PREVENTION PROGRAM PUBLIC MEETING
DISCUSSION:
Historv
The City of Prior Lake is regulated under the NPDES Phase II Small Municipal
Separate Storm Sewer Systems (MS4) permit. This permit requires the City to
implement a Storm Water Pollution Prevention Program (SWPPP) and hold an
annual public meeting to discuss the SWPPP.
The SWPPP requires the City to implement several Best Management Practices
(BMP) on an annual basis. These BMP's include:
A) Public Education and Outreach
B) Public Participation and Involvement
C) Illicit Discharge Detection and Elimination
D) Construction Site Storm Water Runoff Control Measures
E) Post Construction Storm Water Management Measures
F) Pollution Prevention and Good Housekeeping Measures
Each year by March 10th the City must hold a public meeting to review the
effectiveness of the above BMP's from the previous year and discuss proposed
changes for the coming year. A summary report of the BMP's has been prepared
for review and submittal to the MPCA for 2004 to fulfill our MS4 permit requirements.
Current Circumstances
The attached draft report details the City of Prior Lake SWPPP and BMP's
completed in 2004. City Staff will review this report for the public at the March 7th
City Council Meeting.
Conclusion
The Council should open the public hearing, receive public input and then close the
public hearing. Council should direct staff to make changes to the existing BMP's
or modifications to the SWPPP if appropriate or warranted.

those pipes that are 24 inches in diameter and over;
4) Outfalls, including discharges from your system to other MS4s, or waters
and wetlands that are not part of your system (where you do not have
operational control); structures that discharge stormwater directly into
groundwater; overland discharge points and all other points of discharge
from your system that are outlets, not diffuse flow areas.
The City has completed a map of all storm water facilities. This map
is being updated to include all construction and redevelopment
projects in 2004.

flows (i.e., illicit discharges), only if you identify them as significant
contributors of pollutants to your small MS4:

35.2005(20)), uncontaminated pumped ground water, discharges from potable
water sources, foundation drains, air conditioning condensation, irrigation
water, springs, water from crawl space pumps, footing drains, lawn watering,

4. Construction Site Stormwater Runoff Control
You must develop, implement, and enforce a program to reduce pollutants in any
stormwater runoff to your small MS4 from construction activities within your jurisdiction
that result in a land disturbance of greater than or equal to one acre or is less than one acre
but is part of a common plan of development that will be one acre or greater. You must
also select and implement a program of appropriate BMPs and measurable goals for this
minimum control measure, at minimum:
a. An ordinance or other regulatory mechanism to require erosion and sediment
controls, as well as sanctions to ensure compliance, to the extent allowable
under law. These ordinances or regulatory mechanisms must be in place by
March 11, 2005;
The City requires permits for all soil disturbing activities exceeding 10 cy
in the shoreland district and 50 cy in area outside that district. These
permits are reviewed by qualified construction site erosion control
technicians for compliance with the City's SWPPP. Additionally all
permits are inspected to ensure compliance. All development sites are
required to have a SWPPP prior to construction. City Development
contracts detail enforcement measures and requirements for all site
developments. The City enforces all soil disturbance activities in
accordance with the approved SWPPP.
Currently the City has Grading and Filling and Storm Water Ordinances
in place that deal with erosion control requirements not covered by
permitting or development contracts.
b. Requirements for construction site operators to implement appropriate erosion
and sediment control best management practices;
In place as discussed above.
c. Requirements for construction site operators to control waste, such as discarded
building materials, concrete truck washout, chemicals, litter, and sanitary waste
at the construction site that may cause adverse impacts to water quality;
Addressed in development contracts for larger projects and is handled on a
case-by-case basis by Building Inspection Department for smaller sites.
d. Procedures for site plan review which incorporate consideration of potential
water quality impacts;
The City review process requires a detailed water resource review (by a
qualified professional engineer) that meets City of Prior Lake SWPPP and
Prior Lake Spring Lake Watershed requirements. The City is currently
updating our rules to meet Scott WMO requirements and future Non-
degradation standards.
e. Procedures for receipt and consideration of reports of non compliance or other
4
3/2/2005
information on construction related issues submitted by the public, and
The City employs a full time technician who responds to all erosion and
storm water non-compliance complaints on a same day basis.
f. Procedures for site inspection and enforcement of control measures.
The City has a variety of enforcement tools. For single residences that
have not obtained permits a stop work order and restoration order can be
issued. Any non-compliance issues that are not resolved immediately or in
a timely manner are turned over to the City Attorney for legal
enforcement. Failure to resolve issues.
For projects requiring a building permit the City issues a stop work order
followed by prosecution for failure to comply.
For development or grading projects the City requires a Letter of Credit
with sufficient funds to restore any disturbed areas. If a restoration order
is ignored the City will draw on the LOC and fix the problem.
The City also works closely with DNR Enforcement Officers when impacts
to protected waters or wetlands are detected.
5. Post-construction Stormwater Mana ement in New Develo ment and Redevelo ment
You must develop, implement, and enforce a program to address stormwater runoff from
new development and redevelopment projects within your jurisdiction that disturb greater
than or equal to one acre, including projects less than one acre that are part of a larger
common plan of development or sale that discharge into your small MS4. Your program
must ensure that controls are in place that would prevent or reduce water quality impacts.
You must also select and implement a program of appropriate BMPs and measurable
goals for this minimum control measure. At minimum:
a. Develop and implement strategies which include a combination of structural
and/or non-structural best management practices (BMPs) appropriate for your
community;
b. Use an ordinance or other regulatory mechanism to address post-construction
runoff from new development and redevelopment projects to the extent
allowable under law; and
c. Ensure adequate long-term operation and maintenance of BMPs installed as a
result of these requirements.
All new development or redevelopment projects over 1 acre are required to
have an individual SWPPP. City and Watershed staff review the SWPPP's
for compliance with existing ordinances and the City SWPPP. The City is
currentl reworkin our Develo ment Contract to re uire uicker
5
3/2/2005
responses by developers and builders to BMP maintenance and storm
water and site erosion issues. The goal of our contract revisions is to have
legal standing in requiring the developer to be responsible for a
development area from initial impact to final home site restoration.
6. Pollution Prevention/Good Housekeepine for Municipal Operations
a. You must develop and implement an operation and maintenance program that
includes a training component and has the ultimate goal of preventing or
reducing pollutant runoff from municipal operations. Training materials that
are available from the USEP A, state and regional agencies, or other
organizations may be used as appropriate or modified for your community.
Your program must include employee training to prevent and reduce
stormwater pollution from activities such as park and open space maintenance,
fleet and building maintenance, new construction and land disturbances, and
stormwater system maintenance.
All municipal reconstruction projects included a SWPPP. Project
inspection was completed by City technicians who have valid certifications
in construction site management and erosion control.

training of employees working on maintained activities. The City will
continue to provide training to the individuals performing maintenance
responsibilities.
