                          The Paperwork Reduction Act


1	IDENTIFICATION OF THE INFORMATION COLLECTION

      1(a)	Title of the Information Collection

      Title: 	TSCA Section 4 Test Rules, Enforceable Consent Agreements (ECAs), 
      	Voluntary Testing Agreements (VTAs), Voluntary Data Submissions, and 
      	Exemptions from Testing Requirement

      EPA ICR No.: 1139.11 	OMB Control No.: 2070-0033
      
      Docket ID No.: EPA-HQ-OPPT-2015-0436

      1(b)	Short Characterization/Abstract

      This information collection request (ICR) covers the submission of test data to the Environmental Protection Agency (EPA) to support the decision making process for an industrial chemical under the Toxic Substances Control Act (TSCA) (15 U.S.C. 2601). Under TSCA, EPA has the authority to issue regulations designed to gather health/safety and exposure information on, require testing of, and control exposure to chemical substances and mixtures. Drugs, cosmetics, foods, food additives, pesticides, and nuclear materials are exempt from TSCA. EPA's TSCA Inventory currently contains over 70,000 existing chemicals. The TSCA Inventory is a compilation of the names of all existing chemical substances along with their respective Chemical Abstract Service (CAS) Registry numbers, production/importation volume ranges, and specific sites of production/importation. Chemicals produced in annual volumes above 1 million pounds are considered High Production Volume or "HPV" chemicals. This subset of 3,000-4,000 HPV chemicals is the main focus of OPPT's Existing Chemicals Data Collection and Data Development (Testing) activities. Data on chemicals that are collected or developed are made accessible to the public and are intended to provide input for efforts to evaluate potential risk from exposures to these chemicals.

      As stated in section 2 of TSCA, "It is the policy of the United States that adequate data should be developed with respect to the effect of chemical substances and mixtures on health and the environment and development of such data be the responsibility of those who manufacture and those who process such chemicals and mixtures."

      Section 4 of TSCA gives EPA the authority to require chemical manufacturers and processors to test existing chemicals. Under section 4, EPA can by rule require testing after finding that (1) a chemical may present an unreasonable risk of injury to human health or the environment, and/or the chemical is produced in substantial quantities that could result in significant or substantial human or environmental exposure, (2) the available data to evaluate the chemical are inadequate, and (3) testing is needed to develop the needed data.
      The information collected under this ICR is designed to provide EPA with the necessary data on health effects, ecological effects and environmental fate to predict the probable impacts on human health or the environment of chemicals that may present an unreasonable risk. EPA uses the information collected to assess risks associated with the manufacture, processing, distribution, use or disposal of a chemical, and to support any necessary regulatory action with respect to that chemical.
      
      The Chemical Testing Program in EPA's Office of Pollution Prevention and Toxics (OPPT) also works with members of the U.S. chemical industry and other interested parties to develop needed data via TSCA section 4 enforceable consent agreements (ECAs) and voluntary testing agreements (VTAs). ECAs and VTAs are usually less burdensome than formal TSCA rulemaking and allow EPA to consider agreed-upon pollution prevention and other types of product stewardship initiatives by the chemical industry as a possible substitute for or adjunct to certain types of needed testing. 
      
      The Chemical Testing Program requires the development of test data that provide critical information on health effects, ecological effects and environmental fate that enables EPA and others to properly assess and manage health and environmental risks that may be posed by existing and new chemicals covered by TSCA. The "universe" of existing chemicals on the TSCA Chemical Substances Inventory that may present the greatest potential health and/or environmental concerns have been and continue to be identified and refined through various existing chemical screening activities within OPPT. EPA also makes the testing data publicly available to help the public understand the risks posed by exposure to chemicals and to facilitate the public's involvement in environmental decision-making. (For more information about the Chemical Testing program, go to: https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/data-development-and-information-collection-assess-risks.)
      
      In addition to developing test rules under TSCA section 4 that meet specific needs identified by OPPT, EPA may also develop such actions to meet the information needs of other offices within EPA and other agencies. For example, test data in the past have been developed for EPA's Office of Solid Waste and Emergency Response (OSWER), Office of Air and Radiation (OAR), and Office of Water (OW). EPA has also developed test rules to collect data that would also be used by other agencies, including the Occupational Safety and Health Administration (OSHA), the Agency for Toxic Substances and Disease Registry (ATSDR), and the Organization for Economic Cooperation and Development (OECD), to name a few.
      
      OPPT may also be required to develop a test rule under TSCA section 4 in response to a recommendation received from the TSCA Interagency Testing Committee (ITC). TSCA established the ITC as an independent advisory committee to identify chemicals regulated by TSCA for which there are suspicions of toxicity or exposure and for which there are few, if any, ecological effects, environmental fate or health effects testing data. When the ITC designates chemicals for testing, EPA is required under TSCA section 4(e)(1)(B) to publish Federal Register notices either to initiate proceeding under TSCA section 4(a) or to provide reasons for not doing so. 
      
      In general, when the need for data is identified by EPA, EPA may obtain the needed test data (1) by issuing a test rule through notice and comment rulemaking, (2) through negotiation with industry and issuing an ECA, or (3) through commitments from industry as VTAs.
      
      The testing specified in a rule or ECA issued under TSCA section 4 only needs to be conducted once for each specified chemical. As such, only one of the entities that manufacture, import or process the specified chemical, or a consortia formed by these entities, will conduct the specified testing and report the results of that testing to EPA. An entity subject to a test rule may also apply for an exemption from the testing requirement if that testing will be or has been performed by another party.
      
      Responses to the collection of information specified in a rule issued under TSCA section 4 are mandatory (see 40 CFR part 790, Attachment 2), while responses to an ECA entered into under TSCA section 4 is only mandatory for participants in the ECA. In contrast, participating in a VTA, or otherwise submitting data without a requirement, is completely voluntary. 
      
      The export notification provisions of TSCA section 12 apply to any exporter of a chemical subject to a rule or an ECA issued under TSCA section 4, regardless of their participation in the ECA or any related testing consortia.
      
      Respondents may claim all or part of a document confidential. EPA will disclose information that is covered by a claim of confidentiality only to the extent permitted by, and in accordance with, the procedures in TSCA section 14 and 40 CFR part 2.
      
      EPA maintains an official record for all activities conducted under TSCA section 4 (rulemakings, ECAs, and VTAs). The official record consists of the documents referenced in a specific activity, any public comments received during an applicable comment period, any test data developed (including letters of intent to conduct testing, exemption letters, study plans, progress reports and the final study report), and other information related to the activity, including information claimed as CBI. The official record includes the documents that are physically located in the docket, as well as the documents that are referenced in those documents. The public version of the official record, which includes printed, paper versions of any electronic comments submitted during an applicable comment period, is available for inspection in the Office of Pollution Prevention and Toxics (OPPT) Docket, EPA Docket Center (EPA/DC), EPA West, Room 3334, 1301 Constitution Ave., NW, Washington, D.C. The Public Reading Room is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal holidays.


2	NEED FOR AND USE OF THE COLLECTION

      2(a)	Need/Authority for the Collection

            TSCA section 2(b)(1) states that it is the policy of the United States that "adequate data should be developed with respect to the effect of chemical substances and mixtures on health and the environment and that the development of such data should be the responsibility of those who manufacture [which is defined by statute to include import] and those who process such chemical substances and mixtures."

      To implement this policy, TSCA section 4(a)(1) mandates that EPA require manufacturers and processors of chemical substances and mixtures to conduct testing if it finds that:
      
            "(A)(i) the manufacture, distribution in commerce, processing, use, or disposal of a chemical substance or mixture, or that any combination of such activities, may present an unreasonable risk of injury to health or the environment,
            (ii) there are insufficient data and experience upon which the effects of such manufacture, distribution in commerce, processing, use, or disposal of such substance or mixture or of any combination of such activities on health or the environment can reasonably be determined or predicted, and (iii) testing of such substance or mixture with respect to such effects is necessary to develop such data; or

            (B)(i) a chemical substance or mixture is or will be produced in substantial quantities, and (I) it enters or may reasonably be anticipated to enter the environment in substantial quantities or (II) there is or may be significant or substantial human exposure to such substance or mixture,

            (ii) there are insufficient data and experience upon which the effects of the manufacture, distribution in commerce, processing, use, or disposal of such substance or mixture or any combination of such activities on health or the environment can reasonably be determined or predicted, and

            (iii) testing of such substance or mixture with respect to such effects is necessary to develop such data [.]"

      If EPA makes these findings for a chemical substance or mixture, the Agency must require that testing be conducted on that chemical substance or mixture. The purpose of the testing would be to develop data about the substance or mixture's health and environmental effects where there is an insufficiency of data and experience in order to support a determination that the manufacture, distribution in commerce, processing, use or disposal of the substance or mixture, or any combination of such activities, does or does not present an unreasonable risk of injury to health or the environment.

      Once the Agency has made a finding under TSCA section 4(a)(1), EPA may require any type of health or environmental effects testing necessary to address unanswered questions about the effects of the chemical substance. EPA need not limit the scope of testing required to the factual basis for the TSCA section 4(a)(1)(A)(i) or (B)(i) findings, as long as EPA finds that there are insufficient data and experience upon which the effects of the manufacture, distribution in commerce, processing, use, or disposal of such substance or mixture or of any combination of such activities on health or the environment can reasonably be determined or predicted, and that testing is necessary to develop the data. This approach is explained in more detail in EPA's statement of policy for making findings under TSCA section 4(a)(1)(B) (a.k.a. the "B" policy) in the Federal Register of May 14, 1993 (58 FR 28736, 28738-39; FRL-4059-9).

      The statute also specifies that EPA should give priority consideration to chemicals that the TSCA ITC places on the TSCA section 4(e) "Priority Testing List." The ITC is an independent advisory committee to the EPA Administrator that includes 14 U.S. Government organizations. The ITC was created under TSCA section 4(e) to: 1) review chemicals regulated by TSCA, 2) determine which chemicals need ecological effects, environmental fate or health effects test data and 3) add those chemicals with test data needs to the Priority Testing List and recommend them for testing or information reporting in May and November Reports to the EPA Administrator. (For more information about the ITC, see: https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/interagency-testing-committee.)

      Although the Agency may not have yet made the TSCA section 4(a) finding for a particular chemical substance, EPA may still cooperate with industry or others to identify data gaps and develop testing plans to fill some or all of these gaps. These voluntary efforts help provide additional information about the many chemicals on the TSCA Inventory, and can be used to assess the potential risks associated with the manufacture, processing, distribution, use or disposal of the chemical, as well as allowing the Agency to establish a regulatory agenda that focuses on those chemicals of greater concern.

      The information collected through the Chemical Testing Program, whether submitted pursuant to a rule or ECA or voluntarily, provides critical information on health effects, ecological effects and environmental fate that enables EPA and others to properly assess and manage health and environmental risks that may be posed by existing and new chemicals covered by TSCA. This information is also made publicly available to help the public understand the risks posed by exposure to chemicals and to facilitate the public's involvement in environmental decision-making.
      
      2(c)	Practical Utility/Users of the Data

      Data collected under the Chemical Testing Program are used, in conjunction with exposure information, by EPA scientists to determine whether the subject chemicals are likely to present an unreasonable risk to human health or the environment. Furthermore, such information, considered in conjunction with toxicological and health effects data, ecological effects data, and environmental fate data, will be used by non-EPA scientists, professional industrial hygienists, other occupational health professionals and workers for hazard communication and right-to-know purposes, including Safety Data Sheets (SDSs) and product labels required under OSHA regulations.

      Additionally, data developed for chemicals used or produced in particular work sites will be useful in developing and/or maintaining comprehensive safety and health programs at those facilities. Local, state and county governments rely on the Agency's ability to set health and environmental standards, as do other national governments. The paperwork related requirements imposed on the respondents as part of the Chemical Testing Program allow EPA to ensure that the necessary testing data will be developed, that the results meet basic scientific standards of acceptability and adequacy, that unforeseen complications or issues can be addressed, and that the testing is progressing on schedule.

      If the test data submitted indicate that potentially unreasonable risks may exist, the data will be used by EPA and the manufacturer to determine the appropriate action necessary to avoid or mitigate the risks. To date, EPA has used collected data to perform the necessary assessments that support such activities as the development of water quality criteria, hazardous waste listings, chemical advisories, and reduction of workplace exposures. EPA has also used the resulting assessments to identify chemicals that may not warrant additional regulation or concern, or should otherwise be treated as a low priority for further consideration.

      In addition, since EPA is required under TSCA section 4(d) of TSCA to publish a Federal Register notice announcing the receipt of test data developed under a TSCA section 4 rule, the data collected may be used by other agencies and interested parties.

      Since 1979, approximately 230 of the 15,000 chemicals on the TSCA Inventory that are, or have been, produced in quantities greater than 10,000 pounds per year have been the subject of testing actions within the OPPT Existing Chemicals Testing Program. Virtually all of the 230 chemicals are "High Production Volume (HPV) chemicals." The testing actions taken to date include a mix of formal TSCA section 4 Test Rules and ECAs. In addition, almost 250 formal TSCA section 4 "Decisions Not to Test" (DNTs) have been issued by EPA to date. EPA maintains a listing on its website that identifies the TSCA chemicals for which testing data has been received by EPA under TSCA section 4, along with basic background information about the chemical, and available summaries of the testing results.


3.	NON-DUPLICATION, CONSULTATIONS, AND OTHER COLLECTION 
	CRITERIA

      3(a)	Non-Duplication

      In general, the activities associated with collecting test data for chemicals regulated under TSCA is not duplicated by any other Agency or office within EPA. TSCA is the only applicable authority to allow for such data collection, and TSCA specifically assigns that authority to EPA. In addition, EPA takes several steps to ensure that its requests for data do not result in duplicative efforts by those responding:

      ::	A single submission of the data will satisfy the request.
      ::	Prior to proposing a test rule or entering into an ECA, EPA searches the scientific literature, holds public information gathering meetings if deemed appropriate, and has discussions with industry representatives in order to determine what types of data have already been obtained about the chemical under consideration. The Agency proposes a test rule or enters into an ECA only after it has determined that necessary tests have not yet been conducted. 
      ::	Exemption applicants are not required to supply information that the Agency can obtain by other existing processes. The equivalence information required provides verification that a chemical is the same. Often this information is CBI and only the manufacturer or processor of the chemical has this information.

      3(b)	Public Notice Required Prior to ICR Submission to OMB

      In proposing to renew this ICR, EPA provided a 60-day public notice and comment period that ended on May 16, 2016 (81 FR 13790, March 15, 2016). EPA received one comment, from the American Chemistry Council, during the comment period. A copy of the comment and of EPA's response to the comment are included as Attachments 4 and 5, respectively.
      
      3(c)	Consultations

      Additionally, under 5 CFR 1320.8(d)(1), OMB requires agencies to consult with potential ICR respondents and data users about specific aspects of ICRs before submitting an ICR to OMB for review and approval. In accordance with this regulation, EPA submitted questions to nine parties via e-mail. The individuals contacted were:
      Scott Jensen
      Chemical Safety, TSCA, etc.

      eheyd@nrdc.org

      EPA did not receive any direct responses to its solicitation for consultations. The ACC, however, did submit a comment to the docket during the public comment period described in the preceding section. A copy of EPA's consultation e-mail to the above potential respondents is included in Attachment 6.
      
      3(d)	Effects of Less Frequent Collection

      Test rules and ECAs require the test sponsor to submit to EPA a letter that identifies who will be conducting the testing, study plans before beginning testing, and a final report that contains the study results. Each exemption applicant is required to submit an exemption application to EPA. In either case, each submission is intended to be a one-time submission to EPA. Less frequent collection would equate to no collection and could jeopardize EPA's ability to ensure that testing is being conducted in accordance with the rules and ECAs, and to grant timely exemptions from test rules.

      3(e)	General Guidelines under the PRA

      The data retention requirements for test rules and ECAs exceed one of the PRA guidelines contained in 5 CFR 1320.6. Documentation records, raw data, and specimens pertaining to a test rule or ECA study are required to be retained for ten years from the effective date of the applicable test rule or publication date of the ECA. These recordkeeping requirements are codified in 40 CFR 792.195. This requirement is necessary to permit sufficient time to review results, perform appropriate risk assessments and, when necessary, to institute appropriate regulatory control responses. Long-term studies may take five years from the effective date of the final test rule or ECA to perform and submit to the Agency; assessment of study results may require an additional one to two years of internal and external peer review; institution of regulatory controls and legal challenges may require an additional two to three years before final resolution of issues. All studies, both short and long-term, are relevant to assessing the potential risk of the chemical and therefore must be retained during the ten year period. In those regulatory cases where either the Agency's action or the data upon which it is based are challenged, it is imperative that all records, raw data, and specimens be available for further review or investigation.

      3(f)	Confidentiality

      Information submitted to EPA in response to test rules and ECAs and in exemption applications is, in most cases, non-confidential. If respondents wish to claim information submitted in response to a test rule or ECA to be confidential, they may do so. These claims will be handled according to the EPA procedures described in 40 CFR part 2 and the TSCA Confidential Business Information Security Manual, which call for careful protection of confidential business information.
      
      3(g)	Sensitive Questions

      No information of a sensitive or private nature is requested in conjunction with this information collection activity, and this information collection activity complies with the provisions of the Privacy Act of 1974 and OMB Circular A-108.

      3(h)	Electronic Submissions

      On December 4, 2013, EPA finalized a rule to require electronic reporting of certain information submitted to the Agency under TSCA sections 4, 5, 8(a) and 8(d). The rule became effective in March 2014. Submitters are now required to use EPA's Central Data Exchange (CDX), the Agency's electronic reporting site to make submissions in response to TSCA section 4, including test rules and ECAs. Submitters must register to use EPA's Agency-wide CDX portal for submitting information in a secure manner, select the Chemical Safety and Pesticide Programs (CSPP) portion of the site, access a Web-based TSCA reporting tool called the Chemical Information Submission System (CISS), and select the TSCA section 4 option for submitting test rule and ECA data. (Note: Users who have previously registered with CDX are able to add "Submission for Chemical Safety and Pesticide Program (CSPP)" to their current registration.) This reporting tool is compatible with Windows, Mac, Linux, and UNIX based computers, and uses "Extensible Markup Language" (XML) specifications for efficient data transmission across the Internet. Two test rules that were issued before the electronic reporting rule went into effect in March 2014 are still active. Submissions for these two test rules have been made by using the U.S. Mail and by the new requirement of electronic submission. Any new test rules will be made by electronic submission alone.


4	THE RESPONDENTS AND THE INFORMATION REQUESTED

      4(b)	Information Requested
      
      4(b)(i)	Data Items
      
      EPA may require any type of health effects, ecological effects and environmental fate testing necessary to address unanswered questions about the effects of a chemical substance. EPA need not limit the scope of testing required to the factual basis for the TSCA section 4(a)(1)(A)(i) or (B)(i) findings, as long as EPA also finds that there are insufficient data and experience upon which the effects of the manufacture, distribution in commerce, processing, use, or disposal of such substance or mixture or of any combination of such activities on health or the environment can reasonably be determined or predicted, and that testing is necessary to develop such data. This approach is explained in more detail in EPA's statement of policy for making findings under TSCA section 4(a)(1)(B) (frequently described as the "B" policy) in the Federal Register of May 14, 1993 (58 FR 28736, 28738-39; FRL-4059-9).

      In addition to submitting the specified test data to EPA, respondents may also need to submit a letter of intent, study plans and progress reports, or an exemption application. Respondents must also maintain certain records related to the testing.

      The specific requirements and procedures governing testing ECAs, test rules, and exemption from test rules are found in 40 CFR part 790. The requirements regarding Good Laboratory Practice standards (GLPs) are found in 40 CFR part 792, the various test guidelines that are incorporated into the individual test rules are in 40 CFR parts 795 through 799, and the chemical specific testing requirements are in 40 CFR part 799.

      The following is an overview of the specific requirements for each type of activity:

      Test Rules  -  EPA may promulgate a rule describing what type of testing must be performed on the chemical and specifying specific test guidelines that have been published by the EPA or alternative methods proposed by industry and approved by EPA as test methods. In combination with the GLPs requirements, these guidelines or methods provide the TSCA-mandated standards (TSCA section 4(d)) for development of adequate and reliable data. Records concerning data developed according to these standards must be retained for a minimum of ten years, as described in GLP standards. Information collections under TSCA section 4(c) are designed to reduce the burden of duplicative testing under test rules. As such, test rules generally require testing of only a single representative chemical substance and all chemicals subject to the test rule are assumed to be equivalent to it.

      Testing Agreements: ECAs and VTAs  -  EPA may negotiate an ECA or VTA under which manufacturers agree to conduct specific testing and submit the data to EPA. The ECA or VTA describes what type of testing is to be performed on the chemical and which test guidelines need to be followed to generate the data sought. Although EPA is wrapping up the HPV Challenge Program that was covered in previous ICRs and employed the use of VTAs, EPA may still enter into individual VTAs in the future.

      As with test rules, the test guidelines have either been published by EPA or another organization (e.g., OECD), or involve alternative methods proposed by industry and approved by EPA as test methods. In combination with the GLPs requirements, these guidelines or methods provide the TSCA-mandated standards (TSCA section 4(d)) for development of adequate and reliable data. Records concerning data developed according to these standards must be retained for a minimum of ten years, as described in GLP standards. Information collections under TSCA section 4(c) are designed to reduce the burden of duplicative testing under test rules. As such, test rules and ECAs generally require testing of only a single representative chemical substance and all chemicals subject to the ECA or VTA are assumed to be equivalent to it.

      Testing Exemption Applications  -  TSCA section 4 allows an entity subject to a test rule to apply for an exemption from the testing requirement if that testing will be, or has been, conducted by another party. Any manufacturer or processor subject to a test rule may submit an application to EPA for an exemption from performing any or all of the tests required under the test rule. The exemption application process and requirements are set out in 40 CFR Part 790, Subpart E. The exemption application, which generally must be filed within thirty days after the effective date of the test rule, must identify the test rule, the chemical, and the Chemical Abstract Service Registration Number (CASRN) of the test substance on which the application is based, and the specific testing requirement(s) from which an exemption is sought, along with the basis for the exemption request. An exemption application will generally be approved if a letter of intent to conduct the testing has been received from another party; if a study plan submitted by another party has been approved; or if the data needs identified in the test rule have been satisfied by another party. A procedure is provided for the appeal and hearing of the denial of an exemption application. Exemptions are also only relevant for testing requirements in test rules.

      Voluntary Data Submissions  -  Unrelated to any test rule or other testing requirement or agreement, chemical manufacturers may voluntarily submit data to EPA at any time. Should they decide to do so, EPA simply asks that they follow the same procedures for preparing their package and completing their submission. Since such data submissions are entirely voluntary and based on decisions in which EPA is not a participant, EPA can only provide a general estimate of potential burden and costs associated with such submissions, guided generally by past such submissions, which have been rare. In doing so, EPA believes that the potential costs and burdens for such voluntary submissions are captured in this information collection request. 

      4(b)(ii)		Respondent Activities

       (1)	Electronic Submission Activities
      
	Prior to transmitting TSCA section 4 reports and other key correspondence, new submitters must register with CDX. In addition, these respondents must complete an Electronic Signature Agreement form, including signature and date, and then submit the form electronically back to EPA.

       (2)	Document Preparation Activities
      
      Respondents may undertake one or more of the following activities:

      (a)	Review rulemaking  and/or participate in ECA or VTA discussions.
      (b)	Conduct searches for relevant existing data. If data are found:
      i.	Determine whether the data are relevant;
      ii.	Prepare and review summary of existing data; and
      iii.	Submit summary of existing data to EPA.
      (c)	Submit "Letter of Intent" to EPA.
      (d)	Plan necessary activities, e.g., consortia, arrange for conduct of studies, etc.
      (e)	Prepare and submit periodic progress reports.
      (f)	Record and prepare test data for submission (includes QA/QC reviews).
      (g)	Prepare and review final report.
      (h)	Review submission for CBI.
      (i)	Submit final report with test data to EPA.
      (j)	Maintain test data and final report in records.
      (k)	Complete and submit testing exemption application, when applicable 

      These activities may vary based on the category under which the activity may occur:

      Test Rules  -  Test rules require manufacturers/importers of the subject chemical substance to submit a letter identifying who is sponsoring the required testing and study plans before testing begins, semi-annual progress reports, as applicable, during the conduct of the testing, and a final report of the test results. Since data are typically required on a chemical basis  -  as opposed to a manufacturer basis  -  test sponsors typically join forces to satisfy the testing requirements.
      Testing Agreements: ECAs and VTAs  -  Signatories to an ECA or VTA commit to provide data for the subject chemical substance, and typically adopt the same approach as that used for test rules. As such, one of the participants would take the lead to submit a letter identifying who is sponsoring the required testing and study plans before testing begins, semi-annual progress reports during the conduct of the testing, and a final report of the test results.

      Voluntary Submissions  -  This activity is not prompted by any rule or agreement. As a result, it only involves the submission of a test final reports and a Robust Summary of the test results.

      Testing Exemption Applications  -  If an entity determines that they are subject to a testing requirement, but qualify for an exemption, they would submit a completed exemption application to EPA that requested the exemption and provided an appropriate rationale. Exemption applicants are not required to supply information that the Agency can obtain by other existing processes. Equivalence data are often confidential business information (CBI) and only the manufacturer or processor of the chemical has this information. In general, test rules reduces the burden associated with preparing exemption applications to a minimum by restricting the information required to that absolutely necessary to determine if the applicant is eligible for an exemption. In most cases, the manufacturer is required to give only its identity, address, a technical contact and a list of the tests for which an exemption is being requested. When equivalence data are needed because more than one representative substance is being tested, the Agency will limit the data required by giving minimum chemical specific requirements in the individual test rules. This approach was devised in response to comments by industry that applying the broad equivalence data requirements to all exemptions candidates would, in some cases, result in submission of unnecessary data.

      Exemption applications are not necessary for chemicals being tested under an ECA or VTA because of the inherent nature of the related agreement process itself. For the same reason, an exemption application would not be submitted by someone who is voluntarily submitting data, because an exemption is never necessary when there is no requirement.


5	THE INFORMATION COLLECTION - AGENCY ACTIVITIES, COLLECTION
      METHODOLOGY, AND INFORMATION MANAGEMENT

      5(a)	Agency Activities

      Data submitted under TSCA section 4 test rules, ECAs, or voluntarily agreement are received by OPPT, Chemical Control Division (CCD), Chemical Information and Testing Branch (CITB), where they are reviewed for completeness and then routed to biologists, chemists, toxicologists, and wildlife scientists within OPPT to determine whether the subject chemicals are likely to present an unreasonable risk to human health or the environment. If the data indicate that potential hazards may exist, then these data  -  coupled with exposure and use information received under the Chemical Information Reporting rule (CDR) and other information sources  -  will be reviewed by EPA staff. Once reviewed, these data may support possible risk management action. To date, EPA has collected data that have been used to support such activities as the development of water quality criteria, hazardous waste listings, chemical advisories, and reduction of workplace exposures.

      For the TSCA Chemical Testing Program covered by this ICR, EPA must undertake the following activities:

      a)	Review letters of intent and study plans for completeness;
      b)	Review progress reports;
      c)	Review final reports for completeness, accuracy, adherence to test rule guidelines and GLPs;
      d)	Process and review exemption applications; and
      e)	Facilitate development of test rules, ECAs and VTAs, as appropriate.

      Related to the activities cited in (c) above, the Agency maintains a facility inspection and test data audit program to ensure testing is done in compliance with GLPs. EPA  may also participate in other activities related to the TSCA Chemical Testing Program, e.g., other voluntary efforts to identify data needs and develop that test data, efforts to establish test guidelines or standards that may be used in the TSCA Chemical Testing Program, and international efforts related to chemical testing and associated testing issues.

      5(b)	Collection Methodology and Management
      
      For each chemical identified for testing within EPA's TSCA Chemical Testing Program, the specific data requested, the testing necessary to generate those data, along with the test protocols, the time frame for completing the testing, and the date by which the requested data are to be submitted to the Agency, are established in the TSCA section 4 Test Rule, ECA or VTA. 

      Test data submitted to the Agency under the TSCA Chemical Testing Program are reviewed by scientists to determine whether or not the data developed are adequate for the purposes for which they were gathered and to determine whether or not further regulatory action is necessary. In addition to being housed in an appropriate EPA TSCA docket, references to the data are entered into the TSCA Test Submission Database (TSCATS). TSCATS is a publicly available, online index to unpublished, non-confidential studies covering chemical testing results and other submitted studies on the possible effects of chemicals on health and ecological systems. Submitted studies are indexed in TSCATS under three broad categories: health effects, ecological effects and environmental fate. TSCATS contains information that is pertinent to risk assessment and hazard evaluation processes. The information can be used in conjunction with published material and is a valuable source along with or in the absence of published data. The data are used by federal and state agencies, researchers, toxicologists, risk assessors, the regulated industry, attorneys, trade and professional associations as well as the public at large.
TSCATS was developed by EPA in 1985 to make the results of ongoing and completed chemical testing available to the public and includes chemical exposure studies, epidemiology, environmental fate, monitoring, episodic incidents, such as spills and case reports. 

      There are four primary types of documents referenced in the TSCATS database: TSCA section 4 chemical testing results, TSCA section 8(d) health and safety studies, TSCA section 8(e) substantial risk of injury to health or the environment notices, and voluntary documents submitted to EPA known as For Your Information (FYI) submissions. TSCATS is available through a number of electronic sources; the studies referenced in TSCATS can be viewed in EPA's public TSCA docket located at EPA's Headquarters in Washington, D.C., or, alternatively, via microfiche copies that are available through the National Technical Information Service (NTIS).
      
      5(c)	Small Entity Flexibility

      The test rule process minimizes the burden on small businesses by giving them the option of fulfilling their responsibilities under a test rule by either joining a testing consortium or by applying for a test rule exemption. Participation in a testing consortium relieves the small business of direct responsibility for collecting or submitting test information as well as applying for an exemption.

      Under ECAs, small businesses are not required to participate, but if they do, they would participate as part of a consortium.

      Small businesses are also apportioned a smaller proportion of the cost of testing than their larger counterparts. The decision as to how the cost of testing is to be divided among these firms has, to date, been decided by the manufacturers subject to the rule or ECA. Generally, small businesses are assigned a proportion of the costs that is proportionate to their size and market share. However, if any party believes a particular reimbursement arrangement is unfair, TSCA directs the Administrator of EPA to assist in resolving the conflict and the Agency will certainly consider the special needs of small businesses if such action becomes necessary. To date, no party has requested that the Agency assist in reimbursement decisions.

      5(d)	Collection Schedule

      This information collection activity does not have a calendar-based schedule. The testing period is defined by the individual test rule, ECA, or VTA. The time required to conduct the test, based on testing guidelines, is in accord with the timeline established in the approved test plan, or timing otherwise established by the Agency. Required testing is conducted only once, and each related activity occurs on a one-time basis. For the reasons described above, the collection is considered an "on occasion" collection. Also note that in this ICR renewal, the definition of a response (i.e., submission) is changed to include all testing activities associated with a chemical. As in previous ICRs, the time period for screening level testing is usually less than a year. The typical time period for other types of testing is around three years, although it can be longer and varies according to the chemical and the test required. See Section 6(a) for revised methodology and Table 3 for a summary of typical activities per chemical over a three year period, and on average annually.



6	ESTIMATING THE BURDEN AND COST OF THE COLLECTION

      6(a)	Methodology and Assumptions

	The methodology used to estimate the annual burden and costs to industry resulting from TSCA section 4 test rules, testing agreements, exemption applications, and voluntary submissions over the next three years has been revised starting with this ICR renewal. Two key changes are implemented. First, the response definition is changed from "per-activity" to a "per-chemical" metric. A response is now defined as the collection of activities pertaining to the "standard" testing battery of ten tests (seven short-term; three long-term), all of which are performed on one specified chemical. This response definition provides the necessary structure for accurate and transparent scaling according to conditions for "number of chemicals" (e.g., involved in a test rule).   Second, for test rules and testing agreements, the annual rate for activities is rigorously calculated (i.e., prorated) to accurately reflect the assumption that long-term studies are three years in duration.  The resultant unit burdens are in units of annual responses per chemical and are readily used with revisions to conditions for test rules, testing agreements, voluntary submissions, and exemption applications. Additionally, electronic reporting was implemented during the previous ICR period, requiring unit burden and supply cost revisions.

 	The revised unit burden and cost estimates are combined with information on current conditions concerning the number and type (i.e., number of chemicals involved) of TSCA section 4 test rules, testing agreements, and voluntary submissions, all of which may result in industry submitting existing data or conducting new testing to provide EPA with information necessary to evaluate chemicals under its TSCA section 4 mandate. These assumptions are discussed in detail below. For reference, the respondent burdens are organized according to OMB-designated information collection (ICs) as follows:
  
      ::	CDX Registrations for e-Reporting
      ::	Test Rules
      ::	Testing Agreements: ECAs, and VTAs
      ::	Voluntary Submissions
      ::	Testing Exemption Applications
	

      Methodology
      
	Respondent reporting burden and costs are derived herein. In addition to reporting burden, this analysis provides estimates for testing costs. Note that a response is defined as the collection of related activities involving a battery of ten tests (seven short-term, three long-term), all of which pertain to one specified chemical.

       (1)	Reporting Burden and Costs
      
      Reporting burden and costs are based on the following activities: CDX registration, preparing letters of intent and study plans; preparing progress reports; preparing test results in final reports; preparing robust summaries; recording test results; conducting laboratory and/or corporate reviews; and recordkeeping. 

	The burden estimates by activity, and associated supply costs are listed in Table A of Attachment 3. These estimates are based on estimates in the prior ICR, as updated for e-reporting. The wage rate information by type of labor (i.e., managerial, technical, clerical) is presented in Table B of Attachment 3. Detailed calculations provided in Sections 6(b)(i) through 6(b)(v) are based on these tables. The next section presents the estimates for testing burden and costs for use in final summary tables (Section 6(d)(i)). The estimates for reporting burden are presented below in Sections 6(b)(i)-(v) for CDX registration, test rules, testing agreements, voluntary submissions, and testing exemption applications, respectively. 

       (2)	Testing Costs
      
      Testing costs include laboratory costs and administrative costs. For purposes of this ICR, as in past ICRs, EPA assumes that the tests specified in a standard testing battery of ten tests are all likely to be performed on each chemical. As shown in Table 1, seven of these studies are designated as short-term as they are expected to conclude within the year that they are initiated, and three of these studies are designated as long term as they will take three years to conclude. The costs presented in Table 1 are drawn from an EPA-maintained listing of the laboratory cost data for numerous TSCA and OECD test protocols (EPA 2013a). Estimates include non-labor costs for analytical chemistry method development and validation where it was judged that such method development would be necessary to conform to good laboratory practices. Short term and long-term studies are assigned costs based on typical costs cited by industry experts (Piccirillo, 2004). Both labor and non-labor test costs were adjusted to end-of-year 2014 dollars using an employment cost index (ECI via US BLS 2014). The overall cost of the "standard" testing battery (per chemical) is estimated at $1,663,397.

      Testing administrative costs are based on the following activities: organizing the testing program, obtaining and reviewing bids from laboratories, and submitting samples to the laboratory for testing.

      Based on experience, EPA assumes that the administrative costs associated with testing programs total approximately 25 percent of the laboratory costs, with the following components: 
      
      ::	15 percent of the test cost accounts for management of a consortium. This includes activities such as identifying manufacturers, meetings, organizing payment for testing, developing contracts for testing, and employing toxicologists who may be hired to provide technical expertise for the testing.
      
      ::	10 percent of the test cost is used to cover the costs of technical experts. These experts that may work for the consortium and covers study review and site visits to the laboratory. 
      This amounts to a total of 25 percent of the laboratory costs to account for administering the testing consortium and the testing. Applying these assumptions to the total reported laboratory costs of $1,663,397 (as presented in Table 1), yields an estimate of $2,079,246 per chemical for the full extent of the testing assumed to be conducted over three years. Based on conditions reported later is this analysis, the resultant testing costs total $27,030,195 over three years, with the annual cost at $9,010,065 (presented in Table 2).

Notes:
[a] See later sections (e.g. 6(b)(ii) for test rules) for discussion of assumptions regarding conditions for this ICR period.
[b] Administrative non-reporting costs are assumed to equal 25% of laboratory costs.

      6(a)(ii)     Assumptions: Respondents and Activities in the Per-Chemical Response
	
	With the exception of voluntary submissions, electronic submissions are required. Therefore, estimates are made to assess burden and cost for respondents who are setting up first-time e-reporting. Submitters are required to register with CDX and complete the electronic signature agreement.

	For purposes of this ICR, and consistent with most recent information on e-reporting (EPA 2015), EPA assumes that 40% of respondents are new CDX submitters, yielding 8.4 responses annually. These respondents may be from firms that are new to EPA e-reporting or they may be employees new to e-reporting due to turnover within a firm that has prior experience with e-reporting. 

	With respect to test rules and testing agreements, EPA assumes that there will be one test sponsor for each chemical substance subject to testing. In cases where there is more than one manufacturer of the chemical subject to testing, it is assumed that the other manufacturers subject to the request for information will participate in a consortium that is managed by the test sponsor. 

	Based on experience, EPA retains the same assumption that was used in past ICRs. For a specified chemical, each sponsor is expected to submit:
 
      ::	one letter of intent and one set of study plans; 
      ::	five semi-annual progress reports per long-term study; and
      ::	one final report for each long-term and short-term study.

      EPA estimates that 10 percent of the studies completed will be accompanied by a robust summary, yielding one robust summary.

	Table 3 summarizes the activities overall for a three year period and derives the average annual frequency to use in ICR estimates. For test rules, EPA assumes that conditions for the next ICR period will amount to the equivalent levels of burden and cost for two rules per year with each involving five chemicals. For testing agreements, EPA assumes that there will be two agreement per year involving one chemical.

Notes: 
1. Note that a response is defined as the collection of related activities involving a battery of ten tests (seven short-term; three long-term) all of which pertain to one specified chemical. See Table 1 for additional detail.
2. Additional detail is provided in Attachment 3. Table A lists detailed activities and applicable labor categories (i.e., managerial, technical, clerical); Table B provides wage rates.
3. Long-term studies are completed in three years; short-term studies are completed in one year.
4. Averages per year are rounded for presentation purposes but are not rounded for calculations of total burden.
      
      For voluntary submissions, given that the submission is unrelated to any agreement or other testing requirement, the related activities are more generic, involving final reports and the associated recordkeeping. Although the nature and frequency of such submissions cannot be predicted, EPA conservatively assumes, as in previous ICRs, that there will be one submission per year involving one chemical. Although submitters may use e-reporting, at this time there have been no voluntary submissions and therefore no e-reporting is assumed. Also in the same manner as in previous ICRs, each submission includes:

      ::	ten final reports; and
      ::	one robust summary (10%, as discussed above).

	For testing exemption applications, EPA assumes, as in previous ICRs, that two applications per year, each involving one chemical will be submitted. Table 4 summarizes the assumptions on respondents and responses, by type of information collection (IC).

      6(b)	Estimating Respondent Burden and Cost
      
	To mirror the designated information collections (ICs) in the system used for submitting the ICRs to OMB for approval, the burden and cost estimates are grouped as follows:

      ::	CDX Registrations for e-Reporting
      ::	Test Rules
      ::	Testing Agreements: COs, ECAs and VTAs
      ::	Voluntary Submissions
      ::	Testing Exemption Applications

      The burden and cost estimates, unit labor costs, and unit supply costs are listed according to detailed activity in Table A of Attachment 3. The wage rate information by type of labor (i.e., managerial, technical, clerical) is provided in Table B of Attachment 3. Detailed calculations that are presented in Sections 6(b)(i) through 6(b)(v) draw information from these tables.
      
      6(b)(i)  CDX Registration for e-Reporting

	As a result of the final electronic reporting rule of 2013, and as of March 2014, respondents incur a small amount of additional burden and costs in carrying out the additional activities associated with e-reporting. Activities that are needed to facilitate electronic submission include: CDX registration and CDX electronic signature. Table A in Attachment 3 provides unit burden and cost estimates based on the most recent on e-reporting information as reported in the Section 5 ICR renewal supporting statement (EPA 2015). For purposes of this ICR, EPA assumes that 8.4 new submitters register annually for purposes of TSCA section 4 e-reporting. These respondents may be from firms that are new to EPA e-reporting or they may be employees new to e-reporting due to turnover within a firm that has prior experience with e-reporting. Table 5 presents unit and total burdens and costs. The information presented in Table 5 is used to complete the IC entry for this group of collection activities under this ICR, as shown in Table 6.

      6(b)(ii)		Test Rules
      
	In this ICR TSCA section 4 test rule activity is anticipated from rules promulgated prior to this ICR period. Such test rules are still generating responses from sponsors because testing projects can have protracted timelines and/or can encounter delays. Additionally, potential new rules promulgated in the next three years are considered as part of this ICR's scope. For purposes of estimates for this ICR period, EPA assumes that both effects amount to the equivalent activity of issuing two rules annually with five chemicals per rule. Activities are as described in Section 6(a)(ii), plus recordkeeping. Each chemical is evaluated by performing the tests specified in the "standard" testing battery with seven short-term and three long-term tests, as portrayed in Table 1. The list of activities is the same for test rules and testing agreements with annual frequencies drawn from Table 3. Activity-level and per-chemical unit burdens reflect updates due to e-reporting (see Tables A and D in Attachment 3 for reference).

       (1)	Estimated Annual Respondent Burdens and Costs  -  Test Rules
      
	This section presents test rules unit burdens and costs, followed by total burden and cost. Table 7 presents components of unit burdens and unit costs for test rules (note these are the same for test rules and testing agreements). Given the unit values from Table 7, and applying the conditions of two rules per year and five chemicals per rule, yields total burden and cost results presented in Table 8.

      6(b)(iii)	Testing Agreements: Enforceable Consent Agreements (ECAs) and 
      		Voluntary Testing Agreements (VTAs)

	The specific testing required under future ECAs/VTAs cannot be predicted at this time because it is determined on a case-by-case basis. EPA assumes, as in previous ICRs, that there will be two agreements per year, each involving one chemical. Activities are as described in Section 6(a)(ii), including recordkeeping. Each chemical is evaluated by performing the tests specified in the "standard" testing battery in Table 1. The test battery includes 10 studies per chemical (7 short-term, 3 long-term). The list of activities is the same for test rules and testing agreements with annual frequencies drawn from Table 3. 

       (1)	Estimated Annual Respondent Burdens and Costs  -  Testing Agreements

	This section presents testing agreement total burden and cost (see Table 7 for components of unit burdens and unit costs). Given the unit values from Table 7, and applying the conditions of two testing agreements per year and one chemicals per agreement yields total burden and cost results presented in Table 10.

      6(b)(iv)	Voluntary Submission
      
      EPA is unable to predict potential voluntary submissions, given none have been received to date. EPA conservatively assumes, as in previous, ICRs, that there will be one voluntary submission for one chemical annually. Activities are as listed in Section 6(a)(ii) plus associated recordkeeping.

 (1)	Estimated Annual Respondent Burdens and Costs  -  Voluntary Submissions
	This section presents voluntary submission unit burdens and costs, followed by total burden and cost. Table 12 presents components of unit burdens and unit costs for voluntary submissions. Given the unit values from Table 12, and applying the conditions of two agreements per year each involving one chemical, yields total burden and cost results presented in Table 13.

      6(b)(v)		Testing Exemption Applications

      As indicated previously, an entity subject to a test rule may apply for an exemption from one or all of the testing requirements imposed in a test rule if that testing will be, or has been performed by another party. There are basically two different scenarios under which a chemical manufacturer might prepare and submit an application to be exempt from a testing requirement imposed by a test rule. The first scenario involves a company who manufacturers the specified chemical for TSCA uses, but who will not be submitting the data because, for example, they joined a consortium that is expected to submit the data. The second scenario involves a company who manufacturers the covered chemical, but only for uses that are not covered by TSCA.

      In either case, it is difficult to predict how many exemption applications might be submitted to EPA in any one year. EPA assumes, as in previous, ICRs, that there will be two applications annually, each involving one chemical. EPA also assumes that each application would request the exemption from all of the testing. Activities related to an exemption application are as listed in Section 6(a)(ii) plus associated recordkeeping. 

       (1)	Estimated Annual Respondent Burdens and Costs  -  Testing Exemption 
      	Applications

	This section presents exemption application unit burdens and costs, followed by total burden and cost. Table 15 presents components of unit burdens and unit costs for testing exemption applications. Given the unit values from Table 15, and applying the conditions of two exemption applications per year, each involving one chemical, yields total burden and cost results presented in Table 16.

      6(c)	Estimating Agency Burden and Cost

      The cost and burden to the Agency to process, review, and analyze the information collected under TSCA section 4 test rules, testing agreements, voluntary testing programs, and testing exemption applications are discussed below and detailed in Tables 18 and 19. Table 18 lists the documents submitted to the agency (same counts as provided earlier in industry respondent burden and cost sections). Table 19 derives unit and total Agency burden and costs. Costs are based on the assumption that the Agency collection procedures are accomplished, on average, by a GS-13, Step 1 employee (see Table C in Attachment 3 for wage rate information). 

      The estimated unit burden for processing letters of intent and study plans (three hours), progress reports (one hour) is the same as from the previous ICRs and is believed to be reflective of current conditions. The estimated unit burden for final reports, including those from short-term studies, long-term studies, and from voluntary submissions is estimated at ten hours, as revised to reflect current conditions. The estimated unit burden for the Agency to process and review each exemption application is estimated at six hours, as revised to reflect current conditions. The total annual Agency burden and costs is estimated at 554 hours and $38,553.

Notes
1. See Table 3 for further explanation on test rule and testing agreement per-chemical reporting activities, year-by-year for a three-year period. Averages per year are rounded for presentation purposes but are not rounded for calculations of total reports per year received by the Agency.
2. Number of reports for test rules and testing agreements is obtained by separately multiplying the number of rules/agreements times the number of chemicals involved. A similar approach is taken for voluntary submissions and exemption applications.

      6(d)	Bottom Line Burden Hours and Costs

      Total Respondent Annual Hours and Costs

      Table 20 summarizes the estimated annual reporting burden and cost according to OMB-designated information collections, along with testing costs. With respect to reporting burden and cost, EPA estimates that this ICR will impose a total of 3,127 burden hours annually with a per response burden hour ranging from 8.5 for exemption applications to 249 hours for test rules/testing agreements (a response is on a per chemical basis). The associated per response reporting costs range from $641-$18,074 per chemical, respectively. For CDX registrations, per response burden is 0.53 hours or about 32 minutes per registration with an associated cost of $322. The total reporting costs are estimated at $222,887, with an additional $9 million in testing costs, yielding $9.2 million in total cost.

      6(e)	Reasons for Change in Burden

      This request represents a decrease of 626,766 hours from that currently in the OMB inventory (from 629,893 to 3,127 hours). As shown in Table 21, this decrease is due mainly to corrections to the previous renewal of this collection (-534,060 hours), plus reduced levels of activity in test rules given the decrease from 90 responses to 10 responses (-82,960 hours). Additionally, e-reporting produced burden reductions (-2,577 hours). Last, methodological corrections and updates produced newly defined unit burdens and adjustments to total burden (-7,169 hours). The decrease associated with e-reporting is a program change; the rest of the decrease is an adjustment.

Note: All unit and total burden estimates are reported in hours.
Footnotes:
[a] The breakdown according to IC is approximate, based on Supporting Statement posted on reginfo.gov, as adjusted by the final Notice of OMB Action, assuming the difference of 2,395 hours is entirely due to updates to the Test Rules burden estimate.
[b] Verification of totals from detailed calculations versus totals in IC Entry Tables confirmed that calculation errors occurred (US EPA 2013c).
[c] In the previous ICR, the conditions include six rules annually, each involving an average of 15 chemicals (90 responses). In this ICR renewal, conditions include two rules annually, each involving an average of 5 chemicals. 
[d] The primary effects of the e-reporting rule on burden estimates involve cutting recordkeeping burden to half its paper-based value, eliminating clerical burden in other activities, and adding an activity to account for electronic registration. Additionally non-labor costs are eliminated due to reductions in paper and postage costs. See Table D of Attachment 3.
[e] Two key changes are implemented in the methodology update. First, the response definition is changed from a per-activity to a per-chemical metric. A response is now defined as the collection of activities pertaining to the "standard" testing battery of 10 tests (seven short-term; three long term), all of which are performed on one specified chemical. Second, for test rules and testing agreements, the annual rate for activities is rigorously calculated (i.e., prorated) to accurately reflect the assumption that long term studies are three years in duration. Additionally, minor changes were made to activity-level burdens to improve consistency, including the addition of "Laboratory Review" to long-term studies' reports, and the adjustment to recordkeeping for Voluntary Submissions.



      6(f)	Burden Statement

      The annual public burden for this collection of information, which is approved under OMB Control No. 2070-0033, is estimated to range between 8.5 and 243 hours per response, not including CDX registration, and 0.53 hours per CDX registration. Burden is defined in 5 CFR 1320.3(b). An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a current and valid OMB control number. The OMB control numbers for EPA's regulations in title 40 of the CFR, after appearing in the Federal Register, are listed in 40 CFR part 9 and included on the related collection instrument or form, if applicable.

      The Agency has established a public docket for this ICR under Docket ID No. EPA-HQ-OPPT-2015-0436, which is available for online viewing at www.regulations.gov, or in person viewing at the EPA Docket Center (EPA/DC), EPA West, Room 3334, 1301 Constitution Ave., NW, Washington, DC. The EPA Docket Center Public Reading Room is open from 8:30 a.m. to 4:30 p.m., Monday through Friday, excluding legal holidays. The telephone number for the Reading Room is (202) 566-1744, and the telephone number for the Pollution Prevention and Toxics Docket is (202) 566-0280. You may submit comments regarding 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.
