R315-265-145. Financial Requirements -- Financial Assurance for Post-Closure Care

  By the effective date of these regulations, an owner or operator of a facility with a hazardous waste disposal unit must establish financial assurance for post-closure care of the disposal unit(s).

  (a) Post-closure trust fund.

  (1) An owner or operator may satisfy the requirements of Section R315-265-145 by establishing a post-closure trust fund which conforms to the requirements of Subsection R315-265-145(a) and submitting an originally signed duplicate of the trust agreement to the Director. The trustee shall be an entity which has the authority to act as a trustee and whose trust operations are regulated and examined by a Federal or Utah agency.

  (2) The wording of the trust agreement shall be identical to the wording specified in Subsection R315-264-151(a)(1), and the trust agreement shall be accompanied by a formal certification of acknowledgment, for example see Subsection R315-264-151(a)(2). Schedule A of the trust agreement shall be updated within 60 days after a change in the amount of the current post-closure cost estimate covered by the agreement.

  (3) Payments into the trust fund shall be made annually by the owner or operator over the 20 years beginning with the effective date of these regulations or over the remaining operating life of the facility as estimated in the closure plan, whichever period is shorter; this period is hereafter referred to as the "pay-in period." The payments into the post-closure trust fund shall be made as follows:

  (i) The first payment shall be made by the effective date of these regulations, except as provided in Subsection R315-265-145(a)(5). The first payment shall be at least equal to the current post-closure cost estimate, except as provided in Subsection R315-265-145(f), divided by the number of years in the pay-in period.

  (ii) Subsequent payments shall be made no later than 30 days after each anniversary date of the first payment. The amount of each subsequent payment must be determined by this formula: Next payment = (CE-CV)/Y, where CE is the current post-closure cost estimate, CV is the current value of the trust fund, and Y is the number of years remaining in the pay-in period.

  (4) The owner or operator may accelerate payments into the trust fund or he may deposit the full amount of the current post-closure cost estimate at the time the fund is established. However, he shall maintain the value of the fund at no less than the value that the fund would have if annual payments were made as specified in Subsection R315-265-145(a)(3).

  (5) If the owner or operator establishes a post-closure trust fund after having used one or more alternate mechanisms specified in this section, his first payment shall be in at least the amount that the fund would contain if the trust fund were established initially and annual payments made as specified in Subsection R315-265-145 (a)(3).

  (6) After the pay-in period is completed, whenever the current post-closure cost estimate changes during the operating life of the facility, the owner or operator shall compare the new estimate with the trustee's most recent annual valuation of the trust fund. If the value of the fund is less than the amount of the new estimate, the owner or operator, within 60 days after the change in the cost estimate, shall either deposit an amount into the fund so that its value after this deposit at least equals the amount of the current post-closure cost estimate, or obtain other financial assurance as specified in Section R315-265-145 to cover the difference.

  (7) During the operating life of the facility, if the value of the trust fund is greater than the total amount of the current post-closure cost estimate, the owner or operator may submit a written request to the Director for release of the amount in excess of the current post-closure cost estimate.

  (8) If an owner or operator substitutes other financial assurance as specified in this section for all or part of the trust fund, he may submit a written request to the Director for release of the amount in excess of the current post-closure cost estimate covered by the trust fund.

  (9) Within 60 days after receiving a request from the owner or operator for release of funds as specified in Subsections R315-265-145(a) (7) or (8), the Director will instruct the trustee to release to the owner or operator such funds as the Director specifies in writing.

  (10) During the period of post-closure care, the Director may approve a release of funds if the owner or operator demonstrates to the Director that the value of the trust fund exceeds the remaining cost of post-closure care.

  (11) An owner or operator or any other person authorized to conduct post-closure care may request reimbursements for post-closure expenditures by submitting itemized bills to the Director. Within 60 days after receiving bills for post-closure care activities, the Director will instruct the trustee to make reimbursements in those amounts as the Director specifies in writing, if the Director determines that the post-closure expenditures are in accordance with the approved post-closure plan or otherwise justified. If the Director does not instruct the trustee to make such reimbursements, he will provide the owner or operator with a detailed written statement of reasons.

  (12) The Director will agree to termination of the trust when:

  (i) An owner or operator substitutes alternate financial assurance as specified in this section; or

  (ii) The Director releases the owner or operator from the requirements of Section R315-265-145 in accordance with Subsection R315-265-145(h).

  (b) Surety bond guaranteeing payment into a post-closure trust fund.

  (1) An owner or operator may satisfy the requirements of Section R315-265-145 by obtaining a surety bond which conforms to the requirements of Subsection R315-265-145(b) and submitting the bond to the Director. The surety company issuing the bond must, at a minimum, be among those listed as acceptable sureties on Federal bonds in Circular 570 of the U.S. Department of the Treasury.

  (2) The wording of the surety bond must be identical to the wording specified in Subsection R315-264-151(b).

  (3) The owner or operator who uses a surety bond to satisfy the requirements of this section shall also establish a standby trust fund. Under the terms of the bond, all payments made thereunder will be deposited by the surety directly into the standby trust fund in accordance with instructions from the Director. This standby trust fund shall meet the requirements specified in Subsection R315-265-145(a), except that:

  (i) An originally signed duplicate of the trust agreement shall be submitted to the Director with the surety bond; and

  (ii) Until the standby trust fund is funded pursuant to the requirements of Section R315-265-145, the following are not required by these regulations:

  (A) Payments into the trust fund as specified in Subsection R315-265-145(a);

  (B) Updating of Schedule A of the trust agreement, see Subsection R315-264-151(a), to show current post-closure cost estimates;

  (C) Annual valuations as required by the trust agreement; and

  (D) Notices of nonpayment as required by the trust agreement.

  (4) The bond shall guarantee that the owner or operator will:

  (i) Fund the standby trust fund in an amount equal to the penal sum of the bond before the beginning of final closure of the facility; or

  (ii) Fund the standby trust fund in an amount equal to the penal sum within 15 days after an administrative order to begin final closure issued by the Director becomes final, or within 15 days after an order to begin final closure is issued by a U.S. district court or other court of competent jurisdiction; or

  (iii) Provide alternate financial assurance as specified in Section R315-265-145, and obtain the Director's written approval of the assurance provided, within 90 days after receipt by both the owner or operator and the Director of a notice of cancellation of the bond from the surety.

  (5) Under the terms of the bond, the surety will become liable on the bond obligation when the owner or operator fails to perform as guaranteed by the bond.

  (6) The penal sum of the bond shall be in an amount at least equal to the current post-closure cost estimate, except as provided in Subsection R315-265-145(f).

  (7) Whenever the current post-closure cost estimate increases to an amount greater than the penal sum, the owner or operator, within 60 days after the increase, shall either cause the penal sum to be increased to an amount at least equal to the current post-closure cost estimate and submit evidence of such increase to the Director, or obtain other financial assurance as specified in Section R315-265-145 to cover the increase. Whenever the current post-closure cost estimate decreases, the penal sum may be reduced to the amount of the current post-closure cost estimate following written approval by the Director.

  (8) Under the terms of the bond, the surety may cancel the bond by sending notice of cancellation by certified mail to the owner or operator and to the Director. Cancellation may not occur, however, during the 120 days beginning on the date of receipt of the notice of cancellation by both the owner or operator and the Director, as evidenced by the return receipts.

  (9) The owner or operator may cancel the bond if the Director has given prior written consent based on his receipt of evidence of alternate financial assurance as specified in Section R315-265-145.

  (c) Post-closure letter of credit.

  (1) An owner or operator may satisfy the requirements of Section R315-265-145 by obtaining an irrevocable standby letter of credit which conforms to the requirements of Subsection R315-265-145(c) and submitting the letter to the Director. The issuing institution shall be an entity which has the authority to issue letters of credit and whose letter-of-credit operations are regulated and examined by a Federal or Utah agency.

  (2) The wording of the letter of credit shall be identical to the wording specified in Subsection R315-264-151(d).

  (3) An owner or operator who uses a letter of credit to satisfy the requirements of this section shall also establish a standby trust fund. Under the terms of the letter of credit, all amounts paid pursuant to a draft by the Director will be deposited by the issuing institution directly into the standby trust fund in accordance with instructions from the Director. This standby trust fund must meet the requirements of the trust fund specified in Subsection R315-265-145(a), except that:

  (i) An originally signed duplicate of the trust agreement shall be submitted to the Director with the letter of credit; and

  (ii) Unless the standby trust fund is funded pursuant to the requirements of Section R315-265-145, the following are not required by these regulations:

  (A) Payments into the trust fund as specified in Subsection R315-265-145(a);

  (B) Updating of Schedule A of the trust agreement, see Subsection R315-264-151(a), to show current post-closure cost estimates;

  (C) Annual valuations as required by the trust agreement; and

  (D) Notices of nonpayment as required by the trust agreement.

  4) The letter of credit shall be accompanied by a letter from the owner or operator referring to the letter of credit by number, issuing institution, and date, and providing the following information: The EPA Identification Number, name, and address of the facility, and the amount of funds assured for post-closure care of the facility by the letter of credit.

  (5) The letter of credit shall be irrevocable and issued for a period of at least one year. The letter of credit shall provide that the expiration date will be automatically extended for a period of at least one year unless, at least 120 days before the current expiration date, the issuing institution notifies both the owner or operator and the Director by certified mail of a decision not to extend the expiration date. Under the terms of the letter of credit, the 120 days will begin on the date when both the owner or operator and the Director have received the notice, as evidenced by the return receipts.

  (6) The letter of credit shall be issued in an amount at least equal to the current post-closure cost estimate, except as provided in Subsection R315-265-145(f).

  (7) Whenever the current post-closure cost estimate increases to an amount greater than the amount of the credit during the operating life of the facility, the owner or operator, within 60 days after the increase, shall either cause the amount of the credit to be increased so that it at least equals the current post-closure cost estimate and submit evidence of such increase to the Director, or obtain other financial assurance as specified in Section R315-265-145 to cover the increase. Whenever the current post-closure cost estimate decreases during the operating life of the facility, the amount of the credit may be reduced to the amount of the current post-closure cost estimate following written approval by the Director.

  (8) During the period of post-closure care, the Director may approve a decrease in the amount of the letter of credit if the owner or operator demonstrates to the Director that the amount exceeds the remaining cost of post-closure care.

  (9) Following a final administrative determination that the owner or operator has failed to perform post-closure care in accordance with the approved post-closure plan and other permit requirements, the Director may draw on the letter of credit.

  (10) If the owner or operator does not establish alternate financial assurance as specified in Section R315-265-145 and obtain written approval of such alternate assurance from the Director within 90 days after receipt by both the owner or operator and the Director of a notice from the issuing institution that it has decided not to extend the letter of credit beyond the current expiration date, the Director will draw on the letter of credit. The Director may delay the drawing if the issuing institution grants an extension of the term of the credit. During the last 30 days of any such extension the Director will draw on the letter of credit if the owner or operator has failed to provide alternate financial assurance as specified in Section R315-265-145 and obtain written approval of such assurance from the Director.

  (11) The Director will return the letter of credit to the issuing institution for termination when:

  (i) An owner or operator substitutes alternate financial assurance as specified in Section R315-265-145; or

  (ii) The Director releases the owner or operator from the requirements of Section R315-265-145 in accordance with Subsection R315-265-145(h).

  (d) Post-closure insurance.

  (1) An owner or operator may satisfy the requirements of Section R315-265-145 by obtaining post-closure insurance which conforms to the requirements of Subsection R315-265-145(d) and submitting a certificate of such insurance to the Director. By the effective date of these regulations the owner or operator shall submit to the Director a letter from an insurer stating that the insurer is considering issuance of post- closure insurance conforming to the requirements of Subsection R315-265-145(d) to the owner or operator. Within 90 days after the effective date of these regulations, the owner or operator shall submit the certificate of insurance to the Director or establish other financial assurance as specified in Section R315-265-145. At a minimum, the insurer shall be licensed to transact the business of insurance, or eligible to provide insurance as an excess or surplus lines insurer, in one or more States.

  (2) The wording of the certificate of insurance shall be identical to the wording specified in Subsection R315-264-151(e).

  (3) The post-closure insurance policy shall be issued for a face amount at least equal to the current post-closure cost estimate, except as provided in Subsection R315-265-145(f). The term "face amount" means the total amount the insurer is obligated to pay under the policy. Actual payments by the insurer will not change the face amount, although the insurer's future liability will be lowered by the amount of the payments.

  (4) The post-closure insurance policy shall guarantee that funds will be available to provide post-closure care of the facility whenever the post-closure period begins. The policy shall also guarantee that once post-closure care begins the insurer will be responsible for paying out funds, up to an amount equal to the face amount of the policy, upon the direction of the Director, to such party or parties as the Director specifies.

  (5) An owner or operator or any other person authorized to perform post-closure care may request reimbursement for post-closure care expenditures by submitting itemized bills to the Director. Within 60 days after receiving bills for post-closure care activities, the Director will instruct the insurer to make reimbursements in those amounts as the Director specifies in writing, if the Director determines that the post-closure expenditures are in accordance with the approved post-closure plan or otherwise justified. If the Director does not instruct the insurer to make such reimbursements, he will provide a detailed written statement of reasons.

  (6) The owner or operator shall maintain the policy in full force and effect until the Director consents to termination of the policy by the owner or operator as specified in Subsection R315-265-145(d)(11). Failure to pay the premium, without substitution of alternate financial assurance as specified in the section, will constitute a significant violation of these regulations, warranting such remedy as the Director deems necessary. Such violation will be deemed to begin upon receipt by the Director of a notice of future cancellation, termination, or failure to renew due to nonpayment of the premium, rather than upon the date of expiration.

  (7) Each policy shall contain a provision allowing assignment of the policy to a successor owner or operator. Such assignment may be conditional upon consent of the insurer, provided such consent is not unreasonably refused.

  (8) The policy shall provide that the insurer may not cancel, terminate, or fail to renew the policy except for failure to pay the premium. The automatic renewal of the policy must, at a minimum, provide the insured with the option of renewal at the face amount of the expiring policy. If there is a failure to pay the premium, the insurer may elect to cancel, terminate, or fail to renew the policy by sending notice by certified mail to the owner or operator and the Director. Cancellation, termination, or failure to renew may not occur, however, during the 120 days beginning with the date of receipt of the notice by both the Director and the owner or operator, as evidenced by the return receipts. Cancellation, termination, or failure to renew may not occur and the policy will remain in full force and effect in the event that on or before the date of expiration:

  (i) The Director deems the facility abandoned; or

  (ii) Interim status is terminated or revoked; or

  (iii) Closure is ordered by the Director or a U.S. district court or other court of competent jurisdiction; or

  (iv) The owner or operator is named as debtor in a voluntary or involuntary proceeding under Title 11 (Bankruptcy), U.S. Code; or

  (v) The premium due is paid.

  (9) Whenever the current post-closure cost estimate increases to an amount greater than the face amount of the policy during the operating life of the facility, the owner or operator, within 60 days after the increase, shall either cause the face amount to be increased to an amount at least equal to the current post-closure cost estimate and submit evidence of such increase to the Director, or obtain other financial assurance as specified in Section R315-265-145 to cover the increase. Whenever the current post-closure cost estimate decreases during the operating life of the facility, the face amount may be reduced to the amount of the current post-closure cost estimate following written approval by the Director.

  (10) Commencing on the date that liability to make payments pursuant to the policy accrues, the insurer will thereafter annually increase the face amount of the policy. Such increase shall be equivalent to the face amounts of the policy, less any payments made, multiplied by an amount equivalent to 85 percent of the most recent investment rate or of the equivalent coupon-issue yield announced by the U.S. Treasury for 26-week Treasury securities.

  (11) The Director will give written consent to the owner or operator that he may terminate the insurance policy when:

  (i) An owner or operator substitutes alternate financial assurance as specified in Section R315-265-145; or

  (ii) The Director releases the owner or operator from the requirements of Section R315-265-145 in accordance with Subsection R315-265-145(h).

  (e) Financial test and corporate guarantee for post-closure care.

  (1) An owner or operator may satisfy the requirements of Section R315-265-145 by demonstrating that he passes a financial test as specified in Subsection R315-265-145(e). To pass this test the owner or operator shall meet the criteria either of Subsections R315-265-145(e)(1)(i) or (ii):

  (i) The owner or operator shall have:

  (A) Two of the following three ratios: a ratio of total liabilities to net worth less than 2.0; a ratio of the sum of net income plus depreciation, depletion, and amortization to total liabilities greater than 0.1; and a ratio of current assets to current liabilities greater than 1.5; and

  (B) Net working capital and tangible net worth each at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates; and

  (C) Tangible net worth of at least $10 million; and

  (D) Assets in the United States amounting to at least 90 percent of his total assets or at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates.

  (ii) The owner or operator shall have:

  (A) A current rating for his most recent bond issuance of AAA, AA, A, or BBB as issued by Standard and Poor's or Aaa, Aa, A, or Baa as issued by Moody's; and

  (B) Tangible net worth at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates; and

  (C) Tangible net worth of at least $10 million; and

  (D) Assets located in the United States amounting to at least 90 percent of his total assets or at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates.

  (2) The phrase "current closure and post-closure cost estimates" as used in Subsection R315-265-145(e)(1) refers to the cost estimates required to be shown in paragraphs 1-4 of the letter from the owner's or operator's chief financial officer, for example see Subsection R315-264-151(f). The phrase "current plugging and abandonment cost estimates" as used in Subsection R315-265-145(e)(1) refers to the cost estimates required to be shown in paragraphs 1-4 of the letter from the owner's or operator's chief financial officer, for example see 40 CFR 144.70(f).

  (3) To demonstrate that he meets this test, the owner or operator shall submit the following items to the Director:

  (i) A letter signed by the owner's or operator's chief financial officer and worded as specified in Subsection R315-264-151(f); and

  (ii) A copy of the independent certified public accountant's report on examination of the owner's or operator's financial statements for the latest completed fiscal year; and

  (iii) A special report from the owner's or operator's independent certified public accountant to the owner or operator stating that:

  (A) He has compared the data which the letter from the chief financial officer specifies as having been derived from the independently audited, year-end financial statements for the latest fiscal year with the amounts in such financial statements; and

  (B) In connection with that procedure, no matters came to his attention which caused him to believe that the specified data should be adjusted.

  (4) The owner or operator may obtain an extension of the time allowed for submission of the documents specified in Subsection R315-265-145(e)(3) if the fiscal year of the owner or operator ends during the 90 days prior to the effective date of these regulations and if the year-end financial statements for that fiscal year will be audited by an independent certified public accountant. The extension will end no later than 90 days after the end of the owner's or operator's fiscal year. To obtain the extension, the owner's or operator's chief financial officer shall send, by the effective date of these regulations, a letter to the Director. This letter from the chief financial officer shall:

  (i) Request the extension;

  (ii) Certify that he has grounds to believe that the owner or operator meets the criteria of the financial test;

  (iii) Specify for each facility to be covered by the test the EPA Identification Number, name, address, and the current closure and post-closure cost estimates to be covered by the test;

  (iv) Specify the date ending the owner's or operator's latest complete fiscal year before the effective date of these regulations;

  (v) Specify the date, no later than 90 days after the end of such fiscal year, when he will submit the documents specified in Subsection R315-265-145(e)(3); and

  (vi) Certify that the year-end financial statements of the owner or operator for such fiscal year will be audited by an independent certified public accountant.

  (5) After the initial submission of items specified in Subsection R315-265-145(e)(3), the owner or operator shall send updated information to the Director within 90 days after the close of each succeeding fiscal year. This information must consist of all three items specified in Subsection R315-265-145(e)(3).

  (6) If the owner or operator no longer meets the requirements of Subsection R315-265-145 (e)(1), he shall send notice to the Director of intent to establish alternate financial assurance as specified in Section R315-265-145. The notice shall be sent by certified mail within 90 days after the end of the fiscal year for which the year-end financial data show that the owner or operator no longer meets the requirements. The owner or operator shall provide the alternate financial assurance within 120 days after the end of such fiscal year.

  (7) The Director may, based on a reasonable belief that the owner or operator may no longer meet the requirements of Subsection R315-265-145(e)(1), require reports of financial condition at any time from the owner or operator in addition to those specified in Subsection R315-265-145(e)(3). If the Director finds, on the basis of such reports or other information, that the owner or operator no longer meets the requirements of Subsection R315-265-145(e)(1), the owner or operator shall provide alternate financial assurance as specified in Section R315-265-145 within 30 days after notification of such a finding.

  (8) The Director may disallow use of this test on the basis of qualifications in the opinion expressed by the independent certified public accountant in his report on examination of the owner's or operator's financial statements, see Subsection R315-265-145(e)(3)(ii). An adverse opinion or a disclaimer of opinion will be cause for disallowance. The Director will evaluate other qualifications on an individual basis. The owner or operator shall provide alternate financial assurance as specified in Section R315-265-145 within 30 days after notification of the disallowance.

  (9) During the period of post-closure care, the Director may approve a decrease in the current post-closure cost estimate for which this test demonstrates financial assurance if the owner or operator demonstrates to the Director that the amount of the cost estimate exceeds the remaining cost of post-closure care.

  (10) The owner or operator is no longer required to submit the items specified in Subsection R315-265-145(e)(3) when:

  (i) An owner or operator substitutes alternate financial assurance as specified in Section R315-265-145; or

  (ii) The Director releases the owner or operator from the requirements of Section R315-265-145 in accordance with Subsection R315-265-145(h).

  (11) An owner or operator may meet the requirements of Section R315-265-145 by obtaining a written guarantee. The guarantor shall be the direct or higher-tier parent corporation of the owner or operator, a firm whose parent corporation is also the parent corporation of the owner or operator, or a firm with a "substantial business relationship" with the owner or operator. The guarantor shall meet the requirements for owners or operators in Subsections R315-265-145(e)(1) through (9) and shall comply with the terms of the guarantee. The wording of the guarantee shall be identical to the wording specified in Subsection R315-264-151(h). A certified copy of the guarantee shall accompany the items sent to the Director as specified in Subsection R315-265-145(e)(3). One of these items shall be the letter from the guarantor's chief financial officer. If the guarantor's parent corporation is also the parent corporation of the owner or operator, the letter shall describe the value received in consideration of the guarantee. If the guarantor is a firm with a "substantial business relationship" with the owner or operator, this letter shall describe this "substantial business relationship" and the value received in consideration of the guarantee. The terms of the guarantee must provide that:

  (i) If the owner or operator fails to perform post-closure care of a facility covered by the corporate guarantee in accordance with the post-closure plan and other interim status requirements whenever required to do so, the guarantor will do so or establish a trust fund as specified in Subsection R315-265-145(a) in the name of the owner or operator.

  (ii) The corporate guarantee will remain in force unless the guarantor sends notice of cancellation by certified mail to the owner or operator and to the Director. Cancellation may not occur, however, during the 120 days beginning on the date of receipt of the notice of cancellation by both the owner or operator and the Director, as evidenced by the return receipts.

  (iii) If the owner or operator fails to provide alternate financial assurance as specified in Section R315-265-145 and obtain the written approval of such alternate assurance from the Director within 90 days after receipt by both the owner or operator and the Director of a notice of cancellation of the corporate guarantee from the guarantor, the guarantor will provide such alternate financial assurance in the name of the owner or operator.

  (f) Use of multiple financial mechanisms. An owner or operator may satisfy the requirements of Section R315-265-145 by establishing more than one financial mechanism per facility. These mechanisms are limited to trust funds, surety bonds, letters of credit, and insurance. The mechanisms must be as specified in Subsections R315-265-145(a) through (d), respectively, of this section, except that it is the combination of mechanisms, rather than the single mechanism, which shall provide financial assurance for an amount at least equal to the current post-closure cost estimate. If an owner or operator uses a trust fund in combination with a surety bond or a letter of credit, he may use the trust fund as the standby trust fund for the other mechanisms. A single standby trust fund may be established for two or more mechanisms. The Director may use any or all of the mechanisms to provide for post-closure care of the facility.

  (g) Use of a financial mechanism for multiple facilities. An owner or operator may use a financial assurance mechanism specified in Section R315-265-145 to meet the requirements of Section R315-265-145 for more than one facility. Evidence of financial assurance submitted to the Director shall include a list showing, for each facility, the EPA Identification Number, name, address, and the amount of funds for post-closure care assured by the mechanism. The amount of funds available through the mechanism shall be no less than the sum of funds that would be available if a separate mechanism had been established and maintained for each facility. In directing funds available through the mechanism for post-closure care of any of the facilities covered by the mechanism, the Director may direct only the amount of funds designated for that facility, unless the owner or operator agrees to the use of additional funds available under the mechanism.

  (h) Release of the owner or operator from the requirements of Section R315-265-145. Within 60 days after receiving certifications from the owner or operator and a qualified Professional Engineer that the post-closure care period has been completed for a hazardous waste disposal unit in accordance with the approved plan, the Director will notify the owner or operator in writing that he is no longer required to maintain financial assurance for post-closure care of that unit, unless the Director has reason to believe that post-closure care has not been in accordance with the approved post-closure plan. The Director shall provide the owner or operator a detailed written statement of any such reason to believe that post-closure care has not been in accordance with the approved post-closure plan.
