[HISTORY: Adopted by the Town Board of the Town of Greenville 5-12-2008. Amendments noted where applicable.]
This chapter is adopted under the authority granted by § 60.627, Wis. Stats. This chapter supersedes all provisions of an ordinance previously enacted under § 60.62, Wis. Stats., that relate to construction site erosion control. Except as otherwise specified in § 60.627 Wis. Stats., § 60.62, Wis. Stats., applies to this chapter and to any amendments to this chapter.
The provisions of this chapter are deemed not to limit any other lawful regulatory powers of the same governing body.
The Town Board hereby designates the Public Works Department to administer and enforce the provisions of this chapter.
The requirements of this chapter do not preempt more stringent erosion and sediment control requirements that may be imposed by any of the following:
Wisconsin Department of Natural Resources administrative rules, permits or approvals including those authorized under §§ 281.16 and 283.33, Wis. Stats.
Targeted nonagricultural performance standards promulgated in rules by the Wisconsin Department of Natural Resources under § NR 151.004, Wis. Adm. Code.
The Town Board finds that runoff from land-disturbing construction activity carries a significant amount of sediment and other pollutants to the waters of the state in the Town of Greenville.
It is the purpose of this chapter to further the maintenance of safe and healthful conditions; prevent and control water pollution; prevent and control soil erosion; protect spawning grounds, fish and aquatic life; control building sites, placement of structures and land uses; preserve ground cover and scenic beauty; and promote sound economic growth, by minimizing the amount of sediment and other pollutants carried by runoff or discharged from land-disturbing construction activity to waters of the state in the Town of Greenville.
This chapter applies to the following land-disturbing construction activities, except as provided under Subsection A(2):
A construction site, which has 4,000 square feet or greater of land-disturbing construction activity.
A construction site, which has 100 cubic yards or greater of excavation volume, filling volume, or some combination of excavation and filling volume.
A construction site, which has 100 linear feet or greater of land disturbance to a highway, street, driveway, swale, ditch, waters of the state, wetland, protective area, or other nonagricultural drainage facility which conveys concentrated flow. Wetlands shall be delineated in accordance with § NR 103.08(1m).
This chapter does not apply to the following:
Land-disturbing construction activity that includes the construction of one- and two-family residential dwellings that are not part of a larger common plan of development or sale and that result in less than one acre of disturbance. These construction sites are regulated by the Wisconsin Department of Safety and Professional Services under § SPS 321.125, Wis. Adm. Code.
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 Chapter 40, Code of Federal Regulations, Part 122, for land-disturbing construction activity.
Nonpoint discharges from agricultural activity areas.
Nonpoint discharges from silviculture activities.
Mill and crush operations.
Notwithstanding the applicability requirements in Subsection A(1), this chapter applies to construction sites of any size that, in the opinion of the Public Works Department, 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, that increases water pollution by scouring or the transportation of particulate matter or that endangers property or public safety.
Jurisdiction. This chapter applies to land-disturbing construction activity on construction sites located within the boundaries and jurisdiction of the Town of Greenville.

Technical standards and other guidance identified within the Town of Greenville Stormwater Reference Guide.
For this chapter, average annual basis is calculated using the appropriate annual rainfall or runoff factor, also referred to as the R factor, or an equivalent design storm using a type II distribution, with consideration given to the geographic location of the site and the period of disturbance.
Responsible party. The responsible party shall implement an erosion and sediment control plan, developed in accordance with § 117-9 that incorporates the requirements of this section.
Plan. A written erosion and sediment control plan shall be developed in accordance with § 117-9 and implemented for each construction site.
Requirements. The erosion and sediment control plan shall meet the following minimum requirements to the maximum extent practicable:
BMPs shall be designed, installed and maintained to control total suspended solids carried in runoff from the construction site as follows.
For construction sites with one acre or greater of land-disturbing construction activity, reduce the total suspended solids load by 80%, on an average annual basis, as compared with no sediment or erosion controls until the construction site has undergone final stabilization. No person shall be required to exceed an 80% sediment reduction to meet the requirements of this subsection. Erosion and sediment control BMPs may be used alone or in combination to meet the requirements of this subsection. Credit toward meeting the sediment reduction shall be given for limiting the duration or area, or both, of land-disturbing construction activity, or other appropriate mechanism.
For construction sites with less than one acre of land-disturbing construction activity, reduce the total suspended solids load using BMPs from the Town of Greenville Stormwater Reference Guide. These sites are not required to satisfy a numeric performance standard.
Notwithstanding Subsection C(1), if BMPs cannot be designed and implemented to reduce the sediment load by 80%, on an average annual basis, the plan shall include a written and site-specific explanation as to why the 80% reduction goal is not attainable and the sediment load shall be reduced to the maximum extent practicable.
Where appropriate, the plan shall include sediment controls to do all of the following to the maximum extent practicable:
The use, storage and disposal of building materials, chemicals, cement, concrete truck washout, litter, sanitary waste, and other compounds and materials used on the construction site shall be managed during the construction period, to prevent their entrance into storm sewers and waters of the state. 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 subsection.
Location. The BMPs used to comply with this section shall be located prior to runoff entering waters of the state.
Alternate requirements. The Public Works Department may establish requirements more stringent than those set forth in this section if the Public Works Department determines that an added level of protection is needed for sensitive resources.
Permit required. No responsible party may commence a land-disturbing construction activity subject to this chapter without receiving prior approval of an erosion and sediment control plan for the site and a permit from the Public Works Department.
Permit application and fees. At least one responsible party desiring to undertake a land-disturbing construction activity subject to this chapter shall submit an application for a permit and an erosion and sediment control plan that meets the requirements of § 117-9 and shall pay fees identified in § 117-10 to the Public Works Department. By submitting an application, the applicant is authorizing the Public Works Department to enter the site to obtain information required for the review of the erosion and sediment control plan.
Review and approval of permit application. The Public Works Department shall review any permit application that is submitted with an erosion and sediment control plan, and the required fee. The following approval procedure shall be used:
Within 20 business days of the receipt of a complete permit application, as required by Subsection B, the Public Works Department shall inform the applicant whether the application and plan are approved or disapproved based on the requirements of this chapter.

Further, it shall also include the best management practices that will be used to meet the requirements of the ordinance, including the site development schedule.
Amendments. The applicant shall amend the plan if any of the following occur:
There is a change in design, construction, operation or maintenance at the site which has the reasonable potential for the discharge of pollutants to waters of the state and which has not otherwise been addressed in the plan.
The actions required by the plan fail to reduce the impacts of pollutants carried by construction site runoff.
The Public Works Department notifies the applicant of changes needed in the plan.
Alternate requirements. The Public Works Department may prescribe requirements less stringent for applicants seeking a permit for a construction site with less than one acre of disturbance.
The fees referred to in other sections of this chapter shall be established by the Town Board and may from time to time be modified by resolution. A schedule of the fees established by the Town Board shall be available for review in the Town Hall.
If land-disturbing construction activities are being carried out without a permit required by this chapter, the Public Works Department may enter the land pursuant to the provisions of § 66.0119(1), (2), and (3), Wis. Stats.
The Public Works Department may post a stop-work order if any of the following occurs:
If the responsible party does not cease activity as required in a stop-work order posted under this section or fails to comply with the erosion and sediment control plan or permit conditions, the Public Works Department may revoke the permit.
If the responsible party, where no permit has been issued, does not cease the activity after being notified by the Public Works Department, or if a responsible party violates a stop-work order posted under Subsection A, the Public Works Department may request the Town Attorney to obtain a cease-and-desist order in any court with jurisdiction.
After posting a stop-work order under Subsection A, the Public Works Department may issue a notice of intent to the responsible party of its intent to perform work necessary to comply with this chapter. The Public Works Department may go on the land and commence the work after issuing the notice of intent. The costs of the work performed under this subsection by the Public Works Department, plus interest at the rate authorized by the Town Board, shall be billed to the responsible party or recovered from the surety bond, cash escrow, or irrevocable letter of credit. In the event a responsible party fails to pay the amount due, the Clerk shall enter the amount due on the tax rolls and collect as a special assessment against the property pursuant to Subch. VII of Ch. 66, Wis. Stats.
The forfeiture amount of a violation, upon conviction, shall be as set from time to time by ordinance in the Fine and Forfeiture Schedule of the Town of Greenville. Each calendar day a violation exists shall constitute a separate offense.
Compliance with the provisions of this chapter may also be enforced by injunction in any court with jurisdiction. It shall not be necessary to prosecute for forfeiture or a cease-and-desist order before resorting to injunctional proceedings.
