Objectives of Review

Compile information on: Status of the Great Lakes relative to chemicals listed in Annex 1 Relationship of current policy values to Specific Objectives Conceptual basis and rationale for current policy values How each agency assesses compliance with their policy values for open waters of the Great Lakes

4 Caveat

Caveat

Not exhaustive compilation of all data available Data do not represent comprehensive spatial or temporal coverage Data were assumed to meet QA/QC requirements Did not interview every agency with a regulatory mandate in the Great Lakes Comments related to key omissions are welcomed - Report is a draft

9 Comparison to Most Recent Field Data

Comparison to Most Recent Field Data

Screening-level comparison of current (past 5 years) representative data Selected data for open water only Selected data that are representative and sufficient to make comparisons (=, <, >) Contacted primarily federal agencies that monitor open waters Obtained data for same media as objective (water, whole fish, edible fish)

10 Criteria for Selection of Data

Criteria for Selection of Data

Water Data usually available for each lake from one source Fish Selected adult top predator species preferentially Lake Trout (Lakes Superior, Michigan, Huron, Ontario) Walleye (Lake Erie) Selected skin-on-fillet data preferentially over dorsal plug data because generally more conservative in data sets examined

11 Primary Sources of Data

Primary Sources of Data

Water U.S. EPA GLNPO Environment Canada Whole Body Fish Tissue U.S. EPA GLNPO Canadian DFO State of Michigan Edible Fish Tissue U.S. EPA GLNPO Ontario Sport Fish Contaminant Monitoring Program State of Michigan

12 Results of Data Comparisons Water

Results of Data Comparisons Water

Pesticides < Objectives in all lakes (with few exceptions) Metals < Objectives in all lakes Not all parameters monitored in all lakes

13 Results of Data Comparisons Whole Fish

Results of Data Comparisons Whole Fish

DDT+ in Lake MI > 1.0 ug/g (ww) Mirex in Lake Ontario > DL PCBs in all lakes > 0.1 ug/g (ww) Mercury in all lakes < 0.5 ug/g (ww)

15 Comparison to Current Policy Values

Comparison to Current Policy Values

Definition of “policy value” - any criteria, standard guideline, or objective promulgated by agencies. Policy values reflect: Current knowledge base related to exposure and effects of contaminants in the environment Interest in protecting human, aquatic, fish and wildlife use of water, sediment and tissue Improvements in analytical methods since Annex 1

16 Policy Values for Water

Policy Values for Water

Unspecified Some Annex 1 Specific Objectives For the protection of aquatic life Some Annex 1 Specific Objectives Canadian Water Quality Guidelines Ontario Provincial Water Quality Objectives U.S. EPA Water Quality Guidance (GLI) and States For the protection of human health GLI and States For the protection of wildlife GLI and States

17 Comparison of Policy Values for Water

Comparison of Policy Values for Water

Many inconsistencies between Objectives and policy values Compared to policy values for protection of aquatic life, Objectives are often the lowest value GLI criteria for protection of human health and wildlife usually lowest values overall Some policy values for metals are hardness-dependent Policy values have been promulgated for many substances not listed in Annex 1

18 Policy Values for Whole Fish

Policy Values for Whole Fish

For the protection of wildlife consumers Annex 1 Specific Objectives DDT, Mirex, PCBs & mercury for protection of fish-consuming aquatic birds Canadian Tissue Residue Guidelines DDT, PCBs & Toxaphene for protection of wildlife consumers of aquatic biota Ontario Fish Tissue Residue Criteria DDT & mercury for protection of fish-consuming birds and in the case of mercury, aquatic life GLI and States Water criteria for protection of wildlife derived from fish tissue triggers for DDT, mercury, PCBs, 2,3,7,8-TCDD

19 Policy Values for Edible Fish Tissue

Policy Values for Edible Fish Tissue

For the protection of human health Annex 1 Specific Objectives for 5 pesticides Uniform Sport Fish Consumption Advisory Protocol PCBs State trigger values, action levels or consumption guidelines PCBs, pesticides, mercury, others FDA Action Levels PCBs, pesticides, mercury, others GLI criteria for the protection of human health based on fish tissue triggers PCBs, pesticides, mercury, others

20 Sediment Quality Policy Values

Sediment Quality Policy Values

Canadian Sediment Quality Guidelines Ontario Provincial Sediment Quality Guidelines U.S. EPA Draft Freshwater Sediment Quality Criteria New York State Sediment Criteria

21 Review of Annex 1 of the GLWQA
22 Procedures for Assessing Compliance

Procedures for Assessing Compliance

States and Ontario Primarily focused on nearshore areas, efforts directed at effects of fish & sediment contamination No systematic program to assess compliance in open waters Federal Agencies Environment Canada Reviews data and flags parameters for which the 90th % value > most sensitive policy values in US & Canada No formal reporting process U.S. EPA No systematic program currently in place

23 Issues to Resolve – Data Management

Issues to Resolve – Data Management

Method of averaging data that contain censored values Monitoring programs to use for compliance assessment Spatial and temporal reference of data to use for compliance assessment (potentially lake-specific) Definition of open water Time of year to sample Number of stations Variations in sampling and analytical protocols Analytical method for water Whole fish versus edible Species of fish and size

24 Issues to Resolve - Policy

Issues to Resolve - Policy

Use of both water and fish Objectives Internal consistency (i.e., BAF) Specification of fish “policy values” Whole fish versus edible (ecosystem health versus human health) Variation among agencies Discrepancies between Annex 1 Objectives and Parties listing of parameters of concern Parameters with “policy values”, but not listed in Annex 1 Parameters listed in Annex 1 that are not monitored

25 Policy Values for Parameters Not Listed in Annex 1

Policy Values for Parameters Not Listed in Annex 1

Additional parameters Canadian Water Quality Guidelines 44 additional organic substances or groups 5 metals 5 other inorganic substances or physical properties GLI and States 11 additional substances Tier II option (some states)

26 Issues to Resolve – Policy

Issues to Resolve – Policy

Conceptual basis for Objectives Not specified for all parameters Consistency with “policy values” Variation among agencies Consistency among Programs Annex 1 Objectives Lake-wide Management Plans (LaMPs) Indicators in SOLEC process Great Lakes Binational Toxics Strategy
