8 Dust and Air Pollution

8.1 Dust and Other Air Pollution

(a) The Contractor shall take all necessary measures to avoid creating a dust nuisance during construction and demolition works.

(b) Measurers to prevent dust shall include the following:

(i) The provision of easily-cleaned hard standings for vehicles
(ii) The enclosure of material stockpiles at all times and damping down of dusty materials using water sprays during dry weather.
(iii) The hard surfacing of heavily-used areas which will be kept clean by regular brushing and water spraying.
(iv) Control of dust released from cutting or grinding of materials on site. Any mobile crushing plant that is used during construction must be appropriately licensed and sited so as to minimise dust annoyance to any persons who may be liable to be affected by emissions. The Scottish Environment Protection Agency (SEPA) shall be notified in advance of any mobile crushing plant being brought onto site. All reasonable measures will be taken to minimise on-site cutting.
(v) The complete sheeting of all vehicles carrying spoil and other dusty materials.
(vi) Watering of unpaved surfaces and roads.
(vii) A limit on vehicle speeds on unpaved surfaces of 20 kph.

(c) Where dust generating works (e.g. excavation, demolition) are undertaken close to buildings such that there is a potential for soiling of windows and ledges with dust the contractors shall clean those windows and ledges as necessary – and at least weekly - during periods of dust generating work and on completion of works the contractor shall take precautions to prevent damage occurring as a consequence of cleaning works..

(d) The Contractor shall take precautions to prevent the emission of smoke or fumes from construction vehicles, site plant and stored materials including volatile substances. Vehicles and plant shall be well maintained and measures shall be taken to ensure that engines and motors are not left running for long periods when not directly in use.

(e) The engines of all parked vehicles or vehicles waiting to enter any work area shall be switched off within two minutes of arrival.

(f) Work compounds shall be laid out so that accesses and loading areas are located as far away from sensitive neighbours as practicably possible and so that temporary structures screen noisy areas where practicable.

(g) There shall be no burning of waste on site.
