point ``i,'' dscm/hr (dscf/hr).N = number of emission points associated with the affected facility.P = equivalent P2O5 feed rate, metric ton/hr (ton/
hr).K = conversion factor, 1000 mg/g (453,600 mg/lb).
(2) Method 13A or 13B (40 CFR part 60, appendix A) 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 using the following equation: P = Mp Rp Where: Mp = total mass flow rate of phosphorus-bearing feed, metric
ton/hr (ton/hr).Rp = P2O5 content, decimal fraction.
(i) The accountability system described in Sec. 63.605(a) and (b) shall be used to determine the mass flow rate (Mp) of the phosphorus-bearing feed.
(ii) The P2O5 content (Rp) of the feed shall be determined using as appropriate the following methods (incorporated by reference--see 40 CFR 63.14) specified in the Book of Methods Used and Adopted By The Association Of Florida Phosphate Chemists, Seventh Edition 1991, where applicable:

(4) To comply with Sec. 63.605(d) (1) or (2), the owner or operator shall use the monitoring systems in Sec. 63.605(c) to determine the average pressure loss of the gas stream across each scrubber in the process scrubbing system and to determine the average flow rate of the scrubber liquid to each scrubber in the process scrubbing system during each of the total fluoride runs. The arithmetic averages of the three runs shall be used as the baseline average values for the purposes of Sec. 63.605(d) (1) or (2).
(d) Each owner or operator of a new or existing phosphate rock dryer shall demonstrate compliance with the particulate matter standards in Sec. 63.602 or Sec. 63.603 as follows:
(1) The emission rate (E) of particulate matter shall be computed for each run using the following equation: E = (Cs Qsd)/(P K) Where: E = emission rate of particulate matter, kg/Mg (lb/ton) of phosphate
rock feed.Cs = concentration of particulate matter, g/dscm (g/dscf).Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/

The arithmetic average of the one-hour averages determined during the three test runs shall be used as the baseline average values for the purposes of Sec. 63.605(d) (1) or (2).
