Region 10 AWOP Planning Meeting: June 19 – 20, 2012

The Region 10 AWOP group conducted a strategic planning meeting in June using Adobe Connect and conference call facilities.  Participants included representatives from Alaska, Oregon, Washington, EPA Region 10, ASDWA, TSC, and PAI.  State AWOP reports included a discussion by Alaska on applications for their completed water system Status Component Inspections. Completing the inspections at all of their surface water systems was a large undertaking given the size and geography of the state. Benefits of this effort include targeting appropriate plants for CPEs and training and use of the information by local funding agencies to prioritize system modifications.  Oregon reported on their development of a data integrity work group to investigate ways to incorporate data integrity into operator training and outreach.  Washington discussed the success of their optimization awards program.  Since its inception in 2009, they have awarded a total of 38 award certificates to 26 different systems.  This represents 41% of the total number of plants in the state.

The group identified and discussed several AWOP topics related to priorities and issues in the region.  Washington and EPA Region 10 discussed the results of their successful multi-state microbial CPE that was conducted in Ilwaco, WA in early June.  Washington plans to continue to build in-house capability to conduct future CPEs at their rapid rate filtration plants.  Progress continues to be made on developing optimization criteria for slow sand and membrane filtration systems.  Several national slow sand filtration experts have provided comments on the proposed goals.  Future membrane filtration system activities planned by the group include identifying membrane systems to work with one-on-one to gain a better understanding of key operating and performance parameters and a possible multi-day field event hosted by Oregon in 2013.  Washington discussed their successful application of optimization principles to a small ground water system treating for arsenic removal using oxidation, coagulation, and filtration processes.

The fall AWOP meeting is scheduled for October 23 – 25, 2012 and will be hosted by EPA Region 10 in Seattle.  A turbidity data integrity field event is being planned at a local treatment plant.
