Pesticide Stewardship Partnership Program Protecting Water Quality through

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

Pesticide Stewardship Partnerships (PSPs) Collaborating at the watershed level Key Steps in Partnership Projects 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

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

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

New PSP Program Developments: Program Expansion and Evolution

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. 695 m): • • 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 &

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

PSP Monitoring Data: Successes and 2015 Data Findings

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

Max = 18. 9 ug/l In 2012, irrigation district switched to mechanical weed controls and spot spraying of a less toxics and persistent herbicide Max < 0. 1 ug/l

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

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

Evaluation of Monitoring Data by Inter-Agency Team 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 Rainbow trout Fathead minnow Bluegill sunfish Daphnia magna Green algae Duckweed 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) Bifenthrin (chronic invertebrate) Sulfometuron Diuron Chlorpyrifos methyl (acute (chronic (acute non-vascular) fish) vascular) 0. 0013 ug/L 0. 041 ug/L 0. 45 ug/L 2. 4 ug/L Imazapyr (acute vascular) 24 ug/L
