• Air Quality indicators:

– Combustion by-products

– Fugitive dust

– CO, NO2, SO2, SPM, PM10, PM2.5

• Noise Levels indicator:

– Energy equivalent noise level (Leq)

• Measures are:

– Changes to indicators

– Concentrations or levels of indicators

12

In-design Mitigation

• Assessment of effects based upon the

project being proposed

• Proposed project includes in-design

features that avoid effects

– Fans and vehicles maintained in good

working order

– Onsite construction vehicles and equipment

meet Tier 2 standards

15

Page 22: E-doc 3541930 - Canadian Environmental Assessment … · E-doc 3541930 E-doc 3541930 . NWMO Meeting with CNSC Staff – Technical Support ... Duck Kim, Rob Dobos, Sandros Leonardelli,

Potential Effects – Air Quality

• Adverse effects predicted for all indicators,

with the exception of SO2

• Site preparation and construction phase:

– exceed criteria for 1-hour NO2, 24-hour SPM, 24-

hour PM10 and 24-hour PM2.5 at fenceline

– occur less than 1% of the time

• Operations phase:

– concentrations are within relevant criteria

• Decommissioning similar to, or less than,

site preparation and construction phase

16

Page 23: E-doc 3541930 - Canadian Environmental Assessment … · E-doc 3541930 E-doc 3541930 . NWMO Meeting with CNSC Staff – Technical Support ... Duck Kim, Rob Dobos, Sandros Leonardelli,

Significance of Effects – Air Quality

• Site preparation and construction phase:

– High magnitude, local geographic extent, low

frequency, low duration, reversible

– “May not be significant”

– Consider monitoring to confirm significant

effects do not occur

• Operations phase:

– Magnitude for all indicators is low

– Not significant

17

Page 24: E-doc 3541930 - Canadian Environmental Assessment … · E-doc 3541930 E-doc 3541930 . NWMO Meeting with CNSC Staff – Technical Support ... Duck Kim, Rob Dobos, Sandros Leonardelli,

Potential Effects – Noise Levels

• Changes in noise levels predicted at all

receptor locations

• Adverse effects predicted at one receptor:

– Increase of 5 dBA at the Baie du Doré during

site preparation and construction phase, and

decommissioning phase

– Increases at other receptors ≤3 dBA (changes

would not be perceptible)

Considerations for Follow-up Monitoring

• Monitoring incorporated into project

– Consistent with current WWMF monitoring

– Air quality monitoring in ventilation system

• Continuous sampling

• Monitoring the duct system for methane, CO, NOX

• Air monitoring of construction emissions to

confirm significant effects do not occur

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

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
