- Q586. For Equation W-20, to calculate CO2 emissions from flares, do you use "5" for Rj (number of carbon atoms) for hydrocarbons with more than 5 carbons?
- Q587. Was it an oversight to not allow use of a CEMS as a quantification method on flares in §98.233(n )?
- Q588. Are flare emissions included in 40 CFR 98.2(a)(3)(iii) combined emissions from all stationary fuel combustion sources when determining applicability for Subpart W per 40 CFR 98.231(a)?
- Q589. Does associated gas flared only when an equipment disruption occurs fall under 98.233(m) or 98.233(n )?
- Q590. Why does EPA specify that reporters should subtract out volumes sent to flares to account for the portions of gas routed from dehys, completions and workovers?
- Q591. For a facility without a continuous gas composition analyzer, how is flare gas composition to be determined for use in Equations W-19 through W-21 if the gas stream includes gases from both upstream and downstream of the demethanizer?
- Q592. How is the composition for flare gas calculations determined if using a continuous analyzer (e.g., annual average)?
- Q593. Emissions from flares are specifically excluded under 98.232(e) but methods for these emissions are provided in 98.233. Can you clarify which section of the rule is the correct guiding action?
- Q594. Is flare combustion reported separately?
- Q595. Does a simple open pipe with no flare tip count as a flare under 40 CFR 98.233(n) in Subpart W?
- Q596. For flares at onshore natural gas production facilities, should CO2, CH4 and N2O be reported, while at onshore natural gas processing facilities, should only CO2 and CH4 should be reported?
- Q597. Are facilities in the onshore petroleum and natural gas production and natural gas processing industry segments required to report emissions from all of their flares, including emergency flares?
- Q598. In 98.33(n )(8), should the N2O emissions be multiplied by the GWP for N2O similar to the procedure in paragraph (n )(6) for CO2 and CH4 then added to the total CO2e amounts for CO2 and CH4 as suggested in paragraph (n )(7)?
- Q599. Was it an oversight to not allow use of a CEMS as a quantification method on flares?
