MAJOR DISASTER AGAIN AT KOPILI DAM OF NEEPCO IN ASSAM IN 2022

The 275 MW Kopili Hydropower Dam of NEEPCO (a Union Power Ministry organisation, now under NTPC) has again faced a major disaster on Saturday, March 26, 2022. Earlier, the same project had suffered disaster in October 2019.[i]

The penstock pipe that takes water at high flow rates and speed from the Umrangso dam to the hydropower house burst during early hours of Saturday in Assam’s Dima Hasao (earlier called North Cachar Hill) district. A large portion of the Kopili Hydro Electric Plant was also inundated.[ii] At least three employees of the North Eastern Electric Power Corporation Limited (NEEPCO) who were present at the site were killed in the mishap.

Dam Floods & Embankment Breaches in South West Monsoon 2020

Improper operations of dams, disasters related to dams and hydro projects and breaching of embankments have been aggravating flood disasters during every monsoon. There have been several such incidents during South West Monsoon 2020, taking heavy toll on people and property which could have been avoided or impacts reduced in many cases with proper dam operations and proper maintenance of the embankments. This compilation attempts to put together all such instances when avoidable flood disasters were created by improper operation of dams and breaching of embankments in the south west monsoon 2020.

DRP News Bulletin 28 Oct 2019: Growing opposition to Large Hydro Projects

As can be seen from the news reports from Jammu & Kashmir, Assam, Arunchal Pradesh, Karnataka, among others, the opposition to Large Hydro Projects and Big Dam is growing all over India. These projects are neither economically viable, nor Socially-environmentally sustainable. There are much better options exist and hope the governments takes informed, democratic decisions. Going by the agenda and minutes of the recent Expert Appraisal Committee on River Valley Projects and other decisions, this hope seems far fetched at the moment.

Major disaster at Kopili Dam of NEEPCO in Assam in 2019

The 275 MW Kopili Dam Power House of NEEPCO (North Eastern Electric Power Corporation Limited, a Union Ministry of Power Underaking) in Assam suffered major disaster on Oct 7, 2019. The penstock pipe that takes water from the Umrangso dam to the hydropower house burst during early hours in Assam’s Dima Hasao (earlier called North Cachar Hill) district, and massive quantity of water erupted, a lot of it entered the power house, where four employees of NEEPCO are feared to have been trapped/ washed away[i]. A large portion of the Kopili Hydro Electric Plant was also inundated and a temporary bridge was also washed away[ii]. Some videos of the situation are also available.[iii] Continue reading “Major disaster at Kopili Dam of NEEPCO in Assam in 2019”

As this report narrates, a great volunteer effort is underway in Mumbai to clean up Mithi river. What they have achieved is just about 350 m of clean river, after labouring over weekends for several months. But this is such a daunting task to even venture to start. They have not only started, but made visible progress. Let us hope it will achieve all its objectives.

DRP News Bulletin 28 January 2019: Climate Change Poses Multiple Threats to India: Does Our Governance Care?

This week multiple reports warned of how India is already facing climate change impacts, how the groundwater, India’s water lifeline could be under threat under climate change, how India’s monsoon, the other water lifeline of India is under threat.

In fact, we should be bracing up for the drought that the summer will bring, but as yet there is no signs of any preparedness or plans.

The Dam floods in Indonesia and the Brazil’s disaster due to breach of mine tailings dam should be additional warnings, but our Dam Safety Bill that is before the Parliament does not recognise either of them.

The World wetlands day 2019 later this week has slogan of: “We are not powerless against climate Change… stop draining wetlands”, connecting climate change and wetlands. But the news from Indian wetlands governance is scary.

The day before the World Wetlands Day the Vote on Accounts will be presented before the Parliament as full budget cannot be presented in light of forthcoming Parliament elections. But is there any hope that either the Budget or the elections will deal with the climate change or the environment issue with any sense of seriousness?

The iconic Ardh Kumbh event is going on, but the govt has paid no attention to the fast by Swami Atmabodhanand, even after the death of Prof GD Agarwal for the same cause of Ganga.

Dam Floods 2018: Assam, Himachal; Making Dam Operators Accountable

ASSAM: NEEPCO a repeat offender? On July 27, 2018 sudden release of water from NEEPCO’s Doyang Hydropower Electric Project (HEP), located in Wokha district, Nagaland led to flood disaster[1], submerging[2] about 36 villages in Golaghat a district in Upper Assam. According to Rony Rajkumar, project officer of the Golaghat district disaster management authority, around 5,575 people were affected by the deluge which damaged 887.9 ha of crop.

Earlier, on July 11, 2018, reviewing the severe flood situation Lakhimpur Assam, the Chief Minister (CM) Sarbananda Sonowal strongly warned[3] the state-owned power utility NEEPCO not to release water from its Ranganadi dam without warning like previous years.

DRP News Bulletin 6 August 2018 (2018 is Deficient Monsoon for Lakhs of Farmers)

(Feature Image: IMD Sub-Division wise Weekly Rainfall Map 26 July – 1 Aug. 2018)

Amid news of monsoon being normal, farmers in several parts in the country have started facing irrigation water problems affecting sowing of Kharif crops. Apart from, insufficient rainfall, mismanagement of water resources is turning the situation grim for them.  

As per reports, water levels in Bhakra and Pong dams in Himachal has plunged to lowest in decades. As a result dam authority has issued advisory to lakhs of farmers in Haryana, Punjab and Rajasthan to use water judiciously. Some official also said that the beneficiary states lacks efficient water management practices which is making the situation tough for them.

The Sri Ram Sagar Project in Telangana has no irrigation water. As per state water minister, a Rs. 1100 crore work was going on to renovate the dam. Meanwhile farmers of about 24 villages have started protest demanding irrigation water form SRSP for their standing crops. Given the tense situation, the State Govt has deployed heavy police forces to control farmers agitation.

At the same time, farmers in North Gujarat farmers have lost 40% of sown crops particularly in Ahmedabad, Morbi and Surendranagar. Non availability of Narmada waters have added to the problems. It is worth to mention that mismanagement of water during past four months in Narmada dam by the authority, has worsened the plight of farmers. Meanwhile, there are reports of furious Surendranagar farmers themselves opening the dam gates going against authority.

Similarly, lack of rainfall in Beed district which is part of Marathwada in Maharashtra has affected the rural population badly. In fact, the rainfall situation in a fourth of India, including Bihar and Uttar Pradesh, was in stark contrast to the rest of the country. Overall, the southwest monsoon in 2018 was only 2 % below normal by July, 27.

The southwest monsoon in Bihar was almost 40 % below normal till July 27 and the state was set to be formally declared ‘drought-hit’. It is worth to mention that the monsoon scenario seems less than reassuring, based on Skymet latest forecast and reading between the lines of IMD Aug. 3, press release.

Comments on Scoping Clearance Application of Panyor HEP on Ranganadi River in Arunachal Pradesh

The Arunachal Pradesh government has signed a MoU with Panyor Hydro Power Private Limited, a company based in Hyderabad to construct the Panyor hydro electric project. This will be the second hydroelectric project coming up on the Panyor River which is also known as Ranganadi in the downstream. This project with 80 (2x40MW) MW installed capacity is to be considered for ToR clearance in the 69th meeting of EAC to be held on 11-12 November, 2013.

Salient Features Panyor Hydropower project will be located a Lemma, a village five km upstream of the Yazali town in Lower Subansiri district. The proposed project is 12 km upstream of the Ranganadi dam Stage II with a surface power house on the left bank of the river and a 108 m high concrete gravity dam. This reservoir will cover 7.5 km of the river length. The catchment area of this dam is 1315.50 sq km. The tail race channel will be 300 m long. Total area required for the project is 390 ha. Out of this 42 ha is river area, 25 ha is reserve forest and 323 ha is private land. The total estimated cost of this project is Rs 820 crores which imply that per megawatt cost is Rs 10.25 crores.

First Wave of Flash Flood on June 14, 2008 near N Lakhimpur town, due to excess water released from Ranganadi HEP without prior warning

Critical Issues It was surprising to see that even though the project has been on EAC agenda for ToR clearance MoEF website does not have the complete documents for this project. The PFR document of the project was not opening up in the website. Going through the Form I of the project we found several issues which need to be highlighted.

Downstream impacts In regard of the project on the Panyor river it is very important to remember that the catastrophic downstream impacts of hydropower dams in Arunachal, which has been a subject of much debate in Assam, with specific issues raised against the existing 405 MW HEP on Ranganadi. The release of water from the Ranganadi dam on June 14, 2008 had led to flash floods in a vast area and catastrophic devastation in the downstream. The Ranganadi dam is having severe downstream impacts not only in the Ranganadi valley, but also in the Dikrong valley since water from this dam is released in Dikrong or Pare River through an 8.5 km long diversion tunnel. Now construction of another dam on the same river which needs serious analysis since the Form I (p 45) states “Downstream impact on water, land, human environment due to drying up of the river at least 10 km downstream of the dam.”

The drying of the river for at least 10 km downstream of the proposed dam also need to seriously examined keeping in mind the reservoir spread of the Ranganadi stage I project.

Not a single village affected and no rehabilitation? Form I (p 33) states that not a single village would be affected and no rehabilitation needs to be done, which seems doubtful. The document at the beginning states that the project is located near Lemma village. It also suggests for socio-economic impacts where it mentioned about project affected families. These are serious contradictory issues within the same report and the developer should be asked to resolve this.

Environment Flow contradictory The Form I provides contradictory information regarding environment flow. On the last page, the document states “A scientific study shall be done to assess the downstream requirement of water to decide minimum assured release of water (Environmental Flows) for maintaining the aquatic ecology and water quality of river.” But on page 33 in the section 2.7 the document states that environment flow will be 3 cumecs.

Important aspects left out from scoping of EIA study In the scoping for EIA/EMP study there are several important aspect which the Form I has made no mention at all. These include:

1. Impacts of excavation and mining

2. Impact of the project on landslide and other disaster potential of the area and region.

3. Disaster management plan considering the previous flash flood event in June 2008.

4. Impacts of climate change and impacts of the project on local climate

5. Options assessment including potential of micro hydro (below 1 MW capacity)  projects. The project will submerge a huge 312 ha of land. The PP (Project Proponent) should look into the options for run of river project rather than a dam with such huge submergence.

Wrong answers given in Form 1 In case of some of the information given in the Form 1, it seems wrong and the PP should be asked to correct it. For example (this is not exhaustive list):

1. In case of point 1.26 (p 11), in response to question “Long-term dismantling or decommissioning or restoration works?”, the Form says “No”. This is clearly wrong. After the useful life of the dam, it will need to be decommissioned and this has to be part of the EIA and TOR.

2. Similarly answer to question 1.27 (“Ongoing activity during decommissioning which could have an impact on the environment?”) is wrongly given as No.

3. In para 1.2 (p 6) there is no mention of land requirement for mining material for the project like sand, gravel, boulders, etc.

4. Para 2.2 (p 12) how much water will be used (KLD) or source is not given.

5. Para 2.3, in answer to minerals No is given, where as the project will require sand, clay, gravel, boulders, etc.

6. In response to Para 2.7, the impact of project on aquatic biodiversity, including fisheries should have been mentioned.

7. In response to Para 3.1 use of explosives is admitted. However, it should be told to PP to minimize the use of explosives considering the impact of them on increased landslides and other disasters.

8. In response to Para 3.3 the PP should have mentioned the impact of project on the people who also use the forests, rivers, get affected by other aspects including destruction of biodiversity including fisheries upstream and downstream.

9. In para 4.2 (p 16) and elsewhere, estimate of 1000 populations for “400 technical and labour staff” is clearly wrong. Also estimate of 200 labour vs 150 technical staff also do not seem correct.

10. Para 4.3 should also include the remains of explosives among hazardous waste.

11. Para 5.8 (p 19) answer (Q: Emissions from any other sources) No is clearly wrong, the reservoir covering 312 ha will certainly emit methane needs to be assessed.

12. In para 8.3 (p 22) and point 12 under environmental sensitivity (p 25-6) the vulnerability due to floods and landslides such others also need to be mentioned and response to them included.

13. The whole document keeps mentioning 25 ha forest land without inclusion of the community managed forest land in Arunachal Pradesh. This is clearly wrong information.

14. Under point 3 in on Environmental sensitivity (p 24) in response to “Areas used by protected, important or sensitive species of flora or fauna for breeding, nesting, foraging, resting, over wintering, migration”, it is not sufficient to investigate with forest dept, as the response says, since there are several aspects here (e.g. aquatic biodiversity) that are beyond the domain of forest department.

Cumulative Impact Assessment The information given in para 9.4 (p 24) is clearly wrong. There are at least eleven hydropower projects at various stages in the combined Ranganadi-Dikrong basin, including one operating, one under construction, three TOR approvals given and five additional MoA signed (in addition to the proposed project), see details below:

1. 405 MW Ranganadi HEP (Existing, transferring water from Ranganadi to Dikrong)

2. 110 MW Pare HEP (under construction)

3. 60 MW Par HEP on Dikrong (TOR approved by EAC on 8/9/2012)

4. 60 MW Dardu HEP on Dikrong (TOR approved by EAC on 8/9/2012)

5. 66 MW Turu HEP on Dikrong (TOR approved by EAC on 8/9/2012)

6. 25 MW Adum (Upper) Panyor HEP: Upfront premium and application fee of Rs 11.05 lakhs received by Arunachal Pradesh government from BSS Arunachal Energy Development Pvt. Ltd. (on 10/03/2010)[1]

7. 21 MW Panyor Lepa Middle HEP: Upfront premium nad processing fee of Rs 9.4 lakhs received by Arunachal Pradesh Government from JMD Power Solutions Pvt, New Delhi (on 27/08/2010)

8. 25 MW Papumpam HEP: allotted to: Meena Entrade and Engineering Pvt. Ltd. Naharlagun, AP. on 19/08/2008[2]

9.  15 MW Papum HEP: allotted to Patel Tours and Travels (Mumbai) on Dec 12, 2008

10. 12 MW Poma HEP: allotted to Patel Tours and Travels (Mumbai) on Dec 12, 2008

Hence a credible basin study is required BEFORE any more (including Panyor) projects are considered in Ranganadi-Dikrong basin.

Costly Project Per MW cost of this project will be Rs 10.25 crores according to current estimates. This will be costly affair considering that per MW cost of solar PV project would be lower than this.

Until the above issues are resolved, the project should not be considered for Scoping clearance.

Annexure: Panchayati Raj Institutions question the project

PRIs question Govt on power project

ITANAGAR, July 11: Panchayat leaders of Pistana and Yachuli circles of Lower Subansiri district have voiced their protest against coming up of Panyor Hydro Electric Project, which they claimed was ‘kept secret’ from the public.

In a representation to the Chief Secretary yesterday, the PR leaders led by Zilla Parishad Chairperson Likha Tongum said that  Panyor Hydro Electric Project came to light when M/S Raajratna Energy Holdings Private Ltd of Shimla, started surveying and investigation works in the area. They urged the Chief Secretary to cancel the MoA signed with the private company immediately in the interest of local sentiments.

To the surprise of the people of the area, MoA to this regard was already signed between the govt and the company on February 25 last for implementation of the 80 MW project on BOOT basis for which an amount of Rs 80 lakhs (at Rs 1 lakh per MW) as processing fees was already paid in the name of the Secretary Power, Govt of AP. The grass-root leaders alleged that the whole process was carried out secretly and kept under wraps.

They leaders further came down heavily on the agency for “totally undermining the project affected panchayats”.  

If any agency wants to tap the natural resources available, they have to take the confidence of at least the local panchayat leaders, which is a normal procedure in a democratic setup, the leaders said.

“The local panchayats are the sole custodian and owner of natural resources in the region since time immemorial,” the leaders said and have decided to protest against the execution of the project.
