Protection of Stratospheric Ozone: Additional Reconsideration of Petition Criteria and Incorporation of Montreal Protocol Decisions

요약

With this action, EPA is making minor revisions to the accelerated phaseout regulations that govern the production, import, export, transformation and destruction of substances that deplete the ozone layer under the authority of Sections 604, 605, 606, and 614 of Title VI of the Clean Air Act Amendments of 1990 (CAA or the Act). As part of this action, EPA is clarifying the petition process for imports of used class I controlled substances. Today's amendments also reflect changes in U.S. reporting obligations under the Montreal Protocol on Substances that Deplete the Ozone Layer (Protocol) due to a recent decision by countries that are Parties to this international agreement. Additionally, in response to a petition submitted to EPA, the Agency is removing the requirement in the petition process for imports of used class I controlled substances that a person must certify knowledge of tax liability.
