The extent to which existing best management practices have proven to be effective in addressing the pollutant of concern covered by the wasteload allocation. NR 216.07(10)(c)5.5. Whether the TMDL implementation plan is appropriate and necessary because the permittee cannot attain the wasteload load allocations within the existing permit term. NR 216.07(10)(d)(d) Assessment. A permittee shall conduct an assessment of the actions required to be taken under this subsection. The assessment shall include a pollutant-loading analysis using an urban water quality model that uses small storm hydrology or equivalent methodology that is approved by the department, or monitoring, trend analysis, or other appropriate qualitative or quantitative evaluation methods approved by the department. At a minimum, a pollutant-loading analysis shall be conducted for total suspended solids, phosphorus, any applicable pollutants of concern covered under an applicable US EPA-approved TMDL, and pollutants of concern discharged by the permittee to a listed impaired waterbody, ERW, or ORW. NR 216.07 NoteNote: The department believes that computer modeling provides an efficient and cost-effective method for calculating pollutant loads. Pollutant loading models such as WinSLAMM, P8, or equivalent methodology may be used to evaluate the efficiency of the design in reducing total suspended solids.

NR 216.075(2)(2) A permittee may rely on another entity to implement a minimum control measure or another requirement of a permit issued under this subchapter provided all the following conditions are met: NR 216.075(2)(a)(a) The other entity implements the minimum control measure or permit requirement. NR 216.075(2)(b)(b) The minimum control measure or requirement, or component thereof, is at least as stringent as the corresponding permit requirement. NR 216.075(2)(c)(c) The other entity agrees to implement a minimum control measure or requirement on the permittee’s behalf, demonstrated by executing a formal written agreement signed by both parties’ authorized representatives. The agreement shall be explicit as to which specific minimum control measure or requirement is being implemented by the other entity.

(2), or does not meet a requirement of a permit issued under this subchapter, the permittee may not rely on the other entity to implement the minimum control measure or requirement. NR 216.075(4)(4) If the department finds that the other entity does not effectively implement a minimum control measure or requirement pursuant to an agreement executed under this section, the permittee shall not rely on the other entity to implement the minimum control measure or requirement. NR 216.075(5)(5) A permittee or other entity that terminates an agreement under this section shall notify the department within 5 business days of the termination. Upon termination, the permittee shall become responsible for implementing a minimum control measure or other requirement of a permit issued under this subchapter that was subject to an agreement under sub.

For town owned or operated municipal separate storm sewer systems, an annual permit fee shall be based on the population within the urbanized area as defined by the U.S. census bureau. The annual permit fees are listed in Table 1. NR 216.08(2)(2) For any other owner or operator of a municipal separate storm sewer system including county, state and federal systems, the fee shall be $500. NR 216.08 NoteNote: The annual permit fee is the same regardless of whether the municipal separate storm sewer system is covered under a general permit or an individual permit alone or with co-permittees. Municipal permit fees were established in order to administer the municipal permit program pursuant to s. 283.33 (9) (b), Stats. NR 216.08 HistoryHistory: CR 03-028: cr.
