Air Quality & Ecology

The effects of poor air quality on human health are often the foremost concern when it comes to new Developments, however when a project is situated in or near sensitive ecological sites, extra care must be taken to ensure the adequate protection of natural features, habitats and species.

Potential ecological receptors are often designated sites, ranging in size and prominence from local nature reserves and SSSI’s up to RAMSAR sites and SAC’s. While the makeup and sensitivity of these sites may vary, the primary concern from an air quality perspective is the deposition of Nitrogen and Sulphur. Natural systems are often in a delicate state of balance and the introduction of these compounds in unsustainable levels can lead to considerable damage to habitats and ecosystems.

All new Developments must therefore consider the potential for Nitrogen and Sulphur releases either directly, in the case of agricultural buildings, combustion plant and waste-water Developments, or via the new traffic flows they generate, in the case of property Developments. If the Development is situated in, or has a considerable influence on roads that run through, designated sensitive sites, then dispersion modelling of emissions is likely to be required to ensure that critical loads for each pollutant are not exceeded.

Here at Vale we have considerable experience in modelling emissions from roads, buildings and point sources to determine the potential effects on sensitive ecological receptors. We also have a long track record of working alongside ecological colleagues in determining potential impacts and effectively working through the overlap in disciplines.
