   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. 

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 women at village Salna wherein around 34 women from village got benefitted and have started activity of their own. Similar Training was imparted among women SHG`s at Relocation site at Daswana previously. The SHGs have completed knitting sweaters as per requirement and the sweaters have been purchased by THDCIL at Rs. 450 per piece. The sweaters are given to the needy children studying in Primary School. The activity has since become rotational due to which more demand are being received by Project. THDCIL, considering the demand, have procured 2 Knitting Machines and given to SHGs at Haat & El Dana. The Trainer, as & when required for training, is deputed by Project.   

·        The Public Information Center (PIC) established at Gulabkoti has been equipped with computers. A trainer has been engaged by Project & basic training on Computers is being imparted among youths of Gulabkoti & nearby village. The local youths interested in computers are being imparted training from time to time. Till date around 12 Youths have been benefitted.   

·        Various community development programs in affected villages are in progress that comprise of; Infrastructure activities, drinking water supply, distribution of generators, school bags, School 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. A Cumulative Expenditure of Rs.37.14 Lacs stand incurred till academic year 2016-17.

 

Infrastructure works:

All four bridges, approach roads to bridges, colony area, Dam site and Power house site, have been completed.          

Most of the infrastructure development works have been completed.  

Supply and installation of equipment of dam site sub-station has been completed and sub-station has been handed over to THDCIL. Installation of equipment in Power House Sub-station building by UPCL has been completed.

8.0 ISSUES TO BE RESOLVED:  

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

·      Villagers near Dam site were hindering the works every now and then. Accordingly, THDCIL submitted a petition in the Honb'le District Court on 15.06.2015 for relief. The decision was given by the court in THDCIL's favour on 30.08.2016 to restrain the local villagers from creating any obstruction.

·      Even after Court's decision, works at Dam site now again stopped by the local villagers from 13th May'17 evening till date to press their various new demands of employment, school bus, construction of village road etc. The stoppage of works severely affected the Dam site works.

·      Discussions with villagers were held by THDCIL officials on 15.05.17. Again meeting was held by THDCIL with villagers in presence of SDM, Joshimath on 31.05.2017. THDCIL requested DM, Chamoli on 16.05.17 and 29.05.17 for intervention for early resolution of the issue. No solution has been achieved and stoppage is still continued. THDCIL vide letter dtd. 01.06.2017 requested Circle Officer, Police Deptt., Joshimath to lodge FIR in this regard.     

·      GoUK may be requested for intervention for early resumption of works.  

8.2  Cash Crunch faced by Contractor:

·     The project works are almost in standstill position due to financial problems of the civil works contractor M/s HCC. The works are moving towards demobilization stage due to inadequate deployment of resources by M/s HCC. Subsequent to approval of the Board for extending financial assistance, part gap funding support was provided to the contractor against BG in phases to improve the resource deployment at various work fronts. The contractor is facing problem in arranging even Bank Guarantees for further gap funding support, therefore this part financial support against BG provided to HCC could not brought the project on track.  

·        Due to cash crunch faced, Contractor (M/S HCC) is not able to augment required resources, required spares for equipment and timely payments to PRWs severely affecting work progress.
