Wisconsin Administrative Code › Department of Transportation › Chapter Trans 401 - Construction Site Erosion Control And Storm Water Management Procedures For Department Actions › Section Trans 401.06 - Performance standards

Current through June 24, 2024
(1) GENERAL. Best management practices shall
			 be employed to avoid or minimize soil, sediment and pollutant movement, or to
			 manage runoff, onto or off a project site or selected site, including the
			 avoidance or minimization of discharges to off-site areas, public sewer inlets
			 and waters of the state.
(2)
			 REMOVAL OF TEMPORARY BEST MANAGEMENT PRACTICES. A prime contractor or utility
			 person, as appropriate, shall remove or cause the removal of all temporary best
			 management practices at a site when permanent best management practices have
			 been installed to the satisfaction of the project engineer or inspector or when
			 the project engineer or inspector determines that temporary best management
			 practices are no longer required for the purpose intended and orders their
			 removal. The department shall remove or cause to be removed all temporary best
			 management practices at a project site or selected site when permanent best
			 management practices have been installed, if the department has accepted the
			 project as final before the temporary best management practices are
			 removed.
(3) TRACKING. Soils
			 tracked by construction or maintenance equipment from a project site or
			 selected site onto a public or private paved roadway or sidewalk shall be
			 minimized to the maximum extent practicable. The contractor or utility person
			 shall clean or remove soils tracked onto a public or private paved roadway or
			 sidewalk in a manner consistent with this chapter within the period specified
			 by the project engineer or, if no period is specified, within 24 hours after
			 the occurrence, to prevent sedimentation of the tracked soils into waters of
			 the state.
(4) SEDIMENT CLEANUP AND
			 REMOVAL. The contractor shall clean up or remove sediment discharged as a
			 result of a storm event in a manner consistent with this chapter and in a
			 timely fashion as conditions allow at the direction of the project engineer.
			 The utility person shall clean up or remove sediment discharged because of a
			 storm event in a manner consistent with this chapter and in a timely fashion as
			 conditions allow at the direction of the department's authorized
			 representative. The contractor or utility person shall clean up or remove other
			 off-site sediment discharged by construction or maintenance activity at the end
			 of each work day. Costs incurred under this subsection because of a storm event
			 shall be borne as provided in s.
			 Trans
			 401.12.
(5) PUBLIC SEWER INLET PROTECTION. The
			 contractor or utility person, in accordance with best management practices,
			 shall protect downslope, off-site public sewer inlets reasonably subject to a
			 discharge and downslope, on-site public sewer inlets.
(6) BUILDING MATERIAL AND OTHER WASTE
			 DISPOSAL. The contractor or utility person shall properly manage and dispose of
			 building materials and other wastes to prevent pollutants and debris from being
			 carried off site by wind or runoff. No person may permit the discharge of any
			 solid materials, including building materials, in violation of chs. 30 and 31,
			 Stats., or section 404 permit requirements. The contractor or utility person
			 shall dispose of building material and other solid wastes, including surplus
			 materials from a project and materials not suitable for use on a project, in
			 accordance with all applicable federal, state and local laws, regulations,
			 rules and ordinances relating to the disposal of solid wastes.
Note: Contact the local fire department for directions on
				proper disposal of flammable, combustible, toxic materials and other hazardous
				substances.
(7) GROUNDWATER
			 LIMITATIONS. When permanent infiltration systems are used, the department shall
			 conduct appropriate on-site testing to determine if the seasonal high
			 groundwater elevation or top of bedrock is within 5 feet of the bottom of the
			 proposed infiltration system. If permanent infiltration systems are to be used
			 and there is a well serving a community water system within 400 feet or a well
			 serving a non-community or private water system within 100 feet, the
			 groundwater flow must be identified in accordance with the provisions specified
			 in either ch. NR 110 or 214.
(8)
			 DISCHARGE VELOCITY; SITE DEWATERING.
(a) The
			 contractor or utility person shall place velocity dissipation devices at
			 discharge locations and along the length of any outfall channel as necessary to
			 provide a non-erosive flow from a structure to a water course that maintains
			 and protects the natural physical and biological characteristics and functions
			 of the water course.
(b)
1. In this paragraph, "karst feature" means
			 an area or surficial geologic feature subject to bedrock dissolution so that it
			 is likely to provide a conduit to groundwater, and may include caves, enlarged
			 fractures, mine features, exposed bedrock surfaces, sinkholes, springs, seeps
			 or swallets.
2. No contractor or
			 utility person may knowingly direct site dewatering effluent into surface
			 waters of the state or to a karst feature, unless the sediment in the effluent
			 has been reduced to the maximum extent practicable and the discharge does not
			 create an erosion problem downstream prior to entering a surface water of the
			 state or a karst feature, or unless the department of natural resources has
			 approved the action.
