Other - Acid Gas Removal Units

• Q542. Can EPA clarify the flow rates and conditions required to be reported in 40 CFR 98.236(d) for acid gas removal units?
• Q543. For acid gas removal vents using Calculation Method 3 (40 CFR 98.233(d)(3), are we allowed to make the conservative assumption that volume fraction of CO2 content in natural gas out of the AGR unit is zero?
• Q544. Do acid gas removal units which are used only to sweeten a liquid stream meet the definition of acid gas removal units?
• Q545. If all of the emissions from an AGR unit are recovered and transferred outside of the facility, does the facility still need to calculate emissions pursuant to Section 98.233(d)(11) and then "reduce" the emission to zero?
• Q546. Can facilities performing on-site acid gas injection estimate their emissions downward according to the provisions in 40 CFR 98.233(d)(11)?
• Q548. For Acid Gas Removal (AGR) vents is the use of a meter to measure flow rates required?
• Q553. When using Calculation Method 2 to calculate vented CO2 emissions from an AGR unit (Equation W-3), what are the required units of measure for the calculated CO2 emissions? May we use a flow meter to calculate annual emissions of CO2?
