Construction sites are among the highest-risk environments for environmental pollution incidents in the UK. With fuels, oils, concretes, cement, and a range of chemical substances in use across dynamic, often exposed sites, the potential for spills reaching watercourses, groundwater, or the public sewer is significant. The Environment Agency (EA) and local planning authorities increasingly require formal Environmental Management Plans (EMPs) as a condition of planning consent or environmental permit — and spill control is a central element of every EMP.
The Regulatory Framework
Construction site operators must comply with several overlapping legislative requirements:
- Environmental Permitting (England and Wales) Regulations 2016 — applies to water discharge activities and waste management on site
- Water Resources Act 1991 (as amended) — prohibits causing or knowingly permitting water pollution; enforcement can lead to unlimited fines and prosecution
- Control of Pollution Act 1974 — governs noise and site runoff in certain circumstances
- COSHH Regulations 2002 — applies to all hazardous substances used on site, including fuels, cement, and cleaning chemicals
- Construction (Design and Management) Regulations 2015 (CDM) — requires Principal Contractors to manage health, safety, and environmental risks systematically
What is an Environmental Management Plan (EMP)?
An EMP is a formal document that sets out how a construction project will manage its environmental impacts throughout the build programme. It is typically required by the EA, local planning authority, or as a condition of a groundworks or remediation permit. A robust EMP covering spill control will include:
- Site drainage plan showing drain locations and outfall destinations
- List of all hazardous substances on site with volumes and storage arrangements
- Spill risk assessment for each substance
- Spill response procedures and assigned responsibilities
- Location and specification of spill kits, drain covers, and bunding
- Incident reporting procedure (including EA reporting obligations)
- Environmental monitoring plan (turbidity, pH checks for watercourse proximity)
EA Reporting: When Are You Required to Notify?
Any spill or incident that causes, or has the potential to cause, water pollution must be reported to the EA via the 24-hour incident hotline (0800 80 70 60). Failure to report is itself an offence under the Environmental Permitting Regulations. Do not wait to assess the full impact — report immediately and initiate containment simultaneously.
Spill Control Equipment Requirements for Construction Sites
| Risk Area | Recommended Equipment | Standard/Guidance |
|---|---|---|
| Fuel bowser / plant refuelling | Drip trays, mobile spill kits, bunded refuelling areas | EA PPG 28, PPG 7 |
| Site drainage outfalls | Drain guards, silt socks, inflatable stoppers | EA Pollution Prevention Guidance |
| Concrete washout areas | Designated washout bays, contained drainage | EA Construction Site Guidance |
| Chemical storage areas | Bunded stores, COSHH cabinets, absorbent pads | COSHH Regulations 2002 |
| Site entrance/wheel wash | Silt traps, filter socks, sediment control | Local planning conditions |
Practical Spill Control on Site
Every construction site should maintain a minimum provision of spill response equipment appropriate to the substances present. For a typical civil engineering site, this will include hydrocarbon spill kits at each plant refuelling point, drain covers and stoppers for all surface water drainage points, and a wheeled spill response unit at the site cabin for larger incidents.
All spill kits should be inspected weekly, clearly labelled, and restocked promptly after any use. Site inductions must include spill response procedures — and this should be documented.
For bunded fuel storage, the minimum requirement under EA guidance is that the bund holds 110% of the largest tank capacity. Our range of spill pallets and bunded containment is available in sizes to suit IBC tanks, standard drums, and fuel containers commonly used on construction sites.
