WASHINGTON STATE'S 'PURPLE BOOK' GUIDANCE MANUAL FOR THE NEW RECLAIMED WATER RULE

摘要

Washington State began a rulemaking process in 2006 to update and to convert the 1997 Water Reclamation and Reuse Standards (Washington State Department of Ecology, 1997) into a regulation, the Reclaimed Water Rule, Chapter 173-219 Washington Administrative Code (Washington State Department of Ecology, 2010). The Rule is intended to provide a consistent and efficient regulatory process, yet be flexible enough to stand the test of time. The Rule refers to a Reclaimed Water Facilities Manual, a.k.a. the "Purple Book," for supplemental guidance on implementing the Rule. Gray & Osborne, Inc. was retained by the Washington Coalition for Clean Water and the Washington State Department of Ecology (Ecology) to assist in development of the manual, which has been released for review by stakeholders. Rule adoption and publication of the Purple Book are anticipated in 2013.
