Indiana University Indianapolis
OP-22: Rainwater Management

IUPUI is considered as a municipal separate storm sewer systems (MS4) area under the US EPA Phase II stormwater program. IUPUI is a co-permitted on the City of Indianapolis Phase I Stormwater Permit. The University has developed a Stormwater program that is compliant with the requirements specified by the Indiana Department of Environmental Management and the City of Indianapolis. IUPUI reports compliance efforts to the City of Indianapolis and the Indiana Department of Environmental Management annually. The stormwater program applies to areas of new construction (erosion control and conveyance and treatment design criteria) as well as ongoing campus operations.

The Low Impact Development (LID) practices are implemented by IU Capital Planning and Facilities in accordance with LEED standards implemented for all new and significant renovation projects.

Green infrastructure and LID practices at IUPUI include: - Bioswales along the Cultural Trail and some parking lots - Permeable pavement in one campus location - Rainwater capture cisterns under two buildings (Glick and SELB) - 4 Rain Gardens added in 2020 with the opening of Innovation Hall

Indiana University Environmental Health and Safety (IUEHS) has developed the Stormwater Protection Program to identify the requirements of The National Pollutant Discharge Elimination System (NPDES) Stormwater Program in accordance with the Clean Water Act, Chapter 402(p) regulated by the United States Environmental Protection Agency.

IUPUI adheres to IDEM Rule 5 which can be found here: https://www.in.gov/idem/stormwater/2331.html

IUPUI is required to develop a stormwater program consistent with the Schedule as presented by the City of Indianapolis. Key elements of the program include: - Pollution Prevention, Operations, and Maintenance Document Maintenance of Structural Controls Drain Marking Program Street Sweeping Program Winter Weather Salt Use Roadside Erosion and Litter Control Vehicle and Equipment Wash Area Study/Modifications Pesticide and Fertilizer Application Staff Education and Training Program SOP Inspection and Cleaning of University-Owned Parking Lots SOP Inspection and Cleaning of University-Owned Vehicle Maintenance Garages Flood Control Projects Post Construction Stormwater Run-off Control In New Development and Redevelopment - Illicit Discharges and Improper Disposal Inventory Outfalls and MS4 (Municipal Separate Stormwater System) Summarize Used Oil and Toxics Program - Construction Suite Run-of Control Compliance with Rule 5 / Chapter 600 Construction Site Inspection Program Training Program for Construction Site Inspectors -Public Participation and Education Encourage Public Reporting of Problems Educate Students/Staff about NPS Pollution - Reporting requirements Provide Information to Indianapolis Department of Public Works for Annual Reports In addition to those responsibilities identified in Section 2 of the Stormwater Protection Program, the following are agreed upon responsibilities of the IUPUI Campus Facility Services. - Structural Stormwater Controls (SSC) Maintain map of stormwater conveyances on campus which includes structural stormwater controls (SSC), stormwater inlets and outfalls. (Utilities) Develop and maintain a preventative maintenance (PM) schedule for each SSC. Ensure that preventative maintenance is provided according to established PM schedule. (Building Maintenance) - Street Sweeping Develop and maintain campus street sweeping plan. (Grounds) Document street sweeping events and document amount of material removed. (Grounds) - Winter Weather Salt Use Develop/maintain salt application rates for campus. (Grounds) Document amount of salt applied annually. (Grounds) - Roadside Erosion and Litter Control Develop/maintain plan for identifying areas of erosion on campus (Grounds, Building Maintenance) Document repairs completed annually. (Grounds, Building Maintenance) Document amount of liter collected annually from along campus thoroughfares. (Grounds, Building Maintenance) - Pesticide and Fertilizer Use Prepare a campus pesticide application plan. Ensure that applicators are properly trained and certified. (Grounds, Building Maintenance) - Inspection and Cleaning of University Parking Lots Inspect and clean campus parking lots according to Parking Lot SOP. (Grounds, Building Maintenance) Document amount of litter collected annually from campus parking lots. (Grounds, Building Maintenance) - Flood Control Projects Evaluate water treatment controls structures within the MS4 areas for efficiency as a SSC. (Utilities) Develop feasibility plan for updating SSC’s which do not meet current sediment removal efficiency standards as necessary. (Utilities) Storm drain markings - Creates awareness regarding storm water runoff Operation and maintenance of storm water infrastructure, including quality units (SQU's) or (BMP's) - Reduces harmful storm water runoff through data collection and proper management of runoff 2019 marked the 15th year of active participation as a co‐permittee with the City of Indianapolis for the IUPUI campus. The campus has submitted a compliance report each year to the City of Indianapolis which in turn forwards a comprehensive report to the Indiana Department of Environmental Management. To date, we have not be made aware of any regulatory deficiencies in the campus stormwater program. 

IUPUI has implemented structural stormwater controls to reduce the pollutant load of campus stormwater runoff but currently does not have systems in place to reduce the quantity of runoff.
