Introduction
• The Socio-economic TSD uses “Community Well-being” as an analytical framework
“a state of Financial, Human, Social and Natural Assets possessed or desired by a community which enables its residents, organizations and institutions to support each other in performing all the functions of life and in developing their maximum potential”
• Framework includes 5 “Community Assets” and Public Attitudes toward Personal and Community Well-being

• Human Assets
– Population and mobility has been relatively stable
since 1996
– Broad range of healthcare, social, safety and
emergency services are available to residents
– Meeting healthcare requirements has emerged as the
major community issue
– School boards report capacity to accommodate future
growth
Existing Environment
84
• Financial Assets– Modest employment and income
growth since 1996
– Study area is largely dependent on agriculture and its largest employer, Bruce Power, for its Business Activity
– Tourism is very important to local and regional economies
– Residential property values increased by 95% since 2001
• Slight downturn in property values in 2009, consistent with Ontario trend
– Municipal Finances of Kincardine based on ~1.3 Billion dollars of taxable assessments
Existing Environment (cont.)
Lake Huron, local parks, beaches,
trails and attractions contribute to the
tourism industry
85
• Physical Assets– Study areas are characterized by mix of rural and small
settlement areas
– Lake Huron and its shoreline are the defining features of the area
– The Bruce Nuclear site has an organized, spatial and industrial nature. Inland is primarily agricultural with the exception of nearly 115 large wind turbines adding an industrial character.
– Housing stock has grown between 2001-2006
– Municipalities have sufficient water and sewage capacity to meet current and future demands
– Current traffic levels of service around the Bruce Nuclear site are not adequate
Existing Environment (cont.)
86
• Social Assets– LSA and RSA composed of
vibrant and cohesive communities
– Wide range of community facilities and recreational programs are available to residents
– Visitation to InverhuronProvincial Park increasing
• Plans exist to expand services at Inverhuron
– Boating, hiking, nature viewing and swimming are popular outdoor activities
Existing Environment (cont.)
Kincardine’s Scottish Festival
and Highland Games
87
• Public Attitudes toward Personal and Community Well-being are at the core of the Community Well-being Framework– Residents provided high ratings of feelings of personal health,
safety, overall community satisfaction and commitment to community
– Residents consider themselves as having a healthy balance of community assets that contribute to their well-being
Existing Environment (cont.)
88
How Effects Were Predicted
• Economic Modelling– Direct, indirect and induced impacts on Financial
Assets
– Impacts on Human and Physical Assets
• Surveys and Interviews– Same methods (and respondents) as used in
Baseline data collection to understand potential impacts and concerns related to DGR
• Analyses of interaction with other relevant Natural Assets documentation and studies and their effects
• Case Studies and Past Experience
89
Example of Methods Used and Effects Prediction
• Would DGR change visitation at Inverhuron Provincial Park?
– 51 Tourists and Day Users surveyed at Inverhuron Provincial Park
– 38 respondents replied “no”
– Of the 13 that replied “yes”• 6 stated that they may not come back
• 5 stated that they would more closely monitor safety at the park
• 2 stated they would still come to the park but that it may affect other aspects of visitation

Summary of Effects
• The DGR Project is anticipated to have an overall positive effect on Community Well-being, enhancing Human, Physical and Financial Assets
• Mitigation measures for effects on Natural Assets are sufficient to avoid effects on other Community Assets
• Existing Community Agreement contributes to beneficial effects
• OPG/NWMO consultation and communication programs will continue to evolve to address DGR-specific issues and concerns

Aboriginal Traditional Knowledge
• Held by, and unique to, Aboriginal peoples
• Built up by a group of people through
generations of living in close contact with
nature
• Cumulative, dynamic and builds upon the
historic experiences of a people and
adapts to social, economic, environmental,
spiritual and political change.
Aboriginal Communities
• Traditional territories of the Saugeen Ojibway Nations
(SON) and the settlement areas and traditional
harvesting territory associated with Métis peoples who
historically settled in relation to the Saugeen River.
– The Saugeen Ojibway Nation traditional territory incorporating both
the Chippewas of Nawash Unceded First Nation – Cape Croker
Reserve No. 27 and the Chippewas of Saugeen First Nation-
Reserve No. 29
– Métis Nation of Ontario members of the Owen Sound - Saugeen
Shores Métis Council who historically settled in relation to the
Hudson Bay’s Bay Company post at the mouth of the Saugeen
River
– Members of the Historic Saugeen Métis Council who historically
settled in relation to the Hudson Bay’s Bay Company post at the
mouth of the Saugeen River
Aboriginal Communities
• The Saugeen Ojibway Nation
– Chippewas of Nawash Unceded First Nation – Cape
Croker Reserve No. 27
– Chippewas of Saugeen First Nation- Reserve No. 29
• Owen Sound - Saugeen Shores Métis Council
• Members of the Historic Saugeen Métis Council
Regional Study Area
Sources of Aboriginal Knowledge
• Review of literature with respect to Saugeen Ojibway Nation, Ojibway way of life, culture and beliefs, and Métis way of life, culture and beliefs
• Traditional knowledge, and opinions expressed publicly or to OPG/NWMO by Aboriginal people through a review of media and communication records
• Examination of previous EAs
• Expertise of the technical specialists who based their criteria on factors that are traditionally and current important to Aboriginal people and their communities
Issues of Importance
• Crown’s fiduciary “duty to consult and accommodate”;
• First Nations burial grounds on the Bruce nuclear site;
• cultural heritage and traditional knowledge;
• spiritual considerations;
• land claims, traditional territory and long-term use of lands and waters;
• fishing and harvesting rights;
• health of members of Aboriginal communities;
• environmental health;
• economic benefits and/or impacts (includes alternative energy, scholarships, employment, procurement, tourism);
• possibility of high-level waste being transported to site; and
• legacy issues related to the installation of the original facility.
Aboriginal Interests VECs
VEC Rationale for Selection Indicators Measures
Aboriginal
Communities
• The DGR Project may affect the economic base,
levels of service, social structure, and/or community
stability of Aboriginal communities and residents
• Aboriginal populations
• Local employment
• Local business activity
• Community character
• Change in populations
• Change in employment levels
• Change in business activity
• Change in community characteristics
Aboriginal
Heritage
Resources
• Aboriginal heritage resources such as
archaeological sites may be affected by the
excavation of previously undisturbed lands or deeply
buried artifacts
• Specific cultural or spiritual sites may be affected as
they are places that have historical, religious or
cultural significance to Aboriginal people
• Presence of known archaeological
sites/artifacts
• Potential of presence of unknown
archaeological sites/artifacts
• Identification of archaeological
sites/artifacts within Local Study
Area
• Identification of cultural or spiritual
sites within Local Study Area
Traditional
Use of Land
and
Resources
• Aboriginal people have traditionally made use of
lands and resources. The DGR Project may affect
wildlife, fish, waterfowl, their habitats and sensitive
plants that Aboriginal persons fish, hunt trap, or
gather for food, cultural, or economic purposes
• Changes in the natural environment, as a result of
the DGR, may indirectly impact the other Aboriginal
interests VECs
• Atmospheric Environment
• Hydrology and Surface Water Quality
• Aquatic Environment
• Terrestrial Environment
• Geology
• Radiation and Radioactivity
• Measurable change in natural
environments
Aboriginal
Rights and
Non-physical
Cultural
Interests
• Aboriginal people possess inherent and distinct land
and cultural rights that require protection. Aboriginal
people may consider the DGR Project as potentially
limiting or impinging on these inherent rights
• Limitation or impingements on inherent
rights
• DGR effects on native heritage
resources
• DGR effects on traditional use of lands
and resources by Aboriginal people.
• DGR effects on specific non-physical
cultural and spiritual interests
• Documented evidence of Aboriginal
rights within Local Study Area
• Identification of aboriginal people
within the Local Study Area
• Identification of traditional use of
lands and resources by Aboriginal
people within the Local Study Area
• Identification of specific non-physical
cultural and spiritual interests by
Aboriginal people within the Local
Study Area
Existing Environment
• Aboriginal Communities– Reserves well removed from Site Study Area
– Local economy including tourism mirrors that of the non-native communities
• Aboriginal Heritage Resources– Chiibegmegoong (Spirit Place) sacred site to SON
• Traditional Use of Lands and Resources– SON manage commercial fishery
– Lake whitefish is the largest component
• Aboriginal rights and Non-physical Cultural Interests– Fishing and harvesting rights
– Aboriginal title
– Traditional Ojibway spiritual worldview that physical world, including rock of the earth, is the first order of creation
How Effects Were Predicted
• Analyses of interaction with other relevant Natural Assets and
their effects
• Analyses of interaction with other relevant Socio-Economic
Assets and their effects
• Examination of previous EAs
• Review of literature, traditional knowledge, and opinions
expressed publicly or to OPG/NWMO by Aboriginal people
through a review of communication records
• Expertise of the technical specialists who based their criteria
on factors that are traditionally and current important to
Aboriginal people and their communities
Potential Interactions with VECs
Direct Interactions
• Potential to uncover and disturb archaeological artifacts
• Potential to impinge upon asserted Aboriginal rights and interests, resulting in disturbance to spiritual interests
Indirect Interactions
• Potential to interact with Aboriginal Communities due to nuisance air quality and noise effects, affected water supply, groundwater quality and flow
• Potential to changes in populations of wildlife, fish, waterfowl and their habitats
Measurable Change on VECs
Direct Interactions
• Potential benefit from worker, payroll and purchasing activity for Aboriginal Communities
• Site preparation and excavation activities may uncover and disturb unknown archaeological sites or artifacts
• DGR Project may not be compatible with traditional Ojibway spiritual interests related to the rock of the earth
Indirect Interactions
• Potential Air Quality and Noise Levels effects
Residual Adverse Effects on VECs
Aboriginal Communities
• No adverse effects from air quality and noise effects due to in-design mitigation measures on Aboriginal Communities
Aboriginal Heritage Resources
• Culturally-sensitive area B is located in extreme SE corner of DGR Project Area and development should be avoiding in this unaltered landscape
Traditional Use of Lands and Resources
• Area affected by terrestrial and aquatic represent a small fraction of FN traditional territory or Métis harvesting territory and traditional hunting does not occur within Bruce nuclear site boundary
Aboriginal rights and Non-physical Cultural Interests
• SON and OPG/NWMO Protocol Agreement
• Agreements with Métis communities
