Sec. 60.204  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 total 
fluorides standard in Sec. 60.202 as follows:
    (1) The emission rate (E) of total fluorides shall be computed for 
each run using the following equation:
[GRAPHIC] [TIFF OMITTED] TC16NO91.007

where:

E=emission rate of total fluorides, g/Mg (lb/ton) of equivalent 
P2O5 feed.
Csi=concentration of total fluorides from emission point 
``i,'' mg/dscm (gr/dscf).
Qsdi=volumetric flow rate of effluent gas from emission point 
``i,'' dscm/hr (dscf/hr).
N=number of emission points associated with the affected facility.
P=equivalent P2O5 feed rate, Mg/hr (ton/hr).
K=conversion factor, 1000 mg/g (7,000 gr/lb).

    (2) Method 13A or 13B shall be used to determine the total fluorides 
concentration (Csi) and volumetric flow rate 
(Qsdi) of the effluent gas from each of the emission points. 
The sampling time and sample volume for each run shall be at least 60 
minutes and 0.85 dscm (30 dscf).
    (3) The equivalent P2O5 feed rate (P) shall be 
computed for each run using the following equation:

P=Mp Rp

where:

Mp=total mass flow rate of phosphorus-bearing feed, Mg/hr 
(ton/hr).
Rp=P2O5 content, decimal fraction.

    (i) The accountability system of Sec. 60.203(a) shall be used to 
determine the mass flow rate (Mp) of the phosphorus-bearing 
feed.
    (ii) The Association of Official Analytical Chemists (AOAC) Method 9 
(incorporated by reference--see Sec. 60.17) shall be used to determine 
the P2O5 content (Rp) of the feed.
