To date there has not been any adverse noise impact associated with the operation of the New Turkeylands Quarry and as landfill operations will potentially produce less noise and vibration it is considered that noise will not be a significant issue at the site.
The level of noise that arises from a development site will depend on a number of factors. These include:
ground absorption;
Taking the above into consideration it is noted that there are no nearby sensitive locations. The operational land and buildings of Ronaldsway Airport cover approximately 225ha to the south west of the quarry. The eastern edge of the main east-west runway terminates 300m south west of the site. There are significant noise impacts associated with the airport.
In this instance the distance between the noise source and the receiver and the presence of screening effects due to the barrier of the quarry faces and additional ground absorption shall mitigate any potential noise impacts from the site.
The site operations are located at a distance of 700m minimum from the nearest residential property. In addition the site operations i.e. tipping spreading and pumping, shall be below ground level for the majority of the life of the site. Traffic movements shall be from the Balthane Road into the quarry void, therefore there shall be no additional impacts to those currently experienced at the Old Turkeyland site.
The following control measures will be taken to minimise noise nuisance:
No complaints have been received from the previous operations utilising similar plant or the operations at Old Turkeyland. The proposed noise control measures along with effective day to day site management will ensure that the development is undertaken without significant noise impacts.
There will be no residual impacts from the development in terms of noise climate.
A search was undertaken by Hyder [1998] at the Manx National Heritage Library at the Manx Museum for Historical Ordnance Survey Maps of the site. The following information is reported [Ref:NE70086/D1/1 Nov 1998].
The Ordnance Survey was commissioned by the British Government to survey the island between 1866 and 1871 and maps produced on the following scales: 1:2500, 1:10,560, and 1:63,360. These maps were not revised until the 1950's.
Historical maps dating from 1870-1893 show the Turkeylands Quarry site as fields adjacent to the foreshore. Surrounding land-use is predominantly agricultural, with the hamlet of Ronaldsway and associated dam and mill race located approximately 750m to the south-west.
Archaeological sites within 1km of the quarry include:
Neolithic flints have also been uncovered in drift deposits within 250m of the quarry and an adjacent field, approximately 600m away, is marked as the site of a battle between Magnus and Manx, dated 1250 A.D.
The quarry has been completely excavated and the proposed infilling of the void with inert waste will not impact outside the area already affected by the excavation. No new ground will be broken and it is therefore considered that there will be no negative impact on the archaeological interest of the local area.
It is recognised by C Kniveton Ltd that the proposed development requires to be designed in compliance with current planning and environmental guidelines. The site is located within an agricultural context and proximity of individual residential properties is not an issue, however measures have been devised to mitigate against any potential intrusion resulting from the proposal.
The method of working has been designed on engineering principles that will enable both safe working for site personnel and members of the public.
The Civil Aviation Authority are keen to have the quarry restored at the earliest.
A development of this nature cannot be designed to have "no adverse environmental impacts", however mitigation measures can negate many of these, lower the magnitude of others and reduce the probability of significant impacts occurring.
Following the implementation of the management measures described in the Working Plan [Annexe A], the proposals will have no significant impacts.
An overall benefit has been identified with regard to general public safety, landscape, ecology, agriculture, hydrology and civil aviation.
