  "heading": "In order to reduce emissions from delivery, storage and handling of treatment chemicals, BAT is to use technique (a) or (b) and all of the techniques (c) to (f) given below.",
  "text": "Technique\nDescription\n(a)\nBack-venting\nAlso referred to as vapour balancing. Vapours of solvents or creosote which are displaced from the receiving tank during filling are collected and returned to the tank or truck from which the liquid is delivered.\n(b)\nCapture of displaced air\nVapours of solvents or creosote which are displaced from the receiving tank during filling are collected and led to a treatment unit, e.g. an activated carbon filter or a thermal oxidation unit.\n(c)\nTechniques to reduce evaporation losses due to heating up of stored chemicals\nWhen exposure to sunlight may lead to evaporation of solvents and creosote stored in above-ground storage tanks, tanks are covered by a roof or coated with light-coloured paint to reduce the heating up of stored solvents and creosote.\n(d)\nSecuring delivery connections\nDelivery connections to storage tanks located within the bunded/contained area are secured and shut off when not in use.\n(e)\nTechniques to prevent overflows during pumping\nThis includes ensuring that:\nthe pumping operation is supervised;\nfor larger quantities, bulk storage tanks are fitted with acoustic and/or optical high-level alarms, with shut-off systems if necessary.\n(f)\nClosed storage containers\nUse of closed storage containers for treatment chemicals.",
