Air Quality Impact Assessments for Planning Applications and EIA

Contact: airquality@arcusconsulting.co.uk

Air quality assessments may be required when there are potential impacts on local air quality from the following:

  • Dust emissions during demolition and or construction
  • Emissions from plant and HGV movements during demolition and or construction
  • Emissions from increased traffic due to the operation of a proposed development
  • Emissions from de-centralised energy provision (e.g. CHP or biomass) or industrial plant, due to the operation of a proposed development
  • Emissions of dust and or odour due to the operation of a proposed development

An air quality assessment may also be required where new receptors, such as residential properties, will be introduced into an area of poor air quality, for example areas affected by dust and or odour.

Our Air Quality team provides air quality impact assessment services across a wide range of sectors, including residential, industrial, power, water/waste water, etc.  We provide air quality assessments as Environmental Statement chapters as part of the Environmental Impact Assessment process or as supporting documents for planning applications.

Our Air Quality team conducts air quality impact assessments, odour impact assessments, air quality neutral assessments and climate change impact assessments.

Air quality assessments focus on the following typical sources of pollution and receptors:

Sources of Pollution

  • Background concentrations of pollutants
  • Existing road traffic emissions
  • Existing industrial emissions
  • New/increased road traffic emissions
  • New/increased industrial emissions
  • Plant and machinery emission

Receptors

  • Existing residents
  • New residential properties
  • Other public areas – schools, hospitals
  • Workplace environments
  • Ecological receptors – sensitive habitats
  • Air Quality Management Areas (AQMA)

We can undertake the following types of air quality modelling, tailored to each specific project:

  • DMRB Screening Assessments – a simple model for traffic emissions, usually sufficient provided air quality objectives are not exceeded which would trigger the need for more detailed dispersion modelling
  • Air Dispersion Modelling – for modelling traffic emissions where exceedances of air quality objectives are expected, or for some developments with high traffic generation located in an Air Quality Management Area (AQMA). Modelling is also used for assessing dispersion of pollutant emissions from point sources (e.g. on site combustion or offsite industrial sources)
  • Odour Modelling – for assessing the odour levels at receptor locations based on emissions of odour generally (expressed as odour concentration) or of specific chemicals, such as hydrogen sulphide (H2S). Typically this is undertaken for receptors close to waste water treatment processes or food production processes.

We undertake robust and proportionate air quality assessments.  Where possible, we seek to use the DMRB screening assessment to demonstrate that air quality (in particular NO2 and PM10) complies with air quality objectives so as to avoid the need for detailed modelling.

We undertake air quality assessment work in the following sectors:

  • Residential
  • Commercial
  • Industrial
  • Other sectors where on-site combustion is used, such as CHP plant or gas/biomass boilers
