They must also report modifications to charges. Reductions in fees and/or charges will be reported within thirty (30) consecutive days following their application. PSPCP and OPNFC shall only submit the requested information in Sections B and D -where applicable- detailed in these procedural rules.

In the case of information on “rates”, it must be reported -according to specific instructions for each included product- the rate in effect on the last business day of the month immediately preceding the submission month (e.g., a submission due on the tenth business day of month n will contain rates in effect on the last day of month n-1). The due date for submitting this information will operate on the 10th (tenth) business day of the reported month and will correspond to the tariff schedule in effect during the following month. Monthly information is composed as follows: Section A: “Information on named tariff schedule”. Section B: “Information on complete tariff schedule”.
