(1) The methods and procedures for
determining the efficiency of volatile organic compound (VOC) capture systems
shall be as specified in the EPA's Capture Efficiency Testing Guidance, dated
January 9, 1995, unless an alternate method or procedure has been approved by
the EPA and the Technical Secretary. This EPA guidance document can be obtained
from the Technology Transfer Network (TTN) bulletin board, located in the
Emission Measurement Technical Information (EMTIC) section, document number GD
- 035.
(2) The methods and
procedures for determining the destruction or removal efficiency and monitoring
parameters of incinerators and carbon adsorbers shall be according to the
following, unless an alternate method or procedure has been approved by the EPA
and the Technical Secretary:
(a) Testing
shall be as follows:
1. The control device
destruction or removal efficiency shall be determined from data obtained by
simultaneously measuring the inlet and outlet gas-phase VOC concentrations and
gas volumetric flow rates in accordance with the gas-phase test methods
specified in this chapter. The control device destruction or removal efficiency
shall be calculated using the following equation:

where:
E = VOC destruction efficiency of the control device;
Qi = Volumetric flow rate of the effluent gas flowing through
stack i entering the control device, dry standard cubic meters per hour
(dscmh);
Ci = Concentration of VOC (as carbon) in the effluent gas
flowing through stack i entering the control device, ppmv;
Qj = Volumetric flow rate of the effluent gas flowing through
stack j leaving the control device, dscmh;
Cj = Concentration of VOC (as carbon) in the effluent gas
flowing through stack j leaving the control device, ppmv;
n = The number of vents to the control device; and m = The
number of vents after the control device.
2. and 3. (Reserved)
(b) Monitoring shall be as follows:
1. Any owner or operator who uses an
incinerator or carbon adsorber for which stack emission testing is required to
demonstrate compliance with any standard of this chapter shall install,
calibrate, certify to the Technical Secretary, operate, and maintain continuous
monitoring equipment. The continuous monitoring equipment shall monitor the
following parameters:
(i) Combustion chamber
temperature of each thermal incinerator or afterburner;
(ii) Temperature immediately before the
catalytic incinerator and temperature rise across each catalytic incinerator
bed; and
(iii) The VOC
concentration of the outlet from each carbon adsorption bed.
2. The continuous temperature
monitoring equipment must be equipped with a continuous recorder and have an
accuracy of _+ 1 percent of the combustion temperature being measured expressed
in degrees Celsius ( °C) or _+0.5°C , whichever is greater.
(3) The overall
emission reduction efficiency of the emission control system shall be
determined as the product of the capture efficiency and the control device
destruction or removal efficiency; or for each emission control system in which
solvent is recovered, by a method approved by the EPA and Technical Secretary.
The results of a capture efficiency test and control device destruction or
removal efficiency test remain valid until a subsequent test is performed. The
results of any valid test may be used until superseded by the results of a
valid test subsequently performed.
