Abstract: Title V of the Clean Air Act (CAA or Act) requires states to develop and implement a program for issuing operating permits to all sources that fall under any Act definition of ‘‘major’’ and certain other non-major sources that are subject to federal air quality regulations. The Act further requires the EPA to develop regulations that establish the minimum requirements for those state operating permits programs and to oversee implementation of the state programs. The EPA regulations setting forth requirements for the state operating permit program are found at 40 CFR part 70. The part 70 program is designed to be implemented primarily by state, local and tribal permitting authorities in all areas where they have jurisdiction. In order to receive an operating permit for a major or other source subject to the permitting program, the applicant must conduct the necessary research, perform the appropriate analyses and prepare the permit application with documentation to demonstrate that its facility meets all applicable statutory and regulatory requirements. Specific activities and requirements are listed and described in the Supporting Statement for the 40 CFR part 70 ICR. Under 40 CFR part 70, state, local and tribal permitting authorities review permit applications, provide for public review of proposed permits, issue permits based on consideration of all technical factors and public input and review information submittals required of sources during the term of the permit. Also, under 40 CFR part 70, the EPA reviews certain actions of the permitting authorities and provides oversight of the programs to ensure that they are being adequately implemented and enforced. Consequently, information prepared and submitted by sources is essential for sources to receive permits, and for federal, state, local and tribal permitting authorities to adequately review the permit applications and thereby PO 00000 Frm 00035 Fmt 4703 Sfmt 4703 48693 properly administer and manage the program. Information that is collected is handled according to the EPA’s policies set forth in title 40, chapter 1, part 2, subpart B—Confidentiality of Business Information (see 40 CFR part 2). See also section 114(c) of the Act. Form Numbers: None. Respondents/affected entities: Industrial plants (sources); state, local and tribal permitting authorities. Respondent’s obligation to respond: mandatory (see 40 CFR part 70). Estimated number of respondents: 14,201 sources and 117 state, local and tribal permitting authorities. Frequency of response: On occasion. Total estimated burden: 4,756,110 hours (per year). Burden is defined at 5 CFR 1320.03(b). Total estimated cost: $325,175,507 (per year). There are no annualized capital or operation & maintenance costs. Changes in Estimates: There is an increase of 17,185 hours in the total estimated respondent burden compared with the ICR currently approved by OMB. This increase is due to updated estimates of the number of sources and permits subject to the part 70 program, rather than any change in federal mandates. Dated: August 26, 2021.

SUPPLEMENTARY INFORMATION: I. General Information khammond on DSKJM1Z7X2PROD with NOTICES A. Does this action apply to me? This action is directed to the public in general and may be of interest to entities that manufacture (including import) a chemical substance regulated under TSCA (e.g., entities identified under North American Industrial Classification System (NAICS) codes 325 and 324110). The action may also be of interest to chemical processors, distributors in commerce, and users; non-governmental organizations in the environmental and public health sectors; state and local government agencies; and members of the public. Since other entities may also be interested, the Agency has not VerDate Sep<11>2014 20:08 Aug 30, 2021 Jkt 253001 attempted to describe all the specific entities and corresponding NAICS codes for entities that may be interested in or affected by this action. B. What is the Agency’s authority for taking this action? The final scope document is issued pursuant to TSCA section 6(b)(4)(D) and EPA’s implementing regulations at 40 CFR 702.41(c)(8). C. What action is the Agency taking? EPA is publishing the final scope of the risk evaluation for DINP under TSCA. Through the risk evaluation process, EPA will determine whether the category of chemical substances presents an unreasonable risk of injury to health or the environment under the conditions of use, as determined by the Administrator, in accordance with TSCA section 6(b)(4). II. Background TSCA allows chemical manufacturers to request an EPA-conducted risk evaluation of a chemical substance under 40 CFR 702.37. On May 24, 2019, EPA received a manufacturer request for a risk evaluation of DINP (Ref. 1). On December 2, 2019, the Agency granted the request and subsequently initiated the scoping process for a risk evaluation for this category of chemical substances on January 2, 2020. Pursuant to 40 CFR 702.41(c)(7), EPA announced the availability of and sought public comment on the draft scope document for the risk evaluation to be conducted for DINP under TSCA (85 FR 76072, November 27, 2020) (FRL–10017–15) (Ref. 2). The purpose of risk evaluation is to determine whether a chemical substance, or group of chemical substances, presents an unreasonable risk to health or the environment, under the conditions of use, including an unreasonable risk to a relevant potentially exposed or susceptible subpopulation (15 U.S.C. 2605(b)(4)(A)). As part of this process, EPA must evaluate both hazards and exposures for the conditions of use; describe whether aggregate or sentinel exposures were considered and the basis for consideration; not consider costs or other nonrisk factors; take into account where relevant, likely duration, intensity, frequency, and number of exposures and describe the weight of the scientific evidence for hazards and exposures (15 U.S.C. 2605(b)(4)(F)). This process will culminate in a determination of whether or not the category of chemical substances presents an unreasonable risk of injury to health or the environment under the PO 00000 Frm 00036 Fmt 4703 Sfmt 4703 conditions of use (15 U.S.C. 2605(b)(4)(A); 40 CFR 702.47). III. Information and Comments Received on the Draft Scope In the Federal Register of November 27, 2020 (Ref. 2), EPA announced the availability of the draft scope document for the risk evaluation to be conducted for DINP under TSCA and invited public comments on EPA’s draft scope document, including additional data or information relevant to the category of chemical substances or that otherwise could be useful to the Agency in finalizing the scope of the risk evaluation. To the extent that comments provided information on conditions of use, as well as other elements of the draft scope document. Those comments and other submitted information (e.g., relevant studies and assessments) were used to inform revisions to the draft scope document and may be considered in subsequent phases of the risk evaluation process. EPA received six unique submissions for DINP, including comments from potentially affected businesses or trade associations, environmental and public health advocacy groups (some submissions were signed by more than one group), a group of state attorneys general, and one anonymous comment. Comments addressed the overall approach to the risk evaluation process (e.g., collection, consideration, and systematic review of relevant information), the specific elements of the scope document (e.g., hazard, exposure, and potentially exposed or susceptible subpopulations), information specific to the chemical substances (e.g., relevant studies, assessments, and conditions of use), and topics beyond the draft scope document phase of the process (e.g., risk management). EPA considered those comments, as applicable and appropriate, in developing the final scope document. Concurrently with the publication of the final scope document, EPA is publishing a response to comments document that contains a comprehensive summary of and response to public comments received on the DINP draft scope document. The comprehensive response to comments document is available in the docket EPA–HQ–OPPT–2019–0436 (Ref. 3). IV.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    This action is directed to the public in general and may be of 
interest to entities that manufacture (including import) a chemical 
substance regulated under TSCA (e.g., entities identified under North 
American Industrial Classification System (NAICS) codes 325 and 
324110). The action may also be of interest to chemical processors, 
distributors in commerce, and users; non-governmental organizations in 
the environmental and public health sectors; state and local government 
agencies; and members of the public. Since other entities may also be 
interested, the Agency has not attempted to describe all the specific 
entities and corresponding NAICS codes for entities that may be 
interested in or affected by this action.

B. What is the Agency's authority for taking this action?

    The final scope document is issued pursuant to TSCA section 
6(b)(4)(D) and EPA's implementing regulations at 40 CFR 702.41(c)(8).

C. What action is the Agency taking?

    EPA is publishing the final scope of the risk evaluation for DINP 
under TSCA. Through the risk evaluation process, EPA will determine 
whether the category of chemical substances presents an unreasonable 
risk of injury to health or the environment under the conditions of 
use, as determined by the Administrator, in accordance with TSCA 
section 6(b)(4).

II. Background

    TSCA allows chemical manufacturers to request an EPA-conducted risk 
evaluation of a chemical substance under 40 CFR 702.37. On May 24, 
2019, EPA received a manufacturer request for a risk evaluation of DINP 
(Ref. 1). On December 2, 2019, the Agency granted the request and 
subsequently initiated the scoping process for a risk evaluation for 
this category of chemical substances on January 2, 2020. Pursuant to 40 
CFR 702.41(c)(7), EPA announced the availability of and sought public 
comment on the draft scope document for the risk evaluation to be 
conducted for DINP under TSCA (85 FR 76072, November 27, 2020) (FRL-
10017-15) (Ref. 2).
    The purpose of risk evaluation is to determine whether a chemical 
substance, or group of chemical substances, presents an unreasonable 
risk to health or the environment, under the conditions of use, 
including an unreasonable risk to a relevant potentially exposed or 
susceptible subpopulation (15 U.S.C. 2605(b)(4)(A)). As part of this 
process, EPA must evaluate both hazards and exposures for the 
conditions of use; describe whether aggregate or sentinel exposures 
were considered and the basis for consideration; not consider costs or 
other nonrisk factors; take into account where relevant, likely 
duration, intensity, frequency, and number of exposures and describe 
the weight of the scientific evidence for hazards and exposures (15 
U.S.C. 2605(b)(4)(F)). This process will culminate in a determination 
of whether or not the category of chemical substances presents an 
unreasonable risk of injury to health or the environment under the 
conditions of use (15 U.S.C. 2605(b)(4)(A); 40 CFR 702.47).

III. Information and Comments Received on the Draft Scope

    In the Federal Register of November 27, 2020 (Ref. 2), EPA 
announced the availability of the draft scope document for the risk 
evaluation to be conducted for DINP under TSCA and invited public 
comments on EPA's draft scope document, including additional data or 
information relevant to the category of chemical substances or that 
otherwise could be useful to the Agency in finalizing the scope of the 
risk evaluation. To the extent that comments provided information on 
conditions of use, as well as other elements of the draft scope 
document. Those comments and other submitted information (e.g., 
relevant studies and assessments) were used to inform revisions to the 
draft scope document and may be considered in subsequent phases of the 
risk evaluation process.
    EPA received six unique submissions for DINP, including comments 
from potentially affected businesses or trade associations, 
environmental and public health advocacy groups (some submissions were 
signed by more than one group), a group of state attorneys general, and 
one anonymous comment.
    Comments addressed the overall approach to the risk evaluation 
process (e.g., collection, consideration, and systematic review of 
relevant information), the specific elements of the scope document 
(e.g., hazard, exposure, and potentially exposed or susceptible 
subpopulations), information specific to the chemical substances (e.g., 
relevant studies, assessments, and conditions of use), and topics 
beyond the draft scope document phase of the process (e.g., risk 
management). EPA considered those comments, as applicable and 
appropriate, in developing the final scope document. Concurrently with 
the publication of the final scope document, EPA is publishing a 
response to comments document that contains a comprehensive summary of 
and response to public comments received on the DINP draft scope 
document. The comprehensive response to comments document is available 
in the docket EPA-HQ-OPPT-2019-0436 (Ref. 3).
