most recent notice of Type 1–A or Type 1–B rate adjustment.

(d) Unused rate adjustment authority generated under paragraph (a) of this section shall be subject to the limitation under § 3010.29, regardless of whether it is used alone or in combination with other existing unused rate adjustment authority.

■ 21. Add new § 3010.30 to read as follows:

**§ 3010.30 De minimis rate increases.**

(a) The Postal Service may elect to file a Type 1–A notice of rate adjustment as a de minimis rate increase if:

(1) For each affected class, the rate increases contained within the notice of a Type 1–A rate adjustment do not result in the percentage change in rates for the class equaling or exceeding 0.001 percent; and

(2) For each affected class, the sum of all rate increases included in de minimis rate increases since the most recent Type 1–A or Type 1–B rate adjustment that was not a de minimis rate increase does not result in the percentage change in rates for the class equaling or exceeding 0.001 percent.

(b) No unused rate adjustment authority will be added to the schedule of unused rate adjustment authority maintained under § 3010.26(f) as a result of a de minimis rate increase.

(c) No rate decreases may be taken into account when determining whether rate increases comply with paragraphs (a)(1) and (a)(2) of this section.

(d) In the next notice of a Type 1–A or Type 1–B rate adjustment for a class that is not a de minimis rate increase:

(1) The annual limitation shall be calculated as if the de minimis rate increase had not been filed; and

(2) For purposes of calculating the percentage change in rates, the current rate shall be the current rate from the de minimis rate increase.

(e) The Postal Service shall file supporting workpapers with each notice of de minimis rate increase that demonstrate that the sum of all rate increases included in de minimis rate increases since the most recent Type 1– A or Type 1–B notice of rate adjustment that was not de minimis does not result in a percentage change in rates for the class equaling or exceeding 0.001 percent.
