PRELIMINARY ENVIRONMENTAL IMPACT ASSESSMENT

Abstract: Along the rapid growth of human needs in many sectors, a significant decrease in the availability and viability of the natural resources is always faced. The high volume production is always associated by considerable amount of waste materials that may adversely impacts the surrounding environment. One of the major waste generating industries is the marble production industry, by which ornamental stone manufacture acquires special mitigation process and environmental assessment to minimize the negative environmental impacts that may generate. Efforts on bypassing such dilemma were intensified looking for new regulations and legislations to minimize and reuse the generated waste. This study addressed the possible environmental impacts that might generate from marble stone production in Sandkotra (Rajasthan). Preliminary environmental impact assessment was conducted at Sandkotra mining area in Jaipur district, Rajasthan. The assessment included testing of major chemical and physical environmental resources, products and byproducts generated from the mines. From the results it was observed that noise levels (45.5-52.2 dB(A) in the core zone and 47.9-68.8 dB(A) along the roads) in the mining area were within permissible limits of Indian standards for ambient noise levels, but the noise level near some machines commonly used at site was more than the standard, which require special attention. Air quality results showed that the concentration of SPM, SO2 and NOx were within the permissible limits of CPCB for industrial and mixed use and also for residential and rural environment. Chemical analysis of mine effluent indicated that except few parameters, all other parameters were within permissible limits and the quality of water from villages is in compliance with BIS : 10500 standards. In terms of land resources, marble waste products, may form a source of contamination through the unsuitable solid waste disposal strategies adopted by the mine owners. From past studies it has been found that the marble waste (marble powder, small pieces of marble & marble slurry) can be used in concrete, manufacturing of tiles, bricks etc. and also due to the high percentage of limestone in it, it can be used as a substitute for limestone in many industries.
