Hazardous substances

Hazardous substance consent

The role of hazardous substances consent

The planning system deals with preventing and limiting the consequences of major accidents in three key ways:

•
via hazardous substances consent (HSC). Owners and operators wishing to hold stocks of specified hazardous chemicals and similar substances on, over or under land above a threshold quantity must obtain an HSC from the relevant hazardous substances authority. See Practice Note: Hazardous substance zones and consent
•
handling development proposals around hazardous installations, and
•
dealing with hazardous substances in plan-making

See Practice Note: Hazardous substances and planning.

The basis of statutory control

HSCs are regulated by:

•
the Planning (Hazardous Substances) Act 1990 (P(HS)A 1990)
•
(in England) the Planning (Hazardous Substances) Regulations 2015 (PHSR 2015), SI 2015/627
•
(in Wales) the Planning (Hazardous Substances) (Wales) Regulations 2015 (PHSWR 2015), SI 2015/1597
•
the Control of Major Accident Hazards Regulations 2015, SI 2015/483

See Practice Note: Hazardous substance zones and consent.

Defra announces measures to accelerate development of offshore wind projects

The Department for Environment, Food and Rural Affairs (Defra) has announced measures to accelerate the development of offshore wind projects in the UK. The government is streamlining the consenting process for up to 13 major offshore wind projects, potentially generating 16GW of electricity and unlocking £20-30bn of investment in homegrown clean power. These changes will enable the government to designate new or extend existing Marine Protected Areas to offset impacts to the seabed caused by offshore wind development, preventing delays previously caused by insufficient environmental compensation agreements, with costs funded by developers through the Marine Recovery Fund. Any new designations of Marine Protected Areas will adhere to the existing legislative process, including consultation with affected industries and communities.
