Oregon Aquatic Weed Control: Discussion on permits, consultations, & regulations Vanessa Morgan Center for Lakes and Reservoirs Aquatic Weed Workshop Salem, Oregon April 24, 2014

Overview Rationale for regulations, permits, reviews, etc. Waterbodies (ponds, lakes, streams, rivers, estuaries) Weeds in water and/or wetlands –Potential impacts of control methods –Potential impacts of choosing to not control Agencies & various control methods Gray areas – opportunities for clarification, streamlining, coordination

Why regulate? Multiple beneficial uses –Agriculture –Domestic –Industry –Flood protection –Filtering pollutants –Habitat for aquatic life Pressure/stressors: –Periodic droughts, climate change, invasive species

Waters of the State (Dept. of State Lands) State ownership of submerged and submersible land underlying navigable waterways (streams, rivers, lakes), tidally influenced waterways and the Territorial Seastreams, riverslakestidally influenced waterways Navigable: Used or susceptible to use at time of statehood (1859) in its natural and ordinary condition for commerce/trade/travel by a customary mode of trade and travel (canoes, fishing, recreation, log drives, etc.) All meandered lakes are declared to be navigable and public waters (~75 to 90) Sections of 12 rivers determined to be navigable TypeJurisdictional Limit Pacific OceanExtreme low tide to 3 mi out Tidal bays & estuariesHMT or upper edge of wetland Perennial streams, lakes, ponds OHW Intermittent streamsOHW WetlandsWetland boundary Artificial ponds, ditchesOHW Artificial wetlandsWetland boundary ReservoirsNormal operating pool level or upper edge of adjacent wetland

U.S. Army Corps of Engineers Regulatory Jurisdiction

Potential impacts of control efforts Turbidity Non-target animals/plants Increased germination Algae issues New invasives MN Dept. of Natural Resources

Impacts of no-control efforts Recreation  Flooding  Irrigation  Diversity  Fire  Property values

Oregon Dept. of State Lands Wetland Program –Wetland determination, to determine potential need for wetland delineation Wetlands/Waterways Removal-Fill Program –Oregon’s removal-fill law (ORS ) Land Management Division –Written approval of uses of, and structures occupying, state-owned land (e.g. remediation, restoration, or “special uses”)

Oregon Dept. of Environmental Quality NPDES 2300-A Pesticide General Permit –pesticide applications in, over, or near water to control: Aquatic weeds and algae, nuisance animals, mosquito control, forest canopy pests, area-wide pests Vegetation, algae, pathogens, fungi in water or at water’s edge (within 3 horizontal feet) –Registration required for Federal & state agencies, Districts responsible for pest control, or Large scale applications (threshold: 20 acres or 20 linear miles) –Permit requirements: pesticide discharge management plan, follow detailed pest management measures, keep additional records, and submit an annual report

Oregon Dept. of Environmental Quality NPDES 2300-A Pesticide General Permit –Registration not required for small scale applications (below thresholds) by individuals, businesses, or property owners responsible for applications –However, all operators required to keep a copy of the permit and follow basic requirements no violations of water quality standards, minimize use, corrective actions, environmentally sensitive approach Monitoring, notification, reporting adverse incidents, etc. Records retained for 3 years

ODFW Helps to designate ESH (with DSL) Oregon Guidelines for Timing of In-water Work to Protect Fish & Wildlife Resources to minimize impacts to fish, wildlife and habitat resourcesOregon Guidelines for Timing of In-water Work to Protect Fish & Wildlife Resources Grass Carp Permits

U.S. Army Corps of Engineers Authorities: Section 10 of the Rivers and Harbors Act of 1899 –governs work impacting navigable waters; e.g. dredging or excavation Section 404 of the Clean Water Act –regulates placement or fill material into waters of the state –grading or clearing of wetlands Section 103 of the Marine Protection, Research and Sanctuaries Act –ocean discharges of dredged materials Permits: Individual Permits (standard or letter of permission) General Permits (Nationwide or Regional) –Potentially under reauthorization of RGP-04 Aquatic Habitat Restoration in Oregon (USFS & BLM land only)

Oregon Dept. of Agriculture Pesticide Program –Product registration –Licensing & recertification Plant Division – Noxious Weed Program –Coordination & management of noxious weeds –Biocontrol Program Oregon State Weed Board – state weed priorities, grant program, noxious weed listOregon State Weed Board Plant Division – Plant Conservation –Public land action permits (or formal consultation) required for any taking (or potential taking) of any state-listed T&E species on non-federal public lands Threatened State-listed plant Nelson's checkermallow (Sidalcea nelsoniana) A-listed Noxious weed yellow floating heart (Nymphoides peltata)

NOAA Fisheries & USFWS ESA Section 7 consultations –NMFS consultations on salmon, marine fish, marine mammals and marine reptiles –USFWS consultations regarding birds, terrestrial animals, plants, amphibians and most freshwater fish

Manual Removal (hand removal, raking) In jurisdictional waters: DSL Removal-fill permit required for where: > 50 cu yds of either removal and/or fill, or Any amount of removal or fill in ESH, SSW, or compensatory mitigation sites –Exception: non-motorized removal that disturbs less than 1 cu. yard of sediment (3” disturbance 108 sq. ft.) ODFW preferred in-water work periods Removal inorganic; Calculated on annual basis Fill organic or inorganic below OHW; Calculated on a cumulative basis

Mechanical Removal (harvesting, rotovation, dredging) In jurisdictional waters: DSL Removal-fill permit required for where: > 50 cu yds of either removal and/or fill, or Any amount of removal or fill in ESH, SSW, or compensatory mitigation sites ODFW preferred in-water work periods USACE permit - maybe? –Section 10 (work impacting navigable waters) and/or –Section 404 (placement or fill material; grading or clearing of wetlands)

Benthic Barriers DSL Removal-fill permit required in ESH, SSW, or compensatory mitigation sites for any amount of fill or removal U.S. Army Corps of Engineers –Placement or discharge of dredged or fill material into waters of the United States (Section 404 of the CWA) –Possibly under Regional General Permit-04 (Aquatic Restoration in Oregon)? Only pertains to USFS and BLM lands Currently no mention of benthic barriers, but undergoing reauthorization with some changes

Chemical Control Surface, subsurface or riparian/emergent treatments in, over or within 3 ft. of water NPDES general water quality permit (2300-A) All label requirements; including any necessary –notification of water suppliers near potable water –Residue testing and all other use-restrictions (fishing, swimming, irrigation, etc.) ODA Pesticide Program –Appropriate license & aquatic category –Use of approved aquatic formulations registered for use in Oregon

Biological Control Sterile triploid grass carp ( Cteneropharyngodon idella ) –ODFW permit required Approved screening (inlets & outlets) Private land – restricted public access Ponds or lakes < 10 acres; canals, ditches 100-yr floodplain Stocking limit 22 fish/acre; PIT-tagged Insects (milfoil weevil, purple loose strife agents)

Sterile triploid grass carp Insects (milfoil weevil, purple loose strife agents) –APHIS - PPQ 526 permit is required for any “importation, interstate movement and environmental release of biological control organisms” 8 wks – 18 mo. –ODA Biocontrol Agent Release Form – recommended, not required Biological Control

Improvements? Where is there room or need for: Clarification Streamlining Improved coordination Outreach
