Sec. 60.274a Monitoring of operations.
(a) The owner or operator subject to the provisions of this subpart
shall maintain records of the following information:
(1) All data obtained under paragraph (b) of this section; and
(2) All monthly operational status inspections performed under
paragraph (c) of this section.
(b) Except as provided under paragraph (e) of this section, the
owner or operator subject to the provisions of this subpart shall check
and record on a once-per-shift basis the furnace static pressure (if 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 position 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. 60.272a(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 affected
facility 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established are no longer applicable.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. 60.276a(c).
(d) Except as provided under paragraph (e) of this section, 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 holes 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.
(e) The owner or operator may petition the Administrator to approve
any alternative to either the monitoring requirements specified in
paragraph (b) of this section or the monthly operational status
inspections specified in paragraph (d) of this section if the
alternative will provide a continuous record of operation of each
emission capture system.
(f) Except as provided for under Sec. 60.273a(d), if emissions
during any phase of the heat time are controlled by the use of a DEC
system, the owner or operator shall install, calibrate, and maintain a
monitoring device that allows the pressure in the free space inside the
EAF to be monitored. The pressure shall be recorded as 15-minute
integrated averages. The monitoring
[[Page 416]]
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. 60.273a(d), when the owner or
operator of an EAF controlled by a DEC is required to demonstrate
compliance with the standard under Sec. 60.272a(a)(3), and at any other
time the Administrator may require (under section 114 of the Clean Air
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 required under paragraph (f) of this section. The
owner or operator may petition the Administrator for reestablishment of
the 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 when 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) During any performance test required under Sec. 60.8, and for
any report thereof required by Sec. 60.276a(f) of this subpart, or to
determine compliance with Sec. 60.272a(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 an EAF when direct-shell evacuation control systems are
used;
(3) Control device operation log; and
(4) Continuous opacity monitor or Method 9 data.
