Patel Chief Engineer (In charge) and Additional Secretary (Kalpasar) welcomed the members, invitees and officials on behalf of the Chairman and the Kalpasar Department and with the consent of the Chairman; he proceeded with the agenda of the meeting. Agenda Item No.1: Minutes of the 2nd Meeting of the Expert

Advisory Group (EAG) held at Ahmedabad on 26th – 27th July, 2006.

The minutes of the 2nd EAG meeting, which was already circulated to all EAG members was confirmed unanimously. Agenda Item No.2: Action taken after 2nd EAG Meeting

The Action Taken Report (ATR), as prepared by Kalpasar

Department on the decisions taken in the 2nd EAG meeting, was accepted.

Agenda Item No.3: Strategic Paper for Kalpasar Project. Strategic paper for Kalpasar Project as prepared by Prof. Asit Biswas and Mr. Sutmuller, members was taken up for discussion. Mr. Sutmuller made a presentation on some of the important issues of strategic paper. The draft strategic paper was circulated earlier on which the Chairman, EAG had made certain suggestions on 15.12.2006. The revised strategic paper should include the suggestions made by the Chairman, EAG. As the strategic paper intend to decide the road map of Kalpasar Project and how to proceed with Kalpasar Project, all EAG members, consultants and Kalpasar Department Officials took keen interest during the discussion of strategic paper.

It was decided that the following important points need to be considered while revising the strategic paper.

• In the revised PERT/ bar chart, the project construction activity is required to be commenced before expiry of three years from the environment and forest clearance from MOEF as per present Government Of India’s guidelines.

• The activities, which are to be looked after by PMDC in the estimated cost of US$52.00 million, is required to be clubbed in separate group.

• In the BAR Chart, the commencement of the work is shown in the year 2016. Chairman EAG advised to compress the earlier activities on realistic basis in such a way that the commencement in a phased manner is possible by year 2009-10 or within 3 years from environment clearance, whichever is earlier.

• The PERT / CPM chart, if prepared in place of Bar chart, will be more useful for the purpose of monitoring and recasting of the activities.

• Year wise breakup of US$52.00 million is required for deciding the budgetary financial provision for each year in advance.

• Need to think of prioritizing the revenue generating areas and high capital-intensive and difficult areas at a later stage while formulating the phasing of the project.

• The sequence of activities prevalent in the Narmada and Water Resources Department of Gujarat for any project is (i) Obtaining administrative approval (ii) finalization of all the design aspects (iii) Preparation of detailed estimates (iv) Initiation of tender proceeding and finally (v). Commencement of actual construction activity. These aspects may be considered in revised PERT/ BAR chart.

• As per the prevailing procedure adopted for any project, the bid documents are invited in two parts, Technical bid and Price bid submitted in two separate sealed covers. The evaluation of the bids and the award of the Contract are generally completed in 120 to 150 days from date of invitation of bids. In the revised bar chart these aspects may be considered.

• As this is a unique project, no bidder in the world possesses the whole required expertise to finalize the design and structural components of the project. Hence, it will be more appropriate that PMDC, in consultation with Kalpasar Department, to finalize the design, drawing and estimates for the project and also finalize the estimates for various components and suggest the areas that require private participation and the areas that require government budgetary provision.

• The suggestions and views of the Shri B. N. Navalawala, Chairman EAG and Shri N. B. Desai, Shri G. L. Java and Shri D. M. Pancholi, Consultants given during discussions may also be considered.

The chairman, EAG requested Mr. A. M. Sutmuller to consider all the points suggested during the meeting and accordingly to revise the strategic paper for circulation to EAG members and Kalpasar Department within two or three months as the next EAG meeting is likely to be held in first week of June, 2007 so that the Strategic paper can be finalized and submitted to the Government of Gujarat at the highest level for consideration. Agenda Item No. 4: Project Management and Design

Consultant. The agenda item of PMDC was discussed in the last meeting and EAG had approved the Expression of Interest including the minimum eligible criteria like scope, responsibility etc.for PMDC. Accordingly, Superintending Engineer, Kalpasar Technical Cell invited Global Tenders with wide publicity on 26.09.2006. The last date for the receipt of the bids was 24.11.2006.

Chaudhary presented his report in the EAG meeting. Dr. Chaudhary narrated the issues in preparation of Base map, soil survey by Auger bore hole, installation of piezometers for Ground Water Measurement, trial pit for soil profile and five pilot projects each in different earmarked zones and land use planning. EAG suggested that Dr. T. N. Chaudhary should visit the site with Kalpasar Staff and thereafter identify the areas for soil investigation, ground water investigation and pilot studies on the base map. The Consultant should also justify the technical factors for the selection of sites and the number of pilot projects. The sites should be finalized in consultation with local farmers and in areas where irrigation command conditions similar to the Kalpasar project exist. Accordingly, the services of GERI, Vadodara for soil investigation, GWRDC for ground water investigations and the Agriculture Universities for agriculture purposes can be utilized or alternative can also be worked out by the consultant. The Consultant should suggest the works to be executed by these institutes and the tentative time and cost involved. . The EAG suggested that Dr. T. N. Chaudhary should prepare a comprehensive report covering all the above points as well as keeping in view the format of Detailed Bankable Report and submit the report before next EAG meeting i.e. before June 2007. Agenda Item No. 6 & 7: (a) Bathymetry and Offshore data collection and

(b) Report of Dr. S. Z. Qasim, Consultant for Bathymetry and

Oceanography, Sea bed and Marine Study/Survey.

Kalpasar Department presented the actions taken after 2nd EAG meeting for convincing NIOT to commence the detailed survey work in the 2 Km wide corridor area and taking the services of Dr. S.Z. Qasim, as a consultant for Kalpasar Project. As NIOT is still not coming up to carry out the work, even after the persuasion at various levels, the EAG opined that other alternatives like giving this work to NIO, Goa or carrying out through global tendering should be considered and finalized in consultation with Chairman EAG before next EAG meeting. The Bathymetric survey work at shallow depths could not be executed by NIOT as it was not technically feasible through ship. They have initially suggested utilizing Lidar technologies. Latter, NIOT has suggested the name of IIC Technology Pvt. Ltd, Hyderabad for the same. To find the alternatives to the shallow depth survey, Shri Rajesh Alla, President and CEO, IIC, Technology, Hyderabad, and Mr.

9

Peter Hobson, MD, Admiraty Surveys, UK were invited to make a presentation. In the presentation, the issue of the accuracy, time factor, estimates and other involving factors were discussed. EAG advised to take the services of ONGC/WAPCOS/CWPRS/ Indian Navy/NIO and suggested that they should also be immediately contacted so that an alternative to NIOT can be sought of and the Bathymetric survey work at shallow depths can be completed at the earliest. If the above Central Government Agencies are not ready to take up this work, then Global Tenders should be invited. EAG has accepted the report of Dr. S.Z. Qasim, consultant on “Bathymetry, Oceanography, Seabed and Marine study/survey”. Regarding the future work of bathymetry and oceanography, EAG suggested to utilize the services of Shri B.N. Desai, Ex. Director, NIO and Dr. Mani as Dr. S.Z. Qasim, Consultant can not spare time to Kalpasar due to his age and other assignments. Agenda Item No. 8: NEERI Proposal for scoping of

Environmental Impact assessment /

Social Impact Assessment. EAG recommended to award the work of EIA/SIA scoping to NEERI, Nagpur. Accordingly, Government of Gujarat has accepted the lowest financial and technical proposal of NEERI amounting to Rs.47.14 lakhs. Dr. S.R. Wate, Dy. Director, NEERI presented the work to be carried out by NEERI to the EAG members. NEERI’s proposal for scoping mainly covers (a) content (b) work to be undertaken, (c) payment terms EAG has accepted the methodology suggested by NEERI for scoping. They have also suggested including (a) activities that give positive impacts in addition to the negative impacts. (b) To integrate all the activities in the scoping phase. (c) Tsunami effect on the fresh water (d) rehabilitation (e) salt pan area etc. As EIA/SIA studies are of vital importance for the Kalpasar Project, the EAG suggested taking up the scoping work immediately and submitting the progress report in the next EAG meeting to be held on first week of June, 2007. The representative of NEERI accepted this and assured that all the above points would be covered in the scoping.

Agenda Item No. 9: Report of Dr. Z. S. Tarapore, Consultant on Regime Modelling

The issue of CWPRS was also discussed. It was apprised to EAG that CWPRS, as per their letter dated 28.12.2006,has stated that “Presently, Coastal and River Group at CWPRS have been actively busy in works related to port development, coastal protection works, river water resources projects, development of special economics zone, water cooling for thermal power projects, flooding etc. and this team may not be readily available for Kalpasar Project for a very long period” Therefore there is no progress in CWPRS’s work and giving the work of Regime modelling to CWPRS is not possible. EAG has advised that the regime modeling should be the part of PMDC and a separate study by inviting global tenders is at present not necessary. Dr. Tarapore, appointed as consultant for Regime Modelling, has prepared the report on ‘Model study for Kalpasar Project”. Dr Tarapore made the presentation to the EAG. After Dr. Tarapore’s presentation. EAG has accepted Dr. Z. S. Tarapore’s report. EAG has prioritized various modeling studies in consultation with Dr. Z. S. Tarapore as shown under: (I) High priority

(a) Mathematical Modelling

• One-Dimensional modelling of potential flooding problems in

lower Narmada downstream SSP and Sabarmati and Mahi estuaries when flood impinges on FRL.

• Two-Dimensional Mathematical Modelling of Gulf for study of: (1) Tidal reflection with and without tidal power operation. (2) Morphological changes downstream of dam. (3) Impact on Malacca bank. (4) Impact on generation of power. (5) Closure studies.

• Three - Dimensional mathematical modelling of mixing in reservoir during initial years including effects of sluicing / pumping model to study duration required to make water potable / suitable for irrigation.

(b) Physical Modelling

• Model of Narmada mouth near Luhara point to study optimal

alignment of closure dam and location of spillway • Laboratory testing of erodibility of soils in mud flats.

(c) Field Studies Carried Out

11

• NIOT commissioned to carry out bathymetry over the corridor of 10 Km. for selecting alignment of dam - need to extend survey for bathymetry of Gulf to be modeled.

• NIOT carried out current observations at 7 locations in a short 7 Km. reach - need to carry out more extensive (in space) observations in consultation with the modelers

• Coastal tide observations at 9 sites are adequate- needs supplementing by a deep sea recorder at about Lat. 20 degree –

• Water samples collected are small volume - inadequate for grain size analysis. Large volumes (pumped samplers) necessary

• Sea bed samples at 115 locations along dam corridor - needs extension over entire Gulf.

(II) Low Priority

(a) Mathematical Modelling

• One-Dimensional modelling of daily flows from Narmada in to Kalpasar.

(b) Physical Modelling

• Spillway discharge characteristics. • Design of lock filling system for two way gradients - FRL to

LWOST and HWOST to LLWL (including salt intrusion).

EAG suggested that Dr. Tarapore, consultant should now work out i).what type of data should be given to PMDC for each modeling study. ii). which data are available. iii).How the other required data from other institutes satisfy the requirements. iv).From now onwards what data are to be taken, and at location, frequency, its type and methodology and who can help for this data collection? Dr. Tarapore, consultant may be requested to prepare a report before the next EAG meeting. Agenda Item No.10: Report of Dr. S. R. Gandhi and Mr. D. M.

Pancholi, Consultants on Geo technical investigation.

Dr. S.R.Gandhi, Prof. IIT. Chennai, Dr. Adimoolam Boominathan, Assistant Prof.IIT, Chennai and Mr.D.M.Pancholi, Retd. Superintending

12

Engineer, C.D.O.Gandhinagar have been appointed as consultants on the advice of the EAG. They have submitted a report on Geo-technical investigation studies for the Kalpasar Project. The Consultants made presentations to EAG. Following are the salient points.

� There are in all about 9 major faults in the area aligned mostly along NNW-SSE direction. Several other potentially active tectonic structures and interpreted to be recently active are along NNE-SSW and N-S directions.

� The entire area could be classified into three major structural domains.

� Northern neo-tectonically active domain � Southern terrain with major subsurface faults � Central “dormant” domain

� This central domain falls to the north of Main Dam Axis alignment and its north up to 1500 m.

� NIOT studies show the presence of other sediments like sand, silt, clay, hard rock etc.

� Consultants are of the opinion that the central domain without any of the major structural disturbances is recommended for conducting a detailed survey including geotechnical surveys in order to finalise the location of the dam axis as per the report of NIOT.

� However, following things are to be studied before coming to the final conclusion of the dam alignment.

� Density of various layers � Liquefaction/strain softening behaviour of soils � Shear wave velocity profile

� Hence consultants agreed with the recommendation of the earlier six specific studies to drill 10-12 bore holes on both Khambhat dam & Narmada closure respectively.

Consultants suggested 13 additional bore holes. They opined that the earlier drilling was done at such locations that do not give adequate geophysical/geotechnical information at vital locations. The locations of 13 nos. holes suggested are such that the additional information will provide the required results. Dr Gandhi stated that as per his experience it is difficult to envisage the time frame for drilling activities, which in real term starts only when the particular type of machineries, available with very few agencies, reach to the designated location. These types of machineries are very rarely free. The time to finish the drilling will be six months after actual drilling starts.

13

EAG has accepted the report of Dr. Gandhi and Mr. Pancholi. Looking to the importance of dam alignment and as stated by the consultants the limitation of bathymetry to decide geotechnical parameters of sub strata, EAG has accepted to carry out geotechnical investigation as suggested by consultants at 13 different locations after carrying out Geophysical Phase II survey . EAG recommended that consultants should prepare TOR, cost estimates, technical specifications, strategy and methodology to be adopted for geotechnical investigations. Consultants should also suggest the parameters for sampling, testing, preserving etc. They should also suggest the agencies that have carried out such work and time frame of the program required for the same. The Consultant should place the details in next EAG meeting. Agenda item No.11: Topographical survey work and GIS and

Data Base Management. SOI has earlier carried out Phase-I topographical survey work in 1:15000 scale with 0.50 m contour interval. EIA/SIA, Regime modelling, Sedimentation, Morphological, excessive flood and backwater effect studies, flood effect etc. are required to be carried out. The ground contours along the rivers will be required between 0 to 10 m contour surrounding the Kalpasar lake in the feasibility studies. Hence, in the last meeting, it was decided to carry out topographical survey work in rivers.. Brig. Shri Samudra of SOI made a presentation for carrying out this additional work. He mentioned the methodology to be adopted and the time to be required and stated that this work will require 3 to 4 years due to other important defence works on hand and shortage of staff. After discussions, the EAG recommended that this work should be carried out in phased manner as suggested in the agenda item. As per the opinion of consultants of Regime modelling, the contour interval of 0.5 m is not necessary throughout the river. Hence EAG advised that for speeding up of the work of topographic studies, the contour interval should be 0.5 m on 1:15000 scale from the river mouth up to 20 km from Kalpasar reservoir, 1.0m contour interval from 20 km to 50km and 2.0m contour interval from 50km onwards towards upstream side of the rivers. With this it will be possible to curtail the time. SOI has agreed to reduce the time and carry out work in phased manner as suggested by EAG. Bhaskaracharya Institute for Space Applications and Geo-informatics (BISAG) an Institute of Government of Gujarat, is carrying out works of various department like village maps, land uses, Population, road, water resources structures, railway, district boundaries, taluka boundary etc on GIS. As decided in the last EAG meeting, the topographical survey map received from SOI is digitized in Kalpasar

14

head office with guidance of BISAG engineers. The preliminary work carried out by BISAG is presented to the EAG by Dr. T.P. Singh, Director, BISAG. The EAG decided that the Chairman EAG may visit the BISAG for identifying their capabilities so that their services can be utilized for further work. Agenda Item No. 12: Report of Mr. K. D. Rathod and Mr. P. C.

Tyagi on Water Quality Impact Shri P.C. Tyagi, Ex. Chairman, CPCB and Shri K.D. Rathod, Ex. Member Secretary, GPCB have been appointed as consultants as per recommendation of EAG. They have prepared a report on water quality impact on Kalpasar. They presented a presentation before EAG regarding the same. Shri Rathod stated that impact of pollution and water quality of Kalpasar reservoir has been examined in six specific studies. However, the consultant also explained that the earlier studies show following limitations. Limitations of the study

• It is desk study & no field data with Kalpasar. • Data assumptions & uncertainties. • Available data inadequate for making decisions Sustainability of reservoir depends upon management of water quality and flow. The detailed field data base for water quality analysis is required for EIA/SIA, Environment clearance, Environment problems and mitigation planning and total sustainability of reservoir quality and quantity.

The Consultants in their report have suggested the following

points: • Parameters. • Location of sampling & flow measurement. • Frequency of sampling & flow measurement. • Methodology of sampling. • Laboratory procedure for analyzing samples. • Quantity – Flow measurement. • Diversion (bye pass drain) of waste waters. • List of laboratories approved by GPCB or CPCB. EAG has also advised that EIA/SIA study is very critical. The external funding agencies can take interest only if the present environmental and social problems have been analyzed, the mitigation methodology is decided, management of water inlet to Kalpasar reservoir and diversion to bye pass is properly studied and the scenario of pollution

15

from effluents of industries, urban effects etc., when the project is likely to be completed in 2020, are studied in detail.

The EAG accepted the report of Shri Rathod & Shri Tyagi on water quality impact on Kalpasar Project and suggested that Shri Rathod, consultant who is conversant with Gujarat effluents and pollution problem should visit the site with Kalpasar field staff and also visit GERI for utilizing their services for analyzing the water quality data. The Consultants should prepare the report and cover the above points as well as water quality and quantity analysis. Also, the Consultants should prepare the estimate of water quality/flow analysis and also give opinion regarding GERI’s capacity for this work. Agenda Item No.13: Water Availability of Kalpasar Reservoir-

views of Shri N.B.Desai & Shri G.L.Java, Consultants.

It was decided in the last EAG meeting for reassessment of water availability considering latest rainfall-runoff series by the prescribed Government procedure/methodology. They have suggested Shri N. B. Desai Ex Secretary N.W.R., W.S. & (K) Deptt. & Shri G. L. Java Ex. Secretary SSNNL as consultants. Shri Desai and Shri Java consultants have prepared the report and also made presentation to EAG. Some of the important tables are as under.

As per the earlier studies for availability of water assessment, following years data are considered.

The EAG accepted the reports of consultants and their analysis for water availability. The issue of water availability in Gujarat was discussed in depth. South & central Gujarat has average rainfall 800 mm-2000 mm. ,whereas water scarce Saurashtra region receives average annual rainfall 500 mm to 600 mm only. Per capita availability of water in Gujarat at present is 963 m3 per annum against the minimum requirement of 1000 m3/per capita/annum. It was explained to EAG members that available water resources are not equally distributed in Gujarat. South & central Gujarat region, having 24 % of geographical area, possesses 71.4 % of water resources, North Gujarat region, having 20 % of area, possesses 10.6 % of water resources, Saurashtra region, having 33 % of area, possesses 15.8 % of water resources and Kachchh region, having 23 % of area, possesses 2.2 % of water resources of the State. Earlier Government of Gujarat’s Irrigation Department used to adopt 75% dependability criteria for water resources project planning. However Central Water Commission, M.O.W.R.(Ministry of Water Resources) in year 1983, considered 50% dependability criteria for major & medium water resources projects in drought prone area in India.(Annex-1). Consequently, the Government of Gujarat, Narmada Water Resources Department took a conscious decision vide vernacular Resolution No. S-9890-1242-K2 Dated 1/8/1990(Annex-1) to adopt 50% dependability for all new major & medium water resources projects in the Saurashtra region. Saurashtra region is basically agricultural region and most of the major, medium & minor irrigation schemes are already implemented. Even after Sardar Sarovar Project only 15 lac hectare land will get irrigation benefit and 27 lac ha land will remain unirrigated. As per present planning, Kalpasar Project will irrigate Saurashtra region of Gujarat only. Hence the issue for adopting 50% or 75% dependability came up for discussion before the EAG. EAG also considered the rainfall, water- scarcity of Saurashtra & storage criteria while deciding the dependability. The live storage

18

envisaged of Kalpasar Project is 12247 Mm3 against availability of 10011 Mm3 @ 50% dependability & 5913 Mm3 @ 75% dependability of water resources. Therefore huge surplus reserve storage is available. Hence 50% dependability will be more useful to store extra water in good years. In view of above considerations and facts, the EAG decided to go along with the Government of Gujarat’s present policy to adopt 50% dependability criteria in Saurashtra region for irrigation planning of Kalpasar Project. They also agreed with the quantity of water available to Kalpasar as arrived by the consultants. Accordingly, the EAG considered 10011Mm3 water (50% dependability) for further studies. Also, the EAG requested the consultants for following points to study and place the results/findings of their study before next EAG. (i)Reallocation of available water for irrigation, domestic and

industrial purposes (ii)They should also examine & plan the irrigation command area with reference to: .

a) Protective irrigation, b) Drip & Sprinkler irrigation c) Special provision for socially & economically backward areas or

any other suitable irrigation pattern. d) The integration of existing projects, coastal tidal regulators,

check dams etc while planning for irrigation command. (iii) To examine availability of surplus water in South Gujarat &

alternative(s) to divert this water to Saurashtra and other area of Gujarat and feasibility to use Kalpasar reservoir as a tool for diversion storage.

Agenda Item No.14: Views of Dr. EAS Sarma, Consultant on Tidal Power.

Mr. H. L. Bajaj, Ex-chairman, Central Electricity Authority and presently Technical Member of Appellate Tribunal for Electricity, New Delhi, Mr. G.N. Mathur, CBIP.(Central Board of Irrigation and Power) , Mr. H.R.Sharma, Ex. Chairman, CEA. (Mauritius) and Dr.E.A.S.Sarma, Former Secretary, Ministry of Power, Govt.Of India were recommended by EAG for tidal power studies. EAG has also identified the areas for studies, which are as under.

• Feasibility of tidal power in Kalpasar, phasing of dam construction, single or double, or as suggested by Hydrocoop.

• Reasons and factors for non-implementation of tidal power projects in other countries.

19

• Future cost of thermal power considering alarming rise in cost of conventional fuel at global level and also its pollution effects on environment.

• Future demands of power in the State. • Cost economics of tidal power generation vis-à-vis thermal

power generation on the basis of 2010, 2025 & 2050. • Future orientation in regard to power demands, cost of power

generation etc. should be considered. • Other issues as decided by the EAG and Kalpasar Department,

including consideration of carbon credits for tidal power generation.

Mr. H. L. Bajaj, Ex-chairman, Central Electricity Authority and presently Technical Member of Appellate Tribunal for Electricity, New Delhi, Mr. G.N. Mathur, CBIP.(Central Board of Irrigation and Power) and Dr.E.A.S.Sarma, Former Secretary, Ministry of Power, Govt. Of India have been appointed as consultants.

Dr. EAS Sarma has shown unwillingness to work as regular consultant. However he agreed to advise on this issue. Dr. Sarma has formerly worked as Secretary, Ministry of Power, Govt. Of India and has wide experience. He has given preliminary observations on Kalpasar Tidal Power Generation on 05.01.2007. The following points of the report of Dr EAS Sarma were discussed in EAG. 1. The study seems to suggest that the emerging size of the Western

Region Power System would be sufficient to readily absorb 14,000Gwh of energy and 5,600MW of cyclic generation from the proposed tidal power facility from 2020 onwards. The cost calculations seem to suggest that at 1999 prices, the unit cost of energy would be Rs.2.42/kwh for the single-basin scheme and Rs.3.69/kwh for the double-basin scheme. These calculations need to be reviewed for the reasons explained below.

At present, the Western Region has seasonal peak demand of 51,770MW and a seasonal off-peak demand of 33,651MW. It shows the large amplitude of variation in the demand. This situation may persist even beyond 2020, when the tidal plant is expected to come on stream.

The region is thus badly in need of peak generation support in the absence of which the existing thermal plants would be forced to back down. Strictly, tidal generation cannot provide that support, as its operation depends on the ebb-tide cycles. Its cycles of generation may not necessarily coincide with the peak-off-peak

20

variations in the demand. Similarly, unless it is stored in pumped storage schemes, not all the energy from such cyclic operation can be consumed in the region.

In other words, the proposed tidal project should be so adapted in its design that it could readily fit into the Western Regional power system at optimum cost to the consumer. In a regime of merit-order dispatch, tidal power at higher generation levels may not find takers throughout the day or throughout the year. It is true that the price of coal delivered in Gujarat is high but one has to evaluate the tidal power as a part of the entire Western Region. It would be necessary therefore to formulate a dynamic mathematical programming model of the Western Regional power system (with its partial integration with the Eastern and other regional power systems) and test tidal power at different levels to arrive at an optimal configuration. Based on such simulation studies, the design parameters of tidal power will have to be reviewed.

The modeling study as above could be tried out even with the presently available technical data. Later, as and when more precise technical evaluation is available, the design parameters could be fine-tuned.

Depending on such a modeling study, the project design is likely to undergo some change. It is possible that the maximum power generation capacity of the project would get limited to a level less than even 5,600MW and annual energy generation limited to a level below 14,000GWH. In that case, the unit cost could be higher than estimated.

EAG considered the report given by Dr E A S Sarma and EAG advised that the points raised by Dr Sarma and other issues identified by the EAG in last meeting are required to be analyzed by Mr. Bajaj and Mr. Mathur, consultants.

Agenda Item No.15: To take the services of NGO’s of Gujarat in

baseline data collection for EIA/SIA study.

Dr. K.K. Ghosh & Dr. Deepa Gavli from Gujarat Ecology Society, Vadodara, Dr. Vinod Agrawal & Dr. M.D. Irfankhan from TALEEM, Ahmedabad and Dr. Gopi from CEE, Ahmedabad made a presentation on the subject of Base line Data Collection for EIA/SIA study for baseline Environment and marine issues. VIKSAT, Ahmedabad, could not make their presentation due to their engagement in other important issues. EAG, after discussion, advised that the NEERI’s scoping proposal should be given the highest priority. Chairman, EAG

21

suggested that Kalpasar Department should call a joint meeting with NEERI and all these NGOs and thereafter NEERI will suggest as to how to utilize all these NGOs. Agenda Item No.16: Strengthening of Kalpasar Project.

The issue of additional staff required from Water Resource Department and the correspondence made by the Chairman EAG and thereafter the latest progress for additional staff position was discussed in EAG meeting. EAG has opined that the Kalpasar Department has proposed the bare minimum staff for urgent activities such as field data collection, data preservation, testing works, design work, plan estimation works etc. Therefore, the EAG advised that Secretary (Kalpasar) should again pursue with the Government for obtaining the approval to the proposal for diverting the staff of Water Resources Investigations Circle, Minor Irrigation Project (CDO), GERI, WALMI and some units of Central Design Organization and Geologist from GWRDC to Kalpasar Department. Agenda Item No.17: Requirement of Additional National

Experts. The EAG has reviewed the consultants so far appointed. The EAG has again advised that the issue of appointing international consultants should be sorted out immediately with Government so that services of international experts in areas where national experts are not having sufficient experience and knowledge can be utilized. The EAG has reviewed all the studies and they have earmarked the studies in which national experts and international experts are required. The EAG also identified the priority of all studies. The details of recommendations of EAG are as under. (a) International Experts

1. Considering the availability and the area of expertise of Dr. S. Z. Qasim and looking to the reluctance of NIOT to carry out the work of 2 Km corridor and shallow depth bathymetry work, which still remains to be carried out, the EAG felt that some other national experts are required to be considered. Therefore the services of Mr.Desai, Retd. Director, NIO, stationed at Vadodara can be utilized for bathymetric surveys, oceanography and geophysical studies. Similarly, the services of Dr. J.S.Mani, who had earlier work in CWPRS, Pune, can be utilized for ocean engineering, regime modeling and morphology etc.

23

2. The EAG has also recommended to utilize services of

following in consultation with Chairman EAG:

(i) Dr. K.N.Mathur, Director General (Retd), GSI, (ii) Shri B Sharma, Retd. Director, GSI, Expert in

Marine Geology (iii) Shri V.K.Kasliwal, Retd. Director, GSI, Expert in

Engineering Geology and has also worked in the project while in service
