Introduction and Expectations:

This is the first meeting of the Technical Advisory Panel (TAP). The TAP formed in response to input from the Reclaimed Water Rule Advisory Committee (RAC) at their November 2007 meeting. Members introduced themselves and included their expectations for the group.


Kathy Cupps (Ecology) summarized a few key points for rule development:

Technical Advisory Panel (TAP) Role

Ecology provided copies of 1997 Technical Standards, Design Criteria, related regulations and statutes, and handouts from the Rule Advisory Committee (RAC).

Ecology has been working with the Rule Advisory Committee (RAC) since the fall of 2006. At the November 2007 RAC meeting, members agreed that a subgroup of experts would be helpful to consider technical details. PNCWA volunteered to help in this effort and with the RAC direction, Ecology created the TAP. The TAP will provide information and make technical recommendations to the RAC. The RAC remains the advisory committee to Ecology for the rule. Ecology has the task of writing the rule. The rule also goes through a public review and comment period.

Washington is one of the few states that have a statute with a mandate to develop regulations defined so broadly. Uses include commercial and industrial, irrigation (both urban and agricultural), ground water recharge, streamflow augmentation and wetlands creation and enhancement. We want the regulation to be as clear and easy to use as possible.

Ecology is unsure as to how much time and effort the TAP members are able to devote to this task. This will be a determining factor in developing the scope of work so main task for today is to determine a practical scope of work and plan.


The TAP discussed (in a brainstorm session) various ways in which they could help Ecology and RAC.

Key points:

  • Meet the intent of the legislature.
  • Look at what other states are doing but don’t incorporate rules from other states unless they make sense for Washington.
  • Define what goes into the new rule and what information becomes guidance.
  • Update requirements to protect public health.
  • Define the reclaimed water use, then what approach to recommend.
  • Consider how the rule will affect small businesses.
  • Important to spend time on groundwater issues.
  • Develop an approach for evaluation of reclaimed water use.
  • Should TAP break-up into smaller geographic or regional groups?
  • How should TAP provide recommendations to the Rule Advisory Committee?
  • Develop a white paper?
  • White paper should be the basis for new reclaimed water guidance.
  • Respond to Ecology white paper.
  • Multiple authors addressing single issues?
  • Collaboration with single author addressing all issues?
  • A roundtable discussion included the following comments and questions:

    Process Agreement

    The TAP attempted to apply a use-based approach to the rule framework using a proposed list of questions and urban irrigation in public areas as the example. The TAP encountered obstacles to this approach and decided to address some overarching issues before proceeding with use-based approach. The TAP agreed to use (try) the following process:

      1. Define general categories.

        a. Public health (pathogen requirements)

          Suggested levels to consider:

        1. Drinking water.

        2. Human contact.

        3. No contact with humans.

        b. Environmental protection requirements.

        Ecology provides a bulleted list of existing requirements.

        c. Suitability for the use (other factors).

      2. Develop use-based requirements (use-by-use).

      3. Look at issues of scale - small vs. larger systems.

      4. Determine if content should be in rule or guidance.

    Other Agreements

  • TAP members have limited time.

  • TAP product consists of recommendations to RAC on technical standards content.

  • Complete scope of work by October 1, 2008.

  • Schedule regular monthly meetings (or phone) for the next seven months.

  • May use telephone or geographic subgroups to support the efforts.

  • If meeting in person - full day. Phone or subgroups shorter timeframe.

  • Use 1997 standards as a starting point.

  • Understand what is and what is not working well.

  • Work to develop use based standards

  • Work to integrate requirements with existing Washington state regulations.

  • Consider the content and proposed direction for regulations in other states.

  • Action Items:


  • Scanned handouts on wetlands and direct recharge (documents A&B)

  • Links to regulations in other states.

  • Outline (framework) for technical standards with e-links to other regulations

  • Draft (suggested) work plan for TAP

  • Agenda for next meeting – March 2008
