Spill Control for Local Authorities and Public Sector — Compliance Guide
Local authorities and public sector organisations manage diverse chemical storage and handling risks across depots, highways operations, leisure facilities, schools, care homes, and administrative buildings. This guide covers the specific spill control obligations for UK councils and public sector bodies.
Council Depot Fuel Storage
Council vehicle depots typically store diesel fuel for fleet vehicles. Above-ground fuel storage must comply with the Oil Storage Regulations 2001 (England). Key requirements: bunded tank with 110% containment capacity; impermeable bund construction (concrete or steel); no drain valve without lock; fill point drip tray; overfill prevention valve. Many older council depots have single-skin tanks that require urgent upgrade. The EA has prosecuted several councils for legacy tank spills.
Highways Gritting — De-icer Storage
Winter road maintenance uses significant quantities of salt brine and liquid de-icers. Liquid de-icers (typically potassium acetate or sodium formate) have aquatic toxicity concerns — EA Pollution Prevention Guidelines apply to storage. Salt brine tanks require secondary containment if located near watercourses or drains. Salt/grit stores: no specific bunding requirement for solid salt, but site drainage must prevent salt washoff to surface water.
Leisure Centres — Pool Chemical Storage
Swimming pool water treatment involves chlorine-based chemicals that present significant COSHH risks. Key considerations:
| Chemical | Form | COSHH Risk | Storage Requirement |
|---|---|---|---|
| Sodium hypochlorite | Liquid (12.5%) | H314, H400 — generates Cl2 if mixed with acid | Separate from pH reducers, bunded |
| Hydrochloric acid (pH reducer) | Liquid (30-32%) | H314, H335 — NEVER MIX WITH HYPOCHLORITE | Completely separate storage, bunded |
| Trichloroisocyanuric acid | Tablets/granules | H302, H400 — oxidiser | Dry, ventilated, separate from flammables |
Schools — CLEAPSS and COSHH
State schools in England and Wales have a statutory duty to follow CLEAPSS guidance for science laboratories. CLEAPSS membership provides access to Hazcards (spill procedures), risk assessments, and supplier guidance. School employers (local authorities or academy trusts) must ensure adequate spill kits are maintained in all science laboratories and art rooms where hazardous chemicals are used.
Care Homes — CQC and Chemical Storage
Care Quality Commission (CQC) inspections assess chemical storage as part of safe care delivery. Key requirements: cleaning chemicals stored in locked storage away from residents; SDS available; COSHH assessments completed; staff trained in chemical handling; spill response equipment available in cleaning stores. CQC can require immediate action notices for unsafe chemical storage.
Public Sector Procurement
UK public bodies procuring spill control equipment should reference Crown Commercial Service (CCS) frameworks and ensure suppliers meet relevant standards. Products should carry ÜHP certification for secondary containment equipment, and suppliers should be able to provide technical support for COSHH compliance specification.
