2 Project Description The Government of Uttarakhand (GOU) wishes to develop an aerial passenger ropeway between Kaddukhal & Surkanda Devi Temple in order to promote tourism in the region. The proposed ropeway shall be developed through Public Private Partnership mode on Build, Operate and Transfer (the BOT ) basis. The Project is a 500 m long ropeway, covering an area of 5620 sq m (including Lower Terminal Station, Upper Terminal Station & ropeway corridor). Lower Terminal Point (LTP) and Upper Terminal Point (UTP) are proposed near Kaddukhal and Surkanda Devi Temple. Type of Project The project being an Aerial Ropeway falls under the item 7 (g) of the EIA notification, 2006 and is a designated Project as per Schedule and falls under category A, as the Temple is at an elevation of 2737 m above MSL. Project Proponent Uttrakahnd Tourism Development Board (UTDB) as part their initiative to improve tourism based facilities and socio economic structure of local population directed Uttrakahnd Infrastructure Project Company Private Limited (UPIC) (a 50:50 joint venture company between Government of Uttrakahnd and ILFS) to undertake detailed Feasibility and Project Viability Analysis for establishment of passenger ropeway to the temple of Surkanda Devi. UPIC on their part issued RFP/RFQ documents to prospective bidders in October 2012; after ascertaining project viability and obtaining all mandatory approval for the captioned project. The Surkanda Devi Ropeway Project was awarded to M/s K. R. Anand and M/s KRA Infrastructure Developers Pvt. Ltd. through competitive bidding and letter of award (LOA) on A special purpose company was formed as Surkanda devi Ropeway Project Company Private Limited for design, construction, operation and maintenance of the ropeway project under revenue sharing model. The lease duration of the project is 30 years, extendable by an additional 10 years. 2

3 Description of Project Site: Surkanda Devi temple is dedicated to Sati-wife of Lord Shiv. According to the legend, Sati gave up her life in the argument with her father, as Prajapati Daksha was not ready to accept Shiv as her daughter's husband. It is said that Lord Shiv brought Sati's dead body, on his trishul to this place from Haridwar. Because Lord Shiv was dancing furiously with the dead body of his wife, Lord Vishnu started cutting the body parts of Sati with his Sudarshan Chakra. The head of Sati fell at this place and hence the place got the name Surkanda. Temple is situated on the peak of a hill approachable by 1.6 km fairly steep foot path from the nearest motorable road. It is surrounded by dense forests and affords a scenic view of the surrounding region including the Himalayas to the north, and certain cities to the south (e.g., Dehradun, Rishikesh) Need/Justification of the Project: Presently the devotees face hardship in climbing this stretch of approach to the temple. This ropweway system is proposed to negotiate this tough reach in a comfortable & environment friendly way. Location of the Project Alignment Surkanda Devi Temple is situated on the peak of a hill at Village Kaddukhal in the western part of Tehri Tehsil, District Tehri Garhwal, Uttrakhand. The temple is at elevation of 2737 m from MSL. The lower terminal Station, Kaddukhal is on Dhanaulti- Chamba road. Kddukhal is at 40 Km distance from Mussoorie, 75 Km from Dehradun & at 8 Km distance from Dhanaulti.The location map of the Project alignment is shown below: 3

6 Road: The nearest road head is at Kaddukhal which is connected by road going from Dhanaulti to Chamba. Surkanda Devi Temple is 1.6 kms from Kaddukhal on foot. Area Requirement: The area required for the construction of the terminal stations and line towers would be about 5620 sqm. The detailed area summary is given below: Area required for Area (sq m) Lower Terminal Station, 300 Kadukhal Upper Terminal Station, 300 Surkanda Devi Temple Ropeway corridor 5020 Total 5620 sq m Alternative routes assessed Five alternative routes were assessed, which are as discussed below: Alternative Latitude Longitude Elevation Difference Alternative I LTP N LTP E 215 m UTP N UTP E Alternative-II LTP N LTP E 231 m UTP N UTP E Alternative-III LTP N LTP E 291 m UTP N UTP E Alternative-IV LTP N LTP E 226 m UTP N UTP E Alternative-V LTP N LTP E 223 m UTP N UTP E 6

7 Selected Alignment: Out of the five alternative routes the Alternative-II was found appropriate as it was the most stable stretch, the requirement of space was minimum and minimal no. of trees will be disturbed. Also, the UTP is located reasonably away from the Shrine so as to not cause any interference. The five alternative alignments are shown in the figure below: The total length of proposed ropeway alignment is working out to be 500 m. The LTP is proposed near GMVNL rest house at Kaddukhal. The UTP is proposed near the Dharamshala towards South West on gradual slope. Merits of the selected Alignment: The alignment for the proposed ropeway project was selected based on the following guidelines: i) Availability of adequate space for proposed terminal stations; 7

8 ii) iii) iv) Low density of forest cover thereby reducing number of trees to be felled; Major points / locations to be connected along the route; Minimum possible infringement with the environment; v) No rehabilitation or relocation involved vi) vii) Stability of the location vis-à-vis geology; and Financialfeasibility of constructing terminal stations. viii) Minimum numbers of trees are required to be cut. Proposed Ropeway System Technology Mono-cable Jig back system In this system one endless hauling rope supports and hauls two cabins, one in forward direction and the other in reverse direction between the terminal stations. The cabins are fixed to the rope. Once the cabins reach the terminal stations the movement of the ropeway is reversed. Mono-cable uses cabins of comparatively lower passenger carrying capacity. Advantages Reduced terminal space requirement Cost effective Simplicity of operation and maintenance Constraints Low transportation capacity Specifications & Guidelines The specifications and guidelines are provided for the various project components (Ropeway System, associated infrastructure) including, but not limited to the following major provisions: The Concessionaire shall consider Specifications provided by Bureau of Indian Standards and other applicable statutory code of practices like Indian Electricity Act, National Building Code, 8

9 Municipal Building Bylaws of Uttarakhand, etc for design, construction, operation and applicable maintenance of the project facilities. The Concessionaire shall adhere to the provisions of any Act for passenger ropeway that is applicable for enacted in future in the state of Uttarakhand. In case of ropeway Cabins and its associated part to be mandatorily procured imported, suitable international standards with justification may be followed. Maintenance Schedule: Detailed operation and maintenance instruction manuals covering all aspects of maintenance of the Ropeway System would form an integral part of system documentation. The essential aspects of maintenance are, however, briefly listed below: cabins, hangers and grips etc shall be done. Periodic lubrication at the Stations shall be done. Routine lubrication at the Stations. Regular cleaning at stations to ensure a clean and dust-free atmosphere. Periodic Inspection, checking and replacement of hauling rope especially the spliced zones. Inspection, checking, lubrication and replacement if and when required of line components such as line sheaves. Tightening of all station tower bolts periodically. Checking of prime mover such as motors, gearbox, couplings etc. Regular checking of service and emergency brakes. Regular checking of DG set and Diesel Engine. Mock trial of rescue system at periodic intervals. Adequate maintenance spares will be stocked for smooth operation. Special tools & tackles will kept in the workshop 3. ENVIRONMENT MANAGEMENT PLAN Land Environment: Construction phase: 9

10 The land is a forest Land, of which 0.68 ha has been procured for the project. There is no eco sensitive zone within the 10 Km radius of the project alignment. The diversion of forest land will be required for construction of terminal stations, and line towers along the corridor. Operation Phase: Although no major impact on land is envisaged during the operation phase, proper collection shall be taken care for no disposal of solid or hazardous waste & wastewater on land. Air Environment Construction phase: During the construction activities for the proposed terminal stations there will be fugitive emission such as particulate emission etc. on small scale. Water sprinkling shall be done to mitigate the impacts of dust generation. The particulate emissions will be minimal and short term in nature. For the construction of line towers, the generation of the dust will be low as compared to the construction of terminal stations. Moreover, the dust generated during the construction phase will be considerably reduced due to localized meteorological conditions. Operation Phase: The operation of the proposed ropeway will not involve major air emissions. Ropeway operation is an environment friendly non-polluting transport system. DG set of 750 KVA are proposed at LTP & DG set of 15 KVA are proposed at UTP for backup power supply. These D.G. Sets will be provided with proper stack height as per the CPCB norms. As per the specifications from D.G. Set manufacturer, the emissions rates that shall be maintained are given in Table below: D. G. Set. Capacity No. Location PM gm/kw-hr NOx gm/kw-hr SO 2 gm/kw-hr CO gm/kw-hr 750 KVA 1 LTP kva 1 UTP

11 The impact of pollutants such as SO 2, NO x and CO mainly released from D.G sets and their concentration & impact will be very negligible and of short term duration. The system will be operated mainly on electricity provided by Grid. DG sets will be used as a stand-by only at the time of power failure. Noise Environment Construction Phase: The noise emission sources during construction phase will include construction machineries/ equipments to be employed at site. The management measures for noise & vibration control are as follows: Standard methods and machinery shall be used. Job rotation and provision of earmuffs to the workers in high noise areas. Operation Phase: DG set of capacity 1 X 750 kva at LTP and DG set of 1 X 15 kva at UTP are proposed for backup power supply. Acoustically enclosed DG Sets will be bought and installed. The noise & vibration management measures are discussed below: Noise free and less air pollution emitting, acoustically enclosed DG Sets, approved by the CPCB will be bought and installed. The system will be operated mainly on electricity provided by Grid. DG sets will be used as a stand-by only at the time of power failure. DG sets shall be installed on proper vibration pads to avoid vibration impacts. The noise pollution due to operation of DG set can be controlled by installation of silent cowling to a value of 65 db (A). The normal ropeway operations are always lower than 50 db (A) of noise level. Proper maintenance of the ropeway during the operational phase will be done to ensure low or no noise and environmental impacts. 11

12 Water Environment Construction Phase: During construction Phase, water will mainly be required for ropeway development, dust suppression & human consumption. It is estimated that around 5 KLD of water shall be required. Operation Phase: The total water requirement has been estimated as 15 KLD as per detailed below and the source will be Spring Water. Water shall be used mainly for flushing, drinking, hand washing & horticulture purposes. Total quantity of waste water generation has been estimated to be 9 KLD. The waste water generated will be treated in 2 STPs of 10 KLD each. S.

13 WATER BALANCE SCHEME OF SEWAGE TREATMENT PLANT The generation of total waste water will be 9 KLD, which will be treated in total 2 sewage treatment plants of 10 KLD capacities each based on FAB (Fluidized Aerobic Bio-reactor) Technology. DESIGN CRITERIA TREATMENT PROCESS: THE PROCESS FOR SEWAGE TREATMENT PLANT IS AS FOLLOWS: The sewage is first passed through a Bar Screen Chamber & an Oil & Grease Chamber where any extraneous / floating matter gets trapped. 13

14 The sewage is then collected in a Receiving Sump where the variations in flow and characteristics are dampened, which otherwise can lead to operational problems and moreover it allows a constant flow rate downstream. Here the sewage is kept in mixed condition by means of coarse air bubble diffusion. The equalized sewage is then pumped to the Fluidized Aerobic Bed Reactors (FAB) where BOD/COD reduction is achieved by virtue of aerobic microbial activities. The FAB reactors run in series. The oxygen required is supplied through coarse air bubble diffusers. The excess bio-solids formed in the biological process are separated in the downstream Tube Settler Tank. The clear supernatant after disinfections is sent to the tertiary polishing section comprising of a Dual Media Filter and an Activated Carbon Filter, passes through Softener for reducing the hardness. The biological sludge generated from the FAB, which is settled in the Tube Settler, is drained through the Filter Press. Raw Sewage Characteristics Flow m 3 / day 10 KLD each ph BOD mg / l COD mg / l TSS mg / l 100 Oil & Grease mg / l 10 The Sewage Treatment Plant (STP) can give treated water, which can be reused for Flushing, Hand washing & other miscellaneous purposes. 14

15 Treated Sewage Characteristics ph BOD mg / l <10 COD mg / l <60 TSS mg / l < 10 Oil & Grease mg / l < 10 Benefits: 1. Small space requirement The concept of compact sewage treatment plant is promoted so that expensive conventional treatment is dispensed herewith. The treatment scheme is also versatile, in the sense that units can be re-arranged in any way in which the space and pile caps are available. 2. Lower operating power requirements The system utilizes aeration tanks of much smaller size, thereby reducing the overall power required in aerating the raw sewage. Since the bio-reactor depth is more, efficient transfer of oxygen takes place, thereby reducing the overall power consumed in treatment. 3. Simplicity in operation and maintenance The system adopted has much less moving parts (only pumps and blowers). Further there is no moving part inside the bio-reactor. This gives the advantage of continuously running the bioreactor system, under widely fluctuating conditions. All the maintenance on the mechanical systems can be done with normal skilled mechanics available. The system is unique in operation, such that, only inlet and outlet parameters (i.e. raw sewage BOD / COD / TSS /TP and treated sewage BOD / COD / TSS / TP etc.) need to be analysed. Since the bio-reactor is self sustaining, there is no requirement of recycling the biomass from the secondary clarifier. Hence, analysis such as MLSS / MLVSS / SVI (sludge volume index) / F / M ratio etc. is not required to be done. This greatly reduces the analytical load on the plant chemist / supervisor, and makes the system very simple to operate and control. 15

16 The bio-reactor system adopted in the FAB based STP is provided with nutrients removal, and removal of disease causing E-coli bacteria. 4. Nutrient removal The bio-reactor system operates at very food to micro-organisms ratio (F / M ratio). This helps in totally converting the Ammonical nitrogen to nitrate nitrogen. In the process of synthesis of organic substrate, about 40 50% of the total phosphates load is also reduced. The remaining phosphates can be precipitated by addition of aluminum ions dosed in form of Poly Aluminum Chloride (PAC). Phosphates react with aluminum ions and precipitate as aluminum phosphate, which is an insoluble salt. Thus the total phosphates load can be easily reduced by more than 90%. 5. Coliform removal The outlet BOD of the bio-reactor system being very low (in other words, hardly any food is available to the E-coli), most of the coliform are killed in the reactor itself. The treated sewage outlet coliform count will conform to WHO standards. 6. Sludge handling The sludge generated in the bio-reactors is totally digested. Since the F / M ratio in the bioreactors is very low, the excess sludge generation is lower than compared to the conventional ASP system. Normally, this sludge is anaerobically digested to stabilize the organic matter. The present system does not envisage any sludge digestion (since the sludge is aerobically stabilized in the bioreactors itself), making the system more suitable for operation with less manpower. The excess sludge is separated in the secondary clarifier, and then disposed off either on drying beds, or can be directly used as soil conditioner. 16

17 P G PG HYDRAULIC FLOW DIAGRAM OF SEWAGE TREATMENT PLANT Storm Water Management Maximum collection of rain water shall be done and the stored water shall be reused wherever possible. Garland drains are proposed around the pillars/towers to ensure the proper drainage of the storm water and to prevent disturbance to the drainage pattern of the area. Solid Waste Management Construction Phase: Wastes which are likely to be generated during the construction of terminals include the following: Municipal Waste: Site clearance Construction Waste: Construction materials arising from the construction may include waste timber work, spent concrete and cement screening and material and equipment wrappings. 17

18 Excavated materials: Excavation during pillar foundations will lead to generation of excess soil. Top soil will be used for landscaping and left out soil will be used for land filling. Local labors will be preferably employed; no labour camp will be setup at the site. Approx. 3 Kg/day wastes will be generated which will be sent to solid waste/landfill site. Operations Phase: During operation phase, solid waste will be generated by ropeway users, employee, etc. The estimates of the solid waste generated from the proposed project have been shown in table below: Type of Waste Colour of Bin Category Disposal Method Total Waste (kg/day) Organic Waste Green Biodegradable The waste will be disposed by pyrolysis method 92 Recyclable Waste Total Waste Blue Recyclable Collected and given to approved recycler kg/ day The above table indicates that the total 153 Kg/day of waste will be generated due to the proposed development. The waste oil generated from D.G sets will be sent to authorize hazardous waste disposal authority. Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen (or any halogen). It involves the simultaneous change of chemical composition and physical phase, and is irreversible. The waste is broken down to create gas, solid and liquid residues. The gases can then be combusted in a secondary process. Most pyrolysis processes have four stages: 18

19 1) Preparation of the waste feedstock: The plant may take mixed waste and process it first through some sort of materials recycling facility, to remove some recyclables and materials that have no calorific value (e.g. grit) 2) Heating the waste in a low-oxygen atmosphere to produce a gas, oils and char (ash) 3) Scrubbing (cleaning) the gas to remove some of the particulates, hydrocarbons and soluble matter 4) Using the scrubbed gas to generate electricity and, in some cases, heat (through combined heat and power CHP). There are different ways of generating the electricity from the scrubbed gas steam turbine, gas engine and maybe some time in the future, hydrogen fuel cells. Benefits: Stable operation for a broad range of waste quality Emissions from the system are well below the limit values Flexibility in design and operation achieved by a modular design Effective initial waste volume reducing Efficient recovery of the materials and energy from the process Low operational costs; no supplementary external fuel supply for the normal operation, i.e. significant reduction of running costs 19

20 Ecological Environment The alignment falls within a Forest land which needs to be diverted for development of terminal stations & line towers. About 6800 sq m (0.68 ha) of area of forest land will be required to be diverted. This activity will be carried out as per the guidelines of the Forest (Conservation) Act, A compensatory afforestation plan will be developed in the ratio of 1:2 and hence, an amount for plantation of trees in an area of 1.4 hectare will be given to the forest department. 32 trees falls within the corridor of the alignment. Socio Economic Scenario There will be no displacement or immigration of the human population due to the proposed project. Elderly, children and disabled people, who have to climb the arduous steps, will be able to take safe and convenient travel to the holy place. Provide direct and indirect employment opportunities to the local people. Enhance visitor experience and boost tourism in the region.
