An Environmental Statement had to be prepared in support of the application for planning permission to construct and operate grid connection infrastructure associated with the Neart na Gaoithe Offshore Wind Farm located within East Lothian. Land Use Consultants Limited (LUC) with associated sub-consultant ARUP were commissioned by Mainstream Renewable Power Limited, on behalf of Neart na Gaoithe Offshore Wind Limited, to undertake a noise survey at Thorntonloch as part of the Environmental Statement. The purpose of the survey was to record the baseline noise levels in the vicinity of the proposed onshore construction site. The data was collected to understand the current noise level, and to inform the assessment of changes which might occur during the construction phase. completed Joanna Wright Land Use Consultants Principal in Charge 37 Otago Street Glasgow G12 8JJ United Kingdom glasgow@landuse.co.uk www.landuse.co.uk processor Mainstream Renewable Power Limited Project Manager 140 London Wall London EC2Y 5 DN United Kingdom info@neartnagaoithe.com www.mainstreamrp.com pointOfContact Stephanie Harper Arup Stephanie.Harper@arup.com.au originator Crown Estate Scotland +44 (0)131 260 6070 Quartermile Two, 2nd Floor, 2 Lister Square, Edinburgh EH3 9GL United Kingdom enquiries@crownestatescotland.com http://www.crownestatescotland.com custodian Crown Estate Scotland +44 (0)131 260 6070 Quartermile Two, 2nd Floor, 2 Lister Square Edinburgh EH3 9GL United Kingdom enquiries@crownestatescotland.com http://www.crownestatescotland.com distributor notPlanned Marine Environmental Data and Information Network NDGO0001 Cable Landfall The Crown Estate Renewable Energy Development Phases 2012-05-15 revision 1 Consenting Onshore area of search Other The Crown Estate Renewable Energy Development Areas 2012-05-15 revision 1 Marine Environmental Data and Information Network Marine Environmental Data and Information Network Restricted restricted restricted Restricted eng environment -2.516378 -2.3929770 55.937288 55.9720829 2011-08-02 2011-08-17 Data restricted Various Various https://www.marinedataexchange.co.uk/details/CES-248/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site. series Meteorological conditions during the unattended survey period were monitored; data affected by adverse weather conditions, e.g. high winds, have been discarded. Environmental noise loggers were located on residential properties representative of nearest affected dwellings to the proposed construction works. Five measurement locations were chosen in consultation with ELC to establish representative baseline noise levels. Loggers were located in acoustically hemispherical ‘free field’ conditions, at least 3.5 m away from any vertical reflective surfaces. The loggers were configured to measure and store data in fifteen minute samples. This enabled the time history information for ambient and background noise to be established at the measurement locations For construction noise assessment, ambient noise levels in the absence of the noise from the overhead lines have been used to determine construction noise threshold values at this location, as the baseline measurement was affected by this. The sound level meters were checked for correct calibration before and after each series of measurements. No significant fluctuation in level was recorded throughout each survey period. In addition to this, each SLM system used by Arup has a fully traceable calibration to national standards carried out on an annual basis
