Report of the Comptroller and Auditor General of India on Conservation of Coastal Ecosystems https://cag.gov.in/uploads/download_audit_report/2022/Annexures-062f1f1d0d49e77.19962378.pdf
Name of Project: Mumbai Coastal Road Project (South) - Princess Flyover to Worli end of Sea Link by M/s Municipal Corporation of Greater Mumbai
Risk to marine flora and fauna, ecologically vulnerable areas: The EIA stipulated that the mangroves in the project area would be impacted leading disappearance of reproduction and food zone for species of fish, aquatic and migratory birds, Irreversible salinisation and acidification and Coastline erosion.
Mitigation measures not envisaged in the EIA: Against such consequences, the mitigation measures suggested are merely perfunctory such as dust suppression measures, sprinkling of water, monitoring of noise etc. and did not directly address the impacts identified.
Risk to marine flora and fauna, ecologically vulnerable areas: The EIA report identified impacts, such as: Formation of sediment plumes that would affect fish and benthos, increased turbidity affecting the growth of the plants, increase in PH of the water causing algal bloom, increase in temperature with reduced dissolved oxygen, Immediate and long term degradation of sensitive and essential breeding and nursery habitats for marine organisms leading to long term reduction in commercially important fish.
Mitigation measures not envisaged in the EIA: It was observed that the mitigation measures suggested like the use of best practicable technology, appropriate handling of liquid and solid wastes and adequate noise control measures did not directly address the identified impact.
