Flood Impacts and Cross
Drainage Structures
CONSTUCTION PHASE
During the construction phase water spraying is needed to aid
compaction of the material. After the compaction, water spraying
should be carried out at regular intervals to prevent dust.
Vehicles delivering materials should be covered to reduce spills and
dust blowing off the load.
Vehicles and machinery are to be maintained so that emissions
conform to National and State standards.
All vehicles and machineries should obtain Pollution Under Control
Certificates (PUC).
Construction of noise barriers of an average length of 100m and
eight feet height where ever necessary.
Proper maintenance of the rail track and rail wagon, by frequent
lubrication to avoid frictional noise.
Regular monitoring shall be carried out as per the Environmental
Monitoring Plan.
Impacted ponds can be enhanced by constructing bridged structures
like Gabions to avoid plugging of springs.
Any pond hit During Construction phase will be compensated t
and an equivalent area lost may compensate the loss of effective
pond area.
Filling of low lying areas like paddy fields shall be done
Formation level should be raised according to the design and the
cross drainage structures suitably planned for the flood events.

Contamination from
Wastes
In sections along watercourses, earth and stone will be properly
disposed of so as not to block rivers and streams, thereby
preventing any adverse impact on water quality.
All necessary measures shall be taken to prevent earthworks and
stone works from impeding cross drainage at streams and 7canals
or existing irrigation and drainage systems in c8onformity to the
Contractors visual integration and management plan and EMP.
All justifiable measures will be taken to prevent the wastewater
produced during construction from entering directly into rivers and
irrigation systems
