Air Quality State Implementation Plans - Approvals and Promulgations - Oregon - Revised Format for Materials Incorporated by Reference (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Air Quality State Implementation Plans - Approvals and Promulgations - Oregon - Revised Format for Materials Incorporated by Reference (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The EPA is revising the format for materials submitted by the State of Oregon that are incorporated by reference (IBR) into the Oregon State Implementation Plan (SIP). The regulations affected by this format change have all been previously submitted by the State of Oregon and approved by the EPA. This format revision will primarily affect the "Identification of plan" section, as well as the format of the SIP materials that will be available for public inspection at the National Archives and Records Administration (NARA), the Air and Radiation Docket and Information Center located at the EPA Headquarters in Oregon, DC, and the EPA Regional Office. The EPA is also adding a table in the "Identification of plan" section which summarizes the approval actions that the EPA has taken on the non-regulatory and quasi-regulatory portions of the Oregon SIP.
