  • NR 712
    See Wis. Adm. Code ch. NR 712 for consultant signature and certification requirements.
  • NR 716

Fees and request for DNR review

Submittal of a Site Investigation Report is required within 60 days of completion of the field investigation and receipt of laboratory data, per Wis. Adm. Code s. NR 716.15.

To submit a Site Investigation Report for DNR review and response, provide the report with the applicable fee using Technical Assistance, Environmental Liability Clarification or Post-Closure Modification Request (Form 4400-237) [PDF]. Follow the instructions within the form.

Submittal of the Site Investigation Report for review and response is highly recommended, to help avoid delays during a subsequent closure review if the investigation is found to be incomplete.

Submittal requirements

Wis. Adm. Code s. NR 700.11 (3g) requires the submittal of both a paper and electronic copy of all reports. For requirements and guidance on submitting the Site Investigation Work Plan and Report to the DNR, see Guidance for Submitting Documents (RR-690) [PDF]. See Wis. Admin. Code ch. NR 712 Qualifications and Certifications (RR-081) [PDF] on the required certification per type of NR 700 report.

See Wis. Admin. Code ch. NR 712 Qualifications and Certifications (RR-081) [PDF] on the required certification per type of NR 700 report.

Site investigation checklist

The Site Investigation Report Preparation Checklist - Wis. Admin. Code s. NR 716.15 (Form 4400-317) [PDF] can be used as a tool to ensure all Wis. Admin. Code ch. NR 716 requirements for a complete site investigation are addressed. This checklist also provides a suggested format for site investigation reports and shows the relationship between each section of the site investigation report and the Case Closure Request (Form 4400-202) [PDF].
