(a) An owner or operator may satisfy the requirements of a fully funded trust or standby trust fund as provided in §37.201 of this title (relating to Trust Fund), except within 60 days following the executive director's final review and approval of closure or post closure expenditures for reimbursement, release of funds shall occur.
(b) An owner or operator may satisfy the requirements of a surety bond guaranteeing payment as provided in §37.211 of this title (relating to Surety Bond Guaranteeing Payment) except:
  (1) the surety must also be licensed in the State of Texas;
  (2) cancellation may not occur during the 90 days beginning on the date of receipt of the notice of cancellation; and
  (3) the bond must guarantee that the owner or operator will provide alternate financial assurance within 30 days after receipt of a notice of cancellation of the bond.
(c) An owner or operator may satisfy the requirements of an irrevocable standby letter of credit as provided in §37.231 of this title (relating to Irrevocable Standby Letter of Credit), except:
  (1) the letter of credit shall be automatically extended unless the issuer provides notice of cancellation at least 90 days before the current expiration date. Under the terms of the letter of credit, the 90 days shall begin on the date when both the owner or operator and the executive director have received the notice, as evidenced by the return receipts; and
  (2) in accordance with §37.231(h) of this title, the executive director shall draw on the letter of credit within 30 days after receipt of notice from the issuing institution that the letter of credit will not be extended, or within 60 days of an extension, if the owner or operator fails to establish and obtain approval of such alternate financial assurance from the executive director.
(d) A statement of intent may be used by a governmental entity subject to this subchapter. The statement of intent shall be subject to the executive director's approval and shall include the following:
  (1) a statement that funds will be made immediately available upon demand by the executive director;
  (2) the signature of an authorized official who has the authority to bind the governmental entity into a financial obligation, and has the authority to sign the statement of intent;
  (3) name of facility(ies), license number, and physical and mailing addresses; and
  (4) corresponding current cost estimates.
(e) An owner or operator may satisfy the requirements of financial assurance by establishing an external sinking fund as specified in this subsection. An external sinking fund has two components: a sinking fund account and a financial assurance mechanism such that the total of both equals, at all times, the current cost estimate. A sinking fund account is an account segregated from the owner's or operator's assets and is outside the owner's or operator's administrative control. As the value of the sinking fund account increases, the value of the second financial assurance mechanism decreases. When the external sinking fund account is equal to the current cost estimate, the second financial assurance mechanism will no longer be required to be maintained.
  (1) An external sinking fund account shall be approved by the executive director and administered by a third party that is regulated and examined by a federal or state agency.
  (2) The external sinking fund is established and maintained by setting aside funds periodically, at least annually.
(f) An owner or operator may satisfy the requirements of financial assurance by obtaining insurance that conforms to the requirements of this subsection, in addition to the requirements specified in Subchapters A and B of this chapter (relating to General Financial Assurance Requirements; and Financial Assurance Requirements for Closure, Post Closure, and Corrective Action), and submitting an originally-signed endorsement to the insurance policy to the executive director.
  (1) At a minimum, the insurer on the policy must be authorized to transact or be a surplus lines insurer eligible to engage in the business of insurance in Texas and have a minimum financial strength rating of "A" and a financial size category of "XV" as assigned by the A.M. Best Company.
  (2) The insurance policy must designate the commission as an additional insured.
  (3) The owner or operator must maintain the policy in full force and effect until the executive director consents to termination of the policy. Failure to pay the premium, without substitution of alternate financial assurance as specified in this subchapter, shall constitute a violation of these regulations, warranting such remedy as the executive director deems necessary. Such violation shall be deemed to begin upon receipt by the executive 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 of the policy.
  (4) The policy must 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 shall, 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 executive director. Cancellation, termination, or failure to renew may not occur, however, during 120 days beginning with the date of receipt of the notice by both the executive director and the owner or operator, as evidenced by the return receipts. The policy must also provide that the insurer shall pay the face amount of the insurance policy to the State of Texas for deposit as specified under §37.9045(a)(6) of this title (relating to Financial Assurance Requirements for Closure, Post Closure, and Corrective Action), if the executive director does not approve acceptable replacement financial assurance within 90 days of receiving notice by certified mail from the insurer of its election to cancel, terminate, or not renew the policy.
  (5) The insurance policy may not contain an exclusion for intentional, willful, knowing, or deliberate noncompliance with a statute, regulation, order, notice, or government instruction.
  (6) The wording of the endorsement to the insurance policy must be identical to the wording specified in §37.9052 of this title (relating to Endorsement).
  (7) The insurance policy must be issued for a face amount at least equal to the current cost estimate for closure, post closure, or corrective action, except when a combination of mechanisms are used in accordance with §37.41 of this title (relating to Use of Multiple Financial Assurance Mechanisms). Actual payments by the insurer shall not change the face amount, although the insurer's future liability shall be lowered by the amount of the payments.
  (8) The insurance policy must guarantee that funds shall be available to provide for closure, post closure, or corrective action of the facility. The policy shall also guarantee that once closure, post closure, or corrective action begins, the issuer shall be responsible for paying out funds, up to an amount equal to the face amount of the policy, upon the direction of the executive director, to such party or parties as the executive director specifies.
  (9) An owner or operator or any other person authorized to perform closure, post closure, or corrective action may request reimbursement for closure, post closure, or corrective action expenditures by submitting itemized bills to the executive director. The request shall include an explanation of the expenses and all applicable itemized bills. The owner or operator may request reimbursement for partial closure only if the remaining value of the policy is sufficient to cover the maximum costs of closing the facility over its remaining operating life. Within 60 days after receiving bills for closure, post closure, or corrective action activities, the executive director shall determine whether the closure, post closure, or corrective action expenditures are in accordance with the approved closure, post closure, or corrective action activities or are otherwise justified and, if so, shall instruct the insurer to make reimbursement in such amounts as the executive director specifies in writing. If the executive director has reason to believe that the maximum cost of closure, post closure, or corrective action over the remaining life of the facility will be greater than the face amount of the policy, the executive director may withhold reimbursement of such amounts as deemed prudent until the executive director determines, in accordance with Subchapters A and B of this chapter, that the owner or operator is no longer required to maintain financial assurance requirements for closure, post closure, or corrective action of the facility. If the executive director does not instruct the insurer to make such reimbursements, the executive director shall provide the owner or operator with a detailed written statement of Cont'd...
