ACTION: Proposed rule.
SUMMARY: The EPA is proposing revisions and confidentiality determinations for the
petroleum and natural gas systems source category and the general provisions of the Greenhouse
Gas Reporting Rule. In particular, the EPA is proposing to revise certain calculation methods,
amend certain monitoring and data reporting requirements, clarify certain terms and definitions,
and correct certain technical and editorial errors that have been identified during the course of
implementation. This action also proposes confidentiality determinations for new or substantially
revised data elements contained in these proposed amendments, as well as proposes a revised
confidentiality determination for one existing data element.
