Environmental guidance for your business in Northern Ireland & Scotland
Demolition works that occur close to, or in, the water environment, such as hydro-demolition works have potential to cause water pollution. Effluent produced as a result of the demolition works must not be discharged into the water environment without authorisation from your environmental regulator. This would be classed as a discharge of effluent either to water or to groundwater.
You would have to treat the effluent prior to discharge.
Alternatively effluents can be sent off-site to a licensed facility for treatment and/or disposal, in accordance with the Duty of Care for Waste.
If you pollute a watercourse, water body or groundwater, your environmental regulator can serve you with an 'anti pollution works notice'. This requires you to clean up the pollution that you have caused. This could lead to construction work on site being halted for a time.
You should place on drip trays static plant and equipment that operates near the water environment or drains. This will help to prevent water pollution from oil spills and leaks.
In Scotland any static plant or machinery used within 10m of any:
must be placed on a suitable drip tray with a capacity equal to 110% of the capacity of the fuel tank that supplies the equipment. You must make sure that the equipment you use does not leak oil.
Empty drip trays regularly to make sure that they can contain any spills.
If your works require the removal of vegetation close to or on a riverbank:
In Northern Ireland , it is an offence to deposit any polluting matter, or anything which could impede the water's proper flow, into a watercourse. You should consult the Northern Ireland Environment Agency (NIEA) and the Rivers Agency if your work is near a watercourse.
In Scotland, it is an offence to allow any polluting matter or solid waste matter to enter a watercourse.
Invasive weeds such as japanese knotweed and giant hogweed are commonly found on riverbanks. If these species are present in or around your working area, you will need to take additional precautions to avoid their spread and to protect the workforce.
In Northern Ireland you must have consent from the Rivers Agency before you place structures in any waterway that could affect its drainage. Contact your local Rivers Agency office for further information.
In Scotland, if you carry out building and engineering works that could significantly affect the water environment, you must either:
Guidance for Pollution Prevention (GPP) 5 contains guidance on how you can avoid causing pollution during works and maintenance in or near water.
Noise and vibration from heavy machinery and construction activities such as pile driving can disrupt and disturb fish migrations and breeding. Extreme vibration can even kill fish. Noise and vibration can also disturb wildlife such as birds and otters, especially during the breeding season.
Under conservation legislation, including the Habitats Directive and the Environmental Liability Directive, if your activities kill or disturb protected species, or damage biodiversity you could be committing an offence.
If you are working close to a stream or river you should:
If you have any concerns about noise and vibration and its impact on wildlife, contact your environmental regulator.
