Environmental Approach

• Risk Assessment vs. Generic Remediation– Accelerated Schedule– Cost Effectiveness– Treatment Options Ruled Out Early– Sustainability– Certainty

21

Obstacles Identified

• Accelerated Schedule• Volume of Work• Implications of Amendments to O.Reg.

153/04• City of Toronto Review Process• MOE Review Periods and Resubmission

of Risk Assessments

22

Mitigation Strategies

• Expand the Team by Drawing on the Resources Available Within CH2M Hill

• Engage the MOE and City Early• Integrate the Review Process with the

Drafting Process• Complete Activities Concurrently

23

Mitigation Strategy Response

• CH2M Hill

• City of Toronto

• Ministry of Environment

24

Phase I ESA

• Four Phase I ESA’s Completed for the West Don Lands

• Three Cover the PAAV

25

Phase II ESA

• Nine Phase II ESAs for the West Don Lands

• Five Cover the PAAV

26

Site Characterization

• Over 1000 Historical BH/MW/TP/Exc.

• Over 500 Additional Completed

– 1400+ Soil Samples– 185 MW’s & 317 GW

Samples

27

Site Characterization

28

Site Characterization

• Nature and Extent of Impacts – Soil

• Impacts sporadically distributed across Site • Typically limited to shallow soil

(fill and upper native soil)• Categories of chemicals found above MOE

Generic Standards: Metals/inorganics, VOCs, PHCs, PAHs, PCBs, Phenols, and Dioxins/Furans

29

Site Characterization

• Nature and Extent of Impacts – Groundwater

• Impacts sporadically distributed• No evidence of plumes identified• Categories of chemicals found above MOE

Generic Standards: Metals/inorganics, VOCs, PHCs, PAHs, and PCBs

30

Risk Assessment

• Subdivision of The West Don Lands into Logical, Manageable Groupings– Nine RA

Groups, Five Cover PAAV

31

Risk Assessment

• Primary Exposure Pathways– Dermal Contact

• Soil and Groundwater– Inhalation

• Vapour Intrusion• Managing Risk of Exposure

– PSS Remediation– Risk Management Measures

32

Risk Assessment

• Identify Contaminants of Concern• Develop Conceptual Site Model• Evaluate Exposure Scenarios• Create Property Specific Standards• Identify Necessary RMM’s to Support

Redevelopment• Remove Soils Exceeding PSS• Implement RMM’s During Construction

33

PSS Remediation Areas

• Limited PSS Remediation Necessary to Support RSC Filing

34

Slab on Grade Construction RMM

35

Basement Construction RMM

36

Road Construction RMM

37

Service &Utility Fill Zone RMM

38

Hard Cap Barrier RMM

39

Soft Cap Barrier RMM

40

Environmental Requirements

• Actions for Future Developers– Manage Soil, GW, Sediment– Design & Install Necessary RMM’s– Implement O&M Requirements of RMM’s– Implement GW Monitoring

41

Where Are We Now?

• Risk Assessments Accepted by the MOE

• Remaining Approvals are On-going

42

Where Are We Now?

• Procurement of PSS Remediation Contractor Underway

• Reviewing Certificates of Property Use for Posting to the EBR

• Finalizing Phase II ESA’s• Preparing to File RSC’s• Looking at the Next Areas of the WDL to

Investigate43

Impacts of Pan Am Athletes’ Village

• Original Schedule for the Build Out of the West Don Lands – 15-20 Years

• Pan Am Athletes’ Village Comprises Almost Half of the WDL – Complete for 2015

• Public Initiative to Spur Private Investment
