Councillors have expressed their sympathy after plans to convert an annexe in a Pembrokeshire village to a holiday let were refused due to general ongoing guidance about nitrogen levels in the Haven Waterway which is limiting development.

In an application recommended for refusal at the January 13 meeting of Pembrokeshire County Council’s planning committee, Mr J Burns sought a partly retrospective permission for the subdivision of an existing annexe at Briardale, Lamphey for holiday accommodation.

The application was before the committee rather than being decided by officers under delegated powers following a successful call at the October meeting of the council’s planning delegation panel.

It was recommended for refusal on the grounds it would result in an increase in nitrogen discharges draining into the Milford Haven Inner waterbody of the Pembrokeshire Marine Special Area of Conservation (SAC) “where features are known to be in unfavourable condition due to current evidence of both chemical and biological failure,” an issue, based on Natural Resources Wales guidance that is affecting many developments that have foul water drainage.

Pembrokeshire County Council recently backed sending a letter to the First Minister, conveying the authority’s “great concern over Natural Resources Wales’ recent river nitrates guidance,” which has “essentially placed a moratorium on certain types of development in Pembrokeshire”.

It says the area which development is required to demonstrate nitrogen neutrality is approximately 75 per cent of the county, including Haverfordwest, Narberth, Pembroke and Pembroke Dock, and amounts to approximately 35 per cent of the council’s future housing land supply.

Speaking at the meeting, agent Richard Banks said there had been no neighbour objections to the scheme, the building having already been on-site used as an annexe for family members for some two years.

He said the potential to use the existing facility for 365 days a year meant there was unlikely to be an increase in foul water drainage to the SAC.

Councillor Alec Cormack, who moved the recommendation of refusal, said: “My sympathy is with the applicant, and any applicant affected by this regulation.”

Officers also expressed sympathy to the applicant, but stressed the scheme, as a material change of use, brought in the need to comply with the NRW guidance, adding the scheme would, on the information presented, likely have an impact on the SAC through an increase in nitrates.

Members voted 11 to one in favour of refusal.

Cllr Alan Dennison expressed his sympathy the applicant was “just caught up in this farce regarding nutrients,” with committee chair Cllr Mark Carter stressing there was a need to find a solution to the ongoing issue: “I’m very sorry for all these people, these agents, these applicants, these builders, caught up in this.”

A nearby housing scheme for 50 homes on land near Gibbas Way, Pembroke was recently refused in part due to the ongoing nitrates issue.
