Section 291.37 - Corrective action(1) DEFINITIONS. In this section: (a) "Corrective action" means any method for protecting human health or the environment from a release.(b) "Release" means any spill, leak, pumping, pouring, emission, emptying, discharge, injection, escape, leaching, dumping or disposal of a hazardous waste or hazardous constituent.(c) "Solid waste management unit" means any unit designed or used for the storage, treatment or disposal of solid waste or hazardous waste or both, which is located in a hazardous waste facility required to have a license under s. 291.25 or a permit under 42 USC 6925 or required to comply with s. 291.29 . "Solid waste management unit" includes but is not limited to a container, tank, surface impoundment, disposal facility, incinerator, wastepile, landfill, underground injection well, land treatment unit or wastewater treatment facility.(d) "Surface impoundment" means all or any part of a hazardous waste facility that is a natural topographic depression, constructed excavation or diked area, that is formed primarily of earthen materials and that holds or is designed to hold liquid waste or waste containing liquids that are readily separable from the solid waste portion of the waste. "Surface impoundment" includes a pond, lagoon or holding, storage, settling or aeration pit, but does not include an underground injection well or a topographic depression containing surface water, such as a drainage ditch containing runoff from a parking lot or a storm water retention basin, unless the surface water is contaminated by a hazardous waste.(2) CORRECTIVE ACTION. (a) If the department determines that a release from a solid waste management unit has occurred the department may, except as provided under par. (b), require the owner or operator of the facility containing the solid waste management unit to take corrective action, including corrective action beyond the facility, if necessary. The department may require an owner or operator to take corrective action regardless of when the hazardous waste or hazardous constituent released was placed in the solid waste management unit. The department may require corrective action by means of a special order under this paragraph or as a condition of licensing or plan approval under s. 291.25 or 291.29 . An order or condition under this paragraph shall state, with reasonable specificity, the nature of the corrective action required, shall include a description of the property on which the corrective action is to be taken and shall specify a period for achieving compliance and a period for the owner or operator to establish proof of financial responsibility for the cost of corrective action.(b) If an owner or operator who is required under par. (a) to take corrective action on property that is beyond a facility shows that despite making a good faith effort the owner or operator was unable to obtain permission from the owner or occupant to enter that property, the owner or operator need not comply with the requirement with respect to that property.1987 a. 384; 1993 a. 16; 1995 a. 227 s. 696; Stats. 1995 s. 291.37.
