actual field measurement or vendor sound emission data where possible to ensure
the accuracy of sources.
3.4.4.8 Monitoring Plans
Since noise impacts are predicted to be negligible, a monitoring program for
noise is not considered necessary. As part of the on-going community relations
program, a process for addressing noise complaints will be developed. Should a
noise complaint be received during project operations, an investigation will be
conducted to identify the source of the noise and determine possible solutions, if
necessary. The investigation may include measurement/monitoring, interviews
or modelling.

Conclusions
Noise levels from pipeline construction activity are expected to attenuate to
World Bank nighttime criteria of 45 dBA within 500 to 700 m from activity.
These noise levels could be sustained for as long as one week at any point along
the route. Due to the localized effects for noise and expected short duration of
construction, impacts are not considered significant.
