In addition to the information required by §98.3(c), you must report the following information at the facility level:
(a) [Reserved]
(b) Type of smelter technology used.
(c) The following PFC-specific information on an annual basis:
(1) Perfluoromethane emissions and perfluoroethane emissions from anode effects in all prebake and all Søderberg electrolysis cells combined.
(2) 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 (%)).
(3) Smelter-specific slope coefficients (or overvoltage emission factors) and the last date when the smelter-specific slope coefficients (or overvoltage emission factors) were measured.
(d) Method used to measure the frequency and duration of anode effects (or overvoltage).
(e) The following CO2-specific information for prebake cells:
(1) Annual anode consumption if using the method in §98.63(g).
(2) Annual CO2 emissions from the smelter.
(f) The following CO2-specific information for Søderberg cells:
(1) Annual paste consumption if using the method in §98.63(g).
(2) Annual CO2 emissions from the smelter.
(g) [Reserved]
(h) 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).
