The Site is seeking approval to increase its capacity to receive, store and distribute diesel and biodiesel for customers throughout the Hunter Region (the Project). The Project consists of elements which have been approved and constructed as part of previous project applications under Part 3A (repealed) of the Environmental Planning and Assessment Act 1979 (The EP&A Act), as well as new elements. The existing Facility provides terminal facilities for the storage and distribution of 500ML per annum (pa) of bulk liquid fuels, including diesel and biofuels. The Project includes consideration and assessment of the existing Facility and approved modifications as described in Section 2.6. In addition to those elements previously assessed and approved, the Project also proposes to: - Increase throughput of diesel and biofuels up to 1,010ML per annum; - Increased management of fuels within the Facility (increased pumping); - Increased distribution of fuels by road (increased vehicle movements); and - Construct and operate an additional 2 x 18ML diesel storage tanks and associated pumps, piping and safety systems. Full details regarding all elements of the Project including the relationship between approved and proposed elements is provided in Section 6.0 of the EIS. The main potential sources of air emissions associated with the proposed development are vapour emissions from the storage and transfer of fuels (volatile organic compounds, or VOCs). The purpose of this assessment was to assess the air emissions and potential impacts associated with the Project. This report provides details of the methodology and results of the dispersion modelling of VOC emissions. 1.2 Scope of Work The assessment was undertaken in accordance with the NSW Environment Protection Authority (NSW EPA) Approved Methods for the Modelling and Assessment of Air Pollutants in NSW (The Approved Methods) (DEC 2005). The assessment considered the following pertinent information: - An increase in storage tank emissions from working and standing losses due to an increase in throughput from the currently approved 500 MLpa to the proposed 1,010 MLpa; - Operation of an additional 2 x 18ML diesel storage tanks; and - The truck filling station gantry bays operating at their maximum capacity, with a gantry vapour collection stack 21 m in height with a diameter of 0.18 m and a volumetric flow rate assessed at the maximum gantry pump rate of 0.375 m3/s. VOC emissions associated with diesel and biodiesel storage from operation of the Facility were estimated through dispersion modelling using the CALPUFF model in accordance with the NSW EPA’s guidelines for air pollution assessments (DEC 2005). The assessment was also undertaken in accordance with the Port of Newcastle’s Mayfield Concept Plan Site Air Quality Model as detailed in Section 4.1.
