Standard rules consultation: revision of standard rules for non-hazardous sludge biological, chemical and physical treatment site (SR2008 No19)

Opens 10 Jul 2025

Closes 10 Oct 2025

Overview

The Environmental Permitting (England and Wales) Regulations 2016 allow us to make standard rules to reduce the administrative burden on business while maintaining environmental standards.

This consultation proposes:

  • Withdrawing and Archiving Standard Rule sets

The associated Generic Risk Assessment (GRA) has also been reviewed with respect to the proposed changes.

Before we do this, we must consult for a period of 3 months to allow the public, industry and anyone else with an interest to comment on the proposals. We must provide details and justification on why these changes are being made.

We propose to change the standard rules sets relating to biowaste treatment to:

  • reduce incidents caused by the biowaste sector, including fires and odour nuisance
  • improve poor performance
  • improve contribution to a more sustainable and circular economy
  • contribute to reducing the impact on climate change
  • remove old rule sets that are not being utilised

By doing this we will limit negative impacts on human health, communities and the environment.

Further details of how the proposed changes will meet these objectives can be found below:

Reducing incidents and improving poor performance

We have reviewed the evidence provided by the Environment Agency that the cause of incidents and poor performance in England & Wales are mainly due to:

  • inadequate design and poor construction standards
  • lack of operational process control
  • failure to have or follow an effective management system
  • deficient maintenance systems
  • inadequate pre-acceptance and acceptance checks, including unacceptable levels of feedstock contamination

We came to this conclusion by:

  • reviewing the responses to the EA Call for Evidence consultation in 2018
  • reviewing our compliance data on AD and composting sites

Contributing to a sustainable and circular economy

Recovering organic waste for soil benefit replaces the reliance on chemical fertilisers and decreases the dependence on peat.

Our objectives are to:

  • increase the use of food waste as a resource
  • replace chemical fertiliser through waste recovery

As set out in the government strategy for a circular economy

We will also strive to meet the government's objectives for greenhouse gases (specifically those linked to the waste sector and reducing Greenhouse Gas Emissions) as set out in their:

Reducing the impact on climate change

This sector can have a positive effect on climate change by:

  • reducing the deterioration in soil quality
  • capturing and storing carbon
  • producing energy from AD

However, Natural Resources Wales must ensure:

  • emissions are controlled, such as odour, bioaerosols, greenhouse gases and ammonia
  • there is no risk to water, air, soil, plants or animals

 

Why your views matter

Who this will be of interest to?

We think this consultation will be of particular interest to:

Operators of the non-hazardous sludge biological, chemical and physical treatment site standard rules set: This is your opportunity to ensure the that the revised rules work for you and your industry as well as providing the necessary protection to the environment and human health.

Other operators, trade associations and businesses: this is your opportunity to ensure that the revised rules work for you and your industry as well as providing the necessary protection to the environment and human health.

Other regulators, the public, community groups and non-governmental organisations with an interest in environmental issues: this is your opportunity to ensure that the revised rules provide the necessary protection to the environment and human health, whilst still being useful to industry.

Existing holders

If you currently operate under a standard rules included within this consultation, as a result of any changes made, you will be required to take one of the following actions:

  1. Upgrade your site to meet the new rules set standards.
  2. Apply to vary your activity to a bespoke permit.
  3. Apply to surrender the permit.

Important: Even if an operator has ceased or never commenced operations, subsistence fees will continue to accrue until their permit is formally surrendered. See: Natural Resources Wales / Apply to surrender (give up) all or part of a waste permit

The following headings outline the proposed changes along with the rationale behind them. We suggest that you compare the current Standard Rules sets against the proposed drafts within the links section of this consultation.

Withdrawn and archived standard rules sets

SR2008 No 19: non-hazardous sludge biological chemical and physical treatment site

This permit currently has one holder. This permit is currently available to new applicants; however, we propose to Withdraw and Archive this permit so that it is no-longer available to new applicants.

We believe that withdrawing and archiving the last remaining Standard Rules set available will contribute to achieving the objectives of this consultation. 

Due to the low utilisation of this rule set, as evidenced by the minimal number of active permit holders, we anticipate a negligible impact on business.

New applicants seeking a Permit to undertake a new activity at a new site will need to obtain Bespoke permits will ensure that future permits are tailored to the specific operational needs, waste streams, and site setting of specific operations will ensure risks are adequately controlled and mitigated.

We’re not proposing any other changes to this rules set.
