CITY COUNCIL AGENDA REPORT
MEETING DATE: DECEMBER 9, 2013
AGENDA #: 5F
PREPARED BY: PETE YOUNG, WATER RESOURCES ENGINEER
PRESENTED BY: PETE YOUNG
AGENDA ITEM: CONSIDER APPROVAL OF A RESOLUTION APPROVING THE MS4
SWPPP APPLICATION
DISCUSSION: Introduction
The purpose of this agenda item is to update the City Council on the City's
Municipal Separate Storm Sewer System (MS4) Stormwater Pollution
Prevention Program (SWPPP) Application for Reauthorization ("SWPPP
DocumenY') and MS4 permit coverage status. Staff has prepared a draft
SWPPP Document and is requesting approval to apply for permit coverage
under the updated MS4 permit.
Hi StOry
An MS4 is a system of conveyances (pipes, catch basins, curb/gutter,
ditches, etc.), owned or operated by a public body (such as a city), that
discharges to public waters. It is designed or used to collect or convey
stormwater, does not include sanitary sewer discharges, and is not part of
a publically owned wastewater treatment facility. The City of Prior Lake
operates a regulated MS4, as designated by the Minnesota Pollution
Control Agency (MPCA).
Authority to administer the MS4 program is delegated from the
Environmental Protection Agency (EPA) to the MPCA. Under the MS4
program, stormwater discharges are regulated through the use of a
National Pollutant Discharge Elimination System (NPDES) Permit. The
NPDES Permit ("Permit") is a legal document, and according to this Permit,
the City is required to develop a SWPPP Document that is used to apply
for Permit coverage.
The City obtained Permit coverage and developed Best Management
Practices (BMPs) to meet conditions of the previous Permit (effective 2006-
2013). The MPCA approved a new statewide Permit that became effective
on August 1, 2013. The new permit has more specific requirements for
attaining compliance. Under the Permit, all regulated MS4s (including the
City of Prior Lake) must re-apply for Permit coverage by submitting an
updated SWPPP Document. Within the document the BMPs must be
evaluated for compliance with the new Permit.

The SWPPP Document outlines the City's MS4 program and gives
timelines for updating the program so that it will meet updated MS4 Permit
requirements. The program must address the six minimum control
measures along with any applicable TMDLs. The six minimum control
measures are:
1. Public Education
2. Public Participation
3. Construction Site Runoff Control
4. Post Construction Site Runoff Control
5. Illicit Discharge Detection and Elimination
6. Good Housekeeping.
The City of Prior Lake must submit its SWPPP Document to the MPCA by
December 30, 2013.The following website contains additional information
on the MS4 program:
http://www. pca. state. m n. us/index. php/water/water-types-and-
programs/stormwater/municipal-stormwater/municipal-separate-storm-
sewer-systems-ms4. html
Current Circumstances I
Staff has reviewed the MPCA's Permit requirements and has completed
the SWPPP Document. A copy of the document is attached to this agenda
item. The Lakes Advisory Committee (LAC) reviewed and approved the
SWPPP Document at its November 19, 2013 meeting.
The Minnesota Cities Stormwater Coalition (MCSC), a fee-based League
of Minnesota Cities service, has provided member cities with information
and recommendations relating to the SWPPP Document. The City of Prior
Lake is a member of the MCSC. The MCSC has provided the following
guidance regarding the current application process:
"It is expected that your regulatory mechanisms and current SWPPP BMPs
will not be in compliance with the new permit at this time. You should not
hesitate to answer many of the questions on the SWPPP Document Form
with "No". In many cases, that will be the correct, appropriate, and
expected answer. For each "No" response, you will just need to provide
information about the process you will follow to develop the new SWPPP
and BMP materials and language to meet the new permit requirements
within the schedule."
As outlined in the draft SWPPP Document, the City of Prior Lake's M84
program met the previous requirements (in effect from 2006-2013) but
program updates are needed so that the City's MS4 program meets the
new Permit requirements. Specifically, regulatory mechanisms relating to
illicit discharge detection and elimination (IDDE), volume control, and
erosion/sediment control will need to be addressed. Over the next few
months City staff will review current ordinances and other policy
documents such as the Public Works Design Manual and determine how
these documents can be updated so that the City can meet Permit
2
requirements. In addition, the new Permit requires official regulatory
mechanisms that show how the City meets certain permit requirements. In
most cases the City is already meeting these Permit requirements but
there is not an official written procedure outlining how the requirements are
being met. Staff will use the final SWPPP Document as a guide for
updating the City's MS4 program.
Conclusion
Substantive changes need to be made to the City's MS4 program in order '
to bring it into compliance with the new MS4 Permit. The City was in
compliance with the previous MS4 Permit that expired on July 31, 2013.
The new MS4 Permit, effective August 1, 2013, contains new and updated
requirements. By submitting the attached SWPPP Document by December
30, 2013, the City will be applying for coverage under the new MS4 Permit.
After MPCA has reviewed and tentatively approved the SWPPP Document,
it will be placed on public notice for 30 days. After the public notice process
has been completed, the City will receive a letter that states the date when
Permit coverage begins. The City must be in full compliance with the terms
of the Permit within 12 months of the date Permit coverage begins. It is
anticipated that Permit coverage will begin in 15-18 months.
ISSUES: By submitting the SWPPP Document as proposed, the City Council would
be committing to the following major efforts (as required by the MS4
Permit) within the next 15-18 months:
1. Approving three new ordinances (Illicit Discharge, Erosion &
Sediment Control, and Stormwater Management). These
ordinances will form the basis for required regulatory mechanisms.
To save staff time and to increase consistency with other cities,
available model ordinances should be a starting point.
2. Revising the Public Works Design Manual to include updated
technical details that comply with MS4 Permit requirements.
3. Creating Enforcement Response Procedures (ERPs) to document
how the City will enforce and compel compliance with the updated
regulatory mechanisms.
While there is no question that we all wish to protect the environment and
in the case of Prior Lake, our many lakes, these requirements represent an
unfunded mandate. The entire process is such that we really do not know
what our financial or staffing obligations will be until after we submit our
application and it is "approved" assuming we take the actions imposed
therein. Ultimately the implementation of these requirements are paid by
our residents either as a user charge tax levy or both. There are 115 other
MS4 cities in Minnesota currently facing the same application process.
These facts notwithstanding, we must apply for the new MS4 SWPPP in
order to continue the operation, maintenance expansion and improvement
of our stormwater management system.
3
Finally, our customers whether developers, residents or tenants will face
additional requirements and consequently costs and delays as they work to
develop or improve property. As the enforcer of these requirements it
should be no surprise that the city is seen as more regulatory and less
development friendly.
FINANCIAL Considerable staff resources will be required to bring the City's MS4
IMPACT: program into compliance with the new MS4 Permit. Ensuring compliance
with State MS4 Permit requirements is one of the primary job duties of the
City's Water Resources Engineer and therefore the work will be completed
in-house. Funds for staff resources related to the City's MS4 program are
identified in the Water Quality budget (Stormwater Utility).
ALTERNATIVES: 1. Adopt the attached resolution approving the SWPPP Document (MS4
SWPPP application).
2. Table this item for a specific reason.
3. Deny this item for a specific reason and provide staff with direction. �

maintenance on all mitigation projects of this part.
f. If the permittee receives payment from the owner and/or operator of a construction activity ❑ Yes � No
for mitigation purposes in lieu of the owner or operator of that construction activity meeting
the conditions for post-construction stormwater management in Part III.D.5.a(2), the
permittee shall apply any such payment received to a public stormwater project, and all
projects must be in compliance with Part III.D.5.a(4)(a)-(e).
5. Long-term maintenance of structural stormwater BMPs: The permittee's regulatory
mechanism(s) shall provide for the establishment of legal mechanisms between the permittee
and owners or operators responsible for the long-term maintenance of structural stormwater
BMPs not owned or operated by the permittee, that have been implemented to meet the
conditions for post-construction stormwater management in the Permit (Part III.D.5.a(2)). This
only includes structural stormwater BMPs constructed after the effective date of this permit and
that are directly connected to the permittee's MS4, and that are in the permittee's jurisdiction.
The legal mechanism shall include provisions that, at a minimum:

wq-strm4-49a • 5/31 / 13 Page 6 of 18
a. Allow the permittee to conduct inspections of structural stormwater BMPs not owned or ❑ Yes � No I ' I
operated by the permittee, perform necessary maintenance, and assess costs for those I
structural stormwater BMPs when the permittee determines that the owner and/or operator
of that structural stormwater BMP has not conducted maintenance.
b. Include conditions that are designed to preserve the permittee's right to ensure maintenance ❑ Yes � No
responsibility, for structural stormwater BMPs not owned or operated by the permittee, when
those responsibilities are legally transferred to another party.
c. Include conditions that are designed to protecUpreserve structural stormwater BMPs and ❑ Yes � No
site features that are implemented to comply with the Permit (Part III.D.5.a(2)). If site
configurations or structural stormwater BMPs change, causing decreased structural
stormwater BMP effectiveness, new or improved structural stormwater BMPs must be
implemented to ensure the conditions for post-construction stormwater management in the
Permit (Part III.D.5.a(2)) continue to be met.

V. Minimum Control Measures (MCMs) (Part II.D.5)
A. MCM1: Public education and outreach
1. The Permit requires that, within 12 months of the date permit coverage is extended, existing permittees revise their
education and outreach program that focuses on illicit discharge recognition and reporting, as well as other specifically
selected stormwater-related issue(s) of high priority to the permittee during this permit term. Describe your current
educational program, including any high-priority topics included:
The City is primarily residential and therefore our public education and outreach program focuses on urbaNsuburban
issues. Starting in 2013, the City formed a partnership with the Prior Lake-Spring Lake Watershed District (PLSLWD) to
deliver the program to our residents. Woricing under an o�cial agreement, PLSLWD and City staff annually develop an
education and outreach plan that meets all MS4 permit requirements for both organizations. The plan identifies high-priority
topics and summarizes the program. It is anticipated that this program will continue throughout the current permit term. A
copy of the annual MS4 education and outreach plan can be found on the City's website: www.cityofprioriake.com/LINK.
2. List the categories of BMPs that address your public education and outreach program, including the distribution of
educational materials and a program implementation plan. Use the first table for categories of BMPs that you have
established and the second table for categories of BMPs that you plan to implement over the course of the permit term.
Include the measurable goals with appropriate timeframes that each BMP category will be implemented and completed. In
addition, provide interim milestones and the frequency of action in which the permittee will implement and/or maintain the
BMPs. Refer to the U.S. Environmental Protection Agency's (EPA) Measurable Goals Guidance for Phase 11 Small MS4s

New in 2013, our Raingarden-in-a-Box initiative provided a
series of 4 workshops (with 47 total attendees), information, and
materials to residents to install their own raingardens. A total of
8 raingardens were installed in the City 2013 as a result of the
initiative. The program is our "foot in the door" for connecting
motivated residents with water resources issues; any water
quality benefits realized from the raingardens is a bonus as the
locations are not prioritized with respect to water quality. This
Rain arden-in-a-Box Initiative initiative will continue durin the current ermit term.
In the past the City has periodically coordinated storm drain
stenciling projects. In late 2012, the City created new guidelines
for stenciling and started actively marketing the program to
volunteer groups. Since late 2012 a total of 44 volunteers have
marked 116 storm drains in priority drainage areas (only areas
with direct drainage to Prior Lake were considered). This
Storm Drain Stencilin ro ram will continue durin the current ermit term.
The PLSLWD, under our shared education/outreach agreement,
coordinates site tours with local residents and government
officials to showcase specific projects and programs. Tours
within the City include an annual boat tour and a projects tour
that includes innovative stormwater management BMPs. City
staff presents information about MS4-related projects during the
tours. The goal is 2 tours per year within the City, with a total of
Site Tours 25 attendees.
The PLSLWD, under our shared education/outreach agreement,
coordinates outreach events to involve local stakeholder groups
such as the PLSLWD's Citizens Advisory Committee, the Prior
Lake Association, the Spring Lake Association, the City's Lakes
Advisory Committee, and other similar groups. The goal is to
build local capacity for volunteers by involving stakeholder
groups. Members of the groups can then become well-informed
advocates for local water quality — when they attend other
community events, they are better able to inform others about
water quality. The goal is to coordinate 3 events per year; 2013
events included an ice-off litter pickup, "Dive the Lake" event,
Communit Events and "Rake for the Lake".
The PLSLWD, under our shared education/outreach agreement,
coordinates the publication of fact sheets, brochures, press
releases, and other information according to an "Education
Calendar" included with our shared education and outreach
plan. This calendar can be revised each year based on past
Publications results and u dated riorit to ics.
The PLSLWD, under our shared education/outreach agreement,
coordinates the use of various social media communication
tools, such as Facebook and Twitter, to connect with members
of the local community and beyond. In addition, the Prior Lake
Cable Access Channel is used to broadcast short public service
announcements and other information, according to the
schedule in the "Education Calendar" — this calendar outlines
Communications Tools the annual oals for communication tools.
City staff recently initiated and actively coordinates a local Water
Resources Consortium (WRC) group consisting of technical staff
from various organizations. Representatives from local
watershed organizations, Scott SWCD, Scott County, the
Shakopee Mdwakanton Sioux Community (SMSC), and LGUs
(cities and townships) meet quarterly to discuss upcoming
projects, potential collaboration opportunities, and other
pertinent water resources topics. The overall goal is to keep an
open dialogue with other organizations in order to reduce
duplication of effort and increase collaboration. Although our
organizations have different education/outreach needs and
target audiences, the WRC helps us to identify collaborative
opportunities where programs overlap. Quarterly meetings will
Re ional Collaboration continue throu hout the current ermit term.

1. The Permit (Part III.D.4) requires that, within 12 months of the date permit coverage is extended, existing permittees shall
revise their current program, as necessary, and continue to implement and enforce a construction site stormwater runoff
control program. Describe your current program:
City code requires that all stormwater runoff and erosion and sediment control structures/procedures conform with the
provisions of the Public Works Design Manual (PWDM) and other State regulations (Subdivision Code, Sections
1004.700 and 1004.800). The PWDM requires that all development that disturbs greater than 1 acre of land must apply for
and comply with the requirements of the construction site NPDES permit. The SWPPP must be reviewed and approved
by the City before an Excavating and Grading Permit may be issued. When coordinating with design engineers, the City
uses checklists and review memos to outline design requirements. Development designs must meet or exceed all
stormwater management and erosion and sediment control requirements before fhey can be approved through the City's
platting process. During the review process the Prior Lake-Spring Lake Watershed District (PLSLWD) is invited to review
and provide comments relating to all projects within their jurisdiction. The City inspects all active development projects
under an agreement with the Prior Lake-Spring Lake Watershed District (PLSLWD). The PLSLWD provides site
inspection services (minumum frequency is weekly), creates inspection reports that comply with current NPDES permit
requirements, coordinates follow-up inspections with City staff, and keeps records of all inspections. City staff coordinates
with contractors and uses the inspection results to compel contractors to comply with NPDES pe►mit requirements.

City code requires that all stormwater runoff controls conform with the provisions of the Public Works Design Manual
(PWDM) and other State regulations (Subdivision Code, Section 1004.800).The PWDM requires rate and volume control
for all development, redevelopment, or change in use that creates more than 3, 500 square feet of new impervious area
and disturbs more than 10, 000 square feet of land. When coordinating with design engineers, the City uses checklists
and review memos to outline design requirements. Development designs must meet or exceed all stormwater
management requirements before they can be approved through the City's platting process. During the review process
the Prior Lake-Spring Lake Watershed District (PLSLWD) is invited to review and provide comments relating to all
projects within their jurisdiction.

1. The Permit (Part III.D.6.) requires that, within 12 months of the date permit coverage is extended, existing permittees shall
revise their current program, as necessary, and continue to implement an operations and maintenance program that
prevents or reduces the discharge of pollutants from the permittee owned/operated facilities and operations to the small
MS4. Describe your current program:
The City has an extensive operations and maintenance program in place that serves to prevent or reduce the discharge of
pollutants from City owned/operated facilities and operations. In addition to annually inspecting at least 20% of all ponds
and outfalls within the storm sewer system, City staff also annually inspects structural stormwater BMPs and basic
stormwaterinfrastructure (inlets, catch basins, pipes, manholes, etc.). Detailed GIS maps and inspection records are kept
and maintenance projects are prioritized based on a standardized rating system. Maintenance of the storm sewer system
must be prioritized and implemented in order to keep up with system aging and to ensure that failing system elements do
not threaten overall water quality. The Cify also implements a targeted street sweeping program with the goal of preventing
excess sediment and nutrients from entering the sfoirn sewer system. Areas are targeted for enhanced street sweeping
based on canopy cover, connectivity to surface water (location in the treatment train), and location within priority areas (for
example, areas that drain to an impaired waterbody).
