APS can provide air quality expert witness services for both developers, objectors and local authorities. With access to over 50 years of experience, including expert witness support, we are well suited to help.

Our expert witness services include:

• Liaising with the local authority and Counsel to discuss the best approach
• Detailed pollutant monitoring analysis
• Undertaking bespoke air quality assessments
• Providing proof of evidences
• Being an expert witness
• Providing ad-hoc support throughout the process

APS can provide litigation services for any legal issue related to air emissions, dust or odour nuisance or exposure to poor air quality. With access to over 50 years of experience, including litigation support, we are well suited to help.

We can support you throughout your legal proceedings and ensure you are provided with accurate and robust evidence. APS has access to a network of highly qualified experts who have vast litigation experience to provide the best support where needed.

APS can help both local authorities and institutions develop air quality policies. As members of both the Institution of Environmental Sciences (IES) and the Institution of Air Quality Management (IAQM) we have expert knowledge and understanding of the current air quality best practice and guidance.

We also form part of the IAQM committee panel and thus have inside knowledge of any upcoming national policies. With access to over 50 years of experience, APS can provide both technical and written-based input for policies.

APS can provide input into both local and government air quality guidance. As members of both the Institution of Environmental Sciences (IES) and the Institution of Air Quality Management (IAQM) we have expert knowledge and understanding of the current air quality best practice and guidance.

We also form part of the IAQM committee panel and thus have inside knowledge of any relevant upcoming guidance. APS's Directors also have experience at national level and have recently assisted with Environment Agency and Greater London Authority guidance.

With access to over 50 years of experience, APS can provide both technical and written-based input for guidance development.

Report Reviewing

As expert air quality professionals, APS can review air quality, dust and odour assessment reports for planning applications on behalf of local authorities. APS staff have vast experience in a range of industries, including reviewing air quality assessments of power-generating facilities on behalf of local authorities.

Quality Assurance

APS can support local authorities with quality assurance services to ensure any modelling carried out by the local authority, or by a third party, is accurate and robust.  APS staff have vast experience in quality assurance and have carried out quality assurance of both small and large studies, including a Clean Air Zone assessment.

Report Proofing

APS can also proof read air quality, dust and odour assessment reports on behalf of other companies to ensure planning and permit application are accurate, robust and given the best chance of success.  With access to air quality professionals with over 40 years of experience, APS’s proof-reading service can support developments of any size.

Air quality modelling in the UK is usually carried out using gaussian dispersion models, such as the ADMS model, for which APS staff have used extensively.

For more bespoke scenarios, Computational Fluid Dynamics (CFD) modelling can be used to overcome some of the limitations of gaussian models to provide more realistic modelling.

APS staff have experience in modelling with both gaussian dispersion models and CFD models, and have given talks on both at conferences.  We are thus well placed to assist with any type of modelling.

For major developments an Environmental Impact Assessment (EIA) may be required for a planning application.  This includes an Environmental Statement (ES) that may include air quality and odour chapters. APS staff have extensive experience of undertaking EIA air quality and odour assessments and are therefore well placed to help.

Recent changes to EIAs require climate change chapters to be included. APS staff have spent years pioneering global monitoring of greenhouse gases, such as carbon dioxide, methane and aerosols, and have published numerous scientific papers and given many international conference presentations relating to global warming and climate change. APS are therefore well suited to assess climate change for any type or size of development.

APS can provide EIA support for any type of development, see our planning application services.
