MEMORANDUM

To: Docket EPA-HQ-OAR-2012-0934

From: Rachel Schmeltz, U.S. EPA, Climate Change Division

Date: March 1, 2013

Subject: Proposed data category assignments and confidentiality det erminations for new and

substantially revised data elements in the proposed “2013 Revi sions to the

Greenhouse Gas Reporting Rule and Confidentiality Determi nations for New or

Substantially Revised Data Elements”.

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

revised data elements in fourteen subparts that are propo sed to be added or revised in the 2013

Revisions to the Greenhouse Gas Reporting Rule and Confidentiality Dete rminations for New or

Substantially Revised Data Elements. These subparts include subparts A



# , H, K, X, Y, Z, AA, FF,

HH, NN, QQ, RR, TT, and UU. The tables below show the proposed assignment of each data

reporting element into data categories. The tables also show the proposed confidentiality

determinations (categorical through category assignment or individual) for these data elements

except for those assigned to the inputs to equations data c ategory.

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

98 data elements, assigned individual data elements in 34 sub parts to appropriate data categories,

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

categories and eight of the supplier data categories. EP A did not make categorical determinations

for two of the direct emitter data categories (“Unit/Pro cess ‘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/Pro cess Operating

Characteristics), and the CBI determinations for data ele ments assigned to those categories were

made on an element-by-element basis. EPA has been fol lowing 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 t o emission equations category. In this

action, the EPA is similarly proposing to assign 26 new or substantially revised data elements to

data categories for which EPA issued categorical confident iality determinations and apply the

categorical determinations to the assigned data elements . The EPA is proposing to assign 16 new

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

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

Emission Equations” direct emitter data categories and th e “Production/Throughput Quantities

and Composition” and “Unit/Process Operating Characteristi cs” supplier data categories and

make confidentially determinations for these reporting el ements individually. We are not

proposing data categories or confidentiality determinations for 2 data elements where the data

elements refer to another data element for which a CBI determination has already been finalized.

The tables below identify the proposed data categories and t he confidentiality determination for

# 2

the new or revised data elements in the proposed amendme nts. EPA is proposing to assign 13

new or revised data elements to the inputs to emission equa tions category but is not proposing

confidentiality determinations for them.

For descriptions of the data categories and the categoric al confidentiality determinations made

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