5/10/2012 Project History - Existing Discharge Regulatory - TMDL Umatilla River TMDL Summer  Established in 2001  Class C Recycled  Temperature, sediment, aquatic weeds, algae, Water pH, ammonia, bacteria  LGW Ranch Meet all permit conditions except: LGW Ranch River Discharge Winter 570 acres  Ammonia  Umatilla River  Temperature (TMDL & WQ Standard) Regulatory - Ammonia Regulatory - Temperature  Current outfall location does not provide Temperature enough flow or dilution to meet new Non-Compliance stringent permit limits  Ammonia standard for Umatilla River is the lowest in the State of Oregon  Fish Use drives compliance in the Umatilla River Temperature Standard River Temperature Regulatory - Future Regulations Getting to a Solution The City is planning ahead in Challenges Potential Solutions anticipation of future water quality  TMDL  Facility upgrades regulations to protect salmon fisheries  Ammonia  MBR technology  Fish consumption rate increase  Temperature  Minimize discharge  Senate Bill 737  Future Regulations  Class A Recycled  Turbidity Water  ‘Hot bed’ of tribal,  Nutrient standards regulatory, political  Forge new  Mixing zone challenges influences partnerships  Costs 2

5/10/2012 Solution – Screeching Halt Solution – Screeching Halt Solution – UAA Solution – Screeching Halt Use Attainability Analysis  Regulatory process that authorizes changing designated uses that in State water quality standards  ~200 since the CWA was promulgated  10 related to temperature  None in the Pacific Northwest  Can take 2-4 years to complete! Solution – UAA Solution – Help Make UAA Successful Scientific Understanding Regulatory Legal and Agency Regulatory Preparedness Understanding Successful UAA Process Financial Needs and Public Awareness Impacts Adapted from WERF, 2007 4

5/10/2012 Solution – Help Make UAA Successful Solution – Help Make UAA Successful Fish NPDES Approach based on Irrigation Beneficial Use  Fish Screens of intake and Pump Stations  Fish Passage Barrier at outlet to Columbia River  Establish Beneficial Use in the Evaluation Report  No Fish Present in Canal  Document Oregon DFW support for no fish  Establish WEID/USBR policies on water use Drinking Water  Prohibited By Law Establish Mixing Zone in the Canal  Over 2 Miles to First Withdrawal Point Fish Contact Recreation  Prohibited Existing NPDES  Herbicide applications – Acrolein Solution – Success…Almost There  One additional & existing stakeholder  Recycled Water in Summer  Drought proof supplemental supply for WEID Questions?  Approximately 600 acres (1,800 Acre-Feet)  Reduced pumping costs & energy savings  Establishes Precedent with USBR, EPA, DEQ Mark Cullington  High Quality Winter Discharge  Protects cold water habitat markcullington@kennedyjenks.com  Highest quality recycled water (503) 423-4043  Proactive – Anticipates futures toxics reduction regulations 5
