After detailed deliberations, the EAC recommended for scoping clearance for the project with the following additional TORs to be followed in the EIA study. a) The outcome of Cumulative Impact Assessment Study of Dhauliganga river (Sarda Basin), (being carried out by Govt. of Uttarakhand) as applicable, would be taken care by the project. b) Biodiversity study shall be carried out by associating a reputed organization as per the list of institutes available on MoEF&CC website. c) Camera trapping to be used for assessment of presence of wildlife in the project area. d) Skill mapping of project affected families shall be carried out and suitable provisions shall be made in R&R plan. e) Efforts to be made to the extent possible, so that no PAF loses their entire land holding on account of acquisition of land for the project. f) Possibility of providing fish ladder/passage in barrage shall be explored for sustenance of fisheries. g) Requisite clarifications / clearances from NBWL shall be obtained by Project Proponent in the light of revised Notification of the Askot Wild Life Sanctuary for the project. 6. The EAC recommended the ToR clearance for the project. Agenda Item No 2.2: Jakhol Sankri HEP (44MW), Uttarakhand, by M/s SJVN Limited- for consideration of ToR. The project had been earlier accorded ToR approval by MoEF&CC on 11.01.2011 vide letter no. J-12011/83/2007.IA.I for a period of two years for an installed capacity of 51 MW. The project proponent informed that the work of preparation of EIA/EMP report was given to M/s WAPCOS Ltd. who had recommended Environmental Flow releases as per standard ToR of MOEF&CC of 30% during monsoon, 25% during non-lean and non-monsoon months, and 20% during lean period. On account of these environmental releases, the project capacity had to be reduced from 51 MW to 44 MW. Project proponent further informed that no action on extension of time of ToR could be taken due to verdict of Hon‟ble Supreme Court dated 13.08.2013 which had put a ban on any Environmental & Forest Clearance for Hydro Power Projects located in the State of Uttarakhand. The Hon‟ble Supreme Court has now clarified its position on this issue. 2. Project proponent has now come with proposal for seeking fresh ToR approval of 44 MW Jakhol Sankri HEP. Project attracts General Conditions of EIA notification and is a Category „A‟ Project, because it is within 10 Km of Govind Wildlife Sanctuary and National Park. No component of project falls within the Sanctuary/National Park. 3. Project is located in Uttarkashi district of Uttarakhand state and envisages utilization of water of river Supin, a right bank tributary of river Tons of Yamuna Basin. The project envisage construction of a 7.20 m high Barrage (from average river bed level at barrage axis) for diversion of water through a 6.6 km long HRT having dia of 3m to an underground power house (2 x 22 MW) for generation of about 166 MU of design energy. The project is proposed to be completed within 4 years with an estimated cost of Rs.442.31 Crores. 4. The 10 daily Hydrological data series for 35 years for the period 1977 to 2012 has been used in PFR. The 90% dependable year considered for power potential studies is 1984-85. Environmental releases of 30% during monsoon, 20% during lean period and 25% during non- monsoon and non-lean months have been considered. The tentative land required for the project is 39.817 Ha out of which 24.126 ha is forest land and 15.691 ha is private land. The submergence area of 0.24 ha is in forest land. 5. EAC after detailed deliberation recommended for a fresh study of 3 seasons (pre- monsoon, monsoon and post-monsoon) with the following additional ToRs: a) The outcome of Cumulative Impact Assessment Study of Yamuna river Basin, as applicable, would be implemented by the project. b) Biodiversity study shall be carried out by associating a reputed organization as per the list of institutes available on MoEF&CC website. c) Camera trapping to be used for assessment of presence of wildlife in the project area. d) Skill mapping of project affected families shall be carried out and suitable provisions shall be made in R&R plan. e) Efforts to be made to the extent possible, so that no PAF loses their entire land holding on account of acquisition of land for the project. f) Possibility of providing fish ladder/passage in barrage shall be explored for sustenance of fisheries. 6. The project proponent was given a representation as received from Matu Jan Sangthan. The project proponent was asked to consider the issues raised in the representation, during the EIA studies. 7. The EAC recommended the ToR clearance for the project. Agenda Item No 2.3: Sela Urthing Hydro Electric Project, (230 MW) Village Sela- Urthing (Dharchula), Distt Pithoragarh, Uttarakhand, M/s UJVN Limited- For consideration of ToR. Sela Urthing Hydro Electric Project (230 MW) is proposed on Dhauliganga river with Dam near village Sela & Power house near Urthing in Pithorgarh District of Uttarakhand. The ROR scheme envisages construction of 73 m high concrete gravity dam above the deepest foundation across river Dhauliganga, a tributary of River Kali (Sarda). Project was allotted by Govt. of Uttarakhand to UJVN Ltd. (A GoU Enterprise) in December, 2004 for implementation. The total land requirement for the project is about 65 ha., of which 4.0 ha. is private land and remaining 61 ha. is forest land. The surface power house is proposed on the right bank of the river with 2 units of 115 MW each. 2. The project is outside of any wildlife sanctuary / National Park, however, it falls within 10 km buffer zone of Askot Musk deer WLS for which proposal was submitted by UJVNL to NBWL for clearance. The project proposal was recommended by NBWL committee in its 36th meeting held on 04th Nov 2015 for consideration of approval for carrying out survey and investigation works on the project. 3. Hon‟ble Supreme Court vide orders dated 14-08-2014 and dated 12.10.2015 clarified ban imposed on hydropower projects was applicable to 24 hydropower projects mentioned in the report of Wildlife Institute of India, Dehradun.

  • Uttarakhand Flash Flood
    Uttarakhand Flash Flood drishtiias.com/printpdf/uttarakhand-flash-flood Why in News Recently, a glacial break in the Tapovan-Reni area of Chamoli District of Uttarakhand led to massive Flash Flood in Dhauli Ganga and Alaknanda Rivers, damaging houses and the nearby Rishiganga power project. In June 2013, flash floods in Uttarakhand wiped out settlements and took lives. Key Points Cause of Flash Flood in Uttarakhand: It occurred in river Rishi Ganga due to the falling of a portion of Nanda Devi glacier in the river which exponentially increased the volume of water. Rishiganga meets Dhauli Ganga near Raini. So Dhauli Ganga also got flooded. Major Power Projects Affected: Rishi Ganga Power Project: It is a privately owned 130MW project. Tapovan Vishnugad Hydropower Project on the Dhauliganga: It was a 520 MW run-of-river hydroelectric project being constructed on Dhauliganga River. Several other projects on the Alaknanda and Bhagirathi river basins in northwestern Uttarakhand have also been impacted by the flood. 1/4 Flash Floods: About: These are sudden surges in water levels generally during or following an intense spell of rain. These are highly localised events of short duration with a very high peak and usually have less than six hours between the occurrence of the rainfall and peak flood. The flood situation worsens in the presence of choked drainage lines or encroachments obstructing the natural flow of water. Causes: It may be caused by heavy rain associated with a severe thunderstorm, hurricane, tropical storm, or meltwater from ice or snow flowing over ice sheets or snowfields. Flash Floods can also occur due to Dam or Levee Breaks, and/or Mudslides (Debris Flow).

  • Dam Break Flood Hazard Assessment: a Case Study for a Small Dam at Source Stream of River Ganga in Uttarakhand, India Pankaj Mani1, Rakesh Kumar2, J
    Roorkee Water Conclave 2020 Dam Break Flood Hazard Assessment: A Case Study for a Small Dam at Source Stream of River Ganga in Uttarakhand, India Pankaj Mani1, Rakesh Kumar2, J. P. Patra2 1National Institute of Hydrology, Patna, Bihar India. 2National Institute of Hydrology, Roorkee, Uttarakhand India. Corresponding author email id: [email protected] Abstract: Structural measures of a flood defense systems are designed for a specified degree of protection that are defined through the exceedance probability of the flood. However, the failure of major storage structure induces additional flooding risk in the downstream floodplains over and above the specified degree of protection. Hence, the regulating agencies maintains the safety guidelines to include the dam failure while assessing the comprehensive flood risk in the downstream reach. Thus, the dam break analysis evaluates the safety level in the downstream river reach due to flood likely to be induced from storage after the failure of dam with or without the flood generated from meteorological conditions. The comprehensive dam break analysis includes the estimation of the extent and magnitude of flooding, its occurrence time and duration of flooding. The specific flood mitigation measures include preparation of emergency action plans for downstream river reach with computation of available warning time and evacuation plans. The emergency action plans are known to planners, local administrators and even likely to be affected population in priory. The public risk perception helps to develop flood preparedness plan and in efficient risk management strategy. The dam break analysis is essentially a two step procedures, (i) modelling the development of breach in the dam section and computing the breach (flood) outflow, and (ii) routing of flood hydrograph in the downstream river reach to compute the various flood attributes.

As hydro power stations have the inherent ability for instantaneous operations, they are more responsive than most other energy sources, for meeting peak demand and improving reliability of the power system. As such it is important that existing hydro capacity is utilised optimally. Four CPSEs viz., NHPC Limited (NHPC), SJVN Limited (SJVN) THDC India Limited (THDC), and NHDC Limited (NHDC), with 23.72 per cent share in the hydro power generating capacity of the country, have a significant role to play in this regard. In the above backdrop, performance audit was taken up to assess the effectiveness of activities from generation to collection of revenue by these four CPSEs between April 2009 and March 2014. In the wake of incident of flash floods on 16-17 June 2013 in Uttarakhand, specific aspect of disaster management in these CPSEs has also been covered.
