Chapter 4 Class 1 Landfills

Rule 22.401 - Location Restrictions

(a) Responsibilities - Applicants for a permit for a Class 1 landfill shall be responsible for selection of the proposed site subject to the provisions of this section. Solid waste disposal facilities or practices which violate any of the following criteria pose a reasonable probability of adverse effects on health or the environment.

Rule 22.402 - Airport Safety

(a) Location Prohibition for New Facilities - New permitted Class 1 landfills shall not be located within 10,000 feet (3,048 meters) of any airport runway end used by turbojet aircraft or within 5,000 feet (1,524 meters) of any airport runway end used by only piston-type aircraft.

(b) Demonstration for Existing Class 1 Landfills - Existing Class 1 landfills, existing units and lateral expansions that are located within the distances specified in paragraph (a) must demonstrate that the units are designed and operated so that the municipal solid waste landfill unit does not pose a bird hazard to aircraft. Existing Class 1 landfills and existing units shall make the demonstration not later than the compliance dates specified in Rule 22.103(f) and submit the demonstration to the Director for approval. Lateral expansions shall make the demonstration prior to construction.

(c) FAA Notification - Owners or operators proposing to site new Class 1 municipal solid waste landfill units and lateral expansions within a five-mile radius of any airport runway end used by turbojet or piston-type aircraft must notify the affected airport and the Federal Aviation Administration (FAA) and furnish proof of notification to the Director.

A prohibition on locating a new municipal solid waste landfill near certain airports was enacted in Section 503 of the Wendell H. Ford Aviation Investment and Reform Act for the 21st Century (Ford Act), Pub. L. 106-181 (49 U.S.C. 44718 note). Section 503 prohibits the "construction or establishment" of new municipal solid waste landfills after April 5, 2000 within six miles of certain smaller public airports. The Federal Aviation Administration (FAA) administers the Ford Act and has issued guidance in FAA Advisory Circular 150/5200-34, dated August 26, 2000. Owners or operators proposing to locate new Class 1 municipal solid waste landfill units within a six-mile radius of any airport runway end must furnish to the Director proof of approval from the Federal Aviation Administration (FAA) for the new Class 1 municipal solid waste landfill unit or units.

According to the guidance, no person shall construct or establish a new municipal solid waste landfill that receives putrescible waste within six miles of a public airport that has received grants under chapter 471 and is primarily served by general aviation aircraft and regularly scheduled flights of aircraft designed for 60 passengers or less unless the State aviation agency requests that the Administrator of the Federal Aviation Administration exempt the landfill from the application of this subsection and the Administrator determines that such exemption would have no adverse impact on aviation safety.

The limitations of § 44718(d), as amended, only apply to a new municipal solid waste landfill (constructed or established after April 5, 2000). The statutory limitations are not applicable where construction or establishment of a municipal solid waste landfill began on or before April 5, 2000, or to an existing municipal solid waste landfill (received putrescible waste on or before April 5, 2000). Further, an existing municipal solid waste landfill that is expanded or modified after April 5, 2000, would not be held to the limitations of § 44718(d), as amended.

Rule 22.403 - Floodplains

(a) Applicability - Owners or operators of new Class 1 landfill units, existing units, and lateral expansions located in 100-year floodplains must demonstrate that the unit will not restrict the flow of the base flood, reduce the temporary water storage capacity of the floodplain, or result in washout of solid waste so as to pose a hazard to human health and the environment.

(b) Effective Date - The owner or operator of existing Class 1 landfills must place the demonstration in the operating record and submit the demonstration to the Director not later than the compliance date in Rule 22.103(f).

Rule 22.404 - Wetlands

(a) Applicability - New Class 1 municipal solid waste landfill units and lateral expansions, and other facilities identified in these rules, shall not be located in wetlands, unless the owner or operator can make the following demonstrations to the Director.

(2) The construction and operation of the unit will not:

(i) Cause or contribute to violations of any applicable State water quality standard,

(ii) Violate any applicable toxic effluent standard or prohibition under Section 307 of the Clean Water Act,

(iii) Jeopardize the continued existence of endangered or threatened species or result in the destruction or adverse modification of a critical habitat, protected under the Endangered Species Act of 1973, and

(iv) Violate any requirement under the Marine Protection, Research, and Sanctuaries Act of 1972 for the protection of a marine sanctuary;

(3) The unit will not cause or contribute to significant degradation of wetlands. The owner or operator must demonstrate the integrity of the unit and its ability to protect ecological resources by addressing the following factors:

(i) Erosion, stability, and migration potential of native wetland soils, muds and deposits used to support the unit;

(ii) Erosion, stability, and migration potential of dredged and fill materials used to support the unit;

(iii) The volume and chemical nature of the waste managed in the unit;

(iv) Impacts on fish, wildlife, and other aquatic resources and their habitat from release of the solid waste;

(v) The potential effects of catastrophic release of waste to the wetland and the resulting impacts on the environment; and

(vi) Any additional factors, as necessary, to demonstrate that ecological resources in the wetland are sufficiently protected.

(4) To the extent required under Section 404 of the Clean Water Act or applicable State wetlands laws, steps have been taken to attempt to achieve no net loss of wetlands (as defined by acreage and function) by first avoiding impacts to wetlands to the maximum extent practicable as required by paragraph (a)(1) of this section, then minimizing unavoidable impacts to the maximum extent practicable, and finally offsetting remaining unavoidable wetland impacts through all appropriate and practicable compensatory mitigation actions (e.g., restoration of existing degraded wetlands or creation of man-made wetlands); and

(5) Sufficient information is available to make a reasonable determination with respect to these demonstrations.

(b) Class 1 Effective Date - New Class 1 municipal solid waste landfill units and lateral expansions shall meet all of the requirements of this section and shall demonstrate to the Director that the facility is not located in a wetland, or make the demonstration required in paragraph (a) prior to permitting of the new unit or lateral expansion of an existing unit.

The method must include estimation and testing of the contrasts between each compliance well's mean and the background mean levels for each constituent.

(2) An analysis of variance (ANOVA) based on ranks followed by multiple comparisons procedures to identify statistically significant evidence of contamination. The method must include estimation and testing of the contrasts between each compliance well's median and the background median levels for each constituent.

(3) A tolerance or prediction interval procedure in which an interval for each constituent is established from the distribution of the background data, and the level of each constituent in each compliance well is compared to the upper tolerance or prediction limit.

(4) A control chart approach that gives control limits for each constituent.

(5) Another statistical test method that meets the performance standards of Rule 22.1203(h). The owner or operator must place a justification for this alternative in the operating record and notify the Director of the use of this alternative test. The justification must demonstrate that the alternative method meets the performance standards of Rule 22.1203(h).

(h) Statistical Method Selection Criteria - Any statistical method chosen under Rule 22.1203(g) shall comply with the following performance standards, as appropriate:

(1) The statistical method used to evaluate ground water monitoring data shall be appropriate for the distribution of chemical parameters or hazardous constituents. If the distribution of the chemical parameters or hazardous constituents is shown by the owner or operator to be inappropriate for a normal theory test, then the data should be transformed or a distribution-free theory test should be used. If the distributions for the constituents differ, more than one statistical method may be needed.

(2) If an individual well comparison procedure is used to compare an individual compliance well constituent concentration with background constituent concentrations or a ground water protection standard, the test shall be done at a Type I error level no less than 0.01 for each testing period. If a multiple comparisons procedure is used, the Type I experiment wise error rate for each testing period shall be no less than 0.05; however, the Type I error of no less than 0.01 for individual well comparisons must be maintained. This performance standard does not apply to tolerance intervals, prediction intervals, or control charts.

(3) If a control chart approach is used to evaluate ground water monitoring data, the specific type of control chart and its associated parameter values shall be protective of human health and the environment. The parameters shall be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.

(4) If a tolerance interval or a prediction interval is used to evaluate ground water monitoring data, the levels of confidence and, for tolerance intervals, the percentage of the population that the interval must contain, shall be protective of human health and the environment. These parameters shall be determined after considering the number of samples in the background data base, the data distribution, and the range of the concentration values for each constituent of concern.

(5) The statistical method shall account for data below the limit of detection [i.e., the method detection limit (MDL) as specified in Rule 22.1204(d) of this part] with one or more statistical procedures that are protective of human health and the environment. A facility should report values between the Method Detection Limit (MDL) and Practical Quantitation Limit (PQL) but only utilize values reported above the PQL in the statistics. Any PQL or MDL that is used in the statistical method shall be the lowest concentration level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions using current laboratory standards. All verifiable, positive detections above the constituent practical quantitation limit (PQL) must be reported and included in the statistical analysis.

(6) If necessary, the statistical method shall include procedures to control or correct for seasonal and spatial variability as well as temporal correlation in the data.

(i) Determination of Statistically Significant Increase or Decrease- The owner or operator must determine whether or not there is a statistically significant increase or decreaseover background values for pH. The owner or operator must determine whether or not there is a statistically significant increase for each parameter or constituent required in the particular ground water monitoring program that applies to the landfill, as determined under Rule 22.1204(a) or Rule 22.1205(a).

(1) In determining whether a statistically significant increase has occurred, the owner or operator must compare the ground water quality of each parameter or constituent at each monitoring well designated pursuant to Rule 22.1202(a)(2) to the background value of that constituent, according to the statistical procedures and performance standards specified under paragraphs (g) and (h) of this section.

(2) Within a reasonable period of time after completing sampling and analysis, the owner or operator must determine whether there has been a statistically significant increase compaired to the background at each monitoring well. The owner or operator shall notify the Division in writing of statistically significant increases in detection monitoring water chemistry parameters.

For data quality assurance purposes, the statistical evaluation should be performed by a third party independent from the contract laboratory analyzing the ground water;

(6) Division notification procedures in the event that statistically significant increases in analytes are noted;

(7) A contingency plan must be developed which outlines the procedures to initiate an assessment monitoring program once confirmed statistically significant increases in analyte concentrations have been detected and the Solid Waste Division has been notified;

(k) Ground Water Monitor Reporting - The owner or operator of a Class 1 or 3 facility shall submit to the Director a Ground Water Monitoring Report prepared and certified by a qualified ground water scientist which contains a determination of the direction of ground water flow across the site based on water level measurements taken during the most recent sampling event at the facility and potentiometric surface map showing the locations of the monitor wells at the site. The permittee shall also provide a determination of the rate of ground water flow across the site. The facility must in accordance with the approved Sampling and Analysis Plan (SAP) determine if a Statistically Significant Increase has occurred for any constituent detected above established background concentrations at the facility, based on the analytical results from the most recent sampling event. The facility must provide appropriate documentation of SSI's in the GWMR. The operator shall analyze the monitoring data collected and provide a discussion in the GWMR on the findings and conclusions concerning ground water quality at the facility.

(a) Landfill Cover Design - This section applies to all Class 1 landfills that accepted wastes after October 9, 1991 and to all other Class 1, Class 3, and Class 4 landfill units in operation after May 7, 1995. Owners or operators of all landfill units must install a final cover system that is designed to minimize infiltration and erosion. The final cover system must be comprised of an erosion layer underlain by an infiltration layer as follows:

(1) The infiltration layer must be comprised of a minimum of 18 inches of earthen material that has a permeability less than or equal to the permeability of any bottom liner system or natural subsoils present, or a permeability no greater than 1 x 10-5 cm/sec, whichever is less. To meet this requirement, a flexible membrane liner shall be incorporated into the final cover design where the bottom liner design includes a composite liner, and

(2) The erosion layer must consist of a minimum 6 inches of earthen material that is capable of sustaining native plant growth.

The final cover system requirements specified above are in addition to any daily or intermediate cover required by this rule, or any drainage or gas collection layers necessary for proper performance of the cover system.

(b) Alternative Final Cover Design - The Director may approve an alternative final cover design that includes:

(1) An infiltration layer that achieves an equivalent reduction in infiltration as the infiltration layer specified in paragraph (a)(1) of this section, and

(2) An erosion layer that provides equivalent protection from wind and water erosion as the erosion layer specified in (a)(2) of this section.

(c) Closure Plans - The owner or operator must prepare a written closure plan that describes the steps necessary to close all landfill units at any point during its active life in accordance with the cover design requirements in (a) or (b) of this section, as applicable. The closure plan, at a minimum, must include the following information:

(1) A description of the final cover, designed in accordance with paragraph (a) or (b) of this section and the methods and procedures to be used to install the cover;

(2) An estimate of the largest area of the unit ever requiring a final cover at any time during the active life;

(3) An estimate of the maximum inventory of wastes ever on-site over the active life of the landfill facility; and

(4) A schedule for completing all activities necessary to satisfy the closure criteria in this section.

(d) Closure Plan Approval - The owner or operator of all Class 1, Class 3, and Class 4 landfills shall prepare a closure plan meeting the requirements of this Chapter, place the closure plan in the operating record, and submit the closure plan to the Division for approval with the application for a new landfill permit or no later than:

(1) The compliance date specified in Rule 22.103(f) for all Class 1 landfills; or

(2) May 7, 1995 for all Class 3 and Class 4 landfills.

(e) Notification of Closed Landfill or Completed Unit - The landfill owner or operator shall notify the Division when the landfill or a landfill unit stops receiving wastes for disposal and place the notice in the operating record.

(f) Timely Initiation of Closure Required - The owner or operator must begin closure activities of each landfill unit no later than thirty (30) days after:

1. the date on which the unit receives the known final receipt of wastes; or

2. when the unit has reached its final permitted elevations; or

3. if the unit has remaining capacity and there is a reasonable likelihood that the unit will receive additional wastes, no later than one (1) year after the most recent receipt of wastes.

Extensions beyond the one (1) year deadline for beginning closure may be granted by the Director if the owner or operator demonstrates that the unit has the capacity to receive additional wastes and the owner or operator has taken and will continue to take all steps necessary to prevent threats to human health and the environment from the unclosed unit.

(g) Timely Completion of Closure Required - The owner or operator of all landfill units must complete closure activities of each unit in accordance with the approved closure plan within one hundred eighty (180) days following the beginning of closure as specified in paragraph (f) of this section. Extensions of the closure period may be granted by the Director if the owner or operator demonstrates that closure will, of necessity, take longer than one hundred eighty (180) days and he has taken and will continue to take all steps to prevent threats to human health and the environment from the unclosed unit.

(h) Proper Grading Required - The entire site shall be graded prior to installation of the cover system so that storm water does not run onto the landfill and so that there are no depressions in the landfill where water can pond. Erosion control measures shall be implemented as necessary to protect the final cover and prevent off-site sedimentation.

(i) Site Survey - Upon completion of the final cover, the site shall be surveyed by a professional land surveyor or professional engineer registered in the State of Arkansas to document the final elevations of the landfill, the location of all surface improvements such as monitoring points, the site boundaries, and the areas that received wastes. Other permanent features such as benchmarks, access roads, buildings, gas monitoring, collection and processing systems, leachate collection, removal and storage systems, and any run-on and run-off control systems should also be shown on the final survey.

(j) Recording of Land Use Restriction - Following closure of all units, the owner or operator shall record a notation on the deed to the landfill facility property, or some other instrument that is normally examined during title search. A copy of the file marked deed notation shall be furnished to the Division and a copy shall be placed in the operating record. The notation on the deed must in perpetuity notify any potential purchaser of the property of:

(1) The past use of the land as a landfill facility;

(2) Future land uses shall comply with Pollution Control and Ecology Commission rules and shall not disturb the integrity of the final cover system, the liner system, or any other components of the containment or monitoring system; and

(3) In accordance with A.C.A. § 8-6-1404, it shall be unlawful for any person, partnership, company, corporation or other entity to build, erect, or construct any house, home, or building to be used for a residential purpose .

(5) The survey plot and record of the location and quantity of asbestos containing waste disposed of within the disposal site required in Rule Number 21, Arkansas Asbestos Abatement Rule, have been filed with the Division.

The owner or operator may request permission from the Director to remove the notation from the deed if all wastes are removed from the facility.

(k) Land Use Restriction Applicability - Restrictions on land uses shall apply only to the area or areas used for the actual disposal of solid waste. The residential land use restriction shall not apply to residential structures that were in existence and in use as of August 13, 1993 or to landfills that stopped accepting waste for disposal prior to August 13, 1968.

(l) Certification of Closure - Following closure of each unit, the owner or operator must furnish the Director a certification, signed by a professional engineer registered in the State of Arkansas, verifying that closure has been completed in accordance with the closure plan, and that this certification has been placed in the operating record. A final closure report shall accompany the certification that includes:

(1) The final survey in accordance with paragraph (i);

(2) Quality control and quality assurance data documenting proper construction and installation of the cover system.

(3) A copy of the deed notation required under paragraph (j).

(4) Other information that the Division may deem necessary to making the certification described in paragraph (h).

(m) Division Certification of Closure - Closure must be timely and approved in writing by the Division if the facility is to be eligible for inclusion under the Arkansas Landfill Post Closure Trust Fund. Upon written request, the Division will inspect the site for conformance to closure requirements. Division written certification of closure begins the post closure period.

(b) Any expenditures in excess of $50,000.00 per site from the Landfill Post-closure Trust Fund, for corrective action for remedy to environmental impacts of closed disposal sites previously operated as a landfill pursuant to state law, will be prioritized and authorized by the Commission, by adoption of a Minute Order, after addressing corrective actions needed to address environmental impacts from permitted landfills closed properly.

Chapter 14 Financial Assurance Criteria

Rule 22.1401 - Applicability And Effective Date

(a) General - This Chapter addresses financial assurance requirements for Class 1, 3, and 4 landfill facilities as well as solid waste processing facilities that are required to post financial assurance. Unless otherwise noted in this section, compliance is required on the effective date of the rule.

(b) Landfills - The requirements of Rule 22.1402 through Rule 22.1406 apply to the owners and operators of all permitted Class 1, 3, and 4 landfills as provided in 40 CFR § 258.70 except owners or operators who are State or Federal Government Entities whose debts and liabilities are the debts and liabilities of the State or the United States.

(c) Processing Facilities - Owners or operators of solid waste processing facilities that are required by the Director to post financial assurance shall select a financial assurance mechanism from those allowable mechanisms identified in Rule 22.1405 and must comply with the provisions of Rule 22.1406. The closure requirements of Rule 22.1402, the post-closure requirements of Rule 22.1403 and the corrective action requirements of Rule 22.1404 do not apply to solid waste processing facilities. Instead, the owners or operators of solid waste processing facilities must comply with the closure requirements of:

(1) Rule 22.810 for compost facilities;

(2) Rule 22.907 for transfer stations; or

(3) Rule 22.1007 for solid waste recovery facilities.

Rule 22.1402 - Financial Assurance For Closure

(a) Closure Cost Estimate - As provided in 40 CFR 258.71, the owner, or operator of all permitted landfill facilities must have and maintain a detailed written estimate, in current dollars, of the cost of hiring a third party to close the largest area of all permitted facilities ever requiring a final cover as required under Rule 22.1301(c) at any time during the active life in accordance with the closure plan. The owner or operator shall provide the initial and updated estimates to the Director and shall place the estimates in the operating record.

(1) The cost estimate must equal the cost of closing the largest area of all permitted facilities ever requiring a final cover at any time during the active life when the extent and manner of its operation would make closure the most expensive, as indicated by its closure plan (see Rule 22.1301).

(2) During the active life of the permitted facility, the owner or operator must annually adjust the closure cost estimate for inflation.

(3) The owner or operator must increase the closure cost estimate and the amount of financial assurance provided under paragraph (b) of this section if changes to the closure plan or permitted facility conditions increase the maximum cost of closure at any time during the remaining active life.

(4) With Division approval, the owner or operator may reduce the closure cost estimate and the amount of financial assurance provided under paragraph (b) of this section if the cost estimate exceeds the maximum cost of closure at any time during the remaining life of the permitted facility. The owner or operator must provide the justification to the Director for the reduction of the closure cost estimate and place the justification in the operating record.

(b) Financial Assurance for Closure - The owner or operator of each permitted facility must establish and at all times maintain financial assurance for closure of the permitted facility in compliance with Rule 22.1405. The owner or operator must provide continuous coverage for closure until released from financial assurance requirements by demonstrating compliance with Rule 22.1301 (l) and (m).

Rule 22.1403 - Financial Assurance For Post-Closure Care

(a) Post-Closure Cost Estimate - As provided in 40 CFR 258.72, the owner, or operator of all permitted landfill facilities must have a detailed written estimate, in current dollars, of the cost of hiring a third party to conduct post-closure care for the permitted facility in compliance with the post-closure plan developed under Rule 22.1302(c). The post-closure cost estimate used to demonstrate financial assurance in paragraph (b) of this section must account for the total costs of conducting post-closure care, including annual and periodic costs as described in the post-closure plan over the entire postclosure care period. The owner or operator shall provide the initial and updated estimates to the Director and shall place the estimates in the operating record.

(1) The cost estimate for post-closure care must be based on the most expensive costs of post closure care during the post-closure care period.

(2) During the active life of the permitted facility and during the post-closure care period, the owner or operator must annually adjust the post-closure cost estimate for inflation.

(3) The owner or operator must increase the post-closure care cost estimate and the amount of financial assurance provided under paragraph (b) of this section if changes in the postclosure plan or permitted facility conditions increase the maximum costs of post-closure care.

(4) With Division approval, the owner or operator may reduce the post-closure cost estimate and the amount of financial assurance provided under paragraph (b) of this section if the cost estimate exceeds the maximum costs of post-closure care remaining over the post-closure care period. The owner or operator must provide the justification to the Director for the reduction of the closure cost estimate and place the justification in the operating record.

(b) Financial Assurance for Post-Closure - Except as provided in paragraph (c) below, the owner or operator of each permitted facility must establish and at all times maintain, in a manner in accordance with Rule 22.1405, financial assurance for 100% of the costs of post-closure care as required under Rule 22.1302. The owner or operator must provide continuous coverage for postclosure care until released from financial assurance requirements for post-closure care by demonstrating compliance with Rule 22.1302(f).

(c) Post Closure Trust Fund Guarantee - Owners or operators that are required by law to pay disposal fees into the post closure trust fund (Generally, Class 1, Class 3C, and Class 4 landfills) may elect to provide financial assurance in an amount not less than twenty (20) percent of estimated post-closure maintenance costs through a financial mechanism readily negotiable by the division to cash funds (e.g., letter of credit, surety bond, irrevocable trust, insurance, or other mechanism approved by the division) upon default by the owner and operator of post-closure obligations.

(1) If, after proper closure of the landfill, the division reasonably determines that the owner or operator cannot be located or cannot otherwise satisfy, in whole or part, post-closure maintenance obligations, the division is authorized to expend the necessary funds from the Post-Closure Trust Fund to satisfy the requirements of state and federal law for post closure care and to prevent or abate releases to the environment.

(2) If the division is required to expend funds from the Post-Closure Trust Fund due to the failure of an owner or operator to meet the requirements of this subsection, the division shall first pursue collection and recovery of the funds by issuing an Administrative Order notifying the owner or operator by certified mail at the last known address of the owner or operator of the action taken by the division and the amount of funds expended from the Fund, and that the Administrative Order may be appealed in accordance with the Division's rules.

(3) Nothing contained herein shall be construed to limit the Division's ability to pursue other legal remedies for the recovery of Post-Closure Trust Funds expended on post closure care, or as releasing an owner or operator from performing 100% of its post closure care obligations under this rule.

Rule 22.1404 - Financial Assurance For Corrective Action

(a) Corrective Action Cost Estimate - As provided in 40 CFR 258.73 an owner or operator of a permitted facility required to undertake a corrective action program under Rule 22.1208 of this part must have a detailed written estimate, in current dollars, of the cost of hiring a third party to perform the corrective action in accordance with the program required under Rule 22.1208. The corrective action cost estimate must account for the total costs of corrective action activities as described in the corrective action plan for the entire corrective action period. The owner or operator must provide the cost estimate to the Director for approval and place the estimate in the operating record.

(1) The owner or operator must annually adjust the estimate for inflation until the corrective action program is completed in accordance with Rule 22.1208.

(2) The owner or operator must increase the corrective action cost estimate and the amount of financial assurance provided under paragraph (b) of this section if changes in the corrective action program or permitted facility conditions increase the maximum costs of corrective action.

(3) The owner or operator may, upon approval by the Director, reduce the amount of the corrective action cost estimate and the amount of financial assurance provided under paragraph (b) of this section if the cost estimate exceeds the maximum remaining costs of corrective action. The owner or operator must provide the justification for the reduction of the corrective action cost estimate and the amount of financial assurance to the Director for approval and place the justification and revised cost estimate in the operating record.

(b) Financial Assurance for Corrective Action - The owner or operator of each permitted facility required to undertake a corrective action program under Rule 22.1208 must establish, in a manner in accordance with Rule 22.1405, financial assurance for the most recent corrective action program. The owner or operator must provide continuous coverage for corrective action until released from financial assurance requirements for corrective action by demonstrating compliance with Rule 22.1208(f) and (g).

Rule 22.1405 - Allowable Mechanisms

As provided in 40 CFR 258.74 the mechanisms used to demonstrate financial assurance under this Chapter must ensure that the funds necessary to meet the costs of closure, post-closure care, and corrective action for known releases will be available whenever they are needed. Owners and operators must choose from the options specified in paragraphs (a) through (j) of this section. Financial assurance required by this chapter should be filed on forms developed and provided by the division.

(a) Trust Fund

(1) An owner or operator may satisfy the requirements of this section by establishing a trust fund which conforms to the requirements of this paragraph. The trustee must 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. A copy of the trust agreement must be placed in the facility's operating record and provided to the Director for approval.

(2) Payments into the trust fund must be made annually by the owner or operator over the term of the initial permit or over the remaining life of the permitted facility, whichever is shorter, in the case of a trust fund for closure or post-closure care, or over one-half of the estimated length of the corrective action program in the case of corrective action for known releases. This period is referred to as the pay-in period.

(3) For a trust fund used to demonstrate financial assurance for closure and post-closure care, the first payment into the fund must be at least equal to the current cost estimate for closure or post-closure care, except as provided in paragraph (j) of this section, divided by the number of years in the pay-in period as defined in paragraph (a)(2) of this section. The amount of subsequent payments must be determined by the following formula:

where CE is the current cost estimate for closure or post-closure care (updated for inflation or other changes), CV is the current value of the trust fund, and Y is the number of years remaining in the pay-in period.

(4) For a trust fund used to demonstrate financial assurance for corrective action, the first payment into the trust fund must be at least equal to one-half of the current cost estimate for corrective action, except as provided in paragraph (j) of this section, divided by the number of years in the corrective action pay-in period as defined in paragraph (a)(2) of this section. The amount of subsequent payments must be determined by the following formula:

where RB is the most recent estimate of the required trust fund balance for corrective action (i.e., the total costs that will be incurred during the second half of the corrective action period), CV is the current value of the trust fund, and Y is the number of years remaining on the pay-in period.

(5) The initial payment into the trust fund must be made before the initial receipt of waste or before the effective date of this section (April 9, 1997), whichever is later, in the case of closure and post-closure care, or no later than one hundred twenty (120) days after the corrective action remedy has been selected in accordance with the requirements of Rule 22.1208.

(6) If the owner or operator establishes a trust fund after having used one or more alternate mechanisms specified in this section, the initial payment into the trust fund must be at least the amount that the fund would contain if the trust fund were established initially and annual payments made according to the specifications of this paragraph and (a) of this section, as applicable.

(7) The owner or operator, or other person authorized to conduct closure, post-closure care, or corrective action activities may request reimbursement from the trustee for these expenditures. Requests for reimbursement will be granted by the trustee only if sufficient funds are remaining in the trust fund to cover the remaining costs of closure, post-closure care, or corrective action, and if justification and documentation of the cost is placed in the operating record. Within 30 days of disbursement, or an alternative schedule acceptable to the Director, the trustee shall notify the Director of each reimbursement made from the trust fund. The owner or operator shall provide a copy of the documentation of the justification for reimbursement to the Director and place the justification for reimbursement in the operating record.

(8) The trust fund may be terminated by the owner or operator only if the owner or operator substitutes alternate financial assurance as specified in this section or if he is no longer required to demonstrate financial responsibility in accordance with the requirements of Rule 22.1402(b), Rule 22.1403(b), or Rule 22.1404(b).

(b) Surety Bond Guaranteeing Payment or Performance

(1) An owner or operator may demonstrate financial assurance for closure or post-closure care by obtaining a payment or performance surety bond which conforms to the requirements of this paragraph. An owner or operator may demonstrate financial assurance for corrective action by obtaining a performance bond which conforms to the requirements of this paragraph. The bond must be effective before the initial receipt of waste or before the effective date of this section, (April 9, 1997), whichever is later, in the case of closure and post-closure care, or no later than one hundred twenty (120) days after the corrective action remedy has been selected in accordance with the requirements of Rule 22.1208. The owner or operator shall provide the bond to the Director for approval and place a copy of the bond in the operating record. 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 penal sum of the bond must be in an amount at least equal to the current closure, postclosure care or corrective action cost estimate, whichever is applicable, except as provided in (k) of this section.

(3) 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.

(4) The owner or operator must establish a standby trust fund. The standby trust fund must meet the requirements of (a) of this section except the requirements for initial payment and subsequent annual payments specified in (a)(2), (3), (4) and (5) of this section.

(5) Payments made under the terms of the bond will be deposited by the surety directly into the standby trust fund. Payments from the trust fund must be approved by the trustee.

(6) Under the terms of the bond, the surety may cancel the bond by sending notice of cancellation by certified mail to the owner and operator and to the Director one hundred twenty (120) days in advance of cancellation. If the surety cancels the bond, the owner or operator must obtain alternate financial assurance as specified in this section.

(7) The owner or operator may cancel the bond only if alternate financial assurance is substituted as specified in this section or if the owner or operator is no longer required to demonstrate financial responsibility in accordance with Rule 22.1402(b), 22.1403(b), or 22.1404(b).

(1) An owner or operator may satisfy the requirements of this section by obtaining an irrevocable standby letter of credit which conforms to the requirements of this paragraph. The letter of credit must be effective before the initial receipt of waste or before the effective date of this section, (April 9, 1997), whichever is later, in the case of closure and postclosure care, or no later than one hundred twenty (120) days after the corrective action remedy has been selected in accordance with the requirements of Rule 22.1208. The owner or operator shall provide the letter of credit to the Director for approval and place a copy of the letter of credit in the operating record. The issuing institution must 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.

(2) A letter from the owner or operator referring to the letter of credit by number, issuing institution, and date, and providing the following information: name, and address of the facility, and the amount of funds assured, must be included with the letter of credit, which shall be provided to the Director and shall be placed in the operating record.

(3) The letter of credit must be irrevocable and issued for a period of at least one year in an amount at least equal to the current cost estimate for closure, post-closure care or corrective action, whichever is applicable, except as provided in (a) of this section. The letter of credit must provide that the expiration date will be automatically extended for a period of at least one year unless the issuing institution has canceled the letter of credit by sending notice of cancellation by certified mail to the owner and operator and to the Director one hundred twenty (120) days in advance of cancellation. If the letter of credit is canceled by the issuing institution, the owner or operator must obtain alternate financial assurance.

(4) The owner or operator may cancel the letter of credit only if alternate financial assurance is substituted as specified in this section or if the owner or operator is released from the requirements of this section in accordance with Rule 22.1402(b), Rule 22.1403(b) or Rule 22.1404(b).

(d) Insurance

(1) An owner or operator may demonstrate financial assurance for closure and post-closure care by obtaining insurance which conforms to the requirements of this paragraph. The insurance must be effective before the initial receipt of waste or before the effective date of this section, (April 9, 1997), whichever is later. At a minimum, the insurer must be licensed to transact the business of insurance, or eligible to provide insurance as an excess or surplus lines insurer, in the State of Arkansas. The owner or operator shall provide the insurance policy to the Director for approval and placea copy of the insurance policy in the operating record.

(2) The closure or post-closure care insurance policy must guarantee that funds will be available to close the permitted facility whenever final closure occurs or to provide post-closure care for the permitted facility whenever the post-closure care period begins, whichever is applicable. The policy must also guarantee that once closure or post-closure care begins, the insurer will be responsible for the paying out of funds to the owner or operator or other person authorized to conduct closure or post-closure care, up to an amount equal to the face amount of the policy.

(3) The insurance policy must be issued for a face amount at least equal to the current cost estimate for closure or post-closure care, whichever is applicable, except as provided in (a) of this section. 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) An owner or operator, or any other person authorized to conduct closure or post-closure care, may receive reimbursements for closure or post-closure expenditures, whichever is applicable. Requests for reimbursement will be granted by the insurer only if the remaining value of the policy is sufficient to cover the remaining costs of closure or post-closure care, and if justification and documentation of the cost is placed in the operating record. The owner or operator must notify the Director that the documentation of the justification for reimbursement has been placed in the operating record and that reimbursement has been received, and provide of copy of the justification to the Director if requested.

(5) Each policy must 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 that such consent is not unreasonably refused.

(6) The insurance 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 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 cancel the policy by sending notice of cancellation by certified mail to the owner and operator and to the Director one hundred twenty (120) days in advance of cancellation. If the insurer cancels the policy, the owner or operator must obtain alternate financial assurance as specified in this section.

(7) For insurance policies providing coverage for post-closure care, 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 must be equivalent to the face amount 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.

(8) The owner or operator may cancel the insurance policy only if alternate financial assurance is substituted as specified in this section or if the owner or operator is no longer required to demonstrate financial responsibility in accordance with the requirements of Rule 22.1402(b), Rule 22.1403(b) or Rule 22.1404(b).

(e) Corporate Financial Test - An owner or operator that satisfies the requirements of this paragraph may demonstrate financial assurance up to the amount specified in this paragraph (e):

(1) Financial Component

(i) The owner or operator must satisfy one of the following three conditions:

(A) A current rating for its senior unsubordinated debt of AAA, AA, A, or BBB as issued by Standard and Poor's or Aaa, Aa, A or Baa as issued by Moody's; or

(B) A ratio of less than 1.5 comparing total liabilities to net worth; or

(C) A ratio of greater than 0.10 comparing the sum of net income plus depreciation, depletion and amortization, minus $10 million, to total liabilities.

(ii) The tangible net worth of the owner or operator must be greater than:

(A) The sum of the current closure, post-closure care, corrective action cost estimates and any other environmental obligations, including guarantees, covered by a financial test plus $10 million except as provided in paragraph (e)(1)(ii)(B) of this section.

(B) $10 million in net worth plus the amount of any guarantees that have not been recognized as liabilities on the financial statements provided all of the current closure, post-closure care, and corrective action costs and any other environmental obligations covered by a financial test are recognized as liabilities on the owner's or operator's audited financial statements, and subject to the approval of the Director.

(iii) The owner or operator must have assets located in the United States amounting to at least the sum of current closure, post-closure care, corrective action cost estimates and any other environmental obligations covered by a financial test as described in paragraph (e)(3) of this section.

(2) Recordkeeping and Reporting Requirements

(i) The owner or operator must place the following items into the facility's operating record and furnish those records to the Director for approval:

(A) A letter signed by the owner's or operator's chief financial officer that:

a. Lists all the current cost estimates covered by a financial test, including, but not limited to, cost estimates required for municipal solid waste management facilities under this part 258, cost estimates required for UIC facilities under 40 CFR part 144 , if applicable, cost estimates required for petroleum underground storage tank facilities under 40 CFR part 280 , if applicable, cost estimates required for PCB storage facilities under 40 CFR part 761 , if applicable, and cost estimates required for hazardous waste treatment, storage, and disposal facilities under 40 CFR parts 264 and 265, if applicable; and

(B) A copy of the independent certified public accountant's unqualified opinion of the owner's or operator's financial statements for the latest completed fiscal year. To be eligible to use the financial test, the owner's or operator's financial statements must receive an unqualified opinion from the independent certified public accountant. An adverse opinion, disclaimer of opinion, or other qualified opinion will be cause for disallowance, with the potential exception for qualified opinions provided in the next sentence. The Director may evaluate qualified opinions on a case-by-case basis and allow use of the financial test in cases where the Director deems that the matters which form the basis for the qualification are insufficient to warrant disallowance of the test. If the Director does not allow use of the test, the owner or operator must provide alternate financial assurance that meets the requirements of this section.

(C) If the chief financial officer's letter providing evidence of financial assurance includes financial data showing that owner or operator satisfies paragraph (e)(1)(i)(B) or (e)(1)(i)(C) of this section that are different from data in the audited financial statements referred to in paragraph (e)(2)(i)(B) of this section or any other audited financial statement or data filed with the SEC, then a special report from the owner's or operator's independent certified public accountant to the owner or operator is required. The special report shall be based upon an agreed upon procedures engagement in accordance with professional auditing standards and shall describe the procedures performed in comparing the data in the chief financial officer's letter derived from the independently audited, year-end financial statements for the latest fiscal year with the amounts in such financial statements, the findings of that comparison, and the reasons for any differences.

(D) If the chief financial officer's letter provides a demonstration that the firm has assured for environmental obligations as provided in paragraph (e)(1)(ii)(B) of this section, then the letter shall include a report from the independent certified public accountant that verifies that all of the environmental obligations covered by a financial test have been recognized as liabilities on the audited financial statements, how these obligations have been measured and reported, and that the tangible net worth of the firm is at least $10 million plus the amount of any guarantees provided.

(ii) An owner or operator must place the items specified in paragraph (e)(2)(i) of this section in the operating record, notify the Director that these items have been placed in the operating record, and submit the items to the Director for approval before the initial receipt of waste or before the effective date of the requirements of this section (April 9, 1997), whichever is later in the case of closure, and postclosure care, or no later than 120 days after the corrective action remedy has been selected in accordance with the requirements of Rule 22.1208.

(iii) After the initial placement of items specified in paragraph (e)(2)(i) of this section in the operating record, the owner or operator must annually update the information, place updated information in the operating record within 90 days following the close of the owner or operator's fiscal year, and furnish the information to the Director for approval. The Director may provide up to an additional 45 days for an owner or operator who can demonstrate that 90 days is insufficient time to acquire audited financial statements. The updated information must consist of all items specified in paragraph (e)(2)(i) of this section.

(iv) The owner or operator is no longer required to submit the items specified in this paragraph (e)(2) or comply with the requirements of this paragraph (e) when the owner or operator::

(A) Substitutes alternate financial assurance as specified in this section that is not subject to these recordkeeping and reporting requirements; or

(B) Is released from the requirements of this section in accordance with Rule 22.1402(b), Rule 22.1403(b) or Rule 22.1404(b).

(v) If the owner or operator no longer meets the requirements of paragraph (e)(1) of this section, the owner or operator must, within 120 days following the close of the owner or operator's fiscal year, obtain alternative financial assurance that meets the requirements of this section, place the required submissions for that assurance in the operating record, and notify the Director that the owner or operator no longer meets the criteria of the financial test and submit the alternate financial assurance for approval.

(vi) The Director may, based on a reasonable belief that the owner or operator may no longer meet the requirements of paragraph (e)(1) of this section, require at any time the owner or operator to provide reports of its financial condition in addition to or including current financial test documentation as specified in paragraph (e)(2) of this section. If the Director finds that the owner or operator no longer meets the requirements of paragraph (e)(1) of this section, the owner or operator must provide alternate financial assurance that meets the requirements of this section.

(3) Calculation of Costs to be Assured - When calculating the current cost estimates for closure, post-closure care, corrective action, or the sum of the combination of such costs to be covered, and any other environmental obligations assured by a financial test referred to in this paragraph (e), the owner or operator must include cost estimates required for solid waste management facilities under this part, as well as cost estimates required for the following environmental obligations, if it assures them through a financial test: obligations associated with UIC facilities under 40 CFR part 144 , petroleum underground storage tank facilities under 40 CFR part 280 , PCB storage facilities under 40 CFR part 761 , and hazardous waste treatment, storage, and disposal facilities under 40 CFR parts 264 and 265.

(f) Local Government Financial Test - An owner or operator may use a financial test to demonstrate financial assurance for closure, post-closure care and corrective action costs up to a specified maximum limit. An owner or operator that satisfies the requirements of paragraphs (1) through (3) of this section may demonstrate financial assurance up to the amount specified in paragraph (4) of this section.

(1) Financial Component

(i) The local government owner or operator must satisfy paragraph A - Bond Rating Requirement or paragraph B - Financial Ratio Alternative of this section in order to qualify to use the financial test.

(A) If the owner or operator has outstanding, rated, general obligation bonds that are not secured by insurance, a letter of credit, or other collateral or guarantee, it must have a current rating of Aaa, As, A, or Baa, as issued by Moody's; or AAA, AA, A, or BBB, as issued by Standard and Poor's on all such general obligation bonds; or

(B) The owner or operator must satisfy each of the following financial ratios based on the owner or operator's most recent audited annual financial statement:

a. A ratio of cash plus marketable securities to total expenditures greater than or equal to 0.05; and

b. A ratio of annual debt service to total expenditures less than or equal to 0.20.

(ii) The local government owner or operator must prepare its financial statements in conformity with Generally Accepted Accounting Principles for governments and have its financial statements audited by an independent certified public accountant (or appropriate State agency).

(iii) A local government is not eligible to assure its obligations under this section if it:

(A) Is currently in default on any outstanding general obligation bonds; or

(B) Has any outstanding general obligation bonds rated lower than Baa as issued by Moodys or BBB as issued by Standard and Poors; or

(D) Receives an adverse opinion, disclaimer of opinion, or other qualified opinion from the independent certified public accountant (or appropriate State agency) auditing its financial statement as required under paragraph Rule 22.1405 (f)(1)(ii). However, the Director of an approved State may evaluate qualified opinions on a case-by-case basis and allow use of the financial test in cases where the Director deems the qualification insufficient to warrant disallowance of the use of the test.

(iv) The following terms used in this paragraph are defined as follows:

(A) Deficit equals total annual revenues minus total annual expenditures.

(B) Total revenues include revenues from all taxes and fees but does not include the proceeds from borrowing or asset sales, excluding revenue from funds managed by local government on behalf of a specific third party;

(D) Cash plus marketable securities is all the cash plus marketable securities held by the local government on the last day of a fiscal year, excluding cash and marketable securities designated to satisfy past obligations such as pensions; and

(E) Debt service is the amount of principal and interest due on a loan in a given time period, typically the current year.

(2) Public Notice Component - The local government owner or operator must place a reference to the closure and post-closure care costs assured through the financial test into its next comprehensive annual financial report (CAFR) after the effective date of this section or prior to the initial receipt of waste at the facility, whichever is later. Disclosure must include the nature and source of closure and post-closure care requirements, the reported liability at the balance sheet date, the estimated total closure and post-closure care cost remaining to be recognized, the percentage of landfill capacity used to date, and the estimated landfill life in years. A reference to corrective action costs must be placed in the CAFR not later than 120 days after the corrective action remedy has been selected in accordance with the requirements of 22.1208. For the first year the financial test is used to assure costs at a particular facility, the reference may instead be placed in the operating record until issuance of the next available CAFR if timing does not permit the reference to be incorporated into the most recently issued CAFR or budget. For closure and post-closure costs, conformance with Government Accounting Standards Board Statement 18 assures compliance with this public notice component.

(3) Recordkeeping and Reporting Requirements

(i) The local government owner or operator must place the following documentation in the facility's operating record and furnish the information to the Director for approval:

(A) A letter signed by the local government's chief financial officer that:

a. Lists all the current cost estimates covered by a financial test, as described in Rule 22.1405(f)(4) of this section;

b. Provides evidence and certifies that the local government meets the conditions of Rule .22.1405(f)(1)(i), (f)(1)(ii), and (f)(1)(iii); and

(ii) The items required in Rule 22.1405(f)(3)(i) must be placed in the facility operating record as follows:

(A) In the case of closure and post-closure care, either before the effective date of this section, which is April 9, 1997, or prior to the initial receipt of waste at the facility, whichever is later, or

(B) In the case of corrective action, not later than 120 days after the corrective action remedy is selected in accordance with the requirements of Rule 22.1208

(iii) After the initial placement of the items in the facility's operating record, the local government owner or operator must update the information and place the updated information in the operating record within 180 days following the close of the owner or operator's fiscal year.

(vi) The Director, based on a reasonable belief that the local government owner or operator may no longer meet the requirements of the local government financial test, may require additional reports of financial condition from the local government at any time. If the Director of an approved State finds, on the basis of such reports or other information, that the owner or operator no longer meets the requirements of the local government financial test, the local government must provide alternate financial assurance in accordance with this section.

(4) Calculation of Costs to be Assured - The portion of the closure, post-closure care, and corrective action costs for which an owner or operator can assure under this paragraph is determined as follows:

The guarantor must 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 must meet the requirements for owners or operators in paragraph (e) of this section and must comply with the terms of the guarantee. A certified copy of the guarantee must be placed in the facility's operating record and furnished to the Director for approval along with copies of the letter from the guarantor's chief financial officer and accountants' opinions. If the guarantor's parent corporation is also the parent corporation of the owner or operator, the letter from the guarantor's chief financial officer must 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 must describe this ``substantial business relationship'' and the value received in consideration of the guarantee.

If the owner or operator fails to provide alternate financial assurance within the 90-day period, the guarantor must provide that alternate assurance within 120 days of the cancellation notice, obtain alternative assurance, place evidence of the alternate assurance in the facility operating record, and submit the alternate financial assurance to the Director for approval.

(4) If a corporate guarantor no longer meets the requirements of paragraph (e)(1) of this section, the owner or operator must, within 90 days, obtain alternative assurance, place evidence of the alternate assurance in the facility operating record, and submit the alternate financial assurance to the Director for approval.

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

(ii) The owner or operator is released from the requirements of this section in accordance with Rule 22.1402(b), Rule 22.1403(b), or Rule 22.1404(b).

(1) Terms of the Written Guarantee

The guarantee must be effective before the initial receipt of waste or before the effective date of this section, whichever is later, in the case of closure, post-closure care, or no later than 120 days after the corrective action remedy has been selected in accordance with the requirements of 22.1208. The guarantee must provide that:

(i) If the owner or operator fails to perform closure, post-closure care, and/or corrective action of a facility covered by the guarantee, the guarantor will:

(A) Perform, or pay a third party to perform, closure, post-closure care, and/or corrective action as required; or

(B) Establish a fully funded trust fund as specified in Rule 22.1405(a) in the name of the owner or operator.

(ii) The guarantee will remain in force unless the guarantor sends notice of cancellation by certified mail to the owner or operator and to the Director.

If the owner or operator fails to obtain alternate financial assurance within that 90-day period, the guarantor must provide that alternate assurance within the next 30 days.

(i) State Approved Mechanism. An owner or operator may satisfy the requirements of this section by obtaining any other mechanism that meets the criteria specified in (l) of this section, and that is approved by the Director.

(j) State Assumption of Responsibility - If the Director either assumes legal responsibility for an owner or operator's compliance with the closure, post-closure care and corrective action requirements of this part, or assures that the funds will be available from State sources to cover the requirements, the owner or operator will be in compliance with the requirements of this section. Any State assumption of responsibility must meet the criteria specified in (l) of this section.

(k) Use of Multiple Financial Mechanisms - An owner or operator may satisfy the requirements of this section demonstrate financial assurance for closure, post-closure, and corrective action, as required by Rule 22.1402, Rule 22.1403, and Rule 22.1404 by establishing more than one financial mechanism per facility, except that mechanisms guaranteeing performance rather than payment, may not be combined with other instruments. The mechanisms must be as specified in paragraphs (a), (b), (c), (d), (e), (f), (g), (h), (i), (j), and k of this section, except that financial assurance for an amount at least equal to the current cost estimate for closure, post-closure care and/or corrective action, may be provided by a combination of mechanisms rather than a single mechanism.

(l) Financial Assurance Sufficiency - The language of the mechanisms listed in paragraphs (a), (b), (c), (d), (e), (f), (g), (h), (i), (j) and (k) of this section must ensure that the instruments satisfy the following criteria:

(1) The financial assurance mechanisms must ensure that the amount of funds assured is sufficient to cover the costs of closure, post-closure care, and corrective action for known releases when needed;

(2) The financial assurance mechanisms must ensure that funds will be available in a timely fashion when needed;

(3) The financial assurance mechanisms must be obtained by the owner or operator by the effective date of these requirements or prior to the initial receipt of solid waste, whichever is later, in the case of closure and post-closure care, and no later than one hundred twenty (120) days after the corrective action remedy has been selected in accordance with the requirements of Rule 22.1208, until the owner or operator is released from the financial assurance requirements under Rule 22.1402, Rule 22.1403 and Rule 22.1404.

(4) The financial assurance mechanisms must be legally valid, binding, and enforceable under State and Federal law.

(m) Use of a Financial Mechanism for Multiple Facilities - The owner or operator may use a single financial assurance mechanism to meet financial assurance requirements for more than one permitted facility located in Arkansas. The mechanism submitted to the Director must include a list showing, for each facility, the permit number, name, address, and amount of funds for closure, and postclosure care or corrective action assured by the mechanism. The amount of funds available through the mechanism must be no less than the sum of funds that would be available if a separate mechanism had been filed and maintained for each facility. In a financial assurance forfeiture action for any of the facilities covered by the mechanism, the Director may order forfeiture of only the amount of funds designated for that facility, unless the permittee agrees to the use of additional funds available under the mechanism.

(1) A municipality or county may satisfy the requirements of this section by executing a contract of obligation with the Division which conforms to the requirements of this paragraph. The contract of obligation shall be a binding, enforceable, agreement on the municipality or county, allowing the Division to collect the required amount from any funds being disbursed or to be disbursed from the State to the municipality or county.

(2) To assure compliance with paragraph (n) of this section, the maximum amount pledged under the contract of obligation shall not exceed the total amount of general revenue disbursed to the municipality or county in the last fiscal year, or, if approved by the Director, the amount currently projected by the State to be disbursed during the current fiscal year.

The contract of obligation must be effective before the initial receipt of waste or before the effective date of this section, (April 9, 1997), whichever is later, in the case of closure and post-closure care, or no later than one hundred twenty (120) days after the corrective action remedy has been selected in accordance with the requirements of Rule 22.1208.

(4) The owner or operator shall provide the contract of obligation to the Director for approval and place a copy of the contract of obligation in the operating record. Upon execution by the Director, the contract shall be filed with the State Commissioner of Revenues.

(5) The owner or operator may cancel the contract of obligation only if alternate financial assurance is substituted as specified in this section or if the owner or operator is released from the requirements of this section in accordance with Rule 22.1402(b), Rule 22.1403(b) or Rule 22.1404(b).

Notes

1. The regulatory requirements pertain only to the list of substances; the right hand columns (Methods and PQL) are given for informational purposes only. See also footnotes 5 and 6.

2. Common names are those widely used in government regulations, scientific publications, and commerce; synonyms exist for many chemicals.

3. Chemical Abstracts Service registry number. Where Total is entered, all species in the ground water that contain this element are included.

4. CAS index are those used in the 9th Collective Index.

5. Suggested Methods refer to analytical procedure numbers used in EPA Report SW-846 Test Methods for Evaluating Solid Waste, third edition, November 1986, as revised, December 1987. Analytical details can be found in SW-846 and in documentation on file at the agency. CAUTION: The methods listed are representative SW-846 procedures and may not always be the most suitable method(s) for monitoring an analyte under the regulations.

6. Practical Quantitation Limits (PQLs) are the lowest concentrations of analytes in ground waters that can be realiably determined within specified limits of precision and accuracy by the indicated methods under routine laboratory operating conditions. The PQLs listed are generally stated to one significant figure. PQLs are based on 5 mL samples for volatile organics and 1 L samples for semivolatile organics. CAUTION: The PQL values in many cases are based only on a general estimate for the method and not on a determination for individual compounds; PQLs are not a part of the regulation.

7. This substance is often called Bis(2-chloroisopropyl) ether, the name Chemical Abstracts Service applies to its noncommercial isomer, Propane, 2,2-oxybis[2-chloro- (CAS RN 39638-32-9) .

8. Chlordane: This entry includes alpha-chlordane (CAS RN 5103- 71-9), beta-chlordane (CAS RN 5103-74-2) , gamma-chlordane (CAS RN 5566-34-7) , and constituents of chlordane (CAS RN 57-74-9 and CAS RN 12789-03-6) . PQL shown is for technical chlordane. PQLs of specific isomers are about 20 (r)g/L by method 8270.

9. Polychlorinated biphenyls (CAS RN 1336-36-3) ; this category contains congener chemicals, including constituents of Aroclor 1016 CAS RN 12674-11-2) , Aroclor 1221 (CAS RN 11104-28-2) , Aroclor 1232 (CAS RN 11141-16-5) , Aroclor 1242 (CAS RN 53469-21-9) , Aroclor 1248 (CAS RN 12672-29-6) , Aroclor 1254 (CAS RN 11097- 69-1), and Aroclor 1260 (CAS RN 11096-82-5) . The PQL shown is an average value for PCB congeners.

10. Toxaphene: This entry includes congener chemicals contained in technical toxaphene (CAS RN 8001-35-2) , i.e., chlorinated camphene.

11. Xylene (total): This entry includes o-xylene (CAS RN 96-47-6) , m-xylene (CAS RN 108-38-3) , p-xylene (CAS RN 106-42-3) , and unspecified xylenes (dimethylbenzenes) (CAS RN 1330-20-7) . PQLs for method 8021 are 0.2 for o-xylene and 0.1 for m- or p-xylene. The PQL for m-xylene is 2.0 (r)g/L by method 8020 or 8260.

APPENDIX 3- Maximum Contaminant Levels (MCLs)

The maximum contaminant levels promulgated herein are for use in determining whether solid waste disposal activities comply with the ground-water criteria (40 CFR 257.3-4) for Class 3, Class 4 and other solid waste facilities and practices.
