An engineering report has found gaps and deficiencies in the draft Renewable Energy Approval (REA) documents to construct a wind farm in Dutton Dunwich.
The municipality retained Morrison Hershfield Limited to evaluate the Strong Breeze Wind Project draft report prepared by Stantec Consulting Ltd. for Invenergy.
The findings were released during a regular council meeting on Wednesday.
In the Morrison Hershfield report, the company found information lacking in the draft REA submission from environmental and engineering perspectives.
Inconsistencies with respect to the rated capacity of the two types of turbine models under consideration are also documented in the report prepared for the municipality.
In other areas, the study found information lacking on underground electrical line routes, potential impacts to municipal infrastructure, height of aerial electrical lines and the anticipated span between support posts.
The report is also critical of how setback and property line measurements for the proposed turbine locations were derived.
The Morrison Hershfield report found: “The assessment appears to have been undertaken as a desktop exercise only.”
In the wind farm proponent’s decommissioning plan documents, the municipal study determined the intent is to return the land to pre-existing condition or better, yet turbine and transformer foundations will only be removed to a depth of approximately one metre and re-vegetated.
According to the review done for the municipality, the REA submission also lacks sufficient archaeological, cultural and natural heritage assessments.
No detailed review was found in the documents for potential impacts the project may have on potable water sources.
Council will include the findings in its municipal consultation form as part of the 90-day municipal review process, as set out in provincial regulations for wind farm proposals.
Over 80 per cent of Dutton Dunwich property owners have voted against wind farms within their community.
Invenergy wants to construct up to 20 wind turbines in Dutton Dunwich.
