W = total weight of filtration waste for the time period
indicated.
Subscripts 1, 2, and 3 identify the time period of the
test.
(N) Method
for the determination of the length of time to operate the recovery cycle of a
solvent recovery dryer at a petroleum dry cleaning facility.
(1) This method is applicable to determining
the length of time for operating the solvent recovery cycle of a solvent
recovery dryer at a petroleum dry cleaning facility in order to assure that the
flow rate of recovered petroleum solvent at the termination of solvent recovery
cycle is no greater than fifty milliliters per minute.
(2) The dryer shall be tested under normal
operating conditions for a duration of no less than two weeks during which no
less than one-half of the dryer loads shall be monitored for their final
recovered solvent flow rate.
(3)
The suggested point for measuring the flow rate of recovered solvent is from
the outlet of the solvent-water separator. Near the end of the recovery cycle,
the entire flow of recovered solvent is diverted to a graduated cylinder. As
the recovered solvent collects in the graduated cylinder, the elapsed time is
monitored and recorded in periods greater than or equal to one minute. At the
same time, the volume of solvent in the graduated cylinder is monitored and
recorded to determine the volume of recovered solvent that is collected during
each time period. The recovered solvent flow rate is calculated by dividing the
volume of solvent collected per period by the length of time elapsed during the
period and converting the result with appropriate factors into units of
milliliters per minute. The recovery cycle and the monitoring procedure is
continued until the flow rate of solvent is less than or equal to fifty
milliliters per minute. The date, the type of articles cleaned, and the total
length of the recovery cycle shall be recorded for each dryer load being
monitored.
(O) Method
for the determination of equipment in VOC service and in light liquid service.
(1) This method is applicable to equipment at
a petroleum refinery or a process unit subject to paragraph (T) or (DD) of rule
3745-21-09 of the Administrative
Code.
(2) Any piece of equipment is
presumed to be in VOC service, unless the owner or operator demonstrates that
the piece of equipment is not in VOC service according to the following
provisions:
(a) The piece of equipment is
considered not in VOC service if it can be determined that the VOC content of
the process fluid, which is contained in or contacts the piece of equipment,
can be reasonably expected never to exceed ten per cent by weight.
(b) For purposes of determining the VOC
content of a process fluid, procedures that conform to the general methods
described in ASTM E168, ASTM E169,
and ASTM E260 shall be used.
(c) The owner or operator may use engineering
judgment rather than the procedures contained in paragraph (O)(2)(b) of this
rule to demonstrate that the VOC content of a process fluid does not exceed ten
per cent by weight, provided the VOC content clearly does not exceed ten per
cent by weight. In the event the Ohio EPA or the USEPA has a disagreement with
an engineering judgment, paragraph (O)(2)(b) of this rule shall be used to
resolve the disagreement.
(3) A piece of equipment is in light liquid
service if it contains or is in contact with a process fluid that meets all of
the following conditions:
(a) The process
fluid is a liquid at operating conditions.
(b) The vapor pressure of one or more of the
pure components within the process fluid is greater than 0.04 pound per square
inch at sixty-eight degrees Fahrenheit. Vapor pressures may be obtained from
standard reference texts or may be determined by the method in ASTM
D2879.
(c)
The total concentration of the pure components having a vapor pressure greater
than 0.04 pound per square inch at sixty-eight degrees Fahrenheit is equal to
or greater than twenty per cent by weight.
(P) Method for the determination of the net
heating value of a gas, the actual exit velocity for a flare, and the maximum
permitted velocity for an air-assisted flare.
(1) This method is applicable to the
following:
(a) Any flare subject to paragraph
(DD) of rule
3745-21-09 of the Administrative
Code.
(b) Any process vent stream
subject to paragraph (EE) of rule
3745-21-09 of the Administrative
Code.
(2) The net
heating value of gas being combusted in a flare or being vented from a process
vent stream shall be calculated using the following equation:
where:

HT = net heating value of the sample, in
mega joules per standard cubic meter (MJ/scm), where the net enthalpy per mole
of offgas is based on combustion at twenty-five degrees Celsius and seven
hundred sixty millimeters of mercury, but the standard temperature for
determining the volume corresponding to one mole is twenty degrees
Celsius.
k = constant, 1.740 × 10-7
(megajoule-gram mole per parts per million-standard cubic meter-kilocalorie),
where the standard temperature for gram-mole per standard cubic meter (g
mole/scm) is twenty degrees Celsius.
Ci = concentration of sample component i
in ppmv, as measured by the procedures in USEPA method 18, and ASTM
D1946 reported on a wet basis.
Hi = net heat of combustion of sample
component i, in kilocalories per grammole. The heat of combustion may be
determined using the procedures in ASTM D2382 if
published values are not available or cannot be calculated.
i = subscript denoting a specific component in the
sample.
n = total number of components within the
sample.
(3) The actual exit
velocity of a flare shall be calculated by dividing the volumetric flow rate
(in units of standard temperature and pressure) of the flare header or headers
that feed the flare, as determined by USEPA methods 2, 2A, 2C, or 2D as
appropriate, by the unobstructed (free) cross-sectional area of the flare tip,
as determined by design and engineering principles.
(4) The maximum permitted velocity of an
air-assisted flare shall be determined by the following equation:
Vmax = 8.706 + 0.7084(HT)
where:
Vmax = maximum permitted velocity of an
air-assisted flare, in meters per second (m/sec).
HT = the net heating value as determined
in paragraph (P)(2) of this rule.
(5) To express the net heating value of a gas
in Btu per standard cubic foot, multiply HTby 26.84.
(6) To express a velocity in feet per second,
multiply the velocity in meters per second by 3.281.
(Q) Method for the detection of leaks of
gasoline vapors from a vapor control system installed at a gasoline dispensing
facility (static leak test).
(1) This method
is applicable to quantifying the vapor tightness of a vapor balance system or a
vacuum assist control system installed at a gasoline facility.
(2) This method describes the procedures to
be followed for detecting leaks of gasoline vapors by pressurizing the entire
vapor recovery control system to two inches of water column and then allowing
the system pressure to decay for five minutes. The acceptability of the final
pressure is based upon the vapor system volume or ullage space. The allowable
five minute final pressure is based upon the gasoline tank ullage, pressure
decay equations, and the number of affected nozzles.
(3) The equipment, procedures, and pressure
decay leak criteria are specified in appendix A to this rule.
(R) Method for the determination
of the dynamic pressure performance for a vapor control system installed at a
gasoline dispensing facility (dynamic pressure performance test).
(1) This method is applicable to determining
the dynamic pressure at known dispensing flow rates for a vapor control system
installed at a gasoline dispensing facility. This method is used to quantify
the back pressure and detect liquid obstructions in the vapor path leading from
the dispensing nozzle to the gasoline storage tank.
(2) This method describes the procedures to
be followed in simulating the dynamic back pressures associated with known
gasoline dispensing rates and liquid blockages by passing nitrogen through the
vapor control system at three flow rates after liquid gasoline has been
introduced into the vapor return piping.
(3) The equipment, procedures, and dynamic
pressure performance criteria are identified in appendix B to this rule. The
post test inspection form, as required by paragraph (DDD)(2)(c) of rule
3745-21-09 of the Administrative
Code, is contained in appendix C to this rule.

sampling and analysis of the catalyst activity (i.e., conversion efficiency)
following the manufacturer's or catalyst supplier's recommended
procedures.
(2) Monthly inspection
of the oxidizer system including the burner assembly and fuel supply lines for
problems.
(3) Annual internal and
monthly external visual inspection of the catalyst bed to check for channeling,
