review and approval. At that time, the 

EPA will issue another Federal Register 

notice to announce the submission of 

the ICR to OMB and the opportunity to 

submit additional comments to OMB. 

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 

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.

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).
