(a) Sampling methodology used must conform to ARB testing procedures. Alternate or modified test methods may be used if approved in writing by the Executive Officer prior to use for certification.
Testing shall be conducted in accordance with the following methods, which are incorporated by reference herein:
| NOx, CO, and Oxygen: | ARB Test Method 100 (as adopted on July 28, 1997) |
| | |
| VOC: | South Coast AQMD Method 25.3 (as published in March 2000) |
| | |
| Gas Velocity and Flow Rate: | ARB Test Methods 1, 2, 3, and 4 (as adopted on July 1, 1999) |
(b) Only natural gas, LPG, digester gas, landfill gas, or oil-field waste gas, as defined in section 94202, meeting the requirements of section 94207(d)(7) shall be used for certification testing. Other fuels may be used upon the written approval of the Executive Officer.(c) The DG Unit shall be configured as it will be marketed, including any additional control equipment or other devices that affect emissions.(d) Testing parameters. (1) A minimum of three valid test runs must be conducted. Tests are to be run consecutively. Justification for invalid test runs or time gaps between runs must be included in the test report.(2) Testing commences after the DG Unit has reached stable operation.(3) Each run must be conducted at 100 percent of generator net output. (A) A load bank may be used to establish the load.(B) The DG Unit must be operated for a sufficient period of time to demonstrate stability in the emission readings at constant load and to ensure the collection of representative and quantifiable samples.(4) Generator output (MW-hr), based on net output, shall be measured during each valid test run. A calibrated electric meter shall be used for the measurements. The meter shall meet the American National Standards Institute's Code for Electricity Metering (ANSI C12.1-as of July 9, 2001).(5) Recovered heat shall be measured using a water loop device, measuring the water flow rate, inlet temperature, and outlet temperature.(6) The emission rate shall be expressed in lb/MW-hr.(7) Certification Fuels (B) LPG that meets the standards of HD-5 propane.(C) Surrogate digester gas that is composed of 60 to 65 percent methane and 35 to 40 percent CO2, by volume.(D) Surrogate landfill gas that is composed of 42 to 46 percent methane, 34 to 38 percent CO2, and 18 to 22 percent N2, by volume.(E) Surrogate oil-field waste gas that is composed of 63 to 71 percent methane, 6 to 8 percent ethane, 9 to 11 percent propane, 7 to 9 percent CO2, and 7 to 8 percent carbon compounds with four or more carbon atoms per molecule, by volume.(e) Alternative testing procedures may be used upon written approval of the Executive Officer, if alternative procedures are deemed to be equivalent or more accurate than the prescribed procedures.Cal.
