Environment Clearance
CWC Guidelines
Mandatory since 1994 as per the EIA notification (Under EPA, 1986): Need for EIA and Public Hearing for a project before clearance
Specific Amendments related to River Valley projects in the notification

Brahmaputra river system
International river: China, India, Bangladesh
Highly seismic zone, glacial origins, heavy rainfall –
flashy
Second highest sediment, fourth highest volume
Wetlands, grasslands, fisheries, agriculture
“Geological surprises”
![Page 10: Role of EIAs in Biodiversity, Wildlife and Forest Protectioniced.cag.gov.in/wp-content/uploads/Role-of-EIAs-in-Biodiversity-and... · Rehabilitation Environment Clearance Conditions-Hill](https://reader036.vdocuments.site/reader036/viewer/2022070113/605c273a981b6861e125eb15/html5/thumbnails/10.jpg)
Decision making
Balancing environment and development: Sustainable Development (socio-env vs techno-eco)
Scoping, assessment, public hearings, appraisal, approval
Complex ecosystems- challenging
Rapid, Post clearance EIAs
Subansiri, Dibang and Demwe- “compromised documents” but all granted clearance
![Page 11: Role of EIAs in Biodiversity, Wildlife and Forest Protectioniced.cag.gov.in/wp-content/uploads/Role-of-EIAs-in-Biodiversity-and... · Rehabilitation Environment Clearance Conditions-Hill](https://reader036.vdocuments.site/reader036/viewer/2022070113/605c273a981b6861e125eb15/html5/thumbnails/11.jpg)
EIA documents
Incorrect data: eg: 55 species of fish instead of 156
No data: (downstream areas/ impacts beyond project site/no risks other than dam break inspite of accidents)
No peer review; so much hidden by methods, choices of data analysis eg: averaging vs counting
Fresh data may be needed, usually sought after approval; fait accompli
Post facto assessments: Did the EIA get it right?
![Page 12: Role of EIAs in Biodiversity, Wildlife and Forest Protectioniced.cag.gov.in/wp-content/uploads/Role-of-EIAs-in-Biodiversity-and... · Rehabilitation Environment Clearance Conditions-Hill](https://reader036.vdocuments.site/reader036/viewer/2022070113/605c273a981b6861e125eb15/html5/thumbnails/12.jpg)
Social Impacts
PAP: Small displacement in actual numbers by comparison to dam projects (large by percentage due to small populations, eg Idu Mishmi- 9500)
Percentage of land for project: Unconventional land arrangements for livelihoods due to geography (altitude, weather and soil conditions)
Common use areas, lands without property titles, readily compensated
Ethnic territories, so resettlement is a problem
Influx: Dibang valley, 1,50,000 workers for 17 projects
![Page 13: Role of EIAs in Biodiversity, Wildlife and Forest Protectioniced.cag.gov.in/wp-content/uploads/Role-of-EIAs-in-Biodiversity-and... · Rehabilitation Environment Clearance Conditions-Hill](https://reader036.vdocuments.site/reader036/viewer/2022070113/605c273a981b6861e125eb15/html5/thumbnails/13.jpg)
The river matters
“Run or the river”- no permanent pondage
Fluctuating rivers: starving and flooding of rivers. (6-2500 cumecs, winter normal-400)
So regular winter floods every evening during peak demand; affect on fisheries, agriculture, livestock and transporatation
Wetland ecosystems (Kaziranga, Dibru ) Engandered spp (B. Florican)
Cumulative impact: upto 4 m (13 ft) of water in d/s areas (Dibru)

EIA policy problems
EIA consultants paid by Company
Public come in too late in the process; public comments not used in decisions
Conflict of interest: Head of EAC resigned in 2009 (DemweL +PTC)
Kalpavriksh & Others v. Union of India, Writ Petition (Civil) No. 2667 of 2011 in High Court of Delhi
Almost all projects get approval (2009-10: 90%)

No dumping in forest areas, river beds but
only in designated places
Catchment Area Treatment
Compensation for loss of forests (e.g.
afforestation, declaration of PAs)
Facilities for labour: medical and
recreational
Rehabilitation
Environment Clearance

- Hill areas dont have enough flat land for
dumping sites; project proponents find
transportation expensive
- Road construction/ dumping of debris in
forest areas
- Violations recorded by FD, MoEF regional
office, PCB
Excavation and Disposal of
Muck/Debris

Catchment Area Treatment (CAT)
Project Proponent transferred money to Forest Department, delay in undertaking CAT by FD (NHPC-Parbati II)
CAT money spent on purchase of equipment, vehicles, repair of rest houses etc.
NHPC troubled as siltation affecting dam - no construction upstream of the dam/diversion sites
