Dear Carmarthenshire Council,
On 24 March 2015 National Grid concluded a formal investigation into the serious safety concerns raised in regard to the proposed 27.1m tall wind turbine which was shown on the plans to be about 18m from overhead conductors bearing 11,000V (E/28634 PantYBryn Wind Turbine).
You may recall (from other FOI) that Carmarthenshire County Council's planning department claimed that they had not received a response when they tried to contact National Grid (first mis-described as National Power). More recently the department let slip that they had in fact received an email redirecting their enquiry, a copy of which was finally disclosed under compulsion of the Freedom of Information Act.
Members of National Grid's Asset Protection Team were appalled at the ignorance shown by Carmarthenshire County Council's planning department, the risk to public/community safety, and very concerned with the threat posed to their colleagues in the field who may have to had deal with the aftermath of an avoidable accident.
Carmarthenshire County Council's planning department has described National Grid as a "statutory undertaker". As such, working in a potentially dangerous and highly regulated field, the planners should not be surprised to find National Grid working to strict specifications and defined protocols. In addition to providing a copy of the Energy Networks Association's "Separation between Wind Turbines and Overhead Lines/ENA Engineering Recommendation LXX" (which came into effect from 1st April 2012), they outlined the following formal protocol:-
a) Once every year, National Grid writes to each Local Planning Authority to confirm that the registered contact details are correct.
b) Once every year, National Grid provides each LPA the locations of its assets in the form of "Shape Files" suitable to be imported into each LPA's GIS system.
c) Once every five years, National Grid physically visits each LPA in the country to ensure that the registered details are correct, remind the LPA of its duties in respect of National Grid operated infrastructure, offer advice, answer questions etc.
d) National Grid expects that every planning application is examined by the LPA with the most recent version of its GIS Shape Files.
e) National Grid expects that every planning application submitted is validated by a competent person visiting a proposed site, noting that the maps, plans and site conditions match. This includes looking out for obvious signs of overground infrastructure in the vicinity, such as 10.5m wooden poles/pylons bearing conductors in a 1.2km line etc.
With reference to the above protocol described by National Grid's Asset Protection Team, please can you provide all information that the Council holds for the period between 1 January 1998 and 13 March 2015 in respect of:
1) Dates and copies of correspondence exchanged between Carmarthenshire County Council and National Grid.
2) The dates that GIS Shape Files were received from National Grid, the file size and SHA256 message digest for each, and the date applied to the LPA's GIS platforms used in Crescent Road (it may be easiest if you just output the logs from revision control system for these elements into a human readable form for the latter limb).
3) Dates, venues and names of attendees for meetings held between the LPA and National Grid.
4) The method of working prescribed by the LPA to safely compare applications received with electronic/desktop records.
5) The name, job title and professional accreditation of each employee that Carmarthenshire County Council considered to a be defined as a competent person for the purpose of this role.
Additionally, please can you confirm if Carmarthenshire County Council now holds a copy of the ENA's "Separation between Wind Turbines and Overhead Lines/ENA Engineering Recommendation LXX" document. National Grid is a transmission licensee as defined by the 1989 Electricity Act, this document is the national guideline. If so, on which date did the Planners read sections 4 & 4.1 (Separation Between Wind Turbines and Overhead Power Lines & Toppling Distance) and Annex B (Diagrammatic representation of falling clearances)?
