The energy company behind plans for a nuclear power plant in east Suffolk has been called upon to reconsider its “inappropriate” transport proposals associated with the project.

The chairmen of Hacheston, Marlesford and Parham parish councils have written to EDF Energy, expressing concerns about its park and ride proposals for a site near the three villages, to ferry workers to Sizewell C during its construction.

The letter highlights the “overwhelming opposition” expressed by the public at a consultation meeting organised by EDF in Hacheston last month, on the grounds of the scheme’s proposed location on “open agricultural land overlooking the sensitive River Ore Valley”.

Signed by Graeme Hall, of Hacheston; Annette Gray, of Parham, and Lord Marlesford, the letter continues: “A piece of important Suffolk landscape is therefore entirely inappropriate for such a development, which would represent a major intrusion probably 24/7 for an extended period, possibly as long as 10 years, into the communities, especially Marlesford.”

EDF’s decision to extend the potential development site towards Marlesford, and its alleged failure to consult with the village, is also highlighted as a concern.

“We believe that you would be wise to reconsider your entire transport plan for Sizewell,” the letter states.

Dan Poulter, MP for Central Suffolk and North Ipswich, who was copied into the letter, has added his opposition to EDF’s proposals, claiming the loss of “prime agricultural land” is unacceptable when more suitable brownfield sites are available closer to Sizewell. “EDF needs to go back to the drawing board,” Dr Poulter said. “The county council must not allow EDF to run roughshod over the views of the people of Suffolk when they take this forward in further negotiations with the company.”

EDF has highlighted its work to minimise local disruption by building a jetty and enhancing the local rail network to take bulk materials and temporary accommodation for workers to cut journeys.

A spokesman said the company was undertaking a “robust transport assessment” to inform its Sizewell C project. “This is detailed and important work, which takes into account objective data, responses to consultation and planning policy guidance.”
