The baseline monitoring study has been carried out during December 1st 2019 – February 29th 2020 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 semi–mechanized methods which involves Jack Hammer drilling and blasting, excavation, loading and transportation. AERMOD - Model AERMOD was used for prediction of impact of PM10 during conditions i) Consultant: Aadhi Boomi Mining & Enviro Tech (P) Ltd, Salem, Tamil Nadu DRAFT ENVIRONMENTAL IMPACT ASSESSMENT REPORT. Proponent: Thiru. Tvl. Srinivasa & Co, Rough Stone Quarry, Krishnagiri District Loading/unloading and transportation of Rough stone by trucks on Haul roads ii) Drilling iii) 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 and scenario 2 i.e. Drilling was 82/m3 and 88 µg/m3 respectively occurred at the project site after superposition of base-line value 59 µg/m3 over the incremental GLC 23 µg/m3and 29 µg/m3 respectively due to combined impact of loading, unloading, and transportation over the haul road and due to drilling. Total predicted 24-h maximum GLC of PM10 at project site due to blasting was 68 after superposition of base- line value 59µg/m3 over the incremental GLC 9 µg/m3 due to blasting. Meteorological data under worst case scenario providing 24-h maximum average GLC was discussed above and Easterly were dominant. 1.4.2 Noise Environment Noise pollution poses a major health risk to the quarry workers. The sources of noise in the existing open cast quarrying project observed include Drilling, Blasting, Loading, Operation of HEMM and Vehicular Movements.
