CSCS Environmental Awareness 3

Question 1

What is the purpose of an environmental impact assessment (EIA) on a large construction project?

Accepted Answer

To identify and evaluate the likely significant effects of the project on the environment before work begins

Answer

An EIA identifies potential environmental effects before work starts so that mitigation measures can be designed into the project.

Question 2

Which of the following best describes 'contaminated land' in a construction context?

Accepted Answer

Land where substances in or under the ground pose a risk to health, property, or the environment

Answer

Contaminated land contains hazardous substances — such as heavy metals or hydrocarbons — that pose risks and require specialist remediation.

Question 3

What action should a site operative take if they notice diesel leaking from a generator onto bare soil?

Accepted Answer

Stop the generator, contain the spill with absorbent material, and report it immediately

Answer

Immediate containment prevents soil and groundwater contamination; reporting ensures proper cleanup and incident recording.

Question 4

Why is it important to segregate waste into separate skips on a construction site?

Accepted Answer

Segregation enables more materials to be recycled and reduces disposal costs

Answer

Separating waste streams (timber, metal, concrete, plastics) maximises recycling rates and lowers landfill tax costs.

Question 5

Which of the following activities requires an environmental permit issued by the relevant authority?

Accepted Answer

Discharging treated water from a construction site into a watercourse

Answer

Discharging any water to a watercourse requires a permit from the environmental regulator (e.g., EPA or state authority) to control pollution.
