CSCS Environmental Awareness 3

Question 1

What is the purpose of an Environmental Impact Assessment (EIA) for a major construction project?

Accepted Answer

To systematically identify, predict, evaluate, and mitigate the environmental effects of a proposed development before planning permission is granted, as required by the Town and Country Planning (Environmental Impact Assessment) Regulations 2017

Answer

Under the Town and Country Planning (EIA) Regulations 2017, certain types of major development must undergo an Environmental Impact Assessment before planning permission can be granted. The EIA process identifies likely significant environmental effects (noise, air quality, ecology, water, landscape, heritage), proposes mitigation measures, and is documented in an Environmental Statement submitted with the planning application.

Question 2

What are the legal requirements for managing surface water runoff from a construction site?

Accepted Answer

Surface water runoff must be managed using sustainable drainage systems (SuDS), silt traps, and settlement lagoons to remove pollutants before discharge — an environmental permit or exemption may be required from the Environment Agency for discharges to controlled waters

Answer

Under the Environmental Permitting Regulations 2016 and planning conditions, construction site surface water runoff must be treated to remove sediment, oils, and other contaminants before discharge. SuDS, silt fences, settlement lagoons, and oil interceptors are commonly used. A permit or registered exemption from the Environment Agency may be required for discharges to controlled waters (rivers, streams, groundwater). Uncontrolled discharges are a criminal offence.

Question 3

What is the 'polluter pays' principle in UK environmental law?

Accepted Answer

The person or organisation that causes pollution is legally and financially responsible for cleaning it up and any resulting environmental damage — this principle underpins the Environmental Protection Act 1990 and Environmental Damage Regulations 2009

Answer

The 'polluter pays' principle is a fundamental tenet of UK environmental law, enshrined in the Environmental Protection Act 1990 and the Environmental Damage (Prevention and Remediation) (England) Regulations 2009. The person or organisation responsible for causing pollution must bear the cost of cleanup, remediation, and any damage to the environment. On construction sites, this means the contractor is liable for pollution incidents.

Question 4

What precautions must be taken when demolishing a building to control environmental impacts?

Accepted Answer

A pre-demolition audit must identify materials for reuse/recycling, asbestos and hazardous materials must be removed first, dust and noise must be controlled, and a waste management plan must ensure proper disposal — all as required under CDM 2015 and environmental legislation

Answer

Demolition requires comprehensive environmental controls including: a pre-demolition audit to identify recyclable materials and hazardous substances; prior removal of asbestos (licensed where required); dust suppression (water spraying, screening); noise control within permitted hours; vibration monitoring near sensitive structures; a waste management plan for segregation and disposal; and pollution prevention measures for water and soil. CDM 2015 and environmental legislation apply.

Question 5

What must a construction site do to comply with the Environmental Protection Act 1990 regarding statutory nuisance from noise?

Accepted Answer

The site must take all reasonable steps to minimise noise nuisance, including working within permitted hours, using noise barriers and silenced equipment, notifying neighbours, and potentially obtaining a Section 61 prior consent from the local authority

Answer

Under the Environmental Protection Act 1990, noise from construction sites can constitute a statutory nuisance. Local authorities can serve abatement notices under Section 80 requiring noise to be reduced. Best practice includes: obtaining Section 61 prior consent (Control of Pollution Act 1974); working within permitted hours; using silenced plant; erecting acoustic barriers; monitoring noise at sensitive receptors; and maintaining a community liaison programme.
