3.9.2 The applicant's proposed equipment, facilities, and procedures are adequate to minimize danger to public health and safety or property and the applicant's facilities are permanently located in Colorado;

3.9.3 The issuance of the license will not be inimical to the health and safety of the public;

3.9.4 The applicant satisfies any applicable special requirements in parts 3, 5, 7, 16, 19, and 22; and

3.9.5 The applicant has established Department-approved financial assurance warranties in accordance with the following requirements.

3.9.5.1 A signed executed original copy of each warranty required by this part shall be furnished to and approved by the Department prior to the issuance of a new license, or any amendment or renewal of an existing license.

3.9.5.2 The Department may require any licensee to furnish a decommissioning warranty in a dollar amount determined by the Department as necessary to protect public health and safety, to ensure corrective action during operation, to ensure decontamination and decommissioning of a facility and disposal of radioactive materials in the event of abandonment, default or inability of the licensee to meet the requirements of the Act, these regulations, or the license.

3.9.5.3 The following specific licensees are required to furnish decommissioning warranties:

(1) Each licensee authorized to possess and use greater than 370 MBq (10 mCi) of source material in a readily dispersible form; and

(2) Each licensee authorized to possess and use radioactive material with a half-life greater than 120 days, in quantities:

(a) Greater than 10³ times the applicable quantity of Schedule 3B in unsealed form. For a combination of isotopes if R divided by 10³ is greater than 1 (unity rule), where R is defined here as the sum of the ratios of the quantity of each isotope to the applicable value in Schedule 3B.

(b) Greater than 10¹⁰ times the applicable quantity of Schedule 3B in sealed sources or plated foils. For a combination of isotopes if R divided by 10¹⁰ is greater than 1 (unity rule), where R is defined in 3.9.5.3(2)(a).

(c) 370 Bq (0.01 µCi) shall be used as the Schedule 3B value for any alpha emitting radionuclide not listed in Schedule 3B, or mixtures of alpha emitters of unknown composition, for the purpose of determining if the quantity of licensed radioactive material requires a decommissioning warranty or a decommissioning funding plan as defined in 3.9.6.

(3) Former U.S. Atomic Energy Commission or NRC licensed facilities;

(4) Radioactive waste collection and/or processing licensees;

(5) Radioactive waste disposal licensees;

(6) Source material milling licensees;

(7) Ore refineries; and

(8) Other persons with, or applicants for, a specific license as determined by the Department.

3.9.5.4 Acceptable Financial Assurance Methods.

(1) Financial assurance warranties shall contain provisions which are acceptable to the Department for:

(a) Defining the amount and term of the warranty;

(b) Providing written notification to the Department by the warrantor at least ninety (90) days prior to cancellation, termination, or revocation of the warranty; and

(c) Converting the warranty into cash upon forfeiture of the warranty, and

(2) Financial assurance warranties shall be in the form of a cash deposit, prepayment of a trust, escrow account, government fund, certificate of deposit, or deposit of government securities.

(a) 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; or

(3) Financial assurance warranties which involve a guarantee method to ensure that costs will be paid should the licensee default shall be in a form as described below:

(a) A bond issued by a fidelity or surety company consistent with the provisions of Section 25-11-110(6)(b)(l), CRS;

(b) An irrevocable "letter of credit" or "line of credit" issued by a recognized financial institution whose financial condition and commitment are established to the satisfaction of the Department;

(c) For a decommissioning warranty, a guarantee of funds by the applicant, licensee, or parent company which satisfies the requirements listed below. However, this self-guarantee shall not apply to uranium or thorium milling licensees.

(i) The Department may accept a parent company guarantee of funds for decommissioning costs based upon a financial test of the parent company and a written guarantee as contained in Appendix 3F.

(ii) The Department may accept an applicant or licensee guarantee of funds for decommissioning costs based upon a financial test of the applicant or licensee and a written guarantee as contained in Appendix 3G.

(iii) A guarantee by the applicant, licensee, or parent company may not be used in combination with other financial methods to satisfy the requirements of this section.

(iv) 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; or

(4) Financial assurance warranties which involve an external sinking fund shall be in a form 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.

(a) 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.

(b) An external sinking fund may be in the form of a trust, escrow account, government fund, certificate of deposit, or deposit of government securities; or

(5) Financial assurance warranties previously provided to any State, Federal and/or local governing bodies concerning activities subject to license under these regulations, where the amount, terms, and conditions of such financial assurance warranties have been established to the satisfaction of the Department and in accordance with the requirements of 3.9.5; or

(6) Except for the guarantee of funds noted in 3.9.5.4(3), combinations of the above may be used to establish an acceptable financial assurance warranty.

(7) The term of the financial assurance warranty shall be open-ended or shall have provisions for automatic renewal until termination of the license by the Department, unless it can be demonstrated that another arrangement would provide an equivalent level of assurance.

(8) The value of the financial assurance warranty must not be dependent upon the success, profitability, or continued operation of the licensed business or operation.

3.9.5.5 The amount of funds to be provided by such decommissioning warranties shall be based on Department-approved cost estimates and shall

(1) Include the disposal of radioactive materials;

(2) Include decontamination and decommissioning of buildings, facilities and the site to levels which would allow unrestricted use of these areas upon decommissioning;

(3) Include the reclamation of tailings and/or waste disposal areas in accordance with technical criteria delineated in Parts 3, 4 and/or 18, as appropriate;

(4) Take into account total costs that would be incurred if an independent contractor were hired to dispose of radioactive materials and perform decontamination, decommissioning, and reclamation work, including:

(a) The cost of removal and/or disposal of radioactive material, or a radioactivity-inducing machine, which is or would be generated, stored, processed or otherwise present at the facility or site; and

(b) The probable extent of contamination through the possession or use of radioactive material, at or adjacent to the facility or site, and the probable cost of removal of such contamination; and

(5) Include reasonable administrative costs, including indirect costs, incurred by the Department in conducting or overseeing the decontamination, decommissioning, and disposal activities, and to cover the Department's reasonable attorney costs that may be incurred in successfully revoking, foreclosing, or realizing the decommissioning warranties established by the licensee in accordance with Part 3.

3.9.5.6 The licensee shall provide in writing to the Department, no later than June 30th of each calendar year, an annual report demonstrating proof of the value of existing financial warranties and any licensee-proposed changes to the financial assurance warranties, including updated decommissioning funding plans, cost estimates, or the type of warranty. The annual report shall describe any changes in operations, estimated costs, or any other circumstances that may affect the amount of the required financial assurance warranties, including any increased or decreased costs attributable to inflation.

3.9.5.7 Each licensee's financial assurance warranties shall be subject to review annually by the Department to assure the continued adequacy of each warranty. Public notice of the submittal of the licensee's annual report shall be posted on the Department's web site and published by the licensee in the local paper of general circulation. Any person may submit written comments to the Department concerning the adequacy of any financial assurance warranties. The act of submitting such comments does not provide a right to administrative appeal concerning the financial assurance warranties.

3.9.5.8 The Department will determine if the licensee must adjust the amount of the warranty to account for increases or decreases in cost estimates resulting from:

(1) Inflation or deflation;

(2) Changes in engineering plans;

(3) Activities performed;

(4) Spills, leakage or migration of radioactive material producing additional contamination in onsite subsurface material that must be remediated to meet applicable remediation criteria;

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

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

(7) Facility modifications;

(8) Changes in authorized possession limits;

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

(10) Onsite disposal; and

(11) Changes in any other conditions affecting disposal, decontamination, and decommissioning costs.

3.9.5.9 Regardless of whether reclamation (disposal, decontamination and decommissioning) is phased through the life of the licensed operations or takes place at the end of operations, an appropriate portion of surety liability must be retained until final compliance with the reclamation plan is determined by the Department.

3.9.5.10 The appropriate portion of surety liability retained until final compliance with the reclamation plan is determined will be at least sufficient at all times to cover the costs of decommissioning and reclamation of the areas that are expected to be disturbed before the next license renewal. The term of the surety mechanism must be open ended, unless it can be demonstrated that another arrangement would provide an equivalent level of assurance. This assurance would be provided with a surety instrument which is written for a specified time (e.g., 5 years) and which must be automatically renewed unless the surety notifies the beneficiary (the NRC or the Department) and the principal (the licensee) with reasonable time (e.g., 90 days) before the renewal date of their intention not to renew. In such a situation the surety requirement still exists and the licensee would be required to submit an acceptable replacement surety within a brief time to allow at least 60 days for the regulatory agency to collect.

3.9.5.11 Proof of forfeiture must not be necessary to collect the surety. In the event the licensee can not provide an acceptable replacement surety within the required time, the surety shall be automatically collected before its expiration. The surety instrument must provide for collection of the full face amount immediately on demand without reduction for any reason, except for trustee fees and expenses provided for in a trust agreement, and that the surety will not refuse to make full payment. The conditions described previously would have to be clearly stated on any surety instrument which is not open ended, and must be agreed to by all parties. Financial surety arrangements generally acceptable to the Department are:

(1) Trust funds;

(2) Surety bonds;

(3) Irrevocable letters of credit; and

(4) Combinations of the financial surety arrangements or other types of arrangements as may be approved by the Department. If a trust is not used, then a standby trust must be set up to receive funds in the event the NRC or Department exercises its right to collect the surety. The surety arrangement and the surety or trustee, as applicable, must be acceptable to the Department. Self insurance, or any arrangement which essentially constitutes self insurance (e.g., a contract with a State or Federal agency), will not satisfy the surety requirement because this provides no additional assurance other than that which already exists through license requirements.

3.9.5.12 With the approval of the Department, a licensee may reduce the amount of a decommissioning warranty as decommissioning activities are completed in accordance with an approved decommissioning plan and/or to reflect current site conditions and license authorizations.

3.9.5.13 The licensee shall have sixty days after the date of written notification by the Department of a required adjustment to establish a warranty fulfilling all new requirements unless granted an extension by the Department. If the licensee disputes the amount of the required financial assurance warranties, the licensee may request a hearing to be conducted in accordance with section 24-4-105, CRS.

3.9.5.14 If the licensee requests a hearing, no new material ore or other radioactive material may be brought on site for processing or disposal and no new radioactive material may be processed until the licensee's dispute over the financial assurance warranty is resolved, unless the licensee posts a bond in a form approved by the Department equal to the amount in dispute.

LONG-TERM CARE WARRANTY

3.9.5.15 In addition to the decommissioning warranty required by 3.9.5.2, the Department may require any licensee to provide a long-term care warranty if the licensed facility will remain a disposal site for radioactive materials subsequent to the termination of the license, or the license will be terminated using criteria in 4.61.3 or 4.61.4.

(1) Except as provided in 3.9.5.15(2), the following specific licensees are required to provide long-term care warranties:

(a) Radioactive waste disposal licensees;

(b) Commercial radioactive waste handling and/or packaging licensees;

(c) Source material milling licensees; and

(d) Formerly U.S. Atomic Energy Commission or U.S. Nuclear Regulatory Commission-licensed facilities;

(2) A long-term care warranty is not required for a licensee identified in 3.9.5.15(1) if the disposition of radioactive materials by the licensee is made in such a manner as the Department determines does not require long-term monitoring and maintenance of the site.

(3) The long-term care warranty shall be in a form as described in 3.9.5.4.

(4) The amount of funds to be provided by such long-term care warranties shall be based on Department-approved cost estimates and must be enough that with an assumed one percent annual real interest rate, the annual interest earnings will be sufficient to cover the annual costs of site surveillance, including reasonable administrative costs incurred, in perpetuity, subsequent to the termination of the license.

(a) For each source material mill licensee, the long-term care warranty must have a minimum value equivalent to $250,000 in 1978 dollars.

(i) The value of the long-term care warranty shall be adjusted annually to recognize inflation.

(ii) The inflation rate to be used for this adjustment is that indicated by the change in the consumer price index published by the U.S. Department of Labor, Bureau of Labor Statistics.

(iii) The Department may use other indicators of the inflation rate if reasonable; provided, however, that the license shall not terminate unless the amount of the long-term care warranty is acceptable to the licensing agency and site caretaker.

(b) Cost estimates for facilities and sites requiring long-term care subsequent to license termination are to be based on the final disposition of wastes such that ongoing active maintenance is not necessary to preserve isolation.

(i) It is expected that, as a minimum, annual site inspections shall be conducted to confirm the integrity of the stabilized waste systems and to determine the need, if any, for maintenance and/or monitoring.

(ii) Cost estimates shall be adjusted if more frequent site inspections are required based on an evaluation of a particular site.

(c) For sites decommissioned in accordance with the provisions of 4.61.3 or 4.61.4, cost estimates for long-term care subsequent to license termination must be sufficient to enable the Department, a responsible government agency, or an independent third party to:

(i) Perform periodic site inspections no less frequently than each five years;

(ii) Assure the continuation of institutional controls; and

(iii) Assume responsibilities and carry out any necessary control and maintenance of the site. Cost estimates shall be adjusted if more frequent site inspections are required based on an evaluation of a particular site and the institutional controls established for that site.

(5) Whenever the Department determines that a licensee's disposal, decommissioning and decontamination requirements have been satisfied, provisions shall be made for transferring custody of the site and the long-term care warranty funds for that license in accordance with the act.

(a) If the value of the long-term care warranty funds exceeds the amount required by the government agency overseeing the long-term care of the site, then all such excess amounts shall be returned to the licensee.

3.9.6 Decommissioning Funding Plan Required.

3.9.6.1 Each applicant for and holder of a license authorizing the possession and use unsealed radioactive materials with half-life greater than 120 days and in quantities greater than 10⁵ times the applicable quantity of Schedule 3B, shall establish a Department-approved decommissioning funding plan to assure the availability of funds for decommissioning activities conducted over the life of the licensed facility. 370 Bq (0.01 µCi) shall be used as the Schedule 3B value for any alpha emitting radionuclide not listed in Schedule 3B, or mixtures of alpha emitters of unknown composition. A decommissioning funding plan is also required for licensees authorized a combination of isotopes if R divided by 10⁵ is greater than 1 (unity rule), where R is defined in 3.9.5.3(2)(a).

3.9.6.2 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 greater than 10¹² times the applicable quantity in Schedule 3B shall establish a Department-approved decommissioning funding plan to assure the availability of funds for decommissioning activities conducted over the life of the licensed facility. 370 Bq (0.01 µCi) shall be used as the Schedule 3B value for any alpha emitting radionuclide not listed in Schedule 3B, or mixtures of alpha emitters of unknown composition. The decommissioning funding plan is also required for licensees authorized for a combination of isotopes if R divided by 10¹² is greater than 1 (unity rule), where R is defined as in 3.9.5.3(2)(a).

3.9.6.3 Waste collectors and waste processors, as defined in Part 4, Appendix D, shall establish a Department-approved decommissioning funding plan to assure the availability of funds for decommissioning activities conducted over the life of the licensed facility.

(1) The decommissioning funding plan must include the cost of disposal of the maximum radioactivity (becquerel or curie) of radioactive material permitted by the license, and the cost of disposal of the maximum quantity, by volume, of radioactive material that could be present at the licensee's facility at any time, in addition to the cost to remediate the licensee's site to meet the license termination criteria of Part 4.

3.9.6.4 Each decommissioning funding plan must be submitted for review and approval by the Department and must contain:

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

(a) The cost of an independent contractor to perform all decommissioning activities;

(b) The cost of meeting the 4.61.2 criteria for unrestricted use, provided that, if the applicant or licensee can demonstrate its ability to meet the provisions of 4.61.3 for restricted use, the cost estimate may be based on meeting the 4.61.3 restricted use criteria;

(c) The volume of onsite subsurface material containing residual radioactivity that will require remediation to meet the criteria for license termination; and

(d) An adequate contingency factor.

(i) Identification of and justification for using the key assumptions contained in the detailed cost estimate;

(ii) A description of the method of assuring funds for decommissioning as required in this section, including means for adjusting cost estimates and associated funding levels periodically over the life of the facility.

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

(iv) A signed original, or if permitted, a copy, of the financial instrument obtained to satisfy the requirements of this section (unless a previously submitted and accepted financial instrument continues to cover the cost estimate for decommissioning).

3.9.6.5 At the time of license renewal and at intervals not to exceed three years, the decommissioning funding plan must be resubmitted with adjustments as necessary to account for changes in costs and the extent of contamination. If the amount of financial assurance will be adjusted downward, this can not be done until the updated decommissioning funding plan is approved. The decommissioning funding plan must update the information submitted with the original or prior approved plan, and must specifically consider the effect of the following events on decommissioning costs:

(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.

3.9.6.6 The decommissioning funding plan must also include a certification by the licensee that funding for decommissioning activities has been provided for in the amount of the cost estimate for decommissioning.

(1) For an applicant, this certification may state that the appropriate assurance will be obtained after the application has been approved and the license issued, but prior to the receipt or possession of radioactive material.

(2) A signed original of the financial instrument shall be submitted to the Department.

3.9.7 In the case of an application for a license for (1) source material milling, (2) commercial waste storage, treatment or disposal by incineration, (3) transfer for disposal of waste from incineration, (4) commercial waste disposal by land burial or by underground injection, or for (5) the conduct of any other activity which the Department determines will significantly affect the quality of the human environment, the Department, before commencement of construction, on the basis of information filed and evaluations made, has concluded, after weighing the environmental, economic, technical and other benefits against environmental costs and considering available alternatives, that the action called for is the issuance of the proposed license with any appropriate conditions to protect environmental values.

3.9.7.1 Commencement of construction prior to this conclusion is grounds for denial of a license to possess and use source and byproduct material in the plant or facility.

3.9.8 Commencement of construction prior to the issuance of a license, or of an amendment or renewal thereof, or of an exemption under the requirements of 3.8.7, may be grounds for denial of such license, amendment or renewal.

3.9.9 Reserved.

3.9.10 License Hearings.

3.9.10.1 There shall be an opportunity for public hearings to be held in the following circumstances in accordance with the procedures in 24-4-104 and-105, CRS. and this paragraph:
