1. Program Update – Oregon Pesticide Symposium Kevin Masterson, Oregon DEQ masterson.kevin@deq.state.or.us Pesticide Stewardship Partnership Program: Protecting Water Quality through Collaboration

2. Monitor for current use pesticides in surface waters from drift & runoff Identify streams with elevated pesticide concentrations or high # of detections Collaborate to implement voluntary management practices Follow-up monitoring to determine improvements over time Pesticide Stewardship Partnerships (PSPs) Collaborating at the watershed level Key Steps in Partnership Projects

3. “Non-Point” Pesticide Water Quality Risks Multiple Use Sites Rural  Forestry  Right-of-way  Recreation  Landscaping  Urban  Homes

5. Water monitoring sites often from atop or below roadway bridges - Runoff from roadway and adjacent land use activities

6. Coordinate to prevent / reduce… Currently registered pesticides in… Surface and groundwater resulting from… Agricultural and non-Agricultural uses Awareness & Voluntary Collaborative Solutions 2007 Water Quality Pesticide Management Team Collaborative Inter-Agency Approach

7. + Local List (OR) 16 Additional Pesticides National List (EPA) 57 Pesticides of Interest 73 “Pesticides of Interest” (POIs) Smaller List of “Pesticides of Concern” (POCs) Oregon Pesticides of Interest (POIs) Selection Factors Pesticide properties persistence, toxicity, etc. Use (what, where, when) Historical detections Other “weight-of-evidence” Needs Updating! Last Revised in 2012-13

8. New PSP Program Developments: Program Expansion and Evolution

9. Pesticide-related Water Quality Management: Stable Funding for PSP Program 2013 Oregon Legislature allocated resources to: 1.To add new watersheds to program and support & enhance monitoring in existing PSP watersheds 2.To conduct pesticide waste collection events during biennium (7-10 events over two years). 3.To provide stewardship technical assistance support Similar 2015-17 Legislative Allocation ($1.695m): Continued surface water monitoring, and some sediment monitoring in 9 watersheds 3 collection events in Eastern Oregon in Fall 2015, and several more planned in 2016-17 Multiple local technical assistance grant proposals funded PSP “Partner” grants to support sample collection & outreach

10. 2016 Pesticide Stewardship Partnerships: 9 Oregon Watersheds 2014-15 Pilot Monitoring in: Middle Rogue Middle Deschutes South Umpqua South Coast Newest PSP – 2016 baseline monitoring underway Recent Program Emphasis: Ensure a diverse array of land uses are represented

11. PSP Monitoring Data: Successes and 2015 Data Findings

12. (86%) (19%) Cherry growers increasing use of weather stations to reduce wind drift & use more ground (rather than aerial) spraying near streams Only 2 weeks of monitoring in 2010 malathion use season

13. Max = 18.9 ug/l Max < 0.1 ug/l In 2012, irrigation district switched to mechanical weed controls and spot spraying of a less toxics and persistent herbicide

14. Clackamas Watershed PSP Program (2014) The Oregonian, December 1, 2014

16. What Types of Actions Have Been Implemented to Produce Results? Spray Drift Reduction Trainings & Practices Installation of Weather Stations Use of Biological Controls (e.g., mating disruption) Integrated Pest Management Training & Technical Assistance Use of Less Toxic Pesticides Buffer Strips & Minimize Spraying near Streams

18. Evaluation of Monitoring Data by Inter-Agency Team 2. Aquatic Life Ratio: Detected Concentration (ug/L) / Lowest Acute or Chronic ALB  Values ≥ 1.0 indicate a potential concern and need for further attention 3. Other “weight-of-evidence” factors: Frequency of detections, number of pesticides in a single sample (mixtures) Rainbow trout Fathead minnow Bluegill sunfish Green algae Daphnia magna Duckweed 1.Compare Detections to EPA Aquatic Life Benchmarks (ALB) Most sensitive acute & chronic toxicity data for each group of organisms Non-regulatory values that help ID & prioritize pesticides & locations 0.45 ug/L2.4 ug/L 0.041 ug/L Chlorpyrifos (chronic fish) Diuron (acute non-vascular) Bifenthrin (chronic invertebrate) 0.0013 ug/L Imazapyr (acute vascular) Sulfometuron methyl (acute vascular) 24 ug/L
