The baseline monitoring study has been carried out during October 1st, 2019 - December 31st, 2019 to assess the existing environmental scenario in the area. For the purpose of EIA studies, mine lease area was considered as the core zone and area outside the mine lease boundary up to 10km radius from the lease boundary was considered as buffer zone.

The mining operation will be carried out by adopting Manual methods which involves Jack Hammer drilling and blasting, excavation, loading and transportation. AERMOD was used for prediction of impact of PM10 during conditions i) Loading/unloading and transportation of Rough Stone by trucks on Haul roads ii) Blasting by using area source model to predict GLC of PM10 during these conditions. Total predicted 24-h maximum GLC of PM10 at project site for scenario 1 i.e. loading- unloading, transportation& open pit and scenario 2 i.e. Blasting 95/m3 and 73 µg/m3 respectively occurred at the project site after superposition of base-line value 62 µg/m3 6 | Page Consultant: Aadhi Boomi Mining & Enviro Tech (P) Ltd, Salem, Tamil Nadu Proponent: M/s Sree Thiruchendhur Murugan Blue Metals, Rough Stone & Gravel Quarry, Viluppuram District over the incremental GLC 33 µg/m3and 11 µg/m3 respectively due to combined impact of loading, unloading, open pit and transportation over the haul road and due to blasting.
