LOCATION OF THE PROPOSED PERMIT AREA: The location of the proposed quarry site is located in the river bed of Jiabhorali, which is a perennial river and falls under the jurisdiction of Diplonga Range of Sonitpur East Division, Biswanath Chariali, District: Biswanath, Assam The location map of the proposed Permit area is shown in the Fig. 1. The Jiyabhorali, one of the major tributaries of the river Brahmaputra, flows down from the lower Himalayas in Arunachal Pradesh in the northeastern India and runs through the middle of of Assam for about 66 km before meeting the Brahmaputra at . The river known as Kameng in Arunachal Pradesh flows orthogonal to the Himalayan thrust pattern and deflects along the Tipi Thrust in north and foothills fault in the south respectively, before debouching into the foreland at Bhalukpung where it takes the name of Jiyabhorali. The region has extensive tea-plantations and paddy fields. The northern portion is made up of Reserve Forests and sparsely populated forest- villages. The region abounds in biodiversity with evergreen and deciduous trees of many types. The proposed site contains sandy earth. The other details of the proposed Permit are as follows: 1. Village : Dekachowk P.O. : Dekachowk Police Station : Jamugurihat District : Biswanath State : Assam 2. Term of the Mining Permit : 2 years 3. Total area : 4.80 Hectares 4.

THE ALLOTED LAND AND THE TYPE OF SANDY EARTH:

The total area proposed for grant of Mining Permit to Simplex Infrastructure Limited for collection of sandy earth is 4.80 Hectares. The area is a part of the river bed of Jiabhorali river, as described earlier (Fig.2). As per statement furnished by Divisional Forest Officer, Sonitpur East Division, the total area available for mining is 4.80 Hectares. The available mineral of the Permit area i.e. ‘sandy earth’ are to be extracted following the simple open cast quarrying practice as explained in subsequent chapters.

PROPERTIES OF THE SANDY EARTH: The sandy earth available is medium to fine grained.

USE: The minerals so available are suitable for use basically in filling and other construction works.

- 6 -

MINING PLAN M/s Simplex Infrastructure Ltd.

RESERVE: The calculated mineral reserves of the Permit area to be available for extraction are as stated below: The area of the Permit site = 4.80 Hectares = 48000 Sq. M The maximum depth allowed for extraction of the mineral = 3 M So the total reserve of the minerals available would be = 48000 X 3 = 144000 Cu M The above quantity may be termed as ‘Inferred Reserve’ of the mineral and the actual mineral reserve will be less than the inferred reserve as a considerable volume of the minerals will have to be left unmined for preparation of the benches/ steps as per opencast mining practice. This has been explained separately in the later chapters.

MINEABLE RESERVE OF THE MINERALS: Assuming the river bed of the Mining Permit Area to be level area, the reserve of sandy earth available for extraction can be estimated as stated below:- The area of the Mining Permit Site = 4.80 Hectares = 48000 Sq. M Maximum depth allowed for river bed mining = 3M So, the total reserve of the sandy earth would be = 48000 X 3 = 144000 Cu.M For extraction of the sandy earth under the opencast mining method, three numbers of benches each of 1m depth and 1.5M width may be maintained as indicated in Fig. 3. Since the total period of the Mining Permit would be 2 (two) years, the reserve of sandy earth and gravel available for extraction per year would be about (144000/2) = 72000 Cu Metres. Mining Loss being assumed as 10% during the extraction operation would be :- (72000 X 10%) = 7200 Cu.M The mineable reserve of sandy earth per year =(72000 -7200) = 64800 Cu.M

- 7 -

MINING PLAN M/s Simplex Infrastructure Ltd.

So, mineable reserve of sandy earth during the awarded Mining Permit period of 2 years = 64800 X 2 = 129600 Cu.M Extraction/ collection work of river sandy earth is normally carried out for 10 months in a year. The work remains suspended for the rest four months in a year due to seasonal monsoon rainfall and other related problems. Considering the number of working days, in a month to be 25 days, the total working days in a year would be = (25 X 10) = 250 days. So the extraction of river sandy earth in a year (i.e. for 250 days) would be about = (64800 / 365) X 250 = 44384 Cu M. The aforesaid quantity of 44384 Cu.M of sandy earth per year has been estimated considering extraction up to the maximum permissible depth of 3 metres in the river bed from the unmined top surface. But the sandy earth of the desired quality for the useful purposes may not be available in the Jiabhorali River bed up to 3 metres depth. Hence, the mineable reserve of sandy earth and gravel available for extraction per year up to different depths is assessed as shown below. Depth Mineable reserve of sandy earth available per year (Approx) 3 metres 44384 Cu. M 2 metres 29590 Cu. M 1 metre 14795 Cu. M 0.5 metre 7398 Cu. M However, the Competent Authority may prescribe the quantity of sandy earth to be extracted by the Mining Permit Holder as per the terms and conditions of the Permit taking into account the impact on the ecology and environment of the surrounding areas. However, the quantity of sandy earth allotted for extraction under the Mining Permit will be within the mineable reserve of sandy earth available per year as depicted above.

MINING:

In order to ensure mineral conservation, systematic mining and protection of environment, the Assam Minor Mineral Concession Rules (AMMCR), 1994 has been replaced by AMMCR, 2013 and it has been made mandatory to prepare Mining Plan and progressive Mine Closure Plan for grant of any mineral concessions like “Mining Lease”, “Mining Contract” or “Mining Permit” in respect of minor minerals for systematic and scientific development of all mines, quarries as well as river bed mining. In the present case, it is proposed to allow the Mining Permit holder to extract sandy earth from the river bed of Jiabhorali, which is a perennial river. The Mining Permit site on the river bed contains mainly sandy earth to be extracted as per the terms of the Permit. This may be termed as River Bed Mining. The Mining Permit area being a compact deposit of river sandy earth and to extract the same from this deposit, manual opencast method of mining is suggested. The holder will adopt the following: 1. The entire boundary of the Mining Permit area will be marked with boundary lines and pillars in all the corner points. The boundary pillars are to be numbered and marked with GPS coordinate there on. Extraction of sandy earth is to be carried out with a bench height of 0.5 metre to 1.0 metre for the whole area. Use of explosives for mining is not required. 2. The sandy earth extracted and stacked by the Mining Permit Holder will not exceed twice the average monthly production. 3. The extraction of sandy earth will be restricted within the central 3/4th width of the river. The average mineable width of the Permit area is to be kept at 1059 metres out of the average width of the river being 1412 metres as per rule 39(iv) of AMMCR, 2013. (Fig.5)

MINING PLAN M/s Simplex Infrastructure Ltd.

PRODUCTION OF SANDY EARTH: The Mining Permit proposed to be granted to the applicant Simplex Infrastructure Limited in the river bed of Jiabhorali is for extraction of sandy earth manually. The Jiabhorali river is a perennial river and hence, during the monsoon rains, considerable amount of transported mineral (sandy earth) is transported by the flow of river water. As per the Letter of Intent No. FSET/ B/ Permit/ 2019/ 2782, dtd. 17.05.2019, of the Divisional Forest Officer of Sonitpur East Division, Biswanath Chariali, the total Mining Permit period is two years. As has been estimated and stated in the chapter at on Mineable Reserve of mineral, the total quantity of the sandy earth available for extraction in a year upto a depth of 3 metres would be = 44384 Cu M. Considering total working days in a year for transportation of the sandy earth as 250 days, maximum daily transportation of the minerals would be = 44384 / 250 = 178 Cu M Considering the carrying capacity of the Trucks/Dumpers to be deployed is of 5 Cu M average, the total trips to be made by the Trucks/Dumpers would be = 178/5 = 35 to 36 per day. The sandy earth will be transported from the Stacks to various government, semi-government and private consumers mainly for construction purposes. The quantity of sandy earth stated above is an estimated quantity that may be available for extraction considering the extent of the area of the Mining Permit Site. However, the competent authority shall decide and fix the quantity of sandy earth to be lifted by the Mining Permit Holder as per terms and conditions of the Mining Permit with due emphasis on the impact on environment and ecology of the surrounding areas.

MINING PLAN M/s Simplex Infrastructure Ltd.

PROGRESSIVE MINE CLOSURE PLAN:

The “Assam Minor Mineral Concession Rules 2013” published in March 2013, has made it mandatory to incorporate “Progressive Mine Closure Plan” in the Mining Plan vide Rule 52(5)(VIII) of the said rules. Such a Mine Closure Plan is useful in case of opencast mines or quarries only wherein the question of phased restoration, reclamation and rehabilitation of land affected by mining operation is involved. The Jiabhorali River is a perennial river and hence, during the monsoon rains, considerable amount of transported mineral (sandy earth) is transported by the flow of river water. The instant case of Mining Permit is a river bed mining for sandy earth only. Sandy earth is to be extracted from the river bed in a systematic manner as described in earlier chapters. The void created by extraction of sandy earth from the river bed would gradually be filled up with the sandy earth carried by the flow of river channel and would be replenished every year. This filling up process is slow in the dry season and rapid during the rainy season. The restoration of the river bed to its original position through natural process is more congenial to the aqua-marine environment than the reclamation with earth/ silt etc. brought from elsewhere. Since the river bed will regain its original position through natural process after closure of the mine on expiry of the Permit Period, a progressive mine closure plan would not be necessary in this case.

CONCLUSION:

The proposed Mining Permit for river sandy earth covering an area of 4.80 Hectares allotted to Simplex Infrastructure Limited, with their office at Betkuchi, P.O. Sawkuchi, Lakhara P.S. Garchuk Dist. Kamrup (M), is meant for extraction/ collection of sandy earth from the bed of Jiabhorali River within a period of two years. The river sandy earth accumulated during rainy season by the flowing water is to be collected manually during the dry season when water level recedes. River bed mining process is not like other open cast mining operations of minerals, rocks etc. The following conclusions are drawn: 1. The Mining Permit involves collection of sandy earth from Jiabhorali River bed within a period of two years at the rate of 50,000 Cu. M per year for sandy earth. 2. The river bed mining does not necessitate any cutting of trees, drilling and blasting etc. As such chances of air pollution would be negligible. 3. Sandy earth collection at limited quantity through manual means will have least impact on the water quality of the river. 4. Adverse impact on the surrounding environment due to operation of the Mining Permit will be negligible. 5. The extraction of sandy earth from the river bed will not go beyond the depth of 3.0 metres from the unmined top level of the river bed at any point in no case as stipulated under the provision of rule 39(iii) of AMMCR, 2013. 6. The sandy earth collection from the river bed would be utilized for various construction and filling purposes. 7. The operation of the Mining Contract would help in upliftment of socio- economic scenario of the locality.
