Phosphates
In January 2021, Natural Resources Wales (NRW) published evidence that showed over 60% of riverine Special Areas of Conservation (SAC) waterbodies failed against phosphorus standards. As a result of these failings, NRW issued planning advice to avoid further deterioration in environmental capacity where new developments have the potential to affect phosphorus sensitive riverine SACs and achieve ‘nutrient neutrality’.
The advice from NRW relates to riverine SACs whose drainage catchments extend into Carmarthenshire, namely the Afon Teifi, Afon Tywi, Afon Cleddau, River Wye and River Usk. Of these five waterbodies, only two are affected by the proposed housing allocations in the plan draining to either the Afon Teifi or Afon Tywi.
The Council has sought to reduce the number of housing allocations in the Afon Tywi to six sites (102 units) and fifteen sites (189 units) in the Afon Teifi. The impact of these reductions has reduced phosphorous levels by 43% and 49% respectively in each of the waterbodies. This reduction, coupled with amendments to Policy CCH4 and the availability of land for potential wetland creation to promote the natural uptake of phosphates in Carmarthenshire, have all been screened as part of the Councils Habitats Regulations Assessment (February 2023) and concluded that the plan will have no adverse effect on the integrity of European sites. The delivery of allocated sites and implementation of long-term mitigation measures is for the statutory bodies of NRW and Welsh Water (WW) to comment in more detail.
