ABSTRACT

This report estimates the costs of the U.S. Environmental Protection Agency (EPA)’s final Significant 

New Use Rule (SNUR) for Di-n-pentyl phthalate (DnPP) (1,2-Benzenedicarboxylic acid, 1,2-dipentyl 

ester) (Chemical Abstracts Service Registry Number (CASRN) 131-18-0).

The final SNUR applies to all manufacturing, import, and processing of DnPP, excluding when the 

substance is used or sold for use as a chemical standard in phthalate testing - the sole ongoing use of the 

chemical.

1 Aside from the exempt use, EPA found no evidence of any manufacturing or importation into 

the United States. No data for DnPP were reported in the 2006 Toxic Substances Control Act (TSCA)

Inventory Update Reporting (IUR) database (EPA 2006a).

2

In addition, the Agency received no 

comments after the publication of the Phthalates Action Plan to indicate current production of the 

chemical for any uses besides use as a chemical standard in phthalate testing.

3 Because the domestic 

manufacture, import and processing of DnPP for the uses subject to the SNUR have been phased out,

there is expected to be no economic impact from the final SNUR.

The final SNUR will require persons to notify EPA at least 90 days before commencing the manufacture,

import, or processing of DnPP for any significant new use as defined in the SNUR. A firm intending to 

engage in these activities will be required to submit a Significant New Use Notice (SNUN). EPA is 

proposing the SNUR because of concerns regarding the adverse health effects presented by DnPP in 

humans and wildlife, as well as its environmental fate and exposure pathways. Although DnPP is no 

longer used in the United States, EPA is concerned that the manufacturing or processing of DnPP could 

be reinitiated in the future. The required notification provided by a SNUN will provide EPA with the 

opportunity to evaluate activities associated with a significant new use and an opportunity to protect 

against unreasonable risks, if any, from exposure to DnPP.

When submitting a SNUN, a firm incurs a modest submission cost of $8,571 and potentially other minor 

costs. However, since no firms have been identified which import, manufacture, or process DnPP for any 

significant new uses, EPA believes it is highly unlikely that any firm will incur this cost. EPA does not 

require the development of test data for submission of a SNUN, although a firm may submit test data 

already in its possession or 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 final SNUR.

In addition to the firms that make a SNUN submission, the final SNUR may also impact 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. However, this may not be a concern given that the domestic 

manufacture, import and processing of DnPP for the uses subject to the SNUR have been phased out.

Costs are estimated at the firm level and reflect the burden of a SNUR on the firms that will make a 

submission. 

 

1 Both Cambridge Isotope Laboratories, Inc. and Accustandard.com sell DnPP as a standard for phthalate testing 

(CIL 2010a, Accustandard 2010). Columbia Analytical Services, Inc. does not sell DnPP but uses DnPP for on-site 

phthalate testing (CAS 2010a).

2 The IUR compiles production data from manufacturers and importers of certain chemical substances (including 

DnPP) listed on the TSCA Chemical Substance Inventory. Sites are only required to submit IUR data if they 

manufacture or import more than 25,000 lbs of a chemical during the reporting year. 2006 was the most recent year 

with data availability.

1. INTRODUCTION

This report presents the U.S. Environmental Protection Agency (EPA), Office of Chemical Safety and 

Pollution Prevention’s (OCSSP’s) analysis of the potential costs incurred as a result of a final Significant 

New Use Rule (SNUR) for Di-n-pentyl phthalate (DnPP) (1,2-Benzenedicarboxylic acid, 1,2-dipentyl 

ester) CASRN 131-18-0. SNURs are proposed by EPA under the authority granted by Section 5(a)(2) of 

TSCA. The final SNUR will require persons to notify EPA at least 90 days before commencing the 

manufacture, import, or processing of DnPP, excluding when the substance is used or sold for use as a 

chemical standard in phthalate testing – the sole ongoing use of the chemical. Additionally, persons who 

manufacture or process DnPP solely for export will be exempt from the notification requirements of the 

final SNUR, if when distributing the substance in commerce, it is labeled in accordance with TSCA 

section 12(a)(1)(B). EPA promulgates a SNUR for a substance when potential uses could result in 

increased exposure to, or releases of, the substance which in turn, could present an unreasonable risk to 

health or the environment.

1.1 Background

As part of EPA’s efforts to enhance the existing chemicals program under TSCA, the Agency identified 

an initial list of widely recognized chemicals for the development of an Action Plan. Phthalates were 

selected because of their toxicity and the evidence of pervasive human and environmental exposure. The

Action Plan summarized readily available use, exposure, and hazard information for eight phthalate esters

(including DnPP);4considered which authorities provided under TSCA and other statutes could be used to 

address potential concerns; and described various courses of actions available to EPA to address the 

concerns (EPA 2009d).

5

It is important to note that, unless specified, the following sections describe all 

phthalates, not just DnPP. 

Uses and Substitutes

The major use of phthalates is as plasticizers, additives incorporated into plastics and elastomers used to 

impart flexibility and other desirable properties into the material (Australian Government 2008a-h; HSDB

2009; Krauskopf and Godwin 2005). Phthalate esters make up 92 percent of the plasticizers produced 

worldwide, while di (2-ethylhexyl) phthalate (DEHP) makes up 51 percent of those phthalates (Rahman 

2004a). It is not clear what portion, if any, DnPP historically contributed to these totals. A major 

application of plasticizers is in polyvinyl chloride (PVC), which is used in a variety of industrial and 

commercial products, as well as specialized medical and dental applications. The particular phthalate or 

combination of phthalates used in a particular product’s formulation depends on the properties the 

phthalates impart, as well as their cost.

Phthalates can often substitute for each other in specific applications. Furthermore, although phthalates 

are still the main PVC plasticizers, numerous other substances can serve as substitutes. These include 

other phthalates, trimellitates, and monomeric plasticizers, such as epoxidized soybean oil. Many of these 

substitutes have specialized uses and are frequently more expensive than phthalates, but some exhibit 

properties that make them particularly suited to certain applications. 

 

4 The list of eight phthalates was assembled by combining phthalates identified by the Consumer Product Safety 

Improvement Act of 2008 (CPSIA) and those being evaluated by the EPA for the Integrated Risk Information 

System (IRIS), based on advice from the National Academy of Sciences (NAS 2008).

Health Effects

A comparison of toxicity information from laboratory animal studies for phthalates as a chemical group 

allows generalizations to be drawn with respect to certain health endpoints. For example, acute toxicity, 

skin and eye irritation, and sensitization potential are low for all phthalates tested, and the majority of the 

phthalates were not genotoxic. The most sensitive health outcomes from phthalate exposure shown in 

laboratory animals are phthalate syndrome effects, which consist of changes in the fetal development of 

the reproductive system (NAS 2008; NTP-CERHR 2003a-e, 2006; EC 2003a-b, 2008a-b; Australian 

Government 2008a-h). The phthalates that are the most potent at causing phthalate syndrome effects are 

generally those with linear ester side chains having 4-6 carbons (NAS, 2008). DnPP has a linear carbon 

chain length of 5 carbons. 

There are no known human studies of exposure to DnPP. However, several human studies have reported 

associations of exposure of some phthalates with adverse reproductive outcomes and developmental 

effects similar to those in the rat, although no causal link has been established (Swan et al 2005; Huang et 

al 2009). The reproductive developmental effects observed in humans include shortened anogenital 

distance observed in newborn boys; and shorted pregnancy, lower sex and thyroid hormones, and reduced 

sperm quality observed in adults. Recent scientific attention has focused on evaluating the cumulative 

effects of mixtures of phthalates on testosterone production, fetal mortality, and male and female 

reproductive development later in life, and shown all mixtures were cumulative for all endpoints (Rider et 

al. 2008, 2009; Howdeshell et al. 2007, 2008a, 2008b; Gray et al. 2006; Hotchkiss et al. 2004).6

Based on data discussed in this section and DnPP’s general structure and categorization as a phthalate, 

EPA is concerned that human health effect of DnPP exposure may be similar to that observed for some 

other phthalates.

Environmental Exposure and Effects

Phthalates are released into the environment from multiple sources, including: industrial releases; the 

disposal of manufacturing, processing and industrial wastes; municipal solid waste; land application of 

sewage sludge; and release from products containing phthalates. Due to their pervasive use and release, as 

well their propensity for global transport, various phthalates may be found in most environmental media, 

including ambient air, surface water, soil, sediment (Babich et al. 2004; Clausen et al. 2004; EC 2003 a-b, 

2003-04, 2008a-b; CPSC 2001, 2002). Exposures due to environmental releases from the phthalate 

plasticized PVC material in the environment indicate a potential for bioavailability and bioaccumulation 

in aquatic and terrestrial food webs.7 

EPA is concerned that the environmental effects of DnPP may be similar to those of other phthalates 

studied. Other phthalates studied have been shown to have biological effects in all studied animal groups 

and have been observed at environmentally relevant exposures in the nanogram/liter to microgram/liter 

range. The combination of the inherent toxicity, variable solubility, log of the octanol-water coefficient 

values, and bioconcentration factor (BCF) values among the studied phthalates elicit both acute and 

chronic toxicity to aquatic and terrestrial wildlife by targeting thyroid function, liver function, 

 

6 A major cumulative hazard assessment of phthalates is scheduled to be conducted by the Consumer Product Safety 

Commission’s (CPSC’s) Chronic Hazard Advisory Panel (CHAP) as directed by CPSIA, with an anticipated 

completion date of 2012.

7 Data from the National Health and Nutrition Examination survey (NHANES) indicates widespread exposure of the 

general population to phthalates. Biomonitoring data have demonstrated that humans are exposed to phthalates in 

utero, as infants, during puberty, and in adult life, and that people are exposed to several phthalates at once (CDC 

2009).

reproduction, and other physiological mechanisms (EC 2003 a-b, 2003-04, 2008a-b; Oehlmann et al., 

2008; Staples et al., 1997).

Current Manufacturing

EPA analyzed the most recent data from the TSCA IUR database (2006 reporting) and found no evidence 

of production of DnPP. Additionally, following publication of the Action Plan, there were no comments 

provided during the comment period that will provide any indication of ongoing production of DnPP.

8

 

However, subsequent internet queries identified several companies which either use or sell DnPP as a 

chemical standard for use in phthalate testing.9 As a result, EPA is proposing a SNUR for DnPP, 

excluding use of the substance as a chemical standard in phthalate testing.

1.2 Statutory Authority 

Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to determine that a use of a chemical 

substance is a “significant new use.” EPA must make this determination by rule after considering all 

relevant factors, including those listed in TSCA section 5(a)(2). Once EPA determines that a use of a 

chemical substance is a significant new use, TSCA section 5(a)(1)(B) requires persons to submit a 

Significant New Use Notice (SNUN) to EPA at least 90 days before 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.

1.3 Summary of Methodology

This analysis quantifies, to the extent possible, the costs of the final rule to society by identifying the 

costs to industry associated with performing the required reporting and recordkeeping activities, and the 

costs to EPA of administering the rule. Industry costs consist of rule familiarization; registration with the 

Central Data Exchange (CDX) electronic reporting tool; collection, compilation, and submission of 

required information for significant new uses of the subject chemicals; export notification; and 

recordkeeping. Agency costs include reviewing and processing the data received as a result of the rule. 

Data sources for this analysis include burden estimates derived from previous information collection 

requests and economic analyses for related rules, compensation data acquired from government 

publications, and supplementary market research.

In addition to estimated costs, this report qualitatively discusses the benefits of the final rule based on the 

value of the information it will provide.

1.4 Organization of this Report

The remainder of this report provides EPA’s economic analysis in support of the final rule. Chapter 2

presents estimates of the costs incurred by manufacturers, importers, and/or processors under the SNUR 

options. Chapter 3 shows estimates of the government costs associated with the administration of the final 

 

8 The last year of reported DnPP production in the IUR database was 1990, in which between 100 million and 500 

million pounds of DnPP were produced. 

9 Both Cambridge Isotope Laboratories, Inc. and Accustandard.com sell DnPP as a standard for phthalate testing 

(CIL 2010a; Accustandard 2010). Columbia Analytical Services, Inc. does not sell DnPP but uses DnPP for on-site 

phthalate testing (CAS 2010a). It is not known what proportion of the market these three companies represent, nor 

how large the market is; however, given the IUR data and the lack of public comments received following the 

Action Plan, it is likely that this ongoing market is small.

rule. Chapter 4 presents an analysis of other impacts, as required by various statutes and executive orders.

Chapter 5 discusses the benefits of the final rule.

Note that all dollar amounts in this analysis are reported in December 2011 dollars, which is the latest

year for which complete data are available, except for U.S. Postal Service Mailing Rates, which were 

acquired in January 2012.

2. INDUSTRY COMPLIANCE COSTS

The final SNUR discussed in this report specifies that significant new uses of DnPP that require reporting 

under section 5(a)(2)(A) of TSCA include the manufacture, import, or processing of DnPP, except when 

used or sold for use as a chemical standard in phthalate testing. Therefore, a firm intending to 

manufacture, import, and/or process DnPP for any use other than as a chemical standard in phthalate 

testing must submit a SNUN. Alternatively, a firm can decide not to manufacture, import, and/or process 

the chemical for 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 for a significant new use, which, in this case, means any 

manufacture, importing, and/or processing of this chemical or articles containing the chemicals, 

except use as a chemical standard in phthalate testing.

10.11 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 

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, or 

processing of DnPP for the intended 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 products, 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 2.2.7 for details). Because the domestic 

manufacture, import and processing of DnPP for the uses subject to the SNUR have been phased out,

EPA expects that no firms will choose this option.

 Option 2: Decide not to manufacture, import, and/or process the chemical. The firm may decide 

simply not to proceed to manufacture, import, and/or process the chemical. While this option avoids 

the costs of submitting a SNUN, it entails the ‘hidden’ cost of the profit that will be foregone as a 

result of not engaging in the commercial activity originally planned. Similarly, if the firm will have 

used a given amount of DnPP in the production of another product, and must substitute to a more 

costly substance, it will incur those additional “hidden” costs of production. However, these hidden 

costs are expected to be minimal, if not zero, because DnPP is not currently manufactured in the 

United States except as a chemical standard for use in phthalate testing. If the firm elects to produce 

DnPP 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. 

Because the domestic manufacture, import and processing of DnPP for the uses subject to the SNUR have 

been phased out, EPA does not expect there to be compliance cost associated with either of the options.

The remainder of this chapter estimates the quantified portion of costs associated with the final SNUR. 

Section 2.1 summarizes 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 

 

10 EPA notes that, in accordance with TSCA section 12(a) and 40 CFR 721.45(g), persons who manufacture or 

process DnPP solely for export will be exempt from the notification requirements of 40 CFR 721.25, if when 

distributing the substance in commerce, it is labeled in accordance with TSCA section 12(a)(1)(B). Further, EPA 

notes that the exemption from the TSCA section 12(b) notification requirements for exported articles (see 40 CFR 

707.60(b)) will remain in force. Thus, persons who export DnPP as part of an article will not be required to provide 

export notification.

11 Section 5(h)(3) of TSCA, 15 USC 2604(h) exempts substances that are manufactured in small quantities solely for 

research and development (R&D) from the section 5(a) notice requirements. No application is required for the 

exemption for R&D under section 5(h)(3) (U.S. EPA 1986).

export notification. Total costs under each option are presented in Section 2.3. 

2.1 Wage Rates

The final rule involves activities that may require efforts by employees in three labor classifications: 

managerial, technical, and clerical. Costs for each activity are calculated by estimating the labor hours 

required in each labor category and multiplying those burden hours by the wage rate for the 

corresponding labor category. This section presents the estimated wage rate in each labor category.

Loaded wage rates for managerial, technical, and clerical personnel are derived by combining data on 

wages and fringe benefits with estimates of overhead rates, following the methodology described in Wage 

Rates for Economic Analysis of the Toxics Release Inventory Program (EPA, 2002b). Wage data for each 

labor category for December 2011 are provided by the Employer Costs for Employee Compensation 

(ECEC) Supplemental Tables available on the BLS website (BLS, 2012a). The loaded wage rate is $70.72 

for managerial labor; $64.66 for technical labor; and $29.63 for clerical labor. Table 1 presents the data 

used to calculate the loaded wage rates for the three labor categories.

2.2.1 Rule Familiarization

The final rule requires submitters and their staff to become familiar with the SNUR and its various 

requirements. Rule familiarization is estimated to require 0.55 hours of technical labor and 0.27 hours of 

managerial labor, as described in the Economic Analysis of the Premanufacture Notification Electronic 

Reporting Final Rule (EPA, 2009a), which measures the costs of mandatory electronic reporting of 

SNUNs and other TSCA Section 5 notices. As shown in Table 2, the total labor cost associated with rule 

familiarization is estimated at $54.43.

2.2.2 CDX Registration, CDX Electronic Signature, and Pay.gov Account Setup

The final SNUR requires submission of a SNUN for any firm that chooses to manufacture, import, and/or 

process a chemical for a significant new use. First-time submitters of any TSCA section 5 notice 

(including Premanufacture Notices (PMNs), SNUNs, Test Market Exemption (TME) applications, Low 

Volume Exemption (LVE) notices, Low Exposure/Low Release (LoREX) exemption notices, 

Biotechnology Notices for genetically modified microorganisms, Notices of Commencement of 

Manufacture or Import (NOCs), and support documents to Section 5 notices) are required to register their 

company and key users with the CDX reporting tool, deliver a CDX electronic signature to EPA, and 

establish and use a Pay.gov E-payment account.12 These activities are only required of first-time 

submitters of any Section 5 notice. These activities are estimated to require the following burden hours, 

based on the estimates presented in the Economic Analysis of the Premanufacture Notification Electronic 

Reporting Final Rule (EPA, 2009a):

 CDX registration: EPA estimates that companies will spend approximately 0.18 hours per 

employee to register with CDX, and that an average of four technical staff members and one 

manager will need to register for each company, totaling approximately 0.92 hours of burden per 

company.

 CDX electronic signature: EPA estimates that companies will spend 0.25 hours preparing, 

submitting, and filing an electronic signature agreement (Authentication of Identity) form to EPA 

per employee. This burden will apply to four technical staff members and one manager per 

company, totaling 1.25 hours of burden per company. In addition, EPA estimates that a manager 

will spend an additional 0.50 hours accessing, preparing, and submitting verification forms 

(Verification of Authorization) for all authorized submitters to EPA. The total burden incurred by 

companies submitting and then verifying electronic signature agreements is 1.75 hours. Note that 

this burden does not include any additional time required to contact EPA’s CDX help desk to 

notify a change of submitter status, should one occur. Filing the electronic signature agreement 

requires an additional mailing cost of $2.55 per company (including five $0.45 stamps13 and five 

$0.06 business envelopes14).

 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.

 

12 Although the final 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.

2.2.3 Form Completion and Submission Fee

Respondents who choose to submit a SNUN are required to gather and submit information regarding the 

data elements identified in the applicable SNUN reporting form. The methodology and calculations used 

in this analysis assume that the employee responsible for collecting, filling out, and submitting the 

requested information has a reasonable level of familiarity with the company and knowledge of 

operations at the site. It is assumed that for most entities these tasks are similar to other employee duties 

that require familiarity with EPA, State, and other Federal agency requests for chemical information and 

do not require additional familiarization or training beyond the basic rule familiarization described above. 

In addition, this analysis focuses on the marginal costs of submitting information for the final rule and not 

the total costs for the company to comply with a range of other Federal and State environmental, health, 

and safety regulations or accounting requirements that rely on this type of information.

Estimates of the costs of completing a Significant New Use Notice (SNUN) form are based on the costs 

of completing a PMN submission, since the data requirements are the same and the same form is used for 

both. The PMN submission costs came from EPA's 1994 Regulatory Impact Analysis of Amendments to 

Regulations for TSCA Section 5 Premanufacture Notifications, which relied on industry estimates of the 

effort needed to collect and compile all data required for a PMN submission, prepare the form, submit the 

form and data to EPA, and maintain a file of the submission (EPA, 1994, Table III-2 and pages III-11, -

12, and -13). The 1994 estimates were based on a survey conducted by the Chemical Manufacturers 

Association, which became the American Chemistry Council. These burdens include “the time spent 

reading and becoming familiar with the form, gathering the required information and preparing the report, 

producing sanitized responses for items claimed as confidential business information, and maintaining a 

file of the submission” (EPA, 1994. p. III 11-13). The burden associated with SNUN submission and 

preparation has been adjusted to reflect burden reductions resulting from the 2009 final PMN Electronic 

Reporting (ePMN) Rule that requires the electronic 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, 2009a).15 In addition, electronic submission is expected

to generate and an additional 0.18 hours of technical burden, for the completion of the User Fee Payment 

Identification Number and email address data elements on the electronic SNUN form.

SNUN form completion and electronic submission is estimated to require approximately 74 hours of 

technical labor and 18 hours of managerial labor (EPA, 2009a). Table 4 combines the estimated reporting 

burden and loaded wage rates for all three labor categories to estimate the per-SNUN cost of form 

completion. The labor cost incurred by a SNUN submission for both large and small business submitters 

is estimated at $6,071.

Reporting Final Rule (EPA, 2009a, page 7)

3 Technical and managerial labor burden is from the PMN Amendments RIA (EPA, 1994, Table III-2). An additional eleven 

minutes (0.18 hours) of technical burden is estimated to complete the User Fee Payment Identification Number and Email 

Address data elements on the Electronic SNUN form (EPA, 2009a page 15).

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 5 adds the labor cost and 

submission fee to estimate the total cost of a SNUN submission. The total cost of a SNUN submission is 

$8,571 for large business submitters and $6,171 for small business submitters.

2.2.4 Recordkeeping

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 will be five percent of 

 

estimates from the 1994 RIA (EPA, 1994, p. III-14). These burden estimates (the 0.5 for clerical burden and 0.5 for 

technical burden) are based on the recordkeeping burden for polymer exceptions and not the recordkeeping burden 

associated with PMN submissions.

Therefore, for this analysis, the 0.5 hour for clerical labor and the 0.5 hour for technical labor were removed. It is 

important to note that for this analysis, clerical burden 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.

SNUN submission hours, or about five to six hours. For this report, the SNUN recordkeeping hours were 

included in the SNUN submission hours (see Section 2.2.3) and the SNUN recordkeeping costs under 40 

CFR §721.40 were not separately estimated.

16

Recordkeeping for Companies that Do Not Submit a SNUN

If a firm that manufactures, imports, or processes a substance subject to the final SNUR chooses not to 

submit a SNUN, they must keep records that document compliance with SNUR conditions for avoiding a 

Significant New Use. Such recordkeeping requirements essentially involve copying and filing relevant 

records, including those related to category of use. Records must be maintained for five years from the 

date of their creation (40 CFR 721.40). For firms that choose to not submit a SNUN, costs for compliance 

with the recordkeeping requirements are estimated to be five percent of the reporting burden for reporting 

information for a specific section of the SNUN form and are performed by clerical staff (EPA, 2005b, 

pages 10 and 14). EPA used the per-activity burden for reporting, human exposure, category of use and 

releases to the environment presented in the Information Collection Request (ICR) for TSCA Section 

5(a)(2) Significant New Use Rules for Existing Chemicals (Renewal) (EPA, 2005b, page 12). Any clerical 

burden associated with these activities was removed to reflect the burden reduction associated with 

electronic submissions (EPA, 2009a). 

The recordkeeping burden for a company that does not submit a SNUN is estimated at 0.15 hours and 

$9.70 and is derived in Table 6.

2.2.5 Customer Notification

Manufacturers, processors, and importers of chemicals subject to SNURs must notify recipients of such 

chemicals of the SNUR or verify that knowledge of the SNUR has been otherwise acquired by recipients, 

or that the recipients are unable to engage in significant new uses. Since it is not expected that all such 

entities will have complete knowledge of all uses of any products subject to a SNUR, and because filing a 

 

16 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.
Economic Analysis of SNUR for U.S. EPA Office of Chemical Safety and Pollution Prevention

Di-n-pentyl Phthalate (DnPP) 11 Economic and Policy Analysis Branch

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 $64.66 per manufacturer, processor, or importer 

per chemical. The final SNUR applies to all manufacturing, import, and processing of DnPP, excluding

when the substance is used or sold for use as a chemical standard in phthalate testing - the sole ongoing 

use of the chemical.17 Aside from the exempt use, EPA found no evidence of any manufacturing or 

importation into the United States. Therefore, customer notifications will not be necessary. 

2.2.6 Import Certification

In general, promulgation of a SNUR triggers a TSCA Section 13 import certification requirement and the 

corresponding regulations at 19 CFR §12.118 to 12.127 and 19 CFR §127.28 for all imports of the 

relevant chemical substances. Thus, any U.S. manufacturer, importer, or processor receiving an imported 

shipment of chemicals subject to the final SNUR will have to certify that all chemical substances in the 

shipment either comply with all applicable rules and orders under TSCA or that all chemical substances in 

the shipment are not subject to TSCA.18 The statement must be on or attached to a commercial invoice or 

entry document belonging to the imported shipment.

Import certification is fulfilled by checking a box on an invoice or entry document and EPA assumes that 

it generally imposes no additional burden or cost on the importer. Any potential burden associated with 

submitter’s familiarization with this requirement is assumed to be included in the more general SNUR 

familiarization burden discussed above.

2.2.7 Export Notification

Under Section 12(b) of TSCA, exporters must notify EPA if they export or intend to export a chemical 

subject to various TSCA sections (40 CFR §707.60 through 75). For TSCA 5(a)(2) (the section under 

which EPA promulgates significant new use rules) and certain other TSCA sections, this is a one-time 

notification requirement19 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 variety of unrelated 

 

17 Both Cambridge Isotope Laboratories, Inc. and Accustandard.com sell DnPP as a standard for phthalate testing 

(CIL 2010a, Accustandard 2010). Columbia Analytical Services, Inc. does not sell DnPP but uses DnPP for on-site 

phthalate testing (CAS 2010a).

18 The exact statements are as follows: For imports of chemical substances subject to TSCA, “I certify that all 

chemical substances in this shipment comply with all applicable rules or orders under TSCA and that I am not 

offering a chemical substance for entry in violation of TSCA or any applicable rule or order under TSCA.” For 

imports of chemical substances not subject to TSCA (e.g., pesticides), “I certify that all chemicals in this shipment 

are not subject to TSCA.” (40 CFR 707.20)

19 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).

uses, manufacturers, and processors, making it impractical within the resources available for this report to 

assess the potential number of exporters and importing countries per chemical. 

Most underlying data in this section come from the (2009 TSCA Section 12(b) ICR), ICR No.: 0795.13

OMB Control Number 2070-0030 [Information Collection Request for] Notification of Chemical Exports 

- TSCA Section 12(b) Supporting Statement for Request for OMB Review under the Paperwork 

Reduction Act (EPA, 2009b). 

Estimated Number of Annual Export Notifications per Exporter

EPA’s 2009 TSCA Section 12(b) ICR estimated that the average exporter making notifications would 

make 12 notifications per year.

20 This includes notifications resulting from SNURs and notifications 

resulting from other TSCA activities. Therefore, it is likely that an exporter will make less than 12 

notifications per year as a result of this final SNUR. A notification is typically no more than one page per 

chemical/country combination, and one notification mailing often includes multiple chemicals and/or 

destination countries.21

The percent of notifications resulting from SNURs in general is unknown, and it is also unknown how 

many notifications may result from this rulemaking, as not all manufacturers may choose to export a 

chemical, or they may make several notifications for a single chemical. 

Exporter Costs22

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 (U.S. PS) as 

first-class registered mail with a return receipt (U.S. PS, 2012). The estimated per-shipment and annual 

mailing costs incurred by individual submitters are detailed in Table 7.

 

20 EPA calculated the average number of export notifications per exporter in the 2009 TSCA Section 12(b) ICR

(EPA, 2009b) by dividing the estimated number of submitted notifications (3,500) by the estimated number of 

exporters (300).

approximately three weeks in early 2010.

mailing method comes from the Economic Analysis of the Proposed Change to TSCA Section 12(b) Export Notification 

Requirements, November 2005 (EPA, 2005), as clarified in a later SNUR economic analysis (EPA, 2007a, Table 8). 

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 that there will be approximately 300 submitters per year in near-future years (EPA, 2009b). Of 

these 300 submitters, EPA estimated that 200 companies were near the lower burden estimate of two 

hours per year, and 100 companies were near the upper estimate of 24 hours per year. Compiling the list 

for all respondents was therefore estimated to take 2,800 hours (2 hours x 200 firms plus 24 hours x 100 

firms), or an average of about 9.3 hours of technical time per firm per year for 12 notifications per year 

(EPA, 2009b).

Write or Revise Export Notification. Companies that export chemicals subject to 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 8 below. EPA 

estimates that the burden associated with making one notification is approximately 1.4 hours and $84.06. 

Because there is no manufacture or importation aside from the exempted use, EPA does not expect any 

notifications costs.

The number of firms affected that do not make submissions to EPA is not known; therefore, costs are not

customer notification ($64.66) may apply.

Notes:

1 Firms may experience costs related 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. Additionally, export notification costs are 

somewhat independent of the option because the production of DnPP for export purposes only is not subject to the 

final SNUR notification requirements under 40 CFR 721.25.

2 Quantified costs are attributable to the SNUR only if a firm will not otherwise follow the specified practices. Costs 

are detailed in Section 2.2.

3 EPA does not require the development of test data for submission of a SNUN, although a firm may submit test data 

already in its possession and/or describe any other available data. Because EPA does not require the development of 

test data, EPA assumes that no firms will incur testing costs as a result of the final SNUR.

2.4 Likelihood of a SNUN Submission

This analysis assumes that no entities are expected to submit a SNUN. EPA has, over the years, 

promulgated SNURs that cover a total of more than 1,000 chemicals. In response, the Agency receives 

only a handful of SNUNs per year. For example, the number of SNUNs received was six in Federal fiscal 

year (FY) 2007, eight in FY2008, seven in FY2009, two in FY2010, and ten in FY2011.23 In addition, all 

of the chemical subject to this final rule are currently not being manufactured, imported or processed

except for the exempted use. 

2.5 Potential for Subsequent Regulatory Action

The Agency recognizes that if submission of a SNUN does result from a SNUR, the Agency may take 

additional regulatory actions under TSCA. These additional regulatory actions might be necessary to 

further evaluate an intended new use and associated activities, or to prohibit or limit that activity before it

occurs to prevent unreasonable risk of injury to human health or the environment. It is not known what 

specific subsequent regulatory actions, if any, the Agency may determine are necessary after reviewing a 

SNUN. Any such actions are highly dependent on the circumstances surrounding the individual SNUN 

(e.g., available information and scientific understanding about the chemical and its risks at the time the 

SNUN is being reviewed). 

Should the 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 will be an 

assessment of the costs and benefits of those actions.

3. AGENCY 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 2011 (OPM, 2011). EPA assumes 

that, on average, a federal GS-13, Step 5 full-time equivalent (FTE) will conduct its collection and 

administrative activities under the final rule.24 The average salary for a GS-13 Step 5 employee was 

$100,904 in 2011 without fringe benefits and overhead costs. In order to derive the fully loaded salary, 

EPA multiplied the annual salary by an assumed loading factor of 1.6 to reflect federal fringe benefits and 

overhead (EPA, 2009c), which results in a fully loaded annual salary of $161,446 (see Table 10). 

Dividing the fully loaded annual salary by 2,080 hours (i.e., the number of hours in a work year) yields an 

estimated hourly FTE wage rate of $77.62.

Fully loaded costs for Agency labor are shown in Table 10.

2,080 hours.

(EPA 1992, page 30, footnote 9).

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 

 

24 The GS-13 Step 5 is consistent with ICR No. 0574.14 (12/18/2007) (EPA, 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, 2003), which used an average of GS-12 Step 1 and GS-12 Step 10 

salaries.
Economic Analysis of SNUR for U.S. EPA Office of Chemical Safety and Pollution Prevention

Di-n-pentyl Phthalate (DnPP) 18 Economic and Policy Analysis Branch

requires the electronic submission of all TSCA section 5 notices. Electronic submission of SNUN forms 

is expected to reduce Agency burden by 16.5 percent (EPA, 2009b, p.28).

For each review step, the “EPA staff” cost is calculated by multiplying the number of FTEs (in the first 

column) by the fully loaded hourly salary. This shows EPA staff cost for chemicals requiring the selected 

review step. 

The Extramural Cost column shows costs for contractor support and other outside purchases for 

chemicals requiring the selected review step, and is inflated from 1993 prices using the Bureau of Labor 

Statistics (BLS) Employment Cost Index (ECI) data (BLS, 2012b). The ECI for total compensation (not 

seasonally adjusted) 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 11 contains the 

derivation of inflation factors for Agency extramural costs.

Seasonally Adjusted. (Series ID: CIU2010000120000I), extracted March 22, 2012 (BLS 2012b).

The ‘Percent of Cases column’ in Table 12 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 cause 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 typical PMN because of factors such as the need to retrieve old PMN records 

from archives, and the likelihood that more data requiring EPA review are submitted with a SNUN than 

will be submitted on average with a PMN. Resources were not available to update the review hours to 

reflect the current review process or to tailor the cost estimates to SNUNs. Therefore, for this analysis, the 

review steps and weighting factors are assumed to be the same as those derived in 1994 for PMNs.

Values in the ‘Weighted Cost’ column are calculated by multiplying the un-weighted 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 electronic 

submission. This calculation yields total Agency costs of $5,066 per SNUN, for submission review and 

processing, as shown in Table 12.

3.3 Export Notification Cost

Under TSCA Section 12(b), exporters must notify EPA if they intend to export chemicals subject to 

SNURs. The Agency burden and cost due to TSCA §12(b) export notification result from three tasks. In 

the first task, EPA receives export notifications from companies that intend to export one of the chemicals 

subject to TSCA §12(b) (EPA, 2009b). In the second task, EPA staff prepares separate notification letters 

that are subsequently reviewed and delivered to importing countries, their embassies, or representatives, 

and to the importing country’s U.S. embassies (EPA, 2009b). (See Table 7 for the cost of mailing one 

notification). The third task is comprised of EPA staff responses to public inquiries and other TSCA 12(b) 

activities. The work of responding to non-routine requests for information and clarification from industry 

and importing countries, and of handling other tasks associated with the TSCA §12(b) program, was 

estimated to require roughly 400 hours per year (EPA, 2009b). Since the current rulemaking covers only a 

very small percent of the chemicals subject to TSCA 12(b) reporting, a very small percent of such activity 

will be attributable to the current rulemaking. 

Because it is unknown how many, if any, notifications EPA will receive or send as a result of the current 

rulemaking, the costs to the Agency are presented per activity. The estimated burden for the first two 

Agency activities is provided in Table 13. To estimate the Agency cost, hourly burdens are multiplied by 

the loaded wage rate of a GS-13, Step 5, which is derived in Table 10.

4. ADDITIONAL ANALYSES

This section presents additional analysis of other potential impacts of this rulemaking, as required under 

various statutes and executive orders.

4.1 Regulatory Flexibility Act

Pursuant to section 605(b) of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.), the Agency 

hereby certifies that promulgation of this SNUR will not have a significant adverse economic impact on a 

substantial number of small entities. The rationale supporting this conclusion is as follows. The 

requirement to submit a SNUN applies to any person (including small or large entities) who intends to 

engage in any activity described in the rule as a significant new use. Where a use is new, by definition no 

small or large entities presently engage in such activities. Although some small entities may decide to 

manufacture or process a substance for the new use after the SNUR is promulgated, EPA receives very 

few SNUNs, and few of those are submitted by small entities. In response to the promulgation of SNURs 

covering over 1,000 chemical substances, the Agency receives only a handful of SNUNs per year. For 

example, the number of SNUNs was four in Federal fiscal 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 will alter the pattern of SNUN 

submissions that EPA has historically seen. In addition, the estimated reporting cost for submission of a 

SNUN is minimal regardless of the size of the firm, averaging about $8,600 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 $6,200 for smaller firms. During the six year period from 2005-2010, only three submitters selfidentified as small in their SNUN submission25 (EPA, 2012). EPA believes the cost of submitting a 

SNUN is relatively small compared the cost of developing and marketing a chemical new to a firm and 

that the requirement to submit a SNUN generally does not have a significant economic impact. 

EPA believes that the potential economic impact of complying with a SNUR is not expected to be 

significant or adversely affect a substantial number of small entities. 

4.2 Unfunded Mandates Reform Act

The final rule does not impose any enforceable duty, contain any unfunded mandate, or otherwise have 

any effect on small governments because none of the current producers of the subject chemicals are 

governments. Additionally, it is not expected that any governments will initiate production of these 

chemicals. 

4.3 Paperwork Reduction Act

According to the Paperwork Reduction Act (PRA), 44 U.S.C. 3501 et seq., an Agency may not conduct or 

sponsor, and a person is not required to respond to a collection of information that requires OMB 

approval under the PRA, unless it has been approved by OMB and displays a currently valid OMB 

Control number. The OMB control numbers for EPA's regulations 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 this action have already been 

approved by OMB pursuant to the PRA under OMB control numbers 2070-0038 (EPA ICR No. 1188) 

and 2070-0030 (EPA ICR No. 0795). 

 

25 The three “small” submitters were identified by review of actual SNUN submissions from the years 2005-2010.
Economic Analysis of SNUR for U.S. EPA Office of Chemical Safety and Pollution Prevention

Di-n-pentyl Phthalate (DnPP) 22 Economic and Policy Analysis Branch

If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average 98.2 hours 

per response: 0.82 hours for rule familiarization (Section 2.2.1), 2.80 hours for CDX registration, CDX 

electronic signature, and pay.gov account setup (Section 2.2.2), 92.2 hours for form completion, 

submission and recordkeeping under CFR §721.40 (Sections 2.2.3 and 2.2.4), 1 hour for consumer 

notifications (Section 2.2.5) and 1.36 hours for export notification (Section 2.2.6). The burdens for rule 

familiarization, CDX registration, CDX electronic signature, pay.gov account setup form completion, 

submission, and recordkeeping are approved under EPA ICR No. 1188 (OMB control number 2070-

0038). The burden for export notification is approved under EPA ICR No. 0795 (OMB control number 

2070-0030)

4.4 Executive Order 12898: Federal Actions to Address Environmental Justice in Minority 

Populations and Low-Income Populations

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.

The information collected under this final rule will assist EPA and others in determining the potential 

hazards and risks associated with various chemicals manufactured and used at high production volumes. 

Although not directly impacting environmental justice-related concerns, this information will enable the 

Agency to better protect human health and the environment, including in low-income and minority 

communities.

4.5 Executive Order 13045: Protection of Children from Environmental Health Risks and Safety 

Risks

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.

4.6 Executive Order 13132: Federalism 

Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999), requires EPA to develop an 

accountable process to ensure “meaningful and timely input by State and local officials in the 

development of regulatory policies that have federalism implications.” Policies that have federalism 

implications are defined in the Executive Order to include regulations that have “substantial direct effects 

on the States, on the relationship between the national government and the States, or on the distribution of 

power and responsibilities among the various levels of government” (64 FR 43255, August 10, 1999). 

The final rule establishes reporting and recordkeeping requirements that apply to manufacturers 

(including importers) and processors of certain chemicals. EPA has no information to indicate that any 

state or local government manufactures or processes the chemical substances covered by this action.

4.7 Executive Order 13175: Consultation and Coordination with Indian Tribal Governments 
Economic Analysis of SNUR for U.S. EPA Office of Chemical Safety and Pollution Prevention

Di-n-pentyl Phthalate (DnPP) 23 Economic and Policy Analysis Branch

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. 

4.8 Executive Order 13211: Actions that Significantly Affect Energy Supply, Distribution, or Use 

This rule is not subject to Executive Order 13211, entitled Actions Concerning Regulations That 

Significantly Affect Energy Supply, Distribution, or Use (66 FR 28355, May 22, 2001), because this 

action is not expected to affect energy supply, distribution, or use.

5. BENEFITS

A SNUN submission provides EPA with the opportunity to evaluate the intended use and, if necessary, to 

prohibit or limit that activity before it occurs. It allows the Agency to take immediate action to mitigate an 

activity that the Agency deems harmful to the environment or human health. The final SNUR allows EPA 

to evaluate the use of, or exposure to these chemicals and allow the Agency to take preventive action to 

limit or prohibit any Significant New Use. 

EPA requires additional information to fulfill its mandate under TSCA to fully assess the risks posed by 

the production, sale, and use of DnPP in the United States. A SNUN submission provides EPA with the 

opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it 

occurs. It allows the Agency to take immediate action to mitigate an activity that the Agency deems 

harmful to the environment or human health. The final SNUR allows EPA to evaluate the use of, or 

exposure to this chemical and allows the Agency to take preventive action to limit or prohibit any 

Significant New Use. EPA also expects the final rule may restrict future uses and thereby exposure to the 

chemical, as a company may choose modify planned uses of the chemical to not be subject to the SNUR, 

as opposed to submitting a SNUN. Therefore, the final SNUR may limit future exposure (e.g., worker, 

consumer) to the chemicals. 

Quantification of the benefits of the final rule will require more specific information about each user’s use 

patterns and preferences, as well as the changes in these patterns and preferences that will result from the 

additional information made available under the final rule. These data are not readily available and 

collecting such data will be cost-prohibitive.

A. INFLATORS AND WAGE RATES

This appendix describes the derivation of the fully loaded labor rates and inflation factors used in 

calculating costs of labor, materials, and other inputs. Costs presented in this report are in 2011 dollars.

A.1 Derivation of Loaded Wage Rates 

Unit labor costs are calculated by adding fringe benefits and overhead to the wage or salary to derive a 

fully loaded labor cost. The basic method is described in Wage Rates for Economic Analysis of the Toxics 

Release Inventory Program (EPA, 2002b). The resulting 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.

clerical Office and administrative support

Source: Employer Costs for Employee Compensation: Changes to NAICS and SOC, Table 2. ECEC Occupational 

Comparability between SOC and OCS (BLS, 2006a and 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, and clerical labor were taken from the 

Bureau of Labor Statistics (BLS) Employer Costs for Employee Compensation (ECEC) data,26 for 

December 2011, for manufacturing industries.27

The cost of fringe benefits such as paid leave and insurance, specific to each labor category, are taken 

from the same ECEC series. Fringe benefits as a percent of wages are calculated separately for each labor 

category. For example, for December 2011, the average wage rate for professional/technical28 labor was 

$38.48; the average fringe benefit was $19.64. Fringe benefits as a percent of wages were $19.64/$38.48, 

or approximately 51.0 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 

 

26 This follows the approach introduced in Economic Analysis of Expedited Significant New Use Rules for 65 Chemical 

Substances: EPA Docket OPPT-2003-0063 (EPAB, 2007b). 

27 Employer Costs for Employee Compensation Supplementary Tables December 2011. (BLS, 2012a). This follows the 

approach introduced in EPAB, 2007a. Earlier PMN SNUR economic analyses, such as EPA, 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.

28 This follows terminology introduced in EPAB, 2007b. 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, Comparing Current and Former Industry 

and Occupation ECEC Series (Weinstein, 2004).

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 2011 fully loaded wage for 

professional/technical labor is $38.48 × (1+0.5104 + 0.17) = $64.66.

Fully loaded costs for managerial and clerical labor are calculated in a similar manner, as shown in Table 

A-1.

A.1.2 Derivation of Labor Rates for EPA Staff

Agency labor costs are calculated based on annual Federal salaries for the Washington-Baltimore area 

published by the Office of Personnel Management effective January 2011 (OPM, 2011). The average 

salary for one FTE staff member is estimated as the salary for a GS-13 Step 5 employee.29

Multiplying the annual pay by an assumed loading factor of 1.6 to reflect Federal fringe benefits and 

overhead, the loaded annual salary of EPA staff was calculated to be $161,446. 

The Agency loading factor is from an EPA guide, Instructions for Preparing Information Collection 

Requests (ICRs) (EPA, 1992, page 30, footnote 9). The 60 percent assumption was labeled “the benefits 

multiplication factor” in the EPA Guide, but has been used in many EPA Office of Pollution 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)

 

29 The GS-13 Step 5 is consistent with ICR No. 0574.14 (12/18/2007), which covers PMN SNURs. Use of this grade level 

follows the approach introduced in EPAB, 2007a. That report represented a change from the earlier PMN SNUR economic 

analysis (EPA, 2003), which used an average of GS-12 Step 1 and GS-12 Step 10 salaries.

A.2 Derivation of Inflation Factors

Detailed information on the derivation of the inflation factors used is presented 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).30

“Starting year” indices in Table A-2 continue to be SIC-OCS based. Current year indices are NAICSSOC 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. 

 

30 BLS has been publishing the NAICS-SOC based ECI series since March 2001 and it became official in March 2006. The SICOCS 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.

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 Professional, and Related workers. 

2

Inflation factors are rounded; however, unrounded values were used in calculations.

3 Beginning with the report Economic Analysis of Expedited Significant New Use Rules for 25 Chemical Substances: EPA Docket 

OPPT-2009-0922 (EPA, 2011b) we began to use the not-seasonally adjusted CIU2010000120000I for private industry Professional, 

and Related workers, instead of SA CIS2010000W00000I for private industry white collar workers because BLS retired the “whitecollar” series.
