Air Quality and Climate Factors Introduction This chapter assesses the air quality and climate impact associated with the Proposed Project. Details of the Proposed Project are outlined in Chapter 4. Assessment Methodology The impacts have been assessed in terms of Air Quality and Climate of the local environment as defined in the in the EPA “Advice Notes on Current Practice Preparation of (EPA, 2003). The assessment methodology is based on EIS” guidance outlined in the Environmental Protection Agency (EPA) Guidance “Air Dispersion Modelling From Industrial Installations Guidance (EPA, 2010), Note” Transportation Infrastructure Ireland (TII (formerly the National Roads Authority) Guidance The Treatment Of Air Quality During The Planning “Guidelines For And Construction Of National Road and UK DEFRA Schemes” (TII, 2011) Guidance of the Environment Act 1995: Local Air Quality Management, “Part IV air emissions in the study LAQM.TG(16)” (UK DEFRA, 2016). Vehicle-derived area have been modelled using the ADMS-Roads dispersion model (Version 4) which has been developed by the Cambridge Environmental Research Consultants (CERC) and following guidance issued by the EPA (EPA, 2010). The model is a steady-state Gaussian plume model used to assess pollutant concentrations associated with road sources and is based on the ADMS model also developed by CERC. The air dispersion modelling input data consisted of information on the physical environment (source geometry and building dimensions), detailed emission factor formulations and appropriate hourly meteorological data. Using this input data, the model predicted ambient ground level concentrations for each hour of the
