Nutrient Neutrality

About Nutrient Neutrality

Alongside all other local planning authorities in Norfolk, the council received a letter dated the 16th of March 2022 from Natural England concerning nutrient pollution in the protected habitats of the River Wensum Special Area of Conservation and the Broads Special Area of Conservation and Ramsar site. The letter advised that new development within, or draining into, the catchment of these habitats comprising overnight accommodation, or any development not involving overnight accommodation but which may have non-sewerage water quality implications, has the potential to cause adverse impacts with regard to nutrient pollution. Such development includes, but is not limited to:

New homes
Student accommodation
Care homes
Tourism attractions
Tourist accommodation
Permitted development (which gives rise to new overnight accommodation) under the Town and Country Planning (General Permitted Development) (England) Order 2015
Any development not involving overnight accommodation, but which may have non-sewerage water quality implications.

The Conservation of Species and Habitats Regulations 2017 require local planning authorities to ensure that new development does not cause adverse impacts to the integrity of protected habitats such as the River Wensum or the Broads prior to granting planning permission.

The council has worked closely with its neighbouring authorities, as well as with Natural England and Anglian Water, to provide a platform which will enable developers to buy credits to mitigate for the impact of nutrients. Any mitigation that releases credits needs to be in place before any dwellings are occupied, and be in place for at least 80 years.

Norfolk Environmental Credits

For those unable to access on-site mitigation solutions or those required to connect to mains drains under the drainage hierarchy, momentum is now gathering for credit purchase options with Norfolk Environmental Credits. Through the Nutrient Neutrality Mitigation Fund, funds are available to allow homeowners to upgrade their existing septic tanks to more efficient package treatment plants (PTP). This releases credits that can be purchased.

If you need to purchase credits and want to explore the options available please register your interest directly withNorfolk Environmental Credits (opens new window).

There are several routes to resolving nutrient neutrality. Other options are available to applicants to secure their own mitigation through negotiation with other landowners or on-site mitigation
