Chapter NR 216

NR 216.47(6) (6) Management practices. Best management practices to control impacts from storm water runoff include infiltration systems, wet detention ponds, constructed wetlands, grassed swales, vegetative protective areas, reduced imperviousness, beneficial reuse such as irrigation or toilet flushing, combinations of these practices, or other methods which do not cause significant adverse impact on the receiving surface water or groundwater. The plan shall include an explanation of the technical basis used to select the best management practices.

NR 216.47 Note Note: Pursuant to s. NR 151.32 (2), the department maintains a list of technical standards that it has determined adequate and effective for designing best management practices to control storm water runoff. Contact the department storm water program in the Bureau of Watershed Management at [phone] to obtain a copy of this list.

NR 216.46 and the storm water management plan required under s. NR 216.47 shall contain a written assessment of the potential for storm water from the facility to discharge a pollutant of concern and identify the control measures and maintenance practices that will collectively be used to reduce, with the goal of eliminating, storm water discharge containing pollutants of concern.

NR 216.49(4) (4) TMDL. If the permittee is subject to an US EPA-approved TMDL, the erosion control plan required under s. NR 216.46 and the storm water management plan required under s.

NR 216.50(1) (1) Landowner initiated. The permittee or landowner required to submit a notice of intent under this subchapter shall amend the erosion control and storm water management plans if either of the following occurs:

NR 216.50(1)(a) (a) There is a change in design, construction, operation or maintenance at the construction site which has the reasonable potential for the discharge of pollutants and which has not otherwise been addressed in the erosion control and storm water management plans. Changes that may trigger an amendment include addition of access points, additional land disturbing construction activity not included in the original plan, a change or elimination of a best management practice, an increase in proposed impervious area, and changes to post-construction site treatment practices. The department may require a permittee to file a new notice of intent if the amended site requires resource screening of additional area or the amended site no longer meets an exemption from post-construction performance standards under ss. NR 151.121 to 151.125.

NR 216.50(1)(b) (b) The actions required by the plan fail to reduce the impacts of pollutants carried by storm water runoff.

NR 216.50(2) (2) Submittal requirements. For construction sites for which there has been earlier department review of the erosion control and storm water management plans, if the permittee or landowner required to submit a notice of intent under this subchapter identifies changes needed in either plan, the permittee or the landowner required to submit a notice of intent under this subchapter shall notify the department 5 working days prior to making the changes in the plan.

NR 216.50(3) (3) Permit modification. The department may, upon request of a permittee or upon finding of just cause, modify the compliance and reporting schedules or any requirement of a storm water discharge permit.

NR 216.51(1) (1) Inadequate plans. The department may notify the permittee or landowner required to submit a notice of intent under this subchapter at any time that the erosion control or storm water management plans do not meet one or more of the requirements of this subchapter, or a permit issued pursuant to this subchapter, for reducing and preventing the discharge of pollutants. The notification shall identify those provisions that are not being met by the erosion control or storm water management plan, and identify which provisions of the plan require modifications in order to meet the requirements.

NR 216.51(2) (2) Required plan revisions. Within the time frame identified by the department in its notification, the permittee or landowner required to submit a notice of intent under this subchapter shall make the required changes to the erosion control and storm water management plans, perform all actions required by the revised plans, and submit to the department a written certification that the requested changes have been made and implemented, and submit other information the department requires. The department may revoke construction site storm water discharge permit coverage for failure to comply with this section or take action under s. 283.89, Stats. The landowner of a construction site where the department has revoked coverage under the general WPDES permit may not discharge storm water to waters of the state from the construction site unless an individual WPDES permit for storm water discharge is issued to the landowner.

NR 216.51(3) (3) Other storm water discharges. The department may require the landowner of any storm water discharge associated with land disturbing construction activity to apply for and obtain a storm water discharge permit if the storm water discharge is either:

NR 216.51(3)(a) (a) Contributing to the violation of a water quality standard, or

NR 216.51(3)(b) (b) Contributing significant pollution to waters of the state.

NR 216.51 Note Note: This subsection allows the department to require permit coverage of construction sites with less than one acre of land disturbance.

NR 216.51(4) (4) Denial or revocation of general permit. The department may deny or revoke coverage under a general WPDES permit and require submittal of an application for an individual WPDES storm water permit based on a review of the completed notice of intent or other relevant information. The landowner of a construction site denied or revoked coverage under the general WPDES permit may not discharge storm water to waters of the state from the construction site until an individual WPDES permit for storm water discharge is issued to the landowner.

NR 216.51(5) (5) Individual permit. The department may require the landowner of any storm water discharge covered by a general WPDES permit issued pursuant to this subchapter to apply for and obtain an individual WPDES storm water permit if any of the following occur:

NR 216.51(5)(a) (a) The storm water discharge is determined to be a significant source of pollution and more appropriately regulated by an individual WPDES storm water permit.

NR 216.51(5)(b) (b) The storm water discharge is not in compliance with the terms and conditions of this subchapter, or of a general WPDES permit issued pursuant to this chapter.

NR 216.54 NR 216.54 Transfers. A landowner who has submitted a completed notice of intent and does not intend to control the permitted activities on the construction site may transfer authorization of construction site storm water discharge permit coverage to the person who will control the permitted activities. The transfer request shall be completed on forms provided by the department as specified under s. NR 216.006 and signed by both the current permittee and the proposed permittee. Coverage is not transferred until the department sends notification of transfer approval to the new permittee. The department may require additional information to be filed prior to granting coverage under the general WPDES permit.

NR 216.55(1) (1) When to file. When a construction site has undergone final stabilization, temporary erosion control best management practices have been removed and all storm water discharges associated with the construction site activities that were required to have WPDES permit coverage under this subchapter have ceased, the permittee shall submit a signed notice of termination to the department.

NR 216.55(2) (2) Forms. A notice of termination shall be submitted to the department on forms available from the department as specified under s. NR 216.006. Data submitted in the notice of termination forms shall be used as a basis for terminating coverage of a storm water discharge permit.

I understand that by submitting this notice of termination, I am no longer authorized to discharge storm water associated with construction activity by the general WPDES permit, and that discharging pollutants in storm water associated with construction activity to waters of Wisconsin is unlawful where the discharge is not authorized by a general WPDES permit.”

NR 216.55(5) (5) Effective date. Termination of coverage under the permit shall be effective upon written confirmation of permit termination by the department to the permittee.

NR 216.55(6) (6) Administrative termination. If an applicant fails to reapply under s. NR 216.43 (5) or submit a notice of termination under this section, the department may administratively terminate permit coverage 3 years after the date the department conveyed coverage.
