East Anglia ONE Offshore Windfarm Construction Artificial Lighting Emissions Plan
September, 2016
5 Lighting Scheme 5.1 Introduction 51.
The objectives and performance outcomes for this CALEP are detailed below in Table 5-1. Table 5-1 Objectives and Performance Outcomes
OBJECTIVES
• To ensure temporary lighting installations are positioned so as to avoid light spill directly towards roads, residences and other potential viewing locations or ecological receptors.
• To ensure the potential impacts from light emissions on haul roads for mobile equipment are reduced so far as practicable.
• To utilise vegetation screens to minimise the impact of any light spill in the direction of roads, residences and other viewing locations or ecological receptors.
• To use directional lighting to reduce light spill and minimise light emissions from night time construction works to retain dark night skies.
• To ensure procedures are in place to record and effectively respond to any complaint in respect to lighting.
• To record and report the effectiveness of lighting emission controls.
PERFORMANCE OUTCOMES
• Sufficient lighting is provided on site to ensure that safety is not compromised.
• External lighting complies with relevant European and UK legislation, DCO conditions, environmental commitments as set out in the ES and environmental and construction best practice.
• The safety of external traffic on nearby roads is not affected by light sources on site.
• •
Impacts from light emissions from the site on nearby sensitive visual receptors is avoided or minimised where avoidance is not possible.
Impacts from light emissions from the site on ecological receptors is avoided or minimised, where avoidance is not possible.
• Complaints are responded to quickly and effectively. • The effectiveness of lighting emission controls are reported.
5.2 Lighting Requirements 52.
The majority of the construction activities will be conducted during daylight hours and will not require artificial lighting, unless daylight conditions are not sufficient for specific works to ensure safe working. It is anticipated that there would be some limited activities requiring work on a 24 hour basis, these works will require the use of artificial temporary lighting to ensure safe working. Artificial lighting will also be needed particularly during the winter months when daylight hours are much shorter and shorter than the specified working hours. For the highest structures within the substation lighting at higher elevations will be required.
53. The activities which may require artificial lighting at night are:
• Where continuous periods of operation are required, such as concrete pouring and directional drilling. • For internal fit out works associated with the onshore substation. • For the delivery of abnormal loads. • Works on the foreshore, if required. • Potential emergency works.
54.
The locations where activities that might require temporary construction lighting are described below and shown in Appendix 1:
• Temporary working areas along the cable route will only require artificial lighting during times where natural light is not sufficient to carry out the works. There will also be a requirement for artificial lighting on emergency works.
• At HDD locations there may be the need for lighting for 24 hour working (except at Work No. 21 or Work No. 26 as per the DCO Requirement).
• At Primary CCS sites there will be 24 hour onsite security presence and a need for artificial lighting for the duration of the works. At Secondary CCS sites security will be 24 hour with limited lighting specific to compound offices and parking area and will be programme dependant.
• Onshore substation compound and temporary works area.
