Glossary of Terms

‘A’ Weighting

The human ear does not respond uniformly to different frequencies. The ‘A’ weighting is commonly used to simulate the frequency responses of the human ear.

Appropriate Assessment

An assessment of likely impacts associated with a development on a European Protected Site. An Appropriate Assessment is required by law under Regulation 48 of the Habitats Regulations (1994), implementing Article 6(3) of the Habitats Directive (92/43/EEC).

Attenuation

Reduction in intensity.

Baseline

The existing conditions which form the basis or start point of the environmental assessment.

Best Practicable Means

A feasible approach having due regard for means/resources/conditions. Defined in the Control of Pollution Act 1974 and Environmental Protection Act 1990 as measures which are ‘reasonably practicable having regard among other things to local conditions and circumstances, to the current state of technical knowledge and to financial implications’.

Bill

For the purposes of this CoCP references to the Bill are references to the Forth Crossing Bill.

Biodiversity

Biological diversity or species richness of living organisms present in representative communities and populations.

Blasting works

Construction activities involving use of explosives.

Bund

An embankment, wall or dam that can be used to reduce noise effects, provide screening or alternatively when built around an oil tank to contain the contents in the event of spillage.

CDM Co-ordinator

The person appointed under Regulation 14(1) of the Construction (Design and Management) Regulations 2007 to perform the duties specified in Regulations 20 and 21 of the 2007 Regulation.

Cetacean

Refers to a group of marine mammals that includes whales, dolphins and porpoises.

Competent Authority

In relation to Appropriate Assessments has the same meaning as in the Conservation (Natural Habitats &c) Regulations 1994 and for the Forth Replacement Crossing is the Scottish Ministers.

Construction Phase Health and Safety Plan

A strategic tool for safeguarding health and safety on a construction site prepared in accordance with the Construction (Design & Management) Regulations 2007.

Contractor

The organisation(s) directly engaged by the Employer (the Scottish Ministers) for the construction of the Project.

Crichel Down Rules

Non-statutory guidance covering the disposal of surplus government owned land.

Culvert

A metal, wooden, plastic, or concrete conduit through which surface water can flow under or across roads.

dBht

A measurement of sound that provides a metric for estimating the behavioural effects of noise on marine species.

Decibel (dB)

The range of audible sound pressures is approximately 0.00002Pa to 200Pa. Using decibel notation presents this range in a more manageable form.

A decibel is not an absolute unit of measurement but is a logarithmic ratio of the variation in pressure. It should be noted that because the decibel scale is a logarithmic ratio, the arithmetic sum of more than one decibel does not equate to the corresponding noise level. For example, the combined noise level generated by adding two equal noise levels together is approximately 3dB higher than the individual noise levels ie 50dB + 50dB = 53dB.

Effect

The result of change or changes on specific environmental resources or receptors.

Emergency services

The police, fire, ambulance and coastguard services.

Employer’s Representative

The person named by the Employer (the Scottish Ministers) in the contract who acts on behalf of the Employer.

Energy Saving Trust

An organisation which provides energy saving advice.

Environmental Impact Assessment

The process by which information about the environmental effects of a project is evaluated and mitigation measures are identified.

Environmental Management Plan

Document which describes the processes to be followed to ensure compliance with environmental legislation and policy and minimise harm to the environment.

Environmental Management System
