MOECC admission of ‘tonality’ a step forward but more action needed
(C) Wind Concerns Ontario
Residents living near the K2 wind power project in the Township of Ashfield-Colborne-Wawanosh have received a report from the Ontario Ministry of the Environment and Climate Change following noise testing done at their property, Wind Concerns Ontario has learned.
WCO received a copy of the MOECC report and other correspondence from the residents, who are members of the coalition of Ontario community groups and individuals in Ontario concerned about the impact of wind turbines on the economy, natural environment, and human health.
The noise testing was done at their request, connected to complaints made to the MOECC about excessive noise and sound pressure or vibration being emitted from industrial-scale wind turbines at the K2 power project.
The MOECC report’s Executive Summary states that
Based on the results of the analysis, it is acknowledged that sound from the wind turbines was audible during the measuring campaign at levels that appear to exceed the applicable sound level limits, and based on C3 measurements conducted at a nearby receptor (the distance is about 1250 m from R876; where the same turbine(s) within 1500 m distance impact both receptors) it was further concluded that there is a possibility that sound from the nearby turbines could be tonal. To confirm compliance, it is recommended that a tonal audibility assessment and detailed noise audit be undertaken in accordance with Part D of the draft Compliance Protocol for Wind Turbines Noise, NPC 350, 2017.
This is remarkable as it is the first time MOECC supervisory staff have admitted to “tonality” in wind turbine noise emissions. And also because, in previous noise testing by the MOECC, the Ministry claimed results were “inconclusive” due to other noises such as birds chirping and tree leaf movement.
A tonal audibility assessment is a step forward.
Is it enough?
The Ministry needs to acknowledge that there is a problem with wind turbine noise emissions, and in the case of this particular report and recommendation, immediate action is required, including comprehensive testing including for infrasound which was excluded by the equipment used for these tests.
It is time for government to accept responsibility for its wind power program and the impacts on people who were given no choice but to live with them.
