A substance or parameter that is determined analytically, e.g. arsenic concentration in soil, pH of water, concentration of a particular gas in air quality modelling.

An Order made under the Planning Act 2008 granting development consent for a Nationally Significant Infrastructure Project

The Electrical Connection is not part of the Application for the Scheme, but will be required for the export of electricity. A number of realistic assumptions have been made regarding the electrical connection works as set out below:

• The Electrical Connection is likely to consist of underground cabling between the Scheme’s electrical switchgear located within the Power Station Complex and the existing Marchwiel substation, located on Abbey Road on the Wrexham Industrial Estate.

• The wider existing electrical distribution network will also need upgrading to accommodate the new generation. This is likely to consist of works to the existing Marchwiel substation, re-stringing of existing pylons between Legacy and Wrexham substations, replacement of the existing portal frame towers between Legacy and Marchwiel substations, and laying of underground cables. Once completed the electrical network which currently serves the Wrexham Industrial Estate will have increased capacity and resilience from that which exists presently.

UK government's policy to reform the electricity market. The policy aims to deliver low carbon energy and reliable supplies for the UK, while minimising costs to consumers.

EMFs comprise electric and magnetic fields. Electric fields are the result of voltages applied to electrical conductors and equipment. Magnetic fields are produced by the flow of electric current.

Breeding Birds

5.33 To ensure that no offences are committed under the Wi1981, any preliminary site clearance of vegetation suitable for supporting nestibirds will be undertaken outside of the nesting bird season (which is generally considered to be February to September inclusive, but is dependent on species and seasonal variation).

5.34 Should any clearance be required during the nesting bird season, a detinspection for nesting birds should be carried out, by a suitably experienced ecologist, no more than 24 hours prior to any clearance being undertaken. This minimises opportunities for nest building between the inspection and the start of any clearance.

• Solid hoardings will be used to aid in visually screening the construction activity; and

• The construction site will be maintained in a clean and tidy manner, including covering of stockpiles

It will ensure that arrivals and departures are spread as evenly as possible over the course of the working day;

• All construction plant and vehicles will be parked onhighway;

• A system will be implemented for preabnormal loads to the authorities and the local community, and provide escorts where required;

• A wheel wash facility will be provided for all construction vehicles leaving the WEC Site. This will minimise the level of dust and dirt being transferred to the public highway. Site entrances and adjacent public highway will be and swept clear if required;

• A 24 hour contact number and a named member of staff (the community liaison manager) will be made available to the public to report any issues or concerns relating to construction traffic. This will allow nonroutes and inappropriate driving to be reported and addressed;
