ownership to the Contractor, in addition to instilling in him/ her a thorough
understanding of the pertinent issues.
The responsibility for supervision of the implementation of all the proposed
mitigation measures during construction and the defects liability period will lie
with the Supervising Engineer, while the Contractor will be responsible for day to
day operational matters of construction, which will include implementation of
mitigation measures that he is responsible for. After the defects liability period,
responsibility for the operation and maintenance of the scheme will rest with the
Factory Managers. The table also presents an estimate of the costs of
environmental management and mitigation.

Solid Waste - To begin with, all
measures should be
employed to
minimize the
amount of waste
generated-this can
be done by
practicing 3Rs-
Reduce, Reuse,
Recycle, whichever
applicable.
- A waste
management plan
would be prepared
and followed
- Organic waste to be
composted for
reuse while
inorganic waste
should be properly
disposed.
- Proper waste

- Use other water

- Use of bio-digesters
- Use of stabilization

- Use of waste

such a Bio-box or

- Connection to the

depends on
availability of

- Use of conservancy
