Section 182 (b)(3) of the federal Clean Air Act required the implementation of Stage II vapor recovery in ozone nonattainment and maintenance areas, including northern Virginia and Richmond. Since then, in accordance with § 202(a)(6) of the Act, the U.S. Environmental Protection Agency (EPA) has determined that onboard refueling vapor recovery (ORVR) is in widespread use throughout the motor vehicle fleet, thus obviating the need to maintain Stage II vapor recovery programs. The department has examined whether Stage II is still necessary for ozone control purposes and has determined that Stage II is no longer needed. Removing this control requirement will not interfere with maintenance of any ozone standard. Therefore, on November 12, 2013 and March 18, 2014, the department submitted revisions to the state implementation plan (SIP) that satisfy all requirements of the federal Clean Air Act and EPA guidance regarding the removal of Stage II requirements from the northern Virginia and Richmond area attainment and maintenance plans. Virginia's specific Stage II requirements are found in Article 37 of 9VAC5-40, and must now be amended accordingly. |
