(b) Any faclllty under paragraph (s) of this section that commences con sLructlon or modlflcatlon after Octo- ber 22, 1979, Is subJect to the requlre- menls of this subpart. I42 F'It 37039, July Z5, 10771 ®60.Yd1 Definitiuna, As used In Chls subpart, all terms not defined herein shall have the meaning given them In the Act and In Subpart A of this part. (a) "G ranutar Crlple superphosphate storage faclllty" means any facility curing or storing granular triple super- phosphate, (b) "Total fluorides" means elemen- tal fluorine and ell fluoride com- pounds as measured 6y reference methods specified In 4 60.244, or equly slant or alternative methods. (c) "Equivalent P,O, stored" means the quantity oI phosphorus, expressed as phosphorus pentoxide, belne cured or stored In the affected faclllty. (d) "Fresh granular Crlple super phosphate" means granular triple su• perpllosphate produced no more than 10 days prior to the date of the per- formance test. 860.242 Standard for nuorides. (a) On and after the date on which the performance test required to be conducted by 4 60.8 Is completed, no owner or operator subJect to the Drovl- slons of this subpart shall cause to be discharged Into Lhe atmosphere from any affected faclllty any gases which contain total fluorides In excess of 0.25 g/!Ir/metric ton of equivalent P,O, stored (5.0 x 10-' Ib/hr/ton of equiva- lent P,O, alored). C 60.243 Afonltoring of operstlons. (a) The owner or operator of any granular triple superphosphate stor• age faclllty subJect to the provisions of this subpart shall maintain an accu• rate account of triple superphosphate In storage to permit the determinatlon of the amount of equivalent P,O, stored. 40 CFR Ch. 1 (7-I-89 Edltlon) (b) The owner or operator of any granular triple superphosphate stor- age faclllty shall matntaln a dally record of total equivalent P,O, stored by multiplying the percentage P,O, content, as determined by 4 60.244(c)(3), times the total mess of granular triple superphosphate stored. (c) The owner or operator of any granular Crlple superphosphate stor- age faclllty subJect to the provisions of this part shall Install, calibrate, maln- taln, and operate a monltorine device which continuously measures and per• manenLly records the total pressure drop across the process scrubbing system. The monitoring device shall have an accuracy of t5 percent over Its operating range.

(1) Total granular Crlple superphos- phate Is at least 10 percent of the building capacity and (2) Fresh granular Crlple superphos- phate 18 at least 20 percent o[ the total amount of Crlple superphosphate or, /3) If the prov)slon In paragraph (a)(2) of this section exceeds produc- tion caDabllltles for fresh granular triple superphosphate, fresh granular [rlpit superphosphate 13 equal to~ at least 5 days maximum production. (b3 In conducting the performance tests required In q 80.8, the oavner or operator shall use a$ reference meth- ods and procedures the teat methods In Appendix A of this Dart or other methods and procedures u specified In this section, except as provided In q 80.8(b). (c) The owner or operator shall de- termine compliance with the total fluorides standard In 4 80.292 as fol- lowa: (1) The emission rate (E) o- total fluorides shall be computed for each run using the following equation: N I.I Envlronm~nlol Proft.ctlon Ayancy where: E=emission rate of total nuorldes, ¢/hr/ metric ton (Ib/hr/ton) of equlvWent P,O, stored.
