**MEMORANDUM To:**  Docket EPA

- 201 2
- 0934 **From:** Rachel Schmeltz, U.S. EPA, Climate Change Division **Date:** September 30 , 2013 **Subject:** D ata category assignments and confidentiality determinations for new and

substantially

revised data elements in the Final “ 2013 Revisions to the Greenhouse Gas Reporting Rule and Confidentiality Determinations for New or Substantially Revised Data Elements
. ” In this memorandum, we show the final data category assignments for new and substantially revised data e lements that are added or revised in fourteen subparts in the 2013 Revisions to the Greenhouse Gas Reporting Rule and Confidentiality Determinations for New or Substantially Revised Data Elements

. These subparts include subparts A **,** C, H, K, X, Y, Z, AA, FF, HH, NN, QQ, RR, TT , and UU. T he table s below show the data category assignment of each data reporting element and the confidentialit y determination s (categorical through category assignment or individual) for these data elements , e xcept for those assigned to the inputs to emission equations data category . 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 s upplier data categories. The EPA did not make categorical determinations 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) . T he confidentiality determinations for data elements assigned to those c ategories were made on an element
- by
- element basis
. The 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. In this action, the EPA is assign ing 26 new or substantially revised data elements to data categories for which EPA issued categorical confidentiality determinations and is applying the categorical determinations to the assigned data elements
. The EPA i s assign ing 16 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 making confidentially

determinations for these reporting elements individually
. We are not making data categories or confidenti alit y determinations for 2 data elements where the data element s are the same as another data element in the same subpart for which a confidentialit y determination has already been finalized. The table s below identify the data categories and the

confidentiality

determination for the new or revised data elements in the amendments
. The EPA is assign ing 15 new or revised data elements to the inputs to emission equations category but is not assigning confidentiality determinations for them. For de scriptions of the data categories and the categorical confidentiality determinations made for these categories , see the preamble s to the proposed and final rulemaking s: Proposed Confidentiality Determinations for Data Required Under the Mandatory Greenhous e Gas Reporting Rule and Proposed Amendment to Special Rules Governing Certain Information Obtained Under the Clean Air Act published on July 7, 2010 ( 75 FR 39094) ; and Confi
