N.H. Admin. Code § Env-A 3102.02
"Actual emissions rate" means "actual emissions rate" as defined in the US EPA's proposed Model Open Market Trading Rule (60 FR 39668, August 3, 1995), namely, "the actual rate of emissions of a pollutant from a Source. Actual emissions as of a particular date shall equal the average rate, in mass per unit of time or mass per unit of activity, at which the unit actually emitted the pollutant during a two-year period which precedes the particular date and which is representative of normal source operation at a particular time. A different time period may be used if that is more representative of normal source operation. Actual emissions shall be calculated using the unit's actual operating hours, production rates, types of materials processed, stored, or combusted during the selected time period."
