2017 SWPPP Annual Meeting
I. Introduction
Required by National Pollutant Discharge Elimination System (NPDES)
➢ Regulated by Minnesota Pollution Control Agency
City Adopted a Storm Water Pollution Prevention Program (SWPPP)
➢ Goal: Reduce the discharge of pollutants into receiving waters to the
Maximum Extent Practicable (MEP)
➢ Current permit expires July 31, 2018. Updates Needed
Il. Six Minimum Control Measures
1. Public Education and Outreach
Goal - Reduce pollutants and improve water quality by educating the
public, city officials, and city staff about the impacts on stormwater runoff.
Activity —Distribute literature on fertilizer, chlorinated pool discharges,
automotive liquids, pet waste, construction activities, etc.
Updates needed — Implementation Plan (attached)
2. Public Participation and Involvement
Goal —Allow public to provide input on the City's SWPPP
Activity —Annual public meeting
Updates needed —None
3. Illicit Discharge Detection and Elimination
Goal — Reduce / eliminate non-stormwater discharges into the storm
sewer system and receiving waters.
Activity - Identify illicit discharges through inspections of the storm sewer
system (i.e. idents dry weather discharges, staining, odors)
Updates Needed — Training for all field staff, identification of priority
areas, and written emergency response procedure (ERP) (attached)

4. Construction Site Stormwater Runoff Control
Goal —Reduce sediment and erosion by implementing standards and
enforcing through inspections. Require waste controls for site operators.
Updates Needed — written procedures for identifying priority sites for
inspection and written ERP (attached)
5. Post -Construction Stormwater Management
Goal — Reduce pollutants in stormwater discharges by implementing
permanent stormwater facilities, such as NURP ponds and treatment
structures. Implement standards to ensure permanent BMP's are installed
and maintained for new development and re -development.
Updates Needed — Update Ordinance to comply with permit and written
ERP (attached)
6. Pollution Prevention / Good Housekeeping
Goal — Reduce pollutants in stormwater discharges by employing good
housekeeping practices for municipal/public works operations.
Activity — Street sweeping, pond, outfall and structure inspections,
stockpile and handling area inspections, maintenance, repairs, etc.
Updates Needed — none
III. Upcoming Challenges
➢ Current permit expires July 31, 2018.
➢ Stage 2 will likely include a survey of all NURP ponds and evaluation of
treatment capacity. City will eventually be required to dredge / maintain
ponds as they fill up with sediment (expensive).
Impaired Waters / Total Maximum Daily Load (TMDL) — Requires
implementation by City after TMDL Plan is approved.
Mississippi River — Mercury in fish tissue, Polychlorinated biphenyls in
fish Tissue (2011)
Crow River — Fecal Coliform (2012), Fish bioassessments (2017),
Turbidity (2012), Dissolved Oxygen (2015)
➢ Funding — Adjustments to Storm Water Utility Fee may be required as actual
costs are calculated and potential additional costs are determined.

2017 SWPPP Annual Meeting
➢ Management — May want to evaluate regional ponding vs. small development
ponds. Regional ponding could provide large future cost savings when the
costs of inspections, maintenance, and dredging are considered.
