4.10. Impact due to Transportation of Mined out material on environment The mining in a tehsil shall be carried out along different rivers which for the have been divided into different blocks The collective stretch of the lease area for each river has been sub-divided in to five blocks for ease of operation, supervision, management and safety. The daily production has been envisaged as 8000 metric tonne. The quantity of daily production of mine shall significantly vary reach-wise and block-wise. The maximum production in Tehsil Pali has been envisaged in Somesar river at Busi. At this place about 500 MT daily production is stipulated for the transportation of which 25 tripper/trucks (20T) shall be required. The increased traffic load due to transportation of mineral shall not be concentrated in a particular segment of the road as the material shall be dispatched to different destination and in different directions. The impact due to transportation shall be on carrying capacity of the State Highway/ National Highway and also due to increase in vehicular emissions due to mineral transportation.
4.10.1. Impact on the carrying capacity of SH and NH due to proposed transport activities The bulk of mineral mined out from river Somesar, Khari, Bandi and upto Hemawas Dam shall be transported through SH-67 (Pali – Dessuri - Gomti Nagar). The mined out material from Bandi river d/s of Hemawas dam (from villages Jawariya, Kerla and Muliyawas, Rupawas and others) shall be mostly transported through NH-65 (Pali - Jodhpur). The mined out material from Khardi and Mithri river shall be transported through NH-14. About 1.68 million tonne material / annum (75%) shall be transported through SH-67; 0.34 million tonne / annum (15%) shall be transported through NH-65 and balance 0.22 through NH-14 (10%). The transport plan for movement of trucks is shown in Figure 4.4. The study for carrying capacity has been carried out for these roads by undertaking traffic volume counts at the prominent inter-junction of these roads as per guideline of IRC:9-1972 and IRC:SP 19-2001 and the PCU factors adopted for analysis has been taken as per IRC:64-1990.
Figure 4.1 : Transport Route Map
Classified Volume Count Traffic Survey The traffic survey is essential to realistically and accurately assess the prevailing traffic volumes and travel characteristics by undertaking classified volume count. The objective of traffic volume count survey is to assess the traffic intensity on the most vulnerable section of the road under question. Two – days, 24 hrs., continuous volume counts were manually undertaken during October 2013 at Mandli Khurd on SH-67, CARZI on NH-65 and Pali on NH-14 for capturing the realistic picture of the current volume and composition of traffic motorized i.e. passenger vehicles (two-wheeler, three-wheeler, bicycle, passenger car); utility vehicles (Jeep, Van, Mini Bus, Standard Bus); Goods vehicles – LCV (Freight), MCV (2 axle rigid chasis), MCV (3 axle rigid chasis), MAV and tractor trailer and non-motorized like animal driven cart. The survey work was conducted by engaging educated people familiar with traffic characteristics. Before the start of survey the enumerated engaged were briefed and trained by an expert supervisor about the task. The analysis of traffic counts provides an estimate of average daily traffic (ADT). In order to convert recorded vehicles into a common scale, the passenger car units (PCU) equivalent factor as per IRC:64 -1990 has been adopted. The Table 4.7 reveals that the total ADT at Mandli Khurd on SH-67 were 3867 in terms of number which translates into 4241 in terms of PCU. The Table 4.8 reveals that the total ADT at CARZI on NH- 65 were 3601 in terms of number which translates into 5994 in terms of PCU. The Table 4.9 reveals that the total ADT at Pali on NH-14 were 4218 in terms of number which translates into 6243 in terms of PCU. It is thus evident that the number of PCU / hour at Mandli Khurd, CARZI and Pali 177, 250 and 260 respectively.

7.2. Replenishment Studies 7.2.1. Sediment Yield From Watershed The rate of gross or absolute silt production (erosion) in the watershed and the ability of the stream system to transport the eroded material in a river and then to a reservoir has the direct relation with the quantity of sediment delivered into a reservoir. The rate of gross erosion is dependent upon many physical factors live climatic conditions, nature of soil, slope of the area, topography and the land use. Hydro-physical conditions of the watershed govern the capability of transporting the eroded material. It has been observed that the average rate of sediment production decreases as the size of drainage area increase and the larger watershed the lesser is the variation between the rates. The larger watershed presents more opportunity for deposition of silt during its traverse from the point of production. The watershed with maximum land use class of forest generate very low rate of production unless the forest are degraded or open forest. The cultivated watersheds with unscientific farming produce very high rate of silt production. The total amount of eroded material, which reaches a particular hydraulic control point, is termed as sediment yield. The sediment control of inflow is governed by Character of run-off; Susceptibility of soils; the extent and density of vegetative cover in the area; and The hydraulic efficiency of the drainage system.
The sediment load comprises of bed load as well as suspended load, the former being the eroded material kept in motion in the bottom layers of the flow due to rolling, sliding and hopping, while the latter being the smaller size particles in saltation being thrown in suspension by the upward component of the turbulent velocity of flow. When the tractive force exceeds the frictional resistance between sand particles the latter are set in motion. The resistance to sediment to motion is directly proportional to the diameter of sediments ‘d’ and the specific weight of sediments in water (G-1), where ‘G’ is the specific gravity of sediments. The equation of critical tractive forces is:-
c = 0.078d
where, ‘d’ is in mm and c is in kg/sqm
7.2.2. Estimation of Sedimentation Rate The scientific survey for determination of soil erosion rate from catchment and deposition rate in reservoirs have been frequently and widely conducted in past in India and in other countries. Sedimentation rate on the basis of actual measurement have been arrived for different perennial rivers by stream sampling of sediment load including bed load. Surveys of some of the existing reservoirs was carried out to assess the actual silting experienced by them over
EQMS INDIA PVT. LTD. 1 long period after impoundment. Thus the fundamental method for estimation of sediment is on the basis of actual measurements carried out in the basin.
7.2.2.1 Sedimentation rate on the basis of actual measurement Sediment sampling over a substantially long period is a suitable and logical method of obtaining information of sediment load being carried out by a stream. No sediment load observation have been made in the case of any of the rivers flowing the district/Tehsil as the rivers are seasonal and flow during monsoon alone and that the study period was post monsoon and thus there was no flow in the river. The study of soil erosion and sediment yield in the Indian Arid Zone was conducted by Central Arid Zone Research Institute, Jodhpur (CARZI).
The arid zone of India has been subdivided into three zones. The Zone – I (42900 sq.km) is a humid region and has more dependable irrigation system through perennial rivers. It comprises of part of Punjab and Haryana and is irrigated by Abohar and Bhatinda branch system. Zone-II (148600 sq.km) comprises of sandy plain, interdune plains, sand dunes and isolated hillocks. It covers Ganganagar, Bikaner, Jodhpur, Jaisalmer, Barmer, Churu, Jhunjunu, Sikar and Nagor district in Rajasthan. Zone – III represents the sloping region with intergrated drainage network of ephemeral river channel. In Rajasthan it extends over Pali, Jalore and Sirohi districts. The hydrological zones of arid region of India is shown in Figure 7.1.

Figure 7.1 : Hydrological Zones of Arid Region of India The approach of the study was to collect information on the spatial variation of stream discharges and the sediment yield for 34 Gauge and Discharge site (G& D) in the zone on various tributaries of the Luni River. The discharge rate for run-off and the sediment concentration for 16 years was analyzed for computation of sediment yield. Wide variation in the magnitude of annual sediment yield was observed for different physiographic reasons. The results plotted in figure shows skewed frequency distribution. The annual sediment yield results thus obtained are shown in Table 7.1 and the relationship developed between sediment yield and effective rainfall is depicted in Figure 7.2. The relationship developed is
0.99 Es=3.68ER , where ER is effective rainfall (mm) and Es is sediment yield. The annual sediment yields from the other physiographic reasons are in agreement with mean rates reported from the arid regions of Australia, Tanzania and USA (Jones, 1981) under similar rainfall conditions.

7.2.2.2 Empirical Relation Sediment load remains ungauged for majority of streams for want of setup of GDS sites (Gauge, Discharge and Sediment) in non-classified river basins. Many empirical relations have been evolved for determination of offsite deposition of eroded soil and sediment yield on the basis of analysis of data from different catchments of varying catchment area. The sediment yield has been worked out on the basis of some of such equations as applicable for Indian conditions and
a) Dr. A.N. Khosla’s Findings : y = 0.036 million cubic meter / 100 sq.km of catchment = 3.60 cubic meter/ha
Recent studies carried out in some of the Indian reservoirs suggest that actual silting observed in them is higher than what was postulated in Dr. Khosla’s Findings. The enveloping curve developed by Dr. Khosla had only five points pertaining to data of Indian reservoir while the remaining 33 points related to the reservoirs of other countries. The sediment rate of 3.60 cubic meter / ha is 7.2 % less than 3.88 cubic meter / ha as actually assessed on the basis of relationship developed between sediment yield effective rainfall by CARZI Jodhpur on the basis of actual observation of stream discharges and sediment yield in the zone of various tributaries of Luni river.
b) Dr. D.V. Joglekar Enveloping Curve y=0.597/A0.24 where y= annual silting rate in million cubic meter per 100 sq. km. A= Catchment area in sq. km. For 1sq km catchment area the value of y y = 0.597/10.24 = 0.597 million cubic meter / 100 sq km = 5.97 cubic meter/ ha
EQMS INDIA PVT. LTD. 5 The sediment rate of 5.97 cubic meter / ha is 53.9 % more than 3.88 cubic meter / ha as actually assessed by CARZI Jodhpur on the basis of actual observation of stream discharges and sediment yield in the zone of various tributaries of Luni river. c) Dr. R.S. Varshney’s Regional Enveloping Curves for Northern Indian River For plain rivers with catchment upto 1000 sq.km. y=0.392/A0.202 where, y= annual silting rate in million cubic meter per 100 sq. km. A= Catchment area in sq. km. For 1sq km catchment area the value of y y = 0.392/10.202 = 0.392 million cubic meter / 100 sq km = 3.92 cubic meter/ ha The sediment rate of 3.92 cubic meter / ha is 1 % more than 3.88 cubic meter / ha as actually assessed by CARZI Jodhpur on the basis of actual observation of stream discharges and sediment yield in the zone of various tributaries of Luni river.
d) Garde and Kothyari The author have analysed data from 50 catchment with an area ranging from 43 sq. km to 81880 sq. km and evolved the following equation for meet annual sediment yield.
0.6 1.7 0.25 0.1 0.19 Sam = CP Fe S Dd (P max/P) Where,
Sam = mean annual sediment yield in cum C = A co-efficient depending on the geographical location of the catchment P = Average annual rainfall in cm S = Land slope Dd = Drainage density in km/ sq.km. P max = Average maximum monthly rainfall A = Catchment Area in sq.km. Fe = Erosion Factor defined as under
Fe = (0.8 FA + 0.6 FG +0.3 FF + 0.1 Fw) /A Where,
FA = area of available land in catchment
FG = area occupied by grass and scrub
FF = area of forest land
FW = area of waste land On the basis of analysis of 154 catchment in India Garde and Kothyari produced an ISO- Erosion Rate Map of India (Figure 7.1). In the absence of any other information the erosion
EQMS INDIA PVT. LTD. 6 rates in tonne / sq. km / yr, for planning purposes, can be obtained by using the map. As per the map the study area lies between contours of 350 tonne / sq.km / yr and 1000 tonne / sq. km. / yr erosion rate but it is close to the latter. In any case the average value of 600 tonne / sq.km. or 4.25 cubic meter / ha can be conservatively adopted.

e) Dandy Bolten Study Dandy and Bolton studied sedimentation data from about 1500 reservoirs, ponds, and sediment detention basins with drainage areas between 1 to 30,000 sq.mile and found that the annual sediment yield per unit area was inversely related to the 0.16 power of the drainage area:
Where, S = Sediment yield in tons per square mile per year;
SR = Reference sediment yield of 1645 tonne/year corresponding to a 1 sq. mile drainage
EQMS INDIA PVT. LTD. 7 area, A = Drainage area in square miles AR = Reference drainage area in square mile
Dandy and Bolton also analysed sedimentation and mean annual runoff data from 505 reservoirs and inferred that annual sediment yield per unit area was increases sharply as mean annual runoff Q increases from 0 to 2 inches and thereafter, it decreased exponentially. This led to the following equations.
For Q<2 inches
- - - - - Eq. 1
For Q >2
inches - - - - - Eq. 2
Where, QR = reference mean annual runoff QR = 2 inches Dandy and Bolton combined Eqs. 1 and 2 into a set of equations to express sediment yield in terms of drainage area and mean annual runoff.
For Q <2 in.: - - - - - Eq. 3
For Q > 2 in.: - - - - - Eq. 4
2 Putting values of SR = 1645 tons/mi /y, QR = 2 inches, and AR = 1 sq.mile, Eq. 3 and 4 reduces to the followings set of equations: - - - - - Eq. 5 For Q <2 in.: S = 1280 Q0.46(1.43 – 0.26 log A)
-0.055Q - - - - - Eq. 6 For Q >2 in.: S = 1965e (1.43 – 0.26 log A)
In several cases, local factors such as soils, geology, topography, land use, and vegetation may have greater bearing on sediment yield than either mean annual runoff or drainage area. Nevertheless, these equations provide a first approximation to be regional assessment of sediment yield for watershed planning purposes. Equations 5 and 6 are based on average values of grouped data; therefore, they should be used with caution. Besides Dandy & Bolton themselves has category stated that use of the equation to predict sediment yield for a specific location would be unwise because of the wide variability caused by local factors not considered in the equation development. Actual sediment yield form individual drainage basins may vary 10-fold or even 100-fold from computed yields.
EQMS INDIA PVT. LTD. 8 In the present case for effective catchment of 1210 sq.km and the mean annual runoff corresponding to monthly average of 423 mm for the observed data from 1973 to 2012 has been computed as under.
Estimation of mean annual runoff on the basis of empirical relation as applicable to the study area falling in Rajasthan.
R = (P-175)/2500 X P = 33.1 mm
Since the mean annual runoff is less than 2 inches, Eq. 5 shall be adopted for working the sediment yield.
S = 1280 Q0.46(1.43 – 0.26 log A) = 372.83 metric tonne/km2/yr or 3.73 metric tonne / ha or 2.66 cubic meter / ha.
The annual sediment rate on the basis of Dandy Bolten equation are lower than the rates arrived on the basis of actually assessed by CARZI Jodhpur on the basis of actual observation of stream discharges and sediment yield in the zone of various tributaries of Luni river

7.2.3. Computation of annual Sedimentation load: The major drainage flowing through Tehsil Pali are Khardi, Mithri, Bandi, Somesar, Ugti, Sukri and Khari. These drainages form part of sub-watershed 6A2C3 and 6A2C4 as per Watershed Atlas of India and marked in catchment area map (Figure 3.6). Sediment production occurs in the drainage basin and sediment delivery is limited to major flood flows. When run-off occurs from severe storms or torrential rainfall flash floods of high magnitude flow in the drainage system along with large quantities of sediments which are transported through the rivers and get deposited at depositional or convex banks due to slower velocity of flow. Thus it is apparent that any sediment particle detached from its original configuration shall take time to reach the streams for onwards journey. The lower order streams (1st and 2nd order) generate more sediments due to their higher bed gradient but it is the higher order streams flowing with large discharge responsible for creating high tractive force needed for transportation of bed load and suspended sediments.
With rivers flowing through different tehsils / district it is not feasible to confine the watershed into one tehsil. Depending upon the topography, the area in anyone tehsil could be the catchment for nearby drain/stream flowing in contiguous tehsil/district. Besides this the drainage basin in tehsil/district has been harnessed in the form of reservoir and tanks created across the main rivers and their tributaries the details of which are provided in Table 7.4. During flood the silt ladden discharge is intercepted by the structures and is entrapped in thse reservoirs except for the period of outflow from the dam which is possible only when the inflow into the dam exceeds the reservoir capacity. In case of smaller weirs/sluice/dams the condition of outflow is invariably achieved during good monsoon season. But by contrast this situation is none-to-happy in context of larger dams as in the case of Jawai Dam which has been filled to its FRL only in 9 years out of 56 years as is evident from Table 7.5. For transportation of the sediment it is necessary that the rivers flow during monsoon which is possible only in case of smaller tanks and reservoirs. The pictorial view of prominent dam in tehsil is shown in Figure 7.3.
The total catchment area of the rivers flowing within tehsil has been assessed as 1546 sq.km and after accounting for the intercepted catchment by different reservoirs, tanks, weir, anicuts, dams, and the effective catchment area is 1210 sq.km. The sediment yield from this portion of catchment @ 549.89 tonne/sq.km works out to 0.67 million tonne/year. The project envisages annual production of 2.24 million tonne or 11.2 million tonne in 5 years lease period. Thus the annual extraction exceeds the annual deposition by 1.57 million tonne which implies that the
EQMS INDIA PVT. LTD. 10 deposition rate is about 70% lower than the annual extraction rate. The mine pits will get replenished provided there are two to three events of floods in every monsoon. The replenishment takes place faster during the first flood and thereafter the rate of replenishment decreases. For safe replenishment of river bed mine pits it is necessary that the mining activities are carried out in such reaches which are susceptible to deposition like the convex banks. Since the mineable reserves are 126.84 MMT against which 11.2 MMT can be safely extracted during the lease period without taking into account the annual replenishment. The area mined out every year will get replenished after two consecutive good monsoon seasons, reckoned from the end of pre-monsoon season of the year of extraction, provided the free reach of the river receive run-off from three to four events of flood every monsoon. It is therefore assessed that the mined out area within 5 years shall be completely replenished after 13 years reckoned from the cessation of the mining provided every year average annual rainfall during rainy season (423 mm) occurs in the catchment.

Annexure – IV: Cumulative impact or other mines located in the vicinity of the lease area needs to be submitted.
1.1. Cumulative impact of other mines in the vicinity of lease area in Tehsil Pali. The cumulative impact of other mines and the riverbed mine lease area can be two prong viz. the impacts of each other due to mining activities and also on environment; and impact on roads due to transportation. 1.1.1. Description of Present and Existing Mines The present rivebed lease area (3859.0 ha) in Tehsil Pali is constituted by summation of linear area along different ephemeral river(s) like Somesar, Khari, Sukri, Bandi, Mithri and Khardi which cover a longitudinal profile of 23 km, 20.5 km 28.5 km, 31.5 km, 10 km and 9 km respectively in the Tehsil. Besides the riverbed lease area there are 77 other leases with consolidated area of 228.82 ha. These include 28 masonry stone mines of 1 ha each and 49 Granite mines of total area 200.82 ha. which are located in village Kharda Ki Dhani (3 nos.), Kharda (3 nos.), Jawaria (6 nos.), Giradara (2 nos.), Sakadara (27 nos), Dari (6 nos), Bala (1 no.) and Denda (1 no.). The masonry stone mines are located in villages Manihari (6 nos.), Akali (1 no.), Sodawas (1 no.) and Sowaniya (1 no.), Madri (1 no.), Bhanwari (14 nos), Dayalpura (3 nos), Nandan Batan (1 no.). The location map of the existing mines including the riverbed mining in Tehsil Pali is shown in Figure 1.1.
Figure 1.1 : Location of Riverbed lease area and Other Mines 1.1.2. Impact of Riverbed Mining on Existing Mines The semi-mechanized river bed mining in 3m depth (maximum) shall be carried out in the riverbed section of numerous river draining the Tehsil. The lease area is a linear area along different river(s) like Somesar, Khari, Sukri, Bandi, Mithri and Khardi. All these rivers are ephemeral rivers and influenced by nature due to good alluvium material constituting their river bed matrix. During monsoon season and especially during flash flood regime the rivers with significant free draining catchment reach high stage and transport suspended sediment of high concentration and larger amount than the bed load material. The bed load material/sediments which get accredited at such stretch which has wider river width and has concave banks during the passing of the floods while the suspended particles settle on the receding of floods. The mined out area in river bed thus gets partially replenished only in the eventuality of frequent storm events which cause heavy run-off to pass through the river. The existing other leases are not located in the riverbed and are approximately 1.2 km to 3.9 km away from the nearest boundary of mine lease area. Thus any riverbed mining activity which is confined to the river section alone shall not impact any of the other leases either due to channel incision or due to flooding and over toping of flanks of the river and inundating the other lease areas. Based on air quality dust dispersion modelling it has been observed that the fugitive dust emission resulting from the mining activity and the haul road transportation has been found to be insignificant (0.5ug/cum) about 450m away from the mining sites and thus the nearest site which are located about 1.2 km shall not be impacted on this count. As regards the impact due to noise it is evident from the graphical results that the noise level of 85 dB(A) gets highly attenuated to 42 dB(A), 37 dB(A) and 32 dB(A) about 145m, 340m and 440 m respectively from the point source. As the mining activity in riverbed shall not generate any effluent therefore the incidence of its disposal in the nearby other lease areas is a far gone possibility. 1.1.3. Impact of Riverbed Mining on Other Riverbed Mines of Adjacent Tehsils Bandi river and its tributaries originate from the Aravali ranges and flow from East to West in Tehsil Marwar. The upper most extremity of the lease area along these rivers begins after these have debouched from the Aravali range to the plain land of the Tehsil. These rivers after traversing through Tehsil Marwar Jn. with catchment area (1844 sq.km) drain through Tehsil Pali with absolute catchment area (1546 sq. km). Sukri river and its tributaries Lilri and Modiya Nala which also originate from the Aravali ranges and flow from East to West in Tehsil Sojat without flowing through Tehsil Marwar Jn. and has its own catchment area (1824 sq.km). These rivers after draining through Tehsil Sojat enter into Tehsil Rohat and finally confluence with main river Luni. The rivers while flowing through Rohat tehsil has an absolute catchment area (1554 sq. km). Jawai and Sukri rivers originates from Aravali ranges of Udaipur and flows from South to North-west before confluence with Luni river. Mithri and Ugti rivers after flowing through Tehsil Bali and Rani enters Sumerpur Tehsil. These rivers constitute a combine catchment of 1186 sq.km. The flow course of these rivers is such that they do not drain through Pali / Marwar / Sojat / Rohat Tehsils. The composite map of the catchment areas under different Tehsil is shown in Figure 1.2. Based on the effective catchment areas for different Tehsil and corresponding effective rainfalls the annual sediment yield computed on the basis of empirical formula developed by CAZRI, Jodhpur is enumerated in Table 1.1.
Figure 1.2 : Composite Catchment Area Map
Table 1.1 : Tehsil-wise Details of Catchment Area and Annual Sediment Rates Tehsil Catchment Area (sq.km) Annual Sediment Rate Total Effective Tonne / sq.km Cum/ha. Marwar Jn. 1844 1150 582.52 4.11 Sojat 1824 1075 556.37 3.93 Pali 1546 1210 549.89 3.88 Rohat 1554 1215 559.44 3.95 Sumerpur 1186 593 814.40 5.75
The catchment area of rivers flowing through Tehsil Pali is independent of rivers flowing through Tehsil Sojat/Rohat and its disposition is such that it constitutes the lower catchment for river flowing through Tehsil Pali. The flow course of rivers flowing through Tehsil Sumerpur is such that they do not drain through Pali / Marwar / Sojat / Rohat Tehsils. It is thus evident that the mining activity in rivers flowing in Tehsil Pali and consequent replenishment in monsoon seasons shall not be impacted due to mining activities in Tehsil Sojat / Rohat and Sumerpur as the rivers flowing in these Tehsils have different catchment. The catchment area of rivers in Pali Tehsil forms lower catchment for drainage through Tehsil Pali which has adequate and reasonable catchment to produce and transport sediments.
1.1.4. Impact of Existing Mines on Riverbed Mining The existing other leases of masonry stone and other minerals are not located in the riverbed and are approximately 1.2 km to 3.9 km away from the nearest boundary of mine lease area. Thus mining activities, which have been going for years shall be confined to the existing pit(s) alone. Due to bottom pit levels of other leases (Other minerals) being lower than the riverbed levels of nearby riverbed mine lease area, the chances of ingress of surface water into the pits of adjacent mines are ruled out during dry period mining but cannot be precluded during flood season if the mines are located in close vicinity. However, during rainy season, the pits of the existing mines are also inundated with rain water, the difference of free surface level of water of the two may not attract any ingress. This situation shall not arise as the mines are more than 1.2 km away from each other. However, the pumped out water from the pit of other mines discharged into nearby Balas may bring silt laden water which may finally drain into the nearby lease area during heavy precipitation. 1.1.5. Cumulative impact on carrying capacity of roads due to transportation of minerals The annual production of river sand, from different rivers, envisaged from tehsil Pali, Rohat, Marwar Jn., Sojat and Sumerpur shall be to the tune of 2.24 MMT, 2.24MMT, 1.12 MMT, 1.40 MMT and 1.12 MMT respectively. This sums up to 8.12 MMT / annum i.e. 29000 tonne/day for transportation of which 1450 trucks (20 Tonne) shall be required. The increased traffic load due to transportation of mineral shall not be concentrated in a particular segment of the road as the material shall be dispatched to different destination and in different directions. The impact due to transportation shall be on carrying capacity of the State Highway/ National Highway and also due to increase in vehicular emissions due to mineral transportation. The transport plan for movement of trucks through these Tehsils is shown in Figure 1.3 which reveals that bulk of material shall be carried out through NH-14, NH-65, SH-16, SH-58, SH- 61, SH-62, SH-65, SH-67. The traffic survey is essential to realistically and accurately assess the prevailing traffic volumes and travel characteristics by undertaking classified volume count. The objective of traffic volume count survey is to assess the traffic intensity on the most vulnerable section of the road under question. Two – days, 24 hrs., continuous volume counts were manually undertaken during November 2013 at different locations on NH/SH for capturing the realistic picture of the current volume and composition of traffic motorized i.e. passenger vehicles (two- wheeler, three-wheeler, bicycle, passenger car); utility vehicles (Jeep, Van, Mini Bus, Standard Bus); Goods vehicles – LCV (Freight), MCV (2 axle rigid chasis), MCV (3 axle rigid chasis), MAV and tractor trailer and non-motorized like animal driven cart. The analysis of traffic counts provides an estimate of average daily traffic (ADT). The study for carrying capacity has been carried out for these roads by undertaking traffic volume counts at the prominent inter-junction of these roads as per guideline of IRC:9-1972 and IRC:SP 19-2001 and the PCU factors adopted for analysis has been taken as per IRC:64- 1990. The ratio of traffic volume to capacity and consequent level of service (LOS) in pre and post project scenario is evaluated for different highways and different locations and shown in Table 1.2 which manifests that in case of NH – 14 the existing level of service in respect of NH -14 at Sumerpur, Pali and Sojat (Bagawas) being ‘A’ , ‘A’ and ‘B’ respectively shall not change in case of Sumerpur and Pali but it will change to ‘C’ at Sojat (Bagawas) respectively in post- project scenario. In case of NH-65, the existing level of service at CARZI and Rohat being ‘B’ shall change to ‘C’ in post project scenario. The existing level of service in case of SH-64 is ‘A’ which shall change to ‘B’ in post project scenario, whereas the existing level of service for SH-61 being ‘B’ shall change to ‘C’ in post project scenario. There shall be no change in the existing and post project level of LOS in case of SH-16, SH-58, SH-62 and SH-67.
