Mr. Eric Erhard is a retired professional engineer who lives near a proposed wind farm in southern Ontario. He attempted to gain accreditation as an expert witness related to application of ISO standards on noise modeling to wind turbine noise specifically. He based his experience with the relevant ISO standard in his professional career for the Chatham-Kent Wind Action Inc. v. Director, Ministry of the Environment tribunal.
The Tribunal was not convinced and stated:
In reviewing Mr. Erhard’s submissions, the Tribunal finds that he does not have the specialized education, training or experience to qualify him to give expert evidence with respect to the application of ISO 9613-2 to noise from wind turbines. Mr. Erhard did not specifically submit that he had any specialized education or training with respect to the application of ISO 9613-2 to noise from wind turbines. Instead, he relied on his experience working for a company as an engineer and working with ISO 9613-2.
For the purpose of giving expert opinion evidence, the Tribunal finds that Mr. Erhard has failed to establish that the ISO standard can be applied to evaluate a project as complex as an industrial wind turbine facility by someone who does not have specialized knowledge and experience for this type of application.
The Tribunal agreed that he could speak to the ISO standard, but as he had no expertise on its application to wind farms and presented no evidence that his concerns related to application of the standard would have any impact on health, it was irrelevant testimony.
