(d) The Postal Service shall file a request to review its notice of rate adjustment with the Commission no later than 90 days prior to the planned implementation date of the rate adjustment.

(a) A rate adjustment filing under § 3030.121 shall include the items specified in paragraphs (b) through (j) of this section.

(b) A representation or evidence that public notice of the planned changes has been issued or will be issued at least 90 days before the effective date(s) for the planned rate adjustments.

(c) The intended effective date(s) of the planned rate adjustments.

(d) A schedule of the planned rate adjustments, including a schedule identifying every change to the Mail Classification Schedule that will be necessary to implement the planned rate adjustments.

(e) The identity of a responsible Postal Service official who will be available to provide prompt responses to requests for clarification from the Commission.

(f) The supporting technical documentation as described in § 3030.123.

(g) A demonstration that the planned rate adjustments are consistent with 39 U.S.C. 3626, 3627, and 3629.

(h) A certification that all cost, avoided cost, volume, and revenue figures submitted with the rate adjustment filing are developed from the most recent applicable Commission accepted analytical principles.

(i) For a rate adjustment that only includes a decrease in rates, a statement of whether the Postal Service elects to generate unused rate adjustment authority.

(j) Such other information as the Postal Service believes will assist the Commission in issuing a timely determination of whether the planned rate adjustments are consistent with applicable statutory policies.

(a) Supporting technical documentation shall include the items specified in paragraphs (b) through (k) of this section, as applicable to the specific rate adjustment filing. This information must be supported by workpapers in which all calculations are shown and all relevant values (e.g., rates, CPI-U values, billing determinants) are identified with citations to original sources. The information must be submitted in machine-readable, electronic format. Spreadsheet cells must be linked to underlying data sources or calculations (not hard-coded), as appropriate.

(b) The maximum rate adjustment authority, by class, as summarized by § 3030.127 and calculated separately for each of subparts C through H of this part, as appropriate.

(c) A schedule showing the banked rate adjustment authority available, by class, and the available amount for each of the preceding 5 years calculated as required by subpart H of this part.

(d) The calculation of the percentage change in rates, by class, calculated as required by § 3030.128.

(e) The planned usage of rate adjustment authority, by class, and calculated separately for each of subparts C through H of this part, as appropriate.

(f) The amount of new unused rate adjustment authority, by class, if any, that will be generated by the rate adjustment calculated as required by subpart H of this part, as applicable.

(g) A schedule of the workshare discounts included with the planned rate adjustments, and a companion schedule listing the avoided costs that underlie each such discount.

(h) Whenever the Postal Service establishes a new workshare discount rate, it must include with its filing:

(1) A statement explaining its reasons for establishing the workshare discount;

(2) All data, economic analyses, and other information relied on to justify the workshare discount; and

(3) A certification based on comprehensive, competent analyses that the discount will not adversely affect either the rates or the service levels of users of postal services who do not take advantage of the workshare discount.

(i) Whenever the Postal Service establishes a new discount or surcharge rate it does not view as creating a workshare discount, it must include with its filing:

(1) An explanation of the basis for its view that the discount or surcharge rate is not a workshare discount; and

(2) A certification that the Postal Service applied accepted analytical principles to the discount or surcharge rate.

(j) Whenever the Postal Service includes a rate incentive with its planned rate adjustment, it must include with its filing:

(1) Whether the rate incentive is being treated under § 3030.128(f)(2) or under § 3030.128(f)(1) and (g);

(2) If the Postal Service seeks to include the rate incentive in the calculation of the percentage change in rates under § 3030.128(f)(2), whether the rate incentive is available to all mailers equally on the same terms and conditions; and

(3) If the Postal Service seeks to include the rate incentive in the calculation of the percentage change in rates under § 3030.128(f)(2), sufficient information to demonstrate that the rate incentive is a rate of general applicability, which at a minimum includes: The terms and conditions of the rate incentive; the factors that determine eligibility for the rate incentive; a statement that affirms that the rate incentive will not benefit a single mailer; and a statement that affirms that the rate incentive is not only available upon the written agreement of both the Postal Service and a mailer, or group of mailers, or a foreign postal operator.

(k) For each class or product where the attributable cost for that class or product exceeded the revenue from that class or product as determined by the Commission, a demonstration that the planned rate adjustments comply with the requirements in subpart G of this part.

(a) The Commission will establish a docket for each rate adjustment filed by the Postal Service under § 3030.121, promptly publish notice of the filing in the Federal Register, and post the filing on its website. The notice shall include the items specified in paragraphs (b) through (g) of this section.

(b) The general nature of the proceeding.

(c) A reference to legal authority under which the proceeding is to be conducted.

(d) A concise description of the planned changes in rates, fees, and the Mail Classification Schedule.

(e) The identification of an officer of the Commission to represent the interests of the general public in the docket.

(f) A period of 30 days from the date of the filing for public comment.

(g) Such other information as the Commission deems appropriate.

Public comments should focus on whether planned rate adjustments comport with applicable statutory and regulatory requirements.

(a) If the Commission determines that the rate adjustment filing does not substantially comply with the requirements of §§ 3030.122 and 3030.123, the Commission may:

(1) Inform the Postal Service of the deficiencies and provide an opportunity for the Postal Service to take corrective action;

(2) Toll or otherwise modify the procedural schedule until such time the Postal Service takes corrective action;

(3) Dismiss the rate adjustment filing without prejudice; or

(4) Take other action as deemed appropriate by the Commission.

(b) Within 21 days of the conclusion of the public comment period the Commission will determine whether the planned rate adjustments are consistent with applicable law and issue an order announcing its findings. Applicable law means only the applicable requirements of this part, Commission directives and orders, and 39 U.S.C. 3626, 3627, and 3629.

(c) If the planned rate adjustments are found consistent with applicable law, they may take effect.

(d) If the planned rate adjustments are found inconsistent with applicable law, the Commission will notify and require the Postal Service to respond to any issues of noncompliance.

(e) Following the Commission's notice of noncompliance, the Postal Service may submit an amended rate adjustment filing that describes the modifications to its planned rate adjustments that will bring its rate adjustments into compliance. An amended rate adjustment filing shall be accompanied by sufficient explanatory information to show that all deficiencies identified by the Commission have been corrected.

(f) The Commission will allow a period of 10 days from the date of the amended rate adjustment filing for public comment.

(g) The Commission will review the amended rate adjustment filing together with any comments filed for compliance and issue an order announcing its findings within 21 days after the comment period ends.

(h) If the planned rate adjustments as amended are found to be consistent with applicable law, they may take effect. However, no amended rate shall take effect until 45 days after the Postal Service transmits its rate adjustment filing specifying that rate.

(i) If the planned rate adjustments in an amended rate adjustment filing are found to be inconsistent with applicable law, the Commission shall explain the basis for its determination and suggest an appropriate remedy. Noncompliant rates may not go into effect.

(j) A Commission finding that a planned rate adjustment is in compliance with the applicable requirements of this part, Commission directives and orders, and 39 U.S.C. 3626, 3627, and 3629 is decided on the merits. A Commission finding that a planned rate adjustment does not contravene other policies of 39 U.S.C. chapter 36, subchapter I, is provisional and subject to subsequent review.

(a) The maximum rate adjustment authority available to the Postal Service for each class of market dominant mail is limited to the sum of the percentage points developed in subparts C through E and G through H of this part.

(b) For any product where the attributable cost for that product exceeded the revenue from that product as determined by the Commission, rates may not be reduced.

(a) For the purpose of calculating the percentage change in rates, the current rate is the rate in effect at the time of the rate adjustment filing under § 3030.121 with the following exceptions:

(1) A seasonal or temporary rate shall be identified and treated as a rate cell separate and distinct from the corresponding non-seasonal or permanent rate. When used with respect to a seasonal or temporary rate, the current rate is the most recent rate in effect for the rate cell, regardless of whether the seasonal or temporary rate is available at the time of the rate adjustment filing.

(2) When used with respect to a rate cell that corresponds to a rate incentive that was previously excluded from the calculation of the percentage change in rates, the current rate is the full undiscounted rate in effect for the rate cell at the time of the rate adjustment filing, not the discounted rate in effect for the rate cell at such time.

(b) For the purpose of calculating the percentage change in rates, the volume for each rate cell shall be obtained from the most recently available 12 months of Postal Service billing determinants with the following permissible adjustments:

(1) The Postal Service shall make reasonable adjustments to the billing determinants to account for the effects of classification changes such as the introduction, deletion, or redefinition of rate cells. The Postal Service shall identify and explain all adjustments. All information and calculations relied upon to develop the adjustments shall be provided together with an explanation of why the adjustments are appropriate.

(2) Whenever possible, adjustments shall be based on known mail characteristics or historical volume data, as opposed to forecasts of mailer behavior.

(3) For an adjustment accounting for the effects of the deletion of a rate cell when an alternate rate cell is not available, the Postal Service should adjust the billing determinants associated with the rate cell to 0. If the Postal Service does not adjust the billing determinants for the rate cell to 0, the Postal Service shall include a rationale for its treatment of the rate cell with the information required under paragraph (b)(1) of this section.

(c) For a rate adjustment that involves a rate increase, for each class of mail and product within the class, the percentage change in rates is calculated in three steps. First, the volume of each rate cell in the class is multiplied by the planned rate for the respective cell and the resulting products are summed. Second, the same set of rate cell volumes is multiplied by the corresponding current rate for each cell and the resulting products are summed. Third, the percentage change in rates is calculated by dividing the results of the first step by the results of the second step and subtracting 1 from the quotient. The result is expressed as a percentage.

(d) For rate adjustments that only involve a rate decrease, for each class of mail and product within the class, the percentage change in rates is calculated by amending the workpapers attached to the Commission's order relating to the most recent rate adjustment filing that involved a rate increase to replace the planned rates under the most recent rate adjustment filing that involves a rate increase with the corresponding planned rates applicable to the class from the rate adjustment filing involving only a rate decrease.

(e) The formula for calculating the percentage change in rates for a class, described in paragraphs (c) and (d) of this section, is as follows:

(f)(1) Rate incentives may be excluded from a percentage change in rates calculation. If the Postal Service elects to exclude a rate incentive from a percentage change in rates calculation, the rate incentive shall be treated in the same manner as a rate under a negotiated service agreement (as described in paragraph (g) of this section).

(2) A rate incentive may be included in a percentage change in rates calculation if it meets the following criteria:

(i) The rate incentive is in the form of a discount or can be easily translated into a discount;

(ii) Sufficient billing determinants are available for the rate incentive to be included in the percentage change in rate calculation for the class, which may be adjusted based on known mail characteristics or historical volume data (as opposed to forecasts of mailer behavior);

(iii) The rate incentive is a rate of general applicability; and

(iv) The rate incentive is made available to all mailers equally on the same terms and conditions.

(g)(1) Mail volumes sent at rates under a negotiated service agreement or a rate incentive that is not a rate of general applicability are to be included in the calculation of the percentage change in rates under this section as though they paid the appropriate rates of general applicability. Where it is impractical to identify the rates of general applicability (e.g., because unique rate categories are created for a mailer), the volumes associated with the mail sent under the terms of the negotiated service agreement or the rate incentive that is not a rate of general applicability shall be excluded from the calculation of the percentage change in rates.

(2) The Postal Service shall identify and explain all assumptions it makes with respect to the treatment of negotiated service agreements and rate incentives that are not rates of general applicability in the calculation of the percentage change in rates and provide the rationale for its assumptions.

(a) The Postal Service may request that the Commission review a de minimis rate increase without immediately calculating the maximum rate adjustment authority or banking unused rate adjustment authority. For the exception in this paragraph (a) to apply, requests to review de minimis rate adjustments must be filed separately from any other request to review a rate adjustment filing.

(b) Rate adjustments resulting in rate increases are de minimis if:

(1) For each affected class, the rate increases 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 rate adjustment resulting in a rate increase, or the most recent rate adjustment due to extraordinary and exceptional circumstances, 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.

(c) If the rate adjustments are de minimis, no unused rate adjustment authority will be added to the schedule of banked rate adjustment authority maintained under subpart G of this part as a result of the de minimis rate increase.

(d) If the rate adjustments are de minimis, no rate decreases may be taken into account when determining whether rate increases comply with paragraphs (b)(1) and (2) of this section.

(e) In the next rate adjustment filing proposing to increase rates for a class that is not a de minimis rate increase:

(1) The maximum rate adjustment authority 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.

(f) The Postal Service shall file supporting workpapers with each request to review a de minimis rate increase that demonstrate that the sum of all rate increases included in de minimis rate increases since the most recent rate adjustment resulting in a rate increase that was not de minimis, or the most recent rate adjustment due to extraordinary and exceptional circumstances, does not result in a percentage change in rates for the class equaling or exceeding 0.001 percent.

(g) For any product where the attributable cost for that product exceeded the revenue from that product as determined by the Commission, rates may not be reduced.
