292.31(2)(2) Environmental response rules.

292.31(3)(c)(c) Sequence of remedial action. In determining the sequence for taking remedial action under this subsection, the department shall consider the significance to public health, the community, and the environment of each site or facility, the amount of funds available, the information available about each site or facility, the willingness and ability of an owner, operator, or other responsible person to undertake or assist in remedial action, the availability of federal funds under 42 USC 9601, et seq., and other relevant factors. The department shall give the highest priority to remedial action at sites or facilities which have caused contamination of a municipal water system.

292.31(3)(d)(d) Emergency responses. Notwithstanding rules promulgated under this section or the considerations for taking action under par. (c), the department may take emergency action under this subsection and subs. (1) and (7) at a site or facility if delay will result in imminent risk to public health or safety or the environment. The department is not required to hold a hearing under par. (f) if emergency action is taken under this paragraph. The decision of the department to take emergency action is a final decision of the agency subject to judicial review under ch. 227.

292.31(3)(e)(e) Access to property. Any officer, employee or authorized representative of the department may enter onto any site or facility and areas surrounding the site or facility at reasonable times and upon notice to the owner or occupant to take action under this section. Notice to the owner or occupant is not required if the delay required to provide this notice is likely to result in an imminent risk to public health or welfare or the environment.

292.31(3)(f)(f) Notice; hearing. The department shall publish a class 1 notice, under ch. 985, shall publish the notice on its Internet website, and, upon request, shall provide the notice to interested members of the public, prior to taking remedial action under this subsection and subs. (1) and (7). The department’s notice to interested members of the public may be given through an electronic notification system established by the department. The notice shall describe the proposed remedial action, the amount and purpose of any proposed expenditure, the name and address of the facility that is the subject of the proposed remedial action, a brief description of the proposed remedial action, and information indicating where more information regarding the proposed remedial action may be viewed on the department’s Internet website. For the purpose of determining the date on which notice is provided under this paragraph, the date on which the department first publishes the notice on its Internet website shall be considered the date of notice. Except as provided under par. (d), the department shall provide a hearing to any person who demands a hearing within 30 days after the notice is published for the purpose of determining whether the proposed remedial action and any expenditure is within the scope of this section and is reasonable in relation to the cost of obtaining similar materials and services. The department is not required to conduct more than one hearing for the remedial action proposed at a single site or facility. Notwithstanding s. 227.42, the hearing shall not be conducted as a contested case. The decision of the department to take remedial action under this section is a final decision of the agency subject to judicial review under ch. 227.

292.31(4)(4) Monitoring costs at nonapproved facilities owned or operated by municipalities. Notwithstanding the environmental response rules under sub.

The amount expended by the department under this subsection may not exceed the balance in the environmental fund that is available for environmental repair at the beginning of that fiscal year or 50 percent of the balance in the investment and local impact fund at the beginning of that fiscal year, whichever amount is greater.
