1 **Supporting Statement for a Request for**  **OMB Review under the Paperwork Reduction Act**  **1 IDENTIFICATION OF THE INFORMATION COLLECTION**  **1(a) Title and Number of the**  **Information Collection Title:**  **Health and Safety Data Reporting, Submissio n of Lists and Copies of**  **Health and Safety Studies**  **EPA ICR No. :**  **0575. 1**  **5 OMB Control No.**  **: 2070**  **- 0004**  **1(b) Short Characterization**  On September 2, 1 982, EPA promulgated the fin al Toxic Substances Control Act (TSCA) (15 U.S.C. 260 7(d) ; see Attachment 1 and http://www.epa.gov/lawsregs/laws/tsca.html ) Section 8(d) Health and Safety Data Reporting Rule (40 C.F.R. Part 716 ; see Attachment 2 and http://www.access.gpo.gov/nara/cfr/waisidx_03/40cfr716_03.html )
. The Model Rule was revised by amendments on September 15, 1986 (51 FR 32720) and April 1, 1998 (63 FR 15965). The Model Rule describes the requirements and procedures for submitting lists and copies of unpublished health and safety studies under section 8(d) of TSCA (40 CFR 716)
. Itrequires manufacturers and (if specified) processors to submit lists and copies of health and safety studies relating to the health and/or environmental effects of the chemical substances and mixtures listed in the TSCA section 8(d) rule
. The listed chemical substances and mixtures include chemicals recommended for testing under section 4 b y the Interagency Testing Committee (ITC) and other chemical substances that EPA (particularl y the Office of Pollution Prevention and Toxics (OPPT)), or other federal agencies, wish to assess for health or environmental effects
. EPA amends the TSCA section 8(d) rule periodicall y t o add chemical substances and mixtures. To comply with the reporting requirements of the rule, the respondents (manufacturers and processors) must search their files to identify any health and safety studies in their possession, copy

and process the relevant studies, make lists of studies that are current ly in progress, and review the studies for confidential business information. All studies submitted to EPA will be verified and the contents of the submissions recorded and inspected for the inclusion of confidential business information
. C opies of the d ocuments will then be prepared and distributed, based on the associated chemical identity , to program offices at EPA and/or to other federal agencies for scientific anal ys is
. A coding form will be completed to capture certain descriptive information such a s identity , document control number, confidentiality indicator, document title, document date, receipt date and chemical i dentity
. The document will be stored electronically for archival purposes.2

EPA will use the studies to support its investigation of the risks posed b y listed chemicals and, in particular, to support its decisions on whether to require industry to test chemicals under section 4 of TSCA. The total economic burden imposed by TSCA section 8(d) on the regulated community is estimated at 1,6 05 hours with an associated cost of $ 116,551 (119 respondents). The total estimated respondent burden is based on a rate of chemical addition s of 70 chemicals per year . **2 NEED FOR AND USE OF THE COLLECTION**  **2(a) Need/Authority for the Collection**  TS CA section 8(d), 15 U.S.C. 2607(d), requires EPA to promulgate rules requiring persons who manufacture, process or distribute, or propose to manufacture, process or distribute chemical substances and mixtures, to submit to EPA lists and copies of health an d safety studies in their possession
. OPPT reviews these studies to determine the kinds of testing needed to fill the information gaps in known effects of the listed chemicals, to make decisions during the risk assessment process, and for considering control actions
. Other federal agencies use the studies when they

are assessing a listed chemical substance for health or environmental effects. **2(b) Use/Users of the Data**  Studies submitted pursuant to TSCA section 8(d) rules will be evaluated in conjunctio n with other available data
. EPA and other federal agencies will use the data to construct a complete picture of the known effects of the chemical substance
. From this picture, OPPT will be able to determine what kinds of testing, if any, are needed
. The T SCA section 8(d) studies will ensure that OPPT bases its testing decisions on the most complete information available and does not require testing that may have already

been done. In addition, EPA will require that copies of health and safety studies be submitted on other chemicals that are under investigation either in the earl y stages of risk assessment or when action to control exposure is being considered b y EPA or another federal agency
. These chemicals may

be ones for which persons have submitted substantial risk notification under TSCA section 8(e), or other chemicals for which data are needed to support a control measure under sections 5 and 6 of TSCA or under other EPA
- administered statutes
. If this information collection did not exist, EPA would not be able to obtain the necessary information for evaluating the need for testing under section 4 of TSCA or controlling chemical substances under TSCA sections 5 and 6. Inthe past, the following offices have also utilized submitted studies: the Offi ce of Air and Radiation (OAR) for developing Tier II anal yses; the Office of Research and Development (ORD) for developing extended risk assessments; the Consumer Product Safety Commission (CPSC) for assessing the hazards of known consumer exposure; the Am erican Council for Government Industrial Hygienists (ACGIH) ; and the National Institute for Occupational Safety and Health (NIOSH) for developing recommended occupational exposure levels.3

**3 NON**  **- DUPLICATION, CONSULTATIONS AND OTHER COLLECTION**  **CRITERIA 3(a)**  **Non -**  **Duplication** In drafting a TSCA section 8(d) rule, EPA considers all available information, i.e. , published and unpublished literature, databases, and all data available from EPA programs and offices and other federal entities
. If existing data are sufficient for assessment or control purposes, EPA will not require TSCA section 8(d) reporting
. However, if that information is not sufficient, or is obtained in a way that makes EPA doubt its validity, then the Agency must require the submission of no n - published health and safety studies. The health and safety studies to be submitted under the TSCA section 8(d) rule are not available from any other source
. The TSCA section 8(d) rule requires the listing and submission of studies that are conducted in
- house b y industry or by industry contractors and not published in the scientific literature
. Under the revisions to the Model Rule promulgated in September 1986, respondents do not have to list or submit any studies that have been published in the scienti fic literature, or submitted previously to OPPT on a non
- confidential basis
. Studies that respondents previously have submitted on a non
- confidential basis to other EPA offices or programs need only be listed. **3(b) Public Notice Required**  **Prior to ICR Subm ission to OMB**  Inproposing to renew this I CR, EPA provided a 60
- day public notice and comment period that ended on May 29 , 2015 ( 80 FR 16672 , March 30 , 2015 ). EPA received no comments during the comment period. **3(c) Consultations**  Under 5 CFR 1320.8(d)(1), OMB requires agencies to consult with potential I CR respondents and data users about specific aspects of I CRs before submitting an I CR to OMB for review and approval. In accordance with this regulatio n, EPA submitted questions to nine parties via e
- mail. The individuals contacted were: Scott Jensen American Chemistry

Council Scott_Jensen@AmericanChemistry .com Jenny Gaines Specialty Chemical Manufacturing Association gainesj@socma.com Dan Turner E. I . du Pont de Nemours and Company Daniel.a.Turner@dupont.com4

Eric Wohlschlegel American Petroleum Institute wohlschlegele@api.org Melissa Scanlan Environmental Law Center, Vermont Law School MSCANLAN@vermontlaw.edu Stacy Cooks Asthma & Allergy Foundation of America stacy @aafa.org Shary n Stein Environmental Defense Fund sstein@edf.org Ken Cook Environmental Working Group ken@ewg.org David Goldston Natural Resources Defense Council eheyd@nrdc.org EPA received no responses to its solicitation for consultations. A copy of EPA’s consultation e
- mail to the above potential respondents is included in Attachment 3
. **3(d) Effects of Less Frequent Collection**  In most instances, respondents will be required to make only initial submissions under the TSCA section 8(d) rule
. However, after the initial submission of lists and studies, respondents are required to notify

EPA when certain health and safety studies are initiated by submitting a list of newl y initiated studies
. Because the reporting frequency for the TSCA section 8(d) rule is generall y once, the reporting frequency cannot be reduced without suspending the information requirement
. If this were to happen, EPA would not be able to obtain the necessary information for evaluating the need for testing under section 4 of TSCA or controlling chemical substances under sections 5 and 6 of TSCA. **3(e) General Guidelines**  This information collection activity is necessary

to implement the statutory requirement s of section 8(d) of TSCA and is consistent with the requirements of the PRA, OMB implementing regulations (5 CFR 1320.6), and OMB Guidance.5

**3(f) Confidentiality**  Under the TSCA section 8(d) rule, a person submitting a health and safety study may claim certain parts of the study confidential
. EPA has implemented procedures to protect confidential, trade secret and proprietary information from disclosure
. These procedures compl y with EPA’s confidentiality regulation, 40 CFR Part 2, Subpart B. **3(g) Sensitive Questions**  This section is not applicable
. The information request ed is not sensitive in nature. **4 THE INFORMATION COLLECTED**  **- AGENCY ACTIVITIES, COLLECTION**  **METHODOLOGY, AND INFORMATION MANAGEMENT 4(a)**  **Agency Activities** The activities routinel y conducted b y EPA related to the rule development, processing, anal ys is and storage of the information collected under this rule include the following: 1. Review and select chemicals; 2. Develop and issue an amendment to the TSCA section 8(d) rule to add the substances or mixtures; 3. Answer respondents’ questions; 4. Process and anal yz e rule submissions, including requests for confidentiality; and 5. Maintain and distribute the data. **4(b) Collection Methodology and Management**  EPA’s current collection methodo logy and information management s ys tem is based on the current requirements in 40 CFR 716.30 and 716.35 for the submission of electronic copies , which was implemented by a rule published in the Federal Register on December 4, 2013 (78 FR 72818)
.To aid p ersons subject to this information collection, OPPT has set up a TSCA Hotline that provides information regarding TSCA section 8(d) reporting as well as other regulatory information. When Hotline staff are unable to answer questions regarding TSCA section 8(d), the questions are referred to OPPT staff for appropriate resolution. All Non
- Confidential Business Information submitted under TSCA section 8(d) is placed in the OPPT public docket, indexed and available for public inspection
. A vast majority of TS CA section 8(d) submissions to date are reflected in the TSCA Test Submissions (TSCATS) database, a publicly

available and searchable database. **4(c) Small Entity Flexibility**  The TSCA section 8(d) rule applies to all manufacturers and processors of chemicals and6

others in possession of studies, regardless of size
. However, EPA does not anticipate that many small businesses possess health and safety studies because they are unlikel y to have the financial resources to perform the studies on chemicals s ubject to the rule
. Therefore, the burden on such companies should be minimal. **4(d) Collection Schedule**  The collection sched

uled under this I CR is chemical
- specific in nature and occurs once in an es tablished time frame between 60 day s and 2 years . Rep orting of information is only required when the subject matter information (i.e., the lists of studies and final study reports) is available
. Availability

of study reports on the list may

occur after the established reporting period for the list, and must still be submitted when they become available
. In any case, submission of the list or any study report for a listed study

occurs once for each chemical covered by

a TSCA s ection 8(d) rule. Studies previously submitted to OPPT are exempt. Amendments addi ng substances are made to the Health and Safety Data Reporting Rule subsequent to the ITC’s semiannual addition of substances and categories of substances to the TSCA section 4(e) Priority L ist
. Other substances are added when there is a demonstrated need for the information. **5 THE RESPONDENTS AND THE INFORMATION REQUESTED**  **5(a) Respondents/NAICS Codes**  Respondents affected b y this collection activity are identified mainly

by North American Industry Classification Sy stem (NAICS) codes 325 (chemical manufacturing and allied products) and 32411 (petroleum refiners). **5(b) Information Requested**  (i) Data Items Persons who manufacture (including import) chemical substances and mixtures, or propose to do so, and processors of such substances and mixtures (if specifically identified in a particular rule) must submit copies of the unpublished health and safety studies in their possession for the listed substances or mixtures
. They must also submit lists of reportable studies that they initi ate or, about which they know, for each of the listed substances or listed mixtures. All submitted studies must be accompanied b y a cover letter that contains the following data (40 CFR 716.30):

• Name,
• Job title,
• Address , and
• Telephone numbers of the submitting official.
• Name and address of the manufacturing or processing establishment on whose behalf7 the submission was made
• Id entify

any impurity or additive known to have been present in the substance or l isted mixtures as studied, unle ss so noted in the study
. • Id entify

that the study

is being submitted under Part 716. Respondents may

voluntarily

choose to develop and submit robust summaries of the full toxicological study

reports in conjunction with the submitted full study reports . Th e robust summaries should contain technical information to adequatel y describe the study and results, and should be written such that the information provided is sufficient to allow a technicall y qualified person to evaluate study

results without needing t o review an entire study report . Ty picall y, a robust summary

would include a description of the test substance, methods, results, conclusions, data quality

description, and references associated with the full study
. List of studies shall include (40 CFR 716.35): (1) ongoing health and safety studies conducted b y or initiated by them; (2) studies they know about but do not have copies of; and, (3) studies that have been sent to another federal agency with no claims of confidentiality
. For ongoing health and safety studies conducted by or initiated for the respondent, the list should include the following data:
• Beginning date of the study
• Purpose of the study
• Ty pes of data to be collected
• Anticipated date of completion
• Name and address of the laboratory con ducting the study For studies known to the respondent but for which they do not possess copies, the list should include the following data:

• Name and address of a person known to them th at possess a copy of the study
. For studies previousl y sent to a federal agency with no claims of confidentiality , the list should include the following data:

• Title of the study
• Name and address of the person to whom the study was sent
• Month and year in which the study was submitted (ii) Respondent Activities A repre sentative respondent would engage in the following activities in order to produce the lists of studies and required data listed in section 5(b)(i) of this supporting statement: 1. Determine whether the firm may be required to report
. If so, review the rule i n more detail; 2. Conduct a corporate review to identify which firm sites must be searched to locate the8

appropriate health and safety studies; 3. Search the files at appropriate sites to locate relevant studies; 4. Compile and transcribe lists of studies being sub mitted, ongoing studies, newly initiated studies, studies known to exist but not known to be in the respondent’s possession, and studies previously

submitted to other f

ederal agencies without confidentiality claims; 5. Photocopy

the studies; 6. Voluntarily

prepare robust summaries of the studies; 7. Review the responses for possible confidential business information; and 8. After initial study

submissions, notify

EPA when other studies are initiated; submit studies completed after the reporting period
. **6 ESTIMATING THE COST AND BURDEN OF THE COLLECTION**  The methodology

used for estimating the burden and costs to industry resulting from the addition of chemicals to the TSCA section 8(d) rule over the next three years is derived from the previous infor

m ation collection request (I CR). EPA has added chemicals to the TSCA section 8(d) list on an episodic basis
. As shown in Table 1, chemicals have been added to the list three times since 1996 , yielding an average of 15 chemicals per year for the years betwe en 1996 and the present
. EPA use s a basis of 70 chemicals per year for the 201 5
- 2018 ICR period, using information from the 2006 rulemaking , which added 208 new chemicals (averaging 69 chemicals per year during the 2006
- 2009 I CR p eriod)
. **Table 1 .**  **Number of Chemicals Added to the**  **TSCA Section 8(d) Reporting List .**  **Year** 1996 1997

Year **Number of Chemicals**  47 0 15 0 208 0 15 * EPA issued a TSCA section 8(d) rule (71 FR 47130) on August 16, 2006 for 243 HPV chemicals that were not sponsored in the voluntary portion of the HPV Challenge Program
. EPA later withdrew 33 of these chemicals in a final rule issued on September 29, 2006 (71 FR 57439)
. In a subsequent direct fina l rule issued on April 30, 2007, EPA removed two additional chemicals (72 FR 21119), resulting in a total of 208 chemicals subject to Section 8(d) reporting. Moreover, to characterize the reporting implications per chemical addition associated with Section 8(d) reporting (including information from the 10
- ye ar period prior to the 2006 TSCA section 8(d) rule ) , this analy sis use s TSCA IUR data from the 1998, 2002, and 2006 reporting cycles. 1 Table 2 summarizes the models and bases, as appli ed to the 20 15
- 2018 ICR
1 According to 40 CFR 716.5, persons are required to report under a TSCA section 8(d) rule if, during the 10 years preceding the effective date of the rule, they manufactured (including imported) or planned to manufacture (including import) a listed chemica l. The IUR data for this analysis is not limited to reporting from chemical manufacturers and petroleum refiners. This scope does not affect the accuracy of the results, given that only firms regulated under TSCA 8(d) submit reports.9

**6(a) Estimating Respondent Burden**  Firms will undertake a number of actions in response to a TSCA section 8(d) listing and the unit burden associated with each of these tasks is discussed in detail below. Review the Rule
. Firms in the relevant industries that may have unpublished health and safety studies will have to determine whether they manufacture a listed chemical and may thus be required to report
. If so, they will have to review the rule in detail to understand its requirements, such as the ty pes of health and safety

studies EPA is asking for, the grade or purity of the test material, and the time frame of the reporting period
. Note that , unless EPA specifies otherwise, the coverage of 8(d) rules is limited to chemical manufacturers and petroleum refineries
. Most firms in these industries will not manufacture a listed chemical, and many will spend a de minimis amount of time making that determination
. Those firms that manufacture a listed chemical must review th e rule to understand its specific requirements
. This is estimated to take an average of 2 hours of managerial time for each firm manufacturing a listed chemical. Conduct Corporate Review for Site Identification. Firms that manufacture a listed chemical wi ll need to conduct a corporate review to identify which of the firm’s sites must be searched for appropriate health and safety studies
. This corporate review is estimated to require an average of 3 managerial hours per firm. Conduct Site File Search
. Firm s that manufacture a listed chemical must search the files at appropriate sites to look for studies that are responsive to the TSCA section 8(d) rule
. It is estimated that the search will take an average of 3 hours of technical time per site
. EPA estimates that each firm will have an average of 1.5 sites manufacturing a listed chemical. This yi elds an average burden of 4.5 technical hours per firm for site file searching (3 hours per site * 1.5 sites per firm)
. Provide Study

Title Lists
. Respondents are required to submit lists containing the titles of any studies being submitted, titles of studies that are initiated or ongoing during the reporting period but that have not ye t been completed , titles of any unpublished studies that the resp ondent knows to exist but does not have in its possession, and titles of studies previously submi tted to other f ederal agencies w ithout confidentiality claims. Prior to electronic reporting, an average of 1 hour of clerical time per firm was estimated to b e dedicated to transcribing the list of study titles
. EPA expects that the major burden of compiling this list was incurred during the file search and would already be available in electronic format; therefore, there is no additional burden associated with this activity
. Prepare Robust Summaries
. Respondents may choose to develop and submit robust summaries of the full toxicological study reports . The robust summaries should contain technical information to adequately describe the study and results, and sh ould be written in such a way that the information provided is sufficient to allow a technicall y qualified person to evaluate study results without needing to review an entire study report . Ty picall y, a robust summary would include a description of the tes t substance, methods, results, conclusions, data quality11

description, and references associated with the full study
. It is estimated that 8 to 16 hours of technical time are needed to develop and review a robust summary , depending on the type of study cond ucted
. This IC R assumes an average of 12 hours of technical time to prepare a robust summary . Because submission of robust summaries is voluntary , EPA does not expect that many companies will undertake this activity
. EPA estimate s that each firm will submit an average of 9 studies, with 10% of those studies including a robust summary ; therefore, EPA expects to receive an average of 0.9 robust summaries per firm submitting studies , which we round up to 1 robust summary per firm submi tting studies
. The estimated average burden per robust summary is 1 2 hours of technical time. Review Responses for Confidential Business Information (CBI)
. Firms will need to review responses for possible CBI and delete any material that is considered by the firm to be CB I from one cop y of the study
. A separate cop y of the study must b e submitted without deletions of CBI
. CBIreview is estimated to take an average of 1 hour of managerial time for each study. Since each of the 20 firm s is submitting an aver age of 9 studies, CBI review results in an estimated average of 9 hours of managerial time per firm. Post
- Reporting Period : Submi t Ongoing or Newly
- Initiated Studies. Firms that have an ongoing or newl y- initiated study during the reporting period are required to provide EPA with a copy of the study

once it is completed
. CBI review and submission of ongoing or newl y- initiated studies are estimated to require an average of 1 hour of managerial time.

This weight reflects that for every firm that has to check for reports: 17% will submit reports , of which 1 firm (about 5% ) will provide robust summaries and 5% (about 1 firm) will provide a second response. ** Basis of 1.5 sites per firm These unit burden estimates are average values
. Large multi
- divisional, multi
departmental firms may

require more than the average time to comply
. However, there are smaller firms that are less complicated, and these firms may have a simpler process that requires less time.12

**6(b) Est** **imating the Respondent Universe** The number of chemicals added to the section 8(d) list has varied significantly from ye ar to year and has been zero in many years . EPA has added a total of 270 chemicals to the list since 1996 (47 in 1996, 15 in 2004, and 208 in 2006), which is an overall program historical average of approximately

15 chemicals p er ye ar . For estimates in this I CR, EPA assumes that an average of 70 chemicals per ye ar will be added to the section 8(d) list from 2015 to 2018, for a total of 210 chemicals over the three
- ye ar I CR period. Assuming that each chemical that is added to the list impacts 1.7 firms, then EPA expects 119 chemical manufacturing firms to be affected per ye ar by this ICR. Based on the reporting bases stated on Table 2, EPA assumes that 17% percent of the potentially

affected manufacturers will submit studies each ye ar, yi elding 20 firms submitting studies (0.1 7 * 119 manufacturers)
. Each submitting firm is expected to submit a total of 9 studies , yi elding an estimated total of 180 studies annually (20 firms * 9 studies per firm). A total o f 10% of the studies are expected to contain robust summaries, yielding a total of 1 robust summary per firm (9 studies * 0.10, and rounding up to 1) ; and 1 firm (5% of 20 firms) is estimated to submit a second response (for a newly initiated or ongoing st udy) after the reporting period ends. The number of firms estimated to engage in the various reporting activities is summarized in Table 4 . Note that not all respondents incur every aspect of reporting burden. For this analy sis, the conditions of the 200 6 rule and its reporting implications, along with the condition of 70 chemical additions per year, are assumed.

pes of response activities: searching files, submitting studies during the reporting period, and submitting studies after the reporting period
. The results are shown in Table 6
.13

**6(c) Estimating Respondent Cost**  Unit labor costs are calculated by adding fringe benefits and overhead to the wage or salary t o derive a full y loaded labor cost
. Costs are calculated for m anagerial, p rofessional/ t echnical, and cl erical workers
. Wages and fringe benefits for managerial, professional/ technical, and clerical labor are taken from the Bureau of Labor Statistics (BLS) Employer Costs for Employee Compensation (ECEC) manufacturing industry data f rom 2013
. The cost of fringe benefits such as pai d leave and insurance are taken from the same ECEC series for each labor category
. Fringe benefits as a percent of wages are calculated separatel y for each labor category
. Table 5 presents these results with fully loaded rates for managerial labor at $ 77.77 /h our; for technical labor at $ 67.59 /hour ; and for clerical labor at $ 30.35 /h our. **Table 5: Loaded Industry Wage Rates (December 2013) EPAB Labor**  **Category Data Sources**  **d Date**  **Wage Fringe**  **Benefit Fringes as**

. Assuming that 70 chemicals per year are added to the TSCA section 8(d) list and that reporting is similar to the 2006 experience, the average annual burden and cost per response is 31.5 hours and $2,282, respectivel y. Additionally , i n late 2012, EPA promulgated a dire ct final rule requiring the submission of unpublished health and safety data b y m anufacturers and importers of cadmium and cadmium compounds. As a result, the number of responses (1,384 responses) and burden hours (7,019 hours) for this rule were included in the OMB action notice for the most recent renewal of this information collection. Likewise, the respondent and burden hour totals were included in the OMB inventory

for this information collection. However, subsequent to the publication of the direct f inal rule, and subsequent to OMB’s most recent approval of the TSCA sec. 8(d) information collection, EPA withdrew the cadmium reporting rule. Consequently , EPA has eliminated from the current request for OMB approval of this information collection a total of 1,384 responses and 7,019 burden hours to reflect the withdrawal of the cadmium reporting rule. These values do not otherwise appear in any of the tables included in this section. **6(e) CDX Registration Activities to Enable Electronic Reporting**  EPA e stimates that respondents will incur a small amount of additional burden and costs in carryi ng out the additional paperwork activities that were imposed by the Electronic Reporting under the Substances Control Act (TSCA) Final Rule . This includes the burde n associated with activities that facilitate submission of an electronic report: CDX registration and CDX electronic15

signature. These activities occur onl y once for each submitter
. Some submitters may already have registered to use the e
- TSCAweb reporting tool in CDX (and obtained an accompanying electronic signature) in order to compl y with the mandatory electronic reporting requirements of EPA’s e
- PMN rule and/or IUR/CDR rule. Those submitters will not need to repeat the CDX registration and e
- signature process in order to file their health and safety studies . While there may be some overlap in the specific individuals already that have already

completed CDX activities, EPA is using a conservative assumption that all submitters who will file ele ctronicall y will need to register with CDX and, thus, incur associated burdens. This assumption may overestimate the burdens and costs actuall y experienced b y respondents. The one - time CDX burden includes the following: CDX Registration

– Based on the CROMERR Cost Benefit Anal ys is, EPA assumed that companies would spend 11 minutes per employee to register with CDX (EPA, 2004). Furthermore, EPA assumed that an average of four technical staff members and one manager would need to register for each company , resulting in 55 minutes of burden per firm
. CDX electronic signature (labor burden)

– Based on the CROMERR Cost Benefit Analy sis, EPA assumed that firms would spend 15 minutes preparing, submitting, and filing an electronic signature agreement (Authenti cation of I dentity) form to EPA per employee (EPA, 2004). One manager and four technical staff members per firm would incur this burden, totaling 75 minutes of burden per company. In addition, EPA estimates that a manager would spend an additional 30 minutes accessing, preparing, and submitting verification forms (Verification of Authorization) for all authorized submitters to EPA. The total burden incurred by firms submitting and then verifying electronic s ignature agreements would be 105 minutes. It should be noted that the burden associated with CDX Electronic Signatures does not include costs associated with contacting EPA’s CDX help desk to notify a change of submitter status, should one occur. **Table 7 .**  **Estimated Burden Associated with New CDX Registration Activities Inform**  **ation Collection**  **Estimated**

**6(f) Estimating Agency Cost**  The activities routinel y conducted b y EPA related to processing and storage o f the information collected under this rule include p rocess ing and anal yz ing the materials submitted under the rule , including requests for confidentiality ; and maintain ing and distributing data. The activities associated with Agency responses to TSCA sec tion 8(d) listings are assumed to be accomplished by a GS 13, Step 5 federal employee . The 2014 hourly wage rate for this level of emplo ye e in the Washington, D.C. locality is $4 8
. 83 per hour
. Adding 60% for benefits and overhead yi elds a loaded annual wage rate of $ 7 8.13 per hour. 2 As a result of the Electronic Reporting under the Substances Control Act (TSCA) Final Rule , EPA expects that the Agency will have a burden savings due to the elimination of the need to process paper forms, and reduced quality assurance/quality control (QA/QC) and O&M costs for the existing sy stem. Potential Agency burden savings associated with electronic reporting of TSCA section 8(d) health and safety studies were characterized based on information in the CDX Business Case Analysis regarding the estimated monetary benefit from using CDX. Of the six Program Data Flows studied in the CDX Business Case Anal ys is, monetary benefits from using CDX as compared to a paper submission baseline were quantified for two flows: TRI(Toxic Release Inventory) and e
-NOI (electronic Notice of Intent under the National Pollution Discharge Elimination System). Benefits ranged from eleven percent savings (e
-NOI ) to 22 percent savings (TRI) compared to the cost of the baseline process. For this IC R , EPA assumed an average annual burden savings of 16.5 percent. This percentage savings results in a total annual burden of 3,542 hours for electronic submissions. Th e estimated annual cost to the f ederal government for TSCA section 8(d) data collection totals $ 4,566.70 , for 58.45 hours , a s presented in Table 10

**6(g) Bottom Line Burden Hours and Cost**  As shown in Table 6 , if EPA adds 70 chemicals per year to the TSCA section 8(d) list during the time period covered b y this ICR, burden associated with 8(d) review and reporting will be incurred b y 119 firms. Note that not all these firms incur every aspect of reporting burd en . Those firms that do ultimately submit studies incur a small amount of additional burden and cost associated with registering with CDX in order to compl y with new electronic reporting requirements. The burden activities associated with CDX registration occur only once , during the first year of the ICR period. The average annual reporting burden and cost per response is estimated at 1 1
. 1 hours and $805.47 , respectivel y , with overall estimated annual totals of 1,552 burden hours and $112,766
. Conservatively

assuming that all firms submitting studies will need to complete a one - time CDX registration, the average annual burden and cost per CDX registration is 2.66 hours and $ 189
. 25 , respectivel y. This yi elds an estimated annual burden and cost pe r response for CDX
- related activities of 53.2 hours and $ 3 , 785
. As noted earlier, basing the future burden estimates on the reporting from the 2006 rule may overestimate reporting burden and cost if number and characteristics of the chemicals that are add ed to the TSCA section 8(d) list during the next three years are less burdensome than the 208 HPV chemicals that were added in 2006. Moreover, this ICR conservatively estimates that all submitters are new CDX registrants and will, therefore, need to incur the additional burden associated with registering with CDX and submitting an electronic signature agreement. EPA recognizes that some respondents may have already

registered for CDX in order to compl y with the mandatory

electronic reporting requirements of other TSCA collection activities; those respondents would not need to register again and would avoid the associated burden and cost altogether. The t otal annual respondent burden and cost for this collection ( sum of Tables 6 and 7) is 1,605 hours and $ 116,551 respectivel y. **6(h) Reasons f** 

**or Changes in Burden** There is a n et de crease of 6,778 hours (from 8 ,3 8 3 to 1, 605 ) in the total estimated respondent burden compared with that currentl y i n the OMB inventory
. This net de crease in burden is due to the following :
 The previous ICR incorrectly used a total of 1 robust summary per year as the total number of annual robust summary responses, yielding a total of 12 hours of annual burden. This ICR corrects this burden estimate by using a total of 20 robust s ummary responses per year, yi elding a total annual reporting burden of 240 hours

– an increase of 228 hours per ye ar.
 This I CR renewal incorporates changes made to Health and Safety Data reporting under TSCA section 8(d) that mandate the use of electronic reporting in lieu of traditional paper - based reporting. The new electronic reporting requirements eliminated the clerical18

burden associated with transcribing study title lists and photocopying studies for paper
based subm issions. This change resulted in a decrease of 40 hours to the average annual reporting burden. While electronic reporting serves to streamline and reduce the admini strative/clerical costs and burdens associated with submitting paper
- based health and safety studies, the burden savings were not sufficient to offset the new burden associated with CDX registration activities. However, it should be notes that these activities occur onl y once for each submitter and, since some respondents while most likely have already

registered with CDX, this analy sis conservativel y overestimates the burden and costs actuall y experienced b y respondents.

 The new electronic reporting mandate requires that submitters of health and safety data under TSCA section 8(d) register with CDX in order to submit studies el ectronically . The new annual burden associated with CDX registration activities is 53 hours.

 Finally , EPA has reduced the burden estimate by 7,019 hours to reflect the 2012 withdrawal of the cadmium reporting rule as noted above in section 6( d). **6(i) Burden Statement**  The annual public burden for this collection of information, which is approved under OMB Control No. 2070
- 0004, is estimated to average about 10.0 hours per response. Burden is defined in 5 CFR 1320.3(b)
