Part 7077.0119 - POINTS FOR STORM WATER PROJECTS

Subpart 1. Discharges to impaired waters.

Subp. 1a. Discharges to ORVW's or trout waters.

Subp. 2. Receiving water classification.

Up to seven points shall be assigned based on the classification of the receiving water as provided in this subpart if the storm water project provides treatment that reduces the quantity or improves the quality of storm water discharges. If the receiving water has multiple classifications, only the classification with the highest point value under this subpart shall be used.

Subp. 3. Project implements corrective measures.

Five points shall be assigned to a storm water project if it implements actions that contribute to correction of a water quality problem identified in one or more of the following studies or an equivalent study:

Subp. 4. [Repealed, 38 SR 444]

Subp. 5. New or expanded diversion of storm water; points subtracted.

Five priority points shall be subtracted from the project's priority score if the project involves a new or expanded diversion of storm water to one or more of the following types of water or to a subwatershed that flows into that water:

Subp. 6. Project helps meet total maximum daily load for receiving water.

Eighteen points shall be assigned if the municipality proposing the project holds a NPDES permit for a municipal separate storm sewer system and is implementing a storm water pollution prevention program according to Code of Federal Regulations, title 40, section 122.34, that addresses requirements resulting from a total maximum daily load waste load allocation.

Subp. 7. Impervious surface ratio.

Up to ten points shall be assigned to a storm water project that addresses impervious surfaces through BMP's. The points are determined by the number resulting from multiplying 20 times the ratio of the project service area's impervious surface area to the total project service area to be served by the proposed BMP's and rounding up numbers with fractions to the next whole number.

Subp. 8. Volume reduction.

Nine points shall be assigned if the proposed project will result in a storm water volume reduction from an existing discharge. The proposed project must incorporate volume reduction as a major component of the treatment system, or volume reduction must comprise a majority of the cost of the overall proposal. Qualifying best management practices include:

Subp. 9. New treatment systems.

Additional points shall be assigned if the proposed project includes new best management practices that provide treatment to an existing discharge, where the discharge is presently untreated. The number of points shall be awarded based on whether the applicant holds a municipal separate storm sewer system (MS4) NPDES permit that already requires a load reduction based on a total maximum daily load (TMDL):

Subp. 10. Multiple environmental benefits.

Six points shall be assigned if the proposed project will result in one or more of the multiple environmental benefits described in items A to F. Eligible projects must include a storm water treatment system component or best management practice, and another type of environmental benefit that results from the project. Flood control is already a priority goal of storm water management, so it does not constitute another type of environmental benefit. Qualifying multiple environmental benefits include:

Subp. 11. Structural improvements to existing storm water ponds.

Ten points shall be assigned to a project for structural improvements to an existing storm water pond that increase or improve storm water treatment. No points shall be assigned for projects that address only maintenance and do not propose structural improvements.
