Wis. Admin. Code Department of Natural Resources NR 664.0143

Current through November 25, 2024
Section NR 664.0143 - Financial assurance for closure

An owner or operator of each facility shall establish financial assurance for closure of the facility. The owner or operator shall choose from the options as specified in subs. (1) to (8).

(1) CLOSURE TRUST FUND.
(a) An owner or operator may satisfy the requirements of this section by establishing a closure trust fund which conforms to the requirements of this subsection and submitting an originally signed duplicate of the trust agreement to the department. An owner or operator of a new facility shall submit the originally signed duplicate of the trust agreement to the department at least 60 days before the date on which hazardous waste is first received for treatment, storage or disposal. 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 state agency.
(b) The wording of the trust agreement shall be identical to the wording on the department form specified in s. NR 664.0151(1) (a) and the trust agreement shall be accompanied by a formal certification of acknowledgment as specified in s. NR 664.0151(1) (b). Schedule A of the trust agreement shall be updated within 60 days after a change in the amount of the current closure cost estimate covered by the agreement.
(c) Payments into the trust fund shall be made annually by the owner or operator over the term of the initial license or over the remaining operating life of the facility as estimated in the closure plan, whichever period is shorter. For the purposes of this section, this period is referred to as the "pay-in period." The payments into the closure trust fund shall be made as follows:
1. For a new facility, the first payment shall be made before the initial receipt of hazardous waste for treatment, storage or disposal. A receipt from the trustee for this payment shall be submitted by the owner or operator to the department before this initial receipt of hazardous waste. The first payment shall be at least equal to the current closure cost estimate, except as provided in sub. (9), divided by the number of years in the pay-in period. Subsequent payments shall be made no later than 30 days after each anniversary date of the first payment. The amount of each subsequent payment shall be determined by this formula:

where CE is the current 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.

2. If an owner or operator establishes a trust fund as specified in this subsection, and the value of that trust fund is less than the current closure cost estimate when a license is awarded for the facility, the amount of the current closure cost estimate still to be paid into the trust fund shall be paid in over the pay-in period as defined in par. (c)(intro). Payments shall continue to be made no later than 30 days after each anniversary date of the first payment made pursuant to ch. NR 665. The amount of each payment shall be determined by this formula:

where CE is the current 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.

(d) The owner or operator may accelerate payments into the trust fund or may deposit the full amount of the current closure cost estimate at the time the fund is established. However, the owner or operator 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 par. (c).
(e) If the owner or operator establishes a closure trust fund after having used one or more alternate mechanisms specified in this section or in s. NR 665.0143, the 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 according to specifications of this subsection and s. NR 665.0143(1), as applicable.
(f) After the pay-in period is completed, whenever the current closure cost estimate changes, 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 closure cost estimate, or obtain other financial assurance as specified in this section to cover the difference.
(g) If the value of the trust fund is greater than the total amount of the current closure cost estimate, the owner or operator may submit a written request to the department for release of the amount in excess of the current closure cost estimate.
(h) If an owner or operator substitutes other financial assurance as specified in this section for all or part of the trust fund, the owner or operator may submit a written request to the department for release of the amount in excess of the current closure cost estimate covered by the trust fund.
(i) Within 60 days after receiving a request from the owner or operator for release of funds as specified in par. (g) or (h), the department will instruct the trustee to release to the owner or operator funds as the department specifies in writing.
(j) After beginning partial or final closure, an owner or operator or another person authorized to conduct partial or final closure may request reimbursements for partial or final closure expenditures by submitting itemized bills to the department. The owner or operator may request reimbursements for partial closure only if sufficient funds are remaining in the trust fund to cover the maximum costs of closing the facility over its remaining operating life. Within 60 days after receiving bills for partial or final closure activities, the department will instruct the trustee to make reimbursements in those amounts as the department specifies in writing, if the department determines that the partial or final closure expenditures are in accordance with the approved closure plan, or otherwise justified. If the department has reason to believe that the maximum cost of closure over the remaining life of the facility will be significantly greater than the value of the trust fund, the department may withhold reimbursements of amounts as the department deems prudent until the department determines, in accordance with sub. (11) that the owner or operator is no longer required to maintain financial assurance for final closure of the facility. If the department does not instruct the trustee to make the reimbursements, the department will provide the owner or operator with a detailed written statement of reasons.
(k) The department will agree to termination of the trust when one of the following applies:
1. An owner or operator substitutes alternate financial assurance as specified in this section.
2. The department releases the owner or operator from the requirements of this section in accordance with sub. (11).
(2) SURETY BOND GUARANTEEING PAYMENT INTO A CLOSURE TRUST FUND.
(a) An owner or operator may satisfy the requirements of this section by obtaining a surety bond which conforms to the requirements of this subsection and submitting the bond to the department. An owner or operator of a new facility shall submit the bond to the department at least 60 days before the date on which hazardous waste is first received for treatment, storage or disposal. The bond shall be effective before this initial receipt of hazardous waste. The surety company issuing the bond shall, at a minimum, be among those listed as acceptable sureties on federal bonds in Circular 570 of the U.S. department of the treasury.
(b) The wording of the surety bond shall be identical to the wording on the department form specified in s. NR 664.0151(2).
(c) 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 shall be deposited by the surety directly into the standby trust fund in accordance with instructions from the department. This standby trust fund must meet the requirements specified in sub. (1) except for all of the following:
1. An originally signed duplicate of the trust agreement must be submitted to the department with the surety bond.
2. Until the standby trust fund is funded pursuant to the requirements of this section, all of the following are not required:
a. Payments into the trust fund as specified in sub. (1).
b. Updating of Schedule A of the trust agreement (see Form 4430-022) to show current closure cost estimates.
c. Annual valuations as required by the trust agreement.
d. Notices of nonpayment as required by the trust agreement.
(d) The bond must guarantee that the owner or operator shall do any of the following:
1. 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.
2. 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 department becomes final or within 15 days after an order to begin final closure is issued.
3. Provide alternate financial assurance as specified in this section, and obtain the department's written approval of the assurance provided, within 90 days after receipt by both the owner or operator and the department of a notice of cancellation of the bond from the surety.
(e) 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.
(f) The penal sum of the bond shall be in an amount at least equal to the current closure cost estimate, except as provided in sub. (9).
(g) Whenever the current closure cost estimate increases to an amount greater then 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 closure cost estimate and submit evidence of the increase to the department, or obtain other financial assurance as specified in this section to cover the increase. Whenever the current closure cost estimate decreases, the penal sum may be reduced to the amount of the current closure cost estimate following written approval by the department.
(h) 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 department. 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 department, as evidence by the return receipts. Not less than 30 days prior to the expiration of the 120 day notice period, the owner shall deliver to the department a replacement bond or other proof of financial responsibility under this section, in the absence of which all storage, treatment or disposal operations shall immediately cease and the bond shall remain in effect as long as any obligation of the owner remains for closure.
(i) The owner or operator may cancel the bond if the department has given prior written consent based on the department's receipt of evidence of alternate financial assurance as specified in this section.
(3) SURETY BOND GUARANTEEING PERFORMANCE OF CLOSURE.
(a) An owner or operator may satisfy the requirements of this section by obtaining a surety bond which conforms to the requirements of this subsection and submitting the bond to the department. An owner or operator of a new facility shall submit the bond to the department at least 60 days before the date on which hazardous waste is first received for treatment, storage or disposal. The bond shall be effective before this initial receipt of hazardous waste. The surety company issuing the bond shall, at a minimum, be among those listed as acceptable sureties on federal bonds in Circular 570 of the U.S. department of the treasury.
(b) The wording of the surety bond shall be identical to the wording on the department form specified in s. NR 664.0151(3).
(d) The bond shall guarantee that the owner or operator will do one of the following:
1. Perform final closure in accordance with the closure plan and other requirements of the license for the facility whenever required to do so.
2. Provide alternate financial assurance as specified in this section, and obtain the department's written approval of the assurance provided, within 90 days after receipt by both the owner or operator and the department of a notice of cancellation of the bond from the surety.
(e) 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. Following a determination by the department or EPA pursuant to 42 USC 6928 that the owner or operator has failed to perform final closure in accordance with the approved closure plan and other license requirements when required to do so, under the terms of the bond the surety will perform final closure as guaranteed by the bond or shall pay the penal sum of the bond to the department.
(f) The penal sum of the bond shall be in an amount at least equal to the current closure cost estimate.
(g) Whenever the current 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 closure cost estimate and submit evidence of the increase to the department, or obtain other financial assurance as specified in this section. Whenever the current closure cost estimate decreases, the penal sum may be reduced to the amount of the current closure cost estimate following written approval by the department.
(h) 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 department. 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 department, as evidenced by the return receipts. Not less than 30 days prior to the expiration of the 120-day notice period, the owner shall deliver to the department a replacement bond or other proof of financial responsibility under this section, in the absence of which all storage, treatment or disposal operations shall immediately cease and the bond shall remain in effect as long as any obligation of the owner remains for closure.
(i) The owner or operator may cancel the bond if the department has given prior written consent. The department will provide written consent when any of the following apply:
1. An owner or operator substitutes alternate financial assurance as specified in this section.
2. The department releases the owner or operator from the requirements of this section in accordance with sub. (11).
(j) The surety will not be liable for deficiencies in the performance of closure by the owner or operator after the department releases the owner or operator from the requirements of this section in accordance with sub. (11).
(4) CLOSURE LETTER OF CREDIT .
(a) An owner or operator may satisfy the requirements of this section by obtaining an irrevocable letter of credit which conforms to the requirements of this subsection and submitting the letter to the department. An owner or operator of a new facility shall submit the letter of credit to the department at least 60 days before the date on which hazardous waste is first received for treatment, storage or disposal. The letter of credit shall be effective before this initial receipt of hazardous waste. 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 state agency.
(b) The wording of the letter of credit shall be identical to the wording on the department form specified in s. NR 664.0151(4).
(d) 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 closure of the facility by the letter of credit.
(e) 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 department 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 department have received the notice, as evidenced by the return receipts.
(f) The letter of credit shall be issued in an amount at least equal to the current closure cost estimate, except as provided in sub. (9).
(g) Whenever the current closure cost estimate increases to an amount greater than the amount of the credit, 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 closure cost estimate and submit evidence of the increase to the department, or obtain other financial assurance as specified in this section to cover the increase. Whenever the current closure cost estimate decreases, the amount of the credit may be reduced to the amount of the current closure cost estimate following written approval by the department.
(h) Following a determination by the department or EPA pursuant to 42 USC 6928 that the owner or operator has failed to perform final closure in accordance with the closure plan and other license requirements when required to do so, the department may draw on the letter of credit.
(i) If the owner or operator does not establish alternate financial assurance as specified in this section and obtain written approval of the alternate assurance from the department within 90 days after receipt by both the owner or operator and the department of a notice from issuing institution that it has decided not to extend the letter of credit beyond the current expiration date, the department will draw on the letter of credit. The department may delay the drawing if the issuing institution grants an extension of the term of the credit. During the last 30 days of any extension the department will draw on the letter of credit if the owner or operator has failed to provide alternate financial assurance as specified in this section and obtain written approval of the assurance from the department.
(j) The department will authorize the release of the letter of credit when any of the following apply:
1. An owner or operator substitutes alternate financial assurance as specified in this section.
2. The department releases the owner or operator from the requirements of this section in accordance with sub. (11).
(5) CLOSURE INSURANCE.
(a) An owner or operator may satisfy the requirements of this section by obtaining closure insurance which conforms to the requirements of this subsection and submitting a certificate of the insurance to the department. An owner or operator of a new facility shall submit the certificate of insurance to the department at least 60 days before the date on which hazardous waste is first received for treatment, storage or disposal. The insurance shall be effective before this initial receipt of hazardous waste. 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. The department, after conferring with the Wisconsin insurance commissioner, shall determine the acceptability of a surplus lines or captive insurance company to provide coverage for proof of financial responsibility. The department shall ask the insurance commissioner to provide a financial analysis of the insurer including a recommendation as to the insurer's ability to provide the required coverage. The department may require a periodic review of the acceptability of a surplus lines or captive insurance company.
(b) The wording of the certificate of insurance shall be identical to the wording on the department form specified in s. NR 664.0151(5).
(c) The closure insurance policy shall be issued for a face amount at least equal to the current closure cost estimate, except as provided in sub. (9). 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.
(d) The closure insurance policy shall guarantee that funds will be available to close the facility whenever final closure occurs. The policy shall also guarantee that once final closure 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 department, to the party or parties as the department specifies.
(e) After beginning partial or final closure, an owner or operator or any other person authorized to conduct closure may request reimbursements for closure expenditures by submitting itemized bills to the department. The owner or operator may request reimbursements 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 activities, the department will instruct the insurer to make reimbursements in the amounts as the department specifies in writing, if the department determines that the partial or final closure expenditures are in accordance with the approved closure plan or otherwise justified. If the department has reason to believe that the maximum cost of closure over the remaining life of the facility will be significantly greater than the face amount of the policy, the department may withhold reimbursements of the amounts as the department deems prudent until the department determines, in accordance with sub. (11), that the owner or operator is no longer required to maintain financial assurance for final closure of the facility. If the department does not instruct the insurer to make the reimbursements, the department will provide the owner or operator with a detailed written statement of reasons.
(f) The owner or operator shall maintain the policy in full force and effect until the department consents to termination of the policy by the owner or operator as specified in par. (j). Failure to pay the premium, without substitution of alternate financial assurance as specified in this section, will constitute a significant violation of this chapter, warranting a remedy as the department deems necessary. The violation will be deemed to begin upon receipt by the department of a notice of future cancellation, termination or failure to renew due to nonpayment of the premium, rather than upon the date of expiration.
(g) Each policy shall contain a provision allowing assignment of the policy to a successor owner or operator. The assignment may be conditional upon consent of the insurer, provided the consent is not unreasonably refused.
(h) The policy shall provide that the insurer may not cancel, terminate or fail to renew the policy unless a replacement insurance policy or other proof of financial responsibility under this section is provided to the department by the owner or operator. 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 the insurer elects to cancel, terminate or fail to renew the policy, the insurer shall provide notice by certified mail to the owner or operator and the department not less than 120 days prior to the proposed cancellation date. 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 department 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 any of the following apply:
1. The department deems the facility abandoned.
2. The license is denied, suspended or revoked or a new license is denied.
3. Closure is ordered by the department or a U.S. district court or other court of competent jurisdiction.
4. The owner or operator is named as debtor in a voluntary or involuntary bankruptcy proceeding under 11 USC.
5. The premium due is paid.
(i) Whenever the current closure cost estimate increases to an amount greater than the face amount of the policy, 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 closure cost estimate and submit evidence of the increase to the department, or obtain other financial assurance as specified in this section to cover the increase. Whenever the current closure cost estimate decreases, the face amount may be reduced to the amount of the current closure cost estimate following written approval by the department.
(j) The department will give written consent to the owner or operator that the owner or operator may terminate the insurance policy when any of the following apply:
1. An owner or operator substitutes alternate financial assurance as specified in this section.
2. The department releases the owner or operator from the requirements of this section in accordance with sub. (11).
(6) NET WORTH TEST FOR CLOSURE.
(a) An owner or operator of a disposal facility may use the net worth test to provide financial responsibility if all of the following are met:
1. Only a company that meets the definition in s. 289.41(1) (b), Stats., may use the net worth method of providing proof of financial responsibility.
2. The owner or operator shall comply with the net worth test requirements of s. 289.41(4), (6) and (7), Stats., and the minimum security requirements of s. 289.41(9), Stats., whichever are applicable. The updated net worth test information required under s. 289.41(4), Stats., shall be submitted annually to the department within 90 days after the close of the company's fiscal year.
(b) For companies with more than one facility, the total cost of compliance for all facilities shall be used to determine the net worth to closure and long-term care cost ratio.
(7) CLOSURE DEPOSIT WITH THE DEPARTMENT. An owner may deposit cash, certificates of deposit or U.S. government securities with the department. The deposit must be accompanied by a signed duplicate original of Form 4430-028 as specified in s. NR 664.0151(14). The amount of the deposit shall be determined according to s. NR 664.0142. Cash deposits placed with the department shall be segregated and invested in an interest bearing account. All interest payments shall be accumulated in the account. The department shall have the right to use part or all of the funds to carry out the closure requirements of the approved closure plan or the applicable requirements in s. NR 664.0112 if the owner fails to do so.
(8) CLOSURE ESCROW ACCOUNT.
(a) An owner or operator may satisfy the requirements of this section by establishing a closure escrow account which conforms to the requirements of this subsection and submitting an originally signed duplicate of the escrow agreement to the department. An owner or operator of a new facility shall submit the originally signed duplicate of the escrow agreement to the department at least 60 days before the date on which hazardous waste is first received for treatment, storage or disposal. The escrow agent shall be an entity which has the authority to act as an escrow agent, and the escrow account shall be established with a bank or financial institution which is examined and regulated by the state or a federal agency.
(b) The wording of the escrow agreement shall be identical to the wording on the department form specified in s. NR 664.0151(6) (a), and the escrow agreement shall be accompanied by a formal certification of acknowledgment as specified in s. NR 664.0151(6) (b). Schedule A of the escrow agreement shall be updated within 60 days after a change in the amount of the current closure cost estimate covered by the agreement.
(c) Payments into the escrow account shall be made annually by the owner or operator over the term of the initial license or over the remaining operating life of the facility as estimated in the closure plan, whichever period is shorter. For the purposes of this section, this period is referred to as the "pay-in period." The payments into the closure escrow account shall be made as follows:
1. For a new facility, the first payment shall be made before the initial receipt of hazardous waste for treatment, storage or disposal. A receipt from the escrow agent for this payment shall be submitted by the owner or operator to the department before this initial receipt of hazardous waste. The first payment shall be at least equal to the current closure cost estimate, except as provided in sub. (9), divided by the number of years in the pay-in period. Subsequent payments shall be made no later than 30 days after each anniversary date of the first payment. The amount of each subsequent payment shall be determined by this formula:

View Image

where CE is the current closure cost estimate, CV is the current value of the escrow account and Y is the number of years remaining in the pay-in period.

2. If an owner or operator establishes a escrow account as specified in this subsection, and the value of that escrow account is less than the current closure cost estimate when a license is awarded for the facility, the amount of the current closure cost estimate still to be paid into the escrow account shall be paid in over the pay-in period as defined in the introduction to this paragraph. Payments shall continue to be made no later than 30 days after each anniversary date of the first payment made pursuant to ch. NR 665. The amount of each payment shall be determined by this formula:

View Image

where CE is the current closure cost estimate, CV is the current value of the escrow account and Y is the number of years remaining in the pay-in period.

(d) The owner or operator may accelerate payments into the escrow account or may deposit the full amount of the current closure cost estimate at the time the account is established. However, the owner or operator shall maintain the value of the account at no less than the value that the account would have if annual payments were made as specified in par. (c).
(e) If the owner or operator establishes a closure escrow account after having used one or more alternate mechanisms specified in this section or in s. NR 665.0143, the first payment shall be in at least the amount that the account would contain if the escrow account were established initially and annual payments were made according to the specifications of this subsection and s. NR 665.0143(7), as applicable.
(f) After the pay-in period is completed, whenever the current closure cost estimate changes, the owner or operator shall compare the new estimate with the escrow agent's most recent annual valuation of the escrow account. If the value of the account 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 account so that its value after this deposit at least equals the amount of the current closure cost estimate, or obtain other financial assurance as specified in this section to cover the difference.
(g) If the value of the escrow account is greater than the total amount of the current closure cost estimate, the owner or operator may submit a written request to the department for release of the amount in excess of the current closure cost estimate.
(h) If an owner or operator substitutes other financial assurance as specified in this section for all or part of the escrow account, the owner or operator may submit a written request to the department for release of the amount in excess of the current closure cost estimate covered by the escrow account.
(i) Within 60 days after receiving a request from the owner or operator for release of funds as specified in par. (g) or (h), the department will instruct the escrow agent to release to the owner or operator funds as the department specifies in writing.
(j) After beginning partial or final closure, an owner or operator or another person authorized to conduct partial or final closure may request reimbursements for partial or final closure expenditures by submitting itemized bills to the department. The owner or operator may request reimbursements for partial closure only if sufficient funds are remaining in the escrow account to cover the maximum costs of closing the facility over its remaining operating life. Within 60 days after receiving bills for partial or final closure activities, the department will instruct the escrow agent to make reimbursements in those amounts as the department specifies in writing, if the department determines that the partial or final closure expenditures are in accordance with the approved closure plan, or otherwise justified. If the department has reason to believe that the maximum cost of closure over the remaining life of the facility will be significantly greater than the value of the escrow account, the department may withhold reimbursements of amounts as the department deems prudent until the department determines, in accordance with sub. (11) that the owner or operator is no longer required to maintain financial assurance for final closure of the facility. If the department does not instruct the escrow agent to make the reimbursements, the department will provide the owner or operator with a detailed written statement of reasons.
(k) The department will agree to termination of the escrow account when one of the following applies:
1. An owner or operator substitutes alternate financial assurance as specified in this section.
2. The department releases the owner or operator from the requirements of this section in accordance with sub. (11).
(9) USE OF MULTIPLE FINANCIAL MECHANISMS. An owner or operator may satisfy the requirements of this section by establishing more than one financial mechanism per facility. These mechanisms are limited to trust funds, deposits with the department, surety bonds guaranteeing payment, escrow accounts, letters of credit and insurance. The mechanisms shall be as specified in subs. (1), (2), (4), (5), (7) and (8), 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 closure cost estimate. The department may use any or all of the mechanisms to provide for closure of the facility.
(10) USE OF A FINANCIAL MECHANISM FOR MULTIPLE FACILITIES. An owner or operator may use a financial assurance mechanism specified in this section to meet the requirements of this section for more than one facility. Evidence of financial assurance submitted to the department shall include a list showing, for each facility, the EPA identification number, name, address and the amount of funds for closure assured by the mechanism. If the facilities covered by the mechanism are in more than one state, identical evidence of financial assurance shall be submitted to and maintained with the state agency regulating hazardous waste or with the appropriate U.S. EPA regional administrator if the facility is located in unauthorized states. 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 closure of any of the facilities covered by the mechanism, the department 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.
(11) RELEASE OF THE OWNER OR OPERATOR FROM THE REQUIREMENTS OF THIS SECTION. Within 60 days after receiving certifications from the owner or operator and a qualified professional engineer that final closure has been completed in accordance with the approved closure plan, the department will notify the owner or operator in writing that the owner or operator is no longer required by this section to maintain financial assurance for final closure of the facility, unless the department has reason to believe that final closure has not been in accordance with the approved closure plan. The department shall provide the owner or operator a detailed written statement of any reason to believe that closure has not been in accordance with the approved closure plan.
