Sec. 9.
(a) The owner
or operator of a secondary lead smelter shall install and continuously operate
a bag leak detection system for all baghouses controlling process vents and
process fugitive emissions sources unless a system meeting the requirements of
section 10(g) of this rule for a CEMS is installed for monitoring the
concentration of lead. Baghouses equipped with HEPA filters or baghouses
followed by wet electrostatic precipitators used as secondary control devices
are exempt from this requirement. The owner or operator of a secondary lead
smelter shall maintain and operate each baghouse controlling process vents and
process fugitive emissions sources to meet the following conditions:
(1) The alarm on the system does not activate
for more than five percent (5%) of the total operating time in a six (6) month
reporting period.
(2) The owner or
operator of a secondary lead smelter shall include a corrective action plan in
its standard operating procedures manual required in subsection (c) that
specifies the procedures that will be used to determine and record the time and
cause of the alarm in addition to necessary corrective actions taken to
minimize emissions as follows:
(A) The
procedures used to determine the cause of the alarm shall be initiated within
thirty (30) minutes of the alarm.
(B) Procedures to determine and correct the
cause of the alarm may include, but are not limited to, the following standard
operating procedures:
(i) Inspecting the
baghouse for air leaks, torn or broken filter elements, or any other
malfunction that may cause an increase in emissions.
(ii) Sealing off defective bags or filter
media.
(iii) Replacing defective
bags or filter media, or otherwise repairing the control device.
(iv) Sealing off a defective baghouse
compartment.
(v) Cleaning the bag
leak detection system probe, or otherwise repairing the bag leak detection
system.
(vi) Shutting down the
process producing the particulate emissions.
(b) The owner or operator of a
secondary lead smelter shall demonstrate compliance with the bag leak detection
system requirements by submitting reports showing that the alarm on the system
does not activate for more than five percent (5%) of the total operating time
in a six (6) month period or two hundred nineteen (219) hours, if operated for
four thousand three hundred eighty (4,380) hours in the six (6) month period,
whichever is less.
(c) The owner
or operator of a secondary lead smelter shall calculate the percentage of total
operating time the alarm on the bag leak detection system activates as the
ratio of the sum of alarm times to the total operating time multiplied by one
hundred (100).
(d) The owner or
operator of a secondary lead smelter shall prepare and at all times operate in
accordance with a standard operating procedures manual that describes in detail
procedures for inspection, maintenance, and bag leak detection, and corrective
action plans for all baghouses (fabric filters or cartridge filters) that are
used to control process vents, process fugitive, or fugitive dust emissions
from any source subject to the lead emission standards in sections 3, 4, 5, 6,
and 8 of this rule, including those used to control emissions from building
ventilation.
(e) The owner or
operator of a secondary lead smelter shall submit the standard operating
procedures manual for baghouses required by subsection (d) to the department
for review and approval in accordance with section 13(b) of this rule.
(f) The procedures that the owner
or operator of a secondary lead smelter specifies in the standard operating
procedures manual for inspections and routine maintenance must, at a minimum,
include the following requirements:
(1) Daily
monitoring of pressure drop across each baghouse cell.
(2) Weekly confirmation that dust is being
removed from hoppers through visual inspection, or equivalent means of ensuring
the proper functioning of removal mechanisms.
(3) Daily check of compressed air supply for
pulse-jet baghouses.
(4) An
appropriate methodology for monitoring cleaning cycles to ensure proper
operation.
(5) Monthly check of
bag cleaning mechanisms for proper functioning through visual inspection or
equivalent means.
(6) Monthly
check of bag tension on reverse air and shaker-type baghouses. The checks are
not required for shaker-type baghouses using self-tensioning or spring loaded
devices.
(7) Quarterly
confirmation of the physical integrity of the baghouse through visual
inspection of the baghouse interior for air leaks.
(8) Quarterly inspection of fans for wear,
material buildup, and corrosion through visual inspection, vibration detectors,
or equivalent means.
(9) Except as
provided in subsection (a), continuous operation of a bag leak detection
system, unless a system meeting the requirements of section 10(g) of this rule
for a CEMS is installed for monitoring the concentration of lead.
(g) The procedures specified in
the standard operating procedures manual for baghouse maintenance shall
include, at a minimum, a preventative maintenance schedule that is consistent
with the baghouse manufacturer's instructions for routine and long-term
maintenance.
(h) The owner or
operator of a secondary lead smelter shall operate a bag leak detection system
that meets the following requirements:
(1) The
bag leak detection system must be certified by the manufacturer to be capable
of detecting particulate matter emissions at concentrations of one (1)
milligram per actual cubic meter (forty-four hundred-thousandths (0.00044)
grains per actual cubic foot) or less.
(2) The bag leak detection system sensor must
provide output of relative particulate matter loadings, and the owner or
operator of a secondary lead smelter shall continuously record the output from
the bag leak detection system.
(3)
The bag leak detection system must be equipped with an alarm system that will
alert appropriate plant personnel when an increase in relative particulate
loadings is detected over a preset level. The alarm must be located where it
can be heard by the appropriate plant personnel.
(4) Each bag leak detection system must be
installed, calibrated, operated, and maintained consistent with the U.S. EPA
guidance document "Fabric Filter Bag Leak Detection Guidance"
(EPA-454/R-98-015, September 1997)* and with the manufacturer's written
specifications and recommendations.
(5) The initial adjustment of the system
must, at a minimum, consist of establishing the following:
(A) The baseline output by adjusting the
sensitivity (range).
(B) The
averaging period of the device.
(C) The alarm set points.
(D) The alarm delay time.
(6) Following initial adjustment
and except as detailed in the standard operating procedures and maintenance
plan required under subsection (f), the owner or operator of a secondary lead
smelter shall not adjust the system's:
(A)
sensitivity or range;
(B)
averaging period;
(C) alarm set
points; or
(D) alarm delay time.
The owner or operator of a secondary lead smelter shall not
increase the sensitivity of the system by more than one hundred percent (100%)
or decrease the sensitivity by more than fifty percent (50%) over a three
hundred sixty-five (365) day period unless the adjustment follows a complete
baghouse inspection that demonstrates that the baghouse is in good operating
condition.
(7)
For negative pressure, induced air baghouses, and positive pressure baghouses
that are discharged to the atmosphere through a stack, the owner or operator of
a secondary lead smelter shall install the bag leak detector downstream of the
baghouse and upstream of any wet acid gas scrubber.
(8) Where multiple detectors are required,
the system's instrumentation and alarm may be shared among detectors.
(i) In addition to the
record keeping and reporting requirements under section 14 of this rule, the
owner or operator of a secondary lead smelter shall comply with the following:
(1) Submit a report within thirty (30) days
after the end of each preceding six (6) month period ending June 30 and
December 31 of each year that includes the following:
(A) A description of the actions taken
following each bag leak detection system alarm pursuant to subsection (a).
(B) Calculations of the percentage
of total operating time, or the total operating time in hours and minutes the
alarm on the bag leak detection system was activated during the reporting
period.
(2) Records for
bag leak detection systems shall be maintained on site for a period of three
(3) years and be available for an additional two (2) years and shall include
the following information:
(A) Records of bag
leak detection system output.
(B)
Identification of the date and time of all bag leak detection system alarms.
