3 1.0 INTRODUCTION Gravel & Rough Stone Quarry. Extent of Ha is located in Sy. No. 211 (Carved out of Sy.No.1) of Tarluwada Village, Anandapuram Mandal, Visakhapatnam District, Andhra Pradesh. Brief Description of the Nature of the Project. Project is Gravel & Rough Stone mine located in an area of Ha. It is proposed to produce Gravel Cu.m/Annum & Rough Stone of 1,05,000 Cu.m/annum by means of opencast other than fully mechanized mining method. The ROM will be sorted into different sizes by feeding it to the crusher proposed to be established outside the applied area. The ROM will be loaded into tippers and tractors using JCB backhoe. The cost of the Project is Rs 50/- Lakhs. 2.0 Mining Methodology Open cast semi mechanized method mining method shall be adopted Mining is proposed to be carried out by opencast semi-mechanized method using, Excavator and Tippers. Transportation of mineral will be done by trucks. The loading of Gravel & Rough Stone will be done by excavators Transportation: Stone excavated from the quarry is transported to the crushing unit material through 15 MT capacity trucks/dumpers. During transportation overfilling of trucks and consequent spillage of materials on the roads will be avoided by covering tarpaulin in the loaded trucks. List of Machinery/Equipment Proposed: The nature and quantity of machinery required for excavation and /or blasting of construction stone / rock depends on the production capacity of the quarry. However, the machines used are as follows:

4 LIST OF MACHINERY Sl. No. Type of machine No 1 Excavator 1 2 Tippers 2 3 Water Tankers 1 4 Pick-up/Jeep DESCRIPTION OF ENVIRONMENT The project environmental quality in the vicinity of a quarry lease area identified for proposed mining serves as the baseline status and also for identification of environmental concerns/impacts corresponding to project area. 3.1 Water Regime: No perennial streams are existing in and around the quarry lease area. Ground water in plenty is available 3.2 Flora and Fauna: The subject area is devoid of trees and major vegetative cover no major wild life exists in the area. 3.3 Quality of Air, Water and Ambient Noise Level: The subject area is away from industries and Human settlements. The impact of quarrying is not likely to have any adverse impact on the existing environment. Quarrying even on a small scale causes some environmental impact. Therefore, efforts are necessary to mitigate the environmental impact created. The management is well aware of this aspect and will take all precautions to mitigate the impact. 3.4 Climatic Conditions: The area falls in semi-arid area is falling under semi-arid tropical zone. The area is having dry climate. The temperature recorded in this area is 250C in winter and about 480C summer seasons. The wind direction is SW-NE direction

5 3.5 Human settlements Human settlements within 5 km of the quarry are given below: 3.6 Public buildings Village Population Tarluwada 561 (Source: No public buildings, important places and monuments are seen in and around the quarry lease area; however, the lessee will adopt the safety measures while conducting the quarry operations as per the Regulations of Metalliferrous Mines Regulation 1961 Sanctuaries/ eco-sensitive areas There are no Sanctuaries/ eco-sensitive areas existing within 5 km radius 4.0 IMPACT ASSESSMENT (a) Land Area. The mining lease area is Ha. excavation will progress in next five years Ha and 7.5m barrier zone Ha. The excavated area will be reclaimed by afforestation/converting into water holding tank. (b) Air Quality The project includes various quarrying operations involving development of benches, approach roads, haul roads, drilling, blasting, excavation and transportation

6 These operations generally result in generation of dust and thereby pose health hazards. However, adequate control measures will be provided at every stage of operation such as water sprinkling at loading and unloading point and on haul roads before transportation to reduce the fugitive dust emissions. Heavy Earth Moving Machinery like excavator, dumpers, dozer and other transport vehicles will emit gaseous pollutants mainly CO and NOx. The generation of dust is anticipated from various quarry activities i.e. drilling, blasting, loading, haulage, unloading, and other activities related to quarry. The increment in the fugitive emissions will be due to material handling and transportation activity. These will be restricted to the lease area only by adopting water sprinkling, which will be practiced at the quarry site to control air pollution load. When the mines are under closure, the following is the ambient air quality. AAQ Monitoring Station No. Locations PM10 VALUES (ug/m 3 ) PM2.5 SO2 NOX 1. Mine Site Tarluwada Ambient air quality standards promulgated by National Ambient Air Quality applicable to the subject project are given below Pollutant Sulphur Dioxide (SO2), µg/m 3 NAAQ Standards Time Weighted Average Annual* 24 hours** Concentration in Ambient Air Industrial, Residential, Rural and Other Area Nitrogen Dioxide (NO2), Annual* 40

7 µg/m 3 24 hours** 80 Particulate Matter (size less than 10 µm) or PM10 µg/m 3 Particulate Matter (size less than 2.5 µm) or PM2.5 µg/m 3 Annual* 24 hours** Annual* 24 hours** Dust levels will be higher within the active operational areas (quarry area) due to blasting and transportation. However, in the buffer zone it is not likely to be affected by dust problems, when proper dust suppression measures are taken. Air Quality Management The following measures will be adopted to mitigate air pollution generated due to the quarry activities: water sprinkling while drilling Rock breaker will be used for breaking over size boulders in order to reduce dust and noise generation. Water spray on haulage roads & proper maintenance of haul roads will be done. Development of green belt around lease boundary, roads and other places will be carried out to control the air pollution. Personal Protective Equipment like dust mask will be provided to all employees working in the dusty areas. Proper maintenance of vehicles will be done to limit gaseous emissions. (c) Water Quality Water consumption in the mine is estimated to be about 40 m 3 /day as detailed below in table. Source of water is from bore well/local purchase.

8 WATER BALANCE (m 3 /day) Requirement Loss Wastewater Dust suppression Greenbelt Drinking Water Total Surface Water There is no perennial surface water source in the quarry lease area. Ground water is the source for the nearby habitation also. Stone is non-toxic in nature. There will be no outside discharge of liquid effluent from the quarry site. Ground Water Ground water pollution can take place only if the quarry rejects contain toxic substances, which get leached by the precipitation water and percolate to the ground water table thus polluting it. Any nearby wells or other sources of water can be rendered unfit for drinking and even for industrial use. This is not the case with this deposit as the stone or topsoil does not contain any harmful ingredients. Moreover, stone constitutes of fairly inert and chemically non- reactive ingredients. The general ground level in the quarry area is 160mRL. The water table lies at 20 m from the general ground level. The quarry workings will not intersect ground water table. Water Pollution Control Measures The following measures will be implemented to prevent water pollution (if any) from the quarry: No wastewater will be generated during quarry operation Garland drains all along the downstream boundary of the

9 pit. Rainwater falling in the quarry pit will flow based on the slope into the garland drain provided with sedimentation pits. (d) Noise Levels Noise generation is from operations at quarry development, excavation and transportation of stone. High noise levels will be confined to work zone areas only. Noise levels get diffused rapidly with distance. Noise impact is mainly restricted to the work zone areas. Hence, the noise levels impact due to the quarry operations on community is insignificant. Noise Control Measures The following control measures will be adopted to keep the ambient noise levels well below the limits: Controlled blasting with proper spacing, burden, stemming and optimum charge/delay will be maintained. The blasting will be carried out during less human activity timings i.e. during lunch interval or during change of shifts. Proper maintenance, oiling and greasing of machines at regular intervals will be done. Green Belt and Plantation will be developed wherever possible f. Acid Mine drainage There is no possibility of acid mine drainage g. Surface Subsidence The mining operations are by opencast method and no surface subsidence will be there

10 h. Socio economics The main occupation of villagers is agriculture. The operations of mining activity in this area improved the socio-economic status of the local people by creation of employment i. Historical Monuments There are no Historical Monuments within 10 km radius of the quarry lease area 4.1 Post Project Monitoring Pollution monitoring program includes periodic analysis of air, ground water, soil and water samples. Ground water and soil samples at representative locations within and nearby the project site shall be periodically analyzed to detect contamination if any. In the event of any contamination, concerned authorities shall be notified immediately and appropriate corrective action in consultation with an approved consultant shall be initiated. 4.2 Monitoring Strategy The monitoring of various environmental parameters is necessary and is a part and parcel of the environmental protection measures. Monitoring is as important as that of control of pollution since the efficiency of control measures can only be determined by monitoring. A well-defined environmental monitoring program would be employed with trained and qualified staff to monitor the ambient air to check whether the quality of effluents is maintained within the permissible limits. A comprehensive monitoring program is suggested underneath. Environmental attributes should be monitored as given below: Air pollution and meteorological aspects. Water and waste water quality. Noise levels. Soil characteristics.

11 Ecological preservation and up-gradation. Locations and frequency of monitoring will be as per the guidelines of Andhra Pradesh pollution control board and MOEF/SEIAA. 4.3 Ambient Air Monitoring As per MOEF& CC there is a need to identify 3 ambient air stations at 120 angle keeping the main source in the center. The ground level concentrations of suspended particulate, sulphur dioxide and nitrogen oxides in the ambient air outside the project boundaries and in the adjoining villages will be monitored at regular intervals. Any deviation from predicted/'expected values will be investigated and necessary action will be taken. 4.4 Noise Monitoring Noise levels in the workspace environment will be monitored periodically. If any deviation is observed necessary corrective measures will be taken. Monitoring noise levels is essential to assess the efficacy of maintenance of schedules undertaken to reduce noise levels and noise protection measures. A good quality sound pressure level meter is essential for this purpose. This work can be handled by plant authorities themselves or by hiring services. Noise surveillance is for the benefit of the workers well- being and to keep track of machine wear. 4.5 Monitoring of Water Quality Ground water near the project site will be routinely tested for its quality. No contamination of ground water and surface water is expected. However these waters will be periodically tested for any change of water quality. The effluents coming out of the process should be monitored regularly. Ground water is recommended to be monitored in at least two villages in the direction of ground water flow to keep surveillance on the ground water quality.

12 4.6 Reclamation Reclamation is in terms of vegetation after the rock is consumed and also as conversion into water reservoir, where possible. 4.7 Site Services Following facilities will be provided for the smooth working of the quarries:- Quarry office First aid room Store facility Toilet facility Drinking water facilities Rest shelters
