Construction-Site Erosion Control and Stormwater Management Issues Clarified
Since March 1, 2003, federal law has required that landowners of construction sites with one-acre or more of land disturbance obtain construction site storm water permit coverage to address erosion control and storm water management.
The Notice of Intent (NOI) is the document that must be filed to assure that construction site stormwater permit coverage is obtained. The Wisconsin Department of Commerce (Commerce) has authority and the responsibility for construction site erosion control for building sites for public buildings and places or employment and one- and two-family dwellings. All commercial building construction sites disturbing one- acre or more need to submit an NOI to Commerce. The NOI form is available at: http://commerce.wi.gov/SB/SB-DivForms.html#commercial.
The Department of Natural Resources (DNR) has authority over other construction sites. It is possible that a construction site may need to submit an NOI to DNR for the initial grading and filling and then to Commerce for the soil disturbance related to the building phase of the project.
Who must submit the NOI and what work is associated with the NOI?
What is required for one- and two-family dwelling sites?
In the future, when the UDC code is revised to meet or exceed the standards in NR 151, the submittal will be to Commerce.
The Department of Commerce is an equal opportunity service provider and employer. If you need assistance to access services or need material in an alternate format, please contact the Department at (608) 266-3151 or TTY (608) 264-8777. SBD-10814 (N.6/05)
What is contained in an erosion control and stormwater management plan?
Because every site is unique, erosion control and stormwater management plans must be customized for the site. The erosion control and stormwater management plans must be designed to meet the construction and post construction standards found in NR 151, Wis. Adm.Code (See http://dnr.wi.gov/org/water/wm/nps/admrules.htm). There is a list of erosion control and stormwater management technical standards at: http://dnr.wi.gov/org/water/wm/nps/stormwater/techstds.htm.
The plans are not required to be submitted to Commerce; however the plans must be available on-site for review during an inspection. If the plan includes plumbing solutions, the plumbing plan submittal requirements are located in s. Comm 82.20.
Are there any other forms that must be submitted to Commerce?
The Notice of Termination form is available at: http://commerce.wi.gov/SB/SB-DivForms.html#commercial.
Who may I contact for more information?
Why are these requirements necessary?
Most storm sewer systems do not provide significant treatment of the stormwater discharges they receive. Sediment can cloud water and make it difficult or impossible for aquatic plants to receive the sunlight they need to grow. Excess sediment also smothers aquatic habitat, clogs fish gills, and impedes navigation in our waterways, which can lead to expensive dredging.
Every Wisconsin citizen is responsible to help keep the environment available for life. DNR has determined these measures are necessary to sustain development and protect Wisconsin's ecosystems.
