Requirement discharge application process
The consultation process for discharge of requirement applications relevant to the Sizewell C Development Consent Order (DCO) process differs to that for planning applications submitted under the Town and Country Planning Act 1990.
East Suffolk Council (ESC) carries out the discharge of requirement process in accordance with what is set out in the DCO, including consulting in accordance with each specific requirement. This does not require town or parish councils or adjacent/neighbouring landowners to be formally consulted, this is in the same way that the discharge of condition process under a planning application does not.
ESC is required to consult Suffolk County Council (SCC) on all discharge of requirement applications, set out in overarching Schedule 24(1)(4) of the DCO. This also applies to SCC; SCC must consult ESC on discharge of requirement applications where SCC is the discharging authority.
ESC receives and validates applications for discharge of requirement applications from SZC Co. which are then made available for the public to view on Public Access by searching for the reference number (discharge of requirement applications will end in /DRR). All submission documents under requirements will be publicly available except where privacy reasons or confidentiality limits this. The DCO does not require site notices or other publication of specific discharge of requirement applications.
Town and parish councils or any other interested person/group can make representations on discharge of requirement applications if they choose, though they will not receive a formal consultation from ESC. This can be done through Public Access or by emailing our planning team. We encourage all interested parties to use the Public Access system to set up automatic notifications for the Sizewell C project, which can be specifically tailored for certain key words, search terms, or geographical area. This will ensure you are notified when an application is received, determined, or the status changes.

DC/24/4508/DRR - Discharge of Requirement 39 (Rail Noise Mitigation Plan) of Sizewell C Development Consent Order - Rail Noise Mitigation Plan East Suffolk Line Little Bealings To Sizewell Suffolk. Status = Awaiting decision
No current details.
The Sizewell C Code of Construction Practice secured by Requirement 2 of the Development Consent Order secures construction works being undertaken in accordance with all relevant legislative controls, construction health, safety, and environmental standards, and other relevant best practice methods. The aim of the Code of Construction Practice is to provide a clear and consistent approach to the control of Sizewell C construction activities on the Main Development Site to maintain satisfactory levels of environmental protection and take all reasonable steps to mitigate and minimise disturbance from construction activities.
In addition to the controls set out in the Code of Construction Practice, a site specific Noise Monitoring and Management Plan must be prepared to detail the monitoring and management arrangements for noise for each site. Noise Monitoring and Management Plans in general accordance with the principles set out in the Draft Noise Monitoring and Management Plan (Appendix A to Part C of this CoCP) must be submitted to and approved by ESC.
The Noise Monitoring and Management Plans provide a mechanism for the submission and agreement of Bespoke Mitigation Plans. Where, despite the use of best practicable means (as defined by Section 72 of the Control of Pollution Act 1974), it is anticipated that the construction works will exceed the anticipated noise levels set out in each Noise Monitoring and Management Plan, or the vibration thresholds stated therein, a Bespoke Mitigation Plan will be submitted to ESC for approval.
Details of works likely to require a Bespoke Mitigation Plan and a draft of the plan will be provided to ESC at least 28 days prior to the start of the works, to include predicted noise or vibration levels at the closest sensitive receptors, proposed mitigation, and a scheme for notifying local residents. The purpose will be to agree measures to reduce noise as far as reasonably practical for particularly noisy activities. If appropriate, the Bespoke Mitigation Plan can include revised noise thresholds.
