Senior Engineering Technician Ben Scharenbroich shared an update on the program, saying that about half of the funds in the budget have been used. Scharenbroich indicated the program has
slowed down since June and he is working on social media promotions. Committee Member
Osborne inquired if there is a way to increase the number of commercial properties. Scharenbroich said it has been challenging; there was interest from several townhome associations but few have taken advantage of the program. He will be working with the Economic Development Manger on initiatives to reach out to businesses. Also discussed was installing water sense systems on City-
owned properties to demonstrate the savings to commercial properties.
On another topic, Committee Member Osborne inquired about the status of the Simple Recycling curbside textile recycling program. Water Resources Manager Asche reminded the committee that their previous recommendation was to put out a Request for Proposal (RFP). Asche said that could
be done at any time. He knows of another company, in addition to Simple Recycling, that could
be interested in offering their services to the City, but did not know if both operated their programs the same. He recapped that Simple Recycling’s proposal was of no-cost to the City and included a kick-back to the City of about $2,000/year. He indicated that any other company would need to match that proposal in order to be considered.
Also on another topic, Water Resources Manager Asche shared that he has taken a new position with the City of Maple Grove and this would be his last EQC meeting. He thanked the committee for their hard work over the years and expressed his appreciation for their dedication to serving the City.

CITY OF PLYMOUTH ENVIRONMENTAL QUALITY COMMITTEE
AGENDA REPORT
DATE: October 3, 2018 for Meeting of October 10, 2018
TO: Environmental Quality Committee (EQC)
FROM: Michael Thompson, Director of Public Works
SUBJECT: Storm Water Pollution Prevention Program (SWPPP)
ACTION REQUESTED: Accept Public Comment on the 2017 Storm Water Pollution Prevention Program
INTRODUCTION: Annually the City of Plymouth is required to prepare an annual SWPPP report detailing
progress made in the previous year as required by the MS4 Permit issued through the Minnesota Pollution
Control Agency. As part of that process an annual meeting is required to be held to accept public comment
on this update and those comments would be included with the annual report to the Minnesota Pollution
Control Agency.
BACKGROUND: The Minnesota Pollution Control Agency (MPCA) requires the City of Plymouth obtain
coverage to discharge stormwater outside the City limits under the General Permit to Discharge
Stormwater Associated with Municipal Separate Storm Sewer Systems (MS4) under the National Pollutant
Discharge Elimination System/State Disposal System Permit Program.
The permit requires the City to develop a Storm Water Pollution Prevention Program (SWPPP) consisting
primarily of required minimum control measures as well as specific activities to address impaired waters
with approved Total Maximum Daily Load studies. The City is required to regularly review and update the
SWPPP to determine whether changes may be warranted to the SWPPP to meet the goals of approved
Total Maximum Daily Load Plans.
Plymouth is one of roughly 220 entities in Minnesota covered through the NPDES Phase II Permit Program.
Phase II entities are those with populations ranging from 10,000 to 100,000. The MS4 permit application
requires cities to develop a SWPPP and identifies the minimum control measures (MCM) the SWPPP must
address which include:
• MCM 1 – Public Education and Outreach
• MCM 2 – Public Participation and Involvement
• MCM 3 – Illicit Discharge, Detection and Elimination
• MCM 4 – Construction Site Storm Water Runoff Control
• MCM 5 – Post Construction Storm Water Management
• MCM 6 – Pollution Prevention and Good Housekeeping
This meeting and action on the SWPPP was noticed in the local newspaper on September 27 and October
4, 2018 to allow an opportunity for the public to comment on the City’s SWPPP in accordance with the
public participation and involvement requirement of the MS4 Permit. The published notice also linked
directly to the SWPPP at his link: www.plymouthmn.gov/index.aspx?page=263
As of October 3, 2018 staff has not received feedback on the published SWPPP document on the website.
BUDGET IMPACT: Implementation of the Storm Water Pollution Prevention Program is primarily
supported through the Water Resources Fund which supports operations and capital projects within the
City.
RECOMMENDATIONS: Staff recommends the EQC discuss the SWPPP document and open the floor to
accept public comment on the SWPPP during the meeting. City staff will compile and address comments
and incorporate them in the final 2017 SWPPP report submittal to the MPCA.

INTRODUCTION
Surface water resources such as lakes, wetlands, and creeks are an important component of the quality of life for residents in the City of Plymouth. The Plymouth Storm Water Pollution Prevention Program (SWPPP) promotes citizen involvement and provides a strategy for dealing with the quantity and quality of the water resources in Plymouth.
The City of Plymouth has developed and will implement its SWPPP to reduce the discharge of pollutants from its drainage system to the maximum extent practicable to protect water quality and to satisfy the appropriate water quality requirements of the Clean Water Act. The City is committed to sustainable management of its natural resources and minimum control measures are
listed which will assist the City in attaining its goals. HISTORY
The first recorded settlement in Plymouth was on the east shoreline of Medicine Lake in 1853.
The first major storm drainage improvements were undertaken in Plymouth in the mid 1960s. This initial Storm Drainage Program was subsequently updated with the 1973 Storm Drainage Plan which presented an overall layout of major drainage facilities in Plymouth, including storm sewers, ponding areas, and major drainageways. The main purpose of the 1973 plan was to provide an
adequate and economical means of conveying storm water runoff through Plymouth. The City
completed a revision to the 1973 plan in 1980. The 1980 revisions were based on recent platting and development proposals, storm drainage improvements, and the Land Use Guide Plan. The plan provided information on storm sewer and open channel sizes, storm water flows, pond storage volumes, water levels, and costs.
A major undertaking began by the City of Plymouth in 1995 and 1996 to update its Storm Water Management Plan to include integrated resource management. The focus of the new Plymouth Water Resources Management Plan was to manage and protect both water quality as well as water quantity. The 2000 Water Resources Management Plan established a clear view of existing
conditions, established goals for managing the City’s surface water resources, and set a new
process for public input in developing the plan. In 2008, the City expanded surface water management to include new requirements such as the Minnesota Pollution Control Agency’s Total Maximum Daily Load (TMDL) and Non-Degradation requirements. The 2008 Surface Water Management Plan includes several major elements:
1. Goals and Polices 2. Official Controls 3. Watershed Assessments
Other efforts included Parkers Lake Watershed and Lake Management Plan (1993); Minnesota
Rules 8410, Metropolitan Area Local Water Management Plan (1992); Local Watershed Management Plans; Plymouth Natural Area Survey (1994); Wetland Inventory and Ordinances, (1994); Hennepin County Ground Water Plan (1994); up-date of Erosion Control and Shoreland Ordinances; Phosphate Free Fertilizer Use and Sale Restrictions (1995, up-dated in 2000), Land
Resource Inventory (2006), Non-Degradation Report (2007), TMDL Reports, and establishing and
initiating continuous work on developing educational activities throughout the City.
SWPPP 2017 Page 4 of 64 City of Plymouth
Since the submittal of the first SWPPP in 2003, the City has implemented and initiated many other
projects, such as: 1. The completion of the Phase I & Phase II of Medicine Lake Watershed Management and Implementation Plans. The ultimate goals of these plans were to reduce at least 1000
pounds of phosphorous from the watershed and to implement an aquatic vegetation
management plan to reduce internal loading by at least 15%. 2. Establishing Aquatic Vegetation Management Plans for Medicine, Parkers, Bass, and Schmidt Lakes. 3. Completed implementation of Parkers Lake Management and Implementation Plan
4. Developed and implemented Schmidt Lake Management Plan
5. Developed and implemented Gleason Lake Management Plan 6. Completion of the Hydrologic and Hydraulic study of the 2020 Urban Expansion Area 7. Establishing the Plymouth Pond Maintenance Policy 8. Expanding the Plymouth surface water monitoring program
9. Providing grant funds for area residents for projects that reduce turf grass, incorporate
native plants, or conserve water 10. Studied and adopted an alternative fuel policy 11. Expanded street sweeping program 12. Continued expansive Environmental Education Programs
13. Reviewed, up-dated, and expanded the City’s Goose management
14. Expanded the Purple loosestrife bio-control project 15. Established a Plants, Ponds, and Practices Tour 16. Completed the required Non-Degradation Report 17. Completed various flood protection/erosion repair projects
18. Assisted with development of TMDL and Implementation Plans
19. Participates on the Bassett, Elm, and Shingle Creek watershed technical advisory committees. 20. Supported the Pike Lake Subwatershed Assessment through the Shingle Creek Watershed.
The City is also actively partnering and collaborating with its three watershed joint powers
organizations, one watershed district, the Metropolitan Council, the Minnesota Department of Natural Resources, the Minnesota Board of Water and Soil Resources, and Hennepin County on a variety of different grants, projects, and environmental education.
AREA DESCRIPTION: Location. Plymouth is located in the western portion of the seven county metropolitan area in central Hennepin County Minnesota. It is bounded on the north by Maple Grove, on the east by Golden Valley and New Hope, the south by St. Louis Park, Minnetonka, and Wayzata, and on the west by Orono, and Medina.
Topography. The topography of Plymouth can be described as rolling with isolated marsh lands, swamps, lakes, and steep slopes. Approximately 150 feet in elevation changes varying from 1030 feet above sea level in the west central part of the city to about 880 feet above sea level in the northeastern part of the city. Water drains naturally through most of the city. Approximately 20%
of the City is covered with water. Eight major lakes cover an area of about 1,542 acres with 2,857 acres of wetland areas.
SWPPP 2017 Page 5 of 64 City of Plymouth
Soils. The soil in Plymouth can be generally described as dense clay with few instances of lenses
of mixed sand and gravel. The three basic soil types encountered include sandy clay till from the Des Moines Ice Slope of the Wisconsin Glaciations, natural sand and top soil and organic silt deposits. Bedrock is found between elevations 700 and 800 feet.
Watersheds. Plymouth lies within the larger Mississippi River basin in east central Minnesota.
There are four local watersheds in the City, Shingle Creek, Bassett Creek, Minnehaha Creek, and Elm Creek with 19%, 53%, 16%, and 12% of the city in these watersheds respectively. Growth. Plymouth has experienced rapid but steady growth over the past three decades. In 2010,
the population of Plymouth was 70,576 per the U.S. Census. Both industrial and commercial
sectors have also been growing along with the population growth. The City is almost 85% developed with land use of commercial, industrial, and residential land uses. Climate. The climate is typical of the metro area. The mean annual temperature is 44 degrees
Fahrenheit and the mean monthly temperature varies from 12 degrees Fahrenheit in January, to 73
degrees Fahrenheit in July. The average annual liquid precipitation is approximately 30.5 inches, of which annual average snowfall is 44 inches. SWPPP DEVELOPMENT: City staff attended workshops organized by the League of Minnesota Cities to gather information on how to develop the Storm Water Pollution Prevention Program in accordance with Minnesota Pollution Control Agency’s requirements. The process of self assessment included a number of components:
• staff attended the workshop organized by the League of Minnesota Cities and the Minnesota Pollution Control Agency;
• the City conducted a review of existing ordinances;
• Review and up-date of the existing storm water pollution prevention policies and practices currently in use;
• educational and training programs which focus on storm water pollution prevention were evaluated and reviewed;
• regular internal staff meetings were conducted to discuss collaboration between the existing programs, proposed new programs, to identify any gaps in meeting the requirement of SWPPP, and finally selecting appropriate best management practices to meet the plan’s objectives.
The internal staff meetings have been a major component of the self assessment part of the Plymouth SWPPP. A number of City staff from different departments and divisions have all been actively involved in this process. The group established and identified existing Best Management Practices and looked for areas where the City could improve to maximum extent practicable to
meet the plan’s objectives and requirements. FUNDING MECHANISM:
The City of Plymouth has established a Storm Water Utility fee that is assessed against utility bills. The City’s Storm Water Utility Revenue is generated by fees according to land use. At present, the rate is $5.96 per month per residential parcel, 3.32 times the residential rate for multi-family,
SWPPP 2017 Page 6 of 64 City of Plymouth
and 7.18 times the residential rate for commercial and industrial. Other land uses are evaluated
individually based on the amount of impervious coverage and parcel size. Details on the City’s Storm Water Utility Fee can be found in Section 725 and Section 1015 of the City Code. TOTAL MAXIMUM DAILY LOAD (TMDL) The City of Plymouth is currently subject to 18 water quality impairments (excluding mercury) and seven EPA approved TMDL plans. TMDL implementation plans are expected in the future for each of the other impairments.
A. Shingle Creek Chloride TMDL In 1998, Shingle Creek was listed on the Federal Clean Water Act’s 303(d) list of impaired waters for exceeding the chloride standard for aquatic life. The listing of Shingle Creek as impaired resulted from a limited sampling of chloride completed in 1996 by the US
Geological Survey (USGS) at their discharge monitoring station at the Queen Avenue
Bridge in Minneapolis. After reviewing the USGS data from Queen Avenue, the Shingle Creek Watershed Management Commission (SCWMC) has been sampling routinely for chloride in Shingle Creek. This TMDL was developed to address the 1998 listing for the impairment of aquatic life and recreation based on chloride exceedances.
The City of Plymouth is a stakeholder in the Shingle Creek Watershed. The Shingle Creek Chloride TMDL was prepared by the watershed. Stakeholders in the watershed agreed to work collectively to achieve a 71% reduction in chloride use to achieve the standard understanding that each stakeholder was working under unique financial, public safety and
perception, and feasibility limitations.
The SCWMC will be the lead on the implementation of the Chloride TMDL, however, individual stakeholders (City of Plymouth) will be ultimately responsible for implementing the identified BMPs. Implementation strategies can be found in Table 1.

B. Schmidt, Pomerleau, and Bass Lakes Nutrient TMDL In 2002, Schmidt, Pomerleau, and Bass Lakes were listed on the Federal Clean Water Act’s 303(d) list of impaired waters for aquatic recreation because the lakes exceed the water
quality standard for nutrients. The goal of this TMDL is to quantify the pollutant reductions
needed to meet the water quality standards for nutrients in Schmidt, Pomerleau and Bass
SWPPP 2017 Page 7 of 64 City of Plymouth
Lakes. The Schmidt, Pomerleau and Bass Lakes TMDL has been established in accordance
with Section 303(d) of the Clean Water Act. This TMDL provides waste load allocations (WLAs) and load allocations (LAs) for these three lakes. Based on the State standard for nutrients, the TMDL establishes a numeric target of 40 μg/L total phosphorus concentration for Pomerleau Lake and 60 μg/L total phosphorus for Schmidt and Bass Lakes.
Implementation strategies to meet the goals of this TMDL can be found in Table 2.

C. Cedar Island, Pike, and Eagle Lakes Nutrient TMDL Of the three lakes identified in this TMDL (Cedar Island, Pike, and Eagle), only Pike Lake lies within the City of Plymouth, however, surface water entering Pike Lake will eventually
drain into Eagle Lake. Meeting the goals for Pike Lake is anticipated to meet Plymouth’s requirements for Eagle Lake. No drainage from Plymouth goes to Cedar Island Lake. In 2002, Pike Lake was listed on the Federal Clean Water Act’s 303(d) list of impaired waters for aquatic recreation because the lakes exceed the water quality standard for nutrients. Eagle Lake was added in 2008 for the same reasons. The goal of this TMDL is to quantify
the pollutant reductions needed to meet the water quality standards for nutrients in Cedar Island, Pike, and Eagle Lakes. This TMDL has been established in accordance with Section 303(d) of the Clean Water Act and provides waste load allocations (WLAs) and load allocations (LAs) for these three lakes. Based on the State standard for nutrients, the TMDL establishes a numeric target of 40 μg/L total phosphorus concentration for Eagle Lake and
60 μg/L total phosphorus for Cedar Island and Pike Lakes. Implementation strategies to meet the goals of this TMDL for Pike and Eagle Lakes can be found in Table 3. TABLE 3.

Medicine Lake Excess Nutrient TMDL The Medicine Lake watershed is located in the metropolitan area of the Upper Mississippi
River Basin and includes portions of the cities of Plymouth, Medicine Lake, Minnetonka,
Golden Valley, New Hope, and Medina. The outlet of Medicine Lake is the headwater of Bassett Creek. Medicine Lake is the second largest lake in Hennepin County and is considered the most important recreational water body in the City of Plymouth. The
SWPPP 2017 Page 8 of 64 City of Plymouth
Medicine Lake watershed (nearly 12,000 acres) is fully developed. Runoff from the
watershed enters the lake from creeks, storm sewer outfalls, and culverts at various points along the lakeshore. The volume and pollutant levels of storm water runoff from the watershed, combined with releases of phosphorus from sediments and plants in the lake, result in periods of poor lake water quality. Available data indicates that Medicine Lake
violates the State’s water quality standards. The combination of high phosphorus and high
chlorophyll-a (a measurement of algae growth) supports including Medicine Lake on the Minnesota Pollution Control Agency’s (MPCA) impaired waters list. The Clean Water Act and Environmental Protection Agency (EPA) regulations require
states to develop Total Maximum Daily Loads (TMDLs) for water bodies that are not
meeting water quality standards. The TMDL process establishes the allowable loading of pollutants for a water body. By following the TMDL process, states can establish controls to reduce pollution and restore and maintain the quality of the water resource. Therefore, a TMDL was designed to allow Medicine Lake to meet water quality goals.
The primary water quality target for this TMDL is the average growing season total phosphorus concentration in Medicine Lake. The State standard is 40 μg/L. The City of Plymouth has established a goal of 38 μg/L for Medicine Lake. This TMDL has been developed to meet the 38 μg/L target. The more conservative target of 38 μg/L is
considered an explicit Margin of Safety (MOS) for this TMDL.

E. Shingle Creek & Bass Creek Impaired Biota and Dissolved Oxygen TMDL
The Shingle Creek & Bass Creek Impaired Biota and Dissolved Oxygen TMDL study addresses the dissolved oxygen impairment in Shingle Creek and biotic integrity impairments in Shingle and Bass Creeks, in Hennepin County, Minnesota. The goal of this
TMDL is to quantify the pollutant reductions needed to meet State water quality standards
for dissolved oxygen in Shingle Creek and State Index of Biotic Integrity standards in Shingle and Bass Creeks. The Shingle Creek watershed covers 44.7 square miles in east-central Hennepin County,
Minnesota. Shingle Creek begins at the junction of Bass Creek and Eagle Creek in the City
of Brooklyn Park, flows easterly, then southerly for a total of 11.3 miles before discharging into the Mississippi River in Minneapolis. Bass Creek is the outlet of Bass Lake, and is about 2.4 miles long. Bass Creek is formed at the weir that controls the level of Boulder Ridge Pond, the last in a series of wetlands downstream of Bass Lake. The watershed is
fully developed with dense urban and suburban land uses
SWPPP 2017 Page 9 of 64 City of Plymouth
Shingle Creek has been substantially altered from conditions documented in the 1855
Public Land Survey. A portion was straightened and dredged in 1910 to serve as County Ditch #13. Over time most of the rest of the stream has been channelized, widened and dredged to better convey stormwater discharged to the stream. Bass Creek appears to be an historically intermittent channel too small to be recorded on the Public Land Survey and
then later ditched to drain wetlands and/or provide agricultural drainage, or it was created
to provide those functions. A Stressor Identification study evaluated the potential causes of the impaired biotic integrity of both streams. Potential candidate causes of the impairments that were ruled out
include: temperature, pH, nutrients, turbidity/TSS, and toxic chemicals. Five stressors that
are potential candidate causes were examined in more detail: low dissolved oxygen; altered habitat; loss of connectedness; altered hydrology; and ionic strength, specifically chloride. The evidence for altered hydrology is strongest followed closely by low dissolved oxygen and lack of habitat. While the loss of connectedness and ionic strength are plausible
stressors and are likely contributing to the impairment, there is less direct evidence of their
role. Hydraulic models for Shingle Creek were developed to assess the conditions resulting in persistent low dissolved oxygen. A scenario assessment determined that the likely causes
were low-oxygen discharge from headwaters wetlands and excessive sediment oxygen
demand resulting from the overwide channel. Stream restoration on both Shingle Creek and Bass Creek to create a low-flow channel, add reaeration structures, and enhance habitat and improvements to headwaters wetlands would have the most impact in increasing dissolved oxygen and improving biotic integrity.

F. Lake Hiawatha Nutrient TMDL
A TMDL has been developed for Lake Hiawatha to address a nutrient impairment. Chlorophyll-a or Secchi depth observations coupled with ambient water quality monitoring data indicate that
excess total phosphorus (TP) is causing the impairments in Lake Hiawatha. The City of Plymouth has been allocated a reduction of 19.6 pounds annually. TABLE 5. Lake Hiawatha Nutrient TMDL Improvement Strategies. Implementation Item SWPPP reference Progress Annual Education Appendix A 1.c.1 Annually Street Sweeping Appendix A 6.a.2 Annually G. Upper Minnehaha Creek Watershed Nutrient and Bacteria TMDL This Total Maximum Daily Load (TMDL) study addresses nutrient impairments in twenty lakes and an E. coli impairment in Painter Creek within the Minnehaha Creek Watershed District (MCWD), which is located within the Upper Mississippi River Basin. The City of Plymouth is not
SWPPP 2017 Page 10 of 64 City of Plymouth
affected by the E. coli impairment. The MCWD covers approximately 178 square miles in
Hennepin and Carver Counties, including parts of Minneapolis, Minnesota and its western suburbs. The watershed drains to Minnehaha Creek and ultimately the Mississippi River. The water bodies addressed in this study are located within a distinct hydrologic basin within the MCWD referred to
as the “Upper Watershed,” which drains through agricultural land and suburbs west of Minneapolis to Lake Minnetonka, which outlets into Minnehaha Creek. The goal of this TMDL is to quantify the pollutant reductions needed to meet State water quality standards for nutrients in the lakes and
E. coli standards in Painter Creek. Fifteen of these lakes are defined as deep lakes for which the North Central Hardwood Forest ecoregion numeric water quality standards are a summer average total phosphorus concentration of 40 μg/L, 14 μg/L chlorophyll-a, and greater than 1.4 meter in Secchi depth. The other six lakes are shallow, for which the numeric water quality standards are a summer average total phosphorus concentration of 60 μg/L, 20 μg/L chlorophyll-a, and greater than one meter in Secchi depth. Nutrient budgets were developed for all twenty lakes along with lake response models to set the TMDL and Load and Wasteload Allocations. A robust lake and stream monitoring dataset was available and was the basis of the nutrient budget calculations. Wasteload reductions ranging from
no reduction to a 93 percent reduction and load reductions ranging from no reduction to 79 percent reduction will be necessary to meet water quality standards. TABLE 6.

*BMP Title: Procedure for Site Plan Review
*BMP Description:
The City of Plymouth has established a detailed process for all site plan reviews. All development plans are submitted to the Community Development Department. They are routed to the Public Works Department for review of erosion and sedimentation control measures. Reviews include: erosion control, drainage concerns and implementation of Best Management Practices such as rain
gardens, infiltration basin and green roofs. Approved plans are subject to a pre-construction meeting at which time staff reviews erosion and sediment control on the approved plan and City policies. Prior to issuance of a grading permit, erosion and sediment controls such as silt fence and rock construction entrances are inspected by staff to confirm they are in place. Once project activity has begun, sites are subject to weekly inspections by City staff.
*Measurable Goals:
All development plans are reviewed (100%). Non-development construction is also reviewed when staff has concerns.

*BMP Title: Impaired Waters Review Process
*BMP Description:
The City of Plymouth will review all discharges from our MS4 system to impaired waters, as defined by the current USEPA approved 303 (d) list. For this review the City of Plymouth will
utilize our updated Surface Water Management Plan to: 1. Identify the impaired waters that are likely to be impacted by stormwater discharge 2. Use a combination of storm sewer maps and field surveys to identify all potential
stormwater discharges to impaired waters. 3. Delineate the watershed area that contributes to the discharges 4. Evaluate the hydrology, land use and other characteristics of the watershed areas that may impact the impaired water as a result of a stormwater discharge.
Based on the review above, the City of Plymouth will determine if any changes to the existing stormwater system or BMPs are needed to minimize the impact of discharges from our MS4 to the impaired waters. If modifications are necessary, the City of Plymouth will modify our SWPPP and submit those modifications to the MPCA with the current year’s annual report. In our review, we
will consider timing and long and short term costs. All assumptions, reasoning, and justification used to reach a conclusion on whether or not SWPPP revisions are necessary will be documented in the decision making process.
