5361- Kilmainhamwood Compost Facility Extension- EIS
• Establishing channels of communication between the Contractor/Developer, Local Authority and
local Residents;
Furthermore, it is envisaged that a variety of practicable noise control measures will be employed.
These may include:
• Selection of plant with low inherent potential for generation of noise and/or vibration;
• Erection of temporary barriers around items such as generators or high duty compressors. For
maximum effectiveness, a barrier should be positioned as close as possible to either the noise
source or receiver. The barrier should be constructed of material with a mass of > 7kg/m2 and
should have no gaps or joints in the barrier material. As a rough guide, the length of a barrier
should be 5 times greater than its height. A shorter barrier should be bent around the noise
source, to ensure no part of the noise source is visible from the receiving location.
• Siting of noisy plant as far away from sensitive properties as permitted by site constraints.
10.4.2 Operational Phase
The design of the site has been laid out so as to minimise noise impact on the surrounding
environment. All major noise producing plant associated with the proposed facility is to be located within
the site buildings and not in the open air.
This design in itself provides significant noise mitigation advantages in that the noise reaching sensitive
receptors and indeed the site boundaries is much curtailed due to horizontal distance separation.
Worst case operational noise levels are predicted to comfortably comply within the EPA Guidance Note
For Noise In Relation To Scheduled Activities which outlines a limit of a free-field LAr, T value of 55dB
by daytime (08:00 – 22:00), at any noise sensitive location and one of 45dB for night operations. As
such, no further mitigation is required for the operational phase of the development.

As per EPA guidance (see Note 1 below), if a tonal component is detected during noise monitoring
following the construction phase, a +5dB(A) penalty is added to the measured equivalent continuous Aweighted
sound pressure level (LAeq) so as to determine the potential receptor response to the
measured noise.
To date, noise monitoring has been undertaken in accordance with EPA guidance and as per the
requirements of the existing EPA waste licence. Results from noise monitoring undertaken to date
(since the existing facility commenced operations in September 2006) have been in compliance with the
EPA waste licence limits.
Should a tone be observed during noise monitoring post installation of the proposed additional fans, this
would incur the 5dB penalty (as outlined above), and would result in an exceedance of the 55dB LAeq
limit during daytime hours. As such if a tone were to be detected during noise monitoring, it would have
to be engineered out to meet day time limits. However it is not expected that this will arise, as there is
