• Flare stack emissions, as calculated under §98.233(n), are a reportable source for Onshore Petroleum and Natural Gas Production facilities and Natural Gas Processing facilities, per §98.232(c)(9) and §98.232(d)(6), respectively
• Source-specific "vented “vented to flare" flare” emissions reporting; as specified in §98.236 for dehydrators, gas well completions and workovers, gas from produced oil sent to atmospheric tanks, transmission tanks, well testing, associated gas venting and flaring, centrifugal compressors, and reciprocating compressors; and
• For Offshore Petroleum and Natural Gas Production facilities, per §98.236(b) emissions from flares are reported separately on the Offshore Emission Source tab.

...

1. If emissions are reported under a source-specific "vented “vented to flare" flare” reporting category, as list above, those specific emissions should be reported under that source and not reported elsewhere in the facility's facility’s annual GHG reporting.
2. Flare stack emission at Onshore Petroleum and Natural Gas Production facilities and Natural Gas Processing facilities that are not captured under (1) should be reported under the flare stack emission per §98.233(n). To the extent that monitoring information includes amounts associated with reported emission under (1), those emissions should be deducted from the total emissions reported according to the methods in §98.233(n).

• Unique name or ID number for the flare stack (98.236(c)(12)(x)) - this data element is only required for Onshore Natural Gas Processing facilities
• Does the flare have a continuous flow monitor? (Yes or No) (98.236(c)(12)(i))
• Percent of gas sent to un-lit flare determine by engineering estimate and process knowledge based on best available data and operating records (98.236(c)(12)(iii))
• Does the flare have a continuous gas analyzer? (Yes or No) (98.236(c)(12)(iv))
• Were CEMS used to measure CO2 emissions for the flare stack? (Yes or No) (98.236(c)(12)(xi))
  • If Yes, the facility must report:
    • If CEMS were used, combusted and uncombusted CO2 (98.236(c)(12)(iii))
    • Do not report data for the remaining fields
  • If No, the facility must report:
    • Uncombusted CO2 emissions (98.236(c)(12)(vii))
    • Uncombusted CH4 emissions (98.236(c)(12)(vi))
    • Combusted CO2 emissions (98.236(c)(12)(viii))
    • N2O emissions (98.236(c)(12)(ix))
    • Do not report data for "If CEMS were used, combusted and uncombusted CO2"
