## Abstract

Pursuant to procedures described in the January 19, 1989 Federal Register, the Environmental Protection Agency (EPA or we) recently approved a minor State Implementation Plan (SIP) revision submitted by the Oregon Department of Environmental Quality (ODEQ). This submittal includes the following changes to the Oregon Administrative Rules (OAR) 340-028-0110 (Definitions): a revision of the definition of Volatile Organic Compounds (VOC), typographical corrections, updated reference dates, and the renumbering of several definitions. The VOC definition was revised to delist parachlorobenzotriflouride (PCBTF) and cyclic, branched, or linear completely methylated siloxanes from the definition of VOC. This document lists the revision we approved and incorporates the relevant material into the Code of Federal Regulations.
