Use comparable facility, pollutant and time boundaries.
Question / intended use:
Dataset / release version / download date / reporting year:
Plant name / identifier / location / unit or whole-plant boundary:
Pollutant / mass unit / generation unit / seasonal or annual period:
Year A mass / net MWh / rate:
Year B mass / net MWh / rate:
Output rate = mass in pounds / net generation in MWh.
U.S. short tons x 2,000 = pounds. Keep metric tonnes distinct.
Fictional A: 2,000,000 / 100,000 = 20 lb/MWh.
Fictional B: 1,500,000 / 50,000 = 30 lb/MWh.
Mass falls 25%; generation falls 50%; rate rises 50%.
For multiple plants: sum mass / sum generation.
Missing data / zero or negative generation / revisions:
Operational explanation and supporting record:
Regional inventory method, if applicable:
Ambient monitoring or compliance evidence needed:
