Operations and Maintenance Manual

The policies set forth in this section are intended to meet the requirements that the City address pollutants of concern in local stormwater runoff and comply with narrative standards in the permit. The water quality management program of the City of Indianapolis is performance-based. In a performance based program it is essential that any approved BMP be properly maintained to ensure that the BMPs perform as designed. An O&M Manual for any approved BMP will be required (see Section 102.06). As will be stated in the O&M Manual, maintenance will be the responsibility of the property/BMP owner. The City encourages the use of high-efficiency, low maintenance BMPs that have the potential for removal of multiple stormwater pollutants.
BMPs defined in Chapter 700 of this Manual as being capable of meeting the specified performance criteria for pollutant removal will be acceptable if designed to the standard specifications in Chapter 700 of this Manual.
