slide4. Background of the project The proposal for grant of Terms of Reference (ToR) to the project 'Deepening and Widening of Approach Channel to Second Chemical Berth SCB at Pir Pau, Mumbai Port water area, Mahul, Mumbai, Maharashtra promoted by M/s Mumbai Port Trust was considered by the Expert Appraisal Committee (Infra-2) in its 26th meeting held on 14-15 December, 2017. on 22.03.2018 and the ToR letter recieved on 22.03.2018
The required Public Hearing has been carried out as per the Terms of Reference (ToR) through MPCB and Hon Collector office after grant of CRZ recommendations from MCZMA
MCZMA recommended the projet to MoEF & CC in its 131st meeting held on 06.03.2019<br>
slide5. COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE Point 1: Importance and benefits of the project.
Reply:
Increased depth and width of the channel will cater the need of larger new generation vessels to board at MbPT.
Time will be saved due to better movement by vessels.
Fright cost will be reduced due to larger vessels.
The development is envisaged to play a significant role in strengthening connectivity along the Maharashtra coastline.
Enhancement in economy of Maharashtra.
Substantial positive impact on socio-economic profile of the area, in Particular, and Raigad, in general, both in terms of overall employment and skill development of local workforce
Direct as well as indirect employment potential is envisaged<br>
slide6. COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE Point 2: The EIA should specifically address to the environmental impacts of drilling and blasting and give an analysis of alternatives along with mitigation plans
Reply:
Environmental impacts of drilling are as follows-
The deepening by additional 1m at berth pocket will have to be carried out either by cutter suction dredger or under controlled blasting to avoid damage to existing pile structures.
Dredging work in water cause resuspension of sediments and turbid water.
Dredging will cause high turbidity, removal of nutrient due to dredging, which would ultimately affect the marine flora and fauna.
Dredging disturb bottom sediments and induce resuspension, dispersal and settlement of such sediments. Dumping of dredged material directly alters bottom configuration and biota and may disperse toxic or harmful chemicals around the disposal site.
Due to the rock dredging and development port at an offshore location, marine life will be impacted. Cont..<br>
slide7. COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE MITIGATION MEASURE
Ground vibrations can be controlled by determining the right size of charges in relation to the drilling patterns and the firing sequence. Just like mitigating ground vibrations, the most effective way to reduce both the pressure and impulse of a shock wave is to reduce the charges through reduction of spacing between blast holes and charging fewer explosives in the rock.
Another method to mitigate the pressure of underwater shock waves is to use an air bubble curtain around the blasting zone. The air bubble curtain is produced by using perforated steel pipes, through which air is pumped and bubbles up to the surface. The shock waves in the water are partly absorbed in the bubbles – the air bubble curtain reduces the peak pressure of the shock but not the impulse of the wave.
The air bubble curtain is one method but other methods such as acoustic deterrent devices can also be utilised. The acoustic deterrent devices can emit specialised acoustic signals to safely and temporarily deter various marine fauna species from marine construction sites.<br>
slide8. COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE Point 3: A report on the impacts of dredging disposal on the DS-3 site along with the total holding capacity, the material already dumped and the spare capacities available for utilisation
Reply:
CWPRS have detailed dispertion studies on the Mathematical Model of Mumbai Harbour. They have concluded that the DS3 location which is on the 20m contour is most suitable and the dumping of material will have no adverse affect.
CWPRS also stated that the capacity of said location is 100 million cu. M. it is proposed to deposed of the dredged material at the dumping station DS3 identified and studied and recommended by the CWPRS, Pune the dumping station DS 3 is proposed to be utilized for the project of Mumbai Port Trust

Reply: Layout of SCB channel is as under COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE<br>
slide19. Point 14: A detailed impact analysis of rock dredging
Reply: Possible impacts due to rock dredging are as follows
Ground vibration, which is the energy from the blast transmitted through the rock or ground, can occur from the blasting.
These vibrations are determined by various factors such as quantity of charges, characteristics of the rock and distance from the blast.
There is a risk of propagation between (blast) holes in underwater blasting. This could cause larger total charges to be detonated at the same time as well as stronger ground vibrations.
The energy from the blast can be transmitted in various directions in the water and at different frequencies – these frequencies are high at short distances but are reduced further from the blast.
Underwater shock waves are another impact from blasting that can cause damage to nearby structures, aquatic fauna and even vessels and people in the water. In water, the explosive energy is transmitted with great efficiency, which means that the shock wave has high destructive power even over large distances.
Moreover, the pressure of the shock waves is higher if the explosive is detonated freely in the water – the maximum pressure is 10 times higher if the explosive is detonated on a rock surface instead of a blast hole drilled into the rock COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE<br>

As per the discussion had with the Dy Conservator, for handling bigger ships at SCB the Turning Circle shall be made in front of Berth for ease of navigations and the existing Channel is also need to be deepened and widened
CHANNEL ALIGNMENT
Since this is a brownfield expansion, with approach channel already in place and deepened to 9.0 m, it is considered prudent to maintain the present alignment and modify only widths and depths of the channel
CHANNEL DEPTH
For determining the depth required in the approach channel to SCB, the use of optimal tidal window and the depth available just prior to entering approach channel to SCB i.e. JD channel needs to be considered for providing the most economical/feasible solution. The components to be evaluated for determination of the channel depth are as follows:
Static draft of the design ship
Under keel clearance required for various environmental parameters
Allowance for siltation
Optimisation based on the depth of approach channel to JD1, 2 &3<br>
slide58. DESIGN WIDTH ESTIMATION OF APPROACH CHANNEL WIDTH OF APPROACH CHANNEL FOR VARIOUS DESIGN VESSEL<br>
slide59. CHANNEL DESIGN & DREDGING VOLUME Dimensions of the proposed deepening and widening is as under:
Width of the Channel = 300 m
Depth of the Channel = 10.5 m below CD
Radius of Turning Circle = 460 m
Depth at Berth pocket = 14.0m below CD
The size of the berth pocket does not require modification. Dredging Volume:
Channel Depth 10.5 m and Berth Pocket Depth 14 m (Below CD)
Total quantum of dredging = 6.6 lakh Cu. m
Total quantum of rock dredging = 1.0 lakh Cu. m
Total quantum of soil dredging = 6.6 – 1.0 = 5.6 lakh cu. m<br>
slide60. DREDGING PROCESS The dredging process consists of following three elements:
Dredging: the process of removal of sediments and/or from the bed of the water body.
Transport of excavated material: transporting materials from the dredging area to the DS 3 site which is suggested by CWPRS.
Selection of Dredging Equipment
The most suitable types of dredgers to complete the dredging work of this nature in shortest possible time is Trailing Suction Hopper Dredger (TSHD) and Cutter Section Dredger (CSD). From the available bore hole data at berth pocket it can be seen that nature of strata is weathered rock which can be dredged with powerful cutter suction dredger. If the rock is sound/hard, it may not be economical to dredge with CSD.<br>

Direct as well as indirect employment potential is envisaged<br>
slide6. COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE Point 2: The EIA should specifically address to the environmental impacts of drilling and blasting and give an analysis of alternatives along with mitigation plans
Reply:
Environmental impacts of drilling are as follows-
The deepening by additional 1m at berth pocket will have to be carried out either by cutter suction dredger or under controlled blasting to avoid damage to existing pile structures.
Dredging work in water cause resuspension of sediments and turbid water.
Dredging will cause high turbidity, removal of nutrient due to dredging, which would ultimately affect the marine flora and fauna.
Dredging disturb bottom sediments and induce resuspension, dispersal and settlement of such sediments. Dumping of dredged material directly alters bottom configuration and biota and may disperse toxic or harmful chemicals around the disposal site.
Due to the rock dredging and development port at an offshore location, marine life will be impacted. Cont..<br>
slide7. COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE MITIGATION MEASURE
Ground vibrations can be controlled by determining the right size of charges in relation to the drilling patterns and the firing sequence. Just like mitigating ground vibrations, the most effective way to reduce both the pressure and impulse of a shock wave is to reduce the charges through reduction of spacing between blast holes and charging fewer explosives in the rock.
Another method to mitigate the pressure of underwater shock waves is to use an air bubble curtain around the blasting zone. The air bubble curtain is produced by using perforated steel pipes, through which air is pumped and bubbles up to the surface. The shock waves in the water are partly absorbed in the bubbles – the air bubble curtain reduces the peak pressure of the shock but not the impulse of the wave.
The air bubble curtain is one method but other methods such as acoustic deterrent devices can also be utilised. The acoustic deterrent devices can emit specialised acoustic signals to safely and temporarily deter various marine fauna species from marine construction sites.<br>

slide19. Point 14: A detailed impact analysis of rock dredging
Reply: Possible impacts due to rock dredging are as follows
Ground vibration, which is the energy from the blast transmitted through the rock or ground, can occur from the blasting.
These vibrations are determined by various factors such as quantity of charges, characteristics of the rock and distance from the blast.
There is a risk of propagation between (blast) holes in underwater blasting. This could cause larger total charges to be detonated at the same time as well as stronger ground vibrations.
The energy from the blast can be transmitted in various directions in the water and at different frequencies – these frequencies are high at short distances but are reduced further from the blast.
Underwater shock waves are another impact from blasting that can cause damage to nearby structures, aquatic fauna and even vessels and people in the water. In water, the explosive energy is transmitted with great efficiency, which means that the shock wave has high destructive power even over large distances.
Moreover, the pressure of the shock waves is higher if the explosive is detonated freely in the water – the maximum pressure is 10 times higher if the explosive is detonated on a rock surface instead of a blast hole drilled into the rock COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE<br>

slide47. DISASTER MANAGEMENT PLAN AGAINST CYCLONE The A cyclone is a storm accompanied by high speed whistling and howling winds. It brings torrential rains. A cyclonic storm develops over tropical oceans like the Indian Ocean and Bay of Bengal and the Arabian Sea. Its strong winds blow at great speed, which can be more than 118 km/hr. When a cyclonic storm approaches, the skies begin to darken accompanied by lightning and thunder and a continuous downpour of rain Safety activity to be performed before and during cyclone
Create storm awareness by discussing effects of a cyclonic storm with members so that everyone knows what one can and should do in an emergency. This helps to remove fear and anxiety and prepares everyone to respond to emergencies quickly.
Keep your valuables and documents in containers, which cannot be damaged by water.
Keep lanterns, torches and spare batteries ready. These must be kept in secure places and handy.
Make plans for people who are either sick, suffer from disabilities, aged and children.
Keep trees and shrubs trimmed. Remove damaged and decayed parts of trees to make them resist wind and reduce the potential for damage. Cut weak branches and make winds blow through.
Continue to listen to warning bulletins and keep in touch with local officials. Keep radio sets in
working condition. Battery powered radio sets are desirable.
Evacuate people to places of safety when advised COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE<br>
slide48. DISASTER MANAGEMENT PLAN AGAINST CYCLONE Activities which should not be done during cyclone
During the storm do not venture out unless advised to evacuate.
If you have a vehicle and wish to move out, leave early before the onset of a cyclone.
Avoid remaining on the top floor of dwellings. Stay close to the ground.
Avoid taking shelters near damaged buildings or near trees.
Do not touch power lines. One may get electrocuted. Activities which are recommended to do after storm/Cyclone
Watch out for broken glass and other sharp items in debris.
Watch out for snakes and insects. Try to call for help.
Listen to the advice of local officials and emergency workers.
Be sure that the storm has subsided before venturing out. It is advisable to wait for the "all clear message" on radio and TV networks.
Wait for emergency relief teams to arrive. It may take a little time before relief becomes effective.
Stay away from flooded areas COMPLIANCE TO ADDITIONAL TERMS OF RREFERENCE<br>

Channel widths : 370 m along straight stretches and 450 m at bends.
The existing design depth of main channel at outer section :15.9 m below CD
Design depth of main channel near JD4 : 14.7 m below CD. Depths available at various sections for approaching FCB/SCB<br>
slide56. THE DEPTHS AVAILABLE AT VARIOUS SECTIONS FOR APPROACHING FCB/SCB DESIGN VESSEL CHARACTERISTICS<br>
slide57. DESIGN OF APPROACH CHANNEL The approach Channel used by the ships for the first chemical berth would also be used by the Second Chemical berth as envisaged earlier. Presently the approach Channel is maintained at (-) 9.0 M CD. As per the discussion had with the Dy Conservator, for handling bigger ships at SCB the Turning Circle shall be made in front of Berth for ease of navigations and the existing Channel is also need to be deepened and widened
CHANNEL ALIGNMENT
Since this is a brownfield expansion, with approach channel already in place and deepened to 9.0 m, it is considered prudent to maintain the present alignment and modify only widths and depths of the channel
CHANNEL DEPTH
For determining the depth required in the approach channel to SCB, the use of optimal tidal window and the depth available just prior to entering approach channel to SCB i.e. JD channel needs to be considered for providing the most economical/feasible solution. The components to be evaluated for determination of the channel depth are as follows:
Static draft of the design ship
Under keel clearance required for various environmental parameters
Allowance for siltation
Optimisation based on the depth of approach channel to JD1, 2 &3<br>
slide58. DESIGN WIDTH ESTIMATION OF APPROACH CHANNEL WIDTH OF APPROACH CHANNEL FOR VARIOUS DESIGN VESSEL<br>
slide59. CHANNEL DESIGN & DREDGING VOLUME Dimensions of the proposed deepening and widening is as under:
Width of the Channel = 300 m
Depth of the Channel = 10.5 m below CD
Radius of Turning Circle = 460 m
Depth at Berth pocket = 14.0m below CD
The size of the berth pocket does not require modification. Dredging Volume:
Channel Depth 10.5 m and Berth Pocket Depth 14 m (Below CD)
Total quantum of dredging = 6.6 lakh Cu. m
Total quantum of rock dredging = 1.0 lakh Cu. m
Total quantum of soil dredging = 6.6 – 1.0 = 5.6 lakh cu. m<br>
slide60. DREDGING PROCESS The dredging process consists of following three elements:
Dredging: the process of removal of sediments and/or from the bed of the water body.
Transport of excavated material: transporting materials from the dredging area to the DS 3 site which is suggested by CWPRS.
Selection of Dredging Equipment
The most suitable types of dredgers to complete the dredging work of this nature in shortest possible time is Trailing Suction Hopper Dredger (TSHD) and Cutter Section Dredger (CSD). From the available bore hole data at berth pocket it can be seen that nature of strata is weathered rock which can be dredged with powerful cutter suction dredger. If the rock is sound/hard, it may not be economical to dredge with CSD.<br>
