Over the last 15 years it has become apparent that a large proportion of facilities with odour issues have two common deficiencies: non-existent or ineffective odour management and monitoring plans (OMMP) and non-existent or rudimentary odour control systems. The uncertainty related to the operational aspects of the facility processes coupled with the inherent difficulty of assessing odour emissions for complex odour sources was the major reason of the lack of effective and appropriate odour regulatory conditions. By clearly identifying the sources and practices within an operation that have potential to emit odour, and by designing a comprehensive and relevant OMMP for moderate to high odour risk sites, industries can more effectively demonstrate to the regulator their understanding of their process and operations, pre-empt the odour risks and proactively implement corrective actions should the risk become real. This strategy is intimately coupled with appropriate monitoring of key performance indicators that are more readily accessible and accurate than odour measurements. Key elements of OMMPs can then be incorporated into regulatory conditions for premises in order to establish what may be termed “regulating by management”.
