A. Surface Cleaning, Parking Lots and Similar Structures. Persons owning or operating a paved parking lot, gas station pavement, paved private street or road, or similar structure or conducting routine building or surface wash downs shall clean and maintain those structures consistent with the City of Bend’s Illicit Discharge Manual, which shall serve as regulations implementing this title and may be amended by the City Manager. Compliance with the manual is required prior to any discharge to a storm drain, dry well or drill hole.

B. Covered Parking Garages. All water from nonstormwater sources or incidental stormwater sources (i.e., blown in through openings and windows or transported on vehicles) that enters newly developed or significantly redeveloped covered parking garages is to be directed to the sanitary sewer disposal system unless that alternative is not reasonably feasible. Newly developed or significantly redeveloped covered permanent parking garages may drain into a storm drain when no feasible alternative is available, with the consent of the owner and operator, and with proper pretreatment and maintenance accessibility in accordance with this title and State and Federal regulations.

C. Outdoor Storage Areas – Commercial and Industrial Facilities. In outdoor areas, no person shall store grease, oil or other hazardous substances in a manner that will or may result in such substances entering a storm drain facility. In outdoor areas, no person shall store motor vehicles, machine parts, or other objects in a manner that may leak grease, oil, or other hazardous substances to a storm drain facility. To prevent the discharge of hazardous substances to the public or private storm drainage systems, the City may require the installation of a spill containment system. Spill containment systems may consist of dikes, walls, barriers, berms, or other devices as required. No person shall operate a spill containment system such that it allows incompatible liquids to mix and thereby create a hazardous condition. [Ord. NS-2176, 2012]
