CITB Managers Welfare Facilities and Environmental Legislation 3 — Questions and Answers
Question 1: What is the minimum headroom inside a site welfare facility such as a toilet block?
- 1.8 metres
- 2.0 metres (the general guidance for construction-related welfare units) (Correct answer)
- 1.5 metres
- No specific requirement
Correct answer: 2.0 metres (the general guidance for construction-related welfare units)
While no specific minimum headroom is prescribed in CDM 2015 for welfare units, HSE guidance recommends a minimum of 2.0 metres inside welfare facilities. This is consistent with the general Workplace (Health, Safety and Welfare) Regulations 1992 guidance on space and clearance.
Question 2: The Environmental Impact Assessment (EIA) Regulations 2017 require an EIA for certain construction projects. What is the purpose of an EIA?
- To assess the financial viability of the project
- To systematically identify and assess the potential environmental effects of a project before it is approved, and to propose mitigation measures to reduce significant adverse effects (Correct answer)
- To replace the planning permission process
- To identify health and safety risks for CDM purposes
Correct answer: To systematically identify and assess the potential environmental effects of a project before it is approved, and to propose mitigation measures to reduce significant adverse effects
An Environmental Impact Assessment identifies all significant environmental effects of a proposed project (on ecology, landscape, water, air, noise, cultural heritage), assesses their significance, and proposes mitigation. It must be considered by the planning authority before consent is given.
Question 3: What is the purpose of a Construction Environmental Management Plan (CEMP)?
- To satisfy RIDDOR reporting requirements
- To set out how environmental impacts during construction will be managed, monitored, and reported, typically required as a planning condition and covering topics including water, ecology, noise, dust, and waste (Correct answer)
- To replace the Construction Phase Plan under CDM 2015
- To document the environmental qualifications of site personnel
Correct answer: To set out how environmental impacts during construction will be managed, monitored, and reported, typically required as a planning condition and covering topics including water, ecology, noise, dust, and waste
A CEMP is a contractual and planning-condition document that sets out the site-specific environmental management measures for the construction phase, including responsible persons, monitoring and reporting arrangements, and emergency procedures for environmental incidents.
Question 4: Which of the following is a requirement under the Control of Pollution (Oil Storage) Regulations 2001?
- All oil must be stored underground
- Above-ground oil storage containers of more than 200 litres must have secondary containment of at least 110% of the largest container's capacity (Correct answer)
- Oil may be stored in any container provided it is labelled
- Secondary containment is only required for containers over 10,000 litres
Correct answer: Above-ground oil storage containers of more than 200 litres must have secondary containment of at least 110% of the largest container's capacity
The Oil Storage Regulations 2001 require secondary containment (bunding) for all above-ground oil storage containers over 200 litres (and for mobile bowsers over 200 litres used for plant refuelling). The bund capacity must be at least 110% of the largest container.
Question 5: Construction activity near a watercourse may require a Flood Risk Activity Environmental Permit. When is a permit required rather than an exemption?
- Whenever any construction work takes place near a watercourse
- When the activity is more complex or higher risk than those covered by the standard exemption categories — for example, work in, over, or under a main river or works affecting a flood plain that exceed the exemption thresholds (Correct answer)
- Permits are never required — only exemptions apply to construction
- When the construction project has a capital value over £1 million
Correct answer: When the activity is more complex or higher risk than those covered by the standard exemption categories — for example, work in, over, or under a main river or works affecting a flood plain that exceed the exemption thresholds
Many routine activities near ordinary watercourses can be registered as low-risk exemptions. More complex activities — work on or near main rivers, significant flood plain works, or works exceeding the volume/area thresholds for exemptions — require a full Environmental Permit from the EA.
Question 6: What legislation protects badgers and their setts in the UK?
- The Wildlife and Countryside Act 1981 only
- The Protection of Badgers Act 1992, which makes it an offence to wilfully kill, injure, or take a badger, or to disturb, damage, destroy, or obstruct a sett (Correct answer)
- The Environmental Protection Act 1990
- The Conservation of Habitats and Species Regulations 2017 only
Correct answer: The Protection of Badgers Act 1992, which makes it an offence to wilfully kill, injure, or take a badger, or to disturb, damage, destroy, or obstruct a sett
The Protection of Badgers Act 1992 provides specific protection for badgers and their setts. It is illegal to kill, injure, or take badgers, and to disturb, damage, or obstruct a sett without a Natural England licence. The offence applies year-round even when the sett is not in use.
