(A) Environment Impact Assessment study: 1. Pollution Potential: Air Emission: Dust Emission during Mining, Transportation & Crushing of the Stones which will be controlled by water sprinkling and development of Greenbelt area. Industrial Water Pollution: Nil. Hazardous Wastes Generation: 0.200 MT / Annum Used Oil generation. 2. Anticipated impact based on project operations on receiving Environment 2.1 Population: Pali village is within 500 meters and Mining area is very small. Therefore, very negligible impact will arise due to air pollution on population. 2.2 Flora and Fauna: No endangered Spp. Or forest within 10 KM radius. Surrounding land is wasteland. No farming in the surrounding. Very negligible impact on flora & fauna. 2.3 Water: 2.3.1 Water Consumption 2.3.2 Wastewater Generation 2.3.3 Rain Water Harvesting 2.3.1 Water Consumption: Fresh water requirement will be 2,000 L/Day for the proposed project. Out of this 500 L/Day will be used for domestic purpose, 500 L/Day for Greenbelt Development purpose and 1,000 L/Day for Dust Control Water Sprinkler. The detail breakup of the water consumption is given hereunder in Table: Table : Break up for fresh Water Consumption Purpose Water Consumption Sr.No. Quantity L/Day 1. Domestic 500 2. Green Belt Development 500

3. Water Sprinkler 1,000 Total (1+2+3) 2,000 Water Source: Domestic : Borewell. 2.3.2 Waste water generation: The total wastewater generation will be 500 L/Day from the proposed project. Details of the same are provided hereunder in Table: Table: Break up waste Water generation Purpose Water Consumption Sr.No Quantity L/Day 1. Domestic 500 2. Green Belt Development 500 3. APCM (Water Sprinkler) 1000 Total (1+2+3) 2000 * Disposal to soak pit through septic tank. Sprinkled water will be evaporated in atmosphere in short time and it contains same soil dust of the existing land. Therefore, it is not polluted water. Water Balance Diagram (All figures are in L/Day) Water 2,000 Evaporation Loss 1.000 Domestic 500 Greenbelt Development 500 APCM 1,000 To Soak Pit (500) 2

2.3.3 Rain Water Harvesting : 2.4 Air: As the water is the basic natural resources and towards the step to resource conservation, rain water harvesting system is integrated in the project.

No other electric circuit should be allowed in that area or it will be de-energized. 12

6. Minimum safe distance will be maintained from Radio, TV, Radar transmitters to avoid detonation of cap. 7. The surplus explosives/detonators are returned to the magazines. 8. The Warning and All clear signals will be established and made known to all concern. Trained people are posted at all approaches with red flags to stop all traffic and by passers. 9. The blasting expert then sound a warning siren to drive all people from the danger area and not to allow anybody to enter in the blasting area. After being satisfied with the readiness of blasting, the blasting expert will fire the shots by closing the switch of the exploder. 10. After dispersion of gases and dusts, the expert will return to the area and check for any misfire. 11. Misfire cab be minimized by using good quality explosives, testing each electric cap with blasting galvanometer before loading or by testing the complete circuit before firing 12. Blasting record will be maintained. Date and time of blast, number of holes, amount of charge per hole, firing pattern and sequence will be recorded. 3.7.7 Haulage (pulling and shifting): 1. Material after blasting is carried out mechanically, 2. Workers will not be transported along with the material, 3. Speedy removal of derbies, refuse and trash 4.

Training Be alert and share information; know the blasting time, blast area and clearing procedure and do not enter the blast area until an all-clear signal is sounded 3.7.9 Good Housekeeping : The term good Housekeeping is often loosely understood as simple floor cleaning or broom stick operation. But it has even wider meaning including up keeping of all industrial activities in orderly manner to minimize the accidents due to improper 13

planning, placement, arrangement, handling, etc. everywhere in industrial premises. Place for everything and everything on proper place. So, Good housekeeping at quarry site will greatly reduce unsafe conditions and so risk of accidents. 14
