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).

FOR FURTHER INFORMATION CONTACT: Beth Murray, Clean Air Markets 
Division, Office of Atmospheric Programs, Office of Air and Radiation, 
Environmental Protection Agency, 202-343-9115, murray.beth@epa.gov.

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 CONTACT.

Director, Office of Atmospheric Programs.
