Proposed Confidentiality Determinations for 8 Subparts and Proposed
Amendments to Table A-6 in Subpart A under the Mandatory Reporting
of Greenhouse Gases Rule

Environmental Protection
Agency
Action
	On December 22, 2011, the U.S. Environmental Protection Agency (EPA) proposed a rule that
would determine which data elements under six subparts of part 981 will be entitled to
confidential treatment under the Clean Air Act (CAA). These data elements will be reported to
EPA for the first time in 2012 under the Greenhouse Gas Reporting Program (GHGRP). The six
subparts are:
o Subpart L (Fluorinated Gas Production),
o Subpart DD (Electrical Transmission and Distribution Equipment Use),
o Subpart QQ (Importers and Exporters of Fluorinated Greenhouse Gases Contained in
Pre-charged Equipment or Closed-cell Foams),
o Subpart RR (Geologic Sequestration of Carbon Dioxide),
o Subpart SS (Electrical Equipment Manufacture or Refurbishment), and
o Subpart UU (Injection of Carbon Dioxide).
	This action also includes proposed confidentiality determinations for seven new data elements
recently added to subparts II (Industrial Wastewater Treatment) and TT (Industrial Waste
Landfills). The proposed rule also includes minor updates to Table A-6 in subpart A (General
Provisions) of part 98 to reflect the technical revisions recently made to subpart TT.
	EPA will release and withhold part 98 data in accordance with its confidential business
information (CBI) regulations for part 98 at 40 CFR 2.301.
	This proposal does not include subpart W (Petroleum and Natural Gas Systems) or subpart I
(Electronics Manufacturing). EPA will issue separate rulemaking actions in the future to
determine which data elements in subparts W and I will be entitled to confidential treatment.
	This proposal does not make confidentiality determinations for any data elements that are inputs
to emission equations. In an August 2011 action, EPA deferred reporting of inputs to emissions
equations for several years (76 FR 30782).
Background
 On October 30, 2009, EPA published the Mandatory Reporting of Greenhouse Gases rule (74 FR
56260) at 40 CFR part 98, requiring reporting from facilities that directly emit greenhouse gases
(GHGs) to the atmosphere ("direct emitters") as well as suppliers of products that would release
GHGs if combusted, oxidized, or used ("suppliers"). In November of 2010, EPA amended part
98 with reporting requirements for six additional source categories (subparts L, DD, QQ, RR, SS,
and UU).
1 On October 30, 2009, EPA published the Mandatory GHG Reporting Rule at 40 CFR part 98 for collecting
information regarding greenhouse gases from a broad range of industry sectors. Under part 98 and its subsequent
amendments, certain facilities and suppliers above specified thresholds are required to report greenhouse gas
information to EPA annually.

-------
	On May 26, 2011, EPA promulgated confidentiality determinations for data elements in 34
subparts of part 98, not including inputs to emission equations2. This action proposes
confidentiality determinations for data elements in six remaining subparts.
	On November 29, 2011, EPA finalized technical corrections, clarifying and other amendments to
part 98, including adding seven new data elements to the subparts II and TT reporting
requirements. This action proposes confidentiality determinations for these seven data elements,
so the total number of subparts affected by this action is eight.
	The CAA precludes "emission data" from being considered confidential and requires that such
data be available to the public.
Proposed Confidentiality Determinations
	In this proposal, EPA grouped similar data elements into data categories to make confidentiality
determinations for each element. This is the same approach that was used in the May 26, 2011,
action to make confidentiality determinations for data elements in 34 part 98 subparts.
	EPA evaluated part 98 data elements for six subparts (subparts L, DD, QQ, RR, SS, and UU) to
determine which data elements are emission data and, therefore, are not eligible for confidential
treatment.
	For the remaining data elements included in this proposal, EPA evaluated whether the data
elements qualify as CBI .
	For a list of the data elements along with the corresponding final confidentiality determinations,
see the memorandum "Proposed Data Category Assignments for data elements in 40 CFR Part
98, subparts L, DD, II, QQ, RR, SS, TT, and UlT at:
http://www.epa.gov/ghgreporting/reporters/cbi/index.html.
Next Steps and Implementation
	The notice of confidentiality determination will be published in the Federal Register shortly and will
be available at www.regulations.gov.
	A prepublication version is available on our Web site at:
http://www.epa.gov/ghgreporting/reporters/notices/index.html
	The public comment period is open for 60 days after publication in the Federal Register.
	After consideration of public comments, we intend to issue a final notice in 2012.

2	On August 25, 2011, EPA finalized an action to defer until 2013 and 2015 the reporting of data elements that are
inputs to emission equations. That action covered inputs to equations in all 42 source categories of part 98, including
the six source categories that are the subject of this proposed rule.
