Vorschlaege fuer Verbesserungen beim anlagenbezogenen Gewaesserschutz Auswertung einer Umfrage

The present regulations on ground water protection, particularly the 'Anlagenverordnung VAwS' (State-Regulation of the 16 German Federal States) were analyzed. Special attention was paid to regulations, such as Regulation on Flammable Liquids (VbF),... on Pressure Vessels (DruckbehV) which may lead to multiple control of a single plant. The research was performed in four phases: 1. mailing of 385 questionnaires, 2. interviews with 40 managers of plants and authorities, 3. expertise of the 'Institute for Water-Polluting Substances' and 4. evaluation of the forementioned results. The results aim both at specific adjustments of existing details within the framework of the VAwS as well as at fundamental improvements. The definition of 'plant' in the framework of the water protection is of central interest together with its licencing procedure; in this context new guidelines were proposed. The concept of 'water polluting indicator figures' (Wassergefaehrdungsklassen) for the technical layout of plants (size and quality of secondary containment) were analyzed in depth. The proposals are presented together with numerous examples under the background of the 16-fold different State ('Laender') Regulations. The implications are contrasted with Federal ('Bundes') Regulations presently under consideration (Plant Safety Code). For three central issues: improvement of the licensing procedure, development of a clear and disjunct structure of competing technical regulations, development of rules for the interace between plant and sewage the importance of novel approach is clearly demonstrated.
