30-10
OFFSITE STORMWATER TREATMENT REQUIREMENTS
THE CITY COUNCIL OF THE CITY OF SPRING PARK, MINNESOTA ORDAINS AS
FOLLOWS:
Section 30-10- Offsite Stormwater Treatment Requirements.
This section is adopted pursuant to Minn. R. 7090 to ensure compliance with the Minnesota Municipal Separate
Storm Sewer System (MS4) General Permit.The city council finds that when onsite stormwater treatment is not
feasible, offsite treatment must be implemented to prevent negative impacts on receiving waters and maintain
compliance with water quality standards.
(a) Requirement for Offsite Treatment
When stormwater treatment cannot be fully achieved onsite for a construction project within the city,the
permittee shall ensure that an equivalent volume of stormwater treatment is provided offsite. Offsite treatment
project areas shall be selected in the following order of preference:
1. Locations that yield benefits to the same receiving water that receives runoff from the original
construction activity.
2. Locations within the same Minnesota Department of Natural Resources (DNR) catchment area as the
original construction activity.
3. Locations in the next adjacent DNR catchment area upstream of the original construction activity.
4. Locations anywhere within the jurisdictional boundaries of the permittee.
(b) Stormwater Treatment Standards
Offsite treatment projects must involve the creation of new structural stormwater BMPs,the retrofit of existing
structural stormwater BMPs, or the use of a properly designed regional structural stormwater BMP. Routine
maintenance of existing structural stormwater BMPs required by the General Permit cannot be used to meet this
requirement.
(c) Project Completion Timeline
All offsite treatment projects must be completed no later than 24 months after the start of the original construction
activity. If additional time is required, the permittee must provide justification and an updated schedule for project
completion in the annual report.
(d) Use of Payments for Offsite Treatment
If the permittee receives payment from the owner of a construction activity for offsite treatment,the permittee
must apply the payment to a public stormwater project that meets the requirements outlined in this section.
(e) Compliance and Enforcement
The Spring Park Stormwater Management personnel shall oversee compliance with these requirements through
project review,inspections, and enforcement actions as necessary. Projects that fail to comply with this section shall
be subject to enforcement measures,including fines,stop-work orders, or other corrective actions as determined by
the city.
Effective Date. This ordinance shall be in full force and effective immediately upon its passage and
publication.
