(a)
Except as provided under par. (b), this ordinance applies to any construction site as defined under S. 05 (6).
(b) This ordinance does not apply to any of the following:
1. Transportation facilities, except transportation facility construction projects that are part of a larger common plan of development such as local roads within a residential or industrial development.
Note to Users: Transportation facility projects directed and supervised by the Wisconsin Department of Transportation are not subject to this ordinance. Notwithstanding this ordinance, a municipality is required to comply with the construction site transportation facility performance standards in subch. IV of ch. NR 151, Wis. Adm. Code, for its own transportation-related projects. If a municipality has regulatory authority over the activities of another local unit of government, it may be appropriate to include the construction site transportation facility performance standards in ss. NR 151.225 (3) and 151.23 (4m), Wis. Adm. Code, in its ordinance if those types of projects occur.
2.
A construction project that is exempted by federal statutes or regulations from the requirement to have a national pollutant discharge elimination system permit issued under ch.
40, Code of Federal Regulations, part 122, for land disturbing construction activity.
3. Nonpoint discharges from agricultural facilities and practices.
4. Nonpoint discharges from silviculture activities.
5. Routine maintenance for project sites that have less than 5 acres of land disturbance if performed to maintain the original line and grade, hydraulic capacity, or original purpose of the facility.
(c) Notwithstanding the applicability requirements in par. (a), this ordinance applies to construction sites of any size that, as determined by the [administering authority], are likely to result in runoff that exceeds the safe capacity of the existing drainage facilities or receiving body of water, that causes undue channel erosion, or that increases water pollution by scouring or transporting of particulate.
Note to Users: The municipality may want to consider separate legal authority to address situations when persons other than the responsible party destroy or render ineffective Best Management Practices (BMPs) constructed to meet the performance standards of this ordinance.
(2) JURISDICTION.
This ordinance applies to [land disturbing construction activity on lands within the boundaries and jurisdiction of the [name of municipality];
or
land disturbing construction activities on lands within the boundaries and jurisdiction of the [name of municipality], as well as the extraterritorial division of land subject to an ordinance enacted pursuant to s. 236.45 (2) and (3), Wis. Stats.;
or
land disturbing construction activities on lands within the boundaries and jurisdiction of the [name of municipality], as well as all lands located within the extraterritorial plat approval jurisdiction of [name of municipality], even if plat approval is not involved].
Note to Users: These options differ in the amount of land area covered by this ordinance and may have ramifications for enforcement authority. For counties, the first option is the only option since counties do not have extraterritorial authority. Under s. 59.693 (10), Wis. Stats., if a county ordinance exists at the time of annexation, then the municipal ordinance must be at least as restrictive as the county ordinance.
(3) EXCLUSIONS.
This ordinance is not applicable to activities conducted by a state agency, as defined under s.
227.01 (1), Wis. Stats.

S. 055 APPLICABILITY OF MAXIMUM EXTENT PRACTICABLE.
Maximum extent practicable applies when a person who is subject to a performance standard of this ordinance demonstrates to the [administering authority]'s satisfaction that a performance standard is not achievable and that a lower level of performance is appropriate. In making the assertion that a performance standard is not achievable and that a level of performance different from the performance standard is the maximum extent practicable, the responsible party shall take into account the best available technology, cost effectiveness, geographic features, and other competing interests such as protection of public safety and welfare, protection of endangered and threatened resources, and preservation of historic properties.
S. 06 TECHNICAL STANDARDS.
All BMPs required for compliance with this ordinance shall meet design criteria, standards, and specifications based on any of the following:
(1)
Design guidance and technical standards identified or developed by the Wisconsin Department of Natural Resources under subch.
V of ch. NR 151, Wis. Adm. Code.
(2) Soil loss prediction tools (such as the Universal Soil Loss Equation (USLE)) when using an appropriate rainfall or runoff factor (also referred to as the R factor) or an appropriate design storm and precipitation distribution, and when considering the geographic location of the site and the period of disturbance.
Note to Users: The USLE and its successors RUSLE and RUSLE2, utilize an R factor that has been developed to estimate annual soil erosion, averaged over extended time periods. The R factor can be modified to estimate monthly and single-storm erosion.
(3) Technical standards and methods approved by the [administering authority].
Note to Users: The following section, S. 07, “Performance Standards for Construction Sites Under One Acre,” is optional.
S. 07 PERFORMANCE STANDARDS FOR CONSTRUCTION SITES UNDER ONE ACRE.
(1) RESPONSIBLE PARTY. The responsible party shall comply with this section.
(2)
EROSION AND SEDIMENT CONTROL PRACTICES. Erosion and sediment control practices at each site where land disturbing construction activity is to occur shall be used to prevent or reduce all of the following:
(a)
The deposition of soil from being tracked onto streets by vehicles.
(b) The discharge of sediment from disturbed areas into on-site storm water inlets.
(c) The discharge of sediment from disturbed areas into adjacent waters of the state.
(d) The discharge of sediment from drainage ways that flow off the site.

(f) The discharge of sediment eroding from soil stockpiles existing for more than 7 days.
(g) The transport by runoff into waters of the state of chemicals, cement, and other building compounds and materials on the construction site during the construction period. However, projects that require the placement of these materials in waters of the state, such as constructing bridge footings or BMP installations, are not prohibited by this subdivision.
(3) LOCATION. The BMPs shall be located so that treatment occurs before runoff enters waters of the state.
(4) IMPLEMENTATION. The BMPs used to comply with this section shall be implemented as follows:
(a)
Erosion and sediment control practices shall be constructed or installed before land disturbing construction activities begin.
(b) Erosion and sediment control practices shall be maintained until final stabilization.
(c) Final stabilization activity shall commence when land disturbing activities cease and final grade has been reached on any portion of the site.
(d) Temporary stabilization activity shall commence when land disturbing activities have temporarily ceased and will not resume for a period exceeding 14 calendar days.
(e) BMPs that are no longer necessary for erosion and sediment control shall be removed by the responsible party.
