(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
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" means 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 steadystate 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.
(k) Residential wood burning appliances and
pellet stoves.
