20.3.3 Embedded Mitigation
16. Mitigation measures which are embedded into the project design and which are relevant to air quality are listed in Table 20.4. General mitigation measures are provided first, and apply to all parts of the onshore electrical transmission works. Specific mitigation measures, which apply to either the landfall, onshore cable route or converter station, are described separately thereafter. An Outline Code of Construction Practice will be developed and submitted alongside the final Environmental Impact Assessment (EIA).
17.
It should be noted that the embedded mitigation measures below were taken from the East Anglia ONE ES and therefore the 2006 Greater London Authority and London Councils guidance document was utilised. The Institute of Air Quality Management (IAQM) released new guidance on the assessment of construction dust impacts in 2014 (IAQM 2014), which was utilised in the assessment of construction dust impacts as a result of East Anglia THREE.
Table 20.4.Embedded Mitigation in relation to Air Quality Parameter
General
Construction Construction and decommission works would be undertaken in accordance with the Greater London Authority and London Councils best practice guidance document (Greater London Authority and London Councils 2006) on controlling emissions from construction sites. Control measures which would be included within final Code of Construction Practice would include:
effective barriers would be erected around dusty activities or the site boundary;
Preliminary Environmental Information May 2014
no bonfires would be allowed on site;
machinery and dust-generating activities would be located away from sensitive receptors;
no vehicles would be allowed to idle on site; vehicles leaving site would be washed if necessary;
