- In England, Natural England monitors the condition of special habitats and provides advice to local planning authorities. Nutrient neutrality refers to the advice Natural England have given to developers to ensure the amount of nutrient pollution (usually phosphates and nitrates) entering rivers does not increase as a result of new development.
- There is a legal requirement to keep pollution below prescribed levels in areas of particular ecological importance, such as Special Protection Areas or Special Areas of Conservation, and this applies to any areas which drain into a watercourse that ultimately flows into a protected area.
- Where these levels are exceeded, Natural England can put advice in place which means that Local Planning Authorities cannot lawfully grant permission for new development, unless they can satisfy themselves it will not cause further harm to the natural environment (i.e., they are nutrient neutral). Nutrient pollution neutrality advice is now in place in 74 areas and has effectively created a moratorium on new development.
- This amendment replaces Schedule 13 and amends the Conservation of Habitats and Species Regulations 2017, to state that local certain authorities/bodies, including local authorities, must assume that nutrients in waste water from proposed developments will not adversely affect the natural environment.
- In effect, this will overrule current nutrient neutrality advice and allow local authorities to go ahead with developments in areas where they are currently blocked.
LGA view: Our policy inquiry Stuck in neutral: a call for partnership working on river quality and water quantity set out a mix of recommendations for reducing water pollution at source, bringing forward mitigating schemes, and supporting partnership action.
New development is relatively small contributor of nutrient pollution. In 2021, the Environment Agency reported that about 70 per cent of pollution of nitrates in water came from agriculture, with the secondary contributor being sewage effluent at 25 to 30 per cent.
This amendment must be part of a package of measures to address the root causes of excess nutrients from agriculture and sewage.
Councils have been putting significant effort into mitigating the impact of nutrient and water neutrality, which allows planning permission for new developments to be signed off. However, these measures are only able to offset a small amount of the total amount of nutrient pollution entering our rivers.
The LGA has long called for the regulators and agencies, such as the Environment Agency, Ofwat and Natural England, to take a more proactive and stringent role in protecting rivers and preventing pollution at source. The fundamental issue is that the legislative and regulatory framework is failing to protect the environment from harmful levels of nutrients and tackle pollution at source, which over many years has led to poor water quality and environment damage.
Additionally, local solutions are urgently needed to address environmental risks and river pollution. We have called on Government to invest in a new model of “catchment nutrient plans”, backed by appropriate long-term funding, and give local authorities the flexibility to invest in locally available solutions to mitigate pollution and address pollution at source within river catchment areas. These plans would require strategic oversight from Government and include mechanisms to require the involvement of all key partners including Natural England, the Environment Agency, Ofwat, water companies and developers. These partnerships must be given the tools and resources to tackle the critical state of rivers and drive action to tackle the underlying causes of environmental damage.
Only 16 per cent of rivers are close to their natural state, according to Defra’s most recent annual report. We want to see the introduction of local level river restoration strategies, backed with the tools and funding to address existing pollution and restore the waterways to their natural state.
Local authorities need clarity from government on when this amendment would be implemented, as no date is specified. The Government has stated that their ambition is for house building to start on sites previously covered by nutrient neutrality advice within months. Councils need clarity over what will happen to current offsetting and mitigation schemes which are already in place, if the legal requirement for developers to participate in order to build new homes is removed.
It is disappointing that government has not announced any solutions for the areas where housebuilding is blocked by water neutrality advice. While this currently only affects a small number of councils there is an underlying concern over the scarcity of water, and how to meet the demand for housing growth in areas where water supply is under pressure. Government must step up engagement with local government on water supply issues.
