Introduction This Chapter presents the findings of the assessment of the likely significant effects of the Proposed Development with respect to air quality. The purpose of this Chapter is to describe and evaluate the likely air quality impacts of the Proposed Development considering relevant national, regional and local guidance and regulations as well as relevant European Union (EU) guidance and directives. This Chapter has been prepared by Peter Brett Associates LLP (PBA). In accordance with the Infrastructure Planning (Environmental Impact Assessment) Regulations 2017 (as amended) (the Infrastructure EIA Regulations 2017), a statement outlining the relevant expertise and qualifications of competent experts appointed to prepare this Environmental Statement is provided in Appendix A.2. REP will have potential implications for local air quality principally from the flue gases emitted through the combustion processes from the Energy Recovery Facility (ERF) and Anaerobic Digestion facility. Furthermore, there will be emissions associated with the construction and demolition phases of the Proposed Development and the transport of materials to and from the REP site by river and road during both construction and operational phases. 7.2 Legislation, Policy, Guidance and Standards Legislation Ambient air quality is regulated through European Directives that set limit values on the concentrations of key pollutants. The most recent of these is the Air Quality Directive 2008/50/EC on cleaner air for Europe. This sets air quality limit values, target values and critical levels for a number of air pollutants established by the European Council for the Protection of Human Health, Vegetation and Ecosystems. The Ambient Air Directive (AAD) Limit Values are for sulphur dioxide (SO2), nitrogen dioxide (NO2), oxides of nitrogen (NOx), particulate matter (PM10 and PM2.5), lead (Pb), benzene (C6H6), and carbon monoxide (CO) are listed below in Table 7.1. The Air Quality Standards Regulations 2010 (Statutory Instrument, 2010, No.1001) (hereafter referred to as the Air Quality Regulations) implement the requirements of Directive 2008/50/EC.

  • Jinder Ubhi Dear Sadiq Khan, I Have Consulted with Members of The
    Jinder Ubhi From: Laurie Baker Sent: 27 February 2018 19:38 To: Londonplan Cc: Peter Heath Subject: New draft London Plan Dear Sadiq Khan, I have consulted with members of the London Geodiversity Partnership (LGP) and these are the comments of the Partnership on the geodiversity aspects of the draft London Plan: Comments on Policy G9 Geodiversity In general there is an improvement on this section of the previous London Plan. Policy G9 is divided into two parts. On Development Plans, Part A, 1) and 2) are identical to the previous wording; do you see the previous reference to London’s Foundations as superfluous in the policy. For development proposals, Part B says “where relevant” but this is unnecessary. In B 2), developments should also protect SSSIs. In paragraph 8.9.2, when referring to SSSIs it should say “Interest” not “Importance” The paragraph states that “London’s geodiversity Sites are shown in Figure 8.1”. However, it says “National/Regional Geodiversity Importance” and the LGP would like SSSIs to be shown. (Peter: Does the map layer I sent you from Natural England work for you?) As they are part of the Plan, LGP would like LIGS also to appear (with correct LF numbers) on figure 8.1. On Figure 8.1, although it says the reference numbers come from SPG 2012, they bear no relation to London’s Foundations. The numbering of sites in LF should be used. In the table below, I have tried to allocate the number given in figure 8.1 to show the problem. I have tabulated the sites below, with the new sites 60‐72 marked with red numbers.
