# MEMORANDUM

TO: Docket ID No. EPA-HQ-OAR-2014-0831

FROM: Alexis McKittrick and Mark de Figueiredo, EPA/CCD

DATE: September 23, 2015

SUBJECT: Data Category Assignments and Confidentiality Dete rminations for All Data

Elements (excluding inputs to emission equations) i n the Final “2015 Revisions

and Confidentiality Determinations for Petroleum an d Natural Gas Systems”

In the rulemaking titled “2015 Revisions and Confid entiality Determinations for

Petroleum and Natural Gas Systems” (referred hereaf ter as the Subpart W 2015 Amendments),

the EPA is finalizing revisions to the current subp art W reporting requirements. These revisions

include the addition of reporting requirements for two new industry segments (onshore

petroleum and natural gas gathering and boosting an d onshore natural gas transmission pipeline),

and the addition of reporting requirements for emis sions from hydraulically fractured oil wells

and for well identification numbers in the onshore petroleum and natural gas production industry

segment. The additions to the reporting requirement s would involve revisions to existing

reporting requirements and the addition of new data elements. In conjunction with the revisions,

the EPA is finalizing confidentiality determination s for the new data elements. In this

memorandum, we provide a list of all the new data e lements (excluding those assigned to the

“Inputs to Emission Equations” data category), the confidentiality determinations, and where

appropriate, the data category assignments.

Table 1 shows the category assignments for all new data elements assigned to data

categories for which a categorical confidentiality determination was previously finalized in

2011. 1 

# The categorical confidentiality determinations est ablished in 2011 apply to the data

elements listed in this table.

Table 2 shows the finalized categorical assignments and confidentiality determinations

for all new data elements assigned to the data cate gories “Unit/Process Operating Characteristics

That Are Not Inputs to Emission Equations” and “Uni t/Process ‘Static’ Characteristics that Are

Not Inputs to Emission Equations.” For the data ele ments listed in this table, the EPA is

# See “Proposed Confidentiality Determinations for D ata Required Under the Mandatory Greenhouse Gas Rep orting

Rule and Proposed Amendment to Special Rules Govern ing Certain Information Obtained Under the Clean Ai r Act”

published on July 7, 2010 (75 FR 39094); and “Confi dentiality Determinations for Data Required under t he

Mandatory Greenhouse Gas Reporting Rule and Amendme nt to Special Rules Governing Certain Information

Obtained under the Clean Air Act” published on May 26, 2011 (76 FR 30782).

# 2

finalizing confidentiality determinations based on a case-by-case review for each listed data

element.

Table 3 shows the final confidentiality determinati ons for six new data elements for

which no categorical assignment was proposed.

The Subpart W 2015 Amendments also include new subp art W reporting requirements

assigned to the “Inputs to Emission Equations” data category. For a list of the inputs to emission

equations, see the memorandum titled “Review for Po tential Disclosure Concerns for Inputs to

Emission Equations Affected by the ‘2015 Revisions and Confidentiality Determinations for

Petroleum and Natural Gas Systems.’” We determined that three data elements are inputs only in

certain situations (§98.236(g)(5)(i), §98.236(i)(1) (i) and §98.236(j)(3)(ii)). Specifically, these

data elements are inputs when the applicable data a re available for only one well, one blowdown,

or one gas-liquid separator. For situations when th ese data elements are not inputs ( i.e. , when

data are available for multiple wells, blowdowns, o r gas-liquid separators), the confidentiality

determinations noted in this memorandum apply.

CBI rules identified in this memorandum are availab le on EPA’s website:
