For municipal waste combustion units that use activated carbon to control dioxins/furans or mercury emissions, you must keep records of five items:
- (a)Records of average carbon feed rate. Document five items:
- (1)Average carbon feed rate (in kilograms or pounds per hour) during all stack tests for dioxins/furans and mercury emissions. Include supporting calculations in the records.
- (2)For the operating parameter chosen to monitor carbon feed rate, average operating level during all stack tests for dioxins/furans and mercury emissions. Include supporting data that document the relationship between the operating parameter and the carbon feed rate.
- (3)All 8-hour block average carbon feed rates in kilograms (pounds) per hour calculated from the monitored operating parameter.
- (4)Total carbon purchased and delivered to the municipal waste combustion plant for each calendar quarter. If you choose to evaluate total carbon purchased and delivered on a municipal waste combustion unit basis, record the total carbon purchased and delivered for each individual municipal waste combustion unit at your plant. Include supporting documentation.
- (5)Required quarterly usage of carbon for the municipal waste combustion plant, calculated using the appropriate equation in § 62.15390(f). If you choose to evaluate required quarterly usage for carbon on a municipal waste combustion unit basis, record the required quarterly usage for each municipal waste combustion unit at your plant. Include supporting calculations.
- (b)Records of low carbon feed rates. Document three items:
- (1)The calendar dates when the average carbon feed rate over an 8-hour block was less than the average carbon feed rates determined during the most recent stack test for dioxins/furans or mercury emissions (whichever has a higher feed rate).
- (2)Reasons for the low carbon feed rates.
- (3)Corrective actions you took or are taking to meet the 8-hour average carbon feed rate requirement.
- (c)Records of minimum carbon feed rate data. Document three items:
- (1)Calendar dates for which you did not collect the minimum amount of carbon feed rate data required under § 62.15280.
- (2)Reasons you did not collect the minimum data.
- (3)Corrective actions you took or are taking to get the required amount of data.
- (d)Records of exclusions. Document each time you have excluded data from your calculation of average carbon feed rates and the reasons the data were excluded.
- (e)Records of calendar dates. Include the calendar date on each record.
