DNR staff have created the following example of how Recarga may be used to show compliance with infiltration and TSS standards. This example is only intended to illustrate a general application approach.
More about Recarga: This model is used for evaluating the performance of bioretention facilities, rain gardens, and infiltration basins. Individual facilities with surface ponding, up to 3 distinct soil layers, and optional underdrains can be modeled under user-specified precipitation and evaporation conditions. For more information, visit the DNR Recarga website.
Permittees (WPDES Permit No. WI-S050075-3): To access the list of affected permittees, go to dnr.wi.gov and search ‘storm water’. Directions to access the information are in the upper right corner of the page. See public notice information.
Permitted Activity: Storm water discharges to waters of the state from municipal separate storm sewer systems (MS4) that is owned, operated, and maintained by municipalities, located throughout Wisconsin.
Receiving Waters and Locations: Waters of the State of Wisconsin.
Department of Natural Resources Determination: The Department has made a preliminary determination to reissue WPDES Permit No. WI-S050075-3. Requirements and conditions to protect the waters of the state in accordance with applicable state statutes and administrative codes are included in the proposed general permit.
WEPA Compliance Determination under s. NR 150.35(2), Wis. Adm. Code: Reissuance of WPDES Permit No. WI-S050075-3 is a prior compliance action under s. NR 150.20(3)(a)8., Wis. Adm. Code.
Nature of Discharges Covered by the Permit: The proposed general permit contains the requirements set forth under ch. NR 216, Wis. Adm. Code, and the developed urban area performance standard specified in NR 151, Wis. Adm. Code. The proposed general permit applies to discharges to waters of the state throughout the state of Wisconsin.
General Permit Description (WPDES Permit No. WI-S050075-3): Currently, storm water discharges to waters of the state from 149 MS4s covered under the MS4 general permit, Permit No. WI-S050075-2 and from 27 MS4s covered under the MS4 general permit, Permit No. WI-S050181-1. Both WPDES general permits expire on April 30, 2019. The Department proposes to cover the current 176 existing MS4 permittees under Permit No. WI-S050075-3 after it is reissued. The MS4 general permit requires a regulated municipality to reduce pollutants that discharge through its MS4 to waters of the state via the development, implementation, and maintenance of programs for public education and outreach, public involvement and participation, illicit discharge detection and elimination, construction site pollutant control, post-construction pollutant control, pollution prevention at its municipal operations, and meeting the developed urban area performance standard under NR 151, Wis. Adm. Code. In addition, the general permit requires the development and updating of a storm sewer system map and an annual report to the Department. Furthermore, the proposed general permit specifies the implementation requirements to begin complying with an approved Total Maximum Daily Load, if applicable.
