My site has a gas collection system, which equations do I need to calculate to determine my methane generation and GHG emissions?
For landfills that have gas collection systems, you must calculate methane generation using both equations HH–5 and HH–7. If either equation shows that the landfill has methane generation ≥25,000 metric tons CO2e, then the landfill is required to report under the rule. If the landfill is required to report, than emissions must be calculated and reported using both equations HH–6 and HH–8.
