# §98.497. 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)](#a) and [(b)](#b) of this section.

- (a) The records of all parameters monitored under [§ 98.494](/cfr/40/98.494.md).
- (b) **The applicable verification software records as identified in this paragraph (b).** 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 (b)(1) through (5)](#b-1..b-5) of this section. Retention of this file satisfies the recordkeeping requirement for the data in [paragraphs (b)(1) through (5)](#b-1..b-5) of this section.
  - (1) Monthly mass of green coke fed to the coke calcining unit from facility records (metric tons/year) (equation 1 to [§ 98.493(b)(2)](/cfr/40/98.493.md?p=b-2)).
  - (2) Monthly mass of marketable petroleum coke produced by the coke calcining unit from facility records (metric tons/year) (equation 1 to [§ 98.493(b)(2)](/cfr/40/98.493.md?p=b-2)).
  - (3) Monthly mass of petroleum coke dust removed from the process through the dust collection system of the coke calcining unit from facility records (metric tons/year) (equation 1 to [§ 98.493(b)(2)](/cfr/40/98.493.md?p=b-2)).
  - (4) Average monthly mass fraction carbon content of green coke fed to the coke calcining unit from facility measurement data (metric tons C per metric ton green coke) (equation 1 to [§ 98.493(b)(2)](/cfr/40/98.493.md?p=b-2)).
  - (5) Average monthly mass fraction carbon content of marketable petroleum coke produced by the coke calcining unit from facility measurement data (metric tons C per metric ton petroleum coke) (equation 1 to [§ 98.493(b)(2)](/cfr/40/98.493.md?p=b-2)).
