(IV). Proposed Terms of Reference for EIA studies

Scope of Work of EIA

The model terms of conditions published by MoEF&CC in April 2015 shall be strictly

followed. Additional TOR's if any shall be followed.

“...The EIA shall cover the following:

Description of the proposed project:The first task:” Description of the proposed project” forms a vital component of the EnvironmentalImpact Assessment (EIA) as it provides the basis for evaluating the likely causes of EnvironmentalImpacts. It is essential that the granite quarrying activity shall be clearly determined as far aspossible at this stage.

Existing Environment and Baseline Conditions:The baseline assessment will be carried out to identify potentially sensitive and critical areas thatmay be affected by the project in an area of 10 km surrounding the project location. The criticaland sensitive targets shall be plotted on land use map of project impact area.The existing environment and baseline conditions should be established from:-Analysis of existing information published and secondary data.-Consultation with relevant statutory authorities, andField visits for supplementation of missing gaps.

The key subject areas which the EIA shall address include Ecology and Nature conservation, Airquality, surface and water quality in project impact area, soil quality, cultural heritage, landscape,land use, noise quality, etc. Natural habitats like national parks, wildlife reserves, sanctuaries,sacred grove, protected areas, forests, wetlands, major rivers and waterways if any, shall also beidentified and marked.

Assessment of Environmental Impacts:Based upon the results from the review of existing information, field visits, site data collection andconsultation, for each component of environment (physical, biological and socio economic) thepositive, negative, direct and indirect, temporary and permanent impacts will be evaluated alongwith an indication of the degree of impact, i.e., whether the impact is significant, moderate, minoror negligible. The degree of impact shall also be quantified by using state of the art air qualityimpact prediction models based on ISCST3 algorithms.

i. Present Status

There are 3pits in the QL area. Working operation takes place in this pits area during the

past seven years. The pit-1 dimensions are length of 50m and width of 10m with a depth of

1m. The pit-2 dimensions are length of 48m and width of 25m with a depth of 12m. The pit-

3 dimensions are length of 5m and width of 10m with a depth of 1m. The marketable blocks

recovered from the pit during QL period. The applied area does not contain any forest

cover. The area does not consist any wild life. The marketable blocks recovered from the pit

are 1606.34 m3 during 2005-13.

B) Geological Reserves

Based on the exposure of the rock, the reserves of the area have been estimated by the

following parameters. We have taken 12m as proved zone and 3m as probable and possible

zones. In this area the recovery factor is taken only 10% as there are joints and cracks in the

black granites. The QL area is having scattered boulders is presented in table A-2.

Total mineable reserves of black granite in QL area = 33020-1606=31424m3

Total mineable waste available in QL area = 282816m3

C) Mineable reserves and life of the mine

The total quantity of mineable reserves is considered as marketable reserves. In this way a total

mineable reserves of 31424m3 are available in this QL area. The production is proposed to

obtain 500m3 per year. At this rate of production, the expected life of the mine is calculated as

below.

Life of the quarry: Mineable Reserves/ Annual production = 31424/500 = 63 years.

D) Quarrying Method

Open cast method of mining to be carried out in this mine by manually and semi

mechanization by using compressor operated jack hammer drills, excavators and using

dumper etc. Transportation will be made by trucks to dispatching points. Hydraulic

excavator and compressor operated jack hammers to be used for cutting the rock. Close

spaced drilling of 0.2m will be adopted along a straight line and charged with low explosives

to avoid feather cracks. Proponent has been decided to undertake semi mechanized mining

operations; the following mentioned mine machinery will be deployed.

I. Excavator – OneII. 50 CFM – Air Compressor-one

III. Jack hammers – 3 unitsIV. 18 tonnes tippers – 2 no’sV. Minor Tools: Chisels, Crowbars, pick of axes spades and hammers of different sizes.

Year wise Development and production for balance four years

There is a vertical and free face is available on central portion of the QL area. So the central

portion of the QL area is selected to work for next five years production. It is envisaged to

produce 500m3 of salable granite blocks in each year. To raise this target production about

2500 m3 of rock mass has to be mined. Most of this area is covered by the sheet rock from

top to bottom. Year wise quarry development schedule is described below and year wise

production and waste generation details are presented in table A-3.

Drilling and Blasting

Drilling and blasting plays vital role in determining the size and shape of rough blocks.

Drilling pattern is important in developing a working face and also preparing the rough

blocks suitable for their use in appropriate processing units. Even though, there are no

important places in and around the area, blasting will be carried with all precautionally

measures.

1. Drilling Parameters

i. Drill holes diameter: 74/ppm

ii. Depth and inclination of the blast holes. 3m in case of separation primary blocks

depending on the block size. Then the drill-hole will be vertical.

iii. Spacing and burden : 1.5 x 3m

iv. Stemming and charging of the blast hole. The blast hole will be charged with 100

grams of explosives and filled with clan pills subsequently; the shot hole will be

stemmed.

v. Explosive type (1) slurry based explosives or gun powder.

Broad Blasting parameter

Drill hole patterns for primary and secondary smooth blasting. Uniform single line,

equidistant holes (line drilling) will be deployed for separation of blocks from mother rock.

In the case of sheet rock the primary drilling will be in the form of equidistant vertical holes

to take out blocks of Gang Saw.
