Iowa State University had four (4) active permitted sites at the end of December 31, 2008. Storm Drain Markers Iowa State University Environmental Health and Safety (EH&S) and Facilities Planning and Management (FP&M) developed a voluntary storm drain intake marker program which included a The ISU water Quality Club. Student volunteers installed approximately 400 markers in 2008. The goal of the voluntary storm drain marker program was to install approximately 1,000 metal disks on storm drain intakes by summer of 2008. ISU achieved the goal. The disks are stamped metal which read, No Dumping Drains to Stream, and include a fish symbol in the center of the disk.

3 3.0 A SUMMARY OF ALL REVISIONS TO THE APPROVED MANAGEMENT PROGRAM No permit revisions were requested during Calendar year 2008. ISU EH&S submitted NPDES MS4 permit renewal documents as required for a new 5 year permit beginning in February 2009. 4.0 A SUMMARY OF THE DATA, INCLUDING MONITORING DATA, WHICH IS GENERATED WITHIN THE REPORTING PERIOD, INCLUDING NARRATIVE DESCRIPTION OF STORMWATER QUALITY IMPROVEMENTS OR DEGRADATION Stormwater Web Page The EH&S stormwater web page, consisting of stormwater facts and information, the stormwater hotline telephone number, and a stormwater survey, was viewed 385 times in 2008. A total of 181 members of the campus community participated in the stormwater survey during 2008. Stormwater Hotline The stormwater hotline received 8 calls during 2008. Two calls reported concrete trucks washing out on asphalt, 3 calls reported nuisance soil tracking off the ISU Hach Chemistry construction site and 3 calls reported soil tracking off site from ISU Biorenewables Lab construction site. A City of Ames official called to stop trucks hauling loads of soil off site from the ISU Biorenewables due to offsite tracking from the project site through Lincolway in Campus Town. All unacceptable stormwater management practices were halted and immediate on-site training was provided to the parties involved.

4 New Capital Improvement Iowa State University has implemented multiple new capital improvement projects with targeted BMP s. Additional projects are in planning and design (Attachment C).

The Iowa State University Stormwater Committee held three meetings in 2008.

5 Training and Development As part of the continued training and professional development of university staff responsible for stormwater management, members of the Iowa State University Stormwater Committee, EH&S staff, and FP&M Design and Operations staff participated in programs to improve knowledge of stormwater management. Programs include EH&S training of the Stormwater Management Committee, FP&M Utility s staff and managers, Iowa State University Golf Course and Athletic Department grounds crews, and other EH&S staff members. FP&M landscape architects have established a Learning Circle on Riparian Landscapes that focuses on stream environments and explores management practices and opportunities to improve Iowa s waterways. EH&S and FP&M staff attended workshops presented by the Iowa Association of Municipalities (IAMU) regarding construction site SWPPPs and site inspections. EH&S staff attended an additional workshop on Construction Site Erosion and Sediment Control at the IAMU as well the Annual Stormwater Conference in Des Moines. Training opportunities are continuously reviewed and will be utilized as time and budget allow. 5.0 AN ESTIMATE OF THE PREVIOUS FISCAL YEAR S EXPENDITURES FOR IMPLEMENTATION OF THE MANAGEMENT PROGRAM AND THE BUDGET FOR THE CURRENT FISCAL YEAR The stormwater management budget for calendar year 2008 was funded, as needed by several campus entities. EH&S dedicated ½ full time equivalent (FTE) of staff time to stormwater activities. Salary and benefit expenses are estimated to be approximately $40,000. EH&S conducted inspections of all permitted construction sites. A total of 294 site inspections were performed. In addition to inspections, EH&S staff maintained and developed upgrades of the stormwater website, maintained a stormwater hotline advertisement in the student newspaper, attended stormwater training conferences, and developed Iowa State University staff training programs. Costs associated with stormwater project design and training were approximately $255,000. Additional project costs associated with construction of bioswales, roof drain capture, bioretention and a stormwater master plan were estimated at $70,000. ISU also experienced costs associated with project compliance of BMP s on permitted construction sites; maintenance management issues on construction sites totaling approximately $ 250,000. ISU spent an additional 250,625 on street sweeping, work orders for labor, sod, seeding, reseeding, hydro seeding, storm drain installation, mulch and fabric coverings, etc.

6 Total expenditures for fiscal year 2008 were $865,625. No annual amounts are appropriated for ISU stormwater management. Stormwater expenses are funded on an asneeded basis. 6.0 SUMMARY DESCRIBING THE NUMBER AND NATURE OF INSPECTIONS, ENFORCEMENT ACTIONS AND PUBLIC EDUCATION PROGRAMS CONDUCTED DURING THE REPORTING PERIOD Inspections EH&S conducted 294 site inspections in 2008. 236 were weekly inspections and 58 were post rain event inspections. Inspections were conducted by EH&S on all Iowa State University construction sites requiring an NPDES General Permit No. 2. The inspections verified contractors were following specified BMP s as provided on the site-specific Stormwater Pollution Prevention Plan. Iowa State University conducted its annual November dry flow inspection of all campus stormwater outfalls. EH&S employees visually inspected all stormwater outfalls to public waterways listed in the university database. The visual inspection involved walking streams on campus in order to verify there were no illicit discharges. All dry land outfalls were visually inspected. No illicit discharges were detected. Notices of Discontinuation Six construction projects reached final stabilization as defined in the permits and Notices of Discontinuation were submitted to IDNR. Iowa State University had four (4) active permitted sites at the end of 2008. Iowa State University was not subject to any stormwater enforcement actions during the 2008 reporting period. IDNR Compliance Inspections There were no IDNR inspections conducted during 2008. Stormwater Education Program EH&S developed training for Iowa State University employees who could potentially impact stormwater quality functioning during normal work activities. During the 2008 calendar year, 388 employees received education on stormwater and what each employee can do to improve stormwater quality.
