Sec. 60.265  Monitoring of operations.

    (a) The owner or operator of any electric submerged arc furnace 
subject to the provisions of this subpart shall maintain daily records 
of the following information:
    (1) Product being produced.
    (2) Description of constituents of furnace charge, including the 
quantity, by weight.
    (3) Time and duration of each tapping period and the identification 
of material tapped (slag or product.)
    (4) All furnace power input data obtained under paragraph (b) of 
this section.
    (5) All flow rate data obtained under paragraph (c) of this section 
or all fan motor power consumption and pressure drop data obtained under 
paragraph (e) of this section.
    (b) The owner or operator subject to the provisions of this subpart 
shall install, calibrate, maintain, and operate a device to measure and 
continuously record the furnace power input. The furnace power input may 
be measured at the output or input side of the transformer. The device 
must have an accuracy of 5 percent over its 
operating range.
    (c) The owner or operator subject to the provisions of this subpart 
shall install, calibrate, and maintain a monitoring device that 
continuously measures and records the volumetric flow rate through each 
separately ducted hood of the capture system, except as provided under 
paragraph (e) of this section. The owner or operator of an electric 
submerged arc furnace that is equipped with a water cooled cover which 
is designed to contain and prevent escape of the generated gas and 
particulate matter shall monitor only the volumetric flow rate through 
the capture system for control of emissions from the tapping station. 
The owner or operator may install the monitoring device(s) in any 
appropriate location in the exhaust duct such that reproducible flow 
rate monitoring will result. The flow rate monitoring device must have 
an accuracy of 10 percent over its normal 
operating range and must be calibrated according to the manufacturer's 
instructions. The Administrator may require the owner or operator to 
demonstrate the accuracy of the monitoring device relative to Methods 1 
and 2 of appendix A to this part.

    (d) When performance tests are conducted under the provisions of 
Sec. 60.8 of this part to demonstrate compliance with the standards 
under Sec. Sec. 60.262(a) (4) and (5), the volumetric flow rate through 
each separately ducted hood of the capture system must be determined 
using the monitoring device required under paragraph (c) of this 
section. The volumetric flow rates must be determined for furnace power 
input levels at 50 and 100 percent of the nominal rated capacity of the 
electric submerged arc furnace. At all times the electric submerged arc 
furnace is operated, the owner or operator shall maintain the volumetric 
flow rate at or above the appropriate levels for that furnace power 
input level determined during the most recent performance test. If 
emissions due to tapping are captured and ducted separately from 
emissions of the electric submerged arc furnace, during each tapping 
period the owner or operator shall maintain the exhaust flow rates 
through the capture system over the tapping station at or above the 
levels established during the most recent performance test. Operation at 
lower flow rates may be considered by the Administrator to be 
unacceptable operation and maintenance of the affected facility. The 
owner or operator may request that these flow rates be reestablished by 
conducting new performance tests under Sec. 60.8 of this part.
    (e) The owner or operator may as an alternative to paragraph (c) of 
this section determine the volumetric flow rate through each fan of the 
capture system from the fan power consumption, pressure drop across the 
fan and the fan performance curve. Only data specific to the operation 
of the affected electric submerged arc furnace are acceptable for 
demonstration of compliance with the requirements of this paragraph. The 
owner or operator shall maintain on file a permanent record of the fan 
performance curve (prepared for a specific temperature) and shall:
    (1) Install, calibrate, maintain, and operate a device to 
continuously measure and record the power consumption of the fan motor 
(measured in kilowatts), and
    (2) Install, calibrate, maintain, and operate a device to 
continuously measure and record the pressure drop across the fan. The 
fan power consumption and pressure drop measurements must be 
synchronized to allow real time comparisions of the data. The monitoring 
devices must have an accuracy of 5 percent over 
their normal operating ranges.
    (f) The volumetric flow rate through each fan of the capture system 
must be determined from the fan power consumption, fan pressure drop, 
and fan performance curve specified under paragraph (e) of this section, 
during any performance test required under Sec. 60.8 to demonstrate 
compliance with the standards under Sec. Sec. 60.262(a)(4) and (5). The 
owner or operator shall determine the volumetric flow rate at a 
representative temperature for furnace power input levels of 50 and 100 
percent of the nominal rated capacity of the electric submerged arc 
furnace. At all times the electric submerged arc furnace is operated, 
the owner or operator shall maintain the fan power consumption and fan 
pressure drop at levels such that the volumetric flow rate is at or 
above the levels established during the most recent performance test for 
that furnace power input level. If emissions due to tapping are captured 
and ducted separately from emissions of the electric submerged arc 
furnace, during each tapping period the owner or operator shall maintain 
the fan power consumption and fan pressure drop at levels such that the 
volumetric flow rate is at or above the levels established during the 
most recent performance test. Operation at lower flow rates may be 
considered by the Administrator to be unacceptable operation and 
maintenance of the affected facility. The owner or operator may request 
that these flow rates be reestablished by conducting new performance 
tests under Sec. 60.8. The Administrator may require the owner or 
operator to verify the fan performance curve by monitoring necessary fan 
operating parameters and determining the gas volume moved relative to 
Methods 1 and 2 of appendix A to this part.
    (g) All monitoring devices required under paragraphs (c) and (e) of 
this section are to be checked for calibration annually in accordance 
with the procedures under Sec. 60.13(b).
