Subject of Possible Rule Making: SWAPCA 491, Emission Standards and Controls for Sources Emitting Gasoline Vapors.

Statutes Authorizing the Agency to Adopt Rules on this Subject: RCW 70.94.141.

Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: The Washington state rule on this subject chapter 173-491 WAC was revised in December 1997 to incorporate the requirements of SHB 2376. SWAPCA 491 needs to be updated consistent with SHB 2376 and chapter 173-491 WAC. In addition, SWAPCA has been coordinating with Oregon DEQ to establish vapor control requirements for gasoline barge loading activities. Oregon DEQ has a draft rule that has been negotiated with sources in the Vancouver/Portland area. SWAPCA is proposing to adopt similar language to that of Oregon DEQ so as not to create an economic advantage.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: SWAPCA partnered with the Washington Department of Ecology in making the changes necessary for chapter 173-491 WAC. SWAPCA has also partnered with Oregon DEQ in proposing new rules for gasoline barge loading and lightering activities for sources on the Columbia and Williamette rivers.

Process for Developing New Rule: Negotiated rule making.

Interested parties can participate in the decision to adopt the new rule and formulation of the proposed rule before publication by contacting Paul Mairose by telephone at (360) 574-3058 ext. 30 or by mail at 1308 N.E. 134th Street, Vancouver, WA 98685.
