Section 1200-03-18-.83 - TEST METHODS AND COMPLIANCE PROCEDURES: EMISSION CAPTURE AND DESTRUCTION OR REMOVAL EFFICIENCY AND MONITORING REQUIREMENTS

(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.
