I. Background

On October 30, 2009, EPA published the Mandatory Greenhouse Gas

(GHG) Reporting Rule for collecting information regarding GHGs from a broad range of industry sectors (74 FR 56260). Under 40 CFR part 98 of the GHG Reporting Rule (hereinafter referred to as ``Part 98'') and its subsequent amendments, EPA will collect data from certain facilities and suppliers above specified thresholds. The data to be reported consists of GHG emissions information as well as other data, including information necessary to characterize, quantify, and verify the reported emissions. In the preamble to Part 98, we stated, ``Through a notice and comment process, we will establish those data elements that are `emissions data' and therefore [under CAA section

Page 81367

114(c)] will not be afforded the protections of CBI. As part of that exercise, in response to requests provided in comments, we may identify classes of information that are not emissions data, and are CBI'' (74

FR 56287, October 30, 2009).

On July 7, 2010, EPA proposed confidentiality determinations for

Part 98 data elements and proposed amending EPA's regulation for handling confidential business information to add specific procedures for the treatment of Part 98 data (75 FR 39094; hereinafter referred to as the ``July 7, 2010 CBI proposal''). The July 7, 2010 CBI proposal proposed confidentiality statuses for the data elements for subparts included in the 2009 final Part 98 rule (see 74 FR 56260, October 30, 2009), four subparts finalized in July 2010 (see 75 FR 39736, July 12, 2010), and seven new subparts that had been proposed but not yet finalized as of July 2010 (see 75 FR 18576, 75 FR 18608, and 75 FR 18652, April 12, 2010). The July 7, 2010 CBI proposal also covered proposed changes to the reporting requirements for some of the 2009 final Part 98 subparts. These changes were proposed in two separate rulemakings (see 75 FR 18455, April, 12, 2010; and 75 FR 33950, June 15, 2010).

On August 11, 2010, EPA published a proposed amendment to Part 98 to change the description of some reported data elements and require reporting of some new data elements (75 FR 48744; hereinafter referred to as the ``August 11, 2010 revisions proposal''). EPA concurrently issued a supplemental CBI proposal that proposed confidentiality determinations for the new and revised data elements included in the

August 11, 2010 revisions notice (75 FR 43889, July 27, 2010; hereinafter referred to as the ``July 27, 2010 supplemental CBI proposal.)''

As described in detail in the CBI proposals identified above, EPA grouped Part 98 data into 22 data categories (11 direct emitter data categories and 11 supplier data categories), with each of the categories containing data elements that are similar in type or characteristics. EPA then proposed confidentiality determinations for each category, with a few exceptions that are not relevant to today's action. Consistent with EPA's long-standing interpretation, EPA proposed that data elements in the inputs to emission equations data category meet the definition of emission data under 40 CFR 2.301(a)(2)(i) and therefore, under CAA section 114(c), could not be held as confidential once they were reported to EPA.

EPA received numerous public comments on the July 7, 2010 CBI proposal and the July 27, 2010 supplemental CBI proposal. Though we are still in the process of considering these comments, we plan to complete our consideration of these comments and issue final confidentiality determinations for the Part 98 data elements that are not inputs to emission equations, which constitute approximately 75 percent of the data elements, in a separate final action.

However, EPA received comments that raise concerns regarding the public availability of data in the inputs to emission equations category. Almost all commenters from industry wrote that some or all inputs to emission equations (which include product compositions, raw materials used, fuel types and quantities, production volumes, and other process-specific information) are considered trade secrets or otherwise sensitive business information, and that making that information publicly available would cause them serious competitive harm. Some commenters expressed concern that public disclosure of production volumes and process-specific information could give competitors insight into sensitive operational limits and process capabilities. The commenters explained that, combined with other publicly available information, this information could give competitors details concerning business positions or vulnerabilities that could be used to a reporter's disadvantage. Some commenters stated that disclosure of the type, composition, and relative proportions of raw materials used would reveal the specific formula used to manufacture their products. Others expressed concern that product composition data reveal information about their products' performance characteristics.

Some stated that public availability of information about the types and quantities of fuels consumed would reveal sensitive details about individual production processes' energy usage and could be used to estimate relative production costs.

Several Part 98 reporters commented that, had they known that EPA would later propose that inputs to emission equations qualify as emission data that must be made available to the public under CAA section 114(c), they would have commented more critically and more extensively on Part 98 equations when they were proposed in 2009 and might have suggested or agreed to alternatives such as third-party audits or installation of continuous emission monitoring systems

(CEMS). Several reporters wrote that they would have installed CEMS or otherwise changed their compliance approaches. Commenters further noted that, for some subparts, Part 98 allows monitoring emissions with CEMS as an alternative to calculation with emission equations but that, by the time EPA proposed CBI determinations in July 2010, reporters no longer could install CEMS for 2010. As a result, commenters stated, these reporters were locked into using the emission equations for 2010 reporting if that was the methodology they chose. They argued that public availability of potentially sensitive inputs for calculation of 2010 emissions should not be based on a reporter's decision not to install CEMS for 2010 when this decision was made prior to and without knowledge of the July 7, 2010 CBI proposal.

EPA has reviewed these comments and has concluded that some of the concerns warrant more extensive evaluation of potential harm from the public availability of inputs to equations. To assist EPA in this evaluation, EPA is issuing this notice to call for certain additional information that the Agency has determined is necessary or helpful in order to evaluate and take action on the concerns described above.

To allow EPA time to complete our evaluation and take appropriate actions before collecting inputs to equations, EPA is proposing in a separate notice to defer to March 31, 2014 the deadline for reporting inputs to equations. EPA is also concurrently promulgating an interim final rule that defers the reporting deadline for inputs to equations to August 31, 2011. This short-term deferral allows EPA time to complete the notice and comment rulemaking for the longer deferral while avoiding possible public availability of inputs to equations before EPA can evaluate and take appropriate actions regarding inputs to equations.

II. What is this action?

EPA is soliciting information and viewpoints from interested parties on how, specifically, public availability of inputs to emission equations in Part 98 could cause competitive harm. We are also interested in information on additional approaches to calculating GHG emissions that do not use data elements that may be considered sensitive and on additional approaches to verifying reported GHG emission data if any inputs to emission equations are not reported to

EPA. In addition, we are soliciting information on whether any of the inputs to emission equations data elements are already published or publicly available elsewhere,

Page 81368

discernable from publicly available information or otherwise not sensitive. The specific information requested is listed in Section III of this call for information.

This call for information is a critical part of EPA's consideration of treatment of inputs. If reporters have serious concerns about inputs to equations information becoming publicly available, it is crucial that they respond in a detailed fashion to this call for information.

The specific information received will help EPA to develop a sound, long-term approach that balances data quality and transparency with the need to protect sensitive business information. When EPA receives the additional requested information, we will be able to fully evaluate which inputs to equations, if any, could result in serious business harms if made available to the public. For such cases, if any, EPA would evaluate whether emissions can be calculated or verified using additional methodologies, consistent with the transparency and accuracy goals of Part 98. Should EPA identify any such additional methodologies, EPA may propose to amend Part 98 to allow these additional emission measurement or calculation approaches. If additional approaches to calculate or verify emissions are viable, EPA may decide that it is not necessary to collect certain highly sensitive inputs and propose to amend Part 98 accordingly.

As stated in the July 7, 2010 CBI proposal preamble, EPA is committed to transparency in the GHG Reporting Program. We consider transparency important because it promotes public confidence in the data and enables the public, industry, NGOs, and other stakeholders to better understand the sources of GHG emissions and the factors that affect the quantities of GHGs emitted. Any approach we adopt will be based on a well-balanced consideration of both the importance of protecting certain highly sensitive data elements and our commitment to the GHG Reporting Program's transparency and accuracy. Should EPA decide that it is necessary to amend Part 98 as a result of this evaluation, we would promulgate any such amendment through a notice and comment process.

III. What specific information is EPA seeking?

Although a few commenters on the July 7, 2010 CBI proposal identified specific data elements and provided supporting rationale regarding how the public availability of individual data elements would cause harm to their competitive positions, many provided only general statements that inputs to emission equations can be sensitive and should be held confidential. Other commenters noted that inputs to emission equations that reporters allege to be sensitive may already be publicly available, but did not identify specific data elements and where they are published. To enable us to better understand and evaluate stakeholder concerns and assertions, EPA requests from interested parties information and views on the following topics and questions:

Specific information identifying how public availability of any inputs to emission equations data elements would cause harm to any reporter.

--The identity of specific data elements used as inputs to emission equations that you consider sensitive business information that would cause competitive harm if disclosed. To better assist us in identifying the data element, include the rule citation for each data element you identify.

--For each data element identified in the above bullet, you should provide a specific explanation of how disclosure of the data would cause competitive harm. Describe the measures currently taken to keep the data confidential. If your concern is that competitors could use a particular input to discern sensitive information, specifically describe the pathway by which this could occur and explain how the discerned information would negatively affect your competitive position. Discuss how this data element may differ from similar data that is already publicly available. Describe any unique process or aspect of your facility that would be revealed if the particular data element you consider sensitive were made publicly available. If the data element you identify would cause harm only when used in combination with other publicly available data, then describe the other data, identify the public source(s) of this data, and explain how the combination of data could be used to cause competitive harm. Please be as specific as possible in your responses and include all information necessary to evaluate your assertions.

Which, if any, data that are inputs to emission equations are already publicly available, discernable from other publicly available data, or otherwise not sensitive for any reporter.

--In your response, please identify the manner and location in which each specific data element you identify is available or not sensitive, including a citation. If the data are physically published, such as in a book, industry trade publication, or Federal agency publication, provide the title, volume number (if applicable), author(s), publisher, publication date, and ISBN or other identifier. For data published on a Web site, provide the address of the Web site and identify the Web site publisher and content author.

Additional calculation or measurement approaches for a particular subpart that would comparably measure or calculate GHG emissions but would not use data elements that you consider to be sensitive as inputs to emission equations.

--Please provide full equations and describe your suggested calculation and/or measurement approach in detail. Describe the parameters used as inputs and explain how each input parameter could be measured. Indicate whether the measurement devices needed already exist or whether new measuring equipment would have to be installed and the time required for such installation. Compare the accuracy and cost of your proposed approach with those of the existing Part 98 approaches and describe any unique or unusual facility-specific situations in which your recommended approach would not provide accurate estimates of GHG emissions.

Verification approaches that could be used to verify emission figures and that would not require reporting to EPA the specific data elements you consider sensitive.

--Under the existing Part 98 rule, EPA will use the inputs to emissions equations to verify reported GHG emissions. EPA solicits suggestions for additional approaches for verifying the GHG emissions for facilities that use the existing Part 98 emission equations. In addition, we seek suggestions for verifying, without reporting to EPA, sensitive inputs to emissions equations. Identify any additional parameters that could be used for verification and the particular subpart that would be affected and explain how they would be used. Describe any particular situations in which your suggested approach should or should not be used.

EPA strongly urges any parties concerned about the public availability of inputs to equations to submit in detail the information requested above. If EPA is to seriously consider potentially revising the requirements of Part 98, the agency must have robust data on which to base those revisions. Conclusory or unsubstantiated statements will not suffice.

Please note that we are not requesting additional comment on EPA's proposed determination in the CBI proposals described above that inputs to emission equations constitute emission data. EPA received comment on that proposed determination during the public comment period for the

CBI proposals and will respond to those comments in a future action.
