# MEMORANDUM

To: Docket # EPA-HQ-OAR-2011-0512

From: Alexis McKittrick and Mark DeFigueiredo, EPA/CCD

Date: February 20, 2014

Subject: Data Category Assignments and Confidentiality Determinations for All Data

Elements (excluding inputs to emission e quations) in the Propos ed “Revisions and

Confidentiality Determinations for Petroleum and Natural Gas Systems”

In the proposed rulemaking titled “Revisions an d Confidentiality Determinations for Petroleum

and Natural Gas Systems (referred hereafter as the Subpart W 2014 Proposed Amendments), the

EPA is proposing revisions to the current subpart W reporting requirements. These revisions

include revisions to existing reporting requirements and the addition of several new data

elements. In conjunction with the proposed revisions, the EPA is proposing confidentiality

determinations for proposed new and substantially revised data elements (i.e., those that would

require additional or different da ta to be reported), except for t hose proposed to be assigned to

the inputs to emission equations data category. In this memorandum, we provide a list of all the

proposed new and substantially re vised data elements (excluding those proposed to be assigned

to the inputs to emission equations data categor y), the proposed confidentiality determinations,

and where appropriate, the data category assignments.

Table A-1 shows the proposed cate gory assignments for all new and substantially revised data

elements assigned to data categories for which a categorical confidentiality determination was

previously finalized in 2011. As explained in the preamble to the Subpart W 2014 Proposed

Amendments (“the preamble”), for data elements listed in Table A-1, the EPA is proposing to

apply the categorical determinati ons established in 2011. Descripti ons of these data categories,

the categorical confidentiality determinations made for these categories, and the rationale behind

those determinations are provided in preambl es to the proposed and final rulemakings:

“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” published on July 7, 2010 (75 FR 39094); and

“Confidentiality Determinations for Data Required under the Mandatory Greenhouse Gas

Reporting Rule and Amendment to Special Rules Governing Certain Information Obtained under

the Clean Air Act” published on May 26, 2011 (76 FR 30782). For discussion of the proposed

new and substantially revised data elements, their proposed category assignments, and the

proposed application of the categorical confiden tiality determinations, see Section III.B of the

preamble to the Subpart W 2014 Proposed Amendments.

# 2

Table A-2 shows the proposed categorical assignme nts and confidentiality determinations for all

new and substantially revised data elements assigned to the data categories “Unit/Process

‘Operating’ Characteristics That Are Not I nputs to Emission Equations” and “Unit/Process

‘Static’ Characteristics that Are Not Inputs to Emission Equations.” As explained in the

preamble to this proposed rulemaking, the EPA di d not establish categor ical confidentiality

determinations for these two data categories in 2011, and confidentiality determinations for data

elements assigned to these two data categories are made on a case-by-case basis for these data

elements, as explained in the preamble. See Sec tion III.C of the preamble to the Subpart W 2014

Proposed Amendments for more information on th e proposed new and substantially revised data

elements assigned to these two data categories, their proposed confidentiality determinations,

and the rationales for the determinations.

Table A-3 shows the proposed confidentiality dete rminations for 12 data elements. Eleven of

these are new data elements for which no categor ical assignment is proposed. The table also

includes the re-proposed confidentiality determin ation for one data element previously assigned

to the category “Production/Throughput Data that are Not Inputs to Emission Equations” and for

which EPA is proposing to remove the previous categorical assignment a nd application of the

categorical determination. For more informati on on these 12 proposed new data elements and

one existing revised data element, the proposed (or re-proposed) confidentiality determinations,

and rationale supporting the determinations, see Section III.D of the preamble to the Subpart W

2014 Proposed Amendments.

The Subpart W 2014 Proposed Amendments also in clude minor revisions to current subpart W

reporting requirements and several new data elements that are proposed to be assigned to the

inputs to emission equations da ta category. These data elements are not listed in this

memorandum. As explained in the preamble, the mi nor revisions consist of changes that clarify

existing reporting requirements and would not requi re reporting of different or additional data.

Therefore, no confidentiality determination is proposed in conjunction with these minor

revisions, and the previously established confidentiality determinations for these data elements

continue to apply. The proposed new inputs to emission equati ons are discussed in another

memorandum titled “Review of Potential Disclo sure Concerns for Proposed New Inputs to

Emission Equations in the Proposed Rulemaking ‘Revisions and Confiden tiality Determinations

for Petroleum and Natural Gas Systems.”
