EPA is taking direct final action to approve a revision to the State Implementation Plan (SIP) and Operating Permits Program to amend the definitions provisions of the rules by adding definitions for stage I/II vapor recovery systems and outstate area, updating the lists of volatile organic compounds and hazardous air pollutants for consistency with the Environmental Protection Agency (EPA) lists, removing unnecessary definitions, and making typographical corrections and clarifications. Approval of this revision will ensure consistency between the state and the Federally-approved rules.
