What if I need to keep my floor drain open for snow melt and/or vehicle wash water?
In some cases floor drains can remain open. For example, if they are connected to a holding tank (a holding tank must not have an overflow or other holes or pipes that could discharge underground) or a municipal sanitary sewer system. Another example where a floor drain can remain open is if the area where the drain is located is physically separated from the area where any vehicle service occurs. This can only be allowed if EPA can be assured that no motor vehicle service will occur in the area with a floor drain area and that only fluids from snow melt or vehicle exterior washing can enter the drain because Best Management Practices are followed. These practices would include: 1) training for employees that no wastes will be poured down the drain and no parts cleaning or motor vehicle fluids are stored in the area; 2) a sign is posted in the area to remind employees to not pour wastes into the drain; and 3) signed certification is provided that no vehicle service work will be done in
