MEMORANDUM 

To: Docket EPA-HQ-OAR-2015-0526

From: Rachel Schmeltz, Lisa Grogan-McCulloch, U.S. EPA, Climate Change Division

Date: December 11, 2015

Subject: Proposed Data Category Assignments and Confidentiality Determinations for Data 

Elements in the Proposed 2015 Revisions

In this memorandum, we show the proposed data category assignments for new and substantially 

revised data elements in 21 subparts that are proposed to be added or revised in the 2015 

Revisions and Confidentiality Determinations for Data Elements Under the Greenhouse Gas 

Reporting Rule. These subparts include subparts A, C, E, F, G, I, O, S, V, X, Y, Z, CC, DD, FF, 

HH, II, NN, OO, PP, and RR.. This memorandum also shows the proposed data category 

assignments for 27 existing data elements in subparts I, Z, MM, NN, PP, and RR that are not 

revised in the proposed amendments. These include 22 data elements in subparts I, Z, MM, and 

RR for which the EPA had not made confidentiality determinations under Part 98, as well as two 

data elements in subpart NN for which a previous final confidentiality determination is proposed 

to be revised because of new information indicating the data element is not entitled to 

confidential treatment under the provisions in 40 CFR 2.208. We are also proposing 

confidentiality determinations for three data elements in subpart PP that were included in the 

final rule “Standards of Performance for Greenhouse Gas Emissions From New Stationary 

Sources: Electric Utility Generating Units Standards of Performance for Greenhouse Gas 

Emissions from New, Modified, and Reconstructed Stationary Sources: Electric Utility 

Generating Units” (Docket Id. No. EPA-HQ-OAR-2013-0495). The tables below show the 

proposed assignment of each data reporting element into data categories for the purposes of 

making categorical CBI determinations, except for those designated as inputs to emission 

equations. The tables also show the proposed confidentiality determinations (categorical through 

category assignment or individual) for these data elements.

In the May 26, 2011, Final CBI rule (76 FR 30782), the EPA created 22 data categories for part 

98 data elements, assigned individual data elements in 34 subparts to appropriate data categories, 

and issued categorical confidentiality determinations for nine of the direct emitter data categories 

and eight of the supplier data categories. For two of the direct emitter data categories 

(“Unit/Process ‘Static’ Characteristics That are Not Inputs to Emission Equations” and 

“Unit/Process ‘Operating’ Characteristics That are Not Inputs to Emission Equations”) and three 

supplier data categories (GHGs Reported, Production/Throughput Quantities and Composition, 

and Unit/Process Operating Characteristics), EPA determined that the categories were not 

emission data but did not make categorical determinations of CBI or Not CBI. As a result, the 

CBI determinations for data elements assigned to those categories were made on an element-byelement basis. EPA has been following this approach in subsequent rulemakings to make 

confidentiality determinations for new and substantially revised data elements established in 

subsequent amendments to part 98. EPA did not make any confidentiality determination for data 

elements assigned to the inputs to emission equations category. 
2

In this action, the EPA is similarly proposing to assign 66 new or substantially revised data 

elements to data categories for which EPA issued categorical confidentiality determinations and 

apply the categorical determinations to the assigned data elements. The EPA is proposing to 

assign 51 new or revised data elements to the “Unit/Process ‘Static’ Characteristics That are Not 

Inputs to Emission Equations” and “Unit/Process Operating Characteristics That are Not Inputs 

to Emission Equations” direct emitter data categories and the “Production/Throughput Quantities 

and Composition” and “Unit/Process Operating Characteristics” supplier data categories and 

make confidentially determinations for these reporting elements individually. We are proposing 

to make an individual CBI determination for one new data element in subpart FF for which we 

are not assigning a data category. Rationales for individual CBI determinations are discussed in 

the preamble to this proposed rule. We are not proposing a data category or confidentiality 

determination for two revised data elements where the data element refers to another data 

element for which a CBI determination has already been finalized. 

The EPA is also proposing to assign three existing data elements to the supplier data category 

“Amount and Composition of Materials Received” and apply the categorical determination to the 

assigned data elements. The EPA is also proposing to assign 40 existing data elements to the 

“Unit/Process ‘Static’ Characteristics That are Not Inputs to Emission Equations” and 

“Unit/Process Operating Characteristics That are Not Inputs to Emission Equations” direct 

emitter data categories and the “Production/Throughput Quantities and Composition” and 

“Unit/Process Operating Characteristics” supplier data categories and make confidentially 

determinations for these reporting elements individually.

The tables below identify the proposed data categories and the confidentiality determinations for 

the new, revised, and existing data elements in each direct emitter (Appendix A-1) and supplier 

(Appendix A-2) subpart in the proposed revisions. Appendix A-1 also includes six new or 

revised data elements proposed to be assigned to the inputs to emission equations category, but 

EPA is not assigning confidentiality determinations for them. Inputs to emissions equations and 

their associated potential disclosure concerns, if any, are discussed in section III of the preamble 

to the proposed rule, as specified in Appendix A-1. For additional information on the EPA’s 

approach to evaluating data elements assigned to the inputs to emission equations category for 

potential competitive harm, see the notices Change to the Reporting Date for Certain Data 

Elements Required Under the Mandatory Reporting of Greenhouse Gases Rule (76 FR 53057, 

August 25, 2011) and Revisions to Reporting and Recordkeeping Requirements, and 

Confidentiality Determinations Under the Greenhouse Gas Reporting Program, (79 FR 63750,

October 24, 2014), as well as the memoranda “Process for Evaluating and Potentially Amending 

Part 98 Inputs to Emission Equations” (available in Docket Id. No. EPA-HQ-OAR-2010-0929), 

“Evaluation of Inputs Deferred until 2013," December 17, 2012 (available in the docket to this 

rulemaking) and “Final Evaluation of Competitive Harm from Disclosure of 'Inputs to 

Equations’ Data Elements Deferred to March 31, 2015," September 2014 (available in Docket 

Id. No. EPA-HQ-OAR-2010-0929).

for these categories, see the preambles to the proposed and final rulemakings: Proposed
