Planning and Environment Decisions Wales (PEDW) has updated its significant infrastructure project (SIP) guidance collection, adding seven guides on working with public bodies during infrastructure consenting in Wales. The overarching guidance advises early engagement and states that applicants must formally consult statutory or specialist consultees at the pre-application stage and should continue discussions where issues remain unresolved. It covers public bodies' roles in environmental impact assessment scoping, the examination of applications and the discharge of Infrastructure Consent Order requirements. Applicants should use statutory and discretionary advice services where available and discuss potential cost-recovery fees at the outset. Six accompanying guides cover Natural Resources Wales, the Health and Safety Executive, the Office for Nuclear Regulation, Cadw, Heneb, the Royal Commission on the Ancient and Historical Monuments of Wales, the Welsh Government's Land Quality Advice Service and the Welsh Government Common Land Team. They address environmental assessments, major accident hazards, nuclear regulation, heritage protection, agricultural land classification and common land.
