The Indian Oil Corporation Limited (IOCL) proposes to augment the existing Viramgam-Koyali section of Salaya-Mathura crude oil pipeline (SMPL) by laying a 17 km length of loop line, to meet the additional crude oil requirements of Koyali refinery.

The proposed augmentation of VK section required a comprehensive and systematic study leading to planning of measures for safeguarding the natural environment of the project affected sites. Identifying major environmental impacts of the proposed pipeline and suggestions modifications in the project design, if required, also are covered by the scope of the study. The Wildlife Institute of India (WII), Dehra Dun, was offered a consultancy by the Engineers India Limited (EIL), New Delhi, to assess the environmental impacts of the project on wildlife values. The memorandum of understanding jointly signed by EIL and WII defined the scope of work for the EIA study under this consultancy.

That this EIA study commanded major significance was obvious from the fact that several important wildlife habitats such as grasslands, wetlands (rivers, lakes and ponds), and forest areas were located en route the proposed pipeline. Some of these are unique habitats for important wildlife species. This report is an attempt to identify the impacts of pipeline expansion on wildlife values of the wetlands, forests and suggest mitigatory measures for the conservation and management of wildlife species and their habitats.

This report is organised into five chapters. Chapter 1.0 of the report is an introduction to the project setting and its environment and lays the ground work for the overall approach of the EIA study. Chapter 2.0 provides impact assessment methodologies for wildlife species and their habitats used in the present study. Chapter 3.0 presents the pre-project status of wildlife values of the areas en route the proposed project. Chapter 4.0 outlines the areas of environmental concerns. Chapter 5.0 highlights some of the significant impacts of the project and offers mitigatory measures to allow proposed developmental project to progress in a manner that also safeguards the conservation of flora, fauna and their habitats.

The preparation of this report would have not been possible without the help, support and encouragement provided by various organisations and individuals.
