However, there are other phosphate inputsbesides those attributable to sewage works, and initiatives area underway to better understandthis issue and implement measures that will lead to a long-term reduction in phosphateconcentration in the river.MAJ/07 Page 129Core Policy 20Development in the SAC catchment should not have a significant effect upon the SAC supportthis wider agenda to protect the river, and developers of the strategic sites identified in thisStrategy will be required to mitigate against any increase in P levels that their developmentmay create. This may be through contributions to a Mitigation Strategy which will identify andimplement measures to reduce P levels in the SAC or on or near site measures to be agreedby the LPA. Measures will be secured contribute to any overall mitigation strategy throughSection 106 agreements. This mitigation strategy will identify and implement measures toreduce the phosphate levels in the SAC.Core Policy 20 Pollution and phosphate Levels in the Water EnvironmentIn order to protect groundwater and surface water quality and to avoid and reduce the potentialenvironmental effects on water quality in the River Avon Special Area of Conservation,development will need to incorporate measures during construction and operation that avoidand prevent pollution and mitigate potential disturbance effects. This may include appropriateschemes of mitigation, including consideration of suitable buffer zones along watercourses,habitat enhancements and river access management measures. will be required to mitigatepotential disturbance effects’.
