Environment and Approvals Visual Presentation EA01 Compliance with local and state environmental noise criteria is a critical requirement for the successful delivery of oil and gas projects. However, these criteria vary between jurisdictions, creating challenges for standardised design approaches. Such variability can materially affect facility design, as it determines the extent of noise control measures required to achieve regulatory compliance. The required noise control measures can also influence other design aspects, with associated cost implications and effect on project timelines. These design aspects may include, among others, visual amenity, site layout, mechanical and ventilation design. This paper reviews the range of environmental noise assessment criteria applied across Australian jurisdictions and looks at the potential implications their differences have on the design of new facilities. Noise limits are commonly derived from existing background noise levels and/or tied to the land zoning of the noise-affected area. Regulatory authorities may adopt either one or both of these approaches in defining noise limits. Authorities may also vary in their assessment approach in terms of how closely the proponent and acoustic consultant must adhere to a particular assessment methodology and what steps need to be taken should there be a predicted exceedance. By identifying and understanding these differences early on, proponents can better consider noise management requirements from the outset, as early as the site feasibility stage. A comparative case study is presented for a gas compressor facility modelled under regulatory frameworks from multiple states, highlighting variations in predicted acoustic outcomes and their potential implications for site feasibility and project costings.
