Any additional parameters specified by the Department.

The Department may delete the requirement for any constituents where appropriate. Such deletions will be based on:

5.7.3.2.2.1 The results of leachate monitoring (constituent is not a significant constituent of the leachate),

5.7.3.2.2.2 Local geochemical considerations (immobility in subsurface), and

5.7.3.2.2.3 Other relevant factors.

Table 1

5.7.3.2.3 Test methods used to determine the parameters of Section 5.7.3.2.2 shall be those described in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", EPA Publication SW-846 [Third Edition (November 1986), as amended by Updates I (dated July 1992), II (dated September 1994), IIA (dated August 1993), IIB (dated January 1995), III (dated December 1996), and IIIA (dated April 1998)], or other tests approved in writing by the Department.

5.7.3.3 Monitoring frequency will be at least semiannual. An alternate frequency may be specified by the Department based on consideration of the following conditions:

5.7.3.3.1 Lithology of the aquifer and unsaturated zone,

5.7.3.3.2 Hydraulic conductivity of the aquifer and unsaturated zone,

5.7.3.3.3 Ground water flow rates,

5.7.3.3.4 Distance and travel time between the waste unit(s) and the downgradient monitor wells and possible points of exposure to any landfill derived contaminants in wells or receiving surface waters, and

5.7.3.3.5 Resource value of the aquifer.

5.7.3.4 The Department may observe the ground water sampling conducted by the permittee or his/her designee and may request split samples for analysis.

5.7.4 Data evaluation

5.7.4.1 The owner or operator must establish the background quality for each sampling parameter or constituent. The background quality is that which would be expected with no impact by contaminant releases from the waste cells.

5.7.4.2 The owner or operator must specify in the operating record the methods to be used for statistical evaluation of the monitoring data. These may include:

5.7.4.2.1 A tolerance or prediction interval procedure in which a range for each constituent is established from the distribution of the background data and the level of each constituent in each compliance (downgradient) monitor well is compared to the upper tolerance or prediction limit,

5.7.4.2.2 A control chart approach that plots concentrations of each constituent versus the background range, or

5.7.4.2.3 Any other statistical method chosen to meet the following requirements and approved by the Department:

5.7.4.2.3.1 Appropriate in distribution and number of available data to meet the requirements of the statistical test chosen;

5.7.4.2.3.2 Capable of limiting individual constituent comparisons to Type I error levels less than 0.01 or multiple constituent comparisons to Type I error levels less than 0.05, for each testing period. (This requirement does not apply to tolerance intervals, prediction intervals, or control charts.)

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

5.7.4.4 The owner or operator must determine whether or not there is a statistically significant increase over background values for each parameter or constituent required in the monitoring program by comparisons using the chosen method of evaluation. This evaluation must be performed within a reasonable period of sampling and analysis normally within 30 days of obtaining sampling results.

5.7.4.5 If any statistically significant increase occurs, the permittee must:

5.7.4.5.1 notify the Department and place the result in the operating record within 14 days, and

5.7.4.5.2 assess the probable accuracy and possible risk associated with the finding in the annual report.

5.7.4.6 Performance standards will be established at each site which are intended to provide adequate protection for human health and the environment. The performance standards may be proposed by the permittee, but must be approved by the Department, and shall be incorporated in the facility permit. In general, performance standards will be the maximum contaminant levels (MCLs) for public drinking water. However, the Department may specify performance levels which are more stringent to protect adjacent surface water (and prevent violation of surface water quality standards) or less stringent (where ground water at the site will not threaten existing or reasonably expected sources of drinking water or cause violation of surface water quality standards) as appropriate.

5.7.4.7 The points of compliance at which performance standards must be met must be no more than 150 meters from the edge of the furthest downgradient waste cell and must be on the waste management facility property.

5.7.4.8 If any release of contaminants from the landfill to the groundwater is detected, either by exceedance of background concentrations or violation of a performance standard in the downgradient wells (points of compliance), the owner or operator must:

5.7.4.8.1 Notify the Department and place the result in the operating record within 14 days,

5.7.4.8.2 Resample to confirm the result and/or demonstrate that the result was an error or that the increase was due to a source other than the permitted waste facility within 90 days,

5.7.4.8.3 Notify the Department of the result of confirmation within 14 days of availability of the result, and

5.7.4.8.4 If a release is confirmed, perform an assessment of corrective measure as described in Section 5.7.6.

5.7.5 Reporting

5.7.5.1 The owner or operator will compile and evaluate all ground water data within a reasonable period of time following sampling and analysis. A tabulation of water elevations and quality will be submitted to the Department within 60 days of each sampling event. Reports of any statistically significant increases in downgradient wells or violation of performance standards in wells or streams must be reported to the Department within 14 days as noted above.

5.7.5.2 An annual monitoring report must be submitted by the permittee to the Department which includes the following:

5.7.5.2.1 Maps showing the locations of sampling points, water elevations, and ground water flow directions and approximate rates for each sampling period;

5.7.5.2.2 Tabulation of all ground water levels and elevations, leachate volumes collected and treated and leachate and water quality data;

5.7.5.2.3 Presentation of statistical results and graphs depicting water quality parameter concentrations with time;

5.7.5.2.4 Identification of any statistically significant increases in compliance wells and/or exceedances of performance standards;

5.7.5.2.5 Confirmation results and conclusions related to the accuracy of these results and/or reasonable explanation for the results;

5.7.5.2.6 Recommendations for any changes in the monitoring program including changes in the number, location of sampling points, sampling frequency, parameters or procedures;

5.7.5.2.7 An evaluation of the significance of the results including whether they indicate a contaminant release has occurred and any recommendations for corrective measures, if appropriate.

5.7.5.3 In addition to paper copies of reports, the Department may require all or part of any required report to be submitted on machine-readable media in a format mutually acceptable to the Department and the permittee. With the approval of the Department, reports submitted on machine-readable media may be substituted for paper reports.

5.7.6 Assessment of Corrective Measures

5.7.6.1 An assessment (reassessment) of corrective measures by the owner or operator is required (within 90 days) of confirmation of a contaminant release or an exceedance of a performance standard. The owner or operator must perform this assessment which must include:

5.7.6.1.1 Identification of the nature and extent of the release (which may require construction and sampling of additional wells, analysis for additional constituents including those required for leachate, geophysical surveys and/or other measures);

5.7.6.1.2 Reassessment of contaminant fate and potential contaminant receptors (wells and/or receiving streams);

5.7.6.1.3 Evaluation of feasible corrective measures to:

5.7.6.1.3.1 Prevent exposure to potentially harmful levels of contaminants (exceeding performance standards);

5.7.6.1.3.2 Reduce, minimize or prevent further contaminant releases;

5.7.6.1.3.3 Reduce, minimize or prevent the offsite migration of contaminants.

5.7.6.1.4 The implementability (and time to implement) and costs of the feasible alternatives;

5.7.6.1.5 Recommendations for remedial action.

5.7.6.2 The owner or operator must present the results of the corrective measures assessment, including a proposed remedy, (with a schedule for initiation and completion) for public comment at a public meeting.

5.7.7 Selection of Remedy

5.7.7.1 Based on the results of the corrective measures assessment and public meeting, the owner/operator will select a remedial action.

5.7.7.2 Remedies must:

5.7.7.2.1 Be protective of human health and the environment;

5.7.7.2.2 Control source(s) of contaminant releases so as to reduce or eliminate (to the maximum extent practicable), further releases of contaminants that pose a threat to human health or the environment;

5.7.7.2.3 Comply with the site performance standards at the points of compliance (to the extent feasible); and

5.7.7.2.4 Comply with standards for the management of wastes.

5.7.7.3 The Department may determine that remediation of a contaminant release is not necessary if the permittee can demonstrate to the satisfaction of the Department (or the Department certifies that it is satisfied) that the ground water is not currently or reasonably expected to be a source of drinking water, will not migrate so as to threaten a source of drinking water or will not cause violation of surface water quality standards, (i.e., does not represent a significant threat to human health or the environment).

5.7.8 Implementation of Corrective Action

5.7.8.1 Based on the schedule established under Section 5.7.6.2 for initiation of remedial activities, the owner or operator must:

5.7.8.1.1 implement the corrective action remedy;

5.7.8.1.2 Take any interim measures necessary to ensure protection of human health and the environment (such as replacement of contaminated or imminently threatened water supplies); and

5.7.8.1.3 Perform ground water and/or surface water monitoring to demonstrate the effectiveness of the remedy including whether or not compliance is achieved with the performance standards.

5.7.8.2 If the owner or operator determines, based on information obtained after implementation of the remedy has begun or other information that compliance with remediation objectives (including achievement of performance standards) cannot be practically achieved with the remedy selected, the owner or operator must notify the Department and request authorization to proceed with another feasible method consistent with the overall objective of the remedy.

5.7.8.3 If the permittee determines that compliance with remedial action objectives (Section 5.7.7) cannot be practically achieved, the permittee must notify the Department and implement alternate methods to control exposure of humans or the environment to residual contamination and implement alternative control measures.

5.7.8.4 Remedies selected shall be considered complete when:

5.7.8.4.1 All actions required to implement the remedy have been achieved; and

5.7.8.4.2 The ground water protection standards or alternate requirements agreed upon have been achieved for a period of three years or alternate period approved by the Department.

5.7.8.5 Upon completion of the remedy, the owner or operator must notify the Department that a certification of the remedy has been completed in compliance with the requirement and placed in the operating records. This certification must be signed by a Professional Geologist registered in Delaware.

5.7.8.6 Upon completion of the remedy, the owner or operator will continue ground water monitoring as required by provisions of Section 5.7.3 and approved by the Department.

11.13.1 Treatment of infectious waste must be conducted in a manner which:

11.13.1.1 Eliminates the infectious potential of the waste. A treatment process eliminates the infectious potential of infectious waste if the owner or operator of a treatment unit demonstrates that an Initial Efficacy Test and Periodic Verification Test(s) have been completed successfully.

11.13.1.1.1 Successful completion of an Initial Efficacy Test is demonstrated by a 6-log reduction/kill of test microorganisms. For a thermal unit that maintains the integrity of container, a 6-log kill of indicator microorganism spores may be used as an alternative test.

11.13.1.1.2 Successful completion of a Periodic Verification Test is demonstrated by:

11.13.1.1.2.1 a 6-log kill of test microorganisms or indicator microorganism spores as provided in Subsection 11, Part 1, L.1.a; or

11.13.1.1.2.2 a minimum 3-log kill of indicator microorganism spores that have been correlated with a 6-log kill of test microorganism; or

11.13.1.1.2.3 an alternate method submitted to and approved by the Department.

11.13.1.2 Disposes treatment residues in accordance with these regulations.

11.13.1.3 Provides for quality assurance programs that must include, at a minimum, a written plan that:

11.13.1.3.1 Designates responsibility to personnel.

11.13.1.3.2 Describes parameters that must be monitored to insure effectiveness of the treatment process.

11.13.1.3.3 Identifies monitoring devices.

11.13.1.3.4 Ensures that monitoring devices are operating properly.

11.13.1.3.5 Establishes appropriate ranges for operating parameters.

11.13.1.3.6 Identifies person(s) who shall collect and organize data for inclusion in operating records.

11.13.1.3.7 Identifies person(s) who shall evaluate any discrepancies or problems.

11.13.1.3.8 Identifies person(s) who shall propose actions to correct problems identified, and

11.13.1.3.9 Identifies person(s) who shall assess actions taken and document improvement.

11.13.1.4 Provides for periodic biological testing, where appropriate, that demonstrates proper treatment of the waste.

11.13.1.5 Provides for assurances that clearly demonstrate that infectious waste has been properly treated; and

11.13.1.6 Is in compliance with all federal, state and local laws and regulations pertaining to environmental protection.

11.13.2 Initial Efficacy Test

11.13.2.1 The manufacturer, owner, or operator of a treatment unit shall conduct an Initial Efficacy Test, pursuant to Appendix A of this Section, for each model prior to its operation. If significant mechanical changes are made to a treatment unit, the Initial Efficacy Test must be repeated. The treatment units are considered to be the same model if they:

11.13.2.1.1 Are manufactured by same company,

11.13.2.1.2 Have the same company name, and

11.13.2.1.3 Have no significant mechanical changes.

11.13.2.2 The Initial Efficacy Test shall be conducted using option 1, 2 or 3 as described in Appendix A of this Section, using the challenge loads listed in Table C of Appendix A, or by an equivalent procedure that meets the requirements of the Initial Efficacy Test and has been approved by the Department. If any of the challenge loads fails the Initial Efficacy Test, the operating conditions must be revised and the Initial Efficacy Test must be repeated for all challenge loads. The Initial Efficacy Test must also meet the requirements of this Section.

11.13.2.3 Composition of challenge loads

11.13.2.3.1 For treatment units designed to treat all types of infectious wastes, all three types of challenge loads must be used in conducting the Initial Efficacy Test. The three (3) types of challenge loads represent infectious waste with a high moisture content, low moisture content and high organic content. The quantity of each challenge load must equal 100% of the maximum capacity of the treatment unit.

Each challenge load must consist of a minimum 5% (by weight) of each of the following categories: blood/broth cultures, fibers, metals, sharps, plastics, pathological waste, glass, non-woven fibers, and bottles of liquids. Table C of Appendix A contains the moisture and organic content requirements that must be met in each type of challenge load.

11.13.2.3.2 For treatment units designed to treat select categories of infectious waste (e.g., sharps treatment unit), modification in the composition of the challenge load(s) may be used if approved by the Department in writing.

11.13.2.4 The Initial Efficacy Test must be conducted under the same operating conditions under which the treatment unit operates on a day-to-day basis. The feed rate for the treatment unit must remain constant throughout the Initial Efficacy Test. This feed rate must never be exceeded during the operation of the treatment unit.

11.13.2.5 The Initial Efficacy Test must be performed so that:

11.13.2.5.1 Each container of the test microorganisms and/or indicator microorganism spores is placed in the load to simulate the worst case scenario (i. e., that part of load that is the most difficult to treat). For example, the worst case scenario for an autoclave would be to place the container(s) of test microorganisms and/or indicator microorganism spores within a sharps container that must in turn be deposited in a plastic biohazard bag that is then located centrally within the challenge loads.

11.13.2.5.2 Test microorganisms and/or indicator microorganisms must be cultured and enumerated in accordance with instructions provided by the supplier of micro-organisms and Standard Methods for the Examination of Water and Wastewater.

11.13.2.6 A Document of Initial Efficacy Test must be retained in the treatment facility, and made available during normal business hours for inspection and photocopying by an authorized representative of the Department. The Document of Initial Efficacy Test must include at the minimum:

11.13.2.6.1 A detailed description of the test procedures used, including all test data generated, with descriptions of data handling, and interpretation of final test results.

11.13.2.6.2 A detailed description and verification of the operating parameters (e.g., temperature, pressure, retention times, chemical concentrations, irradiation dose, and feed rates).

11.13.2.6.3 A description of quality assurance/quality control procedures and practices for the culture, storage and preparation of test and/or indicator microorganisms (including, but not limited to, organism history, source, stock culture maintenance, and enumeration procedures). The purity of the test microorganisms and/or indicator microorganism spores must be certified by a commercial or clinical laboratory.

11.13.3 Periodic Verification Test(s)

11.13.3.1 The effectiveness of the treatment unit shall be verified by conducting Periodic Verification Test(s) which must be carried out in accordance with this Subsection.

11.13.3.2 Periodic Verification Test(s) must be conducted quarterly or more frequently if required by the permit or recommended by the manufacturer.

11.13.3.3 The manufacturer, owner, or operator of a treatment unit must perform Periodic Verification Test(s) that satisfy at least one (1) of the following:

11.13.3.3.1 Passing the Initial Efficacy Test by using option 1, 2 or 3 of appendix A of this part (whichever is applicable). The three challenge loads described in Appendix A, Table C, do not need to be used. The test microorganism or indicator micro-organisms must be placed in a representative load in accordance with Subsection 11, Part 1, 11.13.2.5.1. For example, an autoclave may use option 3 (e.g., demonstrate at a minimum the destruction of one million Bacillus stearothermophilus spores) to meet the Periodic Verification Test requirement. In the case of an incinerator a stainless steel pipe with threaded ends and removable caps lined with ceramic insulation may be used to contain a glass culture vial with a Bacillus subtilis spores strip. The pipe with the spore strips may be placed in the load of infectious waste for the Periodic Verification Test. After the treatment, the pipe with the spore strips may be recovered and the spores may be cultured to assess whether, at a minimum, one million spores have been destroyed to meet the Periodic Verification Test(s) requirement.

11.13.3.3.2 Correlating the log kill (L) of the test microorganisms in the Initial Efficacy Test to an equivalent log kill (T) of indicator microorganism spores in accordance with Appendix B. The equivalent log kill (T) of indicator microorganism spores must be used for all subsequent Periodic Verification Tests. The correlation must be done with three challenge loads identified in Table C of Appendix A (See Subsection 11, Part 1, 11.13.3.4.3 below for further requirements).

11.13.3.3.3 Submitting to and obtaining written approval by the Department for a procedure that is equivalent to Subsection 11, Part 1, 11.13.3.3.1 and 11.13.3.3.2. Examples of alternatives include, but are not limited to, use of another indicator microorganism, or measurement of disinfectant concentrations in the treated residue. For incinerators only, an example of an alternative is visually inspecting the ash from each load of treated infectious waste to ensure that all infectious waste within the load is completely combusted. The approval of an alternative by the Department may require more frequent testing and/or monitoring of the treatment unit.

11.13.3.4 If correlation is being used for the Periodic Verification Test, (i.e., the correlation of log kill (L) of the test microorganisms with equivalent log kill (T) of the indicator microorganism spores) the following procedures apply:

11.13.3.4.1 At a minimum, an initial population of one million indicator microorganism spores per gram of waste solids in each challenge load must be used.

11.13.3.4.2 The fraction of surviving indicator microorganism spores that correlates to a log kill (L) of six (6) for each test microorganism must be used for future Periodic Verification Test(s). [For example, if a log kill (L) of four (4) for the indicator microorganism spores per gram of waste solids is achieved during this demonstration, then a population of 10,000 of indicator microorganism spores must be used in future Periodic Verification Test(s).] Challenge loads described in Appendix A, Table C, do not need to be used. The test microorganism or indicator microorganism spores must be placed in a representative load in accordance with Subsection 11, Part 1, 11.13.2.5.1.

11.13.3.4.3 An equivalent log kill (T) of at least three (3) for the indicator microorganism spores must be achieved to ensure that all test microorganisms are destroyed.

11.13.3.4.4 Test microorganisms and/or indicator microorganism spores must be cultured and enumerated in accordance with instructions provided by the supplier of the microorganisms and Standard Methods for the Examination of Water and Wastewater.

11.13.3.4.5 The Periodic Verification Test and Initial Efficacy Test may be run concurrently to verify the correlation.

11.13.3.5 If a load of infectious waste fails a Periodic Verification Test, the Periodic Verification Test(s) must be repeated. The operator shall implement the quality assurance program and contact the manufacturer. If applicable, identify and correct the exact problem(s) until the unit can eliminate the infectious potential of the infectious waste. If the operating parameters are altered another Initial Efficacy Test must be performed to demonstrate the effectiveness of the unit and, if applicable, another Periodic Verification Test correlation, pursuant to Subsection 11, Part 1, 11.13.3.3 must be repeated. Loads of infectious waste that were processed prior to receiving the results showing a failure of Periodic Verification Test are considered treated. A second Periodic Verification Test must be run immediately after the first Periodic Verification Test indicates failure. The second Periodic Verification Test is to determine whether or not the treatment unit is eliminating the infectious potential of the waste. After the second Periodic Verification Test shows a failure of the treatment unit, any waste processed after the first detection of failure is considered infectious waste and must be managed accordingly.

11.13.3.6 Results of the Periodic Verification Test(s) must be received, verified and made available for inspection by the Department within 2 weeks of when the test was conducted. When a Periodic Verification Test is used to confirm the failure of a treatment unit, the results of the Periodic Verification Test(s) must be made available in accordance with the requirements of subsection h below.

11.13.3.7 A Document of Correlating Periodic Verification Demonstration must be prepared by and retained for at least three (3) years at the treatment facility during normal business hours for inspection by the Department. The Document of Periodic Verification Demonstration must include, at a minimum:

An evaluation of the test results must include all test data generated, a description of data handling, and a presentation and interpretation of test results.

11.13.3.7.2 A detailed description and verification of the operating parameters (e. g., temperature, pressure, retention times, chemical concentrations, irradiation dose, and feed rates).

11.13.3.7.3 A description of quality assurance/quality control procedures and practices for the culture, storage and preparation of test and/or indicator microorganisms (including, but not limited to, organism history, source, stock culture maintenance, and enumeration procedures). The purity of the test microorganisms and/or indicator microorganism spores must be certified by a commercial or clinical laboratory.

11.13.3.8 Records of Periodic Verification Test(s) must be prepared and retained for at least three (3) years at the treatment facility, and made available at the treatment facility during normal business hours for inspection by the Department. These records will include, at the minimum:

11.13.3.8.1 The date(s) on which the Periodic Verification Test(s) were performed.

11.13.3.8.2 Operating parameters (e.g., temperature, pressure, retention times, chemical concentrations, irradiation dose and feed rates).

11.13.3.8.4 Evaluation of test results.

11.13.3.8.5 The name(s), date, signature(s) and title(s) of Person(s) conducting the Periodic Verification Test(s).

11.13.3.9 Periodic Verification Test(s) must be conducted under the same operating conditions under which the treatment unit operates on day-to-day basis. The feed rate for the treatment unit is the maximum feed rate at which the unit operates on day-to-day basis. The feed rate must remain constant throughout the Periodic Verification Test(s). This feed rate must never be exceeded during the operation of the treatment unit.

Section 11, Part 1

Appendix A

Initial Efficiency Test Procedures

The manufacturer, owner, or operator of an infectious waste treatment unit must carry out an Initial Efficacy Test by using Option 1, 2, or, 3 below, as appropriate for the type of unit, or other procedures, if approved in advance by the Department.

1. Option 1

This option consists of two (2) Phases:

a. Phase 1: Determining the dilution of each test microorganism from the treatment unit for each challenge load (Types A through C) identified in Table C of this Appendix.

(1.) Prepare and sterilize by autoclaving two (2) challenge loads of Type A as identified in Table C. Reserve one challenge load for Phase 2.

(2.) Process each test microorganism in separate runs through the treatment unit. Prior to each run, determine the number of viable test microorganisms in each container, in accordance with applicable manufacturer's recommendations and Standard Methods for the Examination of Water and Wastewater.

(3.) Process each challenge load within thirty (30) minutes after introducing the container of test microorganism into the treatment unit. The container of test microorganisms and the challenge loads must be processed together without the physical and/or chemical agents designed to kill the test microorganisms. For example, in treatment units that use chemical disinfectant(s), an equal volume of liquid (e.g., sterile saline solution (0.9%, volume/volume), phosphate buffer solution, or tap water) must be substituted in place of the chemical disinfectant(s).

(4.) Obtain at least five (5) representative grab samples from the processed residue of each challenge load in accordance with Test Methods for Evaluating Solid Waste Physical/Chemical Methods (SW-846). The number of viable test microorganisms in each grab sample must be determined in accordance with applicable manufacturer's recommendations and Standard Methods for the Examination of Water and Wastewater.

(5.) Calculate the effect of dilution for the treatment unit as follows:

SA = Log N0A - LogN1A: where Log N1A ³ ≥6

where: SA is the log of the number of viable test microorganisms (CFU/gram of waste solids) that were not recovered after processing challenge load Type A.

N0A is the number of viable test microorganisms (CFU/gram of waste solids) introduced into the treatment unit for challenge load Type A.

N1A is the number of viable test microorganisms (CFU/gram of waste solids) remaining in the processed residue for challenge load Type A.

If Log N1A is less than 6, then the number of viable test microorganisms introduced into the treatment unit must be increased and steps (1) through (6) in Phase 1 must be repeated until LogN1A is ³≥6. N0A is the inoculum size for challenge load Type A in Phase 2 below.

(6.) Repeat steps (1) through (5) in Phase 1 for challenge loads of infectious waste for Type B and C identified in Table C of this Appendix to determine the effect of dilution (SB and SC respectively).

b. Phase 2: Determining the log kill of each test microorganism in each challenge load (Type A through C) identified in Table C of this Appendix.

(1.) Using the inoculum size (N0A) determined in Phase 1 above, repeat Phase 1 steps (1) through (5) under the same operating parameters, except that the physical and/or chemical agents designed to kill the test microorganisms must be used.

(2.) Calculate the effectiveness of the treatment unit by subtracting the log of viable cells after the treatment from the log of the viable cells introduced into the treatment unit as inoculum, as follows:

LA = Log N0A - SA - Log N2A ³≥6

where: LA is the log kill of the test microorganisms (CFU/gram of waste solids) after treatment in the challenge load Type A.

N0A is the number of viable test microorganisms (CFU/gram of waste solids) introduced into the treatment unit as the inoculum for challenge load Type A as determined in Phase 1 above.

SA is the log of the number of viable test microorganisms (CFU/gram of waste solids) that were not recovered after processing challenge load Type A in Phase 1 above.

N2A is the log of the number of viable test microorganisms (CFU/gram of waste solids) remaining in the treated residue for challenge load Type A.

(3.) Repeat steps (1) and (2) in Phase 2 for challenge loads Types B and C identified in Table C of this Appendix to determine the effectiveness of the treatment unit (LB and LC respectively).

2. Option 2:

a. Place one microbiological indicator assay containing one of the test microorganisms at numbers greater than one million in a sealed container that remains intact during the treatment. The inside diameter of the container must be no larger than required to contain the assay vial(s). The vial(s) must contain the test microorganisms.

b. Place the container of test microorganisms within a Type A challenge load as identified in Table C of this Appendix.

c. Process the load.

d. Calculate the effectiveness of the treatment unit by subtracting the log of viable cells after treatment from log of viable cells introduced into the treatment unit as inoculum, as follows:

LA = Log N0 - Log N2A³ ≥6

where: LA is the log kill of the test microorganisms (CFU/gram of waste solids) after treatment in the challenge load Type A.

N0 is the number of viable test microorganisms (CFU/gram of waste solids) introduced into the treatment unit as the inoculum.

N2A is the log of the number of viable test microorganisms (CFU/gram of waste solids) remaining in the treated residue for challenge load Type A.

e. Repeat steps a through d in this option for challenge loads Types B and C identified in Table C of this Appendix to determine the effectiveness of the treatment unit (LB and LC respectively).

3. Option 3:

a. Place one microbiological indicator assay containing at least one million spores of one of the indicator microorganisms listed in Table B of this Appendix, in a sealed container that remains intact during treatment. The inside diameter of the container must be no larger than required to contain the assay vial(s).

b. Place the container of the indicator microorganisms within a Type A challenge load as identified in Table C of this Appendix.

c. Process the load.

d. Calculate the effectiveness of the treatment unit by subtracting the log of viable cells after treatment from log of viable cells introduced into the treatment unit as inoculum, as follows:

LA = Log N0 - Log N2A³≥6

where: LA is the log kill of the test microorganisms (CFU/gram of waste solids) after treatment in challenge load Type A.

N0 is the number of viable indicator microorganisms (CFU/gram of waste solids) introduced into the treatment unit as the inoculum.

N2A is the log of the number of viable test microorganisms (CFU/gram of waste solids) remaining in the treated residue for challenge load Type A.

e. Repeat steps a through d in this option for challenge loads Types B and C identified in Table C of this Appendix to determine the effectiveness of the treatment unit (LB and LC, respectively).

Correlating Periodic Verification Procedures

1. Use a certified microbiological indicator assay containing the test microorganisms and indicator microorganism spores.

2. Place the test microorganisms and indicator microorganism spores into sealed containers that remain intact during treatment.

3. Place a container of the test microorganisms and indicator microorganism spores in each challenge load (as described in Appendix A, Table C) to simulate the worst case scenario (i.e., that part of load that is the most difficult to treat). For example, the worst case scenario for an autoclave would be to place the container of test microorganisms and indicator microorganism spores within a sharp container that must in turn be deposited in a plastic biohazard bag that is then located centrally within the treatment unit.

4. Determine the effectiveness of the treatment unit by calculating the log kill (L) of the test microorganisms in accordance with Option 2 of Appendix A. The equivalent kill (T) of the indicator microorganism spores is calculated by subtracting the log of viable cells after treatment from the log of viable cells introduced into the treatment unit as inoculum as follows:

TA = Log N0 - Log N2A³ ≥3

where: TA is the equivalent log kill of the viable indicator microorganisms (CFU/gram of waste solids) after treatment in the challenge load Type A.

N0 is the number of viable indicator microorganism spores (CFU/gram of waste solids) introduced into the treatment unit as the inoculum (³≥6).

N2A is the number of viable indicator microorganisms (CFU/gram of waste solids) remaining after treatment in challenge load Type A.

5. Repeat steps 1 through 4 for challenge loads Types B and C identified in Table C of Appendix A to determine the correlation between the log kill of the test microorganisms and equivalent kill of the indicator microorganism spores (LB and LC, respectively).

11.1 General Provisions

11.1.1 Municipal solid waste (MSW) ash is considered a hazardous waste, as defined in the Delaware Regulations Governing Hazardous Waste (DRGHW), unless the generator of the ash can demonstrate that the ash is not a hazardous waste. In order to make such a demonstration, the owner or operator of the generating facility must show that the ash does not exhibit the Toxicity Characteristic (TC) as described in DRGHW, §261.24. Any person desiring to make such a demonstration shall develop and implement a sampling and analysis plan designed to provide reliable information on the chemical properties of the ash. The plan shall be submitted to the Solid and Hazardous Waste Management Branch as a part of the facility's application for a Solid Waste Facility permit. The facility will not be permitted to operate until the Department has approved the plan.

11.1.2 The sampling and analysis plan shall include the following:

11.1.2.1 A detailed description of the sampling protocol (how and where samples will be collected, how many samples will be collected, how samples will be composited, how samples will be handled and stored, etc.)

11.1.2.2 A description of the analyses that will be performed on the samples.

11.1.2.3 A description of the procedures that will be used to ensure the quality of the sampling and analysis data.

11.1.3 The owner or operator of a facility in Delaware desiring to process MSW ash generated in another state must first receive written approval from the Department to accept MSW ash from that generator. To receive such an approval a person must:

11.1.3.1 Demonstrate, to the Department's satisfaction, that the ash does not exceed the levels specified in the TC; and

11.1.3.2 Develop, and receive Department approval of, a plan for sampling and analysis of the incoming MSW ash.

11.2 Sampling

11.2.1 This subsection describes the minimum amount of sampling that the Department deems appropriate for MSW ash generated by facilities that meet the following two assumptions:

11.2.1.1 The waste feed prior to incineration is not segregated by type of generator, and

11.2.1.2 The ash generated is not separated by size during storage or disposal.

If either of these two assumptions is not valid, then a facility-specific sampling and analysis program shall be designed by knowledgeable personnel and shall be implemented after receiving Department approval.

11.2.2 The sampling strategy shall be sufficient to enable the facility owner or operator to assess the properties of the ash and to ascertain its variability over time.

11.2.3 The sampling strategy shall provide for reassessment of the ash at least quarterly, in accordance with a Department-approved schedule. In determining how often to recharacterize the ash, the generator shall consider all facility-specific and external factors that could cause the ash properties to vary. These factors include:

11.2.3.1 Changes in the composition of the waste (e.g., new types of industries moving into the area, institution of recycling programs in the collection area, seasonal changes affecting population or waste composition).

11.2.3.2 Changes in plant design (e.g., addition of dry scrubber, addition of quench tank).

11.2.3.3 Significant changes in plant operating conditions (e.g., increase in combustion time or temperature, change in lime utilization rate).

11.2.4 The sampling strategy shall include the following steps:

11.2.4.1 Determine the most convenient location for sampling. In situations where the sampling can be conducted either from transport vehicles or from the waste conveyance device, the Department recommends sampling from the transport vehicle (i.e. dump truck, barge).

11.2.4.2 Construct a sampling device (trough, bucket, shovel, thief, etc.) to be used to gather a grab sample of the entire depth of the hopper, pile, or truck load, or the entire width of the belt conveyor, drag chain flight, or vibrating conveyor. ASTM standards for sampling unconsolidated waste materials from trucks may be used for guidance if the ash is to be sampled from trucks.

11.2.4.3 If a conveyor is to be the sample location, collect the entire width of the conveyor at a fixed point each hour for eight (8) hours. If trucks are to be sampled, randomly select eight trucks to sample during the eight-hour period. In certain situations, where fewer than eight truckloads are generated, a different schedule may be necessary (e.g., less than one truck per hour). Composite all samples for the period into an eight-hour composite. Containerize, label, and set aside for further processing.

11.2.4.4 Collect a second eight-hour composite during the course of the work day. The second composite should be collected during a different shift from the first composite.

11.2.4.5 For an initial waste characterization, collect samples each day for a minimum of one week's operation (i.e., fourteen composite samples).

11.3 Analysis

11.3.1 Each composite sample shall be tested, using Method 1311 [Toxicity Characteristic Leaching Procedure (TCLP)], and the results analyzed, to determine whether the ash passes or fails the TC as defined in the DRGHW, §261.24.

11.3.2 All testing shall be performed following the specific procedures described in "Test Methods for Evaluating Solid Waste" (SW-846).

11.3.3 The testing shall be performed by an independent laboratory.

11.3.4 In lieu of TCLP, testing for total concentration of constituents (i.e., the contaminants listed in DRGHW, §261.24, Table 1) may be performed. If no constituent is present at a concentration exceeding the TC regulatory limit, the waste may be considered non-hazardous. However, if the concentration of any constituent exceeds the TC regulatory limit, TCLP must be performed to determine whether the waste is hazardous.

11.3.5 If it has been demonstrated that none of the organic constituents listed in DRGHW, §261.24, Table 1, is present in the ash at a detectable level, the ash need not be routinely tested for the organics.

11.4 Quality Assurance And Quality Control

The sampling and analysis plan shall include:

11.4.1 A detailed description of the steps that will be taken to ensure quality control, and

11.4.2 A provision for appointing a knowledgeable person to oversee the sampling and analysis program to ensure that all procedures are followed.

11.5 Data Evaluation

The following approach shall be used in evaluating the data to determine whether the ash passes or fails the TC (see SW-846, Chapter Nine, Tables 9-1 and 9-2 for statistical formulas to use in making the calculations):

11.5.1 Determine the mean TC concentration (x) of the fourteen eight-hour composite samples for each regulated analyte (equation 2a of Table 9-1).

11.5.2 Determine the standard deviation(s) of the data employed to calculate the mean (i.e., the individual composite results) (equation 3a and 4 of Table 9-1).

11.5.3 Determine the upper bound of the 90 percent (one-sided) confidence interval for the mean for each analyte (equation 6 of Table 9-1).

If the upper bound of the interval is below the applicable regulatory threshold for all analytes listed in DRGHW, §261.24, then the waste passes the TC. If the upper bound of the interval is above the applicable regulatory threshold for any analyte listed in DRGHW, §261.24, then the waste fails the TC.

If any provision of these regulations, or the application of any provision of these regulations to any person or circumstance, is held invalid, the application of such provision to other persons or circumstances, and the remainder of these regulations, shall not be affected thereby.
