(1) Each applicant for a specific license authorizing the possession and use of unsealed radioactive material of half-life greater than 120 days and in quantities exceeding 10⁵ times the applicable quantities specified in section 30197.7. A DFP shall also be submitted when a combination of isotopes is involved if R divided by 10⁵ is greater than 1 (unity rule), where R is defined as the sum of the ratios of the quantity of each isotope to the applicable value in section 30197.7; and

(2) Each holder of, or applicant for, any specific license authorizing the possession and use of sealed sources or plated foils of half-life greater than 120 days and in quantities exceeding 10¹² times the applicable quantities specified in section 30197.7, or when a combination of isotopes is involved if R, as defined in paragraph (1), divided by 10¹² is greater than 1.

(1) Submit a DFP as described in subsection (e); or

(2) Submit a certification that financial surety for decommissioning has been provided in the amount prescribed by subsection (d), using one of the methods described in subsection (g). For an applicant, this certification may state that the appropriate surety will be obtained after the application has been approved and the license issued but before the receipt of licensed material. If the applicant defers execution of the financial instrument until after the license has been issued, a signed original of the financial instrument obtained to satisfy the requirements of subsection (g) must be submitted to the Department before receipt of licensed material. If the applicant does not defer execution of the financial instrument, the applicant shall submit to the Department, as part of the certification, a signed original of the financial instrument obtained to satisfy the requirements of subsection (g).

(1) Each holder of a specific license issued on or after January 1, 1996, which is of a type described in subsections (a) or (b), shall provide financial surety for decommissioning in accordance with the criteria set forth in this section;

(2) Each holder of a specific license issued before January 1, 1996, and of a type described in subsection (a) shall submit a DFP as described in subsection (e), or a certification of financial surety for decommissioning in an amount at least equal to $1,125,000 in accordance with the criteria set forth in this section. If the licensee submits the certification of financial surety rather than a DFP, the licensee shall include a DFP in any application for license renewal;

(3) Each holder of a specific license issued before January 1, 1996, and of a type described in subsection (b) shall submit a DFP as described in subsection (e), or a certification of financial surety for decommissioning in accordance with the criteria set forth in this section;

(4) Waste collectors and waste processors, as defined in Appendix G of Title 10, Code of Federal Regulations, Part 20 (10 CFR 20), incorporated by reference in section 30253, shall provide financial surety in an amount based on a DFP as described in subsection (e). The DFP shall also include the cost of disposal of the maximum amount (in curies) of radioactive material permitted by the license, and the cost of disposal of the maximum quantity, by volume, of radioactive material which could be present at the licensee's facility at any time; and

(5) If, in surveys made under 10 CFR 20.1501(a), incorporated by reference in section 30253, residual radioactivity in the facility and environment, including the subsurface, is detected at levels that would, if left uncorrected, prevent the site from being released in accordance with the licensee's specific license, the licensee shall submit a DFP meeting the criteria specified in subsection (e) within one year of when the survey is completed. Nothing in this section may be construed to eliminate the need to comply with section 30256, to authorize the performance of actual decommissioning activities, or to establish radiological criteria for termination of a specific license.

(1) A detailed decommissioning cost estimate (DCE), in an amount reflecting:

(2) Identification of and justification for using the key assumptions contained in the DCE;

(3) A description of the method of assuring funds for decommissioning, from alternatives listed in subsection (g), including means for adjusting cost estimates and associated funding levels periodically over the life of the facility;

(4) A certification by the licensee that financial surety for decommissioning has been provided in the amount of the cost estimate for decommissioning; and

(5) A signed original of the financial instrument obtained to satisfy the requirements of subsection (g), unless a previously submitted and accepted financial instrument continues to cover the cost estimate for decommissioning.

(1) Spills of radioactive material producing additional residual radioactivity in onsite subsurface material;

(2) Waste inventory increasing above the amount previously estimated;

(3) Waste disposal costs increasing above the amount previously estimated;

(4) Facility modifications;

(5) Changes in authorized possession limits;

(6) Actual remediation costs that exceed the previous cost estimate;

(7) Onsite disposal; and

(8) Use of a settling pond.

(1) Prepayment. Prepayment is the deposit prior to the start of operation, into an account segregated from licensee assets and outside the licensee's administrative control, of cash or liquid assets such that the amount of funds would be sufficient to pay decommissioning costs. Prepayment shall be in the form of a trust or certificate of deposit.

(2) A surety method, insurance, or other guarantee method. These methods guarantee that decommissioning costs will be paid. A surety method shall be in the form of a surety bond, or letter of credit. For bonds, the Payment Surety Bond form specified in title 11, California Code of Regulations, section 80.3 shall be used. Other guarantee methods are as specified in sections 30197.3 through 30197.6, described as follows: a parent company guarantee of funds for decommissioning costs based on a financial test may be used if the guarantee and test are as contained in section 30197.3; for commercial corporations that issue bonds, a guarantee of funds by the applicant or licensee for decommissioning costs based on a financial test may be used if the guarantee and test are as contained in section 30197.4; for commercial companies that do not issue bonds, a guarantee of funds by the applicant or licensee for decommissioning costs may be used if the guarantee and test are as contained in section 30197.5; and, for nonprofit entities, such as colleges, universities, and nonprofit hospitals, a guarantee of funds by the applicant or licensee may be used if the guarantee and test are as contained in section 30197.6. Except for an external sinking fund, a parent company guarantee or a guarantee by the applicant or licensee may not be used in combination with any other financial methods used to satisfy the requirements of this section. A guarantee by the applicant or licensee may not be used in any situation where the applicant or licensee has a parent company holding majority control of the voting stock of the company. Any surety method or insurance used to provide financial surety for decommissioning must remain in effect until the Department has terminated the license, and be:

(3) An external sinking fund in which deposits are made at least annually, coupled with a surety method, insurance, or other guarantee method, the value of which may decrease by the amount being accumulated in the sinking fund. An external sinking fund is a fund established and maintained by setting aside funds periodically in an account segregated from licensee assets and outside the licensee's administrative control, in which the total amount of funds would be sufficient to pay decommissioning costs at the time termination of operation is expected. An external sinking fund must be in the form of a trust. If another guarantee method specified in sections 30197.3 through 30197.6 is used, no surety or insurance may be combined with the external sinking fund. The surety, insurance or other guarantee provisions must be as stated in paragraph (2).

(4) In the case of State or local government licensees, a statement of intent containing a cost estimate for decommissioning or an amount based on the table in subsection (d), and indicating that funds for decommissioning will be obtained when necessary.

(5) When a government entity is assuming custody and ownership of a site, an arrangement that is deemed acceptable by such government entity.
