(1) General limitations:
(a) Except as otherwise specified in
paragraphs (A)(1)(b), (A)(2) and (A)(3) of this rule, visible particulate
emissions from any stack shall not exceed twenty per cent opacity, as a
six-minute average.
(b) Except as
otherwise specified in paragraphs (A)(2) and (A)(3) of this rule, visible
particulate emissions from any stack may exceed twenty per cent opacity, as a
six-minute average, for not more than six consecutive minutes in any sixty
minutes, but shall not exceed sixty per cent opacity, as a six-minute average,
at any time.
(3) The visible particulate emission
limitations established in paragraph (A)(1) of this rule shall not apply to the
following:
(a) The start-up of the following
fuel burning equipment:
(i) For any fuel
burning equipment which are equipped with baghouses or electrostatic
precipitators, until the exhaust gases have achieved a temperature of two
hundred fifty degrees Fahrenheit at the inlet of the baghouses or electrostatic
precipitators, provided that the director may incorporate a higher start-up
temperature in the permit or variance for such source for which an applicant
demonstrates to the satisfaction of the director that the higher temperature is
needed for safety considerations or to prevent damage to the control
equipment.
(ii) For any fuel
burning equipment which are uncontrolled or which are equipped solely with
mechanical collectors (including mechanical collectors which are equipped with
sidestream separators or similar devices) for the control of particulate
emissions, for a period of not more than three hours from the moment of
start-up, provided that the director may incorporate a longer start-up time
period in the permit or variance for such source for which an applicant
demonstrates to the satisfaction of the director that the longer time period is
required.
(b) The
shutdown of the following fuel burning equipment:
(i) For any fuel burning equipment which are
equipped with baghouses or electrostatic precipitators, after the temperature
of the exhaust gases has dropped below two hundred fifty degrees Fahrenheit at
the inlet of the baghouses or electrostatic precipitators, provided that the
director may incorporate a higher shutdown temperature in the permit or
variance for such source for which an applicant demonstrates to the
satisfaction of the director that the higher temperature is needed for safety
considerations or to prevent damage to the control equipment.
(ii) For any fuel burning equipment which are
uncontrolled or which are equipped solely with mechanical collectors (including
mechanical collectors which are equipped with sidestream separators or similar
devices) for the control of particulate emissions, for a period of not more
than three hours, provided that the director may incorporate a longer shutdown
time period in the permit or variance for such source for which an applicant
demonstrates to the satisfaction of the director that the longer time period is
required.
(c) The
malfunction of any air contaminant source or the malfunction/shutdown of air
pollution control equipment associated with any air contaminant source, if the
owner or operator of said air contaminant source or air pollution control
equipment complies with
the requirements of
rule
3745-15-06
of the Administrative Code and none of the conditions listed in paragraph (C)
of rule
3745-15-06
of the Administrative Code exists.
(d) Intermittent soot-blowing operations (the
cleaning of heat transfer surfaces with pressurized air or steam) for fuel
burning equipment which are uncontrolled or which are equipped solely with
mechanical collectors (including mechanical collectors which are equipped with
sidestream separators or similar devices) for the control of particulate
emissions, provided that the owner or operator of such fuel burning equipment
maintains a daily record which clearly documents the date, beginning time and
ending time for all intermittent soot-blowing operations.
(e) Salt glazing operations conducted in a
gas-fired periodic brick or tile kiln, for a period of not more than two hours
during any twenty-one consecutive days of operation of said kiln.
(f) Intermittent ash removal operations (the
dumping or pulling of ash) for fuel burning equipment which are uncontrolled or
which are equipped solely with mechanical collectors (including mechanical
collectors which are equipped with sidestream separators or similar devices)
for the control of particulate emissions, provided that the owner or operator
of such fuel burning equipment maintains a daily record which clearly documents
the date, beginning time and ending time for all intermittent ash removal
operations.
(g) The commencement of
increased coal firing from a banked condition for fuel burning equipment, for a
period not to exceed thirty minutes.
(h) Any air contaminant source which is not
subject to any mass emission limitation in paragraphs (B)(3) and (B)(4) of rule
3745-17-08
of the Administrative Code, or rule
3745-17-09,
3745-17-10
or
3745-17-11
of the Administrative Code.
(i) Any
air contaminant source for which an equivalent visible particulate emission
limitation has been established by the director pursuant to paragraph (C) of
this rule.
(j) The following kiln
operations at the facility (OEPA premise number 0372000127) located at 755 Lime
Road, Woodville, Ohio, provided that "Martin Marietta Magnesia Specialties,
Inc.," or any subsequent owner or operator of such facility, maintains daily
records that clearly document the dates, beginning times, and ending times for
the operations:
(i) The start-up of any kiln
equipped with a baghouse, until the time stone feed to the kiln
begins.
(ii) The start-up of any
kiln equipped with an electrostatic precipitator, from the time the stone feed
to the kiln begins until the time a stable firing condition for the solid fuel
is achieved, but not longer than six hours from the time firing with the solid
fuel begins.
(iii) The shutdown of
any kiln equipped with a baghouse, after the time the temperature of the
exhaust gases from the kiln has dropped below two hundred fifty degrees
Fahrenheit at the inlet of the baghouse.
For the purposes of this paragraph, "start-up" shall be defined
as the point of commencement of firing the kiln until such time as the process
is operating in a steady-state condition using its primary fuel. A steady-state
condition is present when the throughputs of process material, fuel and
combustion air have been stabilized in a manner that demonstrates the
combustion process will be consistently complete and safe, with an exhausted
combustibles concentration within established safety limits.
