Wildlife experts have raised fresh questions about plans for a "super-dairy" in Lincolnshire.

A formal consultation period on plans to create the 8,100 cow unit at Nocton, near Lincoln, ended on Friday but since then a further 104 comments have been added.

This takes the overall total of people and organisations having their say on the proposal to more than 600.

These include detailed observations from some major environmental groups.

The Environment Agency has raised concerns that the dairy could pollute a limestone aquifer.

Agency spokesman Rita Penman said: "It's up to anyone putting in an application to show that their consultants have proved there isn't any type of risk.

"Groundwater will travel and can affect a large area, so you have to ensure there won't be any contamination, period.

"I don't know if the developers didn't recognise what they needed to provide – it should have been fairly clear.

"But at this stage we need more information, and until then our objection stands."

But it's not just the quality of life for wildlife which is causing consternation.

In a letter to North Kesteven District Council's principal planning officer Philip Rowson, the chair of Nocton Parish council, Elaine Storr said they had "urgent concerns" about the proposals.

"Such massive dairy units have been constructed and operated in the USA and have caused considerable problems to neighbours even two miles away with particularly strong smells, flies and ground and surface water pollution.

"We are very concerned that the same problems should not be allowed to occur here."
