This area contains an introduction to nutrient neutrality in the River Camel catchment. It provides links to more detailed information about the implications for planning applications.
In 2021, Natural England issued guidance on phosphate pollution in the River Camel. This pollution can come from sewage treatment works, septic tanks, industry and farming. Too many phosphates can cause rapid growth of certain plants, which affects wildlife. Natural England feels the natural habitat of the River Camel is in an 'unfavourable' state because of this. Wastewater from new development can make things worse.
The Habitat Regulations 2017 help protect the River Camel Special Area of Conservation. The Local Planning Authority (LPA) is the competent authority under these Regulations. We must ensure that new development does not lead to more pollution. We can only approve those that are 'nutrient neutral' to reduce the risk of more harm.
Designing developments with the right mitigation measures can help prevent nutrient pollution. These measures can be on the site of the development or elsewhere in the river catchment area. Not all developers can offer on-site measures or negotiate off-site ones without help.
We have a team working on a long-term strategy to mitigate the impact of extra development. This will help developers with the mitigation they need to unlock paused developments. It will also help the Council progress with its key home-building plans.
In summary, the mitigation strategy includes:
- constructing wetlands
- upgrading household and campsite septic tanks/package treatment plants
- nature-based measures
The strategy will create a phosphate credit scheme. Planning applicants can buy credits to mitigate the phosphate pollution that development causes. This will help their plans progress.

Nutrient neutrality and planning applications
This page is the 'home' of Cornwall Council's phosphate calculator. This calculator identifies the impact of planning applications on phosphate pollution. It outlines the level of mitigation required for a period of 80 years.
This page also contains information about:
- how the issue could affect your site
- using the calculator
- next steps and validation requirements
- small scale thresholds and nutrient neutrality principles and guidelines.

River Camel phosphates mitigation strategy and policy
We have been working on a long-term strategy to mitigate the impact of extra development. This will help developers with the mitigation they need to unlock paused developments. The aim is to give developers confidence to continue investing in the area. It will help the Council progress it's key home-building plans. It will also provide other social, economic and environmental benefits for North Cornwall.
The strategy will create a phosphate credit scheme. Planning applicants can buy credits to mitigate the phosphate pollution that development causes.

- developing the strategy
- the mitigation measures we are planning
