St. Lawrence River AOC at Massena/Akwesasne Jessica L. Jock Saint Regis Mohawk Tribe (SRMT) Environment Division NYS AOC Meeting April 21, 2015
2010 SRMT GLRI Work Plan Objectives Make advancements on the BUIs of the St. Lawrence River AOC at Massena/Akwesasne Restrictions on fish and wildlife consumption (I) Loss of fish and wildlife habitat (I) Degradation of fish and wildlife populations (U/NFA) Bird or animal deformities or reproductive impairments (U/NFA) Fish Tumors or other deformities (U/NFA) Degradation of benthos (U/NFA) I = Impaired, U/NFA = Unknown/Need Further Assessment
October 2010-September 2015 BUI Advancement Fish Tumor Study Furbearer Mammal Study Turtle Study Avian Study Freshwater Mussel Study** Lake Sturgeon Restoration** Lake sturgeon health assessment Spawning riffle habitat reconnaissance Hydrodynamic and bathymetry characterization in 2-selected riffles Design/Permitting/Placement ** SRMT work contributed to 2015 studies to be conducted by Alcoa, and USGS

2012 Secondary Data Review of Historical Turtle Tissue Studies Harper, L.H., G. Johnson, and J.L. Jock. June 2014. Turtle interim status report. Secondary data review of the Massena Akwesasne St. Lawrence River Area of Concern (AOC). GL-9722130-10. 54pp.
2013 Field Study Objectives: Determine contaminant burdens (PCBs, dioxin/furans, organchlorine pesticides, Hg, fluoride, aluminum) inside and outside the AOC Determine if healthy, self-sustaining populations are present inside and outside the AOC Determine rate of deformities and hatching success inside and outside the AOC Determine the extent and suitability of appropriate habitat inside and outside the AOC Habitat, Populations, Contaminants
2013 Field Study Methods Habitat: GIS Analysis of wetlands inside and outside the AOC along four rivers Habitat Suitability Index (HIS) Model based on field measurements Populations: Visual and Trap-based Rapid Assessment (TRA) Contaminants and deformities: examine captured turtles; locate, collect, and test eggs for contaminants; incubate eggs in lab to examine hatchlings
Habitat, GIS Analysis: Outside AOC
2013 Contaminant Analysis 33 Egg Samples Collected
Contaminants in Snapping Turtle Eggs: Grasse R. Contaminant (ng/g) (ppb) Total PCBs Grasse River Inside AOC Outside AOC n=4 n=4 650 ± 820 (4)* 4 ± 3 (4)*
Turtle Trapping
2014 Avian Tasks Monitor colonial waterbirds and sentinel species nesting inside and outside the AOC Species included Black Tern, Common Tern, Herring Gull, Osprey, and Bald Eagle Qualitatively assess habitat Determine productivity (chicks fledged per nest) Collect eggs of selected species at selected sites for contaminant analysis (PCBs, dioxin/furans, pesticides, Hg, metals)
Year 2013 (16 sites) Nests Black Tern Nests in Snye Marsh Eggs or Chicks Eggs or Chicks per Nest Notes 74 163 eggs 2.2 eggs nest 1 eggs only 2014 (10 sites) 78 40 chicks 20 40 0.5 chicks nest 1 2.0 chicks nest 1 all nests nests with chicks
