Description:  TITLE: Revisions and Confidentiality Determinations for Data Elements Under the 
Greenhouse Gas Reporting Rule  
AGENCY: Environmental Protection Agency (EPA)  
ACTION: Supplemental notice of proposed rulemaking  
SUMMARY: The EPA is issuing this supplemental proposal that would amend specific provisions in 
the Greenhouse Gas Reporting  Rule to improve the quality and consistency of the rule by providing 
for the collection of improved data that would better inform and be relevant to a wide variety of 
Clean Air Act provisions that the EPA carries out. The EPA recently evaluat ed the requirements of

  the Greenhouse Gas Reporting Rule to identify areas of improvement, including updates to the 
existing calculation, recordkeeping, and reporting requirements, and requested information for 
collection of additional data to understand n ew source categories in a proposed rule ( 21 June 2022 ). 
In this notification, the EPA is proposing additional amendments to the Greenhouse Gas Reporting 
Rule, including u pdates to the General Provisions to reflect revised global warming potentials, and 
is proposing to require reporting of greenhouse gas data from additional sectors --specifically energy 
consumption; coke calcining; ceramics production; calcium carbide produ ction; and caprolactam, 
glyoxal, and glyoxylic acid production. The EPA is also proposing additional revisions that would 
improve implementation of the Greenhouse Gas Reporting Rule, such as updates to emissions 
calculation methodologies; revisions to repo rting requirements to improve verification of reported 
data and the accuracy of the data collected; and other minor technical amendments, corrections, or 
clarifications. The EPA intends to consider the information received in response to this supplemental 
proposal prior to finalizing the amendments to the Greenhouse Gas Reporting Rule proposed on 21 
June 2022. This action also proposes to establish and amend confidentiality determinations for the 
reporting of certain data elements to be added or substantial ly revised in these proposed 
amendments.  
DATES: Comments must be received on or before 21 July 2023. Comments on the information 
collection provisions submitted to the Office of Management and Budget (OMB) under the Paperwork 
Reduction Act (PRA) are best a ssured of consideration by OMB if OMB receives a copy of your 
comments on or before 21 June 2023.  
The EPA does not plan to conduct a public hearing unless requested. If anyone contacts us requesting 
a public hearing on or before 30 May 2023, we will hold a  virtual public hearing. See SUPPLEMENTARY 
INFORMATION for information on requesting and registering for a public hearing.
