Consent Business 4. C. 3.
SHAKOPEE
TO: Mayor and City Council
Mark McNeill, City Administrator
FROM: Joe Swentek, Engineer
DATE: 11/19/2013
SUBJECT: Approval of the MS4 SWPPP Application for Reauthorization to the MPCA (E)
Action Sought
Approve a motion to approve the MS4 SWPPP Application for Reauthorization to the MPCA to
obtain permit coverage under the NPDES permit program.
Background
Attached is the Municipal Separate Storm Sewer System (MS4) Storm Water Pollution
Prevention Program (SWPPP) Application for Reauthorization to the Minnesota Pollution Control
Agency (MPCA), which includes detailed information necessary to obtain the required coverage
under the National Pollutant Discharge Elimination System (NPDES)permit program.
The NPDES permit program is a mandate set forth by the Environmental Protection Agency's
(EPA) Clean Water Act and it is administered by the MPCA. The goal of this permit, according
to the MPCA, is to "reduce the amount of sediment and pollution that enters surface and ground
water from storm sewer systems to the maximum extent practicable". Ultimately it gives the City
of Shakopee, an owner and operator of a MS4, the approval to discharge storm water to lakes,
rivers and wetlands.
The program has been in existence since 2003 and each permit cycle is effective for five (5)years,
at which time each MS4 must apply for reauthorization. The City of Shakopee did so in 2008 and
now we must do it again in 2013. However, this year's application is much more detailed and
involved. Attached is a memo from WSB &Associates, Inc outlining the significant changes and
potential impacts of the new permit. WSB & Associates, Inc. was authorized to aid City of
Shakopee staff to ensure we are in compliance with the new rules as they have the unique
expertise in this constantly evolving process.
If approved, the application will be submitted to the MPCA and work will begin to gather and
develop the necessary information as set forth in the attached application.
Recommendation
Staff recommends approving a motion to approve the MS4 SWPPP Application for
Reauthorization to the MPCA to obtain permit coverage under the NPDES permit program.
Budget Impact
Unknown at this time, however, there will be additional costs affecting the Storm Drainage Utility
fund.
Relationship to Vision
This supports Goal E: Deliver effective and efficient public services by a staff of well-trained,
caring and professional employees.
Requested Action
Approve a motion to approve the MS4 SWPPP Application for Reauthorization to the MPCA to
obtain permit coverage under the NPDES permit program.

Re: MS4 General Permit Update
WSB Project No. 2092-490
Overview
The City of Shakopee is classified as a city that is required to obtain a Municipal Separate Storm Sewer
System(MS4)general permit. This program began in 2003 and continues on in five year permit cycles.
At the end of each general permit the cycle the MPCA revises the program. The current permit term will
run from August 1,2013 to July 31, 2018.
The MS4 general permit requires municipalities to develop Best Management Practices(BMPs)in a
Stormwater Pollution Prevention Program(SWPPP)that reduce pollutants discharged with stormwater
runoff.The BMPs need to address each of the following major program components,which are known as
Minimum Control Measures(MCMs).
• MCM 1:Public education and outreach
• MCM 2:Public participation
• MCM 3:A plan to detect and eliminate illicit discharges to the stormwater system(chemical dumping
and wastewater connections, etc)
• MCM 4: Construction-site runoff controls
• MCM 5: Post-construction runoff controls
• MCM 6:Pollution prevention and municipal"good housekeeping"measures, (covering salt piles and
street-sweeping,etc.)
Program Changes
The following summarizes each of the major program changes that will need to be met to meet the new
MS4 permit requirements.
MCM 1:
• Prioritized education activities(areas without stormwater treatment, areas discharging to
waterbodies that have degraded water quality)
• Educating the public on illicit discharge(non-stormwater discharge)recognition and reporting
• Documentation of specific information related to this MCM

(major updates to City Code: Section 16, Water Resources Management)
• Local programs must include prohibitions and limitations with regard to infiltrating stormwater
• Mitigation requirements when TSS and Phosphorus cannot be managed on-site
• Legal mechanisms to ensure long-term maintenance of BMPs
• Written procedures for site plan reviews
• Documentation of specific information related to this MCM
MCM 6
• Inventory of facilities that contribute pollutants to stormwater discharges
• Procedures and schedule to determine TSS and TP treatment effectiveness of stormwater ponds
(procedures will help prioritize maintenance)
• Quarterly inspections of stockpiles/storage and material handling areas
• Documentation of specific information related to this MCM
