# §98.267. Records that must be retained.


In addition to the records required by [§ 98.3(g)](/cfr/40/98.3.md?p=g), you must retain the records specified in [paragraphs (a) through (d)](#a..d) of this section for each wet-process phosphoric acid production facility.

- (a) **Monthly mass of phosphate rock consumed by origin (tons).**
- (b) **Records of all phosphate rock purchases and/or deliveries (if vertically integrated with a mine).**
- (c) Documentation of the procedures used to ensure the accuracy of monthly phosphate rock consumption by origin.
- (d) **Verification software records.** You must keep a record of the file generated by the verification software specified in [§ 98.5(b)](/cfr/40/98.5.md?p=b) for the applicable data specified in [paragraphs (d)(1) through (4)](#d-1..d-4) of this section. Retention of this file satisfies the recordkeeping requirement for the data in [paragraphs (d)(1) through (4)](#d-1..d-4) of this section.
  - (1) Inorganic carbon content of a grab sample batch of phosphate rock by origin obtained during month by wet-process phosphoric acid process line, from the carbon analysis results (percent by weight, expressed as a decimal fraction) (Equation Z-1a of [§ 98.263](/cfr/40/98.263.md)).
  - (2) Mass of phosphate rock by origin consumed in month by wet-process phosphoric acid process line (tons) (Equation Z-1a).
  - (3) Carbon dioxide content of a grab sample batch of phosphate rock by origin obtained during month by wet-process phosphoric acid process line (percent by weight, expressed as a decimal fraction) (Equation Z-1b of [§ 98.263](/cfr/40/98.263.md)).
  - (4) Mass of phosphate rock by origin consumed in month by wet-process phosphoric acid process line (tons) (Equation Z-1b).
