## Executive Summary This Economic Analysis estimates the potential costs of Significant New Use Rules (SNURs) covering 17 chemicals that have been the subject of TSCA premanufacture notices (PMNs) . Appendix A lists each regulated chemical’s generic or specific chemical name and Chemical Abstract Service Registry Number (CASRN) (if non- confidential) . The SNURs are being published under the rulemaking docket number EPA -HQ - OPPT -2011- 0942 as direct final rules . The SNURs define “Signif icant New Uses” that trigger EPA noti fication requirements . To submit a Significant New Use Notice or request a SNUR modification, a firm incurs a modest submission cost, plus costs of any additional data generated to support the submission . By avoiding a Significant New Use, a firm can avoid submission costs, but may incur other compliance costs . For example, it may incur costs associated with restricting chemical releases to water or preventing worker exposure . The options available to a firm considering the manufacture, import, and/or processing of a chemical covered under a SNUR, and the types of associated costs to the firm, are summarized in Table ES -1. Itshould be noted that the costs listed in Table ES -1 may be incurred for reasons other than the SNUR. The costs of avoiding a Significant New Use are attributable to the SNUR only if, in the absence of the SNUR, the firm would have adopted a different approach. For example, a SNUR may define any use other than that described in the PMN as a Significant New Use. If the PMN submitter would have conformed to the uses described in the PMN even without the SNUR, then any associated costs of adhering to the PMN uses would not be due to the SNUR. Costs to a PMN submitter of practices required by a TSCA Section 5(e) Consent Order would be attributable to the Consent Order, not the SNUR. If a processor would have workers wear gloves even without SNUR requirements, then the gloves costs would not be attributable to the SNUR. The costs in Table ES -1 are attributabl e to the SNUR only if the firm adopts a different approach due to the Significant New Use Rule.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 iii January 2012

**Option** 1 **Costs Quantified Costs per Che**  **mi cal**  **(2010$)** 2 1 Manufacture, import, or process in a way that avoids a Significant New Use, such as limiting water releases, engaging in PMN uses only, im porting only, limiting volumes, providing workplace protection, or providing hazard communications. All SNUR chemical s require ongoing recordkeeping . In addition, many SNUR chemicals may involve costs of complying with water release restrictions and foregoing non - PMN uses; these costs were not quantified for this report . Costs for worker protection and hazard communicati on apply to relatively few chemicals, but are quantified . Ty pically, annual costs for recordkeeping are under $1,155 . For the fe w SNUR chemicals where these apply, annual costs for worker protection may be $36,283 or more and for haz - comm is $1,056 .

2 Submit a request for mo dification or revocation of the SNUR (§721.185). Costs of submitting a request for mo dification or revocation, including costs of developing supporting data (e.g., testing, if needed). $5,802 submission cost plus any testing costs. 3 EPA receives very few such requests, typically 0 - 3 per year 3 Electronic submi ssion 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 electronically submitting a SNUN (including SNUN recordkeeping and user fee 4 ) plus ongoing recordkeeping . Rarely, a firm may choose to conduct toxicity or fate testing to support the SNUN, but such testing is not required by law. $8,302 submissio n cost (including SNUN recordkeeping and $2,500 fee) 4,5 plus ongoing recordkeeping costs of under $1,155 . EPA usually receives well under ten SNUNs in a year. Based on review

of recent SNUNs, it appears that firms rarely conduct toxicity or fate testing to support a SNUN (such testing wo uld be voluntary). 4 Petition EPA for an e quivalency determination to consider alternative controls to prevent release or exposure that are equivalent to those identified in the SNUR (§721.30). Costs of submitting an electronic request for equivalency determination. $5,802 one-time submission cost.

5 Do not manufacture, import, or process the substance except for R&D (the R&D exemption is covered in 40 CFR §721.47). Cost of profits foregone due to delaying or avoiding commercial activity that would otherwise be pursued . R&D recordkeeping costs if manufacture for R&D. Costs not quantified.

**Notes:** Section numbers refer to 40 CFR §721 (in the Code of Federal Regulations) . Costs come from Table 3 through Table 8 . 1 Firms may follow m

ultiple Options simultaneously 2 Quantified costs are attributable to the SNUR Significant New Use definition only if a firm would not otherwise follow the specified practices. $36,283 is the annual cost for dermal protection selecti on; impermeability testing, heavy- duty gloves, and a lo we r- cost respirator (see Ta ble 5) . Some firms may have export notification costs (see Chapter 3 of this report). 3 See Appendix D for costs of individual tests recommended in current and recent SNURs. 4 EPA charges a nominal flat fee of $2,500 for a PMN or SNUN submission . 5 SNUR chemicals not on the TSCA Inventory are “new” chemicals requiring a PMN, so some firm s may need to make a submission before commercial production or import, even in the absence of a SNUR (see Section 2.3 of this report) .Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 iv January 2012

## 1 **Introduction** This report presents the U.S. Environmental Protection Agency (EPA), Office of Chemical Safety and Pollution Prevention ’s (O CSPP ) ’s analysis of the potential costs incurred as a result of direct final Significant New Use Rules (SNURs) being promulgated for 17 chemical substances which have gone through premanufacture notice (PMN) review. 1 

### The SNURs are being published under the rulemaking docket number OPPT -2011 -0942 . Appendix A lists the generic or specific chemical name and Chemical Abstract Service Registry Number ( CASRN) (if non - confidential) for each PMN. 

### 1.1 **Statutory Au**  **th ority**  **and Significant**  **New Uses under the Proposed SNURs** EPA may promulgate a SNUR for a substance when ( 1) the substance is the subject of a section 5(e) Consent Order (40 CFR §721.160) , or ( 2) the Agency determines that activities other than those described in the PMN may result in significant changes in human exposure or environmental release levels and/or that concern exists about the substance’s health or environmental effects (40 CFR §721.17 0) . In contrast to PMN requirements, which apply mainly to manufacturers and importers (TSCA § 5(a)(1)(A), 40 CFR §720.22), the SNUR applies to processors as well as to manufacturers and importers ( TSCA § 5(a)(1)(B), 40 CFR §721.5). Each substance analyzed here was the subject of at least one premanufacture notice submitted under the Toxic Substances Control Act (TSCA), and is now being regulated as a result of PMN review . For the current rulemaking, 10 of the 17 chemicals have commenced commercial manufact ure or import and so are listed on the TSCA Inventory; they are no longer “new” chemicals. For chemicals in this type of rulemaking, SNUR requirements are sometimes based on past Consent Orders entered into with a PMN or SNUN submitter under TSCA Section 5(e) . For the current rulemaking, SNUR requirements for 2 of the 17 substances are based on prior Consent Orders. EPA promulgates a SNUR to designate specific activities involving the chemical substance that EPA has determined constitute a “ significant new use. ” No person may manufacture or process a chemical substance for a significa

nt new use, unless they submit a significant new use notice (SNUN) to EPA at least 90 days in advance. Examples of typical “ significant new uses ” that can trigger the requirement to submit a SNUN (if EPA has promulgated a SNUR applying these requirements to a specific chemical) include:

 Domestic manufacture in the United States  Manufacture of a particular aggregate or annual volume  Use other than that specified in the PMN  Releases to water resulting in a surface water concentration exceeding a specified amount  Handling the chemical without employing specified personal protective equipment (e.g., gloves, goggles, respirators) or hazard communication (haz- comm ) measures (e.g., label, MSDS, worker training) If EPA does not promulgate a SNUR for a given chemical , then these requirements would not apply (unless they apply to a PMN submitter via a §5(e) Consent Order) . If EPA has promulgated a SNUR containing these types of significant new use designations, as long as the person does not engage (nor intend to engage) in any activities defined by the SNUR as a significant new use, then that person may proceed to handle the chemical without submitting a SNUN. 1 This report covers chemicals that went through PMN review and are part of an expedited rulemaking. The relevant Office of Management and Budget Information Collection Request number is ICR No. 0574 (OMB Control Number 2070 - 0012). EPA also promulgates SNURs through conventional rulemaking that are covered by ICR No. 1188 (OMB Control Number 2070 - 0038).Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 2 January 2012



### 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 ass ociated with complying with the rule, and the costs to EPA of administering the rule. Types of industry costs analyzed include those for worker protection, hazard communication, testing, submission of required information , 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 previous economic analyses of SNURs, EPA identified those requirements under Subparts A, B, C, and D of 40 CFR §721 that may indirectly impose costs on manufacturers, importers, and processors of PMN substances (e.g., EPA, 1989 ). Some of these c osts, such as providing personal protective equipment under §721.63, were estimated in earlier SNUR economic analyses and are presented as part of this analysis . Resources were not available to quantify other costs, such as for limiting releases to water, avoiding uses not listed in the PMN, or keeping production below a specified level; they are described only qualitatively. Itwas not feasible within available resources to aggregate costs , or to estimate how often costs are actually incurred as a result o f SNURs , except for costs of SNUN submission s. 

### 1.3 **Organization of this Report** The remainder of this report estimates the quantified portion of costs potentially associated with SNURs such as those included in this rulemaking . Chapter 2 presents estimates of the costs that could be incurred by manufacturers, importers, and/or processors under the various SNUR options. Chapter 3 addresses export notification costs . Chapter 4 addresses costs to EPA of administering the SNURs, while Chapter 5 presents an analysis of other impacts, as required by various statutes and executive orders . Appendix A lists the chemicals that are subject to the proposed SNURs. Appendix B provides the wage rates and inflators used in this analysis . Other appendices give cost estimation details and references.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 3 January 2012



## 2 C **osts of a Significant New Use Rule (SNUR), by**  **Option** A SNUR specifies requirements that a firm must meet if it chooses to manufacture, import, or process a PMN chemical without engaging in a Significant New Use that would trigger notification to EPA . A SNUR also requires recordkeeping for anyone manufacturing, importing, or processing the SNUR chemical . A SNUR recommends testing, but does not require testing . EPA rarely receives results of tests performe d specifically to support a SNUN **.** Table 1 sets forth possible responses to a SNUR . A firm may select more than one course of action . For example, it may produce a chemical in a way that avoids a Significant New Use, while simultaneou sly submitting a Significant New Use Notice for a proposed new use . These options are described below along with their costs. **Table 1.**  **Summary of Compliance Options and Associated Costs**  **Potentially due to**  **a SNUR** 

**Option** 1 **Description of Costs**  1 Manufacture, import, or process in a way that avoids a Significant New Use, such as limiting water releases, engaging in PMN uses only, im porting only, limiting volumes, providing workplace protection, or providing hazard communications. All SNUR chemicals require ongoing recordkeeping . In addition, many SNUR chemicals may involve costs of com plying with water release restrictions and foregoing non- PMN uses; these costs were not quantified for this report . Costs for worker protection and hazard communication apply to relatively few chemicals, but are quantified . 2 Submit a request for modification or revocation of the SNUR (§721.185). Costs of submitting a request for modification or revocation, including costs of developing supporting data (e.g., testing, if needed). 3 Electronic submi ssion of a Significant New U se Notice (SNUN), indicating to EPA that the firm wo uld like to manufacture, import, or process the chemical for a Significant New Use as defined in the SNUR. Costs of electronically submitting a SNUN (including SNUN recordkeeping and user fee 4 ) plus ongoing recordkeeping . Rarely, a firm may choose to conduct toxicity or fate testing to support the SNUN, but such testing is not required by law. 4 Petition EPA for an e quivalency determination to consider alternative controls to prevent release or exposure that are equivalent to those identified in the SNUR (§721.30). Costs of submitting an electronic request for equivalency determination. 5 Do not manufacture, import, or process the substance except for R&D (the R&D exemption is covered in 40 CFR §721.47). Cost of profits foregone due to delaying or avoiding commercial activity that would otherwise be pursued . R&D recordkeeping costs if manufacture for R&D. **Notes:** Section numbers refer to 40 CFR §721 (in the Code of Federal Regulations) . Costs come from Table 3 through Table 8 . 1 Firms may follow multiple Options simultaneously 2 Quantified costs are attributable to the SNUR Significant New Use definition only if a firm would not otherwise follow the specified practices. $36,283 is the annual cost for dermal protection selecti on; impermeability testing, heavy- duty gloves, and a lo we r- cost respirator (see Ta ble 5) . Some firms may have export notification costs (see Chapter 3 of this report). 3 See Appendix D for costs of individual tests recommended in current and recent SNURs. 4 EPA charges a nominal flat fee of $2,500 for a PMN or SNUN submission . 5 SNUR chemicals not on the TSCA Inventory are “new” chemicals requiring a PMN, so some firms may need to make a submission before commercial production or import, even in the absenc e of a SNUR (see Section 2.3 of this report) .Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 4 January 2012



### 2.1 **Comply w ith SNUR Limits (Option 1)**  A firm can avoid engaging in a Significant New Use and submitting a SNUN by meeting all applicable SNUR requirements . The firm may also pursue this option temporarily by complying with SNUR restrictions while also pursuing other options such as making a submission to EPA . If it does avoid engaging in a Significant New Use (and if the chemical is on the TSCA Inventory or if the firm has already submitted a PMN), no notice to EPA is required. 2 

### Table 2 shows the types of requirements a firm must meet to avoid engaging in a Significant New Use . The Significant New Use designation in a SNUR for a specific chemical reflects either the use scenario described in the PMN for that chemical (what the submitter was already planning to do) or the requirements in the 5(e) Consent Order resulting from the PMN submission . Thus , it is likely that the typical PMN submitter will incur no added costs of com plying with the SNUR requirements so as to avoid a Significant New Use . However, if there is any export of these chemicals, there will be export notification costs that result from the TSCA Section 12 (b) requirements that are automatically triggered for chemicals regulated under TSCA Section 5 (see Chapter 3 for details). **Table 2.**  **Production and Use Restrictions/Requirements 40 CFR Reference**  **(Code of Federal Regulations)**  **Restriction/Requirement N**  **umber of**  **Chemicals Affected**  1 **Sample Costs Per**

See the recordkeeping discussion in Appendix C. **Source** : Costs are summarized in Table 3 , Table 4 , and Table 6 , and derived in Appendix C.

2 Under the Toxic Substances Control Act § 3(9), if a chemical is not on the TSCA Inventory, it is a “new chemical.” Prior to manufacture or import of a new chemical for general commercial use, a notice must be filed with EPA under Section 5(a)(1)(A) of TSCA (40 CFR §720.3 and 40 CFR §720.22).Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 5 January 2012



### The costs of meeting the haz -comm, protective equipment, and recordkeeping requirements are quantified for this report . Appendix C presents a more detailed derivation of these costs . The export notification costs are summarized in Chapter 3 . Complying with requirements to avoid a Significant New Use also may result in additional costs that affect a significant number of the chemicals, such as costs associated with limiting releases to water, that were not quantified for this report; these costs are also summarized below. **2.1.1 Hazard Communication**  

### Requirements **.** Each SNUR may require firms that manufacture, import, or process one of the PMN substances to implement a haz - comm program for the applicable chemical , or else submit a SNUN . For purposes of the economic analysis, it is assumed that each facility has in place a haz - comm program consistent with that required by OSHA’s Hazard Communication standard (29 CFR 1910; November 25, 1983). Much o f the haz - comm cost methodology used in this analysis came from a 1989 EPA report, Economic Analysis of Final Significant New Use Rules: General Provisions for New Chemical Followup ( EPA, 1989 ). The cost estimates provided here are for one chemical produce d at one site , assumed to have 25 exposed workers and roughly a 10,000 kilogram annual shipment volume . Higher volumes would increase costs, although not necessarily proportionately . The major elements of a haz - comm program that could apply to a SNUR chemi cal, based on the requirements in §721.72, are:

 Revision of the existing written haz - comm program to incorporate information about the chemical [§721.72(a)];  Creation of labels and application of labels to containers used for distributing the chemical in c ommerce [§721.72(b)];  Creation of labels or signage and posting of hazard data in areas of the facility where the chemical is used or stored [§721.72(b)];  Creation and distribution of material safety data sheets (MSDSs) [§721.72(c)]; and  Employee awareness training on where and how the chemical is used, the hazards associated and availability of hazard information about the chemical, and protective equipment and other measures in place to reduce and minimize exposure to the chemical [§721.72(d)]. **Costs .**  The annual costs of compliance with the haz- comm requirements for PMN substances subject to haz - comm requirements appear in Table 3. Further, the costs are for substances with full haz - comm requirements, and may overstate haz - comm costs

**2.1.2 Protection in the Workplace**  

### Requirements. Under 40 CFR §721.63, manufacturers, importers, or processors must comply with worker protection requirements as specified in the SNUR on the regulated chemical, or else submit a SNUN . The core components of the worker protection requirements include provision of personal protective equipment (PPE) such as gloves, goggles, protective clothing, and respirators. In some cases, EPA specifies the ty pe of PPE required . In other cases, EPA requires adequate dermal protection but does not specify particular PPE . Instead, it requires the employer to evaluate worker exposure conditions and hazards, and select appropriate PPE . Generally the employer is als o required to determine that dermal PPE is impervious to the PMN substance by one or both of the following methods : (1) perform impermeability testing on the PPE under the expected conditions of exposure, and/or (2) rely on equipment manufacturers' specifi cations . Employers not already providing adequate dermal protection would need to do so. **Costs.** Annual costs for worker protection items are shown in Table 4 below . The derivation of the sample minimum and maximum annual costs for worker protection is found in Table 5 . The costs of worker protection were originally e stimated in a 1989 EPA report, Economic Analysis ofFinal Significant New Use Rules: General Provisions for New Chemical Follow- Up (EPA, 1989 ), as a range of costs, depending on the assumed number of worker- days of exposure . This report us es the high end of the assumptions about worker- day exposure, updated to adjust for inflation . The estimates are for one chemical at one site with 25 exposed workers; actual costs would vary with the number of workers.

Future SNURs may list different choices . The citations in brackets refer to respirator types listed at 40 CFR . While the SNURs no longer reference the §721.63(a)(5) categories, costs in this analysis are based on cos ts estimated in 1997 for the §721.63(a)(5) categories. See Ta ble C - 10 for the crosswalk between respirator types in SNURs and in this table . The respirator “unit cost” is per worker . Total respirator costs include costs of the respirator plus the costs of any add - on items such as hoods, helmets, cartridges, filters, and caps, if these items are required for a particular respirator. **Source:** App endix C, Tables Table C -5 through Table C - 11 .Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 8 January 2012



### The costs of purchasing protective equipment are derived in Appendix C, and have been annualized based on the assumptions listed above regarding their use and lifetime in the workplace . Costs for evaluating hazards when PPE is not specified in the SNUR are based on estimates of the reasonable time required for a safety professional to perform such evaluations . Costs for conducting impermeability testing are based on consultation with PPE vendors, as described in Appendix C . Table 4 summarizes the annual costs associated with protection in the workplace, including the PPE itself, as well as selecting required dermal protection, and performing impermeability testing and/or evaluating manufacturer's information. Table 5 shows a sample of the minimum and maximum annual cost of workplace protection, assuming 25 workers who are exposed for 250 hours per year . The minimum cost includes the cost of heavy- duty butyl gloves, and 10 hours of an industri al hygienist’s time for dermal protection selection . The maximum cost is includes the cost of gloves, dermal protection, impermeability testing, and the annual cost of the least expensive respirator and filters for 25 workers . **Table 5 S**  **ample Costs of Workplace Protection Cost Element**  **Annual Cost (** **2010 $)**  **Example #1: Gloves and Dermal Protection Selection** Heavy- duty

### In cases where the SNUR specifies the type of protective gear, the estimates assume workers would not otherwise wear adequate protective equipment . To the extent that workers would otherwise be adequately protected (as a result of the company ’ s own safety program related to other chemical hazards, or to comply with OSHA ’ s PPE standards), these costs may be an overestimate of the actual costs. In some cases, the SNUR requires dermal protection but does not specify any particular gear, allowing regulated companies to make that determination . Table 4 shows costs of assessing needs and demonstrating impermeability . These cost estimates would reflect a situation where the dermal protection is already in place but the manufacturer must demonstrate that it is adequate . If companies also have to purchase additional protective gear, incremental costs attributable to the SNUR would include the added items . For example, if a firm already providing gloves and goggles determined that it would have to add protective clothing to avoid engaging in a Significant New Use, this would increase costs even if particular protective clothing is not specified in the SNUR.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 9 January 2012



### 2.1.3 **Recordkeeping** 

### Requirements

**.** Under 40 CFR §721.40, recordkeeping is required for SNUN submitters . This recordkeeping cost was included in the SNUN submission cost and is not separately estimated here. 3 

### In addition, the SNURs specify recordkeeping requirements for manufacturers, importers, and processors, by identifying paragraphs selected f rom 40 CFR §721.125(a) through (k) . These recordkeeping requirements apply even if the firm does not engage in a reportable New Use or make a submission to EPA, so long as it manufactures, imports, or processes the chemical . The recordkeeping requirements vary by chemical . For example, only chemicals that must establish a Hazard Communications program to avoid a Significant New Use would be required to keep records documenting their haz - comm program. (For firms producing under the R&D exemption, R&D recordkeeping would be needed. R&D recordkeeping costs were not estimated for this report.) SNUR recordkeeping requirements essentially involve copying and filing relevant records, including those related to manufacturing, importing, or processing volumes; shipment amounts and customer information; clothing impermeability determinations; the hazard communication program including labels and MSDS copies; compliance with disposal and water discharge limitations; and/or compliance with restrictions on volumes, nature of manufacture or use, or on the chemical’s physical form (powder, liquid etc.). **Costs .**  Annual costs for compliance with 40 CFR §721.125 recordkeeping requirements are low, but do potentially apply to all SNUR chemicals, and the recordkeeping could contin ue for years . Costs are presented in Table 6 and derived in Appendix C . They are estimated for one chemical at one site, and include technical and clerical labor time, photocopying charges, and costs for records storage. Table 6 summarizes recordkeeping costs by requirement at 40 CFR §721.125. The totals in Table 6 provide the cost if all recordkeeping requirements in paragraphs §721.125 (a) through (k) were required; this would seldom, if ever, be the case for a single chemical.

3 For example, OPPT’s Information Collection Request (ICR) for TSCA Section 5(a)(2) Significant New Use Rules for Existing Chemicals (Renewal), October 11, 2005, estimated SNUN recordkeeping costs at 5.67 hours (EPA, 2005, page 12).Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 10 January 2012

See Appendix C Table C - 14 for derivations. **2.1.4 Hidden Costs: p**  **roduction volume limits, limiting**  **releases to water ,**  **PM N uses,**  **import -**  **only, and disposal**  

### Several types of costs that may be incurred by complying with the significant new use designations are not quantified in this report, including . production volume limits, release s to water, disposal, and other use restrictions . For example:

 Keeping production volume below specified limits to avoid a Significant New Use could result in a decrease in profits; a potential “hidden” cost. A firm producing for sale may have to restrict its sales of the chemical. If the chemical is for internal use, it may have to substitute to a less cost - effective chemical.  A producer could incur costs of determining whether discharges to water would constitute a Signifi cant New Use and of limiting releases in order to avoid the Significant New Use.  Similarly, avoiding uses not listed in the original PMN could result in “hidden” costs of foregone profits if the firm cannot market the chemical for certain applications . If the firm wants to use the chemical for internal use, it may have to substitute to other chemicals or technologies that cost more or have lesser performance resulting in higher production costs.  Importing could be costlier than manufacturing a PMN substance in the United States. 

### 2.2 **Request Modification or Revocation of a SNUR (Option 2)** Under 40 CFR §721.185, EPA may modify or revoke a SNUR upon review of a submittal from a manufacturer, importer, or processor . Consequently, the second option for a firm is to request modification or revocation of the SNUR . According to New Chemical Program records EPA receives few modify/revoke requests (typically up to three per year) due to SNURs. This option may have some or all of the following associated costs:

 One -time costs of testing to develop health and environmental effects data for a chemical subject to the SNUR;  One -time costs of submitting a request for modification or revocation;Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 11 January 2012



###  Ongoing costs of complying with SNUR restrictions (Option 1 in this report) or of avoiding production while the modification request is being processed (Option 5) . The firm may also incur costs of complying with any SNUR restrictions that are not ultimately revoked or may incur hidden costs of avoiding production altogether. These costs are discussed below. **2.2.1 Costs of Developing and Submitting Testing Data**  

### 40 CFR §721.185(b)(1) requires that a modification request include “information sufficient to support the request.” For each PMN substance, the SNUR identifies health, ecological, and/or fate/transport/transformation testing that would help characterize the risks associated with the substance . However, there is no requirement for a requester to perform the recommended tests or even to perform testing at all . Itis possib le that some of the recommended tests, or other tests, would be performed by the submitter to support a request for modification and revocation of a SNUR . For informational purposes, costs for various tests recommended in SNURs over the years are listed in Appendix D . If no additional testing is performed to support a modification request, costs may be similar to costs of a SNUN

– discussed later in this section

– minus the user fee. Table 7 below provides an example of potential costs if a firm were to perform a standard set of basic ecotoxicity tests to support a request to modify or revoke a SNUR . **Table 7.**  **Sample Costs of Recommended Testing**  **Test Guideline Test description**  **Estimated Cost (** **20 10**  **$) Ecotoxicity Base Set**  OPPTS 850.5400 Algal Toxicity, Tiers I and II $18,480 OPPTS 850.1010 Daphnid Acute Toxicity $15,293 OPPTS 850.1075 Fish Acute Toxicity $21,076 **Sample TOTAL Testing Cost: $54,848**  **Source :**  Costs are from Table D -1 **2.2.2 Costs for Submitting a Request for Modification or Revocation of a SNUR**  

### The costs associated with submitting a request for modification and revocation of a SNUR (or of submitting a SNUN) are estimated to be similar to the costs for preparing a PMN submission, except that there is no user fee for the modify/revoke request . 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 (CMA, 1991), which became the American Chemistry Council . The burden associated with PMN submission and preparation has been adjusted to reflect burden reductions resulting from the 2009 final PMN Electronic ReportingEconomic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 12 January 2012



### (ePMN) Rule that requires the electronic submission of all TSCA section 5 notices. 4 

### Electronic submission of SNUN forms is expected to remove all clerical burden associated with preparing a SNUN (EPA, 2009a, p.7) . In addition , electronic submission is expected reduce all recordkeeping burden associated with SNUN submissions by fifty percent . Because, the recordkeeping burden for PMNs was not estimated separately, for the purposes of this report we assume this burden reduction is captured in the removal of all clerical burden. 5 

### In the 1994 EPA report, the average effort required to prepare and submit a PMN was 95 to 114 hours . This burden is reduced to 83 to 100 hours after accounting for the ePMN savings (EPA, 2009a) . This included recordkeeping for the submission, but the recordkeeping cost was not broken out . For this analysis, the costs of a preparing a SNUN were derived using the averages of the hours for each type of labor from the 1994 report, after adjusting for the ePMN savings . The method of calculating hourly loaded labor costs is described in Appendix B . **2.2.3 Other Costs**  

### EPA’s review of the submitter ’ s request may cause delays in the start of manufacturing or processing activities . Such delays could cause the company to forego opportunities to earn profits for the duration of the review period . Alternatively, the submitter may elect to produce under the constraints of the SNUR during the review period, so as to avoid a Significant New Use . EPA may not revoke all SNUR provisions as a result of the request . If the company is allowed to continue production and chooses to do so, it would bear costs of complying with any SNUR restrictions that are not revoked . Costs of complying with SNUR restrictions pending EPA modification or revocation were discussed under Option 1.

4 Economic Analysis of Ex pedited Significant New Use Rules for 2 5 Chemical Substances: EPA Docket OPPT - 2009- 092 2, wa s the first report to consider the burden reductions resulting from electronic submission of SNUN forms and requests for equivalency determination. Previously, all b urdens were based upon 1994 paper submission estimates. 5 The Economic Analysis of the Premanufacture Notification Electronic Reporting Final Rule (EPA, 2009 a) estimates 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, which include the burden for recordkeeping ( EPA, 1994 , p. III - 14) . T hese burden estimates are based on the recordkeeping burden for polymer exceptions and not the recordkeeping burden associated with PMN submissions . Therefore , for this analysis we assume that any reduction in recordkeeping burden is captured in the reduction of the clerical burden, and we do not consider the one hour recordkeeping burden from the ePMN EA to avoid double counting .Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 13 January 2012

### The total costs associated with requesting a modification or revocation of a SNUR include the costs of generating new supporting data plus the administrative cost of preparing the submission . 

### 2.3 **Submit SNUN (Option 3)** Under 40 CFR §721.5, manufacturers, importers, or processors who would like to undertake a Significant New Use of a substance listed in a SNUR are required to submit a Significant New Use Notice (SNUN) at least 90 days before the firm plans to commence the manufacture, import, or process ing of the substance . For example, they could submit a SNUN if they wish to produce above the volume limit listed in the SNUR for a given chemical, since any production beyond that volume would be defined as a Significant New Use. The SNUN provides EPA with the opportunity to evaluate the intended use and, if necessary, to prohibit or limit that activity before it occurs . The notice form used to submit a SNUN is the same as that for a PMN, and the costs of submitting a SNUN are estimated based on the costs incurred to submit a PMN. This option could have the following costs:

 One -time costs of the SNUN and $2,500 user fee. (However, in some cases, a notification may be needed for reasons other than the SNUR; see Section 2.3.1 below.)  Ongoing costs of complying with SNUR restrictions to avoid engaging in a Significant New Use (Option 1 in this report) or of avoiding production while the SNUN is being processedEconomic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 14 January 2012



### (Option 5); costs of recordkeeping , and of complying with any restrictions resulting from the SNUN review.  Rarely, the SNUN submitter may elect to perform some of the testing recommended in the SNUR as a way to characterize effects of a chemical . These tests are not mandatory , and firms do not usually conduct testing to support a SNUN, so any such costs are likely to be zero or low. The assumption regarding testing is based on an analysis of the 18 SNUNs submitted over a three -year period, from 20 05 through 200 7 . A list of human health tests submitted to EPA with PMNs and SNUNs was also available from a confidential database maintained by EPA ’s O ffice of Pollution Prevention and Toxics Risk Assessment Division . Only one SNUN described toxicity or environmental fate testing that seemed reasonably likely to have been performed to support a SNUN . In that case, two relatively low- cost tests (fish acute toxicity and daphnid acute toxicity) may have been conducted to support a SNUN, although it is also po ssible that the testing was done for some other reason not apparent in the SNUN itself . A substantial portion of the SNUNs did provide or reference test results . However, in almost all cases, the testing appeared to have been conducted for reasons other than a SNUR . For example, the SNUN might include laboratory reports that had already been submitted for a PMN for the same chemical . **2.3.1 SNUR “New” Chemicals**  

### If a SNUR chemical is not on the TSCA Inventory and a potential manufacturer or importer has not yet f iled a PMN, submission costs may be incurred but are not attributable to the SNUR. All SNUR chemicals in this rulemaking were the subject of at least one PMN. For PMN chemicals to be added to the TSCA Inventory, manufacturing (or import) must have commence d, with notification to EPA through a Notice of Commencement, or NOC . Thus, SNUR chemicals not yet in commercial manufacture (or import) are not on the TSCA Inventory . They legally remain “new” chemicals subject to PMN requirements. For “new” chemicals, firms who have not yet submitted a PMN must notify EPA 90 days before manufacturing/importing the chemical for commercial purposes . This submission is still designated a PMN but may contain information demonstrating the submitter intends to engage in a signi ficant new use . Either way, the firm uses the same submission form and provides the data listed at 40 CFR §720.45 . Consequently, for this special situation, the submission cost is incurred due to PMN requirements, not due to the SNUR . (See EPA ’ s 1997 Chemistry Assistance Manual for Premanufacture Notification Submitters for an overview of New Chemicals requirements [EPA, 1997]). **2.3.2 Ad**  **vance Compliance Exemption** 

### Another option available to firms before the SNUR is promulgated is to seek an advance compliance exemption under 40 CFR §721.45(h) . The submission cost for this option is the same as that for a SNUN, but by negotiating an advance compliance agreement with EPA a firm might diminish any loss of profits due to delay . This option is not available after the SNUR is promulgated. **2.3.3 Costs for Submitting a SNUN**  

### As with Option 2 above (Request Modification or Revocation of a SNUR), the costs for submitting a SNUN are estimated to be equivalent to the costs of completing a PMN submission . If the SNUN is submitted at the same time as a request to modify a SNUR (Option 2), the added cost would be less thanEconomic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 15 January 2012



### shown here due to overlap in information in the two submissions . Table 8 shows the costs of preparing a SNUN . **2.3.4 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 unreasonable 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. Subsequent regulatory action may be a Consent Order under TSCA Section 5(e). Assessments of costs and benefits for a Consent Order would be limited, similar to those supporting PMN reviews leading to Consent Orders , in contrast to the in - depth benefit- cost analyses prepared under some other TSCA Sections. The description above was adapted from text in Economic Analysis of the Significant New Use Rule for Chloranil, January 8, 2008 , Section 2.4; and Economic Analysis of the Final Significant New Use Rule for 183 Perfluoroalkyl Sulfonates , August 20, 2007, Section 3.4 . Both reports are from the U.S. EPA Office of Pollution Prevention and Toxics, Economic and Policy Analysis Branch . The nature of the follow-up regulatory action and benefit/cost analysis may differ between SNUNs for newer chemicals submitted as a result of a direct final rulemaking such as this one, and SNUNs for older chemicals such as chloranil and most p erfluoroalkyl sulfonates . 

### 2.4 **Request Equivalency Determination (Option 4)** Under 40 CFR §721.30, EPA may review applications from facilities who propose alternative methods of controlling or preventing exposures or releases to those specified in the SNUR . In these cases, EPA evaluates the alternatives using an abbreviated review process . As shown in Table 8 , the costs of submitting an equivalency determination request are expected to be the same as those for submitting a SNUN except that no user fee is required. For this option the EPA review period is 45 days compared to 90 days for a SNUN , therefore any potential loss of profits due to delays may be less than for a SNUN under Option 3. In addition to the costs of submitting the equivalency determination request, each submitter will also incur costs to develop data to support the request . H owever, total costs of the equivalency option should be no more than the costs of complying with controls in the SNUR to avoid a significant new use -- for example, controls related to workplace protection or environmental release . Otherwise, presumably there would be no incentive for the submitter to choose this alternative . Finally, to produce the chemical following EPA review, the submitter would incur costs from recordkeeping and from any restrictions not waived (see Option 1).Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 16 January 2012



### 2.5 **Decide Not to Produce Che mical (Option 5)**  Some firms may find that the costs of meeting the SNUR requirements and/or restrictions (Option 1) or preparing a SNUN or other submission (Options 2, 3, or 4) are financially unattractive . In these cases, the firm could choose not to manufacture, import, or process the PMN substance. While this option avoids the costs of meeting the specifications in the SNUR or submitting a request for some alternative, it entails the “hidden” cost of the profit that will be foregone as a result of not engaging in the commercial activity originally planned. For example, if the firm does not produce the SNUR substance, then it will forego the profit it would have achieved by producing it . That foregone profit is a potential “hidden” cost of Option 5 . Simila rly, if the firm would have used the SNUR substance in the production of another product and must substitute to a more costly substance, it will incur those additional costs of production . If the firm elects to produce for R&D purposes only, it may have co sts associated with R&D recordkeeping attributable to the SNUR. Firms that exercise Option 5 may still incur export notification costs, if they export any existing stockpiles of the product . This cost is quantified in Chapter 3 below. 

### 2.6 **Summary**

**of Costs for Each Option** Table 1 , above, gave an overview of compliance options . Table 3 through Table 6 summarized the quantified portion of potential costs of either following restrictions to avoid engaging in a Significant New Use, or of making a submission to EPA . Table 7 presented sample testing costs . Costs are for one chemical at one site, and

– where volume is relevant

– are based on standard assumptions that include 25 exposed workers per site and, for haz- comm costs, annual shipments of about 10,000 kilograms per site . Costs are not otherwise adjusted for the nature of the chemical or process, volume, location, or other firmspecific or chemical - specific factors. As mentioned above, costs are estimated for one chemical at one site, not for aggregate production . Resources were not available to estimate aggregate costs . Among other things, it is not known how many firms are affected by the SNURs. EPA receives a handful of Significant New Use Notices per year due to SNURs. However, if a SNUR chemical is on the TSCA Inventory, a firm may use the chemical in a way that avoids a Significant New Use (Option 1), and never make a submission . Itis not known how many firms are affected but do not make a submission . Also, it is not known whether firms avoid the chemical altogether specifically due to the SNUR . However, at least for the years immediately following SNUR promulgation, these numbers are likely to be small . This is because the chemicals in this type of SNUR rulemaking are still relatively new

– as Appendix A indicates, most were submitted to EPA as PMNs in the past four Federal fiscal years – and, in addition, often have confidential chemical identities.

 For firms manufacturing , importing, or processing within SNUR restrictions to avoid a Significant New Use (Option 1), quantifiable costs can range from a bout one thousand dollars (if the only added cost is for recordkeeping) to over $ 35 ,000 per chemical if the firm must add worker protection measures such as gloves, protective clothing, and respirators that it would not otherwise use . Most chemicals are also subject to costs that could be significant but are not quantified in this report, such as restrictions on releases to water or on other aspects of use .  For submissions to EPA (Options 2, 3, and 4), the basic one -time submission cost is estimated at $5,802 , including recordkeeping for the submission . For the SNUN (Option 3), EPA also collects a $2,500 fee.  One objective of the rule is that EPA will be a ble to regulate prospective manufacturers, importers, or processors of a listed chemical substance before the described significant new useEconomic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 17 January 2012



### of that chemical substance occurs, provided that regulation is warranted pursuant to TSCA sections 5(e), 5(f), 6 or 7 . Consequently, after submitting a SNUN, the firm may need to comply with restrictions as a result of the SNUN review process, possibly leading to further costs similar to those in Option 1.  Rarely , f

irms may choose to perform toxicity and/or environmental fate testing to support a SNUN (Option 3) . S uch testing is not mandatory . C osts for such testing are expected to be zero for most SNUNs and expected to be l ow for the few SNUNs for which a submitter might voluntarily perform such testing.  Companies that might have manufactured, imported, or processed a chemical in the absence of the SNUR may incur “hidden” costs, such as loss of profits from delayed or foregone sales, if they avoid the chemical altogether (Option 5) . These costs were not quantified.  Companies may incur costs from more than one Option, for exam ple if they tem

porarily produce in conformance with SNUR restrictions while submitting a SNUN and waiting the required 90 days plus any extensions . For some firms, costs may be attributable to EPA’s New Chemicals review process, but not to the SNUR itself . For example, a firm may already be bound by a TSCA Section 5(e) Consent Order following review of its PMN, so that the SNUR based on the 5(e) order imposes no added costs for that firm . As another example, in rulemakings where a SNUR chemical is not on the TSCA Inventory, firms that have not yet submitted a PMN must submit one to EPA before commercial production/import, with or without the SNUR (see Section 2.3, SNUR “New” Chemi cals) . If the SNUR reflects the PMN use scenario, and the PMN submitter would stick to the PMN uses even in the absence of a SNUR, then there would be no added costs for the PMN submitter attributable to the SNUR . Also, firms may also incur worker protection, haz - comm and other costs for reasons other than the SNUR, so that SNUR requirements may impose no added costs. 6

6 Earlier SNUR economic analyses calculated possible haz - comm, worker protection, testing, and other costs for each PMN chemical ( EPA, 2007b , Tables 9, 10, D - 4) . The chemical - specific tables were dropped from a later SNUR economic analysis ( EPA, 2007c ) . They refle cted SNUR requirements and “recommended” testing, but were not otherwise tailored to the particular situation, and so were unreliable predictors of actual SNUR costs.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 18 January 2012 

## 3 E **xport N**  **otification C**  **osts** 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 requirement7 

### 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 export notifications, EPA first estimated the average annual number of export notifications made by an exporter, in Section 3.1. EPA then derived the annual and per notification burden associated with preparing and submitting an export notification, in Section 3.2. 8 

### 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 uses, manufactures, 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 200 9 TSCA Section 12(b) ICR, 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), with updating for inflation . 

### 3.1 **Estimated Number of An**  **nual 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 . A notification is typically no more than one page per chemical/country combination, and one notification mailing often include s multiple chemicals and/or destination countries. 10 

### The percent of notificati ons due to PMN SNURs 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. 

### 3.2 **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 7 On November 14, 2006, EPA revised the export notification requirement for chemicals sub ject 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). 8 Beginning with this report (Economic Analysis of Expedited Significant New Use Rules fo r 2 5 Chemical Substances: EPA Docket OPPT - 2009- 0922 ) , the cost per notification is presented as well as the cost for the average submitter making export notifications. 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 estimated 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.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 19 January 2012



### the cost to the exporter of compiling a list of their products tha t 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 b ased on the average burden per firm making notifications . Exporters making more notifications per year may benefit from economies of scale and have lower costs per notification; those making fewer notifications may have higher costs per notification. **3.2.1 Estim**  **ated 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, 2009) . The estimated per- shipment and annual mailing costs incurred by individual submitters are detailed in Table 9 . **Table 9.**  **Derivat ion of Total Mailing Cost for 12 Notices**  **Postal Service Cost**  Registered mail, regular, with $0 declared value $10.60 Return receipt, requested at time of mailing (receive by mail) $2.30 Postage, regular First Class, up to 1 ounce $0.44 **Cost per export notice**  **- Subtotal**  **$13.34** × 12 **Total Mailing Cost for 12**  **Notices $160.08**  **Source:** Mailing rates are from the US Postal Service web site as of April 2010 (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, 200 7 c, Table 8 ). **3.2.2 Compile and Maintain the List of Products**  

### Since TSCA §12(b) information collection activity has been in place for over 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 200 companies were near the lower burden estimate of 2 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 × 

### 200 firms plus 24 hours × 

### 100 firms), or an average of about 9.3 hours of technical time per firm per year for 12 notifications per year (EPA, 2009b ).Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 20 January 2012

**3.2.3 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 f

or 12 notifications per year (EPA, 2009b ). **3.2.4 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 6 hours for 12 notifications (EPA, 2009b). The burdens and associated costs for each notification activity are provided in Table 10 below . **Table 10.**  **TSCA 12(b) Export Notification Cost per Notification**  **Technical Clerical**  **Total** $/Hr Hours 2010$ $/Hr Hours 2010$ 2010$ Hours Com pile list $61.71 9.3 $574 -- -- -- $574 9.3 Write letter $61.71 1 $61.71 -- -- -- $62 1 Check order and send notice -- -- -- $28.98 6 $174 $174 6 Mailing cost 1

## 4 A**gency C**  **osts** This SNUR is expected to generate Agency costs for both SNUN review and processing , and export notification processing . Because it is unknown how many SNUNs and export notifications will be submitted as a result of this rulemaking, all Agency costs are estimated at the per- case level and are not aggregated to estimate the total Agency burden . Section 4.1 describes the burden to the Agency of reviewing and processing a single SNUN submission . Section 4.2 derives the Agency burden of processing and reviewing export notifications. 

### 4.1 **SNUN Processing Costs** EPA’s costs to review and process industry submissions (SNUNs, requests to modify or revoke the SNUR, and requests for equivalency determinations) are assumed to be the same as EPA costs to review PMNs and are presented in Table 11. Costs to review and process industry submissions

– SNUNs, requests to modify a SNUR, and requests for equivalency determination

– are assumed to be similar to EPA costs to review PMNs. 11 

### The list of review steps, estimates of staff -year full -time equivalents (FTEs), 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 SNUN 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. 12 

### The ePMN rule affects SNUN submissions and requests for equivalency determination, but not requests to modi fy or revoke a SNUR . However, for simplicity, this analysis continues to assume that Agency per- submission costs are the same for all three types of submissions . Electronic submission of SNUN forms is expected to reduce Agency burden by 16.5 percent (EPA, 2009a, p.28). The GS levels used for Agency staff reflect the judgment of Agency staff familiar with the PMN/SNUN review process . The salary of a Full Time Equivalent EPA staff was calculated using GS - 13 Step 5 salary data (OPM, 2010) . The original PMN cos t estimates were for GS 12 and were presented as low and high estimates, based on the most junior (Step 1) and the most senior (Step 10) GS - 12 pay rates, respectively . However, this analysis uses the higher GS - 13 staff level and, for simplicity, a single intermediate pay rate (Step 5) within that GS level . A loading factor of 1.6 was applied to the salary to reflect fringe benefits and overhead (EPA, 1992) . The loaded salary calculations are described in Appendix B. For each review step, the “EPA staff” co st is calculated by multiplying the number of FTEs (in the first column) by the fully loaded average 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, inflated from 1993 prices, as explained in Appendix B . The Percent of Cases is a weighting factor applied to reflect the fact that not all chemicals require each review step . For exampl e, 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 is submitted with a SNUN than woul d 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 Unweighted 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 f or burden savings generated electronic submission . This calculation yields total Agency costs for submission review and processing shown in Table 11.Draft Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 23 January 2012

### 4.2 **Export Notification Processing Burden**  Under TSCA Section 12(b), exporters must notify EPA if they intend to export chemicals sub ject to SNURs, as described in Chapter 3 above . 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 US embassies (EPA, 2009b) . (S ee Table 9 for the cost of mailing one notification) . The third task is comprise d of EPA staff response s 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, notification s EPA will receive or send as a result of the current rulemaking, the costs to the Agency are presented per activity . 13 

### The burden for the first two Agency activities is provided in Table 12 below . To estimate the Agency cost, hourly burden s are multiplied by the loaded wage rate of a GS - 13, Step 5, which is derived in Appendix B . **Table 12**  **: TSCA 12(b) Export Notification Cost: Agency Burden**  **per Activity (2010**  **$) Agency Activity**  **Hours per**

## 5 A**dditional A**  **nal ys**  **es** This chapter presents additional analysis of other potential impacts of this rulemaking, as required under various statutes and executive orders. 

### 5.1 **Regulatory**

**Flexibility A ct (RFA** **)** The Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et. seq.), as amended by the Small Bus iness Regulatory Enforcement Fairness Act, requires regulators to consider the impact of regulations on small entities, in particular small businesses . EPA's experience to date is that, in response to the promulgation of SNURS covering over 1,000 chemicals , the Agency receives only a handful of notices per year . For example, the number of SNUNs was four in Federal fiscal year in 2005, eight in FY2006, six in FY2007, eight in FY2008 , seven in FY2009 , and one in FY2010 . 14 

### , 15 

### During this six -year period , three small entities submitted a SNUN . 16 

### The criteria for 'small business' was that the company checked the box on the PMN form, page 2, stating that it was a small business for the purpose of paying the $100 fee instead of the normal fee . 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 use 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 . However, a 1989 analysis suggested that few small businesses would be affected by SNURs for chemicals that have undergone PMN review . The 1989 report estimated that 9 percent of firms subject to SNURs would be small businesses, based on the portion of PMN submitters who were small businesses ( EPA, 1989 ). The threshold to be considered a “small business” was $40 million in sales, which is consistent with the definition used at 40 CFR §700.43 to set PMN fees. Past bona fide submissions also suggest that few firms other than possibly some PMN submitters will be affected. 17 

### EPA has received few bona fides indicating interest in manufacturing or importing chemicals subject to past SNURs . EPA also has received few public comments during rulemaking on SNURs covering PMN chemicals . For example, a SNUR published in the spring of 2003 covering 62 chemicals resulted in industry comments on only three PMNs, none from small businesses (EPA, 2003b ). It remains possible that some small businesses are affected by SNURs 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 small expense of keeping records and/or of changing workplace practices to comply with 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, but EPA expects them to be low . This is because SNUR chemicals are unlikely to be central to a

The counts include both “valid” and “invalid” SNUNs . SNUN numbering is according to Federal fiscal year, ending September 30. 15 FY 2010 count is from a July 20, 2011 email from Stephanie Suazo, EPA Office of Pollution Prevention and Toxics, to Kimberly Wilson, Abt Associates . 16 February 5, 2009 email from Carol Rawie, EPA Office of Pollution Prevention and Toxics to Tulika Narayan and Kimberly Wilson, Abt Associates and reviews of SNUN submissions on April 8, 2010 by Abt staff. 17 Bona fides are submitted to EPA by manufacturers and importers to determine a chemical's TSCA Chemical Inventory and regulatory statusEconomic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 26 January 2012



### firm’s business because they are relatively new and few compared to the many thousands of chemicals on the TSCA Inventory. Based on these considerations and on the limited data available, EPA expects that any com pliance with a SNUR will not have a significant economic impact on a substantial number of small entities. 

### 5.2 **Unfunded Mandates Reform A ct (UMRA** **)** EPA has determined that this regulatory action does not impose any enforceable duty, contain any unfunded mandate, or otherwise have any effect on small governments subject to the requirements of sections 202, 203, 204, or 205 of the Unfunded Mandates Reform Act of 1995 (Public Law 104 -4). 

### 5.3 **Paperwork Reduction A ct (PRA** **)** According to the Paperwork Reduction Act (PRA), 44 USC 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 Office of Management and Budget (OMB) approval under the PRA, unless it has been approved by OMB and displays a currently valid OMB control number . The information collection requirements related to this action have already been approved by OMB pursuant to the PRA under OMB control number 2070 -0012 (EPA, 2007a). This action does not impose any additional burden requiring OMB approval . 

### 5.4 **Executive Order 12866, Regulatory Planning and Review**  Executive Order 12866, Regulatory Planning and Review, requires OMB review for rules with an impact on the economy of $100 million or more, or with any other potential significant impact . OMB has previously determined that these types of SNURs are not a “significant regulatory action” that would require OMB review under this Executive Order. 

### 5.5 **Executive Order 13132, Federalism** Executive Order 13132, 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.” This action will not have a substantial direct effect on States, on the rel ationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132, entitled Federalism (64 FR 43255, August 10, 1999). 

### 5.6 **Executive Orde r 12898, Environmental Justice**  This action does not involve special considerations of environmental justice related issues as required by Executive Order 12898, Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations (59 FR 7629, February 16, 1994). 

### 5.7 **Executive Order 13045, Protection of Children** Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks (62 FR 19885, April 27 , 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 these SNURs will be less than $100 million and therefore no analysis of such impacts on children is required.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 27 January 2012



### 5.8 **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 b ecause it is not expected to have substantial direct effects on Indian Tribes. 

### 5.9 **Executive Order 13211, Energy Supply, Distribution, or Use**  This rule is not subject to Executive Order 13211, entitled Actions Concerning Regulations That Significantly Affect E

nergy Supply, Distribution, or Use (66 FR 28355, May 22, 2001), because this action is not expected to affect energy supply, distribution, or use.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 1 January 2012

## I **nflators and**  **W age**  **R ates**  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 2010. 

### 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 B-1. Costs are calculated for several labor categories: Managerial, Professional/ Technical, Clerical, Production Workers , Industrial Hygienists, 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. **2.0.1 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, 18 

### for December, for manufacturing industries. 19 

### The cost of fringe benefits such as paid leave and insurance, specific to each labor category, are taken from the same ECEC series . Fringe benefits as a percent of wages are calculated separately for each

18 This follows the approach introduced in Economic Analysis of Expedited Significant New Use Rules for 65 Chemical Substances: EPA Dock et OPPT -2003 - 0063 (EPA, 2007b). In earlier PMN SNUR economic analyses, such as EPA, 2003a, wage rates for production workers came from the BLS National Employment, Hours, and Earnings, Average Hourly Earnings of Production Workers, while fringe benefits were taken from the ECEC data. Here, as in EPA, 2007b , both wages and fringes for production workers come from ECEC data, for better consistency with the method of estimating labor costs for other labor categories. 19 Em ployer Costs for Employee Compensation Supplementary Tables December 20 10. (BLS, 2011a). This follows the approach introduced in EPA, 2007b. Earlier PMN SNUR economic analyses, such as EPA, 2003a, 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.Draft Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 B-2 January 2012



### labor category . For example, for December 2010 , the average wage rate for professional/technical20 

### labor was $36.93 ; the average fringe benefit was $18.50 . Fringe benefits as a percent of wages were $18.50/$36.93 , 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 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 Dec ember 2010 fully loaded wage for professional/technical labor is $36.93 × (1+0. 5009 + 0.17) = $61.71 . Fully loaded costs for managerial, clerical, and production labor are calculated in a similar manner, as shown in Table B -1. **2.0.2 Derivation of Labor Rates for Industrial Hygienists**  

### For industrial hygienists, wages were based on another BLS data series, Occupational Employment Statistics [OES

], National Indus try-Specific Occupational Employment and Wage Estimates . OES data were used because ECEC data were not available for very specific occupations . However, the OES data covers only wages, not fringe benefits . Therefore, the Industrial Hygienist fringe benefits continue to be based on ECEC data. 21 

### The wage rate for Industrial Hygienists is a weighted average of the hourly mean wage for Occupational Health and Safety Specialists, Standard Occupational Classification (SOC) 29 - 9011, and Occupational Health a nd Safety Technicians, SOC 29 - 9012, in Manufacturing . The wage rate for each occupation was weighted by employment for the occupation . The North American Industry Classification System (NAICS) codes for Manufacturing are 31, 32, and 33 (BLS, 2005) . The cal culations are shown in Table B-2. As with other labor categories, the fringe benefits factor came from the BLS Employer Costs for Employee Compensatio n Supplementary Tables December 2010 (BLS, 2011a) . Benefits for “professional specialty and technical” occupations were used, and loaded wages were calculated as for other types of labor . An additional loading factor of 17 percent of wages was applied for overhead . Calculations are shown in Table B -1.

20 This follows terminology introduced in EPA, 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 pro cess, the “Professional specialty and technical” category became the “Professional and related” category. However, the coverage of the old and new occupational groups is approximately the same. See the BLS article, C omparing Current and Former Industry and Occupation ECEC Series (Weinstein, 2004 ). 21 This follows the approach for calculating Industry Hygienist wages introduced in EPA, 2007b and is a change from the method used in earlier PMN SNUR economic reports such as EPA, 2003a, which used data from a 19 97 professional journal salary survey.Draft Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 B-3 January 2012

**2.0.3 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 e ffective January 2010 (OPM, 2010). The average salary for one Full Time Equivalent (FTE) staff is estimated as the salary for a GS - 13 Step 5 employee. 22 

### 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 su pporting ICR No. 1139.06 (EPA, 2000) , with the following explanation: “T he 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.” (EPA, 2000 )

22 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, 2003a), which used an average of GS - 12 Step 1 and GS - 12 Step 10 salaries.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 B-4 January 2012

### Derivation of Inflation Factors Costs of equipment and supplies were inflated using the Consumer Price Index

– All Urban Consumers; wages were inflated using the appropriate Employment Cost Index (ECI) . Where both labor and equipment/supplies were involved, we used the inflation factor corresponding to the dominant cost category23



### . For example, test costs include a mix of labor, equipment, and supplies . Assuming that the largest component of test costs comes from labor, we used the ECI for private industry, all workers . Complete information on the derivation of the inflation factors used is given in Table B -3 below. 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 P lans” (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 (NAIC S) 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 Decem ber 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

23 Prior SNUR economic analyses used the seasonally adjusted E CI for the total compensation , private industry white collar workers (Series ID CIS2010000W00000I) to inflate export notification and Agency extramural cost . However, in 2008 B LS retired both the “white - collar” and “blue - collar” series (BLS, 2008, p. BLS - 45) . T herefore , beginning with the report , Economic Analysis of Expedited Significant New Use Rules for 2 5 Chemical Substances: EPA Docket OPPT

- 2009-092 2 , the “white - collar” series was replaced with the not seasonally adjusted E CI for total compensation of private industry professional and related workers (Series ID CIU20100001 20000I ). The “professional and related workers ” series wa s chosen because it is the only series with continuous data since 1985 , and the majority of export notification and Agency extramural activities are performed by professional and technical labor.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 B-6 January 2012



### B- 3 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). 24 

### “Starting year” indices in Table B - 3 continue to be SIC - SOC 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 .

24 BLS has been publishing the NAICS - SOC based ECI series since March 2001 and it became official in March 2006. The SIC OCS based series and NAICS-SOC series have different series ID numbers, even when they describe essentially the same population. For examp le 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

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 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 We began using the ECI for Private Industry All Workers in EP A, 2007b , to better reflect the labor mix for impermeability testing . Earlier PMN SNUR economic analyses used the ECI for Private Industry White Collar Workers. 4 Beginning with th e report ,Economic Analysis of Expedited Significant New Use Rules for 2 5 Chemical Substances: EPA Docket OPPT - 2009- 0922 , we began to use the not- seasonally adjusted CIU2010000120000I for private industry Professional, and Related workers, instead of SA CIS2 010000W00000I for private industry white collar workers because BLS retired the “white - collar” series .Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C-1 January 2012

**and Recordkeeping R** **equirements** Section 2.1 of the main text of this report discusses costs of worker protection, hazard communication (haz - comm), and recordkeeping for SNURs . This appendix presents dollar costs and labor hours of these requirements, for one chemical at one site . Some requirements listed here may not be cited in the current rulemaking, but have been cited in past SNUR rulemakings. The haz - comm costs reflect the annual costs of updating the written program, labeling for chemical distribution and storage, creating and distributing material safety data sheets (MSDS), and employee training . The personal protective equipment (PPE) costs reflect the annualized costs of providing required equipment (i.e., gloves, goggles, clothing, or respirators), assessing dermal protection needs associated with the chemical, and performing required impermeability testing, and/or evaluating manufact urer’s information . Finally, the annual recordkeeping costs include labor, photocopying, and record storage costs. To estimate the costs of haz- comm, worker protection, and recordkeeping requirements, a number of assumptions were made, based on the original EPA analysis for generic SNUR provisions, Economic Analysis of Final Significant New Use Rule: General Provisions for New Chemical Followup ( EPA, 1989). In that report, EPA estimated that the number o f workers exposed to any one substance would range from 10 to 25, and that a worker potentially would be exposed to a substance for a minimum of 50 days per year to a maximum of 250 days per year . The current analysis uses the high ends of those two ranges . Thus, each site is assumed to have 25 chemically- exposed workers requiring training and/or protective equipment, with each of them assumed to be exposed for 250 days per year. Labor costs are derived from the United States Bureau of Labor Statistics sources as described in Appendix B . Material costs were primarily obtained from a national safety equipment supply house catalog (LSS, 1997) and are inflated as described in Appendix B. Costs of haz- comm, workplace protection, and recordkeeping are discussed in Sections C.1, C.2, and C.3, respectively . Table 4 and Table 6 in the main text summarize these costs by SNUR requirement. 

### Modifying the Hazard Communication Program As mentioned in Section 2.1, it is assumed that each facility has in place a haz- comm program consistent with that required by OSHA’s Hazard Communication standard (29 CFR 1910; November 25, 1983), so that costs attributable to the SNUR are costs of adding one chemical to the program . Much of the haz comm methodology and assumptions came from the EPA report, Economic Analysis of Final Si gnificant New Use Rules: General Provisions for New Chemical Followup ( EPA, 1989 ), which in turn relied partly on the 1983 OSHA study, Final Regulatory Impact and Regulatory Flexibility Analyses of the Hazard Communication Standard OSHA, 1983). Itwas assumed that the haz - comm costs would be incurred each year . For example, there would be worker turnover and need for refresher training, the MSDS would need revision due to changing information, placards would wear out (EPA, 1989 ). To the extent that some steps would not need repeating each year, costs could be lower than estimated here . The hazard communication costs summarized in Table 3 above are detailed here.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C-2 January 2012

**3.0.1 Updating the Written Program**  

### If the SNUR cites 40 CFR §721.72(a), then to avoid engaging in a Significant New Use, which would trigger other SNUR requirements, manufacturers must update their written haz - comm program to incorporate information about the chemical . The written part of the program includes data and information about hazardous chemicals present in the workplace, the hazards associated with such chemicals, procedures for employees who routinely work with or around such chemicals, pro cedures for non -routine tasks that may involve exposure (e.g., tank cleaning), and personal protective equipment requirements when working with or around such chemicals. While material safety data sheets may provide much of the information needed to update the written haz comm program, many employers may perform a more detailed assessment of exposure risks associated with the chemical and develop more site - specific procedures for workers potentially exposed to such chemicals. For purposes of the economic analysis, EPA assumes that each employer will engage the services of a professional industrial hygienist (IH), either in-house or on a consulting basis, for four hours to perform such an assessment . Loaded hourly rates for IH services were calculated based on Bureau of Labor Statistics data, as described in tables B - 1 and B -2. Costs for the written haz - comm program, in 2010 dollars, are as follows 25



### 4 hours Industrial Hygienist time × $ 51.24 per hour = $ 205 The estimates of IH hours to update the program come from a 1998 EPA report (EPA, 1998 ). **3.0.2 Labeling**  

### If the SNUR cites 40 CFR §721.72(b), then to avoid engaging in a Significant New Use, manufacturers must ensure that containers used to distribute the PMN substance in commerce are labeled with the necessary hazardous substance warnings and procedures . In addition, containers used in the workplace must bear similar labels or, alternatively, the employer must provide equivalent signage, operating procedures, or other written material to communicate hazard information to workers . The cost of providing such labeling was estimated in a 1989 EPA report (EPA, 1989 ) and has been updated here using more recent cost information. Standard formats are assumed to be used for creating labels or other signage, and the information required for the labels is assumed to be already available from the MSDS for the chemical (see below). **Chemicals Distributed in Commerce** . For chemicals distributed in commerce, the labeling process is assumed to require 0.5 hours of technical l abor time per chemical to compile label information . Itis assumed to require 480 labels per chemical . The assumption of 480 labels per chemical is from a 1989 EPA report ( EPA, 1989 ), and is based on the assumption that, on average, each chemical is shippe d twice monthly to 20 customers . This is consistent with roughly 10,000 kilograms of chemical per year shipped in 40 five - gallon containers per month ( EPA, 1989 ). 26

25 Figures presented here are rounded. 26 Data on PMN notices suggest that some PMN submitters expected to produce less than 10,000 kilograms per year of the SNUR chemicals, but many expected to produce much more. It is not known whether volumes listed in the PMNs were realized in practice. Production volumes of secondary suppliers affected by the SNUR are also unknown. Annual volumes significantly greater than 10,000 kg could lead to higher haz - comm costs than those estimated here.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C-3 January 2012



### Technical labor is fully loaded with fringe benefits and overhead, as described in Appendix B. Labeling materials costs were obtained from a national safety equipment supply house catalog (LSS, 1997) and were inflated as described in Appendix B . The resulting costs of labeling for chemicals distributed in commerce, per chemical substance at one s ite, are shown in Table C -1. **Table C -1**  **Annual Costs of Labeling for Distribution in Commerce [40 CFR §721.72(b)(2)] Cost Element**  **Unit Cost**

### Chemicals Used in the Workplace . Workplace labeling requirements are costed by assuming the facility purchases six large (14" × 10") signs, priced at $38.30 each in 1997 dollars (LSS, 1997; EPA, 1998 ) . Costs of these signs were inflated as described in Appendix B . These signs will be mounted in areas where the chemicals are used or formulated . For example, a placard might be posted at each of six vessels: a mixing tank, a reactor, two separators, and two storage vessels ( EPA, 1989 ). The labeling process is also assumed to require 0.5 hours of technical time to compile label information and 10 minutes of production worker time to post each placard . Technical labor costs include wages, fringe benefits, and overhead, as described in Appendix B. The resulting per chemical, per site costs of labeling for chemicals in the workplace are shown in Table C-2. **Table C -2**  **Annual Costs of Labeling for Use in Workplace [40 CFR §721.72(b)(1)] Cost Element**  **Unit Cost**  **(1997 Dollars) Inflation**

### If the SNUR cites 40 CFR §721.72(c), then to avoid engaging in a Significant New Use, each facility is required to create, post, and distribute material safety data sheets (MSDSs) . Based on estimates in OSHAEconomic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C-4 January 2012



### 1983, the 1989 EPA report ( EPA, 1989 ) has estimated that creation of an MSDS for a chemical substance requires 2.0 hours of technical labor time and 0.25 hours of clerical time . Further, EPA assumes that the manufacturer provides 20 copies of the MSDS to customers and retains 20 copies for use onsite, for a total of 40 copies ( EPA, 1989 ). The loaded hourly wage rates and the inflator used in estimating unit photocopy costs are derived in Appendix B . The resulting cost of MSDS preparation is shown in Table C 3 . **Table C -3**  **Annual Costs for Material Safety Data Sheets (MSDSs) [40 CFR §721.72(c)] Cost Element**  **Unit Cost**

### Employ**ee Training** The final required component of the haz - comm program is employee training, based on 40 CFR §721.72(d) . The 1989 EPA report, Economic Analysis of Final Significant New Use Rules: General Provisions for New Chemical Follow-up ( EPA, 1989 ), assumes that a training program currently is in place, but the existing program must be modif ied to add new information pertaining to the PMN substance . Subsequently, the training program must be expanded to include such material each time the training course is presented . Costs of modifying the program and presenting the modified program are mainly labor costs for the trainer and the trainees. Inserting the new information about the PMN substance into the training program and conducting the revised training is assumed to require 0.5 hours of the trainer’s time . An additional 0.25 hours per trainee is estimated to be required, and an average of 25 affected workers is assumed per facility ( EPA, 1989 ). If additional production workers needed to be trained, for example because they might come into contact with the chemical due to spills or leaks, training costs could be higher than estimated here ( EPA, 1989 ). Labor rates for training are based on the loaded rates derived in Appendix B for chemical technicians and chemical industry production workers . The total cost of the employee training requirement is shown in Table C -4.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C-5 January 2012

### Protection in the Workplace The following section estimates costs of assessing needs for dermal protection and evaluating protective gear for impermeability, as well as the costs of gloves, goggles, protective clothing, and respirators. **3.2.1 Dermal Protection Selection**  

### If the SNUR cites 40 CFR §721.63(a)(1), then to avoid engaging in a Significant New Use, the employer must ensure that each person who is likely to experience dermal expo sure to a PMN chemical, must be provided with and is required to wear personal protective equipment (e.g., gloves) that will prevent dermal exposure to the substance . The equipment must be selected and used in accordance with 29 CFR § § 1910.132 and 1910.1 33 (promulgated by the Occupational Safety and Health Administration, OSHA) . The selection and administration of this dermal protection is estimated to require 10 hours labor by an industrial hygienist, annually ( EPA, 1999 ). The wage rate of the hygienist was calculated as described in Appendix B . The cost calculations for the dermal protection selection requirement are given in Table C -5. This covers only costs of selecting the dermal protection needed, not costs of the items themselves . For costs of purchasing dermal protective items, see the sections below on costs of gloves, eyewear, and clothing. **Table C -5**  **Annual Costs fo r Dermal Protection Selection [40 CFR §721.63(a)(1)]**

ble B -1 ; cost elements and quantities, EPA, 1 999. **3.2.2 Impermeability Testing**  

### As part of the workplace protection requirements specified under 40 CFR §721.63(a)(3), to avoid engaging in a Significant New Use, the SNUR may require that employers demonstrate that each item of protective equipment provided (e.g., gloves) provides an impervious barrier, to protect employees from dermal exposure . Requirements outlined in §721.63(a)(3) are provided in two parts, §721 .63(a)(3)(i) and (ii) . The employer may use a combination of (i) testing and/or (ii) evaluating manufacturer specifications . The following discussion is based on the Economic Analysis of Expedited Significant New Use Rules for 168 Chemical Substances and Background Support Document for Economic Analysis of Significant NewEconomic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C-6 January 2012



### Use Rules ( EPA, 1998 ) and a ssumes that the manufacturer uses both testing and evaluation of manufacturer specifications . The analysis assumes that costs are incurred annually. The first step, described at 40 CFR §721.63(a)(3)(i), is to perform actual impermeability testing . To determine the costs of impermeability testing compliance, Best Manufacturing Company, a leading manufacturer and tester of chemical resistant articles, was consulted (Best, 1997). As described in EPA, 1998 , Best used one of two methodologies for impermeabi lity testing . In the first method, chemical samples were submitted to Best with a specific article to be tested for impermeability . This method was cheaper, costing $200 (1997 dollars) p er chemical, but the burden of finding an appropriate article of prote ction lay with the chemical manufacturer . In the second method, the chemical manufacturer simply submitted chemical samples to Best, who in turn determined the most appropriate product, even if a competitor manufactured the product . This method was more co stly at $800 (1997 dollars) per chemical . The second method of impermeability testing is favored in this analysis for several reasons . First, the burden of finding and submitting an article of protection is shifted from the chemical manufacturer to the testing company, who would have greater experience in Personal Protective Equipment (PPE) selection . Second, should the article submitted fail the impermeability test, other articles may have to be submitted until satisfactory test results are obtained . Furthermore, substances subject to SNURs may include new and/or rare chemicals, which may have undiscovered or unknown properties . This uncertainty may impede chemical manufacturers’ ability to effectively submit appropriate PPE articles for testing . Finally, the first method is essentially a pass - fail test . If an article passes the impermeability test, then it is acceptable . In the second method, several articles may be tested and compared, and, while one or more acceptable articles may result, the most imperme able article is always determined for the chemical . To obtain the best article rather than merely a satisfactory article of protection, the second method of testing is more appropriate . For these reasons, unit costs of $800 per chemical (1997 dollars) are assumed for impermeability testing . The cost of the impermeability testing is assumed to be driven by labor costs of the company performing the testing, thus test costs were inflated with an Employment Cost Index as described in Appendix B . The administration of this test would also require two hours of industrial hygienist labor ( EPA, 1999 ). The second step to compliance with the workplace protection requirements at §721.63 (a)(3)(ii) is the evaluation of specifications from the manufacturer or supplier of the protective equipment . This requirement helps ensure that the protective equipment will be impervious to the PMN chemical(s) . The evaluation of manufacturer specifications requires an estimated four hours of industrial hygienist labor. Annual costs of the impermeability testing requirements are presented in Table C -6.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C-7 January 2012

### If the SNUR cites 40 CFR §721.63(a)(2)(i), then gloves must be worn to avoid engaging in a Significant New Use . Gloves may also be acquired as a result of the dermal protection selection at §721.63 (a)( 1) . If standard, disposable medical - grade gloves are used, they are assumed to be worn and discarded by the worker following each day of exposure . Each site is assumed to have 25 workers, each of them exposed 250 days per year . This reflects the high - side assumptions in EPA, 1989 (page 25) for the number of workers and exposure days . Each pair was estimated to cost $0.43 in 1997 (LSS, 1997); the cost has been inflated as described in Appendix B . Total annual costs of providing disposable gloves are developed by applying the assumptions above regarding the number of workers exposed (25 per site) and frequency of replacement (one pair per worker per day of exposure H 250 days of exposure per year) . For some chemicals, heavy - duty gloves may be used . They are generally not disposed of daily, but are more expensive . The estimated costs of gloves purchased in compliance with SNUR Personal Protective Equipment requirements are presented below in Table C -7. The cost estimates for each chemical assume that the more expensive heavy- duty gloves are used in cases where the SNUR explicitly requires gloves. **Table C -7**  **Annual Cost of Gloves [40 CFR §721 .63(a)(2)(i)]**  **Cost Element Unit Cost**  **($1997 per pair)**  **Inflation**

**3.2.4 Eyewear**  

### If the SNUR cites 40 CFR §721.63(a)(2)(iii), then to avoid engaging in a Significant New Use, employer must provide eye protection . Eye protection may also be acquired as a result of the dermal protection selection at §721.63 (a)( 1) . Protective goggles are expected to be used at a rate of one set per worker and replaced every four months . Each site is assumed to have 25 workers, each of them exposed 250 days per year . The SNUR may not specify the exact type of eyewear required . OSHA guidelines in 29 CFR § 1910.133 (b)( 1), however, state that protective eye and face devices purchased after July 5, 1994 shall comply with ANSI Z87.1 -1989 . To determine the cost of goggles that meet thi s standard, EPA consulted with eyewear specialists at equipment supplier LSS . A standard pair of goggles that meets the ANSI Z87.1 - 1989 specification was priced at $4.05 per pair in 1997 (LSS, 1997; RIB, 1998) . A price estimate for a heavy - duty pair of goggles compliant with the ANSI standard is also included in Table C 8 . The cost estimates for each chemical assume that the more expensive heavy- duty goggles are used in cases where the SNUR explicitly requires goggles . Costs of protective eyewear were inflated as described in Appendix B and are presented in Table C -8 below. **Table C -8**  **Annual Cost of Protective Eyewear [40 CFR §721.63(a)(2)(iii)]**

### Costs for a standard coverall clothing set, estimated at $36.25 in 1997 (LSS, 1997), were inflated as described in Appendix B and are shown in Table C -9 below . Costs for full -body protective clothing are based on the coverall clothing set w ith a hood (LSS, 1997) as shown in Table C -9. If the SNUR cites 40 CFR §721.63(a)(2)(ii) or (iv), then to avoid engaging in a Significant New Use, emp loyers must provide protective clothing . Protective clothing may also be acquired as a result of the dermal protection selection at §721.63(a)(1) . Protective clothing, (a)(2)(iv), and full -body chemical resistant clothing, (a)(2)(ii), are assumed to last f our months . Each site is assumed to have 25 workers, each of them exposed 250 days per year. Table C -9 shows estimated costs, after inflating as described in Appendix B, for a standard coverall clothing set that cost $36.25 in 1997 (LSS, 1997) and for full -body protective clothing

### For some PMN chemicals, to avoid engaging in a Significant New Use, the SNUR requires either the use of respirators or compliance with a New Chemical Exposure Limit (NCEL) . Both requirements differ by chemical. 18 27

### For costing purposes, this analysis assumes that respirators are used . Earlier, PMN SNURs referenced specific paragraphs at 40 CFR §721.63 (a)(5) that identified fifteen types of NIOSH - approved respirator units . However, with rulemaking docket OPPT -2003 -0063 ( EPA, 2007b ), PMN SNURs began to describe respirator choices directly . Costs of the SNUR respirator choices were estimated based on the costs of the respirator in §721.63 (a)(5) that appeared to best match the SNUR descriptions.

27 EPA’s website at http://www.epa.go v/oppt/newchems/pubs/ncelmain.htm explains that in Consent Orders and subsequent SNURs, EPA can require respirators unless workplace air measurements show that air-borne concentrations of the chemical are below a New Chemical Exposure Limit established by EPA to protect health. NCEL provisions are modeled after Occupational Safety and Health Administration Permissible Exposure Limits (PELs), and also cover sampling and analytical methods, monitoring, respiratory protection, and recordkeeping.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C- 10 January 2012

Any significant differences between the specified respirator type at 40 CFR §721.63 (a)(5) and the SNUR text respirator type are noted in italics.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C- 11 January 2012



### Table C -11 gives average costs of various respirator types, both as originally estimated in 1997 and after applying inflation factors from Table B -3. Italso estimates costs per plant site for a chemical requiring respirators. The respirators specified in the SNURs are typically comprised of a respirator unit and any number of the following: special cartridges (such as high efficiency particulate filters, organic vapor cartridges, and paint, lacquer, and enamel filters), hoods or helmets, and filter caps . The costs for each site of providing respirators to chemically- exposed workers, shown in Table 4 of Chapter 2 of the report, are calculated based on the assumptions stated there, that (1) there are 25 chemically- exposed workers requiring protective equipment , (2) respirators are replaced once a year, and (3) cartridges (and cartridge filters and caps) are replaced at a rate of one pair (two cartridges) every five of the 250 days that workers are exposed, or 50 times per year . For example, for the respirator type described at 40 CFR §721.63(a)(5)(xv), the annual cost per worker in 1997 dollars would be as follows: $10.83 per respirator + ($8.94 per cartridge × 50 cartridges/year) = $457.83 per worker. The 1997 cost was adjusted for inflation as shown in Table C -11. Typically a SNUR describes more than one type of respirator, but only one type of respirator is needed to comply with the workplace protection requirements.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C- 12 January 2012

A “cartridge set” includes two cartridges and any filters or caps required . Assume s cartridge sets are replaced every five days (50 times during 250 exposure days) so that each worker requires one respirator unit and 50 cartridge sets per year. 3 Totals were estimated from unrounded unit costs and inflation factors, so results may differ from calculations using the rounded values shown in this table.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C- 13 January 2012



### Table C -12 shows how the average costs per NIOSH -ty pe respirator were calculated, based on prices of respirators listed in a 1997 catalog . To calculate the cost of respirators that meet the NIOSH criteria, the prices of all units in the supplier catalog (LSS, 1997) that meet each NIOSH criteria were averaged . Costs of additional items such as hoods, helmets, cartridges, and filter caps were also obtained . These are added to the cost of the basic respirator unit if they are required under the SNUR regulation and if the unit does not already include the item . For example, §721.63(a)(5)(x) requires a hood or helmet . One model in the catalog that satisfies the requirement already includes a hood, while another unit requires that a separate hood be purchased . The cost of the hood was added to the unit cost and the combined cost was then averaged with the model with integrated hood. Many respirator specifications also require cartridges . The costs of the cartridges listed in LSS (1997) were averaged for the corresponding requirements . In some instances, certain cartridges or filters require a secondary cartridge to function properly (e.g., some paint, lacquer and enamel filters required the organic vapors cartridges and filter retainer caps) . These additional items were priced and added to the cost for the basic cartridge before averages were taken. Some cartridge prices were unavailable from LSS (1997) . For instance, §721.63(a)(5)(ix) and (x) require a powered air-purifying respirator (PAPR) with a paint, lacquer and enamel cartridge . The only cartridges available for these models of respirators in LSS (1997) are HEPA cartridges . In these cases the costs of a paint, lacquer, and enamel cartridge are assumed to b e the same as for a HEPA cartridge. The 1997 purchase costs of the varying types of respiratory protective equipment are shown in Table C-12.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C- 14 January 2012

### Recordkeeping There are two main types of recordkeeping requirements for the substances listed in the current SNURs: those for companies submitting a SNUN, and those for all companies that manufacture, import or process SNUR-regulated substances, regardless of whether they have made a submission to EPA . **3.3.1 SNUN submitters**  

### Companies submitting a SNUN must keep records under 40 CFR §721.40 . Some EPA reports have assumed that SNUN recordkeeping hours would be 5 percent of SNUN submission hours, or about five to six hours. 28 

### Other EPA reports have estimated that electronic submission of SNUNs is expected to reduce the recordkeeping burden to approximately one hour (EPA, 2009a , p. 16 ) For this report, the SNUN recordkeeping hours were included in the SNUN submission hours (see Table 8 ) and the SNUN recordkeeping cost was not separately estimated. 29 **3.3.2 Al**  **l manufacturers, importers, and processors** 

### Whether or not they submit a SNUN, firms that manufacture, import, or process the SNUR substance must keep records based on 40 CFR §721.125(a) through (k), to document compliance with SNUR conditions for avoiding a Significant New Use . (For firms producing under the R&D exemption, R&D recordkeeping would be needed . R&D recordkeeping costs were not estimated for this report.) Recordkeeping requirements vary between PMN chemicals, reflecting differences in SNUR restrictions . For all chemicals in the current SNURs, manufacturers, importers, and processors must keep records on quantities supplied or purchased under 40 CFR §721.125(a), (b), and (c) . For chemicals with water discharge restrictions, companies must keep records concerning water discharge compliance, under §721.125(k) . For chemicals with other use restrictions, or for those few chemicals with workplace protection or hazard communication restrictions, companies must keep records under other 40CFR §721.125 paragraphs, to document compliance. All recordkeeping requirements essentially involve copying and filing relevant records, including those related to: manufacturing, importing, or processing volumes; shipment amounts and customer information; clothing impermeability determinations; the hazard communication program including labels and MSDS copies; compliance with other use restrictions; and/or compliance with disposal and release to water limitations . Records must be maintained for five years from the date of their creation. Costs for compliance with the recordkeeping requirements for substances subject to a SNUR are based on the approach in Economic Analysis of Final Significant New Use Rules: General Provisions for New Chemical Followup ( EPA, 1989 ) which in turn was based on Recordkeeping Costs for a Generic SNUR , prepared for EPA in 1988 by Kearney/Centaur (Kearney, 1988a) . These reports drew on recordkeeping 28 For example, OPPT’s Information Collection Request (ICR) for TSCA Section 5(a)(2) Significant New Use Rules for Existing Chemicals (Renewal), October 11, 2005, estimates SNUN recordkeeping costs at 5.67 hours (EPA 2005, page 12). 29 SNUN submission costs estimated in Table 8 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 no rmal 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 1 14 total hours for a PMN submission (page III - 10 of RIB 1994) included recordkeeping hours.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C- 18 January 2012



### costs estimated for the Comprehensive Assessment Information Rule, CAIR . Industry recordkeeping costs for CAIR compliance were estimated in reports Kearney prepared for EPA, including Estimated Cost of the Final Comprehensive Assessment Information Rule , June 1, 1988 (Kearney, 1988b, pages 63 to 65) . This report uses the basic Kearney (1988a and 1988b) estimates and assumptions to estimate recordkeeping costs for SNUR requirements. 30 

### Unlike Kearney (1988a), this report presents costs for each §721.125 recordkeeping requirement separately . This report also avoids minor rounding errors by calculating from unrounded data . However, the underlying methodology is identical to the Kearney 1988a/RIB 1989 reports, resulting in identical costs per chemical except for differences due to inflation and rounding . The paragraphs that follow de scribe estimates and assumptions used from Kearney (1988a and 1988b). **Cost per page**

**.** Recordkeeping costs are based on cost per page . Kearney (1988a) assumes that the ratios of labor hours to page count for each labor category, file drawer space to page cou nt, and cost of miscellaneous supplies such as folders and labels to page count, are the same as the per-page ratios estimated for EPA’s Comprehensive Assessment and Reporting Rule . The CAIR estimates are given in the 1988 report, Estimated Cost of the Fin al Comprehensive Assessment Information Rule , June 1, 1988, page 65 (Kearney, 1988b) . Table C -13 summarizes estimates from Kearney 1988a and the CAIR report (Kearney, 1988b) . Italso shows the derivation of costs from these estimates , after inflation . The method is as follows:

 

### Technical labor was estimated at 1 hour for 750 pages in the CAIR report (Kearney, 1988b, page 65), or .00133 hours per page . The analysis estimates a cost per hour and per page using fully loaded labor rates from Table B -1.

 

### Clerical labor was estimated at 10 hours for 750 pages in the CAIR report (Kearney, 1988b, page 65), or .01333 hours per page . The analysis estimates a cost per hour and per page using fully loaded labor rates from Table B -1.

 

### The photocopying cost from Kearney 1988a ($0.05 per page) was inflated using an inflation factor from Table B -3.

 

### File space for CAIR was estimated at 1⁄4 of a four- drawer file cabinet for 750 pages (Kearney, 1988b, page 65) or 0.000333 of a cabinet per page . A standard, four- drawer, full - suspension file cabinet was priced from a national office products supplier at $195 in 1997 (BT O ffice Products, 1997; Item #LGM -202401; EPA, 1998 ). This results in $0.065 per page cost for file space, before inflation ($195 × 0.25 file cabinet/750 pages) . The cost per page was inflated using an inflation factor from Table B -3.

 

### Miscellaneous materials costs were estimated at $10.00 for 750 pages in the CAIR report (Kearney, 1988b, page 65), or $0.0133/page before inflation . This cost per page was inflated using an inflation factor from Table B -3 

### .

30 This report follows the method in Economic Analysis of Expedited Significant New Use Rules for 65 Chemical Substances (EPA Docket OPPT - 2003 - 0063) , (EPA, 2007b), which used the Kearney data to calculate the cost breakdow n by recordkeeping requirement.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 C- 19 January 2012

The CAIR per-page costs were then used to estimate SNUR recordkeeping per-page costs in Kearney 1988a . This clarifies the method by which the original CAIR per-page costs and hours were calculated . It also adjusts costs for inflation using labor rates from Table B -1 and inflation factors from Table B -3 . 

### Pages per chemical at one **site.** In order to estimate recordkeeping costs, the analysis multiplies the costs per page for each recordkeeping element estimated in Table C -13 by the number of pages required for each SNUR recordkeeping requirement at 40 CFR §721.125 as estimated by Kearney (1998a) . The Kearney data was used by EPA in its original expedited- SNUR economic analysis ( EPA, 1989 ). For example, maintaining MSDS copies as required at §721.125(h) would require 5 pages . The following estimates from Kearney (1988a) are also used:

 

### Manufacture and import volume, and sales and transfer data require 485 pages of records per year . This reflects 40 invoices per month (see haz - comm Section C.1 above), 480 for sales/transfer and 5 for manufacturer/import (Kearney, 1988a, p.11). Disposal compliance records, if required, cover items such as waste production, shipping manifests, permits, and transfer receipts . The 600 disposal compliance pages assume 50 pages per month (Kearney, 1988a, p.11). (This report uses slightly different terminology from EPA, 1989 : “Protective clothing” instead of “protective gloves,” “haz - comm” instead of “employee information and training.” Recordkeeping for “impermeability determination” was not separately costed out in EPA, 1989 . This report assumes it is included under “protective clothing” recordkeeping.) **Cost per chemical**

**.** Table C -14 shows annual recordkeeping activities at one site for one SNUR chemical, by CFR requirement . If all recordkeeping requirements at 40 CFR §721.125 applied to a single chemical, there would be costs for 2.3 hours of technical time, 23 hours of clerical time, 1,715 photocopies, approximately one -half of a four- drawer file cabinet, and other miscellaneous materials such as folders .

## C **osts of**  **T esting**  EPA recognizes that TSCA Section 5 does not require developing any p articular test data before submission of a Significant New Use Notice . Persons are required only to submit test data in their possession or control and to describe any other data known to or reasonably ascertainable by them . (Upon review of a SNUN, the Agency has the authority to require appropriate testing, but that is a cost of regulatory follow -up , not of the SNUN submission itself.) For informational purposes, the SNURs describe tests recommended by EPA to provide sufficient information to evaluate the chemical substance . However, as was explained in the discussion of SNUNs earlier in this report , it appears that firms rarely elect to do these recommended tests to support a SNUN, and especially not the higher- cost tests . For informational purposes, this appendix presents estimated costs for testing often recommended for chemicals that have been the subject of PMNs and are subject to Significant New Use Rules (SNURs). 

### Testing Guidelines In the SNURs, EPA identifies a set of tests for each PMN chemical that can be used by firms making Significant New Use Notice or other submissions to EPA to characterize risks of the chemical . The tests are recommended in the SNUR, not mandatory . They are identified by guideline numbers which can be used to look up published test protocols . Table D -1 lists test guidelines cited in the current and recent SNUR rulemakings, and their associated costs, Table D -2 presents certain assumptions used in the analysis, and Table D -3 presents Persistent Bioaccumulative Toxic (PBT) tiered testing requirements . The types of guidelines are described below. **4.0.1 OPPTS Harmonized Test Guidelines**  

### Most SNUR tests are identified by their OPPTS number from the series of OPPTS Harmonized Test Guidelines and OPPTS harmonized public drafts not yet promulgated as OPPTS guidelines . These guidelines blended testing guidance from OPPT (published in the Code of Federal Regulations), EPA's Office of Pesticide Programs, the Organization for Economi c Cooperation and Development (OECD), and other sources . The harmonized guidelines fall into several categories, including the following:

 Series 835 -- Fate, Transport and Transformation Test Guidelines  Series 850 -- Ecological Effects Test Guidelines  Series 870 -- Health Effects Test Guidelines They are available electronically on EPA’s website (EPA, 2006 ). Cross -references for health effects guidelines are listed at 63 FR 41847, August 5, 1998. **4.0.2 C**  **ode of Federal Regulations** 

### SNUR tests may also come from the Code of Federal Regulations (CFR), identified for example as “40 CFR 799.9370” or just “799.9370.” In addition, in costing out test guidelines, this report sometimes uses costs for a CFR guideline when costs have not been developed for the equivalent OPPTS har monized guideline . 40 CFR parts 795 through 798 include pre -harmonization test guidelines, typically updated before 1990 . 40 CFR part 799 includes more recent TSCA test guidelines, based on harmonized test guidelines. (63 FR 41845, August 5, 1998).Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 D-2 January 2012

**4.0.3 OECD**  

### A few SNUR tests are identified by their OECD number . The OECD guidelines may have OPPTS equivalents . For example, OECD 407 28 -Day Oral Toxicity in Rats is essentially equivalent to OPPTS 870.3050. **4.0.4 OECD**  **’ s Guidance Manual for the Testing of Manufactured Nan**  **omaterials** 

### For some nanomaterials SNUR tests may refer to OECD’s Guidance Manual for the Testing of Manufactured Nanomaterials . Because of the newness of nanomaterial testing test s may not have protocol numbers, but rather refer to the guidelines described in the manual . **4.0.5 PBT Category**  

### For some chemicals, the SNUR cites tiered testing according to a testing strategy published in the Federal Register (FR), Category for Persistent, Bio accumulative, and Toxic New Chemical Substances, November 4, 1999 (64 FR 60194), which in turn refers to a number of tests by OPPTS or OECD guideline number. **4.0.6 ASTM, NTIS, and**  **O ther**  **Sources** 

### Test guidelines may also come from the American Society for Testing and Materials (for example, ASTM D2035 - 80 Modified Coagulation- flocculation Jar Test of Water) (www.astm.org) or other sources . The guideline for a neurotoxicity functional observational battery, NTIS PB 91 - 154617, is available from the National Technical Information Service (www.ntis.gov).Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 D-3 January 2012

These activities would raise testing cost substantially. 1 The recommended testing for some PMN chemicals may include a glove permeation test following ASTM F739 and F1194 - 99 guidelines . ASTM F1194 -99 is a standard guide for documenting the results of chemical permeation tests (see www.astm.org) . The additional costs of following ASTM F1194 - 99 (average of gases and liquids) were not estimated for this report. 2 Costs for field testing will be site - specific, with a wide range of actual costs . A report f rom EPA's Office of P esticide Programs estimated an average test c ost of $600,00 0 for guideline 850.1950, for simulated or actual field testing for aquatic organisms (EPA, 2008a , Appendix C). 3 Performing the test on species other than rats may change the test costs . For example, testing on rabbits is likely to increase costs. 4 F ate, transport and transformation, ecological effects, and health effects testing may be required for nanomaterials, however nano - specific costs for these tests were not estimated for this report . 5 While the Agency expects that analytical methodology validation costs may be more expensive for nanomaterials than for traditional chemicals, EPA was unable to gather any information on nanomaterial -specific analytical methodology valid ation and therefore uses the traditional chemical costs as a proxy. 6 The test cost is an average of the test costs for three methods: EELS, XPS (ESCA), and Auger electron spectroscopy. **Source:** EPA OPPTS Economic and Policy Analysis Branch cost estimates . Many costs were estimated in the 1990s or earlier . All have been inflated (see Table B -1 and Table B 3 for inflation index) . Dollar costs include $ 4,054 or $ 9,854 for analytical method validation; where applicable (see text) . Species and route or method may be specified in SNURs or may be unspecified but assumed in this table for costing purposes.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 D- 11 January 2012



### Test Costs by

**Guideline** Table D -1 gives dollar cost for each test, based on assumptions and adjustments discussed below . This section describes the development of individual test costs. EPA’s Office of Pollution Prevention and Toxics, Economic and Analysis Branch, regularly develops cost estimates of test guidelines to support TSCA rule development . Estimates are based on assumptions about species, route of administration, study duration, and other aspects of methodology . Costs are calculated based on costs of labor, materials, and equipment needed to p erform testing, with overhead and fee . Many of the test costs were developed in the 1990s . Test costs have been inflated using Employment Cost Index inflators from the Bureau of Labor Statistics (see Appendix B) . However, generally they have not been updated to reflect subsequent changes in laboratory technologies. Testing laboratories perform analytical method validation to ensure that proper dose concentrations are used in toxicity studies (EPA , 2005a , p. 3 -9). This analysis assumes that for health effects tests (e.g. 870 series guidelines), tests of up to 90 days in duration have method validation costs of $3,500, and longerterm tests have validation costs of $8,500 in 2004 dollars . Using the inflation rates found in Appendix B, validation costs are $ 4,054 and $ 9,854 in 20 10 dollars . For simplicity, the method validation cost for ecological effects tests (e.g. 850 series guidelines) was assumed to be $ 4,054 for each test. In addition, this analyses assumes that analytical method validation costs are the same for both nanomaterials and traditional chemcials. In cases where costs have not been estimated for the specified guideline, EPA uses the cost from an approximately equivalent guideline (listed in Table D -1 and Table D -3 in parentheses) . Many of these equivalents are listed in the Federal Register at 63 FR 41847, August 5, 1998 . In some cases the test protocol itself states that it is essentially equivalent to another test upon which it was based . Sometimes judgment was needed to select the closest equivalent(s) **.** In some cases, EPA has not costed out the test for the species, route, duration, and/or other method listed in the SNUR, or the SNUR specifies a gui deline but does not specify these details . In such cases, EPA has made the adjustments described below . The adjustments were selected based on discussions with EPA scientists and on SNUR language, published test guidelines, assumptions underlying the cost estimates in EPAB's test cost database, EPA review and Consent Order history for specific PMNs, or other sources. **4.1.1 Default Parameters**  

### Costs for many of the guidelines have been estimated for different combinations of species, route, length of study and other aspects of methodology, but in some cases the SNUR may not specify all of these variables . Where this occurs, EPA has used certain default parameters, listed in Table D -2.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 D- 12 January 2012

### A SNUR may recommend tiered testing . In such cases, costs are lower if only the first-tier tests are performed, and higher if all tests listed for the chemical are performed . Testing is “tiered” if later tests are contingent on the results of earlier tests, and/or if some tests are contingent on the firm reaching a certain chemical volume or time limit . Some tiers are explicit in the SNUR text; others result because the SNUR references the tiered PBT Category testing described at 64 FR 60194 . **4.1.3 Test Cost A** **ssumptions and Comments**

This guideline has been previously costed by EPA for four separate algal species ( Navicula pelliculosa, Skeletonema costatum, Anabaena flos - aquae, and Selenastrum capricornutum ). If a SNUR does not specify the algal species to be used, the average costs of the four algal species tests are used.

 

### For OPPTS test guideline 835.3100 (Aerobic Aquatic Biodegradation) , a SNUR may call for an additional analytical methodology to identify the isononyl phenol degradation product, which may be a substantial add- on to the basic cost . Table D -1 gives costs for 835.3100 but not for the extended test .  

### A SNUR may recommend a “modified” version of ASTM test guideline D2035 - 80 ( CoagulationFlocculation Jar Test of Water) . Table D -1 gives costs for D2035 - 80 but not for the additional analytical methodology .  

### For test guideline OECD 422 ( Combined Repeated Dose Oral Toxicity with Reproductive/ Developmental Toxicity Screening), a SNUR may recommend extended histopathology . Although the OECD 422 protocol does include histopathology, it is possible that extending the histopathology would increase the cost beyond that shown in Table D -1.

 

### A SNUR may recommend two variations of test guideline OECD 218 (Chironomid Sediment Toxicity), one using the acute portion of the sediment and the other using the chronic portion . Costs were not determined for these two variants . The cost of the test performed on midge under flow through conditions was used for both.Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 D- 13 January 2012  

### A SNUR may recommend “a fish acute toxicity test, freshwater and marine (OPPTS 850.1075 test guideline)” . “Freshwater and marine” refers to the name of the test, not the number of species required by EPA . The cost estimates assume only one species is used. **4.1.4 Persistent Bioaccumulative Toxic (PBT) tiered testing**  

### A SNUR may cite tiered testing for Persistent Bioaccumulative Toxic chemical substances (PBTs) according to the testing strategy in EPA’s New Chemicals Program PBT Category document, published in the Federal Register notice, Category for Persistent, Bioacc umulative, and Toxic New Chemical Substances, November 4, 1999, at 64 FR 60194 . In 64 FR 60194, there are three tiers of testing . The results of Tier 1 determine whether Tier 2 testing is needed and the results of Tier 2 testing determine whether Tier 3 testing is needed . Table D -3 lists the tests in the PBT category document . These tests are also listed in Tab le D -1. To obtain a cost estimate for SNURs that cite PBT Category testing (64 FR 60194), costs of individual tests from 64 FR 60194 would have to be added up as appropriate, depending on the specific SNUR language . The test list would also need to be adjusted to avoid double counting tests listed in the SNUR both explicitly by guideline number, and implicitly due to their inclusion in PBT Category tiers. Other assumption s related to PBT testing are described below:

 

### The PBT category tests at 64 FR 60194 specify rainbow trout as the species for the chronic fish toxicity test, 850.1400 . For SNURs that recommend PBT Category testing, 850.1400 costs would be based on using rainbow trout . If 850.1400 is recommended without PBT testing, costs would be based on using fathead minnows.

 

### For PBT Tier 1 ready biodegradability tests, firms may either choose among six methods in test guideline 835.3110 or follow test guideline 835.3120 . The cost of 835.3110 is calculated as the average cost of its six possible methods . The cost estimates assume an equal chance of using either 835.3110 or 835.3120 .Economic Analysis of Expedited SNURs, Docket OPPT - 2011 - 0942 D- 14 January 2012

This table uses costs for 850.1300 and 850.1400 since they were costed out more recently by EPA. 

### T **esting Costs by**

**Chemical** Test costs attributable to a SNUN are likely to be much lower than the costs that would be implied by adding up costs of all of the testing recommended in the SNUR for that chemical, and usually are zero. 31 

### See the main text of this report for a discussion of testing.
