Sec. 60.424  Test methods and procedures.

    (a) In conducting the performance tests required in Sec. 60.8, the 
owner or operator shall use as reference methods and procedures the test 
methods in appendix A of this part or other methods and procedures as 
specified in this section, except as provided in Sec. 60.8(b).
    (b) The owner or operator shall determine compliance with the 
particulate matter standards in Sec. 60.422 as follows:
    (1) The emission rate (E) of particulate matter shall be computed 
for each run using the following equation:

E=(cs Qsd)/(PK)

where:

E=emission rate of particulate matter, kg/Mg (lb/ton) of ammonium 
sulfate produced.
cs=concentration of particulate matter, g/dscm (g/dscf).
Qsd=volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
P=production rate of ammonium sulfate, Mg/hr (ton/hr).
K=conversion factor, 1000 g/kg (453.6 g/lb).

    (2) Method 5 shall be used to determine the particulate matter 
concentration (cs) and volumetric flow rate (Qsd) 
of the effluent gas. The sampling time and sample volume for each run 
shall be at least 60 minutes and 1.50 dscm (53 dscf).
    (3) Direct measurement using product weigh scales, or the result of 
computations using a material balance, shall be used to determine the 
rate (P) of the ammonium sulfate production. If production rate is 
determined by material balance, the following equations shall be used:
    (i) For synthetic and coke oven by-product ammonium sulfate plants:

P=ABCK\1/4\

where:

A=sulfuric aid flow rate to the reactor/crystallizer averaged over the 
time-period taken to conduct the run, liter/min.
B=acid density (a function of acid strength and temperature), g/cc.
C=acid strength, decimal fraction.
K\1/4\=conversion factor, 0.0808 (Mg-min-cc)/(g-hr-liter) [0.0891 (ton-
min-cc)/(g-hr-liter)].

    (ii) For caprolactam by-product ammonium sulfate plants:

P=DEFK''

where:

D=total combined feed stream flow rate to the ammonium crystallizer 
before the point where any recycle streams enter the stream averaged 
over the time-period taken to conduct the test run, liter/min.

[[Page 471]]

E=density of the process stream solution, g/liter.
F=percent mass of ammonium sulfate in the process solution, decimal 
fraction.
K''=conversion factor, 6.0x10-5 (Mg-min)/(g-hr) 
[6.614x10-5 (ton-min)/(g-hr)].

    (4) Method 9 and the procedures in Sec. 60.11 shall be used to 
determine the opacity.
