Sec. 60.274 Monitoring of operations.
(a) The owner or operator subject to the provisions of this subpart
shall maintain records daily of the following information:
(1) Time and duration of each charge;
(2) Time and duration of each tap;
(3) All flow rate data obtained under paragraph (b) of this section,
or equivalent obtained under paragraph (d) of this section; and
(4) All pressure data obtained under paragraph (f) of this section.
(b) Except as provided under paragraph (d) of this section, the
owner or operator subject to the provisions of this subpart shall check
and record on a once-per-shift basis furnace static pressure (if a DEC
system is in use, and a furnace static pressure gauge is installed
according to paragraph (f) of this section) and either: check and record
the control system fan motor amperes and damper positions on a once-per-
shift basis; install, calibrate, and maintain a monitoring device that
continuously records the volumetric flow rate through each separately
ducted hood; or install, calibrate, and maintain a monitoring device
that continuously records the volumetric flow rate at the control device
inlet and check and record damper positions on a once-per-shift basis.
The monitoring device(s) may be installed in any appropriate location in
the exhaust duct such that reproducible flow rate monitoring will
result. The flow rate monitoring device(s) shall have an accuracy of
10 percent over its normal operating range and
shall be calibrated according to the manufacturer's instructions. The
Administrator may require the owner or operator to demonstrate the
accuracy of the monitoring device(s) relative to Methods 1 and 2 of
appendix A of this part.
(c) When the owner or operator of an affected facility is required
to demonstrate compliance with the standards under Sec. 60.272(a)(3)
and at any other time that the Administrator may require (under section
114 of the CAA, as amended) either: the control system fan motor amperes
and all damper positions, the volumetric flow rate through each
separately ducted hood, or the volumetric flow rate at the control
device inlet and all damper positions

shall be determined during all periods in which a hood is operated for
the purpose of capturing emissions from the affected facility subject to
paragraph (b) of this section. The owner or operator may petition the
Administrator for reestablishment of these parameters whenever the owner
or operator can demonstrate to the Administrator's satisfaction that the
EAF operating conditions upon which the parameters were previously
established are no longer applicable. The values of these parameters as
determined during the most recent demonstration of compliance shall be
maintained at the appropriate level for each applicable period.
Operation at other than baseline values may be subject to the
requirements of Sec. 60.276(a).
(d) The owner or operator may petition the Administrator to approve
any alternative method that will provide a continuous record of
operation of each emission capture system.
(e) The owner or operator shall perform monthly operational status
inspections of the equipment that is important to the performance of the
total capture system (i.e., pressure sensors, dampers, and damper
switches). This inspection shall include observations of the physical
appearance of the equipment (e.g., presence of hole in ductwork or
hoods, flow constrictions caused by dents or accumulated dust in
ductwork, and fan erosion). Any deficiencies shall be noted and proper
maintenance performed.
(f) Except as provided for under Sec. 60.273(d), where emissions
during any phase of the heat time are controlled by use of a direct
shell evacuation system, the owner or operator shall install, calibrate,
and maintain a monitoring device that continuously records the pressure
in the free space inside the EAF. The pressure shall be recorded as 15-
minute integrated averages. The monitoring device may be installed in
any appropriate location in the EAF or DEC duct prior to the
introduction of ambient air such that reproducible results will be
obtained. The pressure monitoring device shall have an accuracy of
5 mm of water gauge over its normal operating
range and shall be calibrated according to the manufacturer's
instructions.
(g) Except as provided for under Sec. 60.273(d), when the owner or
operator of an EAF is required to demonstrate compliance with the
standard under Sec. 60.272(a)(3) and at any other time the
Administrator may require (under section 114 of the Act, as amended),
the pressure in the free space inside the furnace shall be determined
during the meltdown and refining period(s) using the monitoring device
under paragraph (f) of this section. The owner or operator may petition
the Administrator for reestablishment of the 15-minute integrated
average pressure whenever the owner or operator can demonstrate to the
Administrator's satisfaction that the EAF operating conditions upon
which the pressures were previously established are no longer
applicable. The pressure determined during the most recent demonstration
of compliance shall be maintained at all times the EAF is operating in a
meltdown and refining period. Operation at higher pressures may be
considered by the Administrator to be unacceptable operation and
maintenance of the affected facility.
(h) Where the capture system is designed and operated such that all
emissions are captured and ducted to a control device, the owner or
operator shall not be subject to the requirements of this section.
(i) During any performance test required under Sec. 60.8, and for
any report thereof required by Sec. 60.276(c) of this subpart or to
determine compliance with Sec. 60.272(a)(3) of this subpart, the owner
or operator shall monitor the following information for all heats
covered by the test:
(1) Charge weights and materials, and tap weights and materials;
(2) Heat times, including start and stop times, and a log of process
operation, including periods of no operation during testing and the
pressure inside the furnace where direct-shell evacuation systems are
used;
(3) Control device operation log; and
(4) Continuous opacity monitor or Method 9 data.
