P.R. Laws tit. 27, § 1261
(a) At any time that the Commission shall desire to issue a rule it shall notify its purpose to do so by serving notice upon all persons to whom the rule shall be applied, either personally or by mail or, when the number of persons exceeds fifty [(50], by publication in a newspaper of general circulation in Puerto Rico on two different dates. The notice shall include all such matters as the Commission may establish by rule. This subsection shall not apply in those cases in which the Commission shall find that there is good cause for which the notice and the public procedure are impracticable, unnecessary, or counter to the public interest, in which cases the Commission shall make the finding and a brief statement of the reasons therefor in the rules to be issued by it. No notice whatsoever shall be required prior to the issuance of interpretations of general application or of general orders having the force of law. Such statements and interpretations of general application, and rules of procedure, shall be made available to the public upon issue and shall be published annually.
(b) Upon service of the notice required by this section, the Commission shall give all interested persons the opportunity to participate in the procedure for the adoption of the rule, through the filing, in writing, of their viewpoints, data, or arguments, with or without the opportunity to express same verbally. After considering all relevant matters presented, the Commission shall incorporate into any rule adopted by it a brief general statement about its grounds and purposes. In those cases where this part requires that the opportunity of a previous hearing be granted for the adoption of a rule, the procedure provided in § 1260 of this title shall be followed instead of the provisions of this subsection.
(c) The publication or notice required by any substantive rule other than one granting or acknowledging an exemption or eliminating a restriction, shall be carried out not less than thirty (30) days in advance of the date on which the rule is to take effect, except where the Commission otherwise provides upon determining that there is good cause therefor, which shall be set forth at the time the rule is published.
(d) All interested persons shall have the right to request of the Commission that a rule be issued, amended, or repealed.
