  6.0   PRELIMINARY PROJECT WORKS:

Investigations:

·        Geological investigations at all locations of the project and various required studies have been completed.

 

Rehabilitation & Resettlement :

THDC India Ltd has formulated a Rehabilitation & Resettlement policy (R&R Policy) for the Vishnugad Pipalkoti Hydro Electric Project. The Policy is based on the National Rehabilitation & Resettlement Policy 2007 (NRRP-2007) incorporating the better features considering the World Bank Guidelines on Involuntary Settlement and needs & expectations of the stakeholders.

 

The Policy addresses the R&R issues through proactive approach and appropriate Planning on Land Acquisition. Besides disbursement of compensation by Special Land Acquisition Officer (SLAO), the Policy envisages provisions of grants and other benefits considering the categories and the Entitlements.

 

 

For effective implementation of R&R policy, Rehabilitation Action Plan (RAP) has been formulated so that after reasonable transition period, the affected families improve, at least regain their previous standard of living, earning capacity and production levels.

 

   Land Acquisition:

·        A total of 132.029 Ha. of Private land and forest land has been acquired for VPHEP of which 31.639 Ha is Private Land and 100.39 Ha is Forest Land.

 

·        The Implementation of Rehabilitation Action Plan (RAP) and R&R related Activities are presently under Progress. The Project has taken over the possession of requisite 31.639 Ha. of Private Land across 7 Villages. Around 94% of Compensation amount has been disbursed by Special Land Acquisition Officer (SLAO). Of the 07 Affected Villages, only one village i.e. Haat is getting relocated.

 

·        In village Haat 20.337 Ha land has been acquired. Through District Administration 83 residents households have been identified. 77 families have signed agreement with THDCIL, 77 have constructed houses and 72 have shifted. 55 families have demolished their houses.

 

·        The process of extending the Special Package among "Non-Residents" House Owners as per eligibility is underway. District Administration has verified the list of 50 Non-Resident HSO's. The registration has been completed for 28 HSO's & 26 Houses demolished.

 

·        Settlement with all 09 ST Families reached at. Of the 09 families, 02 Families have already signed agreement & an amount INR 01 Million disbursed as well. Families have shifted.

 

·        Agreement stands signed with another 07 families & 1st Installment of INR 03 Lacs of the INR 01 Million has also been released. ST Families have already purchased 08 Naali of land for their relocation. Development of Area including providing necessary infrastructure facilities at relocation site has been completed by THDCIL. Construction of houses by 3 ST Families is under Progress.

 

Social Responsibilities:

·        Various skills up-gradation & income restoration programs are being undertaken for livelihood promotion and better employment opportunities for the Project Affected People (PAP). Various Trainings comprising of dairy farming, vermin composing, cutting & tailoring, knitting, kroiler management, Napier grass production, Production of cash crops, promotion of Tulsi for herbal medicines, horticulture activities, bee keeping etc. have been imparted to PAPs. Apart from this, Vocational Trainings in hotel management, skill enhancement activities, etc. are also undertaken, in coordination with various institutes like GMR Foundation, Dr. Reddy Foundation, and Industrial Training Institutes in nearby areas.

 

·        The training on knitting & tailoring has already been imparted among the women from Villages; Tapon, Salna, El Dana & Daswana. Around 113 & 67 Females have been benefitted from Training on Tailoring & Knitting respectively from said villages.  The Females have started activity of their own. THDCIL purchases the sweaters & payment being disbursed at Rs. 450 per piece. THDCIL distributes the sweaters to the needy children studying in Primary School. THDCIL has purchased 2 Knitting Machines and given to SHGs at Haat & El Dana as well. The Trainer as & when required for training is deputed by Project. The NGO also intervenes from time to time. The knitting & tailoring activity has since become rotational due to which the Females in Project Area are getting independent financially.

 

·        After completion of the 3 Days Training on Promoting Oyster Mushroom cultivation at Dehradun during June, 2017 by 8 Women PAPs from village Guniyala, Haat & Jaisal, the PAPs have cultivated good quantity of Oyster Mushrooms for themselves. The Extra Quantity so cultivated have been distributed among other PAPs of same village in order to spread & boost the activity. The NGO intervenes as & when assistance by PAPs is required. THDCIL has also proposed to give Tool Kit & other requisite equipments for promotion of Oyster Mushroom cultivation among PAPs. Apart from above, other areas from where PAPs have been generating income are Dairy Development, Backyard Poultry, Agricultural activities etc. The above activities are a tool under employment generation / livelihood Programme.

 

·        The Public Information Center (PIC) established at Gulabkoti is since functional. The PIC is equipped with computers. The youths from Gulabkoti & nearby villages attend the centre to build confidence towards working on Computers. Around 12 Youths have been benefitted till date.

 

·        Various community development programs in affected villages are in progress that comprise of; Infrastructure activities, drinking water supply, distribution of generators, school bags, Uniforms, Sweaters, Solar Lights etc.

 

·        The Scholarship Policy of VPHEP is in the process of implementation ever since its inception in 2010. Till date, around 924 students that include 506 Girls from Project Affected Villages have been benefitted from the said Scheme.

8.0 ISSUES TO BE RESOLVED:

 

8.1    Maintaining Law and Order at Vishnugad Pipalkoti Hydro Electric Project (444MW), Distt. Chamoli.

 

·        The project progress has been severely impacted by hindrances created by local people. Intermittent Hindrances by local villagers still continue and work progress is getting badly affected due to these hindrances and subsequent recurring demobilization of resources. Recently, since 29.09.2017 two families of Harsari village blocked the approach road to Tunnel Boring machine platform and Power House associated works area leading to complete halt of works in these areas. THDCIL and World Bank officials also held discussions with villagers but they were not ready to open the road and were asking THDCIL to acquire their land on their terms and conditions which were beyond R&R policy though their land is not required by THDCIL.

 

·        The issue was brought to the notice of Distt. Administration, Chief Secretary, GoUK, Hon'ble Chief Minister, GoUK and Secretary (Power), GoI. After raising the issue at these levels, the work could be resumed in the afternoon of 31.10.2017.

 

·        The strong support of District Administration is required to promptly tackle such hindrances.

 

8.2  Cash Crunch faced by Contractor:

·        Subsequent to infusion of Interest Bearing Additional Working Capital Advance (against Performance Bank Guarantees) of Rs. 37.5 Crs during June to Oct.'17, some resource augmentation was done by M/s HCC in the phased manner.

 

·        Rs. 15 Crs. only has been released further against BG provided by M/s HCC in mid Oct.'17.

 

·        M/s HCC had assured to provide Bank Guarantees to restore PBG by Sep-17, based on receipt of funds under NITI Aayog circular dtd 05.09.16. However, M/s HCC has not been able to submit the BG and is expected to submit the same after increase of limit by its bankers. THDCIL vide letter dtd 16.10.17 has intimated MoP regarding delay in release of increased BG limit of M/s HCC (Rs 1550 Crs. sanctioned in Dec-16) by various PSU Banks and delay in release of 75% arbitral award amount by some PSUs.

 

·        Over all progress on both the projects is not at required pace due to fund crisis.
