Earsham Quarry, Norfolk – Noise & Air Quality Assessments

Earsham Quarry Extensions

Planning permission was granted in September 2020 for three extension areas to Earsham Quarry totalling some 32 hectares.

Independent Environmental Consultancy (IEC) carried out Noise & Air Quality Assessments as part of the Environmental Statement (ES). Monitoring was carried out at a number of locations to establish baseline conditions for noise and dust during 2019.

Noise Surveys

Noise predictions using CadnaA (Computer Aided Noise Abatement) modelling software were carried out at identified noise-sensitive receptor locations. A series of recommendations were included within a strategy to minimise potential noise emissions from the mineral workings during the lifetime of the proposed scheme. The outcome of the modelling demonstrated national Planning Practice Guidance (PPG) criterion would be met for routine and temporary site operations.

Air Quality Assessments

The Air Quality Assessment was carried out using the Institute of Air Quality Management (IAQM) Guidance on the Assessment of Mineral Dust Impacts for Planning. The significance of potential fugitive dust emission effects was concluded to be not significant, in accordance with the IAQM methodology.  Mitigation measures were detailed within a Dust Management Plan which was described by the Environmental Protection consultee for Norfolk County Council as “comprehensive”.
