If you decide to build and operate a heating oil plant or shut down an existing plant, a notification will be required with the Lower Water Authority of your county or county-free city. You can see: the construction and operation of underground installations, the construction and operation of above-ground facilities within water and healing spring protection areas ("upper ground" is also a storage in the basement of a building.) the construction and operation of above-ground installations with a content of 1,000 litres of heating oil outside water and healing water and healing areas, all significant changes to the system and operation (e.g. installation of an inner shell) Decommissioning of the plant If your plant has more than 10,000 litres of content, a building permit is required. In the vicinity of cultural or natural monuments, this applies as early as 5,000 l of heating oil. In the case of larger commercial installations, an immission permit may instead be required. There is no obligation to notify in these cases.
