Proposed Amended Rule 1118 – Control of Emissions from Refinery Flares

Rule 1118 was adopted to minimize emissions from flaring operations at petroleum refineries, sulfur recovery units, and hydrogen production plants that primarily supply hydrogen to refinery operations. Rule 1118 was most recently amended in 2024 to update monitoring, recordkeeping, and reporting requirements, as well as flare event notification requirements, amongst other edits. Proposed Amended Rule 1118 (PAR 1118) consists of administrative changes to: 1) replace the standard compliance date placeholder language in the monitoring, recordkeeping, and reporting requirements with a specific compliance date; and 2) clarify flare event notification requirements. While no emission reductions are expected, PAR 1118 will benefit stakeholders by providing improved clarity for implementing the applicable requirements.
