### 1.0 Introduction This appendix analy

zes the expected impact of the final TSCA Section 5 Premanufacture and Significant New Use Notification Electronic Reporting Rule [RI N 2070
- AJ41] on the paperwork burden associated with the following existing approved IC R s:

 Pre
- Manufacture Review Reporting and Exemption Requirements for New Chemical Substances and Significant New Use Reporting Requirements for Chemical Substances (OMB Control No. 2070

- 0012)

 TSCA Section 5(a)(2) Significant New Use Rules for Existing Chem icals (OMB Control No. 2070

- 0038). The two ICRs have some similar information collection components; this appendix describes certain baseline adjustments made for consistency between burden estimates. In addition, this appendix also describes the program change

- related burden increases and reductions that are the expected outcome of implementing the e - PMN rule. 1.1 Terminology 1.1.1 Company- level Burden Company
- level burden includes those activities that facilitate submission of an e - PMN : CDX registration, CDX electronic signature (i.e., authentication of identity and verification of authorization), setting up a Pay .gov account, and rule familiarization. All activities performed at the company- level occur only once during the first year that an activity is undertaken. Rule familiarization, for example, will be incurred b y all companies during the first year following promulgation of the e - PMN rule, regardless of whether the e - PMN is submitted via paper, optical disc, or CDX. In addition, companies that submit section 5 notices for the first time in subsequent years will incur rule familiarization burden the first year they submit a section 5 notice. Those companies that submit e - PMN s again in subsequent years do not incur a subsequent rule familiarization burden. All other company- level activities, while they are incurred onl y once, will be incurred in the year in which the company adopts electronic reporting via CDX. 1. 1.2 Form - level Burden Form
- level burden includes form completion, recordkeeping, and postage. As a result of the e - PMN rule, submitters will experience a reduction in form

- level burden due to the efficiencies and reduced time associated with using the new e - PMN software to fill out section 5 notices and using CDX to submit these notices. All form

- level burden savings are expected to be realized each time a section 5 notice is submitted. Recordkeeping and postage savings will be realized in years when electronic reporting via CDX is used. However, b ecause all notices must be generated using the new e - PMN software beginning in the first ye ar following rule promulgation, form completion burden saving will be realiz ed b y all submitters immediately.

### 1.2 Assumptions 1.2.1 Respondents This information collection affects companies that manufacture, process or import chemical substances. These companies are typically found in NAICS major groups 325 (Chemical Manufacture) and 324 (Petroleum and Coal Products). EPA estimates that there are 305 respondent companies that will submit TSCA section 5 notices to EPA. The Agency estimates 295 respondents under the New Chemicals Program and a n additional 10 respondents under the Existing Chemicals Program. Burden and cost calculations are based on the assumption that EPA will receive an annual average of 2,135 TSCA section 5 notices under the New Chemicals program and 10 TSCA significant new use notices (SNUNs) under Existing Chemicals program. The estimated number of notices that will be submitted under the New Chemicals program is derived by averaging the number of notices received in years 2003 through 2007 for each of the submission ty pes listed in the paragraph above, adjusting these averages b y 15 percent to reflect only valid submissions and then summing these averages (See Table 1). Table 1

### 1.2.2 Number and Types of TSCA Section 5 Notic es Submitted Under New Chemicals Program The number of notices that EPA expects to be submitted each year is typically estimated by averaging the number of each typ e of submission received over the past three ye ars according to data provided in the OPPT New Chemicals Annual Report (EPA, 2006) and adjusting it b y 15 percent to reflect only

valid submissions. However, for this ICR, the numbers of notice s were

### averaged for the past five years (2003 through 2007) to provide a longer term picture of section 5

activity as part of the economic anal ys is for the e - PMN rule ( EPA, 200 9 .) This change in method of determining the average annual number of responses has resulted in baseline burden adjustments, as described in section 2 of this appendix , for which EPA has accounted prior to anal yz ing the impact of the final rule on the overall reporting and recordkeeping burden Prior to the 1995 amendments to the PMN rule, 70 to 80 percent of all TSCA section 5 notices were full PMN submissions. From 1995 through 2003, the increase in exemptions did not significantl y change this distribution. However, since 2003, full PMN submissions accounted on average for approx imately 60 percent of all TSCA section 5 submissions. EPA expects few persons to submit significant new use notices (SNUNs). The number of SNUNs submitted is a function of the number of chemicals regulated under Significant New Use Rules (SNURs), which are relatively few. Based on the average number of SNUNs received annually during the last five years, the Agency expects to receive approximately eight SNUNs annually
. The amendments also placed stricter control on bona fide notices, which are intended to establish bona fide intent on the part of the submitter to manufacture or import a chemical substance. These controls were established in response to the steadily increasing number of bona fide notices submitted to EPA. The amendments have caused a si gnificant reduction in bona fide submissions. Historical EPA data suggests that EPA should expect 116 bona fide notices to be submitted annually
. On average, EPA expects LVE and LoREX exemptions to account for approximately 419 notices annuall y. TMEs are expected to average eight applications per year, or less than one percent of all TSCA section 5 notices. NOCs are expected to account for 443 notices annuall y, while correction requests are expected to account for nine notices annually, or less than one percent of all TSCA section 5 notices (EPA, 2006, and EPA, 200 9 ). The various exemptions available to submitters since the 1995 PMN amendments have reduced significantly

the need for consent order development and post

- notice data review. Historical EPA data indicate that such consent orders and post

- notice data reviews will account for roughl y two percent of the total TSCA section 5 notices. Based on historical data, EPA estimates 28 cases will be subject to TSCA section 5(e) consent order restrictions burden, with 12 cases requiring test data, and 16 non

- testing TSCA section 5(e) cases. Testing is usually contracted out to a laboratory , thus the burden associated with testing requirements represents the time that personnel from the submitting firm will spend overseeing the testing, assumed to be 25 percent of the lab burden.

1.2.3 Number and Types of Significant New Use Notices Submitted Under Existing Chemicals Program As explained in EPA ICR No. 1188.0 9 (OMB Control No. 2070

- 0038) , EPA estimates that it will receive 10 SNUNs per ye ar under TSCA Section 5(a)(2) during the three

- ye ar period covered b y this ICR (see Table 2).

2.0 Impacts of e - PMN Final Rule on New Chemicals Program Burdens (OMB Control No. 2070 - 0012) 2.1 Adjustments to the Baseline Number of Response s As mentioned in section 1.2.2 of this appendix, EPA utilized a somewhat different approach to project the number of new chemicals respondents and responses for this burden anal ys is than was used for the same projection in the ICR currentl y approved under OMB Control No. 2070

- 0012. For this anal ys is, EPA considered the average number of responses submitted annually

over a 5
- year period and adjusted the annual average b y 15 percent to count only valid submissions. Previously , EPA had traditionally based its projections on the number of responses submitted in each of the previous 3 years. This change in calculation led EPA to estimate that 203 fewer net responses would be submitted annually across all ty

pes of activities covered under this ICR. The reduction in the number of baseline responses will impact the baseline annual burden estimate of 148,803 hours (143,450 reporting hours + 4,633 recordkeeping hours) currently approved under EPA ICR No. 0574.13. 2.1.1 Impact of Adjusted Baseline Number of Responses on Reporting Burden With a projected 203 fewer annual responses, EPA estimates a net reporting burden decrease of 14 ,289 hours (an adjustment) over the current reporting burden baseline projections for each activity

in the ICR currently

approved under OMB Control No. 2070

- 0012. A break out of the projected change in number of responses b y ty pe of submission, as well as the resulting change in reporting burden, is provided in Table 3.

2.1.2 Impact of Adjusted Baseline Number of Responses on Re cordkeep ing Burden Similarly, EPA estimates a net recordkeeping burden decrease of 345 hours (an adjustment) over the current recordkeeping burden baseline projections for each activity in the

### ICR currentl y approved under OMB Control No. 2070

- 0012 as a r esult of a projected 203 fewer

annual responses. A break out of the projected change in number of responses by type of submission, as well as the resulting change in recordkeeping burden, is provided in Table 4.

### 2.1.3 Summary Burden Impact of Baseline Response Adjustments The overall impact of the adjusted baseline number of responses is a net reduction of 14,63 4 annual burden hours. With these adjustments, the baseline reporting and recordkeeping burden is reduced to 133,449 hours ( 129 , 161 hours and the baseline recordkeeping burden is reduced to 4,288 hours).Table 5 Total New Chemicals Baseline Burden Adju stments Baseline Reporting Burden Adjustments

### 2. 2 Reporting Burden Program Changes Upon implementation of the final rule, the average annual new chemicals reporting burden is estimated to be approximately 114,670 hours. As discus sed in section 1 of this appendix, respondents will incur new, company- level reporting burdens while realizing form
level reporting burden savings. Company
- level reporting burden includes those activities that facilitate submission of an e - PMN : CDX registration, CDX electronic signature (i.e., authentication of identity and verification of authorization), setting up a Pay .gov account, and rule familiarization. Form
- level burden includes completion and submission of TSCA section 5 notices.2.2.1 New Company- Level Reporting Burden s EPA estimates that the e - PMN rule will impose an average program change increase o f 353 annual burden hours on respondents and is associated with the time required to complete company- level paperwork activities related to the final e - PMN rule requirements, i.e., CDX Registration, CDX e lectronic s ignature, E

- Pay ment (Pay .gov ID), and Rul e Familiarization. These activities and related burdens are explained in full in the supporting statement for EPA ICR No. 2327.07 (OMB Control No. 2070

- 0173). They are also included in the burden analysis presented in Tables 7 through 9. As indicated in Table 7 , company- level burdens are higher in the first year due to initial rule familiarization burdens which are not incurred in subsequent ye ars. 2.2.2 Reductions in Form- Level Reporting Burden for New Chemicals Submissions The baseline reporting burden hours for each type of notice were estimated in Pre

Manufacture Review Reporting and Exemption Requirements for New Chemical Substances and Significant New Use Reporting Requirements for Chemical Substances (EPA ICR No. 0574.13; OMB Control No. 2070

- 0012 ). However, respondent adoption of electronic preparation and submission under the e - PMN rule will affect the existing reporting burden hour estimates for each type of covered notice 1 

### . The adoption of electronic preparation and submission through CDX using the e

- PMN software to prepare and submit TSCA section 5 notices will bring about burden savings b y creating administrative efficiencies and time savings. The reporting burden savings relative to specific notice types are indicated in Table 6. The net impacts of these

1 EPA is not accepting the electronic submission of certain types of documents and notices that are customarily p art of the new chemicals program. In those cases, there are no program change reductions to form

- level reporting or recordkeeping burden.

### changes, coupled with the new rule related burdens described in section 2.2.1 of this appendix,

are demonstrated in Tables 7 through 9. Table 6

### Because the final e - PMN rule phases

- in the use of CDX over the three

- ye ar period, the number of companies and forms using CDX will vary across the phase

- in period. Therefore, burden hours are presented separatel y for each ye ar of the phase

- in period. Prior to the e - PMN rule, only form
- level burden was estimated for section 5 notices. Due to new activities th at will occur at the company- level once electronic reporting via CDX is available, burden is broken out at the company and form level in the rule

- related ICR. Tables 7, 8 and 9 present the respondent reporting burden associated with this information coll ection during the first 3 years of rule implementation. The form

- level during each of these ye ars is estimated to total 114,317 hours. This burden estimate is calculated b y multiplying the hours of reporting burden b y the number of each type of notice that EPA expects to receive and summing across the notice typ es. Note that burden is adjusted to reflect the savings associated with the e - PMN rule in each year of the phase

- in period , and also reflects adjustments to the baseline number of TSCA section 5 notices expected to be submitted to the new chemicals program
. Because all notices must be generated using the new e - PMN software beginning in the first ye ar following rule promulgation, however, form completion burden saving will be realized by

all submitters immediately
. After accounting for the baseline adjustments described in section 2.1.1 of this appendix, the estimated 114,317 annual hours of form

- level reporting burden reflects a 14 , 844 hour net program change reduction.Table 7 Revised New Chemicals Program Reporting Burden Under the e - PM N Rule, Year 1

### 2. 3 New Chemic als Recordkeeping Burden Program Changes Respondents will not incur any company- level recordkeeping burdens
. Rather, they will realize f orm - level recordkeeping burden savings related to electronicall y s ubmitted TSCA section 5 notices. However, while respondents will realize immediate reporting burden savings since all respondents will be required to use the e

- PMN software to prepare their submissions, not all respondents will realize immediate recordkeeping burden savings. As described in

### section 1.1.2 of this appendix, recordkeeping and postage savings will be realized in years when

electronic reporting via CDX is used . Reductions in recordkeeping burden are contingent upon adoption of electronic submission via CDX. Once a respondent electronically submits information in an initial TSCA section 5 submission, the burden for maintaining or updating these records is minimal. EPA expects that 33 percent of respondents to submit TSCA section 5 notices electronically

via CDX in the first year, 67 percent wi ll do so by the second year, and 100 percent will do so by the third year (when all respondents are required to submit electronicall y)
. Thus, the average annual new chemicals recordkeeping burden over the first 3 years of the rule is approximately 3 ,339 h ours (and 2,863 hours annually each ye ar thereafter). 2.3.1 Reductions in Form- Level Re cordkeep ing Burden for New Chemicals Submissions The estimated 2 hours for each SNUN recordkeeping reflects is an aggregate annualized recordkeeping burden is an as sumption based on the recordkeeping burden associated with essential technical requirements, such as records that demonstrate that the first commercial batch of chemical manufactured for commercial purposes under the exemption met certain eligibility criteria. EPA assumes that recordkeeping burden will be reduced b y half due to the efficiencies in electronicall y creating and storing those TSCA section 5 notices and supporting documents that are covered b y the final rule. For most TSCA section 5 notices cov ered by the rule , baseline recordkeeping burden is estimated to be two hours. The recordkeeping burden savings relative to specific notice ty pes are indicated in Table 10. For these notices, one technical and one clerical staff member will each save 3 0 minutes on recordkeeping. For section 5(e) test notices, baseline recordkeeping burden is estimated to be 35 hours because of the need to copy and file relevant records. This includes records related to: manufacturing, importing, or processing volumes; shipment amounts and customer information; labels (documentation of labeling procedures and copies of labels); MSDS; and compliance with any additional restrictions on use, disposal, and discharge limitations. Therefore, for section 5(e) test notices, EPA estimates that one technical and one clerical staff member will each save 8.8 hours on recordkeeping. For Notices of Commencement (NOC), baseline recordkeeping burden is estimated to be 15 minutes. Therefore, for NOCs, one technical and one clerical staff member will each save four minutes on recordkeeping. As shown in Tables 11 , 12 , and 13 , the total respondent recordkeeping burden associated with this information collection is estimated to equal 3,81 4 hours in the first year following the effective date of the e

- PMN rule, 3,34 1 hours in the second ye ar, and 2,86 3 hours in the third ye ar following the eff

e ctive date of the final rule. This burden estimate is calculated b y multiplying the estimated recordkeeping burden associated with each ty pe of submiss ion (as estimated in EPA 1994) by the estimated number of submissions for each notice and then summing across notice types. Note that recordkeeping burden is adjusted by the savings associated with electronic reporting via CDX in each ye ar of the phase

- in period , and also reflects adjustments to the baseline number of TSCA section 5 notices expected to be submitted to the new chemicals programTable 10

- 0012) and the Economic Analysis for the final e - PMN rule. 

### O nce a respondent submits information in an initial TSCA section 5 submission, the burden for maintaining or updating these records is minimal. The Agency had assumed an aggregate annualized recordkeeping burden of two hours for each PMN, SNUN, MCAN, or ex emption submission, or biotech submission. This was based on the recordkeeping burden associated with essential technical requirements, such as records that demonstrate that the first commercial batch of chemical manufactured for commercial purposes under the exemption met certain eligibility

criteria. The recordkeeping burden for 5(e) testing and non

- testing 5(e) burden were 35 and 25 hours, respectively (EPA, 1994). The Agency expects that promulgation of the e - PMN rule and the submission of fewer TSCA section 5 notices will reduce the recordkeeping burden from the current total of 4, 633 hours to 2,863 hours by the third ye ar . The average recordkeeping burden of the first 3 years of the rule is 3 ,339 annual hours
. A fter accounting for the baseline recordkeeping burden adjustments described in section 2.1.2 of this appendix, this figure reflects an average annual 949 hour net program change reduction over the first 3 years of the rule (474 hours in the first year, 947 hours in the second year, and 1 , 425 in the third year and all subsequent years).13 Table 11 Revised New Chemicals Program Respondent Recordkeeping Burden Under the e - PMN Rule, Year 1

### 3.0 Impacts of e - PMN Final Rule on Existing Chemicals Program Burdens (OMB Control No. 2070 - 0038) 3.1 Adjustments to the Baseline Reporting and Recordkeeping E stimates for Existing Chemical SNUNs The baseline reporting and recordkeeping burden for the currently approved ICR entitled TSCA Section 5(a)(2) Significant New Use Rules for Existing Chemicals (EPA ICR No. 1188.0 9; OMB Control No. 2070

- 0038) is 1,423 annual hours. Of the 1,423 annual burden hours approved under that ICR, EPA estimated that the annual reporting and recordkeeping burden related to the submission of existing chemical SNUNs is 1,189 hours (about 1 , 132 reporting hours and 5 7 recordkeeping hours). In calculating the SNUN

- related burden subtotal for that I CR, EPA estimated that the SNUN
- related reporting burden ranges between 94.25 and 113.25 hours per response, as shown in Table 16. In keeping with the conservative assumptions already emplo yed, EPA used the high end of the range of reporting burden hours (i.e., 113.25 hours) in subsequent cost and overall

### annual burden hour calculations. EPA then assumed that SNUN

- related recordkeeping requires

about 5 percent of the time spent on reporting, or 5.67 hours per SNUN. Respondents submitting a SNUN, whether for a new or an existing chemical, use the same form to submit the information to EPA. As estimated in the currently approved ICR entitled Pre

-

Manufacture Review Reporting and Exemption Requirements for New Chemical Substances and Significant New Use Reporting Requirements for Chemical Substances ( EPA ICR No. 0574.13; OMB Control No. 2070

- 0012) , and as anal yz ed throughout section 2 of this appendix and in the economic anal ys is for the final rule, the reporting burden for a new chemical SNUN is 105 hours and the recordkeeping burden for a new chemical SNUN is 2 hours. The estimated 105 hours for a new chemical SNUN submission is the approximate mid

-point estimate of the range presented in Table 16. The estimated 2 hours for each SNUN recordkeeping reflects is an aggregate annualized recordkeeping burden is an assumption based on the recordkeeping burden associated with essential technical requirements, such as records that demonstrate that the first commercial batch of chemical manufactured for commercial purposes under the exemption met certain eligibility criteria. EPA is adjusting the estimated reporting and recordkeeping burden for an existing chemical SNUN from 113.25 hours to 105 hours and 5.67 hours to 2 hours, respectivel y, to ensure consistency

with SNUN
- related estimates presented in EPA ICR No. 0574.13 and in the economic analysis for the final rule.

3 .1.1 Impact of Adjusted Baseline Reporting and Recordkeeping Estimates As explaine d in section 3.1 of this appendix , to make this analysis consistent with that presented in EPA ICR No. 0574.13 for SNUN submission and recordkeeping, the baseline reporting burden for submitting an existing chemical SNUN is adjusted to the estimated mid

po int of 105 hours, rather than the upper

-bound estimate of 113.25 hours of reporting burden presented in EPA ICR No. 1188. 09
. This reporting burden adjustment results in a decrease of 82 annual hours. The recordkeeping burden for SNUN submission activitie s is also adjusted, from 5.67 hours per response to 2 hours per response. This recordkeeping adjustment results in a decrease of 37 annual hours. Thus, these baseline adjustments result in a burden decrease of 119 annual hours, from 1,189 annual hours to 1,070 annual hours (1,050 reporting hours and 20 recordkeeping hours.

### 3 . 2 Reporting Burden Program Changes Upon implementation of the final rule, the average annual existing chemicals reporting burden is estimated to be approximately 934 hours. As discus sed in section 1 of this appendix, respondents will incur new, company- leve l reporting burdens while realizing form

- level reporting burden savings. Company
- level reporting burden includes those activities that facilitate submission of an e - PMN : CDX registration, CDX electronic signature (i.e., authentication of identity and veri fication of authorization), setting up a Pay .gov account, and rule familiarization. Form
- level reporting burden includes completion and submission of Existing Chemical SNUNs. EPA projects that one

- third of first year submissions and two

- thirds of all se cond ye ar submissions will be made via CDX. All submissions must be made via CDX by the third year and beyond. The actual rates of adoption of CDX in years one and two of the rule could be higher or lower than EPA’s projections. However, lacking any dat a on which to base other projections, EPA assumes an even rate of adoption over the two

- ye ar phase

- in period.

3 .2.1 New Company- Level Reporting Burden s EPA estimates that the e - PMN rule will impose an average program change increase of 12 annual burden h ours on respondents and is associated with the time required to complete company- level paperwork activities related to the final e - PMN rule requirements, i.e., CDX Registration, CDX e lectronic s ignature, E

- Pay ment (Pay .gov ID) 2 

### , and Rule Familiarization. These activities and related burdens are explained in full in the supporting statement for EPA ICR No. 2327.07 (OMB Control No. 2070

- 0173). The activities are also included in the burden anal ys is presented in Tables 18 through 20. As indicated in Table 18 company- level burdens are higher in the first year due to initial rule familiarization burdens that not incurred in subsequent ye ars . 3 .2.2 Reductions in Form- Level Reporting Burden for Existing Chemical

SNUN Submissions In addition to the baseline adju stments described in section 3.1 of this appendix, respondent adoption of electronic preparation and submission under the e - PMN rule will further

2 Use of Pay.gov to remit the SNUN submission fee is not be mandatory under the final e

- PMN rule, but EPA assumes cons ervatively in the Economic Analysis for the final e

- PMN rule that SNUN submitters will send the fee via a Pay.gov account.

### affect the reporting burden estimates for existing chemical SNUNs. The adoption of electronic

preparation and submission through CDX using the e

- PMN software to prepare and submit existing chemical SNUNs will bring about burden savings b y creating administrative efficiencies and time savings. Specifically , EPA estimates that the reporting burden will be reduced from 105 hours per submission to 92.2 hours per submission, saving 12.8 hours per response. The net impacts of these changes, coupled with the new rule related burdens described in section 3.2.1 of this appendix, are demonstrated in Tables 18 through 20. Because the final e - PMN rule phases

- in the use of CDX over the three

- ye ar period, the number of companies and forms using CDX will vary across the phase

- in period. Therefore, burden hours are presented separatel y for each ye ar of the phase

- in period. Prior to the e - PMN rule, only form
- level burden was estimated for existing chemical SNUNs . Due to new activities that will occur at the company

- level once electronic reporting via CDX is available, burden is broken out at the company and form level in the r ule

- related ICR. EPA is assuming an even rate of adoption over the two

- ye ar phase

- in period. For existing chemical SNUNs, this means that EPA is assuming that companies will incur the burden associated with CDX registration, completing the Electronic Signature A greements, and setting up a Pay .gov account to submit the TSCA fee, at the rate of 3.3 (10/3) additional companies in each of ye ar of the ICR’s approval. At that point, all SNUN submissions will be made via CDX. Tables 18, 19 and 20 present the respondent reporting burden associated with this information collection during the first 3 years of rule implementation. The form

- level during each of these ye ars is estimated to total 922 hours. This burden estimate is calculated b y multiplying the hour s of reporting burden b y the number of existing chemical SNUNs that EPA expects to receive. Note that burden is adjusted to reflect the savings associated with the e - PMN rule in each ye ar of the phase

- in period , and also reflects adjustments to the existing chemical SNUN baseline reporting burden for consistency purposes . Because all existing chemical SNUNs must be generated using the new e - PMN software beginning in the first year following rule promulgation, however, form completion burden saving will b e realized by all submitters immediately
. After accounting for the baseline adjustments described in section 3.1.1 of this appendix, the estimated 922 annual hours of form

- level reporting burden reflects a 128 hour program change reduction.Table 18 Revised Existing Chemical SNUN Reporting Burden Under the e - PM N Rule, Year 1

### 3 . 3 Existing Chemicals Recordkeeping Burden Program Changes Respondents will not incur any company- level recordkeeping burdens
. Rather, they will realize f orm - level recordkeeping burden savings related to el ectronicall y s ubmitted existing chemical SNUNs. Upon the rule’s effective date, all respondents will be required to use the e

PMN software to prepare their submissions and therefore will realize immediate reporting burden savings. However, not all respondents will realize immediate recordkeeping burden savings. As described in section 1.1.2 of this appendix, recordkeeping and postage savings will be realized in years when electronic reporting via CDX is used . Reductions in recordkeeping burden are contin gent upon adoption of electronic submission via CDX. Once a respondent electronically submits an existing chemical SNUN , the burden for maintaining or updating related records is minimal. EPA expects that 33 percent of respondents to submit existing chemical SNUNs electronically via CDX in the first year, 67 percent will do so by the second ye ar, and 100 percent will do so by the third ye ar (when all respondents are required to submit electronically)
. As discussed in section 3.1.1 of this appendix, the ex isting chemicals SNUN

- related recordkeeping burden was adjusted from 5.67 hours per SNUN to 2 hours per SNUN ensure consistency with burden estimate s for new chemical SNUNs
. EPA expects that respondents submitting existing chemical SNUNs will experience the same reporting and recordkeeping burden savings as respondents submitting new chemical SNUNs (i.e., one technical and one clerical staff member are estimated to each save 30 minutes on recordkeeping, for a total recordkeeping burden of one hour, as CDX is adopted)
. EPA therefore assumes that recordkeeping burden will be reduced b y half (from 2 hours to 1 hour) due to the efficiencies in creating and storing SNUNs and supporting documents electronicall y.

### Table 21 shows that in the first year of the ICR approval period, when EPA assumes

three companies will submit SNUNs via CDX, the total recordkeeping burden is estimated to be 17 hours. By

year three, when all 10 existing chemical SNUNs expected each ye ar will be submitted via CDX, the total record keep ing drops to 10 hours. The total three

- ye ar recordkeeping burden is estimated to be 40 hours, or an annual average of slightly more than 13 hours. Table 21 Revised Respondent Recordkeeping Burden For Existing Chemical SNUNs Under the e - PM N Rule, Years 1 through 3

### 4.0 Summary of Net Changes to Annual Paperwork Burden Estimates

4.1 Adjustments Adjustments to baseline estimates for both of the ICRs addressed in this appendix are responsible for notab le changes in EPA’s overall annual burden estimates. The baseline adjustments to EPA I CR Nos. 0574.13 and 1188.09 are responsible for a combined reduction of 14,753 burden hours. This section of this appendix summarizes those adjustments.

4.1.1 Fewer New Chemicals Responses EPA estimated the annual number of new chemicals

- related submissions over a 5

- ye ar average and the adjusted that annual average b y 15 percent to count onl y valid submissions. In previous ICR renewals, EPA would have based its projec tion, in part, on the average number of annual responses submitted in the previous 3 ye ars. This change led EPA to estimate that 203 fewer net responses would be submitted annually across all types of activities covered under this ICR. The result of this change is an estimated net decrease of 14,634 reporting and recordkeeping hours. This adjustment is addressed in section 2.1 of this a ppendix. 4.1. 2 Harmonized SNUN Reporting and Recordkeeping Burden Estimates Respondents submitting a SNUN, whether for a new or an existing chemical, use the same form to submit the information to EPA. However, EPA had utilized different points in the same estimated burden range when developing separate reporting burden associated with SNUNs for ICR Nos. 0574.13 and 1188 .09. The reporting burden estimate presented in IC R No. 0574.13 reflected the approximate mid

-point of the estimated burden range (105 hours), while the reporting burden estimate presented in IC R No. 1188.09 reflected the high

- end of the same estimated burden range (about 113 hours). To ensure consistent anal ys is, EPA harmonized the SNUN reporting burden estimates for both new and existing chemical SNUNs by utilizing the mid

-point of the range (105 hours). The application of this harmonized estimate to EPA ICR No. 1188.09 results in an adjustment decrease of about 82 annual reporting burden hours. Similarly, EPA had utilized different SNUN

- related recordkeeping estimates when developing the annual burden estimates for IC R Nos. 0574.13 and 1188.09 (2 hour s and 5.67 hours, respectively , per SNUN). Again, to ensure consistent anal ys is, EPA harmonized the SNUN
- related recordkeeping burden estimates for both new and existing chemical SNUNs by adopting the SNUN

- related recordkeeping estimate of 2 hours per SNU N as presented in ICR No. 0574.13 . As explained in sections 2.3.1 and 3.1 of this appendix, the estimated 2 hours for each SNUN recordkeeping reflects an aggregate annualized recordkeeping burden and is an assumption based on the recordkeeping burden asso ciated with essential technical requirements , such as records that demonstrate that the first commercial batch of chemical manufactured for commercial purposes under the exemption met certain eligibility criteria. The application of this harmonized estimate to EPA ICR No. 1188.09 results in an additional adjustment decrease of about 37 annual recordkeeping burden hours.

### 4.2. Program Chang es

The net impact of the e

- PMN rule is an estimated 15 , 567 hour administrative

- level program change burden reduction on TSCA section 5 respondents. This section of this appendix summarizes those program changes.

4.2.1 Modest Rule Implementation Burden EPA estimates that the e - PMN rule will impose an average program change increase of 3 65 annual burden hours on both new and existing chemical respondents submitting TSCA section 5 notices (353 hours + 12 hours, respectively). This estimate reflects modest start

- up burden associated with CDX registration, obtaining a CDX e lectronic s ignature, optional E
Pay ment ( establishing a Pay .gov ID), and Rule Familiarization . E ach of these activities will facilitate electronic preparation and submission of TSCA section 5 notices to EPA, which in turn will bring about burden reduction for respondents. Company

- level rule

- implementation burdens are higher in the first year due to initial rule familiarization burdens which are not incurred in subsequent years.

4.2.2 Resulting Burden Reduction The 365 annual burden hours of new, company- level burden is offset by a program change reductio n of 14,972 annual form

- level reporting burden hours on both new and existing chemical respondents submitting TSCA section 5 notices (14,844 hours + 128 hours, respectivel y). These form

- level burden reductions will be realized immediately because the reductions are attributed primarily to the electronic preparation of TSCA section 5 notices. In addition, new and existing chemical respondents will realize a program change reduction of an average 960 annual burden hours (947 hours + 13 hours, respectively) over the first 3 years. 4.3 Net Changes EPA projects that the combined burden adjustments and program changes result in a net burden reduction of 30 , 320 annual hours. Adjustments combine for a net decrease of 14,753 annual burden hours for both new and existing chemical respondents. Program changes combine for a net decrease of 15,567 annual burden for both and existing chemical respondents.
