MEMORANDUM 

To: Docket EPA-HQ-OAR-2009-0924 

From: Lisa Grogan-McCulloch, EPA/Climate Change Division and 

 Ruth Mead and Amanda Baynham, ERG 

Date: July 15, 2010 

Subject: Data category assignments for the proposed new and revised 40 CFR part 98 data 

elements addressed in the Proposed Confidentiality Determinations for Data Required 

under the Mandatory Greenhouse Gas Reporting Rule: Supplemental Proposal 

Today, EPA signed the following two proposals: Revision of Certain Provisions of the 

Mandatory Reporting of Greenhouse Gases Rule: Proposed Rulemaking (Amendments 

Proposal); and Proposed Confidentiality Determinations for Data Required under the 

Mandatory Greenhouse Gas Reporting Rule: Supplemental Proposal (Supplemental 

Confidentiality Proposal). In this memorandum, we show the data category assignments and 

proposed confidentiality determinations made in today’s Supplemental Confidentiality Proposal 

for the new and revised data elements proposed under the concurrent Amendments Proposal. 

Background

EPA published the Mandatory Greenhouse Gas Reporting Rule on October 30, 2009 (74 

FR 56260). This rule includes data reporting requirements, codified at 40 CFR Part 98, which 

are designed to collect the information necessary to characterize and quantify greenhouse gas 

(GHG) emissions from a broad range of industry sectors and which apply to direct emitters of 

GHGs (e.g., glass manufacturing facilities) and to suppliers of products that when used may 

result in the release of GHGs into the atmosphere (e.g., fossil fuels and industrial GHGs). 

During the development of Part 98, EPA received a number of comments from businesses and 

other stakeholders regarding their concern that some of the data reported consisted of trade 

secrets and other confidential business information that, if released to the public, would likely 

harm their competitive position. To address these concerns, EPA issued the Proposed 

Confidentiality Determinations for Data Required under the Mandatory Greenhouse Gas 

Reporting Rule and Proposed Amendment to Special Rules Governing Certain Information 

Obtained under the Clean Air Act (Confidentiality Proposal) on July 7, 2010 (75 FR 39094) to 

establish which Part 98 data elements are entitled to confidential treatment. The Confidentiality 

Proposal proposes confidentiality determinations for part 98 data elements, as well as 

amendments to EPA’s Special Rules governing certain information obtained under the Clean Air 

Act at 40 CFR 2.301. 

Today, EPA signed the Amendments Proposal, which proposes amendments to Part 98 

that, if finalized, would make clarifying and technical changes to reporting requirements. 

Proposed revisions include allowing greater flexibility or simplified calculation methods for 

certain sources, amending data reporting requirements and definitions, and providing technical 

1
corrections, clarifying and other amendments. Since the Amendments Proposal was published 

after the Confidentiality Proposal, EPA was not able to address the proposed revisions to the 

reported data elements in the initial Confidentiality Proposal. Therefore, EPA also signed today 

the Supplemental Confidentiality Proposal to address the confidentiality of the data elements in 

the Amendment Proposal. In this memorandum, we show the data category assignments and 

proposed confidentiality determinations made under the Supplemental Confidentiality Proposal 

for the new and revised data elements proposed under the concurrent Amendments Proposal. 

For information on EPA’s approach to making confidentiality determinations for these data 

elements and the rationale for EPA’s proposed determinations, please see the preambles to the 

July 7, 2010 Confidentiality Proposal and today’s Supplemental Confidentiality Proposal. 

Copies of these proposals are available on EPA’s Web site: 

http://www.epa.gov/climatechange/emissions/CBI.html 

As discussed in the Confidentiality Proposal, the first step to making the proposed 

confidentiality determinations was grouping similar data elements together into data categories. 

EPA developed a total of 22 distinct data categories, with 11 data categories for the direct emitter 

source categories and 11 for the supplier source categories. The data elements within a given 

data category are either the same type of data (e.g., emissions, facility identification information) 

or have similar characteristics (e.g., are inputs used to calculate emissions). For example, the 

data category for inputs to equations includes many different types of data elements, such as fuel 

consumption, product output, and carbon content. However, they all share the same 

characteristic of being used to calculate GHG emissions. For a list of the 22 data categories see 

Appendix A to this memorandum. 

In the Confidentiality Proposal, EPA proposed confidentiality determinations on a 

category basis for 19 of the 22 data categories. For the remaining three data categories, EPA 

proposed confidentiality determinations on a data element basis, rather than for the data category 

as a whole. The data category assignments and proposed confidentiality determinations for the 

data elements addressed in the Confidentiality Proposal are listed in a memorandum titled Data 

category assignments for reporting elements to be reported under 40 CFR part 98 and its 

amendments (See EPA-HQ-OAR-2009-0924-0007), which is available online at 

www.regulations.gov. 

 

Data Elements Addressed in the Supplemental Confidentiality Proposal

In the Amendments Proposal, EPA proposed changes that would clarify and revise 

certain reporting requirements. Some of the proposed changes to the reporting requirements are 

editorial corrections, such as corrections to rule citations and cross-references. Other changes 

consist of minor revisions to existing reporting requirements, such as changes to clarify what 

type of data facilities and suppliers should report. For example, some changes to existing 

reporting requirements clarify whether the data should be reported at the facility or unit-level. 

Other proposed changes include allowing greater flexibility or simplified calculation methods for 

certain sources, amending data reporting requirements and definitions. In some cases, these 

changes include addition of new reporting requirements and deletion of existing reporting 

requirements. Since these changes to the reporting requirements were proposed after the 

publication of the Confidentiality Proposal, they were not addressed in the initial Confidentiality 

Proposal and are therefore addressed in today’s Supplemental Confidentiality Proposal.

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

confidentiality determinations made under the Supplemental Confidentiality Proposal for the 

new and revised data elements proposed under the Amendments Proposal. These data elements 

are in 40 CFR part 98, subpart A and the following Part 98 subparts, as promulgated in 2009: 

 subpart C, General Stationary Fuel Combustion Sources; 

 subpart D, Electricity Generation; 

 subpart F, Aluminum Production; 

 subpart G, Ammonia Manufacturing; 

 subpart V, Nitric Acid Production; 

 subpart X, Petrochemical Production; 

 subpart Y, Petrochemical Production; 

 subpart OO, Suppliers of Industrial Greenhouse Gases; and 

 subpart PP, Suppliers of Carbon Dioxide. 

The lists of proposed new and revised data elements included in each data category are 

shown in Appendix B to this memorandum. Tables B-1 and B-2 list the data category 

assignments for the proposed new and revised data elements in the direct emitter and supplier 

data categories, respectively. The data category assignments for proposed revised data elements 

are also included in these tables. The data category assignments for the proposed revised data 

elements remain unchanged from those proposed in the July 7, 2010 Confidentiality Proposal. 

The Amendments Proposal also includes changes to the rule citations for several of the 

existing data elements due to the proposed deletions and additions of reporting requirements. 

The proposed citation changes do not change the data elements’ contents or their data category 

assignments. Table C-1 in Appendix C to this memorandum shows a list of these data elements 

with the current and proposed new rule citations.
