Permit (Application) Number: PPC_A_1163789 Applicant: Marine Harvest (Scotland) Ltd 1 NON TECHNICAL SUMMARY OF DETERMINATION PPC requires that where the draft determination of an application or a SEPA initiated variation is to be subject to public consultation (this is usually referred to as PPD consultation) the decision document will contain a non technical summary of the determination. There is no need to have a non technical summary if the application is not subject to PPD Will the draft determination be subject to public consultation? Yes The Marine Harvest (Scotland) Ltd manufacturing facility at the site of the former Allt-An-Avaig Quarry at Kyleakin, Isle of Skye is designed to receive and process wet and dry bulk raw materials to produce salmon feed in dried pellet form. The facility includes a new pier and slipway which will enable most of the raw materials and final product pellet to be transported to and from the site by sea. The site’s coastal location in the north west of Scotland will enable access and transport links by ship, offsetting a proportion of road use, to existing Marine Harvest salmon farms and to overseas customers. Proposed Installation Activities The Activities carried out at the Stationary Technical Unit are the treating and processing of animal and vegetable matter being an activity falling within paragraph d(iii) of Part A of Section 6.8 of Schedule 1 of the regulations. The manufacturing process involves the production of dried pelleted salmon feed at a plant with production capacity of up to 170,000 tonnes per year. The manufacturing process is depicted on the simple schematic diagram below, and involves two separate process lines and includes a number of clearly identifiable steps such as: receipt and transfer of raw materials to storage; dosing / weighing / mixing; fine grinding and control sifting; mixing; extrusion; drying; pre-cooling and coating; and final storage and bagging. A complete process description can be found in Section 3.0 of the Supporting Document to the application. Figure 1: Simple Process Schematic Permit (Application) Number: PPC_A_1163789 Applicant: Marine Harvest (Scotland) Ltd The facility also requires a number of Directly Associated Activities to be carried out on the same site including combustion (drying of material and production of steam) generation, effluent treatment and storage of raw materials etc. The steam boiler supplies thermal energy for the extrusion and drying processes and is rated at 7.9 MW net rated thermal input. Dryers serving both Lines 1 and 2, have a combined total of 9.75 MW net rated thermal input. The facility includes a bulk fuel storage facility which will provide liquefied natural gas (LNG) to fuel the steam boiler and dryers. The solid raw materials consist of vegetable meal, wheat and grain, and fishmeal. These deliveries are received by vessel at the pier and extracted under vacuum via enclosed conveyors to the relevant bulk silos. The liquid materials are vegetable and fish oils. These are pumped from the vessel to an appropriate liquid storage silo which are located in an impermeable bunded area. Water is used in the milling and blending process with a measured quantity of the different raw materials to produce the desired blended meal that is subsequently extruded to form the feed pellets that are then dried in a hot air stream. The spent air undergoes treatment through abatement systems, being routed through either bag filters or high efficiency cyclones before undergoing odour treatment in a biological treatment unit (‘biofilter’), with the treatment configuration dependant on the source zone of the spent air. Wastewaters from the milling and blending processes are treated at an on-site treatment plant before discharge to the sea via a long sea outfall. Surface water from roofs and hard standing is collected by a separate piped system that is conveyed to two SUDs treatment areas (east and west ponds) prior to discharge to the sea. Outdoor work areas, including the piers, where there is a risk of oil spillage are drained via suitable oil-water separators. The process is capable of operating on a 24-hour, 7 days a week basis, with maintenance and cleaning operations taking place
