Environmental Awareness Flashcards

What are the requirements for managing asbestos waste as part of environmental compliance on a demolition project?

Answer: Asbestos waste must be kept completely separate from other waste, double-wrapped in labelled bags or sheeting, transported by a specialist registered carrier with hazardous waste consignment notes, and disposed of at a licensed hazardous waste landfill cell

Asbestos waste is classified as hazardous waste under the Hazardous Waste Regulations 2005. It must be completely segregated from other demolition waste, double-wrapped in labelled asbestos waste packaging (red-striped bags or 1000-gauge polythene), accompanied by hazardous waste consignment notes, transported by a specialist registered carrier, and disposed of at a landfill site with a specific asbestos cell. Mixing asbestos with general waste is a criminal offence.

What is the Environment Agency's role in regulating construction site activities in England?

Answer: The Environment Agency regulates water discharges, waste management, flood risk, contaminated land, and pollution prevention on construction sites — it issues environmental permits, conducts inspections, and can prosecute for environmental offences with unlimited fines

The Environment Agency is the principal environmental regulator in England. On construction sites, it regulates: water discharge activities (permits under the Environmental Permitting Regulations 2016); waste management and disposal; contaminated land remediation; flood risk management; and pollution prevention. It has powers to inspect sites, serve enforcement and suspension notices, and prosecute offenders with penalties including unlimited fines and imprisonment.

What sustainable practices should a construction site adopt to reduce its carbon footprint?

Answer: Using fuel-efficient plant, minimising vehicle movements, switching to electric or hybrid machinery, reducing waste through prefabrication, sourcing materials locally, using renewable energy for site offices, and implementing idle-time shutdown policies for plant and equipment

The Construction (Design and Management) Regulations 2015 and PAS 2080 encourage carbon reduction throughout construction. Practical measures include: fuel-efficient and electric/hybrid plant; consolidated deliveries to reduce vehicle movements; prefabrication to reduce on-site waste; local material sourcing; renewable energy for temporary accommodation; idle-time shutdown policies; and LED site lighting. Many clients now require carbon reporting as part of contract requirements.

What is the requirement for tree protection on construction sites where existing trees are to be retained?

Answer: Trees to be retained must be protected with fencing at or beyond the root protection area (RPA) as specified in BS 5837, with no storage, vehicle parking, excavation, or changes in ground level within the protected zone — breach of tree protection conditions can result in enforcement action

BS 5837:2012 (Trees in relation to design, demolition and construction) specifies that trees to be retained must be protected by robust fencing erected at or beyond the root protection area (RPA). No activities — including material storage, vehicle parking, excavation, ground level changes, or service routing — are permitted within the protected area. These requirements are typically imposed as planning conditions, and breach can result in enforcement action or prosecution.

What documentation must accompany hazardous waste when it is transported from a construction site?

Answer: A hazardous waste consignment note containing the waste producer's details, waste description and European Waste Catalogue (EWC) code, quantity, carrier registration details, and destination facility permit number — consignment notes must be retained for at least 3 years

Under the Hazardous Waste (England and Wales) Regulations 2005, every movement of hazardous waste must be accompanied by a consignment note containing: the producer's details and premises code; a full description of the waste including its EWC code and hazardous properties; the quantity; the registered carrier's details; and the destination facility's details and environmental permit number. Consignment notes must be retained for a minimum of 3 years by all parties.

What is the legal framework for controlling vibration from construction activities that affects neighbouring properties?

Answer: Vibration is controlled under the Environmental Protection Act 1990 (statutory nuisance), BS 5228-2 (Code of practice for noise and vibration control on construction sites), and planning conditions — vibration limits at sensitive receptors must be monitored and complaints investigated

Construction vibration is controlled by: the Environmental Protection Act 1990 (vibration can constitute a statutory nuisance); BS 5228-2:2009+A1:2014 (provides guidance on vibration prediction, measurement, and control); planning conditions (often set vibration limits at sensitive receptors); and the Party Wall etc. Act 1996 (for work affecting adjoining properties). Continuous vibration monitoring at nearby properties is often required, with trigger and stop limits.
