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.

This schedule must ensure that 50 percent of all existing landfills are in compliance by October 9, 1994 and all existing landfills are in compliance by October 9, 1996. In setting the compliance schedule, the Director must consider potential risks posed by the unit to human health and the environment. The following factors should be considered in determining potential risk:

(1) Proximity of human and environmental receptors;

(2) Design of the landfill;

(3) Age of the landfill;

(4) The size of the landfill;

Rule 22.1202- Ground Water Monitoring Systems

(a) Applicability - As provided in Rule 22.1201(a), a ground water monitoring system must be installed that consists of a sufficient number of wells, installed at appropriate locations and depths, to yield ground-water samples from the uppermost aquifer (as defined in . Rule 22.102) that:

(1) Represent the quality of background ground water that has not been affected by leakage from a unit. A determination of background quality may include sampling of wells that are not hydraulically up gradient of the waste management area where:

(i) Hydrogeologic conditions do not allow the owner or operator to determine what wells are hydraulically up gradient; or

(ii) Sampling at other wells will provide an indication of background ground water quality that is as representative or more representative than that provided by the upgradient wells; and

(2) Represent the quality of ground water passing the relevant point of compliance specified by Director under Rule 22.424(d). The downgradient monitoring system must be installed at the relevant point of compliance specified by the Director under Rule 22.424(d) that ensures detection of ground water contamination in the uppermost aquifer. When physical obstacles preclude installation of ground water monitoring wells at the relevant point of compliance at existing units, the downgradient monitoring system may be installed at the closest practicable distance hydraulically downgradient from the relevant point of compliance specified by the Director under Rule 22.424(d) that ensures detection of ground water contamination in the uppermost aquifer.

(b) Multi-Unit Monitoring - The Director may approve a multi-unit ground water monitoring system instead of separate ground water monitoring systems for each landfill when the facility has several units, provided the multi-unit ground water monitoring system meets the requirement of Rule 22.1201 and will be as protective of human health and the environment as individual monitoring systems for each landfill, based on the following factors:

(1) Number, spacing, and orientation of the landfill units;

(2) Hydrogeologic setting;

(3) Site history;

(4) Engineering design of the landfills, and

(5) Type of waste accepted at the landfills.

(c) Well Construction and Decommissioning Requirements - Monitoring wells must be constructed in accordance with Rule 22.1103.

(1) The owner or operator must notify the Director that the design, installation, development, and decommission of any monitoring wells, piezometers and other measurement, sampling, and analytical devices documentation has been placed in the operating record; and

(2) The monitoring wells, piezometers, and other measurement, sampling, and analytical devices must be operated and maintained so that they perform to design specifications throughout the life of the monitoring program.

(d) Site-Specific Design - The number, spacing, and depths of monitoring systems shall be determined based upon site-specific technical information developed in accordance with the requirements of Chapter 11 that must include thorough characterization of:

(1) Aquifer thickness, ground-water flow rate, ground-water flow direction including seasonal and temporal fluctuations in ground-water flow; and

(2) Saturated and unsaturated geologic units and fill materials overlying the uppermost aquifer, materials comprising the uppermost aquifer, and materials comprising the confining unit defining the lower boundary of the uppermost aquifer; including, but not limited to: thicknesses, stratigraphy, lithology, hydraulic conductivities, porosities and effective porosities.

(e) Certification - The ground water monitoring system must be certified by a qualified ground water scientist or approved by the Director. Within fourteen (14) days of this certification, the owner or operator must notify the Director that the certification has been placed in the operating record.

Rule 22.1203- Ground Water Sampling And Analysis Requirements

(a) Consistency of Procedures - The ground water monitoring program must include consistent sampling and analysis procedures that are designed to ensure monitoring results that provide an accurate representation of ground water quality at the background and downgradient wells installed in compliance with Rule 22.1202(a). The owner or operator must notify the Director that the sampling and analysis program documentation has been placed in the operating record and the program must include procedures and techniques for:

(1) Sample collection;

(2) Sample preservation and shipment;

(3) Analytical procedures;

(4) Chain of custody control; and

(5) Quality assurance and quality control.

(b) Sampling and Analytical Methods - The ground water monitoring program must include sampling and analytical methods that are appropriate for ground water sampling and that accurately measure Appendix 1 parameters in ground water samples as specified in Rule 22.1204(d). Ground water samples shall not be field-filtered prior to laboratory analysis. Analytical methods utilized should conform SW-486 or the most current EPA approved analytical method. Primary Drinking Water Standard MCL's shall be superceded by the publication of new standards from EPA.

(c) Environmental Protection - The sampling procedures and frequency must be protective of human health and the environment.

(d) Determination of Groundwater Flow - Ground water elevations must be measured in each well immediately prior to purging, each time ground water is sampled. The owner or operator must determine the rate and direction of ground water flow each time ground water is sampled. Ground water elevations in wells which monitor the same waste management area must be measured within a period of time short enough to avoid temporal variations in ground water flow which could preclude accurate determination of ground water flow rate and direction.

(e) Background Water Quality - The owner or operator must establish background ground water quality in each hydraulically up gradient or background well and the downgradient wells for each of the monitoring parameters or constituents 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) for Class 1 landfills or as determined under Rule 22.523 and Rule 22.524 for Class 3 and other facilities required to monitor ground water quality. Background ground water quality may be established at wells that are not located hydraulically up gradient from the landfill if it meets the requirements of Rule 22.1202(a)(1). Background ground water quality is determined through the collection of, at a minimum, four (4) independent samples from each well (background and downgradient). To account for seasonal and temporal variations, each sample shall be collected quarterly unless another frequency has been approved by the Director.

(f) Conformance with Statistical Procedures - The number of samples collected to establish ground water quality data must be consistent with the appropriate statistical procedures determined pursuant to paragraph (g) of this section. The sampling procedures shall be those specified under Rule 22.1204(b) for detection monitoring, Rule 22.1205(b) and (d) for assessment monitoring, and Rule 22.1206(b) of corrective action.

(g) Statistical Method Selection - The owner or operator must specify in the operating record one of the following statistical methods to be used in evaluating ground water monitoring data for each constituent. The statistical test chosen shall be conducted separately for each constituent in each well.

(1) A parametric analysis of variance (ANOVA) 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 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).

(7) The most current statistical methods as recommended in EPA guidance publications.

(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.

(j) Sampling and Analysis Plans - Owners or operators shall develop and implement a Division approved site specific written sampling and analysis plan. The sampling and analysis plan and all reports to DEQ required under the sampling and analysis plan shall be certified by a qualified ground water scientist.

(3) Sample collection and laboratory quality assurance/quality control procedures;

(4) Ground water analytical data submittal procedures, which shall include provisions for the direct submittal of all analytical results from the contract, or independent third party laboratory to the Division;

(5) A method for statistically evaluating ground water analytical data for significant changes must be selected. The method must be tailored to fit the hydrogeology of the site. 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. If an SSI is confirmed, the permittee must notify the Division in accordance with Rule 22.1204(c). The GWMR shall be submitted to the SWMD within 90 days from the date of the last recorded sampling event.

(d) Assessment Monitoring Procedures - After obtaining the results from the initial or subsequent sampling events required in paragraph (b) of this section, the owner or operator must:

(1) Within fourteen (14) days, place a notice in the operating record identifying the Appendix 2 constituents that have been detected and notify the Director that this notice has been placed in the operating record;

(2) Within ninety (90) days, and on at least a quarterly basis thereafter, resample all wells specified by Rule 22.1202(a), conduct analyses for all assessment monitoring constituents (AMC) specified in Rule 22.1205(b) and record their concentrations in the facility operating record. At least one (1) sample from each well (background and downgradient) must be collected and analyzed during these sampling events. Following the first year of assessment monitoring, the Director may approve semiannual AMC sampling and analysis or an alternative frequency as specified below.

The Director may specify an alternative monitoring frequency during the active life (including closure) and the post closure period for the constituents referred to in this paragraph. The alternative frequency for the AMC list during the active life (including closure) shall be no less than annual. The alternative frequency shall be based on consideration of the factors specified in paragraph (c) of this section;

(3) Establish background concentrations for any constituents detected pursuant to paragraphs (b) or (d)(2) of this section; and

If a successful demonstration is made the owner or operator must continue monitoring in accordance with the assessment monitoring program pursuant to Rule 22.1205, and may return to detection monitoring if the assessment monitoring constituents are at or below background as specified in Rule 22.1205(e). Until a successful demonstration is made, the owner or operator must comply with Rule 22.1205(g) including initiating an assessment of corrective measures.

(h) Groundwater Protection Standard - The owner or operator must establish a ground water protection standard for each assessment monitoring constituents detected in the ground water. The ground water protection standard shall be:

(1) For constituents for which a maximum contaminant level (MCL) has been promulgated under Section 1412 of the Safe Drinking Water Act (codified) under 40 CFR Part 141, the MCL for that constituent;

(2) For constituents for which MCLs have not been promulgated, the background concentration for the constituent established from wells in accordance with Rule 22.1202(a)(1); or

(3) For constituents for which the background level is higher than the MCL identified under subparagraph (h)(1) of this section or health based levels identified under Rule 22.1205(i)(1), the background concentration.

(i) Alternative Groundwater Protection Standards - The Director may establish an alternative ground water protection standard for constituents for which MCLs have not been established. These ground water protection standards shall be appropriate health based levels that satisfy the following criteria:

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:

Click here to view image

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).

(c) Letter of Credit

(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

(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

(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:

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

(C) Operated at a deficit equal to five percent or more of total annual revenue in each of the past two fiscal years; 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:

(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.

(v) A local government must satisfy the requirements of the financial test at the close of each fiscal year. If the local government owner or operator no longer meets the requirements of the local government financial test it must, within 210 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 furnish those submissions to the Director for approval, and notify the Director that the owner or operator no longer meets the criteria of the financial test and that alternate assurance has been obtained.

(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:

(i) If the local government owner or operator does not assure other environmental obligations through a financial test, it may assure closure, post-closure care, and corrective action costs that equal up to 43 percent of the local government's total annual revenue.

(ii) If the local government assures other environmental obligations through a financial test, including those associated with UIC 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, it must add those costs to the closure, post-closure care, and corrective action costs it seeks to assure under this paragraph. The total that may be assured must not exceed 43 percent of the local government's total annual revenue.

(iii) The owner or operator must obtain an alternate financial assurance instrument for those costs that exceed the limits set in Rule 22.1405(f)(4)(i) and (ii).

(g) Corporate Guarantee

(1) An owner or operator may meet the requirements of this section by obtaining a written guarantee. 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.

(2) The guarantee must be effective and all required submissions placed in the operating record 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 post-closure care, or in the case of corrective action no later than 120 days after the corrective action remedy has been selected in accordance with the requirements of Rule 22.1208.

(3) The terms of 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 (performance guarantee); or

(B) Establish a fully funded trust fund as specified in paragraph (a) of this section in the name of the owner or operator (payment guarantee).

(ii) The guarantee will remain in force for as long as the owner or operator must comply with the applicable financial assurance requirements of this Section unless the guarantor sends prior notice of cancellation by certified mail to the owner or operator and to the Director. Cancellation may not occur, however, during the 120 days beginning on the date of receipt of the notice of cancellation by both the owner or operator and the Director, as evidenced by the return receipts.

(iii) If notice of cancellation is given, the owner or operator must, within 90 days following receipt of the cancellation notice by the owner or operator and the Director, obtain alternate financial assurance, place evidence of that alternate financial assurance in the facility operating record, and submit the alternate financial assurance to the Director for approval. 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. If the owner or operator fails to provide alternate financial assurance within the 90-day period, the guarantor must provide that alternate assurance within the next 30 days.

(5) The owner or operator is no longer required to meet the requirements of this paragraph (g) when:

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

(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. Cancellation may not occur, however, during the 120 days beginning on the date of receipt of the notice of cancellation by both the owner or operator and the Director, as evidenced by the return receipts.

(iii) If a guarantee is canceled, the owner or operator must, within 90 days following receipt of the cancellation notice by the owner or operator and the Director, obtain alternate financial assurance, place evidence of that alternate financial assurance in the facility operating record, and furnish the alternate financial assurance to the Director for approval.

(2) Recordkeeping and Reporting

(i) The owner or operator must place a certified copy of the guarantee along with the items required under Rule 22.1405(f)(3) into the facility's operating record 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 Rule 22.1208.

(ii) The owner or operator is no longer required to maintain the items specified in Rule 22.1405(h)(2) when:

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

(B) 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).

(iii) If a local government guarantor no longer meets the requirements of Rule 22.1405(f) 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 furnish the alternate financial assurance to the Director for approval. 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.

(n) Municipality or County Contract of Obligation

(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.

(3) The contract of obligation must be irrevocable and issued for a period of at least one 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).

(a) Incapacity of Permittee or Financial Institutions - The permit owner or operator must notify the Director by certified mail of the commencement of a voluntary or involuntary proceeding under Title 11 (Bankruptcy), U.S. Code, naming the permittee as debtor, within ten (10) days after commencement of the proceeding.

The permit owner or operator providing financial assurance by obtaining a surety bond, insurance, trust fund, or letter of credit will be deemed to be without the required financial assurance in the event of bankruptcy of the issuing institution, or a suspension or revocation of the authority of the institution issuing the surety bond, insurance, trust fund, or letter of credit to issue such instruments. The permittee must establish other financial assurance within sixty (60) days after such an event.

(b) Forfeiture of Financial Assurance - The Director may order that any financial assurance filed by the permittee pursuant to this paragraph for closure of a landfill or landfill increment be forfeited to the State if the Director determines that the permittee has failed to perform closure of the landfill or landfill increment in accordance with Rule 22.1301, post closure care of the landfill in accordance with Rule 22.1302, or corrective action in accordance with Rule 22.1208 when required to do so. Any such forfeiture action shall follow the procedures provided in this subparagraph.

(1) Upon determination that the permit owner or operator has failed to perform final closure, post closure care, or corrective action, or in the case of solid waste processing facilities, the clean up and removal of all waste from the site when required to do so, the Director shall cause a notice of violation to be served upon the permittee. Such notice shall be hand delivered or forwarded by certified mail. The notice of violation shall be in accordance with the requirements of Rule Number 8, Administrative Procedures, and shall specify in what respect the permittee has failed to perform as required. The permittee may request commission review and an adjudicatory hearing of the notice of violation in accordance with Rule Number 8 and the terms of the notice of violation.

(2) If the Director determines that the permit owner or operator has failed to perform or respond as specified in the notice of violation, The Director may issue a default administrative order of forfeiture of the financial assurance filed to guarantee such performance. Upon issuance, a copy of the order shall be hand delivered or forwarded by certified mail to the owner or operator and to the financial institutions, sureties or parties guaranteeing financial assurance.

(3) Upon the effective date of the order of forfeiture, the Director shall take legal action to collect the forfeiture.

(4) All fortified funds shall be deposited by the Director into the Solid Waste Performance Bond Fund to be utilized by the Director in performing proper closure, post closure care, or corrective action at the facility.

(c) Effect on Transfer of Permits - During permit transfers, existing financial assurance mechanisms and responsibilities shall remain in full force and effect until such time as the proposed new permit owner or operator has filed, in accordance with the requirements of this Chapter, the required replacement financial assurance mechanism(s). When acceptable replacement financial assurance have been filed with the Director, the Director shall cause to be released to the former permit owner or operator (or the issuing institution, if appropriate) the financial assurance that the permit owner or operator had filed.

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. Monitoring of other parameters may be required based on specific waste characteristics.
