EXECUTIVE SUMMARY This report contains the results of the 2006 Updating and Screening Assessment for local air quality within Renfrewshire. It has been produced on behalf of Renfrewshire Council which has an obligation to assess air quality under Part IV of the Environment Act 1995. The Local Air Quality Management Technical Guidance TG.(03) has been followed in order to conduct this assessment. The assessment discusses seven main air pollutants, namely carbon monoxide, benzene, 1,3- butadiene, lead, nitrogen dioxide, sulphur dioxide and particulates. It has been concluded that it is unlikely that air quality objectives for carbon monoxide, benzene, 1,3-butadiene, lead and sulphur dioxide will be exceeded within Renfrewshire. There is, however, evidence of air quality objectives for nitrogen dioxide being exceeded at two locations and air quality objectives for particulates being exceeded at three locations. Further assessment of these locations is therefore recommended.

The assessment was conducted using data gathered in 2005. The assessment is required under the Local Air Quality Management (LAQM) framework and it follows the guidance set out in the Local Air Quality Management Technical Guidance LAQM.TG(03)1, hereafter referred to as the ‘technical guidance’. The assessment and the report have been completed in collaboration with personnel from Renfrewshire Council and the Scottish Environment Protection Agency (SEPA). It includes updated information on industrial, transportation and domestic emission sources as well as monitoring data in order to identify any changes to local air quality. 2 BACKGROUND 2.1 Local Air Quality Management framework The LAQM framework is designed to help local authorities review and assess current and future air quality in their area. The LAQM framework was introduced under the Environment Act 1995 and it requires local authorities to assess concentrations of seven air pollutants compliance against their standards and objectives set out in the Air Quality Strategy for England, Scotland, Wales and Northern Ireland2. For local authorities within Scotland further regulations are set out in the Air Quality (Scotland) Regulations 2000 and Air Quality (Scotland) Amendment Regulations 2002. The pollutants contained within these regulations and their relevant objectives are presented in Table 1. 1 Part IV of the Environment Act 1995, Local Air Quality Management Technical Guidance, LAQM.TG(03), Defra et al (2003). 2 The Air Quality Strategy for England, Scotland, Wales and Northern Ireland: Working together for clean air.
