§ 63.626 Performance tests and compliance provisions.
(a)
(1) On or before the applicable compliance date in § 63.630 and once per annum thereafter, each owner or operator of a phosphate fertilizers production plant subject to the provisions of this subpart shall conduct a performance test to demonstrate compliance with the applicable emission standard for each existing diammonium and/or monoammonium phosphate process line, granular triple superphosphate process line, or granular triple superphosphate storage building. The owner or operator shall conduct the performance test according to the procedures in subpart A of this part and in this section.
(2) As required by § 63.7(a)(2) and once per annum thereafter, each owner or operator of a phosphate fertilizers production plant subject to the provisions of this subpart shall conduct a performance test to demonstrate compliance with the applicable emission standard for each new diammonium and/or monoammonium phosphate process line, granular triple superphosphate process line, or granular triple superphosphate storage building. The owner or operator shall conduct the performance test according to the procedures in subpart A of this part and in this section.
(b) In conducting performance tests, each owner or operator of an affected source shall use as reference methods and procedures the test methods in 40 CFR part 60, appendix A, or other methods and procedures as specified in this section, except as provided in § 63.7(f).
(c) Each owner or operator of a new or existing diammonium and/or monoammonium phosphate process line or granular triple superphosphate process line shall determine compliance with the applicable total fluorides standards in § 63.622 or § 63.623 as follows:
(1) The emission rate (E) of total fluorides shall be computed for each run using the following equation:
Where:
E = emission rate of total fluorides, g/metric ton (lb/ton) of equivalent P2O5 feed.
Csi = concentration of total fluorides from emission point “i,” mg/dscm (mg/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, 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. If Method 13 B is used, the fusion of the filtered material described in section 7.3.1.2 and the distillation of suitable aliquots of containers 1 and 2, described in sections 7.3.3 and 7.3.4 in Method 13 A, may be omitted. The sampling time and sample volume for each run shall be at least one hour 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 § 63.625(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:
(A) Section IX, Methods of Analysis for Phosphate Rock, No. 1 Preparation of Sample.
(B) Section IX, Methods of Analysis for Phosphate Rock, No. 3 Phosphorus—P2O5 or Ca3(PO4)2, Method A—Volumetric Method.

(G) Section XI, Methods of Analysis for Phosphoric Acid, Superphosphate, Triple Superphosphate, and Ammonium Phosphates, No. 3 Total Phosphorus-P2O5, Method C—Spectrophotometric Method.
(4) To comply with § 63.625(f)(1) or (2), the owner or operator shall use the monitoring systems in § 63.625(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 § 63.625(f)(1) or (2).
(d) Each owner or operator of a new or existing granular triple superphosphate storage building shall determine compliance with the applicable total fluorides standards in § 63.622 or § 63.623 as follows:
(1) The owner or operator shall conduct performance tests only when the following quantities of product are being cured or stored in the facility.
(i) Total granular triple superphosphate is at least 10 percent of the building capacity, and
(ii) Fresh granular triple superphosphate is at least six percent of the total amount of granular triple superphosphate, or
(iii) If the provision in paragraph (d)(1)(ii) of this section exceeds production capabilities for fresh granular triple superphosphate, fresh granular triple superphosphate is equal to at least 5 days maximum production.
(2) In conducting the performance test, the owner or operator shall use as reference methods and procedures the test methods in 40 CFR part 60, appendix A, or other methods and procedures as specified in this section, except as provided in § 63.7(f).
