The average dry sludge content shall be the arithmetic average of all the samples taken during the run. NR 440.32(5)(d)(d) The owner or operator of any sludge incinerator subject to the provisions of this section shall conduct a performance test during which the monitoring and recording devices required under sub. (4) (a) 1. and (b) 1. to 4., are installed and operating and for which the sampling and analysis procedures required under sub. (4) (b) 5. are performed. The owner or operator shall provide the department at least 30 days prior notice of the performance test to afford the department the opportunity to have an observer present. NR 440.32(5)(d)1.1. For incinerators that commenced construction or modification on or before April 18, 1986, the performance test shall be conducted by October 1, 1989 unless the monitoring and recording devices required under sub. (4) (a) 1. and (b) 1. to 4. were installed and operating and the sampling and analysis procedures required under sub. (4) (b) 5. were performed during the most recent performance test and a record of the measurements taken during the performance test is available. NR 440.32(5)(d)2.2. For incinerators that commence construction or modification after April 18, 1986, the date of the performance test shall be determined by the requirements in s. NR 440.08. NR 440.32(6)(a)(a) The owner or operator of any multiple hearth, fluidized bed or electric sludge incinerator subject to the provisions of this section shall submit to the department semiannually a report in writing which contains the following: NR 440.32(6)(a)1.1. A record of average scrubber pressure drop measurements for each period of 15 minute duration or more during which the pressure drop of the scrubber was less than, by a percentage specified in subd. 1. a. or b., as applicable, the average scrubber pressure drop measured during the most recent performance test. The percent reduction in scrubber pressure drop for which a report is required shall be determined as follows: NR 440.32(6)(a)1.a.a. For incinerators that achieved an average particulate matter emission rate of 0.38 kg/Mg (0.75 lb/ton) dry sludge input or less during the most recent performance test, a scrubber pressure drop reduction of more than 30% from the average scrubber pressure drop recorded during the most recent performance test shall be reported. NR 440.32(6)(a)1.b.b. For incinerators that achieved an average particulate matter emission rate of greater than 0.38 kg/Mg (0.75 lb/ton) dry sludge input during the most recent performance test, a percent reduction in pressure drop greater than that calculated according to the following equation shall be reported: P = - 111E + 72.15
where:
P is the percent reduction in pressure drop, and
E is the average particulate matter emissions (kg/megagram)
NR 440.32(6)(a)2.2. A record of average oxygen content in the incinerator exhaust gas for each period of 1-hour duration or more that the oxygen content of the incinerator exhaust gas exceeds the average oxygen content measured during the most recent performance test by more than 3%. NR 440.32(6)(b)(b) The owner or operator of any multiple hearth, fluidized bed or electric sludge incinerator from which the average particulate matter emission rate measured during the performance test required under sub. (5) (d) exceeds 0.38 g/kg of dry sludge input (0.75 lb/ton of dry sludge input) shall include in the report for each calendar day that a decrease in scrubber pressure drop or increase in oxygen content of exhaust gas is reported a record of the following: NR 440.32(6)(b)1.1. Scrubber pressure drop averaged over each 1-hour incinerator operating period. NR 440.32(6)(b)2.2. Oxygen content in the incinerator exhaust averaged over each 1-hour incinerator operating period. NR 440.32(6)(b)3.3. Temperatures of every hearth in multiple hearth incinerators; of the bed and outlet of fluidized bed incinerators; and of the drying, combustion and cooling zones of electric incinerators averaged over each 1-hour incinerator operating period. NR 440.32(6)(b)4.4. Rate of sludge charged to the incinerator averaged over each 1-hour incinerator operating period. NR 440.32(6)(b)5.5. Incinerator fuel use averaged over each 8-hour incinerator operating period. NR 440.32(6)(b)6.6. Moisture and volatile solids content of the daily grab sample of sludge charged to the incinerator. NR 440.32(6)(c)(c) The owner or operator of any sludge incinerator other than a multiple hearth, fluidized bed or electric incinerator or any sludge incinerator equipped with a control device other than a wet scrubber shall include in the semiannual report a record of control device operation measurements, as specified in the plan approved under sub. (4) (e). NR 440.32 HistoryHistory: Cr. Register, January, 1984, No. 337, eff. 2-1-84; am. (2) (intro.), Register, September, 1990, No. 417, eff. 10-1-90; am. (4) (a) 1., cr.
