Sec. 60.153 Monitoring of operations.
(a) The owner or operator of any sludge incinerator subject to the
provisions of this subpart shall:
(1) Install, calibrate, maintain, and operate a flow measuring
device which can be used to determine either the mass or volume of
sludge charged to the incinerator. The flow measuring device shall be
certified by the manufacturer to have an accuracy of 5 percent over its operating range. Except as provided
in paragraph (d) of this section, the flow measuring device shall be
operated continuously and data recorded during all periods of operation
of the incinerator.
(2) Provide access to the sludge charged so that a well-mixed
representative grab sample of the sludge can be obtained.
(3) Install, calibrate, maintain, and operate a weighing device for
determining the mass of any municipal solid waste charged to the
incinerator when sewage sludge and municipal solid waste are incinerated
together. The weighing device shall have an accuracy of 5 percent over its operating range.
(b) The owner or operator of any multiple hearth, fluidized bed, or
electric sludge incinerator subject to the provisions of this subpart
shall comply with the requirements of paragraph (a) of this section and:
(1) For incinerators equipped with a wet scrubbing device, install,
calibrate, maintain and operate a monitoring device that continuously
measures and records the pressure drop of the gas flow through the wet
scrubbing device. Where a combination of wet scrubbers is used in
series, the pressure drop of the gas flow through the combined system
shall be continuously monitored. The device used to monitor scrubber
pressure drop shall be certified by the manufacturer to be accurate
within 250 pascals (1 inch
water gauge) and shall be calibrated on an annual basis in accordance
with the manufacturer's instructions.
(2) Install, calibrate, maintain and operate a monitoring device
that continuously measures and records the oxygen content of the
incinerator exhaust gas. The oxygen monitor shall be located upstream of
any rabble shaft cooling air inlet into the incinerator exhaust gas
stream, fan, ambient air recirculation damper, or any other source of
dilution air. The oxygen monitoring device shall be certified by the
manufacturer to have a relative accurancy of 5
percent over its operating range and shall be calibrated according to
method(s) prescribed by the manufacturer at least once each 24-hour
operating period.
(3) Install, calibrate, maintain and operate temperature measuring
devices at every hearth in multiple hearth furnaces; in the bed and
outlet of fluidized bed incinerators; and in the drying, combustion, and
cooling zones of electric incinerators. For multiple hearth furnaces, a
minimum of one temperature measuring device shall be installed in each
hearth in the cooling and drying zones, and a minimum of two temperature
measuring devices shall be installed in each hearth in the combustion
zone. For electric incinerators, a minimum of one temperature measuring
device shall be installed in the drying zone and one in the cooling
zone, and a minimum of two temperature measuring devices shall be
installed in the combustion zone. Each temperature measuring device
shall be certified by the manufacturer to have an accuracy of 5 percent over its operating range. Except as provided
in paragraph (d) of this section, the temperature monitoring devices
shall be
[[Page 379]]
operated continuously and data recorded during all periods of operation
of the incinerator.
(4) Install, calibrate, maintain and operate a device for measuring
the fuel flow to the incinerator. The flow measuring device shall be
certified by the manufacturer to have an accuracy of 5 percent over its operating range. Except as provided
in paragraph (d) of the section, the fuel flow measuring device shall be
operated continuously and data recorded during all periods of operation
of the incinerator.
(5) Except as provided in paragraph (d) of this section, collect and
analyze a grab sample of the sludge fed to the incinerator once per day.
The dry sludge content and the volatile solids content of the sample
shall be determined in accordance with the method specified under Sec.
60.154(b)(5), except that the determination of volatile solids, step
(3)(b) of the method, may not be deleted.
(c) The owner or operator of any multiple hearth, fluidized bed, or
electric sludge incinerator subject to the provisions of this subpart
shall retain the following information and make it available for
inspection by the Administrator for a minimum of 2 years:
(1) For incinerators equipped with a wet scrubbing device, a record
of the measured pressure drop of the gas flow through the wet scrubbing
device, as required by paragraph (b)(1) of this section.
(2) A record of the measured oxygen content of the incinerator
exhaust gas, as required by paragraph (b)(2) of this section.
(3) A record of the rate of sludge charged to the incinerator, the
measured temperatures of the incinerator, the fuel flow to the
incinerator, and the total solids and volatile solids content of the
sludge charged to the incinerator, as required by paragraphs (a)(1),
(b)(3), (b)(4), and (b)(5) of this section.
(d) The owner or operator of any multiple hearth, fluidized bed, or
electric sludge incinerator subject to the provisions of this subpart
from which the particulate matter emission rate measured during the
performance test required under Sec. 60.154(d) is less than or equal to
0.38 g/kg of dry sludge input (0.75 lb/ton) shall be required to comply
with the requirements in paragraphs (a), (b), and (c) of this section
during all periods of this incinerator following the performance test
except that:
(1) Continuous operation of the monitoring devices and data
recorders in paragraphs (a)(1), (b)(3), and (b)(4) of this section shall
not be required.
(2) Daily sampling and analysis of sludge feed in paragraph (b)(5)
of this section shall not be required.
(3) Recordkeeping specified in paragraph (c)(3) of this section
shall not be required.
(e) 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 submit to the Administrator for approval a plan for monitoring and
recording incinerator and control device operation parameters. The plan
shall be submitted to the Administrator:
(1) No later than 90 days after October 6, 1988, for sources which
have provided notification of commencement of construction prior to
October 6, 1988.
(2) No later than 90 days after the notification of commencement of
construction, for sources which provide notification of commencement of
construction on or after October 6, 1988.
(3) At least 90 days prior to the date on which the new control
device becomes operative, for sources switching to a control device
other than a wet scrubber.
