The applicant seeks to renew the necessary regional resource consents to enable the continued existence, operation and maintenance of the coastal marine structures, abstraction of groundwater, and discharges to land air and water from Refinery activities, including the future potential operation of the site as a terminal. 5. A summary of the proposal is set out below and Section 3.0 of the applicants AEE describes the proposal in full detail. The key activities and structures that form part of the proposal are: . Three jetty structures and associated mooring dolphins and breasting moorings; . Discharges to air; . Discharges to land; . Discharges to the coastal marine area; and . Abstraction of groundwater 6. The applicant has noted in the application that activities associated with shutdown and maintenance work outside the scope of this proposal will be determined if they can be carried out within permitted activities criteria or require a resource consent. If resource consent is required, it will be sought for on a ‘project by project’ basis, at the time in which the shut down or maintenance activity is to be scheduled / planned. The applicant has made one exception and that is for wet and dry abrasive blasting to be undertaken on land to remove existing coatings, to enable repair and/or maintenance. S113 DELAUTH RPT SEPTEMBER 2020 (REVISION 6) 2 A1418103 1.2.1 Jetties and Associated Structures 7. The three jetty structures and associated mooring dolphin and breasting moorings form a crucial part of infrastructure for the on‐going operation of the Refinery, as shown in Figure 1. As noted in the application, approximately 40% of refined product leaves the site via coastal tankers to other domestic centres. With up to 210 tankers visiting the refinery in previous years, the jetty structures enable these vessels to safely berth and either unload crude oil or load refined products. 8. Jetty 1 and 2 where constructed in 1960s and have been regularly maintained, (AUT.008319.06.01). Jetty 3 was built in 2009 to provide loading facilities for a ship bunkering vessel (AUT.008319.12.02). Figure 1: Location of the Jetties, (Sourced: Application) 9. Jetty 1, referred to as ‘the Crude Jetty’ is utilised by the tankers bringing crude oil to the Refinery, where they berth to unload. Jetty 2 ‘the Product Jetty’ is predominantly used to load tankers with refined product destined for other centres or markets. When required Jetty 2 can also be used to unload vessels. The wastewater diffuser outfall structure is also located on Jetty 2. 10. Jetty 3 includes a purpose‐built berth, for fuel barges, consented in 2008, extending approximately 128m to the west. 11. The main jetty structure, provides access to the three jetties, houses a number of structures that facilitate the operation of the loading and unloading of the vessels. The facilities consist of toilets and sewerage holding tanks, fire pump diesel tanks, slops tanks, various pipes and loading gantries. 12. The breasting moorings and mooring dolphins are required for the mooring of vessels visiting the refinery. There are eleven breasting dolphins which occupy an area of approximately 25m2 each and are attached to the jetty structures. The four mooring dolphins occupy approximately 20m2 each. S113 DELAUTH RPT SEPTEMBER 2020 (REVISION 6) 3 A1418103 13. The applicant also holds resource consent (AUT.038275.01.01‐AUT.038275.01.07) for capital and maintenance dredging of the seabed around the eastern dolphin moorings, including the associated dredging activities which expire on 31 May 2022. The applicant is not seeking to renew these consents, due to the recently granted ‘Crude Shipping Project’ resource consents AUT.037197.01.01 – AUT.037197.13.01, which encompasses the area and therefore will supersede them, expiring on 17 July 2053. 14. Therefore, this application covers the continued occupation and use of the three existing jetty structures and associated breasting and dolphin moorings, including the auxiliary structures and the wastewater diffuser outfall structure located on Jetty 2 and the stormwater basin overflow spillway structure within the coastal marine area. 1.2.2 Discharges to Air 15. As outlined in the application, there are five key types of discharges to air from the site: . Emissions of contaminants to air, from the furnaces that are used to heat the crude oil and intermediate products; . Fugitive emissions from various sources, relief valves, pump seals, compressor seals, valves, sample points and storage tanks that are located throughout the site; . Flaring of gases from the flare stacks due to upsets and emergencies; . Smoke from firefighting exercise during training; and . Sand/particle blasting activities undertaken as recurrent maintenance activities on site. 16. The applicant has a number of management strategies to minimise the effects of the discharges to air, which are outlined in the application under section 3.4.2 of the AEE and encapsulated in the proposed conditions. 1.2.3 Discharges to Land 17. The three main points of discharge to land are from the Accidentally Oil Contaminated System (AOC), Continuously Oil Contaminated System (COC) drainage networks and via leakages from the storage tanks. Historic activities are also involved in contributing to contaminates to land, that are still working their way through the soil horizon. 18. The drainage networks of the AOC are not completely lined and are therefore permeable in some parts. It is expected that stormwater percolates from some of these drains, containing dissolved hydrocarbons and metals, making their way into the underlying groundwater resources. The applicant also acknowledges that some parts of the COC are permeable and expects some discharges to ground to occur as a result. 19. The refinery has three storage areas, the Crude Storage Area, and two product storage areas. Leakage from these areas does occur, with the contaminates leaching into the groundwater table. 1.2.4 Discharges to Coastal Marine Area 20. The applicant identifies four broad types of discharges associated with its wastewater, stormwater, firefighting system, and ground water abstraction. S113 DELAUTH RPT SEPTEMBER 2020 (REVISION 6) 4 A1418103 1.2.5 Wastewater 21. Site wastewater is derived from three main sources, process water, ship de‐ballast water and ship tank washing. It is noted in the application that
