Sec. 63.6620  What performance tests and other procedures must I use?



    (a) You must conduct each performance test in Tables 3 and 4 of this 

subpart that applies to you.

    (b) Each performance test must be conducted according to the 

requirements in Sec. 63.7(e)(1) and under the specific conditions that 

this subpart specifies in Table 4. The test must be conducted at any 

load condition within plus or minus 10 percent of 100 percent load.

    (c) You may not conduct performance tests during periods of startup, 

shutdown, or malfunction, as specified in Sec. 63.7(e)(1).

    (d) You must conduct three separate test runs for each performance 

test required in this section, as specified in Sec. 63.7(e)(3). Each 

test run must last at least 1 hour.

    (e)(1) You must use Equation 1 of this section to determine 

compliance with the percent reduction requirement:

Where:



Ci = concentration of CO or formaldehyde at the control 

device inlet,

Co = concentration of CO or formaldehyde at the control 

device outlet, and

R = percent reduction of CO or formaldehyde emissions.



    (2) You must normalize the carbon monoxide (CO) or formaldehyde 

concentrations at the inlet and outlet of the control device to a dry 

basis and to 15 percent oxygen, or an equivalent percent carbon dioxide 

(CO2). If pollutant concentrations are to be corrected to 15 

percent oxygen and CO2 concentration is measured in lieu of 

oxygen concentration measurement, a CO2 correction factor is 

needed. Calculate the CO2 correction factor as described in 

paragraphs (e)(2)(i) through (iii) of this section.

    (i) Calculate the fuel-specific Fo value for the fuel 

burned during the test using values obtained from Method 19, section 

5.2, and the following equation:

Where:





[[Page 19]]





Fo = Fuel factor based on the ratio of oxygen volume to the 

ultimate CO2 volume produced by the fuel at zero percent 

excess air.

0.209 = Fraction of air that is oxygen, percent/100.

Fd = Ratio of the volume of dry effluent gas to the gross 

calorific value of the fuel from Method 19, dsm 3/J (dscf/10 

6 Btu).

Fc = Ratio of the volume of CO2 produced to the 

gross calorific value of the fuel from Method 19, dsm 3/J 

(dscf/10 6 Btu).



    (ii) Calculate the CO2 correction factor for correcting 

measurement data to 15 percent oxygen, as follows:

[GRAPHIC] [TIFF OMITTED] TR15JN04.014



Where:



Xco2 = CO2 correction factor, percent.

5.9 = 20.9 percent O2-15 percent O2, the defined 

O2 correction value, percent.



    (iii) Calculate the NOX and SO2 gas 

concentrations adjusted to 15 percent O2 using CO2 

as follows:

Where:



%CO2 = Measured CO2 concentration measured, dry 

basis, percent.



    (f) If you comply with the emission limitation to reduce CO and you 

are not using an oxidation catalyst, if you comply with the emission 

limitation to reduce formaldehyde and you are not using NSCR, or if you 

comply with the emission limitation to limit the concentration of 

formaldehyde in the stationary RICE exhaust and you are not using an 

oxidation catalyst or NSCR, you must petition the Administrator for 

operating limitations to be established during the initial performance 

test and continuously monitored thereafter; or for approval of no 

operating limitations. You must not conduct the initial performance test 

until after the petition has been approved by the Administrator.

    (g) If you petition the Administrator for approval of operating 

limitations, your petition must include the information described in 

paragraphs (g)(1) through (5) of this section.

    (1) Identification of the specific parameters you propose to use as 

operating limitations;

    (2) A discussion of the relationship between these parameters and 

HAP emissions, identifying how HAP emissions change with changes in 

these parameters, and how limitations on these parameters will serve to 

limit HAP emissions;

    (3) A discussion of how you will establish the upper and/or lower 

values for these parameters which will establish the limits on these 

parameters in the operating limitations;

    (4) A discussion identifying the methods you will use to measure and 

the instruments you will use to monitor these parameters, as well as the 

relative accuracy and precision of these methods and instruments; and

    (5) A discussion identifying the frequency and methods for 

recalibrating the instruments you will use for monitoring these 

parameters.

    (h) If you petition the Administrator for approval of no operating 

limitations, your petition must include the information described in 

paragraphs (h)(1) through (7) of this section.

    (1) Identification of the parameters associated with operation of 

the stationary RICE and any emission control device which could change 

intentionally (e.g., operator adjustment, automatic controller 

adjustment, etc.) or unintentionally (e.g., wear and tear, error, etc.) 

on a routine basis or over time;

    (2) A discussion of the relationship, if any, between changes in the 

parameters and changes in HAP emissions;

    (3) For the parameters which could change in such a way as to 

increase HAP emissions, a discussion of whether establishing limitations 

on the parameters would serve to limit HAP emissions;

    (4) For the parameters which could change in such a way as to 

increase HAP emissions, a discussion of how you could establish upper 

and/or lower values for the parameters which would establish limits on 

the parameters in operating limitations;

    (5) For the parameters, a discussion identifying the methods you 

could use to measure them and the instruments you could use to monitor 

them, as well as the relative accuracy and precision of the methods and 

instruments;



[[Page 20]]



    (6) For the parameters, a discussion identifying the frequency and 

methods for recalibrating the instruments you could use to monitor them; 

and

    (7) A discussion of why, from your point of view, it is infeasible 

or unreasonable to adopt the parameters as operating limitations.

    (i) The engine percent load during a performance test must be 

determined by documenting the calculations, assumptions, and measurement 

devices used to measure or estimate the percent load in a specific 

application. A written report of the average percent load determination 

must be included in the notification of compliance status. The following 

information must be included in the written report: the engine model 

number, the engine manufacturer, the year of purchase, the 

manufacturer's site-rated brake horsepower, the ambient temperature, 

pressure, and humidity during the performance test, and all assumptions 

that were made to estimate or calculate percent load during the 

performance test must be clearly explained. If measurement devices such 

as flow meters, kilowatt meters, beta analyzers, stain gauges, etc. are 

used, the model number of the measurement device, and an estimate of its 

accurate in percentage of true value must be provided.
