**Greenhouse Gas Reporting Rule: Leak Detection Methodology Revisions and**  **Confidentiality Determinations for Petroleum and Natural Gas Systems** 

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Proposed rule.

**SUMMARY :**  The EPA is proposing revisions and confidentiality determinations for the petroleum and natural gas systems source category of the Greenhouse Gas Reporting Program (GHGRP).

The EPA is also proposing to add emission factors for leaking equipment to be used in conjunction with these monitoring methods to calculate and report greenhouse gas (GHG) emissions resulting from equipment leaks. Further, the EPA is proposing reporting requirements and confidentiality determinations for nine new or substantially revised data elements.
