All new gasoline filling stations, garages, self-service automobile washers, autobody facilities, and other public wash racks where vehicles are washed shall install catch basins in conformity with the plumbing code in accordance with a permit obtained from the building official. In the event any existing premises do not have a catch basin and the sewer line servicing the facility stops up due to grit or slime in the sewer lines, then the owner or operator of such premises shall be required to modify these facilities to construct a catch basin as a condition of continuing use of the system. No stormwater shall be diverted to these catch basins. No wash rack waste shall be diverted into the stormwater system. See also the requirements for vehicle wash facilities contained in Section 15.17.040. (Ord. 2472 NCS §2 (part), 2013; Ord. 2282 NCS §3 (part), 2007.)
