Newport City Council Newport City Council 2017 Air Quality Progress Report In fulfillment of Part IV of the Environment Act 1995 Local Air Quality Management September 2017 LAQM Progress Report 2017 i Newport City Council Local Authority Peter Mackintosh Officer Senior Scientific Officer Department Environmental Health Law & Regulation Room 719 Civic Centre Address Godfrey Road Newport NP20 4UR Telephone 01633 210850 E-mail [email protected] Report Reference Final V1_1 number Date September 2017 LAQM Progress Report 2017 ii Newport City Council Executive Summary This report covers the 2016 monitoring period. Air quality in Newport has shown little sign of improvement compared to the previous (2015) round of monitoring. Twenty five new diffusion tube locations have been added during 2016. Twelve of the existing fifty five tubes have been relocated making a total of eighty monitoring locations, and two automatic stations. Of these new locations several new exceedances have been encountered which include: Caerphilly Road, Cefn Road and George Street for which new AQMAs should be considered. Monitoring sites along the M4 corridor appear to have been impacted by the Brynglas Tunnel works. A marked improvement in air quality along some sections of the M4 may be attributed to the night closures, reducing the overall volume of road traffic emissions. During 2016 work has continued on drafting a revised air quality action plan which will be ready for public consultation in due course. The results of this report recommend the following actions: 1. Declare New AQMAs for: a. Cefn Road b. Caerphilly Road c. George Street Revise AQMA boundaries for: d. Caerleon e. Chepstow Road f. Malpas Road 2. Public consultation on a draft air quality action plan. 3. Continue the review and development of the air quality monitoring programme.

The city population of Newport is just over 140,000 (based on the national census) covering approximately 84 square miles. A large proportion of the authority is urban which includes a large docks area, several large industrial estates and the M4 motorway. There has been a steady decline in heavy industry over the past three decades resulting in the gradual replacement of industrial installations with residential dwellings. Recently the city centre has undergone extensive regeneration including a new shopping facility, parking and public transport infrastructure. The M4 motorway transects several of Newport’s residential suburbs and there are proposals to redirected M4 around the south of the city to ease congestion. 1.2 Purpose of Progress Report This report fulfils the requirements of the Local Air Quality Management (LAQM) process as set out in Part IV of the Environment Act (1995), the Air Quality Strategy for England, Scotland, Wales and Northern Ireland 2007 and the relevant Policy and Technical Guidance documents. The LAQM process places an obligation on all local authorities to regularly review and assess air quality in their areas, and to determine whether or not the air quality objectives are likely to be achieved. Where exceedences are considered likely, the local authority must then declare an Air Quality Management Area (AQMA) and prepare an Air Quality Action Plan (AQAP) setting out the measures it intends to put in place in pursuit of the objectives. 1.3 Air Quality Objectives The air quality objectives applicable to LAQM in Wales are set out in the Air Quality (Wales) Regulations 2000, No. 1940 (Wales 138), Air Quality (Amendment) (Wales) Regulations 2002, No 3182 (Wales 298), and are shown in Table 1.1. This table shows the objectives in units of micrograms per cubic metre µg/m3 (milligrams per LAQM Progress Report 2017 1 Newport City Council cubic metre, mg/m3 for carbon monoxide) with the number of exceedences in each year that are permitted (where applicable).
