Ozone Transport Commission 

Recommendation That EPA Require 

Daily Limits for Emissions of Nitrogen 

Oxides From Certain Sources in 

Pennsylvania: Extension of Comment 

Period 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice; extension of comment 

period. 

SUMMARY: On January 15, 2021, EPA 

issued a Federal Register notice of 

public hearing and supplemental 

information regarding a 

recommendation submitted by the 

Ozone Transport Commission (OTC) to 

address ongoing ozone pollution in the 

northeastern United States. The OTC 

has recommended that EPA require 

Pennsylvania to revise its state 

implementation plan (SIP) to include 

additional control measures that would 

establish daily limits on emissions of 

nitrogen oxides (NOX) from coal-fired 

electricity generating units (EGUs) with 

already-installed selective catalytic 

reduction (SCR) or selective 

noncatalytic reduction (SNCR) controls. 

This document extends the comment 

period for 30 days, from March 8, 2021 

to April 7, 2021. 

DATES: Comments identified by docket 

identification (ID) number EPA–HQ– 

OAR–2020–0351 must be received on or 

before April 7, 2021. 

ADDRESSES: Follow the detailed 

instructions provided under ADDRESSES

in the Federal Register document of 

January 15, 2021 (86 FR 4049).

SUPPLEMENTARY INFORMATION: This 

document extends the public comment 

period established in the Federal 

Register document of January 15, 2021 

(86 FR 4049), which opened a public 

comment period for supplemental 

information concerning a 

recommendation submitted by the OTC 

to EPA under CAA section 184(c). In the 

January 15, 2021 notice, EPA discussed 

the relevant statutory provisions, 

described the steps EPA is following to 

facilitate public participation in the 

Agency’s process for reaching a decision 

on the recommendation, discussed the 

OTC recommendation—including the 

Delaware, Maryland, and New Jersey 

rules that OTC believes should become 

the standards for EPA’s approval of a 

responsive SIP revision from 

Pennsylvania, identified the potentially 

affected Pennsylvania EGUs, and 

summarized the supporting information 

provided by the OTC. EPA further 

provided information on the potentially 

affected EGUs’ historical emissions and 

on regulatory context that may be 

relevant to EPA’s decision on the 

recommendation. 

EPA is hereby extending the public 

comment period, which was set to end 

on March 8, 2021, to April 7, 2021. After 

considering a request to extend the 

comment period received from a 

stakeholder, EPA is extending the 

comment period for the following 

reasons: (1) The legal and technical 

complexity of the analysis of the 

recommendation; (2) the need for 

stakeholders to consider the interaction 

of this decision with other actions the 

Agency is concurrently considering; (3) 

the stakeholders’ need for additional 

time to review and develop constructive 

comments and related analyses on the 

recommendation. To submit comments, 

or access the docket, please follow the 

detailed instructions provided under 

ADDRESSES in the Federal Register 

document of January 15, 2021. If you 

have any questions regarding the 

applicability of this action to a 

particular entity, consult the person 

listed under FOR FURTHER INFORMATION

Chemical Category for OctahydroTetramethyl-Naphthalenyl-Ethanone 

(OTNE); Manufacturer Request for Risk 

Evaluation Under the Toxic 

Substances Control Act (TSCA); Notice 

of Availability and Request for 

Comments 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: The Environmental Protection 

Agency (EPA) is announcing the 

availability of and soliciting public 

comment on a manufacturer request for 

a risk evaluation under the Toxic 

Substances Control Act (TSCA) of 

ethanone, 1-(1,2,3,4,5,6,7,8-octahydro2,3,5,5-tetramethyl-2-naphthalenyl), 

ethanone, 1-(1,2,3,4,5,6,7,8-octahydro2,3,8,8-tetramethyl-2-naphthalenyl), 

ethanone, 1-(1,2,3,4,6,7,8,8a-octahydro2,3,8,8-tetramethyl-2-naphthalenyl), and 

ethanone, 1-(1,2,3,5,6,7,8,8a-octahydro2,3,8,8-tetramethyl-2-naphthalenyl) 

(collectively, ‘‘OTNE’’). The request was 

made by International Flavors and 

Fragrances, Inc. (IFF), Privi Organics 

USA Corporation (Privi), and DRT 

America, Inc. (DRT) through the OTNE 

Consortium. EPA conducts risk 

evaluations to determine whether a 

chemical substance presents an 

unreasonable risk of injury to health or 

the environment without consideration 

of costs or other non-risk factors, 

including an unreasonable risk to 

potentially exposed or susceptible 

subpopulations, under the conditions of 

use. In the docket associated with this 

request is the manufacturer request for 

an EPA-conducted risk evaluation and 

possible additional conditions of use 

EPA has identified for inclusion within 

the scope of a risk evaluation of OTNE. 

EPA specifically invites public 

comment on the inclusion of any 

additional conditions of use and 

potentially exposed or susceptible 

subpopulations. The Agency is in the 

process of broadly re-examining how it 

intends to implement these and other 

provisions of amended TSCA including 

determining how new executive orders 

and other direction provided by the 

Biden-Harris Administration will be 

addressed. This process would benefit 

greatly from stakeholder feedback. After 

considering comments received in 

response to this solicitation, EPA will 

determine whether to grant or deny the 

manufacturer request. All TSCA risk 

evaluations, whether EPA-initiated or 

manufacturer-requested, will be 

conducted in the same manner. 

DATES: Comments must be received on 

or before April 5, 2021.

identified by docket identification (ID) 

number EPA–HQ–OPPT–2020–0738,
