South Dublin County Council N7 Newlands Cross Upgrade Environmental Impact Statement Arup Consulting Engineers The recorded levels of PM10 are compared to the limit value of 50μg/m 3 daily average outlined in the 2002 Regulations. The results obtained at the site indicate that levels of PM10 are below this daily limit (refer to Table 9.7). Table 9.7 Results of PM10 Baseline Air Quality Monitoring Sample Date PM10 concentration (μg/m 3 ) 30/09/2007 27.6 01/10/2007 13.7 02/10/2007 22.3 03/10/2007 16.5 04/10/2007 20.4 05/10/2007 11.2 06/10/2007
South Dublin County Council N7 Newlands Cross Upgrade Environmental Impact Statement Arup Consulting Engineers 9.4.2 EPA Air Quality Monitoring The Environmental Protection Agency’s (EPA) “Air Quality in Ireland 2006” (2007) 11 describes the air quality zoning adopted in Ireland under the Air Quality Framework Directive (CEC, 1996) as follows: • Zone A (Dublin Conurbation); • Zone B (Cork Conurbation); • Zone C (16 Cities and Towns with population greater than 15,000); and • Zone D (Rural Ireland: areas not in Zones A, B and C). The location of the proposed scheme site falls under Zone A. Background levels from 2006 air quality monitoring of NO2, CO and PM10 provided by the EPA are presented in Table 9.8. Concentrations of each pollutant recorded in Zone A are averaged to represent typical background levels. The UK DEFRA Year Adjustment Calculator 12 was used to predict concentrations of each pollutant for the construction year (2009), opening year (2010) and for the design year (2025). None of these predicted concentrations exceeds the relevant AQS. Predicted pollutant background concentrations are included in Table 9.8 below. No Special Areas of Conservation (SACs) or National Heritage Areas (NHAs) are located within 200m of the proposed scheme which is the limit of influence recommended by the DMRB. Total oxides of nitrogen (NOx) was therefore excluded from the assessment as the AQS for NOx is for the protection of vegetation only. Table 9.8 Annual Mean Background Pollutant Concentrations for Zone A (EPA, 2007) Adjusted using UK DEFRA Year Adjustment Calculator ANNUAL ANNUAL ANNUAL ANNUAL ANNUAL YEAR AVERAGE NO2 AVERAGE PM10 AVERAGE PM2.5 AVERAGE CO AVERAGE BENZENE µG/M³ µG/M³ µG/M³ µG/M³ µG/M³ MEASURED 2006 27.8 17.8 10.7 500 2.7 PREDICTED 2009 25.25 16.6 9.96 401.57 2.44 PREDICTED 2010 24.47 16.3 9.78 380.31 2.39 PREDICTED 2025 22.23 16.32 9.79 359.06 2.42 LIMIT VALUE - 40 20/40 25 1 2,000 2 5 APPLICABLE - 2010 2010 2010 2005 2010 FROM 1 PM2.5 has a proposed concentration cap rather than a limit value (CEC, 2005). Measured and predicted values taken using 0.60 ratio of PM10 (EC, 2004). 2 AQS for annual mean CO is guideline from UK Highways Agency (2003) and UK DEFRA (2003). Directive 2000/69/EC Limit Value of 10,000μg/m 3 is for 8-hour mean CO. EPA background levels are used for the purpose of this assessment as they represent continuous monitoring over a one-year period whereas the baseline air quality monitoring only represents continuous monitoring over a 1-month period. This is in compliance with the 2002 Regulations which specify a minimum data capture of 90% for continuous monitoring of NO2, SO2 and particulates. Toluene, ethylbenzene, and xylene are excluded from the assessment owing to the low levels detected relative to the Danish C-Values. December 2007 Page 148
