Wisconsin Administrative Code › Department of Natural Resources › NR 200-299 - Environmental Protection - Wisconsin Pollutant Discharge Elimination System › Chapter NR 216 - Storm Water Discharge Permits › Subchapter III - Construction Site Storm Water Discharge Permits › Section NR 216.46 - Erosion control plan requirements

Current through June 24, 2024
(1) SITE-SPECIFIC
				  PLAN. The permittee or landowner required to submit a notice of intent under
				  this subchapter shall develop a site-specific erosion control plan for each
				  construction site regulated by this subchapter. The permittee or landowner
				  required to submit a notice of intent under this subchapter, or their
				  representative, shall implement and maintain as appropriate all best management
				  practices specified in the erosion control plan from the start of land
				  disturbing construction activities until final stabilization of the
				  construction site.
(2) PERFORMANCE
				  STANDARDS. The construction site erosion control plan shall meet the applicable
				  performance standards in either s.
				  NR
				  151.11 for construction sites that are not
				  transportation facilities or s.
				  NR
				  151.23 for transportation facility construction sites.
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 erosion and sediment runoff.
					 Contact the department storm water program in the Bureau of Watershed
					 Management at (608) 267-7694 to obtain a copy of this list. Transportation
					 facilities regulated under ch. Trans 401 generally have a 2-step plan
					 development process of an erosion control plan (ECP) that contains design
					 requirements and then development of an erosion control implementation plan
					 (ECIP) that includes implementation details. This subchapter requires an
					 erosion control plan that is equivalent to the ch. Trans 401 ECP and ECIP plans
					 put together.
(3) PLAN
				  COMPLETION. The erosion control plan shall be completed prior to the submittal
				  of a notice of intent to the department and shall be updated as appropriate
				  pursuant to s.
				  NR
				  216.50.
(4) REQUIRED INFORMATION. The construction
				  site erosion control plan shall include, at a minimum, the following items:
(a) Description of the construction site and
				  the nature of the land disturbing construction activity, including
				  representation of the limits of land disturbance on a USGS 7.5-minute series
				  topographical map or as specified by the department.
(b) Description of the intended sequence of
				  major land disturbing construction activities for major portions of the
				  construction site, such as grubbing, excavation or grading.
(c) Estimates of the total area of the
				  construction site and the total area of the construction site that is expected
				  to be disturbed by land disturbing construction activities.
(d) Available data describing the surface
				  soil as well as subsoils.
(e)
				  Wherever permanent infiltration devices will be employed or were evaluated, the
				  depth to the nearest seasonal high groundwater elevation or top of bedrock
				  shall be identified as outlined in s.
				  NR
				  216.47(3).
(f) Name of immediate named receiving water
				  from the United States geological service 7.5-minute series topographic
				  maps.
(g) Identify receiving
				  waters, including downstream waters, that are designated as ERW, ORW, or
				  impaired waters.

					 and exceptional resource waters may be found on the department website at:

					 impaired waterbodies is updated every two years and may be found on the
					 department website at:
