Heating oil system Unfortunately this specification of service has not yet been completely translated.

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

Required documents are: Description of the system (above ground (e.B. in the basement) or underground tank, single-walled/double-walled, storage quantity, etc.), Proof of usability for heating oil storage under building law (service description for CE-marked plant components, designation of the DIN standard or the general building authority approvals), Proof of retention volume (size of the collection chamber), unless double-walled, information on the contracted specialist company, for commercial plants, further documents / requirements may be necessary (e.B filling station).
