Oregon Revised Statutes Utility Regulation § 757.526

No sooner than 90 days after the enactment of a federal law, state law, regulation or rule regulating the emission of greenhouse gases from generating facilities, an electric company, electricity service supplier or the customer of an electric company or electricity service supplier may petition the Public Utility Commission to study the greenhouse gas emissions standard established under ORS 757.524. If the commission undertakes the study, the commission shall determine whether the standard is still necessary to reduce greenhouse gases emitted by electric companies and electricity service suppliers and whether the standard should be repealed or maintained in whole or in part. In making the determination, the commission shall consider whether the enacted federal law, state law, regulation or rule is inconsistent with the standard or renders the standard redundant. The commission shall report the results of the study, and shall include recommendations for legislation, to the Legislative Assembly in the manner described in ORS 192.245 no later than 12 months after receiving the petition.
