– Mechanism to monitor compliance with the mitigation measures

– Mechanism to monitor un-anticipated impacts

– Communicate and document environmental performance and issues

– Train project personnel

– Manage changes to the project

Environmental management plan

• Roles and responsibilities–Client (PMU)–Consultant –Contractors

Environmental management plan

• Roles and responsibilities– Client

• Director • Safeguard Specialist • LAR Specialist

– Contractors• Environment and Social Officer

Environmental management plan

• Mitigation management plan– Potential impacts– Mitigation measures– Responsibility– Timing

Environmental management plan

• Monitoring plan– Compliance monitoring to check compliance with the EMP– Effects monitoring to identify unanticipated impacts of the project

• Wildlife• Fisheries• Social• Groundwater

Environmental management plan

• Training plan– Environmental trainings will be given to PMU and contractors

– Further trainings will be given under other project components staff

The Project

• Construction of RCC structure sump chamber . • Construction of pump house.• Pipe Line

the Project

1. Construction of Sub-station- Pump House 2. Laying of 3 nos 36 inch diameter M.S pipes 400 ft

length below the ground surface of Bukkur Island and 600 ft length below river bed at a depth of 5 ft.

3. Laying of 200 ft pipe in Indus Water 20 feet deep 4. 4.7 M US $ is total cost 5. Alternative cost of Project alternative is Storage

Lagoon 6. 20 M US $ with large Land acquisition and O&M cost

Route of the Project

• Description of Route • 1200 Ft length of Pipe • 00-200 ft: At the start 3x36 inches diameter

pipes will be jacked horizontally from Rohri side bank of Bukkur island below the river bed to emerge at designated depths. The water will be collected in sump at Bukkur island pipes end.

Pipe Line Route

• 200-600 ft: The proposed route starts from sump chamber on Bukkur Island and travels along the existing RoW

• 600-1200 ft: The proposed route passes through the River bed of the Indus River to reach the right bank of the Indus River at Existing Intake . ( it becomes dry when gates of Sukkur Barrage are Open )

Issues with Existing Water Intake

• subject to river flooding.• Polluted Water untreated waste water• Indus River bed dries up completely at the

location of existing intake pipes.• Below intake level – no water for city • Potential of change of river course – no more

water from existing intake .

Environmental Sensitivity

• EARF, Rapid Environmental Assessment (REA) • the proposed project is categorized as A

project • Environmental Impact Assessment report is

required .• Ramsar Site since 1974 • Indus Dolphin Reserve managed by Sindh

Wild Life Department

Protected Area for Indus Dolphin Reserve (IDR)

• Declared Protected Area, namely the Indus Dolphin Reserve (IDR) and is also a Ramsar site.

• The Indus Dolphin Reserve is one of the prime habitats of Blind Indus Dolphin (Platanista minor) with maximum population left between Guddu and Sukkur Barrages.

• Indus Dolphin Reserve boundaries cover an approximate area of 44,200 ha and are about 210km stretch between Guddu and Sukkur Barrage.

IUCN Red List Analysis : Indus Dolphin Status

• Vulnerable : species that are seen to be facing a high risk of extinction in the wild, but not necessary experiencing recent reduction in population size

No Project Option : Right Bank Water Situation during

Closure :poor water supply and water riots

Project Details: Based on Environmental Assessment

• NSUSC plans the total construction period 6 months which includes construction of sump chamber, pump house, electric panel room and laying of underground pipelines

• Pipe Line Portion in January • June –July for Pump House and Intake Pipe at

maximum width and flow ( average is 100,000) hundred thousand ) :after Mating Period

KEY ENVIRONMENT RECEPTORS

Biological & Physical Environment

• Bhakar Island include Alhagi maurorum, Desmostachya bipinata, Saccharum spontaneum, Saccharum bengalensis, Salvadora oleoides, Salvadora persica, Tamarix indica, Tamarix aphylla and etc.

• Submerge species are Typha domingensis, Typha elephantine and Phragmites karka.

• Ground water is sline

Birds:Winter Visitors

• black redstart, lesser whitethroat, Common Chiffchaff, Common Sandpiper and yellow wagtail.

• No work in the pond area of Barrage during winter

Social Environment

• No Communities living in the Island

Indus Dolphin Survey

• April 2011 SWM &WWF the population of Indus Dolphin in IDR has been estimated 1171.

• 918 Dolphins including young animals were recorded within limits of the Guddu to Sukkur Barrage.

• Sindh Wildlife Department the total population of Indus Dolphin within the project area ( Sukkur Barrage Pond Area ) is around 40-50.

• Baseline Field recorded only 6 Indus Dolphin in Winter and 24 in Summer

Baseline Survey in Summer

Key Environmental Impacts : Construction

• Disturbance due to noise – 60 dB threshold • Pain is 129 dB• 220 dB Mammals hearing system ( McCauley

1994) • Interference in swimming activity in high

depth water • Disturbances to breeding period

Environmental Mitigations

( Construction ) : Dolphin

• Pipe Laying (25th December to 10th January). No Dolphin at Right Bank

• Gradual Start of activities at Jacking Point • Continuous monitoring and escorting the area in Summer

season during jacking .• Gravity Intake water flow• No Vibrations as Pump house on Piles • Noise less then 60 dbs • No Jack Hammering – Piston Movement – one week

duration Maximum with 2 H interval for 8 hours daily • 100 Meter is based on potential impact corridor – expert

judgment

Environmental Mitigations

Construction : Dolphin

• The jacked pipe water intake system - mesh size (5mm) to avoid Dolphin

• Ensure presence of Indigenous divers in 100 meters zone

• Stop all activities in case a dolphin sighting enters into 200 meters

• Jacking above 30,000 cusecs and preferably above 50,000 cusecs

• No activity below 30,000 cusecs flow

Environmental Mitigations: Dolphin

• Ensure Divers and Train Rescue Team of SWD &WWF is present all the time in the impact area of Jacking ( during Construction) to avoid any potential catch or disturbance to Indus Dolphin around Jacked Piped area of 100 – 200 meter circle zone

Environmental Impacts -Operations : Dolphin

• Noise and Vibration • 36 inch pipe inlet

Environmental Mitigations Operations : Dolphin

• Low Noise pumps away 100 ft from Bank on piles

• 36 inch pipe inlet – Mesh Cover • Monitoring • Low operations of Generators in Breeding

Period – conjunctive use of Old Intake Pumps

EMP Compliance & Monitoring

• NSUSC – Safeguard Cell • Independent Environmental Monitoring

Consultants – One year • Site Specific EMP • No Objection Certificate (NOC) issued by the

Sindh Environmental Protection Agency (SEPA) • Compliance of ADB Safeguard Policy 2009 and

Environmental Assessment Guidelines 2003•

Env Monitoring with focus on Dolphin-Parameters

• Disturbance to Indus Dolphin Density/population or species diversity

• Affects Monitoring – Sindh Wild Life Department

• Compliance Monitoring – by IMC • Cost provided • Partnership with SWD for Dolphin Monitoring

Conclusion

• All the impacts after mitigation of impacts are insignificant, reversible and of short term duration.

• Visible positive impact on the socio-economic conditions of the local residents of the area.

• Dolphins will be significantly away from the Intake area activity in medium to high floods as observed in summer survey and potential impacts or threat is minimum
