This page provides an overview of the Subpart W onshore petroleum and natural gas production and natural gas distribution combustion emissions source category e-GGRT reporting requirements.

The onshore petroleum and natural gas production and natural gas distribution combustion emissions source category is applicable to Onshore Petroleum and Natural Gas Production and Natural Gas Distribution.

Please refer to FAQ 667 for further information on the applicability of combustion emissions at Subpart W facilities.

Indicate if the facility has the source type via the radio buttons.

• If the source type is present you must report required emissions.

If the facility has the source type, the Best Available Monitoring Methods and Missing Data table must be completed.

• For further information, see Best Available Monitoring Methods and Missing Data Reporting.

Total Emissions

The total emissions roll-up at the top of the sheet reflects the sum of the CO₂ equivalents of each gas emission reported for the source type.  These summations are reflected and aggregated on the Introduction tab.
