AONA Environmental has completed Air Quality, Odour and Noise Impact Assessments for a wide range of renewable energy developments including wind farms, solar farms and anaerobic digestion biogas plants.
Air Quality, Odour and Noise Impact Assessments of renewable energy projects follow a similar approach irrespective of the project type;
- An assessment of baseline conditions at the nearest existing sensitive receiver locations.
- A prediction of the Air Quality, Odour and Noise Impact from the proposed renewable energy source. This is prepared using prediction models with manufacturers data of future air pollutant, odour and noise emissions or reference to data from existing similar projects.
- An assessment of impacts at the nearest existing sensitive receivers locations versus applicable legislative limits and guidance.
- A recommendation of appropriate mitigation measures in accordance with best available techniques.
For example, for a detailed assessment of wind turbine noise impacts, AONA Environmental undertake assessments using CadnaA noise modelling software in accordance with the Institute of Acoustics ‘A Good Practise Guide to the Application of ETSU-R-97 for the Assessment and Rating of Wind Turbine Noise’.
For a detailed assessment of odour impacts from a biogas plant, AONA Environmental undertake assessments using odour dispersion modelling, with the results compared with the relevant odour benchmark level (ou/m3) and the significance assessed against the appropriate guidance outlined by the regulatory authorities.
