IDENTIFICATION OF THE INFORMATION COLLECTION
   	1(a)	Title and Number of the Information Collection
 	Title:	Collection of Information for TSCA Mercury Inventory Reporting 
	EPA ICR No.: 2567.03
	OMB Control No.: 2070-0207

	1(b)	Short Characterization/Abstract
As directed in the June 2016 Frank R. Lautenberg Chemical Safety for the 21st Century Act amendments to the Toxic Substances Control Act (TSCA), the U.S. Environmental Protection Agency (EPA)  is required  to assist in the preparation and publication in the Federal Register of an "inventory of mercury supply, use, and trade in the United States." Based on the inventory of information collected through this ICR, the Agency is directed to "identify any manufacturing processes or products that intentionally add mercury" and "recommend actions, including proposed revisions of Federal law or regulations, to achieve further reductions in mercury use."
EPA must publish an initial mercury inventory not later than April 1, 2017 and publish updates every 3 years thereafter. The Agency published its initial inventory report, "Mercury  -  U.S. Inventory Report: Supply, Use, and Trade," on March 29, 2017.
TSCA section 8(b)(10)(A) states "notwithstanding [TSCA] section 3(2)(B), the term `mercury' means . . .elemental mercury; and . . . a mercury compound." As such, the definition for mercury at TSCA section 8(b)(10)(A) supersedes the exclusions for "chemical substances" described in TSCA section 3(2)(B) that would otherwise apply to mercury, mercury-added products, or intentional uses of mercury in manufacturing processes. In particular, this interpretation would not exclude any "drug, cosmetic, or device" as described in TSCA section 3(2)(B)(vi), should such items contain mercury. Hereinafter, the use of the term "mercury" will refer to both elemental mercury and mercury compounds. 
Reporting is required from any person who manufactures (including imports) mercury or mercury-added products, as well as any person who otherwise intentionally uses mercury in a manufacturing process. The Agency promulgated the reporting requirements under 40 CFR 713. In order to avoid duplication, EPA coordinated the reporting with the Interstate Mercury Education and Reduction Clearinghouse (IMERC). 
Prior to developing its initial inventory report, EPA reviewed federal and state reports and databases, among other sources, in order to assemble a collection of available information on mercury, mercury-added products, and manufacturing processes involving mercury. Those sources include three databases applicable to mercury: the Chemical Data Reporting (CDR) rule, Toxics Release Inventory (TRI) program, and the U.S. International Trade Commission Interactive Trade (USITC) DataWeb. In reviewing data obtained, the Agency found that its baseline of data lacked the specificity and level of detail required to develop a mercury inventory responsive to TSCA section 8(b)(10)(D) or to be useful to recommend mercury use reduction efforts for both the public and private sectors. The Agency considers the national mercury inventory mandated by Congress to be an instrumental means to establish the requisite body of information to achieve those goals. As such, EPA is committed to further addressing such data gaps and to reduce the use of mercury in mercury-added products and manufacturing processes, as directed by TSCA section 8(b)(10)(C).
EPA is particularly interested in the amount of mercury in mercury-added products, as well as identifying various categories and subcategories of products. That amount would include quantities of mercury used to manufacture (other than import) mercury-added products in the United States, as well as quantities contained in imported and exported mercury-added products. Additionally, EPA determined that mercury used in manufacturing processes may not be reflected in amounts of mercury reported in other data collection systems. The inventory will help to close such data gaps by requiring periodic reporting from "any person who manufactures mercury or mercury-added products or otherwise intentionally uses mercury in a manufacturing process."  
EPA plans to use the collected information to fulfill statutory requirements to "every 3 years [after April 1, 2017], the Administrator shall carry out and publish in the Federal Register an inventory of mercury supply, use, and trade in the United States" and "identify any manufacturing processes or products that intentionally add mercury; and . . . recommend actions, including proposed revisions of Federal law or regulations, to achieve further reductions in mercury use." The Agency may also use such information to prioritize where and how measures are applied in order to help prevent potential risks of mercury exposure to human health and the environment. EPA continues to pursue measures to reduce the use of mercury in various media, including mercury-added products and manufacturing processes. As such, EPA intends to use information collected through this ICR to continue to reduce the use of mercury in products and processes and to facilitate reporting on implementation of the Minamata Convention on Mercury (Minamata Convention), to which the United States is a Party. The Minamata Convention is an international environmental agreement that has as its objective the protection of human health and the environment from anthropogenic emissions and releases of elemental mercury and mercury compounds.
NEED FOR AND USE OF THE COLLECTION
	2(a)	Need/Authority for the Collection
TSCA section 8(b)(10) requires reporting to assist in the preparation of "an inventory of mercury supply, use, and trade in the United States," where "mercury" is defined as "elemental mercury" and "a mercury compound." As per 40 CFR 713, reporting is required from any person who manufactures (including imports) mercury or mercury-added products, or otherwise intentionally uses mercury in a manufacturing process. EPA published its initial inventory report in the Federal Register on March 29, 2017, which noted data gaps and limitations encountered by the Agency in its historic reliance on publicly available data on mercury supply, use, and trade in the United States. As stated in the initial inventory report, "[f]uture triennial inventories of mercury supply, use, and trade are expected to include data collected directly from persons who manufacture (including import) mercury or mercury-added products or otherwise intentionally use mercury in a manufacturing process." These reporting requirements will help the Agency to prepare subsequent, triennial publications of the inventory, as well as execute the mandate to "identify any manufacturing processes or products that intentionally add mercury; and . . . recommend actions, including proposed revisions of Federal law or regulations, to achieve further reductions in mercury use" (15 U.S.C. 2607(b)(10)(C)). 
Pursuant to TSCA section 8(b)(10)(B), EPA interprets the scope of the mercury inventory to include sectors of the mercury market that fall under "supply, use, and trade of mercury in the United States." This includes activities implicit to the statutory description of persons who must report as stated in TSCA section 8(b)(10)(D)(i): manufacture, import, and intentional use in a manufacturing process.  EPA determined that additional activities are necessary to provide for a comprehensive inventory of mercury supply, use, and trade in the United States. For this reason, persons required to report to the mercury inventory must report information for the following activities: distribution in commerce, storage, and export. In sum, EPA intends that the mercury inventory will be a complete accounting of the amount of mercury in commerce.
Amendments to TSCA and Purpose of the ICR
On June 22, 2016, President Obama signed the Frank R. Lautenberg Chemical Safety for the 21st Century Act, which amends TSCA. Among other provisions that apply to mercury, Congress directed EPA to prepare and publish in the Federal Register an "inventory of mercury supply, use, and trade in the United States."
The primary purpose of this ICR is to support the development of that inventory, which will assist in its preparation. In turn, the inventory will help the Agency identify uses of mercury and recommend means to achieve further reductions of such uses in commerce. In addition, the Agency seeks to obtain the information necessary to achieve its goal to further reduce the use of mercury in products and certain manufacturing processes in order to prevent future releases to the environment, as well as assist the United States in reporting implementation under the Minamata Convention. EPA seeks to enhance its current information on how much mercury is used, in which products and manufacturing processes, and whether certain products are manufactured domestically, imported, or exported. 
Trends in Mercury Use 
Humans have mined, refined, and used mercury for a wide variety of purposes over thousands of years. In the United States, elemental mercury was mined until 1991 but today is produced only as a byproduct of metals mining or by recovering mercury from waste. In recent decades, mercury served as a catalyst in the chlor-alkali industry and in a variety of industrial, commercial, and consumer products. Due to its toxicity and replacement by new technologies, many uses of mercury have been discontinued in the United States, and the overall quantity has fallen dramatically in recent decades. For example, over the past three decades there has been strong downward trend of more than 97 percent in the use of elemental mercury in mercury-added products sold in the United States. In 1980, the United States used more than 1,800 metric tons of elemental mercury in mercury-added products annually. As described in the initial inventory conducted by EPA in 2017, approximately 40 metric tons of elemental mercury in products were sold in the United States in 2013. Many of these products sold have cost-effective, non-mercury substitutes. The United States also has traded elemental mercury and mercury compounds worldwide, although the Mercury Export Ban Act of 2008 prohibited the U.S. export of elemental mercury as of January 1, 2013.
Overview of Existing Information on Mercury-added Products and Manufacturing Processes  -  Availability and Limitations
Prior to developing its initial inventory, EPA reviewed federal and state reports and databases, among other sources, in order to assemble a collection of available information on mercury, mercury-added products, and manufacturing processes involving mercury. In reviewing data obtained, the Agency found that its baseline of data lacked the specificity and level of detail required to develop a mercury inventory responsive to TSCA section 8(b)(10)(D) or to be useful to recommend mercury use reduction efforts for both the public and private sectors. EPA is committed to further addressing such data gaps and to reduce the use of mercury in mercury-added products and manufacturing processes, where feasible.
The Agency determined that four online databases are applicable to the statutory directive to develop a mercury inventory. The CDR and TRI databases are part of EPA pollution prevention programs. IMERC is a state-level program related to mercury-added products. Lastly, the USITC DataWeb system is a federal program under the U.S. Bureau of the Census (Census). EPA reviewed these four databases and assessed their capabilities and limitations in relation to the mercury inventory. EPA's assessment of each database is explained below.  
Chemical Data Reporting Rule
EPA's CDR rule collects quantity information on chemical substances manufactured (including imported) or processed in the United States, including elemental mercury and various mercury compounds. In this regard, the CDR rule and this ICR could be complementary, albeit with some structural constraints. First, the CDR rule requires reporting when a person manufactures (including imports) for commercial purposes in excess of 2,500 pounds (lbs.) for elemental mercury and in excess of 25,000 lbs. for a mercury compound for a specific reporting year. Thus, this ICR will collect information on manufactured (including imported) quantities of elemental mercury and mercury compounds below those thresholds. 
Although the CDR rule in principal reporting years (i.e., the fourth year of every four-year reporting cycle) asks manufacturers (including importers) for information on end-uses of chemical substances, the amount of mercury used and the sector of industry lack specificity. Moreover, the CDR rule does not require reporting for chemical substances imported within articles. In concert with IMERC, this ICR will collect specific information on mercury-added products and the associated industry sectors. 
Toxics Release Inventory Program
The EPA TRI program requires facilities that manufacture, process, or otherwise use more than 10 lbs. of elemental mercury or mercury compounds during the calendar year to report amounts released to the environment or managed through recycling, energy recovery and treatment. While the TRI program does not require quantitative reporting for manufacturing, processing, or use activities by category, a facility is required to report activities and uses of the toxic chemical including, but not limited to "import," "for sale/distribution," "as a reactant," "as an article component," and "as a chemical processing aid."
EPA previously discussed how the information reported to the TRI program can be helpful in identifying and prioritizing facilities involved in the supply, use, and trade or mercury. However, information reported to the TRI program for activities that overlap with data elements in the this ICR lack specific quantitative amounts of elemental mercury and mercury compounds (e.g., reported as "check box" responses only). In addition, while maximum quantity of mercury on-site at a facility is reported in quantitative amounts, those amounts are broadly given in weight ranges. Moreover, the TRI program considers all mercury compounds as a single, generic category instead of distinguishing among specific mercury compounds. In its research to date, EPA has identified 69 mercury compounds of interest (see Section 4(b) Information Requested).
Interstate Mercury Education and Reduction Clearinghouse
Laws in certain states (Connecticut, Louisiana, Maine, Massachusetts, New Hampshire, New York, North Carolina, Rhode Island, and Vermont hereinafter referred to as "Notification States") require manufacturers and importers to identify the mercury products they sell and the volume of mercury contained within them. The volume information is reported in terms of national sales, although only companies selling mercury products within Notification States need to report. These data are reported online to IMERC, which is managed by the Northeast Waste Management Officials' Association (NEWMOA). Some states also collect information on mercury in products as part of separate programs. For example, under Washington's Children's Safe Product Act, manufacturers of children's products sold in Washington state are required to report products containing a "Chemical of High Concern to Children," including mercury. 
The IMERC database is a key source of national data on mercury used in products. The database houses information, which is provided by the private sector on a triennial basis per regulations in IMERC Notification States. The database provides a detailed picture of some aspects of the mercury product market. However, as reported by IMERC, there are limitations of the use of such data for this ICR and EPA's implementation of the Minamata Convention. For example:
 The data may underestimate the amount of mercury sold in products in the United States. The manufacturers, importers, and distributors in IMERC Notification States must report on mercury-added products sold in the United States, so the information is national in scale. However, if a mercury product is only sold in states other than the IMERC Notification States, then the product manufacturer, importer, or distributor is not required to report to IMERC. In addition, IMERC no longer collects data on a significant category of mercury-added products, specifically switches and relays, because these products are banned from sale in each of the eight IMERC Notification States.
 In other instances, the data may overestimate the total amount of mercury sold in products. In some cases, manufacturers supplied data for earlier reporting years, but are out of compliance for one or more years. Rather than assume that this non-reporting is a result of a company having phased-out its mercury-added product, IMERC takes a more conservative approach and assumes that the mercury total for non-reporters for the current reporting period is the same as the most recently reported year. 
 IMERC does not cover mercury compounds manufactured or imported for use in manufacturing processes or mercury-added products, with the exception of formulated products. 
 Companies report the amount of mercury in products they sell in the United States but not the amount in products they manufacture, import, or export.
IMERC's data limitations were also noted in 2013 by the Quicksilver Caucus, a coalition of state environmental association leaders dedicated to reducing mercury in the environment. 
U.S. International Trade Commission Interactive Trade DataWeb
The USITC DataWeb provides U.S. international trade statistics and U.S. tariff data to the public. All trade data are compiled from official data retrieved from Census. With the exception of exports to Canada, all U.S. merchandise export data is compiled from the Electronic Export Information filed by the U.S. Principal Party in Interest or their agents through the Automated Export System. Published data on U.S. imports of merchandise is compiled primarily from automated data submitted through the U.S. Customs' Automated Commercial System. Data are also compiled from import entry summary forms, warehouse withdrawal forms and Foreign Trade Zone documents as required by law to be filed with the U.S. Customs and Border Protection. 
Publicly available data in the USITC DataWeb may not be entirely accurate. Census describes certain reporting and data capture errors that can affect statistics, including: (1) mistakes or omissions made by importers, exporters, or their agents when reporting import or export shipments (e.g., missing or invalid commodity classification codes, missing or incorrect quantities or shipping weights, and missing, multiple, or incorrect state of origin designations); and (2) lost documents, errors in the on-line validations and edits of electronically reported data, and incorrectly keyed, coded or recorded documents.
In sum, EPA conducted a thorough review of publicly available information and databases that collect data germane to an inventory of mercury supply, use, and trade. EPA believes that it cannot develop an adequate national inventory using only these resources. Nonetheless, the Agency will attempt to leverage existing resources and avoid requesting duplicative data. The Agency believes that the ICR minimizes reliance on incomplete databases, assumptions, professional judgment, and anecdotal information, and maximizes the Agency's future ability to "identify any manufacturing processes or products that intentionally add mercury" and "recommend actions, including proposed revisions of Federal law or regulations, to achieve further reductions in mercury use."
Publication of the 2020 Mercury Inventory
On March 30, 2020, as required by the Frank R. Lautenberg Chemical Safety for the 21st Century Act, EPA published the first in a series of triennial reports on the supply, use, and trade of mercury in the United States (https://www.epa.gov/mercury/2020-mercury-inventory-report), supported by the Agency's mercury inventory reporting rule (an initial inventory report was published in 2017, prior to the rule that established reporting requirements). Based on the information collected under the mercury inventory reporting rule, the 2020 Mercury Inventory Report identifies any manufacturing processes or products that intentionally add mercury and recommends actions to achieve further reductions in mercury use.
Litigation Related to the Mercury Inventory Reporting Rule
In June 2018, EPA finalized a rule to require reporting from persons who manufacture (including import) mercury or mercury-added products, or otherwise intentionally use mercury in a manufacturing process. That rule was challenged in the Second Circuit Court of Appeals by the Natural Resources Defense Council and several state attorneys general in July 2018. The petitioners argued that three exemptions to the reporting requirements violated the statutory mandate within TSCA section 8(b)(10). Oral arguments were held on November 20, 2019 and the court issued its decision in June 5, 2020. The Agency prevailed on two issues, but the Second Circuit vacated an exemption (40 CFR 713.7(b)(2)) for persons who import pre-assembled products that contain a mercury-added component. As a result, such persons are now required to report pursuant to 40 CFR 713.7(b).EPA believes that requiring such persons to report would not require an adjustment to the estimated total of 756 manufacturers (including importers) or processors that could respond to this information collection, based on numbers of reporters of mercury data to the IMERC Database, as well as the EPA's TRI program and the CDR rule (discussed further in Part 6). In particular, the IMERC Database currently requires companies that import and sell mercury-added components to report and therefore the companies should already be reflected.  For reference, just over 100 persons reported to the Agency for the 2020 inventory which implies that our estimates are conservative. 
	2(b)	Practical Utility/Users of the Data
EPA will use the collected information to develop and publish an inventory of mercury supply, use, and trade in the United States. In addition, the Agency will use such information to fill gaps in existing data which will enable EPA to "identify any manufacturing processes or products that intentionally add mercury; and . . . recommend actions, including proposed revisions of Federal law or regulations, to achieve further reductions in mercury use." The information also could facilitate reporting on implementation of the Minamata Convention by the United States.
NON-DUPLICATION, CONSULTATIONS, AND OTHER COLLECTION CRITERIA
	3(a)	Non-Duplication
TSCA section 8(b)(10)(D)(ii) directs the Agency to "coordinate the reporting . . . with the Interstate Mercury Education and Reduction Clearinghouse" (IMERC) to avoid duplication. Furthermore, TSCA section 8(a)(5)(a) states "[i]n carrying out [TSCA section 8], the Administrator shall, to the extent feasible . . . not require reporting which is unnecessary or duplicative." The Agency seeks to avoid collecting data on mercury that would duplicate data already reported to existing state and Federal programs, and to coordinate with and complement those reporting programs as much as possible. 
After reviewing such reporting programs, EPA has designed the reporting requirements per 40 CFR 713 to reduce the burden for reporters already familiar with CDR, TRI, IMERC, and USITC DataWeb protocol. To do so, the Agency incorporated comparable reporting concepts and tools from each program and avoided requiring data that would be considered duplicative reporting, in an attempt to increase the efficacy of the reporting process while decreasing the burden of reporting to a national mercury inventory.
	3(b)	Public Notice Required Prior to ICR Submission to OMB
As part of the renewal process, EPA will publish a notice in the Federal Register prior to submitting the ICR to OMB. Pursuant to 5 CFR 1320.8(d), any public comments received will be placed in the EPA docket, EPA-HQ-OPPT-2020-0617, for this action. 
	3(c)	Consultations 
Under 5 CFR 1320.8(d)(1), agencies are required to consult with potential ICR respondents and data users about specific aspects of ICRs before submitting an original or renewal ICR to OMB for review and approval.  In accordance with this regulation, EPA will consult with representative stakeholders during the public comment period, see attachment 2. for examples of the consultation questions. 
	3(d)	Effects of Less Frequent Collection
EPA determined that the reporting and recordkeeping requirements of the ICR should be the minimum amount necessary in order to limit burden to industry while also supporting the mandatory triennial publication of the mercury inventory. Reporters are required to report once every three years and retain records for three years, commensurate with the three-year publication cycle set forth in the statute. If the Agency were to require less frequent reporting (i.e., more than three years between reporting cycles), then the information collected would not be timely given the triennial publication deadline.
	3(e)	General Guidelines
This ICR complies with the guidelines in 5 CFR 1320.5(d)(2). 
	3(f)	Confidentiality
Regulated entities may claim some of the information given to EPA as CBI. Reporting requirements will contain information for respondents on how to make a claim to EPA that all or part of their submitted information is CBI. EPA handles claims of confidentiality pursuant to established CBI procedures, as found at Section 14 of TSCA, 40 CFR Part 2, and the Agency's TSCA CBI Manual. CBI is also protected under the Freedom of Information Act (5 USC Section 525). 
	3(g)	Sensitive Questions
EPA will ask no questions of a sensitive nature.
THE RESPONDENTS AND THE INFORMATION REQUESTED
As directed by Congress, EPA will obtain required information directly from the entities that manufacture or import mercury or mercury-added products, as well as those that otherwise intentionally use mercury in a manufacturing process. To ensure that the scope of this ICR is sufficient without being overly broad, EPA reviewed existing databases (e.g., CDR, TRI, IMERC, and USITC DataWeb) in order to identify mercury-added products and product categories, manufacturing processes involving mercury, and relevant North American Industrial Classification System (NAICS) codes to include in the information collection.
	4(a)	Respondents and North American Industrial Classification System Codes
EPA interprets TSCA section 8(b)(10)(D) to identify three general categories of persons who must report under this ICR:
       Persons who manufacture (including import) mercury;
       Persons who manufacture (including import) mercury-added products; and
       Persons who otherwise intentionally use mercury in a manufacturing process.

	4(b)	Information Requested
            Data Items
As described in Section 2, EPA determined that the primary data elements required to establish a complete national inventory of mercury supply, use and trade are the amounts manufactured (including imported), stored, distributed in commerce, and exported.

            Respondent Activities 
Individuals who are contacted to participate in this information collection activity could potentially perform each of the following tasks:
       Compliance determination (i.e., read and understand applicability criteria to determine whether the respondent is subject to the rule); 
       Rule familiarization (i.e., read the final rule (83 Fed. Reg. 30054; June 27, 2018)) and reporting requirements/instructions);
       Preparation of reports (i.e., form completion/submission and CBI claim substantiation); and 
       Recordkeeping (i.e., prepare/submit report and maintain records (partial report) and prepare/submit report and maintain records (full report)).
THE INFORMATION COLLECTED: AGENCY ACTIVITIES, COLLECTION METHODOLOGY, AND INFORMATION MANAGEMENT
	5(a)	Agency Activities 
EPA resources will be devoted to reviewing and analyzing data submissions, maintaining files of submitted data, responding to public inquiries, and drafting and publishing the triennial mercury inventory. Specific Agency actions include:
 Requesting responses to the reporting requirements established by this ICR (83 Fed. Reg. 30054; June 27, 2018);
       Conducting outreach and providing materials to assist in understanding rule requirements and reporting data accordingly;
       Reviewing and performing quality assurance of submitted data; and
       Following up with respondents if clarifications are needed.
Based on the information collected, EPA plans to develop guidance and recommendations of actions to achieve further reductions in mercury use.
	5(b) 	Collection Methodology and Management
In order to streamline reporting processes, the data required to develop a comprehensive national mercury inventory will be collected electronically. In an effort to minimize burden to respondents and limit costs to the Agency, EPA is establishing a reporting application and database with the Central Data Exchange. The required use of CDX for submission of required data is consistent with the Government Paperwork Elimination Act (GPEA, Pub. L. 105-277), which requires that, when practicable, federal organizations use electronic forms, electronic filings, and electronic signatures to conduct official business with the public. 
Respondents will be required to establish an account in the CDX portal unless they already have done so (e.g., CDR and TRI reporters). Respondents new to CDX will need to create an account profile. To register in CDX, the CDX registrant (also referred to as "Electronic Signature Holder" or "Public/Private Key Holder") downloads two forms: the Electronic Signature Agreement and the Verification of Company Authorizing Official form. Registration enables CDX to perform two important functions: authentication of identity and verification of authorization. Within the "Electronic Signature Agreement" form, the Authorized Official (AO) agrees to certain CDX security conditions. On the "Verification of Company Authorizing Official" form, the AO designates himself/herself as the AO and attests to the completeness and accuracy of the submitted information. When these forms are received, EPA activates the submitter's registration in CDX and sends him or her an e-mail notification. Companies that already have CDX accounts will simply need to log-in and select the mercury inventory application from a menu of options to add the reporting tool to the company CDX profile (see attachment 1.).
EPA believes the adoption of electronic communications may reduce the reporting burden on industry by reducing both the cost and the time required to review, edit and transmit data to the Agency. All information sent via CDX is transmitted securely to protect CBI. Furthermore, if any information in the submission has been claimed CBI, a sanitized copy of the notice must be provided by the submitter. With electronic reporting, this can be done automatically during the submission process, eliminating the need for the submitter to do this manually. Electronic reporting also allows submitters to share a draft notice within their company and save a copy of the final file for future use. 
The Agency also benefits from receiving electronic submissions. Respondents directly enter data into the mercury inventory application online rather than send data to the Agency, which would then be responsible for manually entering data into a system on behalf of the respondents. Electronic reporting reduces potential for data entry errors and reduces the overall cost to the Agency as it limits the need for human resources and provides a more efficient collection of data as well as expedites and simplifies data analysis for the triennial inventory publication. 
	5(c)	Small Entity Flexibility
Approximately 40 percent of the respondents will be small entities. However, small businesses are not exempt from reporting requirements because unlike the exemption for small manufacturers and processors provided under TSCA 8(a)(1)(A) and (B), reporting and recordkeeping requirements associated with TSCA section 8(b) are applicable to all affected entities. EPA is striving to minimize the burden on all respondents, including small entities, as much as possible by developing the reporting application to be user-friendly and dynamic, consisting of straightforward questions that are to include fill-in-the-blank (numbers) fields, check boxes, and drop-down menus. In addition, the Agency is developing support materials tailored to small entities affected by the rule. 
EPA conducted outreach and webinars for small businesses to introduce the reporting database, explain requirements, and offers Q&A and other support. Under TSCA section 26(d), EPA also provides specialized assistance to respondents, particularly to small entities, including technical and other non-financial assistance to manufacturers (including importers) and processors of chemical substances. EPA's TSCA Hotline assists small businesses complying with TSCA rules and provides various materials such as copies of Federal Register notices, advisories, and other information upon request.
	5(d)	Collection Schedule
Persons who must report under the 40 CFR 713are required to submit reports on or before July 1, 2019 and every three years thereafter. The required reporting information applies to the calendar year preceding the year in which the submission deadline occurs (e.g., data for calendar year January 1 to December 31, 2018 submitted on or before July 1, 2019).
ESTIMATING THE BURDEN AND COST OF THE COLLECTION 
This analysis presents the burden and cost estimates for all affected entities over the next  three years is a result of the reporting requirements for manufacturers (including importers) of mercury and mercury-added products and those who otherwise intentionally use mercury in a manufacturing process (i.e. processors) under the authority of Section 8(b) of TSCA. All costs are presented in year 2020 dollars. The information collection assumes reporting at the company level. EPA estimates that a total of 756 manufacturers (including importers) or processors will respond to this information collection, based on numbers of reporters of mercury data to the IMERC Database, as well as the EPA's TRI program and the CDR rule. 
Burden and cost calculations are based on the assumption that each respondent submits one report: Reporting is only required every three years, so there will be one report submitted per respondent during this ICR period. The average burden per respondent per reporting period is estimated to be approximately 69 hours, or 23 hours annually over the three-year period. 
	6(a)	Estimating Respondent Burden
40 CFR 713 requires manufacturers, importers, and processors of mercury and mercury-added products to incur costs associated with compliance determination, rule familiarization, preparation of reports, and recordkeeping.  
40 CFR 713 requires any person who manufactures (including imports) mercury or mercury-added products or otherwise intentionally uses mercury in a manufacturing process to electronically report certain information to EPA, including: volume of mercury manufactured/imported/used, type of mercury-added products manufactured/imported, type of manufacturing processes and function of mercury. The required reporting information may also include the location where mercury is stored and industries into which mercury and mercury-added products are distributed in commerce. 
Four procedural tasks are considered in the estimation of respondent burden. The four respondent activities include: compliance determination; rule familiarization (includes read final rule and reporting requirements/instructions); preparation of reports (includes form completion/submission and CBI claim substantiation); and recordkeeping (includes prepare/submit report and maintain records (partial report) and prepare/submit report and maintain records (full report)). Rule familiarization requires that reporting entities learn the TSCA section 8(b) rule and its various requirements. Entities must then complete an electronic form providing the information listed above. If the submitter claims certain data elements as CBI, they must substantiate the claim by proving certain information supporting the need to keep the information confidential. The fourth task requires reporting businesses to submit information electronically to EPA via CDX, EPA's electronic system for environmental data exchange. Lastly, entities must maintain records of the reported information. Table 1 provides a detailed description of the related Information Collection that corresponds to each activity.
             Table 1: Description of Industry Response Activities
                                   Activity
                                  Description
Compliance Determination
Site staff must determine whether the entity is subject to the rule, based on the identity of chemicals handled at their site and the applicability of certain reporting exemptions. This entails reading the applicability criteria of the rule.

Includes: Read and Understand Applicability Criteria to Determine Whether the Respondent is Subject to the Rule
Rule Familiarization
Site staff must familiarize themselves with the requirements of the rule. This entails reading the rule, understanding the various reporting and administrative requirements, and determining the manner in which the reporting requirements will be met.

Includes: Read Final Rule and Reporting Requirements/Instructions
Preparation of Reports
Site staff must collect all required information regarding mercury production, storage, and/or distribution, including information to substantiate any claims of data confidentiality. Sites are required to submit one form each. The information must be collected and reviewed internally before submission. 

Includes: Form Completion/Submission and CBI Claim Substantiation
Recordkeeping
Respondents must keep records supporting their submissions.

Includes: Prepare/Submit Report and Maintain Records (Partial Report) and Prepare/Submit Report and Maintain Records (Full Report)

Table 2 provides a summary of typical respondent burden for compliance determination, rule familiarization, preparation of reports, and recordkeeping. Certain aspects of electronic reporting are one-time, first-year costs only. Because this ICR covers only one reporting period (information is required every three years), all costs considered are first-year costs. 
Burden to complete the reporting form depends on the type of mercury handled and the company's reporting status to other rules (a reporter is not required to provide certain data if the company already submits that particular information to another reporting program). EPA calculated burden estimates for each element of the collection form based on EPA's Supporting Statement for a Request for OMB Review under the Paperwork Reduction Act: Final Rule Addendum to Partial Update of the TSCA Section 8(b) TSCA Inventory Data Base, Production and Site Reports (EPA ICR No.: 1884.06, OMB Control No 2070-0162) (EPA, 2012), and on EPA's Economic Analysis of the Final Significant New Use Rule for Long-Chain Perfluoroalkyl Carboxylate Chemical Substances and Perfluoroalkyl Sulfonate Chemical Substances (EPA-HQ-OPPT-2013-0225) (EPA, 2014). Industry burden estimate to complete the reporting form is shown in Table 3 for manufacturers (including importers) or processors of elemental mercury, and Table 4 for manufacturers (including importers) or processors of mercury compounds. Table 5 shows the industry burden for manufacturers (including importers) or processors of both elemental mercury and mercury compounds  -  the sum of the activities in both Tables 3 and 4 (without counting compliance determination twice). Based on the total burdens presented in Tables 3 through 5 for the various types of respondents, the reporting burden to complete one form ranges from a low of 44.7 hours for manufacturers (including importers) or processors of elemental mercury who report to CDR, to a high of 111 hours for manufacturers (including importers) or processors of both elemental mercury and mercury compounds who do not report to either CDR or IMERC.

[1] As noted in the economic analysis (EPA 2018), rule familiarization costs are generally only incurred in the first year of the rule, which was covered under the previous ICR. However, due to employee turnover, new employees will also need to become familiar with the rule in order to comply with its requirements. It is assumed that each reporting year, 10 percent of reporters will be replaced by new employees. Therefore, consistent with EPA 2018, the rule familiarization costs shown here are 10 percent of what was presented in the previous ICR supporting statement.

	6(b) Estimating Respondent Cost
To estimate costs, EPA multiplies burden estimates by standard wage rates for attorney, managerial, technical, and clerical levels developed from information published by the Bureau of Labor Statistics (BLS) and a method outlined in the document Wage Rates for Economic Analyses of the Toxics Release Inventory Program (EPA, 2002b). Wage data for managerial, technical, and clerical staff was gathered for manufacturing industries from Employer Costs for Employee Compensation Supplementary Tables: June 2020 (BLS, 2020a). Additionally, wage rates for attorney level were gathered from the BLS Occupational Employment Statistics (OES) May 2019 National Industry-Specific Occupational Employment and Wage Estimates (BLS, 2020b).
The cost of fringe benefits, such as health insurance and vacation, is taken for each labor category from the same ECEC series. Following the outlined methodology (EPA, 2002b), fringe benefits are calculated as a percentage of total wages for each category. Since the fringe benefits for attorney were not available from the BLS report, EPA applied the managerial fringe benefit to wage ratio to this wage as well. EPA added 17 percent to the wages in each category to account for overhead, based on information provided by the chemical industry and chemical industry trade associations in the Revised Economic Analysis for the Amended Inventory Update Rule: Final Report (EPA, 2002a) and Wage Rates for Economic Analyses of the Toxics Release Inventory Program (2002b). The wages for each of the three categories were then multiplied by benefits and overhead factors to estimate loaded, annual salaries in year 2020 dollars. Table 6 contains the loaded wage rates for the managerial, technical and clerical occupation categories.

Table 7 contains the cost per activity of completing a form for one respondent, for each respondent type. To obtain these costs, burden hours presented in Tables 2 through 5 were multiplied by the corresponding loaded wage rate in Table 6. EPA estimates that the total cost for reviewing the rule and completing and submitting one report with recordkeeping ranges between approximately $4,630 and $9,910, depending on the kind of mercury and reporting status. Because the data collection will occur only once during the ICR time period, there are no costs associated with Years 2 and 3.

	6(c)	Estimating Agency Burden and Cost
EPA is responsible for the following activities associated with administering the rule: 
          Industry and public assistance;
          Data processing and systems support; and
          Report preparation, release, and maintenance.
Costs related to EPA activities that involve using the data are not included. EPA has estimated the Agency burden resulting from the new requirements in TSCA for substantiation of CBI claims made as a result of the rule. EPA will further refine these estimates when it revises the cost and estimates for the ICR for 40 CFR part 2 based on the new CBI substantiation requirements.
Agency personnel are responsible for all tasks associated with the rule, and none of the work is estimated to be completed by contractor staff. EPA labor costs are based on annual federal wage rates published by the Office of Personnel Management for the Washington-Baltimore-Northern Virginia, DC-MD-PA-VA-WV Locality Pay Area for 2020 (OPM, 2016). Wages are presented in terms of GS-level and step. Employees at the federal GS-13, Step 5 level will conduct the collection and administrative activities under the rule. A federal GS-14, Step 5 will assist with the review of the CBI claim substantiations. Unloaded wage rates for 2020 for both of these employees are presented in Table 8. Following the methodology outlined in Instructions for Preparing Information Collection Requests (ICRs) (EPA, 1992), EPA added 60 percent to the wage rate to account for fringe benefits and overhead costs. Table 8 derives the loaded wage rates for Agency staff at the GS-13 Step 5 level.

	6(d) 	Estimating the Respondent Universe 
To identify the universe of sites potentially subject to the rule, EPA used three sources: the IMERC database, EPA CDR data, and EPA TRI data.
EPA accessed the IMERC database online (NEWMOA, 2020) and obtained a list of all of the submitter companies within the database. For this analysis, EPA used only the companies contained in the database that provided a submission to IMERC in 2016 (the most recent reporting year at the time this analysis was performed). Among the 2016 submissions, companies that indicated that all of their uses of mercury are now phased out were not included. Therefore, the IMERC database yielded a list of companies with mercury-added products that were not phased out as of 2016. To the extent that some of the companies may have since discontinued the manufacture of mercury-added products, this may be an overestimation of the number of regulated entities. The IMERC database identified 257 relevant companies (considered sites for the purposes of this analysis). The data does not distinguish between elemental mercury-added and mercury compound-added products. EPA assumes that all of the IMERC reports are associated with elemental mercury rather than mercury compounds. 
The most recent reporting year for which CDR information was publicly available at the time this analysis was performed was 2016. The non-confidential 2016 CDR data revealed only five sites manufacturing elemental mercury); two of these sites also reported the manufacture of mercury compounds (mercury chloride and thimerosal).
The most recent reporting year for which TRI information was publicly available at the time this analysis was performed was 2019. For the purpose of this analysis, EPA included TRI reporters of mercury and mercury compounds in the assumed universe of reporters, regardless of their responses as to how the chemical is manufactured, processed, or otherwise used, unless it was indicated that the mercury was manufactured or processed only as an impurity. EPA further excluded reporters not generally known to manufacture mercury or mercury-added products or otherwise intentionally use mercury in a manufacturing process. To the extent that any other reporters may not "intentionally" use mercury, this may be an overestimation of the number of regulated entities. Thus, TRI data for 2019 yielded a total of 160 reports for mercury, and 348 reports for mercury compounds.
Using the combined list of sites reporting to IMERC, CDR, and/or TRI, EPA identified any duplicate site listings by identifying 1) sites with identical TRI Facility ID numbers and 2) sites reporting to both TRI and IMERC or CDR with matching facility names and addresses (there were no sites that reported to both IMERC and CDR). Duplicate sites were excluded. This results in a total of 756 unique sites that are potentially regulated under the rule. The sites were categorized as to whether they handle elemental mercury, mercury compounds or both; and their current reporting status. These results are shown in Table 10.

	6(e)	Bottom-Line Industry Burden and Cost Estimates
This section describes the estimated total social paperwork burden and cost of the section 8(b) rule over its first three years. 
             Respondent Tally
To identify the universe of firms potentially subject to the rule, EPA used three sources: the IMERC database, EPA CDR data, and EPA TRI data. EPA estimated the number of sites in each of the nine categories of reporters (see Table 10), for a total of 756 that would be subject to the rule. Each site is expected to submit one response during each reporting period; there is one reporting period during this ICR period. Table 11 shows the number of responses for the various activities during the first reporting period.

	6(f)	Reasons for Change in Burden
The annual public burden for this collection of information, which is approved under OMB Control No. 2070-0207, is estimated about 23 hours per respondent. This request represents a decrease of 9 hours per respondent from that currently in the OMB inventory, or a total decrease of 20,522 hours (from 72,567 to 52,045 hours), as shown in Table 15. This increase is due to:
 Decrease in rule familiarization burden;
 Decrease in form completion burden due to mercury export prohibitions; and
 Changes in the number of estimated respondents.

In addition, OMB has requested that EPA move towards using the 18-question format for ICR Supporting Statements used by other federal agencies and departments and is based on the submission instructions established by OMB in 1995, replacing the alternate format developed by EPA and OMB prior to 1995. EPA intends to update this Supporting Statement during the comment period to reflect the 18-question format, and has included the questions in attachment 3 to this Supporting Statement. In doing so, the Agency does not expect the change in format to result in substantive changes to the information collection activities or related estimated burden and costs. 
	6(g)	Burden Statement
The annual public burden for this collection of information is estimated to average approximately 23 hours annually per respondent over the three-year period. According to the Paperwork Reduction Act, "burden" means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. For this collection it includes the time needed to review and understand instructions; prepare and submit reports (including searching data sources); complete and review the collection of information; transmit the information; and keep records.
An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control number for this information collection appears above. The OMB control numbers for EPA's regulations in title 40 of the CFR, after appearing in the Federal Register when approved, are listed in 40 CFR Part 9, are displayed either by publication in the Federal Register or by other appropriate means, such as on the related collection instrument or form, if applicable. The display of OMB control numbers in certain EPA regulations is consolidated in 40 CFR Part 9.
To comment on the Agency's need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including the use of automated collection techniques, EPA has established a docket for this ICR under Docket ID No. EPA-HQ-OPPT-2020-0617 which is available for public viewing online at http://regulations.gov.
