Stormwater Web Page
The Environmental Health and Safety (EH&S) stormwater web page, consisting of stormwater facts and
information, the stormwater hotline telephone number, and a stormwater survey is currently being
evaluated for substantial improvements and modifications for 2013.
Stormwater Hotline
The stormwater hotline received seven (7) calls related to stormwater activities on campus; six (6) of the
calls pertained to off-site tracking of disturbed soil onto local roads. EH&S staff responded to the calls,
ultimately directing mediation of the off-site tracking.
One (1) call was the result of a student washing a car in a parking lot at Schilletter Village. EH&S
provided stormwater educational materials to the students living in Department of Residence facilities.
Stormwater Management Committee
Iowa State University’s Stormwater Management Committee held no formal meetings in 2012.
However, communications with team members occurred periodically via e-mail and telephone
concerning stormwater policies and project sites.
Pesticide and Fertilizer Management Program
Iowa State University departments that apply pesticides and fertilizers continue to operate according to
defined management programs. The university follows proper storage procedures, and meets guidelines
for training certified applicators, minimizing application rates, and maintaining application records.
Annual reviews determine best management practices and minimization of pesticides and fertilizer
application usage.
Campus Engagement and Volunteer Participation
Iowa State University has a significant level of student, faculty and staff involved in a variety of activities
that directly or indirectly support water quality. In 2012, Iowa State University began identifying those
activities and requested information regarding levels of participation. Examples of clubs, projects and
activities include: Skunk River Navy (water way clean up), Keep Iowa State Beautiful (Adopt a Campus
area program), VEISHEA Service Day (Stash the Trash), Frederiksen Court Community Council (Clean-up
Day) and Live Green Initiative (College Creek Clean Up activity).

Memorial Union Green Roof Project
The Iowa State University Memorial Union (MU) took a step toward sustainability with the installment of
a green roof on the second floor of the MU across from the Multicultural Center.
More than 50 students and volunteers helped with the installation of the roof, including members of the
Iowa State University Horticulture Club, Iowa State University Landscape Club, and The Green Umbrella
Group.
Scott Maas, Memorial Union’s assistant director of hospitality services said, “Although this roof is small,
the main purpose of it is to educate students, staff and the public on why green roofs are good to
consider for our future, and they help to beautify our campus more.”
The benefits associated with installing a green roof include: reducing the amount of water runoff,
extending the life of the roof membrane, lowering the heat island effect, reducing noise in the building,
conserving energy and adding an aesthetic touch to the rooftop.
Research by horticulture students will determine if any future plants will be added to the roof.

TRAINING AND DEVELOPMENT
Members of the Stormwater Committee, EH&S, and Facilities Planning and Management (FP&M) Design
and Operations group participated in programs to improve stormwater management knowledge.
Professional development included: EH&S staff training FP&M Project Managers and Construction
Managers regarding changes to General Permit No. 2; and EH&S and FP&M staff attending workshops
presented by the Iowa Association of Municipalities (IAMU) regarding construction site SWPPPs and site
inspections. Training opportunities are continuously reviewed and will be utilized as time and budgets
allow.
AN ESTIMATE OF THE PREVIOUS FISCAL YEAR EXPENDITURES FOR IMPLEMENTATION OF THE
MANAGEMENT PROGRAM AND THE BUDGET FOR THE CURRENT FISCAL YEAR
The stormwater management budget for calendar year 2012 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 $50,000.

EH&S conducted inspections of all permitted construction sites. EH&S staff conducted 385
weekly site inspections and 94 post rain event inspections, totaling 479 stormwater site
inspections for 2012. Total expenditures for 479 inspections were $43,110.

EH&S staff maintained and evaluated upgrades to the stormwater website, maintained a
quarterly stormwater hotline advertisement in the student newspaper, attended stormwater
training conferences, and developed Iowa State University staff training programs.

FP&M expenditures associated with stormwater project design/BMP, support, implementation
and maintenance were approximately $2,080,000
Total estimated expenditures were $2,177,110. No annual amounts are appropriated for ISU
stormwater management. Stormwater expenses are funded on an as-needed basis.

SUMMARY DESCRIBING THE NUMBER AND NATURE OF INSPECTIONS , ENFORCEMENT ACTIONS
AND PUBLIC EDUCATION PROGRAMS CONDUCTED DURING THE REPORTING PERIOD
Permitted Site Inspections by ISU Staff
EH&S conducted 479 site inspections in 2012; 385 were weekly inspections and 94 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 determined if contractors were following
BMPs as described on the site-specific Stormwater Pollution Prevention Plan. EH&S and FP&M staff
coordinated mitigation efforts with site contractors if deficiencies were noted.
Iowa State University discontinued rain event inspections on October 1, 2012 due to changes in general
permit No. 2. An MS4 permit modification reflecting the regulatory changes was issued to ISU by IDNR
on September 17, 2012. Iowa State University continued weekly inspections (at minimum every 7 days)
of all construction sites permitted under General Permit No. 2.
Outfall Inspections by ISU Staff
Iowa State University conducted its annual dry flow inspection of MS4 campus stormwater outfalls
during November, 2012. EH&S employees visually inspected stormwater outfalls to public waterways.
Dry land outfalls were visually inspected and no illicit discharges were detected. A review of the annual
outfall inspection process was conducted; no changes were administered to the inspection program.
FP&M continued to inspect the stormwater MS4 and conducted repairs as needed. Data is maintained in
the FP&M computerized work management system, FAMIS.
Notices of Discontinuation
Nine (9) construction projects reached final stabilization as defined in General Permit No. 2. The Notices
of Discontinuation were submitted to IDNR. Iowa State University had eight (8) active permitted sites at
the end of 2012.
IDNR Inspections
Iowa State University received one (1) Notice of Violation (NOV) associated with construction activities.
During the first week of May, EH&S staff discovered that an existing soil stock pile near Frederiksen
Court appeared to exceed one acre of disturbed area. Since the project had already potentially
exceeded one acre without a permit, the Iowa Department of Natural Resources (IDNR) conducted an
investigation on May 4, 2012.
During the inspection it was confirmed the Fredericksen Court stock pile exceeded one acre in size; an
NOV was issued as a result of the findings. A permit was obtained for the Fredericksen Court stock pile
(IA-3857-3698). The permitted site reached final stabilization and was closed on 06/26/2012.

Stormwater Education Program
EH&S developed training for Iowa State University employees with the potential to impact stormwater
quality during normal work activities. During the 2012 calendar year, 189 Iowa State University
employees received education on stormwater and what each employee can do to improve stormwater
quality.
Training cycles for employees is on a three year rotation; a large number of ISU employees will be
retrained in 2014.
SUMMARY
All permit required activities for the 2012 reporting period were completed on or before specified
deadlines. It is estimated that the cost of compliance activities completed during calendar year 2012
exceeded $2,177,110. Iowa State University will continue to evaluate opportunities to improve
stormwater quality. Individuals with questions, comments or concerns about stormwater quality issues at
Iowa State University should contact Steve Mayberry, Environmental Specialist III, Iowa State University,
Department of Environmental Health and Safety, 2809 Daley Drive, Ames, Iowa 50011-3660.
