DHS 157.15(5)(c)2.2. Waste inventory increasing above the amount estimated.
DHS 157.15(5)(c)3.3. Waste disposal costs increasing above the amount previously estimated.

DHS 157.15(5)(c)8.8. Use of a settling pond.
DHS 157.15(6)(6)Financial assurance options. A licensee may use any of the following methods to provide financial assurance for decommissioning:
DHS 157.15(6)(a)(a) Prepayment. Prepayment is the deposit prior to operation into an account segregated from licensee assets and outside the licensee’s administrative control of cash or liquid assets in an amount sufficient to pay decommissioning costs. Prepayment may be in the form of a trust, escrow account, government fund, certificate of deposit or deposit of government securities.
DHS 157.15(6)(b)(b) Surety method, insurance or other guarantee. Payment of future decommissioning costs shall be guaranteed by a surety method, insurance or other guarantee. A surety method may be in the form of a surety bond, letter of credit or line of credit. Self insurance, or any method which essentially constitutes self-insurance, may not be used as a method of providing financial assurance. Any surety method or insurance used to provide financial assurance for decommissioning must meet all of the following criteria:
DHS 157.15(6)(b)1.1. The surety method or insurance shall be open-ended or, if written for a specified term, renewed automatically unless 90 days or more prior to the renewal date, the issuer notifies the department, the beneficiary and the licensee of its intention not to renew. The surety method or insurance shall also provide that the full face amount be paid to the beneficiary automatically prior to the expiration without proof of forfeiture if the licensee fails to provide a replacement acceptable to the department within 30 days after receipt of notification of cancellation.
DHS 157.15(6)(b)2.2. The surety method or insurance shall be payable to a trust established for decommissioning costs. The department shall approve the trustee and the trust.
DHS 157.15 NoteNote: An acceptable trustee includes the State of Wisconsin or an entity having the authority to act as a trustee and whose trust operations are regulated and examined by a state or federal government agency.
DHS 157.15(6)(b)3.3. The surety method or insurance shall remain in effect until the department terminates the license.
DHS 157.15(6)(c)(c) External sinking fund. An external sinking fund may be used in which deposits are made at least annually, coupled with a surety method or insurance, the value of which may decrease by the amount being accumulated in the sinking fund. An external sinking fund may be in the form of a trust, escrow account, government fund, certificate of deposit or deposit of government securities. The surety or insurance provisions shall meet the requirements of par. (b).
DHS 157.15(6)(d)(d) Statement of intent. A state or local government licensee exempt under sub. (2) shall submit a written statement of intent containing a cost estimate for decommissioning or an amount based on sub. (4). The cost estimate shall indicate that funds for decommissioning will be obtained when necessary.
DHS 157.15(7)(7)Records.
DHS 157.15(7)(a)(a) A licensee shall keep the following records of information related to decommissioning of a facility in an identified location until the site is released for unrestricted use:
DHS 157.15(7)(a)1.1. Records of spills or other unusual occurrences involving the spread of radioactive contamination in and around the facility, equipment or site. The records may be limited to instances where contamination remains after any cleanup procedures or when there is reasonable likelihood that radioactive contaminants may have spread to inaccessible areas or into porous materials such as concrete. The records shall include any known information on identification of involved nuclides, quantities, forms and concentrations.
DHS 157.15(7)(a)2.2. As-built drawings and modifications of structures and equipment in restricted areas where radioactive materials are used or stored, and of locations of possible inaccessible contamination such as buried pipes that may contain radioactive contaminants. If required drawings are referenced, each relevant document does not need to be indexed individually. If drawings are not available, a licensee shall substitute appropriate records of available information concerning the areas and locations of inaccessible contamination.
DHS 157.15 NoteNote: As-built architectural and engineering drawings need to reflect the final details of the structures and equipment as they were constructed.
DHS 157.15(7)(a)3.3. Except for areas containing only sealed sources that have not leaked or where no contamination remains after a leak, or radioactive materials with half-lives of less than 65 days, a list containing all the following:
DHS 157.15(7)(a)3.a.a. All areas currently and formerly designated as restricted areas.
DHS 157.15(7)(a)3.b.b. All areas outside of restricted areas that require documentation under subd. 1.
DHS 157.15(7)(a)3.c.c. All areas outside of restricted areas where current and previous wastes have been buried as documented under s. DHS 157.31 (9).
DHS 157.15(7)(a)3.d.d. All areas outside of restricted areas that contain radioactive material such that, if the license expired, the licensee would be required to either decontaminate the area to meet the criteria for decommissioning in s. DHS 157.13 (11) (d) or apply for approval for disposal under s. DHS 157.30 (2).
DHS 157.15(7)(a)4.4. Records of the cost estimate performed for the decommissioning funding plan or the amount certified for decommissioning and records of the funding method used for assuring funds.
DHS 157.15(7)(b)(b) A licensee shall keep the records in par. (a) until the site is decommissioned and approved by the department for unrestricted use.
