40 CFR § 62.15280 - What minimum amount of monitoring data must I collect with my continuous parameter monitoring systems and is this requirement enforceable?
(a) Where continuous parameter monitoring systems are used, obtain 1-hour arithmetic averages for three parameters:
(1) Load level of the municipal waste combustion unit.
(3) Carbon feed rate if activated carbon is used to control dioxins/furans or mercury emissions.
(b) Obtain at least two data points per hour in order to calculate a valid 1-hour arithmetic average.
(c) Obtain valid 1-hour averages for at least 75 percent of the operating hours per day for 90 percent of the operating days per calendar quarter. An operating day is any day the unit combusts any municipal solid waste or refuse-derived fuel.
(d) If you do not obtain the minimum data required in paragraphs (a) through (c) of this section, you are in violation of this data collection requirement and you must notify the Administrator according to § 62.15340(e).
