# §98.197. 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 (c)](#a..c) of this section.

- (a) **Annual operating hours in calendar year.**
- (b) Records of all analyses (e.g. chemical composition of lime products, by type) and calculations conducted.
- (c) **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 (c)(1) through (9)](#c-1..c-9) of this section. Retention of this file satisfies the recordkeeping requirement for the data in [paragraphs (c)(1) through (9)](#c-1..c-9) of this section.
  - (1) Monthly calcium oxide content for each lime type, determined according to [§ 98.194(c)](/cfr/40/98.194.md?p=c) (metric tons CaO/metric ton lime) (Equation S-1 of [§ 98.193](/cfr/40/98.193.md)).
  - (2) Monthly magnesium oxide content for each lime type, determined according to [§ 98.194(c)](/cfr/40/98.194.md?p=c) (metric tons MgO/metric ton lime) (Equation S-1).
  - (3) Monthly calcium oxide content for each calcined lime byproduct or waste type sold (metric tons CaO/metric ton lime) (Equation S-2 of [§ 98.193](/cfr/40/98.193.md)).
  - (4) Monthly magnesium oxide content for each calcined lime byproduct or waste type sold (metric tons MgO/metric ton lime) (Equation S-2).
  - (5) Calcium oxide content for each calcined lime byproduct or waste type that is not sold (metric tons CaO/metric ton lime) (Equation S-3 of [§ 98.193](/cfr/40/98.193.md)).
  - (6) Magnesium oxide content for each calcined lime byproduct or waste type that is not sold (metric tons MgO/metric ton lime) (Equation S-3).
  - (7) Annual weight or mass of calcined byproducts or wastes for lime type that is not sold (tons) (Equation S-3).
  - (8) Monthly weight or mass of each lime type produced (tons) (Equation S-4 of [§ 98.193](/cfr/40/98.193.md)).
  - (9) **Monthly weight or mass of each calcined byproducts or wastes sold (tons) (Equation S-4).**
