8.1.2.3 Control/Mitigation6. It is not possible or even practical to avoid all impacts. Following proper control/mitigationmeasures will reduce (i.e., control) the extent of impact on the environment. The best constructionpractices also helps in reducing the extent of impact. For example:Tree felling prior to birds’ breeding time will reduce the impact on bird’s habitatThe intensity of the noise impact on a noise sensitive area will be lessened by using lownoise/vibration generating equipment or incorporating noise dampeners.Management of products, fuels, waste and excess materials during construction will minimizewaste generation and associated impacts and will also minimize impacts associated withmaterial handling and storage.8.1.2.4 Protection/Insulation7. Protection/insulation of receptors from impacts will reduce the impacts that remain after controlmeasures have been used. The extent of these measures will be proportional to the environmentalsignificance of the feature to be affected and the ability to reasonably mitigate the impacts. ForexampleFencing around the designated areas of winter birds and habitats to avoid humanencroachmentNoise walls/barriers are an example of insulation measures used to mitigate noise impacts.8.1.2.5 Relocation/Compensation8. Compensation refers to the provision of “equivalent” environmental features. For example,Loss of aquatic and wildlife habitats are compensated with the establishment of a ProtectedArea in Charland.Tree plantation along the approach road, RTW alignment, and around the resettlement sites.8.1.2.6 Enhancement9. Enhancement refers to the provision of features that are an improvement over previousenvironmental conditions. For exampleDevelopment of green beltsPromote ecological conservationProviding training and opportunities for the affected community8.1.3 Monitoring Mechanism10. Monitoring of environmental components and mitigation measures during construction andoperation stages is a key component of the EMMP. The objectives of the monitoring are to (i) monitorchanges in the environment during various stages of the project life cycle with respect to baselineconditions; and (ii) manage environmental issues arising from construction works through closelymonitoring the environmental compliances. A monitoring mechanism is developed for each identifiedimpact and it includes: Location of the monitoring (near the Project activity, sensitive receptors or within the Projectinfluence area) Means of monitoring, i.e. parameters of monitoring and methods of monitoring (visualinspection, consultations, interviews, surveys, field measurements, or sampling and analysis) Frequency of monitoring (daily, weekly, monthly, seasonally, annually or duringimplementation of a particular activity)8-5
