entities, in particular small businesses. 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 year 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 would 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, 5 00 including SNUN recordkeeping and reporting costs. The Agency currently offers some relief to certain 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 $ 6,1 00 for smaller firms. During the six -year period from 2005 - 2010, only three submitters self - identified as small in their SNUN submiss ion (EPA, 2012) . 14 EPA believes that there will be minimal impact to processors and importers of the chemical substance subject to the final SNUR as part of an article. The SNUR does not require processors and importers of articles that contain the chemic als subject to the final SNUR to conduct specific activities to ascertain if they are importing or processing an article that uses a chemical subject to the rule. Therefore processors and importers are expected to take actions that are commensurate with the level of risk each company perceives, and the resources it has available. EPA has no reason to believe that a firm would voluntarily incur substantial costs to comply with the SNUR, but rather EPA believes each firm will choose the most efficient route to identify whether it is importing or processing the subject chemical substances in articles. This leaves open the question of how many small businesses are affected but do not submit SNUNs. For example, businesses may change their behavior in order to us e a chemical in a manner that avoids triggering Significant New Use notification requirements, and make no submission to EPA. Data and resources were not available to estimate the number of such small businesses affected by the current rule . Based on past considerations and on the limited data available, EPA expects that any compliance with a SNUR will not have a significant economic impact on a substantial number of small entities. Small businesses may be affected by this proposed SNUR without EPA being aware; for example, if the firms have made no submissions or comments to EPA. However, even if a small business were interested in supplying a SNUR chemical, the SNUR’s impact on profits is generally expected to be minor. For example, the firm may have a s mall expense of keeping records (approximately $ 9.26 ) and/or of changing workplace practices to comply with any new restrictions. If modifying practices would be overly costly, the small business may instead forego production, thus sacrificing profits. The lost profits, if any, were not quantified for this report. 14 The three “small” submitters were identified by review of actual SNUN submissions from the years 2005 - 2010.33



### 5.2 **Unfunded Mandates Reform A ct (UMRA** **)** The proposed 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 chemicals. 

### 5.3 **Paperwork Reduction A ct (PRA** **)** According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et s eq., an Agency may not conduct or sponsor, and a person is not required to respond to a collection of information that requires OMB approval under the PRA, unless it has been approved by OMB and displays a currently valid OMB control number. The OMB contro l numbers for EPA ’ s regulations in title 40 of the CFR, after appearing in the **Federal Register** , are listed in 40 CFR, part 9, and included on the related collection instrument, or form, if applicable. The information collection requirements related to thi s action have already been approved by OMB pursuant to the PRA under OMB control number 2070 - 0038 (EPA ICR No. 1188). This action does not impose any burden requiring additional OMB approval. If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average 9 7 .66 hours per response : 0.82 hours for rule familiarization (Section 2.2.1 ), 2.80 hours for CDX registration, CDX el ectronic signature, and pay.gov account setup (Section 2.2.2 ), 91.68 hours for form completion, submission and recordkeeping (Sections 2.2.3 ), 1 hour for consumer notifications (Section 2.2.6 ) and 1.36 hours for export notification (Section 2.2.8 ). 

### 5.4 **Executive Order 13132, Fe deralism**  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, August 10, 1999). The proposed 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. 

### 5.5 **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, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low - income populations in the United States.34

The information collected under this proposed rule, if finalized, will assist EPA and others in determining the potential hazards and risks associated with various chemicals manufactured and used at high pro duction 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 lowincome and minority communities. 

### 5.6 **Executive Order 13045, Pr otection 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. 

### 5.7 **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 . 

### 5.8 **Executive Order 13211, Energy Supply, Distribution, or Use**  This rule is not subject to Executive Order 13211, entitled Actions C oncerning 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. 

### 5.9 **Executive Order 13563, Improving Regulation and Regulatory R**  **eview** 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 least 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 proposed 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 proposed 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 approache s given the available data and other constraints.35

## Ap **pendix A :**  **I nflators 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 for this report are for year- end 201 2 . 

### 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 loaded labor rates are given in Table A - 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 System (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 Com parability between SOC and OCS (BLS, 2006a and Weinstein, 2004). 

### A.1.1 Derivation of Labor Rates for Managerial, Professional/Technical, Clerical, and **Production Labor** Wages and fringe benefits for managerial, professional/technical, clerical and production labor were taken from the Bureau of Labor Statistics (BLS) Employer Costs for Employee Compensation (ECEC) data, 15 for December, for manufacturing industries. 16 The cost of fringe benefits such as paid leave and insurance, specific to each labor category, are taken from the same ECEC serie s . Fringe benefits as a percent of wages are calculated separately for each labor category . For example, for December 201 2 , the average wage rate for professional/technical 17 labor was $ 38.53 ; the average fringe benefit was $ 19.30 . Fringe benefits as a percent of wages were $ 1 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 major

15 This follows the approach introduced in Economic Analysis of Expedited Significant New Use Rules for 65 Chemical Substances: EPA Docket OPPT -2003 - 0063 (EPAB, 2007a) . 16 Employer Costs for Employee Compensation Supplementary Tables December 20 12 . (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. 17 This follows terminology introduced in EPAB, 2007a. 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).40

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 201 2 fully loaded wage for professional/technical labor is $ 38.53 × (1+0.5 009 + 0.17) = $ 64.38 . Fully loaded costs for managerial, clerical, and production labor are calculated in a similar manner, as shown in Table A - 1 . 

### A.1.3 **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. 18 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 o f Pollution Prevention 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 only benefits but also overhead.” (ICR No.1139.06)

18 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 S tep 10 salaries.41

### A.2 **Derivation of Inflation Factors** Complete information on the derivation of the inflation factors used is given in Table A - 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 Table A - 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). 19 “Starting year” indices in Table A - 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.

19 BLS has been publishing the NIACS - 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 .43

SA = Seasonally Adjusted. Total Comp = Total Compensation (wages/salaries and benefits) . 4th Q = Fourth Quarter. **Notes:** 1 In 2006, Bureau of Labor Statistics (BLS) Employment Cost Index (ECI) series “were rebased to December 2005 = 100 from June 1989 = 100.” The change is reflected in the indices in this table and explained on the BLS website, Employment Cost Index News Release Text: Employment Cost Index, March 2006 (BLS, 2006b ) . 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 industry Professional and Related Workers. After 2006, ECI indices are NAICS - SOC based: Seasonally Adjusted (SA) CIS2010000000000I for private industry All Workers, and not SA CIU2010000120000I (B ) for private industry P rofessional, and Related workers . 2 Inflation factors are rounded to three decimal places in this table, but calculations in this report use the unrounded values . BLS CPI values were published with one decimal place through 2006 and with three decimal places after that. 3 Beginning with the report Economic Analysis of Expedited Significant New Use Rules for 25 Chemical Substances: EPA Docket OPPT - 2009- 0922 ( EP A, 2010 ) we began to use the not - seasonally adjusted CIU2010000120000I for private industry Professional, and Relate d workers, instead of S A CIS2010000W00000I for private industry white collar workers because BLS retired the “white - collar” series .
