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.

SUPPLEMENTARY INFORMATION: In the 

Final Rules section of this Federal 

Register, EPA is approving the State’s 

SIP submittal as a direct final rule 

without prior proposal because the 

Agency views this as a noncontroversial 

submittal and anticipates no adverse 

comments. A detailed rationale for the 

approval is set forth in the direct final 

rule. If no adverse comments are 

received in response to this rule, no 

further activity is contemplated. If EPA 

receives adverse comments, the direct 

final rule will be withdrawn and all 

public comments received will be 

addressed in a subsequent final rule 

based on this proposed rule. EPA will 

not institute a second comment period. 

Any parties interested in commenting 

on this action should do so at this time. 

Please note that if EPA receives adverse 

comment on an amendment, paragraph, 

or section of this rule and if that 

provision may be severed from the 

remainder of the rule, EPA may adopt 

as final those provisions of the rule that 

are not the subject of an adverse 

comment. For additional information, 

see the direct final rule which is located 

in the Rules section of this Federal 

Register.
