40 CFR §63.1385

1. (a)The owner or operator shall use the following methods to determine compliance with the applicable emission limits:
   1. (1)Method 1 (40 CFR part 60, appendix A) for the selection of the sampling port location and number of sampling ports;
   2. (2)Method 2 (40 CFR part 60, appendix A) for volumetric flow rate;
   3. (3)Method 3 or 3A (40 CFR part 60, appendix A) for O2 and CO2 for diluent measurements needed to correct the concentration measurements to a standard basis;
   4. (4)Method 4 (40 CFR part 60, appendix A) for moisture content of the stack gas;
   5. (5)Method 5 or Method 29 (40 CFR part 60, appendix A-3) for the concentration of total PM. When using Method 5, each run must consist of a minimum sample volume of 2 dry standard cubic meters (dscm). When using Method 29, each run must consist of a minimum sample volume of 3 dscm. When measuring PM concentration using either Method 5 or 29, the probe and filter holder heating system must be set to provide a gas temperature no greater than 120±14 °C (248±25 °F).
   6. (6)For measuring the concentration of formaldehyde, use one of the following test methods:
      1. (i)Method 318 (appendix A of this part). Each test run must consist of a minimum of 10 spectra.
      2. (ii)Method 316 (appendix A of this part). Each test run must consist of a minimum of 2 dry standard cubic meters (dscm) of sample volume.
   7. (7)Method contained in appendix A of this subpart for the determination of product LOI;
   8. (8)Method contained in appendix B of this subpart for the determination of the free-formaldehyde content of resin. The owner or operator shall use vendor specifications to determine the free-phenol content of resin.
   9. (9)Method contained in appendix C of this subpart for the determination of product density;
   10. (10)For measuring the concentration of phenol, use Method 318 (appendix A of this part). Each test run must consist of a minimum of 10 spectra.
   11. (11)For measuring the concentration of methanol, use one of the following test methods:
       1. (i)Method 318 (appendix A of this part). Each test run must consist of a minimum of 10 spectra.
       2. (ii)Method 308 (appendix A of this part). Each test run must consist of a minimum of 2 hours.
   12. (12)Method 29 (40 CFR part 60, appendix A-8) for the concentration of chromium compounds. Each test run must consist of a minimum sample volume of 3 dscm.
   13. (13)An alternative method, subject to approval by the Administrator.
2. (b)Each performance test shall consist of 3 runs. The owner or operator shall use the average of the three runs in the applicable equation for determining compliance.
