Guidance

Get voluntary remediation advice for contaminated land and groundwater

You can use the voluntary remediation advice service to get more detailed site-specific regulatory advice where land contamination has impacted on controlled waters.

Applies to England

Who can use this service

This service is restricted to sites where land contamination has impacted on controlled waters. Controlled waters include territorial and coastal waters, inland freshwaters such as rivers, lakes and ponds, and groundwater contained in underground strata.

You can use this service if your site:

  • sits outside any spatial planning application or discharge of condition consultation
  • is not regulated under the Environmental Permitting Regulations
  • is not subject to a Part 2A determination, environment damage regulations remediation notice or anti-pollution works notice

The Environment Agency expects you to be a competent person and strongly recommends following the Land Contamination Risk Management (LCRM) guidance when dealing with land affected by contamination, contaminated soils and groundwater.

What you can get advice on

The voluntary remediation advice service is advisory only. The developer or landowner is responsible for making sure a contaminated site is safe to develop and occupy.

You can ask us to provide regulatory and technical review of the work that has been carried out by your competent environmental consultants. We will assess if the site has an acceptable or unacceptable risk of pollution to the water environment.

The voluntary remediation advice service can review documents you have prepared using the LCRM guidance, such as:

  • preliminary risk assessment
  • conceptual site models
  • site investigation proposals or results
  • generic quantitative and detailed quantitative risk assessments
  • remediation options appraisals
  • remediation strategies
  • remediation method statements
  • monitoring proposals
  • verification reports

What the service cannot help with

The voluntary remediation advice service cannot provide comments on or confirm:

  • you do not need a permit
  • you meet the general binding rules for discharges of wastewater to surface water or ground
  • your documents will be acceptable for future planning or environmental permit applications
  • work associated with definition of waste, radioactive substances or hydraulic fracking

How much it costs

The initial review costs include 5 hours of work to check your submission and identify the nature and amount of technical and legal input required to carry out the full technical assessment.

If you submit multiple documents or need a more detailed assessment, the Environment Agency will send you an estimate of how many hours it will take to complete.

The fees will be invoiced using the current costs as detailed in the Environment Agency’s fees and charges.

How to request advice

  1. Contact the groundwater and contaminated land team for your area in the Contact the Environment Agency section.

  2. If the service can help, you will receive a copy of the terms of service, the charging agreement, and an invoice for the interim fee (5 hours plus VAT). You must pay the interim fee before the voluntary remediation advice service can start work on your request.

  3. When you have paid the interim fee, the voluntary remediation advice service will assess your submission.

  4. You will receive monthly invoices by email for completed work.

  5. Once the review is complete and all invoices are paid, the team will email you a letter explaining the detailed technical review and the outcome. This includes whether the Environment Agency needs to use other regulatory powers to deal with the pollution risks on the site.

The Environment Agency may send you an updated time and cost estimate to sign and return before they can continue your assessment. This may be because:

  • more information is needed to complete the assessment
  • the assessment is more complex than first estimated

If you do not pay invoices on time, the service will stop their technical review and may end the contract. There is more detail in the terms and conditions for using the voluntary remediation advice service.

Check if the service is available in your area

The voluntary remediation advice service may not always be available to take on work, depending on local resources and priorities. Contact the groundwater and contaminated land team for your area first.
