§98.66. Data reporting requirements.
40 C.F.R. § 98.66
In addition to the information required by § 98.3(c), you must report the following information at the facility level:
[Reserved]
Type of smelter technology used.
The following PFC-specific information on an annual basis—
Perfluoromethane emissions and perfluoroethane emissions from anode effects in all prebake and all Søderberg electrolysis cells combined.
Anode effect minutes per cell-day (AE-mins/cell-day), anode effect frequency (AE/cell-day), anode effect duration (minutes). (Or anode effect overvoltage factor ((kg CF4/metric ton Al)/(mV/cell day)), potline overvoltage (mV/cell day), current efficiency (%)).
Smelter-specific slope coefficients (or overvoltage emission factors) and the last date when the smelter-specific slope coefficients (or overvoltage emission factors) were measured.
Method used to measure the frequency and duration of anode effects (or overvoltage).
The following CO<I>2</I>-specific information for prebake cells—
Annual anode consumption if using the method in § 98.63(g).
Annual CO<I>2</I> emissions from the smelter.
The following CO<I>2</I>-specific information for Søderberg cells—
Annual paste consumption if using the method in § 98.63(g).
Annual CO<I>2</I> emissions from the smelter.
[Reserved]
Exact data elements required will vary depending on smelter technology (e.g., point-feed prebake or Søderberg) and process control technology (e.g., Pechiney or other).
