FROM: Lisa Grogan-McCulloch

SUBJECT: Final Data Elements Deferred to March 31, 2015: List of Data Elements Not 

To Be Reported

Table 1 lists the data elements for which reporting was deferred to March 31, 2015 that will not to be 

reported, as specified in the final rulemaking “Revisions to Reporting and Recordkeeping Requirements, 

and Confidentiality Determinations under the Greenhouse Gas Reporting Program.” 

Table 2 lists data elements for which reporting was deferred to March 31, 2015 that the EPA is not 

amending in this action, as specified in the final rulemaking, because there are no disclosure concerns 

based on the EPA’s analysis documented in “Final Evaluation of Competitive Harm from Disclosure of 

‘Inputs to Equations’ Data Elements Deferred to March 31, 2015,” September 2014. As a result, these 

data elements must be reported under the final rulemaking.

Though the “Final Evaluation of Competitive Harm” memorandum cited above includes analysis results 

for the inputs to emission equations in subpart L for which reporting was deferred to 2015, these subpart 

L inputs to emission equations are not included in Tables 1 or 2 of this memorandum because the EPA’s 

final decisions on the reporting of subpart L inputs will be addressed in a separate rulemaking.
