Details: SUMMARY: meeting with EPA and PWB re: OCCT DETAILS: We (Kari Salis, Dave Leland) had a meeting with EPA (Dan Opalski, Marie Jennings, Harold Rogers) and PWB (Mike Stuhr, Chris Wanner, Yone Akagi, Dave Peters, Kim Gupta, Scott Bradway) as proposed by PWB in their 3/21/16 letter to Dave Leland. The Water Bureau presented on the whole history and current state of the overall Lead Hazard Reduction Program, including corrosion control treatment of the water supply. Highlights of presentation and discussions:1. Portland started work on a consultant-lead internal corrosion study in May 2014, which includes a detailed one-year field study during 2016 of characteristics of internal corrosion of Portland water on various plumbing materials under controlled conditions in the distribution system2. PWB/EPA/OHA to meet again in August (date TBD), where PWB will present the initial results of the corrosion field work, and present to EPA/OHA a detailed proposed schedule for selection, design, construction, and implementation of optimized corrosion control treatment of the drinking water supply as per EPA regulations.3. Portland is currently updating their public communication on lead in drinking water, including increased outreach to specific vulnerable populations.4. EPA was very clear that current lead levels at the tap arenít good enough, and they expect Portlandís schedule for implementing optimized corrosion control to be aggressively timed, with option for renegotiating if external barriers emerge, such as land use approvals, etc.5. PWBs intent is to maintain commitment to its Lead Hazard Reduction Program efforts, even with further treatment of the water supply. ACTION NEEDED: further discussions as needed, meet in summer 2016.
