Auditing refers to the examination and assessment of a certain type of performance. In the case of an EIA, an audit assess the actual environmental impact, the accuracy of prediction, the effectiveness of environmental impact mitigation and enhancement measures, and the functioning of monitoring mechanisms. The audit should be undertaken upon a project run in operation, for some time, and is usually performed once or twice in the entire project cycle.
The following types of audit that are recommended to be implemented in different phases of the EIA process:
Types of Audit
Not all the audit types mentioned above are required to be implemented in EIA process. However, at the project approval stage, both project proponent and authorizing agency should considered whether an application of a particular audit technique is likely to result in new information or an improvement in management practices. Particular attention should be given to the project cost-effectiveness of any proposed audit and to technical difficulties likely to be encountered.
Since the EIA concept is a relatively recent, the use of environmental audits will play a significant role in evolving a systematic approach of the application of EIA.
Environmental auditing should compare monitoring results with information generated during the pre-project period. Comparisons can be made with similar projects or against standard norms. Relating actual impacts with predicted impacts, help in evaluating the accuracy and adequacy of EIA predictions.
Environmental Auditing Plan
Environmental Audit should be carried out upon the completion of project construction and after 2 years of project operation in order to obtain information on:
Information from monitoring output should also be utilized for carrying out environmental audit:
