Executive Summary

E.1 INTRODUCTION The mining lease of Undari Limestone Mine is located at Survey No. 49/P, Village: Undari, Taluka: Gir-Gadhada, Dist. Gir-Somnath. The area of Lease is 4.0 ha. The lease was granted by Govt. of Gujarat in favor of Shri Dhirajlal Panchanbhai Vanchhani vide order no. MCR-1580 (S-112)- 4886-CHH, dated 28.04.2011. The mining lease was executed & registered on 21.06.2011 for a period of 50 years up to 20.06.2061. It is a chemical grade and cement grade limestone mine working since 2012. The plan was approved under Rule 22 of MCR 1960 vide RCOM, IBM, Udaipur vide letter no. 682 (23) (749)/2010 MCCM (N) UDP, dated 11.04.2011. The modified mining plan was approved by IMB vide letter no. 682 (23) (749) /2010 MCCM (N) UDP, dated 21.10.2013. The project is categorized under Category „B‟ - 1 (a) (mining lease area ≤100 hectare) - {Mining of Minerals} as per the EIA Notification, 2006 and amendment thereof. As the lease area is less than 5.0 ha, hence EC was not required at the time of establishment.

E.2 PROJECT DESCRIPTION Mining Method The present & proposed method of mining operation is manual semi- mechanized opencast method. Mining will be done by using hydraulic excavator, jack hammer, rock breaker, manual sizing, loading and transportation of limestone to Soda Ash/Cement plant through dumpers/tippers. No drilling and blasting is used. Life of Mine Available mineable reserves of Limestone is 14,70,322 tonnes and approximately 3,00,000 MT of limestone will be produced every year hence the life of mine is 6 years based on present available reserves. It may vary depending upon the mining activities carried out by lessee. At the end of life of mine, ultimate depth of the pit will be 28-26 mRL. No top soil will be generated. There will be no overburden or mineral reject in the lease hence backfilling is not possible. At the end of mine life, when pit will be reached ultimate depth and devoid of limestone,

There are no rare or endangered flora/fauna species found in the study area. There are no National Parks or Wild Life Sanctuaries or Eco-Sensitive Zone within 10 km radius from the ML Boundary. Core zone mainly consists of cactus and other thorny vegetation with some trees also while buffer zone consists of agriculture farm, waste land patches, Machundari River, seasonal water bodies. E.3.7 Socio-Economic Environment The study area of 10 Km radius covers Two Talukas of Gir-Somnath District and 50 villages. The total population of the study area is 132773 and comprises of 23518 households as per 2011 Census data. Out of total population, male population is 66607 and female population is 65176. The total literacy rate of the study area was found to be 59.31%. E.4 ANTICIPATED ENVIRONMENTAL IMPACTS AND MITIGATION MEASURES E.4.1 Topography and Drainage The lease area is almost plain. The entire mining lease area has a gentle downward slope from south east to south west. The highest contour is 54m lies in South-Eastern part of the lease area and lowest contour is 49m lies in southern part of India. The sparse soil cover is found on surface within site. Thus, no area will be disturbed due to mining. No perennial stream or Nallah flows in the mine lease area. Garland drain is provided all along the working pit to prevent the entry of surface run-off in working pit during rainy season. A rainwater drain is

Executive Summary - Undari Limestone Mine (Lease area: 4.0 Ha.) E-7 San Envirotech Pvt. Ltd., Ahmedabad passing through the mining block will be diverted and will be connected towards low-lying area. There is no over burden or mines reject hence difficult to backfilled mine out. Hence mine out are at the end of mine life will be used as water reservoir which helpful to water harvesting/water recharging of surrounding area. E.4.2 Air Environment Anticipated impact The air borne Particulate Matter is the main air pollutant contributed by mining. The major sources of air pollution are:  Mining and transportation activities  Fugitive emission from mine breaker To assess the impact due to these activities on air environment, predictions have been carried out using fugitive dust model. The maximum predicted value PM due to mining activities is about 4.610 µg/m3 at 400 m from source in East Direction. This concentration will be observed within the core zone where mining operations will be carried out and its impact on the surrounding is negligible. Mitigation Measures  Regular sprinkling of the haul roads to minimize the generation of air borne dust.  The vehicles will be kept in well-maintained condition so that emission will be minimized.  Mineral transportation to cement plant will be carried out by covered conveyor system.  Development of greenbelt to reduce the spread of air pollution in surrounding areas.  Regular & periodic maintenance of deployed machineries, to reduce smoke emission.  Mask will be provided to workers. E.4.3 Water Environment Anticipated impact No perennial stream or Nallah flows in the mine lease area. Machhundri River is passing at a distance of 6.05 m, which ultimately flows into Arabian Sea. Surface runoff from the mine lease area flows through rain

Executive Summary - Undari Limestone Mine (Lease area: 4.0 Ha.) E-8 San Envirotech Pvt. Ltd., Ahmedabad cut channels due to slope originating within the mine lease. The maximum working depth during period of mine life will be 22 m to 24 m and ground water is at 45 m – 50 m bgl. There will not be intersection of ground water table due to mining. The water requirement for the project will be 7.0 KLD. About 1.8 KLD of domestic sewage will be generated. It will be disposed in septic tank followed by soak pit. Mitigation Measures  No wastewater will be generated from the mine.  During rainy season, collected water in mining pit will be used for sprinkling and greenbelt to reduce fresh water requirement.  Regular water monitoring will be done. E.4.4 Noise Environment Anticipated impact Noise will be produced due to vehicular movement. The mining activity will not generate any noise as no drilling or blasting or use of heavy

machinery is involved. Mitigation Measures  Proper & regular maintenance of vehicles, machinery will be done.  Provision of effective silencers for mining machinery and transport vehicles.  Mining activities will be carried out in day time only.  Speed of trucks entering or leaving the mine will be limited to moderate speed of 25 kmph to prevent undue noise.  Greenbelt will be developed around the mine lease area.  Provision of earmuffs/ear plugs to workers working in noise prone zones in the mine.  Regular ambient noise level monitoring will be conducted in the mine lease area. E.4.5 Land Environment There is no solid waste generation from the mine. No top soil is generated from the mine. No overburden waste material generation is envisaged during the life of mine.

Executive Summary - Undari Limestone Mine (Lease area: 4.0 Ha.) E-9 San Envirotech Pvt. Ltd., Ahmedabad E.4.6 Socio Economic Environment  Increase in employment opportunities and reduction in migrants to outside for employment.  Increase in secondary employment due to increased business, trade commerce and service sector.  Growth in service sectors.  Improvement in living standard of the area.  Improvement in transport, communication, health and educational services.  No R&R plan is involved. The overall impact on the socio economic environment will be beneficial. E.4.7 Biological Environment There is no forest within the lease area. There are no National Parks or Wild Life Sanctuaries or Eco-sensitive zone within 10 km radius from the ML Boundary. Hence no impact on Biological Environment is anticipated due to mining operation. E.4.8 Occupational Health & Mitigation Measures Occupational safety of the workers will be achieved by the following:  Providing a working environment that is favorable to safety & health.  Educating & provision of training regarding risks & hazards.  Periodical medical examination of all workers.  Control of Dust at source by water sprinkling.  Workers will be provided with appropriate PPEs like nose mask respirator, gloves, helmets, eye protections etc.  Noise will be regularly monitored at site.  Provisions of rest shelter for mine workers with facility of drinking water.  First aid facility at site. Apart from above, lessee will incur an amount of Rs. 0.5 lakhs/year towards the periodical checkup of workers.
